Title:
WIND FORCE STATIC SELECTION DEVICE
Document Type and Number:
Japanese Patent JP3280831
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To improve the fractionation accuracy for light weight plastics and the like by utilizing the ionic wind generated by corona discharge.
SOLUTION: An ionic wind area blowing ionic wind EW from an electrode unit 14 toward a conductive rotor 11 is formed on a selection flow path 13 flowing down along the tangential direction to the conductive rotor 11. This device is provided with a conductive trash recovering tray 21 for guiding conductive trash Da passing through the ionic wind area and discharged downward, a semiconductive trash recovering duct 22 for attracting separation of the semiconductive trash Db of weak attraction force from crushed trash D blown up by the ionic wind EW and attracted on the conductive rotor 11, and a conductive trash recovering tray 23 for discharging semiconductive trash Dc attracted and rotated on the conductive rotor 11.
