Abstract

The utility model relates to a dust collecting wholly sealed material guiding trough, which is used in the coal conveying system of a power station, a coal mine and the like. The lower part of a material guiding trough side plate and the upper part of a cushioning sealing plate are spliced with each other and sealed, and an auxiliary sealing skirt plate is arranged between the two ends of a belt, so as to realize the double-sealing purpose; the top plate behind the material discharging point of the material guiding trough is lengthened to realize the capacity expansion; partition are arranged at different levels of the material guiding trough to induce air to move in a snake shape; a dust collection damping unit is arranged in the middle of each partition; a fan is arranged at the tail part of the material guiding trough so as to completely pump out low-speed induction air with a small quantity of dust; and the induction air pumped out blows into the middle section of a coal dropping pipe of the previous level. The sealing performance of the utility model is greatly improved, so the utility model can be better applied under poor working conditions with high fall and the like; the dust collection is realized through the dust collection damping unit in the material guiding trough; the induction air is transmitted to the coal dropping pipe of the previous level; the induction air which flows into the material guiding trough is reduced; and the improvement of the system greatly reduces the dust generated in the material conveying process, improves the environment of the coal conveying system, and prolongs the service life of the equipment.

Description

The hermetically sealed deflector chute of control of dust

Affiliated technical field

The utility model relates to and a kind ofly is used for a kind of compound type that field such as power station, colliery coal handling systems cooperate three-dimensional dispersed material afflux coal spouts (chute) to use, has a hermetically sealed deflector chute of control of dust of dust collection effect simultaneously.

Background technology

Deflector chute is to be used for the transportation of discharging point control solid accumulation in the loose unpacked material transport process, to prevent that material from leaking and control the device that dust is raised outward, place the top of adhesive tape, the exit skirt structure that tradition is used or the deflector chute of rectangular configuration are subjected to the impact wear of material and the influence of induced air, and sealing effectiveness is poor; Deflector chute distance from bottom adhesive tape 30-50mm, rubber anti-overflow skirtboard or waste and old adhesive tape are installed in the deflector chute both sides, guarantee that the deflector chute both sides are with the sealing between the adhesive tape, but anti-overflow skirtboard or waste and old adhesive tape are in use often lacked service life, in the adhesive tape course of conveying, the glue surface with glue is produced wearing and tearing simultaneously, reduce adhesive tape service life, sealing effectiveness is bad to be prone to big dust; Simultaneously, because coal handling system in actual use, different transfer point discharging point adhesive tapes are difficult to reach complete contact condition with the carrying roller contact portion, particularly at the transhipment website of high drop, the influence that impacted by bulk materials during the adhesive tape operation, the adhesive tape shake is bigger, adhesive tape is difficult to reach sealing fully with deflector chute cushion seal plate, cause dust to reveal, be prone to big dust at transfer point, at present, the dirt that subtracts in the deflector chute be designed to dispose electric precipitation or flat bag filter, invest bigger, the maintenance cost height.

Summary of the invention

For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of control of dust hermetically sealed deflector chute, by sealing system multi-stage sealed with between the adhesive tape, dilatation and collecting unit of dust is installed, at the deflector chute afterbody induced draft fan is installed in deflector chute simultaneously improves dust and reveals and raise and suppresses the purpose that dust, reduction enter the induced air of deflector chute outward to reach.

For achieving the above object, the technical solution of the utility model is: the top encapsulation of steel structure framework has top board, the top splicing and the sealing of the bottom of deflector chute side plate and cushion seal plate are connected together, the deflector chute side plate is connected on the steel structure framework, be connected with top board and seal, the cushion seal plate is by the supports support that is connected on the steel structure framework, be installed in the bottom splicing and the sealing of adhesive tape two ends, carrying roller group top on the steel structure framework and cushion seal plate, it is characterized in that: secondary sealing skirtboard is installed respectively between the bottom of deflector chute side plate and end, adhesive tape two ends, by with the cushion seal plate, the positive press contacts of the driving surface of adhesive tape realizes primary seal, and the deflector chute side plate is realized secondary seal with the non-working surface contact of adhesive tape.

Feature of the present utility model also is the part behind the deflector chute discharging point, by being increased, top board realizes dilatation and increases multiple tracks cutting off, in dilatation section deflector chute, in the middle of per two adjacent partitions the control of dust damping unit is installed, induced air is progressively decayed at wind speed by wherein the time, and dust is progressively absorbed by the control of dust damping unit and falls on the adhesive tape simultaneously.

The utility model is installed induced draft fan at the deflector chute afterbody, and last induced air is all extracted out, and the induced air of extraction blows into the stage casing part of upper class coal spout.

Cushion seal plate described in the utility model, deflector chute side plate adopt casting type polyurethane elastomer to make, and secondary sealing skirtboard adopts antifriction rubber or polyurethane elastomer to make.

Control of dust damping unit described in the utility model can be the plastic flagstone with holes of vertical intensive layout, also can be the multi-angular rubber adhesive tape of vertical hanging.

The utility model compared with prior art, the sealing property of deflector chute improves greatly, can adapt to bad working environments conditions such as high drop better, cancel flat bag-type dust equipment, realize gathering dust in deflector chute, the residue induced air is sent to the upper class coal spout again, reduce the induced air that enters in the deflector chute, the improvement of series greatly reduces the generation of dust in the material conveying process, can effectively improve the coal handling system environment, improves the service life of equipment.
