Description

Technical Field

[0001] The utility model relates to the technical field of bag dust collectors, in particular to a low-emission bag dust collector. Background Art

[0002] Bag filter is a common environmental dust removal equipment in industrial production. The waste gas generated by the factory is filtered out by the bag filter for the next operation or discharged into the atmosphere. The dust-containing gas enters the air intake pipe at the bottom of the dust collector, and the coarse dust will fall into the ash hopper. The remaining fine dust particles enter the filter bag chamber with the gas. Due to the inertia, diffusion, barrier, hooking, static electricity and other effects of the filter material fibers and fabrics, the dust is retained in the filter bag. The purified gas escapes from the bag and is discharged through the exhaust pipe.

[0003] A known authorized invention (publication number: CN116764341A) discloses a low-emission bag dust collector, including a dust collector body, a filter bag is arranged inside the dust collector body, a feed pipe is opened on one side of the filter bag, a pretreatment device is arranged outside the dust collector body, the pretreatment device includes a pretreatment box, a vertical partition, a plurality of transverse partitions and a filter screen, a slag discharge port is arranged at the bottom end of the pretreatment box, a slag discharge port is provided with a slag discharge mechanism, and the feed pipe is connected to the pretreatment box. The low-emission bag dust collector buffers the dust-containing gas through the pretreatment device, and the filter screen is used for filtering, so that coarse particles are filtered quickly, avoiding the coarse dust from impacting the filter bag, reducing the dust content of the gas entering the dust collector body, and achieving a better dust removal effect;

[0004] When the device is in use, although the dust-containing gas is buffered by the pre-treatment device and the filter is filtered to quickly filter the coarse particles, the coarse dust is prevented from impacting the filter bag, the dust content of the gas entering the dust collector body is reduced, and the dust removal effect is better. However, during long-term use, due to the lack of an effective anti-clogging structure, the filter is prone to clogging, resulting in a decrease in the dust removal effect. Therefore, we proposed a low-emission bag dust collector to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides a low-emission bag dust collector, which solves the problems raised in the above-mentioned background technology.

[0007] (II) Technical solution

[0008] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0009] The filter press has one hand holding the filter screen, the other hand holding the filter screen, the filter screen having a plurality of filter pockets, and a plurality of filter pockets are provided on the filter screen.

[0010] Furthermore, a plurality of inclined plates are fixedly connected to the left inner wall of the filter box and the other side of the partition.

[0011] Furthermore, a collecting box is movably connected to the filter box, and a sealing plate is fixedly connected to the front side of the collecting box.

[0012] Furthermore, the sealing plate is threadedly connected to the filter box via four bolts.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a low-emission bag dust collector with the following beneficial effects:

[0017] The utility model starts a driving motor to drive the circular plate to rotate. When the circular plate rotates for the first half of a circle, the circular plate drives the connecting rod to rotate. The connecting rod drives the connecting mesh plate downward through the hinged rod. The connecting mesh plate slides on the positioning rod and compresses the spring. The connecting mesh plate drives multiple inverted rods to move, so that the inverted rods are inserted into the corresponding filter holes to pour out the particles in the filter holes. When the circular plate rotates to the second half of a circle, the spring in a compressed state is reset. Under the action of the spring's own elastic force, the spring drives the connecting mesh plate to move upward, and the connecting mesh plate drives the inverted rod to move upward, so that the connecting inverted rod can move up and down reciprocatingly for cleaning, thereby preventing the filter holes from being blocked and improving the filtering effect.
