FILTER PRESS Russian patent published in 2023 - IPC B01D25/12 

FIELD: separation of solid and liquid substances.

SUBSTANCE: chamber filter press contains a main beam, a thrust plate, filter plates, filter plate handles, devices for extending plates, a pushing plate, a push frame, a chain and sprockets, the thrust plate is located on the main beam, the sprockets are located at both ends of the main beam, the chain mounted on sprockets, the handles of the filter plates are respectively located on both sides of the filter plates, the pushing plates are located on the chain at intervals, the push frame is located on the push plate, and a hook is snapped on one filter plate handle to pull out the plate of each pushing plate. In the chamber filter press according to this application, the plate pusher is circularly extended by a chain, the pusher’s hook extends the handles of the filter plate to move the filter plate, and on the right side, the hook pushes the previous filter plate, and the current filter plate and the previous filter plate are interlocked with each other, and the force applied when said hook pushes the filter plate is smooth, which prevents the filter plate from rebounding, the filter plates are combined with each other, pushing and pulling out are performed simultaneously with decreasing gap between the filter plates, so that with the same length, the number of filter plates is increased and the filtration area is larger, which improves the filter press's processing ability.

EFFECT: reduced working force of the plate pusher and increased filter press productivity.
