Description

Technical Field

[0001] The utility model relates to the field of aluminum electrolysis, in particular to an integrated aluminum electrolytic cell busbar hoist booster system. Background Art

[0002] When the aluminum electrolytic cell is in normal production and operation, the current passes through the electrolytic cell column busbar, balance busbar, anode guide rod, anode carbon block, electrolyte / aluminum liquid, cathode, cathode busbar, and then supplies to the next electrolytic cell, so that each electrolytic cell is connected in series. With the periodic consumption of anode carbon blocks during the production process of the electrolytic cell, the electrolytic cell busbar will drop accordingly. Therefore, the periodic adjustment of the electrolytic cell busbar, that is, the busbar lifting operation, has become a key operation in the daily production process.
