Abstract
A device for feeding a granular material from an upstream source to a downstream location such as a mobile container. The device comprising a conduit for receiving a flow of said granular material and which has an outlet for delivering granular material to said location. Then device further comprises a delivery system for delivering a stream of gas to the conduit to entrain and accelerate at least a portion of the granular material flowing therethrough, and an apparatus for directing the gas stream so that granular material is propelled from the outlet in a plurality of directions.
Claims20
A device for feeding a granular material from an upstream source to a downstream location, the device comprising:
- a conduit for receiving a flow of the granular material, said conduit having an outlet or delivering the granular material to the downstream location;
- a pipe, having an open end, which extends into said conduit for delivering a stream of gas to said conduit to entrain and accelerate at least a portion of the granular material flowing through the conduit downstream of said open end of said pipe;
- and
- a generally conical first deflecting member positioned in the stream of gas between said open end of said pipe and said outlet to direct the gas stream so that the granular material is propelled from said outlet in a plurality of directions.
A device for feeding a granular material to a rail car, the device comprising:
- a conduit for receiving a flow of the granular material, said conduit having an outlet or delivering the granular material to the downstream location;
- a pipe, having an open end, which extends into said conduit for delivering a stream of gas to said conduit to entrain and accelerate at least a portion of the granular material flowing through said conduit downstream of said open end of said pipe;
- and
- means for directing the stream of gas so that the granular material is propelled from said outlet in a plurality of directions.
A device for feeding a granular material from an upstream source to a downstream location, the device comprising:
- a conduit for receiving a flow of the granular material, said conduit having an outlet for delivering the granular material to the downstream location;
- means for delivering a stream of gas to said conduit to entrain and accelerate at least a portion of the granular material flowing therethrough;
- a hollow deflecting member for deflecting said flow into said plurality of directions, said hollow deflecting member having an inlet opening facing upstream and an outlet opening defining a portion of said outlet of the conduit;
- and
- a second deflecting member for providing a channel between said inlet and said outlet of said hollow deflecting member through which granular material not entrained in, and deflected with, the stream of gas can be gravity fed to said outlet of said conduit.
