Patent ID: 7811526

Claim:
A device for recovering a feedstock liquid, comprising a remaining feedstock liquid collector, placed between a dripping nozzle or dripping nozzles of a dripping nozzle device that comprises the dripping nozzle or dripping nozzles for dripping the feedstock liquid including uranyl nitrate to an aqueous ammonia solution, the dripping nozzle or dripping nozzles being placed above an aqueous ammonia solution reservoir so that an opening or openings of the dripping nozzle or dripping nozzles are directed downward and face the aqueous ammonia solution, wherein the feedstock liquid is transferred from a feedstock liquid reservoir having a temperature-controlling function through a feedstock liquid transferring passage to the dripping nozzle or nozzles and the aqueous ammonia solution reservoir in which an aqueous ammonia solution is stored, said remaining feedstock liquid collector for receiving a remainder of the feedstock liquid remaining in the feedstock liquid transferring passage when the dripping of the feedstock liquid from the dripping nozzle or nozzles to the aqueous ammonia solution is stopped; and a feedstock liquid remainder transferring passage for transferring the remainder to the feedstock liquid reservoir.
