[0002] Electrolyte additives require solid-liquid separation during production or use, primarily to remove impurities, purify active ingredients, or recover valuable substances. Additives may contain unreacted raw materials, byproducts, or solid particles, which can affect electrolyte performance and battery stability. Solid-liquid separation (such as filtration, centrifugation, or sedimentation) ensures the purity and uniformity of the electrolyte, thereby improving the battery's electrochemical performance, cycle life, and safety. Furthermore, the separated solid residue may contain recyclable materials, reducing resource waste and meeting environmental protection requirements.

[0003] Existing solid-liquid separation technologies for electrolyte additives often face the following drawbacks: the filter cartridge replacement process of traditional equipment is cumbersome and time-consuming, requiring manual handling and alignment, increasing operational intensity and making it easy to come into contact with corrosive materials; the sealing structure lacks reliability; solvent vapor or droplets are easily released during high-speed centrifugation, posing safety and environmental risks; and a large amount of liquid residue remains at the bottom of the tank after solid-liquid separation, especially for viscous additives, affecting separation efficiency and the purity of solid products.

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4This utility model discloses a solid-liquid separation device for producing electrolyte additives, including a fixed base 2 11. A tank 10 is fixedly connected inside the fixed base 2 11. A bracket 1 is fixedly connected to the lower end of the fixed base 2 11. A fixed base 9 is fixedly connected to the three ends of the outer side of the tank 10. A connecting frame 8 is fixedly connected to the upper two ends of the fixed base 9. A motor 12 is fixedly connected to the connecting frame 8 on the left side. The bracket 1 can stably support the device, and the connecting frame 8 can stably support the entire sealing assembly. An annular sealing groove is designed on the lower end face of the sealing cover 6, and a corrosion-resistant and solvent-resistant sealing ring is installed.

[0027] The inner end of the connecting frame 8 on the left side has a slot 14. A lead screw 13 is rotatably connected inside the slot 14. A sealing cover 6 is threaded onto the lead screw 13. The output end of motor 12 is connected to the lead screw 13 via a coupling. A connecting shell 7 is fixedly connected to the upper end of the sealing cover 6. Motor 21 is fixedly connected to the inner left end of the connecting shell 7. Gear 1 20 is fixedly connected to the output end of motor 21. A rotating shaft 22 is rotatably connected to the inner right end of the connecting shell 7. A rotating plate 5 is fixedly connected downward through the sealing cover 6 at the bottom of the rotating shaft 22. Gear 23 is fixedly connected to the inner end of the connecting shell 7. Gear 1 20 and gear 23 are connected to each other. When motor 23 meshes with each other, motor 12 drives screw 13 to rotate. Under the action of the threaded engagement, the sealing cover 5 drives the filter cylinder 4 to gradually move into the tank 10. When it moves to the bottom, the sealing cover 5 can completely seal the upper opening of the tank 10. Then, motor 21 drives gear 20 to rotate. Under the meshing action, gear 23 and shaft 22 can rotate, thereby driving the internal rotating plate 5 and filter cylinder 4 to rotate. The rotation of filter cylinder 4 generates centrifugal force inside, thereby throwing out the liquid and discharging it through the drain port 3 at the bottom, thus completing the rapid solid-liquid separation of electrolyte additives.

[0028] A filter cartridge 4 is installed below the rotating plate 5. An installation block 15 is fixedly connected to the four ends of the outer side of the filter cartridge 4. Several through holes are opened on the filter cartridge 4, and a filter screen is installed inside the through holes. The liquid can be thrown out from the inside under centrifugal force. The filter cartridge 4 is made of highly corrosion-resistant 316L stainless steel. The filter screen is made of 316L stainless steel. The filter screen pore size is selected according to the size of the target solid particles.

[0029] The four outer ends of the rotating plate 5 are fixedly connected to the mounting block 2 17. The mounting block 2 17 and the internal thread of the mounting block 1 15 are fitted with positioning bolts 16, and the upper end of the positioning bolts 16 is fitted with nuts. By setting the mounting block 1 15, mounting block 2 17, positioning bolts 16 and nuts, it is convenient for the staff to disassemble the filter cartridge 4. At the same time, when disassembling, the entire automated structure can raise the filter cartridge 4 to the optimal height before disassembly, which improves the disassembly convenience of the device.

[0030] The connecting frame 8 on the right side has a sliding groove 19 inside, and a sliding rod 18 is fixedly connected inside the sliding groove 19. The sealing cover 6 is slidably connected to the sliding rod 18. By setting the sliding groove 19 and the sliding rod 18, the stability of the entire filter cartridge 4 when it is raised and lowered after installation can be improved.

[0031] The bottom of the tank 10 is provided with a drain port 3, and a solenoid valve 2 is installed inside the drain port 3. The drain port 3 allows the separated liquid to be discharged outwards. The solenoid valve 2 can control the opening and closing of the drain port 3. The bottom of the tank 10 is designed with an inclined bottom surface, with the lowest point located at the drain port 3, so that the separated liquid can be completely collected and discharged under the action of centrifugal force and gravity, reducing liquid residue. After the separation process is completed, keep the filter cartridge 4 rotating at a low speed (or pause briefly) before opening the solenoid valve 2 to drain the liquid. Use the remaining centrifugal force to help the liquid be completely discharged. Before starting the second motor 21 for centrifugal separation, it must be confirmed that the sealing cover 6 has been lowered into place and locked, the top cover of the tank 10 has been sealed, and the filter cartridge 4 has been firmly installed by the positioning bolts 16. During equipment operation, personnel should stay away from the rotating parts area. Before disassembling the filter cartridge 4, it must be ensured that the first motor 12 and the second motor 21 have been completely stopped and the equipment is in a safe power-off state.

[0032] Working principle: During use, the operator places the electrolyte additive to be separated inside the filter cartridge 4. Then, the mounting block 15 is aligned with the mounting block 17 on the rotating plate 5, and the filter cartridge 4 is locked under the rotating plate 5 using the positioning bolt 16. Next, the motor 12 is started to drive the lead screw 13 to rotate. Under the action of the threaded engagement, the sealing cover 5 drives the filter cartridge 4 to gradually move into the tank 10. When it moves to the bottom, the sealing cover 5 can completely seal the upper opening of the tank 10. Subsequently, the motor 21 is started to drive the gear 20 to rotate. Under the meshing action, the gear 23 and the rotating shaft 22 are rotated, thereby driving the internal rotating plate 5 and the filter cartridge 4 to rotate. The rotation of the filter cartridge 4 generates centrifugal force, thereby throwing out the liquid, which is discharged through the drain port 3 at the bottom. This completes the rapid solid-liquid separation of the electrolyte additive, improving the separation effect of the entire device. In subsequent cleaning, the entire sealing assembly is raised, and the filter cartridge 4 can be disassembled and replaced.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
