The top of reactor body 100 is provided with three material tanks 106, and the bottom of material tank 106 is provided with discharge pipe 107, and discharge pipe 107 is connected with reactor body 100, and the inside of material tank 106 is rotatably connected with shaft 109, and the outer surface of shaft 109 is provided with helical blade 108 inside discharge pipe 107, and the upper surface of three material tanks 106 is provided with second drive mechanism 300 that can simultaneously drive three shafts 109 to rotate.

[0026] In use, first, the raw materials are loaded into the reactor body 100 according to the proportion, and then the three rotating shafts 109 are simultaneously rotated by the second driving mechanism 300. When the rotating shafts 109 rotate, the raw materials in the canister 106 are transported into the reactor body 100 by the spiral blades 108. Then, the stirring shaft 103 and the hollow shaft 101 are simultaneously and non-uniformly rotated by the first driving mechanism 200. The stirring shaft 103 rotates at a high speed and enables the newly added materials to be rapidly involved in the stirring flow field and fully mixed with the existing raw materials, thereby improving the mixing efficiency of the raw materials. The scraper 102 rotates at a low speed and scrapes the raw materials attached to the inner wall of the reactor body 100 and adds them into the mixing reaction.

The centrifugal force generated by the throwing disc 502 can uniformly throw the raw materials collected together to the outside, so that the preliminary mixing of the raw materials can be completed between the stirring, and the overall mixing efficiency and uniformity are improved.

[0031] Specifically, the outer surface of the stirring shaft 103 near the bottom thereof is provided with a movable sleeve 600, the outer surface of the movable sleeve 600 is connected with a connecting plate 601, and the end of the connecting plate 601 is connected with the scraper 102.
