Abstract:
1. A cyclonic dust collector arrangement, comprising; a conic body having a conic wall, an upper divider plate closing off an upper end of the conic body, the divider plate having a central passage and a vortex tube descending from the central passage, and the conic body having a narrow nose at a lower end of the conic wall, the upper divider plate and the lower nose defining a cyclonic chamber within the conic body; an air inlet conduit penetrating said conic wall below said divider plate; a fan chamber formed of a generally annular side wall extending circumferentially atop the upper end of said conic body and a top plate closing off said side wall; means mounting the fan chamber atop said conic body; a fan disposed in said fan chamber and adapted to induce a flow of air from said air inlet conduit into said cyclonic chamber, and through said vortex tube into the fan chamber; an air outlet duct conducting air flow from said fan chamber, and exiting through a penetration in said fan chamber; a dust barrel positioned below said nose and having a lid closing off a top of the dust barrel, the lid having a dust inlet opening; and means for coupling the nose of the conic body to the inlet opening of the lid, such that dust separated from the air flow in said cyclonic chamber drops out from said nose into the dust collection barrel.
