Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolysis, in particular to a multifunctional shell-breaking cylinder for an electrolytic cell. Background Art

[0002] Shelling cylinders are crucial equipment used in the aluminum electrolysis production process, primarily for pole changing, shelling, material compaction, and electrolytic cell maintenance. In aluminum electrolysis production, shelling cylinders operate in extremely harsh environments, requiring them to operate in high-temperature, highly corrosive environments. Especially during electrolytic cell maintenance, material loss from the shaft ends occurs due to long-term friction and wear with the hard shell surface, abrasive wear from the electrolytic raw materials, and high-temperature corrosion from the electrolyte molten salt. Ultimately, the shaft ends shrink, resulting in a "pencil-tip" shape. The shaft head area is small, making it difficult to compact the material during material pressing in the damaged cell. Compaction takes a long time, resulting in poor repair results and increased labor intensity. Utility Model Content

[0003] In view of the technical problems existing in the background technology, the purpose of the utility model is to provide a multifunctional shell-breaking cylinder for an electrolytic cell, which is provided with a replaceable hammer head structure, which is not only convenient for protecting the shaft end, but also convenient for compacting the material in the damaged cell.
