Abstract
The utility model discloses a mining foam dust falling device which comprises a support (1), a liquid storage tank (2), a mixing foam maker (3) and an operation box (4). The mining foam dust falling device is characterized in that the support (1) is fixed on a belt conveyer (6) through a bolt (5), the liquid storage tank (2), the mixing foam maker (3) and the operation box (4) are combined integrally to be arranged on the support (1), a high-pressure rubber hose (7) is connected between the liquid storage tank (2) and the mixing foam maker (3), a high-pressure air pipe (8) and a high-pressure water pipe (9) are arranged on the operation box (4), and the high-pressure air pipe (8) and the high-pressure water pipe (9) are respectively provided with an adjusting valve (10) respectively. The mining foam dust falling device is easy to operate, high in safety coefficient and good in dust falling effect. When movement of the mining foam dust falling device is required, a user only needs to release the bolt (5), and flexible changing of positions on the belt conveyer along with backstopping and boosting of a working face can be achieved.
Description
Technical field
The utility model relates to a kind of device for reducing dust, relates in particular to a kind of mining foam device for reducing dust.
Background technology
In the Coal Production process, as boring, explosion, driving and coal mining activity, loading and transportation wait each link all can produce a large amount of mine dusts.Mine dust not only can cause pneumoconiosis and bring serious harm for miner's physical and mental health, and might cause coal-dust explosion when gas explosion takes place, and causes the generation of weight, serious accident, brings huge disaster and loss to enterprise.
For administering mine dust disaster under the coal mine effectively, the dedusting technology of each mine employing has coal-bed flooding, atomizing de-dusting, foam depositing dust, dedusting fan dedusting, chemical dedusting, dust removal by ventilation etc. at present, particularly atomizing de-dusting technology and foam dust-settling technology use more, but existing atomizing de-dusting DeGrain, and water supply volume causes the working environment humidity greatly, though existing foam device for reducing dust dust-laying effect is better than atomizing de-dusting effect, move problems such as difficulty, complicated operation, practical application difference in the down-hole but still exist.
The utility model content
The technical problems to be solved in the utility model provides a kind of mining foam device for reducing dust flexible, simple to operate, that safety factor is high, dust-laying effect is good that moves.
For solving the problems of the technologies described above, a kind of mining foam device for reducing dust of the present utility model, comprise support, fluid reservoir, mixed foaming device and control box, it is characterized in that: support is fixed on the belt conveyer by latch, fluid reservoir, mixed foaming device and control box are combined into one and place on the support, be connected with high-pressure rubber pipe between fluid reservoir and the mixed foaming device, control box is provided with high-pressure blast pipeline and high-pressure water pipeline, and high-pressure blast pipeline and high-pressure water pipeline are provided with control valve.
Compared with prior art, the beneficial effect that the utlity model has is:
1, is fixed on the belt conveyer by latch owing to support of the present utility model, flow container, mixed foaming device and control box are combined into one and place on the support, when needs move this device, only need unclamp latch, can realize along with working face extraction advances flexible changing position on belt conveyer.
2, be connected with high-pressure rubber pipe between fluid reservoir of the present utility model and the mixed foaming device, control box is provided with high-pressure blast pipeline and high-pressure water pipeline, high-pressure blast pipeline and high-pressure water pipeline are provided with control valve, in use, only need adjust control valve, just can make foam cover the full face mine dust in tunnel fully, thereby suppress the diffusion of mine dust, therefore simple to operate.
3, the mining foam device for reducing dust of the utility model need not electricity consumption, employing be mechanical type foam depositing dust, have higher safety factor.
When 4, the utility model was worked, the foam of ejection can cover the full face mine dust in tunnel fully, suppressed the diffusion of mine dust and reduced mine dust density, can evenly disperse in the tunnel lower surface after the foam landing, cover on the base plate in tunnel, avoid reentrainment of dust again effectively, dust-laying effect is good.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of mining foam device for reducing dust of the utility model.
The specific embodiment
As shown in Figure 1, a kind of mining foam device for reducing dust, comprise support 1, fluid reservoir 2, mixed foaming device 3 and control box 4, support 1 is fixed on the belt conveyer 6 by latch 5, fluid reservoir 2, mixed foaming device 3 and control box 4 are combined into one and place on the support 1, be connected with high-pressure rubber pipe 7 between fluid reservoir 2 and the mixed foaming device 3, control box 4 is provided with high-pressure blast pipeline 8 and high-pressure water pipeline 9, and high-pressure blast pipeline 8 and high-pressure water pipeline 9 are provided with control valve 10.
During use, the blowing agent that liquid storage is irritated in 2 is pressed in the mixed foaming device 3 through flow meter by high-pressure rubber pipe 7, water under high pressure flows in the mixed foaming device 3 through water ga(u)ge by the high-pressure water pipeline 9 on the control box 4, high-pressure blast enters in the mixed foaming device 3 through the wind flow meter by the high-pressure blast pipeline 8 on the control box 4, wind and quantitative water like this, blowing agent has formed gas in mixed foaming device 3, the common situation that exists of gas-liquid two-phase liquid, two kinds of fluids blow mutually and hit, collide, stir, thereby produce the foam of certain volume, after the shower nozzle ejection, adjust control valve 10 more accurately, make foam can cover the full face mine dust in tunnel fully, thereby suppress the diffusion of mine dust.
Meanwhile fly away aerial foam and form a large amount of foam particle groups again, its cumulative volume and the gross area are very big, increase contact surface and adhesive power with grit greatly, and act on mine dust by modes such as holding back, collide, spread, stick, thereby effectively reduce mine dust density.
In addition, can evenly disperse in the tunnel lower surface after the foam landing, cover on the base plate in tunnel, avoid reentrainment of dust again effectively.
When needs move this device, only need unclamp latch, can realize along with working face extraction advances flexible changing position on belt conveyer.
