Electrode and molten salt electrolysis device

Abstract

The invention relates to an electrode and a molten salt electrolysis device. The electrode comprises a rod-shaped part and a supporting part, wherein one end of the rod-shaped part is fixedly connected with the supporting part; the rod-shaped part is positioned in an electrolytic bath while the supporting part is positioned at the outer side of the electrolytic bath and used for sealing an opening of the electrolytic bath during an electrolytic process; and the supporting part is electrically connected with an additional power supply. The electrode is very short, the electrode does not need to pass through the top end of an upper cavity to come into contact with the air in the process that the electrode enters or exits from the electrolytic bath, so that the lifting of the electrode in the upper cavity is realized. Thus, the electrode cannot be corroded, namely, the service life of the electrode is prolonged. The invention provides the molten salt electrolysis device which comprises the electrode and a wiring part. The supporting part is connected with the additional power supply through the wiring part, so that the effects of easy separation and proper movements between the additional power supply and the electrode are realized. According to the molten salt electrolysis device, the lifting of the electrode is realized through a sling structure arranged in a sealing cavity, so that the hidden danger that the air is led in due to the vacuum damage possibly caused by an electrode moving channel is eliminated.

Description

technical field [0001] The invention relates to the field of metallurgy and chemical industry, and particularly designs an electrode and a molten salt electrolysis device applied to a molten salt electrolysis process. Background technique [0002] Molten salt electrolysis is a process that uses molten salt as a medium to electrochemically purify or separate crude metals or alloys by using the potential difference during the metal reduction process. In the molten salt electrolysis process, electrodes are necessary components. Among them, one end of the electrode is used to connect with an external power supply; the other end of the electrode needs to be placed in the molten electrolytic medium in the electrolysis tank before the electrolysis starts. During the electrolysis process, the end of the electrode protruding into the electrolytic cell gradually gathers solid electrolytic products, such as the process of producing high-purity titanium by molten salt electrolysis, tit...

AI Technical Summary

Problems solved by technology

[0004] It has been found in practice that when the above-mentioned electrode device is used in an electrolysis process that needs to be kept in a vacuum or a protective gas protection state, the purity of the solid electrolysis product finally obtained is relatively low

Moreover, after using the existing electrode for a period of time, a layer of impurities will adhere to the surface of the electrode 10 in the upper chamber 11, which blocks the movement of the electrode along the central axis of the upper chamber 11.
