Description
Technical Field
The utility model relates to the technical field of lithium electric copper foil production, in particular to an anode groove with adjustable polar distance.
Background
The production process of the lithium electric copper foil comprises three parts of copper dissolution, foil production and cutting, wherein the electrolyte obtained by the copper dissolution is subjected to a series of chemical reactions by the foil production to obtain a copper foil parent roll, and the parent roll is cut according to the requirements of customers, so that copper foil small rolls with different specifications are obtained. In the foil producing section, the anode plate of the anode tank is normally electrified, the cathode roller is used as a cathode, the surface of the cathode roller is electrodeposited to generate copper foil, and finally the copper foil is peeled off from the surface of the cathode roller through the peeling roller. In this link, the distance between the cathode roller and the anode plate is called the electrode distance of the cathode and the anode, and is a key factor affecting the product quality of the electrolytic copper foil. Generally, when the polar distance is increased, the cathode polarization is increased, which is favorable for generating compact and fine copper grains by electrodeposition, thereby improving the quality of the copper foil, but increasing the polar distance reduces the current efficiency, improves the voltage, and further generates more energy consumption and cost; when the polar distance is reduced, the cathode polarization is reduced, the crystal grains are generated to be coarse, the copper foil is easy to generate quality defects, but the cell body voltage can be reduced, and the energy consumption and the cost are reduced. The electric energy cost occupies a relatively large area in the actual production of the electrolytic copper foil, so that the proper cathode-anode electrode distance is selected according to the product quality and the production cost, the electrode distance is reduced on the premise of ensuring the copper foil quality, and the production cost is reduced, which is particularly important.
However, the electrode distance between the cathode roller and the anode plate used in the electrolytic copper foil industry cannot be flexibly adjusted, and the adjustment thinking is that the installation height of the cathode roller is usually increased or decreased, so that uniformity cannot be ensured by the adjustment mode. Because the cathode roller and the anode groove are in a concentric circle structure when the equipment is installed, the cathode roller is raised or lowered by a certain height on the basis, and the distances from each point of the arc-shaped anode groove to the cathode roller are inconsistent. The use of such an adjustment method in actual production may cause uneven current density distribution in the longitudinal direction of the cathode roll, resulting in poor longitudinal uniformity of the copper foil.
Therefore, there is a need to provide an anode tank with adjustable pole pitch to solve the above-mentioned technical problems.
Disclosure of Invention
In order to solve the technical problem that the cathode roller and the anode plate cannot be concentric due to the fact that the distance between the cathode roller and the anode plate is adjusted by lifting the cathode roller when the copper foil is electrolyzed, and therefore uniformity of the copper foil on the cathode roller can be reduced, the utility model provides an anode tank with adjustable polar distance.
