Abstract
A preassembled fluidizing device that incorporates an expansive air passage that stimulates the enhanced flow of granular materials to the discharge port of a tank trailer, vessel, bin, or other container, during usage. The fluidizing device includes an aerator housing having affixed thereto a wear plate, the upper end of the housing having a mount to which a resilient gasket may be applied, and prestressed against the wear plate, once assembled. A fastening rod extends from the aerator housing and mounting boss, and a positioning or clip secured thereto provides an initial fastening of the preassembled device in place, once installed. A nut or other fastener connects with the opposite end of the fastening rod in order to tightly secure and seal an air distributor in place, for final assembly of the fluidizing device of this invention.
