Abstract

A pump apparatus includes a particulate pump that defines a passage that extends from an inlet to an outlet. A duct is in flow communication with the outlet. The duct includes a deconsolidator configured to fragment particle agglomerates received from the passage.

Claims (16)

1. A pump apparatus comprising:

a particulate pump defining a passage extending from an inlet to an outlet; and

a duct in flow communication with the outlet, the duct including a deconsolidator configured to fragment particle agglomerates received from the passage, the deconsolidator including a divider splitting the duct into multiple passages leading to corresponding ones of multiple duct outlets from the deconsolidator.

2. The pump apparatus as recited in claim 1 , wherein the duct is connected at the outlet of the passage.

3. The pump apparatus as recited in claim 1 , wherein the duct includes multiple moveable doors arranged, respectively, at the multiple duct outlets, the multiple moveable doors having open and closed positions with respect to the multiple duct outlets.

4. The pump apparatus as recited in claim 3 , wherein the multiple movable doors are biased toward the closed positions.

5. The pump apparatus as recited in claim 3 , wherein the multiple movable doors are movable in response to a pressure in the duct exceeding a threshold.

6. The pump apparatus as recited in claim 3 , wherein the multiple movable doors are moveable by non-electronic actuation.

7. The pump apparatus as recited in claim 3 , wherein the multiple movable doors seal against the respective multiple duct outlets in the closed positions.

8. The pump apparatus as recited in claim 3 , wherein the multiple movable doors are linearly moveable.

9. The pump apparatus as recited in claim 3 , wherein the multiple movable doors are passively moveable between the open and closed positions by non-electronic actuation to control discharge from the multiple passages.

10. The pump apparatus as recited in claim 3 , wherein each of the multiple moveable doors includes a plate with guide bosses extending therefrom, and the guide bosses are slideably supported on respective struts.

11. The pump apparatus as recited in claim 10 , wherein the struts include bias members biasing toward the multiple moveable doors toward the closed positions.

12. The pump apparatus as recited in claim 1 , wherein the multiple passages turn laterally with respect to the passage of the particulate pump.

13. The pump apparatus as recited in claim 1 , wherein the multiple passages are laterally offset from each other.

14. The pump apparatus as recited in claim 1 , wherein the duct includes a hard-face coating.
