Dual Element Vacuum Filtration System For Metal-Working Fluids

US Patent:
2007011, May 24, 2007
Filed:
Oct 23, 2006
Appl. No.:
11/551738
Inventors:
James Lupien - Windham NH, US
Gregory Sorge - North Haven CT, US
International Classification:
B23Q 11/00
B01D 36/04
US Classification:
210298000
Abstract:
A filtration system for removing solid particles from a liquid that includes a liquid-containing tank and a spaced pair of filtration elements immersed in the liquid in the tank. Each filtration element is selectively connectable to a source of vacuum to draw liquid from the tank through a spaced pair of filter screens carried by the filtration element to filter out particles from the liquid, or, alternately, to a source of pressure to backwash the filter screens to clean collected particles therefrom. By providing a pair of filtration elements, one of any such elements can be kept operating in a filtration mode while the other is operating in a backwashing mode. An endless dragout conveyor is positioned in the tank beneath the filtration elements to collect and carry out particles that fall from or between the filtration units to an elevated external deposit location. Each filtration element has at least one filter screen, and preferably two or more spaced pairs of filtration screens.
