Description

Technical Field

[0002] At present, in the environment where the country vigorously advocates energy conservation and emission reduction, around the strategic goals of "carbon neutrality and carbon peak", the iteration of high-end equipment process technology and the improvement of production efficiency will become an inevitable trend. At the same time, this will also become the future development direction of equipment companies. The foil machine, as a key equipment in copper foil production, directly affects the production efficiency, product quality and economic benefits of copper foil. Therefore, it has always been the core and focus of copper foil companies. With the vigorous development of new energy lithium batteries and the demand for ultra-thin copper foil, large-diameter and wide electrolytic equipment has become the main way to improve copper foil production efficiency.

[0003] Some structures of the existing tank body, such as the distribution of the holes in the anode plate and the liquid feeding mechanism, have more or less some defects, which will cause certain damage to the distribution of the electric field, the service life of the anode plate, and the surface density of the copper foil. The surface density of the copper foil is a key indicator for measuring the quality of the copper foil. Uneven surface density will form bubble gauze, resulting in degradation of the copper foil. Under the same conditions, the foil production efficiency of the Φ3300x1380 raw foil machine is about 22% higher than that of the Φ2700x1380 raw foil machine, which can greatly improve the production efficiency of copper foil enterprises, reduce production costs, reduce energy consumption, reduce environmental pollution, comply with national environmental protection policies, and also help to enhance the core competitiveness of enterprises.

The basic concept of the technical solution adopted by the present invention is: A novel anode cell for electrolytic copper foil comprises a liquid return box assembly, an arc-shaped rib plate, an anode mother plate, a side plate crosspiece, a side exhaust box, and a side plate assembly.
