At present, go out dirt, measurements for reduction of common working face has 2 kinds of external spraying and internal spraying, and modern coal-winning machine is mostly used
The inside and outside method being combined of spraying.Spray effect has certain relation with pressure of supply water, and pressure of supply water can not be less than certain
Value, atomizing effect is not reached otherwise.Atomisation pressure is low, it is distinguished and admirable when adding coal cutting stopped by coal-winning machine, the high speed of front roll
Rotation and against the wind spraying, strong vortex is produced in coal-winning machine front end, a large amount of high concentration dust-contained airflows is diffused into coal-winning machine department
The working space of machine.
The content of the invention
The present invention provides a kind of coal machine sprayer unit, diffusion will be raised outside coal dust in the roller high speed rotation for solving coal-winning machine
Problem.
To achieve the above object, the technical solution adopted by the present invention is：Coal miner spray device, including it is arranged on coal-winning machine
The spray nozzle device at roller rear and the pressure duct of water under high pressure is provided for spray nozzle device, multiple spray is included on the spray nozzle device
Mouthful, towards coal mining machine roller rear, in inner side water inlet end for uniform level is highly set, spout goes out multiple spouts spout in outside
Water end (W.E.) is risen by the lateral opposite side level height of spray nozzle device one, and water side difference in height is lateral another by one on the outside of adjacent spout
Side gradually increases；Access pressure duct in the spout rear portion.
Pressure duct includes the pressure duct of connection high-pressure hydraulic pump, and pressure duct is provided with separator tube and is connected to high-pressure hydraulic pump
Water inlet pipe, separator tube is provided with control valve, and pressure duct is provided with pressure gauge, and the inlet pipeline of high-pressure hydraulic pump is passed through water tank
It is interior.
Water tank is soft water pond, and also including back pool, back pool collects the dustfall water that coal-winning machine sprays, and is provided with back pool
Filter device, the backwater after filtering is delivered in water tank through water pump.
The water inlet pipe of pressure duct to be accessed and set filter at water tank, water pipe is set on water tank and accesses running water.On spray nozzle device
Portion is installed with connecting plate, and connecting plate extends rearward through bolt and is fixed on coal-winning machine.
The utility model has the advantage of：The water under high pressure spray of ejection at an angle high speed injection to coal mining machine roller
Section, form vortex field, the air for making dust content high is inhaled into high speed water mist vortex to be formed and hinders dirt source empty to mining
Between the high-pressure aerial fog barrier that spreads, due to the suction function of water smoke vortex, very strong negative pressure is produced around device for reducing dust, can
Spray again and purify by the dust content air suction high nearby of coal-winning machine end and roller and with spray.Simultaneously can be to ore deposit
Waste water in road is reused after carrying out filtering utilization, and softening, serves using water wisely, the mesh of extension device service life
's.

Specific embodiment
Coal miner spray device, including be arranged on the spray nozzle device on coal-winning machine two ends roller rear and be spray nozzle device
The pressure duct of water under high pressure is provided, multiple spouts are included on the spray nozzle device, spout sprays towards coal mining machine roller rear, multiple
Mouth is in inner side water inlet end for uniform level is highly set, and spout is high by the lateral opposite side level of spray nozzle device one in outside water side
Degree rises, and water side difference in height is gradually increased by a lateral opposite side on the outside of adjacent spout；Access high in the spout rear portion
Pressure pipe road.
Pressure duct includes the pressure duct of connection high-pressure hydraulic pump, and pressure duct is provided with separator tube and is connected to high-pressure hydraulic pump
Water inlet pipe, separator tube is provided with control valve, and pressure duct is provided with pressure gauge, and the inlet pipeline of high-pressure hydraulic pump is passed through water tank
It is interior.Water tank is soft water pond, and also including back pool, back pool collects the dustfall water that coal-winning machine sprays, and filtering dress is provided with back pool
Put, the backwater after filtering is delivered in water tank through water pump.
The water inlet pipe of pressure duct to be accessed and set filter at water tank, water pipe is set on water tank and accesses running water.On spray nozzle device
Portion is installed with connecting plate, and connecting plate extends rearward through bolt and is fixed on coal-winning machine.
Water forms water under high pressure after high-pressure pump pressurizes, and high-pressure water mist sprays from the front end of device for reducing dust, its height for spraying
High speed injection, on coal mining machine roller, forms the high pressure gas for hindering dirt source to be spread to coal mining space to pressure spray stream at an angle
Mist barrier, due to the suction function of water smoke, produces very strong negative pressure around device for reducing dust, can be by coal-winning machine end and roller
The air suction high of neighbouring dust content simultaneously sprays and purifies again with spray.From high velocity mist, gas that device for reducing dust front end sprays
Flow and pass through from the section of roller, formed vortex field is rotated with enough energy hole rollers, make the sky that dust content is high
Gas is inhaled into high speed water spray, and wherein most dust can be combined with droplet, settled, and air is purified.Injection hydraulic pressure
It is set as during 2~6 MPa effect preferably, and requirement can be met, it is parabola shaped that its variation tendency is that Open Side Down
Shape.Therefore, injection hydraulic pressure should be set as 6MPa or so.According to the impact analysis injection water injection of the injection half-angle to nozzle
Effect is best at 20 ° or so.Reused after filtering utilization, and softening are carried out to the waste water in drive, serve using water wisely
Purpose.
