Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum electrolysis production, in particular to a residual electrode fixing device for aluminum electrolysis production. Background Art

[0002] Carbon anodes are called the "heart" of aluminum electrolytic cells. They are continuously consumed in aluminum electrolysis production and need to be replaced regularly. The old anodes that have been consumed to a certain extent are pulled out and replaced with new anodes. Anode replacement involves multiple operations, among which the operation of pulling out the anode residues is generally to use the multifunctional unit anode grabber to grab the anode guide rod, pull the anode residue out of the electrolytic cell, lift it to a position higher than the cell cover plate, and then move it along the inter-cell channel to the outside of the cell and place it in the anode residue tray.

[0003] In the production of modern large-scale aluminum electrolytic cells, most production lines use a guide rod to connect an anode carbon block to form an anode, and the pole replacement operation is generally performed by replacing two anodes at the same time as a group. First, the shell surface of the alumina is broken with the shell breaker on the multifunctional unit, and then the residual pole is replaced. During the transportation of the residual pole, the broken shell surface block between the two anodes often falls due to the shaking of the guide rod. The falling high-temperature material blocks can easily cause personal injuries, short-circuit insulation burnout, etc., which poses a great safety risk. At the same time, it will also damage the tank cover plate, style plate, floor, etc., resulting in increased maintenance costs and increased labor for material cleaning. Utility Model Content
