Description

Technical Field

[0001] The utility model relates to the technical field of copper foil production, in particular to a liquid supply device. Background Art

[0002] In the copper foil production process, a liquid inlet box made of metal or plastic is usually used, which is connected to the anode tank of the foil production machine by bolts. The high-temperature copper sulfate solution is transported to the liquid inlet box through a pipeline and then distributed to the anode tank by the liquid inlet box.

[0003] In the prior art, liquid inlet boxes made of metal materials usually suffer from acid corrosion. If pure titanium is used, the cost is very high. Liquid inlet boxes made of plastic materials can effectively solve the corrosion problem, but high-temperature solutions can cause the plastic to soften and deform, leading to cracks and breakage in the welds, causing corrosive solutions to overflow, posing a great safety hazard. Adding partitions can enhance the rigidity of the liquid inlet box, but it will also lead to a narrow welding working space, increased welding difficulty, and easy welding leaks and cold welds, resulting in leakage in the liquid inlet box.
