Description

Technical Field

[0001] The utility model relates to the technical field of coal mine gas extraction, in particular to a slag discharge and water discharge structure of a gas extraction pipeline. Background Art

[0002] During coal mining, the gas in the coal seam must first be extracted to ensure the safety of mining work and avoid gas explosion accidents. During the extraction process, gas is often accompanied by coal slag and accumulated water, which makes the extraction pipeline narrower and reduces the efficiency of gas extraction. Waterproof slag discharge devices are widely used in gas extraction pipelines to filter coal slag and accumulated water in gas. However, the existing water discharge and slag discharge device for gas extraction pipelines cannot effectively collect coal slag and accumulated water when waterproofing and discharging gas, which makes it inconvenient to handle coal slag and accumulated water, resulting in reduced work efficiency.

[0003] The existing publication number is: CN218862665U. A gas extraction pipeline water discharge and slag removal device includes a box body, the left wall of the box body is fixedly connected with an air inlet pipe, and the right end of the air inlet pipe is connected to the interior of the box body, the right wall of the box body is fixedly connected with an air outlet pipe, and the left end of the air outlet pipe is connected to the interior of the box body, a support plate is arranged in the box body, and a slider is fixedly connected to the top of the support plate through a connecting rod, and a slide groove matching the slider is opened on the top of the inner cavity of the box body, and a plurality of uniformly distributed filter screens are fixedly connected to the bottom of the support plate. In general, the filter screen structure is arranged in a relatively simple manner, covering It is not comprehensive enough, so it cannot guarantee full and comprehensive filtering of the coal slag. Some coal slag will follow the gas and pass under the filter, and the filtering work cannot be completed, resulting in low filtration efficiency. Secondly, the filtering structure is shaken by reciprocating lateral movement, thereby shaking and cleaning the coal slag filtered out of the filter. The coal slag will become sticky after being mixed with water vapor. After being filtered out by the filter, it is easy to adhere to the filter. The filter cannot be cleaned by relying solely on lateral movement and shaking. The structural cleaning efficiency is not high, and the adequacy of the filter cleaning cannot be guaranteed, which easily affects the working efficiency of the filter. Utility Model Content
