Description

Technical Field

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

[0002] The electrolyte is a key component in an electrochemical system and has multiple different types. Its function is to achieve the conversion between electrical energy and chemical energy through ion transport. During the production and processing of the electrolyte, different raw material components need to be evenly mixed together by a mixing device; The patent document with the publication number "CN220003795U" discloses an "electrolyte mixing device, including an electrolyte tank body and a shunt box. The electrolyte tank body is a box structure with an open top. Disassembly and assembly components are installed at the top of both sides of the electrolyte tank body, and vertical plates are vertically fixed to the bottom surfaces of the disassembly and assembly components on both sides. By means of the vertical sliding fit of the mating seat and the mating groove and the horizontal sliding fit of the limit rod and the limit hole, a shunt box is detachably fixed at the lower part inside the electrolyte tank body. In this way, by introducing air into the shunt box and discharging it through evenly distributed air outlet holes, the electrolyte in the electrolyte tank body can be turbulently mixed and stirred by means of air. The layout method of the shunt box inside the electrolyte tank body is simple and easy to implement, replacing the stirring method of the stirring paddle rotating. The mixing range is not easily limited and is conducive to improving the mixing efficiency of the electrolyte." Although it replaces the stirring method of the stirring paddle rotating, the mixing range is not easily limited and is conducive to improving the mixing efficiency of the electrolyte, but in the actual preparation process of the electrolyte, different electrolytes correspond to different reaction systems, and the viscosities of different reaction systems are different. When the viscosity of the reaction system is relatively large, simply using the means of aeration cannot meet the mixing requirements, and the open mixing environment makes the reaction system easily affected by oxygen and moisture in the ambient air, resulting in side reactions and reducing the quality of the electrolyte.

One side of the gearbox 6102 is connected with a stirring shaft 6103. A plurality of stirring paddles 6104 are equidistantly installed on the outer circle of the stirring shaft 6103. The mixing component 62 is located between two adjacent stirring paddles 6104. The mixing component 62 includes a sleeve shaft 6201. A propeller blade 6202 is fixedly installed in the middle of the outer circle of the sleeve shaft 6201. A parallel blade 6203 is fixedly installed on the outer circle of the sleeve shaft 6201 and outside the propeller blade 6202. The sleeve shaft 6201 is fixedly connected with 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 in the middle layer of the multi-stage base 4.

[0028] Specifically, during the process of electrolyte mixing, the solvent is added to the mixing tank 1, and the excess moisture in the solvent is absorbed by the molecular sieve in the drying carrier assembly 10. The residual air in the mixing tank 1 is evacuated by the vacuum recovery assembly 7 to prevent the oxygen and moisture in the residual air from affecting the mixing of the solvent and solute. Then, an inert protective gas is filled into the mixing tank 1 through the aeration protection assembly 5. Next, the solvent and other additives are put into the mixing tank 1. After the servo motor 6101 is started, it drives the stirring shaft 6103 to rotate in cooperation with the gearbox 6102, thereby driving the stirring paddle 6104 and the sleeve shaft 6201 to rotate synchronously, and further driving the propeller blade 6202 and the parallel paddle 6203 to rotate, so as to drive the stirring of the solvent and solute. During the stirring process, the electrolyte is radially transported through the propeller blade 6202, making the mixing of the solvent and solute more uniform. During the mixing process of the solvent and solute, an inert protective gas is continuously introduced into the mixing tank 1 through the aeration protection assembly 5. While protecting the reaction system, it assists the stirring and mixing mechanism 6 to mix the solvent and solute, and the gas in the mixing tank 1 is extracted through the vacuum recovery assembly 7 to maintain the stable air pressure inside the mixing tank 1.

[0032] Specifically, when the servo motor 6101 is started to drive the mixing component 62 to rotate, an orthogonal eddy current field is formed during the transportation by two propeller blades 6202 with opposite helix directions, and a turbulent shear force is formed while radially transporting the electrolyte, which is beneficial to promoting the mixing of the solvent and solute.

[0033] The drying carrier assembly 10 includes two parallel clamping bars 1001, and a carrier frame 1002 is clamped between the two clamping bars 1001. The clamping bars 1001 are fixedly connected to the inner wall of the box body of the mixing tank 1.

[0034] Specifically, when using the drying carrier assembly 10, the molecular sieve is filled inside the carrier frame 1002. When replacing the molecular sieve, only the carrier frame 1002 needs to be pulled out to pour out the molecular sieve, which is convenient for replacing the molecular sieve.

The gas supply cylinder 501 is clamped with the bottom layer of the multi-stage base 4, the gas supply pipe 503 is fixedly connected with the mixing box 1, and the gas supply cylinder 501 is compressed and filled with inert gas.

[0036] Specifically, during the electrolyte mixing process, the inert protective gas in the gas supply cylinder 501 enters the gas supply 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 undergoing an oxidation reaction, which would affect the quality of the electrolyte.

[0037] 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.

[0038] Specifically, after adding the solute into the mixing box 1, the inside of the mixing box 1 is evacuated 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 gas cylinder 703 through the three-way solenoid valve 702. Cooperating with the aeration protection component 5 is beneficial to maintaining the stable air pressure inside the mixing box 1 and is convenient for recovering the inert protective gas.

[0039] 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 mixing box 1, a PLC control panel is installed at the front of the top of the mixing box 1, and a temperature sensor is installed in the center of the mixing box 1.

[0040] 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.

[0041] 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 .

[0042] 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 .

[0043] Specifically, the feeding port 8 is equipped with a quick-detachable dust cover. 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 card 2 are used to seal the top of the mixing box 1 to ensure the sealing of the mixing box 1. The pressure gauge 9 is used to monitor the pressure inside the mixing box 1 to prevent air from the external environment from entering the mixing box 1 and causing side reactions with the reaction system. At the same time, it is convenient to intuitively monitor the pressure inside the mixing box 1.

[0044] 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 .

[0045] 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.

[0046] How it works The molecular sieve is filled into the carrying frame 1002, and the solvent is first injected into the mixing box 1, and 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. Then, 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, the propeller blades 6202 and the 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 the 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 accelerate the mixing of solvents, solutes and other additives and make them mix more evenly. While stirring and mixing, the inert protective gas is continuously charged through the gas supply cylinder 501, the straight-through solenoid valve 502 and the gas pipe 503, and a closed-loop system is formed with the vacuum air pump 701, the three-way solenoid valve 702 and the return gas cylinder 703, which is beneficial to maintain the pressure inside the mixing box 1 and recover the inert protective gas. At the same time, while the inert protective gas is aerated and flows 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.
