With the extension of filtration time, the dust on the filter bag keeps accumulating, and the resistance of the dust removal equipment keeps rising. When the resistance of the equipment rises to the set value, the control device is turned on and enters the cleaning state, and the air expands rapidly in the upper box in a very short time and flows into the filter bag, which makes the filter bag expand and deform to generate vibration. Under the action of reverse airflow scouring, the dust attached to the outer surface of the filter bag is stripped and falls into the dust accumulation bucket. After the dust removal is completed, the control device is closed, and the chamber returns to the normal filtering state.
