Hydraulic punching coal-water-gas separator

Abstract

The invention discloses a hydraulic punching coal-water-gas separator, and relates to the technical field of mine safety. The hydraulic punching coal-water-gas separator comprises a separation barrel,wherein a separation barrel cover is mounted at the top of the separation barrel; a water-slag gas inlet and a gas outlet are formed in the two sides of the upper surface of the separation barrel cover respectively; a water-slag separation sieve is obliquely mounted at the upper side in the separation barrel; the left side of the water-slag separation sieve is higher than the right side of the water-slag separation sieve; a slag discharging opening is formed above the right side of the water-slag separation sieve; a water-slag filtering screen is mounted below the water-slag separation sieve;a cutting hole is formed above the left side of the water-slag filtering screen; a water discharging hole is formed in the bottom of one side of the separation barrel; a first hammer block is arranged below the water-slag separation sieve; a second hammer block is arranged below the water-slag filtering screen; and a driving system drives the first hammer block and the second hammer block to hammer and vibrate the water-slag separation sieve and the water-slag filtering screen respectively. The hydraulic punching coal-water-gas separator can be used for separating, discharging and collectingmixtures including gas, water, coal slag and the like, so that the problem that the gas exceeds the limit, caused by a spraying hole, is effectively avoided, and a space environment of a drilling field is also improved.

Description

technical field [0001] The invention relates to the technical field of mine safety, in particular to a hydraulic punching coal-water gas separator. Background technique [0002] With the continuous increase of mine mining depth, coal and gas outbursts are becoming more and more serious. In order to solve related problems, the best way at this stage is to use hydraulic punching technology. The high-pressure water impacts the coal body around the drilling hole through the high-efficiency nozzle, rushing out a large amount of coal body and gas, and the stress concentration moves to the surrounding of the punching hole, which relieves the pressure of the coal body near the drilling hole and increases the permeability, effectively improving the drainage effect. [0003] In the prior art, the key points of the anti-conflict measures are firstly to pump out a large amount of gas between and after punching holes; secondly, to be able to flush out a considerable amount of coal to for...
