Abstract

An elbow has an elongated inlet, an elongated outlet tube that merges with the inlet at a shallow angle, and an endwall opposite the inlet. The round inlet receives product and leads to a first chamber with a rounded bottom. Opposite the bottom, the inlet has a pitch at the transition to the outlet tube. The outlet tube continues upwardly from the pitch to an exit. Within the outlet, a third chamber extends from the first chamber. The first chamber and the third chamber intersect at the second chamber that provides a transition to the flow of product from the first chamber to the angle of the third chamber. Within the second chamber, conveyed product forms a shallow eddy so that additional product flows over the eddy enroute to the outlet.

Claims

1. An elbow for effecting shallow angular adjustments in product flow there through without excessive wear upon said elbow, comprising:

an inlet;

an outlet opposite said inlet;

an outlet tube extending inwardly from said outlet towards said inlet, said outlet tube attaining a shallow angle relative to said inlet;

a first chamber extending inwardly from said inlet, said first chamber having a generally cylindrical shape;

a third chamber extending inwardly from said outlet, said third chamber having a generally cylindrical shape; and

,

a second chamber forming from the merging of said first chamber with said third chamber inwardly from said inlet, said second chamber having a partially conical shape;

wherein said elbow conveys product through said first chamber, then said second chamber, and into said third chamber.

2. The shallow angle elbow of claim 1 further comprising:

a bottom, generally hollow, extending rearwardly from said inlet;

an end, generally partially spherical joining to said bottom opposite said inlet;

said first chamber forming within said bottom;

an endwall joining above said end;

a recurve joining above said endwall;

two mutually parallel and spaced apart sidewalls, generally triangular in shape, extending along said outlet tube and said bottom, widening away from said inlet;

said second chamber forming within said endwall, said recurve, and said sidewalls.

3. The shallow angle elbow of claim 2 further comprising:

said end, said endwall, and said recurve having similar radii.

4. The shallow angle elbow of claim 2 wherein said end curves opposite that of said recurve.

5. The shallow angle elbow of claim 1 wherein said outlet tube attains an angle of approximately twenty degrees relative to said inlet.

6. The shallow angle elbow of claim 1 wherein the angular displacement of the third chamber relative to the first chamber is at a fixed angle, and the angular displacement of the second chamber is at an elevated angle from the longitudinal access of the first chamber, but less than the angular displacement formed between the third chamber and the first chamber in the structured elbow.
