A base is arranged above the universal wheels. A box body is arranged above the base. A fixed platform is arranged above the box body. A control box is mounted on the right side of the box body. A feed peristaltic pump is arranged at the front end of the control box. A display screen is arranged below the feed peristaltic pump. A switch knob is arranged below the display screen. The atomizer is mounted on the upper side of the fixed platform. The special centrifugal spray drying machine for fertilizer processing can realize automatic feeding by connecting the pipeline on the right side of the atomizer with the feed peristaltic pump and connecting the atomizer with the feed machine below.

Hot air in the drying machine can easily enter the atomizer body through the feed machine, thereby affecting the active ingredients of the fertilizer and the product quality. Moreover, the atomizer used in the prior art is common. However, the common atomizer on the market is not stable in atomization effect, which leads to different sizes of fertilizer particles when applied to actual foliage fertilizer processing, thereby affecting the solubility and foliage absorption efficiency.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] A centrifugal nozzle structure, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the nozzle includes a nozzle 10, with a spray head 16 mounted at the bottom. A cooling cylinder 29 is provided inside the nozzle 10. A water inlet valve 30 and a feed pipe 31 are symmetrically fixed on the nozzle 10. A flow guiding assembly is rotatably disposed within the nozzle 10. The flow guiding assembly includes a heat sink 15, a flow guiding column 20, a spline 23, a flow guiding cone 25, a flow guiding spiral 27, and a diffuser cone 28. The spline 23 is fixedly disposed on the bottom surface of the heat sink 15. Both the heat sink 15 and the flow guiding column 20 are rotatably disposed within the nozzle 10. The flow guiding column 20, flow guiding cone 25, flow guiding spiral 27, and diffuser cone 28 are all snapped onto the spline 23. The flow guiding cone 25, flow guiding spiral 27, and diffuser cone 28 are all rotatably disposed within the spray head 16. Figure 2 As shown, a mounting flange 17 is fixedly installed on the top of the spray head 16, and the spray pipe 10 is fixed to the mounting flange 17 by a nut. The spray pipe 10 fixes the spray head 16 through the mounting flange 17. Figure 2 and Figure 5 As shown, a fixed plate 19 is fixedly installed on the top of the nozzle 10, and a motor 14 is fixedly installed on the top surface of the fixed plate 19. The output end of the motor 14 passes through the fixed plate 19 and is connected to the top surface of the heat sink 15. The heat sink 15 is rotatably installed on the top surface of the cooling cylinder 29. Multiple heat dissipation holes 18 are arranged in a circumferential array between the heat sink 15 and the fixed plate 19. Multiple round holes are opened on the heat sink 15, and the round holes communicate with the heat dissipation holes 18.

[0030] Specifically, before use, an external water source is connected through the inlet valve 30 and cooling water is supplied to the cooling cylinder 29. The cooling cylinder 29 is an annular cylinder, and its inner ring is the flow guide section of the flow guide structure, which also serves as the flow space for the fertilizer liquid. When using this device, the motor 14 drives the heat sink 15 and the flow guide structure to achieve centrifugal rotation. The flow guide structure drives the airflow, and the fertilizer liquid entering the cooling cylinder 29 from the feed pipe 31 undergoes initial centrifugal flow through the flow guide column 20 and the flow guide cone 25. After flow guide, the fertilizer liquid is further dispersed by the flow guide spiral 27, and finally... The material is centrifugally ejected through the spiral guide of the diffuser cone 28, and further atomized by the double-layer guide structure, resulting in uniformly distributed fertilizer droplets and uniformly sized particles. This improves the solubility of the fertilizer and the absorption efficiency of the leaves. At the same time, the centrifugal rotation of the guide structure agitates excess heat inside the nozzle 10, which is then dissipated through the round holes and heat dissipation holes 18. Cooling water cools the inside of the nozzle 10 through the wall of the cooling cylinder 29, thus avoiding the impact of hot air on the active ingredients of the fertilizer and ensuring product quality.

[0031] like Figure 2 and Figure 5 As shown, the water inlet valve 30 is connected to the cooling cylinder 29, and the feed pipe 31 passes through the cooling cylinder 29 and is connected to the interior of the spray pipe 10. The bottom surface of the spray head 16 has a circumferential array of multiple material distribution grooves 21, and the bottom curved surface of the spray head 16 has a circumferential array of multiple discharge ports 22; Figure 2 , Figure 3 and Figure 4 As shown, the center of the flow guide column 20, the flow guide cone 25, the flow guide spiral 27 and the flow diffuser cone 28 are all provided with a slot 24, which corresponds to the shape of the spline 23 and engages with the spline 23.

[0032] The working principle is as follows: when the motor 14 drives the heat sink 15 and spline 23 to rotate at high speed, the guide structure generates centrifugal force in the nozzle 10. The guide column 20 and guide cone 25 disperse the fertilizer liquid. The dispersed fertilizer liquid is further dispersed by the guide spiral 27 and flows through the diffuser cone 28. At the same time, the guide spiral 27 ejects a part of the fertilizer liquid to the outlet 22. The diffuser cone 28 further disperses the fertilizer liquid. Then, a part of the fertilizer liquid is dispersed from the distribution trough 21 on the bottom surface of the spray head 16 after being dispersed by the diffuser cone 28. Under the centrifugal action, the fertilizer liquid is atomized.

[0033] like Figure 3 As shown, the slot 24 is composed of a circumferential array of multiple square plates, and the guide cone 25 is composed of a circular plate and multiple trapezoidal plates. The trapezoidal plates are arranged in a circumferential array on the top surface of the circular plate, corresponding to the square plates. Multiple discharge ports 26 are circumferentially arranged on the circular plate, and the discharge ports 26 are located between the trapezoidal plates. Figure 3 and Figure 4As shown, the flow guide spiral 27 is composed of multiple arc-shaped plates, and a conical groove is provided at the bottom of the flow guide spiral 27. The flow diffuser cone 28 is composed of multiple spiral plates and a hollow plate, and the flow diffuser cone 28 corresponds to the conical groove.

[0034] The working principle is as follows: the guide column 20 and the guide cone 25 correspond to each other; the included angle between the square plates corresponds to the included angle between the trapezoidal plates; the discharge port 26 corresponds to the included angle between the trapezoidal plates; the included angle between the arc plates is smaller than that between the discharge port 26; the included angle between the square plates is in a triangular state and is relatively sparse; the included angle between the arc plates is in an arc state and is relatively dense; the included angle between the spiral plates is in a spiral state and corresponds to the included angle between the arc plates. The fertilizer liquid is initially dispersed through the included angle between the square plates, and then flows through the included angle between the arc plates through the discharge port 26. Part of the fertilizer liquid is ejected from the discharge port 22 through the guide spiral 27, and part of the fertilizer liquid is dispersed from the distribution trough 21 through the dispersion cone 28.

[0035] A foliar fertilizer spray drying device includes a feeder 11, such as Figure 1 and Figure 5 As shown, a peristaltic pump 12 is fixedly installed on one side of the feeder 11. A pipeline 13 is fixedly installed between the peristaltic pump 12 and the nozzle 10. The pipeline 13 is connected to the feed pipe 31. By setting the centrifugal nozzle structure described above, the device has the characteristics of heat dissipation and uniform particle size.

[0036] It is worth noting that the feeder 11 and the feed peristaltic pump 12 are fixed by a fixed platform. A dryer is installed on the fixed platform. The dryer dries the atomized material in the feeder 11. The feed peristaltic pump 12 is connected to the feed pipe 31 through the pipeline 13 to achieve automatic feeding. The feeder 11, the feed peristaltic pump 12, the fixed platform, the dryer and the pipeline 13 are all disclosed in detail in the prior art in a centrifugal spray dryer for fertilizer processing (CN217612934U), and will not be repeated here.
