  • Patent number: 11391309
    Abstract: Material flow amplifiers comprise at least one helix vane within a vortex chamber of an amplifier body and at least a portion of an outer edge portion of the at least one helix vane is attached to an interior surface of the amplifier body. A centralizer tube is centrally located within the amplifier body and has at least a portion of an inner edge portion of the at least one helix vane is attached to an exterior surface thereof. Such material flow amplifiers provide for flow of flowable material within a flow passage of a material flow conduit to have a cyclonic flow (i.e., vortex or swirling) profile. Advantageously, the cyclonic flow profile centralizes flow toward the central portion of the flow passage, thereby reducing laminar flow to provide for increased flow rate in addition to reducing inner pipeline wear and energy consumption.

  • Patent number: 9416604
    Abstract: A mixing device has an elongate shell, an inlet, an outlet and at least one shear orifice between the inlet and the outlet. A hydration passage is located between the shear orifice and the outlet. The hydration passage has a flow area greater than a total shear flow area of the shear orifice, greater than an inlet flow area of the inlet and greater than an outlet flow area of the outlet. During operation, a polymer is mixed in a fluid flow flowing to the intake of a positive displacement pump, which pumps the fluid through the mixing device and into an injection conduit leading into a well. The shear orifice produces high shear separation of molecules of the polymer. The hydration passage causes hydration under pressure of the various polymer molecules in addition to blending the various chemicals and/or gases with other components of the fluid flow stream.

  • Patent number: 7922382
    Abstract: A method and apparatus for reconstituting consumable powder(s) with a liquid to provide a food liquid such as milk, cappuccino-type beverage, or soup with or without froth. The powder is introduced into a container and pre-wetted by an intersecting liquid spray. Further mixing occurs in the container. The container may have additional liquid streams feeding into the container for increased mixing. This food liquid can then be aspirated by the Venturi effect by steam generation to produce a frothed/aerated food liquid.

  • Patent number: 7794135
    Abstract: Disclosed are apparatus and methods for preparing wellbore viscous treatment gels from dry polymer and water. The apparatus includes an eductor which slurries dry polymer with water, at least two input tubes, wherein one input tube is connected with the eductor, and another to a water source. The apparatus also includes a mixing chimney connected to the input tubes. The mixing chimney includes a lower input section with inlets connected to the input tubes wherein a jet of metered dilution water is applied at high pressure to the incoming polymer-water slurry stream. This mixture is then accelerated in a circular, and preferably upward, motion where it is sheared against the wall of a central section of the chimney, without the use of an impeller. The chimney further includes an output section that comprising holes circumferentially located, through which the mixture passes from the central section and into a hydration tank.

  • Publication number: 20090296516
    Abstract: The dynamic mixer for mixing components in different volumetric amounts comprises a rotor housing (25) in which a mixing rotor is arranged and which is closed on the inlet side by a cover (45) on which inlets for the components are arranged. The inlet (47) for the first component having the larger volumetric amount leads to an antechamber (32) that communicates with a following mixing chamber (36) by at least one passage (19). The mixing rotor (10) includes a distributor body (13) located in the antechamber for distributing the first component around the axis of rotation of the mixing rotor. The inlet (48) for the second component having the smaller volumetric amount leads to at least one inlet opening (54) located in the area of the passage to the mixing chamber transversally to the axis of rotation.

  • Patent number: 7575364
    Abstract: A cyclone type cylindrical body 10 having a part whose diameter decreases in the direction toward a lower opening from an upper opening is used, and liquid is made fall in the inside of the cylindrical body 10 while swirling and thereby accelerated to form a vortex flow. Fine particles are charged into the center of the vortex flow so as to be wrapped by the vortex flow, and thereby the both are mixed. By this characteristic, the fine particles do not contact with an inner wall of the cylindrical body, and therefore clogging does not occur in the cylindrical body. Moreover, the pressure around the center of the vortex flow becomes negative, and the fine particles are aspirated. Therefore, dust is hardly generated. Thus, a mixing apparatus of a small size that can slurry fine particles without much maintenance cost can be provided.
