Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic copper foil manufacturing, in particular to an anode tank structure. Background Art

[0002] Electrolytic copper foil is generally produced by a continuous process using a roller cathode and an insoluble anode. Electrolytic copper foil is generally formed by the deposition of copper ions in the electrolyte on a rotating cathode roller. The cathode roller can be made of a smooth titanium plate. The cathode roller is placed in the anode tank, and the insoluble anode is fixed on the inner arc surface of the anode tank. In the anode tank, a titanium plate with an iridium coating is usually used as the anode plate, that is, as an insoluble anode.

[0003] In the process of manufacturing electrolytic copper foil, in order to quickly add electrolyte to the anode tank, a liquid inlet is usually added to the bottom of the anode tank so that copper sulfate solution can be replenished online through the liquid inlet. When the copper sulfate solution is replenished into the anode tank through the liquid inlet, the copper sulfate solution often impacts the cathode roller through the liquid inlet, generating a vortex, which then impacts the anode plate. After the coating on the anode plate is impacted by the vortex, the coating of the anode plate is consumed too quickly, greatly increasing the material cost of the electrolytic copper foil. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the defect that in the process of producing electrolytic copper foil, when copper sulfate solution is added to the anode tank through the liquid inlet, the copper sulfate solution impacts the cathode roller through the liquid inlet, generating a vortex, and then the vortex impacts the anode plate, the coating of the anode plate is consumed too quickly, and the material cost of the electrolytic copper foil is greatly increased.

[0009] Optionally, the bottom outer wall of the anode tank body is semicircular, and the liquid inlet is located in the middle of the bottom of the anode tank body; the inclination direction of the slope is tangent to a circle concentric with the bottom outer wall of the anode tank body.

[0010] Optionally, the slope has an inclination angle of 4° to 8° relative to the horizontal direction.

[0011] Optionally, the length of the slope is the same as the width of a single anode plate.
