The mobile fume extraction unit uses the filter bag made of fiber fabric to filter dust to purify the dust-containing air flow. When the dust accumulates on the filter bag to a certain extent, the filter bag is sprayed and cleaned by means of compressed air in the form of pulses, so as to achieve the purpose of cleaning the filter bag. The dust cloth bag of the mobile fume extraction unit, under the suction of the fan, the dust-laden air enters the vacuum room box through the air inlet at the bottom of the lower box, the dust particles are blocked on the outer wall of the filter bag, and the air purified through the filter bag is discharged from the fan air outlet.

With the increase of dust particles on the surface of the filter bag, the resistance of the dust collector also increases accordingly, which gradually weakens the filtering capacity. When the resistance reaches a certain level, it needs to be cleaned. At this time, the pulse controller periodically sends out signals to open the electromagnetic pulse valve sequentially, so that the compressed air in the air bag passes through the pulse valve through the small hole on the injection pipe, and ejects a high-speed and high-pressure jet air flow into the filter bag, which is the filter bag. Rapid expansion, and then blowing the middle finger, the filter bag shrinks sharply again, so the expansion and contraction will shake off the dust accumulated on the outer wall of the filter bag to ensure that the filter bag is in good working condition. Since the cleaning process is carried out in sequence, and the dust-laden air is never cut off, the dust removal capacity remains basically unchanged during the working process of the dust collector. In order to meet the requirements of different working conditions, the pulse interval and pulse width of the pulse controller can be adjusted arbitrarily.
