Description

technical field [0001] The invention relates to the field of aluminum electrolysis, and more specifically, relates to an anode replacement system for aluminum electrolysis production. Background technique [0002] In the production process of aluminum electrolysis, the anode carbon block will be continuously consumed as the electrolysis progresses, and it needs to be replaced when it is consumed to a certain extent. The anode that is worn out and needs to be replaced is called the old pole, also called the residual pole, and the replaced anode is called the new pole. According to the production process requirements of aluminum electrolysis, the bottom palm plane of the new pole and the bottom palm plane of the residual pole should be on the same horizontal plane in the electrolytic cell to achieve current balance. Therefore, when the anode is replaced, it is necessary to measure the height of the old and new anodes, and this process requires the assistance of an aluminum el...
