What are the consequences of the screw conveyor after the material is blocked

The rapid development of modern industry has promoted the progress of industry, the screw conveyor is an indispensable equipment in the conveying equipment, and the following problems of some conveying equipment caused by this make it unable to work normally, what measures can prevent the screw conveyor from plugging, and what are the consequences after blocking? How did this kind of incident not happen?

1.The screw conveyor is not easy to convey the winding material of the material;

2.Intermediate suspension bearings are easy to clog materials.

3.If the blockage is light, it will affect the output and increase the power consumption, 4In severe cases, it will burn out the motor, 5There is also the possibility of torsion of the helical shaft.

How can this kind of incident be prevented?

1.According to their own material parameters such as: length, conveying volume, specific gravity, mesh, fluidity to choose their own conveyor model.

2.The material with poor fluidity is increased to solve the problem of poor discharge or too late discharge.

3.A short section of anti-rotation blades is installed at the end of the discharge chute to prevent the end from plugging.

4.Avoid debris entering the machine and causing blockage.

5.Each no-load start and no-load stop to ensure continuous and uniform feeding.

6.If the material accumulation against the discharge port during the blockage, the power supply should be cut off as soon as possible.

7.Avoid the biggest accidents and cause more damage.

The screw conveyor is made of steel, and the screw conveyor is used to transport chemical and building materials products such as powder or solid particles with high temperature. The inside of the screw conveyor is a conveyor pipe, and the blades are welded to the conveyor pipe in a spiral shape. If you want to buy a screw conveyor, you can go to Zhengzhou Xinhai Machinery Factory to see, there are more spots.

The screw conveyor is suitable for horizontal or inclined conveying powder, granular and small block materials, such as coal mine, ash, slag, cement, grain, etc., and is not suitable for conveying perishable, viscous and agglomerated materials. The role in the concrete batching plant has been the greatest embodiment, the failure of the pan directly affects the efficiency of the entire production line, and the most common fault of the screw conveyor is the blockage. There are many reasons for blockage, and the following measures can be taken to prevent blockage:

Enlarge the discharge port or lengthen the end of the trough to solve the problem of poor discharge or too late discharge. At the same time, a small section of anti-rotation blade can also be installed at the end of the discharge port trough to prevent the end from plugging, such as the slow screw conveyor speed should not be too large. Strictly implement the operation procedures to achieve no-load start and no-load parking; Ensure continuous average feeding; Carry out the necessary cleaning of the materials entering the conveyor to prevent large impurities or fibrous impurities from entering the machine and causing blockage.

Install silo leveler and blockage sensor to achieve automatic control and alarm; An anti-blocking flap is set up on the cover plate of the discharge end. The transverse size of the intermediate hanging bearing is reduced as much as possible to reduce the possibility of material plugging when passing through the intermediate bearing.

During the use of the screw conveyor, the middle suspension bearing is easy to block the material, and the screw conveyor is very sensitive to the material, because the screw conveyor conveys the material space is small. Therefore, the blockage of the screw conveyor is the most common phenomenon in the work of the machine, if the blockage occurs, it will affect the normal use of the machine, increase the power consumption, and even may burn out the motor, the screw shaft will be broken, which will affect our normal work.

There are many reasons for the blockage of materials in the screw conveyor, and Parkson Machinery will give you an analysis of what are the measures to prevent blockage:

1.It is necessary to strictly implement the operating procedures, so that there is no load start and no-load parking; Ensure that the feeding is continuous and uniform.

2. The various technical parameters of the screw conveyor should be reasonably selected, and if it is a slow screw conveyor, the speed of the screw conveyor should not be too large.

3. It is necessary to increase the discharge port or lengthen the end of the trough to solve the problem of poor discharge and too late discharge. At the same time, a small section of anti-rotation blades can be installed at the end of the discharge chute to prevent material plugging at the end.

4. Set up an anti-blocking valve on the cover plate of the discharge end. If a blockage occurs, it is due to the accumulation of materials, open the anti-blockage door and cut off the power supply through the travel switch.

5. Necessary cleaning should be carried out on the materials entering the conveyor to prevent large impurities or fibrous impurities from entering the machine and causing blockage.

6. The transverse size of the intermediate suspension bearing should be reduced as much as possible to reduce the possibility of material blocking when the material passes through the intermediate bearing.

7. When installing the silo level device and the blockage sensor, it is necessary to realize automatic control and alarm.

Xinxiang Chuangjia Vibration Machinery Factory has a wide variety of screw conveyors, and our company's technicians will choose the right screw conveyor for you according to the technical requirements you give. Welcome users to inquire and buy!

1.The motor power is small, resulting in the screw conveyor not being able to supply materials.

2.The blade is resistant to the pitch problem, and the general blade should adopt a gradual dry fiber pitch, and the pitch strain from the feed port to the discharge port is large.

3.The elevation angle is too large, and 30 degrees is generally the best.

4.Pay attention to rainwater to avoid agglomeration, and clean and maintain regularly.
