The stirring device is widely used in chemical, food, pharmaceutical and other industries. The types of stirring devices include blenders, stirring tanks, stirring barrels, stirring rods, stirring tubes and stirring drums.

[0003] A Chinese patent with application number CN201921320319.7 discloses a stirring device for a stirring tank, including a tank body, the top of which is fixedly connected to a driving motor by bolts, a driving shaft is fixedly mounted on the output shaft of the driving motor, a driving hole is opened on the top of the tank body, the driving shaft is rotatably mounted in the driving hole, and a plurality of groups of stirring blades are fixedly mounted on the outer side of the driving shaft.

[0004] The above scheme adds materials into the tank body through the feed port and then mixes the materials through the stirring blades. However, in actual use, the materials are added into the tank body through the feed port, and the diffusion distance of the materials from top to bottom is long and the diffusion speed is slow, resulting in slow mixing of the materials and the reaction solvent and low mixing efficiency.

[0005] In view of this, the present utility model is proposed. Utility Model Content
