Description
Technical field
The utility model belongs to dust falling in coal mining equipment, specifically a kind of device for reducing dust.
Background technology
Along with improving constantly of each production link machinery degree such as colliery digging, raw coal output constantly increases, and the absolute throughput of dust increases, and causes very large harm to the operating environment of getting working face.In conjunction with actual conditions and the existing dustproof facilities in my ore deposit, can not well reduce dust concentration in getting working face return.By increasing dustproof water screen technological means, mainly spraying water curtain with linear water curtain thus reaching the object of depositing dust, but linear water curtain is gone into the well and installed loaded down with trivial details and should not carry, cost is also higher simultaneously.
Summary of the invention
The utility model, in order to solve the problem that in Coal mine excavation, dust works the mischief to the operating environment of getting working face, provides a kind of device for reducing dust.
The utility model takes following technical scheme: a kind of device for reducing dust, and comprise and be arranged on Dust collecting net in coal-face return aircourse and annular water curtain, Dust collecting net is provided with pedestrian's door, and Dust collecting net weather side is provided with shower nozzle; The main body that annular water curtain comprises fastening devices and fixed by fastening devices, main body is provided with the snap joint be connected with water pipe, the all sides of main body are evenly distributed with some spray nozzles, the described spray nozzle shower nozzle comprised as shower nozzle skeleton emits, be arranged on shower nozzle emits inner spiral spray core and is arranged on the feed liquor distribution grid that shower nozzle emits inlet place, feed liquor distribution grid is evenly provided with some feed liquor apertures, spiral spray core is notch cuttype cylinder, is provided with double spiral groove outside spiral spray core.
Described Dust collecting net filter opening is 8 orders.
The main body of described annular water curtain is that all sides have been evenly arranged 6 spray nozzles.
Described feed liquor distribution grid is evenly equipped with 8 feed liquor apertures.
Dust collecting net uses steel pipe to be woven to several fixed frames, by multiple fixing framework composition together, Dust collecting net size can be specifically adjusted flexibly like this according to the size of section, roadway full-fracture-surfacanchoring-rod can be covered and reach tunneling boring dust-laying effect, and pedestrian's door is set on Dust collecting net, facilitate pedestrian to pass through.Dust collecting net weather side mounting spray head, Dust collecting net can play dust-laying effect better in conjunction with shower nozzle water spray, and Dust collecting net can also be carried out auto-flushing by thin water spray makes Dust collecting net play good dust-laying effect constantly.
Be evenly arranged 6 spray nozzles at its steel pipe sidewall, form complete " annular " water curtain, this water curtain can form one water curtain and cover section, plays double-deck dust-laying effect.Water curtain volume significantly reduces by annular water curtain, finally reaches the input reducing material, reduce cost, and dust-laying effect promotes further.
In use, current enter spray nozzle internal helicoid spray core by aperture uniform on feed liquor distribution grid to annular water curtain, then by forming strong eddy flow state during spiral spray core, by uniform atomizing, can satisfy the demand after ejection.
At the inner ingenious introducing helical structure of spray nozzle, the benefit done like this is the amount of liquid according to being atomized, by the design to spiral fluted width and the degree of depth, can easier regulate flow, and the increasing of flow can not impact eddy flow effect, simultaneously owing to adopting helical structure, shower nozzle is made to stop using or have self-cleaning ability after not easily forming blocking and blocking in use procedure.
Compared with prior art, the utility model Dust collecting net weather side mounting spray head, Dust collecting net can play dust-laying effect better in conjunction with shower nozzle water spray, and Dust collecting net can also be carried out auto-flushing by thin water spray makes Dust collecting net play good dust-laying effect constantly.
Water curtain volume significantly reduces by arranging of water curtain of annular, finally reaches the input reducing material, reduce cost, and dust-laying effect promotes further.Helical structure is introduced in spray nozzle inside in annular water curtain, the benefit done like this is the amount of liquid according to being atomized, by the design to spiral fluted width and the degree of depth, can easier regulate flow, and the increasing of flow can not impact eddy flow effect, simultaneously owing to adopting helical structure, shower nozzle is made to stop using or have self-cleaning ability after not easily forming blocking and blocking in use procedure.
