Embodiment 1

[0017] A dual-purpose limiting device for cake unloading and cloth washing by grouping the filter plates of a high-efficiency filter press. It is composed of components such as positioner 3, and has a simple structure; its outstanding substantive feature is that it innovates the operating procedure, and on the basis of the original cake unloading limiter, a cloth washing limiter 2 is added, and it is connected with the PLC program control cabinet 12 ; Both limiters are fixed on the L-shaped limit adjustment plate 1 (position adjustable), the cake unloading limiter 3 is close to the side of the push plate 9, and the cloth washing limiter 2 is close to the side of the machine base 8 (from the The push plate 9 is far away), keep a certain distance (100mm to 200mm) from each other, and the limit adjustment plate is installed on the filter press beam 14 behind the push plate 9; the two limiters are interlocked to control the cake unloading and cloth washing respectively Pull the fi...

Embodiment 2

[0021] The filter plates are grouped to pull apart the dual-purpose limit device for cake unloading and cloth washing and the corresponding operating procedure for cake unloading of the high-efficiency filter press: the PLC program control system of the high-efficiency filter press defaults to the cake unloading limiter 3 (NBN25-30GM65-E2 The sensor) is in the "normally open" state. When the filter press completes the filtration and only needs to unload the cake (most of the cycle operations do not need to clean the filter cloth), the pull plate trolley 10 automatically groups and pulls the filter plate 6 to realize the gravity unloading of the cake; The process of pulling plate unloading cake is: the pulling plate trolley 10 pulls the head plate 7 of the first group of filter plates (the first filter plate of each group, the first set of head plate is the push plate) to drive the whole set of filter plates 6 to move forward, when The cake unloading limiter 3 senses the head pl...

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...
