Abstract

A surge bin for continuously collecting material such as conditioned ash from a nearby, non-contiguous ash conditioning pug mill and loading a haulage vehicle. The conditioned ash surge bin comprises a collection bin having walls and a door assembly forming the floor for collecting the conditioned ash. A support frame supports the collection bin above the height of the haulage vehicle so that the door assembly can unload the material into the haulage vehicle. The door assembly has two plates slidably mounted on the collection bin for movement between open and closed positions In order to transport the ash conditioning surge bin between different locations, the support frame of the conditioning ash surge bin houses a plurality of hydraulic jacks which can raise and lower the conditioned ash surge bin so that the haulage vehicle, supporting a conditioned ash surge bin carrier frame, can transport the conditioned ash surge bin to a new loading site.

Claims

1. A conditioned ash surge bin for collecting conditioned ash from an ash conditioner and loading an ash haulage vehicle comprising:

a collection bin having side walls and a door assembly forming a floor for collecting conditioned ash from the ash conditioner;

a support frame rigidly attached to the collection bin for supporting the collection bin above the ash haulage vehicle so that the door assembly can unload the conditioned ash into the ash haulage vehicle;

the door assembly comprising a pair of door plates slidably engaging the walls of the collection bin; and

means for opening and closing the door assembly comprising a cylinder having two ends, each end rigidly attached to one of the door plates so that the door plates are opened and closed in response to the extension and retraction of the cylinder.

2. The conditioned ash surge bin according to claim 1 wherein the door plates are positioned in the open position when the cylinder is extended and the door plates are positioned in the closed position when the cylinder is retracted.

3. The conditioned ash surge bin according to claim 2 wherein the door assembly further comprises a chain assembly for insuring that the door plates slide between the open and closed positions in unison.

4. The conditioned ash surge bin according to claim 3 wherein the chain assembly comprises two chains, each chain having a first end connected to one of the door plates and a second end connected to the other door plate.

5. The conditioned ash surge bin according to claim 1 wherein the support frame has a base housing a plurality of jacks which can raise and lower the surge bin to permit the ash haulage vehicle to be positioned underneath the support frame and carry the surge bin to a desired position.

6. The conditioned ash surge bin according to claim 5 wherein the volumetric capacity of the surge bin is about 90% of the volumetric capacity of the haulage vehicle.

7. The conditioned ash surge bin according to claim 1 wherein at least one of the walls has a negative taper to prevent the conditioned ash from hanging up on the walls.

8. A method for disposing of conditioned ash comprising:

transporting the ash to an ash conditioner for conditioning the ash to form conditioned ash having the proper characteristics for disposal,

transporting the conditioned ash to a conditioned ash surge bin for collecting and holding the conditioned ash, the conditioned ash surge bin comprising a collection bin having walls, a door assembly forming a floor, and a support frame for supporting the collection bin above an ash haulage vehicle,

positioning the ash haulage vehicle beneath the door assembly of the collection bin,

opening the door assembly to unload the conditioned ash from the conditioned ash surge bin and to load the ash haulage vehicle, and

transporting the conditioned ash in the ash haulage vehicle to an ash disposal site for disposal.

9. The method according to claim 8 comprising closing the door to collect conditioned ash.

10. The method according to claim 9 wherein the volumetric capacity of the surge bin is about 90% of the volumetric capacity of the haulage vehicle.

11. The method according to claim 8 comprising continuously transporting conditioned ash to the surge bin.

12. A surge bin for collecting material and loading a haulage vehicle for collecting and hauling material comprising:

a collection bin having side walls and a door assembly forming a floor for collecting material;

a support frame rigidly attached to the collection bin for supporting the collection bin above the haulage vehicle so that the door assembly can unload the material into the haulage vehicle;

the door assembly comprising a pair of door plates slidably engaging the collection bin; and

means for opening and closing the door assembly comprising a cylinder having two ends, each end rigidly attached to one of the door plates so that the door plates are opened and closed in response to the extension and retraction of the cylinders.

13. The surge bin according to claim 12 wherein the door plates are positioned in the open position when the cylinder is extended and the door plates are positioned in the closed position when the cylinder is retracted.

14. The surge bin according to claim 13 wherein the door assembly further comprises a chain assembly for insuring that the door plates slide between the open and closed positions in unison.

15. The surge bin according to claim 14 wherein the chain assembly comprises two chains, each chain having a first end connected to one of the door plates and a second end connected to the other door plate.

16. The surge bin according to claim 12 wherein the support frame has a base housing a plurality of jacks which can raise and lower the surge bin to permit the haulage vehicle to be positioned underneath the support frame and carry the surge bin to a desired position.

17. The surge bin according to claim 12 wherein at least one of the walls has a negative taper to prevent the material from hanging up on the walls.
