Particulate pump with rotary drive and integral chain

1. A particulate pump comprising:

a posimetric rotary drive including a hub affixed to a pair of discs, wherein the posimetric rotary drive provides a working surface for a coal plug against a wall;

a chain having a plurality of overlapping links, the chain integral with the hub; and

wherein the hub is affixed with a linear load beam and where the linear load beam includes a track guiding movement of the chain.

2. The particulate pump as recited in claim 1 , wherein the hub supports the chain.

3. The particulate pump as recited in claim 1 , wherein the discs are spaced apart and provide a passage there between, and the chain extends through the passage.

4. The particulate pump as recited in claim 1 , wherein the hub includes a track guiding movement of the chain.

5. The particulate pump as recited in claim 1 , where the chain is an endless chain.

6. The particulate pump as recited in claim 1 , where the chain is segmented.

7. The particulate pump as recited in claim 1 , where the posimetric rotary drive includes another hub spaced apart from the hub that is affixed to a pair of discs.

8. A particulate pump including:

a posimetric rotary drive including a hub affixed to a pair of discs, wherein the posimetric rotary drive provides a working surface for a coal plug against a wall;

a chain having a plurality of overlapping links, the chain integral with the hub; and

a scraper adjacent a periphery of the discs.

9. The particulate pump as recited in claim 8 , wherein the hub is affixed with a linear load beam.

10. The particulate pump as recited in claim 9 , where the linear load beam includes a track guiding movement of the chain.

11. The particulate pump as recited in claim 8 , wherein the scraper includes an end that may be radially aligned with the periphery of the discs.

12. The particulate pump as recited in claim 8 , wherein the hub supports the chain.

13. The particulate pump as recited in claim 8 , wherein the discs are spaced apart and provide a passage there between, and the chain extends through the passage.

14. The particulate pump as recited in claim 8 , wherein the hub includes a track guiding movement of the chain.

15. The particulate pump as recited in claim 8 , where the chain is an endless, segmented chain.

16. The particulate pump as recited in claim 8 , wherein the posimetric rotary drive includes another hub spaced apart from the hub that is affixed to a pair of discs.

17. A method for use with a particulate pump, the method comprising:

providing a coal plug in a posimetric rotary drive that includes a hub affixed to a pair of discs, wherein the posimetric rotary drive provides a working surface for the coal plug against a wall;

moving a chain to move the coal plug through the posimetric rotary drive, the chain includes a plurality of overlapping links and is integral with the hub; and

moving the coal plug across a scraper adjacent a periphery of the discs.

18. The method as recited in claim 17 , including guiding the chain with tracks in the hub.

19. The method as recited in claim 17 , including moving the chain using a drive sprocket.

20. A particulate pump comprising:

a posimetric rotary drive including a hub affixed to a pair of discs, wherein the posimetric rotary drive provides a working surface for a coal plug against a wall;

a chain having a plurality of overlapping links, the chain integral with the hub; and

wherein the posimetric rotary drive includes another hub spaced apart from the hub that is affixed to a pair of discs.

21. The particulate pump as recited in claim 20 , wherein the hub supports the chain.

22. The particulate pump as recited in claim 20 , wherein the discs are spaced apart and provide a passage there between, and the chain extends through the passage.

23. The particulate pump as recited in claim 20 , wherein the hub includes a track guiding movement of the chain.

24. The particulate pump as recited in claim 20 , where the chain is an endless, segmented chain.
