Background
The filter press is a main filtering device in the solid-liquid separation industry and is widely used in municipal environmental protection, food and beverage, chemical pharmacy, petrochemical industry, printing and dyeing industry, papermaking industry and other related industries. When the filter press works, each filter plate is pressed between the thrust plate and the pressing plate through the oil cylinder, so that a filter chamber is formed between each filter plate, solid particles are trapped in the filter chamber by filter cloth to form a filter cake in the flow process of the filter chamber after the material is pumped into the filter chamber, and filtrate is discharged out of the filter chamber through the filter cloth, so that solid-liquid separation of the material is realized.
After the filtration is completed, the compacting plates are retreated, the filter plates are sequentially pulled by the plate pulling device to discharge cakes, and the filter cloth is vibrated by the vibration cake discharging device to assist cake discharging in the process of pulling the filter plates, so that the filter cakes adhered on the filter cloth fall fully. For example, the patent with publication number CN212818345U provides a filter cloth supporting mechanism and cake unloading mechanism, which can shake the supporting rod suspending the filter cloth by a shaking cylinder, so that the filter cloth shakes, and the filter cake adhered on the filter cloth shakes off. The vibrating cylinder is arranged on the portal frame, the portal frame moves along the guide rail on the main beam, the bottom of the portal frame is fixedly connected with the plate pulling device, and the portal frame is driven to synchronously move through the plate pulling device.
When the filtering efficiency of the filter cloth is reduced, the filter cloth can be washed, the cloth washing device is generally arranged on the filter plate in a crossing manner, and the cloth washing device is driven by the driving mechanism to move along the guide rail on the main beam so as to clean the filter cloth.

When the rod of the cylinder 730 is extended, the pressure plate 720 is pushed toward the thrust plate 710, and the filter plates 500 located between the pressure plate 720 and the thrust plate 710 are pressed against each other to form a filter chamber. After the filtration is completed, the cylinder 730 is retracted to drive the hold-down plate 720 away from the thrust plate 710.

After the cylinder 730 pulls the hold-down plate 720 to the cylinder seat 731, the plate puller 200 can reciprocate to sequentially pull each filter plate 500.
After the filter plates 500 are pulled apart, a large portion of the filter cake can naturally fall out from between the filter plates 500, but a small portion still adheres to the filter cloth 510. In order to sufficiently clean the filter cake adhered to the filter cloth 510, a rapping cake discharging operation is required. The rapping cake discharging mode is a common mode, and the rapping cake discharging operation is usually required after the pulling plate is finished. The cloth washing mode is started according to the cleaning degree of the surface of the filter cloth, and the two modes are switched through the PLC control cabinet.
The working processes of the vibration cake discharging working mode and the cloth washing working mode are specifically as follows:
(1) The working mode of shaking and cake discharging is as follows:

After the first filter plate is pulled apart, most of the filter cake between the first filter plate and the next filter plate falls under the action of gravity, but a part of the filter cake still adheres to the filter cloth 510. In order to sufficiently separate the filter cake adhered to the filter cloth 510, the rapping element 120 of the rapping device 100 starts to operate to rapp the filter cloth so that the filter cake adhered to the filter cloth 510 is sufficiently separated in the process that the plate pulling device 200 moves with the filter plate in the direction of the pressure plate 720. Then repeating the above actions, pulling the next filter plate open and vibrating until the cake unloading of all filter plates is completed.
The plate puller 200 and the cloth shake-out apparatus are both positioned on the first rail 410, and in order to bring the plate puller 200 sufficiently close and grip the filter plate to be pulled apart, the plate puller 200 is typically positioned between the end of the thrust plate 710 and the shake-out apparatus 100.

Then, the plate puller 200 works independently, the pulling plate is moved towards the thrust plate 710, and the cloth washing device 600 moves towards the pressing plate 720 to be close to the filter plate to be washed, so that the filter cloth on the filter plate can be washed by the cloth washing device 600. The above-described actions are repeated until all filter plate washings are completed. The cloth washing element 620 of the cloth washing apparatus 600 can be lifted up and down to wash the filter cloth comprehensively.
