[0023] Example 1

[0024] See attached document Figs. 1-6This application provides a wet mixing granulator, including a frame 1, on which a granulation pot 2 is mounted to provide granulation space. A stirring shaft 3 is rotatably connected inside the granulation pot 2, and a stirring paddle 4 is fixedly connected to the stirring shaft 3 for stirring the material. A cutting transmission housing 5 is located on one side of the granulation pot 2, and a cutting transmission shaft 6 is connected to the cutting transmission housing 5. The cutting transmission shaft 6 is equipped with cutting blades 7, which cut and disperse the material to achieve a thorough mixing effect. A discharge port 8 is located on the other side of the granulation pot 2 for screening out the material particles. The granulation pot 2 is equipped with a lid 9, which is detachably connected to the granulation pot 2. The lid 9 has a slurry inlet 10 and a feed inlet 11. The slurry inlet 10 is used to add adhesive, and the feed inlet 11 is used to add material (i.e., medicinal powder). The granulation pot 2 is equipped with a scraping assembly 12, which is used to scrape off the material adhering to the pot wall. The scraping assembly 12 includes a scraping shaft 13 and a scraper 14. The scraper 14 is fixed to the scraping shaft 13, and the scraping shaft 13 is coaxially rotatably connected to the stirring shaft 3. A slurry feeder 15 is installed on the frame 1, and the slurry feeder 15 is pipe-connected to the slurry inlet. A material box 16 is installed inside the frame 1, and the material box 16 is connected to the feed inlet 11 via a pump. The material box 16 is placed inside the frame 1, saving space and facilitating operation. During operation, the material is pumped into the granulation pot 2 from the feed inlet 11. The slurry feeder 15 is controlled to spray the binder from the slurry inlet 10. The stirring paddle 4 is started to stir, and the material rotates up and down in the granulation pot 2. At the same time, the material is also centrifuged by the stirring paddle 4. The force acts on the centrifugal motion within the granulation pot 2, creating a semi-fluid mixed state. The material is collided with the cutting blade 7 mounted on the cutting transmission housing 5, where it is cut and dispersed by the cutting blade 7 to achieve thorough mixing. During granulation, the injection of the binder gradually moistens the powder, changing its properties and intensifying the squeezing, friction, and kneading of the material by the stirring paddle 4 and the inner wall of the granulation pot 2, thus completing the granulation process. Simultaneously, the rotation of the scraper shaft 13 drives the scraper 14 to move in a circular motion along the pot wall, scraping off the material adhering to the pot wall, thereby improving efficiency.

[0025] Specifically, a motor 17 is provided at the bottom of the frame 1. The motor 17 is mounted at the bottom of the frame 1. A first gear 18 is provided at the output end of the motor 17. The first gear 18 is mounted on the motor 17. The rotation of the motor 17 drives the first gear 18 to rotate. A second gear 19 is fixedly connected to the stirring shaft 3 and meshes with the first gear 18. The rotation of the first gear 18 drives the rotation of the second gear 19, thereby realizing the rotation and stirring of the stirring shaft 3. A third gear 20 is provided at the bottom of the frame 1 and meshes with the second gear 19. The second gear 19 is rotatably connected to the bottom of the frame 1. The rotation of the second gear 19 drives the rotation of the third gear 20. The fourth gear 21 is fixedly connected below the third gear 20. The fourth gear 21 rotates as the third gear 20 rotates. The scraper shaft 13 is fixedly connected to the fifth gear 22, which meshes with the fourth gear 21. The rotation of the fourth gear 21 drives the rotation of the fifth gear 22, thereby driving the scraper shaft 13 to rotate. The structure is reasonable. The stirring shaft 3 and the scraper shaft 13 are driven to rotate by a single motor 17, which saves energy, reduces costs, and has a compact structure.

[0026] Example 2

[0027] See attached document Figs. 1-6 The difference between this embodiment and Embodiment 1 is that the scraping assembly 12 further includes a blade holder 23, which is fixedly connected to the scraping shaft 13.

The scraping shaft 13 has a first air passage 24 penetrating through the bottom, and the blade holder 23 has a second air passage 25 communicating with the first air passage 24. The blade holder 23 has several air holes 26 communicating with the second air passage 25 on the side facing the scraper 14. An air pipe connector 30 is connected to the bottom of the scraping shaft 13. An air pump 32 is provided inside the frame 1. The air pipe connector 30 is connected to an electric motor via a pipe. The solenoid valve 31 is connected to the air pump 32 via a pipe. The air pipe connector 30 is a rotatable air pipe connector 30, and the air pipe is inserted into the air pipe connector 30. The scraper shaft 13 rotates while the air pipe does not rotate. The frame 1 is provided with a fixing frame 33, and the solenoid valve 31 is installed on the fixing frame 33. The fixing frame 33 is provided with a fixing block 34 for fixing the air pipe. During operation, the air pump 32 pumps high-pressure gas into the air passage through the solenoid valve 31. The gas is sprayed out from the air hole 26 to blow away the material adhering to the scraper 14, thereby cleaning the scraper 14 and ensuring the cleaning efficiency of the scraper 14 on the pot wall.

[0028] Specifically, the frame 1 is equipped with feet 27 for easy installation and transportation.

[0029] Specifically, the frame 1 is provided with a switch door 28, and the switch door 28 is provided with a handle 29, which facilitates the loading and unloading of the material box 16 and the entry into the frame 1 for maintenance. The structure is simple.
