Abstract
The utility model discloses a foam dust-collecting device for a coal mine. The foam dust-collecting device comprises a liquid storage tank (1) and a mobile fixed rack (6), wherein a foaming agent filling port (2) is formed on the top of the liquid storage tank (1); a fixed plug pin (7) is arranged at the bottom of the mobile fixed rack (6); a mixed foam maker (8) is arranged on the side wall of the liquid storage tank (1) and connected with an air inlet pipe (4), a water inlet pipe (5) and a high-pressure rubber pipe (9), which are fixed on the outer wall of the liquid storage tank (1); and regulating valves (3) are arranged on the air inlet pipe (4) and the water inlet pipe (5). The foam dust-collecting device for the coal mine is easy to install and operate, and convenient to transport, assemble and disassemble. The foam dust-collecting device is a mechanical foam dust fall device, has high safety factors and is good in dust fall effect. The fall efficiency of full dust and respirable dust is over 80 percent.
Description
Technical field
The utility model relates to a kind of foam dust-removing device, is specifically related to a kind of colliery and uses the foam dust-removing device.
Background technology
Mine dust not only can cause pneumoconiosis and bring serious harm for miner's physical and mental health, and when gas explosion takes place, might cause coal-dust explosion, causes the generation of weight, serious accident, brings huge disaster and loss to enterprise.Therefore, control effectively and reduce dust concentration, stop dust explosion accident, promoting mine safety production, ensureing that miner's physical and mental health is significant.The dedusting technology that extensively adopts now has coal-bed flooding, atomizing de-dusting, dedusting fan dedusting, chemical dedusting, dust removal by ventilation etc.; These have all played certain function in the process of control dust; But these dust-settling technologies are low to the capturing efficiency of respiratory powder; And water consumption is big, causes construction inconvenient.
Foam depositing dust efficient is high, water consumption is little, application site is extensive; Can administer dust disaster under the coal mine effectively; Its dust removal mechanism is: foaming agent mixes with water in proportion, when foam solution is ejected in the dust laden air, forms a large amount of foam particles; Its gross area and cumulative volume are very big, increase the contact area and the adhesive power of spray film and grit greatly.But most existing foam device for reducing dust still exist in the down-hole problems such as difficult installation, complicated operation, practical application property difference.
The utility model content
The technical problem that the utility model will solve provides a kind of simple in structure, depositing dust efficient height, and the foam dust-removing device is used in the colliery that can install in the down-hole quickly and easily, operate and use.
For solving the problems of the technologies described above; The foam dust-removing device is used in a kind of colliery of the utility model; Comprise that the top is provided with the fluid reservoir of blowing agent dress liquid mouth and the portable fixed mount that the bottom is provided with Fixed latches; It is characterized in that: the mixed foaming device is arranged on the sidewall of fluid reservoir, and the mixed foaming device is connected with blast pipe, water inlet pipe and the high-pressure rubber pipe that is fixed on the fluid reservoir outer wall, and said blast pipe and water inlet pipe are provided with control valve.
Compared with prior art, the beneficial effect that the utlity model has is:
1, the utility model is provided with portable fixed mount, and dust arrester can advance flexible changing position with working face extraction, does not influence working surface production, and fitting operation is simple, carrying, assembling, convenient disassembly.
2, the utility model need not electricity consumption, is mechanical type foam device for reducing dust, needn't carry out explosion-proof processing, has than high safety factor.
3, the utility model is reasonable in design, and dust-laying effect is good, the efficient of the depositing dust of full dirt and respirable dust is reached more than 80%, and be 2 times of common atomizing de-dusting efficient.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of a kind of colliery of the utility model with the foam dust-removing device.
The specific embodiment
As shown in Figure 1; The foam dust-removing device is used in a kind of colliery; Comprise that the top is provided with the fluid reservoir 1 of blowing agent dress liquid mouth 2 and the portable fixed mount 6 that the bottom is provided with Fixed latches 7; Mixed foaming device 8 is arranged on the sidewall of fluid reservoir 1, and mixed foaming device 8 is connected with blast pipe 4, water inlet pipe 5 and the high-pressure rubber pipe 9 that is fixed on fluid reservoir 1 outer wall, and said blast pipe 4 is provided with control valve 3 with water inlet pipe 5.
Portable fixed mount 6 is fixed on the belt conveyer through Fixed latches 7; Connect blast pipe 4, water inlet pipe 5 and high-pressure rubber pipe 9 on the mixed foaming device 8; High-pressure blast in the blast pipe 4 and water inlet pipe 5 inner high voltage water are the mobile power that provides of making bubble and foam, fine setting control valve 3, and quantitative water, gas and blowing agent produce the foam of certain volume in mixed foaming device 8; After follow-up pressure wind effect is by the shower nozzle ejection, form foam stream and cover dust, suppress the diffusion of dust.Meanwhile fly away aerial foam and form a large amount of foam particle crowds again; Its cumulative volume and the gross area are very big; Increased contact surface and adhesive power with grit greatly, and acted on dust, thereby effectively reduced dust concentration through modes such as holding back, collide, spread, stick.Foam falls and falls behind in the tunnel lower surface and evenly disperse, and covers on the base plate in tunnel and has avoided reentrainment of dust again effectively.
Claims (1)
1. the foam dust-removing device is used in a colliery; Comprise that the top is provided with the fluid reservoir (1) of blowing agent dress liquid mouth (2) and the portable fixed mount (6) that the bottom is provided with Fixed latches (7); It is characterized in that: mixed foaming device (8) is arranged on the sidewall of fluid reservoir (1); Mixed foaming device (8) is connected with blast pipe (4), water inlet pipe (5) and the high-pressure rubber pipe (9) that is fixed on fluid reservoir (1) outer wall, and said blast pipe (4) and water inlet pipe (5) are provided with control valve (3).
