Description

Technical Field

[0001] This utility model relates to the field of dispersion equipment technology, specifically a graphene conductive slurry uniform disperser. Background Technology

[0002] Graphene conductive paste needs to be uniformly dispersed to ensure that its excellent conductivity and other physical properties can be fully utilized. Graphene is a two-dimensional honeycomb carbon material with extremely high conductivity and many other excellent properties. However, the large specific surface area of ​​graphene often makes it prone to agglomeration. This agglomeration not only reduces the adsorption capacity of graphene, but also affects the performance of graphene's excellent properties. In graphene conductive paste, if graphene cannot be uniformly dispersed, the agglomerates will lead to a decrease in the conductivity of the paste, affecting the application effect of the paste in electronic devices.

[0003] Currently, when dispersing graphene conductive slurry, ordinary agitators cannot ensure uniform dispersion, and the slurry tends to stick to the walls during the dispersion process, resulting in uneven dispersion and affecting the performance of the graphene conductive slurry. To address these issues, the inventors have proposed a graphene conductive slurry uniform disperser to solve the problems. Utility Model Content

[0004] To address the issues of uneven dispersion and wall adhesion in current graphene conductive slurry dispersion processes, the present invention aims to provide a uniform disperser for graphene conductive slurry.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a graphene conductive slurry uniform disperser, comprising a base, a lifting platform being movably mounted on the top surface of the base, a storage cylinder being fixedly connected to the top surface of the lifting platform, a vertical plate being fixedly connected to the side wall of the base, an ultrasonic generator and an ultrasonic transducer being mounted on one side of the vertical plate, the ultrasonic generator and the ultrasonic transducer corresponding to and cooperating with each other, a toothed ring being mounted on one side of the ultrasonic generator, the ultrasonic transducer being located inside the ring opening of the toothed ring, a convex ring being fixedly connected to the bottom surface of the toothed ring, a slide rail being fixedly connected to the bottom surface of the convex ring, a sliding sleeve being slidably connected to the side wall of the slide rail, a scraper being fixedly connected to the bottom surface of the sliding sleeve, a motor being mounted on one side of the toothed ring, a gear being fixedly connected to the output shaft end of the motor, the gear corresponding to and meshing with the toothed ring.

[0006] Preferably, an electric cylinder is embedded in the center of the top surface of the base. The output shaft of the electric cylinder is fixedly connected to the center of the bottom surface of the lifting platform. When the electric cylinder is activated, the lifting platform can be raised and lowered under the action of the output shaft of the electric cylinder, thereby raising and lowering the storage cylinder so that the ultrasonic transducer can contact the liquid surface in the storage cylinder. A guide rod is fixedly connected to the bottom surface of the lifting platform. The bottom end of the guide rod passes through the base and is slidably connected to the base. When the lifting platform is raised and lowered, the guide rod can make the up and down movement of the lifting platform more stable.

[0007] Preferably, the side wall of the ultrasonic generator is provided with a fixing seat, and a connecting column is fixedly connected to the side wall of the fixing seat. The end of the connecting column away from the fixing seat is fixedly connected to the side wall of the upright plate. The ultrasonic generator is installed through the fixing seat. The ultrasonic generator can generate high-frequency electrical signals. The ultrasonic transducer can receive high-frequency electrical signals and convert them into mechanical vibrations, thereby generating ultrasonic waves to uniformly disperse the graphene conductive slurry in the storage cylinder.

[0008] Preferably, a guide ring is fixedly connected to the top surface of the gear ring, a ring body is rotatably connected to the side wall of the guide ring, and a fixing plate is fixedly connected to the side wall of the ring body. The side of the fixing plate away from the ring body is fixedly connected to the side wall of the upright plate. The ring body is installed through the fixing plate. When the motor is started, the gear rotates under the action of the motor output shaft. Through the meshing of the gear and the gear ring, and the cooperation of the guide ring and the ring body, the gear ring can rotate. The convex ring can cause the scraper to rotate. Figure 4 As shown, the bottom surface of the slide rail is provided with scale lines. When adjusting the position of the scraper, the scale lines facilitate reading the scraper's position adjustment, ensuring that the two scrapers are adjusted to the same distance. During scraper position adjustment, the outer wall of the scraper must be in contact with the inner wall of the storage cylinder. The rotating scraper scrapes the inner wall of the storage cylinder to prevent material from adhering to it. Simultaneously, the rotating scraper agitates the material at the edge of the storage cylinder to prevent uneven material distribution. The top surface of the slide sleeve is fitted with a threaded screw. The slide is connected to a fastening knob, the rod end of which extends into the sleeve opening and corresponds to the slide rail. The top surface of the fixing plate has a through mounting groove, and the motor is located in the mounting groove. Loosening the fastening knob separates the rod end from the slide rail, thereby adjusting the position of the slide sleeve and consequently the position of the scraper. The bottom surface of the slide rail has scale lines, which facilitate reading the scraper position adjustment to ensure that the two scrapers are adjusted at the same distance.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: it has a good uniform dispersion effect. The ultrasonic generator and ultrasonic transducer can generate ultrasonic waves to uniformly disperse the graphene conductive slurry in the storage cylinder, and can avoid sticking to the wall and uneven dispersion at the edges, thus effectively improving the dispersion effect. When the motor is started, the cooperation of gears and gear rings can make the scraper rotate to scrape the inner wall of the storage cylinder, so as to avoid the material adhering to the inner wall of the storage cylinder. At the same time, the rotating scraper can also stir the material at the edge of the storage cylinder to avoid uneven dispersion at the edge, thus improving the dispersion effect.

[0018] An electric cylinder 2 is embedded in the center of the top surface of the base 1, and the output shaft end of the electric cylinder 2 is fixedly connected to the center of the bottom surface of the lifting platform 3.

[0019] By adopting the above technical solution, the electric cylinder 2 is started, and the lifting platform 3 can be raised and lowered under the action of the output shaft of the electric cylinder 2, which in turn can raise and lower the storage cylinder 5 so that the ultrasonic transducer 8 can come into contact with the liquid surface in the storage cylinder 5.

[0020] A guide rod 4 is fixedly connected to the bottom surface of the lifting platform 3. The bottom end of the guide rod 4 passes through the base 1, and the guide rod 4 is slidably connected to the base 1.

[0021] By adopting the above technical solution, when the lifting platform 3 is raised or lowered, the guide rod 4 can make the lifting platform 3 move up and down more smoothly.

[0022] The ultrasonic generator 7 has a fixed base 9 on its side wall, and a connecting column 10 is fixedly connected to the side wall of the fixed base 9. The end of the connecting column 10 away from the fixed base 9 is fixedly connected to the side wall of the upright plate 6.

[0023] By adopting the above technical solution, the ultrasonic generator 7 is installed through the fixed base 9. The ultrasonic generator 7 can generate high-frequency electrical signals, and the ultrasonic transducer 8 can receive the high-frequency electrical signals and convert them into mechanical vibrations, thereby generating ultrasonic waves so that the graphene conductive slurry in the storage cylinder 5 can be uniformly dispersed.

[0024] A guide ring 15 is fixedly connected to the top surface of the toothed ring 16. A ring body 11 is rotatably connected to the side wall of the guide ring 15. A fixing plate 12 is fixedly connected to the side wall of the ring body 11. The side of the fixing plate 12 away from the ring body 11 is fixedly connected to the side wall of the upright plate 6.

[0025] By adopting the above technical solution, the ring body 11 is installed via the fixing plate 12. When the motor 13 is started, the gear 14 rotates under the action of the motor 13's output shaft. Through the meshing of the gear 14 and the gear ring 16, and the cooperation between the guide ring 15 and the ring body 11, the gear ring 16 can rotate. The convex ring 17 allows the scraper 20 to rotate. Figure 4 As shown, the bottom surface of the slide rail 18 is provided with scale lines. When adjusting the position of the scraper 20, the scale lines can be used to easily read the position adjustment of the scraper 20 so that the two scrapers 20 can be adjusted at the same distance. When adjusting the position of the scraper 20, the outer wall of the scraper 20 should be in contact with the inner wall of the storage cylinder 5. The rotating scraper 20 can scrape the inner wall of the storage cylinder 5 to prevent the material from adhering to the inner wall of the storage cylinder 5. At the same time, the rotating scraper 20 can also stir the material at the edge of the storage cylinder 5 to prevent the material at the edge from being unevenly dispersed.

A mounting groove is provided through the top surface of the fixing plate 12, and the motor 13 is located in the mounting groove.

[0027] By adopting the above technical solution, loosening the fastening knob 21 separates the rod end of the fastening knob 21 from the slide rail 18, thereby adjusting the position of the sliding sleeve 19, and subsequently adjusting the position of the scraper 20. The bottom surface of the slide rail 18 is provided with scale lines. When adjusting the position of the scraper 20, the scale lines facilitate the reading of the scraper 20's position adjustment, so that the two scrapers 20 can be adjusted at the same distance.

[0028] Working principle: When using this utility model, the storage cylinder 5 containing graphene conductive paste is fixed on the lifting platform 3, the fastening knob 21 is loosened so that the rod end of the fastening knob 21 is separated from the slide rail 18, and then the position of the sliding sleeve 19 is adjusted so that the outer wall of the scraper 20 contacts the inner wall of the storage cylinder 5.

[0029] Next, start the electric cylinder 2. The lifting platform 3 can be raised under the action of the output shaft of the electric cylinder 2, which in turn can raise the storage cylinder 5 so that the ultrasonic transducer 8 can come into contact with the liquid surface in the storage cylinder 5.

[0030] Then, a high-frequency electrical signal is generated by the ultrasonic generator 7, and the high-frequency electrical signal is received by the ultrasonic transducer 8 and converted into mechanical vibration, thereby generating ultrasonic waves to uniformly disperse the graphene conductive slurry in the storage cylinder 5.

[0031] At the same time, the motor 13 is started, and the gear 14 rotates under the action of the output shaft of the motor 13. Through the meshing of the gear 14 and the gear ring 16, and the cooperation of the guide ring 15 and the ring body 11, the gear ring 16 can rotate. The convex ring 17 can make the scraper 20 rotate to scrape the inner wall of the storage cylinder 5 to prevent the material from adhering to the inner wall of the storage cylinder 5. The rotating scraper 20 can also stir the material at the edge of the storage cylinder 5 to prevent the material at the edge from being unevenly dispersed.
