[0035] Reference below Figures 1 to 4 A device for configuring lithium battery electrolyte according to an embodiment of the utility model is described.

[0036] like Figure 1 and Figure 2 As shown, the lithium battery electrolyte configuration device according to the embodiment of the utility model includes a kettle body 100 , a cover body 200 , an inner container 300 and a stirring mechanism 400 .

[0037] Among them, the top end of the kettle body 100 is opened, the cover body 200 is detachably installed on the top end of the kettle body 100, the inner side wall of the cover body 200 is provided with a limiting portion 201, and the bottom end of the limiting portion 201 is provided with a recess 202. The top end of the liner 300 is opened and located in the inner cavity of the kettle body 100. The top end of the side wall of the liner 300 is inserted into the recess 202, and the bottom end of the liner 300 abuts against the bottom end of the inner cavity of the kettle body 100. The stirring mechanism 400 includes a stirring shaft 401 and a driving motor 402 installed on the cover body 200. The stirring shaft 401 can be rotatably installed on the cover body 200 around a vertical axis, the stirring shaft 401 extends into the liner 300, and the driving motor 402 is connected to the stirring shaft 401.

[0038] Place the inner liner 300 in the kettle body 100, then install the cover body 200 on the top of the kettle body 100, so that the top of the side wall of the inner liner 300 is inserted into the recess 202 of the limiter 201, and the installation of the inner liner 300 is completed. Add a variety of electrolyte raw materials into the inner liner 300, start the drive motor 402, and the drive motor 402 can drive the stirring shaft 401 to rotate, so that the stirring shaft 401 can mix the electrolyte raw materials in the inner liner 300, thereby realizing the configuration of the electrolyte. After long-term use, when the inner liner 300 is severely corroded and damaged, remove the cover body 200, take out the old inner liner 300, and replace it with a new inner liner 300.

[0039] Compared with the existing method of directly loading electrolyte raw materials through the kettle body 100, the lithium battery electrolyte configuration device according to the embodiment of the utility model loads electrolyte raw materials through the detachable inner liner 300, and the electrolyte raw materials will not corrode the kettle body 100. Even if the inner liner 300 is corroded, it is only necessary to replace the inner liner 300 instead of replacing the entire device, which is lower in cost.

[0040] It should be noted that there are many ways to detachably mount the cover 200 on the top of the kettle body 100, for example, Figure 1 As shown, a first mounting flange can be provided on the outer side wall of the top of the kettle body 100, and the first mounting flange extends along the circumference of the kettle body 100. A second mounting flange can be provided on the outer side wall of the bottom of the cover body 200, and the second mounting flange extends along the circumference of the cover body 200. A plurality of bolts can be installed between the first mounting flange and the second mounting flange. In addition, an external thread can be provided on the outer side wall of the top of the kettle body 100, and an internal thread can be provided on the inner side wall of the bottom of the cover body 200. The kettle body 100 and the cover body 200 are threadedly connected. It is only necessary that after the cover body 200 is installed on the kettle body 100, the top of the side wall of the inner tank 300 can be just inserted into the concave position 202 of the limiting portion 201. The part of the stirring shaft 401 in the inner tank 300 can be provided with stirring blades to better stir the electrode liquid raw material. Since the top of the side wall of the inner pot 300 is inserted into the recess 202 of the limiting portion 201 and the bottom abuts against the bottom of the inner cavity of the kettle body 100 , the inner pot 300 can be limited, thereby achieving installation of the inner pot 300 .

[0041] In some embodiments of the present invention, the limiting portion 201 is configured as an annular structure and extends along the circumference of the cover 200, and the concave portion 202 is correspondingly configured as an annular structure and extends along the circumference of the limiting portion 201. Such a configuration can further prevent the inner liner 300 from moving, so that the limiting portion 201 has a better limiting effect on the inner liner 300, thereby making the inner liner 300 more firmly installed.

[0042] In some embodiments of the present invention, Figure 1As shown, the outer wall of the inner liner 300 and the inner wall of the kettle body 100 enclose a cooling chamber 101, the limiting portion 201 blocks the top of the cooling chamber 101, and the kettle body 100 is provided with a water inlet pipe 102 and a water outlet pipe 103 connected to the cooling chamber 101. When the electrolyte raw materials are mixed, a chemical reaction will occur to generate a large amount of heat. If the temperature is too high, it will not only easily damage the inner liner 300 and the kettle body 100, but also cause a safety accident. In this embodiment, cooling water flows in from the water inlet pipe 102 and is discharged from the water outlet pipe 103. The cooling water flows through the cooling chamber 101, and then the inner liner 300 and the kettle body 100 can be cooled to prevent the inner liner 300 and the kettle body 100 from being too high. Moreover, since the cooling chamber 101 is enclosed between the outer wall of the inner liner 300 and the inner wall of the kettle body 100, the cooling effect of the cooling water on the inner liner 300 and the kettle body 100 is better. The limiting portion 201 blocks the top of the cooling cavity 101 , so that the cooling cavity 101 can form a sealed cavity to prevent the cooling water from overflowing from the top of the cooling cavity 101 .

[0043] In some embodiments of the present invention, Figure 2 As shown, a first sealing ring 203 is installed in the recess 202, and the top of the side wall of the inner liner 300 abuts against the first sealing ring 203. This arrangement makes the sealing between the inner liner 300 and the limiting portion 201 better, and prevents the cooling water in the cooling cavity 101 from flowing out from the gap between the inner liner 300 and the limiting portion 201.

[0044] In some embodiments of the present invention, Figure 1 As shown, the water inlet pipe 102 is arranged at the bottom end of one side of the kettle body 100, and the water outlet pipe 103 is arranged at the top end of the side of the kettle body 100 facing away from the water inlet pipe 102. After the cooling water flows into the cooling cavity 101 from the bottom end of one side of the kettle body 100, it needs to flow toward the other side of the cooling cavity 101 and flow upwards, so that it can be discharged from the top end of the other side of the cooling cavity 101 through the water outlet pipe 103, so that the cooling water flows through a wider area, thereby having a better cooling effect on the kettle body 100 and the inner tank 300.

[0045] In some embodiments of the present invention, Figure 3 As shown, the bottom end of the inner cavity of the kettle body 100 is provided with a plurality of support parts 104, and the top end of the support part 104 is provided with a limiting groove 105, and the bottom end of the inner liner 300 is correspondingly provided with an inserting part 301, which is inserted into the limiting groove 105 and abuts against the bottom surface of the limiting groove 105. By mutually inserting the support part 104 and the inserting part 301, the bottom end of the inner cavity can be supported and positioned, which not only makes the installation of the inner liner 300 more stable and prevents the inner liner 300 from moving at will, but also prevents the bottom surface of the inner liner 300 from directly contacting the kettle body 100 and damaging the inner liner 300.

[0046] It should be noted that in some other embodiments of the present invention, a plurality of support portions 104 may be provided at the bottom end of the inner cavity of the kettle body 100, a plug-in portion 301 may be correspondingly provided at the bottom end of the inner tank 300, a limiting groove 105 may be provided at the bottom end of the plug-in portion 301, and the support portion 104 may be inserted into the limiting groove 105 and abut against the top surface of the limiting groove 105.

[0047] In some embodiments of the present invention, Figure 4 As shown, a discharge pipe 302 is provided at the bottom end of the inner tank 300, and a clearance hole 106 is provided at the bottom end of the kettle body 100. The discharge pipe 302 is passed through the clearance hole 106, and the outer wall of the discharge pipe 302 fits the hole wall of the clearance hole 106. The discharge pipe 302 is provided to facilitate the discharge of the configured electrolyte, which is more convenient to use. The clearance hole 106 is provided, and when the inner tank 300 needs to be installed, the discharge pipe 302 can be passed through the clearance hole 106. When the inner tank 300 needs to be disassembled, the discharge pipe 302 can be pulled out from the top of the clearance hole 106, which is convenient for disassembly and assembly. The outer wall of the discharge pipe 302 fits the hole wall of the clearance hole 106, reducing the cooling water in the cooling chamber 101 from the outer wall of the discharge pipe 302 and the hole wall of the clearance hole 106.

[0048] In some embodiments of the present invention, Figure 4 As shown, the top of the clearance hole 106 is provided with an annular platform 107, and the outer wall of the discharge pipe 302 is provided with an annular flange 303 along the circumferential direction. The annular flange 303 is located in the annular platform 107, and the outer wall of the annular flange 303 is in contact with the inner wall of the annular platform 107. A second sealing ring 108 is provided between the bottom surface of the annular flange 303 and the bottom surface of the annular platform 107. When the discharge pipe 302 passes through the clearance hole 106, the annular flange 303 is located in the annular platform 107, and the outer wall of the annular flange 303 is in contact with the inner wall of the annular platform 107, and the bottom surface of the annular flange 303 abuts against the top surface of the second sealing ring 108, and the bottom surface of the annular platform 107 abuts against the bottom surface of the second sealing ring 108, so that the cooling water in the cooling cavity 101 can be further prevented from being discharged from the gap between the outer wall of the discharge pipe 302 and the hole wall of the clearance hole 106, and the sealing effect is better.

[0049] In some embodiments of the present invention, Figure 1 As shown, the cover 200 is provided with a plurality of feed pipes 204, and the bottom ends of the feed pipes 204 extend to the inner side of the limiting portion 201. Specifically, the top ends of the feed pipes 204 extend outside the cover 200 to facilitate feeding, and the bottom ends of the feed pipes 204 are located on the inner side of the limiting portion 201, and can be at the same height as the limiting portion 201, or slightly lower than the limiting portion 201. Such a configuration enables the electrolyte raw material to directly enter the inner liner 300, and prevents the electrolyte raw material from flowing onto the cover 200 and corroding the cover 200.

[0050] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
