Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic production, in particular to an electrolytic cell used for electrolyzing metallic manganese. Background Art

[0002] Metallic manganese is an important industrial raw material, widely used in metallurgy, chemical industry, light industry, electronic materials and other industries, among which the most important application is the steel metallurgical industry. In the steel industry, the amount of manganese used is second only to iron. China has developed into the largest producer and consumer of electrolytic manganese. At present, metallic manganese is mainly obtained by acid leaching manganese ore to obtain manganese salt, which is then sent to the electrolytic cell for electrolysis to precipitate the elemental metal. Usually, manganese ore is used to prepare an electrolyte, which is then passed into the electrolytic cell and the cathode plate is used to precipitate manganese metal.

[0003] During the electrolysis process, the distance that the anions and cations in the electrolytic cell move toward the anode and cathode plates directly affects the size of the resistance in the cell, which in turn affects the energy consumption of electrolytic production. Once a traditional electrolytic cell is manufactured, the distance between the anode and cathode plates on it is fixed, and it is impossible to flexibly adjust the distance according to the concentration of the electrolyte, resulting in high energy consumption in electrolytic production.

[0011] To further optimize the technical solution, a first sealing ring is provided around the end surface of the convex frame to seal the contact surface of the anode liquid area at the lower part of two adjacent cathode frames to prevent leakage of the anode liquid area.
