A ferromagnetic material removing device for removing ferromagnetic material from a fluid containing ferromagnetic material, wherein the device comprises:
- at least one carrier encasing a plurality of permanent magnets arranged in an inner space of the carrier, wherein an outside of the carrier is configured to collect ferromagnetic material that is attracted by the permanent magnets, wherein the carrier is rotatably mounted;
- a removing portion arranged and configured to remove the ferromagnetic material from the outside of the carrier;
- and
- a driving assembly arranged to rotate the carrier, the driving assembly comprising one or more rotatably mounted engagement members brought into engagement with the outside of the carrier;
- wherein the carrier is ring-shaped and the carrier comprises a magnet free zone.
A method for removing ferromagnetic material from a fluid containing ferromagnetic material using a ferromagnetic material removing device, wherein the method comprises the following steps:
- submerging a carrier into the fluid, wherein said carrier encases a plurality of permanent magnets arranged in an inner space of the carrier, wherein an outside of the carrier is configured to collect ferromagnetic material that is attracted by the magnets;
- and
- releasing the ferromagnetic material from the outside of the carrier, wherein the carrier is rotatably mounted and a removing portion is arranged and configured to remove the ferromagnetic material from the outside of the carrier while rotating the carrier;
- wherein the rotation of the carrier is carried out by a driving assembly that comprises one or more rotatably mounted engagement members that are brought into engagement with the outside of the carrier;
- wherein the carrier is ring-shaped and the carrier comprises a magnet free zone.
