Abstract

A separator comprises a housing and a separator chamber contained within the housing, an inlet and outlet to the separator chamber and a dividing member for substantially dividing the separator chamber into a first chamber and a second chamber. A flow path is provided between the first and second chambers for allowing flow to circulate between the first and second chambers, and guide means for creating opposing flow paths in the second chamber for slowing flow through the second chamber.

First claim

What is claimed is:

1. A magnetic separator for separating particles from central heating system water, the separator comprising a housing, a separator chamber contained within the housing, an inlet and outlet to the separator chamber, a dividing member substantially dividing the separator chamber into a first chamber and a second chamber, a magnet provided in the first chamber, a flow path provided between the first and second chambers for allowing flow to circulate between the first and second chambers, and a flow guide disposed in the flow path between the first chamber and the second chamber for creating opposing flow paths in the second chamber from flow entering the second chamber via the flow guide, the opposing flow paths including a first flow portion flowing in a first direction and a second flow portion flowing in a second direction opposite the first direction, the opposing flow paths meeting in an area of the second chamber where the flow in each flow path is substantially towards opposing flow in the other flow path for slowing flow through the second chamber.

2. The separator of claim 1 , in which a tubular sleeve is provided around the magnet.

3. The separator of claim 2 , in which the tubular sleeve is mounted to the dividing member and extends longitudinally along a central axis of the first chamber.

4. The separator of claim 3 , in which the dividing member and tubular sleeve are removable for cleaning.

5. The separator of claim 1 , in which co-operating locating formations are provided on the dividing member and housing respectively, for positioning the dividing member within the housing.

6. The separator of claim 1 , in which an aperture is provided through the dividing member and a flow guide is positioned adjacent the aperture for directing flow through the aperture from the first chamber to the second chamber.

7. The separator of claim 6 , in which the aperture is a substantially radial slot.

8. The separator of claim 6 , in which a guide wall is provided in the second chamber for directing flow entering the lower portion through the aperture in the dividing member.

9. The separator of claim 8 , in which a space is provided between the upper end of the guide wall and the underside of the dividing member, in use, flow passing in one direction over the top of the wall and being directed in the opposite direction by the wall.

10. The separator of claim 6 , in which at least a second aperture is provided through the dividing member, the second aperture being around 120 degrees angularly displaced from the first aperture, behind the flow guide.

11. The separator of claim 10 , in which the second aperture is smaller than the first aperture.

12. The separator of claim 1 , in which arrestor elements are provided in the second chamber for slowing flow.

13. The separator of claim 12 , in which the arrestor elements include a plurality of pins.

14. The separator of claim 13 , in which the pins extend parallel with a central longitudinal axis of the separator.

15. The separator of claim 12 , in which the arrestor elements include one or more walls.

16. The separator of claim 15 , in which the arrestor elements further include a plurality of pins and in which the one or more walls extend from one of the pins.

17. The separator of claim 1 , in which a bleed valve for releasing pressure from the separator and a dosing point for adding liquid to the separator are provided in a single fitting.

18. The separator of claim 1 , in which flow in the first chamber is substantially unrestricted.

19. A magnetic separator for separating particles from central heating system water, the separator comprising a housing, a separator chamber contained within the housing, an inlet and outlet to the separator chamber, a dividing member substantially dividing the separator chamber into a first chamber and a second chamber, a flow path provided between the first and second chambers for allowing flow to circulate between the first and second chambers, and a flow guide disposed in the flow path between the first chamber and the second chamber for creating opposing flow paths in the second chamber from flow entering the second chamber via the flow guide, the flow guide including a reversing portion adapted to change the direction of a portion of the flow entering the second chamber and impinging on the flow guide for providing a first flow portion flowing in a first direction within the second chamber, and a bypass portion allowing passage past the flow guide of a further portion of the flow entering the second chamber, without change of direction of the further portion for providing a second flow portion flowing in a second direction opposite the first direction within the second chamber, the second chamber configured wherein the first flow portion and the second flow portion flow away from the flow guide and then against each other for slowing the flow through the second chamber.

20. A separator comprising a housing, a separator chamber contained within the housing, a dividing member substantially dividing the separator chamber into a first chamber and a second chamber, an inlet and outlet to the first chamber, a flow path provided between the first and second chambers for allowing flow to circulate from the first chamber to the second chamber and from the second chamber to the first chamber, and a flow guide for creating opposing flow paths in the second chamber by directing a portion of the flow into the second chamber and directing the flow in the second chamber against itself, the opposing flow paths meeting in an area of the second chamber where the flow in each path is substantially towards opposing flow in the other path for slowing flow through the second chamber, wherein flow in the first chamber between the inlet and the outlet thereof is substantially unrestricted.
