Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a stirring device for electrolyte solvent that is easy to clean, including a solvent stirring tank 1 and an electrolyte stirring and cleaning device. A feed pipe 2 is fixedly connected to the top of the solvent stirring tank 1, and a sealing plug 3 is installed at the top of the feed pipe 2. A discharge pipe 4 is fixedly connected to the surface of the solvent stirring tank 1. The electrolyte stirring and cleaning device includes three support frames 5, a servo motor 6, a rotating shaft 7, four stirring shafts 8, and four spiral blades 9. The three support frames 5 are fixedly connected to the bottom of the solvent stirring tank 1 at equal intervals in a circular shape. The servo motor 6 is fixedly installed inside the three support frames 5. The rotating shaft 7 is rotatably installed inside the solvent stirring tank 1, and the lower end of the rotating shaft 7 is fixedly connected to the output end of the servo motor 6. The four stirring shafts 8 are fixedly connected to the surface of the rotating shaft 7 at equal intervals linearly. The four spiral blades 9 are respectively fixedly connected to the surfaces of the four stirring shafts 8, and all four spiral blades 9 are in contact with the inner wall of the solvent stirring tank 1.

[0025] After the staff removes the sealing plug 3, the staff can add the electrolyte raw materials into the inside of the solvent stirring tank 1 through the feed pipe 2. Then, after starting the servo motor 6, the output end of the servo motor 6 rotates and first drives the rotating shaft 7 to rotate. The rotation of the rotating shaft 7 can drive the four stirring shafts 8 to rotate simultaneously. The rotation of the four stirring shafts 8 can drive the four spiral blades 9 to rotate simultaneously to stir the raw materials inside the solvent stirring tank 1. Since the spiral blades 9 are of a spiral structure, the raw materials adhered to the inner wall of the solvent stirring tank 1 can be scraped off during the rotation of the spiral blades 9, preventing the raw materials of the electrolyte solvent from adhering to the inner wall of the solvent stirring tank 1, maintaining the cleanliness of the inner wall of the solvent stirring tank 1, not only improving the uniformity of the mixing of the electrolyte solvent, but also facilitating the staff to clean the inner wall of the solvent stirring tank 1.

[0026] An automatic feeding pipe 10 is fixedly connected to the top of the solvent stirring tank 1, and a conical feeding funnel 11 is fixedly connected to the top of the automatic feeding pipe 10. A rotating rod 14 is rotatably connected to the inside of the solvent stirring tank 1. A rotating wheel 15 is fixedly connected to the right end of the rotating rod 14. A threaded rod 13 is fixedly connected to the left end of the rotating rod 14. A regulating plate 12 is threadedly connected to the surface of the threaded rod 13, and the top of the regulating plate 12 is in contact with the top wall of the solvent stirring tank 1. Six dispersing rods 16 are fixedly connected to the upper end of the rotating shaft 7 at equal intervals in a circular shape.

[0027] After the staff pour the additive raw materials into the interior of the conical feed funnel 11, then, by rotating the rotating wheel 15 to rotate the rotating rod 14, the rotation of the rotating rod 14 can drive the threaded rod 13 to rotate inside the adjusting plate 12. Since the top of the adjusting plate 12 is in contact with the top wall of the solvent stirring tank 1, the adjusting plate 12 will not rotate along with the threaded rod 13. The rotation of the threaded rod 13 can drive the adjusting plate 12 to gradually slide to the right. By sliding the adjusting plate 12 to adjust the overlapping area with the lower end of the automatic feeding pipe 10, the opening size of the lower end of the automatic feeding pipe 10 can be adjusted. At this time, the staff can make the additive in the conical feed funnel 11 fall automatically into the interior of the solvent stirring tank 1 quantitatively. At this time, the rotation of the rotating shaft 7 can drive the dispersing rod 16 to rotate and disperse the falling additive, so as to make the additive uniformly diffuse inside the solvent stirring tank 1 and improve the uniformity of the mixture between the raw materials and the additive inside the solvent stirring tank 1.

[0028] Working principle: For this electrolyte solvent stirring device that is easy to clean, after the staff remove the sealing plug 3, the electrolyte raw materials can be added into the interior of the solvent stirring tank 1 through the feeding pipe 2. Then, after starting the servo motor 6, the output end of the servo motor 6 rotates to drive the rotating shaft 7 to rotate first. The rotation of the rotating shaft 7 can drive the four stirring shafts 8 to rotate simultaneously. The rotation of the four stirring shafts 8 can drive the four spiral blades 9 to rotate simultaneously to stir the raw materials inside the solvent stirring tank 1. During the rotation of the spiral blades 9, the raw materials adhered to the inner wall of the solvent stirring tank 1 can be scraped off to prevent the raw materials of the electrolyte solvent from adhering to the inner wall of the solvent stirring tank 1. After the staff pour the additive raw materials into the interior of the conical feed funnel 11, then, by rotating the rotating wheel 15 to rotate the rotating rod 14, the rotation of the rotating rod 14 can drive the threaded rod 13 to rotate inside the adjusting plate 12. The rotation of the threaded rod 13 can drive the adjusting plate 12 to gradually slide to the right. At this time, the staff can make the additive in the conical feed funnel 11 fall automatically into the interior of the solvent stirring tank 1 quantitatively. At this time, the rotation of the rotating shaft 7 can drive the dispersing rod 16 to rotate and disperse the falling additive, improving the uniformity of the mixture between the raw materials and the additive inside the solvent stirring tank 1.

[0029] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present invention.
