    Abstract: An indicator system is provided for use with a blown-in dust transfer system. A dust collector collects dust, where it accumulates at an airlock feeder. When the feeder moves, accumulated dust is dispensed into an introduction chamber. A blower moves air through an introduction chamber where the dust particles become entrained in the moving air. The dust and air mixture are moved into a removable storage container where the dust particles fall out of the moving air. Return air that is mostly devoid of dust returns to the introduction chamber. Between the storage container and the introduction chamber is a sensor that detects dust in the return air. If the level of dust reaches a certain amount the sensor detects it and an operator is notified that the storage container is full.

    Abstract: Make-up water derived from an on-shore treatment facility is returned to a slurry processing unit on board a dredge by means of a water supply pipeline floating alongside a slurry delivery pipeline that conveys dredged material to the on-shore treatment facility. After separation from the slurry solids, the return water is pressurized to a transport pressure at the treatment facility with a centrifugal pump and then boosted to the desired working pressure once aboard the dredge. This two-stage pumping and re-cycling process reduces the amount of clear make-up water needed for proper operation of the slurry processing unit by more than 50%. This has resulted in a substantial reduction in the overall cost of remediation by reducing the amount of water that must be cleaned prior to disposal.

  • Patent number: 5478172
    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.
