Apparatus for cleaning a coiler furnace drum

A coiler drum cleaner, for use in removing unwanted matter from a rotating drum in a coiler furnace, the drum having a work surface extending over a drum length, the coiler drum cleaner comprising:

• a) a cleaning element engageable with unwanted matter on the work surface for removing the unwanted matter;
• b) insertion means, supporting the cleaning element, for retractably inserting the cleaning element into the coiler furnace;
• c) biasing means operable to bias the cleaning element to move from a rest position out of contact with the work surface toward and into close proximity with the work surface;
• and
• d) cleaning movement means for moving the cleaning element axially relative to the drum over a path of travel sufficient to cover the drum length;
• wherein, when in use, the cleaning element is movable into close proximity to the work surface along the drum length so as to bring the cleaning element into contact with different portions of the work surface along the drum length.

A coiler drum cleaner, for use in removing unwanted matter from a rotating drum in a coiler furnace, the drum having a work surface extending over a drum length, the coiler drum cleaner comprising:

• a) a cleaner frame, installed adjacent to the coiler furnace;
• b) a longitudinally-extending cleaning element support member having an insertion end for insertion into the coiler furnace, the cleaning element support member being supported by the cleaner frame and axially displaceable relative to the cleaner frame, wherein the insertion end of the cleaning element support member is axially retractably insertable into the coiler furnace and movable axially along the work surface over the drum length;
• c) axial moving means for axially displacing the cleaning element support member relative to the cleaner frame;
• d) a carriage, radially-movably mounted to the cleaning element support member proximate to the insertion end of the cleaning element support member, such that the carriage is reversibly radially displaceable relative to the cleaning element support member towards the work surface;
• e) a rotatable cleaning element engageable with unwanted matter on the work surface, rotatably mounted to the carriage;
• f) means for radially displacing the carriage and cleaning element relative to the cleaning element support member toward the work surface, operable to bias the cleaning element to move from a rest position out of contact with the work surface toward and into close proximity with the work surface;
• and
• g) a motor, mounted on the cleaning element support member and drivingly coupled to the cleaning element, for rotating the cleaning element;
• wherein, when the coiler drum cleaner is used to remove unwanted matter from the work surface, the insertion end of the cleaning element support member is inserted into the coiler furnace;
• the cleaning element is caused to rotate and is moved into close proximity with the work surface;
• and the cleaning end is moved along the drum length.
