Description

Technical Field

[0001] The utility model belongs to the technical field of electrochemistry metallurgy, and particularly relates to an electrolysis device capable of observing the consumption amount of molten salt in real time. Background Art

[0002] During the electrolysis process, molten salt serves as a conductive medium, and the amount thereof can affect the current density, reaction rate, and product selectivity, etc. In a fixed electrolytic cell, if the amount of molten salt is small, the ion concentration in the electrolyte will decrease, which may lead to a decrease in the current density because the low ion concentration limits the charge transfer efficiency. Conversely, appropriately increasing the amount of molten salt can increase the ion concentration in the electrolyte, thereby possibly allowing a higher current density for electrolysis.

[0003] During the electrolysis process, the electrolyte will be consumed by volatilization over time. A part of it solidifies above the electrolytic cell, and another part enters the tail gas system with the gas flow; as the volume of the electrolyte decreases, the structure, morphology, and purity of the deposited product will be significantly affected.

The rotating handle 51 drives the strip-shaped scraper 52 to rotate, and the rotating strip-shaped scraper 52 scrapes off the solidified molten salt on the lens, thereby restoring the observation line of sight.
