NGWAFOR & PARTNERS SARL, The House of Gideon, Golf/Bastos Quarter, Opposite The American Embassy, Entrance-Saint John Paul II Boulevard, B.P. 8211, YAOUNDE (CM). (57) The present disclosure concerns a filter plate frame assembly (1) and a horizontal filter press, in which accidental overpressurization of the filter diaphragm (5) is prevented. A filter plate frame assembly (1) having a separate subframe (4) is provided with a limited vertical travel with respect to the filter frame (2) and the filter plate (3), such that the subframe (4) is allowed to drop away from the filter plate (2) when the filter chamber is opened. This enables a diaphragm (5) to be attached to the subframe (4) such that an escape route is formed for a pressurized medium accidentally introduced between the filter plate (3) and the diaphragm (5). Moreover, the limited travel of the subframe (4) allows the subframe (4) to be pressed towards the filter plate (3) when the filter chamber is closed, thereby allowing normal operation of the diaphragm (5) for squeezing a filter cake.
