Patent ID: 10478790

Abstract:
The problem of providing a stirrer capable of more effectively shearing a fluid to be treated is addressed, by using the action of an intermittent jet stream. A stirrer is provided with a rotor having a blade and a screen, which are relatively rotated such that the fluid to be treated is discharged from the inside of the screen to the outside as an intermittent jet stream through a slit in the screen, the stirrer satisfying condition 1 and condition 2. (Condition 1) the relationship among the width b in the rotating direction of a tip part of the blade, the width s in the circumferential direction of the slit, and the width t in the circumferential direction of the screen member is b≥2s+t. (Condition 2) the relationship between the width b in the rotating direction of the tip part of the blade and the maximum inner diameter c of the screen is b≥0.1c.
