Description
Technical field
The utility model belongs to dust collector technical field, is specifically related to the structural development of the dust collector of a kind of particulate dust in belt transmission transport process.
Background technology
In the industrial production, method for conveying solid material mostly adopts multi-segment belt-conveying, and be provided with a transfer point at the joining place of each section belt, this transfer point includes one and is located at logistics guide groove between epimere belt and hypomere belt, this logistics guide groove top is provided with an inlet point, by upper end belt, material is sent in deflector chute, material can produce large stroke dust when falling, contaminated environment, the scheme of this kind of dust of current domestic process roughly has two kinds, one is traditional dedusting method and bag-type dust, multi-tube dusting, electrostatic precipitation, water excitation type dust exhaustor etc., above-mentioned traditional dedusting method is in industry park plan, all there is power consumption high, dust removing effects is poor, maintenance cost is high, produce the drawback that secondary emission is polluted.Another kind is novel Unpowered dust collector, and it mainly uses physics siphon principle, energy conservation principle etc., allows dust actv. circulation in seal channel make the dust energy decline hypomere belt that falls back complete dedusting.
Through retrieval Chinese patent: Unpowered dust collector disclosed in ZL200820013183.0 is a kind of is set up the dust exhaustor that secondary delays pressure chamber; Another kind of ZL200820218038 is a kind of dust exhaustor setting up convolution decompression chamber.Although these two kinds of dust exhaustors have: not electricity consumption, need not land occupation in addition, just utilize travelling belt upper end space, a large amount of material, non-secondary pollution can be saved, comprise the hot-tempered sound pollution of high shellfish, thoroughly realize the advantages such as the non-maintaining operation of dusting equipment, but these two kinds of power-free dust-removing equipment no matter add convolution decompression chamber or secondary delays pressure chamber measure, all be equipment integrating with control of dust pumping chamber, dedusting method is a road dedusting, dedusting is just carried out in control of dust pumping chamber, and the enforcement of various ancillary methods is all the service of control of dust pumping chamber.The dedusting method of this pressure charged makes the dust concentration of control of dust pumping chamber high, can reach detonation degree completely.If this kind of equipment is except coal dust, especially power plant, coal coal yard is in the open stacked natively has dieseling, will detonation when coal runs into the coal dust of high concentration in belt transport, room structure only single in addition cannot reach national dedusting technology standard-required, so this kind of equipment imperfection.
The simple principle of these two kinds of dust exhaustors and imperfection place are added brief analysis below, a kind of is set up the Unpowered dust collector that secondary delays pressure chamber structure.Because material proceeds in the process of another section of belt by one section of belt in sealed states, because drop reason produces enormous impact power, but also be the movement of falling object so produce powerful negative pressure, and material impact is malleation to another belt, because the huge dust produced in impact process just, dust is ceaselessly circulated at material discharging groove and control of dust pumping chamber (interior installation dust-break curtain), completes main body dedusting.But powerful impulsive force and the dust of high concentration cause quite a few dust to go out dust-break curtain, this part dust energy is still very large.If increase dust-break curtain thickness to strengthen dust-break effect, then can stop that material runs, and results in blockage, and affects equipment normal operation; Delay the pressure chamber structure that communicates with control of dust supercharging again make the part dust going out dust-break curtain again get back to secondary to delay in pressure chamber and circulate so need to set up secondary.Another is the Unpowered dust collector setting up convolution decompression chamber structure, this is arrange multiple right angle that is not more than with the deflector shield being folded to angle in convolution decompression chamber, its objective is and makes the further exhaustion of dust kinetic energy to form multiple chicane in decompression chamber around guide plate.But really not so in real-world operation, first can not be too low bottom deflection plate, must be arranged on and can meet the height that belt is fully loaded with transport inventory, otherwise will cause putty phenomenon, impact runs.Because belt top catching groove has occupied the space of a part of transported material, when inventory is slightly little or normal conveying time, just there is very large space with material top bottom deflection plate.At this moment, when material drops to hypomere belt machine end along material deflector chute, the explosion impact energy of dust is very large, speed is also very fast, the dust-break curtain of convolution decompression chamber is flung along belt direction of travel, part dust is up along dust-break curtain, another part dust reverse reflex, up along deflection plate return flow line, to bump against at top, decompression chamber and follow-up powder dirt constantly pours in decompression chamber along the up dust of the up dust of dust-break curtain and deflection plate return flow line like this, instant decompression room is completely full by high concentrate dust punching, and dust concentration is increasing.Dust is divided into two strands like this completely, and one is up along dust-break curtain, and another stock is then up along deflection plate return flow line.Such script is wanted to utilize deflection plate return flow line to make dust descending, make its with by dust-break curtain effect and up dust forms order cycle, thus the conception realizing effectively falling energy has become impossible.In other words decompression chamber of circling round does not have Efficient Cycle at all and falls and can act on.In addition, because convolution decompression chamber is close to control of dust pumping chamber, the powerful negative pressure in control of dust pumping chamber sucks back major part the dust in high density convolution decompression chamber again.Another part dust also will go out dust-break curtain, and this setting can not accomplish complete dedusting as seen.
