[0032] Specifically, the servo motor 5 can drive the first rotating rod 6 to rotate clockwise, and the first gear 8 will rotate in a circle at the center of the bottom end of the first rotating rod 6. Since the second hollow gear ring 10 is meshed with the first gear 8, the first gear 8 can be driven to rotate at the bottom end of the curved rod 7 under the action of the second hollow gear ring 10. At the same time, the second gear 13 meshed with the first gear 8 also starts to rotate. This design enables the second rotating rod 11 to rotate counterclockwise under the drive of the servo motor 5, thereby achieving uniform mixing of the polymer solution. Through this careful design, uniform mixing of the polymer solution can be achieved, thereby improving the uniformity and stability of the solution, which is not only beneficial to the processing process of the polymer solution, but also can improve the performance and quality of the product.

[0033] Reference Figure 2 and Figure 3 The cleaning mechanism 2 includes a driving gear 201, which is fixedly connected to the middle and upper part of the outer side of the first rotating rod 6. The right end of the inner top of the kettle cover 4 is rotatably connected with a movable shaft 202. The outer side of the movable shaft 202 is fixedly connected with a driven gear 203. The driven gear 203 is meshed with the driving gear 201. The inner top of the kettle cover 4 is rotatably connected with a first hollow gear ring 204. The first hollow gear ring 204 is meshed with the driven gear 203. A plurality of special-shaped scrapers 205 are fixedly connected around the bottom of the first hollow gear ring 204. The left and right sides of the circular ring 14 are fixedly connected with connecting rods 15. One end of the connecting rod 15 is fixedly connected to one side of the corresponding special-shaped scraper 205. The sizes of the plurality of special-shaped scrapers 205 match the internal size of the kettle body 3.

[0034] Specifically, when the first rotating rod 6 rotates, the driving gear 201 on its outer side also rotates accordingly. As the driving gear 201 rotates, the driven gear 203 also starts to rotate immediately thereafter. At this time, the first hollow gear ring 204 connected to the driven gear 203 also starts to rotate, and the special-shaped scraper 205 will rotate accordingly to scrape off the impurities remaining on the inner wall of the kettle body 3. It is relatively simple for the staff to clean the inner wall of the kettle body 3, thereby improving the practicality of the device.

[0035] Reference Figure 1 The left side of the kettle body 3 is fixedly connected with a controller 20, the controller 20 is electrically connected to the servo motor 5, and a protective cover 21 is arranged on the outside of the controller 20, and one end of the protective cover 21 is rotatably connected to the left side of the kettle body 3;

[0036] Specifically, the operation of the servo motor 5 can be controlled by the controller 20 , and the protective cover 21 can protect the controller 20 from being damaged by external factors.

[0037] Reference Figure 1 and Figure 2 The left and right sides of the kettle cover 4 are both threadedly connected with bolts 23, and one end of the bolt 23 passes through the kettle cover 4 and the kettle body 3 in sequence;

[0038] Specifically, loosening the bolts 23 can release the limiting fixation of the kettle cover 4, and then the kettle cover 4 can be removed to inspect and maintain the structure at its bottom.

[0039] Reference Figure 1 , an observation window 22 is provided in the middle of the front side of the kettle body 3;

[0040] Specifically, the observation window 22 can be used to facilitate the staff to check the internal conditions of the kettle body 3 at any time, and can respond in time when encountering special situations.

[0041] Working principle: When using the device, first pour the polymer solution raw materials to be mixed into the kettle body 3 through the liquid inlet 18 in sequence. At this time, the servo motor 5 can drive the first rotating rod 6 to rotate clockwise, and the first gear 8 will rotate in a circle at the center of the bottom end of the first rotating rod 6. Since the second hollow gear ring 10 is meshed with the first gear 8, the first gear 8 can be driven to rotate at the bottom end of the curved rod 7 under the action of the second hollow gear ring 10. The second gear 13 will also rotate with it due to the meshing with the first gear 8. Since the direction of the second gear 13 is opposite to that of the first gear 8, it can drive the second rotating rod 11 to rotate counterclockwise, so that the polymer solution is mixed more The mixing effect of the polymer solution is improved, and the processing quality of the polymer solution is not affected, which can meet the needs of users. When the first rotating rod 6 rotates, the driving gear 201 on the outside thereof will rotate accordingly, and the driven gear 203 will also rotate due to the engagement with the first rotating rod 6. At this time, the first hollow gear ring 204 will also rotate, thereby driving the special-shaped scraper 205 to rotate to scrape off the impurities remaining on the inner wall of the kettle body 3. It is relatively simple for the staff to clean the inner wall of the kettle body 3, thereby improving the practicability of the device.
