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).

A filter press includes a frame, a hydraulic system for compressing and releasing filter plates, the filter plates, a filter chamber, a feed pump, a high-pressure clean water pump, a control system, a rotating plate, a cake removal knife, a squeeze disc, a squeeze disc sleeve, a drive shaft, a brake, a left pull rod, a right pull rod, a pull rod disc, a connector and clutches. The filter cake in the entire filter press can be removed without opening the filter plates in sequence. The filter cake washing is carried out in an enclosed room in a normal direction and a reverse direction, which can not only maintain the dryness and cleanness of the working environment, but also can effectively collect, process treat and recycle the washing water, thus achieving the zero discharge of waste water to meet the environmental requirements at a low cost.

A method of cleaning a filter cloth of a filter press including a first cleaning nozzle and a second cleaning nozzle which jet cleaning liquid from positions upper right and left of the filter cloth toward respective diagonal corners of the filter cloth, the method including: jetting the cleaning liquid from only the first cleaning nozzle; and jetting the cleaning liquid from only the second cleaning nozzle.

A filter (20) configured to separate the solid components and the liquid components from a slurry. The filter (20) includes a plurality of filter plate assemblies (46) that cooperate to define a plurality of filter chambers (70), each defining a perimeter (96) having an open section (98) when the filter plates (68) are in a closed position relative to one another. Each filter plate assembly (46) includes a closure (104) configured to close the open section (98). Preferably, the closures (104) are movable to an open position to permit a particulate cake to be removed from the filter chambers (70) without separating the filter plates (68).
