An arrangement for separation of a surface layer, especially a layer of oil, from a liquid bath comprises a float-supported funnel 1 whose upper wider edge is arranged to be held by the float 2 essentially horizontal at a slight distance t below the surface of the bath, guide rails 4 at the upper part of the funnel, arranged to make the flow of liquid separated by the funnel flow along a helical path in the funnel with diminishing diameter, and a drain line 5, 6, 7 connected to the lower narrow end 25 of the funnel, which is connected to a pump. <IMAGE> |
