A filter plate frame assembly and a horizontal filter press, in which accidental over pressurization of the filter diaphragm is prevented. A filter plate frame assembly having a separate subframe is provided with a limited vertical travel with respect to the filter frame and the filter plate, such that the subframe is allowed to drop away from the filter plate when the filter chamber is opened. This enables a diaphragm to be attached to the subframe such that an escape route is formed for a pressurized medium accidentally introduced between the filter plate and the diaphragm. Moreover, the limited travel of the subframe allows the subframe to be pressed towards the filter plate when the filter chamber is closed, thereby allowing normal operation of the diaphragm for squeezing a filter cake.

A filter diaphragm for a horizontal plate and frame-type filter, such as a tower press, including a sheet like body and at least on a filter plate-facing side thereof, a continuous seal bead. The seal bead includes an inner seal lip on a lateral inside of the seal bead and an outer seal lip surrounding the inner seal lip on a lateral outside of the seal bead. The outer seal lip is elevated from the inner seal lip in a vertical direction perpendicular to a general plane defined by the diaphragm.

A filter plate frame assembly with a filter plate frame and a subframe housed within the frame, such that the subframe can be removed from the frame without removing the frame from the filter press. In this way, consumable components can be provided in connection with the subframe, which can be easily removed from the filter press. This, in turn, makes replacement of worn components faster, as the whole frame does not need to be removed from the filter press. An associated horizontal filter press and a method of replacing worn components of such a filter press is also provided.

A filter press device includes a supporting frame and elongated side rails disposed parallel and horizontally on the supporting frame. A following head assembly is disposed on an end portion of the supporting frame, and a following head assembly is movably disposed on another end portion of the supporting frame. The elongated side rails support a combination of filter plates of varying sizes through one or more adapters. An adapter plate interposes between adjacent filter plates of different sizes, providing fluidic communication between the different sized filter plates.

A horizontal filter press (100) is provided with a track (105) and a plurality of filter plate assemblies (101) supported by side bars (104). A washer carriage (2), which is movably supported on the track (105), includes a washer unit (1) for washing the filter plate assemblies (101). The washer unit (1) may include a wash water manifold (11) having a first outlet (13) for feeding wash water to a first spindle (19) and a second outlet (14) for feeding wash water to a second spindle (19). Each of the spindles (19) may include a reel (20) for spooling a flexible hose (23) thereon, and they are each configured to be rotated with respect to the washer carriage (2). A first end of a spray bar (25) fluidly communicates with a first flexible hose (23) supported by a reel (20) on the first spindle (19).
