The top of the vessel body and the bottom of the vessel cover are fixedly connected by multiple bolts. The vessel body has a jacketed groove inside. The top of the vessel cover is fixedly connected to one end of the rotating assembly. The surfaces of the two connecting columns are respectively fixedly connected to the surfaces of the rotating assembly.

Description

Technical Field

[0001] This invention relates to the field of electrolyte production control technology, and in particular to a control device for electrolyte production. Background Technology

[0002] Electrolyte is one of the core functional materials of lithium-ion batteries, playing a crucial role in transporting lithium ions between the positive and negative electrodes. Its performance directly determines the battery's energy density, cycle life, and safety characteristics. It is usually composed of lithium salts such as lithium hexafluorophosphate, carbonate mixed organic solvents, and functional additives. It has extremely high requirements for anhydrous and oxygen-free conditions and temperature uniformity in the production environment.

[0003] In the electrolyte production process, stirring and temperature control are the core links to ensure product quality. The principle is to disrupt the laminar flow state of the electrolyte by stirring, enhance the heat exchange between the fluid in the reactor and the heat exchange surface, thereby eliminating temperature gradients and maintaining temperature stability in the production process. However, there is an inherent contradiction between the low viscosity characteristics of electrolyte and its sensitive thermal stability. If the stirring speed is too high, it is easy to cause the volatilization of organic solvents and the generation of bubbles, which will destroy the anhydrous and oxygen-free environment of the electrolyte and reduce the purity of the product. If the speed is too low, it will not be able to effectively break the thermal boundary layer, and significant temperature differences will easily form between the center and the edge, and between the top and the bottom of the reactor. This will lead to problems such as uneven dissolution of lithium salt and local degradation of additives, which will seriously affect the batch consistency of electrolyte.

[0004] Traditional electrolyte production control devices mostly use single-shaft stirring devices, which can only achieve single rotational motion. The electrolyte easily forms a stable laminar boundary layer in the reactor, resulting in low heat exchange efficiency and limited temperature control accuracy. Some dual-shaft stirring devices use a multi-motor driven counter-rotating structure, which improves mixing efficiency, but the arrangement of multiple power sources increases the equipment size. In addition, the increased number of sealing points at the shaft end leads to a decrease in the sealing reliability under nitrogen protection, making it easy to introduce moisture or oxygen to contaminate the electrolyte. A few stirring devices with telescopic functions rely on additional cylinders or linear motors to drive axial movement, which has the problems of asynchronous rotation and telescopic actions, redundant mechanical structure, and cannot optimize the motion trajectory for the low viscosity characteristics of the electrolyte, and still cannot completely eliminate temperature gradients.

[0005] Therefore, it is necessary to provide a new control device for electrolyte production to solve the above-mentioned technical problems. Summary of the Invention

[0016] Compared with related technologies, the control device for electrolyte production provided by the present invention has the following advantages:

[0017] 1. The motor drives the lead screw to rotate, which in turn drives the first bevel gear, the second bevel gear, and the third bevel gear to rotate synchronously. At the same time, the first bevel gear on the surface of the lead screw drives the second bevel gear to rotate, driving the rotating shaft and the telescopic rod to reciprocate within the bidirectional spiral groove of the fixed cylinder. This, in turn, drives the stirring blade to achieve compound stirring. This motion mode can completely break the laminar flow state of the electrolyte, enhance the heat exchange between the fluid in the vessel and the heat exchange surface, and effectively eliminate the temperature gradient between the center and the edge, and between the top and bottom of the vessel. At the same time, under the condition of low electrolyte temperature and high viscosity, the stirring blade automatically adjusts its angle through the force relief buffer of the slider and the spring, reducing stirring resistance and avoiding waste of heating power. When the electrolyte temperature rises and the viscosity decreases, the stirring blade naturally unfolds to increase the stirring area, allowing the electrolyte in the high-temperature area to spread rapidly, avoiding local overheating, and significantly improving the mixing uniformity and temperature stability of the electrolyte.

[0018] 2. The motor drives a threaded rod, which in turn moves the moving block and heating coil up and down along the jacketed groove, enabling stratified heating of the electrolyte at different locations inside the vessel. When the moving block comes into contact with the sensor on the top or bottom wall of the jacketed groove, the heating coil automatically stops working. Heating resumes after the moving block moves away from the sensor. During cooling, cold water enters the cooling pipe through the inlet pipe and exits through the outlet pipe to remove heat. The stratified heating design allows for precise temperature control of electrolyte at different levels, avoiding local overheating or underheating. The coordinated operation of the heating and cooling systems improves the temperature control response speed, enhances temperature control accuracy, and reduces overall energy consumption. At the same time, the sensor's limiting design prevents excessive movement of the heating coil, improving the operational stability and service life of the equipment.

[0019] 3. The dual synchronous drive of the motor for compound stirring and secondary stirring eliminates the need for an additional power source, simplifies the structural layout of the reactor lid, reduces the number of shaft end sealing points, effectively improves the sealing reliability of the internal environment, and prevents moisture or oxygen from entering the reactor body through the sealing gaps and contaminating the electrolyte. It is suitable for the stringent requirements of electrolyte production for anhydrous and oxygen-free environments. Attached Figure Description

The surface of the second bevel gear 402 is rotatably connected to the surface of the rotating component. One side of the second bevel gear 402 is fixedly connected to one end of the rotating shaft 403. The other end of the rotating shaft 403 is fixedly connected to one end of the telescopic rod 404.

The bevel gear 308 on the surface of rod 303 drives the bevel gear 402 to rotate, which in turn drives the rotating shaft 403 and the telescopic rod 404 to reciprocate within the bidirectional spiral groove 406 of the fixed cylinder 405. This, in turn, drives the stirring blade 410 to achieve compound stirring. This motion mode can completely break the laminar flow state of the electrolyte, enhance the heat exchange between the fluid in the vessel and the heat exchange surface, and effectively eliminate the temperature gradient between the center and the edge, and between the top and bottom of the vessel. At the same time, under the condition of low electrolyte temperature and high viscosity, the stirring blade 410 automatically adjusts its angle through the force relief buffer of the slider 4073 and the spring 4072 to reduce stirring resistance and avoid wasting heating power. When the electrolyte temperature rises and the viscosity decreases, the stirring blade 410 naturally unfolds to increase the stirring area, allowing the electrolyte in the high temperature area to spread rapidly, avoiding local overheating, and significantly improving the mixing uniformity and temperature stability of the electrolyte.

[0033] The rotating assembly includes a second motor 301, a connecting box 302, a lead screw 303, a first bevel gear 304, a second bevel gear 305, a driven mechanism, and two first bevel gears 308. One end of the second motor 301 is fixedly connected to the top of the vessel lid 3, and the output end of the second motor 301 is fixedly connected to the top of the lead screw 303.

The surface of the lead screw 303 is rotatably connected to the inner wall of the through hole opened at the top of the connecting box 302. The surface of the lead screw 303 is fixedly connected to the inner wall of the through hole opened on one side of the first bevel gear 304. The surfaces of the lead screw 303 are respectively fixedly connected to the inner walls of the through holes opened on one side of the two first bevel gears 308. Surface 303 is rotatably connected to the inner wall of the driven mechanism. The top of the connecting box 302 is fixedly connected to the bottom wall of the kettle cover 3. One side of the bevel gear 305 is rotatably connected to the inner wall of the connecting box 302. The bevel gear 305 meshes with the bevel gear 304. The bevel gear 305 is rotatably connected to the surface of the driven mechanism. The motor 301 synchronously drives the compound stirring and secondary stirring. No additional power source is required. This simplifies the structural layout of the kettle cover 3, reduces the number of shaft end sealing points, effectively improves the sealing reliability of the internal environment, and prevents moisture or oxygen from entering the kettle body 1 through the sealing gap and contaminating the electrolyte. This is suitable for the stringent requirements of electrolyte production for anhydrous and oxygen-free environments.

[0035] The jacketed groove 108 is equipped with an electric wire 102, a heating coil 103, a jacketing mechanism, a lifting mechanism, and two sensors 104. One end of the electric wire 102 is fixedly connected to the outer surface of the heating coil 103, and the surface of the electric wire 102 is fixedly connected to the inner wall of the through hole opened on the surface of the vessel body 1. The outer surface of the heating coil 103 is fixedly connected to one side of the lifting mechanism. The inner side of the jacketing mechanism is fixedly connected to the inner wall of the jacketed groove 108 of the vessel body 1.

[0036] The jacket mechanism includes a water inlet pipe 105, a cooling pipe 106, and a water outlet pipe 107. One end of the water inlet pipe 105 is fixedly connected to one end of the cooling pipe 106. The surface of the water inlet pipe 105 is fixedly connected to the inner wall of the through hole opened on the surface of the vessel body 1. The inner side of the cooling pipe 106 is fixedly connected to the inner wall of the jacket groove 108 of the vessel body 1. The end of the cooling pipe 106 away from the water inlet pipe 105 is fixedly connected to one end of the water outlet pipe 107. The surface of the water outlet pipe 107 is fixedly connected to the inner wall of the through hole opened on the surface of the vessel body 1. The outside of the water inlet pipe 105 is fixedly connected to a water pump. During cooling, the water pump continuously inputs cold water from the water inlet pipe 105 into the interior of the cooling pipe 106 to remove heat from the surface of the vessel body 1. The heated water is discharged into the drain tank through the water outlet pipe 107, realizing the rapid discharge of electrolyte heat and avoiding local overheating or insufficient heating.

[0037] The lifting mechanism includes a connecting frame 2, a motor 201, a threaded rod 202, and a moving block 203. The bottom of the connecting frame 2 is fixedly connected to the bottom wall of the jacket groove 108 of the vessel body 1, and the top of the connecting frame 2 is fixedly connected to the top wall of the jacket groove 108 of the vessel body 1. One end of the motor 201 is fixedly connected to the bottom wall of the connecting frame 2, and the output end of the motor 201 is fixedly connected to one end of the threaded rod 202. The other end of the threaded rod 202 is rotatably connected to the top wall of the connecting frame 2. The inner wall of the through hole on the surface of the moving block 203 is threadedly connected to the surface of the threaded rod 202. One side of the moving block 203 is fixed to the outer surface of the heating coil 103. The connection is achieved by driving the threaded rod 202 through the motor 201, which in turn drives the moving block 203 and the heating coil 103 to rise and fall along the jacket groove 108, thereby realizing the layered heating of the electrolyte at different positions inside the vessel body 1. When the moving block 203 abuts against the sensor 104 on the top or bottom wall of the jacket groove 108, the heating coil 103 automatically stops working and resumes heating after leaving the sensor 104. This improves the temperature control response speed, enhances the temperature control accuracy, and reduces the overall energy consumption. At the same time, the limiting design of the sensor 104 avoids excessive rising and falling of the heating coil 103, thereby improving the operational stability and service life of the equipment.

[0038] A controller 101 is fixedly connected to the surface of the vessel body 1, and a discharge pipe 109 is fixedly connected to the inner wall of the through hole at the bottom of the vessel body 1. A valve body for controlling the flow of liquid is fixedly connected inside the discharge pipe 109.

[0039] The working principle provided by this invention is as follows:

[0040] The start motor 201 drives the threaded rod 202 to rotate, causing the moving block 203 and heating coil 103 to rise and fall along the jacket groove 108, thus heating the electrolyte at different liquid levels in the vessel body 1 in layers. When the moving block 203 comes into contact with the sensor 104 on the top or bottom wall of the jacket groove 108, the heating coil 103 automatically cuts off the power and restores power after it moves away to achieve precise limit start and stop. During cooling, cold water enters the cooling pipe 106 through the water inlet pipe 105 and is discharged from the water outlet pipe 107, quickly removing the heat in the vessel to complete the hot and cold switching. At the same time, the start motor 301 drives the lead screw 303 to rotate, which on the one hand drives the bevel gear 304, bevel gear 305, and bevel gear 306 to rotate synchronously, thereby achieving secondary stirring through the rotating drum 307 and the connecting column 4. On the other hand, the bevel gear 308 on the surface of the lead screw 303 drives the bevel gear 308 to rotate. The bevel gear 402 drives the rotating shaft 403 and the telescopic rod 404 to reciprocate within the bidirectional spiral groove 406 of the fixed cylinder 405. This drives the fixed block 407, sliding block 408, limiting block 409, and stirring blade 410 to complete compound stirring. When the electrolyte temperature is low and the viscosity is high, the stirring blade 410 automatically adjusts to a small angle to reduce resistance through the force relief buffer of the slider 4073 and the spring 4072. When the temperature rises and the viscosity decreases, it naturally expands to increase the stirring area to avoid local overheating. The entire system synchronously drives the dual stirring units through a single motor 301, which simplifies the structure of the vessel lid 3 and reduces the number of sealing points, improving the sealing reliability in the internal environment. The deep coordination of temperature control and stirring enhances the heat exchange efficiency, ultimately ensuring the mixing uniformity, temperature stability, and batch consistency of the electrolyte.
