[0024] Figure 1 The diagram shows a schematic of the cyclone spray granulation dryer disclosed in the embodiment of the present invention. The cyclone spray granulation dryer includes a heating zone 1, a granulation zone 2, a drying zone 13 and a dust removal zone 3 arranged sequentially from bottom to top. Both the granulation zone 2 and the drying zone 13 are equipped with spray guns 6 and air hammers 5. The spray guns 6 are used for feeding materials, and the air hammers 5 are used for introducing compressed air into the granulation zone 2 and the drying zone 13.

[0025] Dust removal zone 3 is equipped with dust collector bags 4 and a pulse controller 10. The control system includes a control unit 12, a temperature sensor 7, a wind speed sensor 8, a flow sensor 14, a pressure sensor 9, and a nozzle outlet monitoring device 11. The control unit 12 is electrically connected to the temperature sensor 7, the wind speed sensor 8, the flow sensor 14, the pressure sensor 9, the nozzle outlet monitoring device 11, the spray gun 6, the air hammer 5, and the pulse controller 10. Heating zone 1, granulation zone 2, drying zone 13, and dust removal zone 3 are each equipped with at least one temperature sensor 7. A pressure sensor 9 is installed at the bottom and top of the dust collector bags 4 in dust removal zone 3. A wind speed sensor 8 is installed in dust removal zone 3. Figure 2 A system block diagram of the control system is shown.

[0026] In a preferred embodiment, the spray gun 6 is disposed in the granulation zone 2 and / or the drying zone 13. The spray gun 6 disposed in the drying zone 13 feeds downwards, while the spray gun 6 disposed in the granulation zone 2 feeds upwards, ensuring that the material is evenly distributed in the granulation zone 2 and the drying zone 13, thereby improving granulation uniformity and efficiency and adapting to different production process requirements.

[0027] In a preferred embodiment, the cyclone spray granulation dryer further includes an online cleaning device 15, which extends downward from the top of the dust removal zone 3. The lower end of the online cleaning device 15 has a spraying mechanism. The online cleaning device 15 can perform 360° cleaning on the drying zone 13 and the granulation zone 2. The online cleaning device 15 is electrically connected to the control system 12, which can control the opening and closing of the online cleaning device 15.

[0028] During operation, heating zone 1 heats the incoming air, and then the hot air enters granulation zone 2 and drying zone 13. Control unit 12 controls the feeding speed of spray gun 6 through feedback data from flow sensor 14. Control unit 12 can also control the speed at which compressed air is introduced into air hammer 5 through feedback data from flow sensor 14. The material is granulated and dried in granulation zone 2 and drying zone 13. Afterward, the hot air is discharged after passing through dust collector bag 4.

[0029] During this process, the control unit 12 receives temperature parameters in real time from temperature sensors 7 located in the heating zone 1, granulation zone 2, drying zone 13, and dust removal zone 3, and adjusts the temperature of the heating zone 2 when necessary. The control unit 12 determines whether the dust removal bag 4 is full based on the pressure difference between pressure sensors 9 located at the top and bottom of the dust removal bag 4, and simultaneously determines whether dust removal is needed based on wind speed changes detected by the wind speed sensor 8 located in the dust removal zone 3. When dust removal is required, the control unit 12 controls the pulse dust collector to remove dust from the dust removal zone 3. By using pressure sensors 9 located at the top and bottom of the dust removal bag 4, combined with wind speed sensor 8 to monitor wind speed changes, the saturation status of the dust removal bag 4 can be determined, improving accuracy.

[0030] The nozzle outlet is equipped with a nozzle outlet monitoring device 11. The device displays the information on the nozzle outlet to determine whether the nozzle outlet is discharging material normally. It can monitor the status of the outlet in real time, promptly detect and handle any abnormal discharge situations, and ensure the continuity of the production process and the stability of the discharge quality.

[0031] This invention uses a control unit 12 to collect data from temperature sensor 7, wind speed sensor 8, flow sensor 14, and pressure sensor 9. This enables real-time monitoring of the heating zone 1, granulation zone 2, drying zone 13, and dust removal zone 3. Based on real-time data, it can adjust the temperature of, for example, the heating zone 1, ensuring the stability of temperature, wind speed, and pressure during granulation and drying processes, thereby improving product quality and production efficiency. By monitoring key parameters through multiple sensors and providing real-time feedback to the control unit 12, precise control of each zone is achieved, improving drying efficiency and material handling accuracy, while reducing energy consumption and production costs.
