Abstract
The invention relates to a hole packer for drawing out methane and grouting. The hole packer is characterized in that an inner tube wall is arranged on an inner wall of a methane-drawing tube, wherein the inner tube wall and the methane-drawing tube have an integrated structure; an inner tube cavity is formed between the inner tube wall and the methane-drawing tube; the inner tube wall and the methane-drawing tube are both made of anti-flaming antistatic plastic materials; a slurry outlet is formed in a middle tube wall of the methane-drawing tube; the slurry outlet is communicated with the inner tube cavity; a circle of annular one-way valve is arranged in a position of the slurry outlet in the outside tube wall of the methane-drawing tube; thread tube heads are arranged at the two ends of the methane-drawing tube; two lug bosses are arranged on the outer walls on the two sides of the methane-drawing tube; slurry passing holes are formed in the positions of the lug bosses; the slurry passing holes are communicated with the inner tube cavity; bolts are arranged at two end ports of the inner tube cavity; the two end ports of the inner tube cavity are plugged by the bolts; the bolts and the inner tube wall are sealed through sealants. The hole packer for drawing out methane and grouting has the beneficial effects of light weight caused by the adoption of plastic materials, reduced cost, anti-flaming and antistatic property, use safety and good plugging effect.
Description
Technical field
The present invention relates to colliery industry, one draws out methane and grouting hole packer specifically, is applied to when drawing out methane the shutoff in gap, extraction hole, coal seam, colliery and grouting.
Background technology
Current coal and non-coal is that the usual effect of underground coal mine extraction coal-bed gas is bad, commonly use common hole packer shutoff now, or use hole sealing bag sealing of hole, though part plugging action can be played, but the drainage gas pipe of part hole packer is irony material, not only heavy, and because all extraneous factor irony pipes easily produce spark in use procedure, so just very easily cause the explosion accident of gas, use dangerous.Hole sealing bag sealing of hole then result of use is bad, and shutoff is not tight, and extracting result is bad.
Summary of the invention
Technical problem to be solved by this invention overcomes the deficiencies in the prior art, one is provided to draw out methane and grouting hole packer, the technical solution adopted for the present invention to solve the technical problems is: structure of the present invention comprises drainage gas pipe, inner tubal wall, interior pipe cavity, annular one way valve, slurry outlet, enter slurry outlet, screw thread tube head, bolt, fluid sealant, boss, the inwall that it is characterized in that drainage gas pipe is provided with inner tubal wall, inner tubal wall and drainage gas pipe are integral type structure, pipe cavity in being formed between inner tubal wall and drainage gas pipe, the material of drainage gas pipe and inner tubal wall is fire retardant antistatic plastic material and makes, the middle tube wall of drainage gas pipe is provided with slurry outlet, slurry outlet communicates with interior pipe cavity, on the outside tube wall of drainage gas pipe, the position of slurry outlet is provided with a ring shape one way valve, the two ends of drainage gas pipe are all provided with screw thread tube head, the both sides outer wall of drainage gas pipe is also provided with two boss, be provided with into slurry outlet in the position of boss, enter slurry outlet to be connected with interior pipe cavity, the port, two ends of interior pipe cavity is all provided with bolt, the two ends port of interior pipe cavity is by bolt shutoff, sealant sealing is passed through between bolt and inner tubal wall.
The present invention adopts made of plastic, compound rubber Dilated rubber hose and safety valve use, two boss on drainage gas pipe are for installing elbow, Jin Jiang one end, one end pulp, interior pipe cavity in drainage gas pipe is mainly used in slip casting, the sealing material injected flows out from the middle grout outlet that draws out methane, and for the rubber swelling sebific duct expanded outside drainage gas pipe, on drainage gas pipe, the effect of the annular one way valve at grout outlet place prevents slurry adverse current.
The invention has the beneficial effects as follows, the present invention adopts plastic material, and quality is light, cost-saving, and flame-retardant and anti-static, use safety, plugging effect are good.
