Abstract
The magnet filter (10,100) has a frame for supporting a plurality of elongated, non-magnetic tubes (20, 108) in a regular, spaced-apart array. A plurality of magnetic bodies (38,112), which can take a variety of forms, are situated in the spaces between the tubes of the array, for imposing a magnetic field within each tube over substantially the full length of each tube. The upstream end of each tube is adapted for receiving a fluid to be magnetically filtered and the downstream end is adapted for discharging such fluid. As the fluid passes through each tube, the magnetic field imparts a force to the magnetizable particulates, which are drawn toward the magnetized internal structure within the tube where they are deposited, thus filtering the fluid. The magnetic bodies may produce a field that is oriented either substantially parallel to the tube, or transverse to the tube. The latter arrangement is particularly effective when used in conjunction with a plurality of magnetizable bars (112) supported in spaced-apart relation within each tube to provide an increased surface for particulate deposition within the tube.
