The inside of the dust and gas treatment box is also provided with the first-level filter layer and the second-level filter layer. The lower end of the box is also provided with the sludge outlet and the water outlet, the sludge outlet is arranged directly above the sludge conveyor belt, and one end of the sludge conveyor belt is provided with the sludge collection box, The sludge conveyor belt is driven by the pulley, the sludge outlet is connected to one end of the water purifier, and the other end of the water purifier is connected to the water pump.

Further, as a preference, there are multiple fans and suction hoods arranged side by side.

Further, preferably, a plurality of the high-pressure nozzles are arranged side by side at the inner top of the dust and gas treatment box.

Further, preferably, the number of the high-pressure nozzles is at least six.

Further, preferably, the height of the sludge outlet is lower than that of the water outlet.

The beneficial effects of the utility model:

The coal mine dust removal device provided by the utility model has a simple structure and is easy to use. When in use, the spraying and dust removal effects can be significantly improved through the high-pressure nozzle, and the water can be recycled through the water purifier, which improves the utilization rate.
