Description

Technical Field

[0001] The utility model belongs to the technical field of copper foil processing, in particular to a structure for preventing an electrolytic copper foil dissolving tank from being blocked. Background Art

[0002] The copper dissolution process primarily prepares the copper sulfate electrolyte. As the first and most critical step in electrolytic copper foil production, pretreated copper material (typically bundled copper wire) is placed into a copper dissolution tank. Under continuous heating, air is pumped into the tank from below. Simultaneously, the system's circulating copper-depleted electrolyte is sprayed over the copper wires via a delivery pipeline. This reaction dissolves the copper material, ensuring a stable copper ion concentration in the electrolyte.

[0003] During the copper dissolution reaction, two conditions must be guaranteed: sufficient oxygen and full contact with the copper material, and the sprayed electrolyte can fully contact the copper material. In the actual production process, the copper wires above the titanium mesh are continuously dissolved by the electrolyte spray and squeezed by the over 100 tons of copper material added to the entire copper dissolution tank. There is a certain probability that the fine copper wires and copper slag will be compacted, resulting in a gradual decrease in the gaps, a reduction in the contact area between the electrolyte and the air, and there is a possibility of complete compaction, and partial blockage of the titanium mesh. Ultimately, during the electrolyte preparation process, problems such as inadequate copper dissolution reaction, reduced copper dissolution efficiency, and fluctuations in the copper ion content in the electrolyte will occur.

[0024] In this embodiment, when in use, the entire device is installed above the titanium mesh in the copper dissolving tank, and the copper wire is placed on the vertical grid 2. When the copper wire is processed, a portion of the electrolyte is sprayed onto the copper wire through the top of the copper dissolving tank, and at the same time, oxygen is introduced under the titanium mesh of the copper dissolving tank. Since the copper wire is placed on the vertical grid 2, this can effectively avoid the copper wire from directly contacting the titanium mesh, preventing the copper wire from forming a dense and void-free state due to extrusion, and allowing the electrolyte to better spray the copper wire. At the same time, since the gap is reduced and the amount of air introduced is reduced, the oxidation of the copper material is weakened and the copper dissolving rate is reduced. During processing, the electrolyte is introduced into the through cavity 3, and then sprayed out through the spray port 4, and then through the The protective mechanism sprays to the bottom of the copper wire, thereby providing additional electrolyte spraying at the bottom of the copper wire.
