Abstract
Description
Technical Field
[0001] This utility model relates to the field of copper electrolysis technology, specifically to a copper electrolyte filtration device. Background Technology
[0002] In the electrolytic copper production process, the electrolyte is a crucial medium, and its quality and purity directly affect the yield and quality of the electrolytic copper. During production, various impurities accumulate in the electrolyte, such as suspended solids, organic matter, and metal ions. These impurities not only reduce electrolysis efficiency but also significantly increase the contamination of the cathode copper by the electrolyte and suspended solids, thereby lowering its quality. Therefore, regular or continuous filtration of the electrolyte is essential to remove these impurities. Existing electrolyte filtration devices are often simple in structure, and when dealing with large volumes of electrolyte, they frequently suffer from slow filtration speeds and incomplete impurity removal, impacting both production efficiency and product quality.

The first pipe is equipped with a first valve and is connected to the inlet of the supernatant storage tank. The outlet of the supernatant storage tank is connected to the inlet of the plate and frame filter, and the outlet of the plate and frame filter is connected to the inlet of the second circulation tank. The second pipe is equipped with a second valve and is connected to the inlet of the second circulation tank. The outlet of the second circulation tank is located at the bottom of the second circulation tank and is connected to the inlet of the fine filter.

[0018] In one embodiment of this utility model, multiple plate and frame filters 3 are provided, and the multiple plate and frame filters 3 are connected in parallel.
[0019] In one embodiment of the present invention, an electrolyte pump is provided between the first circulation tank 6 and the high-level tank 7 to pump the electrolyte in the first circulation tank 6 to the high-level tank 7.

[0023] During normal electrolytic copper production, the electrolyte in electrolytic cell 1 is filtered in batches. The first valve 8 is closed and the second valve 9 is opened; the electrolyte in electrolytic cell 1 enters the second circulation tank 4 through the second pipe; the electrolyte in the second circulation tank 4 enters the fine filter 5 through the outlet to remove impurities, and the purified electrolyte returns to the second circulation tank 4, and so on; the supernatant in the second circulation tank 4 flows out through the overflow port at the top of the second circulation tank 4 and flows into the first circulation tank 6; the purified electrolyte in the first circulation tank 6 is pumped by the electrolyte pump to the high-level tank 7, and finally flows back to electrolytic cell 1 to continue electrolytic copper production.

The electrolyte in electrolytic cell 1 first enters the supernatant storage tank 2 through the first pipe. The electrolyte in the supernatant storage tank 2 enters the plate and frame filter 3 for filtration and then enters the second circulation tank 4. The electrolyte in the second circulation tank 4 enters the fine filter 5 through the outlet for filtration to remove impurities. The purified electrolyte returns to the second circulation tank 4, and this process is repeated. The supernatant in the second circulation tank 4 flows out through the overflow port at the top of the second circulation tank 4 and flows into the first circulation tank 6. The purified electrolyte in the first circulation tank 6 is pumped to the high-level tank 7 by the electrolyte pump and finally flows back to the electrolytic cell 1 to await the next copper electrolysis production.
