Sealing device used between cathode roller and anode tank in copper foil pickling

Abstract

The invention discloses a sealing device between a cathode roller and an anode tank in copper foil pickling, which comprises end heads mounted at two ends of the cathode roller and used for sealing and receiving water, and the cathode roller is rotatably connected between two mounting racks and positioned above the anode tank. And in the cleaning process, the dripped cleaning water can be absorbed by the absorption pipe on the first roller and the absorption holes in the end part head, so that the phenomenon that the cleaning water enters the anode tank is avoided. And the cleaning water which drifts away and is not absorbed falls into the water absorption sponge on the side face of the side plate and the water absorption sponge on the transverse plate at one end to be absorbed, and then enters the absorption holes in the absorption plate to be recycled. The cathode roller and the anode tank are fully sealed, so that cleaning water is prevented from entering the anode tank, copper sulfate in the anode tank is not diluted by the cleaning water, and the copper foil can be efficiently produced according to a preset standard.

Description

technical field [0001] The invention relates to a sealing device, in particular to a sealing device used between a cathode roll and an anode tank in copper foil pickling, and belongs to the field of copper foil production. Background technique [0002] After the copper foil comes out of the anode tank, since the rough surface of the copper foil still contains copper sulfate solution, the copper foil will be oxidized and blackened after contacting with air, so the copper foil on the cathode roll needs to be washed with water. [0003] In the production of existing copper foil, after the cathode roll is pickled and washed with water, due to the perfect sealing between the cathode roll and the anode tank, the cleaning water is easy to fall into the anode tank, and the cleaning water will not only destroy the sulfuric acid inside the anode tank The copper solution causes pollution, and the copper sulfate solution is diluted, so that the concentration of the copper sulfate soluti...
