Gravity Drum Paper Filter

The dirty liquid flows into the interior of the drum of the drum - type filter. The drum rotates slowly under the drive of the motor, with a paper - tape wound around its outer surface. Under the action of gravity, the liquid passes through the paper - tape and flows downward, while the impurities are intercepted on the paper - tape to form a filter cake. When the filter cake thickens or the filtrate flow rate decreases, it indicates that the filtration performance of the paper - tape declines. At this time, the liquid - level sensor monitors that the liquid level rises to the set height due to the blockage of the filter cake, and then triggers the transportation of the new paper - tape and the discharge of the used paper - tape to maintain the filtration work. The clean liquid flows into the water tank below for subsequent use.
