DEVICE AND METHOD FOR CONTINUOUSLY PREPARING HIGH-PURITY METAL TITANIUM POWDER BY ELECTROLYSIS

摘要

Disclosed in the present invention are a device and method for continuously preparing high-purity metal titanium powder by electrolysis. The method of the present invention comprises: electrolyzing a titanium-containing conductive ceramic anode and a rotary cathode in a molten salt electrolyzer; the rotary cathode continuously transferring metal titanium powder deposited on a cathode surface above molten sa a discharge scraper scraping and then collecting the metal titanium power, and then recovering molten salt by filtration; cooling the separated metal titanium powder and then using deoxidized and deionized water to wash same; and finally, vacuum drying to obtain prepared metal titanium powder. The present device comprises a molten salt electrolysis device, a metal titanium powder continuous collection device, a filtration device, a washing device and a vacuum drying device. The present invention achieves the continuous preparation of high-purity metal titanium powder, may adjust the average particle size of the prepared metal titanium powder online, and has high production efficiency, a simple operation and high product purity.
