Rotary automatic cleaning device for crust breaking of aluminum electrolysis cell

Abstract

The invention aims to disclose a rotary aluminum electrolysis cell crust breaking automatic cleaning device which comprises a rotatable mechanism, the rotatable mechanism is arranged between a crust breaking hammer head and a fixed earring hole, a cylindrical protection steel plate is arranged on the outer side of the crust breaking hammer head and located on the lower side of a crust breaking air cylinder, and a fixed earring is arranged on the lower side of the cylindrical protection steel plate. A spiral guide rail is arranged on the inner side of the cylindrical protective steel plate, a spiral mantle fiber is arranged on the outer side of the crust breaking hammer head, and the spiral guide rail is matched with the spiral mantle fiber; 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 the 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, convenience and feasibility are achieved, online repair is achieved, and the production efficiency is improved. Time is saved, cost is reduced, and the purpose of the invention is achieved.

Description

technical field [0001] The invention relates to an automatic cleaning device for shelling, in particular to an automatic cleaning device for shelling of a rotary aluminum electrolytic cell. 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...

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
