  • Patent number: 10218247
    Abstract: An electric pump powered by an electric motor having a stator disposed within a hollow rotor is provided. Impellers on the rotor outer surface extend into a fluid flow path defined by the pump. One or more torque-producing rotor sections are driven by a plurality of independently controllable stator sections disposed within the rotor cavity. The relative positions of the rotor and stator are maintained by a plurality of bearings configured to allow rotation of the rotor and defining a bearing span. The pump is configured such that the stator and rotor share the same bearing span. Such an arrangement reduces motor windage losses relative to conventional motors in which the rotor is disposed within the stator, owing to a reduction in the diameter of the air gap between the stator and the rotor. In addition, the peripheral speed of the pump is increased owing to an increase in the rotor diameter.

  • Patent number: 8844773
    Abstract: A booster pump for a coffee beverage dispenser's water inlet source, in one example, a “city water” inlet. A chamber is formed which has the diluent/water inlet and a bottom surface and a top end covered by a removable lid. The removable lid has a hole large enough for a motor to be partially seated within the chamber and the motor has a shaft with supports that is connected to a cover plate that has through holes, and a rotor below the cover plate with a set of radially oriented vanes. The hole in the lid is bigger than the cross section of the cover plate and so the motor, shaft, supports, rotors and cover plate can be pulled out as desired for easier maintenance. When the motor is seated properly in the hole of the lid, the cover plate seats properly along the edge of a cylindrically shaped pump cavity. The cover plate and the edge form a seal. The inlet for the pump cavity has a smaller cross section than its outlet and the pump cavity can have a deflection body.

  • Patent number: 6877959
    Abstract: The invention is an improved surface aeration impeller for use in a liquid filled tank which particularly increases the surface turbulence and the entrainment of gas into the liquid surface. The impeller is an axial flow impeller and may be either a pitched blade turbine (PBT) or have airfoil shaped blades. In either case, the impeller has a portion which extends radially along an edge thereof which projects above the surface of the liquid being mixed in a vertical direction. The blades of the impeller are modified to include a top horizontal plate to lower the spray height of the liquid and an optional endcap, both of which can enhance and increase the standard aeration efficiency. Preferably, the impeller is rotated in an up-pumping direction and propels the liquid being aerated in a radially upward and outward direction. A sufficient upward surge of liquid is produced so that the liquid is observed to splash back onto the surface a plurality of times in the course of operation of the impeller.

  • Patent number: 6315441
    Abstract: The present invention is a mixing device and a method of mixing viscous fluids with a mixing device. The mixing device includes a shaft and a support mounted for rotation with the shaft. A plurality of vanes extend from the support and are mounted for rotation with the shaft, the vanes extending generally parallel to the shaft and positioned radially outward from the shaft. The vanes have a sloping inner edge which is positioned closer to the shaft at a first portion of the vane than a second portion of the vane. In use, the mixing device is located in a viscous fluid and the shaft is rotated, thereby effecting rotation of the vanes, causing fluid to move through the vanes and mix the fluid.

  • Publication number: 20010022755
    Abstract: A mixer for producing a substance mixture includes a rotatable shaft and a body submersible within a first substance. The body includes a first end and a second end. The first end is coupled to the shaft, and the second end includes an outwardly flared opening. The mixer also includes a plurality of apertures disposed on a wall of the body. Rotation of the body draws the first substance and a second substance into an internal area of the body and dispels the substance mixture outwardly through the apertures. The mixer may also include a diverter for diverting the substance mixture toward the apertures. The mixer may further include internally formed vanes to increase a substance flow rate into the mixer. Screens may also be disposed outwardly from the apertures to enhance mixing of the first and second substances.

  • Patent number: 6280078
    Abstract: A mixing apparatus comprising a central disc driven by a rotating shaft. A number of mixing plates are stacked above and/or below the central disc. The mixing plates are spaced from and parallel to the central disc. Each plate has a central aperture and the diameter of the central aperture increases progressively away from the central disc to define a space coaxial with the rotating shaft. In operation, fluid is drawn into the space and directed out through the space between the plates. When placed near the surface of a fluid, air is drawn in and the fluid is aerated as well as mixed.

  • Patent number: 6190033
    Abstract: A glass coated gas dispersing impeller. The impeller comprises a hub, having a centrally located hole. The hole has a central axis and is sized for passage over a drive shaft having an essentially vertically extending longitudinal axis so that the central axis of the centrally located hole corresponds with the longitudinal axis of the shaft. The impeller has a plurality of angles and edges, all of which have a rounded configuration. The impeller further comprising a plurality of blades secured to the hub that extend radially outward from the central axis. Each of the blades has a leading concave surface and a trailing convex surface both of which are defined by a lower edge, an upper edge, an inner edge and an outer edge. The concave surface is configured so that the upper edge overhangs the lower edge. The blades may be connected to the hub directly or by intermediate connecting means such as a disk or arm integral with the hub and extending radially outwardly from the central axis.

  • Patent number: 5407271
    Abstract: A rotary mixer and disperser head consisting of a shaft to which is connected a mixing chamber that is to be disposed into a vat or the like for dispersing, dissolving or blending of solids liquids or gasses with other liquids. The mixing chamber has secured to its upper and lower ends a plurality of impeller blades that have an end thereof located outside the mixing chamber to direct material into the mixing chamber and out through openings in the side wall of the mixing chamber during the mixing and dispersing thereof. The shaft for rotating the mixing chamber is merely located at one end thereof and doesn't extend into the mixing chamber and thus does not impede the mixing action taking place therewithin. The specific location of the blades, their relationship relative to the mixing chamber and their configuration provide for a very efficient mixing operation.

  • Patent number: 5314310
    Abstract: The present invention provides a mixing impeller including a plurality of blades circumferentially mounted to a frame around the mixing impeller with adjacent blades being opened from one another. The blades are secured to the frame in a manner such that at least part of each blade extends outwardly of the frame to guide discharge of fluid passing through the impeller away from the frame and substantially eliminate any turbulence that the frame might otherwise create. In addition, the frame has a rearwardly inwardly tapering configuration with each of the blades having the same inward rearward taper as that of the frame. This combination of features substantially reduces turbulance of the outward flow of liquid from the impeller relative to conventional impeller designs.
