The invention discloses an aluminum electrolysis cell pole changing and crust breaking device and application thereof. The aluminum electrolysis cell pole changing and crust breaking device is mainly composed of a cutting machine, a cutting machine seat, an extensible device and a support, the extensible device is hinged in the middle lower section of the support, the other end of the extensible device is hinged to the cutting machine seat, and the cutting machine is connected on the cutting machine seat. The cutting machine is used to replace a hammer crust-breaking device, accurate cutting of covering material crust is realized, crust fragments generated by crust breaking are reduced greatly, material blocks and material residue in electrolyte are reduced, operation time, of operators, for cleaning anode pit material blocks and material slag at high temperature is shortened, interference, on an electrolysis cell, caused by anode replacement is reduced, and stable running of the electrolysis cell is promoted.
Description
technical field [0001] The invention relates to a shelling device, in particular to a shelling device for changing poles of an aluminum electrolytic cell. The invention also relates to the application of the pole-changing shell-breaking device for an aluminum electrolytic cell. Background technique [0002] The traditional Hall-Héroult aluminum electrolysis process has always been the only method for industrial aluminum smelting, and the aluminum electrolytic cell is its core equipment. In the production of aluminum electrolysis, the service life of each group of prebaked anodes is about 28-36 days. Therefore, when the life of the prebaked anodes ends, it is necessary to take out the remaining anodes and reinstall new anodes. This process is called anode replacement, referred to as replacement. pole. Since the periphery and sides of the anode are covered with hard Al 2 o 3 Therefore, before changing the pole, the crust needs to be opened to remove the butt pole and insta...
