  • Publication number: 20120218854
    Abstract: An apparatus for and method of enabling enhanced, selective agitation of liquid containing a solid-phase reagent. The apparatus includes at least one liquid-bearing container, a circular tray, and a motor. The liquid-bearing container(s) includes at least one internal baffle that imparts turbulent agitation to the liquid when flowing from one end of the container to an opposite end. The circular tray is adapted for selective rotation about a vertical axis of rotation. The rotary circular tray assembly includes container-receiving stations that selectively retain a respective liquid-bearing container in an inclined or pitched orientation with respect to a horizontal plane. The motor creates centrifugal force, which causes liquid in the container(s) to travel from the first end of the container to the second end of the container via the internal baffle(s), agitating the liquid and the solid-phase portions of the reagent.

  • Patent number: 7419296
    Abstract: A gel mixing system that employs a dynamic diffuser for quickly removing the air from the fluid as the fluid exits a traditional gel mixer and employs progressive dilution of the gel in a series of hydration tanks to maximize hydration time without allowing the gel to become so viscous that it is not easily diluted or pumped. High shear agitation of the fluid between the hydration tanks helps to increase the hydration rate. Progressive dilution of the gel increases residence time of the gel in the tanks and results in longer hydration time in the limited tank space available, resulting in continuous production of gel that is almost fully hydrated when it is pumped to the fracturing blender and subsequently to the well bore without the need for an increase in the volume of the hydration tanks.

    Abstract: A device (10) for mixing a pulverulent or granular solid (13) with a liquid (32) comprises at least one solid supply device and at least one liquid supply device (37, 38, 40). In an acceleration chamber (42), a rotary movement is imparted to the supplied liquid (32) and the liquid (32) is accelerated to a pre-determined speed, while a rotary movement is imparted to the supplied solid particles (13) in a solid supply chamber (16). The device (10) further comprises a mixing chamber (76) for mixing the solid particles (13) with the liquid (32) to form a suspension, while maintaining the rotary movement generated previously. In a compressor chamber (78), the rotating suspension is accelerated so that a suction effect is generated in an entry region (82) of the compressor chamber (78), which suction effect at least substantially de-aerates the supplied loose solid (13).

  • Patent number: 6997598
    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.

  • Patent number: 6712496
    Abstract: An apparatus and method for dispersing solids into a liquid. The solids may be any particulate material, ranging from cohesive to free flowing. The apparatus and method use an auger to deliver the solids from a hopper to a mixer, where the solids are dispersed into one or more liquids. Typically a vacuum is created in the mixer, or other differential pressures may occur between the hopper and mixer. The apparatus and method provide a delivery rate of the solids which is substantially controlled by the auger rotational speed and substantially independent of the vacuum or other differential pressure at certain auger rotational speeds.
