[0029] For example, such as Figure 1 As shown, the control unit 201 includes a dual-axis motor 201a fixedly connected to the right side of the base frame 101. Rotating rods 201b are fixedly provided on the front of the two output rods of the dual-axis motor 201a, and bevel gears 201c are fixedly sleeved on the surface of the two rotating rods 201b.

[0030] For example, such as Figure 2As shown, the unloading part 202 includes two connecting rods 202a rotatably connected to the inner walls of the front and rear ends of the base frame 101. The surface of the connecting rod 202a is fixedly connected to the inner wall of another bevel gear 201c. The two bevel gears 201c are connected by inclined meshing. The surfaces of the two connecting rods 202a are each fixedly fitted with unloading plates 202b. The side of the unloading plate 202b is in sealed contact with the side of the base frame 101.

[0031] For example, such as Figure 2 As shown, the purification unit 301 includes a hydraulic cylinder 301a fixedly connected to the inner wall of the support frame 1031. A push plate 301b is fixedly provided on the left end face of the output rod of the hydraulic cylinder 301a. Multiple filter plates 301c are slidably connected to the surfaces of the two limit rods 1032 and the inner wall of the base frame 101. Two trigger rods 301d are fixedly provided on the front and rear end faces of the filter plates 301c respectively.

[0032] For example, such as Figure 2 and Figure 3 As shown, the control unit 302 includes two fixed plates 302a fixedly connected to the front of the fixed frame 102. A motor 302b is fixedly installed on the right side of the right fixed plate 302a. The left end of the output rod of the motor 302b extends through the right side of the fixed plate 302a into the interior of the fixed plate 302a and is fixedly connected to a threaded rod 302c. The surfaces of the two threaded rods 302c are rotatably connected to the inner wall of the fixed plate 302a. Gears 302g are fixedly sleeved on the surfaces of the two threaded rods 302c. The two gears 302g are connected by a toothed belt drive.

[0033] For example, such as Figure 3 and Figure 4 As shown, a movable block 302d is threadedly sleeved on the surface of the threaded rod 302c. The side of the movable block 302d is slidably connected to the surface of the fixed frame 102. A rotating rod 302e is rotatably connected to the inner wall of the movable block 302d. A clamping plate 302f is fixedly sleeved on the surface of the rotating rod 302e.

[0034] Working principle: During use, the material to be purified is placed inside the two filter plates 301c and fixed in place. An external water pipe is connected to the surface of the input pipe 1034, allowing cleaning water to flow into it. The hydraulic cylinder 301a is activated, causing the push plate 301b to move to the left. Combined with the action of the limit rod 1032, this causes the filter plates 301c to squeeze against each other. The squeezed liquid falls onto the discharge plate 202b and is collected by flowing to the left at a slight tilt angle. The dual-shaft motor 201a is activated, causing the two rotating rods 201b to rotate. Through the meshing transmission of the bevel gear 201c, the two connecting rods... 202a drives the two feeding plates 202b to flip and open, and after the hydraulic cylinder 301a is stored, the motor 302b is started, which makes the threaded rod 302c rotate. It moves left and right through the two moving blocks 302d until it reaches the appropriate position. Then, the rotating rod 302e is grasped to flip the clamping plate 302f. The motor 302b is started again, which makes the clamping plate 302f drive the filter plate 301c to move. The filter cake can be fed down quickly. The stubborn filter cake can be cleaned manually. In addition, the cleaning water is used to clean the filter plate 301c through the input pipe 1034. The control valve 1036 can be opened to clean the circulation pipe 1035.
