Abstract
A flow cone aerator for assisting discharge of material from containers. The aerator includes an inverted cone shaped hollow support adapted to be affixed to a wall of the container with the small diameter end of the support adjacent the interior surface of the container and the large diameter end extending into the interior of the container. An air inlet is positioned adjacent the small diameter end and is adapted to be selectively connected to a pressurized source of air exteriorly of the container. At least one air outlet port radially extends through the wall of the support. A flexible cone shaped flap, corresponding in shape to the support, is mounted to the small diameter end of the support with the large diameter end of the flap free of attachment to the support. The flap flexes toward and away from the support to close and open, respectively, the outlet port and to permit the flow of air into the material stored in the container so as to aerate the material to facilitate the efficient pneumatic discharge of the material from the container.
