Description

Technical Field

[0001] This utility model relates to the field of lithium-ion battery electrolyte preparation technology, and in particular to a lithium-ion battery material electrolyte mixing reactor. Background Technology

[0002] Lithium-ion battery electrolytes contain ethylene carbonate, dimethyl carbonate, ethyl methyl carbonate, and diethyl carbonate as main solvents. During processing, a mixing reactor is required to mix the electrolyte. Existing electrolyte mixing reactors cannot accurately measure the mixing process; excessive stirring leads to resource waste, while insufficient stirring results in incomplete mixing. Therefore, a lithium-ion battery material electrolyte mixing reactor is proposed. Utility Model Content

[0003] To address at least one of the aforementioned technical shortcomings, this utility model provides a lithium-ion battery material electrolyte mixing reactor, comprising: a support frame, a mixing cylinder, a stirring assembly, a feeding assembly, and a valve. The mixing cylinder is fixed in the middle of the support frame, the stirring assembly is fixed in the top of the support frame with its stirring end extending into the interior of the mixing cylinder, the top of the mixing cylinder has a feed inlet, the top of the support frame is fixedly connected to the feeding assembly, the discharge end of the feeding assembly is connected to the feed inlet, the bottom of the top of the mixing cylinder is fixedly connected to a discharge outlet, a valve is provided on the discharge outlet, and a detection assembly communicating with the interior of the mixing cylinder is fixedly connected to the outer wall of the mixing cylinder.

[0004] Furthermore, the detection assembly includes a conductivity meter fixed to the outer wall of the mixing cylinder, and a T-shaped tube sealed and connected to the mixing cylinder. The middle end of the T-shaped tube is sealed and connected to the mixing cylinder and communicates with the interior of the mixing cylinder. Electrodes are integrally connected to both ends of the T-shaped tube, and a wire for energizing detection is provided between the electrodes and the conductivity meter.

[0005] Furthermore, a sealing ring is fixedly connected to the outer wall of the middle end of the T-shaped tube, and the sealing ring is sealed to the outer wall of the mixing cylinder.

[0006] Furthermore, a solenoid valve is fixedly connected to the middle of the T-shaped tube.

[0007] Furthermore, the support frame includes at least three support rods, with a clamp fixed to the outer wall of the mixing drum at the middle of the three support rods, and a support plate fixed to the top of the three support rods. The feeding assembly is fixed to the upper surface of the support plate.

[0008] Furthermore, the stirring assembly includes a reducer and a motor fixed on the support plate. The output end of the motor is connected to the input end of the reducer. A rotating shaft is rotatably connected to the middle of the support plate. The rotating shaft extends through the middle of the support plate and the top of the mixing cylinder to the interior of the mixing cylinder. The top end of the rotating shaft is connected to the output end of the reducer. Several stirring rods are uniformly fixedly connected to the outer wall of the rotating shaft.

[0009] Furthermore, the angle between the middle end of the T-shaped tube and the outer wall of the mixing cylinder is less than 90°. Beneficial effects

[0010] When mixing lithium-ion battery materials to form an electrolyte, the feeding component introduces the raw materials, the stirring component mixes them, and the detection component detects the conductivity of the mixed solution to determine the degree of mixing.

[0011] By using a solenoid valve, the solution in the middle of the T-tube can be cut off before testing, so that the conductivity meter only measures the conductivity of the solution inside the T-tube.

[0012] When the solution inside the mixing drum is drained, the solution inside the T-tube will naturally flow back into the mixing drum and be drained together, thus preventing liquid accumulation inside the T-tube.

[0013] The purpose, features, and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Attached Figure Description

Detailed Implementation

[0021] Please refer to Figures 1 to 6 ;

[0022] This embodiment provides a lithium-ion battery material electrolyte mixing reactor, referenced... Figure 1 The system includes: a support frame 1, a mixing cylinder 2, a stirring assembly 3, a feeding assembly 4, and a valve 6. The mixing cylinder 2 is fixed in the middle of the support frame 1. The stirring assembly 3 is fixed in the top of the support frame 1, with the stirring end extending into the interior of the mixing cylinder 2. The top of the mixing cylinder 2 is provided with a feed inlet 201. The top of the support frame 1 is fixedly connected to the feeding assembly 4. The discharge end of the feeding assembly 4 is connected to the feed inlet 201. The bottom of the top of the mixing cylinder 2 is fixedly connected to a discharge outlet 202. A valve 6 is provided on the discharge outlet 202. A detection assembly 5, which communicates with the interior of the mixing cylinder 2, is fixedly connected to the outer wall of the mixing cylinder 2.

[0023] In practice, when mixing lithium-ion battery materials to form an electrolyte, the feeding component 4 introduces the raw materials, the stirring component 3 stirs and mixes them, and the detection component 5 detects the conductivity of the mixed solution to determine the degree of mixing.

[0024] If the conductivity is less than the target value, the mixing is insufficient; if the conductivity is greater than or equal to the target value, the mixing is sufficient.

[0025] Different electrolytes have different target values.

[0026] The support frame 1, mixing cylinder 2, stirring assembly 3, feeding assembly 4, and valve 6 all adopt existing technologies.

[0027] Further reference Figures 2 to 4 The detection component 5 includes a conductivity meter 501 fixed on the outer wall of the mixing cylinder 2, and a T-shaped tube 502 sealed and connected to the mixing cylinder 2. The middle end of the T-shaped tube 502 is sealed and connected to the mixing cylinder 2 and communicates with the interior of the mixing cylinder 2. The other two ends of the T-shaped tube 502 are integrally connected with electrodes 521. A wire 504 for energizing detection is provided between the electrodes 521 and the conductivity meter 501.

[0028] In practice, when testing the solution inside the mixing cylinder 2, the solution flows into the interior of the T-shaped tube 502 from the middle end of the T-shaped tube 502. The conductivity meter 501 energizes the two electrodes 521 through the wire 504, and obtains conductivity data through the conductivity meter 501 to determine the degree of mixing.

[0029] Further reference Figure 5 A sealing ring 522 is fixedly connected to the outer wall of the middle end of the T-shaped tube 502, and the sealing ring 522 is sealed to the outer wall of the mixing cylinder 2.

[0030] In practical implementation, the sealing ring 522 is used to prevent leakage at the connection between the T-shaped tube 502 and the mixing cylinder 2.

[0031] Further reference Figure 4 A solenoid valve 503 is fixedly connected to the middle of the middle end of the T-shaped tube 502.

[0032] In practical implementation, by setting the solenoid valve 503, the solution in the middle of the T-tube 502 can be cut off before the test, so that the conductivity meter 501 only measures the conductivity of the solution inside the T-tube 502.

[0033] Further reference Figure 2 The support frame 1 includes at least three support rods 101. The middle of the three support rods 101 is fixedly connected to a clamp 102 fixed to the outer wall of the mixing cylinder 2. The top of the three support rods 101 is fixedly connected to a support plate 103. The feeding assembly 4 is fixed to the upper surface of the support plate 103.

[0034] In practice, the support frame 1 is set up so that the mixing cylinder 2 can be kept away from the ground, so that the discharge port 202 can better discharge the electrolyte.

[0035] Further reference Figure 6 The stirring assembly 3 includes a reducer 303 and a motor 304 fixed on the support plate 103. The output end of the motor 304 is connected to the input end of the reducer 303. A rotating shaft 301 is rotatably connected in the middle of the support plate 103. The rotating shaft 301 extends through the middle of the support plate 103 and the top of the mixing cylinder 2 to the interior of the mixing cylinder 2. The top end of the rotating shaft 301 is connected to the output end of the reducer 303. Several stirring rods 302 are uniformly fixedly connected to the outer wall of the rotating shaft 301.

[0036] In practice, when stirring, the output of motor 304 drives reducer 303 to work, and the output of reducer 303 drives shaft 301 to rotate, so that shaft 301 stirs the solution inside mixing cylinder 2 through stirring rod 302.

[0037] Furthermore, the angle between the middle end of the T-shaped tube 502 and the outer wall of the mixing cylinder 2 is less than 90°.

[0038] In practice, when the solution inside the mixing cylinder 2 is discharged, the solution inside the T-shaped tube 502 will naturally flow back into the mixing cylinder 2 and be discharged together, thus avoiding liquid accumulation inside the T-shaped tube 502.
