Description

Dust collector

Technical Field

The invention relates to a cleaning device, in particular to a dust collector.

Background

The dust collector drives the blades to rotate at a high speed by using the motor, and generates air negative pressure in the sealed shell to absorb dust. The existing industrial dust collector mainly depends on a filter cloth bag arranged in the industrial dust collector to filter and remove dust, and filtered air is exhausted by a vacuum pump. However, in the case of long-term use of the cloth bag type dust collector, the cloth bag is quickly full of dust, so that the cloth bag is blocked, and the dust collection effect is affected. In order to solve the problem, the traditional method adopts two modes of manual dust vibration and pulse cleaning.

The manual dust vibration is to vibrate the dust accumulated on the cloth bag into the dust collection barrel. The manual dust vibration has the problems of high labor intensity, low cleaning efficiency and unsatisfactory cleaning effect.
