Device for metallizing uranium oxide and recovering uranium

A device for metallizing uranium oxide and recovering uranium, comprising:

• a heating furnace including at least one first heating unit for allowing the reaction vessel to be maintained at a high temperature;
• a reactor including a reaction vessel having an discharging valve hole located at a center of a bottom thereof and a conical bottom tapered to the discharging valve hole, a sealing lid for sealing the reaction vessel airtight, an argon gas inlet port for feeding argon gas into the reactor ther, and an argon gas outlet port for venting argon gas from the reactor therethrough;
• a valve assembly for controlling the discharging valve hole of the reaction vessel;
• a plurality of agitators for uniformly mixing a mixture in the reactor;
• a lithium metal feeder including a second heating unit and removably installed through the sealing lid to feed molten lithium metal into the reactor;
• a cooling jacket set in the sealing lid to allow compressed air to continuously flow therethrough to intercept heat from the reactor;
• a porous filter located under the reactor in the heating furnace to filter a resulting product discharged from the reactor;
• and
• a molten salt recovery tank positioned under the porous filter in the heating furnace to collect molten salt passing through the porous filter, wherein the valve assembly comprises a pneumatic cylinder actuator provided at the sealing lid, and a rod-shaped valve connected to an output end of the pneumatic cylinder actuator to control the discharging valve hole.
