    摘要： The invention pertains to 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 which 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 mixer and disperser head also comprises shear arms having a sharpened leading edge, thereby providing an additional initial shear zone. The specific mixing chamber and its configuration provide for a very efficient mixing operation.

    摘要： A mixer assembly comprises a motor, a motor shaft, a propeller connected to the motor shaft and in operation driven by the motor in a first direction of rotation about a propeller axis, the propeller fully submersed in liquid during operation and in rotation generating liquid flow from a suction side to a pressure side of the propeller. Flow control vanes are arranged on the suction side of the propeller, and oriented in an axial plane to deflect the liquid from substantially axial flow into a flow containing a circumferential component of direction which is opposed to the direction of rotation of the propeller. A method for providing axial liquid flow from a mixer propeller that is fully submerged in liquid during operation comprises the steps of applying flow control on the suction side of the mixer propeller through the arrangement of flow control vanes.

    摘要： A system and method for oxygenating an aerobic sludge digester is provided. The disclosed embodiments include an aerobic sludge digester tank or vessel having a mechanically agitated contactor disposed therein, an oxygen injection subsystem adapted to inject oxygen into the digester tank proximate the mechanically agitated contactor. The embodiments of the mechanically agitated contactor include an agitator or impeller disposed within the draft tube which makes the draft tube the primary site for the gas-liquid mixing. In particular, the agitator or impeller is adapted to create gas bubbles having an average diameter between about 0.3 mm and 3.0 mm which are then dispersed into the aerobic digester. The mass transfer efficiency associated with the present system and method is enhanced from the combined effect of oxygen dissolution into the sludge and greater bubble residence time.

    摘要： An apparatus for mixing gas and liquid is disclosed. The apparatus includes a draft tube having a gas inlet, a liquid inlet, a gas-liquid outlet, and an impeller rotatably mounted within the draft tube. The gas can be entrained into the liquid by rotation of an impeller having a low pitch ratio, such as less than 1:1. The impeller can have a diameter than is greater than the axial length of the impeller and includes at least one blade extending at least 30° around an axis of rotation of the impeller. Liquid turning vanes can also be positioned external to the draft tube to rotate liquid entering the draft tube in a direction opposite the direction of rotation of the impeller. The impeller can be constructed to create a reduced pressure zone, which directs gas axially downward within the draft tube upon rotation of the impeller.

    摘要： In order to extend the life of mixing impellers which circulate materials, and particularly which suspend solids, in the form of particles which erode the blades of the impellers and place a practical limit on impeller speed and/or angle of attack due to increased erosion at high flow velocity (erosion being a function of the cube of the velocity), the blades are constructed from blades into an airfoil configuration which does not limit the thickness of the plates and thereby allows the use of thick plates having extended life. An erosion resistant layer is located at least over the leading edge region of the blade and the shape of the blade reduces velocity of flow over the leading edge; the camber of the blade being maximized midway between the leading and trailing edge. The suction surface of the blade in the region subject to erosion is continuous thereby avoiding discontinuities which form vortices which enhance erosion. Fins, which may be at the tip on the suction side of the blade from midway between the leading and trailing edges to the trailing edge reduces tip vortices thereby further extending blade life in erosion-producing environments.
