Under what circumstances are mesh belt dryers prone to accidents

When the conveyor belt is running normally, the belt speed is not less than 95% of the roller speed. If the friction between the roller and the conveyor belt is not enough, the conveyor belt is prone to slippage. There are many reasons for the lack of friction between the roller and the conveyor belt

The tension is not enough, the load starts, the friction coefficient on the surface of the roller is not enough, etc.

If the tension of the mesh belt dryer is not enough, the reasons are: insufficient tension stroke, insufficient counterweight weight, too long conveyor belt, etc.; The reasons for the insufficient friction coefficient on the surface of the roller are: the rubber on the surface of the roller is too abrasional, the belt body is too wet or there is lubricating oil, and the surface of the belt body is glued with materials (easy to be soluble in water).

the cause of the mesh belt deviation accident; If there are frequent deviation accidents, the service life of the conveyor will be affected, and the serious case will cause the shutdown accident is very likely to cause the staff.

What energy source? Coal boilers and natural gas boilers are easy to do, they belong to special equipment, safety hazards, and open flames, which are easy to cause fires.

It is recommended to use air energy heat pump, non-special equipment, low failure rate, easy maintenance. There is no safety hazard of open flames.

Mesh belt dryer maintenance tips! The mesh belt dryer is a relatively complex equipment in the dryer products. The mesh belt dryer is mainly used in the production of 1 square meter and 3 square meters and other specifications, most of which adopt the mesh belt structure, and are separately equipped with a metal hot blast stove to provide hot air.

Details that should be paid attention to when operating the dryer equipment: 1. At the end of the dryer operation, please turn the temperature adjustment knob to 0 degrees to reduce improper start-up and prolong the service life of the solenoid valve. 2. The newly installed hoop of the dryer is easy to loosen and must be checked frequently 3. Before using it every day, it is necessary to check whether the filter screen is blocked, if the blocked air volume will be reduced, it will produce slow drying, drying can not dry, and waste energy.

4. The exhaust pipe and elbow must be cleaned once a month, if not cleaned, the drying time will be extended. 5. Butter must be added to the bearing seat of the dryer every month to ensure the lubrication of the bearing. Mesh belt dryer maintenance tips 1 When it is found that the drying net is damaged or seriously worn, the mesh belt should be repaired or replaced in time.

The method of replacing the drying net is: first remove the sprocket at the main transmission end of the layer of drying net, the operator faces the machine, unscrews the bolt on the end cover of the main and passive shaft ends of the layer of drying net on the left side of the machine, extracts the main and passive shaft components, opens the observation door, takes out the drying net chain out of the box, and when replacing it with a new drying net, pay attention to the tightening of the drying net and the supporting screen roller with stainless steel wire every interval of 6-8 supporting screen rollers, and then installs and debugs according to the above opposite steps. Note:

When adjusting the tension of the drying net chain with the distance adjustment seat at both ends of the passive shaft, the chain should not be too tight or too loose, and the tension of the left and right chains must be consistent. 2. Check whether the parts of the hot blast stove used with the dryer, such as the furnace, grille, chimney, inner wall and hot air pipe joints, are damaged, and if there is damage, they should be repaired or replaced in time. 3. The gearbox, bearing, and chain supporting the dryer should also be regularly maintained with other equipment.

Dryer bearing: The bearing is the most important part of the dryer. The full load of the dryer is basically borne by the bearing, and the quality of the lubricating oil can directly affect the service life and operation rate of the machine.

The bearing of the dryer has high requirements for the lubricating oil, the lubricating oil must be clean, and the seal must be good The main oil injection of the dryer bearing is the rotating bearing, roll bearing, all gears, movable bearings and sliding planes. Pay attention to whether all parts of the machine are working normally and check the degree of wear of the wear parts, and pay attention to the replacement of worn parts at any time. When putting the underframe plane of the movable device, the test machine of dust removal should be carried out in advance, so as to avoid the dryer being blocked, the drying can not run smoothly, and accidents are likely to occur!

1. It is equipped with an automatic tensioning device, and the mesh belt runs smoothly and turns over, so as to solve the phenomenon of chain dropping, chain jamming, and deviation.

2. The screen is made of heat-resistant steel wire woven into a mesh, which has high strength, is not easy to deform, and has good air permeability.

3. The mesh belt is driven by a speed-regulating motor, which can adjust the running speed and control the drying time according to the needs.

4. The digital display of the temperature of each section in the mesh belt dryer is convenient for grasping and controlling the temperature in the kiln.

5. There is a maintenance channel in each section of the mesh belt dryer, which is convenient for the maintenance of the equipment.

6. The hot blast furnace is the only one that adopts chain furnace automatic heating equipment, automatic coal loading, automatic slag removal, high thermal efficiency, wide adaptation to coal types, clean and environmental protection, labor and time saving.

7. Equipped with a fire prevention device, the kiln head, the kiln, the kiln tail, equipped with three thermocouples, the flue air inlet is equipped with a smoke gate, once the machinery fails, immediately put down the gate, isolate the heat source, and prevent **.

8. Positive pressure blowing is used to avoid the cooling breeze entering the cooling air due to the poor sealing of the section and the diameter of the section of the drying box, wasting the heat source, causing waste of heat energy and increasing the investment cost.

9. The design is to score from the upper low temperature zone and the tail low temperature zone to shoot the ball, and the briquettes are gradually heated by the low temperature zone and the high temperature zone, so as to avoid the briquettes containing 8-10% moisture after molding from cracking and bursting due to rapid heating, and the damage rate is low.

10. The air outlet temperature of the low temperature zone in the upper part of the drying box is 100, the dust content is small, the service life of the induced draft fan is long, and the operating cost is low.

The design, transformation and improvement of the mesh belt dryer designed by Henan Bailing has accumulated rich practical experience, and has been widely used in the metallurgical, chemical, coal, machinery and coking industries in Yunnan, Guizhou, Sichuan, Guangxi, Hunan, Hubei, Anhui, Jiangsu, Henan, Shandong, Shanxi, Hebei, Liaoning, Heilongjiang, Ningxia, Inner Mongolia and North Korea, India, Indonesia, Southeast Asia, South Africa and other countries, and has been unanimously recognized by users.

Zhengzhou Zhenping briquette equipment, the biggest advantage of the mesh belt dryer is that the drying effect is good, the heat source is diverse, the hot gas produced by coal can be used, and various types such as electric heating can also be used. The drying effect is very good. It has the advantages of fast drying, low crushing rate, energy saving and environmental protection, low cost, easy maintenance, and strong adjustability.

The length of the box can be extended according to the output.

1. When the invention drying net is damaged or worn out, the mesh belt should be repaired or replaced in real time.

The essentials of replacing the drying net are: first remove the sprocket at the main transmission end of the layer of the drying net, the operator faces the rigid board, unscrews the bolt on the end cover of the main and driving shaft ends of the layer of the drying net on the left side of the rigid board, extracts the main and driving shaft components, opens the inspection door, takes out the drying net chain out of the box, and replaces it with a new drying net, carefully cuts off 6-8 supporting screen rollers every 6-8 supporting screens with stainless steel wires to tighten the drying net and the supporting net rollers, and then places and debugs them according to the opposite pace mentioned above.

Meticulous: When adjusting the tension of the drying net chain with two real distance adjustment seats on the driving shaft, the chain should not be too tight or too loose, and the tension of the left and right chains must be equal.

2. Check whether there is any damage to the parts of the hot blast stove used with the dryer, such as the furnace, grille, chimney, inner wall and hot air pipeline, etc., if there is damage, it should be repaired or replaced in real time.

3. The accelerator box, bearing, and chain supporting the dryer should also be regularly maintained with other equipment and furnishings.

Dryer bearing: The bearing is the most tense part of the dryer. The full load of the dryer is simply borne by the shaft, which is smooth and oily.

The advantages and disadvantages can indirectly affect the service life and operation rate of the rigid. The bearing of the dryer has high requirements for smooth oil, which must be clean and well-sealed.

The important oil injection parts of dryer bearings are rotating bearings, roll bearings, all gears, motion bearings and sliding three-dimensional. Whether the things of each part of the meticulous and rigid parts can be normal and check the wear level of the wearable parts, it is necessary to carefully replace the worn parts at any time.

When the chassis installed in motion is three-dimensional, the test machine of dust removal should be held in advance, so as not to cause the dryer to be infarcted, boring and not able to run smoothly, and it is likely that the production and trade will become chaotic.
