[0038] Method of use of the present invention:

[0039] First of all, it should be made clear that the mixing tower involved in the present invention is mainly used for mixing operations of various types of liquid materials. The present invention takes the mixing of liquid raw materials for refrigerants as an example to explain its method of use in detail.

The dragon 233 realizes the upward conveying and stirring of the material at the lower part of the tower body 100, thereby realizing the all-round and multi-angle stirring and mixing operation of the material in the tower body 100. The rotation of the auger blades of the conveying auger 300 realizes the upward conveying of the liquid in the lower part of the tower body 100 during the stirring process, and cooperates with the rotating high-efficiency stirring mechanism 200 to realize the efficient stirring operation of the material in the tower body 100. The present invention can drive the stirring impeller group to realize the multi-directional and full-angle efficient stirring operation of the material in the tower body 100 by the rotating high-efficiency stirring mechanism 200 set in the tower body 100, which solves the problem that the stirring method of the material in the traditional mixing tower only relies on the stirring blades set on the outer side of the stirring rod 210 for unidirectional rotation stirring, and the stirring efficiency is low, the stirring effect is poor, and the mixing efficiency of the mixing tower is low.
