Samurai pentoxide powder recovery system using grinding residues of sintered uranium dioxide

摘要

The invention of that, it is an object of the present invention is U ₃ O ₈ in the process of changing the grinding scraps of uranium dioxide sintered body as U ₃ O ₈ powder, the powder of the U ₃ O ₈ powder recovery system for the grinding scraps of uranium dioxide sintered body It is to provide a U ₃ O ₈ powder recovery device using the grinding residue of the uranium dioxide sintered body that can freely adjust the characteristics, easy maintenance, high productivity through continuous production.;The present invention provides an apparatus for producing grinding residue of sintered uranium dioxide into U ₃ O ₈ powder; A suction part for sucking the grinding residue of the sintered uranium dioxide and charging it into the hopper of the oxidation furnace; A screw feeder installed to connect the lower side of the hopper to supply the grinding residue of the sintered uranium dioxide charged into the hopper into the oxide tube; An oxide tube connected to and installed at the other side of the screw feeder connected to one side of the hopper and converting the grinding residue of uranium dioxide transferred by the screw feeder into U ₃ O ₈ powder; A heating device installed around the tube to heat the tube; A drive unit installed at the lower portion of the oxide tube to rotate the tube and smooth the reaction speed and flow of the uranium dioxide sintered compact; A tilting unit installed below the oxide tube to give an angle of inclination to the oxide tube; An air supply device connected to the oxide tube and configured to supply air into the oxide tube and an air discharge device to discharge the air introduced into the oxide tube to the outside; A powder discharge device connected to and installed at the other end of the oxide tube to which one side of the screw feeder is connected and discharging the U ₃ O ₈ powder converted in the oxide tube to a powder storage container; A metering device which is installed at the lower end of the powder storage container and continuously measures the weight of the U ₃ O ₈ powder discharged into the powder storage container; It provides a U ₃ O ₈ powder recovery apparatus using the grinding residue of the uranium dioxide sintered compact comprising a control device for controlling the suction and hopper vibration time and cycle, air pulsing time, etc. Is in.
