Abstract: A directional hopper tee has a fluted interior vertical pipe that merges into a horizontal pipe. The vertical pipe has an opening that connects to a hopper to receive bulk material, or product, and a horizontal pipe centered upon the end of the vertical pipe. The horizontal pipe has an inlet that also receives bulk material and pressurized air from ahead of the hopper and an opposite outlet that discharges the bulk material from the hopper tee. The vertical pipe has a flange that abuts the hopper and an opening in the flange that matches the opening of a valve on the hopper itself. At the opening, the vertical pipe begins to turn towards the outlet of the lower pipe with an internal flute. The flute begins immediately at the flange resulting in a vertical pipe with a curved shape towards the outlet and a square shape towards the inlet. The present invention raises the ground clearance of the horizontal pipe by at least an inch resulting in a hopper tee that clears at least 7 inches above the ground.
Abstract: A pneumatic aerator aids in bulk material unloading, handling and transport using tank trailers, hopper cars, and other containers, as its aerator introduces a cyclonic air flow and vibration into the bulk material. This aerator has a housing, one or three guide tubes, an aerator extending through the housing, a gasket upon one end of the aerator generally within the container of the bulk material, and an optional wearplate beneath the gasket. The aerator has a stem with one vane, preferably three vanes, where the vanes and contiguous fins curve counterclockwise in a helical manner. The airflow past the fins and vanes acquires a counterclockwise rotation, rotating the air as it exits radially from the gasket increasing the bulk material unloaded per hour. This aerator also has various gasket thicknesses and edge conditions, guide tubes, and various shapes in the vanes and fins for alternate speeds and directions of airflow.
Abstract: A mounting assembly uses one hinge and one cam bolt mutually offset upon a two piece collar. A hopper tee has a member usually a vertical pipe and occasionally a horizontal pipe that connects to a hopper flange to receive bulk material. This assembly has two collars that mutually engage and surround a hopper flange. Pins pass through the collar pieces and the hopper flange then secure to tapped holes in the collar pieces to prevent rotation. A collar piece mounts a hook bolt and the other collar piece mounts a hinge in a spaced apart and offset manner. The other collar piece has a pivotal connection to a hinge arm and opposite the hinge arm, the hook bolt engages a cam. Opening the cam unfolds the tee downwardly while the hook bolt remains engaged. This partially open position allows for removal and installation of a valve. In opening and closing the assembly, the hinge arm spaces the flange below a hopper to admit a valve.
Abstract: Apparatus and method are provided for storing selected quantities of granular materials, for programmable extraction in selected proportions and at selected rates, for delivery to a changeable location through a flexible auger-driven common delivery conduit. Individual containers containing specific granular products are mounted so that they are continually weighed by load cells communicating with a central control system including a microprocessor. Each of the containers is provided with an individual valve which is controllable by the microprocessor pursuant to a user-provided program, so that precisely determined and timed gravity-assisted extraction of the granular materials is effected. Auger mounted immediately below each container to positively transfer the extracted granular material along the delivery conduit. By the addition of a liquid carrier, either from one of the cooperating containers or after delivery of the granular material to the selected location, slurries, e.g.
