Abstract

A separator (10) comprises a housing (12) and a separator chamber (14) contained within the housing (12), an inlet (16) and outlet (18) to the separator chamber and a dividing member (20) for substantially dividing the separator chamber (14) into a first chamber (22) and a second chamber (24). A flow path is provided between the first and second chambers (22), (24) for allowing flow to circulate between the first and second chambers, and obstruction means (74) is provided in the second chamber (24) for slowing flow through the second chamber (24).

Claims

1. A separator comprising a housing, a separator chamber contained within the housing, a dividing member for 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 between the first and second chambers, guide means for guiding only a portion of the flow from the inlet through the second chamber, and obstruction means provided in the second chamber for slowing flow through the second chamber, the second chamber being in fluid communication with the inlet and outlet only via the first chamber.

2. A separator as claimed in claim 1, in which the housing includes a body portion and a removable closure portion, the removable closure portion being screw threaded into the body portion.

4. A separator as claimed in claim 1, in which the second chamber includes a tray having a base and at least one sidewall for collecting sediment.

5. A separator as claimed in claim 4, in which the dividing member adjoins and is releasably connected to the tray.

6. A separator as claimed in claim 5, in which the dividing member is connected to the tray by means of a bayonet fixing.

7. A separator as claimed in claim 6, in which a magnet is provided in the first chamber.

8. A separator as claimed in claim 7, in which a tubular sleeve is provided around the magnet.

9. A separator as claimed in claim 8, in which the tubular sleeve is mounted to the dividing member and extends longitudinally along a central axis of the first chamber.

10. A separator as claimed in claim 9, in which a substantially conical deflector is mounted at the upper end of the first chamber for accelerating flow in the upper part of the chamber.

11. A separator as claimed in claim 10, in which the conical deflector is mounted to the tubular sleeve.

12. A separator as claimed in claim 11, in which the tray, separation member, tubular sleeve and substantially conical deflector are removable for cleaning

13. A separator as claimed in claim 1, in which a bleed valve is provided for bleeding air from the separator.

14. A separator as claimed in claim 1, in which a dosing point is provided for adding liquid to the separator.

16. A separator as claimed in claim 4, in which the obstruction means includes a plurality of pins.

17. A separator as claimed in claim 16, in which at least one of the pins extends through an aperture in the dividing member into the first chamber.

18. A separator as claimed in claim 17, in which the pins extend perpendicularly from the base of the tray and are cylindrical or substantially conical.

19. A separator as claimed in claim 18, in which at least one of the pins is cut away on one side to present a flat surface to flow through the inlet.

20. A separator as claimed in claim 1, in which the obstruction means includes a plurality of radial walls.

21. A separator as claimed in claim 1, in which a plurality of radial walls are provided on the dividing member and extend into the first chamber.

22. A separator as claimed in claim 21, in which an aperture is provided through the dividing member at the base of at least one of the radial walls, the radial wall guiding flow through the aperture.
