Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary equipment for aluminum electrolysis cells, and in particular to an aluminum electrolysis backflow trolley. Background Technology
[0002] In the aluminum electrolysis production process, in order to meet process requirements, it is often necessary to adjust the electrolyte level in the electrolytic cell through a backfilling operation. The backfilling operation is to transfer the electrolyte from the electrolytic cell with a high electrolyte level to the electrolytic cell with a low electrolyte level.
[0003] During the transfer operation, electrolytes are typically transferred manually by carrying buckets. Because electrolytes are dense and have a high temperature, they easily solidify when the temperature drops, thus requiring a certain speed for transfer. Therefore, currently, trolleys are often used to transfer the buckets containing electrolytes. However, when workers push the trolley to transport the buckets to the target electrolytic cell, they still need to first remove the buckets from the trolley before pouring the electrolytes into the target electrolytic cell.
[0004] However, during the above process, staff inevitably come into contact with the tank containing high-temperature electrolytes. Due to the large weight of the electrolytes in the tank, improper handling during pouring can easily cause electrolytes to splash or spill out of the tank, which may not only burn staff but also burn clothing and cause a fire, posing a significant safety hazard.
