Abstract
A cleanout system and method for removal of metal debris from a fluid flow, such a flow of re-circulated drilling mud employs one or more magnetic unit positioned in the path of the fluid for collecting metal particles from the flow. The magnetic unit has a removable magnet core positioned in a non-magnetic sleeve. When the core is removed from the sleeve the attracted metal particles are allowed to drop from the sleeve under gravity to facilitate their collection and disposal. A fluid deflector is positioned upstream from each magnetic unit, protecting the magnetic unit from direct impact by the strong flow. The magnetic units are allowed to pivot from side-to-side and adjust their position in the flow.
