ABSTRACT:
A rotary filter has a pressure vessel and a rotor from which a plurality of filter cells are suspended from outer portions of the rotor so that they clear a conveyor located proximal to the axis of rotation and upon which the filter cake is removed. Conduits are connected to the filter cells from a single distribution head for initially evacuating the cells in the filter stage and thereafter pressurizing the cells to dislodge the filter cake while the vessel remains under pressure. The filter cells can have the filter surfaces extending generally in axial planes or in axially spaced relationship in planes wherein a plurality of angularly spaced filters extend generally radially from respective filtrate conduits running axially along the outer part of the rotor.
