A multi stage separator for separating fluid and material. The conduit has a series of tubes arranged to convey material in a fluid stream with the last tube emptying into a receptacle. Each tube is separated from the prior tube forming exhaust vents whereat at least some of the fluid from the stream is exhausted. The downstream tube at each vent has a smaller cross-sectional area as compared to the adjacent upstream tube with a cone shaped vane extending outwardly to direct the exhausting fluid. The heavier than fluid material is provided with sufficient kinetic energy by the reduced size tubes to allow the fluid to exhaust while the material flows along the longitudinal axis of the tubes.

[ What is claimed is:] [1.] A multi stage separator for separating material from a fluid stream comprising:a conduit including an inlet for collecting and receiving material and a material outlet through which said material exists said conduit, said conduit including a first primary fluid outlet located between said inlet and said material outlet, said conduit further including a first internal cross sectional area located between said inlet and said primary fluid outlet and a second internal cross sectional area located between said primary fluid outlet and said material outlet with said second internal cross sectional area sized smaller than said first internal cross sectional area to maintain forward movement of material in said conduit although at least some of said fluid is exhausted at said primary fluid outlet;a receptacle connected to said material outlet receiving said material; and,pressure means to pull fluid and said material into said inlet, some of said fluid out said primary fluid outlet and said material through said conduit and into said receptacle; wherein:said conduit includes a second primary fluid outlet located between said first primary fluid outlet and said material outlet, said conduit further includes a third internal cross sectional area located between said second primary fluid outlet and said material outlet with said third internal cross sectional area sized smaller than said second internal cross sectional area to maintain forward movement of material in said conduit although at least some of said fluid is exhausted at said second primary fluid outlet,said conduit includes a third primary fluid outlet located between said second primary fluid outlet and said material outlet, said conduit further includes a fourth internal cross sectional area located between said third primary fluid outlet and said material outlet with said fourth internal cross sectional area sized smaller than said third internal cross sectional area to maintain forward movement of material in said conduit although at least some of said fluid is exhausted at said third primary fluid outlet,said conduit includes at said first primary fluid outlet, said second primary fluid outlet and said third primary fluid outlet separate funnel shaped walls extending outwardly therefrom and diverging outwardly in an upstream direction from said material outlet toward said inlet, said second internal cross sectional area remains constant from first primary fluid outlet to said second primary fluid outlet, said third internal cross sectional area remains constant from said second primary fluid outlet to said third primary fluid outlet, said fourth internal cross sectional area remains constant from said third primary fluid outlet to said material outlet.
