CATHODE DEVICE OF ALUMINUM CELL Russian patent published in 2008 - IPC C25C3/08 

FIELD: production of aluminum by electrolysis, namely design of cathode device of aluminum cell.

SUBSTANCE: apparatus includes metallic bath with bottom and reinforcing members embracing walls and bottom of bath and forming cathode jacket. Inside cathode jacket there are lining and cathode blocks with cathode rods forming cathode of cell. To lengthwise and end walls of metallic bath between reinforcing members plate-type ribs made of material with high heat conductance are secured. Surface area of one plate-type rib is in range 0.03 - 0.3 m². Plate-type ribs are secured to metallic bath by means of bimetallic adapters such as aluminum-steel or copper-steel with use of explosion welding. Steel part of bimetallic adapter is welded to walls of metallic bath and plate type ribs made of aluminum or aluminum alloy or of copper or copper alloy are welded to aluminum or copper part respectively. In upper part of reinforcing members rotary flaps are mounted for controlling heat radiation from bath walls. Between reinforcing members there is device such as fan or blower for positively cooling plate -type ribs.

EFFECT: intensified process of electrolytic production of aluminum due to controlled heat radiation, stable manufacturing process, increased useful life period of aluminum cell.
