Description
Technical Field
[0001] This utility model relates to the field of dispersion technology, specifically to a carbon nanotube conductive material dispersion device. Background Technology
[0002] Carbon nanotubes, as a type of nanomaterial, are lightweight and possess many exceptional mechanical, electrical, and chemical properties. Carbon nanotube slurry, also known as carbon nanotube conductive slurry, is a conductive slurry specifically designed for lithium batteries. It is made by mixing carbon nanotubes, dispersants, and solvents in a certain mass ratio. During the production of carbon nanotube conductive slurry, the semi-finished material poured in is prone to contain large agglomerates due to the influence of equipment and processes. These agglomerates need to be broken up and stirred in time; otherwise, the performance of the finished carbon nanotube slurry itself may be reduced.
[0003] Based on the above, the inventors have discovered the following problems: the current preparation process of carbon nanotube conductive materials requires adding the dispersant to the dispersion device in one or multiple batches and stirring to mix it evenly. However, many current dispersion devices do not have the function of quantitatively adding dispersant. Too little dispersant cannot completely cover the particle surface, resulting in unstable dispersion; too much may cause interactions between dispersant molecules, which in turn affects the dispersion performance. This necessitates weighing the dispersant in advance each time before adding it to the dispersion device, thereby reducing work efficiency.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a carbon nanotube conductive material dispersion device in order to achieve a more practical purpose. Utility Model Content
[0005] The purpose of this invention is to provide a carbon nanotube conductive material dispersion device to solve the problems mentioned in the background art.
[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0007] A carbon nanotube conductive material dispersion device includes a support component, a dispersion component, and a feeding component. The dispersion component is disposed above the support component, and the feeding component is disposed outside the dispersion component. The support component is used to stably support the dispersion component. The dispersion component includes a cylindrical body and is used to disperse the carbon nanotube conductive material. The feeding component is used to add a surfactant to the interior of the dispersion component. The feeding component includes a connecting plate with an installation hole inside. A storage cylinder is connected inside the installation hole. A solenoid valve is installed on the top surface of the storage cylinder. The two ends of the solenoid valve are respectively connected to a first connecting pipe and a second connecting pipe. The first connecting pipe extends through the storage cylinder into the interior at the end away from the solenoid valve. A flow meter is installed at the end of the second connecting pipe away from the solenoid valve. One end of the flow meter is connected to a third connecting pipe. A first pump is installed on one side of the top surface of the cylindrical body. The inlet end of the first pump is connected to the end of the third connecting pipe away from the flow meter.
[0008] Furthermore, the interior of the storage cylinder is filled with a surfactant, and a feed pipe is connected to the back of the storage cylinder near the upper end. A first valve is installed at the end of the feed pipe away from the storage cylinder.
[0009] The beneficial effect of adopting the above-mentioned further solution is that by filling the inside of the storage cylinder with surfactant, when the solenoid valve is opened, the first connecting pipe, the second connecting pipe and the third connecting pipe are connected, and then the first pump is started to pump the surfactant in the storage cylinder into the cylinder body, so as to facilitate the mixing of carbon nanotube conductive material and surfactant, improve dispersion efficiency. By connecting the feed pipe to the back of the storage cylinder, when the first valve is opened, the surfactant can be injected into the storage cylinder through the feed pipe using external equipment, so as to avoid the low surfactant content in the storage cylinder affecting the quantitative addition of surfactant.
[0010] Furthermore, a second pump is installed on the top surface of the cylinder opposite to the first pump, and the outlet ends of both the second pump and the first pump extend through the cylinder into the interior.
[0011] The beneficial effect of adopting the above-mentioned further solution is that, by setting up a second pump, the outlet of the container storing carbon nanotube conductive material is connected to the inlet of the second pump through a pipe. When the second pump is started, the second pump pumps the carbon nanotube conductive material in the container into the cylinder.
[0012] Furthermore, a hollow rod is connected to the top of the inner part of the cylinder via a bearing. Several dispersing rods are connected to both sides of the outer part of the hollow rod. The dispersing rods are distributed in a straight line at equal distances. A rotating rod is provided inside the hollow rod. The length of the rotating rod is greater than the length of the hollow rod. A dispersing disk is connected to the bottom end of the rotating rod. Several dispersing blades are connected to the outer wall of the dispersing disk. The dispersing blades are distributed in a ring at equal distances.
[0013] The beneficial effect of adopting the above-mentioned further solution is that, by setting a hollow rod and a rotating rod, with the rotating rod located inside the hollow rod and a certain distance between the inner wall of the hollow rod and the outer wall of the rotating rod, and since several dispersing rods are connected to the outer sides of the hollow rod, and the bottom end of the rotating rod is connected to a dispersing disk with dispersing blades connected to the outer wall of the dispersing disk, when the hollow rod and the rotating rod rotate respectively, under the action of the dispersing rods, the dispersing disk, and the dispersing blades, the carbon nanotube conductive material and the surfactant in the cylinder are mixed. The surfactant molecules will be adsorbed on the surface of the carbon nanotubes, reducing their surface energy and weakening the interaction force between the carbon nanotube conductive materials, thereby achieving dispersion.
[0014] Furthermore, a mounting box is connected to the center of the top surface of the cylinder. The top ends of both the hollow rod and the rotating rod extend through the mounting box into the interior. The top end of the rotating rod is connected to the inner top end of the mounting box via a bearing. A first bevel gear is sleeved on the outside of the hollow rod, and a second bevel gear is sleeved on the outside of the rotating rod. A servo motor is mounted on the front of the mounting box. The output end of the servo motor extends through the mounting box into the interior, and the output end of the servo motor is connected to a third bevel gear. The outer sides of the third bevel gear mesh with the first bevel gear and the second bevel gear, respectively.
[0015] The beneficial effect of adopting the above-mentioned further solution is that by setting a servo motor, when the servo motor is started, it is easy to drive the third bevel gear to rotate. Since the third bevel gear meshes with the first bevel gear and the second bevel gear on its two sides respectively, the hollow rod and the rotating rod rotate in opposite directions.
[0016] Furthermore, a discharge pipe is connected to one side of the bottom end of the cylinder, and a second valve is installed at the end of the discharge pipe away from the cylinder.
[0017] The beneficial effect of adopting the above-mentioned further solution is that by setting up a discharge pipe and setting a second valve at one end of the discharge pipe, the collection container is placed at the discharge pipe. When the second valve is opened, the carbon nanotube conductive material after dispersion treatment is discharged through the discharge pipe.
[0018] Furthermore, the support assembly includes a base plate, with support plates connected to both sides of the top surface of the base plate, a hollow ring connecting a pair of support plates, a cylinder disposed inside the hollow ring, and the outer wall of the cylinder being fixedly connected to the inner wall of the hollow ring. Mounting holes are provided at the four corners of the interior of the base plate.
[0019] The advantage of adopting the above-mentioned further solution is that by opening mounting holes at the four internal corners of the base plate, it is easy to install the base plate in a designated position, and the distribution components are stably supported by the support plate and hollow ring.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This carbon nanotube conductive material dispersion device connects the outlet of a container storing the carbon nanotube conductive material to the inlet of a second pump via a pipe. When the second pump is started, it pumps the carbon nanotube conductive material from the container into the cylinder. A surfactant is then filled into the storage cylinder. When the solenoid valve is opened, the first, second, and third connecting pipes are connected. The first pump is then started, pumping the surfactant from the storage cylinder into the cylinder. Simultaneously, a flow meter monitors the amount of surfactant passing through. Once the required level is reached, the solenoid valve is closed, de-connecting the first, second, and third connecting pipes, ensuring that the amount of surfactant entering the cylinder meets the standard. To achieve quantitative feeding, when the servo motor is started, it facilitates the rotation of the third bevel gear. Since the third bevel gear meshes with the first and second bevel gears on its two sides, the hollow rod and the rotating rod rotate in opposite directions. Because the rotating rod is located inside the hollow rod, there is a certain distance between the inner wall of the hollow rod and the outer wall of the rotating rod. Several dispersing rods are connected to the outer sides of the hollow rod, and the bottom end of the rotating rod is connected to a dispersing disk, with dispersing blades connected to the outer wall of the dispersing disk. When the hollow rod and the rotating rod rotate respectively, under the action of the dispersing rods, the dispersing disk, and the dispersing blades, the carbon nanotube conductive material and the surfactant in the cylinder are mixed. The surfactant molecules are adsorbed on the surface of the carbon nanotubes, reducing their surface energy, weakening the interaction force between the carbon nanotube conductive materials, and improving the dispersion efficiency.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-5This utility model provides a technical solution: a carbon nanotube conductive material dispersion device, including a support component 1, a dispersion component 2, and a feeding component 3. The dispersion component 2 is disposed above the support component 1, and the feeding component 3 is disposed outside the dispersion component 2. The support component 1 is used to stably support the dispersion component 2. The dispersion component 2 includes a cylinder 21 and is used to disperse the carbon nanotube conductive material. The feeding component 3 is used to add a surfactant to the inside of the dispersion component 2. The feeding component 3 includes a connecting plate 31, and the inside of the connecting plate 31 has an installation hole. A storage cylinder 32 is connected inside the installation hole. A solenoid valve 34 is installed on the top surface of the storage cylinder 32. The two ends of the solenoid valve 34 are respectively connected to a first connecting pipe 33 and a second connecting pipe. The first connecting pipe 33 extends through the storage cylinder 32 into the interior at the end away from the solenoid valve 34. A flow meter 35 is installed at the end of the second connecting pipe away from the solenoid valve 34. One end of the flow meter 35 is connected to a third connecting pipe 36. A first pump 212 is installed on one side of the top surface of the cylinder 21. The inlet end is connected to the end of the third connecting pipe 36 away from the flow meter 35. The inside of the storage cylinder 32 is filled with surfactant. The back of the storage cylinder 32 is connected to the feed pipe near the top. The feed pipe is equipped with a first valve at the end away from the storage cylinder 32. When the solenoid valve 34 is opened, the first connecting pipe 33, the second connecting pipe and the third connecting pipe 36 are connected. Then the first pump 212 is started to pump the surfactant in the storage cylinder 32 into the cylinder 21. At the same time, the flow meter 35 is used to monitor the amount of surfactant passing through. After it reaches the required level, the solenoid valve 34 is closed so that the first connecting pipe 33, the second connecting pipe and the third connecting pipe 36 are no longer connected. This ensures that the amount of surfactant entering the cylinder 21 meets the standard, thereby achieving the purpose of quantitative feeding. By connecting the feed pipe to the back of the storage cylinder 32, when the first valve is opened, it is possible to use external equipment to inject surfactant into the storage cylinder 32 through the feed pipe, avoiding the problem of insufficient surfactant content in the storage cylinder 32 affecting the quantitative feeding of surfactant.
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-5This utility model provides a technical solution: A second pump 213 is installed on the top surface of the cylinder 21 opposite to the first pump 212. The liquid outlet ends of both the second pump 213 and the first pump 212 extend through the cylinder 21 into the interior. A hollow rod 22 is connected to the top of the interior of the cylinder 21 via a bearing. Several dispersing rods 23 are connected to both sides of the outer side of the hollow rod 22. The dispersing rods 23 are distributed in a straight line at equal intervals. A rotating rod 25 is provided inside the hollow rod 22. The length of the rotating rod 25 is greater than the length of the hollow rod 22, and a dispersing disk 26 is connected to the bottom end of the rotating rod 25. Several dispersing blades 27 are connected to the outer wall of the dispersing disk 26. The dispersing blades 27 are distributed in a ring at equal intervals. A mounting box 24 is connected to the center of the top surface of the cylinder 21. The top ends of both the hollow rod 22 and the rotating rod 25 extend through the mounting box 24 into the interior. The top end of the rotating rod 25 is connected to the inner top end of the mounting box 24 via a bearing. A first bevel gear 28 is sleeved on the outside of the hollow rod 22, and a second bevel gear 29 is sleeved on the outside of the rotating rod 25. A servo motor 210 is mounted on the front of the mounting box 24. The output end of the servo motor 210 extends through the mounting box 24 into the interior, and the output end of the servo motor 210 is connected to a third bevel gear 211. The outer sides of the third bevel gear 211 mesh with the first bevel gear 28 and the second bevel gear 29, respectively. A discharge pipe 214 is connected to one side of the bottom end of the cylinder 21. A second valve is installed at the end of the discharge pipe 214 away from the cylinder 21. The support assembly 1 includes a bottom... The bottom plate 11 has support plates 12 connected to both sides of its top surface. A hollow ring 13 is connected between a pair of support plates 12. The cylinder 21 is located inside the hollow ring 13, and the outer wall of the cylinder 21 is fixedly connected to the inner wall of the hollow ring 13. Mounting holes are provided at the four corners of the bottom plate 11. By setting a second pump 213, the outlet of the container storing carbon nanotube conductive material is connected to the inlet of the second pump 213 through a pipe. When the second pump 213 is started, it pumps the carbon nanotube conductive material in the container into the cylinder 21. By setting a servo motor 210, when the servo motor 210 is started, it is easy to drive the third bevel gear 211 to rotate. Since the third bevel gear 211 is connected to the first bevel gear 28 and the second bevel gear 211 on both sides respectively, the third bevel gear 211 is connected to the first bevel gear 28 and the second bevel gear 211 on both sides respectively. Gear 29 meshes, causing the hollow rod 22 and the rotating rod 25 to rotate in opposite directions. The hollow rod 22 and the rotating rod 25 are positioned inside the hollow rod 22, with a certain distance between the inner wall of the hollow rod 22 and the outer wall of the rotating rod 25. Several dispersing rods 23 are connected to the outer sides of the hollow rod 22, and the bottom end of the rotating rod 25 is connected to a dispersing disk 26, with dispersing blades 27 connected to the outer wall of the dispersing disk 26. When the hollow rod 22 and the rotating rod 25 rotate, the carbon nanotube conductive material and the surfactant inside the cylinder 21 are mixed under the action of the dispersing rods 23, the dispersing disk 26, and the dispersing blades 27. The surfactant molecules adsorb onto the surface of the carbon nanotubes, reducing their surface energy and weakening the interaction forces between the carbon nanotube conductive materials.This achieves dispersion by setting up a discharge pipe 214, with a second valve at one end of the discharge pipe 214. A collection container is placed at the discharge pipe 214, and when the second valve is opened, the dispersed carbon nanotube conductive material is discharged through the discharge pipe 214.
[0031] Specifically, the working principle of this carbon nanotube conductive material dispersion device is as follows: During use, the base plate 11 is installed in a designated position, and the dispersion component 2 is stably supported by the support plate 12 and hollow ring 13. The outlet of the container storing the carbon nanotube conductive material is connected to the inlet of the second pump 213 via a pipe. When the second pump 213 is started, it pumps the carbon nanotube conductive material from the container into the cylinder 21. Surfactants are filled inside the storage cylinder 32. When the solenoid valve 34 is opened, the first connecting pipe 33, the second connecting pipe, and the third connecting pipe 36 are connected. Then, the first pump 212 is started, pumping the surfactant from the storage cylinder 32 into the cylinder 21. Simultaneously, the flow meter 35 monitors the amount of surfactant passing through. Once the required amount is reached, the solenoid valve 34 is closed, de-connecting the first connecting pipe 33, the second connecting pipe, and the third connecting pipe 36, thus de-connecting the surfactant entering the cylinder 21. The amount of agent meets the standard, thus achieving the purpose of quantitative feeding. When the servo motor 210 is started, it facilitates the rotation of the third bevel gear 211. Since the third bevel gear 211 meshes with the first bevel gear 28 and the second bevel gear 29 on its two sides, the hollow rod 22 and the rotating rod 25 rotate in opposite directions. Since the rotating rod 25 is located inside the hollow rod 22, there is a certain distance between the inner wall of the hollow rod 22 and the outer wall of the rotating rod 25. Since several dispersing rods 23 are connected to the outer sides of the hollow rod 22, the bottom end of the rotating rod 25 is connected to the dispersing disk 26, and the outer wall of the dispersing disk 26 is connected to the dispersing blades 27, when the hollow rod 22 and the rotating rod 25 rotate respectively, under the action of the dispersing rods 23, the dispersing disk 26 and the dispersing blades 27, the carbon nanotube conductive material and the surfactant in the cylinder 21 are mixed. The surfactant molecules will be adsorbed on the surface of the carbon nanotubes, reducing their surface energy, weakening the interaction force between the carbon nanotube conductive materials, and improving the dispersion efficiency.
