Abstract
A magnetic filter is disclosed suitable for use in large heating and/or cooling systems, for example heating systems using pipework between 2 inch bore and 4 inch bore. The magnetic filter includes a separation chamber in the form of a pipe, and externally-mounted magnetic 5 assemblies which are movable from a position close to the pipe to a position spaced from the pipe. The magnetic assemblies are pivotally mounted to the pipe via a framework.
Claims23
A magnetic filter for a central heating and/or cooling system, the magnetic filter comprising:
- a chamber having an inlet and an outlet, and a movable magnetic assembly adapted to be movable from a position close to an outside wall of the chamber to a position spaced from the outside wall of the chamber, the movable magnetic assembly including an elongate carrier having a longitudinal centerline, and including a plurality of magnet pairs disposed along the carrier, each magnet pair having a first magnet on one side of the centerline and a second magnet on the other side of the centerline, the first and second magnets of each magnet pair being joined to each other by a bar passing across the centerline and the bar being movable relative to the carrier on a pivot, in which the pivot corresponding with at least one of the magnet pairs is offset from the centerline to one side, and the pivot corresponding with at least one other of the magnet pairs is offset from the centerline to the other side.
A magnetic filter for a central heating and/or cooling system, the magnetic filter comprising:
- a chamber having an inlet and an outlet, and an elongate magnetic assembly, the elongate magnetic assembly being mounted to the outside of the chamber on a pivot disposed near to one end of the elongate magnetic assembly, a major length of the elongate magnetic assembly being movable from a position close to the chamber to a position spaced from the chamber by pivoting the magnetic assembly on the pivot, and
- a minor length of the elongate magnetic assembly extending from the pivot point in a direction opposite to the direction of the major length, the minor length forming a stop for contacting the chamber when the major length of the elongate magnetic assembly is spaced from the chamber, to prevent further movement of the major length of the magnetic assembly away from the chamber,
- in which the magnetic assembly is spring-loaded into the position where the major length is spaced from the chamber.
