[0024] 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.

[0025] Example 1: Please refer to Figure 1 - Figure 6This utility model provides a technical solution: a circulating fan for persimmon production, including a housing 1. An air inlet pipe 2 is fixedly installed at one end of the housing 1 by bolts 17. A tapered guide tube 21 is fixedly installed at one end of the air inlet pipe 2. A limiting groove 22 is formed in the middle of the air inlet pipe 2. A gear ring 23 is rotatably installed in the middle of the limiting groove 22. A turntable 24 is fixedly installed in the middle of the gear ring 23. Arc-shaped guide grooves 25 are formed around the outer periphery of the turntable 24. A fixed plate 26 is fixedly installed on the other side of the middle of the air inlet pipe 2. A straight guide groove 27 is formed around the outer periphery of the fixed plate 26. A sliding rod 29 is slidably engaged in the middle of the multiple arc-shaped guide grooves 25. An adjusting plate 28 is fixedly installed at one end of each sliding rod 29. A sliding rod 30 is fixedly installed at one end of each adjusting plate 28. A gear 33 is provided on one side of the upper end of the air inlet pipe 2. A gear 33 is fixedly installed in the middle of the other end of the air inlet pipe 2. A wind speed sensor 35 is fixedly installed in the middle of the fixed rod 34 and gear 33. A U-shaped plate 36 is fixedly installed around the outer side of the air inlet pipe 2. The two ends of the U-shaped plate 36 are fixedly connected to the two sides of the air inlet pipe 2 that are divided by the air inlet pipe 2. Two fixed plates 31 are fixedly installed on one side of the upper end of the air inlet pipe 2. A motor 32 is fixedly installed in the middle of the two fixed plates 31. The output end of the motor 32 is fixedly connected to one end of the gear 33. The gear 33 meshes with the gear ring 23. The slide rod 20 is slidably engaged in the middle of the corresponding linear guide groove 27. The smaller diameter end of the tapered duct 21 is close to the turntable 24. The wind speed sensor 35 and the motor 32 are electrically connected. Ventilation opening 2 37 is opened in the middle of the air inlet pipe 2, tapered duct 21, turntable 24 and fixed plate 26. Ventilation opening 2 37 is connected to ventilation opening 12. When multiple adjusting plates 28 are fully spliced, ventilation opening 2 37 can be completely closed.

[0026] In this embodiment, the smaller end of the conical duct 21 faces the entire circulating fan, utilizing the Venturi effect to accelerate air intake. Combined with the precise air control of the regulating plate 28, this ensures concentrated airflow, reduces air volume loss, and allows for flexible control of wind speed, keeping the fan operating at high efficiency, reducing energy consumption while improving air circulation efficiency within the drying chamber. The motor 32 drives the gear ring 23 and turntable 24 in conjunction with the regulating plate 28, allowing real-time control of the opening of the second ventilation opening 37. This precisely matches the air volume requirements at each stage of persimmon production, such as high air volume for initial dehydration, medium air volume for mid-stage concentration, and low air volume for later shaping. This avoids the lag in traditional fan air volume adjustment, improving the uniformity of persimmon taste and color. (Wind speed sensor...) The device 35 is electrically linked to the motor 32, and can be linked with an external control system. This allows the device to automatically adjust the opening of the regulating plate 28 according to the actual wind speed, achieving closed-loop control of automatic air adjustment in real time, reducing the workload of manual operation, and adapting to the needs of continuous industrial production of persimmons. When the regulating plate 28 is fully spliced, it can close the ventilation opening 2 37, which can cut off the airflow during equipment maintenance and quickly adjust the air path when changing batches of persimmons, avoiding fluctuations in temperature and humidity in the drying room and reducing the defect rate. At the same time, the regulating components such as the toothed ring 23, the turntable 24, and the regulating plate 28 are all integrated inside the air inlet pipe 2. Combined with the installation design of the square casing 1, it can be directly connected to the ventilation system of the persimmon drying room without additional space modification, adapting to the installation needs of drying rooms of different sizes.

[0027] Example 2: As Figure 1 - Figure 3 As shown, screw holes 15 are provided at the four corners of the outer side of the housing 1. A right-angle plate 16 is provided on one side of each screw hole 15. Bolts 17 are threaded to the middle of both ends of each right-angle plate 16. The right-angle plates 16 are connected by the cooperation of the bolts 17 and the screw holes 15. An air guide duct 11 is fixedly installed in the middle of the housing 1. A ventilation opening 12 is provided in the middle of the air guide duct 11. An air supply assembly 13 is fixedly installed in the middle of the air guide duct 11. A mesh cover 14 is fixedly installed at the other end of the air guide duct 11.

[0028] In this embodiment, the screw holes 15 at the four corners of the housing 1, combined with the right-angle plates 16 and bolts 17, allow users to add or remove the right-angle plates 16 according to actual installation needs. This enables quick splicing or disassembly of components such as the fan, the drying room ventilation system, and the walls. It allows for independent installation of a single fan or the combination of multiple fans into a ventilation unit, adapting to drying rooms of different sizes and greatly improving the installation flexibility of the equipment. The design of the air guide duct 11 and the vent 12 guides the airflow to be concentrated through the air supply component 13, reducing the dispersion loss of airflow within the housing 1, improving the air supply efficiency of the fan, and allowing hot air to be delivered more accurately to each area of ​​the drying room, ensuring that the persimmons are heated or dehydrated evenly. The mesh cover 14 at the end of the air guide duct 11 prevents foreign objects from entering the fan and avoids the air supply component 13, such as the impeller, from being blocked and damaged. It also prevents personnel from accidentally touching rotating parts, improving the safety of equipment operation.

[0029] Working principle:

[0030] like Figure 1 - Figure 6 As shown, the screw holes 15 at the four corners of the housing 1, together with the right-angle plate 16 and bolts 17, allow for the independent installation of a single fan or the splicing of multiple fans into a ventilation unit, depending on the size of the drying chamber. This allows for quick connection to the ventilation system of the drying chamber without the need for additional space modifications. In use, external air first enters the conical duct 21. Utilizing the Venturi effect, the conical duct 21 compresses the airflow after it enters from the larger diameter end, thereby increasing the flow velocity and concentrating it towards the interior of the air inlet duct 2. The accelerated airflow then enters the air guide duct 11 inside the housing 1 through the second ventilation port 37 of the air inlet duct 2. The air guide duct 11 further constrains the airflow path through the first ventilation port 12, concentrating the airflow towards the air supply assembly 13 and reducing airflow dispersion losses within the housing 1. Driven by the air supply assembly 13, the concentrated airflow is delivered into the persimmon drying chamber, achieving hot air circulation within the chamber. The mesh cover 14 at the end of the air guide duct 11 prevents foreign objects from entering the fan and protects rotating parts.

[0031] During the process, the wind speed sensor 35 installed in the air inlet duct 2 detects the air intake speed in real time and transmits the data to the control system. The control system can send adjustment commands to the motor 32 according to the preset wind speed thresholds for the current production stage of persimmons, such as the initial dehydration requiring a large air volume and the later shaping requiring a small air volume. The motor 32 drives the gear 33 to rotate, and the gear 33 meshes with the gear ring 23, causing the gear ring 23 to rotate within the limiting groove 22 of the air inlet duct 2; the gear ring 23 will then rotate in conjunction with the turntable 24, and the arc-shaped guide groove 25 on the turntable 24 will cause the slide rod 29 to slide, thereby pulling the adjustment plate 28 to move. The slide rod 30 at one end of the adjustment plate 28 will slide along the straight guide groove 27 of the fixed plate 26, causing multiple adjustment plates 28 to open and close synchronously, changing the opening degree of the ventilation opening 37, and achieving precise adjustment of the air volume. A larger opening degree results in a higher air volume, and vice versa. When a shutdown for maintenance or batch switching of persimmons is required, the regulating plate 28 can be completely connected to seal the ventilation opening 37, cutting off airflow and preventing fluctuations in the drying room environment. The entire workflow achieves efficient airflow delivery and automatic airflow adaptation to the process and flexible equipment installation, accurately matching the needs of the entire persimmon production process while improving efficiency and reducing costs, making it highly practical.
