[0003] However, current cooling granulation spray dryers are prone to clogging the spray nozzles when producing different materials with varying properties, such as different particle sizes and viscosities, which affects the spraying effect and reduces particle quality. Furthermore, once completely clogged, the machine needs to be shut down for maintenance, reducing processing efficiency. In addition, different materials require different nozzle diameters, which is difficult to change or requires changing to different nozzles, which is time-consuming and labor-intensive.

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0026] like Figure 1 The cooling granulation spray dryer shown includes a body 1, a cold air nozzle 2 installed on the top of the body 1, and a cold air duct 3 connected to the cold air nozzle 2. Cold air is sent to the cold air nozzle 2 through the cold air duct 3 and then into the body 1 to cool the material. At the bottom of the body 1, a cyclone separator 10 and a material pipe 4 for conveying materials are connected through a discharge pipe 9. A selection plate 6 is provided inside the body 1. The selection plate 6 is connected to the inner wall of the body 1 through a connecting rod 7. A multi-functional material spray head 5 is provided below the selection plate 6. The multi-functional material spray head 5 cooperates with a functional rod 8. The multi-functional material spray head 5 is moved by the functional rod 8 to change the nozzle outlet.

[0027] like Figure 2 The multifunctional material spray head 5 shown includes a connecting pipe 51, a support pipe 52, and a screening disc 53. The end of the support pipe 52 is provided with a bearing 54. The screening disc 53 is connected to the support pipe 52 through the bearing 54. The rotation of the screening disc 53 can be realized through the bearing 54. The bottom of the connecting pipe 51 is connected to the material pipe 4. The material is transported through the material pipe 4 and sprayed out through the connecting pipe 51.

[0028] like Figure 2 , Figures 3 to 4 The screening disc 53 shown includes a sieve plate 531, on which a plurality of screening mesh holes 532 and a connecting port 533 are provided. In some examples, the screening mesh holes 532 are evenly distributed in the sieve plate 531. If the sieve plate 531 is circular, then the sieve plate 531 is provided with a plurality of screening mesh holes 532 at equal angular intervals along the circumference. The mesh diameters of the plurality of screening mesh holes 532 may be the same or different. The outer edge of the sieve plate 531 is connected to gear teeth 534, and the screening disc 53 is connected to... The port 533 is connected to the bearing 54, which allows the screening disc 53 to rotate, thereby enabling the selection of different screening meshes 532. The screening meshes 532 are slidably fitted to the top outlet of the connecting pipe 51. This sliding fit ensures that different screening meshes 532 and the connecting pipe 51 can be sealed and fitted together, while also allowing for the selection of different screening meshes 532. The bottom of the sieve plate 531 is provided with several fixing grooves 535, and the fixing grooves 535 are preferably located between two screening meshes 532.

[0029] like Figure 2 , Figure 3 , Figure 5 The selection plate 6 has a through hole 61 in the middle, which cooperates with the screening mesh 532. In use, the screening mesh 532 connected to the connecting pipe 51 is aligned with the through hole 61. The shape of the through hole 61 is the same as that of the screening mesh 532, and its area is greater than or equal to that of the screening mesh 532. When the areas are the same, the bottom edge of the through hole 61 is close to the top edge of the screening mesh 532. When the area is greater, the bottom edge of the through hole 61 is close to the surface of the sieve plate 531.

[0030] like Figure 2 , Figure 5 , Figure 7The functional lever 8 shown includes a main lever 81 and an adjusting lever 86. One end of the main lever 81 is connected to a handle 83, and the other end is connected to an auxiliary gear 84. The main lever 81 has a moving cavity 82 inside, and the adjusting lever 86 is disposed in the moving cavity 82. One end of the adjusting lever 86 extends outward through the handle 83, with an extension length preferably of 2-3 cm. The other end of the adjusting lever 86 extends outward through the auxiliary gear 84 and is connected to a fixed head 87. The adjusting lever 86 is provided with a first baffle plate 861. The second barrier plate 862, the first barrier plate 861, and the second barrier plate 862 are in the motion cavity 82. A return spring 88 is provided between the first barrier plate 861 and the auxiliary gear 84. After the adjusting rod 86 is pressed inward, the return spring 88 can restore the adjusting rod 86 to its original state. The second barrier plate 862 is close to the handle 83 to prevent the adjusting rod 86 from coming outward. The auxiliary gear 84 meshes with the gear teeth 534 to ensure that the screening disc 53 is driven to rotate when the function rod 8 is rotated.

[0031] like Figure 1 , Figure 5 The main rod 81 shown is equipped with a rolling bearing 85, which is installed in the wall of the machine body 1. Through the action of the rolling bearing 85, the functional rod 8 can rotate more easily.

[0032] like Figure 4 , Figure 5 The fixing groove 535 shown is used in conjunction with the fixing head 87. In use, the fixing head 87 is inserted into the fixing groove 535 to fix the screening disc 53.

[0033] In use, the user presses the adjusting rod 86 inward to disengage the fixing head 87 from the fixing groove 535, rotates the handle 83 to drive the auxiliary gear 84 to rotate, which in turn drives the gear teeth 534 to rotate, thereby rotating the screening disc 53. At the same time, the pressure on the adjusting rod 86 is released. When it is about to rotate to a new screening mesh 532, the fixing head 87 will touch the next fixing groove 535. At this time, the user presses the adjusting rod 86 inward again and rotates the handle slightly to insert the fixing head 87 into the fixing groove 535, thereby changing the new screening mesh 532 and fixing the screening disc 53. After the material enters through the material pipe 4, it is sprayed out from the screening mesh 532 through the connecting pipe 51 and dried and granulated by cold air.

[0034] The detailed descriptions listed above are merely specific descriptions of feasible implementations of this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
