US 7,410,574 B2 · Magnetic particle filtration apparatus

Abstract

An apparatus for separating magnetic particles from a fluid, the apparatus comprising a tubular housing comprising an interior surface, an exterior surface, a first inlet port, a first outlet port, a second outlet port, and a channel; a tubular filter medium disposed within the tubular housing and comprising an inner surface and an outer surface, the filter medium partitioning the channel into a first passageway between the first inlet port of the tubular housing and the second outlet port of the tubular housing, and a second passageway in communication with the first outlet port of the tubular housing; and a wire coil wound around the exterior surface of the tubular housing, the wire coil comprising a first lead and a second lead. In operation, the wire coil is connected to a direct current power supply to effect enhanced separation of magnetic particles from a flowing fluid stream.
