Embodiment Construction
[0009] exist figure 1 In the cross-sectional view of the conduction mode of the carbon continuous anode of the new aluminum electrolytic cell shown: the anode conductive aluminum bus bar 2 of the electrolytic cell is directly connected to the metal shell 1, and the anode current is conducted to the metal shell 1 through the anode conductive aluminum bus bar 2. Conductor medium 5, to the anode cone 6 to realize the function of electrolysis. During operation, the carbon anode paste block (or grain) 3 is filled into the shell from the side or upper part of the continuous anode metal shell 1, and slowly falls down due to the consumption of the lower anode cone 6, and falls to the temperature in the box. When it reaches the position of 400 to 600 degrees, it will be melted into a fluid paste layer, that is, the anode paste fluid 4, and then becomes the anode cone 6 as the temperature rises downward, and conducts work through the good conductor interlayer 5. Wherein, the good elect...

The invention discloses a novel electric conduction mode of a carbon continuous anode of an aluminum electrolytic cell, and is used in the technical field of aluminum electrolysis cells. The electricconduction mode comprises a continuous anode metal shell 1, a conductive aluminum bus 2, a carbon anode paste block (or particle) 3, an anode paste fluid 4, a good conductor dielectric layer 5 and ananode cone 6. The device has the following advantages that 1, the continuous anode carbon material can be a large paste geometry; 2, the current is conducted directly to the continuous anode metal shell through the anode conductive aluminum bus, and then is conducted to the good conductor dielectric layer, and the current is conducted through the good conductive dielectric layer to the anode cone(or carbon electrode); 3, the good conductor dielectric layer may be consumed as the anode cone is consumed, 4, the good conductor dielectric layer is tightly attached to the continuous anode metal shell and the anode cone.
Description
technical field [0001] The invention belongs to the technical field of aluminum electrolytic cells. Background technique [0002] The prebaked anode of the existing aluminum electrolytic cell needs to replace the anode block, there is a residual electrode, the process is complicated, and the cost is high.
