Title: Cement solidifying treatment of used ion exchange resin
Inventor: SUDO REI
IPC: G21F9/06
Filed: 1987-05-21
Abstract: PURPOSE:To increase admixture of resin particles, by a method wherein a small amount of Portland cement is added to a used ion exchange resin to stir up after the dewatering thereof, Portland cement and water are added to the mixture again and kneaded together to fill a container. CONSTITUTION:Normally, a slurry of an ion exchange resin used containing a substantial amount of water is held in a resin tank 1 and the resin slurry is transferred with a slurry pump 2 to a dewatering machine 3. Here, after the removal of tree water, the slurry is fed into a kneading machine 4. A small amount of Portland cement is added to the kneading machine 4 from a cement hopper 5 to stir up resin particles and the cement powder thoroughly with an agitation blade provided on the bottom of the kneading machine 4. Then, proper amounts of Portland cement and water are added to the mixture and kneaded again by agitation. Thereafter, the material thus kneaded fills a drum 7 to solidify. This enables the removal of a factor to cause expansion when a solidified body is immersed into water thereby increasing admixture of the resin as compared with the conventional type.
