Description
Technical Field

[0003] The main methods used in the current copper dissolving process are immersion and spraying. In the immersion copper dissolving process, although the copper sulfate solution can fully contact the raw copper plate or copper wire, a large amount of sulfuric acid solution is required.

In the spraying copper dissolving process, the raw copper plate or copper wire is fully in contact with the air, which has the advantages of less copper consumption, less capital occupation, low copper dissolving temperature, and less total liquid volume. It is the main copper dissolving process used by existing electrolytic copper foil companies.

[0020] As one of the basic materials of the electronics industry, electrolytic copper foil is mainly used to manufacture printed circuit boards (PCBs) and lithium-ion batteries, and is widely used in home appliances, communications, computing (3C), new energy industries, etc. Copper dissolution is an important step in the production process of electrolytic copper foil. It is to place the raw copper plate or copper wire in a copper dissolving tank, then add sulfuric acid and air into the copper dissolving tank to react, so that the raw copper plate or copper wire is dissolved into a copper sulfate solution.
[0021] The main methods used in the current copper dissolving process are immersion and spraying. In the immersion copper dissolving process, although the copper sulfate solution can fully contact the raw copper plate or copper wire, a large amount of sulfuric acid solution is required. In addition, due to the low air content in the solution, the air utilization rate is low, resulting in a slow copper dissolving reaction, and the solution needs to be continuously heated for a continuous reaction. In the spraying copper dissolving process, the raw copper plate or copper wire is fully in contact with the air, which has the advantages of less copper consumption, less capital occupation, low copper dissolving temperature, and less total liquid volume. It is the main copper dissolving process used by existing electrolytic copper foil companies. However, there are dead corners during spraying, which leads to insufficient contact between the sulfuric acid solution and the raw copper plate or copper wire, reducing the copper dissolving efficiency.
[0022] At present, in order to improve the efficiency of spray copper dissolution, some electrolytic copper foil manufacturers use atomization technology to atomize sulfuric acid solution at high temperature to achieve full contact between sulfuric acid and raw copper plates or copper wires. However, since sulfuric acid atomization requires continuous heating, the atomization operation is not only difficult, but also has high production costs.
[0023] Based on the above problems, an embodiment of the utility model provides a spray copper dissolving device, which places the copper material in full contact with the air through a sieve plate inside the tank body, and is then used in conjunction with the first barrel body and the first through hole on the annular tube. An external infusion pump can be used to evenly spray the acid solution on the surface of the copper material from both the inside and outside, which not only improves the spraying effect and avoids the occurrence of spraying dead corners, but also the multiple first through holes can increase the spraying speed and improve the copper dissolving efficiency.
