Conveyor belt or conveyor drum

 

1. In order to ensure the necessary starting energy moment, the current of the electric idea is 6-7 times larger than that of the rated operation. To ensure that the electric idea will not be burned due to the impact of the current, and the power grid will not excessively reduce the voltage due to the large current, it is required that the starting process of the electric idea should be as fast as possible, and the acceleration of the rotor should be increased. In order to make the launching process within 3-5 seconds, we used to increase the power of the electric power in the early years, which may be helpful for small and short belt conveyors.

 

2. Conveyor belt is a kind of viscoelastic body. In the weak stage of large belt conveyor, the traction force and inertia force exerted by the driving equipment on the conveyor belt will be transmitted, superimposed and reflected in the belt at a certain wave speed. Combined with the influence of other factors, it will cause variable stress changes in the conveyor belt. If the instantaneous peak stress exceeds the allowable value, the conveyor belt will be damaged or even damaged The cracking, or the roller, drum damage, which requires as little as possible to initiate acceleration when the impact of the lower launch.

 

Analysis and treatment of conveyor drum blocking

 

There are many reasons for the roller of the conveyor to be blocked. At the beginning, let's talk about the methods to avoid the blocking: strictly implement the operating procedures, start without load and park without load; ensure the uniform feeding. Just choose the various technical parameters of the conveyor drum, assuming that the speed of the slow conveyor drum can not be too large. It is necessary to increase the discharge port or lengthen the end of the chute to deal with the problem of poor discharge and no time to discharge, so as to avoid end blockage. An anti blocking valve is arranged on the cover plate of the discharging end. Because of the deposition of materials, the anti blocking door should be opened, and the materials entering the conveyor should be cleaned to avoid the blockage caused by large impurities or fibrous impurities entering the conveyor. It is necessary to reduce the lateral dimension of the surrounding suspension bearing as much as possible to reduce the possibility of blocking when the material passes through the surrounding bearing. When the level device of the equipment bin and the blockage sensor are connected, the active operation and alarm shall be completed. In the use of conveyor belt drum, the phenomenon of blockage will be greatly reduced or even will not occur, so the production and use of unimpeded.
