Abstract

PURPOSE: To enhance classification efficiency and miniaturize the apparatus by providing a strap plate for down-flowing turbid water classification within the drum body in the rotary drum type sand classifier equipped with the spiral form sand feed vanes provided on the inside circumferential surface of the horizontally supported and rotating drum.
CONSTITUTION: The turbid water charged into the turbid water conduit 11 of the rotating drum body 1 collides against a strap plate 15 from a release and 11' and flows down along one side of the strap plate 15 in spacing 14. The most water contents fly in the arrow W along the diffraction of the circumferential edge part 15' and fly to an overflow port 9. On the other hand, sand sediments in the arrow S direction owing to flowing-down by gravity. The sand is further transferred in the cover plate 8 direction by sand feed vanes 19, is scooped up by a perforated plate 20 and is discharged through a sand outlet 10. At the time when the turbid water flows down, the water and sand are classified to a certain degree and therefore the settling and separation of the sand are rapidly accomplished, thus the higher classification efficiency and smaller apparatus are achieved.
