Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and in particular relates to a slurry dispersion plate, a dispersion tank and a slurry mixing system. Background Art

[0002] In the manufacturing process of batteries, material mixing is a very critical link, which directly affects the performance and quality of batteries. Material mixing mainly involves mixing active substances, conductive agents and other additives in a certain proportion and order to achieve the best electrochemical performance. In the material mixing process, the mixer plays a vital role.

[0003] There are two main types of existing mixers: one is a stirring mixer and the other is a centrifugal mixer. A stirring mixer mixes the materials together by the rotation of the stirring paddle. A centrifugal mixer generates a strong centrifugal force through the high-speed rotating rotor, so that the materials are dispersed and mixed together under the action of the centrifugal force.

[0004] In the prior art, most centrifugal mixers disperse and mix materials through high-speed rotating dispersion disks. Although this can meet basic mixing needs, the dispersion and mixing efficiency is low due to the relatively simple structural design of most dispersion disks, which cannot meet large-scale production needs. When a large amount of material is added to the mixer, it is easy to cause uneven mixing of the materials and fail to meet the use requirements, which not only increases production costs but also reduces production efficiency. Utility Model Content

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] In the description of the present application, it should be noted that the terms used here are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0040] Embodiment 1:

[0041] This embodiment provides a slurry dispersion disk, comprising:

[0042] A disk body 41, wherein a plurality of first through holes 43 are formed on the disk body 41;

[0043] A dispersion member, which is disposed on an end surface of one side of the disk body 41;

[0044] The scraper 42 is disposed on the end surface of the other side of the disc body 41 , and a plurality of second through holes 44 are formed on the scraper 42 .

[0045] In the present technical solution, the slurry dispersion disk is installed on the dispersion shaft in the dispersion tank 4 for use, and multiple slurry dispersion disks can be installed on the dispersion shaft, and multiple slurry dispersion disks are arranged along the axial direction of the dispersion shaft. The working principle of the slurry dispersion disk is that the dispersion disk is driven by the dispersion shaft to rotate to generate centrifugal force, so that the material in the dispersion tank 4 rotates and flows, and at the same time, the dispersion parts on the dispersion disk will perform high-speed shearing and collision on the material, so that the material is evenly dispersed.

[0046] A plurality of first through holes 43 are provided on the disc body 41. The first through holes 43 may be evenly distributed or unevenly distributed. When the gravity of the material after being dispersed by the dispersion disc meets the condition that the centrifugal force is greater than the gravity, the material will flow downward through the first through holes 43 and then flow to the next slurry dispersion disc for dispersion. By arranging a plurality of slurry dispersion discs in the dispersion tank 4, the dispersion effect on the material is enhanced. At the same time, the first through holes 43 on the dispersion disc can also further disperse the material, thereby effectively improving the material dispersion efficiency.

[0047] A scraper 42 is also provided on the bottom of the disc body 41. When the dispersion disc rotates at a high speed, the scraper 42 can scrape the material flowing out of the first through hole 43 to the central position of the next dispersion disc as much as possible, thereby reducing the amount of material flowing down along the gap between the tank wall and the dispersion disc. When the scraper 42 scrapes the material flowing out of the first through hole 43, part of the material will pass through the second through hole 44 of the scraper 42. With the high-speed rotation of the scraper 42, the material can be further dispersed, thereby effectively enhancing the dispersion effect and improving the material dispersion efficiency.

[0048] Embodiment 2:

[0049] This embodiment provides a slurry dispersion disk, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0050] Further, the dispersed parts include:

[0051] A plurality of groups of dispersion modules are arranged in a circular array along the circumferential direction of the disk body 41 .

[0052] Furthermore, the decentralized module includes:

[0053] A plurality of dispersed columns 45 are arranged along the radial direction of the disk body 41 .

[0054] In this technical solution, if Figure 1 As shown, a plurality of dispersion columns 45 are arranged on the end face of one side of the disk body 41 and are in an arc shape. Through this structural design, when the slurry dispersion disk is performing high-speed dispersion, the dispersion columns 45 at different positions on the slurry dispersion disk from the axis can provide different dispersion linear speeds for the slurry dispersion disk, thereby greatly enhancing the dispersion effect on the material, and then effectively improving the dispersion efficiency, and having high practicality.

[0055] Furthermore, in each dispersion module, the height of the plurality of dispersion columns gradually increases in the direction away from the center of the disk. Through this structural design, the layered dispersion column arrangement can reduce the dead angle or local uneven mixing problems that may occur during the mixing process, ensure that various materials can be evenly mixed and dispersed, effectively enhance the mixing and dispersion effect, and improve the mixing efficiency.

[0056] Embodiment 3:

[0057] This embodiment provides a slurry dispersion disk, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0058] Furthermore, a plurality of first through holes 43 are respectively located between two adjacent groups of dispersion modules.

[0059] In the present technical solution, through this structural design, the first through holes 43 are evenly distributed on the disk body 41, so that the material can flow to the next slurry dispersion disk in an orderly and uniform manner. In addition, it can also reduce the stress concentration when the slurry dispersion disk disperses the material, enhance the bending and torsion resistance of the slurry dispersion disk, and improve the durability and service life of the slurry dispersion disk.

[0060] Embodiment 4:

[0061] This embodiment provides a slurry dispersion disk, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0062] Furthermore, the scraper 42 is an arc-shaped structure.

[0063] In the present technical solution, the structural strength of the scraper 42 is enhanced through this structural design, so that when the scraper 42 scrapes and collects the material flowing out of the first through hole 43, the pressure of the scraped material can be more evenly distributed on the scraper 42, avoiding stress concentration that causes deformation and damage of the scraper 42, extending the service life of the dispersion disk, and effectively improving durability.

[0064] Embodiment 5:

[0065] This embodiment provides a slurry dispersion disk, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0066] Furthermore, there are a plurality of scrapers 42, and the plurality of scrapers 42 are arranged in a ring array.

[0067] In this technical solution, by increasing the number of scrapers 42 on the dispersion disk, the scraping effect on the material flowing out of the first through hole 43 is enhanced to ensure that the material can fall on the central position of the next dispersion disk, further reducing the amount of material flowing down along the gap between the tank wall and the dispersion disk, thereby improving the dispersion effect.

[0068] Embodiment 6:

[0069] This embodiment provides a dispersion tank, which, in addition to comprising the slurry dispersion disk described in any one of the above embodiments 1-5, further comprises:

[0070] Tank;

[0071] A dispersion shaft, the dispersion shaft is rotatably mounted in the tank body;

[0072] A driving member, which is installed on the tank body and is used to drive the dispersion shaft to rotate;

[0073] There are several slurry dispersion discs, which are installed on the dispersion shaft along the axial direction.

[0074] In this technical solution, the dispersion shaft is installed in the tank body, the slurry dispersion disk is installed on the dispersion shaft, and the driving member is installed on the tank body. The driving member can be a motor, and the output end of the motor is connected to the dispersion shaft. Starting the motor controls the rotation of the dispersion shaft to drive the slurry dispersion disk to rotate and disperse the material.

[0075] The number of slurry dispersion disks is set according to the specific materials to be processed, and the size of the first through hole 43 on the slurry dispersion disk can be designed according to the properties of the material. The size of the first through hole 43 of the slurry dispersion disk at different positions gradually decreases from top to bottom with the height position. Through this structural design, the dispersion effect on the material is further enhanced, the material dispersion efficiency is improved, and the multi-layer slurry dispersion disk design can effectively increase the material processing capacity of the dispersion tank 4 to meet greater production capacity requirements, while reducing the placement and use of the dispersion tank 4 and saving floor space.

[0076] Embodiment 7:

[0077] This embodiment provides a slurry mixing system, which, in addition to the dispersion tank described in the above embodiment 6, also includes:

[0078] Material metering tank 1, material metering tank 1 is used to hold materials to be mixed;

[0080] A first diaphragm pump 3, the first diaphragm pump 3 is used to transport the material in the premixing tank 2 to the dispersion tank 4;

[0081] A buffer tank 5, which is arranged downstream of the dispersion tank 4 and is used to store dispersed materials;

[0082] The second diaphragm pump 6 is used to output the material in the buffer tank 5.

[0083] In the present technical solution, there can be two material metering tanks 1, one material metering tank 1 is a powder metering tank for storing powdered materials, and the other material metering tank 1 is a liquid metering tank for storing liquid materials. The materials in the two material metering tanks 1 are transported to the premixing tank 2 for mixing and storage. The material metering tanks 1 can be used to accurately measure the flow rate of the materials, thereby accurately controlling the mixing ratio of the two materials.

[0084] After the two materials are mixed and prefabricated in the premixing tank 2, they are then transported to the dispersion tank 4 through the first diaphragm pump 3 to disperse the mixed prefabricated materials. After the dispersion treatment, the materials are transported to the buffer tank 5 for storage, and the parameters of the materials are tested. If the parameters of the materials are qualified, it means that the dispersion meets the standards. Finally, they are shipped and used through the second diaphragm pump 6.

[0085] Furthermore, it also includes a return pipe, and the two ends of the return pipe are respectively connected to the buffer tank 5 and the dispersion tank 4. When the material parameter test in the buffer tank 5 fails, indicating that the dispersion is not up to standard, the material is transferred back to the dispersion tank 4 along the return pipe through the second diaphragm pump 6 for circulation and dispersion treatment, ensuring that the material can be completely dispersed to meet the use requirements. In summary, the slurry mixing system can perform uninterrupted slurry mixing and can meet the dry, wet, and semi-dry pulping processes, and is highly practical.
