Belt conveyor anti-roller clamping device

Our company is a professional wharf for ore loading and unloading operations, and the annual unloading of various types of iron ore reaches more than 35 million tons. The company's mechanical equipment mainly includes three major parts: ship loader and unloader, bucket wheel stacker and reclaimer, and belt conveyor. The belt conveyor is more than 34,000 meters long, which is the link between the ore entering and leaving the port area, and runs through every part of the entire port area. corner.

With the rapid development of the company, the requirements for ore throughput and freight quality continue to increase, the number of minerals to be transported continues to increase, and the conveyor belt conveyor is increasingly heavy. When the belt conveyor is transporting minerals with high viscosity and high humidity, the belting and blanking conditions on the return surface are aggravated. When the material is brought to the drum, it will cause the material between the drum and the belt, which will affect the normal operation of the equipment.

In order to reduce the harm to the belt conveyor caused by the roller clamping, we have made a set of anti-roller clamping device (see Figure 1), which is installed at the tail roller of our company's BC2 belt conveyor. It was converted from a discarded sweeper. There is a small gap between the polyurethane scraper of the cleaner and the belt at the drum. When the material is clamped at the drum, the belt will bulge, and the belt will collide with the scraper of the cleaner, so that the cleaner has a small angle. Turning, at this time, the contacts fixed on the cleaner are in contact with the contacts of the protection switch installed at the back, so that the protection switch is activated, and the signal of the switch is connected to the operation process signal. After the switch is activated, the process stops immediately, and the cleaning personnel clean up the material clamped at the drum before restarting the process. This device can timely find the clamped material or foreign matter at the drum, so that it can be dealt with in time, which can greatly reduce the hidden danger of accidents.

After the BC2 belt conveyor is installed with the anti-roller clamping device, the accident rate of the drum clamping is greatly reduced, and the belt is well protected.
