Abstract
A fully integrated insulation spraying system with an insulation spraying subsystem for spraying wet or dry insulation and a fiber recovery subsystem for recycling waste insulation fibers and reintegrating them into the spraying process for more efficient and ecologically sound use of the insulation material. The insulation spraying subsystem includes a hopper with a rotary conveyor that conditions the fiber insulation and carries it into a standby chamber which is connected an airlock that introduces the fibers into a moving airstream. The airstream carries the fibers to the spraying head where moisture is added to promote adhesion of the insulation. A pneumatically powered insulation shaver is provided for smoothing the insulation after it is applied. The fiber recovery subsystem includes a vacuum powered pickup for gathering the waste insulation that is shaved off, a cyclone separator and primary and secondary filters for collecting the fibers, and an airlock for metering the fibers into the airstream of the insulation sprayer. Preferably, the system is mounted on a truck for transportation to a construction site. A self-contained power unit, which operates the air pumps, water pump and mechanical components of the system, further increases the portability and efficiency of the system.
