Automatic cleaning device for vibration crust breaking of aluminum electrolysis cell

Abstract

The invention aims to disclose an aluminum electrolysis cell vibration crust breaking automatic cleaning device which comprises a supporting platform, a metal supporting column and a hollow protection wall, the supporting platform is arranged at the middle upper position in a hollow hammer head rod, the metal supporting column is arranged between the root of the hollow hammer head rod and a hammer head solid part, and the hollow protection wall is arranged in the hollow hammer head rod. The hollow protection walls are arranged on the outer side of the upper portion of the crust breaking hammer head, sliding contact points are correspondingly arranged on the outer side of the hammer head hollow rod and the inner sides of the hollow protection walls, and the sliding contact points on the inner sides of the hollow protection walls are electrically connected through wires. Sliding contact points on the outer side of the hollow rod of the hammer head are electrically connected to the two ends of an oscillator respectively; 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 service life of the shell breaking hammer head and a cylinder of the electrolytic cell is effectively prolonged, and the method is convenient and easy to implement, is easy to implement under the existing conditions, realizes on-line repair, saves time and reduces the cost.

Description

technical field [0001] The invention relates to an automatic cleaning device for shelling, in particular to an automatic cleaning device for vibration shelling of an 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 made of Q235 cast iron with a hollow upper part and a solid bottom part. The hollow part and the solid part are formed into one body 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 sh...

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
