[0024] The pressure sensing support seat group 652 includes a first support plate 6521 and a second support plate 6522, and a plurality of support slides 6523 are arranged on the bottom side of the first support plate 6521, and the lower end of each support slide 6523 is movable through the second support plate 6522, and a compression spring 6524 is sleeved on the rod body of each support slide 6523, and a pressure sensor 6525 is arranged in the middle between the first support plate 6521 and the second support plate 6522.

The knocking plate roller 662 is provided with a plurality of protrusions 665 at the upper and lower ends of the cylinder body. The knocking plate roller 662 and each protrusion 665 are an integrated structure and are made of rubber. The pulley group 663 is composed of two pulleys and a transmission belt.

[0026] Working principle: During operation, first, the unloading plate group 5 is flipped up to the left, and the first motor 63 is rotated to drive the gear and rack 622 to make the sliding beam body 621 move horizontally to the left on the sliding seat 61. First, the knocking plate assembly 66 pushes the unloading plate group 5 to flip up to the left at a certain angle. When it reaches a specific angle, it will automatically connect to the pressing assembly 65 to continue to push and push so that the unloading plate group 5 can be completely flipped up to the left and fit with the unloading port 22, and the pressing assembly 65 presses the first oblique section 53 at an inclined angle. At this time, the peripheral edge of the sealing pressure plate 51 will be softly pressed and sealed with the sealing gasket 23, and the synchronous pressure sensor 6525 will sense the thrust, so that the sealing force between the sealing pressure plate 51 and the sealing gasket 23 is just right. It should be noted that the pushing force of the pressing component 65 after the fitting will be greater than the force with which the filter cake presses the discharge plate group 5 downward during filtration by the filter press telescopic end 4. This ensures that the discharge plate group 5 will not be squeezed downward during filtration, causing a poor seal. The sensing pushing force of the pressure sensor 6525 on the pressing component 65 is the fitting strength of the subsequent sealing pressure plate 51. If sealing leakage occurs after long-term use, the sealing leakage problem can be solved by increasing the pushing force of the pressing component 65, so that the auxiliary unloading structure 6 can push the sealing plate with just the right force to slide the discharge plate group 5 to the left, and then feed the filter chamber 21, while the filter press telescopic end 4 and the filter plate 3 cooperate to squeeze and filter to form a filter cake.

[0027] When the unloading plate group 5 is to be turned down to the left to unload, the auxiliary unloading structure 6 is horizontally moved to the right, and the first inclined section 53 is tilted to the upper right, so that the pushing force of the pressing component 65 on the unloading plate group 5 is cancelled, so that the unloading plate group 5 will automatically turn down under the pressure of its own gravity and the weight of the filter cake, and the pressing roller 654 and the first inclined section 53 are always in a state of abutment. When the unloading plate group 5 reaches a specific angle, the abutment of the pressing roller 654 and the first inclined section 53 will be connected to the first inclined section 53 by the knocking plate roller 662. Thereby, the knocking plate assembly 66 and the discharge plate group 5 are abutted against each other to open the plates at a large angle for auxiliary unloading, so that the filter cakes are automatically discharged downward. At this time, some filter materials will stick to the anti-stick coating 55, and the second motor 664 is rotated, through the pulley group 663, so that the knocking plate roller 662 and the various protrusions 665 are rotated, and softly abut against each other to knock on the right side of the discharge plate group 5, so that the discharge plate group 5 can be swung left and right with a small amplitude to allow the filter materials stuck on the anti-stick coating 55 to vibrate and detach, thereby realizing the auxiliary unloading structure 6 knocking on the discharge plate group 5 to assist in unloading.
