Unattended production method for aluminum electrolytic prebaked anode replacement and insulation material maintenance

Abstract

The invention discloses an aluminum electrolysis prebaked anode replacement and heat insulation material maintenance unattended operation production method. Before prebaked anode replacement, aluminumoxide attached to the upper surface of an anode scrap is firstly cleaned out of a tank; edge opening treatment is performed on the periphery of the anode scrap; the anode is hung out of an electrolysis tank; before a new prebaked anode enters the tank, anti-oxidation paint is sprayed and coated at the prebaked anode surface; after a heat insulation pad block is placed at the upper surface of thenew prebaked anode, a maintenance-free on-electrode heat insulation plate is placed at the prebaked anode surface; the new anode is placed into the electrolysis tank by a multifunctional overhead crane; a clamp device is tightly fastened; after the new anode placement, the electrolysis tank edge part is placed at the edge part in a way of approaching to the new anode by using a maintenance-free edge part heat insulation block; electrolysis tank anode medium seams are filled with a maintenance-free medium seal heat insulation block; the positions of fire holes and discharging openings are reserved; when a new round of anodes need to be replaced, only the edge heat insulation block needs to be moved away; the anode scrap is hung out; the on-electrode heat insulation plate is replaced on thenew anode. The active and effective effects are achieved for realizing the unattended operation full automatic operation.

Description

Technical field: [0001] The invention relates to an unattended production method for aluminum electrolytic prebaked anode replacement and insulation material maintenance, in particular to a normal anode replacement and insulation material maintenance work on the electrolytic cell pole in the aluminum electrolysis production process, which belongs to aluminum electrolysis production Maintenance technical field. Background technique: [0002] Aluminum electrolysis production is a continuous production. The development of aluminum electrolysis production has not yet broken through the fully automated and mechanized operation mode. At present, it still remains at the level of a large number of manual operations, especially the electrolysis work and anode replacement. Do it manually. The electrolytic cell is a high-temperature melting furnace with a strong magnetic field and high temperature, especially during the anode replacement process. When the anode residue is lifted out o...
