Embodiment Construction
[0040] The method of the present invention only needs to set up a set of production line system, and only a set of catenary is arranged in the production line system, and a system for assembling single and double anodes of aluminum electrolytic cell is set under the catenary. Such as image 3 As shown, the working areas included in the system are loading and unloading area, electrolyte cleaning area, electrode residue shot blasting area, electrode residue pressure stripping area, phosphorus iron ring pressure stripping area, steel claw shot blasting area, and straightening area according to the order of the anode working path. area, guide rod cleaning area, graphite dipping area, steel claw drying area and pouring area. The working area is divided into two types: multi-station area and single-station area. Anodes with butts are hung under the catenary and run to each work area in turn for assembly work. Among them, the electrolyte cleaning area, the residual electrode shot b...

A method for assembling single and double anodes of aluminum cells under the same suspension chain is characterized in that a system for assembling single and double anodes of aluminum cells under the same suspension chain is arranged; the system is internally provided with a photoelectric switch and an actuating mechanism; the photoelectric switch can identify the single and double anodes on line; the assembling process comprises the followings: removing electrolyte on the surfaces of residual single and double anodes, shotblasting impurities on the surfaces of the residual anodes, pressure-disengaging residual anode rods from anode rods, pressure-disengaging phosphoric pigiron rings, shotblasting the surfaces of steel studs of the single and double anodes, straightening the rods and steel studs of the single and double anodes, flushing the rods of the single and double anodes, dipping graphite on the steel studs of the single and double anodes and pouring the rods of the single and double anodes. The method reduces the additional cost, caused by addition of another set of system, of investment on professional devices such as processing devices, ventilation devices, power devices and the like, especially investment on floor areas of plants and civil engineering, etc.
Description
Technical field: [0001] The invention belongs to the aluminum electrolysis anode assembly technology, in particular to a method for assembling single and double anodes of an aluminum electrolysis cell under the same catenary. The method only needs to set up a production line system, in which only a set of suspension conveyors (short for catenary chain) is arranged, and the production line system can simultaneously complete the assembly and production of single and double anodes. Background technique: [0002] At present, the aluminum industry is developing rapidly, and a large number of new or rebuilt projects of electrolytic aluminum have emerged, most of which choose large prebaked electrolytic cells. These prebaked electrolytic cells need prebaked anodes (referred to as anodes) to complete the production of molten aluminum. The anode is a consumable, and the anode in the electrolytic cell needs to be replaced regularly to ensure the continuous and normal operation of the...
