Title:
DISCHARGE MECHANISM OF CYCLONE CLASSIFIER, CYCLONE CLASSIFIER, AND POLISHING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/004280
Kind Code:
A1
Abstract:
An embodiment presents a discharge mechanism, which is provided in a cyclone classifier that classifies particulate matter and which discharges particulate matter stored in a storage part of the cyclone classifier. The discharge mechanism is provided with an opening-closing member for opening and closing a discharge port formed in the storage part and a sprayer for spraying a compressed gas in pulses on the particulate matter stored in the storage part. The opening-closing member is configured so that: when compressed gas is sprayed from the sprayer, the opening-closing member is subjected to a pressing force due to the compressed gas and opens the discharge port; and when compressed gas is not being sprayed from the sprayer, the opening-closing member is biased toward the storage part by the negative pressure in the storage part, closing the discharge port.
