[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The reactor uses wind and other fluids as auxiliary power during the stirring process. The fluid increases its flow rate under the compression of the air duct, drives the fan turbine through the wind cavity, and the turbine connected to the fan continues to drive the magnetic stirrer in the stirring reaction chamber on the microchannel plate under the action of magnetic force, thereby improving the mixing effect of the reaction materials in the reactor and reducing the system fluid pressure. Increasing the fluid flow rate can make the magnetic stirrer reach thousands or tens of thousands of rotations in the reaction chamber. Under certain conditions, it can inhibit the precipitation of solid matter in the reaction system, and at the same time, it can have a crushing effect on large-particle raw materials, reducing system blockage.

[0020] 2. By installing an ultrasonic generator at the bottom of the reactor, the ultrasonic vibration and airflow can improve the reaction efficiency, increase the reaction speed, inhibit the solid matter precipitated from the fluid, and at the same time break the solid reaction raw materials and clean the attachments in the stirring reaction chamber, reaction microchannel and power wind cavity;

[0021] 3. Compared with the use of electromagnetic coils, when the fluid pressure is sufficient, more stirring reaction chambers can be designed, and high-speed stirring can be achieved more safely. There is no problem of magnetic stirring damage caused by long-term overheating of the instrument. Even if one of the magnetic stirrings is damaged, it has no effect on the system. Usually, it can be restored after flushing with pure water. Since the upper magnetic particles drive the lower magnetic particles, the superposition combination of multiple reaction plates can be easily achieved;

[0022] 4. The stirring directions of adjacent stirring reaction chambers of the reactor are opposite, which improves the mixing, crushing and dispersion effects of the reaction materials. BRIEF DESCRIPTION OF THE DRAWINGS
