Description
Technical Field
The utility model relates to the technical field of aluminum electrolysis production, in particular to a special device for repairing an anode guide rod steel claw group of an aluminum electrolysis cell.
Background
The anode guide rod steel claw group in the electrolytic aluminum industry in China is formed by colored welding of an aluminum guide rod and an aluminum surface of a composite block, explosive welding of the composite block steel and aluminum, black welding of the composite block and a steel claw, pouring of the steel claw group and phosphorus pig iron of an anode carbon block and the like which are sequentially combined. For poor combination quality of the anode guide rod group in electrolytic production, the guide rod group consumes 9 degrees of electric energy every day when the pressure drop rises by 1 mV. Therefore, all aluminum electrolysis enterprises pay great attention to the repair work of the anode guide rod steel claw group. Taking a certain electrolysis enterprise as an example, the original aluminum can produce 57 million tons, the anode guide rod steel claw groups are 19000 groups in total, and the annual maintenance amount reaches more than 20000 groups.
The traditional repair process of each electrolytic aluminum production enterprise comprises the following steps: (1) fixing a guide rod steel claw group at the gravity center part of an aluminum guide rod and a steel claw by a lifting appliance from a vertical state, turning to a horizontal state by a crane for gas cutting to scrap claw heads, such as eight-claw or six-claw steel claws, and turning to perform gas cutting if the claw heads to be replaced are arranged on both sides; (2) the guide rod steel claw group is hoisted to the vertical state from the horizontal state to be butted and spot-welded with a new claw head on the worktable; (3) in order to ensure the welding quality, a flat welding mode is adopted, the guide rod steel claw group needs to be lifted from a vertical state and turned over to a horizontal state for welding, and four-side welding needs to be carried out by turning over three times when one side is welded. The process has the disadvantages of long hoisting process, complex operation, long service life of hoisting equipment, high labor intensity of personnel, frequent use of various hoists and fixing devices and great potential safety hazard in steel claw repair. The whole repair process has the disadvantages of low efficiency, large power consumption, high repair cost and the like.
