New process for pole changing operation of aluminum electrolysis cell

Abstract

The invention relates to a novel process for pole-changing operation of an aluminum electrolysis cell, in particular to a production process scheme for pole-changing operation of the aluminum electrolysis cell, which is formulated aiming at an aluminum electrolysis cell anode conductive device formed by arranging a rectangular anode conductive cross beam in a concave groove in the upper part of an anode carbon block. An anode conductive cross beam is directly assembled in a concave groove of an anode carbon block on an anode assembly station, so that high-strength structural connection and tight conductive connection are generated between an anode conductive metal device and the anode carbon block; when the anode changing operation is carried out, the anode scrap conductive device is directly taken out from the aluminum electrolysis cell by using a multifunctional crown block and is placed on an anode scrap processing station outside the electrolysis cell; and then, the sizing covering material device on the upper part of the anode scrap carbon block is directly moved and mounted on the upper part of the anode carbon block of the new anode conductive device by using a hoisting machine tool or a manipulator, and then the new anode conductive device with the sizing thermal insulation layer device is constructed by using a multifunctional crown block and is mounted at the position of the anode changing operation space for edge sealing and seam filling operation, so that the anode changing operation is completed.
