ABSTRACT:
An improved filter press for separating solids from liquid is provided. The press includes a plurality of filter plates which are suspended from overhead I-beams such that the plates may be removed either from the top of the press or from the sides of the press as desired. The filter plates are suspended from the I-beams by rollers which alternate in position for adjacent filter plates between engagement with the outside flanges and engagement with the inside flanges of the beams and, thus, allow larger rollers to be utilized. The filter press includes a press head for moving the individual filter plates into abutting relationship which is pivotally suspended from the I-beams such that the press head can assume the alignment of the filter plates when the press is closed. The press further includes a pair of vertically-arranged, independently-operable hydraulic closing rams for applying different closing pressures at the top and bottom of the filter plates to compensate for variations in plate stacking.
