Description

Technical Field

[0001] The utility model relates to the technical field of electrolyte additive production, and particularly relates to an adding device for electrolyte additive production. Background Art

[0002] An electrolyte additive refers to a small amount of additive added to the electrolyte to improve the electrochemical performance of the electrolyte and enhance the quality of cathode deposition. The electrolyte additive is some natural or synthetic organic or inorganic compounds, which generally do not participate in the electrode reaction during the electrolysis process, but can improve the electrochemical performance of the electrolyte system, affect the discharge conditions of ions, and make the electrolysis process in a better state.

[0003] The currently disclosed patent: CN220459945U discloses a crystallization device for electrolyte additive production. By setting a rotating shaft, a first rotating rod, a turntable, a conveyor belt, a second rotating rod, fan blades and heating wires, it is convenient to stir and mix the solution, and then dry it simultaneously on both the left and right sides, facilitating the rapid drying of the electrolyte additive after crystallization, reducing the workload of staff transfer and reducing the use cost.

[0004] Based on the above search, the following problems exist in the use of the above patent: When the crystallization device for electrolyte additive production is in production, first, lithium difluorotetrahalophosphate is added to dry ethyl methyl carbonate and stirred. After the mixing and stirring are completed, heating and evaporation are carried out to obtain a solid. The addition method of lithium difluorotetrahalophosphate is to directly pour it into the interior of the crystallization device at one time, and make lithium difluorotetrahalophosphate stir and mix with ethyl methyl carbonate. A large amount of lithium difluorotetrahalophosphate is directly poured into the interior of the crystallization device, which is likely to cause the accumulation of lithium difluorotetrahalophosphate inside the crystallization device, being unfavorable for the uniform mixing of lithium difluorotetrahalophosphate and ethyl methyl carbonate, and thus affecting the mixing uniformity of lithium difluorotetrahalophosphate and ethyl methyl carbonate.

[0024] Please refer to Figures 1-4, the utility model provides a technical solution: an adding device for the production of electrolyte additives, including a treatment tank 1 and a material automatic adding device. A discharge port 2 is arranged on the surface of the treatment tank 1, a sealing plate 3 is installed inside the discharge port 2, a driving motor 4 is fixedly installed on the top of the treatment tank 1, a stirring shaft 5 is rotatably installed inside the treatment tank 1, the upper end of the stirring shaft 5 is fixedly connected to the output end of the driving motor 4, stirring blades 6 are fixedly connected to the surface of the stirring shaft 5, and a conical feeding pipe 7 is fixedly connected to the top of the treatment tank 1.

[0025] The staff can add dry ethyl methyl carbonate into the treatment tank 1 through the conical feeding pipe 7. After the staff starts the driving motor 4, the output end of the driving motor 4 rotates and first drives the stirring shaft 5 to rotate. The rotation of the stirring shaft 5 can drive the stirring blades 6 to rotate and stir the dry ethyl methyl carbonate raw material and other raw materials evenly.

[0026] The material automatic adding device includes an automatic adding pipe 8, three connecting rods 9, a conical spreading plate 10, a threaded rod 11, a circular turntable 12, a cylindrical adjusting block 13 and a guiding inclined pipe 14. The automatic adding pipe 8 is fixedly connected to the top of the treatment tank 1, the three connecting rods 9 are all fixedly connected to the bottom of the automatic adding pipe 8, the conical spreading plate 10 is fixedly connected to the lower ends of the three connecting rods 9, the threaded rod 11 is threadedly connected inside the automatic adding pipe 8, the circular turntable 12 is fixedly connected to the upper end of the threaded rod 11, the cylindrical adjusting block 13 is slidably connected inside the automatic adding pipe 8, the upper end of the cylindrical adjusting block 13 is rotatably connected to the lower end of the threaded rod 11, and the guiding inclined pipe 14 is fixedly connected to the surface of the automatic adding pipe 8.

After the staff pours the lithium bis(fluorotetrachloro)phosphate into the interior of the storage tank 16, the lithium bis(fluorotetrachloro)phosphate can flow into the interior of the automatic addition pipe 8 through the material guiding inclined pipe 14, and fall onto the surface of the conical spreading plate 10 under its own gravity, and the lithium bis(fluorotetrachloro)phosphate is spread and dropped through the conical spreading plate 10. The staff rotates the threaded rod 11 through the circular turntable 12. When the threaded rod 11 rotates, it can drive the cylindrical adjusting block 13 to slide up and down through the threaded connection with the automatic addition pipe 8 to adjust the opening size of the lower end of the material guiding inclined pipe 14, thereby adjusting the feeding speed of the lithium bis(fluorotetrachloro)phosphate. The lithium bis(fluorotetrachloro)phosphate can be slowly poured into the interior of the treatment tank 1 to improve the uniformity of the mixing of the lithium bis(fluorotetrachloro)phosphate and the ethyl methyl carbonate.
