Abstract

Provided are a recirculation system ( 200 ) for a material removal machine ( 102 ) and a material removal system ( 100 ). A material removal system ( 100 ) includes a recirculation system ( 200 ) in fluid communication with a material removal cabinet ( 104 ) housing a material removal machine ( 102 ). The recirculation system ( 200 ) may have an upper reservoir ( 300 ) configured to drain fluid into a lower reservoir ( 204 ) before recirculating the fluid. The upper reservoir ( 300 ) may have a standpipe ( 320 ) configured to allow swarf, debris, and/or other material within the fluid to be entrained prior to flowing over the standpipe ( 320 ).

First claim

What is claimed is:

1. A recirculation system for a material removal machine, comprising:
a first reservoir having an opening and a floor with a drain;
a removable lid shaped to conform to the opening in the first reservoir, the removable lid having a lid inlet, such that fluid can flow into the first reservoir through the lid inlet from a cabinet outlet of a material removal cabinet housing the material removal machine;
a second reservoir in fluid communication with the first reservoir through the drain; and
a standpipe having walls that form a border around the drain within the first reservoir, the walls extending upwards away from the floor to a first height, such that fluid that accumulates on the floor within the first reservoir is blocked from flowing through the drain into the second reservoir until a top of the fluid in the first reservoir exceeds the first height.

2. The recirculation system of claim 1 , wherein the second reservoir is positioned below the drain of the first reservoir to receive the fluid falling through the drain.

3. The recirculation system of claim 1 , wherein the second reservoir is in fluid communication with the material removal cabinet housing the material removal machine.

4. The recirculation system of claim 3 , wherein the material removal machine comprises a sectioning saw.

5. The recirculation system of claim 3 , further comprising a recirculation pump configured to pump the fluid from the second reservoir to the material removal cabinet.

6. The recirculation system of claim 1 , wherein the opening is a first opening, the recirculation system further comprising a second lid shaped to conform to a second opening in the second reservoir, the second lid having a window sized to receive the first reservoir.

7. The recirculation system of claim 6 , further comprising a recirculation pump retained by the second lid.

8. The recirculation system of claim 1 , wherein the lid inlet is out of alignment with the drain when the removable lid is fit into the opening of the first reservoir.

9. The recirculation system of claim 1 , wherein the first reservoir is smaller than the second reservoir.

10. The recirculation system of claim 1 , wherein the first reservoir and the second reservoir do not include either of a filter or filtration media.

11. The material removal system of claim 1 , wherein the lid inlet is out of alignment with the drain when the removable lid is fit into the opening of the first reservoir.

12. A material removal system, comprising:
a material removal cabinet housing a material removal machine; and
a recirculation system in fluid communication with the material removal cabinet, the recirculation system comprising:
a first reservoir having a lid an opening and a floor with a drain,
a removable lid shaped to conform to the opening in the first reservoir, the removable lid having a lid inlet, such that fluid can flow into the first reservoir through the lid inlet from a cabinet outlet of the material removal cabinet housing the material removal machine,
a second reservoir in fluid communication with the first reservoir through the drain, and
a standpipe having walls that form a border around the drain within the first reservoir, the walls extending upwards away from the floor to a first height, such that fluid that accumulates on the floor within the first reservoir is blocked from flowing through the drain into the second reservoir until a top of the fluid in the first reservoir exceeds the first height.

13. The material removal system of claim 12 , wherein the second reservoir is positioned below the drain of the first reservoir to receive the fluid falling through the drain.

14. The material removal system of claim 12 , wherein the second reservoir is in fluid communication with the material removal cabinet housing the material removal machine.

15. The material removal system of claim 14 , wherein the material removal machine comprises a sectioning saw.

16. The material removal system of claim 14 , further comprising a recirculation pump configured to pump the fluid from the second reservoir to the material removal cabinet.

17. The material removal system of claim 12 , wherein the opening is a first opening, the recirculation system further comprising a second lid shaped to conform to a second opening in the second reservoir, the second lid having a window sized to receive the first reservoir.

18. The material removal system of claim 17 , further comprising a recirculation pump retained by the second lid.

19. The material removal system of claim 12 , wherein the first reservoir is smaller than the second reservoir.

20. The material removal system of claim 12 , wherein the first reservoir and the second reservoir do not include either of a filter or filtration media.
