Abstract
A machine for fluffing fiberglass insulation at a faster rate than heretofore possible, introducing an antistatic material and blowing the material to a point of installation a greater distance from the machine than heretofore possible. In addition to fluffing the insulation to assure the necessary insulative qualities, the fiberglass material must also be treated with an anti-static solution to make it capable of appropriate placement and to reduce the dust and flyaway prevalent with this type of operation.
Claims4
An apparatus for fluffing, treating and blowing insulation, comprising:
- hopper means to receive and temporarily store insulation;
- hammer mill means to beat the insulation until it is fluffed;
- blower means for moving the insulation from said hammer mill means through a conduit means to said blower means and from there to a remote location, said blower means including impeller means which comprises a shaft and a plurality of impeller blades extending outwardly therefrom;
- and
- means introducing anti-static liquid into said conduit means, at such a position relative to said blower means and at such a rate and with such a trajectory relative to the airflow through said conduit means resulting from the operation of said blower means that the anti-static liquid impinges upon an exposed end of the rapidly turning shaft of said impeller means in said blower means, wherein the anti-static liquid, upon contact with the rapidly turning shaft, is splattered throughout the insulation within said blower means.
