1450111 Skimming device J RAFAEL 24 Sept 1973 [25 Sept 1972] 44645/73 Heading BID [Also in Division B7] A device for removing oil from open water comprises a floating body with an adjustable overflow lip 4 to skim off the top surface layer into chamber 2 which has an arched roof lying wholely lower than lip 4, oil being discharged through outlets 13, possibly by a suction pump, to a further settling stage (not disclosed) and water being discharged by pump 14. Restricted outlets 10, 11 reduce the speed of the upper layers of water in chamber 2 to give the oil droplets time to rise. The device of Fig. 1 may be constructed as a self-propelled ship. Alternatively a plurality of such devices (Fig. 2. not shown) are hinged together to accommodate to wave motion and suspended over the side of an oil-collecting ship by outrigger cranes (16, 17). Valve 15 enables the device to be pumped dry for easy manoeuvring. Flap 6 acts as a non-reverse valve in conjunction with lip 4. Lip 4 is hinged to the body at 4a and supported by floats 5. |
