<p>PURPOSE:To enable spraying of a slaked lime slurry or the like without clogging in a sprayer for said slurry by forming the nozzle in the outside circumferential part of a rotary disc body into the tapered shape flaring outward from a small diameter in the middle of the hole in continuation with the tapered surface in the chamber of the disc body. CONSTITUTION:Wear resistant rings 20, 21 are fitted and fixed in the upper and lower corner parts formed of the ceiling wall surface 12a, bottom wall surface 12b and outside circumferential wall surface 12b and outside circumferntial wall surface 15 in the chamber 12 of a rotary disc body 10. Obliquely tapered surfaces 20a, 21b are formed there toward a spray nozzle 23, and the hole 24 of the nozzle 23 is formed of a tapered hole part 24a flaring inward and a tapered hole part 24c flaring outward from the small diameter part 24b in the middle of the hole. If a slaked slurry is sprayed from the rotary disc constituted in such a way, the small solid material which may deposit in the part 24b is easily blown off by a rotary centrifugal force as the tapered hole part 24c is formed, whereby the rotary disc is kept free from clogging.</p> |
