Electrolytic Cell Charge Storage Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for changing anode assemblies in aluminum smelters result in prolonged opening times of electrolytic cells, leading to increased thermal losses and gas leaks, as well as cluttered operating aisles and safety hazards due to the need for extensive storage of equipment outside the intervention zone.
Innovation Solution
A charge storage device is positioned above the electrolytic cell, utilizing support means that allow for stable storage of new and worn anode assemblies and crust collection devices, reducing the need for extensive aisle space and enabling closer proximity to the intervention area, thus minimizing the duration the access window is open.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If anode assemblies and equipment are stored in the operating aisle near the electrolytic cell, then the access window can remain open for a shorter duration, but the operating aisle becomes cluttered and requires widening, increasing structural cost and hindering vehicle and personnel circulation
Solution Approach 1:
The patent introduces a vertical storage dimension by positioning the storage device above the electrolytic cell using support means, transferring storage space from the horizontal operating aisle to the vertical space above the cell, thereby resolving the conflict between quick access and aisle clearance
2Ease of operation
If the access window is kept open for an extended period to allow equipment storage and anode assembly operations, then equipment can be stored and operated, but thermal losses and gas leaks increase
Solution Approach 1:
The storage device is pre-positioned above the electrolytic cell with support means ready to receive anode assemblies and equipment, allowing all necessary items to be stored before the access window is opened, enabling the window to remain closed during storage operations and only opened briefly for the actual anode assembly change
Solution Approach 2:
The storage device acts as an intermediary between the operating aisle and the electrolytic cell intervention zone, receiving and holding anode assemblies and equipment above the cell, thereby eliminating the need to store items in the operating aisle and reducing the time the access window must remain open
3Quantity of substance
If storage space is provided in the operating aisle, then equipment can be temporarily stored, but visibility of personnel and vehicle operators is obscured, requiring additional security measures
Solution Approach 1:
By moving storage from the horizontal operating aisle to the vertical space above the electrolytic cell, the patent eliminates visibility obstruction in the operating aisle while maintaining adequate storage capacity for anode assemblies and equipment
