A coal mine gas drainage pipeline water discharge device

Abstract

The invention relates to a water draining device of a coal mine gas drainage pipeline. The water draining device is used for realizing drainage of water accumulated in the pipeline in the process of gas drainage and comprises a water incoming device, a water storing device and a water draining device body, the water incoming device comprises a gas delivery rubber pipe, the water storing device comprises a water collection pipeline and a water incoming funnel, the water draining device body comprises a water storing pipe and a water draining funnel, a supporting strip, a floating ball, a tension spring and a rubber sealing pad are arranged in the water storing pipe, and a round rubber sheet is fixed at the lower end of the water draining funnel. By the water draining device, the problem that water draining devices are poor in water draining effect, have water draining ports prone to being blocked by coal residue, have complex water draining structures and are invisible and high in cost in the prior art is solved, automatic water draining of the gas drainage pipeline is realized safely, efficiently and stably, the water accumulation problem of the gas drainage pipeline is solved, and safe production is guaranteed.

Description

technical field [0001] The invention relates to a water discharge device for a coal mine gas drainage pipeline, which is used for realizing the discharge of accumulated water in the pipeline during the gas drainage process, in particular to a coal mine gas drainage pipeline water discharge device. Background technique [0002] In the process of underground gas drainage in coal mines, it is easy to have different degrees of accumulated water in the gas drainage pipeline, and the accumulated water is accompanied by coal slag, which will easily affect the gas drainage effect. With the accumulation of coal dust in the gas drainage pipeline , It is easy to cause a burden on the gas drainage pipeline. Therefore, it is necessary to frequently discharge water to the gas drainage pipeline. At present, the water release devices used in coal mine gas drainage pipelines mainly include automatic water discharge devices for floating water storage tanks and manual water discharge devices....
