PURPOSE:To improve the cooling efficiency and enable easy and rapid internal washing upon maintenance and the like of the title machine related to the machine suitable for efficiently cooling a high-temperature pulverized body obtained by heating and drying a waste liquid generated in an atomic power station for subjecting the waste liquid to a solid treatment. CONSTITUTION:In the horizontal type cooling machine internally provided with a rotary shaft 4 mounted with a plurality of disks 3, an arc-shaped plates 10 are mounted on the rotary shaft 4 at an angle in a range of 5-35 deg., preferably at an angle in a range of 10-30 deg., with respect to the rotary shaft 4. In this case, if the arc-shaped plates are mounted on the rotary shaft in parallel thereto (an angle of zero with respect to the rotary shaft), no feeding effect of the pulverized body is produced. Further, if the mounting angle is too large, the feed of the pulverized body is too fast, the pulverized body is discharged while it is not yet sufficiently cooled. Therefore, the angle (alpha in Fig.) formed between the arc-shaped plate and the rotary shaft is selected to 5-35 deg., preferably 10-30 deg.. |
