Title:
VACUUM-SEPARATING COMPOUND TUBE, AND VACUUM CLEANING MACHINE AND COLLECTING MACHINE UTILIZING SAME
Document Type and Number:
WIPO Patent Application WO/2022/118426
Kind Code:
A1
Abstract:
Provided are a vacuum-separating compound tube, and a vacuum cleaning machine and a collecting machine utilizing the same, which excel in cost-effectiveness in that while having a relatively simple structure to keep manufacturing costs low, items of relatively small specific gravity can be separated from items of relatively large specific gravity even if the output of a motor is set high, and on that account, vacuumed-matter clogging and the like is controlled, thereby effectively preventing damage to and breakage of a fan or a fan case. A connection tube part 12, a vacuuming tube part 14, and a separating tube part 13 are provided; the vacuuming tube part 14 and the separating tube part 13 are provided joined integrally to the tip end of the connection tube part 12; the vacuuming tube part 14 and the separating tube part 13 are caused to merge with each other at the midsections or the base ends thereof; and the fact that the flow speed of the airflow that accompanies the vacuumed matter suctioned in through a suction port 14a drops in a confluence section 15 is utilized to separate the vacuumed matter into items of relatively small specific gravity and items of relatively large specific gravity.
