Description

Technical Field

[0001] This utility model relates to the technical field of electrolytic cell devices, specifically to a copper electrolytic cell liquid level regulating device. Background Technology

[0002] Electrolytic refining of copper, also known as hydrometallurgy, involves casting pyrometallurgically refined copper into anode plates and using pure copper sheets or permanent stainless steel as cathode plates, alternating these in an electrolytic cell. An aqueous solution of copper sulfate and sulfuric acid is used as the electrolyte. Under the influence of direct current, copper on the anode and the more negatively charged base metal undergo electrochemical dissolution and enter the electrolyte. Copper ions gain electrons at the cathode and are deposited, yielding the product, cathode copper. During the electrolytic refining process, the electrolyte level in the electrolytic cell needs to be adjusted according to the production cycle to maintain uniform electrolyte circulation, control electrolyte composition and temperature, reduce impurity migration and anode mud disturbance, and control the appearance quality of the cathode copper. Existing level adjustment devices lack a fixed adjustment range and require manual control. With numerous electrolytic cells and inconsistent levels due to different operators, the normal production of cathode copper and the quality of the anode mud are affected. Utility Model Content

[0003] To address the problem that existing liquid level regulating devices cannot fix the adjustment amount, this utility model provides a liquid level regulating device for copper electrolytic cells.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A copper electrolytic cell level regulating device includes an upper tube and a lower tube. The outer wall of one end of the upper tube has a first annular stepped protrusion, the stepped horizontal surface of which faces the other end of the upper tube. Each stepped horizontal surface of the annular stepped protrusion has a groove. The other end of the upper tube has a first annular groove, within which a first annular sealing ring is disposed. The outer wall of one end of the lower tube has a second annular stepped protrusion that matches the first annular stepped protrusion. The stepped horizontal surface of the second annular stepped protrusion faces away from the other end of the lower tube. Each stepped horizontal surface of the second annular stepped protrusion has a protrusion that matches the groove. The other end of the lower tube has an inwardly cutting portion, the surface of which has two second annular grooves, each containing a second annular sealing ring. The inner diameter of the second annular stepped protrusion is larger than the outer diameter of the upper tube. The end of the upper tube with the first annular groove is inserted into the central hole of the second annular stepped protrusion.

[0006] In one embodiment of the present invention, the other end of the upper tube is provided with two of the first annular grooves.

[0007] In one embodiment of this utility model, the groove is a circular groove, and the protrusion is a circular protrusion that matches the groove.

[0008] In one embodiment of this utility model, the first annular sealing ring and the second annular sealing ring are made of rubber.

[0009] In one embodiment of the present invention, the cross-sectional diameter of the first annular sealing ring is greater than the depth of the first annular groove; the cross-sectional diameter of the second annular sealing ring is greater than the depth of the second annular groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention provides a copper electrolytic cell liquid level adjustment device. By setting up a stepped protrusion and groove that can fit precisely, it achieves mechanical positioning and multi-stage locking of the upper and lower pipe connection. The plug-in structure of the upper and lower pipes, combined with the standardized stepped spacing, allows for quantitative adjustment of the liquid level, completely solving the problem of inconsistent adjustment in existing devices. It effectively eliminates liquid level adjustment deviations caused by manual operation and ensures the consistency of liquid level in each electrolytic cell. The matching structure of the protrusion and groove and the double sealing ring design significantly improve the sealing performance of the device in strong acid and high temperature environments, preventing composition fluctuations caused by electrolyte leakage. This device can ensure the stability of electrolyte circulation, reduce the impact of impurity migration on the quality of cathode copper, and significantly reduce the abnormal grade of anode mud caused by liquid level fluctuations, thereby improving the overall automation level and product qualification rate of the copper electrolytic refining process.
