ROTARY VACUUM FILTER APPARATUS

Product Description

The most common types ofcontinuous vacuum filter are the rotary drum filter. A horizontal drum with aslotted face turns at less than 2 rpm in an agitated slurry trough. A filtermedium, such as canvas, covers the face of drum, which is partly submerged inthe liquid. Under the slotted cylindrical face of the main drum is a second,smaller drum with a solid 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.
