The invention relates to an aluminum electrolysis cell efficient crust breaking device and crust breaking method.The crust breaking device comprises a hammer head and a cylinder body connecting body, a center hole III is formed in the cylinder body connecting body, the hammer head is slidably connected into the hammer head center hole III, the hammer head comprises a cylindrical part and a hammer head part, the hammer head part is arranged at the lower end of the cylindrical part, and the cylindrical part is slidably connected into the center hole III; the lower end of the cylinder body connecting body is rotatably connected with a lower rotating body which is provided with a center hole I. The cylindrical part is slidably connected in the center hole I. The outer wall of the cylindrical part is provided with a long groove, the inner wall of the center hole I is provided with a pin shaft groove, a pin shaft is connected between the long groove and the pin shaft groove, the long groove is slidably connected to the pin shaft, and the upper end of the cylinder body connecting body is connected to the hydraulic cylinder. Pistons of the hydraulic cylinders are connected with the top face of the cylindrical part. The piston of the hydraulic cylinder can drive the hammer head to beat the shell up and down, and beating in the vertical direction is achieved. The multi-directional crust breaking device has the advantages of being simple in structure, practical, convenient to operate and capable of achieving multi-directional crust breaking and effectively improving the crust breaking efficiency.
Description
technical field [0001] The invention relates to the technical field of aluminum electrolysis, in particular to a high-efficiency shelling device and a shelling method for an aluminum electrolytic cell. Background technique [0002] Aluminum electrolytic cells are mainly used in the production of aluminum smelting plants, and the anodes are made of carbon materials. During the production process, the surface of the molten aluminum salt electrolytic solution will form crusts, and the crusts will surround the anodes. Since the anodes need to be replaced frequently, the replacement The crust needs to be broken before, and the anode can be replaced and the residue can be cleaned after the crust is broken; the current breaking method is that the hydraulic cylinder drives the cylindrical hammer head to move up and down, and the steel claw is lifted out to lift out the square liquid surface of the required size . Existing shelling hammer head that uses is cylindrical, is directly c...
