Description

Technical Field

[0001] The utility model relates to the technical field of belt cleaning equipment, in particular to a novel self-return cleaning device for belt bottom materials. Background Art

[0002] In the existing coal preparation plant, some belt conveyors often carry materials on the return belt due to the high water content of the materials, the influence of the moisture content of the coal and the ambient temperature, and the damage to the belt surface. This causes the materials to fall along the belt conveyor and a small amount of coal slime to stick to its bearing surface. The conveyor belt is wound differently on each roller. The bearing surface of the conveyor belt not only contacts the upper and lower rollers, but also contacts the tensioning roller. When the materials stick to the rollers and rollers, their diameters change, causing the conveyor belt to deviate, and the belt conveyor cannot work normally. When the materials are seriously carried, it may even need to be stopped for cleaning, which requires a lot of work for the employees and affects production.
