Belt conveyor roller spray device

The raw coal produced in the coal industry is generally transported by belt conveyors, which are characterized by stable operation, large carrying capacity, low maintenance costs in the later stage of operation, and easy automation and centralized control, so they are widely used in the coal industry.

The roller plays the role of transmission and direction change in the belt conveyor, and is an important part of the conveyor. The drum can be divided into two driving modes: external drive and internal drive, and the shape can be divided into drum drum, blade drum and groove rubber surface drum.
In low temperature and severe cold areas, due to the influence of climate and conveying materials, the surface of the reversing roller will freeze during the operation of the belt conveyor, resulting in a decrease in the friction force of the belt and the inconsistency of the circumference. Shifts need to be corrected for 1 or 2 times, each time affecting production for about 20 minutes.
1. Technical solutions
Through problem analysis, the method of spraying antifreeze at fixed points and timing of the drum can effectively solve the problem of drum freezing, reduce equipment failure rate and improve equipment production efficiency.
2. Device production
Use φ15 galvanized steel pipe to make pipelines, and make branch pipelines at the diverting drum on each layer. The branch pipelines are installed in parallel and 400mm above the diverting drum. Each parallel pipeline is provided with 4 atomizing nozzles. Equipped with solenoid valve multi-point control, relying on a self-priming pump to boost pressure to form an antifreeze spray device.
3. Application effects
After the application of the roller spraying device of the belt conveyor, by spraying the antifreeze on the surface of the roller, the freezing phenomenon of the roller can be slowed down and the occurrence of equipment failures can be reduced. 1 to 2 times a week to achieve good application effect and ensure effective production time.
The roller spraying device is suitable for low temperature and severe cold areas, and can be popularized and applied in enterprises using belt conveyors in similar climatic environments.
