Abstract
Inside a driven cylindrical housing 23 that is a cylindrical rotation member 13, a liquid to be mixed 4 is caused to become an inner circulation current f by extruded plate portions 24A-24D. Discharge ports 22A-22D formed in the cylindrical housing 21 discharge a portion of the inner circulation current f outward as outer discharge current d1-d4 by centrifugal force. At the same time, the outer portion of the liquid to be mixed 4 is sucked into suction ports 23, 30 as suction current e1-e3, h1-h4, thus mixing the liquid to be mixed 4 in the mixing tank 3.
Claims18
A mixing device for mixing a liquid comprising:
- a drive shaft;
- a mixer body attached to an end of the drive shaft, wherein the mixer body comprises
- a cylindrical rotating member having a cylindrical housing, the cylindrical rotating member is rotatable around a center axis line of the cylindrical housing,
- a top plate, wherein the top plate encloses a top end of the cylindrical housing, wherein the top plate is integrally connected to the end of the drive shaft,
- a plurality of discharge ports disposed in an outer circumferential surface of the cylindrical housing, wherein each of the discharge ports comprises a circumferential edge defined by the cylindrical housing, and
- a plate member protruding inwardly from the circumferential edge of each discharge port, wherein each plate member extends integrally from an inner circumferential surface of the cylindrical housing, and comprises a first and a second major surface in a plane parallel to the center axis line, wherein the first or the second major surface of each plate member is angled about 45 degrees relative to the inner circumferential surface of the cylindrical housing;
- and
- a suction port disposed at a bottom end of the cylindrical housing.

A method for mixing a liquid comprising:
- providing a mixer body comprising
- a cylindrical rotating member having a cylindrical housing, the cylindrical rotating member rotates around a center axis line of the cylindrical housing via a rotating drive shaft connected to a top plate that encloses a top end of the cylindrical housing,
- a plurality of discharge ports disposed in an outer circumferential surface of the cylindrical housing, wherein each of the discharge ports comprises a circumferential edge defined by the cylindrical housing,
- a plate member protruding inwardly from the circumferential edge of each discharge port, wherein each plate member extends integrally from an inner circumferential surface of the cylindrical housing, and comprises a first and a second major surface in a plane parallel to the center axis line, wherein the first or the second major surface of each plate member is angled about 45 degrees relative to the inner circumferential surface of the cylindrical housing;
- a suction port disposed at a bottom end of the cylindrical housing;
- inserting the cylindrical rotating member into a liquid to be mixed;
- and
- rotating the cylindrical rotating member to rotate the plate members, wherein the each plate member draws along the liquid to be mixed that is inside the cylindrical housing to form an inner circulation current, wherein the inner circulation current circulates in one direction to encircle the center axis line, and wherein a portion of the liquid to be mixed, that forms the inner circulation current, is discharged outwardly as an outer discharge current by centrifugal force through the discharge ports at the same time when the liquid to be mixed that is outside of the cylindrical rotating member is sucked into the cylindrical rotating member as suction current via the suction port.
