Abstract:
A material handling system for conveying flowable material comprising:an outer barrel having an inlet plate with an inlet opening, an outlet end and an interior cylindrical surface; an accelerating chamber having an inlet end and an outlet end, the inlet end of the accelerating chamber extending concentrically from the outlet end to the outer barrel, the accelerating chamber having a substantially conical interior surface that converges in a direction from the inlet end to the outlet end; an inner barrel having an exterior surface with a first end and a second end, the inner barrel located concentrically inside the outer barrel, wherein the outer barrel and the accelerating chamber are arranged to form an annular space between the interior cylindrical surface of the outer barrel and the exterior surface of the inner barrel, the annular space extending from the first end of the exterior surface of the inner barrel to the substantially conical interior surface of the accelerating chamber; deflecting means proximate to the inlet opening for directing the flowable material tangentially to the interior cylindrical surface of the outer barrel to set up a flow pattern in the annular space such that a material flowing from the inlet conduit into the outer barrel will circulate around the inner barrel and traverse the annular space from the inlet plate toward the outlet end of the outer barrel; wherein the inlet opening on the inlet plate is configured to direct the flowable material through the outer barrel into the annular space; and wherein the first end of the inner barrel is adjacent to the inlet plate and the second end of the exterior surface of the inner barrel is adjacent to the accelerating chamber.
