Abstract
The utility model discloses a spring tube gas-dust-removal hole sealing device which comprises a straight tubular cavity body, a pressure adjusting spring and a residue drainage pipe, wherein the pressure adjusting spring is coaxially in butt joint with the straight tubular cavity body, and the residue drainage pipe is connected to the side wall of the straight tubular cavity body. The spring tube gas-dust-removal hole sealing device has the advantages that when a drill stem drills to a coal layer, a drill hole is blocked by a gas dust collector, and especially after outer water pressure or air pressure is added, the gas dust collector expands in the radial direction to further keep the leakproofness of the work space of the drill stem, therefore, waste residues produced in the working process of the drill stem and the gas in the coal layer are collected and form a full mixture of water, gas and residues under the condition that a large amount of dustproof water is injected externally, and then the mixture is drained through the residue drainage pipe.
Description
Technical field
The utility model belongs to the technology field, particularly the waste residues such as pressure wind row powder boring mud of ejection in boring in the extraction borehole work progress dirt that goes out is processed, and prevents from executing getting out the harm of transfiniting of existing dust, and the site work environment of brill is executed in optimization.
Background technology
Coal mine gas, dust accident are one of disasters of down-hole, if gas, dust accident occur, not only can the heavy damage production environment, and can cause casualties, cause huge loss for the people, enterprise, country, therefore, eliminating gas exceeding limit and dust is the precondition of prevention gas, dust accident, is also one of important leverage of mine safety production.
Due to the geologic sedimentation effect, a large amount of toxic and harmfuls such as gas have been overstock in coal seam, in order to realize safe digging, generally, at first to arrange special-purpose gas pumping tunnel before digging, adopt underground drill rig construction extraction borehole to implement in advance gas pumping, after extraction is up to standard, can start digging coal.Yet in construction extraction borehole process, after particularly many mines enter deep horizontal, coal seam gas-bearing capacity, pressure all will increase, can be ejected into construction space because executing the refuses such as the gas dust that produces in the brill process and boring mud, the working environment of severe exacerbation construction, further,, if dust exceeds standard in a large number and gas produces the danger of exploding, cause more serious loss.
But, in the prior art,, for the Special drill place gas of these serious problems go out dirt and dedusting and sealing of hole integrated apparatus, therefore do not execute a large amount of gas dusts, boring mud in the brill process and can be released in tunnel, cause the potential safety hazards such as serious gas exceeding limit and dust exceeding.
The utility model content
The purpose of this utility model is to be discharged in tunnel and to construct as space security hidden trouble, a kind of hole sealing device of proposition such as cause that dust transfinites in order to solve in tunnel in construction extraction borehole process in boring the gas dust boring mud of ejection.
The technical solution of the utility model is: spring strut gas dust dedusting hole sealing device, it is characterized in that, and comprise straight-tube shape cavity, pressure spring and blowdown slag pipe; Described pressure spring docks with the straight-tube shape cavity is coaxial, and blowdown slag pipe is connected in the sidewall of straight-tube shape cavity;
The static fire retardant that described straight-tube shape cavity is tubbiness by stitching realizes, both ends of the surface comprise support, and described support comprises the drilling rod hole that is positioned at the end face center and the spoke of jointed rod hole and straight-tube shape cavity end face, and described spoke is for the supports drill rods hole;
Further, described spring strut gas dust dedusting hole sealing device also comprises nozzle, and described nozzle is fixed on the sidewall of straight-tube shape cavity, and described nozzle is connected with water pipe implements to the dust that is created in chamber the dirt that goes out of spraying water;
Described nozzle further is connected with pressure air pipe, makes nozzle ejection water and the mixture of pressing wind;
Described blowdown slag pipe is connected in tubular chamber sidewall, is used for being pressed wind and nozzle water spray to produce go out gas dust after dirt and the mixture ejectment of water of stream and goes out.
The beneficial effects of the utility model are: while due to drilling rod, being drilled into coal seam, boring is blocked by gas dust packing device, after particularly adding outside water or air pressure, the expanded radially of gas dust packing device has further kept the seal of drilling rod working space, so the waste residue that produces in the drilling rod course of work, the methane gas in coal seam are all by packing and externally inject and form the abundant mixture of aqueous vapor slag in the situation of a large amount of dust-proof waters and discharge by pipeline.
