  • Apparatus for removing substances from the surface of a liquid
    Patent number: 5167815
    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.
