Abstract
A magnetic filter removes magnetic particles from fluid communicated through the filter. The filter includes elongated, circumferentially spaced magnetic elements which capture magnetic particles entrained in the fluid. The magnetic elements must be cleaned periodically to remove the particles from the elements by moving a scraper plate from one end of the housing to the other. At the end of travel of the scraper plate, the particles are scraped upon non-magnetic end portions (which may contain residual magnetism) of the magnetic elements, from which they are flushed by fluid communicated through the inlet port out through other ports provided on the housing.
Claims20
Magnetic filter for removing magnetic particles suspended in fluid comprising a housing having an inlet port for communicating said fluid into said housing and an outlet port for discharging said fluid from said housing, an elongated magnetic element mounted in said housing for magnetically attracting and capturing on said magnetic element magnetic particles entrained in said fluid, a scraper slidably mounted on said magnetic element, an actuator for periodically moving said scraper along said magnetic element to remove magnetic particles captured by said magnetic element from said magnetic element by scraping said particles toward one end of said magnetic element.
