ABSTRACT:
Improvements are made in the known apparatus for collecting effluent oil of the type such that the apparatus includes a pair of left and right side plates disposed at a predetermined distance in a forwardly opened arrangement, a weir plate mounted to said side plates as inclined in a rear-downward direction so that its opposite side edges may contact with the inner wall surfaces of said respective side plates under a water surface, a slant plate disposed with its rear end positioned above the rear end of said weir plate at the rear ends of said side plates and having its opposite side edges fixedly secured to the inner wall surfaces of said side plates, an oil leakage preventing plate positioned in the midway between the rear end of said weir plate and the rear end of said slant plate and having its opposite side edges fixedly secured to the inner wall surfaces of said side plates to form a water discharge port between said oil leakage preventing plate and the rear end of said weir plate and to form an oily water intake port between said oil leakage preventing plate and the rear end of said slant plate, an oily water intake pipe communicated with said oily water intake port, a pair of left and right wave buffer chambers which are of substantially cylindrical shape having their top and bottom ends closed and having their side walls partly cut away, and float means mounted to said side plates. The improvements exist in that said slant plate is appropriately inclined in an obliquely rear-upward direction with its rear end extended into said wave buffer chambers, and that between said wave buffer chambers and an oil pool formed as delimited by said side plates, weir plate and oil leakage preventing plate is provided a water conduit path for communicating therebetween.
