Abstract
A belt cleaning system to clean a conveyor belt having a carrier surface includes a dry ice blasting device and a debris recovery subsystem. The dry ice blasting device includes a delivery system having at least one nozzle disposed adjacent the conveyor belt. Dry ice pellets are discharged from the nozzle onto the conveyor belt carrier surface, whereby the dry ice pellets remove the debris from the carrier surface. The debris recovery subsystem includes a collector housing disposed adjacent to the conveyor belt carrier surface. The collector housing contains the debris removed from the conveyor belt carrier surface and directs the debris away from the conveyor belt.

A belt cleaning system to clean debris from a conveyor belt having an outer carrier surface to transport paper articles to and from a laser cutting device and an inner surface, the system comprising:
- a dry ice blasting device including a delivery system having at least one nozzle disposed adjacent the conveyor belt adapted to discharge a plurality of dry ice pellets onto the conveyor belt carrier surface, whereby the dry ice pellets remove the debris from the carrier surface;
- and
- a debris recovery subsystem including
- a collector housing disposed adjacent to the conveyor belt carrier surface, the collector housing being adapted to contain the debris removed from the conveyor belt carrier surface and to direct the debris away from the conveyor belt, and
- a first seal sealing the collector housing to the dry ice blasting device delivery system and a second seal sealing the collector housing to the conveyor belt.
