Abstract
A trap for separating and retaining grease, oil, and particulates from water or other fluids. The inventive device includes a trap body having an inlet fitting extending thereinto and terminating in a deflecting cup such that fluid entering the trap flows vertically upward from the cup. A planar baffle plate extending across an interior of the trap body retains grease on a first side thereof while permitting the water to flow under the planar baffle plate to a second side thereof. An angled baffle plate also extends across the interior of the trap body and includes an angled weir for deflecting food particles and the like from passage thereover. An outlet fitting extends from below the water to permit exiting of the filtered water from the trap body.
Claims5
A grease and oil trap comprising:
- a trap body having a front wall spaced from a rear wall, a pair of side walls, a bottom wall, and a removable cover;
- an inlet fitting directed through said trap body proximal to said front wall thereof, said inlet fitting extending into an interior of said trap body;
- an outlet fitting directed through said trap body proximal to said rear wall thereof, said outlet fitting extending into said interior of said trap body;
- a planar baffle plate extending across said interior of said trap body and being coupled to interior surfaces of said side walls, said planar baffle plate being spaced from an interior surface of said bottom wall so as to permit fluid to pass thereunder, said planar baffle plate separating said interior of said trap body into a first compartment and a second compartment;
- a second baffle plate extending upwardly from said interior surface of said bottom wall of said trap body within said second compartment, said second baffle plate being coupled to interior surfaces of both said side walls, said second baffle plate including a straight portion having an upper edge and extending in a substantially spaced and parallel orientation relative to said planar baffle plate, and an angled weir coupled to said upper edge of said straight portion, said angled weir projecting from said straight portion at an oblique angle relative to said straight portion and towards said planar baffle plate, said angled weir portion projecting substantially upwardly from the straight portion and terminating in an angle weir upper edge positioned above said upper edge of said straight portion, said angled weir projecting towards both said removable cover of said trap body and said inlet fitting;
- an inlet T-connector coupled to said inlet fitting within said interior of said trap body;
- a center tube projecting downwardly from a second lower end of said inlet T-connector;
- and an imperforate deflecting cup mounted to a lower end of said center tube for redirecting and decelerating fluid entering said trap body, said deflecting cup comprising a substantially cylindrical side wall closed at a lower end thereof by a hemispherical dome, said cylindrical side wall being open at an upper end thereof, said open upper end of said cylindrical side wall of said deflecting cup being aligned with a lowermost portion of said outlet fitting so as to define a water line within said trap body, said water line being aligned with the upper end of the cylindrical side wall and with both the angled weir upper edge and the lowermost portion of the outlet fitting.
