[0018] The following is in conjunction with the appendix Figure 1-5 The embodiments of the present invention will be described in detail.

[0019] A reaction vessel includes a vessel body 1, which is cylindrical with a tapering bottom. A stirring motor 2 is positioned at the upper center of the vessel body 1, driving a main stirring shaft 3. Several main stirring blades 4 are connected to the bottom side of the main stirring shaft 3. Several vertically arranged guide grooves 6 are evenly distributed on the outer side of the main stirring shaft 3. Lifting blocks 5 are positioned on the outer periphery of the main stirring shaft 3 corresponding to the guide grooves 6. Guide blocks 7 are connected to the inner side of the lifting blocks 5 and are positioned within the guide grooves 6. The cooperation between the guide grooves 6 and guide blocks 7 restricts the movement of the lifting blocks 5 along the outer wall of the main stirring shaft 3. An upper mounting ring 9 and a lower mounting ring 11 are connected to the main stirring shaft 3 above and below the guide grooves 6, respectively. An upper spring 10 connects the upper mounting ring 9 to the lifting blocks 5, and a lower spring 12 connects the lifting blocks 5 to the lower mounting ring 11. Under the action of the upper spring 10 and the lower spring 12, the lifting blocks 5 maintain a balanced state and are not easily shaken. A support rod 15 is connected to the outside of the lifting block 5. A secondary stirring shaft 16 is provided at the lower part of the support rod 15. Several secondary stirring blades 17 are connected to the lower part of the outer side of the secondary stirring shaft 16. An installation groove 18 is opened inside the support rod 15. A slide rail 20 is provided inside the installation groove 18. A slider 21 is slidably arranged on the slide rail 20. A hydraulic cylinder 22 is provided inside the installation groove 18. The piston rod of the hydraulic cylinder 22 is connected to the slider 21. An extension rod 19 is provided at the outer position inside the installation groove 18. A connecting rod 28 is connected between the slider 21 and the extension rod 19. A moving wheel 29 is rotatably arranged at the outer end of the extension rod 19. A guide ring 13 is provided on the inner wall of the vessel body 1. A guide rail 14 is provided at the middle position of the guide ring 13.

[0020] In the first working state, the moving wheel 29 is not within the guide rail 14. The stirring motor 2 drives the main stirring shaft 3 to rotate, which in turn drives the main stirring blade 4 and the support rod 15 to rotate. The main stirring blade 4 stirs the material at the bottom of the vessel body 1. The support rod 15 drives the auxiliary stirring shaft 16 to rotate, which in turn drives the auxiliary stirring blade 17 to rotate, and the auxiliary stirring blade 17 stirs the material in the middle part of the vessel body 1.

[0021] In the second working state, the hydraulic cylinder 22 controls the extension of its piston rod, causing the slider 21 to move outward along the slide rail 20, thereby pushing the extension rod 19 outward. The moving wheel 29 on the extension rod 19 just enters the guide rail 14 inside the guide ring 13. At this time, when the main stirring shaft 3 drives the support rod 15 to rotate, the moving wheel 29 moves within the guide rail 14. The guide rail 14 includes an ascending section, a descending section, and a horizontal section, which are alternately arranged to form an arc-shaped trajectory. The transitions between each section are made by circular arcs to ensure the normal passage of the moving wheel 29. The moving wheel 29 moves along this arc-shaped trajectory, which drives the support rod 15 to rise and fall synchronously, and then drives the auxiliary stirring blade 17 to move up and down. The auxiliary stirring blade 17 moves up and down while rotating, which expands the stirring area of ​​the auxiliary stirring blade 17 and can mix materials located at different heights, making the materials more evenly stirred.

[0022] Preferably, four lifting blocks 5 are provided, evenly distributed around the outer periphery of the main stirring shaft 3. A certain gap is left between each lifting block 5 to avoid mutual interference during the lifting process.

[0023] Preferably, a guide rod 8 is connected between the upper mounting ring 9 and the lower mounting ring 11, and the guide rod 8 passes through the lifting block 5. By setting the guide rod 8, the lifting of the lifting block 5 is further limited to ensure the vertical lifting of the lifting block 5, and to prevent the lifting block 5 from deflecting, which would cause the moving wheel 29 to deflect within the guide rail 14 and prevent the moving wheel 29 from rotating normally, thereby affecting the normal operation of the entire device.

[0024] Preferably, the support rod 15 has a notch 24 at its lower part, and limit strips 31 are provided on the front and rear side walls of the notch 24. The upper end of the auxiliary stirring shaft 16 extends through the notch 24 into the mounting groove 18. The portion of the auxiliary stirring shaft 16 located in the notch 24 has a groove that mates with the limit strips 31. A gear ring 26 is connected to the upper end of the auxiliary stirring shaft 16. A drive motor 25 is installed in the mounting groove 18, and the drive motor 25 drives a drive gear 27 connected to it. The drive gear 27 meshes with the gear ring 26. The drive motor 25 drives the drive gear 27 to rotate in both directions. The drive gear 27, through meshing with the gear ring 26, drives the auxiliary stirring shaft 16 to swing back and forth in the notch 24, thereby causing the auxiliary stirring blade 17 to swing. The auxiliary stirring blade 17 can produce different stirring effects at different angles. In both working states, the drive gear 27 always remains meshed with the gear ring 26. In both working states, the auxiliary stirring shaft 16 can be driven to swing to change the position of the auxiliary stirring blade 17 at any time.

[0025] Preferably, the drive motor 25 is installed on the right side of the lower part of the slider 21, and a limit block 23 is provided on the left side of the lower part of the slider 21.

[0026] The width of the gear ring 26 is much larger than the width of the drive gear 27, and the width of the guide rail 14 is much larger than the width of the moving wheel 29. This arrangement allows for another working state. In working state three, based on working state two, the hydraulic cylinder 22 controls its piston rod to extend further, pushing the slider 21 to continue moving to the right. At this time, the drive gear 27 disengages from the gear ring 26, while the limiting block 23 contacts the gear ring 26. The limiting block 23 fixes the position of the gear ring 26, keeping the auxiliary stirring shaft 16 at a certain angle, and the position of the auxiliary stirring blade 17 is also fixed.

[0027] Preferably, a baffle 30 is connected to the upper end of the auxiliary stirring shaft 16, and a toothed ring 26 is installed on the upper part of the baffle 30. The size of the baffle 30 is larger than the size of the notch 24, and the baffle 30 can always cover the notch 24 when the auxiliary stirring shaft 16 swings, thereby preventing material from entering the mounting groove 18 inside the support rod 15 from the notch 24.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
