Rotary Vacuum Filter.
Rotary Vacuum Filter
The most common types of continuous
vacuum filter is the rotary drum filter. A horizontal drum with a
slotted face turns at less than 2 RPM in an agitated slurry trough. A
filter medium, such as canvas, covers the face of drum, which is partly
submerged in the liquid. Under the slotted cylindrical face of the main
drum is a second, smaller drum with a solid surface. Between the two
drums are radial partitions dividing the annular space into separate
compartments, each connected by an internal pipe to one hole in the
rotating plate of the rotary valve Vacuum and air are alternately
applied to each compartment as the drum rotates. The set-up consists of
stainless steel drum moving in gunmetal brackets and is divided in 6
compartments, covered by a Stainless Steel mesh. A canvas filter is used
for filtration. The whole assembly is fitted with a SS trough in which a
agitator is provided. To make the unit a self-contained a slurry mixing
and feed arrangement, receiver tanks, vacuum pump, control panel are
provided.
