Embodiment Construction

[0013] The method of repairing the side wall of the aluminum electrolytic cell without stopping production is to determine the repair area after finding out the damaged part of the aluminum electrolytic cell, and use a flame cutting device to cut the inner edge plate of the corresponding part of the damaged aluminum electrolytic cell side wall; then open the aluminum electrolytic cell Fill the aluminum oxide surface shell on the side wall of the tank to be repaired, and fill the liquid area between the damaged side wall and the anode of the aluminum electrolytic cell while tamping the electrolyte block and surface shell block materials until the entire damaged side wall is tightly sealed and filled. The area between the anodes forms an isolation cofferdam to block the electrolyte aluminum liquid; the electrolyte block is obtained from the electrolyte solution taken from the aluminum electrolytic cell in production and operation after condensation and crushing, and the compositio...

Abstract

A technology for repairing the side wall of aluminium electrolyzer without stopping production includes cutting open the internal edge plate at the position where the side wall is damaged, opening the alumina shell, filling and compacting the isolating dam between said damaged side wall and anode, removing the residual substance from said side wall, mounting new side wall, welding the internal edge plate, blocking by cryolite and alumina powder, and natural calcining. Its advantages are high speed and low cost.

Description

technical field [0001] The invention relates to a method for repairing the side wall of an aluminum electrolytic cell without stopping production, and is suitable for occasions where the side wall of the aluminum electrolytic cell is damaged. Background technique [0002] Damage to the side wall of the aluminum electrolytic cell is one of the main forms of damage to the aluminum electrolytic cell. Damage to the side wall of the aluminum electrolytic cell will increase the consumption of production materials and labor intensity, greatly reduce the electrolysis efficiency, and seriously threaten the safe production and operation of the aluminum electrolytic cell. For the damage of the side wall of the aluminum electrolytic cell, the aluminum electrolytic plant generally adopts three methods to deal with it. One is the condensed electrolyte method, which commonly uses materials such as electrolyte blocks to fill the damaged part of the side wall of the aluminum electrolytic cel...
