Title:
ELECTROSTATIC SORTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2011/016520
Kind Code:
A1
Abstract:
In conventional electrostatic sorting apparatuses that use plate-shaped electrodes, in order for sorting precision to not decrease due to an electrostatically charged material to be sorted colliding with the plate-shaped electrodes, and then rebounding from the impact, disclosed is a electrostatic sorting apparatus that has at least one set of rod-shaped anodes that apply a positive voltage; at least one set of rod-shaped cathodes that are disposed facing the aforementioned cathodes and that apply a negative voltage; an insertion port that is disposed above the space between the aforementioned facing electrodes and that is for inserting the charge-treated material to be sorted; and a retrieval unit that is disposed under the aforementioned rod-shaped electrodes and that retrieves the aforementioned charge-treated material to be sorted that drops down having been deflected according to charge characteristics in the electric field generated by means of the aforementioned rod-shaped anodes and rod-shaped cathodes.
