    Abstract: A high-speed turbine mixer combines water and cement into a pre-mixed cement paste that is added to aggregates to create a concrete mix. The turbine mixer includes a housing that cooperates with an auger to move dry cement into a mixing chamber where water is added. A mixing plate rotates at high speed to break up water and cement into small particles that enhances the hydration of the cement and increases the air content in the resultant cement paste. The cement paste is then conveyed to a mixing auger to be combined with aggregates to create a concrete mix. The mixing plate divides the mixing chamber to force the mixing water and cement particles to pass through a circumferential annular opening past agitating fins. Admixtures can be added to the cement as a powder or to the water as a liquid for incorporation into the cement paste.

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.

  • Publication number: 20040218464
    Abstract: A method and apparatus for blending liquids with solid particulate matter in which a center drive shaft extends through a housing having a solid particle inlet and a liquid inlet together with an outlet, and upper and lower impeller vanes are aligned respectively with the particle inlet and liquid inlet to cause intermixing of the solids and liquids by counterflow of the liquid into the upper impeller region. In one embodiment, expeller blades are employed in inner concentric relation to the upper impeller vanes to accelerate the flow of solid particles into the upper impeller region, and baffle plates or deflector members are employed above and below the upper and lower impellers to prevent any leakage of liquid into the center of the impeller. In preferred and alternate forms, the impeller vanes are sized to balance the point at which the solids and liquid are intermixed.

  • Publication number: 20040062144
    Abstract: The invention relates to a mixing apparatus and a method for mixing gas in a closed mixing reactor, which uses gas as a process chemical with a high efficiency and where the content of pulverous solids in the solution is great. The aim is to obtain a flow in the reactor which sucks gas from above the surface of the liquid using rotating mixing devices in the centre of the reactor, and to mix said gas throughout the reactor capacity. The mixing apparatus of the invention comprises at least two mixers located at different heights, and on the same shaft. The upper mixer is equipped with a central plate attached to the shaft, with essentially vertical inner blades rising upwards and downwards and outer vanes directed outwards from the central plate, which are inclined from the horizontal. The lower mixer is equipped with a central plate attached to the shaft with vertical blades located on the outer edge.

  • Publication number: 20030202421
    Abstract: An impact-type rotary fining, homogenizing and emulsifying device is constituted by a casing body disposed on a base, a feed port and a discharge port disposed in the casing body, and a power shaft disposed inside of the casing body. The power shaft is equipped with rotary impellers in such a manner that the rotary impellers are disposed on the power shaft and include a first rotary impeller rotated in a positive direction and a second rotary impeller rotated in negative direction. A power shaft portion is located in the feed port and is equipped with a feed impeller. A valuable advantage is obtained in that its new and distinct structure and innovative design enable the device to heighten the impact velocity applied to treated materials many fold, without raising the rotating speed of the impellers. Functions of fining, homogenizing and emulsifying are improved, while effectively enhancing the overall performance of the apparatus, within the motor's allowable rotational speed.

    Abstract: A rotor to establish a swirling flow in liquid(s) contained in a vessel. In one form the rotor includes two parallel spaced apart discs. An array of vanes is interposed between the discs. One of the discs is annular to define an inlet to the array of vanes. The inlet controls the size of an inner core region of the swirling flow. In another form the rotor has at least two hollow spokes directed radially outwardly from the central hub. The spokes each have a passage with an inlet directed toward the hub and a radially directed outlet. Rotation of the rotor produces a flow through the spokes that contributes to the rotational radially outward flow that establishes the swirling flow. In another form of the invention the rotor includes at least two blades directed radially outwardly from a central hub. The blades include at least one surface inclined to the direction of rotation of the rotor.
