Abstract
A continuous flow mixer includes an impeller assembly and a mixing chamber formed from concentric inner and outer tubes. The inner tube is radially constrained but is movable along the axis of the outer tube. The impeller assembly is at one end of the mixing chamber and draws fluid along the interior of the inner tube and discharges the fluid to the annular region between the inner and outer tubes. The fluids are introduced into the mixing chamber at the end remote from the impeller assembly and the mixed solution exits the mixing chamber substantially centrally of its length from the annular region.
Claims11
Apparatus for mixing a first material with a fluid solvent, comprising:
- a hollow generally cylindrical outer casing having a first open end and a second open end;
- first sealing means for sealing said first open end of said outer casing;
- second sealing means for sealing said second open end of said outer casing;
- a hollow generally cylindrical inner tube having a first open end and a second open end, said inner tube having a length less than the length of said outer casing and exterior cross sectional dimensions less than the interior cross sectional dimensions of said outer casing;
- an impeller assembly mounted to said first sealing means inside said outer casing, said impeller assembly having an inlet port substantially centrally of said outer casing and at least one discharge port directing discharged fluid outwardly toward said outer casing;
- support means for supporting said inner tube within said outer casing between said impeller assembly and said second sealing means so as to maintain a generally annular region between said inner tube and said outer casing, said support means having means for allowing axial movement and constraining radial movement of said inner tube, with said inner tube first open end being closely adjacent said impeller assembly and there being a space between said inner tube second open end and said second sealing means;
- first inlet means for introducing said first material to the interior of said outer casing;
- second inlet means for introducing said fluid solvent to the interior of said outer casing;
- and
- an outlet extending through said outer casing between said outer casing first and second ends and communicating with said annular region.
