Segmented Contact Bar for Electrolytic Cell
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional contact bars connecting multiple anodes and cathodes in electrolytic cells are prone to causing widespread short circuits, leading to increased temperatures and potential deformation of insulating capping boards, resulting in metal impurities and defects in refined products.
Innovation Solution
A segmented contact bar with conductive pieces and insulating core segments, allowing only specific anodes and cathodes to be connected, isolating short circuits to individual segments rather than propagating across all electrodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional contact bar connects all anodes and cathodes along the full length of the capping board, then electrical connection between adjacent cells is achieved, but short circuits can propagate across all electrodes causing widespread temperature increase and potential deformation of the capping board
Solution Approach 1:
The contact bar is divided into multiple isolated contact segments along its length, with insulating barriers between them. Each segment independently contacts specific anodes and cathodes at different positions along the capping board. This segmentation prevents short circuit propagation from affecting all electrodes, as a fault in one segment remains isolated to that local area only.
2Productivity
If the contact bar extends over the full length of the capping board to connect all electrodes, then complete electrical distribution is achieved, but the risk of temperature increase and deformation affecting the entire system increases

AI summary
Disclosed is a segmented contact bar for use boarding an electrolytic cell. The segmented contact bar has contact pieces made of electrically conductive material and being in spaced apart relation along the capping board, each of the contact pieces defining a segment for supporting and electrically connecting an anode and a cathode in the electrolytic cell. The segmented contact bar also has connection members including an insulating material and provided in between pairs of adjacent segments for providing insulating interconnection of the segments. There is also an electrolytic refining apparatus including adjacent electrolytic cells; a capping board positioned on the adjacent electrolytic cells; anodes and cathodes extending in spaced apart alternate positions into the each of the adjacent electrolytic cells along the capping boards; and a segmented contact bar.
