A discharge port 19 is opened in the middle of the bottom end of the box body 1, and a supporting mechanism is arranged inside the box body 1 near the bottom of the filter press frame 2;

[0026] When the hydraulic rod 15 drives the pressing plate 14 to enter the filter press tank 3, the graphite powder containing liquid is transported into the filter press tank 3 through the feeding hose 17, and then the hydraulic rod 15 drives the pressing plate 14 to continue to press down to filter the graphite powder. The liquid flows out from the U-shaped tube 6 after passing through the filter plate 4. After the filtration is completed, the pressing plate 14 moves up and drives the filter press frame 2 to rotate 180° through the flipping mechanism, so that the filter press tanks 3 on both sides are exchanged, and then continue to filter through the upward filter press tank 3. When the opening of the filter press tank 3 faces downward, the graphite powder after filtration falls due to gravity and is discharged from the discharge port 19. Through the filter press device, by controlling the flipping of the filter press frame 2 and the two filter press tanks 3, continuous filtration can be performed, which effectively improves the working efficiency of the filter press device.

[0027] See also Figures 1 to 4 The connecting position between the U-shaped tube 6 and the filter press support 2 is located between the filter plate 4 and the partition plate 5.

Then, the screw rod 25 is provided with two sections of opposite external threads, and the screw rod 25 is threadedly connected to the clamping frames 20 on both sides through the two sections of opposite external threads. When the filter press frame 2 is flipped, the second motor 26 drives the screw rod 25 to rotate, so that the screw rod 25 drives the clamping frames 20 on both sides to move away from each other, so that the clamping frames 20 on both sides drive the insertion rod 22 to move out of the slot 21, so that the filter press frame 2 can be flipped. After the flipping is completed, the screw rod 25 rotates in the opposite direction, so that the clamping frame 20 drives the insertion rod 22 to insert into the slot 21. Through the supporting mechanism, the filter press frame 2 can be supported when the filter press frame 2 is filtering, so as to avoid damage to the rotating structure of the U-shaped tube 6 and the rotating shaft 7 caused by the force on the filter press frame 2.

[0029] Working principle: This is a filter press device for preparing crude graphite powder. When the hydraulic rod 15 drives the pressing plate 14 to enter the filter press tank 3, the graphite powder containing liquid is transported into the filter press tank 3 through the feeding hose 17. Then the hydraulic rod 15 drives the pressing plate 14 to continue to press down to filter the graphite powder. The liquid flows out from the U-shaped tube 6 after passing through the filter plate 4. After the filter press is completed, the pressing plate 14 moves up and drives the filter press frame 2 to rotate 180° through the flipping mechanism, so that the filter press tanks 3 on both sides are exchanged, and then the filter press is continued through the upward filter press tank 3. When the opening of the filter press tank 3 faces downward, the graphite powder after the filter press falls due to gravity and is discharged from the discharge port 19. Through the filter press device, by controlling the flipping of the filter press frame 2 and the two filter press tanks 3, the filter press can be continuously performed, which effectively improves the working efficiency of the filter press device;

[0030] When it is necessary to control the filter press frame 2 to flip, the first motor 10 drives the worm 12 to rotate, and the worm 12 drives the worm wheel 11 to rotate through meshing, and then drives the rotating shaft 7 to rotate through the worm wheel 11, so that the rotating shaft 7 drives the filter press frame 2 to flip, and the one-way transmission structure formed by the worm wheel 11 and the worm 12 can prevent the filter press frame 2 from automatically flipping due to force, and when the filter press frame 2 flips, the second motor 26 drives the screw rod 25 to rotate, so that the screw rod 25 drives the clamping frames 20 on both sides to move away from each other, so that the clamping frames 20 on both sides drive the insertion rod 22 to move out of the slot 21, so that the filter press frame 2 can flip, after the flipping is completed, the screw rod 25 rotates in the opposite direction, so that the clamping frames 20 drive the insertion rod 22 to insert into the slot 21, and through the supporting mechanism, the filter press frame 2 can be supported when the filter press frame 2 is filtering, so as to prevent the filter press frame 2 from being subjected to force and causing the rotating structure of the U-shaped tube 6 and the rotating shaft 7 to be damaged.
