Description

A device for cleaning sludge in coal mine water bunkers

Technical field

The invention relates to the technical field of coal mine water tank desilting, and in particular to a device for cleaning silt in a coal mine water tank.

Background technique

Coal mine underground water silos are selected near the bottom of the mine, near the bottom of the mine mining level, in the central area of the mine or near the central pump room. Some coal mines will also arrange mining area water silos in the mining area. Water inflow from various mining areas and equipment water in underground coal mines must be diverted through tunnel ditches, and finally collected into the central water warehouse. The mine water is discharged to the surface through the high-power high-pressure pump in the central pump room to maintain the normal operation of the mine and ensure the safety of the mine. Mining.

The mineral water produced during the coal mine production process contains a large number of impurities, mainly coal slime and sand, which precipitate at the bottom of the water tank, reducing the effective volume of the water tank. If the siltation is not cleared in time, the water tank will not only fail to function as a buffer and storage, but may also cause a well flooding accident; impurities in the incoming water will also enter the suction well of the main pump room, causing increased wear and tear on the flow-passing parts of the water pump and accelerating the failure of the water pump. Damage; when there is too much silt in the suction well, it will also block the suction faucet, making drainage difficult or impossible, seriously threatening the safety of the mine. Most of the existing water tank silt cleaning work uses multiple mud pumps to pump mud at the same time, but when one mud pump The pump has a limited range of action, poor silt removal effect, and will pump out water together, requiring subsequent mud-water separation work, which is costly.

In order to solve the above problems, we proposed a device for cleaning sludge in coal mine water bunkers.
