Device for reducing growth of aluminum electrolysis shell head package

Abstract

The invention aims to disclose a device for reducing growth of an aluminum electrolysis shell head package, which comprises a protective sleeve, the protective sleeve is arranged on two sides of a shell breaking hammer head, and an inverted conical protective sleeve is arranged on the outer side of the bottom of the protective sleeve; compared with the prior art, 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, meanwhile, the phenomenon that the shell breaking mechanism cannot normally break a shell after the shell head package grows up is avoided, the service life of the shell breaking hammer head and the air cylinder of the electrolytic cell is effectively prolonged, and the shell breaking device is convenient and easy to implement; the method is easy to implement under the existing conditions, achieves online repair, saves time and reduces cost, is not limited to crust breaking of the electrolytic cell, and can be used for other industries to remove surface impurities in special environments through the resonance principle and other similar working conditions, and the purpose of the method is achieved.

Description

technical field [0001] The invention relates to a device for reducing the growth of shell heads, in particular to a device for reducing the growth of aluminum electrolysis shells. Background technique [0002] The aluminum electrolytic shelling system is composed of shelling cylinder and shelling hammer. The shell hammer is a cylindrical structure with a hollow upper part and a solid bottom made of Q235 cast iron. The hollow part and the solid part are integrated by welding, fixed at the bottom of the cylinder with a snap ring, and reciprocating under the push of the cylinder. [0003] The 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 electrolyzer has 6 groups of shelling mechanisms, and each group of shelling mechanisms cracks shells once every 60 seconds on average. After several times of shelling, part of the shelling ...

Problems solved by technology

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 then drop it. On average, each electrolyzer consumes one hammer per shift (8 hours per shift), which greatly Increased labor intensity of electrolyzers

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