All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0034] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , an embodiment provided by the present utility model: a stirring device for a heating tank, including a tank body 1. The tank body 1 is a heating tank and is made of stainless steel material as a whole, specifically No. 304 stainless steel, with strong corrosion resistance. A feed pipe 2 is fixedly connected to the left side of the tank body 1, and a discharge pipe 3 is fixedly connected to the middle side of the bottom of the tank body 1. The feed pipe 2 is used to convey raw materials into the tank body 1, and the discharge pipe 3 is used to facilitate the discharge of the mixed raw materials. A support seat 4 is fixedly connected to the bottom of the tank body 1, and the support seat 4 is used to support the tank body 1. The discharge pipe 3 penetrates through the middle of the support seat 4. A stirring assembly 23 is arranged inside the tank body 1 for mixing raw materials, and a cleaning assembly 24 for cleaning the inner wall of the tank body 1 is arranged inside the stirring assembly 23;

[0035] The stirring assembly 23 includes a motor 5. The motor 5 is fixedly connected to the middle side of the top of the tank body 1. The motor 5 is used to provide driving force. The motor 5 is a Y-series three-phase asynchronous motor, and the specific model is Y80M1-2. A first cylindrical gear 6 is fixedly connected to the bottom of the motor 5. A plurality of uniformly distributed second cylindrical gears 7 are rotatably connected inside the tank body 1. A toothed ring 8 is fixedly connected to the inner wall of the tank body 1. The first cylindrical gear 6, the second cylindrical gears 7, and the toothed ring 8 are all made of cast iron, specifically Q235 ductile iron. A support plate 9 is fixedly connected to the bottom of the first cylindrical gear 6. A support ring 26 is fixedly connected to the bottom of the toothed ring 8. The bottoms of the second cylindrical gears 7 are respectively slidably connected to the tops of the support plate 9 and the support ring 26. The support plate 9 and the support ring 26 are used to provide support force for the second cylindrical gears 7. The second cylindrical gears 7 are all meshed with the first cylindrical gear 6 and the toothed ring 8. A vertical rod 10 is fixedly connected to the bottom of each of the plurality of second cylindrical gears 7. A sleeve rod 11 is fixedly connected to the outer periphery of the vertical rod 10. Stirring blades 15 are fixedly connected to both the front and rear sides of the sleeve rod 11. The vertical rod 10 is used to connect with the second cylindrical gear 7. When the second cylindrical gear 7 rotates, it can drive the vertical rod 10 to rotate, and when the vertical rod 10 rotates, it will drive the stirring blades 15 to rotate together, so that the raw materials can be horizontally rotated and mixed. A housing 17 is installed at the bottom of the vertical rod 10. A first bevel gear 18 is fixedly connected to the bottom of the vertical rod 10. A second bevel gear 19 is rotatably connected to the left side of the housing 17. The first bevel gear 18 is meshed with the second bevel gear 19. The first bevel gear 18 is connected to the vertical rod 10. When the vertical rod 10 rotates, it can control the rotation of the first bevel gear 18, and thus the first bevel gear 18 can control the rotation of the second bevel gear 19. A cross bar 20 is fixedly connected to the middle of the second bevel gear 19. The cross bar 20 is rotatably connected inside the housing 17. Rotating shafts 21 are fixedly connected to both the left and right ends of the cross bar 20. A plurality of uniformly distributed mixing fan blades 22 are fixedly connected to the outer peripheries of the two rotating shafts 21. The cross bar 20 is connected to the rotating shafts 21. When the cross bar 20 rotates, it will control the rotation of the rotating shafts 21, thereby driving the mixing fan blades 22 to rotate, so that the raw materials can be vertically turned and mixed.

[0036] Refer to Figure 1 - Figure 3, the cleaning component 24 includes a plurality of connecting rods 16. The plurality of connecting rods 16 are respectively fixedly connected to the left and right sides of the sleeve rod 11. Opposite ends of the plurality of connecting rods 16 are fixedly connected with stirring fans 12. The connecting rods 16 are used to connect the sleeve rod 11 and the stirring fans 12. When the sleeve rod 11 rotates, the stirring fans 12 can be driven to rotate through the connecting rods 16. Inside both of the two stirring fans 12, there is a sliding connection with a scraping plate 14. On the side of the scraping plate 14 close to the stirring fan 12, there are fixedly connected a plurality of uniformly distributed springs 13. One ends of the plurality of springs 13 far from the scraping plate 14 are all fixedly connected inside the stirring fan 12. The scraping plate 14 is used to clean the inner wall of the tank body 1, and the springs 13 are used to provide elastic support. The springs 13 are made of spring steel, specifically 65Mn spring steel. Inside the stirring fan 12, there is a limit groove 25. One end of the scraping plate 14 close to the stirring fan 12 is slidably connected inside the limit groove 25. The limit groove 25 is used to accommodate the movement of the scraping plate 14.

[0037] Working principle: During operation, the raw materials are conveyed into the tank body 1 through the feed pipe 2. Subsequently, the motor 5 is started, and the rotation of the first cylindrical gear 6 is controlled through the motor 5. When the first cylindrical gear 6 rotates, it will control the corresponding rotation of a plurality of second cylindrical gears 7. The second cylindrical gears 7 are all engaged with the first cylindrical gear 6 and the toothed ring 8. As a result, while the second cylindrical gears 7 rotate around the first cylindrical gear 6, they will also rotate correspondingly by themselves. The vertical rods 10 at the bottoms of the second cylindrical gears 7 will drive the vertical rods 10 to rotate during the rotation of the second cylindrical gears 7. The scraping plates 14 and the stirring blades 15 connected to the outer periphery of the vertical rods 10 will rotate together. The stirring blades 15 will control the horizontal rotation of the raw materials, and the scraping plates 14 will move circumferentially along the inner wall of the tank body 1, thereby cleaning and scraping off the attached raw materials. The acting force generated when the scraping plates 14 come into contact with the raw materials will be applied to the springs 13. As a result, the springs 13 contract and generate a reaction force to push the scraping plates 14, making the scraping plates 14 always fit the inner wall of the tank body 1, and thus gradually scraping off the raw materials;

[0038] While the vertical rod 10 drives the sleeve rod 11 to rotate, it will also drive the first bevel gear 18 and the housing 17 at the bottom to rotate together. When the first bevel gear 18 rotates, it will control the rotation of the second bevel gear 19, and further drive the cross bar 20 to rotate inside the housing 17. As a result, the rotating shafts 21 at both ends of the cross bar 20 will respectively drive a plurality of mixing fan blades 22 to rotate, enabling the raw materials inside the tank body 1 to rotate vertically, and thus achieving the purpose of uniform mixing.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
