Problems solved by technology

However, cleaning of filters to remove magnetic particles trapped by magnets in the filter is relatively expensive due to the substantial manual work required, the substantial need to stop production, the waste of large amounts of fluid, and the need for expensive equipment to achieve the cleaning

Embodiment Construction

[0010] Referring now to the drawings, numeral 10 generally designates a magnetic filter made in accordance with the present invention. The magnetic filter 10 includes a housing generally indicated at 12 which includes a longitudinally extending portion 14 and a pair of transverse end portions 16, 18 mounted at opposite ends of the longitudinally extending portion 14. . Each end portion 16, 18 includes: an end plate 20, 22, each of which is fixed to opposite ends of the longitudinally extending portion 14; Each of said cover plates is fixed to a corresponding end plate 20 , 22 .

[0011] The housing portion 14 is surrounded by a plurality (in this case six) of longitudinally extending, elongated, substantially parallel magnetic elements 30A-F. Magnetic elements 30A-F each include an outer housing 32 terminating in transverse ends 34,36. Each transverse end portion 34, 36 defines an aperture that receives a respective pin 38, 40 mounted on the respective end plate 24, 26, the...

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. <IMAGE>

Description

technical field [0001] The present invention relates to magnetic filters for separating magnetic particles from fluids. Background technique [0002] Magnetic particles are suspended in fluids produced by many industrial processes. For example, it is common to paint a car by dipping the entire body in a large paint bath. Since the body is assembled by welding, the welds are sandblasted and many iron particles remain loosely attached to the vehicle. When the vehicle is dipped in a paint bath, these particles will mix with the paint. Therefore, there is a constant need to remove particles from the paint. Similarly, cooling fluids (such as oil) used in many industrial machining processes may have magnetic particles suspended in them and must be removed from the oil. [0003] Centrifuges and magnetic filters have been used in the prior art to remove magnetic particles suspended in fluids. Centrifuges are effective at removing large particles but are less effective at removi...
