Rotary disc type diverter valve for bulk material handling

1. A diverter valve for use in directing a flow of particulate bulk material from a source to at least one receptacle, comprising:

an inlet housing with a frusto-conical shape and having an inlet port and partially defining a valve chamber;

a generally planar outlet housing connected to said inlet housing, having at least one outlet port and defining an end of said valve chamber, said at least one outlet port and said inlet port being generally aligned along a common horizontal axis; and

a rotating planar disc rotatably disposed in said chamber closer to said at least one outlet port than to said inlet port and constructed and arranged for selectively creating fluid communication between said inlet port and diverting the flow of particulate material to a selected one of said at least one outlet port.

2. The diverter valve of claim 1 wherein said inlet housing is configured for receiving and retaining a portion of the flow so that the bulk material passes autogenously through said chamber.

3. The diverter valve of claim 1 further including at least one seal disposed in operational relationship to each said outlet port to prevent leakage of the material.

4. The diverter valve of claim 3 wherein each said at least one seal is located between said rotating disc and said outlet housing.

5. The diverter valve of claim 4 wherein said rotating disc has an inlet surface, an opposite outlet surface slidingly engaging an inner surface of said outlet housing, and each said at least one seal is located between said outlet surface and said inner surface for contacting said rotating disc.

6. The diverter valve of claim 1 further including one or more outlet pipes each connected to said outlet housing and having a first end connected to said outlet housing and an opposite second end connected to the at least one receptacle, said first end having a plurality of peripherally spaced lugs each constructed and arranged to engage a corresponding notch in said outlet housing.

7. The diverter valve of claim 1 further including one or more outlet pipes each connected to said outlet housing and having a first end connected to said outlet housing and an opposite second end connected to the at least one receptacle, said first end connected to said outlet housing to form a mating engagement.

8. The diverter valve of claim 7 , wherein said mating engagement is achieved by providing a plurality of peripherally spaced lugs on one of said first end and said outlet housing, and a like plurality of peripherally spaced notches on the other of said first end and said outlet housing.

9. The diverter valve of claim 1 , wherein said rotating disc has an inlet surface, an opposite outlet surface engaging an inner surface of said outlet housing and an opening allowing for the flow to pass through to a selected one of said at least one outlet ports, said opening being radially displaced between an axis of said disc and a peripheral edge of said disc, an inflatable seal being disposed between said opening and said outlet housing for controlling the flow to said one of at least one outlet ports.

10. The diverter valve of claim 9 , wherein said rotating disc is provided with an axially projecting shaft extending from an outlet surface towards said outlet housing.

11. The diverter valve of claim 10 , further including at least one bearing in said outlet housing constructed and arranged for rotatably accommodating said shaft.

12. The diverter valve of claim 1 , wherein said valve chamber is defined in part by an inclined wall of said inlet housing that is constructed and arranged to receive a supply of the bulk material to coat an inner surface of said valve chamber, allowing for resistance to abrasive wear.

13. The diverter valve of claim 1 , wherein said inlet port is generally horizontally aligned with said at least one outlet port.

14. The diverter valve of claim 1 , wherein said inlet housing has a flange axially projecting from said housing for engaging a corresponding peripheral edge of said outlet housing.

15. The diverter valve of claim 1 , further including a power source connected to said rotating disc for rotating said disc for selectively aligning an opening in said disc with a selected one of said outlet ports.

16. A diverter valve for use in directing a flow of particulate bulk material from a source to at least one receptacle, comprising:

an inlet housing having an inlet port and partially defining a valve chamber;

a generally planar outlet housing connected to said inlet housing, having a plurality of outlet ports and defining an end of said valve chamber;

a rotating planar disc rotatably disposed in said chamber closer to said outlet ports than to said inlet ports and having a single aperture constructed and arranged for selectively creating fluid communication between said inlet port and diverting the flow of particulate material to a selected one of said plurality of outlet ports;

said inlet port said at least one outlet port being generally aligned along a common horizontal axis;

said rotating disc has an inlet surface, an opposite outlet surface engaging an inner surface of said outlet housing and an opening allowing for the flow to pass through to a selected one of said at least one outlet ports, said opening being radially displaced between an axis of said disc and a peripheral edge of said disc, an inflatable seal being disposed between said opening and said outlet housing for controlling the flow to said one of at least one outlet ports, said rotating disc has an inlet surface, an opposite outlet surface slidingly engaging an inner surface of said outlet housing, and each said seal is located between said outlet surface and said inner surface for contacting said rotating disc;

said rotating disc has a single opening allowing for the flow to pass through to a selected one of said outlet ports; and

said rotating disc is provided with an axially projecting shaft extending from an outlet surface towards said outlet housing.
