Abstract

A system and method for continuously preparing tungsten powder, the system comprising: an electrolytic cell, a graphite anode basket with holes, an anode feed port, a cathode feed port, a liquid cathode conductive disk, a liquid zinc cathode, a sliding flap, an electrolytic cell support rod, Ball valve collection port, collection crucible, vacuum port, air inlet, exhaust port, oxygen blowing port, and openable discharge door; liquid zinc is used as the cathode to effectively separate the product from the anode slime, and at the same time, the cathode and anode feeding port and sliding The turnover plate and the oxygen blowing port complete the renewal of the electrolytic anode, cathode and molten salt, which can realize the continuous recovery of waste cemented carbide. The invention has the characteristics of high product purity, continuous process and avoiding repeated temperature rise and fall.

Description

[0001] Technical field: [0002] The invention relates to a system and method for continuously preparing tungsten powder. The invention can realize continuous preparation of tungsten powder by using molten salt electrochemical method, supplement raw materials and collect products at working temperature, and belongs to the field of molten salt electrochemistry. [0003] Background technique: [0004] Cemented carbide is a material with high hardness and high bending strength made of refractory metal tungsten carbide and bonding metal by powder metallurgy. It is widely used in machinery manufacturing, mining, transportation, energy exploration, and architectural decoration. and other fields have been widely used. However, refractory metal tungsten and rare metal cobalt are recognized as extremely important strategic elements in the world, and have a very important impact on improving national economy and military competitiveness. Although my country is a country with large tung...
