Abstract
The utility model relates to a wind current decontamination device used for the local ventilation of an underground mining cabin in coal mine, comprising a local blower, a silencer, the guider of the silencer and an air duct. The wind current decontamination device is characterized in that an outer shell at the back part of the silencer and the top end of the guider of the silencer are drilled with holes, a water pipe is connected between two holes, one end of the water pipe at the hole leading to the top end of the guider of the silencer is provided with a spray nozzle, and the other end of the water pipe is connected with a water source via a valve. The back part of the air duct is connected with a sewage collecting drum, and the shell of the sewage collecting drum is provided with a drainage pipe. The wind current decontamination device is used for eliminating dust sucked in the air duct by the local blower and feeding purified air to a mining working surface.
Description
The utility model relates to the air decontamination device in the getting working face local ventilation work under a kind of coal mine.
At present, the air quantity of getting working face is carried and is relied on secondary fan to realize that in the down-hole mining production process, working surface can produce a large amount of dust under the coal mine, to underground air is polluted.Particularly adopt in digging is produced in the working surface of series ventilation mode, last working surface produces dust in process of production, and major part is imported into next working surface by secondary fan, causes dust to gather, and concentration strengthens, and has increased the danger of dust explosion.In suffering the air ambient of severe contamination, operate simultaneously, can inhale tuberculosis, can directly threaten the health of down-hole miner health.
In order to address the above problem, implement every requirement that coal parent company strengthens miner's labor protection, each production unit is all successively adopted various measures.As blowing out the use water stemming material in the down-hole, adopt wet drilling, the delivery spraying is used in transportation, and the operator wears anti-dust respirator or the like, but working environment at coal mines still can not well be improved.Chinese patent discloses a kind of blower fan baffler for No. 88205341, though depositing dust is had certain effect.But the purpose of this patent is intended to reduce noise, does not have thoroughly to solve the air decontamination problem in the local ventilation work under the coal mine.
The purpose of this utility model is to overcome the deficiency in the above-mentioned background technology, and a kind of dust that is sucked air duct by secondary fan of eliminating effectively is provided, and carries the air decontamination device of the air that is cleaned to getting working face.
The purpose of this utility model is achieved in that this distinguished and admirablely staticizes device and comprise that secondary fan, baffler, baffler guide device, air duct into, it is characterized in that guiding the tip into baffler on the shell at baffler rear portion respectively is drilled with a hole, be connected with water pipe between two holes, water pipe end in the hole that leads to the baffler back shell joins by valve and water source, and the water pipe end of guiding the hole at device tip towards baffler into is equipped with spraying nozzle.Be connected to the sewage collecting tube in the air duct back, on its barrel shell drain pipe be housed.When local ventilating fan starts, carry when distinguished and admirable to getting working face, open the water source valve, adjust hydraulic pressure and flow, spraying nozzle is sprayed in air duct, because the effect of hydraulic pressure and wind speed, the water smoke partition wall that forms a segment distance in air duct is sucked in the air duct by secondary fan, contaminated wind circulation is cleaned when crossing this vaporific partition wall, and dust is adhered to outside sewage collecting tube and drain pipe expelling tube by water smoke, carries the fresh distinguished and admirable purpose that is cleaned thereby reach to face.
The utility model is compared with background technique, has following effect:
1, reaches 95.15% through this device dust reduction rate of down-hole experiment (test and adopt No. 172 literary composition of Chinese coal parent company (90) coal word " big gun pick dust measuring point is arranged " sampling to test) with standard A GW-90 dust sampler.
2, increase the humidity of the air of the distinguished and admirable outlet of secondary fan, improved the operating environment that is transferred distinguished and admirable down-hole mining working surface.
3, reached the purpose of a tractor serves several purposes such as noise reduction, blowdown.
4, simple in structure, suit on existing equipment, to transform.
Accompanying drawing drawing of the present utility model is described as follows:
Fig. 1 is a structural representation of the present utility model: secondary fan (1), and baffler (2), spraying nozzle (3), water pipe (4), valve (5), air duct (6), sewage collecting tube (7), drain pipe (8) blocks cable (9) fast.
Fig. 2 is a spraying part schematic representation of the present utility model: baffler is guided device (10) into.
Fig. 3 is the utility model sewage collecting part schematic representation: air duct card tube (11).
The utility model is described in further detail below in conjunction with (accompanying drawing) embodiment: the secondary fan of this device (1), baffler (2), air duct (6), sewage collecting tube (7) are by card cable (9) locking fast of air duct circle (11) serial connection back.Changed and adopted the air duct mouth to connect the technology of utilizing the rope made of hemp and galvanized wire colligation in the past, promptly saved the funds spending, improved the local ventilation quality, be fit to abominable operating environment under the coal mine again.On baffler (2) back shell, guide device (10) tip into and respectively be drilled with a hole with baffler, be connected with water pipe (4) between two holes, water pipe (4) end in the hole that leads to the baffler back shell joins by valve (5) and water source, and spraying nozzle (3) is equipped with at water pipe (4) end in the hole of guiding the device tip towards baffler into.Be connected to sewage collecting tube (7) in air duct (6) back, drain pipe (8) is housed on its barrel shell, drain pipe is the U type, prevents to produce to leak out sewage can be discharged continuously automatically.The sewage collecting tube of this device makes the inclination angle requirement that monomer spare can adapt to the down-hole mining working surface, and different driving modes such as the gallery of can going up a hill, go down the hill according to working surface during installation are determined the sewage collecting partial distance.Since secondary fan's power difference, hydraulic pressure difference in the water source tube, the nepheloid zone distance is also different, can be according to the character and the dispersion degree of dust, and control hydraulic pressure and flow are to reach purifying effect.
Claims (3)
1, a kind of air decontamination device comprises that secondary fan, baffler guide device, air duct into, it is characterized in that:
A, on the shell at baffler rear portion and baffler guide the device tip into and respectively be drilled with a hole, be connected with water pipe between two holes, water pipe end in the hole that leads to the baffler back shell joins by valve and water source, and the water pipe end of guiding the hole at device tip towards baffler into is equipped with spraying nozzle;
B, behind tube, be connected with the sewage collecting tube, on its barrel shell drain pipe be housed.
