This technology is a granulation technology that completes the powder mixing, granulation and drying steps in a closed container at one time. It is an important equipment in the production of the pharmaceutical industry.

[0003] The air distribution plate structure of the fluidized bed of the existing cyclone granulation coating machine is not strong enough and is easily damaged or deformed under strong air supply, affecting the coating quality; in addition, the existing fluidized bed structure causes channel flow and dead corners in the material, resulting in a low granulation qualification rate. Therefore, it is particularly important to improve the existing fluidized bed structure and design a new fluidized bed structure for the granulation coating machine to solve the above technical defects and improve the practicality of the overall fluidized bed structure.

[0025] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Example:

[0027] See also Figures 1-6 , the utility model provides a technical solution:

[0028] A fluidized bed structure for a granulating coating machine includes a fluidized bed body 1, a plurality of reinforcing ribs 2 are provided on the outside of the fluidized bed body 1, a guide assembly 3 is provided inside the fluidized bed body 1, and a connecting shell 4 is provided outside the guide assembly 3 and inside the fluidized bed body 1;

[0029] The guide assembly 3 is used to guide the material introduced into the fluidized bed body 1, and the guide assembly 3 is composed of a connecting disk 5, a guide block 6 and air holes 7. The connecting disk 5 is rotatably connected to the inside of the fluidized bed body 1, the guide block 6 is located on the top of the connecting disk 5, and multiple groups of air holes 7 are all opened inside the connecting disk 5.

[0030] Furthermore, the connecting plate 5 is designed with a concave structure, the guide block 6 is designed with a conical structure, and multiple groups of air holes 7 are distributed at equal intervals inside the connecting plate 5. Multiple groups of arc blocks 8 are provided inside the fluidized bed body 1 and on the outside of the connecting plate 5. A through groove is provided inside the guide block 6. The connecting plate 5 is designed with a concave structure. When the material is introduced into the interior of the fluidized bed body 1, the material can be contained inside through the connecting plate 5. With the multiple groups of air holes 7, the gas can contact the material. When the connecting plate 5 is in operation, the material can be introduced into the interior of the connecting plate 5 through the multiple groups of arc blocks 8.

[0031] Among them, the bottom of the connecting disk 5 is fixedly connected to a fixing rod, and the end of the fixing rod away from the connecting disk 5 is fixedly connected to the first bevel gear 9, the outer side of the first bevel gear 9 is meshed with the second bevel gear 10, and the interior of the second bevel gear 10 is fixedly connected to the driving end of the driving motor. Starting the driving motor drives the second bevel gear 10 to rotate, so that the first bevel gear 9 rotates, and drives the fixing rod to rotate, thereby causing the connecting disk 5 to rotate. When the connecting disk 5 rotates, it can drive the guide block 6 to rotate for diversion treatment. The coating liquid sprayed from the particles on the connecting disk 5 flips around the guide block 6 together, simulating the rotation of planets around stars in the galaxy, coating the material more evenly, and coating the particles more evenly.

[0032] Secondly, multiple groups of reinforcing ribs 2 are distributed at equal intervals on the outside of the fluidized bed body 1, and a triangular structure is designed between the reinforcing ribs 2 and the fluidized bed body 1. When the fluidized bed body 1 is in use, the strength of the fluidized bed body 1 can be strengthened by multiple groups of reinforcing ribs 2, thereby solving the problem of damage or deformation caused by strong air supply affecting the coating quality.

[0033] Furthermore, a connecting cylinder 11 is provided inside the connecting shell 4, and a conveying auger 12 is rotatably connected inside the connecting cylinder 11. The outside of the conveying auger 12 is fixedly connected to the driving end of the servo motor. The external structure and size of the conveying auger 12 are designed to correspond to the internal structure and size of the connecting cylinder 11, and a plurality of groups of empty slots 13 are provided inside the conveying auger 12. A connecting net 14 is provided on the outside of the connecting shell 4. When the coating liquid is introduced into the interior of the fluidized bed body 1, the coating liquid can be introduced into the interior of the connecting shell 4 through the connecting net 14 and contact the conveying auger 12 inside the connecting cylinder 11. In this way, it can come into contact with the material on the outside of the conveying auger 12, and the connecting shell 4 wraps the guide block 6 inside, starts the servo motor, and drives the conveying auger 12 to rotate. The conveying auger 12 cooperates with the connecting cylinder 11 to introduce the material inside the connecting disk 5 into the interior of the connecting cylinder 11, displace it to the top of the connecting cylinder 11, and then introduce it into the interior of the connecting shell 4, and then re-introduce it into the interior of the connecting disk 5 for circulated coating. When the material comes into contact with the conveying auger 12, the excess coating liquid on the surface of the material can drip into the interior of the connecting disk 5 for utilization through multiple groups of empty slots 13.

[0034] In this embodiment, the implementation scenario is specifically as follows: in actual use, the driving motor is started to drive the second bevel gear 10 to rotate, so that the first bevel gear 9 is rotated, and the fixed rod is driven to rotate, thereby rotating the connecting disk 5. When the connecting disk 5 rotates, it can drive the guide block 6 to rotate to perform diversion processing. The coating liquid sprayed from the particles on the connecting disk 5 flips around the guide block 6 together, simulating the rotation of planets around stars in the galaxy, coating the materials more evenly, and coating the particles more evenly. The servo is started. The motor drives the conveying auger 12 to rotate. The conveying auger 12 cooperates with the connecting tube 11 to introduce the material inside the connecting disk 5 into the interior of the connecting tube 11, displace it to the top of the connecting tube 11, and then introduce it into the interior of the connecting shell 4, and then re-introduce it into the interior of the connecting disk 5 for circulated coating. When the material contacts the conveying auger 12, the excess coating liquid on the surface of the material can drip into the interior of the connecting disk 5 for utilization through multiple groups of empty slots 13. Compared with the existing fluidized bed structure, the utility model can improve the overall practicality of the fluidized bed structure through design.
