Detailed implementation manners

[0024] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a 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 those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment:

[0026] Please refer to Figures 1 - 5 , the present invention provides a technical solution:

[0027] A fluidized bed granulation and coating machine includes a main body 1 of the chassis. A connecting cylinder 2 is arranged on the outer side of the main body 1 of the chassis. A plurality of groups of filtering components 3 are arranged on the top of the connecting cylinder 2. And a connecting cover 4 is arranged at one end of the connecting cylinder 2 close to the filtering component 3. The plurality of groups of filtering components 3 are connected to each other. A guiding component 5 is arranged inside the connecting cylinder 2. And a connecting plate 6 is arranged at one end of the connecting cylinder 2 close to the main body 1 of the chassis. A plurality of air outlets 7 are formed inside the connecting plate 6. A spray pipe 8 is arranged on the outer side of the main body 1 of the chassis and close to one end of the connecting cylinder 2. One end of the spray pipe 8 far away from the main body 1 of the chassis extends into the connecting cylinder 2;

[0028] The filtering component 3 is used for filtering the gas discharged from the connecting cylinder 2;

[0029] Furthermore, the filtering component 3 is composed of a connecting ring 9, a moving block 10, a fixing rod 11, a sliding rod 12, a fixing groove 13 and a fixing block 14. The connecting ring 9 is located on the top of the connecting cylinder 2 and inside the connecting cover 4. Two moving blocks 10 are both slidably connected inside the connecting ring 9. Two fixing rods 11 are both located on the outer sides of the moving blocks 10. The sliding rod 12 is located inside the connecting ring 9 and inside the moving blocks 10. Two fixing grooves 13 are both formed inside the connecting ring 9 and are respectively close to both ends of the two moving blocks 10. Two fixing blocks 14 are both located at the bottom of the connecting ring 9. When the gas inside the connecting cylinder 2 is discharged, the filtering component 3 can filter it, so that the dust and odor carried in the gas can be filtered to prevent direct discharge and affect the working environment.

[0030] Among them, the moving block 10 is slidably connected to the sliding rod 12. A compression spring 15 is provided outside the sliding rod 12 and on the outside of the moving block 10. The compression spring 15 is connected to the moving block 10 through the sliding rod 12. The moving block 10 is slidably connected to the sliding rod 12, so that the moving block 10 can be connected to the compression spring 15 outside the sliding rod 12. The compression spring 15 can drive the moving block 10 to displace, so that the fixed rod 11 can displace.

[0031] Secondly, the external structure size of the fixed block 14 corresponds to the internal structure size of the fixed groove 13. The fixed rod 11 is slidably connected to the fixed groove 13. Two sets of clamping grooves 16 are opened inside the fixed block 14. The internal structure size of the clamping grooves 16 corresponds to the external structure size of the fixed rod 11. The fixed block 14 is connected to the fixed rod 11 through the clamping grooves 16. The two connecting rings 9 are connected to each other, so that the two fixed blocks 14 can be displaced into the fixed groove 13. The compression spring 15 drives the moving block 10 to displace, so that the fixed rod 11 can displace. It is displaced into the fixed groove 13 and contacts the fixed block 14, and is clamped inside the clamping groove 16, so as to be limitedly connected to the fixed block 14, so that the fixed block 14 can be limited inside the fixed groove 13. Therefore, the two connecting rings 9 can be limitedly connected to each other to complete the assembly.

[0032] Furthermore, a catalytic activated carbon filter screen 17, a HEPA filter screen 18, and a gelatinized cotton coarse filter screen 19 are respectively provided inside the multiple connecting rings 9. When gas is introduced into the multiple connecting rings 9, it is sequentially filtered through the gelatinized cotton coarse filter screen 19, the HEPA filter screen 18, and the catalytic activated carbon filter screen 17, and the dust and odor in the gas can be filtered out, ensuring the cleanliness of the gas discharged to the outside and preventing the working environment from being affected.

[0033] The diversion assembly 5 is used for diverting the particles inside the connecting cylinder 2;

[0034] Furthermore, the diversion assembly 5 is composed of a rotating disk 20, a diversion block 21, a through groove 22, a bevel gear ring 23, and a bevel gear 24. The rotating disk 20 is rotatably connected to the inside of the connecting cylinder 2. The diversion block 21 is located on the top of the rotating disk 20. Multiple through grooves 22 are respectively opened inside the rotating disk 20 and the diversion block 21. The bevel gear ring 23 is fixedly connected to one end of the rotating disk 20 away from the diversion block 21. The bevel gear 24 is meshed and connected to the outside of the bevel gear ring 23. When the particles are coated inside the connecting cylinder 2, the diversion assembly 5 can divert them, and the particles can be coated more evenly.

[0035] Furthermore, the rotating disk 20 is designed in a concave structure. Multiple groups of through grooves 22 are evenly distributed at equal intervals inside both the rotating disk 20 and the diversion block 21. One end of the bevel gear 24 away from the bevel gear ring 23 is fixedly connected to the driving end of the driving motor. When the driving motor is started, the bevel gear 24 is driven to rotate, enabling the bevel gear ring 23 to rotate, driving the rotating disk 20 to rotate. When the rotating disk 20 rotates, the diversion block 21 inside it can rotate. The particles on the rotating disk 20 and the coating liquid sprayed from the nozzle 8 jointly flip around the diversion block 21, simulating the rotation of planets around a star in a galaxy, and coating the material more evenly.

[0036] In this embodiment, the implementation scenario is as follows: In actual use, the two connecting rings 9 are connected to each other, enabling the two fixing blocks 14 to be displaced into the fixing slots 13. The compression spring 15 drives the moving block 10 to be displaced, enabling the fixing rod 11 to be displaced and moved into the fixing slots 13, coming into contact with the fixing blocks 14 and being clamped inside the clamping slots 16, thereby making a limit connection with the fixing blocks 14, enabling the fixing blocks 14 to be limited inside the fixing slots 13. Therefore, the two connecting rings 9 can be mutually limited and connected to complete the assembly. When gas is introduced into the multiple connecting rings 9, it is filtered successively through the gelatinized cotton coarse filter screen 19, the HEPA filter screen 18, and the catalytic activated carbon filter screen 17, capable of filtering out dust, odors, etc. in the gas, ensuring the cleanliness of the gas discharged to the outside and preventing the working environment from being affected. When the driving motor is started, the bevel gear 24 is driven to rotate, enabling the bevel gear ring 23 to rotate, driving the rotating disk 20 to rotate. When the rotating disk 20 rotates, the diversion block 21 inside it can rotate. The particles on the rotating disk 20 and the coating liquid sprayed from the nozzle 8 jointly flip around the diversion block 21, simulating the rotation of planets around a star in a galaxy, and coating the material more evenly. Compared with the existing coating machines, the overall practicality of the coating machine can be improved through the design of the present utility model.

[0037] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
