Abstract

A separator device for removing particles from suspension in a liquid includes a housing having first and second chambers with apertures for ingress and egress of liquid into the first chamber. Means are provided for setting up a swirl of liquid within the first chamber. Apertures enable flow of liquid between the first chamber and the second chamber. Means are also provided for setting up a swirl of liquid within the second chamber. The swirl in the second chamber is in substantially the opposite direction to the swirl in the first chamber, and there is no substantial flow in the second chamber which is in the same direction as the swirl in the first chamber.

First claim

The invention claimed is:

1. A separator device for removing particles from suspension in a liquid comprising:
a housing, having a first chamber and a second chamber, baffles being provided in the second chamber to slow the flow of liquid within the second chamber for separating small solid particles from the liquid, wherein the second chamber is a separation chamber;
apertures formed in a portion of the housing defining the first chamber, the apertures allowing ingress of liquid into the first chamber and egress of liquid out of the first chamber;
means for setting up a swirl of liquid within the first chamber; apertures enabling flow of liquid from the first chamber to the second chamber and from the second chamber to the first chamber; and
means for directing a flow of liquid within the second chamber, the flow in the second chamber being in substantially the opposite direction to the swirl in the first chamber.

2. The separator device of claim 1 , wherein the apertures formed in the portion of the housing defining the first chamber form an inlet and an outlet to the first chamber, wherein flow in the first chamber between the inlet and outlet is substantially unobstructed.

3. The separator device of claim 1 , in which the means for directing a flow of liquid within the second chamber sets up a swirl of liquid in the second chamber.

4. The separator device of claim 1 , in which a third chamber is provided in the housing, the third chamber being apertured for ingress and egress of fluid from at least one of the first chamber and the second chamber, and means being provided for directing a flow of liquid in the third chamber.

5. The separator device of claim 4 , in which the means for directing a flow of liquid in the third chamber sets up a swirl of liquid in the third chamber.

6. The separator device of claim 4 , in which the means for directing a flow of liquid in the third chamber causes liquid to flow in the same direction as the flow in the second chamber.

7. The separator device of claim 4 , in which the first chamber is disposed between the second and third chambers.

8. The separator device of claim 4 , in which the first, second, and third chambers share a single central axis.

9. The separator device of claim 8 , in which the means for directing flow of liquid within the second chamber comprise apertures in the chamber having the form of curved slots.

10. The separator device of claim 1 , in which the means for directing a flow of liquid in the second chamber reverses the direction of liquid flow upon entry to the second chamber.

11. The separator device of claim 1 , in which the means for directing flow of liquid within the second chamber comprise of at least one flow guide extending from a wall of the chamber adjacent to at least one aperture in the chamber wall.

12. The separator device of claim 11 , in which the flow guide or flow guides form an angled deflector overhanging each aperture.

13. The separator device of claim 11 , in which the flow guide or flow guides extend below the aperture wall, into the chamber in which flow is being directed.

14. The separator device of claim 1 , in which the means for directing a flow of liquid within the second chamber sets up flows of liquid in opposing directions.

15. A separator device for removing particles from suspension in a liquid comprising:
a housing, having a first chamber and a second chamber, wherein the second chamber is a separation chamber;
apertures formed in a portion of the housing defining the first chamber, the apertures for allowing ingress of liquid into the first chamber and egress of liquid out of the first chamber;
means for setting up a swirl of liquid within the first chamber; and
apertures enabling flow of liquid from the first chamber to the second chamber and from the second chamber to the first chamber;
the direction of liquid flow being substantially reversed as liquid enters the second chamber, and at least a portion of flow being substantially reversed again within the second chamber.

16. The separator device of claim 15 , in which a third chamber is provided, being apertured for ingress and egress of fluid from at least one of the first chamber and the second chamber, and means being provided for setting up a swirl of liquid in the third chamber.

17. The separator device of claim 16 , in which the first chamber is disposed between the second and third chambers.

18. The separator device of claim 16 , in which the means for setting up a swirl of liquid within at least one of the second chamber and the third chamber comprise apertures in the chamber having the form of curved slots.

19. The separator device of claim 15 , in which the means for setting up a swirl of liquid within the second chamber comprise at least one flow guide extending from a wall of the chamber adjacent to at least one aperture in the chamber wall.

20. The separator device of claim 19 , in which the flow guide or guides form an angled deflector overhanging each aperture.

21. The separator device of claim 19 , in which opposing swirls of liquid are set up in the second chamber.
