  • Patent number: 9695670
    Abstract: A slurry mixing system calculates a density of a slurry using measured pressure differential and based on a bulk velocity of the slurry. Slurry from mixing of dry blend and mix fluid enters a one or more tanks having agitators. A pump then pumps the slurry from the tank(s) to the well, and a portion of the slurry is recirculating back to a mixer. From the recirculated path, a direct slurry weight sensor measures a pressure differential of the slurry between two vertical measurement points of a known volume. The sensor can measure a velocity of the recirculated slurry, or the recirculated slurry can be maintained at a velocity. Based on these measures, the controller calculates a density of the slurry, monitors a ratio of the dry blend and the mix fluid, and adjusts the ratio based on the calculated density of the slurry if there is a discrepancy.

  • Patent number: 8905625
    Abstract: The high flow water return fitting of the present invention is designed to connect directly to the end of a water return pipe in a swimming pool, spa, or the like. Water return fittings have been available for many years and have the primary purpose of returning filtered water back into a swimming pool, spa, or the like. However, the water return fitting of the present invention does not only return water into the swimming pool, it also substantially increases the water outflow so that a greater area of water in the pool can be circulated or agitated. The present invention has a uniquely curved nozzle with a flat flange. Both the curvature of the nozzle and the flat flange promote the accumulation of water within the nozzle so as to build up pressure that then pushes the water out a small outlet hole at a greater rate than does a conventional water return fitting. The outflow from the nozzle then creates a low pressure condition within a mixing chamber.

  • Patent number: 8596857
    Abstract: A means for securing a proper mixing of a particle shaped material, such as powder, into a liquid by supplying shear forces in a mixing zone, the shear forces being produced by pumping liquid through a restriction (22), such as a nozzle (27,29) in a pipe at a high pressure. A plurality of nozzles (22) is used, placed in such position with respect to each other that a jet from at least one of the nozzles (22) hits the jet from at least a second nozzle (22) in one single theoretical point downstream of the nozzles (22).

    Abstract: An assembly for the production of dispersions including a mixing unit (7) and a circulation tank (1) for holding liquid, the mixing unit (7) including a first solid inlet (8) for receiving a solid, a second liquid inlet for receiving the liquid, a mixing chamber where the liquid and solid are mixed, and a return outlet (13), the liquid inlet is fluidly connected to the circulation tank (1) such that liquid in the circulation tank flows to the mixing unit (7) via a circulation tank outlet (4), the return outlet (15) transferring the combined liquid and solid from the mixing chamber (7) into the circulation tank (1) via a circulation tank inlet. The circulation tank has an interior height which is configured such that a chamber exists inside the tank above the level of the liquid. Alternatively, the circulation tank inlet is permanently positioned above the liquid level or it includes a pipe configured such that the dispersion forms a film on its inner surface.

  • Patent number: 8511887
    Abstract: A cement mixing method and apparatus for mixing cement used in cementing oil wells casing and the mixer used in that method. The mixer employs a straight bulk cement inlet, five annular recirculation jets and five annular water jet orifices located downstream of the recirculation jets so that all of the jets discharge at an angle towards the mixing chamber and the discharge from the water jet orifices intersects with the flow from the recirculation jets. This five jet, intersecting flow design allows for more thorough wetting of the cement powder with a smaller, lighter, less expensive and more durable mixer that is less inclined to foul and easier to clean.

  • Patent number: 8506810
    Abstract: A process and an apparatus for low-emission storage of biodegradable materials by means of aeration, without aerobic conditions materializing in the material, permits a more consistent feed of the downstream stages in the process. Aeration inhibits methanogenesis and the risk potential of an explosive gas mixture forming in the storage vessel or in the components of the system exhausting waste gas. Closed loop control of the aeration adapts the rate of aeration to the biological activity in the stored material and minimizes air input so as to minimize the loss of methanogenesis potential by aerobic conversion of the matter whilst minimizing the energy required for aeration. The process is characterized in that controlling the aeration in the storage vessel inhibits relevant methanogenesis.

  • Publication number: 20130114368
    Abstract: A horizontal mixer (50) is disclosed. Multiple blades (92) are affixed to and rotate with a tumbler (80) of the mixer (50). These blades (92) extend within an interior mixing chamber (90) and are center-angled so as to promote a desirable mixing action within this chamber (90) (e.g. so as to fold a slurry within the chamber (90) onto itself). One characterization is that the blades (92) are oriented so as to direct a flow toward a common outlet region (78) within the tumbler (80) throughout at least a certain rotational angle. The mixer (50) is particularly suited for realizing a desirable homogeneity of particles within a slurry from which radioisotopes may be produced.

  • Publication number: 20130083620
    Abstract: A method and system for controlling an interface emulsion layer and mud layer within a desalter vessel includes injecting a water flow through a plurality of nozzles arranged about a piping circuit located in the brine water layer. Each nozzle is oriented toward an interior space of the desalter vessel and is arranged oblique to the piping circuit. The water flow through the plurality of nozzles causes a horizontal and vertical rotation of a volume of water that is effective for suspending solids in the water and promoting a collapse of the interface emulsion layer. The water flow through each nozzle, which may be a recycled water flow, is preferably in a range of 1 to 3 fpm and each nozzle is preferably oriented at an angle of about 15° and 60° in a horizontal plane and a downward angle of about 15° and 60° in a vertical plane.
