Apparatus for drying Spent Ion-Exchange Resins (SIER), which can intensify the SIER drying process, reduce power consumption, and accelerate discharge of SIER when the drying process is completed. The apparatus comprises a sealed cylindrical body, and a blow-down choke installed in an upper part of the sealed cylindrical body and a nozzle to feed the spent ion-exchange resins is installed inside the body, and a nozzle to retrieve dried ion-exchange resins is installed in its bottom part and equipped with a locking device. An external heater is provided for the body, and a drive shaft that is installed in alignment inside the body, capable of rotation, and equipped with a stirrer. A lower part of the drive shaft with lower screw winding is installed in alignment inside the nozzle to retrieve dried ion-exchange resins. The nozzle to retrieve dried ion-exchange resins is equipped with a water draining device.
An apparatus for drying spent ion-exchange resins comprising a sealed cylindrical body, in upper part of which a blow-off choke is installed and a first nozzle to feed spent ion-exchange resins inside the sealed cylindrical body is installed, in a bottom part of the sealed cylindrical body, a second nozzle is installed to retrieve spent ion-exchange resins, the bottom part of the sealed cylindrical body further includes an external heater and a drive shaft that is installed in alignment inside the sealed cylindrical body for rotation, the drive shaft is equipped with an anchor mixer that is rigidly fixed on the drive shaft, the anchor mixer includes mixer blades having a shape conforming to an internal service of the bottom part of the sealed cylindrical body and a side part of the sealed cylindrical body, wherein an upper part of the drive shaft comprises one-way screw windings and a lower part of the drive shaft comprises one-way screw windings, the lower part of the drive shaft with one-way screw windings are aligned inside the second nozzle retrieve the dried ion-exchange resins, and wherein the second nozzle forms part of a water draining device.
