Description

Bag type dust collector

Technical Field

The utility model belongs to the technical field of dust removal equipment, and particularly relates to a bag type dust collector.

Background

The bag type dust collector is a common dust collecting device which uses a fiber woven bag as a filter layer and is used for filtering industrial dust-containing gas. The bag type dust collector is usually in an external filtering type negative pressure dust collection mode, and the dust collector has the advantages of good dust collection effect, safety, reliability and convenience in maintenance. But the dust on the inner wall of the ash bucket at the bottom of the bag type dust collector is difficult to clean when in use.

The patent grant publication No. CN210097183U of China discloses a pulse bag type dust collector, which comprises a dust collecting box body and a dust hopper fixedly connected with the bottom, wherein a supporting plate is arranged on the periphery of the outer part of the dust hopper, a vibrating device is arranged on the supporting plate, and the vibrating device shakes dust in the dust hopper by impacting the outer wall of the dust hopper. The bag type dust collector shakes dust piles in the dust hopper through an external vibrating device, and has a certain dust removing effect. However, the vibration device is only arranged on one side of the outer wall of the ash bucket, the overall stress of the ash bucket is uneven in the vibration process, and the ash removing effect on one side far away from the vibration device can be obviously reduced. In addition, the long-term mechanical vibration ash bucket shell can damage the ash bucket, and the air tightness of dust removing equipment is affected.

The patent grant publication No. CN218249074U of China discloses a pulse bag type dust collector, the top wall of the dust collector is provided with a hot air pipe, the hot air pipe extends into an ash bucket, the bottom of the hot air pipe is provided with a rotating pipe, the rotating pipe is connected with a rotating shaft, and scraping blades are arranged on the side face of the rotating shaft. The scraping blade is driven to rotate through the rotation of the rotating shaft, and dust on the inner wall of the ash bucket is scraped and crushed. The ash removal back-blowing mouth air injection arm of the pulse bag type dust collector is independent from the hot air pipe, and the rotation of the hot air pipe, the rotating shaft and the scraping blade requires an additional hot air source, so that the energy consumption of equipment is increased. In addition, the scraping blade is positioned at the ash cleaning opening of the ash bucket in the horizontal direction and faces large dust with strong adhesion, and when the scraping blade is not thoroughly broken, the scraping blade can block the discharge of the dust.
