Abstract
A stirrer is provided such that a fluid being processed can be more efficiently shown by way of the action of an intermittent jet flow and processing capacity can be improved. The stirrer concentrically includes a rotor that includes a plurality of flat vanes and that rotates, and a screen that is place around the rotor. The screen includes a plurality of slits in the circumferential direction thereof, and screen members that are positioned between adjacent slits. The fluid being processed is discharged by rotation of the rotor from the inside of the screen to the outside as an intermittent jet flow through the slits. The width of the distal working face on the distal end of the vane in the rotational direction is smaller than the width of the basal end of the vane in the rotational direction.
Claims20
A stirrer, comprising:
- a rotor having a plurality of plate-like blades and rotating, 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 includes a plurality of slits in a circumferential direction and a screen member located between the adjacent slits,
- wherein in the stirrer, in which by rotating at least the rotor of the rotor and the screen, a fluid to be processed is discharged as an intermittent jet flow from the inside of the screen to the outside through the slits, and
- wherein a width of a front-end action surface in a front-end part of the blade in the rotation direction is narrower than a width of a base-end part of the blade in the rotation direction.
A stirrer, comprising:
- a rotor having a plurality of plate-like blades and rotating, and a screen laid around the rotor, all of which are provided concentrically,
- wherein the screen includes a plurality of slits in a circumferential direction and a screen member located between the adjacent slits,
- wherein in the stirrer, in which by rotating at least the rotor of the rotor and the screen, a fluid to be processed is discharged as an intermittent jet flow from the inside of the screen to the outside through the slit,
- wherein the plurality of the plate-like blades rotationally moves by the rotation of the rotor,
- wherein on the front surface side of the blade in the rotation direction, by increasing a pressure of the fluid to be processed, the fluid to be processed is discharged as an intermittent jet flow from the slit located in the front surface side of the blade,
- wherein on the back surface side of the blade, by decreasing the pressure of the fluid to be processed, the fluid to be processed is sucked from the slit located in the back surface side of the blade,
- wherein the front-end part of the blade is defined by the frontend action surface and a flank surface,
- wherein the front-end action surface is a surface which is provided on the very front-end of the blade such that the distance between the front-end action surface and the inner wall surface of the screen is kept minute distance,
- wherein the flank surface is a surface which is located behind the front-end action surface in the rotation direction of the blade and is provided such that the distance between the flank surface and the inner wall surface of the screen is larger than the minute distance, and
- wherein the blade is configured so as to be faster a suction velocity of the fluid to be processed by being provided with the flank surface on the front-end part as compared with the case that the flank surface is not provided on the front-end part.
