Technical Field

The invention relates to the technical field of bulk material conveying, in particular to a dust cleaning device for a closed corridor of a suspension type belt conveyor.

Background

At present, belt conveyors are widely used for conveying bulk materials such as grains, cement, coal and the like. With the increasing strictness of the environmental protection requirement, the corridor of the belt conveyor needs to be closed, and the dust treatment in the closed corridor is difficult. During the working process of the belt conveyor, part of bulk materials are bound on the belt surface of the belt conveyor and are scattered on the ground of the gallery during return stroke, so that ground accumulated materials are formed. The conventional cleaning method is to arrange two cleaners on the belt conveyor for scraping off the residual materials on the surface of the return belt and performing centralized treatment near the head of the belt conveyor. In recent years, various cleaners for different materials have been developed in the market. However, due to the change of the operation condition of the belt conveyor, the aging of the sweeper and the change of the moisture and the granularity of the material, the sweeping effect of the sweeper is poor, the accumulated material with different degrees still exists below the belt conveyor, and the accumulated material needs to be cleaned manually and continuously. The manual cleaning requires workers to clean the floor of the gallery below the belt conveyor without stopping the belt conveyor, and is dangerous. At present, no mature technology for automatically cleaning the closed gallery of the belt conveyor exists. Therefore, how to rapidly and efficiently solve the problem of dust deposition of the closed corridor of the belt conveyor is a technical problem to be solved urgently.
