Abstract
The utility model discloses an underground coal mine dust-proof water curtain, and belongs to the technical field of mine used dust-proof water curtain, and aims to solve the technical problem to provide a dust-proof water curtain with full cross section cover and obvious dust fall effect. The underground coal mine dust-proof water curtain comprises a static pressure sprinkler pipe fixedly arranged at the top of a roadway, a plurality of water curtain nozzles communicating with the static pressure sprinkler pipe and dust collecting nets mounted on weather sides of the water curtain nozzles, the water curtain nozzles are arranged at 45 degrees and face wind, the water curtain formed after the water curtain nozzles are switched on can cover the full cross section and the dust collecting nets comprises an aluminum alloy frame and metal window screening fixed on the frame.
Description
Technical field
The utility model belongs to mining dust-proof water curtain technical field, is specifically related to a kind of mine underground dustproof water screen that comprises Dust collecting net.
Background technology
Coal dust is the emphasis of one of major casualty in coal production ，Shi colliery one through three prevention, in the manufacturing processes such as coal mining, driving, explosion, transportation, lifting, all can produce coal dust; The harm of coal dust is very large, the worker who is engaged in for a long time colliery underground work easily causes pneumoconiosis, worker's sight line in high concentrate dust operation place is subject to stop, in operation, easily cause personal injury, and coal dust has explosion hazard, easily there is dust explosion accident, to mine safety production, bring serious threat.
Therefore dust suppression in mine is a very important job, traditional dust-settling technology is mainly by arranging dustproof water screen in coal dust water filling, transfer point spraying and tunnel, conventional dustproof water screen is due to distinguished and admirable effect, cause water curtain to fly away windward, can not reach real full section covers, cause part coal dust to pass through, dust-laying effect is not remarkable.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved is: a kind of full section covering, significant dustproof water screen of dust-laying effect realized is provided.
For solving the problems of the technologies described above, the utility model provides a kind of mine underground dustproof water screen, comprise the static pressure sprinkler pipe that is fixedly installed on top, tunnel, a plurality of water spray nozzles with static pressure sprinkler pipe UNICOM, described a plurality of water spray nozzle windward 45 degree arranges, and the water curtain that described a plurality of water spray nozzle forms after opening can cover full section, and described dustproof water screen also comprises the Dust collecting net that is arranged on above-mentioned water spray nozzle weather side.
Described Dust collecting net consists of aluminum alloy frame and the metal window screening being fixed on frame.
The utility model compared with prior art, has following beneficial effect.
1, on the basis of traditional dustproof water screen, increased Dust collecting net, when distinguished and admirable in tunnel carried coal dust through Dust collecting net, be subject to the impact of Dust collecting net, form eddy current, increase coal dust by the time in Gai Duan tunnel, lengthened the time of contact of coal dust and water curtain, and described water spray nozzle windward 45 degree is installed, open the full section that the water curtain forming after water spray nozzle can cover tunnel, dust removing effects highly significant, has improved worker's working environment greatly.
2,, due to the raising of dust-laying effect, reduced the frequency of rinsing tunnel, the input of saving water resource and dustproof fund.
3, described Dust collecting net is simple in structure, is easy to install, and makes material and easily buy, and low price, reduces costs input.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of Dust collecting net in the utility model.
In figure: 1 is that static pressure sprinkler pipe, 2 is for water spray nozzle, 3 is for Dust collecting net, 4 is for frame, 5 is for metal window screening, 6 is for installing suspension ring.
The specific embodiment
As shown in Figure 1, described mine underground dustproof water screen, comprise the static pressure sprinkler pipe 1 that is fixedly installed on top, tunnel, a plurality of water spray nozzles 2 with static pressure sprinkler pipe 1 UNICOM, described a plurality of water spray nozzle 2 windward 45 degree arranges, and the water curtain that described a plurality of water spray nozzle 2 forms after opening can cover full section, and described dustproof water screen also comprises the Dust collecting net 3 that is arranged on above-mentioned water spray nozzle 2 weather sides.
Described Dust collecting net 3 consists of aluminum alloy frame 4 and the metal window screening 5 being fixed on frame 4.
In actual use, according to the width in tunnel and traffic condition, determine width and the height of Dust collecting net 3, require in principle the width of Dust collecting net 3 to equal the width in tunnel, the height of Dust collecting net 3 is generally selected 1.2 ~ 1.5m, be the first half that Dust collecting net 3 is mounted on tunnel, do not affect the normal use in tunnel.
During installation, first at the complete local top, tunnel of roadway support, static pressure sprinkler pipe 1 and water spray nozzle 2 are installed, described water spray nozzle 2 is a plurality of, and when the actual installation number of described water spray nozzle 2 is all opened with it, formed water curtain can cover the required number of the full section in tunnel and determines, above-mentioned water spray nozzle 2 windward sides 45 degree are installed.
Then at the weather side of water spray nozzle 2, Dust collecting net 3 is installed, on the frame 4 of described Dust collecting net 3, be provided with suspension ring 6 are installed, described Dust collecting net 4 is fixed on the hook of top, tunnel setting by suspension ring 6 are installed, can be mobile assembled and disassembled, when the coal dust on Dust collecting net is too thick, can disassemble after clearing up and continue to install and use.
The utility model by having increased Dust collecting net on the basis of traditional dustproof water screen, when distinguished and admirable in tunnel carried coal dust through Dust collecting net, be subject to the impact of Dust collecting net, form eddy current, increase coal dust by the time in Gai Duan tunnel, lengthened the time of contact of coal dust and water curtain, and described water spray nozzle windward 45 degree is installed, open the full section that the water curtain forming after water spray nozzle can cover tunnel, dust removing effects highly significant, has improved worker's working environment greatly; Due to the raising of dust-laying effect, reduced the frequency of rinsing tunnel, the input of saving water resource and dustproof fund; Above-mentioned Dust collecting net simple in structure, is easy to install, and makes material and easily buy, and low price, reduces costs input.
By reference to the accompanying drawings the specific embodiment of the present utility model is explained in detail above, but the utility model is not limited in above-mentioned embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.
