Technical Field

[0001] The present invention relates to the technical field of electrolyte production and processing, and in particular to an electrolyte mixing device for battery manufacturing. Background Art

[0002] Electrolyte is a key component of electrochemical systems and comes in many different types. Its function is to achieve the conversion of electrical energy into chemical energy through ion transport. During the production and processing of electrolyte, different raw material components need to be evenly mixed together through a mixing device;

[0003] The patent document with the publication number "CN220003795U" discloses an "electrolyte mixing device, including an electrolyte tank body and a diversion box. The electrolyte tank body is a box structure with an open top. Disassembly and assembly components are installed on the top of both sides of the electrolyte tank body, and vertical plates are fixed to the bottom surfaces of the disassembly and assembly components on both sides. The utility model is provided with a diversion box that is detachably fixed on the lower part of the electrolyte tank body by means of vertical sliding cooperation between the matching seat and the matching groove and horizontal sliding cooperation between the limiting rod and the limiting hole. In this way, the electrolyte in the electrolyte tank body can be churned and mixed by means of air by ventilating the diversion box and discharging it through the evenly distributed air outlets. The diversion box The arrangement method in the electrolyte tank body is simple and easy to implement, replacing the stirring method of the rotating stirring paddle. The mixing range is not easily restricted and is conducive to improving the mixing efficiency of the electrolyte. Although the stirring method of the rotating stirring paddle is replaced, the mixing range is not easily restricted and is conducive to improving the mixing efficiency of the electrolyte. However, in the actual preparation process of the electrolyte, different electrolytes correspond to different reaction systems, and different reaction systems have different viscosities. When the viscosity of the reaction system is large, aeration alone cannot meet the mixing requirements. In addition, the open mixing environment makes the reaction system easily affected by oxygen and moisture in the ambient air, causing side reactions and reducing the quality of the electrolyte.

[0049] The stirring and mixing mechanism 6 includes a stirring component 61 and several mixing components 62. The stirring component 61 includes a servo motor 6101. The end of the output shaft of the servo motor 6101 is connected to a gear box 6102. One side of the gear box 6102 is connected to a stirring shaft 6103.

The outer ring of the sleeve shaft 6201 is fixedly installed with parallel blades 6203 outside the propeller blade 6202. The sleeve shaft 6201 is fixedly connected to the stirring shaft 6103 by bolts. The spiral directions of the propeller blades 6202 in two adjacent mixing components 62 are opposite. The servo motor 6101 is fixedly installed on the middle layer of the multi-stage base 4.

[0050] Specifically, during the electrolyte mixing process, the solvent is added to the mixing box 1, and the excess moisture in the solvent is absorbed by the molecular sieve in the drying carrying component 10. The air remaining in the mixing box 1 is evacuated by the vacuum recovery component 7 to prevent the oxygen and moisture in the residual air from affecting the mixing of the solvent and the solute. Then, the mixing box 1 is filled with inert protective gas through the aeration protection component 5, and the solvent and other additives are added to the mixing box 1. After the servo motor 6101 is started, it cooperates with the gear box 6102 to drive the stirring shaft 6103 to rotate, thereby driving the stirring paddle 6104 and the sleeve shaft 62 01 rotates synchronously, thereby driving the propeller blades 6202 and the parallel blades 6203 to rotate, thereby driving the solvent and solute to be stirred, and during the stirring process, the electrolyte is radially transported through the propeller blades 6202, so that the solvent and solute are mixed more evenly, and in the process of mixing the solvent and solute, the aeration protection component 5 continuously introduces inert protective gas into the mixing box 1, while protecting the reaction system, the auxiliary stirring and mixing mechanism 6 mixes the solvent and solute, and the gas in the mixing box 1 is extracted through the vacuum recovery component 7 to maintain the air pressure inside the mixing box 1 stable.

[0051] The gear box 6102 is a planetary gear reduction box with a reduction ratio range of 5:1 to 15:1. The outer shell of the gear box 6102 is connected to the stirring shaft 6103 through a flange, and a high-temperature resistant sealing gasket is provided on the flange surface.

[0052] Specifically, when the servo motor 6101 is started, the torque is amplified by the planetary gear set, driving the stirring shaft 6103 to rotate, driving the propeller blades 6202 and the parallel blades 6203 to operate synchronously, forming a radial and axial composite flow field.

[0053] The helix angle of the propeller blade 6202 is 15°-30°, the blade inclination angle of the parallel blade 6203 is 45°-60°, and the helical directions of two adjacent propeller blades 6202 are opposite.

[0054] Specifically, when the servo motor 6101 starts to drive the mixing component 62 to rotate, an orthogonal eddy current field is formed during the transportation process through the two propeller blades 6202 with opposite spiral directions, and turbulent shear force is generated while radially transporting the electrolyte, which is beneficial to promote the mixing of the solvent and the solute.

[0055] The drying carrying assembly 10 includes two mutually parallel clamping strips 1001 , a carrying frame 1002 is clamped between the two clamping strips 1001 , and the clamping strips 1001 are fixedly connected to the inner wall of the mixing box 1 .

[0056] Specifically, when the dry carrying assembly 10 is used, the molecular sieve is filled in the interior of the carrying frame 1002 . When the molecular sieve is replaced, the molecular sieve can be poured out by simply pulling out the carrying frame 1002 , which facilitates replacement of the molecular sieve.

[0057] The aeration protection assembly 5 includes a gas supply cylinder 501, a straight-through solenoid valve 502 is installed at the bottle mouth of the gas supply cylinder 501, a gas supply pipe 503 is fixedly installed at one end of the straight-through solenoid valve 502, and a plurality of nozzles 504 are threadedly connected to the top of the gas supply pipe 503. The gas supply cylinder 501 is clamped to the bottom layer of the multi-stage base 4, and the gas supply pipe 503 is fixedly connected to the mixing box 1. The gas supply cylinder 501 is compressed and filled with inert gas.

[0058] Specifically, during the electrolyte mixing process, the inert protective gas in the gas supply cylinder 501 enters the gas pipe 503 through the straight-through solenoid valve 502, and is then sprayed into the mixing box 1 through the nozzle 504 to protect the reaction system and prevent the reaction system from contacting oxygen and causing oxidation reaction, which would affect the quality of the electrolyte.

[0059] The vacuum recovery component 7 includes a vacuum air pump 701, the air inlet of the vacuum air pump 701 is connected to the interior of the mixing box 1 through a pipeline, the air outlet of the vacuum air pump 701 is connected to a three-way solenoid valve 702, one of the interfaces of the three-way solenoid valve 702 is connected to a return air cylinder 703, and the other interface of the three-way solenoid valve 702 is connected to the environment, the vacuum air pump 701 is clamped on the top layer of the multi-stage base 4, and the vacuum air pump 701 is fixedly installed inside the multi-stage base 4 and is located below the return air cylinder 703.

[0060] Specifically, after adding the solute to the mixing box 1, the interior of the mixing box 1 is vacuumed by the vacuum air pump 701, and the extracted air is discharged into the environment through the three-way solenoid valve 702 to prevent the oxygen and water vapor in the air from affecting the reaction system. When the solvent is added to the mixing box 1 and the stirring and mixing mechanism 6 is started, the vacuum air pump 701 extracts the inert protective gas in the mixing box 1 and fills it into the return air cylinder 703 through the three-way solenoid valve 702. Cooperating with the aeration protection component 5 is conducive to maintaining the stable air pressure inside the mixing box 1 and facilitating the recovery of the inert protective gas.

[0061] The inner wall of the mixing box 1 is provided with a polytetrafluoroethylene coating, and the contact parts between the inner wall of the box and the drying carrying component 10 and the aeration protection component 5 adopt an arc transition design. An integrated heating belt is provided inside the box body of the mixing box 1, and a PLC control panel is installed at the front of the top of the mixing box 1. A temperature sensor is installed in the center of the interior of the mixing box 1.

[0062] Specifically, the temperature of the reaction system is monitored by a temperature sensor, and the monitoring data is transmitted back to the PLC control panel. In a low temperature environment, the integrated heating belt is controlled by the PLC control panel to heat the interior of the mixing box 1, which is beneficial to maintaining the temperature of the reaction system.

[0063] A sealing clamp 2 is fixedly installed on the top of the mixing box 1 , a sealing plate 3 is clamped between the sealing clamp 2 and the mixing box 1 , and a sealing gasket is provided between the sealing plate 3 and the sealing clamp 2 .

[0064] A feeding port 8 is installed through the top of the sealing plate 3 , and a pressure gauge 9 is installed through the top of the sealing plate 3 and on one side of the feeding port 8 .

When adding solutes and additives, the dust cover is opened and the solutes and additives are added to the mixing box 1 through the feeding port 8. After the addition is completed, the dust cover is covered again, and the sealing plate 3 and the sealing clip 2 are used to seal the top of the mixing box 1 to ensure the sealing of the mixing box 1.

At the same time, it is convenient to intuitively monitor the pressure inside the mixing box 1.

[0066] A liquid discharge pipe 11 is fixedly installed at a position near the bottom of the mixing box 1 and away from the multi-stage base 4 .

[0067] Specifically, the drain pipe 11 has a built-in ceramic filter element and a solenoid valve connected to the bottom. After mixing is completed, inert protective gas is continuously introduced to maintain positive pressure. The electrolyte is filtered through the drain pipe 11 and then transported to the storage tank to facilitate the discharge of the electrolyte.

[0068] How it works

[0069] The molecular sieve is filled into the carrying frame 1002, and the solvent is first injected into the mixing box 1. The excess moisture is absorbed by the molecular sieve in the drying carrying component 10. Then, the vacuum recovery component 7 is started, and the vacuum air pump 701 evacuates the residual air in the box. Then, the aeration protection component 5 fills the box with inert protective gas, which is evenly distributed through the nozzle 504 to maintain a positive pressure environment and form an oxygen-free inert environment. After that, the solute and other additives are added to the mixing box 1 through the feeding port 8, and the stirring and mixing mechanism 6 is started to mix the solvent, solute and other additives. The servo motor 6101 amplifies the torque through the gear box 6102, drives the stirring shaft 6103 to rotate, and drives the stirring paddle 6104, propeller blades 6202 and parallel blades 6203 to operate synchronously. The propeller blades 6202 push the electrolyte radially to form a high-speed circulation flow, and the reverse propeller blades 6202 and parallel blades 6203 combine to produce a positive The cross-eddy flow field enhances the turbulent shear force and accelerates the diffusion of solutes, which is beneficial to accelerating the mixing of solvents, solutes and other additives and making them mix more evenly. While stirring and mixing, inert protective gas is continuously charged through the gas supply cylinder 501, the straight-through solenoid valve 502 and the gas pipe 503, and cooperates with the vacuum air pump 701, the three-way solenoid valve 702 and the return gas cylinder 703 to form a closed-loop system, which is beneficial to maintaining the pressure inside the mixing box 1 and recovering the inert protective gas. At the same time, while the inert protective gas is aerated and flowing inside the mixing box 1, it is beneficial to assist the stirring and mixing mechanism 6 to complete the stirring operation. The temperature sensor monitors the temperature inside the box in real time. The PLC control panel is linked to the integrated heating belt to start at low temperature to maintain the reaction temperature. The sealing plate 3 cooperates with the sealing card 2 to seal the top of the mixing box 1 to prevent external pollution.
