Technical field
The present invention relates to coal mine apparatus field, particularly a kind of drilling rod dust gathering arrester.
Background technology
In the energy industry of China, coal accounts in China's primary energy production and consumption structure about 70%, therefore, coal will be the main energy sources of China within quite long period, current, the quick growth of China's economy, have higher requirement, and the coal mining of China 95% is underground job to Dissertation of Development of Coal Industry.As everyone knows, working environment at coal mines is severe, gas and coal dust are two dangerous matter sources that mine is larger to harm, wherein the gas harm of Gas Outburst that can cause is very serious, mainly destroy down-hole facility, equipment and ventilation system, cause down-hole wind current control, personnel suffocate, this affair fire can cause gas combustion, blast and dust explosion accident, causes a tremendous loss of lives and property loss; Dust is to the harm of health also very large: suck a large amount of mine dusts for a long time, and the lighter causes respiratory inflammation, heavyly all causes pneumoconiosis; Skin contamination mine dust, blocked pore, can cause skin disease or inflammation, and mine dust also can stimulate eye mask; Coal dust can explode under certain condition, and coal-dust explosion is one of large disaster in colliery five, and for gaseous mine, during generation gas explosion, coal dust also likely participates in blast simultaneously, and explosive damage degree is aggravated; Mine dust increases, and can reduce Work places and tunnel visibility, not only affect efficiency, also easily causes error code operation, erroneous judgement, often causes operating personnel's injures and deaths; Also can cause certain harm to plant equipment, mine dust energy acceleration mechanical weares and teares, reduction of service life, increases personnel to the maintenance load of equipment.Therefore, absorb process coal dust under mine and the equipment of gas is very important, when ore deposit downhole tool is exploited, can produce a large amount of coal dusts and methane gas, the safety for miner, equipment and down-hole has very large harm.
Summary of the invention
For solving this problem existed in above-mentioned technology, the invention provides a kind of boring dust gathering arrester that can absorb coal dust and discharge methane gas.
The present invention is for solving the problems of the technologies described above, the technical scheme adopted is: a kind of boring dust gathering arrester, comprise a columned housing, be connected at housing two ends into brill mouth and go out to bore mouth, a side along shell length direction is provided with the gas pumping mouth for connecting transfer tube, a slag trapping box be communicated with enclosure interior is connected in the another side of housing, the lower end of slag trapping box is provided with lower cinder notch, a high-pressure water pipe is penetrated outside described slag trapping box, high-pressure water pipe one end stretched in slag trapping box is provided with just to the atomizer of lower cinder notch, top inner walls being positioned at slag trapping box is provided with the guided plate dropping to slag trapping box for guiding cinder, described enter to bore between mouth and housing be provided with in circular dust ring, described dust ring is hollow tube assembling structure and is connected with the high-pressure air source in the external world, evenly gather towards the gas jetting hole at dust ring center in the inner circle side of dust ring, form one to make the pressure-air through gas jetting hole ejection and close air curtain into brill mouth.
As further setting, a side panel of described guided plate, towards going out to bore mouth and downward-sloping, the end portion of guided plate has the arc groove that drilling rod can be made to pass through.
As further arranging, described high-pressure water pipe one end of stretching out outside housing is provided with high-pressure water inlet hole.
Income effect: be provided with slag trapping box relative to prior art below the housing holding drilling rod, and be provided with high-pressure water pipe on slag trapping box, becomes mud after coal dust mixes by atomizer ejection High-Pressure Water, avoids coal dust and be discharged in mine;
The direction of coal dust transmission is also provided with guided plate, and guiding coal dust drops to slag trapping box, avoids coal dust and overflows from entering to bore mouth, more effectively can absorb coal dust;
Be provided with dust ring with dispersive nozzle entering to bore mouth place, gas can be sprayed in dust ring to entering to bore the closed air curtain of interruption-forming one, preventing methane gas and coal dust from spilling in mine from going out to bore mouth;
Methane gas and coal dust are discharged in mine when having stopped drilling rod work by the present invention, effectively absorb coal dust and have discharged methane gas, and structure is simple, powerful, reduces the danger coefficient in mine.

Detailed description of the invention
Elaborate to embodiments of the invention below in conjunction with accompanying drawing, the present embodiment, premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in Figure 1, a kind of boring dust gathering arrester, comprise a columned housing 8, be connected at the two ends of housing 8 into brill mouth 3 and go out to bore mouth 1, drilling rod stretches into from entering to bore mouth 3 and carries out work from going out to bore after mouth 1 stretches out, a side along housing 8 length direction is provided with the gas pumping mouth 2 for connecting transfer tube, a slag trapping box 9 be communicated with housing 8 inside is connected in the another side of housing 8, the lower end of slag trapping box 9 is provided with lower cinder notch 5, a high-pressure water pipe is penetrated outside described slag trapping box 9, high-pressure water pipe one end stretched in slag trapping box 9 is provided with just to the atomizer 4 of lower cinder notch 5, atomizer 4 is just to lower cinder notch 5, the coal dust dropped downwards is become mud, achieve the effect absorbing coal dust.Top housing 8 inwall being positioned at slag trapping box 9 is provided with the guided plate 6 dropping to slag trapping box 9 for guiding cinder, the direction of slagging tap of coal dust is guided by guided plate 6, dropped in the direction of the downward cinder notch 5 of coal dust, prevent coal dust from spilling in mine from entering to bore mouth 3, coal dust is made to accomplish further to absorb, described enter to bore between mouth 3 and housing 8 be provided with in circular dust ring 7, described dust ring 7 is hollow tubular structure and is connected with the high-pressure air source in the external world, high-pressure air source delivers gas in dust ring 7, evenly gather towards the gas jetting hole at dust ring 7 center in the inner circle side of dust ring 7, under the state of gas jetting hole ejection gas, an air curtain closed into brill mouth can be formed, housing 8 is isolated from the outside.
