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 blow-off choke is installed and a nozzle to feed spent ion-exchange resins inside the body is installed, as well as in its bottom part, the nozzle is installed to retrieve spent ion-exchange resins and it is equipped with the locking device, the external heater for the body and the drive shaft that is installed in alignment inside the body including possibility of its rotation, and it's equipped with the stirrer, it's proposed to make the stirrer as an anchor mixer that is rigidly fixed on the drive shaft, the mixer blades shall follow the shape of internal surface of bottom and side part of the body and located on the drive shaft upper and lower the place where the anchor mixer is fixed including upper and lower one-way screw windings, by this, lower part of the drive shaft with lower screw winding shall be installed in alignment inside the nozzle to retrieve the dried ion-exchange resins and the nozzle to retrieve the dried ion-exchange resins shall be equipped with the water draining device.
