The storage tank is connected to a pressurizing device via a vent pipe with a pressure gauge. A discharge pipe is connected to the bottom of the storage tank, and a heating wire is installed on the outer wall of the discharge pipe. An electrically controlled valve is connected to the connection between the discharge pipe and the storage tank. The advantages are: the stirring assembly agitates the electrolyte within the storage tank, and the vent pipe increases the internal pressure, facilitating the discharge of the electrolyte through the electrically controlled valve and the discharge pipe. The heating wire further heats the discharge pipe, ensuring complete discharge of the electrolyte.

[0003] After investigation and analysis, the patent has the following drawbacks in actual use:

[0004] Electrolyte needs to be kept in a closed state during storage to prevent liquid evaporation or oxidation. However, this device is equipped with a gas vent pipe on the storage tank. The design of the gas vent pipe may cause the electrolyte to come into contact with external gases during storage, increasing the risk of electrolyte evaporation or leakage, and affecting its stability and performance.

[0005] In summary, this application proposes an aluminum electrolytic capacitor electrolyte storage device to solve the aforementioned problems. Utility Model Content

[0026] Furthermore, the storage assembly also includes a top cover 5. The top cover 5 is snapped onto the top of the storage tank 2, and a sealing ring is provided inside the top cover 5. When the storage tank 2 needs to be disassembled, first remove the bolts on the annular bracket 4, then remove the top cover 5 from the storage tank 2, and then the storage tank 2 and the top cover 5 can be taken out as a whole. The design of the detachable storage tank 2 makes it more convenient for the device to be cleaned or maintained without disassembling the whole, reducing the difficulty of operation and time cost. At the same time, it allows users to quickly replace or adjust the storage tank according to actual needs to adapt to the storage and processing requirements of different electrolytes. The combination of the temperature control box 1 and the storage tank 2 can more accurately control the temperature of the electrolyte to ensure that it is stored in the best condition and avoid performance degradation caused by temperature fluctuations.

[0027] Furthermore, a support column is fixedly installed at the bottom of the storage tank 2, and the bottom end of the support column contacts the inner bottom of the temperature control box 1, which facilitates the support and fixation of the storage tank 2.

[0028] Furthermore, the temperature control box 1 and the annular bracket 4 are provided with interconnected threaded grooves, and bolts are installed in the threaded grooves. The temperature control box 1 and the annular bracket 4 are fixedly installed by bolts, which facilitates the fixation of the annular bracket 4, thereby making the storage tank 2 stable inside the temperature control box 1.

[0029] Furthermore, a motor 6 is fixedly installed on the top of the top cover 5, and the top of the rotating column 7 passes through the top cover 5 and is fixedly installed with the output shaft of the motor 6. A rotating plate 8 and a spiral blade 9 are fixedly installed on the outer wall of the rotating column 7. The rotating plate 8 is located above the spiral blade 9.

The movable block 11 can automatically adjust its position according to the change of the internal pressure of the storage tank 2. When the pressure exceeds the set value, the gas can be discharged through the gas guide pipe 14, avoiding the rupture of the temperature control box 1 or the leakage of electrolyte due to excessive pressure, which significantly improves the safety of the device. The combination structure of the pressure relief pipe 10 and the movable block 11 is simple, easy to install and maintain, reduces the complexity of the device and the cost of use, and can effectively prevent the electrolyte from being discharged with the gas, ensuring that the electrolyte will not be lost or pollute the environment due to the pressure relief operation, while reducing resource waste.

The temperature control box 1 keeps the electrolyte inside the storage tank 2 at room temperature. At the same time, the motor 6 is started, which drives the rotating column 7 to rotate. The rotating column 7 drives the rotating plate 8 and the spiral blade 9 to rotate, so that the rotating plate 8 and the spiral blade 9 stir and mix the electrolyte. When the internal pressure of the storage tank 2 is too high, the gas will drive the movable block 11 to slide upward, so that the gas can be discharged through the gas guide pipe 14. When it is necessary to disassemble the storage tank 2, first remove the bolts on the annular bracket 4, then remove the top cover 5 from the storage tank 2, and then the storage tank 2 and the top cover 5 can be taken out as a whole.
