[0030] Example 1:

[0031] refer to Figures 1-6A PTA slurry mixing tank includes a mixing tank 1 for holding materials. A drive rod 7 is rotatably connected to the inner wall of the mixing tank 1. A connecting block 8 is fixedly connected to the outer wall of the drive rod 7. Connecting rods 11 are rotatably connected to both sides of the connecting block 8. A first gear 5 is fixedly connected to the top of the connecting rod 11. An adjusting gear ring 6 is fixedly connected to the inner wall of the mixing tank 1. The outer wall of the first gear 5 meshes with the inner wall of the adjusting gear ring 6 to rotate the connecting rod 11. The outer walls of the first gear 5 and the adjusting gear ring 6 are coated with anti-corrosion paint. A mounting frame 2 is fixedly connected to the top of the mixing tank 1. Protective covers 3 are rotatably connected to both sides of the top of the mounting frame 2. A servo motor 4 is fixedly connected to the top of the mounting frame 2. The drive end of the servo motor 4 is fixedly connected to the top of the drive rod 7.

[0032] Specifically, the protective cover 3 is opened and the material is poured into the mixing tank 1. The servo motor 4 is started to drive the drive rod 7 to rotate. The drive rod 7 drives the connecting block 8 to rotate around the drive rod 7. When the connecting block 8 rotates, the first gear 5 meshes with the adjusting gear ring 6, driving the first gear 5 to rotate. The rotation of the first gear 5 drives the connecting rod 11 to rotate, causing the stirring rod 10 to rotate. The stirring rod 10 rotates around the drive rod 7 while rotating on its own axis to accelerate the mixing efficiency. At the same time, the outer walls of the first gear 5 and the adjusting gear ring 6 are coated with anti-corrosion paint to prevent material corrosion.

[0033] Example 2:

[0034] refer to Figures 1-6 The bottom of the connecting rod 11 is fixedly connected to the mounting block 12. The inner wall of the mounting block 12 is inserted into the fixing block 13. The inner wall of the mounting block 12 is slidably connected to the limiting plug 15. The outer wall of the limiting plug 15 is inserted into the inner wall of the fixing block 13. The bottom of each of the two limiting plugs 15 is fixedly connected to the limiting rack 20. The two limiting racks 20 are meshed on the side close to each other and connected to the second gear 19. The top of the second gear 19 is fixedly connected to the worm gear 18. The outer wall of the worm gear 18 is meshed with the worm 16. The right end of the worm 16 is fixedly connected to the adjusting knob 17 for fixing the fixing block 13. The bottom of the fixing block 13 is fixedly connected to the stirring rod 10. The inner wall of the mounting block 12 is fixedly connected to the six limiting blocks 14. The outer wall of the limiting blocks 14 is inserted into the top of the fixing block 13. The outer wall of the drive rod 7 is fixedly connected to the scraper 9.

[0035] Specifically, when the stirring rod 10 needs to be disassembled for maintenance, the protective cover 3 is opened. Because the protective cover is large, the disassembled stirring rod 10 can be removed using the unfolded space. The adjustment knob 17 is turned to drive the worm gear 16 to rotate. The rotation of the worm gear 16 meshes with the worm wheel 18, causing the worm wheel 18 to rotate. The rotation of the worm wheel 18 drives the second gear 19 to rotate. The rotation of the second gear 19 meshes with the limiting rack 20, causing the limiting rack 20 to slide. When the limiting rack 20 slides, it drives the limiting insert 15 to slide, releasing the fixing block 13 and allowing the stirring rod 10 to be disassembled for maintenance. At the same time, when the stirring rod 10 rotates, the drive rod 7 drives the scraper 9 to scrape the inner wall of the mixing tank 1 to prevent the material from sticking together.

[0036] Working principle: When starting work, open the protective cover 3 and pour the material into the mixing tank 1. Start the servo motor 4 to make the drive rod 7 rotate. The drive rod 7 drives the connecting block 8 to rotate around the drive rod 7. When the connecting block 8 rotates, the first gear 5 meshes with the adjusting gear ring 6 to drive the first gear 5 to rotate. The rotation of the first gear 5 drives the connecting rod 11 to rotate, which makes the stirring rod 10 rotate to stir the material in the mixing tank 1, thus improving the stirring efficiency.

[0037] When the stirring rod 10 needs to be disassembled for maintenance, turn the adjustment knob 17 to rotate the worm 16. The rotation of the worm 16 meshes with the worm wheel 18, causing the worm wheel 18 to rotate. The rotation of the worm wheel 18 drives the second gear 19 to rotate. The rotation of the second gear 19 meshes with the limiting rack 20, causing the limiting rack 20 to slide. The limiting rack 20 drives the limiting insert 15 to slide, releasing the fixing block 13, and the stirring rod 10 can be disassembled for maintenance.
