<p>Provided are a method for recovering floated oil and floating sludge, the method being capable of following the fluctuations of the liquid surface and efficiently drawing oil and sludge floating on the upper surface of a liquid and capable of achieving said effect using very low cost equipment, and a device therefor. The means for said purpose are a method for recovering floated oil and floating sludge and a device therefor. The method is characterized in that: two or more floats, which are for positioning an inlet port into which the floated oil, sludge, or liquid (mixed liquid) in a tank is made to flow, a flexible hose or inflow tube that is connected to said inlet port, and the inlet port thereof at the tank liquid surface, are secured; a sealed suction chamber is disposed at least 30 mm or more therebelow in order to obtain a level difference such that the mixed liquid from the inlet port of the flexible hose or the inflow tube will flow into same under atmospheric pressure; and an air pipe or inflow tube is provided to always keep the sealed suction chamber at atmospheric pressure.</p> |
