Patent number: 7976704Abstract: A filtration device is provided with a filter tank, filter media unit, and magnet. The filter media unit includes a filter media accommodation case and a large number of magnetic granular filter media. The magnet is movable between first and second positions. In the first position, a magnetic field is applied to the magnetic granular filter media, so that the magnetic granular filter media magnetically attract one another. In the second position, magnetic attraction between the magnetic granular filter media is canceled. The filter media accommodation case includes a nonmagnetic mesh member of a nonmagnetic material and magnetism intensification plate of a magnetic material. When the magnet is in the first position, the magnetic granular filter media and nonmagnetic mesh member are located between the magnetism intensification plate and the magnet.Type: GrantFiled: May 15, 2009Date of Patent: July 12, 2011Assignee: Bunri IncorporationInventor: Minoru Tashiro

Publication number: 20110062064Abstract: A filtration device is provided with a filter tank, filter medium unit, magnet, and submerged air discharging mechanism. The filter medium unit includes a large number of magnetic filter medium granules formed of metal balls. When the magnet is in a first position, the magnetic filter medium granules magnetically attract one another. When the magnet is moved to a second position, the magnetic filter medium granules are released from the mutual magnetic attraction. In cleaning the magnetic filter medium granules, a clean fluid located above the magnetic filter medium granules is poured between the magnetic filter medium granules. In cleaning the magnetic filter medium granules, the submerged air discharging mechanism ejects air into the clean fluid above the magnetic filter medium granules and toward the magnetic filter medium granules. Air bubbles are introduced into the clean fluid by the ejected air.Type: ApplicationFiled: November 18, 2010Publication date: March 17, 2011Inventor: Minoru TASHIRO

Patent number: 7906021Abstract: A contaminated fluid recovery apparatus includes a dirty tank, a conveyor, and a drum-shaped filter unit. Inlet ports of the drum-shaped filter unit open along an axis of a magnet drum. The conveyor scrapes out an object for removal settled on a bottom portion of the dirty tank toward an exit section. The conveyor includes a lower portion which moves along the bottom portion and an upper portion which passes over the lower portion. The magnet drum is located horizontally between the lower portion and the upper portion of the conveyor so that its axis is perpendicular to a direction of travel of the conveyor. The magnet drum is driven by a chain of the conveyor.Type: GrantFiled: March 20, 2009Date of Patent: March 15, 2011Assignee: Bunri IncorporationInventor: Minoru Tashiro

Patent number: 7867388Abstract: A contaminated fluid recovery apparatus includes a sludge removal mechanism having a dirty tank, a conveyor, and a magnetic drum which is arranged in the fluid circulating section. The contaminated fluid recovery apparatus is provided with an overflow tank. The overflow tank has a function to keep a fluid surface of the dirty tank in a position higher than the fluid circulating section and the magnetic drum. The magnetic drum is located horizontally between a lower portion and an upper portion of the conveyor. The conveyor scrapes out chips deposited on a bottom portion of the dirty tank toward an exit section. A scraping member, which is in contact with the magnetic drum, drops sludge attracted to the magnetic drum toward the lower portion of the conveyor.Type: GrantFiled: July 20, 2007Date of Patent: January 11, 2011Assignee: BURNI IncorporationInventors: Minoru Tashiro, Makoto Tashiro
