Negative Pressure Drum Dust Collector

The large fan starts a large flow of exhaust, and its air inlet pipe generates negative pressure in the drum and transmits the negative pressure to the vacuum cleaner box. Under the action of this negative pressure, the dusty air in the workshop is sucked through the three air inlet ducts on the upper part of the box; after the dusty air enters the vacuum cleaner box, it moves along the negative pressure path toward the inlet of the large fan. When it moves to the outer filter layer of the drum, it is blocked on its surface. At this time, the suction device for separating dust starts the high-pressure centrifugal fan and at the same time starts the pneumatic actuator. The pneumatic actuator drives the suction port close to the filter layer to suck the attached dust and sends it to the collection device through the pipeline.
