Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary devices for sponge titanium production, and in particular relates to an automatic cleaning device for a magnesium electrolytic cell. Background Art

[0002] Titanium and titanium alloys are widely used in aerospace, medical, chemical, automotive, energy and shipbuilding fields due to their low density, high specific strength, good corrosion resistance, excellent heat resistance and non-magnetic properties. Sponge titanium production is the basic link in the production of titanium materials, titanium powder and other titanium structural parts. The production process of sponge titanium includes chlorination refining, reduction distillation, magnesium electrolysis, tail gas treatment, crushing and other processes, among which reduction distillation is the core process of sponge titanium production. Currently, large-scale titanium smelting companies at home and abroad mostly use magnesium reduction distillation to prepare sponge titanium, which realizes the closed-loop circulation of raw materials Mg-Cl2-MgCl2.

[0003] In the production of titanium sponge, in order to realize the cycle of magnesium and chlorine, it is necessary to build a magnesium electrolysis process. The magnesium chloride produced in the reduction process is used as the electrolysis raw material, and the magnesium produced by electrolysis is used to reduce the production of titanium sponge. Among them, the magnesium electrolytic cell is an important equipment for the production of titanium sponge by magnesium electrolysis. During use, due to the high temperature and the corrosion of magnesium chloride, it is easy to cause the cathode bed, cathode, anode, partition wall and side wall inside the magnesium electrolytic cell to be severely corroded after a period of time, which reduces the electrolysis efficiency of the magnesium electrolytic cell. The masonry materials and accessories damaged by internal corrosion need to be removed and rebuilt and installed. However, during the demolition process, due to the limited structural environment of the magnesium electrolysis plant, large-scale mechanical equipment cannot enter the plant, and the manual cleaning and demolition speed is slow, which requires a lot of manpower and time, and the demolition efficiency is low, which seriously affects the maintenance progress; at the same time, the working environment in the magnesium electrolytic cell is poor, and a large amount of dust will be generated during cleaning and demolition, which is harmful to human health.
