Automatic cleaning device for crust breaking of aluminum electrolysis cell

Abstract

The invention aims to disclose an aluminum electrolysis cell crust breaking automatic cleaning device which comprises convex teeth, an installation fixing plate and a cleaning hammer mechanism, the convex teeth are fixed to the exposed part of a crust breaking hammer head, the installation fixing plate is installed on the side face of the crust breaking hammer head, the cleaning hammer mechanism is installed on the installation fixing plate, and the cleaning hammer mechanism is installed on the installation fixing plate. The convex teeth are connected with the cleaning hammer mechanism through a gear linkage mechanism; the shell head package can be automatically treated, the labor intensity of knocking the shell head package by an electrolyzer and replacing the shell breaking hammer head by a cell maintenance worker is greatly reduced, the phenomenon that the shell breaking mechanism cannot normally break the shell after the shell head package grows up is avoided, the service life of the shell breaking hammer head and the cylinder of the electrolytic cell is effectively prolonged, and the shell head package is convenient and easy to implement and is easy to realize under the existing conditions; online repairing is achieved, time is saved, cost is reduced, the method is not limited to crust breaking of the electrolytic cell, and the method can also be used for the similar working conditions of repeated knocking and extrusion cleaning of surface impurities in special environments in other industries.

Description

technical field [0001] The invention relates to an automatic cleaning device, in particular to an automatic cleaning device for shelling of aluminum electrolytic cells. Background technique [0002] The so-called shell hammer is essentially a cylindrical structure with a hollow upper part and a solid bottom made of Q235 cast iron, which is also commonly known as a shell hammer. [0003] The shell hammer will stick to part of the liquid electrolyte after each beat. Because the liquid electrolyte is highly viscous, and it is easy to solidify after cooling in the air. In normal production, each electrolytic cell has 6 sets of shelling mechanisms, and each group of shelling mechanisms beats shells once every 60 seconds on average. When the solid electrolyte completely wraps the shell head, causing the blanking and shelling system to fail to open the shell normally, the tank controller will send an alarm signal. [0004] At this time, the electrolyzer needs to use a hammer (5 ...

AI Technical Summary

Problems solved by technology

[0004] At this time, the electrolyzer needs to use a hammer (5 kg each) to slam the shell head bag to break the solid electrolyte and drop it. On average, each electrolyzer consumes one hammer per shift (8 hours per shift). Greatly increased the labor intensity of electrolyzers

At the same time, due to knocking, the shelling hammer head is damaged and its frequent
