US 9,004,743 B2 · Mixing device for creating an output mixture by mixing a first material and a second material

Abstract

A mixing device for mixing a first and second material together to create an output mixture. The device includes a first chamber containing the first material coupled to a mixing chamber defined between a rotor and a stator. The rotor is disposed inside the stator and rotates therein about an axis of rotation. The first chamber houses an internal pump configured to pump the first material from the first chamber into the mixing chamber. The pump may be configured to impart a circumferential velocity into the first material before it enters the mixing chamber. At least one of the rotor and stator have a plurality of through-holes through which the second material is provided to the mixing chamber. Optionally, a second chamber is coupled to the mixing chamber. The second chamber may house an internal pump configured to pump the output material from the mixing chamber into the second chamber.

Dependent claims

A mixing device for creating an output mixture by mixing a first material and a second material, the device comprising:

a first chamber configured to receive the first material from a source of the first material;
a stator;
a rotor having an axis of rotation, the rotor being disposed inside the stator and configured to rotate about the axis of rotation therein, at least one of the rotor and stator having a plurality of through-holes;
cylindrical mixing chamber defined between the rotor and the stator, the cylindrical mixing chamber being in fluid communication with the first chamber and configured to receive the first material therefrom, and to receive the second material into the cylindrical mixing chamber via the plurality of through-holes formed in the at least one of the rotor and stator;
and
a first internal pump housed inside the first chamber, the first internal pump being configured to pump the first material from the first chamber into the cylindrical mixing chamber.

3 more elements

A method of mixing a first material and a second material in mixing chamber formed between two contoured surfaces to create an output mixture, the mixing chamber having a first end portion opposite a second end portion, the method comprising:

introducing the first material into the first end portion of the mixing chamber in a flow direction having a first component that is substantially tangent to the mixing chamber and a second component that is directed toward the second end portion;
and
introducing the second material into the mixing chamber though at least one of the two contoured surfaces between the first end portion of the mixing chamber and the second end portion of the mixing chamber.
