<p>A device is disclosed for removing oil, any other fatty substance or impurities from the surface of a liquid in a basin. The device comprises a rotatable drum (9) with annularly disposed bristles (10) on its surface and a comb-like scraper means (6) disposed relative to the drum so that the teeth of the scraper means extend inbetween the bristles (10) of the annular bristles (10) in the tangential direction of the drum. A collector means (7) is disposed in connection with the scraper means so that substance detached from the bristles by the scraper means can be directed to the collector means. The drum is located in a casing-like body (1) open at least on one side (2) so as to allow liquid to enter the casing and to contact the bristles (10) of the drum. The device is adapted for attachment or suspension at the edge of a basin and it is equipped with adjusting means (5) for vertical adjustment relative to the liquid level in the basin. Furthermore, the casing-like body comprises laterally outwardly directed liquid discharge nozzles (3) located substantially at the liquid level and generating a surface current in the basin, so as to continuously absorb fresh surface layer into the device as the drum rotates. The drum (9) may be rotated by an electric motor (8).</p> |
