Abstract
The utility model relates to a kind of for firedamp taking-out discharging drilling orifice dust catcher, the housing rear side of this drilling hole dust collector device is provided with back-up ring and flange, near flange place, install external spraying, flange and external spraying all adopt welding manner to be fixed on housing, internal spraying adopts welding manner to be fixed on disk, and dust cover is directly enclosed within on disk and adopts rope or iron wire encircling.During use, the coal dust of discharging in drilling, along the landing of deduster inwall, is discharged discharging opening through internal spraying after coal dust is moistening in dust cover, and a small amount of coal dust that external spraying overflows back-up ring place sprays moistening, thereby reaches the effect of safe and efficient dedusting.
Description
Technical field
The utility model relates to a kind of dust arrester, is specially adapted to the orifice dust catcher that gas discharge in mine boring is drilled.
Background technology
Region outburst prevention measures comprises exploitation topping and takes out in advance coal-bed gas two classes.Single coal bed can be adopted because of unprotect layer, only has and will take out in advance the effective means of coal-bed gas as region outburst prevention measures.During China's coal-mine seam mining construction firedamp taking-out discharging drilling, owing to adopting, dry drilling and coal seam are drier, in drilling construction process, often cause coal dust to fly upward, produce serious dust pollution, to operating personnel is healthy, cause great harm, increase the probability of suffering from coal pneumoconiosis, and because part mine coal dust has explosivity, this is major safety risks for safety management.The current main technology adopting is the measures such as aperture spraying, full section spraying, and dust removing effects is general, and being carried out production strictly in line with rules and regulations in scene impacts with safe mass standardized management, to follow-up work, carries out and brings inconvenience.
Summary of the invention
The efficiency of dust collection in aperture while drilling for the boring of raising gas discharge in mine, the utility model provides a kind of orifice dust catcher, this orifice dust catcher adopts inside and outside shower nozzle to combine, the coal dust that the process of drilling is produced is moistening rear delivery port fully, effectively reduce drilling construction operation dust concentration, improve site work environment, and this dedusting structure is simple, lightweight and portable in volume, convenient to use.
The utility model solves the technical scheme that its technical problem adopts: this orifice dust catcher comprises back-up ring 1, flange 2, disk 3, external spraying 4, internal spraying 5, dust cover 6, housing 7, this orifice dust catcher is provided with a similar rifle shape housing 7 cylindraceous, be provided with the roll extrusion decorative pattern that makes its surface roughening, at deduster tail end, a back-up ring 1(back-up ring being set adopts scrap leather band or cushion rubber to process, there is certain pliability), back-up ring 1 is adopted and is bolted connection with flange 2, reduces this place's coal dust and overflows; In deduster aperture, place installs adjustable external spraying 4 shower nozzles; Inside scum pipe end disc portion, shape triangular in shape is installed three internal spraying 5 shower nozzles, and for increasing dust emission space, external application air duct fabric carries out totally-enclosed as dust cover 6, sets up stop valve to control injection flow rate.Flange 2 and external spraying 3 all adopt welding manner to be fixed on housing 7, and internal spraying 4 adopts welding manner to be fixed on disk 5, and dust cover 6 is directly enclosed within on disk 5.During use, orifice dust catcher front end is embedded to wedging in boring, in opening in executing brill process, external spraying carries out moistening to coal dust simultaneously, moistening coal dust is discharged discharging opening along dust cover, is directed on belt conveyor and transports in time, thereby reach safe and efficient dust removing effects.
The beneficial effects of the utility model are, in this orifice dust catcher adopts, external spraying combines coal dust is carried out to abundant moistening delivery port, and dust removing effects is obvious, and operating environment is improved, carry out production strictly in line with rules and regulations in scene and quality standardization is ensured, and lightweight and portable in volume, convenient to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In Fig. 1, this orifice dust catcher comprises back-up ring 1, flange 2, external spraying 3, internal spraying 4, disk 5, dust cover 6, housing 7, this orifice dust catcher is provided with a similar rifle shape housing 7 cylindraceous, be provided with the roll extrusion decorative pattern that makes its surface roughening, the rear side of housing 7 is provided with back-up ring 1 and flange 2, both adopt and are bolted connection, reducing this place's coal dust overflows, near flange 2 places, install external spraying 3, flange 2 and external spraying 3 all adopt welding manner to be fixed on housing 7, internal spraying 4 adopts welding manner to be fixed on disk 5, dust cover 6 is directly enclosed within on disk 5 and adopts rope or iron wire encircling.During use, the coal dust of discharging in drilling is along the landing of deduster inwall, through internal spraying 4, discharges discharging opening after coal dust is moistening dust cover 6 is interior, and a small amount of coal dust that overflow at 3 pairs of back-up ring 1 places of external spraying sprays moistening, thereby reaches the effect of safe and efficient dedusting.
