Abstract
A magnetic particle separating device in which magnetic particles entrained or contained in coolants, lubricants or working fluids are separated and removed by the application of magnetic fields.
Claims6
A magnetic particle separating device for use in association with a hydraulic pipe through which flows a liquid with entrained magnetic particles, said separating device comprising:
- branch means associated with the hydraulic pipe for dividing the flow in the hydraulic pipe between a first branch and a second branch defining a magnetic particle separation pipe which receives magnetic particles separated from the liquid, said branch means comprising a flattened shell defining a flow passage having a considerably increased cross sectional area over that of the hydraulic pipe;
- traveling wave magnetic field generating means for generating a traveling wave magnetic field that directs the entrained magnetic particles to flow into said magnetic particle separation pipe, said generating means comprising a pair of flat members one of which is mounted on each of the major exterior walls of said flattened shell;
- and
- a first magnet mounted on said hydraulic pipe so that magnetic particles entrained in the liquid are magnetized before they reach the traveling wave magnetic field generating means.
