Abstract

An automatically adjustable abrasive recycling system is provided. The abrasive recycling system includes one or more sensors configured to sense at least one characteristic of the abrasive recycling system, and slurry supply mechanism that operates, at least in part, based upon the sensed characteristic to control the operation of the abrasive recycling system. The abrasive recycling system further includes a substantially vertically arranged configuration of component parts. Methodology corresponding to the automatic operation of the abrasive recycling system is also provided.

First claim

What is claimed is:

1. A liquid jet abrasive recycling system, the system comprising:
a frame having a base structure that contacts a surface on which the system rests, wherein peripheral-most portions of the base structure that contacts the surface define a footprint perimeter of the system;
a slurry inlet supported by the frame, the slurry inlet configured to receive a slurry, the slurry containing a liquid, foreign particles, and an abrasive;
a dryer supported by the frame and configured to receive the slurry and remove the liquid therefrom to form a dry mixture;
an outlet in communication with the dryer to receive the dry mixture, an egress of the outlet being disposed in the footprint perimeter; and
an abrasive collector in communication with the outlet, the abrasive collector configured to collect the abrasive as it is released from the egress and within the footprint perimeter, wherein the abrasive collector is positioned within the footprint perimeter.

2. The system of claim 1 , wherein the slurry inlet, the dryer, and the outlet are positioned within the footprint perimeter.

3. The system of claim 1 , further comprising a screening assembly to filter the abrasive and the foreign particles from one another.

4. The system of claim 3 , wherein the outlet comprises the screening assembly.

5. The system of claim 1 , wherein the frame defines an abrasive collection region that is disposed vertically below the screening assembly and that is configured to receive the abrasive as it is released from the egress and within the footprint perimeter, and wherein the abrasive collector is removably positioned within the abrasive collection region.

6. The system of claim 1 , further comprising a pump in operative communication between a liquid jet cutting table and the slurry inlet, the pump configured to provide the slurry to the slurry inlet, the pump being supported by the frame and being positioned within the footprint perimeter.

7. The system of claim 1 , further comprising a sensor positioned within the footprint perimeter and in operative communication with the abrasive collector, wherein the sensor measures a characteristic of the abrasive when the abrasive is disposed within the abrasive collector.

8. The system of claim 7 , wherein the sensor comprises a load cell that measures a weight of the abrasive when the abrasive is in the abrasive collector.

9. The system of claim 7 , wherein the system automatically adjusts operation based on the characteristic of the abrasive when the abrasive is sensed by the sensor.

10. A liquid jet abrasive recycling system, the system comprising:
a frame having a base structure that contacts a surface on which the system stands, wherein peripheral-most portions of the base structure that contacts the surface on which the system stands define a footprint perimeter of the system, and wherein an axis that is substantially vertically oriented is centrally positioned within the footprint perimeter;
a slurry inlet functionally coupled to the frame and configured to receive a slurry, the slurry containing liquid, abrasive, and foreign particles;
a screening assembly functionally coupled to the frame and configured to separate the abrasive from the foreign particles;
a dryer functionally coupled to the frame and configured to remove the liquid; and
an abrasive collector positioned within the frame and configured to collect the abrasive, wherein a portion of the abrasive collector, which is configured to receive the abrasive after the abrasive is separated from the foreign particles, intersects the axis.

11. The system of claim 10 , wherein the screening assembly receives the slurry from the slurry inlet and filters the foreign particles from the slurry before passing the slurry to the dryer.

12. The system of claim 10 , wherein the dryer receives the slurry from the slurry inlet and removes the liquid therefrom before passing a dried mixture of the foreign particles and the abrasive to the screening assembly.

13. The system of claim 10 , wherein the portions of each of the slurry inlet and the screening assembly intersect the axis.

14. The system of claim 10 , wherein the dryer has a length and is arranged proximate one of the slurry inlet and the screening assembly, the length of the dryer being arranged in a substantially parallel orientation with the axis.

15. The system of claim 10 , further comprising a pump in operative communication between a liquid jet cutting table and the slurry inlet, the pump configured to provide the slurry to the slurry inlet, the pump being positioned substantially vertically below the dryer.

16. The system of claim 10 , further comprising a sensor in operative communication with the abrasive collector, wherein the sensor measures a characteristic of the abrasive when the abrasive is disposed in the abrasive collector.

17. The system of claim 16 , wherein the sensor comprises a load cell that measures a weight of the abrasive in the abrasive collector, and wherein the system automatically adjusts operation based on the weight of the abrasive sensed by the sensor.

18. A method of recycling a liquid jet abrasive, the method comprising:
coupling a slurry inlet to a frame having a base structure that contacts a surface on which the system rests, wherein peripheral-most-portions of the base structure that contacts the surface define a footprint perimeter of the system;
providing a slurry to the slurry inlet;
filtering foreign particles from the slurry in a screening assembly;
drying the filtered slurry from the filtering step in a dryer to remove liquid therefrom and to form a substantially dry mixture; and
collecting an abrasive material from the substantially dry mixture in an abrasive collector as the abrasive material is released within the footprint perimeter,
wherein the slurry inlet, the dryer, the screening assembly, and the abrasive collector are positioned within the footprint perimeter.

19. The method of claim 18 , further comprising pumping the slurry to the slurry inlet by a pump, wherein the pump is positioned within the footprint perimeter.

20. The system of claim 18 , further comprising sensing a characteristic of the abrasive material by a sensor when the abrasive material is disposed in the abrasive collector, wherein the sensor is positioned within the footprint perimeter.
