  • Patent number: 9433908
    Abstract: Rapid evacuation and deployment of dry materials is achieved by the dual structure of this device and the method of using it to fill and empty vacuum reloading tanks automatically. This permits materials such a bentonite, barite or cement to be handled easily and without dust on a rig floor and mixed appropriately as needed for well control and completion operations. Dry bulk material is offloaded from an offshore supply vessel into atmospheric tanks, which provide fluidized bed systems to aerate and agitate and move material through piping into the vacuum re-loader tanks. The dual re-loader tank system allows one tank to be emptied while another fills thereby providing sufficient flexibility to expertly manage receiving, storage, transfer, filtration and control of the bulk material on various space-critical platforms, including offshore rigs and service vessels, that require the handling of dry bulk materials in an accurate and dust-free manner.

A motor with speed control drives the feeder and determines the rate of seed discharge. A tank on the truck permits the pumped flow of tank contents, water and/or fertilizer, into the conduit carried pressurized air flow. Organic material carried by the truck is conveyed forward by a moving floor toward augers which feed the organic material to a powered mixer for breaking up of the material to ensure passage of loose material into a rotary feeder at a second station.

The collector includes a unique set of angled baffles which serve to thoroughly redistribute the recovered waste fibers back into the feed hopper for more even and uniform mixing with the new, virgin fibers being added. To accomplish this distribution the baffles are located so as to increase in surface area as a function of increased distance from the inlet.

    Abstract: A high slippage feeder for conveying seed cotton from a rotary vacuum of a cotton gin includes a cylinder rotating about an axis with a plurality of pins radially extending from the cylinder and a casing enclosing the cylinder and the pins. The casing has a first inlet for receiving the seed cotton from the rotary vacuum, a second inlet for receiving an air stream, and an outlet for providing an exit for the air stream and the seed cotton. A portion of the casing is curved to conform to an outer circumference defined by the rotation of the pins, and a portion of the second inlet is inwardly deflected to focus the direction of the air stream. The casing, as shaped, maximizes the operational efficiency of the high slippage feeder and not only improves the conveyance of cotton but also ensures that a majority of the cotton conveyed through the high slippage feeder will be partially dried.

  • Patent number: 5556237
    Abstract: A truck including a container used to transport and dispense loose particulate materials. A moving floor is located on the floor of the container to move loose particulate materials within the container into a feeder and dispensing system. The container includes two opposing augers mounted on the inner surface of a rear door of the container. The augers feed loose particulate material within the container to a mixer. The mixer helps to break up the loose particulate material to keep it from bridging as it drops into a feeder. The feeder regulates the flow of loose particulate material into a mixing chamber. A high volume air blower is connected to the mixing chamber. The blower forces a high volume of air through the mixing chamber and out of the mixing chamber into an attached hose. As loose particulate material drops into the mixing chamber, it mixes with the air flow and is blown out of the attached hose.

  • Patent number: 5480268
    Abstract: A rotary airlock feeder is connected to transfer particulate material between a storage bin and a pneumatic convey line. The pneumatic convey line includes a pressure reducing orifice plate which produces a pressure differential in the convey line between the upstream and downstream sides of the orifice plate. Air from the upstream side flows into respective specially designed end plates of the feeder and the pressure differential between opposite sides of the orifice assures a steady purge air flow circumferentially around a pair of rotary shrouds and into the feeder. This steady air flow prevents particulate material or debris from entering cavities between the shrouds and the end plates and between the rotary shrouds and the housing walls and thus prevents such material from reaching the seals, shaft area, and bearings of the feeder and protects the rotary shrouds from premature abrasive wear.

    Abstract: Ultrafine powder is stored in a pneumatic transportation tank (20), and is discharged to a transporting conduit (23) while being fluidized by the pressurized air fed through a fluidizing air port (24). The ultrafine powder is fed to a weigher (30) provided at the other end of the transporting conduit (23), at which the weight of the transported ultrafine powder is weighed by a load cell (31). After the weighed value reaches 90% of a predetermined value, the fed amount of the pneumatic transportation air is reduced, and a bypass regulating valve (38) is adjusted to thus decelerate the transportation. When the weighed value reaches 100% of the predetermined value, the discharge of the ultrafine powder to the transporting conduit (23) is stopped. This method and the apparatus enable the storage, quantitative batch transportation, and automatic weighing of the ultrafine powder such as silica fume.
