Abstract
A mixer for mixing multi-phase fluids with various substances. The mixer includes a rotor with a plurality of blades extending within a chamber through which the multi-phase fluids and substances continuously flow while being mixed. The chamber of the mixer includes a single rib for generating turbulence and may be eccentrically located with respect to the axis of rotation of the rotor. In addition, the rotor blades and the rib may be separately angled with respect to the axis of rotation of the rotor.
Claims28
A mixer for mixing at least two substances, said mixer comprising:
- a mixer casing having an inlet and an outlet, each having an opening and a center axis which extends axially through the center of the opening, said inlet for receiving a stream of unmixed substances under pressure;
- a motor, including a rotatable shaft, adapted to be mountable on said mixer casing;
- a rotor mounted on said rotatable shaft for rotation about an axis of rotation and including a plurality of elongated blades which extend at least partially in a direction perpendicular to the center axis of said inlet or said outlet;
- and,
- a mixing chamber housing said rotor and defined in part by an inner surface of said mixer casing, said inner surface having a contour which is in closer proximity to said blades on one side of said rotor than on a generally opposite side of the rotor, said inner surface and said blades of said rotor thereby defining respective regions of lesser and greater clearance between each other, said mixing chamber further including an elongated rib protruding from the inner surface of said mixer casing in said region of greater clearance and extending at least partially in a direction perpendicular to the center axis of said inlet or said outlet.

A mixer for mixing substances, said mixer comprising:
- a mixer casing having an inlet and an outlet, each having an opening and a center axis which extends axially through the center of the opening, said inlet receiving a stream of unmixed substances under pressure;
- a mixing chamber defined in part by an inner surface of said mixer casing and in communication with said inlet for receiving said unmixed substances from said inlet, said mixing chamber including a fixed elongated rib protruding from the inner surface of said mixer casing and extending at least partially in a direction perpendicular to the center axis of said inlet or said outlet;
- and,
- an open rotor mounted on a shaft and rotatably disposed within the mixing chamber, the shaft arranged substantially perpendicular to the center axes of said inlet and said outlet of said mixer casing and defining an axis of rotation for said rotor, said open rotor including a plurality of spaced blades, each blade extending at least partially in a direction perpendicular to said stream of unmixed substances, each blade also disposed radially outside of and being spaced away from the axis of rotation such that a substantially completely open space is defined near the axis of rotation of said rotor through which said stream of unmixed substances may flow, said blades interacting with said elongated rib to generate turbulence within said mixing chamber whereby said stream of unmixed substances is substantially homogeneously mixed before moving into said outlet of said mixer casing.

A mixer for mixing substances, said mixer comprising:
- a mixer casing having an inlet and an outlet, each having an opening and a center axis which extends axially through the center of the opening, said inlet receiving a stream of substantially unmixed substances under pressure;
- a mixing chamber defined in part by an inner surface of said mixer casing and for receiving said unmixed substances from said inlet, said mixing chamber including a smooth and continuous region corresponding to said inner surface and a fixed elongated rib protruding from said inner surface which extends at least partially in a direction perpendicular to the central axis of said inlet or said outlet;
- and,
- an open rotor mounted on a rotatable shaft and rotatably disposed within the mixing chamber, the shaft arranged substantially perpendicular to the central axes of said inlet and said outlet of said mixer casing and defining an axis of rotation for said rotor, said open rotor including a plurality of spaced blades extending at least partially in a direction perpendicular to said stream of unmixed substances, each individual blade disposed radially outside of and being spaced away from the axis of rotation such that a substantially completely open space is defined near the axis of rotation of said rotor through which said stream of unmixed substances may flow, each individual blade interacting with said smooth and continuous region of said mixing chamber while moving in a direction opposite the overall flow of said substances from said inlet of said mixer casing to said outlet, each individual blade also interacting with said elongated rib while moving in a direction of the overall flow of said substances to generate substantial turbulence in said substances while tending to facilitate the overall flow of substances through the mixing chamber.
