    Abstract: A tank agitator connects to a low head feed and causes agitation by discharging through a port that might rotate, oscillate, or otherwise issue a pulsing stream. This agitator has a housing with a turbine plenum and an exhaust plenum. A turbine in the turbine plenum spins by the flowthrough of the feedwater and exhausts to the exhaust plenum. A hollow drive shaft is spun by the turbine and extends through the exhaust plenum and to terminate outside the housing. It has an aperture that allows water in the exhaust plenum to flow into its lumen. A nozzle caps the shaft and is bent such that the discharge issuing therefrom sweeps in circles with the spinning of the drive shaft. A variant form of the agitator includes a drive train that incorporates a drag link to convert the spinning input of the turbine into an oscillating output in the drive shaft. In another variant form, the discharge is pulsed.

  • Patent number: 6655830
    Abstract: A tank agitator connects to a low head feed and causes agitation by discharging through a port that might rotate, oscillate, or otherwise issue a pulsing stream. This agitator has a housing with a turbine plenum and an exhaust plenum. A turbine in the turbine plenum spins by the flowthrough of the feedwater and exhausts to the exhaust plenum. A hollow drive shaft is spun by the turbine and extends through the exhaust plenum and to terminate outside the housing. It has an aperture that allows water in the exhaust plenum to flow into its lumen. A nozzle caps the shaft and is bent such that the discharge issuing therefrom sweeps in circles with the spinning of the drive shaft. A variant form of the agitator includes a drive train that incorporates a drag link to convert the spinning input of the turbine into an oscillating output in the drive shaft. In another variant form, the discharge is pulsed.

  • Patent number: 6616325
    Abstract: Apparatus for mixing a material contained in a vessel comprises one or more flow channels and at least one pair of first and second members which are coaxially mounted one within the other about an axis of rotation such that their facing surfaces curve around the axis defining a chamber therebetween. At least one of the first and second members having a non-circular curvature, the first and second members being rotatable relative to one another about the axis to thereby produce a pumping force to force material through said flow channels. The radially outermost of said first and second members moves to a wall of the vessel relative to stress and displace material present between the mixing apparatus and the wall of the vessel.

  • Publication number: 20030123324
    Abstract: This invention relates to a fluid driven agitator used in densified gas cleaning system, which comprises a hydraulic motor mounted to a cleaning vessel of the densified gas cleaning system, wherein the hydraulic motor comprises a fluid in-port for charging the fluid into the hydraulic motor from outside of the cleaning vessel, and a fluid out-port for discharging the fluid from the hydraulic motor out of the cleaning vessel. An output shaft of the hydraulic motor can be joined to a rotatable component, such as a rotary basket or an impeller, subjecting circulation of the fluid and resulting in stirring.

  • Publication number: 20030090956
    Abstract: A method and device are described for mixing an oil-containing liquid stored in an oil storage tank to determine the monetary value of said oil-containing liquid contained therein. The method comprises rotating an agitating device in the oil-containing liquid; providing a mixed oil-containing liquid; and determining the monetary value of the oil in said oil-containing liquid. The device includes a shaft disposed in the tank and extending along a central axis of the tank. The shaft includes at least one arm structure extending outward from the shaft so that when the shaft is rotated, the arm structure causes the liquid components to be mixed. The shaft is rotated by a power actuating device which may be a fuel powered motor, an electric powered motor a wind turbine or a manual hand crank.

  • Publication number: 20030067839
    Abstract: A surface aeration impeller for use in a liquid filled tank. The impeller is rotatable about an axis perpendicular to the static liquid surface. The impeller has a plurality of blades mounted on the underside of a disc or disc-like surface. Each blade has a multi-faceted or curved geometry ranging from vertical at the point of attachment to the disc to partially inclined at the bottom. The blades are spaced circumferentially about the axis and are disposed at acute angles to radial lines from the axis of rotation of the impeller. The lower portions of the blades, which are inclined but non-vertical, are positioned at or below the static liquid surface. When the impeller is rotated, the lower portion pumps the liquid up onto the vertical portion of the blades where the liquid is discharged into a spray umbrella in a direction upwardly and outwardly away from the impeller.
