ROTARY VACUUM FILTER APPARATUS

Product Description

Specification:

ROTARY VACUUM FILTER APPARATUS

The most common types of continuousvacuum filter are the rotary drum filter. A horizontal drum with a slotted faceturns at less than 2 rpm in an agitated slurry trough. A filter medium, such ascanvas, covers the face of drum, which is partly submerged in the liquid. Underthe slotted cylindrical face of the main drum is a second, smaller drum with asolid surface.

Between the two drums are radialpartitions dividing the annular space into separate compartments, eachconnected by an internal pipe to one hole in the rotating plate of the rotaryvalve vacuum and air are alternately applied to each compartment as the drumrotates. The set-up consists of stainless steel drum moving in gunmetalbrackets and is divided in 6 compartments, covered by a stainless steel mesh.

A canvas filter is used forfiltration. The whole assembly is fitted with a ss trough in which a agitatoris provided. To make the unit a self-contained a slurry mixing and feedarrangement, receiver tanks, vacuum pump, control panel are provided.
