Abstract

A distributor device for use with cyclone separator apparatus, the distributor device comprising, a main body having a distribution chamber therein, the main body including a back wall and a front wall which at least in part enclose the distribution chamber, the main body including a peripheral region between the front and back walls, the device comprising a plurality of delivery outlets arranged in spaced apart relation around the peripheral region the front wall having an inner face and a back wall having an inner face, the device further including a feed inlet to the distribution chamber in the front wall having a main axis extending in a direction between the front and back walls; the back wall having an inner face which includes main face section and a protrusion which extends from the main face section towards the inner face of the front wall.

First claim

The invention claimed is:

1. A distributor device for use with cyclone separator apparatus, the distributor device comprising, a main body having a distribution chamber therein, the main body including a back wall and a front wall which at least in part enclose the distribution chamber, the main body including a peripheral region between and surrounding the front and back walls to define a side wall, the device comprising a plurality of delivery outlets arranged in spaced apart relation in and around the side wall of the peripheral region, the front wall having an inner face and the back wall having an inner face, the device further including a feed inlet to the distribution chamber in the front wall having a main axis extending in a direction between the front and back walls; the inner face of the back wall including a main face section and a protrusion which extends from the main face section towards the inner face of the front wall, wherein the feed inlet comprises an inlet passage which includes an outer section which is cylindrical in cross section and an inner section which is flared outwardly in cross section from the outer section in the direction of the front wall, wherein the flared inner section is curved in a trumpet shape, wherein the flared inner section blends into the inner face of the front wall providing a continuous uninterrupted blended surface leading from the inlet passage to the delivery outlets to deliver fluid to a point at the peripheral region of the main body, wherein the inner face of the front wall and the inner face of the back wall are substantially parallel in a region of the main face section of the back wall.

2. The distributor device according to claim 1 , wherein the protrusion has a curved profile including (i) curved side regions, wherein the curved side regions extend inwardly into the distribution chamber from the main face section of the back wall and toward the inner face of the front wall, and (ii) a curved apex region remote from the main face section and disposed at a position between both the back wall and the front wall and at least partially encircled by the peripheral region.

3. The distributor device according to claim 2 , wherein the apex region has a central part which is in line with the main axis of the feed inlet.

4. The distributor device according to claim 1 , wherein each delivery outlet has a delivery passageway terminating with an aperture at the peripheral region and configured so as to increase discharge speed from the distribution chamber.

5. The distributor device according to claim 4 , wherein each delivery passageway is tapered inwardly from an inner end adjacent the distribution chamber towards an outer end and defines at least a portion of the aperture that is through the peripheral region and extending from the back wall to the front wall.

6. The distributor device according to claim 5 , wherein the delivery outlets comprise nozzles.

7. The distributor device according to claim 4 , wherein adjacent delivery outlets are arranged in close proximity to one another with a junction region therebetween, each junction region having a curved leading edge portion with respect to a direction of flow through the delivery outlets.

8. A cyclone separator apparatus comprising a support frame, a plurality of cyclone separators mounted to the support frame and radially disposed above a main axis of the support frame, a delivery line for delivering material to a distributor device or manifold that includes: a main body having a distribution chamber therein, the main body including a back wall and a front wall which at least in part enclose the distribution chamber, the main body including a peripheral region between the front and back walls defining a peripheral side wall, the device comprising a plurality of delivery outlets arranged in spaced apart relation around the peripheral side wall, the front wall having an inner face and the back wall having an inner face, the device further including a feed inlet to the distribution chamber in the front wall having a main axis extending in a direction between the front and back walls; the inner face of the back wall including a main face section and a protrusion which extends from the main face section towards the inner face of the front wall, wherein each cyclone separator being operatively connected to the distributor device or manifold, wherein the feed inlet comprises an inlet passage which includes an outer section which is cylindrical in cross section and a flared inner section comprising a trumpet shape and which is flared outwardly in cross section from the outer section in the direction of the front wall, wherein the flared inner section is curved, wherein the flared inner section blends into the inner face of the front wall providing a continuous uninterrupted blended surface leading from the inlet passage to the delivery outlets, and wherein the inner face of the front wall and the inner face of the back wall are substantially parallel in a region of the main face section of the back wall.

9. A distributor device for use with cyclone separator apparatus, the distributor device comprising: a main body having a distribution chamber therein and comprising: a back wall having a back wall inner face; a front wall having a front wall inner face, wherein the back wall and the front wall at least in part enclose the distribution chamber, and a peripheral region positioned between and surrounding the front wall and the back wall to define a side wall at the peripheral region; a plurality of delivery outlets positioned adjacent to both the front wall and the back wall and arranged in spaced apart relation along the side wall of the peripheral region to deliver fluid to a point at the peripheral region of the distributor device proximate the side wall, wherein the delivery outlets are formed in or connected to the side wall; a feed inlet to the distribution chamber in the front wall having a main axis extending in a direction between the front and back walls, wherein the back wall inner face includes a main face section and a protrusion which extends from the main face section towards the front wall inner face, wherein the feed inlet comprises an inlet passage which includes an outer section which is cylindrical in cross section and an inner section which is flared in a trumpet shape and outwardly in cross section from the outer section in the direction of the front wall, wherein the flared inner section is curved, wherein the flared inner section blends into the front wall inner face providing a continuous uninterrupted blended surface leading from the inlet passage to the delivery outlets, wherein the front wall inner face and the back wall inner face are substantially parallel in a region of the main face section of the back wall inner face.
