Embodiment Construction
[0009] exist figure 1 In the cross-sectional view of the continuous anode conduction device for the prebaked carbon block of the aluminum electrolytic cell shown: the anode aluminum bus bar 5 of the electrolytic cell is directly connected to the metal shell (frame) body 1, and the anode current is conducted to the metal shell (frame) through the anode aluminum bus bar 5 The body 1, through the conductive material or the conductive medium 3, reaches the prebaked anode block to realize the function of electrolysis. During operation, the prebaked continuous anode 2 is filled into the metal shell (frame) body 1, and the bottom piece is continuously fully oxidized and consumed to sink during electrolysis, and a new prebaked carbon block 2 is pushed from the upper feeding door 4 , keep replenishing to achieve continuous operation. Wherein the previous piece of prebaked carbon block and the back piece of prebaked carbon block are connected as a whole by conductive material or conduc...
