REACTOR Russian patent published in 1999 - IPC

FIELD: uranium production equipment for uranium oxide fluorination. SUBSTANCE: reactor has reaction tube with reaction zone, material charging zone, tube end sealing units, stirring rod with blades for material agitation and transport installed on hollow cooled shaft which is mounted in bearing supports, pipe unions for admitting chemical agents, discharging products of reaction, admitting and discharging the coolant. Reaction tube sealing unit accommodates filter in the form of shell concentric with shaft and provided with bottom of corrugated filter strainer. X-shaped stirring blades are mounted in reaction zone so that they are overlapping preceding and next blades; Y-shaped blades are mounted in charging zone. They are spaced apart at distance greater than reaction-zone blades. EFFECT: improved reliability and service life of reactor, improved quality of uranium hexafluoride obtained. 5 cl, 5 dwg
