[0003] In the prior art, the dual planetary mixer used for producing and preparing battery slurry usually has three dispersion discs installed on the high-speed rotating shaft. In the later stage of slurry making, the blades on the dispersion discs are used to shear the materials to achieve the dispersion of the battery slurry and accelerate the output of the battery slurry. However, due to the small contact area between the dispersion disc and the material, the weak point of force, and the easy deformation under strong force, the dispersion disc cannot participate in the high-viscosity material mixing operation in the early stage of slurry making, resulting in a long mixing time in the early stage and low production efficiency of battery slurry. Utility Model Content

[0036] A planetary gearbox 2, which is installed on the support frame 1;

[0037] A stirring paddle 3, which is installed at the output end of the planetary gearbox 2 and is driven to rotate by the planetary gearbox 2;

[0038] A rotating shaft 4, which is installed at the output end of the planetary gearbox 2 and is driven to rotate by the planetary gearbox 2;

[0039] A dispersion disc 5, which is installed on the rotating shaft 4;

[0040] A kneading disc 6, which includes a disc body 8 and a plurality of kneading members 7. The disc body 8 is installed on the rotating shaft 4 and is located below the dispersion disc 5, and the kneading members 7 are installed on the disc body 8.

[0041] In this technical solution, the stirring paddle 3 and the rotating shaft 4 are both installed on the planetary gearbox 2, and the rotating shaft 4 and the stirring paddle 3 are arranged adjacent to each other. When performing the pulping operation, in the early steps of pulping, the planetary gearbox 2 drives the stirring paddle 3 and the rotating shaft 4 to revolve around the center of the planetary gearbox 2, and at the same time, the rotating shaft 4 rotates at a high speed by itself. The kneading disc 6 on the rotating shaft 4 rotates together with the rotation of the rotating shaft 4, and the kneading member 7 on the kneading disc 6 exerts a force on the high-viscosity material, kneading and patting the material at a high speed to accelerate the stirring and mixing of the material. It is worth mentioning that the kneading member 7 can be a pin or other high-strength objects as long as it can exert a large force on the material.

[0042] A dispersion disc 5 is also provided on the rotating shaft 4. The dispersion disc 5 is located above the kneading disc 6 and is set at a suitable position on the rotating shaft 4. After adding the solvent in the later stage of pulping, the dispersion disc 5 can contact the material. The dispersion disc 5 rotates together with the rotation of the rotating shaft 4, thereby achieving a dispersion effect on the solvent added to the material.

[0043] In summary, through this structural design, the high-speed rotation of the rotating shaft 4 can be started in the early stage of pulping. The kneading member 7 on the kneading disc 6 is used to effectively knead and pat the high-viscosity material, accelerating the uniform mixing of the material, improving the energy consumption ratio, and reducing resource waste; while in the later stage of pulping, the dispersion disc 5 can be used to disperse the material after adding the solvent, ensuring the dispersion efficiency in the later stage of pulping. The combination of the two can effectively shorten the entire preparation time of the battery slurry, thereby improving the production efficiency of the battery slurry.
