DETAILED DESCRIPTION

[0043] Preferred embodiments of the present application will be described in more detail with reference to the drawings. Although the preferred embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present application is more thorough and complete, and the scope of the present application is fully conveyed to those skilled in the art.

[0044] In recent years, reverse light illumination technology has been introduced into the field of solar heat collection as an innovative idea. This technology aims to direct solar radiation energy to the collector through reflection, scattering and other non-direct illumination methods, thereby overcoming the limitations of direct illumination methods. However, existing reverse light illumination solar heat collection devices have low reflection efficiency and inflexible adjustment, making it difficult to meet the high-efficiency heat collection needs under different illumination conditions.

[0045] Based on this, the present application provides a drying device with uniform ventilation.

[0046] Referring to Figs. 1-8, the present application provides a drying device with uniform ventilation, comprising:

[0047] The drying box 2 is provided with a plurality of drying chambers 21, and the drying chamber 21 is provided with a drying tray 24. Specifically, the drying box 2 is designed in the shape of a cuboid, and is internally partitioned into a plurality of independent drying chambers 21, each of which is used to place the agricultural products to be dried. The size and number of the drying chambers 21 can be adjusted according to the actual drying requirements to adapt to different batches and types of agricultural products. For example, the drying chambers 21 can be 5, and the 5 drying chambers 21 are arranged in the drying box 2 along the height direction of the drying box 2. The drying tray 24 is used to carry the agricultural products to be dried, and ensures that the agricultural products can be uniformly heated and ventilated during the drying process. More preferably, the drying tray 24 can be a square net structure, which facilitates the flat and uniform filling of the agricultural products to be dried in the drying tray 24, and is beneficial to the uniformity of the dried agricultural products.

[0048] One side of the drying tray 24 is provided with an air uniformizing cavity 1, and the air uniformizing cavity 1 is provided with an air inlet 14 and a first air outlet 15, and the first air outlet 15 communicates with the drying chamber 21. The air uniformizing cavity 1 is provided with a first flow guide assembly, and the first flow guide assembly includes a plurality of flow guide units. Each flow guide unit includes at least one flow guide plate and at least one flow guide driving device, and the flow guide driving device is used to drive the flow guide plate to rotate. A plurality of flow guide units are arranged in the air uniformizing cavity 1 along the flow direction of the airflow.

[0049] The air uniformizing cavity 1 is adjacent to the drying chamber 21 and is used to guide the airflow to be uniformly distributed into the drying chamber 21. The first flow guide assembly is used to guide and distribute the airflow entering the air uniformizing cavity 1. The flow guide plate is designed to be adjustable in angle and position, so as to be adjusted according to the actual flow condition of the airflow, so as to realize the uniform distribution of the airflow. The flow guide driving device is used to drive the flow guide plate to rotate, and can be realized by a motor, a pneumatic cylinder or other driving modes. A plurality of flow guide units are arranged in the air uniformizing cavity 1 along the flow direction of the airflow, so as to ensure that the airflow can be sufficiently guided and distributed when passing through the air uniformizing cavity 1.

[0050] The uniform ventilation drying device can drive the flow guide plate to rotate, and can guide the airflow when the flow guide plate rotates at different angles. During use, the flow guide driving device drives the flow guide plate to rotate, effectively guiding and uniformly distributing the airflow entering the drying box 2, ensuring the uniformity of airflow distribution in the drying chamber 21. Uniform airflow distribution helps to heat and dehydrate agricultural products more evenly during the drying process, avoiding local overheating or insufficient drying, thereby significantly improving drying efficiency and overall product quality. Because the drying process is more efficient and uniform, the energy consumption and time required for repeated drying or over-drying due to uneven drying are reduced, which helps to reduce the drying cost of agricultural products in the long run. In addition, the drying device of the present application can adapt to the drying needs of different types and sizes of agricultural products by adjusting the configuration of the flow guide assembly, improving the versatility and practicality of the equipment.

[0051] Specifically, the present embodiment provides a specific structure of the first flow guide assembly. The specific structure is as follows:

[0052] The first flow guide assembly comprises a first flow guide unit 11, a second flow guide unit 12 and a third flow guide unit 13 arranged in sequence along the airflow direction;

[0053] The first flow guide unit 11 is arranged close to the air inlet 14, the third flow guide unit 13 is arranged close to the first air outlet 15, and the second flow guide unit 12 is arranged between the first flow guide unit 11 and the third flow guide unit 13.

[0054] Further, the first flow guide unit 11 comprises a first motor and a first flow guide plate 111, the first flow guide plate 111 is rotatably arranged in the air uniformizing chamber 1, one end of the first flow guide plate 111 is provided with a first spur gear 112, the output end of the first motor is provided with a first drive gear 113, and the first drive gear 113 is engaged with the first spur gear 112. The first motor is engaged with the first spur gear 112 at one end of the first flow guide plate 111 through the first drive gear 113, so that the first motor drives the first flow guide plate 111 to rotate when the first motor rotates.

[0055] The second flow guide unit 12 comprises a second motor, a first transmission rack 122 and two second flow guide plates 121, and the two second flow guide plates 121 are rotatably arranged in the air uniformizing chamber 1; one end of each second flow guide plate 121 is provided with a second spur gear 123, the first transmission rack 122 is movably arranged in the air uniformizing chamber 1, and the first transmission rack 122 is engaged with the two second spur gears 123; the second motor is fixed in the air uniformizing chamber 1, the output end of the second motor is provided with a second drive gear 124, and the second drive gear 124 is engaged with the first transmission rack 122.

[0056] The first transmission rack 122 is movably arranged in the air equalizing cavity 1, and specifically, the first transmission rack 122 is arranged with a guide groove, the air equalizing cavity 1 is arranged with a guide block, the guide block is clamped into the guide groove, so that the first transmission rack 122 can move along the length direction of the guide groove. When the second driving gear 124 arranged at the output end of the second motor is driven to move, it can drive the two second guide plates 121 to synchronously rotate.

[0057] The second guide unit 12 comprises a third motor, a second transmission rack 133 and three third guide plates 131, and the two third guide plates 131 are rotatably arranged in the air equalizing cavity 1. One end of each third guide plate 131 is arranged with a third spur gear 132, the second transmission rack 133 is movably arranged in the air equalizing cavity 1, and the second transmission rack 133 is engaged with the two third spur gears 132. The third motor is fixed in the air equalizing cavity 1, the output end of the third motor is arranged with a third driving gear 134, and the third driving gear 134 is engaged with the second transmission rack 133. Similarly, the moving mode of the second transmission rack 133 can be the same as that of the first transmission rack 122, and the movement of the second transmission rack 133 is realized through the cooperation of the guide groove and the guide block. The three guide units of the present application are driven by three different motors, so that the adjustment of the guide plates of each guide unit is independent of each other, which guarantees the independence of the air direction adjustment, can adjust for different products and different needs, thereby improving the application range of the device.

[0058] More specifically, in the longitudinal section along the height direction of the air equalizing cavity 1, the first guide plate 111, the second guide plate 121 and the third guide plate 131 are arranged in an isosceles triangle; wherein the position of the first guide plate 111 is the apex of the isosceles triangle. The three third guide plates 131 are distributed on the base of the isosceles triangle, and the two second guide plates 121 are distributed on the waist line of the isosceles triangle.

[0059] The first guide plate 111, the second guide plate 121 and the third guide plate 131 are arranged in an isosceles triangle in the air equalizing cavity 1, which makes the air flow pass through multiple guiding and distribution before entering the drying chamber 21, thereby realizing the uniform distribution of the air flow.

[0060] The first guide plate 111 is located at the top of the isosceles triangle and plays a major role in guiding and distributing the airflow, helping to evenly guide the airflow to the bottom of the isosceles triangle, i.e., the position of the three third guide plates 131. By adjusting the positions and angles of the first guide plate 111, the second guide plate 121, and the third guide plate 131, the drying needs of different types and sizes of agricultural products can be met. This flexible design enables the drying device to adapt to various drying conditions, improving the versatility and practicality of the equipment.

[0061] In a more specific embodiment, a second guide assembly 16 is provided at each first air outlet 15.

[0062] The second guide assembly 16 includes a plurality of sheet-shaped guide plates 161 and a plurality of fourth motors. Each sheet-shaped guide plate 161 is arranged in parallel. One end of each sheet-shaped guide plate 161 is provided with a fourth spur gear 162. Each fourth motor corresponds to one sheet-shaped guide plate 161. The output end of each fourth motor is provided with a fourth drive gear 163, which is engaged with the fourth spur gear 162.

[0063] The second guide assembly 16 is composed of a plurality of sheet-shaped guide plates 161 and a plurality of fourth motors. Each sheet-shaped guide plate 161 can be independently driven to rotate by the corresponding fourth motor.

[0064] This design allows the airflow to be more finely adjusted and guided before entering the drying chamber 21, ensuring that the airflow is evenly distributed to every corner of the drying chamber 21. By adjusting the angle and position of the sheet-shaped guide plate 161, the direction and speed of the airflow can be precisely controlled, avoiding the problem of local overheating or insufficient drying in the drying chamber 21. Uniform airflow distribution helps to improve the uniformity of agricultural product drying and ensures the consistency of product quality.

[0065] Specifically, a support 25 is provided in each drying chamber 21, and the drying tray 24 is arranged on the support 25. The bottom of the drying tray 24 is provided with a partition cavity 26, the two sides of the partition cavity 26 are provided with a partition cavity 26 inlet, and the top of the partition cavity 26 is provided with an air outlet hole 261, which communicates with the drying tray 24.

[0066] The cavity 26 is internally provided with vertical flow guide plates 263, which include horizontal plates 2631 fixed in the cavity 26 and inclined plates 2632 arranged on one side of the horizontal plates 2631 and forming an angle α between them, 30° < α < 45°. The vertical flow guide plates 263 enable the gas to flow vertically upward after entering the drying chamber 21 horizontally, pass through the air outlet holes 261 of the cavity 26, and flow to the drying disc 24 to dry the crops.

[0067] The design of the vertical flow guide plates 263 enables the gas to change from horizontal flow to vertical upward flow after entering the drying chamber 21. The optimization of the airflow path helps to ensure that the airflow can uniformly flow to the drying disc 24 through the air outlet holes 261, thereby uniformly drying the crops. The vertical upward airflow directly blows to the crops through the air outlet holes 261, increasing the contact area and time of the airflow with the crops, thereby improving the drying efficiency. Compared with the traditional design, this airflow mode can quickly remove the moisture on the surface of the crops, reducing the drying time.

[0068] Since the airflow can uniformly flow to the drying disc 24 through the air outlet holes 261, the problem of local overheating or insufficient drying in the drying chamber 21 can be reduced. This helps to ensure that the crops maintain a consistent drying degree during the drying process, improving the product quality.

[0069] The present application enables the air speed at the air outlet holes 261 to be uniform through the design of the vertical flow guide plates 263.

[0070] Further, the support 25 is provided with temperature sensors, humidity sensors, and air speed sensors on opposite sides, and the sensors on the opposite sides of the support 25 are staggered in the vertical direction. The temperature sensors, humidity sensors, and air speed sensors on the opposite sides of the support 25 can monitor the environmental temperature, humidity, and airflow speed in the drying chamber 21 in real time. The sensors are staggered in the vertical direction, which helps to obtain environmental data at different height levels in the drying chamber 21, improving the accuracy and comprehensiveness of the monitoring. Through real-time monitoring of the environmental data, the actual conditions in the drying chamber 21 can be accurately mastered, and the drying process can be adjusted and optimized in real time. For example, when the temperature or humidity in the drying chamber 21 is too high, the posture of the first flow guide assembly and the second flow guide assembly 16 can be adjusted in time to change the angle of different flow guide plates to maintain a suitable environment in the drying chamber 21. Precise environmental monitoring and real-time drying process adjustment help to ensure that the agricultural products maintain the best state during the drying process. This can reduce the problem of uneven drying or product quality decline caused by environmental fluctuations, improving the overall quality of the agricultural products.

[0071] Further, each of the drying chambers 21 is provided with a second air outlet 22 on one side, and the second air outlet 22 is provided with an iris structure switch 23 capable of controlling the opening size.

[0072] The iris structure switch 23 can control the size of the second air outlet 22 according to actual needs, realizing fine adjustment of air flow. Combined with the data monitored in real time by the sensor, the drying device can more intelligently adapt to different drying conditions and agricultural product needs. The iris structure switch 23 can be adjusted in size through the control center of the drying device. In actual application, the size of the iris structure switch 23 can be adjusted in two ways, one is to adjust to the size required by the drying chamber 21 through the control center to realize automatic drying, and the other is to manually adjust the size of the iris structure switch 23. More specifically, the iris structure switch 23 of the present application adopts a mechanical iris structure, which includes a frame, a plurality of petals are arranged in the frame along the circumferential direction of the frame, a wind passage is formed in the middle of the petals for air flow to pass through, and the size of the wind passage can be adjusted by adjusting the position of the petals, so as to change the air flow circulation speed in the drying chamber 21 as needed.

[0073] In actual application, when the drying chamber 21 needs to be heated, the iris structure switch 23 on the second air outlet 22 corresponding to each layer of the drying chamber 21 is tightly closed, and the air flow of the drying chamber 21 cannot flow out, so that the inside of the drying chamber 21 is rapidly heated. When the drying chamber 21 needs to be cooled, dusted or reduced in humidity, the corresponding iris structure switch 23 is opened to discharge the gas in the drying chamber 21. More specifically, after the gas in the drying chamber is discharged, it can be discharged to the outside air or to the tail gas treatment equipment for tail gas treatment.

[0074] Embodiment 2

[0075] This embodiment is improved on the basis of embodiment 1.

[0076] In this embodiment, one side of the drying chamber 21 is provided with a sliding plate 3, and the sliding plate 3 is provided with a wind collecting cavity 31, and the wind collecting cavity 31 is in communication with each second air outlet 22; the wind collecting cavity 31 arranged inside the sliding plate 3 not only plays a role in collecting gas, but also optimizes the space utilization through its design. This compact structure design makes the whole device more compact and efficient.

[0077] The bottom of the drying chamber 21 is provided with a dust removal chamber 4, and the wind collecting cavity 31 is in communication with the dust removal chamber 4 through a dust removal inlet 41; the dust removal chamber 4 is provided with a metal fence 42, and the metal fence 42 is connected with an electrostatic generating device;

[0078] The dust removal chamber 4 is provided with a third air outlet 43 on one side, and an exhaust device 44 is arranged at the third air outlet 43. The exhaust device 44 comprises a fan 443, a support frame 442 and a protective net 441. The support frame 442 is arranged at the third air outlet 43, and the fan 443 and the protective net 441 are both fixed on the support frame 442. The protective net 441 is arranged on one side of the fan 443.

[0079] In actual application, the gas discharged from the second air outlet 22 can flow into the dust removal chamber 4 from the air collecting cavity 31 inside the sliding plate 3, and then be discharged to the outside of the entire device after electrostatic dust removal. In another embodiment, the sliding plate 3 is in sliding cooperation with the outer wall of the drying chamber 21. When it is necessary to quickly remove the gas in the drying chamber 21, the sliding plate 3 can be removed, so that the gas in the drying chamber 21 is directly discharged from the opening of the iris structure switch 23.

[0080] By arranging the dust removal chamber 4 at the bottom of the drying chamber 21 and connecting the air collecting cavity 31 with the dust removal chamber 4, the gas discharged from the second air outlet 22 can flow into the dust removal chamber 4 for electrostatic dust removal treatment.
