Abstract
The utility model relates to a mine underground mechanical wind-water expanding dust removal fan which comprises an outer shell, a gas-mist expanding device and a jetting flow guiding device. The gas-mist expanding device comprises a body, a baffle and a gas-mist mixing pipe, a gas-mist expanding chamber is defined by the baffle and the body, and the gas-mist mixing pipe is communicated with the gas-mist expanding chamber. A filtering screen is arranged at the outlet end of the outer shell and a nozzle is arranged on the baffle. According to the mine underground mechanical wind-water expanding dust removal fan, a wind power expanding device is combined with a high-pressure water jet, so that superposed negative pressure is formed, the capacity of suction of air flow containing dust is greatly increased, the air flow containing dust is thoroughly mixed with water mist air flow so that dust can be thoroughly combined with water mist particles, and therefore damp dust particles can be captured by a dust capturing screen arranged behind the device and the purpose of dust removal is achieved.
Description
Technical field
The utility model relates to mine down-hole spray for dust suppression field.
Background technology
Big gun pick and fully mechanized workface at mine down-hole, blow out in the flue dust, fully-mechanized digging machine cutting process of rear generation the dust produced, the dust that spray operation produces etc., the serious harm operating personnel's is healthy, existing electrical dust-removing blower fan volume is large, noise large, it is large to take up room, it is complicated to install, move difficulty, and the ash-laden gas flow that mechanical Water jet stream dedusting ventilator sucks is little, dust removing effects is limited, is difficult to reach effective dedusting purpose.
The utility model content
The utility model purpose: for overcoming above-mentioned defect, the utility model provides a kind of mechanical type spray dust remover of energy high-effective dust-removing.
Technical scheme: a kind of mine down-hole mechanical air water expansion dedusting fan, comprise shell, aerosol expanding device, flow type pump with injection device, described aerosol expanding device comprises body, baffle plate, aerosol mixing tube, this baffle plate and described body surround aerosol propagation chamber, and described aerosol mixing tube is connected with this aerosol propagation chamber; The port of export of described shell is equipped with filter screen, on described baffle plate, nozzle is arranged.
As preferably, an end of described baffle plate and the joining place of described body are cannelure.
As preferably, described aerosol propagation chamber is metal high-speed eddy structure.
As preferably, described flow type pump with injection device is horn-like.
As preferably, described nozzle is a plurality of, is regularly arranged.
As preferably, the port of export of described shell is equipped with blow-off pipe, and this blow-off pipe is near the inboard of filter screen.
Useful effect: the invention provides a kind of pure mechanical geomantic omen expanded type and suck dust arrester, wind-force expanding device and high-pressure water jet are combined, form the stack negative pressure, greatly strengthened the ability that sucks the ash-laden gas flow, and dust-contained airflow and water smoke air-flow are fully mixed, make the abundant combination of dust and water fog particle, thereby moist dust granules is caught by the Dust collecting net at device rear, to reach the dedusting purpose.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and instantiation, the utility model type technology is described further, but protection domain of the present utility model is not limited to following example.For those skilled in the art; under enlightenment of the present utility model; can from this patent disclosure, directly derive the identical basic deformation of some principles of association; or the substituting of known technology commonly used in prior art; and the identical mutual various combination of feature, the technical characterictic of same or similar technique effect simply change, all belong to the protection domain of the utility model technology.
As shown in Figure 1, a kind of mine down-hole mechanical air water expansion dedusting fan, comprise shell 1, aerosol expanding device, flow type pump with injection device 7, and in the present embodiment, described flow type pump with injection device 7 is horn-like.
Described aerosol expanding device comprises body 2, baffle plate 3, aerosol mixing tube 4, and this baffle plate 3 surrounds aerosol propagation chamber 10 with described body 2, and described aerosol mixing tube 4 is connected with this aerosol propagation chamber 10; The port of export of described shell 1 is equipped with filter screen 8, on described baffle plate 3, nozzle 5 is arranged, and this nozzle 5 is a plurality of, is regularly arranged.
One end of this baffle plate 3 and the joining place of described body 2 are cannelure 6, and described aerosol propagation chamber 10 is metal high-speed eddy structure.The port of export of described shell 1 is equipped with blow-off pipe 9, and this blow-off pipe 9 is near the inboard of filter screen 8.
Expansion the ejection at a high speed forward of the spray of the annular from this device groove rapidly after mixing battery 4 enters aerosol propagation chamber 10 when compressed air and dust-proof water, thereby form in the wings powerful negative pressuren zone: simultaneously, the high pressure dust-proof water sprays at a high speed to wind direction through nozzle 5, form the high-pressure water jet negative pressuren zone, two kinds of negative pressure stacks are by the distinguished and admirable suction of dust at flow type pump with injection device 7 rears, the high speed of cannelure 6 ejections is distinguished and admirable cuts into fine water-spray by the current expansion, and and the distinguished and admirable abundant mixing of dust-laden that sucks, thereby drench dust granules, adsorb and trickle to blow-off pipe 9 inflow ditches through filter screen 8, remnants in distinguished and admirable make moist, and due to deadweight, continuous decline falls dust granules, so far, complete whole dust removal process, reach the purpose of effective elimination dust.
