  • Patent number: 8875903
    Abstract: A system to facilitate separation and concentration of particles based on centrifugal force on suspended particles, including biological matter, which are made to flow in a vortex structure is provided. The centrifugal force urges larger particles to collect along outer portions of the vortex flow. Conversely, within a vortex structure, a radial hydrodynamic pressure drop is also amplified to urge smaller particles toward inner portions of the vortex flow. This force created by the pressure can reach magnitudes that encourage a sharp cut-off and improved resolution discrimination between particle sizes. Thus, separated streams of particles can be collected with both increased concentration and purification.

The inserts [872B] comprise a hard material (e.g., ceramic or carbide) and form wear bodies which slow and dissipate kinetic energy of escaping slurry by way of creating paths of resistance. As the suspension matrix [872A] erodes over time, a plurality of interstices [872C] between the inserts [872B] are formed.

    Abstract: The induced vortex particle separator is a device for separating solid particulate matter from a liquid containing such particulate matter. The liquid enters a housing through an inlet port and is driven about a helical vane to form a helical flow path. Upon exiting the helical vane, the liquid is received within a central portion of the housing where a centralized structure including an annular stator and an inverted diffuser cone drive the liquid to form a free vortex. Under centrifugal force, the solid particulate matter is separated from the liquid and flows, under the force of gravity, into a lower region of the housing. Due to a negative pressure differential, the liquid is driven upwards within an inner cylindrical shell mounted within the housing to flow into a siphon for output through an outlet port.

  • Patent number: 7900779
    Abstract: Particle classifier (2) for separating solid particles in a flow of gas and particles (1) into two fractions depending on size by means of gravitation force, air resistance force and applied centripetal force. A mixture of gas and particles is charged well dispersed to a classifier inlet zone (3) from which the mixture is brought into contact with a rotor (6) in a first separation zone (5) having the form of a free rotor chamber. Gas and fine particles are allowed to escape through an upper outlet (9) while the coarse fraction of the particles is forced to pass through a second separation zone and subsequently to leave through a lower outlet (15).

  • Patent number: 7896169
    Abstract: A variety of improved hydroclone based fluid filtering systems are described. The hydroclones generally include a tank having an internal chamber and a filter (preferably a surface filter) that is positioned within the internal chamber. The filter defines a filtered fluid chamber within the internal chamber of the tank. The hydroclone may be operated such that a vortex of flowing fluid is formed between the chamber wall and the filter with the filter being located in the center of the vortex. With this arrangement, the filter acts as a cross-flow filter. In one aspect of the invention, the filter is a stepped filter. In another aspect of the invention, the filter is an surface filter, as for example, an electroformed metal surface filter. In some preferred embodiments, the openings in the filter are arranged as slots that extend substantially vertically so that they are oriented substantially perpendicular to the flow path of fluid flowing in the adjacent portion of the vortex.

  • Publication number: 20100200474
    Abstract: A hindered-settling fluid classifier is adapted for processing material aggregate in a liquid medium. The fluid classifier includes a classifier tank defined by walls designed for holding the liquid medium, and comprising a sink fraction chamber and a float fraction chamber, and a fluid inlet and a fluid outlet. An elongated rising current column is vertically mounted within the sink fraction chamber, and adapted for extending below a surface of the liquid medium held therein. The rising current column has open upper and lower ends, and defines an aggregate entry between its upper and lower ends for receiving material aggregate into the classifier tank. A float fraction reservoir is located above the sink fraction chamber, and communicates with the open upper end of the rising current column. An overflow passage communicates with the float fraction reservoir, and is adapted for directing the liquid medium outwardly from the reservoir and into the float fraction chamber.

  • Patent number: 7708146
    Abstract: A hydrocyclone can be used for separating components of a fluid. The hydrocyclone can include a substantially open cylindrical vessel and a helical confined path connected upstream of the cylindrical vessel. The open vessel can include an open vessel inlet configured to introduce a fluid tangentially into the open vessel. The helical confined path can be connected to the open vessel at the open vessel inlet. One or more wash inlets can be used to introduce a wash fluid into the helical confined path and/or the open vessel. An overflow outlet and underflow outlet can be operatively attached to the open vessel for removal of the separated fluid components. Although a number of fluids can be effectively treated, de-sanding of bitumen slurries from oil sands can be readily achieved.

  • Patent number: 7429327
    Abstract: Methods and apparatus for separating solid particles from a fluid. One preferred embodiment includes a tank for settling particles out of the fluid, a conical chamber at the bottom of the tank, an outlet connected to conical chamber, and a conical auger within the conical chamber. The tank may have a tangential inlet that creates a fluid circulation that exerts a centrifugal force on the solid particles to increase the settling of particles out of the fluid. The tank may have a static spiral on the inner wall that helps small particles coalesce into larger particles that settle faster out of the fluid. The fluid content of the solids removed from the tank may be controlled by varying the rotational speed of the conical auger. The rotational speed of the conical auger may be varied depending on the torque required to rotate the conical auger.

    Abstract: A hydrocyclone unit for separating a fibre pulp suspension containing relatively heavy contaminants has an elongate tapering separation chamber, an inlet member that feeds the suspension tangentially into the separation chamber at a base end, so as to form a vortex in the separation chamber, a reject fraction outlet at the apex end of the separation chamber for discharging a reject fraction containing heavy contaminants, and a central accept fraction outlet at the base end for discharging a central fraction containing fibres. A fluid injection member is adapted to inject a fluid tangentially into the separation chamber at a distance from the apex end which is at least 40% of the length of the separation chamber, such that the injected fluid increases the rotational speed of a portion of the vortex in the chamber to increase the separation efficiency with respect to fibres existing in the vortex portion.
