Dust disposal cyclones
First Claim
1. In a dust disposal cyclone of circular cross-sectional configuration having a tangential inlet for dust-laden air and an axial outlet for dust-freed air, said outlet protruding into the cyclone;
- the improvement in which the inlet has a flank facing but spaced from the outlet by a gap defined by and between said flank and said outlet and communicating between the ambient air and the interior of the cyclone, through which gap ambient air is inducted by the dust-laden air that enters through the inlet, and an arcuate baffle between the inducted air and the dust-laden air in the inlet, the baffle being arcuate in the same direction as the outer wall of the cyclone to deflect the inducted air into the same direction in which the dust-laden air from the inlet rotates in the cyclone.

Abstract
A cyclone with a tangential peripheral inlet and a central axial outlet is improved as to efficiency by inducting air between the inlet and the outlet. The inducted air is diverted by a baffle that temporarily separates it from the dust-laden inlet air, the baffle being arcuate in the same direction as the wall of the separation chamber, so that the inducted relatively dust-free air forms an inner layer and the dust-laden air forms an outer layer in the separation chamber. This promotes the separation of the dust on the inner side of the outer wall of the chamber and so facilitates separation of the dust from the air. A portion of the outlet air from which the dust has been separated can also be recycled in a stream disposed on the other side of the inducted ambient air.
