Description

Technical Field

[0001] The utility model relates to the technical field of steam cleaning equipment, in particular to a cathode automatic adjustment device for a rare earth electrolytic furnace. Background Art

[0002] At present, the rare earth molten salt electrolysis process is the main method for the production and preparation of rare earth metals. The electrolytic cell is the main equipment in this process, and its structure directly affects the quality of rare earth metal products, work efficiency and production cost. When the rare earth oxide is melted in molten salt, the melting temperature in the electrolysis equipment is above 1000°C. Maintaining a balanced and stable melting temperature during the electrolysis process is one of the prerequisites for the normal operation of the electrolysis process.

[0003] Existing electrolytic furnaces usually place a molybdenum pot for collecting rare earth metals at the bottom of the furnace, and graphite anodes are installed around the furnace. A tungsten-molybdenum alloy rod is inserted in the middle of the furnace as a cathode. The furnace is filled with molten salt. Under the action of the inter-electrode electric field between the cathode and the anode, the molten salt acts as a resistor to generate heat and becomes molten, while maintaining the temperature required for the electrolysis process.

[0004] Among them, the tungsten rod as the cathode guides the current to flow through the electrolyte during the electrolysis process. The current enters the electrolytic cell through the tungsten rod, thereby starting the electrolysis process. At the same time, during the electrolysis process, the tungsten rod as the cathode will be gradually consumed. This consumption will cause the distance between the cathode and the anode to change, thereby affecting the cell voltage and energy consumption of the electrolytic cell. Therefore, a device that can adjust the cathode of the electrolytic furnace is needed. Utility Model Content
