The stirring blades are a circle of axial flow type blades which are uniformly distributed along the circumferential direction of the vertical stirring shaft.

The utility model has the advantages that:

(1) the rotary mesh screen is arranged in the mixing tank, the rotary mesh screen firstly rotates and scatters powder fed into the mixing tank, the problem that the powder is agglomerated when the powder subsequently enters liquid is avoided, and the rotary mesh screen is of an olive-shaped structure, so that the powder is more easily dispersed and prevented from agglomerating when entering the olive-shaped structure for rotary shaking compared with a plate-shaped mesh screen, and the olive-shaped structure is more easily landed and dispersed for rotary shaking compared with a spherical mesh screen, so that the uniform mixing is facilitated;

(2) the stirring mechanism of the utility model pre-stirs the liquid on one hand and realizes the uniform mixing and stirring of the powder on the other hand; wherein, stirring vane is fixed in vertical (mixing) shaft's upper portion, makes the powder drive by stirring vane when getting into liquid, can not appear condensing the problem of blocking, and the stirring impeller is fixed in vertical (mixing) shaft's bottom, forms whirlpool vortex flow field, further improves the homogeneity of compounding.

The utility model has simple structure and reasonable design, ensures that powder materials are added into liquid and mixed evenly by matching the transversely arranged rotary mesh screen and the longitudinally arranged stirring mechanism, avoids the problem of powder caking and ensures the quality of mixed material finished products.
