Technical field
The utility model belongs to 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 turning is executed in optimization.
Background technology
Coal mine gas, dust accident are one of disasters of down-hole, if there is gas, dust accident, not only can heavy damage production environment, and can cause casualties, cause huge loss to 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 geologic sedimentation effect, a large amount of toxic and harmfuls such as gas in coal seam, have been overstock, in order to realize safe digging, generally, before digging, first to arrange special-purpose gas pumping tunnel, 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, particularly many mines enter after deep horizontal, coal seam gas-bearing capacity, pressure all will increase, because executing the gas dust producing in brill process and turning the refuses such as slag, can be ejected into construction space, 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 brill process and can be released in tunnel, cause the potential safety hazards such as serious gas exceeding limit and dust exceeding.
Utility model content
The purpose of this utility model is to be discharged into security hidden trouble, a kind of hole packer of proposition such as execute that working space causes that dust transfinites in tunnel in order to solve in the extraction borehole process of constructing the gas dust boring mud spraying in boring in tunnel.
The technical solution of the utility model is: a kind of hole packer, it is characterized in that, and comprise straight-tube shape cavity, pressure spring, blowdown slag pipe, atomization unit and nozzle; Described pressure spring docks with straight-tube shape cavity is coaxial, and blowdown slag pipe is connected in the sidewall of straight-tube shape cavity;
Described straight-tube shape cavity skin-material is static fire retardant, and both ends of the surface comprise support, and described support comprises and be positioned at the drilling rod hole at end face center and the spoke of jointed rod hole and straight-tube shape cavity end face, and described spoke is used for supporting bull stick hole;
Described atomization unit comprises hybrid chamber main body, water filling port, air pressure mouth and exit portal are set in hybrid chamber main body, described air pressure mouth is relative with exit portal, water filling port is between air pressure mouth and exit portal, air pressure mouth is connected respectively high-pressure air source and water source with water filling port, and water filling port waterflood direction is vertical and air pressure mouth gas input direction; The exit portal of atomization unit is connected with nozzle; Described nozzle is fixed on the sidewall of straight-tube shape cavity the position over against blowdown slag pipe.
Described blowdown slag pipe is connected in straight-tube shape cavity wall, for being gone out pressing wind and nozzle water spray to produce go out gas dust after dirt and the mixture ejectment of water of stream.Described atomization unit is fixedly attached to and is gone out on dirt cavity by support.
The beneficial effects of the utility model are: while being drilled into coal seam due to drilling rod, boring is blocked by gas dust packing device, particularly will add after 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 producing 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.

Description of reference numerals: cylindrical body chamber 1, pressure spring 11, support 12, drilling rod hole 121, spoke 122, atomization unit 2, hybrid chamber main body 21, air pressure mouth 22, exit portal 23, water filling port 24, pipeline 25, nozzle 26, support 27, blowdown slag pipe 3.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, Figure 2 and Figure 3, the hole packer of the present embodiment, comprises straight-tube shape cavity 1, pressure spring 11, blowdown slag pipe 3, atomization unit 2 and nozzle 26; Described pressure spring 11 docks with straight-tube shape cavity 1 is coaxial, and blowdown slag pipe 3 is connected in the sidewall of straight-tube shape cavity; Straight-tube shape cavity skin-material is static fire retardant, forms the tubbiness of an end opening, and wherein bung is used for sealing and executes boring, and the bucket end connects pressure spring.Straight-tube shape cavity both ends of the surface comprise support 12, and described support comprises and be positioned at the drilling rod hole 121 at end face center and the spoke 122 of jointed rod hole and straight-tube shape cavity end face, and described spoke is used for supporting bull stick hole.Atomization unit 2 comprises hybrid chamber main body 21, water filling port 24, air pressure mouth 22 and exit portal 23 are set in hybrid chamber main body, described air pressure mouth is relative with exit portal, water filling port is between air pressure mouth and exit portal, air pressure mouth is connected respectively high-pressure air source and water source with water filling port, and water filling port waterflood direction is vertical and air pressure mouth gas input direction; The exit portal of atomization unit is connected with nozzle 26 through piping 25; Described nozzle is fixed on the sidewall of straight-tube shape cavity the position over against blowdown slag pipe.Whole atomization unit is fixedly attached on straight-tube shape cavity 1 by support 27.Blowdown slag pipe is connected in straight-tube shape cavity wall, in being gone out pressing wind and nozzle water spray to produce go out gas dust after dirt and the mixture ejectment of water of stream.
