ABSTRACT:
A new apparatus for suspending and transporting particulate material is described. The apparatus is particularly useful for transporting and depositing thermal insulation into building spaces. The apparatus includes a conduit junction having a particle inlet conduit for the particulate material, an outlet conduit and an air inlet conduit to supply air under pressure for suspending the particulate material passing into the junction, e.g. from a closed receptacle such as a plastic bag in which the particulate material is stored. The air inlet conduit provides air at superatmospheric pressure to the closed receptacle, thereby placing the stored particulate material and the interior of the receptacle at or above the air pressure in the junction. The particulate material is then able to move into the junction without traversing an air current travelling in the opposite direction. The outlet conduit carries air and particulate material away from the junction to a delivery point. The outlet conduit preferably has connected to it a delivery conduit such as the flexible hose to carry the air and particulate material to a desired location. An air pervious member or screen is preferably mounted within the junction in a suitable location to prevent particulate material from travelling out through the air inlet; and a pressure relief valve is preferably provided to exhaust air exceeding a predetermined pressure.
