Claims

[Scope of utility model registration request]

An air suction fan that is fixed in multiple stages to a rotating shaft that stands upright with its axes substantially aligned in an outer cylinder that receives pellets in the form of a slurry together with water, a pellet outlet, a drain port, and an air intake port. a rotor consisting of a plurality of multi-tough individual long plates fixed to the outer edge of the fan so as to be inclined in the radial direction with a gap between them; blades for scraping up pellets fixed in multiple stages on the outside of the rotor; A centrifugal motor consisting of a punching plate provided with a gap around the outer periphery of a scraping blade, an upper receiver provided at the upper end of the punching plate containing a plate, and a lower receiver provided at the bottom of the rotor containing a plate. In the dryer, a large number of small diameter punching holes or small slits are provided in the lower part of the punching plate, and a large number of large diameter punching holes or large slits are provided in the upper part, and the small diameter punching holes or small slits and the large diameter punching holes are provided. Or, between the large slit part and the outer cylinder of the punching plate, a partition plate is provided that slopes downward toward the outer cylinder,
A pellet storage groove was provided on the outside of the outer cylinder with the openings provided in the outer cylinder at the outer end of the partition plate and the upper part thereof as pellet inlets, and a pellet discharge outlet was provided in the pellet storage groove and an air nozzle was inserted. Features: A dry classifier for synthetic resin pellets.
