Therefore, it is necessary to design a fertilizer production drying device to address the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a fertilizer production drying device, including a drying tank 1, a feeding hopper 2, a transfer pipe 3, a feed pipe 4, a top exhaust pipe 5, a servo motor 6, a central shaft 7, a dispersing fan blade 8, an auger blade 9, an external heating pipe 10, a side exhaust pipe 11, a triangular connecting strip 12, a dispersing cone 13, an internal heating pipe 14, an air inlet pipe 15, and a nozzle 16. The feeding hopper 2 is fixed to the top of the drying tank 1, and the transfer pipe 3 is installed at the bottom of the feeding hopper 2. The bottom of the transfer pipe 3 is connected and fixed to the center of the top surface of the drying tank 1. The top of the feeding hopper 2 has two sides... The feed pipe 4 and the top exhaust pipe 5 are fixed respectively. A servo motor 6 is installed at the center of the top surface of the feed hopper 2. A central shaft 7 is installed at the bottom output end of the servo motor 6. A dispersing fan blade 8 is fixed on the upper part of the central shaft 7. Screw blades 9 are set in the middle and lower part of the central shaft 7. An external heating pipe 10 is installed on the bottom outer wall of the feed hopper 2. A side exhaust pipe 11 is installed on the top of the side wall of the drying tank 1. A triangular connecting strip 12 is installed on the top of the inner wall of the drying tank 1. The end of the triangular connecting strip 12 is connected and fixed to the bottom edge of the dispersing cone 13. An internal heating pipe 14 is installed on the inner wall of the dispersing cone 13.

[0024] In this example, the bottom of the central shaft 7 is lower than the bottom of the transfer tube 3. The length of the part of the central shaft 7 with the auger blades 9 is greater than half the overall length of the central shaft 7. The above structural design allows the fertilizer to be smoothly transported downward when the central shaft 7 rotates with the auger blades 9, avoiding blockage of the transfer tube 3.

[0025] The external heating tubes 10 are evenly spaced and arranged in a ring. The above structural design enables efficient heating and drying of the fertilizer in the feeding hopper 2.

[0026] The triangular connecting strips 12 are distributed at equal angles to the center of the dispersing cone 13. The top of the dispersing cone 13 and the center of the transfer pipe 3 are on the same vertical line. The above structural design ensures that the dispersing cone 13 is installed stably, while enabling the dispersing cone 13 to effectively disperse the falling fertilizer.

[0027] The outer surface of the dispersing cone 13 is set as a mist surface, and the inner surface of the dispersing cone 13 is equipped with internal heating tubes 14 at equal intervals. The above structural design can slow down the speed at which fertilizer falls up and down in the dispersing cone 13. In conjunction with the internal heating tubes 14, the dispersed fertilizer is heated and dried efficiently.

[0028] An air inlet pipe 15 is installed through the bottom of the drying tank 1, and an air nozzle 16 is installed on the vertical part of the air inlet pipe 15. The above structural design can use hot air to dry the fertilizer again.

[0029] The front view of the air intake pipe 15 is "L" shaped. The center of the vertical part of the air intake pipe 15 is on the same vertical line as the center of the drying tank 1. The above structural design ensures that the nozzle 16 on the air intake pipe 15 can blow hot air out evenly.

[0030] The nozzles 16 are distributed at equal angles to the center of the vertical part of the air inlet pipe 15. The nozzles 16 are set at an upward angle. The above structural design allows the hot airflow blown out by the nozzles 16 to move upward, carrying the evaporated moisture to the side exhaust pipe 11 at the top of the drying tank 1 for discharge, thus avoiding the accumulation of water vapor.

[0031] Working principle: When using this device, through... Figure 2 Fertilizer is added into the feeding hopper 2 through the feed pipe 4. The servo motor 6 is started. The servo motor 6 drives the dispersing fan blade 8 and the auger blade 9 to rotate stably through the central shaft 7 and supplies power to the external heating pipe 10. The external heating pipe 10 heats and dries the fertilizer in the feeding hopper 2. The dispersing fan blade 8 stirs the fertilizer to ensure that the fertilizer is heated evenly and moves the fertilizer so that the water vapor generated by evaporation can rise and be discharged through the top exhaust pipe 5.

[0032] The screw conveyor blades 9 transport the pre-dried fertilizer downwards into the drying tank 1. The fertilizer falls onto the dispersing cone 13 and slowly disperses and slides down the curved surface at the top of the dispersing cone 13, supplying power to the internal heating tube 14. The internal heating tube 14 heats the fertilizer on the dispersing cone 13, thus performing secondary drying on the fertilizer.

[0033] Subsequently, the fertilizer falls from the bottom of the dispersion cone 13. The hot air blower connected to the air inlet pipe 15 supplies air to the air nozzle 16 through the air inlet pipe 15. The hot air is discharged upward from the air nozzle 16, which dries the falling fertilizer again and causes the airflow carrying water vapor to move upward. Finally, it is discharged through the side exhaust pipe 11. The dried fertilizer is discharged and collected through the bottom pipe of the drying tank 1. This is the working principle of the fertilizer production drying device.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
