Example

[0033] Please see Figure 1-7 This utility model provides a technical solution: a capacitor electrolyte purification and impurity removal device, including a storage tank 1 for storing capacitor electrolyte, the electrolyte being injected through a filling pipe 6 at the top of the storage tank 1, the storage tank 1 serving as a storage container to provide a stable liquid source for subsequent processing, a flexible hose 8 connected to the bottom of the storage tank 1, a tank body 2 fixed to one side of the storage tank 1, and a tank cover 3 bolted to the top of the tank body 2; a stirring assembly 7 for stirring the electrolyte is provided at the top of the storage tank 1; the filling pipe 6 is connected to the top of the storage tank 1, and the centrifugal pump 10 is stopped when the liquid level is below a threshold.

[0034] A centrifugal pump 10 is installed at the bottom of the inner wall of the storage tank 1. The outlet of the centrifugal pump 10 is connected to the inlet of the hose 8. The centrifugal pump 10 at the bottom of the storage tank 1 pumps the electrolyte into the inside of the tank cover 3 through the hose 8, and finally into the tank body 2. The flexible design of the hose 8 is adapted to the separation operation of the tank cover 3 and the tank body 2.

[0035] The stirring assembly 7 includes a motor 71, a rotating shaft 73 fixed to the output shaft end of the motor 71, and several stirring blades 72 fixed to the outside of the rotating shaft 73 inside the liquid storage tank 1. The motor 71 is fixed at the top center of the liquid storage tank 1, and the outside of the rotating shaft 73 is rotatably connected to the top axis of the liquid storage tank 1 through a sealed bearing. The motor 71 of the stirring assembly 7 drives the rotating shaft 73 to rotate, thereby driving the stirring blades 72 to stir the electrolyte in the liquid storage tank 1, promoting uniform mixing of the electrolyte, preventing impurities from settling, and ensuring subsequent filtration efficiency.

[0036] The inner side of the tank body 2 is equipped with a filter screen 11, which is used to remove impurities from the electrolyte. After the electrolyte enters the tank body 2, it passes through the built-in filter screen 11. The filter screen 11 intercepts solid particles or large molecular impurities in the electrolyte, achieving preliminary purification. The tank cover 3 is equipped with a connecting component 5 for disassembling and assembling the filter screen 11.

[0037] The bottom of the tank body 2 is connected to the liquid outlet pipe 9, which is used to transport the purified electrolyte to the purification process. The purified electrolyte is discharged from the liquid outlet pipe 9 at the bottom of the tank body 2 and enters the next purification process. The liquid outlet end of the hose 8 is connected to the inside of the tank cover 3.

[0038] The connecting assembly 5 includes two first fixing frames 51. The first fixing frame 51 has a sliding groove 510 inside. A sliding plate 54 is slidably connected to the inside of the sliding groove 510. A pull rod 52 and a locking rod 511 are fixed on both sides of the sliding plate 54 respectively. The top of the filter screen 11 is fixed with a second fixing frame 53. The second fixing frame 53 has two locking grooves 512 on its outer side.

[0039] A sealing gasket is adhered to the bottom of the can lid 3, and one side of the bottom of the sealing gasket is attached to the top of the can body 2. A sealing ring 55 is fixed to the top of the inner wall of the can lid 3. The sealing ring 55 is made of fluororubber and is resistant to electrolyte corrosion. The bottom of the sealing ring 55 is attached to the top of the second fixing frame 53. Several guide rods 56 are fixed to the top of the inner wall of the can lid 3. One end of the guide rod 56 has an arc surface. The outer side of the guide rod 56 is inserted into one side of the second fixing frame 53. When the filter screen 11 needs to be replaced or cleaned, pull the two pull rods 52 to drive the slide plate 54 to slide along the slide groove 510, compress the spring 57, and make the locking rod 511 disengage from the locking groove 512 of the second fixing frame 53. After loosening the connecting bolts between the can lid 3 and the can body 2, lift the can lid 3 upward. Through the guiding action of the guide rod 56, the second fixing frame 53 is separated from the can lid 3, and the filter screen 11 is removed simultaneously.

[0040] The outer side of the pull rod 52 extends through one side of the first fixing bracket 51. A spring 57 connects the slide plate 54 and the slide groove 510. A cover plate is bolted to one side of the first fixing bracket 51. After removing the bolts, the cover plate can be removed to maintain the spring 57. The two first fixing brackets 51 are fixed to both sides of the can lid 3. When the locking rod 511 is inserted into the inner side of the locking groove 512, the second fixing bracket 53 and the filter screen 11 are connected to the can lid 3. When the locking rod 511 leaves the inner side of the locking groove 512, the second fixing bracket 53 and the filter screen 11 are disassembled from the can lid 3. During installation, the second fixing bracket 53 is inserted into the can lid 3 along the guide rod 56 so that the locking groove 512 is aligned with the locking rod 511. The pull rod 52 is released, the spring 57 returns to its original position and pushes the slide plate 54, so that the locking rod 511 automatically inserts into the locking groove 512, completing the fixing. The sealing ring 55 and the sealing gasket ensure that there is no leakage at the connection. The sealing gasket at the bottom of the can lid 3 fits against the top of the can body 2 to prevent electrolyte leakage. The sealing ring 55 forms a secondary seal between the can lid 3 and the second fixing bracket 53, improving the overall sealing performance of the device. The guide rod 56 ensures that the filter screen 11 is accurately aligned during installation to avoid displacement that affects the filtration effect.

[0041] Working principle: The electrolyte is added to the storage tank 1 through the filling pipe 6. The bottom of the storage tank 1 is connected to the hose 8, and its outlet end is connected to the inside of the tank cover 3 to ensure that the electrolyte can directly enter the tank body 2. The bottom of the tank body 2 is connected to the outlet pipe 9, which is used to transport the purified electrolyte to the subsequent purification process. A centrifugal pump 10 is installed at the bottom of the inner wall of the storage tank 1. Its inlet end draws in the electrolyte, and its outlet end is connected to the hose 8. After the centrifugal pump 10 is started, it transports the stirred electrolyte to the tank body 2 through the hose 8.

[0042] A motor 71 is fixed at the center of the top of the storage tank 1. Its output shaft is connected to a rotating shaft 73. Multiple sets of stirring blades 72 are installed on the outside of the rotating shaft 73. The rotating shaft 73 is rotatably connected to the top of the storage tank 1 through a sealed bearing to ensure sealing. When the stirring assembly 7 is working, the motor 71 drives the rotating shaft 73 to rotate, and the stirring blades 72 fully stir the electrolyte to prevent precipitation or stratification and improve the uniformity of the electrolyte.

[0043] A filter screen 11 is installed inside the tank body 2 to intercept solid impurities in the electrolyte. After the electrolyte enters the tank body 2, it is filtered through the filter screen 11 to remove impurities. The impurities are trapped on the filter screen 11, and the clean electrolyte is discharged through the outlet pipe 9.

[0044] When the filter screen 11 needs maintenance, pull the lever 52 to move the slide plate 54 to slide in the slide groove 510, compress the spring 57, and make the locking lever 511 leave the inside of the locking groove 512. At this time, the second fixing bracket 53 and the filter screen 11 can be removed from the can cover 3, and the filter screen 11 can be taken out for cleaning or replacement.

[0045] Pull the lever 52 to move the slide plate 54 in the slide groove 510, compress the spring 57, and retract the locking rod 511; align the second fixing bracket 53 with the guide rod 56 and insert it into the can lid 3 until the sealing ring 55 is attached to the top of the second fixing bracket 53; release the lever 52, and under the action of the spring 57, the locking rod 511 is inserted into the locking groove 512, thus connecting the second fixing bracket 53 and the filter screen 11 to the can lid 3.

[0046] In summary, by installing a stirring assembly 7 at the top of the storage tank 1, and using a motor 71 to drive the rotating shaft 73 to rotate, the stirring blades 72 are driven to fully stir the electrolyte, effectively preventing electrolyte precipitation or stratification, thereby improving the uniformity of the electrolyte. A filter screen 11 is installed inside the tank 2. After the electrolyte enters the tank 2, it passes through the filter screen 11 to remove impurities. Impurities are trapped on the filter screen 11, and the clean electrolyte is discharged through the outlet pipe 9. This effectively removes solid impurities from the electrolyte and improves the purity of the electrolyte.

[0047] Pulling the lever 52 causes the slide plate 54 to slide, compressing the spring 57 and causing the locking rod 511 to disengage from the locking groove 512. This allows the second fixing bracket 53 and the filter screen 11 to be easily removed from the can lid 3 for cleaning or replacement, greatly simplifying the maintenance process of the filter screen 11. When installing the second fixing bracket 53, the sealing ring 55 adheres to the top of the second fixing bracket 53, ensuring the seal between the can lid 3 and the second fixing bracket 53, preventing electrolyte leakage, and ensuring the safe operation of the equipment. The entire maintenance process can be completed simply by pulling and releasing the lever 52. The operation is simple and easy to understand, reducing the skill requirements for operators and improving the operability of the work.
