Description

Technical Field

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

[0002] In the doping process of sodium-ion battery materials, the degree of homogenization of composite active materials directly affects the cycle stability and energy density of the battery. Currently, the industry commonly uses vertical planetary mixers or screw mixers (such as publication number CN217989026U), but in practical applications, the following technical defects have been found: the single-directional rotation of the stirring paddle in the sodium-ion battery material doping device in related technologies causes the material to form a laminar flow only in the horizontal plane, failing to overcome the axial mixing barrier. Experimental data shows that when processing solid-phase doping of Ni / Fe / Mn ternary precursors with Na2CO3, the axial composition difference of conventional equipment is as high as 12.7%, seriously affecting the bulk homogeneity of the material and resulting in low stirring efficiency. Especially when processing viscous or easily agglomerated materials, it is difficult to effectively break up clumps or agglomerates, limiting the quality and efficiency of doping. At the same time, the stirring mode of existing stirring devices is relatively fixed, lacking flexibility and making it difficult to adjust according to different material characteristics or doping process requirements, reducing the adaptability and efficiency of the production process. Therefore, it is necessary to improve the current sodium-ion battery material doping device to solve the above problems.

[0003] The information disclosed in this background section is only for understanding the background technology of the inventive concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0004] The purpose of this invention is to provide a device for producing sodium-ion battery materials doping, addressing the problem in the background art where the single-directional rotation of the stirring paddle in sodium-ion battery material doping devices results in laminar flow of materials only in the horizontal plane, failing to overcome the axial mixing barrier. Experimental data shows that when processing solid-phase doping of Ni / Fe / Mn ternary precursors with Na2CO3, conventional equipment exhibits an axial composition difference as high as 12.7%, severely affecting the bulk homogeneity of the material and resulting in low stirring efficiency. This is particularly problematic when processing viscous or easily agglomerated materials, as it is difficult to effectively break up clumps or agglomerates, limiting the quality and efficiency of doping. Furthermore, the existing stirring modes of these devices are relatively fixed, lacking flexibility and making it difficult to adjust according to different material characteristics or doping process requirements, thus reducing the adaptability and efficiency of the production process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for producing sodium-ion battery materials includes a fixed frame, a stirring chamber, and a discharge rack. A rotating shaft seat is symmetrically mounted on the upper end of the fixed frame. The inner side of the rotating shaft seat is connected to the stirring chamber. A drive shaft is installed inside the stirring chamber. Spiral stirring blades and fan-shaped stirring blades are mounted around the drive shaft on its outer side. A discharge port pipe is installed at the lower end of the stirring chamber. A first rotating plate and a second rotating plate are respectively installed on both sides of the discharge port pipe. Two ends of a second electric telescopic rod are respectively installed on one side of the first and second rotating plates. The upper ends of the first and second rotating plates are connected by a first gear and a second gear meshing together.

[0007] As a preferred technical solution, a first electric telescopic rod is installed on one side of the stirring chamber, the upper end of the first electric telescopic rod is connected to a cover plate, a clutch is connected to one side of the rotating shaft seat, and a servo motor is connected to one side of the clutch.

[0008] As a preferred technical solution, vibrators are symmetrically installed on both sides of the discharge port pipe.

[0009] As a preferred technical solution, a discharge rack is installed on one side of the fixed frame, and a discharge plate is fixedly installed on the upper end of the discharge rack. The discharge plate is located on one side of the mixing chamber.

[0010] As a preferred technical solution, a controller is fixedly installed on the upper end of the servo motor, and the controller is electrically connected to the servo motor, clutch, first electric telescopic rod, second electric telescopic rod, and vibrator.

[0011] The beneficial effects of this utility model are:

[0012] In this device, the drive shaft is installed inside the mixing chamber and arranged longitudinally. Spiral and fan-shaped stirring blades are mounted around its outer side. A servo motor is connected to the drive shaft via a clutch, providing power. During operation, the servo motor is started, and the clutch engages, driving the drive shaft to rotate. The spiral stirring blades, through their spiral structure, propel the material in an axial circulation within the chamber, while the fan-shaped stirring blades break up clumps or agglomerates in the material, achieving multi-dimensional mixing. The clutch can independently control the rotation of the drive shaft or coordinate its movement with the mixing chamber as needed. The combination of the clutch and the servo motor provides flexible mixing mode selection, adapting to different material properties and doping requirements, thus improving the device's applicability and mixing efficiency.

[0021] Reference Figure 1-4 A device for producing sodium-ion battery materials includes a fixed frame 1, a stirring chamber 2 and a discharge rack 16. A rotating shaft seat 8 is symmetrically installed on the upper end of the fixed frame 1. The inner side of the rotating shaft seat 8 is connected to the stirring chamber 2. A first electric telescopic rod 7 is installed on one side of the stirring chamber 2. The upper end of the first electric telescopic rod 7 is connected to a cover plate 6.

[0022] Through this design, the symmetrically arranged rotating shaft seats 8 are connected to the stirring chamber 2, allowing the stirring chamber 2 to have a certain rotatable angle. The first electric telescopic rod 7 is installed on one side of the stirring chamber 2, and its upper end is connected to the cover plate 6. The cover plate 6 is opened or closed by the telescopic movement of the electric telescopic rod. During operation, the cover plate 6 is first opened by retracting the first electric telescopic rod 7, and the sodium-ion battery material to be doped and the dopant are added into the stirring chamber 2. Then, the first electric telescopic rod 7 is extended to close the cover plate 6, forming a closed stirring space. This facilitates material addition and sealing operations, prevents external impurities from entering, and improves the cleanliness and safety of the doping process.

[0023] The mixing chamber 2 is equipped with a drive shaft 5. Spiral stirring blades 501 and fan-shaped stirring blades 502 are installed around the outside of the drive shaft 5. One side of the rotating shaft seat 8 is connected to a clutch 4, and one side of the clutch 4 is connected to a servo motor 3.

[0024] In this design, the drive shaft 5 is installed inside the mixing chamber 2, arranged longitudinally. Spiral stirring blades 501 and fan-shaped stirring blades 502 are mounted around its outer side. The servo motor 3 is connected to the drive shaft 5 via a clutch 4, providing power. During operation, the servo motor 3 is started, and the clutch 4 engages, driving the drive shaft 5 to rotate. The spiral stirring blades 501, through their spiral structure, push the material to circulate axially within the chamber, while the fan-shaped stirring blades 502 break up clumps or agglomerates in the material with their fan-shaped surfaces, achieving multi-dimensional mixing. The clutch 4 can independently control the rotation of the drive shaft 5 or coordinate its movement with the mixing chamber 2 as needed. The cooperation between the clutch 4 and the servo motor 3 provides flexible mixing mode selection, adapting to different material properties and doping requirements, thus improving the applicability and mixing efficiency of the device.

[0025] Furthermore, a discharge port pipe 9 is installed at the lower end of the mixing chamber 2, and a first rotating plate 12 and a second rotating plate 15 are respectively installed on both sides of the discharge port pipe 9. The two ends of the second electric telescopic rod 10 are installed on one side of the first rotating plate 12 and the second rotating plate 15. The upper ends of the first rotating plate 12 and the second rotating plate 15 are connected by the meshing of the first gear 13 and the second gear 14. Vibrators 11 are symmetrically installed on both sides of the discharge port pipe 9.

[0026] With this design, the discharge port pipe 9 is installed at the lower end of the mixing chamber 2, serving as a discharge channel for the mixed waste. A first rotating plate 12 and a second rotating plate 15 are respectively located on both sides of the pipe. The two ends of a second electric telescopic rod 10 are connected to one side of the two rotating plates, driving the first rotating plate 12 and the second rotating plate 15 to rotate through telescopic movement. Since the upper ends of the two rotating plates are connected by a first gear 13 and a second gear 14, the movement of the second electric telescopic rod 10 allows the two rotating plates to open and close synchronously or adjust their angle. During operation, after mixing, the second electric telescopic rod 10 is controlled to extend and retract, driving the rotating plates to adjust the opening size of the discharge port pipe 9, guiding the waste to an external collection device. Furthermore, vibrators 11 are symmetrically installed on both sides of the discharge port pipe 9, generating high-frequency vibrations during waste discharge. These vibrations act on the pipe wall, loosening or smoothing out the waste adhering to or accumulated on the inner wall of the pipe, ultimately discharging it to the outside through the discharge port pipe 9. The auxiliary effect of vibration improves the smoothness and integrity of the discharge, reduces waste residue, and ensures the continuity and cleanliness of the production process.

[0027] In other embodiments, a discharge rack 16 is installed on one side of the fixing frame 1, and a discharge plate 17 is fixedly installed on the upper end of the discharge rack 16. The discharge plate 17 is disposed on one side of the mixing chamber 2.

[0028] With this design, after doping is completed, the servo motor 3 drives the stirring chamber 2 to turn towards the discharge plate 17 through the clutch 4 to complete the discharge, so that the material is connected with the subsequent production process, improving the continuity of the production process and production efficiency.

[0029] In other embodiments, a controller 18 is fixedly mounted on the upper end of the servo motor 3, and the controller 18 is electrically connected to the servo motor 3, the clutch 4, the first electric telescopic rod 7, the second electric telescopic rod 10, and the vibrator 11.

[0030] In this embodiment, the drive shaft 5 is installed inside the stirring chamber 2 and arranged longitudinally. Spiral stirring blades 501 and fan-shaped stirring blades 502 are mounted around its outer side. The servo motor 3 is connected to the drive shaft 5 via a clutch 4, providing power. During operation, the servo motor 3 is started, and the clutch 4 engages, driving the drive shaft 5 to rotate. The spiral stirring blades 501, through their spiral structure, push the material to circulate axially within the chamber. Simultaneously, the fan-shaped stirring blades 502 break up clumps or agglomerates in the material with their fan-shaped surfaces, achieving multi-dimensional mixing. The clutch 4 can independently control the rotation of the drive shaft 5 or coordinate its movement with the stirring chamber 2 as needed. The cooperation between the clutch 4 and the servo motor 3 provides flexible stirring mode selection, adapting to different material properties and doping requirements, thus improving the applicability and stirring efficiency of the device.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
