Precautions for use of plastic granulator

The correct operation of the plastic granulator helps to extend its life. However, the use of plastic granulator does not receive enough attention in our daily life, and it also causes some unnecessary problems. Then we use plastic. What issues should you pay attention to when you are using a grain machine?

1. The plastic granulator should be operated strictly in accordance with the operating procedures and must not be operated in violation of the non-operating station. To ensure the reliability of the safety device, the safety protection measures of the machine must not be destroyed in pursuit of efficiency.

2. When the plastic granulator is operated, the material temperature does not reach the set temperature, and when the holding time is insufficient, the screw is not allowed to be turned on.

3. Operate by an operator who is trained and familiar with the structural performance and operating procedures of the plastic granulator.

4, pay attention to fire safety, fire extinguishers should be placed near the equipment using heat transfer oil.

5. In case of malfunction or abnormal situation, the relevant personnel must be reported and handled by professional maintenance personnel. If an abnormal phenomenon affecting safety is found, immediately press the emergency stop switch.

6. Do not use low-quality materials with metal impurities or sediment. Do not place metal objects that may fall into the vicinity of the feed port to prevent the screw or barrel from being worn or jammed or damaged.

Large rotary dryer equipment

With the development of the dryer industry, sawdust and wood powder have become the wooden materials widely used by users today. As a product of the development of the dryer industry, large rotary dryer equipment has become a sought after device for users. For the users, the selection of the equipment in the early stage of production can better carry out the later work. How to choose the large rotary dryer equipment?

First, the reason why the new rotary dryer is favored by many people is that its drying effect is far better than the previous models. In addition, the industry demand for wood powder raw materials is increasingly demanding product quality. High, that is to say, these customers are more willing to choose high-quality wood powder when purchasing wood powder raw materials. However, many rotary dryers are prone to paste phenomenon due to design defects. Unwilling to buy;

Second, some users have just started to use the rotary dryer, often appear paste, blockage, etc., in fact, most of them are caused by unskilled handling, and now with the rise of the automation industry, the new rotary dryer now Most of them are equipped with a special control platform. The operators only need to follow the operation prompts to carry out the corresponding process execution, which greatly reduces the production accidents caused by the improper operation;

 Third, it is to see if the overall function of this rotary dryer is comprehensive. In general, today's users are hard to do business all year round due to the processing of wood powder raw materials. After all, many customers' orders are seasonal, so the rotary dryer can be used all year round. If you don't stop, you must consider the functionality of the rotary dryer. The new rotary dryer produced by Heying Machinery takes into account these conditions. It can not only dry wood powder but also has similar properties to wood powder. Can be processed with a wood powder dryer;

Fourth, because many customers who order wood powder raw materials in the market are in high demand, but the time required for the goods is relatively tight, so the output of the rotary dryer determines whether it is favored by users, and nowadays a variety of rotary drying The machine can't be done too much by the control of the drying machine principle, otherwise the drying effect will be greatly reduced. Now the new rotary dryer produced by Heying Machinery has broken the technical limitation and will be sorted out with the practice data in the future. And the process to improve the size of the rotary dryer will not be far away;

For everyone, buying large-scale equipment such as a rotary dryer is for long-term investment. I also hope that my business is getting better and better, and the business volume is increasing. Therefore, if a rotary dryer does not meet the above requirements, The requirements of the four aspects are basically difficult for the user to use for a long time, and even if there is no advantage in competing with other people's products, the wood powder drying process will be withdrawn early.

Details in the charcoal making machine assembly line

With the development of the charcoal making machine industry, large-scale charcoal making machine equipment has become the main equipment for the production of charcoal. In the usual production process, there are often some details that are easily overlooked, which have not caused the attention of the relevant personnel, not only affecting the normal production work but also causing more serious production accidents or economic losses after a long time, then the large charcoal making machine What are the details that are easily overlooked in the assembly line?

First, we must pay attention to electricity. In the production process of charcoal making machine, the safety hole that is easily overlooked is electricity. The rod forming equipment of charcoal making machine uses an electric motor, which uses 380V electric power, and the body is made of steel material with good heat dissipation performance, but At the same time, it is also electrically conductive. Many operators do not notice this when a fault occurs and accidentally touch an electric shock event.

The solution to this type of security vulnerability is to install a leak protection device at the power supply or install an air protection switch at the bus to avoid accidental electric shock. Secondly, a grounding device should be installed on the motor body to avoid leakage.

Second: pay attention to fire prevention. The charcoal making machine is easily overlooked in the production of safety holes and fires. The carbonization furnace is formed by carbonizing the formed carbon rods through high-temperature combustion. Generally, the central hole portion will have Mars. It is necessary to pour Mars out to be completely cooled before carrying out the stacking. Do not accumulate indoors, which may cause fire.

Third, reasonable temperature control. The production activity of the charcoal production line is inseparable from high temperature. When the mechanism carbon is molded, it needs to be extruded under high temperature and high-pressure environment. It is completed by the heating coil of the charcoal production line and is heated by the heating coil. Heating to 260-350 degrees Celsius can ensure that the fabricated carbon rods reach the required density. The point to note is that the charcoal production line should be preheated and then discharged for production and processing.

 Fourth, proficient in the living process and raw material moisture. The mechanism of charcoal produced depends on the equipment and process, and depends on the size of the water contained in the raw materials. Generally, the moisture content of the raw material is less than 12%, but it is also greater than 6%, so as to greatly avoid the resulting salary bar being easily broken due to excessive moisture content. These are just some of the details in the process of making rods in the production line of charcoal making machines. They are also a key part. The good and bad of the rods also affect the effect of carbonization in the future. Therefore, in each production process, we must judge according to the production experience. And adjustments.

Inspection and repair of new charcoal machine equipment

Nowadays, due to the widespread use of charcoal, many traditional charcoal manufacturers have started to use charcoal production equipment for energy saving and environmental protection. However, in the actual production process, users did not timely repair the charcoal making machine equipment. Maintenance, resulting in a greatly reduced working life of the equipment, then how to judge whether the new charcoal making machine equipment needs maintenance?

Here are a few ways to determine if a charcoal maker needs repair:

1. If the rod speed of the charcoal stick system is greatly reduced, the efficiency will be significantly reduced, and the quality of the rod will not be very good, and the carbon rod will loosely slag, which is due to the long-time working internal pressing system of the rod system. If the work efficiency is reduced, the rod system should be cleaned and added with oil, which can improve the lubrication of the hydraulic shaft.

2. The dryness of the raw materials does not meet the requirements, which will cause the rod making the machine to often get stuck. This situation indicates that the charcoal making machine needs maintenance, mainly because the temperature of the dryer does not meet the specified requirements, resulting in the raw materials. The moisture cannot be fully dried, and the wet raw material is directly stuck in the rod making system after entering the rod making machine, causing the rod making machine to be stuck.

3. After the charcoal making machine is formed into a rod, the carbon rods are separated from each other and cannot be evenly connected together. This situation indicates that the hydraulic system of the charcoal making machine needs to be maintained and the pressure of the hydraulic system cannot meet the requirements. The structure of the charcoal is not stable, and a section of the knot is detached when the stick is released.

Ways to overhaul charcoal making machine equipment:

1. Routine inspection of drying facilities: Airflow dryer is the role of “playing” charcoal drying process, and whether the airflow dryer process meets the standard is inseparable from the normal use of the supporting facility hot blast stove, only the hot blast stove Under normal operating conditions, the quality standards of the charcoal drying process can be effectively controlled; for this, we must carefully check whether the fan of the hot blast stove is flexible and whether the ventilation pipe is blocked, which is the main factor affecting the normal operation of the hot blast stove.

2. Routine inspection of crushing supporting facilities: raw material crushing is the only way for charcoal production. We must control the raw material crushing at the appropriate particle size to ensure the charcoal quality made by the charcoal making mechanism, and the raw material granularity is naturally indispensable. For the matching blades, we should regularly check the smashing blades for gaps and avoid the blunt blades affecting the pulverization of the charcoal raw materials.

3, the routine inspection of the rod supporting facilities: rod forming is a major feature of charcoal, in order to accurately control the charcoal specifications, it is indispensable to use the rod machine propeller and sleeve, and the complete propeller punch and no precipitation The sleeve is a necessary condition for precision charcoal rod specifications. Therefore, we should check whether the propeller punch is defective and the inside of the sleeve is precipitated before the production of the rod maker.

4. Routine inspection of carbonized supporting facilities: Everyone knows that the carbonization process is the final condition that determines the quality of charcoal products. The condition for determining the quality of carbonization is the temperature control facility of the carbonization furnace, that is, the gasification furnace; we should Before the carbonization production, it is necessary to check whether the gasification furnace has gas breakage or gas leakage, and avoid the loss of control of the carbonization temperature.

High quality charcoal manufactured by charcoal machine equipment

High-quality finished carbon is expected by every user and manufacturer. We can judge the quality of charcoal by judging the color, shrinkage, hardness, crack and steel sound of charcoal. This is also the standard of high-temperature carbon and low-temperature carbon. One. As a user of Shuliy, how to judge the quality of charcoal made by small charcoal making machine equipment?

The higher the standard requirement, the longer the burning time of the kiln and the higher the furnace temperature requirement. The more serious the burning of charcoal will be, the lower the natural carbon removal rate will be. Many customers are familiar with the carbon quality of charcoal machine equipment, but the quality of the finished carbon is not accurate.

Using the senses to simply judge the quality of charcoal:

1. Charcoal length. Under normal circumstances, the length of charcoal packing should be more than 5cm.

2, carbon diameter (shrinkage), at present most domestic charcoal machine equipment manufacturers use 5cm diameter forming sleeve standard, so the finished carbon diameter should be below 4cm, with 3.5-3.8 as * shrink size.

3, charcoal color, if the charcoal is pure black from the outside, if the color is black, the knocking sound is not crisp, indicating that there is a wet water problem, the water content will exceed the standard. The charcoal can be broken to observe the color of the section. If there is yellowing, it means that there are too many carbon impurities, or the carbonization process is not standard.

Charcoal has a smell of smoke (charcoal taste does not necessarily have a smoke, but smoke must have a taste), and tasteful charcoal has a certain influence on industries such as food processing industry and mosquito coil production. This is the obvious phenomenon of incomplete carbonization.

When the carbon rod is carbonized, when the kiln temperature reaches a certain level, a hard carbon film is formed on the surface of the charcoal and the inner hole. This black hard film will thicken as the kiln temperature increases. Observe this layer. The film can naturally see the charring heat of the charcoal. High-temperature charcoal and low-temperature charcoal are also easily judged.

4, hardness, holding the carbon rod with one hand upright, the thumb can not easily break the standard. The better the hardness, the better the quality of the charcoal.

5, steel tone, two pieces of charcoal hit the building, can send a crisp metal tone

6, cracks, charcoal allowed a small amount of cracks, does not affect the quality of charcoal. However, the crack is too large, indicating that the density of the semi-finished wood stick is not good or the oxygen supply during the carbonization process is too large, so that the crack cannot be completely shrunk.

It is important to produce high quality charcoal to purchase good quality equipment. It is also important to master the carbon making skills. The investment in charcoal machines is low, and the benefits are fast. This is the fact that the demand for charcoal is increasing and profits will continue to heat up.

Small smokeless charcoal machine

The quality of machine-made charcoal produced by small smokeless charcoal making machine equipment is related to the sales volume and economic benefits of the manufacturer. Each charcoal making machine manufacturer cares about the quality of machine-made charcoal, but in actual operation, the finished product The quality of charcoal will be affected by various factors, the main ones are the influence of process and raw materials. What is the quality of the finished carbon of the specific small smokeless charcoal making machine?

1. Charcoal is a water-increasing substance, and the water content during normal storage is generally below 7%. The degree of moisture absorption is affected by the relative humidity in the air and the degree of oxidation of the surface of the charcoal. The water absorption capacity of charcoal when it comes into contact with water depends on its structural characteristics and surface infiltration, and it can absorb moisture beyond its own weight.

2. The content and composition of ash are affected by the type of wood, carbonization process, and harvesting and transportation. The content is generally within 6%.

3. When charcoal is heated above the pyrolysis temperature, volatile gases are decomposed. The carbon remaining after a few minutes of calcination at a high temperature (850 ° C to 950 ° C) is called fixed carbon, and when it is used under high-temperature conditions, it is no longer volatilized and can participate in the reaction. It is the main ingredient in charcoal.

4. The true specific gravity of charcoal is mainly related to the calcination temperature, and has little relationship with tree species, generally between 1.3 and 1.4; the apparent specific gravity is generally between 0.2 and 0.5, which varies not only by tree species but also by porosity. Generally, the pores of charcoal account for more than 7% of the volume of charcoal and are affected by tree species, growth sites, and carbonization processes.

5. The specific heat capacity of charcoal production machine charcoal depends on the heating temperature and the quality of charcoal and increases with the increase of temperature. The calorific value depends on the carbonization conditions, generally around 33.5 MJ. The higher the carbonization temperature, the greater the heat generation.

7. Since all aspects of wood structure are different due to heat shrinkage, charcoal will cause cracks and affect the strength. The compressive strength of charcoal along the longitudinal direction of the fiber is close to or even reaches the strength of coke, while the compressive strength along the transverse direction of the fiber is only 1/4 to l/6 of coke. In addition, the low wear strength of charcoal also affects its use.

8. The specific resistance of charcoal is quite large, about 1010 to 1012 Ω·cm. The direction of the fiber is only 1/3 to 1/5 of the vertical direction.

9. A large number of micropores and transition pores present in charcoal make it not only have a high specific surface area, but also have good adsorption properties after the tar substance in the pores is removed, so it is an important raw material for the preparation of activated carbon.

Small sawdust charcoal machine production line

In the small sawdust charcoal machine production line, in the process of operation and operation, some troubles will inevitably occur, which is a headache for new users, which not only affects the normal production operation but also causes the equipment for a long time. The damage, for the failure in the charcoal machine production line, shuliy machinery made the following solutions.

1. Motor heating degree: The motor is hot, and the back of the motor is in contact with the motor casing. If the hot hand indicates that the motor may be out of order, stop the car immediately, first remove the V-belt, and test the motor. If the motor starts normally, the current and voltage insulation meet the requirements. The main part should be inspected again to see if the charcoal molding machine is faulty. If there is no fault, the raw material is too dry, causing excessive load.

2. The impeller performs a simple dynamic balance test. The test method: after the impeller is lifted, the hand is toggled to make it gently rotate, and the place where the balance is not reached will swing left and right. If it is biased, it can be spot welded on the opposite impeller, increase the weight to balance, or use the angle grinder to grind away the weld marks of the heavy impeller, and the balance can be achieved, so that the fan of the charcoal powder molding machine can be repaired for normal work. It is. Note that in the repair process of the fan, it is not possible to use the spot welding of the electric welding to leave the welding mark on the impeller so as not to affect the balance of the fan impeller, and the repairing purpose is not achieved, resulting in greater loss.

    In the case where the rivet hole is prone to fatigue cracking, it is possible to weld the crack with a new unused electrode, but it should be symmetrically centered on the impeller axis, leaving the remaining electrode of the crack at the crack. Then, a new welding rod is used to repair the rivet hole crack of the symmetry. After the welding, the remaining welding rod is as long as the remaining welding rod when the symmetrical rivet is repaired, so as to ensure the equal weight of the welding repair. If there is no crack at the symmetrical rivet hole, the electrode should be welded here to offset the newly added welding weight at the symmetry rivet hole crack.

3, the shifting movement is unbalanced: the main performance is when the punch is 10-15mm above the turntable; the turntable keeps turning, or the punch goes up to the top of the turntable 10-15mm, the turntable starts to turn, the more serious is the punch When the turntable is turned (either up or down), the turntable is rotating, causing unimaginable consequences. This phenomenon is called time is wrong and generally does not appear.

4. There are many reasons for punching charcoal powder:

A. The carbon powder has strong adhesion and the charcoal block is too hard.

B. The moisture and raw materials of the charcoal powder are too dry, and the pressed charcoal block is relatively harder than usual. During the pressing process, the resistance of the punching needle is increased. If it is not removed from the charcoal block, it is easy to cause sticky charcoal powder or The charcoal block is divided into two sections.

C. The spring is too loose, broken or loses its effectiveness. The needle is not strong enough, and the needle cannot be recovered, causing sticky charcoal powder. If the spring is too loose, adjust the pressure adjustment disc and replace it if it breaks or fails.

D. There is a hard object in the charcoal powder to make the punch deformation, and the movable plate does not come under, which causes the sticky charcoal powder. Need to remove the punch to replace the new needle.

E. The needle is finely ground and has a large taper. When the charcoal powder is too fine and the viscosity is high, the charcoal powder easily adheres.

F. The sliding parts of the punch should be lubricated with lubricating oil.

Small industrial dryer equipment

Scope of industrial dryers: Rotary dryers are widely used in food, feed, chemical, pharmaceutical, mining, and other industries. The working process of the equipment is as follows: after the dehydrated wet material is added to the dryer, the material is uniformly dispersed in the dryer and fully contacted with the hot air in the dryer, and the heat transfer and mass transfer are accelerated.

In the drying process, the material is discharged under the action of the inclined plate and the hot temper, and the star discharge valve is discharged to the other part of the dryer. The machine is suitable for drying various types of slag materials with water content less than 85%, such as beer waste, bean dregs, sprayed corn husk, coal slime, pomace, etc., which is good for opening up feed resources, reducing feeding cost and reducing environmental pollution. effect.

The heat source of the industrial dryer comes from the combustion device, and the dryer adopts a downstream heating method. Therefore, the material to be dried is slipped from the feed box and the feed into the cylinder, that is, pushed back by the spiral copy board. As the dryer is placed obliquely, the material flows to the rear end under the action of gravity and rotation. On the other hand, the material is repeatedly picked up by the copying board, and is taken to the upper end and then continuously sown down, so that the material forms a uniform curtain in the cylinder. The curtain is fully exchanged with the hot air flow in the cylinder. As the material is repeatedly spread, the moisture contained is gradually dried, thereby achieving the purpose of drying.

1. The same shape of the lifting plate is staggered and installed; secondly, the combined type of lifting plate is adapted to promote the drying material to form a complete curtain on the drying simplified cross section under the action of different orientations and different lifting plates, thereby improving Heat transfer effect, reducing heat loss.

2. Add a high-efficiency crusher to further break the drying material, and promote the specific surface area of the dryer to increase by 2-3 times. Therefore, in the case of the same thermal energy, the thermal efficiency is increased by 2-3 times due to the increase in the area of heat exchange between the material and the hot air.

3. Change to a speed control motor. The operator can freely adjust the speed of the dryer according to the initial moisture level of the dryer in the speed range of 2~8r/min. The final moisture of the drying material meets the quality requirements and saves energy.

4, the old-fashioned dryer roller directly contacts the outside air, so that a lot of heat is dissipated. The dryer manufacturer adopts the insulation method of wrapping the cylinder with asbestos, so as to avoid unnecessary waste of heat. The practice has proved that this measure can save 15% of thermal energy.

Rotary dryer equipment drying materials

The small rotary dryer equipment is to make full use of the wood waste residue from the wood processing. These things are worthless to ordinary people, but the sawdust dryer can transform these inconspicuous things into raw Material fuel or wood product base material.

The use of small rotary dryer equipment is simple and can be used by both self-employed and enterprises. Rotary drying is also a good entrepreneurial project, which can not only increase the income of farmers but also reduce the pollution of the environment to a certain extent. The small rotary dryer equipment has reasonable planning, high output, low failure rate, and easy operation and protection.

1. The combination of material and moisture is the factor for determining the difficulty of boring. Together, it also determines the energy consumption level and the length of time spent in the interior of the small rotary dryer equipment. This situation is related to small rotary drying. The selection of machine equipment is inseparable. For example, for some materials that are not easy to be boring, it is mainly necessary to give a longer staying time instead of strengthening the external boring conditions.

2, the shape of the material, the material can exist in a variety of shapes, such as large-scale molded wood, ceramic products or other sheet-like, fiber pile, granular, or even liquid materials, these can As a boring material in the industry, the selection of small rotary dryer equipment should also be considered according to the shape of the material.

3, the material itself has some physical characteristics, the physical properties of the material itself generally have density, bulk density, hot melt, and the adhesion of the material, etc., can be the adhesion of the bump, it is small rotary The operation of the dryer equipment has a direct impact, and when the adhesion is severe, the boring process cannot be carried out.

4, the demand to pay attention to the material in the boring process of some matters, these factors mainly have the heat sensitivity of the heat of time, some materials will change some changes when heated, such as discoloration, decomposition and transformation, etc., other materials in the boring process due to Shortening will cause the material to deform or crack, and then the quality of the material will be reduced or even invalidated.
