[0028] Reference Figures 1 to 4This application provides a spray granulation system, comprising: a stirring device 100 for stirring materials, the stirring device 100 being provided with a first discharge pipe 110; a screening device 200 connected to the first discharge pipe 110 for screening materials, the screening device 200 being provided with a second discharge pipe 210; a storage tank 300 connected to the second discharge pipe 210 for temporarily storing materials, the storage tank 300 being provided with a sensor for detecting the material condition inside the storage tank 300, the storage tank 300 being provided with a third discharge pipe 310, the third discharge pipe 310 being provided with a first discharge pump 320, the first discharge pump 320 being connected to the sensor; and a spray granulation device connected to the third discharge pipe 310, the spray granulation device being provided with a first discharge pipe 410.

[0029] By installing a sensor inside the storage tank 300, when the sensor detects that the material in the storage tank 300 has reached the set liquid level, the first discharge pump 320 is turned on, and the material in the storage tank 300 enters the spray granulation device through the third discharge pipe 310. Then, the material is dried and shaped by the spray granulation device. During this process, the spray granulation device operates intermittently, which can reduce the risk of damage to the spray granulation device caused by long-term continuous operation, extend the service life of the spray granulation device, and reduce production costs.

[0030] Reference Figure 1 and Figure 2 The spray granulation device includes a flash evaporator 420 and a granulator 430. The flash evaporator 420 is connected to a third discharge pipe 310 and has a fourth discharge pipe 421. The granulator 430 is connected to the fourth discharge pipe 421, and a first discharge pipe 410 is located at the granulator 430. The material is flash-dried by the flash evaporator 420 and then granulated by the granulator 430, thereby improving drying efficiency and product quality. The granulator 430 includes a tank 431 and an atomizer 432. The tank 431 has a first inlet 433 connected to the fourth discharge pipe 421. The atomizer 432 is located at the first inlet 433, and the first discharge pipe 410 is located at the bottom of the tank 431. After being flash-dried by the flash evaporator 420, the material enters the tank 431 through the first feed port 433. Under the action of the atomizer 432, the material is atomized and dispersed into small droplets to facilitate granulation and drying of the material, thereby improving work efficiency and product quality.

[0031] Reference Figure 2In some embodiments of this application, the spray granulation device further includes a cyclone separator 440. The tank 431 is provided with a fifth discharge pipe 434, and the cyclone separator 440 is connected to the fifth discharge pipe 434. The cyclone separator 440 is also provided with a second discharge pipe 441. After the material is atomized and dispersed into small droplets by the atomizer 432 and granulated and dried, the large particles accumulate at the bottom of the tank 431 and can be discharged from the first discharge pipe 410. The smaller particles are carried by air out of the fifth discharge pipe 434, separated by the cyclone separator 440, and finally discharged from the second discharge pipe 441. By adopting the above structure, the separated discharge improves the consistency of the product particle size, which is beneficial to improving product quality.

[0032] It is conceivable that the cyclone separator 440 is equipped with an exhaust pipe 442, which is connected to an air processor 443. The air processor 443 is configured as a bag filter. Because the separation efficiency of the cyclone separator 440 is limited, the air discharged from the exhaust pipe 442 will still contain fine particulate matter. Therefore, the air processor 443 filters out these fine particulate materials, thus avoiding resource waste, reducing costs, and promoting environmental friendliness.

[0033] Reference Figure 1 and Figure 3 In this embodiment, the stirring device 100 includes a stirring tank 130 and a stirring mechanism. A first discharge pipe 110 is disposed in the stirring tank 130, and a second discharge pump 120 is provided in the first discharge pipe 110. The stirring mechanism is disposed inside the stirring tank 130 to stir the material. Specifically, the stirring mechanism includes a base 140, a stirring shaft 150, and stirring blades 160. The base 140 is disposed on one side of the stirring tank 130, the stirring shaft 150 is rotatably disposed on the base 140 and extends into the stirring tank 130, and the stirring blades 160 are disposed on the stirring shaft 150. The rotation of the stirring shaft 150 drives the stirring blades 160 to rotate, so that the stirring blades 160 stir the material in the stirring tank 130, making the material uniformly stirred. Then, the uniformly stirred material is led out from the first discharge pipe 110 by the second discharge pump 120 for subsequent granulation of the material, thereby improving work efficiency and ensuring product quality.

[0034] Reference Figure 1 and Figure 4The screening device 200 includes a base 220, a housing 230, and a screen 240. The housing 230 is mounted on the base 220 via an elastic mechanism 250. A second discharge pipe 210 is located at the bottom of the housing 230, and the screen 240 is located inside the housing 230. A second feed inlet 260 is located at the top of the housing 230, and a first discharge pipe 110 is connected to the second feed inlet 260. A vibrator 270 is installed in the housing 230. The housing 230 includes a lower shell 231 and an upper cover 232. The second discharge pipe 210 is located on the lower shell 231, the screen 240 is located on top of the lower shell 231, and the upper cover 232 is located above and connected to the lower shell 231. The second feed inlet 260 is located on the upper cover 232. When the vibrator 270 operates, it causes the lower shell 231 to vibrate the screen 240, thereby achieving vibration screening of materials and improving product quality. It is conceivable that the elastic mechanism 250 is set as a spring, with both ends of the spring connected to the lower shell 231 and the base 220 respectively, which is simple in structure and easy to operate.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
