Description

Technical Field

[0002] Molten salt electrolysis is an important metal smelting method widely used in the production of metals such as aluminum, magnesium, and lithium. Its principle is to use molten salt as an electrolyte, which, under the influence of direct current, reduces metal ions to elemental metals. However, traditional molten salt electrolysis furnaces have the following technical problems:

[0003] Intermittent operation is inefficient: Traditional molten salt electrolysis furnaces operate intermittently. After electrolysis for a period of time, electrolysis must be stopped, cathode products removed, and new raw materials added, resulting in low production efficiency.

[0004] High energy consumption: Frequent start-up and shutdown of the electrolytic cell leads to energy waste and increases production costs.

[0005] Unstable product quality: Intermittent operation can easily cause fluctuations in parameters such as temperature and concentration in the electrolytic cell, affecting product quality.

[0006] Manual operation is complex: The material handling and feeding processes require manual intervention, which increases the complexity of the operation and the intensity of labor. Utility Model Content
