A FEEDING APPARATUS FOR A LARGE AMPERAGE PREBAKED ANODE ALUMINUM ELECTROLYTIC CELL

摘要

: The present invention discloses a superstructure configuration of large amperage prebaked anode aluminum electrolytic cell, comprising a pipeline network for controlling the compressed air for crust breaking and feeding, crust breaking device, feeding device, alumina hopper, and aluminium fluoride hopper, characterized in that each feeding point corresponds to the crust breaking device and the feeding device, in that the pipeline network for controlling the compressed air for crust breaking and feeding is respectively connected to the crust breaking device and the feeding device, and in that the feeding device is mounted on the alumina hopper and the aluminium fluoride hopper. The present invention changes the original configuration having four feeding points into a configuration having five feeding points such that the superstructure of the electrolytic cell is more compactly designed, space is more reasonably utilized, wear of wearing parts is reduced, cost is cut, and meanwhile stability of electrolytic production is improved.
