Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic refined copper production, in particular to a liquid level regulating device based on an electrolytic cell body. Background Art

[0002] The common process of electrolytic refining of copper is to cast the fire-refined copper into anode plates, use permanent stainless steel cathodes as cathode plates, alternately place them in electrolytic cells, and use an aqueous solution of copper sulfate and sulfuric acid as the electrolyte. Under the action of direct current, the copper on the anode will lose two electrons to generate -2 valent copper ions, while precious metals and certain metals are insoluble and become anode mud and precipitate at the bottom of the electrolytic cell. The -2 valent copper ions in the solution will precipitate preferentially on the cathode, while other base metals with more negative points cannot precipitate on the cathode and remain in the electrolyte to be removed when the electrolyte is regularly purified. The copper obtained in this way is of high purity and is called electrolytic copper.

[0003] The liquid supply of the electrolytic cell is mostly adopted in the form of bottom feeding and end overflow, and the overflowed electrolyte is collected and returned to the electrolytic cell. In the production process of copper electrolysis, the liquid level of the electrolytic cell needs to be adjusted at different process stages. The existing adjustment method is to directly achieve the purpose of adjusting the liquid level by controlling the closure and opening of the overflow port, but this method forms a siphon at the overflow port, and the liquid flow in the tank formed by the bottom liquid inlet and the top overflow is not conducive to the sedimentation of the anode mud. If the anode mud does not settle well, a small amount of anode mud may adhere to the cathode. Therefore, the applicant designed a liquid level regulating device to reduce the impact of overflow on the electrolyte. Utility Model Content

The chamber can be used to regulate the electrolyte. At the same time, the electrolyte enters from the bottom of the independent chamber before being discharged from the overflow port, thereby reducing the interference of the top overflow port on the sedimentation of the anode mud.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0011] Beneficial effects of the utility model:

[0012] Through the bottom discharge method of the independent cavity, the electrolyte first enters the independent cavity and then overflows and discharges, reducing the impact of the bottom-in and top-out liquid flow on the anode mud sedimentation.

A connecting port 5.1 is provided at the bottom of the sealing cavity plate 5, and a liquid partition plate 2 is movably inserted in the gap formed by the sealing cavity plate 5 and the cell body 1. When the liquid partition plate 2 rises, the connecting port 5.1 connects the cell body 1 to the independent cavity. After the liquid partition plate 2 drops, the connecting port 5.1 is blocked by the liquid partition plate 2, and the independent cavity is isolated from the cell body 1.

At this time, the independent cavity and the electrolytic cell will form the same liquid level. When the liquid level exceeds the overflow port 3.1, the electrolyte enters the control port inner tube 6 from the overflow port 3.1, and finally drains to the bottom of the overflow pipe 3. The discharge port 3.2 of the overflow pipe 3 discharges the electrolyte to the outside of the electrolytic cell. The control port inner tube 6 can close the overflow port 3.1 by rotating.
