Abstract
The invention discloses a high-speed stirring device which comprises a stirring container, a stirring wheel and a stirring shaft. A conical stirring tank is arranged in the stirring container; concave-convex staggered inclined grooves are formed in the inner surface of the stirring tank; the stirring wheel which is the conical stirring wheel is arranged in the stirring container and is concentric with the stirring tank; the stirring shaft which can positively and negatively rotate at a high speed is connected to the middle of the conical stirring wheel; the conical stirring wheel is driven to rotate by the stirring shaft. When in use, the conical stirring wheel is driven to rotate at a high speed by the stirring shaft which rotates at a high speed, a processed liquid which is introduced from the bottom part of the stirring container rises along the barrel wall of the stirring tank and the conical stirring wheel, aggregates are dispersed and uniformly stirred under the interaction between the stirring tank and the conical stirring wheel, and then the processed liquid is fed into a material-discharging cavity and is discharged through a material-discharging pipe. Through the arrangement of the concave-convex staggered inclined grooves in the inner surface of the stirring tank, the action of the processed liquid is more intense and disordered in the interaction process, and thus a better dispersing effect is achieved.
