Abstract
The invention belongs to the technical field of dust removers, and particularly discloses a bag dust collector with a self-dust-cleaning function. The self-dust-cleaning function of a filter bag is achieved by adopting the filter bag with a smooth surface and an air inlet in the tangential air inlet direction in the bag dust collector. In addition, a double-layer dust filtering device is adopted, the filtering area of the dust collector is greatly increased, the problem that the filtering area is reduced as the filter bag with the smooth surface is adopted is solved, and the dust collecting effect is achieved by means of air circulation between inside and outside filter bag bodies. The bag dust collector has the advantages of being low in cost, capable of working continuously and suitable for movable dust collection equipment, and having few fault points.
Description
Technical field
The invention belongs to sack cleaner technical field, specifically disclose a kind of sack cleaner having from deashing function.
Background technology
Existing sack cleaner generally comprises dedusting chamber, ash silo, dust filtration device, dedusting driver and deashing device, dedusting chamber is arranged at ash silo top and bottom and ash silo and interconnects, dedusting driver and deashing device are arranged at cavity top, dedusting chamber, and dust filtration device is arranged in dedusting chamber. The top in dedusting chamber offers air outlet, on the sidepiece cavity of dedusting chamber or ash silo, offers air inlet. Dusty gas enters dedusting chamber from air inlet under the effect of dedusting driver, and after dust filtration device filters, dust is trapped on filter bag, and clean gas enters atmosphere from air outlet. In the time that the dust on dust filtration device increases gradually, can have influence on dust collection effect and the dust-collecting efficiency of deduster, the effect of deashing device is exactly that dust on dust filtration device is removed, and realizes the gather dust regeneration of ability of dust filtration device.
Industrial general employing electromagnetic pulse blowing device is realized the deashing function of deduster, this deashing device has advantages of controls flexible, technical maturity, but because needs use multiple magnetic valves and nozzle correspondingly, and compressed gas transmission pipeline need to be set, cost is higher, trouble point is many, is not suitable for portable cleaner.

Adopt double-deck dust filtration device, not only greatly increased filter area, the filter area having solved because adopting shiny surface filter cloth to bring reduces problem, and the also circulation between inside and outside filter bag by gas, has improved filter dirt effect.
Preferably, the inside in described dedusting chamber is provided with stiffener, and the position of stiffener is the air intake direction to air inlet substantially just. On dedusting cavity shell, stiffener is set, avoids the sharp object in dusty gas directly to impact dedusting housing and dust filtration device, extended service life of equipment.
Preferably, be also provided with universal wheel below described ash silo, facilitate the movement of deduster, what maximized performance the present invention proposed has the strong point from the sack cleaner of deashing function.
The technique effect that the present invention is useful:
1, because air inlet and the shiny surface filter cloth by employing with tangential air intake direction have been realized from deashing function, deduster provided by the invention saves the deashing device of reducible existing equipment, reduce cost, reduced trouble point, can continuous operation and be applicable to movable dust removal equipment.
2, adopt double-deck dust filtration device, not only greatly increased filter area, the filter area having solved because adopting shiny surface filter cloth to bring reduces problem, and the also circulation between inside and outside filter bag by gas, has improved filter dirt effect.
3, on dedusting cavity shell, stiffener is set, avoids the sharp object in dusty gas directly to impact dedusting housing and dust filtration device, extended service life.
Below in conjunction with Figure of description and specific embodiment to provided by the invention have from the sack cleaner of deashing function be specifically introduced.
