Plate and Frame Filter Press.
Plate and Frame Filter Press
Pressure filters can apply a large
pressure differential across the septum to give economically rapid
filtration with viscous liquids or fine solids. The most common types of
pressure filters are filter press. A filter press contains a set of
plates designed to provide a series of chambers or compartments in which
solids may collect. The plates are covered with a filter medium such as
canvas cloth. Slurry is admitted to each compartment under pressure;
liquor passes through the canvas cloth and out a discharge pipe, leaving
a wet cake of solids behind. Plates and frames sit horizontally in a
metal rack, with cloth covering the face of each plate, and are squeezed
tightly together by a screw. Slurry enters at one end of the assembly
of plates and frame. It passes through a channel running lengthwise
through one corner of assembly. The set up consists of 7 plates and 6
frames. Frames are covered with filter cloth. Feed is fed by gear pump
at the top and filtrate collected at the bottom from each plate by
operating the cock. After removing Cake, washing and cleaning can be
done by water provided by overhead tank. Inlet & outlet pressures
are measured by pressure gauges. Rate of filtrate removals is measured
by calibrated tank provided.
