Description

Technical Field

[0001] This utility model relates to the field of preparation of a highly conductive graphene and carbon nanotube composite conductive paste. Background Technology

[0002] Carbon nanotubes, also known as buckytubes, can be viewed as a one-dimensional quantum material with a special structure (radial dimensions on the nanometer scale, axial dimensions on the micrometer scale, and both ends of the tube are basically sealed) formed by rolling up graphene sheets. Currently, the production of carbon nanotube conductive paste usually uses a sand milling and homogenization process to prepare composite conductive paste. In order to obtain a conductive paste with better conductivity, graphene can be added to carbon nanotubes.

[0003] The prior art, disclosed in CN214681170U, provides a device for preparing carbon nanotube conductive slurry, belonging to the technical field of carbon nanotube conductive slurry preparation equipment. It includes a vessel body with a sealed cap at the top and a feed inlet on the side wall of the vessel body, the feed inlet being close to the sealed cap. A stirring shaft is provided inside the vessel body, having a first end and a second end. The first end has an arc-shaped stirring blade adapted to the bottom of the vessel body, and the second end extends through the sealed cap and connects to a motor. The stirring shaft has several detachable stirring elements, and the angle between the stirring elements and the central axis of the stirring shaft is adjustable. A discharge port is provided at the bottom of the vessel body. This invention has the advantage of uniform dispersion.

[0004] The aforementioned patent mainly achieves the advantage of uniform dispersion of carbon nanotube conductive slurry by setting an adjustable-angle stirring element on the stirring shaft. However, in this method of dispersing carbon nanotube conductive slurry, since the stirring shaft is fixed and the carbon nanotube conductive slurry is a viscous fluid, the stirring element with small contact with the carbon nanotube conductive slurry cannot drive the entire carbon nanotube conductive slurry to be quickly stirred and mixed, which greatly reduces the practicality of the carbon nanotube conductive slurry preparation device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device for preparing a highly conductive graphene and carbon nanotube composite conductive paste, thus solving the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for preparing a highly conductive graphene and carbon nanotube composite conductive slurry, comprising a device body with an inlet at the top. An outlet ball valve for controlling the flow of the composite conductive slurry is fixedly installed at the end of the device body away from the inlet. A stirring assembly is rotatably mounted at the center of the device body. The stirring assembly includes a motor, and a side assembly is fixedly connected to the motor's output end. The side assembly includes a tube assembly, and a stirring core is fixedly installed in the middle of the tube assembly. The tube assembly is formed by splicing together multiple segments of curved and vertical pipes. The tube assembly's multi-segment configuration allows the entire tube assembly to rotate when the motor rotates, improving the internal structural integrity of the device for preparing the highly conductive graphene and carbon nanotube composite conductive slurry.

[0007] Furthermore, a stirring body is fixedly installed on the curved pipe of the tube assembly, and a connecting shaft for fixing to the motor output end is fixedly installed at the end of the tube assembly away from the outlet ball valve. This fixed connection at the end of the tube assembly away from the outlet ball valve significantly improves the robustness of the internal structural connections in the preparation device for the highly conductive graphene and carbon nanotube composite conductive slurry.

[0008] Furthermore, a bottom assembly is fixedly installed at the end of the tube assembly away from the motor. The bottom assembly includes a disc body, and a plurality of bottom stirring blades are fixedly installed on the outer side of the disc body. The bottom stirring blades have curved notches. These curved notches effectively prevent the composite conductive slurry in the preparation device of the highly conductive graphene and carbon nanotube composite conductive slurry from adhering to the bottom.

[0009] Furthermore, an inner groove is formed inside the disc body. A limiting disk is fixedly installed at the end of the tube assembly away from the motor. The limiting disk is located in the inner groove of the disc body. Several spring posts are fixedly installed at the bottom of the limiting disk, and the ends of the spring posts away from the limiting disk are fixed inside the disc body. The fact that the ends of the spring posts away from the limiting disk are fixed inside the disc body allows the limiting disk to move within the inner groove via the spring posts, improving the integrity of the internal structure of the device for preparing highly conductive graphene and carbon nanotube composite conductive paste.

[0010] Furthermore, the tube assembly has internally threaded holes at both ends, and the stirring assembly also includes a central shaft. Both ends of the central shaft are fixed in the internally threaded holes of the tube assembly, and a central plate for intermediate stirring is fixedly mounted on the central shaft. The central plate, used for intermediate stirring, stirs the highly conductive graphene and carbon nanotube composite conductive slurry in the middle of the preparation device, improving the thoroughness of internal stirring within the device.

[0011] Furthermore, the curved notch is a crescent shape formed above one side of the bottom stirring blade. This curved crescent shape allows the bottom stirring blade to move downwards continuously through the notch during stirring, improving the practicality of the apparatus for preparing highly conductive graphene and carbon nanotube composite conductive slurry.

[0012] Furthermore, the front cross-sections of both the auxiliary stirring body and the main stirring body are triangular. This triangular shape allows for smoother rotation of both bodies, significantly improving the practicality of the apparatus for preparing highly conductive graphene and carbon nanotube composite conductive slurry. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention improves the practicality of the device for preparing highly conductive graphene and carbon nanotube composite conductive slurry by setting the rotating shaft of the stirring assembly in a curved shape and setting the stirring blades on the stirring assembly in a triangular cross-section at the front end. This is achieved by setting the rotating shaft of the stirring assembly in a curved shape and setting the stirring blades on the stirring assembly in a triangular cross-section at the front end.

[0023] Example

[0024] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6This application provides a further detailed description. An apparatus for preparing a highly conductive graphene and carbon nanotube composite conductive slurry includes a device body 3. An inlet 2 is located at the top of the device body 3. An outlet ball valve 4 for controlling the flow of the composite conductive slurry is fixedly installed at the end of the device body 3 away from the inlet 2. A stirring assembly 1 is rotatably mounted at the center of the device body 3. The stirring assembly 1 includes a motor 11. A side assembly 14 is fixedly connected to the output end of the motor 11. The side assembly 14 includes a tube assembly 144. A stirring body 142 is fixedly installed in the middle of the tube assembly 144. The tube assembly 144 is formed by splicing multiple sections of curved and vertical pipes. A stirring side body 143 is fixedly installed on the curved pipes of the tube assembly 144. A connecting shaft 141 for fixing to the output end of the motor 11 is fixedly installed at the end of the tube assembly 144 away from the outlet ball valve 4. A bottom assembly 145 is fixedly installed at the end of the tube assembly 144 away from the motor 11. The bottom assembly 145 includes a disc 1453. Several bottom stirring blades 1451 are fixedly installed on the outer side of the disc body 1453. The bottom stirring blades 1451 have curved notches 1452. An inner groove 1454 is formed inside the disc body 1453. A limiting plate 1442 is fixedly installed at the end of the tube assembly 144 away from the motor 11. The limiting plate 1442 is located in the inner groove 1454 of the disc body 1453. Several spring posts 1443 are fixedly installed at the bottom of the limiting plate 1442, with the spring posts 1443 located away from the limiting plate 144. One end of 2 is fixed inside the disc body 1453. The upper and lower ends of the tube assembly 144 are provided with internal threaded holes 1441. The stirring assembly 1 also includes a central shaft 13. The two ends of the central shaft 13 are fixed in the internal threaded holes 1441 of the tube assembly 144. A central plate 12 for central stirring is fixedly installed on the central shaft 13. The curved notch 1452 is a curved crescent shape opened above one side of the bottom stirring blade 1451. The front cross-section of the stirring side body 143 and the stirring main body 142 is triangular.

[0025] Since the curved notch 1452 is located on the side of the bottom stirring blade 1451, when the disc 1453 rotates, the force generated by the rotation of the composite conductive slurry fluid will press the bottom stirring blade 1451 through the curved notch 1452, causing the bottom stirring blade 1451 to move downwards continuously. At this time, the spring column 1443, together with the upper limit plate 1442, causes the disc 1453 to move up and down during the rotation process, which greatly improves the thoroughness of stirring inside the preparation device of the high conductivity graphene and carbon nanotube composite conductive slurry.

[0026] Since the internal threaded hole 1441 has a threaded groove inside, and the upper and lower ends of the central shaft 13 also have threaded grooves, the entire tube assembly 144 is spliced ​​together from multiple sections of curved tubes and straight tubes. Since the two ends of the central shaft 13 have matching threads, the central shaft 13 can be fixedly installed in the internal threaded hole 1441 of the tube assembly 144 through the threads at both ends.

[0027] Since the front cross-sections of both the auxiliary stirring body 143 and the main stirring body 142 are triangular, when the auxiliary stirring body 143 and the main stirring body 142 rotate, the composite conductive slurry will disperse along the auxiliary stirring body 143 and the main stirring body 142, thereby reducing the resistance to the movement of the auxiliary stirring body 143 and the main stirring body 142 and improving the fullness and efficiency of the stirring inside the preparation device of the highly conductive graphene and carbon nanotube composite conductive slurry.

[0028] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the preparation device for highly conductive graphene and carbon nanotube composite conductive slurry are fixed by threads. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the figure. When using the preparation device, the user needs to add carbon nanotubes, a dispersant containing highly conductive graphene, and an organic solvent into the device body 3 through inlet 2. Then, the user starts motor 11, which directly rotates the central shaft 13 and the side assembly 14 counterclockwise. At this time, the material inside the device body 3 is dispersed by the triangular shape at the front end of the stirring side body 143 and the stirring main body 142. The stirring side body 143, the stirring main body 142, and the central plate... 12. The rotating component 1 is used to homogenize the material in the main body 3 quickly and thoroughly. During the rotation, the disc 1453 moves downward under the force of the bent notch 1452 on the bottom stirring blade 1451. At this time, the rebound force of the spring column 1443 will cause the disc 1453 to move up and down, so as to prevent the material in the main body 3 from settling to the bottom and to more thoroughly stir the material. After being stirred by the stirring component 1, the material in the main body 3 will form a composite conductive slurry. Finally, the composite conductive slurry is sent out by opening the outlet ball valve 4. This allows the preparation device for high conductivity graphene and carbon nanotube composite conductive slurry to quickly and thoroughly homogenize the composite conductive slurry during use, which greatly improves the practicality of the preparation device for high conductivity graphene and carbon nanotube composite conductive slurry.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
