Description

Technical Field

[0001] This application relates to the field of dry electrode preparation technology, and in particular to a mixing and homogenizing machine for dry electrodes. Background Technology

[0002] Dry electrode fabrication is a novel electrode preparation technology that avoids using liquid solvents to disperse active materials and conductive additives. Instead, it directly mixes powders of active materials, conductive agents, and binders together. In the dry electrode production process, the uniform mixing of the powders and the fiberization of the binder are crucial factors, directly affecting various properties of the electrode material, including conductivity, stability, and overall integrity.

[0003] In existing technologies, traditional single-axis stirring or simple biaxial stirring structures are generally used to mix powders. Because the stirring method of traditional stirring structures is singular, the stirring components only rotate and stir within a fixed plane, which easily leads to stratification of the powder during the mixing process. In particular, the high-concentration powder at the bottom of the container cannot be effectively sheared in the vertical direction, and tends to agglomerate, resulting in poor overall mixing and poor performance consistency of the electrode materials.

[0004] Therefore, there is a need for a stirring device that can improve the mixing effect of dry electrode powder. Utility Model Content

[0005] Based on this, the present invention provides a mixing and homogenizing integrated machine for dry electrode, the specific technical solution of which is as follows.

[0006] A dry electrode mixing and homogenizing integrated machine, comprising:

[0007] Mixing tank;

[0008] The first stirring assembly includes a first stirring motor, an outer stirring shaft, and stirring blades; the first stirring motor is drivenly connected to the outer stirring shaft; the outer stirring shaft is hollow and extends into the stirring tank; the stirring blades are connected to the outside of the outer stirring shaft.

[0009] The second stirring assembly includes a second stirring motor, an inner stirring shaft, a sleeve, and a dispersing disc. The second stirring motor includes a drive shaft. The inner stirring shaft passes through and is movably connected to the outer stirring shaft. One end of the inner stirring shaft has a drive groove, and the other end is connected to the dispersing disc. The drive shaft is inserted into the drive groove and is connected to the inner stirring shaft, enabling the inner stirring shaft to move relative to the drive shaft along the axial direction. The sleeve is connected to the stirring tank, and the inner wall of the sleeve has a guide groove that is connected end to end. The extension trajectories of the guide grooves are not on the same plane. The inner stirring shaft is rotatably inserted into the sleeve, and a limiting bolt is provided on the inner stirring shaft. The limiting bolt is movably inserted into the guide groove, so that when the second motor drives the inner stirring shaft to rotate, the limiting bolt moves along the extension trajectory of the guide groove, thereby driving the inner stirring shaft to reciprocate along the axial direction.

[0010] Furthermore, the stirring blade includes multiple sets of dispersing paddle assemblies arranged along the axial direction of the stirring outer shaft; the dispersing paddle assembly includes multiple dispersing paddles connected to the stirring outer shaft and arranged circumferentially.

[0011] Furthermore, the stirring blade also includes a rectangular frame connected to the outer stirring shaft, and scrapers are connected to the sides of the rectangular frame; there are multiple scrapers, and the multiple scrapers are inclined in the same direction.

[0012] Furthermore, the stirring blade also includes two spiral bands connected to the rectangular frame respectively. The spiral bands are spiral in shape, and the projections of the two spiral bands are located on the two diagonals of the rectangular frame respectively.

[0013] Furthermore, the dispersion disc includes a disc body and helical teeth; the disc body is connected to the stirring inner shaft, and multiple helical teeth are arranged around the outer contour of the disc body.

[0014] Furthermore, a first gear is connected to the outer shaft of the stirring unit, and a second gear is connected to the first stirring motor, with the first gear meshing with the second gear.

[0015] Furthermore, a third stirring assembly is provided at the bottom of the mixing tank; the third stirring assembly includes a third stirring motor and a grinding blade; the third stirring assembly is connected to the grinding blade in a driving connection, and the grinding blade is located below the dispersing disc.

[0016] Furthermore, the mixing tank includes a sealing cover and a tank body; the sealing cover is detachably connected to the tank body; the sealing cover is connected to a lifting assembly, which is used to drive the sealing cover to move vertically to separate from or close the tank body.

[0017] Furthermore, the sealing cap is provided with a feed inlet and a pressure relief valve, and the feed inlet is provided with an air inlet valve; the bottom of the tank is provided with a discharge outlet.

[0018] Furthermore, the tank body has an inner layer within its wall, and a temperature control component is installed within the inner layer.

[0019] Beneficial effects: The dry electrode mixing and homogenizing integrated machine provided by this utility model improves the mixing effect of solid powder of dry electrode by rotating the stirring blades on the outer stirring shaft and the stirring disc on the inner stirring shaft respectively. During the rotation of the inner stirring shaft, the inner stirring shaft can move back and forth along its axial direction under the cooperation of the limiting bolt and the guide groove. This allows the dispersion disc near the bottom of the tank to move up and down while rotating, which can dynamically shear powder of different heights and avoid stratification. Furthermore, the three-dimensional turbulence formed by the combined rotation and lifting motion can effectively improve the mixing uniformity and efficiency. Attached Figure Description

[0037] Example

[0038] This embodiment provides a mixing and homogenizing machine for dry electrode fabrication, referencing... Figure 1 and Figure 2 As shown, it includes a mixing tank, a first mixing component, and a second mixing component.

[0039] The first stirring assembly includes a first stirring motor 15, an outer stirring shaft 10, and stirring blades. The first stirring motor 15 is drivenly connected to the outer stirring shaft 10; the outer stirring shaft 10 is hollow and extends into the mixing tank. The stirring blades are connected to the outside of the outer stirring shaft 10. Powder is placed in the mixing tank, and the stirring blades are driven to rotate by the first stirring motor 15 to mix the powder.

[0040] The second stirring assembly includes a second stirring motor 12, an inner stirring shaft 9, a sleeve 903, and a dispersing disc 11. (Refer to...) Figure 6 and Figure 7As shown, the second stirring motor 12 includes a drive shaft 902; the inner stirring shaft 9 passes through the outer stirring shaft 10 and is movably connected to the outer stirring shaft 10, allowing the inner stirring shaft 9 and the outer stirring shaft 10 to rotate relative to each other and move relative to each other in the vertical direction. One end of the inner stirring shaft 9 is provided with a drive groove 901, and the other end is connected to a dispersion disk 11, so that the dispersion disk 11 is close to the bottom of the stirring tank. The drive shaft 902 is inserted into the drive groove 901 and is connected to the inner stirring shaft 9, allowing the inner stirring shaft 9 to move relative to the drive shaft 902 along the axial direction. Specifically, the drive shaft 902 and the drive groove 901 can be set as a mutually cooperating rectangular structure, thereby realizing the transmission and relative movement of the drive shaft 902 and the inner stirring shaft 9. The sleeve 903 is connected to the stirring tank, and the inner wall of the sleeve 903 is provided with a guide groove 904 connected end to end. The extension trajectory of the guide groove 904 is not on the same plane, that is, the trajectory of the guide groove 904 is a state of end to end connected from high to low and then back to high. The stirring inner shaft 9 is rotatably inserted into the sleeve 903, and a limiting bolt 905 is provided on the stirring inner shaft 9. The limiting bolt 905 is movably inserted into the guide groove 904, so that when the second motor drives the stirring inner shaft 9 to rotate, the limiting bolt 905 moves along the extension trajectory of the guide groove 904, thereby driving the stirring inner shaft 9 to reciprocate along the axial direction. When the second motor drives the stirring inner shaft 9 to rotate, the sleeve 903 remains fixed, so that the limiting bolt 905 will move along the trajectory of the guide groove 904, thereby driving the stirring inner shaft 9 to reciprocate along the axial direction. At the same time, the stirring inner shaft 9 also rotates, so that the dispersing disk 11 can rotate and move up and down at the same time, dynamically shearing the powder at different height levels, such as active substances, binders, and conductive agents in electrode slurry, reducing the "lighter at the top and heavier at the bottom" stratification problem caused by the density difference of the powder.

[0041] The dry electrode mixing and homogenizing integrated machine provided in this embodiment improves the mixing effect of dry electrode solid powder by rotating the stirring blades on the outer stirring shaft 10 and the stirring disc on the inner stirring shaft 9. During the rotation of the inner stirring shaft 9, the inner stirring shaft 9 can reciprocate along its axial direction under the cooperation of the limiting bolt 905 and the guide groove 904, so that the dispersing disc 11 near the bottom of the tank 1 can move up and down while rotating, which can dynamically shear powder of different heights, avoid stratification, and form a three-dimensional turbulence through the combined motion of rotation and lifting, which can effectively improve the mixing uniformity and efficiency.

[0042] Specifically, refer to Figure 5 As shown, the stirring blade includes multiple sets of dispersing paddle assemblies, scraper 19 and two spiral belts 18.

[0043] Multiple sets of dispersion paddle assemblies are arranged along the axial direction of the stirring outer shaft 10. Each dispersion assembly includes multiple dispersion blades 17 connected to the stirring outer shaft 10 and arranged circumferentially. All dispersion paddles are inclined in the same direction, so that the rotation of the stirring outer shaft 10 drives the dispersion blades 17 to move, pushing the powder to one side, changing the powder's trajectory, and causing the powder to collide and rub against each other during the movement. Through the mechanical action between the powders, dispersion and mixing are achieved. At the same time, the multi-angle powder movement further enhances the mixing effect.

[0044] The scraper 19 is connected to the outer stirring shaft 10 via a rectangular frame 16. Specifically, the rectangular frame 16 is connected to the outer stirring shaft 10, and the scraper 19 is connected to the side of the rectangular frame 16. There are multiple scrapers 19, and the multiple scrapers 19 are inclined in the same direction, so that the edges of the scrapers 19 are in contact with the inner wall of the mixing tank, preventing powder adhesion and promoting boundary layer mixing.

[0045] The spiral bands 18 are spiral-shaped, with two spiral bands 18 located on opposite sides of the rectangular frame 16, and the projections of the two spiral bands 18 lying on opposite diagonals of the rectangular frame 16. During rotation, they drive the powder to move in different directions; one group lifts the powder upwards, while the other pushes it downwards. Simultaneously, this, combined with lateral diffusion, creates a mixed motion of vertical circulation and lateral diffusion within the container 1, breaking up localized powder aggregation and enhancing mixing uniformity.

[0046] Specifically, the dispersing disc 11 includes a disc body and oblique teeth; the disc body is connected to the stirring inner shaft 9, and multiple oblique teeth are arranged around the outer contour of the disc body. Oblique teeth are arranged oppositely on the upper and lower sides of the disc body. During the stirring process, the disc body rotates and moves up and down, and the oblique teeth on its upper and lower circumferential edges agitate the powder, causing the powder to vortex and descend in a spiral shape. The oblique teeth shear the powder during its descent, achieving dispersion and refinement of the powder through mechanical force, thereby improving the uniformity and quality of the powder mixture.

[0047] Specifically, a first gear 13 is connected to the outer stirring shaft 10, and a second gear 14 is connected to the first stirring motor 15, with the first gear 13 meshing with the second gear 14.

[0048] Continue to refer to Figure 2As shown, a third stirring assembly is provided at the bottom of the mixing tank; the third stirring assembly includes a third stirring motor 26 and a grinding blade 25; the third stirring assembly is drivenly connected to the grinding blade 25, which is located below the dispersing disk 11. The grinding blade 25 is composed of three sets of overlapping and intersecting arc-shaped blades. During stirring, the grinding blade 25 rotates in the opposite direction to the dispersing disk 11, and the powder is repeatedly pulled and cut under the force in the opposite direction. At the same time, the arc-shaped structure of the blades enhances the ability to capture and break up particles. This design not only reduces powder deposition at the bottom but also improves mixing efficiency through vertical circulation convection, which is especially suitable for the high viscosity characteristics of dry electrode materials. It achieves synergistic optimization of mechanical shearing and spatial mixing, significantly shortens the process cycle, and improves material homogeneity.

[0049] Specifically, the mixing tank includes a sealing cover 4 and a tank body 1; the sealing cover 4 is detachably connected to the tank body 1; the sealing cover 4 is connected to a lifting assembly, which is used to drive the sealing cover 4 to move vertically to separate from or close with the tank body 1. The lifting assembly includes a hydraulic rod 21 and a lifting arm 22, the hydraulic rod 21 being connected to the lifting arm 22, and the lifting arm 22 being connected to the sealing cover 4. Both the first and second mixing assemblies are mounted on the sealing cover 4. By driving the sealing cover 4 to separate from the tank body 1, the first and second mixing assemblies can be moved outwards, facilitating the addition of powder and cleaning of the equipment.

[0050] Specifically, refer to Figure 5 As shown, a retaining ring plate 20 is detachably installed at the lower end of the sealing cover 4. The first gear 13 and the second gear 14 are respectively located in the interlayer between the retaining ring plate 20 and the sealing cover 4. The sleeve 903 is also located in the interlayer and connected to the sealing cover 4, which effectively prevents powder from entering the transmission mechanism and improves the reliability of equipment operation.

[0051] Specifically, the first stirring motor 15 and the second stirring motor 12 are both mounted on the sealing cover 4, and the stirring outer shaft 10 is rotatably mounted on the retaining ring plate 20. Specifically, it can be connected to the retaining ring plate 20 by bearings or other devices, and the stirring outer shaft 10 is positioned by the retaining ring plate 20.

[0052] Specifically, refer to Figure 8 As shown, the sealing cap 4 is equipped with a feed inlet 5 and a pressure relief valve 24. Powder can be added through the feed inlet 5, and an air inlet valve 23 is provided on the feed inlet 5. The air inlet valve 23 can be connected to an external nitrogen storage device to continuously introduce nitrogen into the mixing tank, forming an inert atmosphere and effectively preventing the dry electrode material from reacting chemically with oxygen during the high-speed stirring and friction heating process. The pressure relief valve 24 can balance the gas pressure in the mixing tank to ensure safe operation. The tank body 1 is installed on the base 3, so that the bottom of the tank body 1 is suspended. A discharge port 6 is provided at the bottom of the tank body 1 for easy removal of the mixed powder.

[0053] Specifically, the tank body 1 has a sandwich layer inside its wall, and a temperature control component is installed within this sandwich layer. This temperature control component can control the temperature inside the tank body 1 to meet the temperature control requirements of different process stages. Specifically, refer to... Figure 2 As shown, the temperature control component includes a cooling layer 7 and a heating layer 8. The cooling layer 7 adopts a spiral cooling pipe structure, and the cooling pipe is spirally coiled along the inner wall of the tank body 1. The heating layer 8 adopts a resistance wire heating structure, and the resistance wire is evenly distributed in the tank body 1.

[0054] Specifically, it also includes a control console 2, which controls the operation of each stirring component, the lifting and lowering of the sealing cover 4, and the temperature control component to adjust the temperature.

[0055] Work process:

[0056] 1. Low-speed premixing stage: Open the air inlet valve 23 and pressure relief valve 24 to introduce nitrogen into the tank 1 and remove air, creating an inert environment. Activate the cooling layer 7 to maintain the low-temperature environment inside the tank 1, preventing the binder from agglomerating due to frictional heating. Add the active electrode material, conductive agent, and binder through the feed inlet 5. Adjust the third stirring motor 26 to low-speed mode, causing the grinding blade 25 to rotate at low speed; adjust the first stirring motor 15 to low-speed mode, causing the outer stirring shaft 10 to rotate at low speed. The dispersion paddle pushes the powder to form a circumferential flow, while the spiral belt 18 on the rectangular frame 16 achieves up-and-down circulation of the powder, preventing accumulation; the scraper 19 adheres closely to the tank wall, ensuring that the boundary layer powder fully participates in the mixing. At this time, the inner stirring shaft 9 achieves initial dispersion of the powder with low shear force. During this process, the powder temperature is maintained at 5-20 degrees Celsius, initially completing the uniform mixing of the powder.

[0057] 2. High-speed mixing stage: After premixing, according to process requirements, the heating layer 8 is turned on, and the cooling layer 7 is adjusted to control the powder temperature between 30-100 degrees Celsius. The third stirring motor 26 is adjusted to high-speed mode, causing the grinding blade 25 to rotate at high speed; at the same time, the second stirring motor 12 is started and adjusted to high-speed mode, driving the dispersing disk 11 to rotate at high speed and move up and down. When descending, it strongly shears the powder at the bottom of the tank, breaking up agglomerated particles; when rising, it drives the upper layer of powder to impact downwards, forming convection with the spiral band 18 of the stirring outer shaft 10. The combined rotation and lifting motion creates a three-dimensional turbulent field inside the tank, which helps to mix the powder evenly. More importantly, the grinding blade 25 and the dispersing disk 11 rotate in opposite directions, forming a bidirectional shearing action on the powder between them, which can promote the fiberization process of the binder.

[0058] 3. End of Mixing and Equipment Maintenance: After the predetermined mixing time and effect are achieved, stop all stirring components and turn off the heating layer 8. Once the powder has cooled to the set temperature, open the sealing cover 4, and the mixed electrode powder material will be discharged from the outlet 6.

[0059] 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.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
