First Claim
Patent Images
1. A cyclone separator for separating entrained particles from a fluid flow, the separator comprising:
- a) a cyclone chamber having a centre and a cyclonic flow region;
b) a fluid inlet for introducing a cyclonic fluid flow to the cyclonic flow region;
c) a fluid outlet for removing the fluid flow from the cyclone chamber;
d) a particle separating member positioned in the cyclone chamber beneath the cyclonic flow region, the particle separating member having an upper surface and a plurality of apertures;
e) a particle receiving chamber disposed beneath the particle separating member for receiving particles separated from the fluid flow, the particles passing into the particle receiving chamber through the apertures; and
, f) a plurality of baffle members positioned in the particle receiving chamber.

Abstract
A particle separation member is provided for use with a cyclone separator. The particle separation member divides the separator into a cyclone chamber and a particle receiving chamber. The cyclone chamber and the particle receiving chamber communicate via a plurality of apertures in the particle separation member. The apertures have baffle members for reducing the flow of fluid in the particle receiving chamber.

21. The separator of claim 19 wherein the apertures are configured to inhibit reentrainment of particles from the particle receiving chamber to the cyclonic flow region.
-
22. A separator for separating entrained particles from a fluid low, the separator comprising:
-
(a) a cyclone chamber for containing a cyclonic flow in a cyclonic flow region;
(b) means for introducing a fluid flow to the cyclone flow region for cyclonic rotation therein;
(c) means for removing the fluid flow from the cyclone chamber;
(d) particle receiving means disposed beneath the cyclone flow region for receiving particles separated from the fluid flow;
(e) separation means for dividing the particle receiving means from the cyclone chamber;
(f) transporting means associated with the separation means for connecting the particle receiving means in flow communication with the cyclonic flow region such that, in operation, particles pass through the transporting means to the particle receiving means; and
,(g) flow disruption means beneath the separating means for disrupting cyclonic fluid flow in the particle receiving means. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
