    Abstract: An air distribution apparatus has a manifold body, and ports defined through walls thereof, with a delivery conduit connected to each port. A port valve is configured to connect and disconnect the delivery conduit to the interior of the manifold body. A supply conduit delivers a product air stream with agricultural products entrained therein to the interior of the manifold body. The supply conduit extends vertically up from the manifold to a curved elbow and then extends horizontally from the elbow. An exhaust orifice is defined in the inner radius of the elbow. When an exhaust valve is open, a selected flow of pressurized air flows from the supply conduit through the exhaust orifice. The port valve and exhaust valve are controlled such that when the port valve closes, the exhaust valve opens. The exhaust air can be directed into the delivery conduits to clear product therefrom.

  • Patent number: 8726532
    Abstract: Methods and systems are disclosed for drying a material or, more generally, flash evaporating a target substance having a vapor pressure threshold. The methods and systems include a conveyor conduit that receives material. The material moves through the conveyor and is expelled into a pressure drop zone created by one or more venturi nozzles. As the material encounters the pressure drop zone, the targeted substance in the material experiences a rapid and extreme pressure drop and simultaneously a rapid temperature increase. This causes the target substance in the material to flash evaporate virtually immediately. The resulting vapor is separated from the remaining material and the now dry material is collected for further processing or use. The vapor can be collected, condensed, exhausted, or otherwise treated depending upon the goals of a particular installation or process.

The system includes one or more extractors that draw the bulk aggregate material from the hold(s) of the ship by entraining the aggregate in a stream of water and air. The aggregate is automatically cleaned during this step, and passes to a separating hopper where the sand and water settle out and the clean gravel is transferred to surface transport. The sand and water pass to a settling tank, where the sand is recovered for use and the water is recycled for continued use.

  • Publication number: 20040071514
    Abstract: The present invention is directed to a device for pneumatic or hydraulic conveying of dusty, powdery or granular bulk material. The device includes a conveyor line, an inner pipe in the conveyor line that is parallel to the axis and preferably eccentric. The inner pipe has openings at intervals and flow resistors within itself, which have an upstream side plane and a downstream side plane in the region of the openings. As a result, outlet openings into the conveyor line and entrance openings into the inner pipe are formed for the conveying medium, characterized in that the upstream side plane forms an angle (&agr;)<90° with the axis (14) of the inner pipe (2) and deflects the striking conveying stream towards the outlet opening (20, 20a, 20b).

  • Publication number: 20030017012
    Abstract: An air pulser is provided which can intermittently form pulse air by continuously supplying compressed air. The interior of the body is partitioned into an air supply chamber and an air exhaust chamber by a diaphragm. An air blast cylinder opened and closed by the diaphragm is provided in the air supply chamber. In the air exhaust chamber, a valve plate having a valve hole and comprising a magnetic member is provided to partition it into a first chamber and a second chamber. A valve body with a permanent magnet is movably mounted in the second chamber. By continuously feeding compressed air into the air supply chamber to open the valve body due to an increase in pressure in the first chamber, thereby exhausting compressed air in the air exhaust chamber through an air exhaust port, and to deform the diaphragm toward the air exhaust chamber due to a drop in pressure in the air exhaust chamber, thereby discharging compressed air in the air supply chamber through the air blast cylinder.

  • Patent number: 5779398
    Abstract: Method and system unloads dry bulk materials from a tank hopper supported on a trailer, the trailer being connected to a tractor. A material conveying conduit is adapted for receiving material from the hopper. A blower is provided for supplying pressurized air to the hopper and to the conduit so that a pressure differential is created between the hopper and the conduit to thereby induce the flow of the materials from the hopper to the conduit. The pressurized air is cooled via a radiator which transfers heat from the pressurized air to ambient air. Ambient air is caused to flow across the radiator by a fan that is electrically driven by a battery located on the tractor, and that is automatically controlled by a pressure sensor switch positioned for sensing the pressure of the pressurized air stream.

  • Patent number: 5390501
    Abstract: A hydraulic conveyance system serves to level out a spiked, uneven flow of particulate material to a more even flow condition prior to the particles being delivered to a destination. In one particular application, the hydraulic conveyance system permits ice particles to be delivered from a batch discharge ice machine of a thermal energy production, storage and reclaim system to the thermal energy storage tank of the system at a relatively even rate, without the use of any mechanical delivery mechanisms. The hydraulic conveyance system incorporates a flooded hold-up tank which, in the case of particulate ice conveyance, receives the spiked, batch discharge from the ice machine and discharges the ice therefrom to a selected number of destination points at a more even flow condition. A rotational movement is imparted to the water surface in the flooded hold-up tank, thereby causing the floating ice particles to rotate in the tank in proximity to a boundary wall of the tank.
