び装置（ボール型乾燥機）を、特願昭58−159388
号および特願昭59−44724号により提案している。(Prior technology) Liquid or slurry radioactive waste, such as radioactive liquid waste, waste resin, and waste sludge, generated in nuclear power plants and other facilities that handle radioactive materials is concentrated or dehydrated, then mixed with cement and solidified in drums. It is common to store them inside the facility.
Furthermore, attempts have been made to mix and solidify the powder with plastics and the like using an externally heated centrifugal thin film dryer. However, the former method has poor solubility reduction properties, and the latter method has drawbacks such as frequent failures of the dryer, which rotates at high speed, and a small processing capacity due to indirect heating. Therefore, in order to eliminate these drawbacks, the applicant provided a support plate with a large number of holes inside the container-shaped body, and rolled the spherical bodies deposited on this support plate with stirring blades. Patent application No. 58-159388 describes a method and device (ball-type dryer) for heating and drying a liquid substance that descends along the body and turning it into powder.
No. 1 and Japanese Patent Application No. 59-44724.

る。 In the apparatus configured as described above, the liquid material 22 consisting of radioactive waste such as radioactive waste liquid, concentrated waste liquid, slurry of waste sludge, etc. is fed by the pump 23 and is supplied from the liquid material supply port 14 onto the deposited layer of the spherical bodies 13. The powder flows down along the surface of the spherical body 13 heated by the hot air of 200° C. or more from the hot air generator 17, is dried by the spherical body surface and the hot air, becomes powder 24, and falls downward. . liquid 2
If the powder 2 is in the form of a slurry, the powder 24 may pass through the support plate 3 without being completely dry, and at this time the powder 24 tends to adhere and accumulate in the slit 6, but the pin 12 It is driven by a drive shaft 9 and constantly rotates inside the slit 6 to scrape off the powder 24 adhering to the inside of the slit 6 to prevent clogging. In addition, even if the spherical body 13 were to break, the pin 12 would similarly prevent debris from clogging the slit 6, allowing small debris to fall downward, and large debris to move on the support plate 3 while being removed from other debris. Spherical body 13
It also contributes to dryness. On the other hand, hot air containing evaporated water flows out from the exhaust port 18, is removed by a dust remover 19, and is then discharged into the atmosphere by an exhaust fan 20.

などしてもよい。 In the above embodiment, the width of the slit 6 is constant in the vertical direction, but if the width of the slit 6 is narrower in the upper part and wider in the lower part, the powder 24 is likely to peel off and fall from the side wall of the slit 6, resulting in clogging. The prevention effect will be improved. Further, as shown in FIG.
It is more preferable if the powder 24 and the fragments of the spherical body 13 firmly stuck to the side wall of the slit 6 can be surely scraped up and removed. Note that the pin 12 may be provided protruding from the lower surface of the stirring blade 10,
Furthermore, in addition to the stirring blades 10, a dedicated bar or the like may be fixedly protruding from the drive shaft 9, and a pin 12 may be fixedly attached to this bar.

るが、他の断面形状とすることも可能である。 Further, in the above embodiment, since the upper surface 11 of the stirring blade 10 is inclined downward in the direction of movement of the stirring blade,
Since the spherical body 13 can be easily scooped up and the resistance force received from the spherical body 13 is small, the power consumption of the rotating device 8 can be reduced, and fragments of the spherical body on the support plate 3 can also be scooped up. Therefore, it has the advantage of preventing the accident of being caught between the stirring blade 10 and the annular body 4, but other cross-sectional shapes are also possible.
