Water drainage device for mine gas extraction pipe

Abstract

The invention relates to a drainage device for a mine gas extraction pipe. The drainage device comprises a plurality of supporting assemblies, a drainage device body, a filter box, a filter screen, a motor, a rotating shaft, a first cleaning brush and a water inlet pipeline. The water inlet pipeline is communicated with the gas extraction pipeline, water in the gas extraction pipeline enters the filter box through the water inlet pipe, the filter screen can filter solid impurities in the water, and the water enters the water drainer body after being filtered by the filter screen and then is discharged from the water drainer body. The rotating shaft can be driven to rotate by starting the motor, and the rotating shaft drives the first cleaning brush to rotate, so that the first cleaning brush rotates along the surface of the filter screen, impurities attached to the surface of the filter screen can be removed, the filter screen is prevented from being blocked, and water flowing in from the gas drainage pipeline can be filtered; the water discharging device body is prevented from being blocked.

Description

technical field [0001] The invention relates to the technical field of drainage, in particular to a drainer for mine gas drainage pipes. Background technique [0002] During the mine gas drainage operation, the underground gas drainage pipelines are densely distributed, and solid impurities such as coal and soil or water are often produced in the drainage pipelines. The gas drainage process contains some water, and when the water flow accumulates in the gas pipes , affecting the effect of gas drainage, so it is necessary to use the gas drainage pipe drainer to drain water. After the gas drainage pipe is connected to the drainer, the water enters the drainer and is discharged. However, due to the large amount of impurities in the water, the existing The water drainer cannot filter the water, which will easily lead to the blockage of the drainer, which will affect the normal drainage. Contents of the invention [0003] The object of the present invention is to provide a min...
