Abstract
A device for separating, in an ice environment, fluids having differing physical properties which combine an oleophilic pick-up device with a rotating tumbler mechanism which tends to agitate and propel oil coated pieces of ice rearward and along a perforated inclined through-put barrier where oil jarred off the ice chunks is allowed to rise through the perforations and be contained in an area where it can be accumulated and recovered by the pick-up unit.
Claims5
A device for separating oil from water and pieces of floating ice comprising
- spaced side support members, adapted to extend beneath a water surface, constituting a channel area,
- rotational oil pickup means journalled between said side supports,
- a perforate through-put barrier, adapted to be submerged in operation, having an inclined under surface and forward and rearward edges, said forward edge secured between said side supports adjacent said pickup means and positioned to be able to receive submerged pieces of ice against its under surface,
- a containment backstop hingedly attached to the rearward edge of said barrier and extending between said side supports, thus to form between said pickup device and said side members a containment ponding area for accumulated oil,
- and a rotatable tumbler bar journalled between said side members and positioned generally between the forward edge of said barrier and the lower periphery of said pickup means.
A device for separating oil from water and pieces of floating ice comprising
- spaced side support members having their lower surfaces adapted to extend beneath the surface of water on which they may be positioned, the area between said side support members constituting a channel area,
- a generally drum-like oil pickup means extending between said side supports with the lower portion thereof adapted to be positioned beneath the water line,
- a rotatable tumbler bar journalled between said side support members and extending next adjacent and generally parallel to the surface of said drum-like pickup means in a lower quadrant thereof,
- a perforate throughput barrier secured between said side supports and pivotable at one end about an axis generally parallel to and next adjacent the lower surface of said tumbler bar on the side thereof opposite to said drum-like pickup means,
- a backstop hingedly mounted to the opposite end of said throughput barrier and adapted to extend generally between said side support members,
- and backstop adjustment means associating said backstop with said side support members for raising and lowering said backstop, thus to adjust the angle of inclination of said throughput barrier about said pivot axis.
