Patent ID: 7438803

Claim:
A particulate settling/filtration system for a machine tool comprising: a settling tank, said settling tank having four walls and a bottom yielding a given volume in which a slurry of fluid and particulate matter from said machine tool is transported into, said settling tank having an input and an output on opposing walls proximate the top of the tank; a removable, liner, said liner being permeable and comprising four walls and a base yielding dimensions complementary to said settling tank so as said liner will be received within said settling tank, said liner further comprising an input aperture aligning with said input of said settling tank, and an output aligning with said output of said settling tank, a plurality of vertically oriented baffles attached within said liner, interconnecting opposing walls perpendicular to the walls comprising the input aperture and the output aperture, so as they are positioned perpendicular to the flow of fluid through the liner from said input aperture to said output aperture, said baffles are alternately staggered vertically from the top of the liner to the bottom of the liner so as to force the flow of slurry to travel under a first baffle, over a second baffle and under a third baffle prior to exiting through said output aperture; wherein when said slurry travels through said liner, the flow is decreased to a rate wherein the majority of the particulate matter settles out by means of gravity to the bottom of the liner, and the fluid travels out through said output aperture.
