Claims
- 1. A mixing apparatus for agitating and mixing fluids together, said apparatus comprising:
- a casing through the interior of which fluids pass;
- a stationary vane fixedly mounted in said casing and extending inwardly from an inner wall of said casing, said stationary vane comprising a plurality of inwardly extending plate-like members disposed on said inner wall of said casing and spaced axially away from one another at a predetermined distance;
- an agitator movably disposed within said casing, said agitator including a shaft and a fixed vane mounted thereon around the circumference of said shaft, said fixed vane comprising a spiral vane having openings formed therein, each of said openings located out of phase relative to each other without overlapping in the axial direction; and
- a source of oscillation connected with said shaft to oscillate said agitator in the axial direction, whereby said fixed vane can be oscillated while permitting fluids to pass through said casing, thereby creating a relative motion between said fixed and stationary vanes so as to agitate and mix the fluids together,
- wherein each of said plate-like members having an opening formed therein to permit the passage of both the fluids and a portion of said fixed vane, said opening of each of said plate-like members of said stationary vane comprising a central aperture permitting said shaft of said agitator to pass therethrough and a slit-like aperture permitting the passage of said fixed vane therethrough.
- 2. A mixing apparatus for agitating and mixing fluids together, said apparatus comprising:
- a casing through the interior of which fluids pass, said casing comprising a plurality of cylindrical pipe sections stacked one above another having plate-like members between each adjacent pipe sections, wherein each of said plate-like members is a stationary vane fixedly mounted in said casing and extending inwardly from an inner wall of said casing;
- an agitator movably disposed within said casing, said agitator including a shaft and a fixed vane mounted thereon around the circumference of said shaft, said fixed vane comprising a spiral-like vane which is continuous for at least one revolution having agitating elements stacked in the axial direction of said casing and openings formed therein, each of said openings located out of phase relative to each other without overlapping in the axial direction; and
- a source of oscillation connected with said shaft to oscillate said agitator in the axial direction, whereby said fixed vane can be oscillated while permitting fluids to pass through said casing, thereby creating a relative motion between said fixed and stationary vanes so as to agitate and mix the fluids together.
- 3. A mixing apparatus, as defined in claim 2, wherein said plate-like members comprise partitioning plates having a central opening through which said agitating elements pass on assembly or disassembly.
- 4. A mixing apparatus, as defined in claim 2, wherein said plate-like members comprise partitioning plates and said adjacent cylindrical pipe sections comprise axially stacked cylinders having at least one said partitioning plate therebetween.
- 5. A mixing apparatus as defined in claim 2, wherein said partitioning plates are provided with a slit-like opening through which said agitating elements pass on assemblage or disassemblage.
