Abstract
The utility model discloses a secondary negative pressure dust settling device of a coal mining machine. The secondary negative pressure dust settling device is provided with a body, wherein the body is used for being fixedly connected with the coal mining machine; a nozzle rack is arranged in the body and is provided with a plurality of nozzles; the nozzles are communicated with a water inlet pipe; each nozzle is correspondingly covered by a spray cover; and the spray covers are cylinders with front and rear open ends. When the secondary negative pressure dust settling device is used, coal dust enters the nozzle covers to form secondary dust settlement, so that the dust settling efficiency is increased; due to the flow guide effect of the nozzle covers, the water fog has a long jet range, and the atomization effect is good; and the nozzles are arranged in the body, are difficult to damage by collision and are durable.
Description
Technical field
The utility model relates to dedusting, the device for reducing dust that a kind of colliery silo shearer uses, especially a kind of dust settler that adopts negative pressure to realize the secondary depositing dust, a large amount of coal smokes that produce when being used to reduce the coal-winning machine coal cutting.
Background technology
Coal miner spray depositing dust, dust guard under the existing well generally are to adopt water under high pressure directly to spray, water smoke and the disposable depositing dust that contacts of coal smoke, and have the part coal smoke before water smoke arrives, to be blown to such an extent that fly upward everywhere by it, and can not effectively dust be caught, dust removing effects is poor.
Summary of the invention
The purpose of the utility model provides a kind of coal-winning machine secondary negative pressure dust settler, solves the defective of the existing direct atomizing de-dusting weak effect of water under high pressure.
The purpose of the utility model realizes as follows: a body is arranged; Body is used for being connected with coal-winning machine fixing; Injection nozzle carrier is set in body, plurality of nozzles is set on injection nozzle carrier, nozzle is communicated with water inlet pipe; Be covered with spray cap on corresponding each nozzle, spray cap is the cylindrical shell of front and back end opening.When spraying, the jet place of nozzle forms negative pressure, and coal dust gets in it from the spray cap rear end, mixes forming the secondary depositing dust with water smoke, can improve dust-laying effect like this.
Spray cap is connected on the body, and is consistent with the nozzle direction.
Nozzle and injection nozzle carrier are arranged on internal body.
The beneficial effect of the utility model is: coal dust gets into spray cap and forms the secondary depositing dust, has improved depositing dust efficient; Because the guide functions of spray cap makes the water smoke far firing range, atomizing effect is good; Nozzle is arranged in the body, is difficult for damaged in collision, and is durable in use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
With reference to Fig. 1, a body 4 is arranged, injection nozzle carrier 3 is set in body 4; Injection nozzle carrier 3 is communicated with water inlet pipe 5, and plurality of nozzles 2 is set on injection nozzle carrier 3, and nozzle 2 is communicated with injection nozzle carrier 3; Corresponding each nozzle 2 is provided with spray cap 1, and spray cap 1 is the cylindrical shell of front and back end opening, and spray cap 1 is connected on the body 4; Consistent with nozzle 2 directions, and make nozzle 2 and injection nozzle carrier 3 be in body 4 inside.During use, be fixed on the coal-winning machine, connect high-pressure rubber pipe, carry water under high pressure, can normally use through the high pressure pumping plant at the coal-winning machine two ends through pinhole.The utility model is converted into the steam fog stream barrier of the dust source of control coal mining machine roller coal cutting generation to external diffusion with water under high pressure; And become local dust-laden air decontamination dust arrester; The purification that realization is produced dirt to the coal mining machine roller coal cutting, prevention and minimizing dust are to external diffusion.
