Abstract
A coated metal drum (38) for a skimmer apparatus mounted on a buoyant frame (10) floating on a body of water for removal of hydrocarbon material from the body of water. The coated drum (38) has a metal drum base (80) which is blasted to provide a roughened cylindrical surface for the coating (84, FIG. 4). The coating comprises a vinyl ester resin material which is sprayed in a plurality of layers (86) onto the roughened metal surface and is cured to provide a hard abrasion resistant surface for the adherence of hydrocarbon material thereon.
Claims8
A coated cylindrical drum rotatably supported on a skimmer apparatus floating on a body of water for removal of hydrocarbon material from the body of water;
- said coated cylindrical drum comprising:
- a cylindrical metal base having an outer cylindrical roughened surface;
- and
- an outer vinyl ester resin coating secured to said metal base and having a plurality of layers sprayed onto said metal base at separate time intervals to provide a coating thickness between about 0.018 inch and about 0.025 inch, said coating having an outer cylindrical surface with a rough texture to provide a roughened tractive surface for the hydrocarbon material to be removed from the body of water.
In a skimmer device for recovering material from the surface of a body of water having a buoyant frame floating on the body of water including a collection reservoir, a generally cylindrical rotary drum rotatably supported on said buoyant frame and defining a cylindrical outer surface for recovering material from the surface of the body of water, and a scraper device having scraping contact with said cylindrical surface of said drum with material scraped from said cylindrical surface of said drum deposited into said collection reservoir;
- said drum having an improved coating thereon and comprising:
- a cylindrical metal base having a roughened outer cylindrical surface;
- and
- an outer vinyl ester resin coating on said cylindrical metal base forming said cylindrical outer surface for contact by said scraper device, said vinyl ester resin coating having a rough textured surface for engagement by said scraper and for providing a roughened traction surface for the hydrocarbon material to be recovered from the surface of the body of water, said outer vinyl ester resin coating having a plurality of layers sprayed onto said metal base at separate time intervals to provide the desired coating thickness.
