Abstract
The utility model provides a kind of and catches dirt curtain for underground coal mine, it comprises and is arranged on support in tunnel and filtration gauze, described support offers door frame, support and door frame are respectively arranged with filtration gauze, and when door frame is in closed condition, the filtration gauze on support and door frame covers the tunneling boring in tunnel jointly; Cradle top is connected with multiple water spray nozzle by static pressure sprinkler pipe, and the water curtain that water spray nozzle sprays after opening flows along the surface of filtration gauze, and forms filter membrane on the surface of filtration gauze.Compared with prior art, the utility model moves conveniently, cost is low, the tunneling boring covering tunnel is sentenced in the access being arranged on tunnel, the water curtain of water spray nozzle ejection forms filter membrane on the surface of filtration gauze, and coal dust is in contact with it collision under the effect of tunnel air-flow, improves efficiency of seizing dust, more effectively can remove the respirable dust in tunnel, protection workman's is healthy; Support is offered door frame and free in and out tunnel to facilitate workman.
Description
Technical field
The utility model relates to the purification water curtain of the coal dust produced in a kind of effective reduction coal production process, specifically a kind ofly catches dirt curtain for underground coal mine.
Background technology
Coal dust is one of major casualty in coal production, is the emphasis of colliery one through three prevention, mining, digs well, explosion, transport, all can produce coal dust in the manufacturing process such as lifting.The harmfulness of coal dust is very large, and the worker of long campaigns underground coal mine work easily causes tuberculosis, is subject to stop, easily causes personal injury in operation in worker's sight line of height dust work place work; On the other hand, coal dust has explosion hazard, easily dust explosion accident occurs, and brings very large threat to the safety in production of mine.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, water curtain is caused to fly away windward, can not reach real tunneling boring to cover, cause part coal dust to pass through, dust-laying effect is not obvious.
Summary of the invention
Technical assignment of the present utility model is for the deficiencies in the prior art, provides a kind of and catches dirt curtain for underground coal mine.
The utility model solves the technical scheme that its technical problem adopts:
A kind ofly catch dirt curtain for underground coal mine, comprise and be arranged on support in tunnel and filtration gauze, described support offers door frame, described support and door frame are respectively arranged with filtration gauze, and when door frame is in closed condition, the filtration gauze on support and door frame covers the tunneling boring in tunnel jointly; Described cradle top is connected with multiple water spray nozzle by static pressure sprinkler pipe, and the water curtain that water spray nozzle sprays after opening flows along the surface of filtration gauze, and forms filter membrane on the surface of filtration gauze.
The inside and outside both sides of described door frame are respectively arranged with handle.
The bottom of described support and door frame is movably set with aqua storage tank.
Be interconnected between above-mentioned multiple water spray nozzles.
Of the present utility modelly a kind ofly catch dirt curtain compared with prior art for underground coal mine, the beneficial effect produced is:
The utility model simplicity of design, move conveniently, be arranged on the access place in tunnel, cover the tunneling boring in tunnel, the water curtain of water spray nozzle ejection forms filter membrane on the surface of filtration gauze, the coal dust produced in coal production process swims in tunnel, and under the effect of tunnel air-flow with filter membrane contact-impact, total and reach the object of catching dirt, improve efficiency of seizing dust, particularly effectively can remove the respirable dust in tunnel, protection workman's is healthy; Meanwhile, door frame offered by support, tunnel and external environment are kept apart, door frame arranges handle, facilitate workman to free in and out tunnel, and can not affect and catch dirt effect; On the other hand, the utility model material requested is few, and cost is low, fast clean, can also collect by the water that filtration gauze lands, avoid the entrance in tunnel or exit too muddy, facilitate workman to pass in and out.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In figure, 1, support, 2, door frame, 3, filtration gauze, 4, water spray nozzle, 5, static pressure sprinkler pipe, 6, handle, 7, aqua storage tank.
Detailed description of the invention
Below in conjunction with accompanying drawing 1, a kind of dirt curtain of catching for underground coal mine of the present utility model is described in detail below.
As shown in Figure 1, of the present utility modelly a kind ofly catch dirt curtain for underground coal mine, it comprises and is arranged on support 1 in tunnel and filtration gauze 3, described support 1 offers door frame 2, the inside and outside both sides of described door frame 2 are respectively arranged with handle 6, described support 1 and door frame 2 are respectively arranged with filtration gauze 3, and when door frame 2 is in closed condition, the filtration gauze 3 on support 1 and door frame 2 covers the tunneling boring in tunnel jointly; Described support 1 top is connected with multiple water spray nozzle 4 be interconnected by static pressure sprinkler pipe 5, and the water curtain that water spray nozzle 4 opens rear ejection flows along the surface of filtration gauze 3, and forms filter membrane on the surface of filtration gauze 3; As preferably, the bottom of described support 1 and door frame 2 is also movably set with aqua storage tank 7.
During use, open static pressure sprinkler pipe 5, spray water curtain by water spray nozzle 4 and form filter membrane on filtration gauze 3, the coal dust in tunnel and external environment are isolated; Open door frame 2 by handle 6, facilitate workman to pass in and out tunnel; Fall in aqua storage tank after the water curtain part that water spray nozzle 4 sprays flows through filtration gauze 3, to avoid directly dropping in tunnel, make the muddy mud of road.
Of the present utility model a kind of for underground coal mine to catch its processing and fabricating of dirt curtain simple and convenient, processing and fabricating shown in by specification accompanying drawing.
Except the technical characteristic described in manual, be the known technology of those skilled in the art.
