SPILLED OIL RECOVERY DEVICE AND SPILLED OIL RECOVERY VESSEL

摘要

The present invention addresses the problem of providing a spilled oil recovery device that can be easily mounted in a vessel and can easily recover spilled oil not only in the ocean but also in a narrow harbor, and a spilled oil recovery vessel equipped therewith. A spilled oil recovery device comprises a screw conveyor in which a screw is rotatably housed along the axial direction within a cylindrical casing having a recovery port and a discharge port, and which conveys oily water containing spilled oil taken in from the recovery port to the discharge port by the rotational force of the screw, and a spilled oil recovery vessel is provided with this spilled oil recovery device. In the screw, the rotating shaft thereof extends along the axial direction of the casing, and a helical blade is continuously formed along the rotating shaft.
