ABSTRACT:
An improvement on a silo for delivery of fluid bulk material, such as livestock feed, grain, flour, spices, sugar, and similar provides for an inner compartment adjacent to the bottom of the silo of the shape approximately of a truncated cone or funnel, with the wider periphery thereof merging with the inside of the cylindrical wall of the silo and with the narrower periphery extending into a shorter vertical wall merging with the bottom of the silo. The lower portion of the cylinder wall of the silo forms with the truncated cone shell within it an annular channel. A central cone rises from the center of the bottom of the compartment. Material release openings are provided within the vertical cone wall and lead from the compartment into the channel.
The channel is provided with a material discharge opening toward the outside of the silo. The bottoms of the compartment and of the channel are suitably inclined to aid the transport of the material.
Outside controls of the sizes of the material release openings are provided.
The bottoms are provided with open airducts which aid the transport of the material and with means to supply pressurized air from the outside controllably to various sections of the device as required. An automatic cyclical distribution control of air is also provided for.
Optimum angles of inclinations of the walls and bottoms over which the materials glide by gravity to its several destinations are demonstrated.
