ABSTRACT:
A self supporting filter plate assembly having two opposed screen sections with inwardly shaped deformations which engage each other to maintain a planar surface of the screen sections at a predetermined spacing. The screen sections releasably engage each other. Inwardly directed retaining pins of an exterior frame removably support the screen sections in place within the frame. Each of the screen sections include edges which are bent at 90.degree. with respect to a central planar portion of each screen. The edge portions of the two screen sections interengage with each other by a projection in an inner surface of an edge portion of one screen section engaging with a recess extending from an outer surface of an edge portion of the other screen section. In addition, spaced openings in the edge portions, on opposed side edges of both screen sections, interengage with the inwardly directed retaining pins extending from an inner surface of opposed sides of the frame. Each of the screen sections also include a plurality of spaced dimples having a diameter of approximately one inch and a depth of approximately 5/16 of an inch. The dimples of each screen section are positioned opposite to one another so that upon assembly of the two screen sections within the frame, the dimples contact each other when the screen sections are forced into contact with one another by the closing operation of the filter press.
