[0031] The bottom of the high-position electrolytic cell 1 is connected to a main pipeline 4, and the other end of the main pipeline 4 is connected to a plurality of branch pipelines 5, and the plurality of branch pipelines 5 are located above the plurality of low-position electrolytic cells 3, and the plurality of branch pipelines 5 correspond to the plurality of low-position electrolytic cells 3 one by one, and a partition 6 is provided between two adjacent low-position electrolytic cells 3, and a through hole 17 is provided at the bottom of the partition 6;
[0032] A plurality of low-position electrolytic cells 3 are provided with empty slots 7 on one side, a bottom plate 16 is provided at the bottom of the plurality of low-position electrolytic cells 3 and the empty slots 7, the left end of the bottom plate 16 is tilted downward, the empty slot 7 is located at the left end of the bottom plate 16, a partition plate 2 8 is provided between the empty slot 7 and the adjacent low-position electrolytic cell 3, a through hole 2 is provided at the bottom of the partition plate 2 8, an overflow hole is provided on the other side of the empty slot 7, an adjustment component is provided on the inner side of the overflow hole, an overflow pipe 9 is connected to the outer side of the overflow hole, and the circulation pool 2 is provided below the overflow pipe 9;
[0033] The circulation pool 2 is connected to the high-position electrolytic cell 1 through a reflux pipe 10 , and a reflux pump is provided on the reflux pipe 10 .
[0034] In addition, the regulating assembly includes a flat plate 11, a connecting pipe 12 and a regulating pipe 13. One side of the flat plate 11 is fixedly connected to the inner wall of the empty slot 7. The flat plate 11 is located below the overflow hole. The other three sides of the flat plate 11 are surrounded by baffles 14. The lower end of the connecting pipe 12 is provided with a liquid inlet hole. The upper end of the connecting pipe 12 is provided with a thread 1 after passing through the flat plate 11. The lower end of the regulating pipe 13 is provided with a thread 2 matching the thread 1. The upper end of the regulating pipe 13 is provided with a liquid outlet. The height of the liquid outlet is greater than or equal to the height of the overflow hole. The height of the liquid outlet can be adjusted by rotating the regulating pipe 13. The height of the liquid level in the low-level electrolytic cell 3 is equal to the height of the liquid outlet. Therefore, the height of the liquid level in the low-level electrolytic cell 3 can be adjusted by rotating the height of the regulating pipe 13.
[0035] Specifically, a certain distance is set between the plate 11 and the overflow hole, so that the electrolyte coming out of the regulating pipe 13 can be buffered by the plate 11 first, and then flow out from the overflow pipe 9, so that the water surface of the electrolyte overflow process is smooth.

[0039] In this embodiment, the branch pipe 5 and the via 17 are respectively located at the front and rear sides of the low-position electrolytic cell 3, so that the electrolyte can be fully integrated in the low-position electrolytic cell 3, thereby further ensuring that the electrolyte concentration inside the multiple low-position electrolytic cells 3 is the same.

[0041] Since the bottom plate 16 is tilted, the electrolyte will pass through the through hole 17 at the bottom of the front side of the partition 16, flow downward, and then flow into the empty slot 7 through the through hole 2. At this time, impurities and other particles in the electrolyte are enriched in the empty slot 7 and are regularly discharged through the discharge valve 15.
[0042] The electrolyte in the empty tank 7 enters from the liquid inlet at the lower end of the connecting pipe 12, flows out through the liquid outlet on the regulating pipe 13, and then flows into the circulation tank 2 through the overflow pipe 9;
[0043] The electrolyte in the circulation pool 2 flows back to the high-level electrolytic cell 1 through the reflux pipe 10, thus completing the circulation of the electrolyte; during the electrolyte circulation process, the utility model ensures that the electrolyte concentrations in the multiple low-level electrolytic cells 3 are the same, and the thickness of the electrolyzed indium skin is uniform.
