Efficient cleaning device for etched foil and implementation method of device

Abstract

The invention discloses a high-efficiency cleaning device for corroding foil, comprising a foil feeding roller and a foil discharging roller, a cleaning hanger and a vibrating box hanger. The frame and the vibration box hanger are installed on the corresponding support plates, the left vibration box is installed on the vibration box hanger, the right vibration box is installed on the cleaning hanger, the left vibration box and the right vibration box are arranged oppositely, and the cleaning hanger is installed below. There are bottom rollers, the left vibration box and the right vibration box are each provided with a mesh cover, and the left vibration box and the right vibration box are each provided with outlet pipes, which are connected to the ultrasonic generator through the power line. There is a spray pipe, the spray pipe washes the corroded foil, and the outside of the left vibration box and the right vibration box is provided with a cleaning tank. The invention also discloses a realization method of a high-efficiency cleaning device for corroding foil. The invention has the characteristics of simple structure, low production cost, energy saving and environmental protection, good cleaning effect and high product performance.

Description

technical field [0001] The invention relates to the production technology of corroded foil, in particular to a high-efficiency cleaning device for corroded foil and its realization method. Background technique [0002] In large production lines for corrosion of anode foil and negative electrode foil for medium and high pressure and low voltage aluminum electrolysis, it is necessary to thoroughly clean the internal and external surface attachments (such as aluminum powder, chloride, etc.) of the cavity of the corroded foil. The traditional cleaning method is to use multiple groups of deionized water spray cleaning and countercurrent rinsing in multiple cleaning tanks, which has been used for decades. There are serious defects in traditional cleaning methods: the efficiency of water spray cleaning and countercurrent rinsing is too low, and the attachments on the surface of corroded foil are difficult to remove. This not only wastes pure water and space, increases production c...

AI Technical Summary

Problems solved by technology

There are serious defects in traditional cleaning methods: the efficiency of water spray cleaning and countercurrent rinsing is too low, and the attachments on the surface of corroded foil are difficult to remove.

This not only wastes pure water and space, increases production costs, but also affects the performance of corroded foil products

For example, corroded foil with a lot of aluminum powder is likely to cause ignition of the feeder roller during formation in the subsequent process, flash fire in the formation tank, pollution of the formation liquid, and easy production of aluminum hydroxide crystals. The formation efficiency is low and production is unstable, resulting in subsequent Road products have poor performance such as long boosting time of formed foil, large leakage current, more alumina powder and pits on the surface of formed foil
