The inside of the clamping plate weldment 17 is fixedly connected to a dual-axis motor 20, and the two output ends of the dual-axis motor 20 are fixedly connected to a rotating shaft 19. The surfaces of the two rotating shafts 19 penetrate the surface of the clamping plate weldment 17 and are rotatably connected to the inside of the clamping plate weldment 17. One end of the two rotating shafts 19 located outside the clamping plate weldment 17 is fixedly connected to a gear 18. The bottom of the two main beams 3 is fixedly connected to a rack 5. The rack 5 and the main beam 3 can also be assembled and used by bolts. The two gears 18 are respectively It is meshed with the surfaces of the two racks 5, so that the two gears 18 can be driven to rotate by starting the dual-axis motor 20, and the meshing of the gears 18 and the racks 5 can be used to drive the clamping plate weldment 17 and the filter plate 9 to approach the thrust plate 33, thereby applying pressure to the object so that the liquid can seep out, and the meshing of the gears 18 and the racks 5 can drive the movement of the filter plate 9 to complete the pressing process, so that the main beam 3 only bears the gravity of the filter plate, which simplifies the structure of the main beam 3 and greatly reduces the cost of the main beam 3.

[0031] A cylinder seat assembly 11 is provided on one side of the thrust plate 33, and the cylinder seat assembly 11 includes a cylinder seat 24, which is installed on the thrust plate 33. Four second cylinders 23 are fixedly connected to the surface of the cylinder seat 24, and the output ends of the four second cylinders 23 all penetrate the surface of the thrust plate 33 and are slidably connected to the inside of the thrust plate 33. A beam 8 is provided at the output end of the second cylinder 23, and a connecting nut 10 is provided between the output end of the second cylinder 23 and the beam 8. The output end of the second cylinder 23 and the surface of the beam 8 are threadedly connected to the inner wall of the connecting nut 10, so as to connect the output end of the second cylinder 23 with the beam 8.

[0032] The surface fixing tube of the second bracket 7 is connected to two fixing frames 16, and the inner walls of the two fixing frames 16 are rotatably connected to rollers 15. The surfaces of the rollers 15 are in contact with the surface of the beam 8 to support the beam 8, while reducing the friction when the beam 8 slides, reducing the wear between the beam 8 and the fixing frames 16, and improving the service life of the device.

[0035] A slot 32 is formed on the surface of the output end of the second oil cylinder 23 . When the second oil cylinder 23 is fully extended, the slot 32 can correspond to the upper locking block 27 and the lower locking block 28 .

[0036] Among them, the dual-axis motor 20, the first oil cylinder 21, the second oil cylinder 23 and the double-head oil cylinder 26 are also matched with a power supply, wires, a controller and a microcomputer, etc., which are not the main structures and will not be detailed.

[0037] During operation, the user turns on the switch, and energizes and starts the dual-axis motor 20 through the microcomputer and the controller, thereby driving the gear 18 to rotate through the rotating shaft 19, and driving the clamping plate assembly 6 and the filter plate 9 to approach the clamping plate weldment 17 through meshing with the rack 5, thereby applying pressure to the object, causing the liquid to percolate out and achieve solid-liquid separation, and then the second oil cylinder 23 can be started to drive the beam 8 to move toward the clamping plate assembly 6, so that the plug block 12 is inserted into the connecting sleeve 13, and the two pin holes 14 overlap each other, and then the first oil cylinder 21 is started to drive the pin shaft 22 to be inserted into the plug block 12 and the connecting sleeve 13 The pin hole 14 connects the plug block 12 and the connecting sleeve 13 together, thereby connecting the beam 8 and the clamping plate assembly 6 together, and then the guide column 25 is started to drive the upper locking block 27 to approach the second cylinder 23, so that the connecting rod 29 gradually tends to be horizontal from an inclined state, thereby pulling the lower locking block 28 to also approach the second cylinder 23, and then the upper locking block 27 and the lower locking block 28 are both inserted into the card slot 32, thereby locking the output end of the second cylinder 23, making the second cylinder 23 unable to be retracted, so that the device maintains pressure, provides sufficient time for liquid dialysis, and improves the solid-liquid separation effect.
