Document Type and Number:
WIPO Patent Application WO/2020/246479
Kind Code:
A1
Abstract:
Provided are a raw material discharge device, a method of processing of electronic/electrical device component scrap, and a method of raw material discharge for electronic/electrical device component scrap enabling efficient discharge of respective predetermined amounts of a raw material in which raw materials of a variety of shapes, specific gravities, and shapes are mixed together. The invention is a raw material discharge device 100 that is provided with: a storage unit 1 that is provided, at one end, with a discharge port 11 for discharging raw material, and that stores the raw material; a discharge unit 2 that is arranged on a bottom surface 15 of the storage uni1, that transports the raw material toward the discharge port 11, and that discharges same to the outside of the storage unit 1; and an adjustment unit 3 that is provided with a plurality of struts 31 that extend from above to below the discharge unit 2, and that suppresses some of the raw material with the struts 31 to adjust the amount of raw material that is discharged to the outside of the storage unit 1. The device is able to adjust: a ratio (d1/d2) of an interval (d1) between a strut 31 closest to a side surface 13, 14 of the storage unit 1 and the side surface 13, 14 of the storage unit 1, and an interval (d2) that is narrowest of the intervals between struts 31 of a center part of the storage unit 1, as well as a ratio (H1/H2) of a height (H1) from the floor of the strut 31 closest to the side surface 13, 14 of the storage unit 1 and a smallest height (H2) from the floor of a strut 31 other than the strut 31 closest to the side surface of the storage unit 1, so as to prevent clogging of the raw material being discharged to the outside of the storage unit.
