Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolytic cell surface shell material processing, and in particular to an electrolytic aluminum anode shell material recycling and processing system. Background Technology

[0002] During the aluminum electrolysis process, a crust forms on the upper and side surfaces of the anode. This crust, primarily composed of alumina, provides some protection during electrolysis, reducing anode oxidation and burn-off. When the anode is continuously consumed by the electrochemical reaction and needs replacement, the crust is replaced along with the remaining anode. In existing technology, to reuse this crust, after the anode has cooled, the crust needs to be manually or with a scraper separated and crushed. Then, alumina is manually mixed in and stirred thoroughly before reuse. However, due to the uneven particle size of the crushed material and the difficulty in controlling the amount of alumina added, this not only reduces the recycling efficiency of the crust but also affects the electrolysis cell's production efficiency and creates a poor working environment, impacting the health of operators.
