Dual-purpose limiting device for cake discharge and filtering cloth washing by grouping and pulling filtering plates of efficient filter press

Abstract

The invention discloses a dual-purpose limiting device for cake discharge and filtering cloth washing by grouping and pulling filtering plates of an efficient filter press. The dual-purpose limiting device is characterized by mainly comprising components such as a cake discharge limiting device, a filtering cloth limiting device and an L-shaped limiting adjusting plate. On the basis of a conventional cake discharge limiting device, a filtering cloth cleaning limiting device is additionally arranged and is in communication with a PLC (programmable logic controller) cabinet; the two limiting devices are fixed on the L-shaped limiting adjusting plate (the positions are adjustable), the cake discharge limiting device is on a side close to a push plate, the filtering cloth cleaning limiting device is on a side close to a base (far away from the push plate), the two limiting devices are kept in a distance of about 150mm from each other, and the limiting adjusting plate is mounted on a transverse beam of a filter press behind the push plate; and the two limiting devices are interlocked to respectively control final stopping positions of filtering plates in cake discharge and filtering cloth cleaning, each group of the filtering plates are connected through chains of equal lengths, groups of the filtering plates are connected through longer chains, lengths of the chains for connectingthe groups and positions of the two limiting devices are adjusted, and one-key automatic completion of single complete operation circulation of a filter press of which filtering plates are grouped andpulled can be achieved.

Description

technical field [0001] The invention belongs to the technical field of automatic filter presses, and relates to a dual-purpose limiting device for filter plate grouping, cake unloading and cloth washing. Background technique [0002] The filter press is a general intermittently operated multi-chamber pressurized filtration equipment. The high-efficiency filter press has a filter plate grouping automatic pulling mechanism (commonly known as: pull plate trolley) and an automatic filter cloth cleaning mechanism (commonly known as: water washing) trolley), and the automatic filter press with short cycle time is intelligently controlled by PLC+ touch display screen, and a single operation cycle (from pressing the filter plate, feeding, pressing, washing, drying, back blowing, pulling the plate to unload the cake, Irregular cleaning of the filter cloth) One-key automatic cake unloading, two-key complete cloth washing, suitable for solid-liquid separation of various suspensions; mo...
