In mining production, belt conveyors are widely adopted for mineral transportation. Characterized by stable operation, large carrying capacity, low maintenance costs, and easy realization of automation and centralized control. They are especially prevalent in the coal industry.
The belt conveyor drums play a crucial role in the belt conveyor system, responsible for transmission and direction change. Drums can be classified into two driving methods: external drive and internal drive. In terms of appearance, they are divided into drum-type drums, vane-type drums, and grooved rubber-faced drums.
Impact of Drum Freezing
In extremely cold regions, due to the climate and the nature of the conveyed materials, ice forms on the surface of the deflection drums during the operation of belt conveyors. This leads to a decline in the friction force of the conveyor belt and inconsistent circumferences. As a result, the conveyor belt frequently deviates during production. Workers need to correct the deviation 1-2times per shift, with each correction taking about 20 minutes and affecting production accordingly.
Anti-freezing Solution for Belt Conveyor Drums
After a detailed problem analysis, a method of spraying antifreeze at fixed points and fixed times on the drums has been adopted. This effectively addresses the issue of drum icing, reduces equipment failure rates, and boosts production efficiency.
Anti-freezing Device for Belt Conveyor Drums
The device is constructed with P15 galvanized steel pipes for the main pipeline. At each layer of the deflection drums, branch pipelines are installed. These branch pipelines are mounted parallel to and 400 mm above the deflection drums. Each parallel pipeline is equipped with four atomizing nozzles, and each branch is outfitted with multiple solenoid valves for precise control. A self-priming pump is used for pressure boost, forming a complete antifreeze sprinkler device.
Anti-freezing Effect on Belt Conveyor Drums
Since the application of the conveyor belt drum sprinkler device, spraying antifreeze on the drum surface has significantly alleviated the drum icing problem. Equipment failures have been reduced, and the frequency of conveyor belt deviation has dropped remarkably, from 1 – 2 times per shift to 1 – 2 times per week. This has achieved excellent application results and ensured effective production time.
The drum sprinkler device of the belt conveyor is suitable for extremely cold regions.
