Abstract
The invention is a particle separator which separates entrained particulates from a fluid. The particle separator utilizes an auger enclosed within a cylinder to form a cyclonic chamber, through which air is propelled. The centrifugal motion of particles within the air causes the particles to exit the cyclonic chamber through ducts, and the particles are separated in collection chambers.

A vortex particle separator, for separating entrained particulates from air, comprising:
- a vacuum housing, with at least one sidewall, a top end and a bottom end;
- at least one air inlet in said housing, for entry of air into said housing;
- at least one spiral ramp enclosed by a generally cylindrical core shroud, in which said spiral ramp comprises a top end, and bottom end, and an inside edge and an outside edge,
- with said generally cylindrical core shroud comprising a sidewall with an interior surface and an exterior surface, said generally cylindrical core shroud surrounding and enclosing said spiral ramp, with said interior surface of said generally cylindrical core shroud adjacent to said outside edge of said spiral ramp and thereby confining air to a path formed by said spiral ramp, with said generally cylindrical core shroud forming an air chamber between said housing and said exterior surface of said generally cylindrical core shroud, and forming a cyclonic chamber inside said generally cylindrical core shroud, and in which said spiral ramp provides a spiral route for air movement through said cyclonic chamber, said sidewall of said generally cylindrical core shroud defining one or more debris openings located between flights of said spiral ramp, for extracting particulates from air moving through said spiral ramp in said core shroud;
- a top portion of said housing;
- a bottom portion of said housing;
- a means of removing accumulated particulate debris from said air chamber;
- an air propulsion unit for propelling air through said vacuum housing and out said air outlet;
- and
- an operative connection between said air propulsion unit and cyclonic chamber;
- wherein said air propulsion unit propels air through said air inlet in said housing, and as air enters said spiral ramp said air is forced into a spiral path through said spiral ramp and said generally cylindrical core shroud, and entrained particulates in air are forced to a periphery of said spiral ramp by centrifugal force, and said particulates are excluded from said cyclonic chamber of said generally cylindrical core shroud to said air chamber by said one or more debris openings defined in said sidewall of said core shroud between flights of said spiral ramp, and when air passes from said housing through said air outlet it is substantially debris free.
