Background
An industrial dust collector is also called an industrial dust collector, and is used for collecting and sucking waste medium particles, dust, smoke, oil water and the like generated in the production, operation and transportation processes. The working principle of the industrial dust collector is as follows: the air inside the machine is drawn off by means of a fan or an air pump, which creates a pressure difference between the inside and the outside of the machine, the so-called negative pressure, the higher the negative pressure, the stronger the suction.
The invention provides an industrial dust collector, which is provided with a pulse valve, wherein the pulse valve is opened at regular time, compressed air is sprayed onto a filter bag through each eyelet of a spray pipe, redundant dust on the filter bag is cleaned, the filter bag keeps smooth ventilation, but the distance between the dust and the filter bag is closer and closer when more and more dust is cleaned at the bottom of the dust collector which is not cleaned in time after the dust collector works for a long time, the dust at the top can be sucked onto the surface of the filter bag when the dust collector works at regular time, and the dust removal effect of the dust collector can be reduced before an electromagnetic pulse valve does not work.
