Description

Technical Field

[0001] The utility model belongs to the field of sludge cleaning, and particularly relates to a sludge cleaning device in a coal mine sump. Background Technique

[0002] The coal mine sump is an indispensable facility in coal mine safety and production, mainly used for storing and treating the inflow water in the mine. It is usually set at the bottom or low-lying area of the mine. The sump guides the inflow water into the tank through the drainage system. After sedimentation and filtration, etc., equipment such as drainage pumps is used to discharge the treated water out of the mine.

[0003] However, there are usually a large amount of sediment impurities in the coal mine inflow water. After sedimentation treatment, they will accumulate at the bottom of the sump, thus affecting subsequent use. The existing sludge cleaning devices usually use scrapers to scrape the sludge from the inner wall of the sump and then discharge it. However, the sludge is relatively viscous, the discharge speed is slow, and it may also block the sewage pipe or sewage outlet. Summary of the Utility Model
