Abstract

A stirrer is provided that can more efficiently achieve shearing applied, by an action of an intermittent jet flow, to a fluid to be processed. The stirrer concentrically includes a rotor including a blade, a partition wall, and a screen, wherein: the screen includes a plurality of slits in a circumferential direction thereof and screen members located between the adjacent slit; by rotating at least the rotor of the two components, the fluid to be processed is discharged from the inside to the outside of the screen as the intermittent jet flow through the slit of the screen; the screen has a cylindrical shape having a circular cross section; an opening of the slit provided on the inner wall surface of the screen is used as an inflow opening; openings of the plurality of slits provided on the outer wall surface of the screen are used as outflow openings; and the width of the outflow openings in the circumferential direction is set to be smaller than the width of the inflow opening in the circumferential direction.

Dependent claims

A stirrer, comprising:

a rotor having a plurality of blades and being mounted for rotation, a partition wall for holding a discharge pressure of the rotor, and a screen laid around the rotor, all of which are provided concentrically,
wherein the screen comprises a plurality of slits extending in an axial direction and spaced apart from each other in a circumferential direction of the screen and a screen member located between the adjacent slits,
wherein in the stirrer, by rotating at least the rotor, a fluid to be processed is discharged as an intermittent jet flow from an inside of the screen to an outside of the screen through the plurality of slits,
wherein the screen forms a cylindrical shape having a circular cross-section,
wherein an opening of the plurality of slits provided on an inner wall surface of the screen is made to serve as an inflow opening, and an opening of the plurality of slits provided on an outer wall surface of the screen is made to serve as an outflow opening, and
wherein a width of the outflow opening in the circumferential direction is set to be narrower than a width of the inflow opening in the circumferential direction.
