Abstract
For removing oil from a liquid surface (2), an outer circumferential area (14) of a receiving disk (1) rotated by a drive (3) is immersed in the liquid and the adhering oil is removed therefrom by strippers (42,43). The after-flow of oil to the receiving disk (1) is improved by a surface flow produced by a feed screw (11). The immersion depth of the receiving disk (1) is kept constant by a float (13). The horizontal orientation of the rotation axis (36) of the apparatus is ensured by the parallelogram-like arrangement of pivotable supporting arms.
Claims9
Apparatus for removing substances from a surface of a liquid, the liquid being contained in a container having a wall, the apparatus comprising:
- a receiving disc having a disc surface;
- float means to permit the apparatus to float on the liquid with partial immersion of said disc in the liquid;
- means for removing substances from the disc surface of the receiving disc;
- draining means for draining the substances removed by said removing means to the outside of the container;
- feed means positioned on the liquid surface for producing a surface flow normal to the disc surface, the feed means comprising a screw-like feed member;
- and
- a common drive member for driving both the receiving disc and the feed means, including a transmission gear to permit higher rotational sped of the feed means.
