Abstract

The utility model relates to a dust setting pocket of a dust collector. The dust setting pocket is arranged in a dust collector body and comprises an internal bag core and external bag bodies surrounding the internal bag core; and the external bag bodies are folded and wind the periphery of the internal bag core. Because the external bag bodies re folded and wind the periphery of the internal bag core, the bag bodies are supported open by to be filtered wind during ventilation and filtering; and a filtering area acquired is greatly larger than a filtering area got by the present cylindrical filtering bag, thereby providing better filtering effect.

Description

Dust-collecting bag for dust collector

Technical field

The utility model relates to a kind of dust arrester of dust catcher, and the dust settling pocket of filtration treatment is carried out in especially a kind of dust catcher inside that is arranged on for the air with dust to sucking.

Background technology

The existing dust settling pocket that is arranged on dust catcher inside mostly is cylindrical structure, and after the air with dust sucked from air inlet entered dust settling pocket, dust was intercepted by bag, falls into bag, and the air after purification is discharged from from air outlet again.Yet under the prerequisite of identical filter area, the cylindrical shape filter bag must occupy larger space.Therefore the dust catcher producer just need to make awkward selection between small product size increase and poor filtration effect.

Summary of the invention

The purpose of this utility model is that the area that takes up room existed for existing cylindrical shape dust settling pocket is large, and the deficiency that efficiency of dust collection is low, be provided at the novel dust removing bag that can obtain larger filter bag area under the same space area.

The technical solution of the utility model is: a kind of dust settling pocket of dust catcher, be arranged on the internal body of dust catcher, and comprise an inner bag core and surround the outer bag of inner bag core, described outer bag is looped around inner bag core periphery for folding.

The beneficial effects of the utility model are: because the outer bag of dust settling pocket is looped around inner bag core periphery for folding, therefore when ventilation filter, wind to be filtered struts outer bag, and the filter dirt area obtained just is far longer than existing drum type brake filter bag, thereby obtains better filter effect.

The accompanying drawing explanation

Fig. 1 is the structural representation of the dust settling pocket of the utility model specific embodiment;

Fig. 2 is the dust settling pocket sectional structure schematic diagram of the utility model specific embodiment.

The specific embodiment

Specific embodiment of the utility model as shown in Figure 1 to Figure 2, a kind of dust-collecting bag for dust collector, comprise an inner bag core 1 and the outer bag 2 that surrounds the inner bag core, described outer bag 2 is looped around inner bag core 1 periphery for folding.

During use, after with the air inlet of the air self-dust-suction device of dust, entering, pass in dust settling pocket, wind-force makes dust settling pocket air-blowing in certain limit, obtain larger dedusting area, dust is attracted on outer bag, is passed in other evolution devices again and further purifies through preliminary clean wind, finally be excluded, the dust in dust settling pocket is collected into unified processing the in dust bucket.

Claims (1)

1. dust-collecting bag for dust collector, be arranged on the internal body of dust catcher, it is characterized in that: comprise an inner bag core and surround the outer bag of inner bag core, described outer bag is looped around inner bag core periphery for folding.
