Title:
ELECTROSTATIC SEPARATOR AND ELECTROSTATIC SEPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/166178
Kind Code:
A1
Abstract:
An electrifying part (2) agitates a plastic piece group (11) which is a mixture of a plurality of types of plastic pieces (11a, 11b), and electrifies each plastic piece. Electric field generation parts (4-6) apply an electric field to each of the electrified plastic pieces. A recovery box (7) recovers the plastic pieces which have fallen from the electric field generation parts. A partition plate (8 or 9) is disposed so as to be movable in the X direction in the recovery box. A control device (10) is configured to sample a portion of the plastic piece group, measure the composition ratio of the plurality of types of plastic pieces, analyze the variation tendency of the composition ratio by using the composition ratio measured in the past and the composition ratio measured this time, and control the position of the partition plate on the basis of the results of the analysis.
