Abstract: The present disclosure relates to a field of aluminum smelting, and in particular to an inert anode aluminum electrolytic cell with a vertical structure, which includes: an electrolytic cell shell (1), a heating device (5) and a graphite base (13). The electrolytic cell shell (1) is provided with three insulating layers therein. The heating device (5) is disposed in the groove on the first insulating layer (4) The graphite base (13) is disposed at a bottom of an inner cavity of the electrolytic cell shell (1). A bottom of the graphite base (13) is opened with a mounting slot. The cathode is vertically mounted in the installation slot. The anode (17) is arranged in a staggered manner with the cathodes (16) and is suspended above the electrolytic cell shell (1) by connecting to a guide rod (11).

Abstract: The invention discloses a direct-current shunt preheating start method for an inert electrode aluminum electrolysis cell, comprising: (1) forming multiple groups of direct-current shunt elements by using conductors with preset resistance values and geometric sizes; (2) laying in a hearth of the electrolysis cell electrical heating element groups of the same number as/a different number from electrode groups; (3) drying the hearth, smelting electrolyte and establishing a thermal balance and a hearth inner profile by using the electrical heating element groups according to a set heating curve or set steps; (4) changing the number of groups/a series or parallel connection state of the direct-current shunt elements; and (5) gradually replacing inert electrodes and gradually adjusting the number of the groups of/the series or parallel connection state of the shunt elements.
