Abstract
An external filter assembly is shown having a slotted filter section, including an optional upper collar attached below the mounting member, and lower collar attached below the bottom cap of a lower filter element, where each collar includes a plurality of extensions containing magnets. Specifically, in the case of each extension, a bore is formed longitudinally within the extension, and a diametrically magnetic rare earth (neodymium) high-temperature rated magnet is permanently installed within the bore. Thus, with magnets installed in all of the extensions, metal debris passing through the assembly at any location, whether the upper collar or lower collar, is likely to be attracted to and retained by the extensions.
Claims7
An assembly for use in a conduit and for removing metal debris, comprising:
- (a) a mounting member for positioning the assembly in the conduit;
- and
- (b) a central member below the mounting member, wherein the central member includes an enclosed internal chamber, and wherein the internal chamber includes a plurality of magnets disposed within the central member;
- (c) a slotted filter attached below the central member;
- (d) a first plurality of radially disposed diffusing elements attached to the central member;
- and
- (e) a second plurality of radially disposed diffusing elements attached to the central member, wherein the diffusing elements of the second plurality of diffusing elements are angularly offset from the first plurality of diffusing members.
An assembly for use in a downhole conduit in communication with a drilling platform and for removing metal debris, comprising:
- (a) a mounting member for positioning the assembly in the downhole conduit;
- (b) a central member having a plurality of magnets disposed within an enclosed internal chamber of the central member;
- (c) an upper collar attached above the central member, and a lower collar attached below the central member;
- wherein the central member includes a first plurality of radially disposed diffusing elements attached to the central member;
- and
- wherein the central member includes a second plurality of radially disposed diffusing elements attached to the central member and angularly offset from the first plurality of diffusing members.
