Title: Device for sink-and-float sorting of waste plastic pieces
Inventor: FUJINO KIYOSHI
IPC: B03B5/28
Filed: 2001-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a device for sink-and-float sorting of waste plastic pieces capable of precise sink-and-float sorting of waste plastic pieces in a relatively small water tank. SOLUTION: The device is equipped with a screw conveyor 7, set on the upstream side from a water tank 2 having a constant direction of water flow, to push and sink waste plastic pieces in the water, and shields 12 to make the water flow meander in the water tank 2.
