Vacuum drum filter equipment is mainly used for liquid waste treatment diatomaceous earth, hence called diatomaceous earth waste treatment device. The device is driven by the reducer filter continuous uniform rotation of the drum by a vacuum pump pressure difference formed by the filter drum within the dispenser, the flow through the filter material was filtered off with suction, the water in the feed solution was continuously sucked into the discharge or recycle tank; and solid materials (such as diatomaceous earth) is uniformly adsorbed on the outer surface of the drum forming a cake layer, when the layer reaches a certain thickness of the filter cake, through the discharge zone blade automatic feed, and the feed to the cutting blade position of the layer cake, the solid material was cut to take a continuous chute in the bag handle. This cycle, continuous suction filtration operation, the water discharge of waste residue and require separate treatment, to environmental protection, health requirements.
