The material barrel is often made of stainless steel or plated on stainless steel. The dual planetary mixing paddles play a role in mixing and stirring the materials in the material barrel, while the dispersing paddles play a role in dispersing the solvent added to the materials in the later stage of pulping. However, during the pulping process, part of the pulp will always adhere to the barrel, which is not conducive to sufficient stirring during the stirring process, nor is it conducive to the subsequent cleaning of the material barrel.

[0011] Furthermore, the scraper paddle also includes:

[0012] A through hole is arranged on the scraper.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0030] Embodiment 1:

[0031] This embodiment provides an automatic scraping stirring device, comprising:

[0032] Bracket 1;

[0033] Planet box 3, planet box 3 is installed on bracket 1;

[0034] A material making barrel 2, which is installed below the planetary box 3;

[0035] A stirring paddle 4, which is mounted on the output end of the planetary box 3 and driven to rotate by the planetary box 3;

[0036] The scraper paddle 5 includes a rotating shaft 51 and a scraper 52 . The rotating shaft 51 is mounted on the output end of the planetary box 3 and is driven to rotate by the planetary box 3 . The scraper 52 is mounted on the rotating shaft 51 and abuts against the inner wall of the material making barrel 2 .

[0037] In this technical solution, the planetary box 3 is installed in the bracket 1, and the stirring paddle 4 is installed on the driving end of the planetary box 3. When the pulping operation is performed, the planetary box 3 controls the stirring paddle 4 and the scraping paddle 5 to revolve around the center of the planetary box 3, and the scraping paddle 5 and the scraping paddle 5 itself will rotate. Figure 3 , 4 As shown, the revolution principle of the stirring paddle 4 and the scraper paddle 5 is as follows: by setting a transmission gear 71 and a chain 72, the output end of the first motor 7 and the main shaft 73 inside the planetary box 3 are connected and matched with each other by transmission, the first motor 7 is started to drive the main shaft 73 to rotate, the main shaft 73 is connected to the fixed disk 76, and the rotation of the main shaft 73 drives the fixed disk 76 to rotate, so that the stirring paddle 4 and the scraper paddle 5 installed on the fixed disk 76 rotate around the center of the disk body as the fixed disk 76 rotates, thereby realizing the revolution motion of the stirring paddle 4 and the scraper paddle 5.

[0038] The self-rotation principle of the stirring paddle 4: a first driving gear 74 is provided on the main shaft 73, and the rotation of the main shaft 73 drives the first driving gear 74 to rotate, and the first driving gear 74 drives the first driven gear 75 meshing therewith to rotate, so that the stirring paddle 4 fixedly connected to the first driven gear 75 rotates with the rotation of the first driven gear 75, thereby realizing the self-rotation movement of the stirring paddle 4.

[0039] The principle of the self-rotation of the scraper paddle 5 is as follows: by setting a pulley 81 and a transmission belt 82, the output end of the second motor 8 and the central shaft 83 inside the main shaft 73 are connected and matched with each other in a transmission manner. The central shaft 83 is arranged in the main shaft 73 and is rotatably connected to the main shaft 73. A second driving gear 84 is arranged on the central shaft 83. The second motor 8 is started to control the rotation of the driving central shaft 83, which drives the second driving gear 84 to rotate. The second driving gear 84 drives the second driven gear 85 meshing with it to rotate, so that the scraper paddle 5 fixedly connected to the second driven gear 85 rotates as the second driven gear 85 rotates, thereby realizing the self-rotation of the scraper paddle 5.

[0040] The stirring paddle 4 performs revolution and rotation to stir and mix the materials in the material barrel 2. During the material stirring and mixing process, some materials are likely to adhere to the inner wall of the material barrel 2, or splash to the higher part of the inner wall of the material barrel 2. The scraper paddle 5 performs revolution along the inner wall of the material barrel 2 to scrape off the materials adhered to various positions of the inner wall of the material barrel 2, and pulls the scraped materials from the barrel wall to the center position, so that they are more in contact with the stirring paddle 4, speeding up the stirring and mixing of the materials, and effectively preventing insufficient stirring. The self-rotation of the scraper paddle 5 can further mix and push the materials, strengthen the stirring and mixing effect of the materials, thereby ensuring that all materials are evenly mixed, and further improving the mixing efficiency. In addition, after the solvent is added in the later stage of pulping, the scraper paddle 5 can also disperse the solvent added to the materials.

[0041] After the slurry is stirred, the prepared slurry is discharged from the material preparation barrel 2 for storage, and a certain amount of slurry will still adhere to the inner wall of the material preparation barrel 2. The slurry adhered to the inner wall of the material preparation barrel 2 can also be scraped off by the stirring device, thereby reducing the workload of subsequent cleaning and maintenance of the material preparation barrel 2.

[0042] In summary, when the stirring device is stirring and mixing materials, the scraper paddle 5 can scrape the materials adhering to the inner wall of the material barrel 2 and push them to the central area of ​​the material barrel 2, thereby enhancing the stirring and mixing effect, making the various materials in the slurry more fully mixed and improving the stirring efficiency; in the later stage of slurry preparation, the scraper paddle 5 can also play a dispersing role, improve the dispersing efficiency, reduce the slurry preparation time, and improve the production efficiency. After the slurry preparation is completed, the inner wall of the material barrel 2 can also be cleaned to facilitate subsequent cleaning.

[0048] In the present technical solution, a plurality of through holes 53 are provided in the scraper 52 so that the slurry can flow through the through holes 53 of the scraper 52 when the scraper 52 revolves and rotates, thereby changing the turbulent characteristics of the slurry, enhancing the dispersing effect of the scraper 52, and promoting more effective mixing of various materials in the slurry, making the stirring and mixing of the slurry more uniform and sufficient, and effectively improving the stirring efficiency.
