Description

Technical Field

[0001] The invention relates to the technical field of graphene slurry filtering and purification devices, in particular to a graphene slurry filtering and purification device with a filter screen cleaning component. Background Art

[0002] Graphene slurry filtration and purification device is usually a device specially designed for processing graphene slurry, the purpose of which is to remove solvents, impurities and large-sized particles from the slurry to improve the purity and concentration of graphene.

[0003] For example, the "graphene slurry filtering and purification mechanism with a filter screen cleaning component" with publication number CN220899693U includes a purification box, a hole is inserted in the front of the purification box, a driving motor is fixedly installed on one side of the purification box, a transmission rod is splined to the output end of the driving motor, a threaded rod is fixedly installed on one end of the transmission rod, a brush plate is threadedly connected to the surface of the threaded rod, and a driving wheel is fixedly installed on one end of the threaded rod. The graphene slurry filtering and purification mechanism with a filter screen cleaning component is arranged by the cooperation of the driving motor, the transmission rod, the threaded rod and the brush plate. When in use, the driving motor drives the transmission rod and the threaded rod to rotate, thereby driving the brush plate to brush the filter screen, and then manually pulls out the hole for cleaning, thereby facilitating the cleaning of the filter screen surface and effectively preventing the filter hole from being blocked.

[0004] However, in the prior art, since the existing graphene filtering and purification device only has the function of cleaning, but does not have the function of discharging larger particles in the larger graphene slurry, this will cause the brush plate to repeatedly move the larger particles in the graphene slurry on the surface when cleaning, and the particles cannot be discharged, and the clogging of the filter holes cannot be prevented.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1.

At the same time, the rotating rod A and the rotating rod B will also roll in the limit groove B on the limit block A and the limit block B, so that the brush plate slides on the surface of the guide plate B and the filter plate, and the particles on the surface of the filter plate are discharged from the screening chamber through the discharge port, thereby preventing the particles from adhering to the filter plate and causing the filter plate to be blocked and affecting the screening effect of the graphene slurry, and also avoiding the need to clean the filter plate separately.

[0018] 2. In the present invention, the cover plate C is driven to rotate by the torsion spring A. When the cover plate C rotates, it will drive the limit plate A to rotate. When the limit plate A rotates, it will drive the connecting rod to rotate. At the same time, the connecting rod will also rotate on the surface of the slider. At this time, the connecting rod will drive the slider to slide upward in the limit groove C, and the slider will drive the guide rod to move upward. After the guide rod is away from the guide plate D, the guide plate D will rotate due to the torsion force of the torsion spring B until the bottom of the feed hopper is closed. At this time, the graphene slurry can be introduced into the feed hopper. After the slurry is introduced, the cover plate C is Rotate, and after the insert block A is inserted into the feed hopper, insert the insert strip into the insert block A, so that the cover plate C is closed, and when the cover plate C is rotated again, it will drive the slider to slide downward in the limit groove C through the limit plate A and the connecting rod, so that the guide rod moves downward until the guide plate D is pushed open, so that the slurry in the feed hopper can be introduced into the screening chamber through the guide plates C and D. The design of the guide plate D and the cover plate C prevents dust or impurities in the air from entering the screening chamber when pouring the slurry, which may cause the graphene slurry to be contaminated.

[0019] 3. In the present invention, the lever is moved to slide in the limit slot D, and the lever drives the insert block B to slide in the guide plate B, thereby driving the fixed block to slide in the guide plate B. After the fixed block slides out of the fixed slot, the filter plate can be taken out from the placement slot. At this time, the filter plate drives the limit plate to slide in the slot. After the filter plate is pulled out, a new filter plate is inserted into the slot through the limit plate B. After the filter plate slides into the placement slot, the insert block B is driven to slide in the guide plate B by the spring, thereby inserting the fixed block into the fixed slot. The detachable design of the filter plate facilitates the efficient replacement of the filter plate, and also avoids the need to use disassembly tools to disassemble the filter plate.

[0037] The use method and working principle of the device: When the graphene slurry is screened, the electric push rod 9 is first opened, and the electric push rod 9 drives the cover plate B10 to slide in the guide plate A8 until the discharge port 7 is closed, and the motor 11 can be opened. At this time, the motor 11 drives the gear A12 to rotate, and the gear A12 drives the transmission shaft 13 to rotate when rotating, and the transmission shaft 13 drives the reciprocating screw rod 14 to rotate, and the reciprocating screw rod 14 drives the connecting block 17 to move up and down when rotating, and the connecting block 17 drives the limit rod A16 to slide in the limit groove A15, and the connecting block 17 moves up and down when rotating.

At the same time, the other ends of the rotating rods A20 and B21 will also rotate on the surfaces of the limiting blocks A22 and B23 respectively, so that the limiting blocks A22 and B23 will roll in the limiting groove B24, and the limiting blocks A22 and B23 will drive the brush plate 27 to slide on the surface of the guide plate B25, so as to scrape off the particles on the surface of the brush plate 27, and then drive the cover plate B10 to move upward by driving the push rod, and the particles can be passed through the discharge port 7B after the discharge port 7B is opened. The brush plate 27 cooperates with the guide plate B25 to discharge the particles on the filter plate 26 out of the screening chamber 201 through the guide plate A8, thereby avoiding the adhesion of particles on the filter plate 26 and affecting its screening effect and efficiency; the screened graphene slurry enters the purification chamber 202, and the gear A12 rotates through the toothed chain 31 electric gear B28, and the gear B28 rotates when it rotates, and the rotating shaft 29 drives the stirring rod 30 to stir the graphene slurry in the purification chamber 202. Stirring, at this time, slide the cover plate A6, and after the feed port 5 is opened, the volume of graphene slurry for purification can be poured into the purification chamber 202 to make it fully dissolved, and finally the graphene slurry can be discharged from the purification chamber 202 through the discharge valve. The design of the gear A12, the gear B28 and the toothed chain 31 plays the role of cleaning the surface of the filter plate 26 through the brush plate 27, and also plays the role of driving the stirring rod 30 to stir the graphene slurry in the purification chamber 202, thereby improving the screening efficiency of the screened graphene slurry and also improving the purification efficiency of the graphene slurry;

[0038] When the graphene slurry needs to be poured into the screening chamber 201, it is only necessary to move the insert 413. After the insert 413 slides out of the insert block A404, the cover plate C403 will rotate due to the torsion force of the torsion spring A402. When the cover plate C403 rotates, it will drive the limit plate A405 to rotate. The limit plate A405 will drive the connecting rod 406 to rotate. At the same time, the other end of the connecting rod 406 will also rotate on the surface of the slider 407, so that The slider 407 slides upward in the limit groove C409, and the slider 407 drives the guide rod 408 away from the guide plate D412. At this time, the guide plate D412 is rotated by the torsion force of the torsion spring B411 until the bottom of the feed hopper 4 is closed. At this time, the graphene slurry can be poured into the feed hopper 4. After the slurry is poured, the cover plate C403 can be rotated, and the cover plate C403 drives the plug block A404 to rotate. After the cover plate C403 is rotated to the feed hopper 4, the insert 413 can be slid, and after the insert 413 is inserted into the insert block A404, the cover plate C403 can be fixed and the top of the feed hopper 4 can be closed. While the cover plate C403 is rotating, the slider 407 can be driven to slide downward in the limit groove C409 through the limit plate A405 and the connecting rod 406, and the slider 407 can drive the guide rod 408 to move downward, and the guide rod 408 can make The guide plate D412 rotates, and when the guide plate D412 is away from the feed hopper 4, the graphene slurry in the feed hopper 4 can be poured into the screening chamber 201 through the guide plate C301 and the guide plate D412. The design of the cover plate C403 and the guide plate D412 prevents dust or impurities in the air from entering the screening chamber 201 when the graphene slurry is poured into the screening chamber 201, thereby causing the graphene slurry to be contaminated;

[0039] When the filter plate 26 needs to be replaced, the lever 510 only needs to be moved, so that the lever 510 slides in the limit slot D505. When the lever 510 slides, it also drives the insert block B508 to slide in the guide plate B25, so that the sliding of the insert block B508 drives the fixed block 509 to slide in the guide plate B25. After the fixed block 509 slides out of the fixed slot 504, the filter plate 26 can be taken out of the placement slot 501. At this time, the filter plate 26 drives the limit plate to slide in the slot 502. After the filter plate 26 is taken out, a new filter plate 26 is inserted through the limit plate. The positioning plate B503 is inserted into the slot 502. After the filter plate 26 slides into the placement slot 501, the lever 510 is released, and the insertion block B508 is slid in the guide plate B25 by the elastic force of the spring 507, thereby driving the fixing block 509 to be inserted into the fixing slot 504. After the fixing block 509 is inserted into the fixing slot 504, the filter plate 26 can be replaced. The detachable design of the filter plate 26 facilitates the efficient replacement of the filter plate 26, and also avoids the need to use disassembly tools to disassemble the filter plate 26.
