The dust-containing gas is conveyed by the fan into the dust collector. The large particles of dust are separated and fall directly into the ash hopper. The remaining light dust is evenly distributed with the airflow through the shunt baffle, and then filtered by a high-density filter bag. The filtered clean gas Drain into the atmosphere from the exhaust hood; as the filtering conditions progress, dust will accumulate on the surface of the filter bag, and when the dust accumulates to a certain amount, the dust will automatically fall off, and the dust on the remaining filter bag will be removed by the air pressure pulse cleaning device For cleaning, the dust falling into the ash hopper is discharged through the conveying system. DR-HK dust collector series, the production line can also be dusty when it is running. The cleaning process is based on the amount of dust in the dust collector, setting the timing time of the cleaning device and the dusting device, and it will automatically clean and automatically discharge the dust when the dust is discharged. The valve is automatically switched to prevent dust leakage, and the dust enters the storage tank by means of air conveying and other systems and is squeezed out.
