Corner insert for edge strips used with modified electrodes for electrolytic processes

Abstract

A corner insert for edge strips used with modified electrodes for electrolytic processes. An electrode that is at least partially submerged in an electrolyte is protected by edge strips to prevent depositions and metallic bridges. The edge strips are typically mitered to abut one another at the corners of the electrode and it is difficult to seal this junction. One solution is to remove the corners of the electrode, provide non-mitered edge strips, and close the gap at the corner with an insert adapted to seal to the additional edges of the electrode created by removing the comers. Another solution is to provide a corner insert having one or more anchors for anchoring the corner insert to the electrode and to respective adjacent edge strips, the corner insert sealing against the edge strips and against opposite sides of the electrode whether or not the corner portion has been removed. Yet another solution is to omit an edge strip at the bottom edge of the electrode, and provide an edge strip insert having an anchor for anchoring the edge strip insert to the electrode and to an edge strip which receives the anchor, the edge strip insert for sealingly seating against the edge strip and against opposite sides of the electrode whether or not the corner portion has been removed.
