The output end of the motor 4 extends through the frame 3 into the reactor body 1 and is fixedly installed with a stirring mechanism 5. The stirring mechanism 5 also includes a stirring shaft 6, two connecting blades 7 fixedly installed at the lower end of the stirring shaft 6, a first stirring blade 8 fixedly installed between the two connecting blades 7, a sleeve 9 movably installed on the outside of the stirring shaft 6, a fixing ring 10 fixedly installed on the outside of the sleeve 9, two semi-circular mounting rings 11 movably installed on the outside of the fixing ring 10, and a second stirring blade 12 fixedly installed on both sides of the two semi-circular mounting rings 11.

[0028] like Figures 2-3 As shown, two limiting shafts 13 are fixedly installed at the top of the reactor body 1. The axial movement of the sleeve 9 can be restricted by the two fixed limiting shafts 13. A double spiral groove 14 is provided on the outside of the stirring shaft 6.

[0029] like Figures 2-5As shown, a socket 15 is provided in the center of the sleeve 9. Shaft holes 19 are provided on both sides of the fixing ring 10 near the sleeve 9. A connecting mounting hole 16 is also provided on one side of the sleeve 9 and the fixing ring 10. Positioning grooves 20 are provided on both sides of the fixing ring 10 within the mounting hole 16. A rotating shaft 17 is rotatably mounted in the mounting hole 16. A positioning block 21 is fixedly mounted between the two positioning grooves 20. A guide block 18 is fixedly mounted on one side of the rotating shaft 17. A stop 22 is fixedly mounted on the positioning block 21 relative to the side of the rotating shaft 17, with one side of the stop 22 abutting against the side of the rotating shaft 17. The socket 15 is inserted into the stirring shaft 6, and the shaft hole 19 is inserted into the corresponding limiting shaft 13. The guide block 18 is slidably connected in the double spiral groove 14. With the help of the sleeve 9, rotating shaft 17, and guide block 18, the limiting shaft 13 can be used to achieve synchronous control when the stirring shaft 6 rotates to connect the impeller 7 and the first stirring impeller 8. The sleeve 9 has a reciprocating lifting function. The upper and lower ends of the semi-circular mounting ring 11 are provided with multiple guide grooves to prevent the medium from remaining in the cavity between the semi-circular mounting ring 11 and the sleeve 9. A side blade 23 is fixedly installed on one side of the second stirring blade 12. The side blade 23 has multiple through grooves. A clamping block 24 is fixedly installed on the side of the second stirring blade 12 away from the semi-circular mounting ring 11. Multiple balls are rotatably installed in the clamping block 24. The two semi-circular mounting rings 11 are fixedly connected to each other by bolts and rotate on the fixed ring 10.

It works with the first stirring blade 8 to drive the two sets of second stirring blades 12 and side blades 23 to rotate, thereby agitating the medium in the reactor body 1 and improving the mixing efficiency between the media.

[0030] It should be noted that this utility model is a high-efficiency antioxidant production reactor. When the medium and auxiliary materials in the reactor body 1 are stirred and mixed, the motor 4 is started by the external main controller. Then, the output end of the motor 4 drives the stirring shaft 6 to rotate. The stirring shaft 6 can drive the first stirring blade 8 to rotate through the two connecting blades 7. Since the two adjacent second stirring blades 12 are clamped to one side of the first stirring blade 8 by the clamping block 24 on one side, the first stirring blade 8 synchronously drives the second stirring blades 12 to rotate, thus stirring and mixing the medium in the reactor body 1. Meanwhile, since the fixing ring 10 passes through the two shaft holes 19 between the two limiting shafts 13, it can restrict the axial movement of the sleeve 9. The stirring shaft 6 also rotates inside the sleeve 9 and slides on the guide block 18 with the help of the double helical groove 14, so that the sleeve 9 moves up and down on the outside of the stirring shaft 6. Thus, the sleeve 9 drives the two semi-circular mounting rings 11 to move up and down synchronously through the fixing ring 10, so that the second stirring blade 12 can move up and down as it follows the rotation of the first stirring blade 8, thereby achieving full mixing of the upper and lower layers of the medium in the reactor body 1.
