ABSTRACT:
An oil extracting apparatus includes a rigid oil adhering ring having a horizontally disposed ring axis and an oil adhering surface surrounding the ring axis, a driving device coupled to the oil adhering ring for driving rotation of the oil adhering ring about the ring axis, an oil scraping unit, and an oil collecting unit. At least a portion of the oil adhering ring below the ring axis is adapted to be immersed in a water body. Rotation of the oil adhering ring results in separation of the oil from the water body and in adhering of the oil on the oil adhering ring to form an oil film on the oil adhering surface of the oil adhering ring. The oil scraping unit scrapes the oil film from the oil adhering surface of the oil adhering ring. The oil collecting unit collects the oil scraped by the oil scraping unit.
