Inert anode aluminum electrolytic cell with vertical structure

An inert anode aluminum electrolytic cell with a vertical structure, comprising:

• an electrolytic cell shell, provided with three insulating layers therein, wherein the three insulating layers comprise a first insulating layer, a second insulating layer and a third insulating layer;
• the first insulating layer and the second insulating layer have both fixed structures;
• the first insulating layer is opened with a groove thereon, and an opening of the groove is upward;
• and the third insulating layer has a replaceable and movable structure;
• a heating device, disposed in the groove on the first insulating layer, and configured to adjust a temperature of the electrolytic cell;
• a graphite base, disposed at a bottom of an inner cavity of the electrolytic cell shell, and opened with a mounting slot at a bottom thereof, wherein side walls of the second insulation layer and the bottom of the graphite base each are attached to the third insulating layer to form a furnace of the electrolytic cell, and the furnace of the electrolytic cell is configured to contain an electrolyte melt and an aluminum liquid;
• and
• cathodes, being in a shape of a vertical plate, vertically mounted in the mounting slot, and threadedly connected to the graphite base through graphite bolts, wherein contact surfaces among the graphite base, the graphite bolts and the cathodes are all covered with a cathode paste;
• one side of the cathodes is provided with anodes, and the anodes and cathodes are staggered;
• the cathodes are suspended above the electrolytic cell shell by connecting to a guide rod;
• a current of the anodes passes through the guide rod and enters an interior of the electrolytic cell shell from a top of the electrolytic cell;
• and a current of the cathodes passes through the graphite base and is led out of the electrolytic cell shell through a metal electric rod connected to the graphite base.
