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 a floor with a drain; 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, wherein the first reservoir is configured to permit settlement of material entrained in the fluid prior to the fluid exceeding 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 a 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 , further comprising a removable lid shaped to conform to an opening in a ceiling of the first reservoir, the removable lid having a lid inlet configured for fluid communication with a cabinet outlet of a material removal cabinet housing the material removal machine, such that fluid can flow from the material removal cabinet to the first reservoir through the cabinet outlet and lid inlet.

7 . The recirculation system of claim 5 , wherein the lid inlet is out of alignment with the drain when the removable lid is fit into the opening in the ceiling of the first reservoir.

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

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

10 . The recirculation system of claim 1 , wherein the height of the standpipe is based on a first capacity of the first reservoir and a second capacity of the second reservoir.

11 . A material removal system, comprising:
a material removal cabinet housing a material removal machine; a recirculation system in fluid communication with the material removal cabinet, the recirculation system comprising:
a first reservoir having a floor with a drain;
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, wherein the first reservoir is configured to permit settlement of material entrained in the fluid prior to the fluid exceeding the first height.

12 . The material removal system of claim 11 , wherein the second reservoir is positioned below the drain of the first reservoir to receive the fluid falling through the drain.

13 . The material removal system of claim 11 , wherein the second reservoir is in fluid communication with the material removal cabinet housing the material removal machine.

14 . The material removal system of claim 13 , wherein the material removal machine comprises a sectioning saw.

15 . The material removal system of claim 13 , further comprising a recirculation pump configured to pump the fluid from the second reservoir to the material removal cabinet.

16 . The material removal system of claim 11 , further comprising a removable lid shaped to conform to an opening in a ceiling of the first reservoir, the removable lid having a lid inlet configured for fluid communication with a cabinet outlet of a material removal cabinet housing the material removal machine, such that fluid can flow from the material removal cabinet to the first reservoir through the cabinet outlet and lid inlet.

17 . The material removal system of claim 15 , wherein the lid inlet is out of alignment with the drain when the removable lid is fit into the opening in the ceiling of the first reservoir.

18 . The material removal system of claim 11 , wherein the first reservoir is smaller than the second reservoir.

19 . The material removal system of claim 11 , wherein the first reservoir and the second reservoir do not include either of a filter or filtration media.

20 . The material removal system of claim 11 , wherein the height of the standpipe is based on a first capacity of the first reservoir and a second capacity of the second reservoir.
