Description

Technical Field

[0001] This utility model relates to the field of sodium-ion battery technology, and in particular to a device for preparing battery cathode material. Background Technology

[0002] Sodium-ion batteries are a type of rechargeable battery. Their working principle mainly relies on the movement of sodium ions between the positive and negative electrodes to achieve charging and discharging. During charging, sodium ions are inserted from the positive electrode material into the negative electrode material, and during discharging, they are extracted from the negative electrode material and return to the positive electrode material.

[0003] Existing sodium-ion cathode materials are generally prepared inside a container. However, unreacted substances and byproducts easily adhere to the inner wall of the container, which not only affects the cleanliness of the container but also potentially impacts the purity and quality of materials prepared in subsequent batches. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a battery cathode material preparation device.

[0005] The present invention discloses a battery cathode material preparation device, comprising a tank 1, and further comprising:

[0006] A cleaning assembly for cleaning the inner wall of the tank 1 includes an annular scraper 8 that is in contact with the inner wall of the bottom of the tank 1. A connecting rod 7 is fixed to the upper end of the annular scraper 8 and the connecting rod 7 is disposed through the upper end face of the tank 1.

[0007] A limiting component is fixed to one side of the upper end of the tank 1 near the connecting rod 7, and is used to limit the vertical degree of freedom of the connecting rod 7.

[0008] In this way, the vertical freedom of the connecting rod 7 is first restricted by the limiting component, and then the connecting rod 7 is pulled up and down to drive the annular scraper 8 at the bottom to clean the inner wall of the tank 1, so that the residue or attachment on the inner wall is effectively removed, thereby improving the cleanliness of the tank and the quality of the material during the next material preparation.

[0009] Preferably, the limiting component includes a hollow box 9, which is fixed to the upper side of the tank 1 near the connecting rod 7. A cover plate 21 is fixed to the upper end of the hollow box 9. A first through slot 10 is provided on the top of the cover plate 21. A drive rod 11 is slidably connected inside the first through slot 10. A push block 12 is fixed to the bottom of the drive rod 11. One end of the push block 12 abuts against a force receiving block 13. The surfaces of the push block 12 and the force receiving block 13 that abut against each other are both provided with arc-shaped surfaces. A plug-in rod 15 is fixed to the side of the force receiving block 13 facing the connecting rod 7. A plug-in hole 16 is provided at one end of the connecting rod 7. 5. The rod is inserted into the insertion hole 16 through the second through slot 14 opened in the inner wall of the hollow box 9. A return spring 17 is sleeved on the insertion rod 15 located between the force block 13 and the inner wall of the hollow box 9. A thrust spring 18 is fixedly connected to the top of the push block 12. The top of the thrust spring 18 is fixedly connected to the bottom of the cover plate 21. Pull the drive rod 11 upward. The drive rod 11 drives the push block 12 to move upward and release the abutment relationship with the force block 13. Then the return spring 17 restores its elasticity and drives the force block 13, and then drives the insertion rod 15 to be pulled out of the insertion hole 16, releasing the limit of the connecting rod 7.

[0010] The push spring 18 provides a stable and downward force when the push block 12 and the force-receiving block 13 come into contact, making the insertion rod 15 more stable in the insertion hole 16.

[0011] In addition, the contact surfaces of the pushing block 12 and the force-receiving block 13 are both designed as arc surfaces, which not only increases the contact area between the two, but also improves the efficiency and smoothness of the transmission. When the pushing block 12 and the force-receiving block 13 come into contact with each other and apply force, the presence of the arc surface makes the pressure distribution at the contact point more uniform, making the contact between the two smoother.

[0012] Preferably, the inner wall of the hollow box 9 has limit grooves 19 on both sides, and the force-bearing block 13 has limit blocks 20 fixedly connected to both sides, with the limit blocks 20 extending into the limit grooves 19 and sliding.

[0013] The combined use of the limiting groove 19 and the limiting block 20 provides a clear trajectory for the movement of the force-bearing block 13 within the hollow box 9, ensuring that the force-bearing block 13 can move stably and smoothly along the predetermined path when subjected to external force.

[0014] Preferably, both sides of the inner wall of the first through slot 10 are provided with sliding grooves 22, and both sides of the drive rod 11 are fixedly connected with sliders 23, which extend into the sliding grooves 22 for sliding connection.

[0015] Preferably, the upper end of the tank body 1 is provided with a through groove 6, and the upper part of the connecting rod 7 is slidably connected to the inside of the through groove 6.

[0016] Preferably, a plurality of support legs 2 are fixedly connected to the surface of the tank body 1, a feed inlet 3 is installed on the top of the tank body 1, a motor 4 is installed on the top of the tank body 1, and a stirrer 5 is rotatably connected to the output end of the motor 4.

[0017] In summary, this utility model has the following beneficial effects: firstly, the vertical freedom of the connecting rod is restricted by the limiting component, and then the connecting rod is pulled up and down, which drives the annular scraper at the bottom to clean the inner wall of the tank, so that the residue or attachment on the inner wall is effectively removed, thereby improving the cleanliness of the tank and the quality of the material during the next material preparation.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] like Figure 1-6 As shown, the battery cathode material preparation apparatus proposed in this embodiment includes a tank 1, and further includes:

[0029] A cleaning assembly for cleaning the inner wall of tank 1 includes an annular scraper 8 that is in contact with the inner wall of the bottom of tank 1, and a connecting rod 7 is fixed to the upper end of the annular scraper 8. The connecting rod 7 is disposed through the upper end face of tank 1.

[0030] Specifically, a through groove 6 is provided at the upper end of the tank body 1, and the upper part of the connecting rod 7 is slidably connected to the inside of the through groove 6.

[0031] A limiting component is fixed to one side of the upper end of the tank 1 near the connecting rod 7 to limit the vertical degree of freedom of the connecting rod 7.

[0032] In this way, the vertical freedom of the connecting rod 7 is first restricted by the limiting component, and then the connecting rod 7 is pulled up and down to drive the annular scraper 8 at the bottom to clean the inner wall of the tank 1, so that the residue or attachment on the inner wall is effectively removed, thereby improving the cleanliness of the tank and the quality of the material during the next material preparation.

[0033] Furthermore, such as Figure 2-5As shown, the limiting component includes a hollow box 9, which is fixed to the upper side of the tank 1 near the connecting rod 7. A cover plate 21 is fixed to the upper end of the hollow box 9. A first through slot 10 is opened on the top of the cover plate 21. A drive rod 11 is slidably connected inside the first through slot 10. A push block 12 is fixed to the bottom of the drive rod 11. One end of the push block 12 abuts against a force receiving block 13. The surfaces of the push block 12 and the force receiving block 13 that abut against each other are both provided with arc-shaped surfaces. A plug-in rod 15 is fixed to the side of the force receiving block 13 facing the connecting rod 7. A plug hole 16 is opened at one end of the connecting rod 7. The plug-in rod 15 passes through a hole opened on the inner wall of the hollow box 9. The second through slot 14 is inserted into the insertion hole 16. A return spring 17 is sleeved on the insertion rod 15 located between the force block 13 and the inner wall of the hollow box 9 (when the insertion rod 15 is inserted into the insertion hole 16, the return spring 17 is compressed). A thrust spring 18 is fixedly connected to the top of the push block 12. The top of the thrust spring 18 is fixedly connected to the bottom of the cover plate 21. Pulling the drive rod 11 upward causes the drive rod 11 to move the push block 12 upward, releasing the contact relationship with the force block 13. Then, the return spring 17 restores its elasticity, drives the force block 13, and then drives the insertion rod 15 to be pulled out of the insertion hole 16, releasing the limit of the connecting rod 7.

[0034] The push spring 18 provides a stable and downward force when the push block 12 and the force-receiving block 13 come into contact, making the insertion rod 15 more stable in the insertion hole 16.

[0035] In addition, the contact surfaces of the pushing block 12 and the force-receiving block 13 are both designed as arc surfaces, which not only increases the contact area between the two, but also improves the efficiency and smoothness of the transmission. When the pushing block 12 and the force-receiving block 13 come into contact with each other and apply force, the presence of the arc surface makes the pressure distribution at the contact point more uniform, making the contact between the two smoother.

[0036] It should be noted that the outer diameter of the plug rod 15 is adapted to the internal shape of the socket 16. The tight fit between the plug rod 15 and the socket 16 ensures a firm connection between them and prevents them from loosening, thereby greatly enhancing the stability of the overall structure.

[0037] Furthermore, limiting grooves 19 are provided on both sides of the inner wall of the hollow box 9, and limiting blocks 20 are fixedly connected to both sides of the force-bearing block 13. The limiting blocks 20 extend into the limiting grooves 19 and slide. The cooperation between the limiting grooves 19 and the limiting blocks 20 provides a clear trajectory for the movement of the force-bearing block 13 within the hollow box 9, ensuring that the force-bearing block 13 can move stably and smoothly along the predetermined path when subjected to external forces.

[0038] In summary, when it is necessary to clean the inner wall of tank 1, first pull the drive rod 11 upwards to cause the drive rod 11 to drive the push block 12 to disengage from the force block 13. At this time, the return spring 17 restores its deformation and drives the force block 13 away from the direction of tank 1, thereby causing the plug rod 15 to be pulled out from the plug hole 16. At this time, the limitation of the vertical degree of freedom of the connecting rod is released. Then, by moving the connecting rod 7 up and down, the connecting rod 7 drives the bottom annular scraper 8 to move up and down to clean the inner wall of tank 1, so that the residue or attachment on the inner wall is effectively removed, improving the cleanliness of tank 1 and the quality of materials in the next material preparation.

[0039] In this embodiment, refer to Figure 6 As shown, sliding grooves 22 are provided on both sides of the inner wall of the first through slot 10, and sliders 23 are fixedly connected to both sides of the drive rod 11. The sliders 23 extend into the sliding grooves 22 to form a sliding fit, so that the drive rod 11 can move more stably and smoothly along the first through slot 10.

[0040] It should be noted that, as Figure 2 As shown, multiple support legs 2 are fixedly connected to the surface of the tank body 1, a feed inlet 3 is installed on the top of the tank body 1, a motor 4 is installed on the top of the tank body 1, and an agitator 5 is rotatably connected to the output end of the motor 4.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
