Abstract

A closing valve unit for a centrifugal cleaner arrangement including first and second connecting members configured to connect a cyclone to a centrifugal cleaner group, and a movable valve sandwiched between the first and second connecting members, the moveable valve including apertures commensurate with openings to feed and reject conduits of the cyclone and to openings to feed and reject conduits of the cyclone cleaner group, wherein the movable valve has a first position in which the apertures are aligned with the cyclone and cleaner group feed conduits and with the cyclone accept and cleaner group accept conduits, and a control element connected to the moveable valve and configured to move the moveable valve between the first position and the second positions.

First claim

The invention claimed is:

1. A valve assembly for a centrifugal cleaner arrangement comprising:
a first connecting member configured to connect to a cyclone feed conduit and a cyclone accept conduit of a cyclone;
a second connecting member configured to connect to a cleaner group feed conduit of a centrifugal cleaner group and an accept conduit of the centrifugal cleaner group;
a movable valve including first and second apertures and the movable valve is sandwiched between the first and second connecting members, wherein the movable valve has a first position in which the first aperture is aligned with an opening to the cyclone feed conduit and to an opening to the cleaner group feed conduit and the first aperture provides a passage for fluid flow between the cyclone feed conduit and the cleaner group feed conduit, and the second aperture is aligned with an opening to the cyclone accept conduit and to an opening to the cleaner group accept conduit and the second aperture provides a passage for flow between the cyclone accept conduit and the cleaner group accept conduit,
wherein in the first position the opening to the cyclone feed conduit is coaxial with an axis of the cyclone feed conduit and the opening to the cyclone accept conduit is coaxial with an axis of the cyclone accept conduit;
the movable valve has a second position in which a solid portion of the movable valve entirely blocks the opening to the cyclone feed conduit and entirely blocks the opening to the cyclone accept conduit, and
a control element connected to the moveable valve and configured to move the moveable valve between the first position and the second position.

2. The valve assembly of claim 1 wherein the axis of the cyclone feed conduit is coaxial with an axis of the first aperture and is coaxial with an axis of the cleaner group feed conduit while the movable valve is in the first position.

3. The valve assembly of claim 1 wherein the first connecting member includes a first bracket and the second connecting member includes a second bracket complementary to the first bracket, wherein the movable valve slides within and between the first and second brackets.

4. The valve assembly of claim 3 wherein the moveable valve is a circular plate and rotates between the first and second positions.

5. The valve assembly of claim 3 wherein the movable valve is a rectangular plate and slides between the first and second positions.

6. The valve assembly of claim 1 wherein the first aperture is congruent with the opening to the cyclone feed conduit and the opening to the cleaner group feed conduit, and the second aperture is congruent with the opening to the cyclone accept conduit and the opening to the cleaner group accept conduit.

7. The valve assembly of claim 1 wherein the axis of the cyclone feed conduit is parallel to the axis of the cyclone reject conduit.

8. A centrifugal cleaner arrangement comprising:
a cyclone including a cyclone feed conduit and a cyclone accept conduit; a centrifugal cleaner group including a cleaner group feed conduit and a cleaner group accept conduit;
a closing valve unit connecting the cyclone feed and accept conduits to the cleaner group feed and accept conduits, the closing valve unit including a first connecting member, a second connecting member and a movable valve sandwiched between the first and second connecting members;
the second connecting member is configured to connect to a cleaner group feed conduit of a centrifugal cleaner group and an accept conduit of the centrifugal cleaner group;
the moveable valve including a first aperture commensurate with an opening to the cyclone feed conduit and an opening to the cleaner group feed conduit, and a second aperture commensurate with an opening to the cyclone accept conduit and an opening to the cleaner group accept conduit,
wherein the movable valve has a first position in which the first aperture is aligned with the cyclone feed conduit and the cleaner group feed conduit and the first aperture provides a passage for fluid communication between the cyclone feed conduit and the cleaner group feed conduit, and the second aperture is aligned with the cyclone accept conduit and the cleaner group accept conduit and the second aperture provides a passage for fluid communication between the cyclone accept conduit and the cleaner group accept conduit,
wherein in the first position the opening to the cyclone feed conduit is coaxial with an axis of the cyclone feed conduit and the opening to the cyclone accept conduit is coaxial with an axis of the cyclone accept conduit;
the movable valve has a second position in which a solid portion of the movable valve entirely blocks the opening to the cyclone feed conduit and entirely blocks the opening to the cyclone accept conduit,
and a control element connected to the moveable valve and configured to move the moveable valve between the first position and the second position.

9. The centrifugal cleaner arrangement of claim 8 wherein the axis of the cyclone feed conduit is coaxial with an axis of the first aperture and is coaxial with an axis of the cleaner group feed conduit while the movable valve is in the first position.

10. The centrifugal cleaner arrangement of claim 8 wherein the first connecting member includes a first bracket and the second connecting member includes a second bracket complementary to the first bracket, wherein the movable valve slides within and between the first and second brackets.

11. The centrifugal cleaner arrangement of claim 8 wherein the moveable valve is a circular plate and rotates between the first and second positions.

12. The centrifugal cleaner arrangement of claim 8 wherein the movable valve is a rectangular plate and slides between the first and second positions.

13. The centrifugal cleaner arrangement of claim 8 wherein the first aperture is congruent with the opening to the cyclone feed conduit and the opening to the cleaner group feed conduit, and the second aperture is congruent with the opening to the cyclone accept conduit and the opening to the cleaner group accept conduit.
