[0036] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0037] The structure and function of this utility model are as follows:

[0038] like Figures 1-10 As shown, a drying device includes a drying chamber 2. A detection component 8 is installed on the drying chamber 2 to detect the temperature and pressure difference inside the drying chamber 2. An air inlet box 1 is installed on one side of the drying chamber 2, with its inlet connected to the outlet of a fan 5. A heating tube 6 is installed inside the air inlet box 1. An exhaust box 3 is installed on the other side of the drying chamber 2, with a cyclone separator 9 installed at its exhaust outlet. Two spaced-apart side plates 19 are installed inside the drying chamber 2, dividing the interior space into a drying space. At least one air distribution plate 16 and a tray assembly 18 are installed within the drying space, with the tray assembly 18 supporting the material. Each side plate 19 has an upper opening 20 and a lower opening 21 spaced from top to bottom on its end face. A damper 15 is arranged on the outside of the drying chamber 2. A single damper 15 is slidably installed inside the drying chamber 2 and connected to the output end of the cylinder 13. The fan 5 draws air into the air inlet box 1, and the heating tube 6 is energized to heat up the air introduced into the air inlet box 1 by the fan 5 to form hot air. The single cylinder 13 drives the corresponding damper 15 to move in a straight line in the vertical direction, so that the damper 15 covers the upper opening 20 or lower opening 21 on the end face of the corresponding side plate 19. This allows the hot air to flow from top to bottom through the upper opening 20 of one side plate 19 and the lower opening 21 of the other side plate 19, or from bottom to top through the lower opening 21 of one side plate 19 and the upper opening 20 of the other side plate 19, thereby drying the material in the drying chamber. The hot air flowing out of the drying chamber enters the cyclone separator 9 through the exhaust box 3 for dust removal and is then discharged into the atmosphere. By setting up an air inlet box 1, a drying box 2, an exhaust box 3, and a fan 5, the material on the tray can be dried efficiently and evenly. Its structure is compact, occupies a small area, and has low energy consumption, effectively reducing testing and production costs. By setting up a detection component 8, the material drying process parameters can be obtained, which facilitates the formulation of drying process parameters, and the resulting drying parameter curve can provide a basis for the design of large-scale drying production lines.

[0039] The tray assembly 18 and the air distribution plate 16 are arranged vertically at intervals, with the air distribution plate 16 positioned above, below, or both above and below the tray assembly 18. In this invention, when hot air flows from top to bottom through the drying space, an air distribution plate 16 is positioned above the tray assembly 18, or both above and below the tray assembly 18; when hot air flows from bottom to top through the drying space, an air distribution plate 16 is positioned below the tray assembly 18, or both above and below the tray assembly 18.

[0040] The tray assembly 18 is installed in the drying space via the material support 17.

[0041] The tray assembly 18 includes at least one tray, with several slots formed on the end face of each tray; each slot is either round or oval in shape. Figure 4 As shown, the tray has various hole types and opening ratios, which can be used to conduct drying tests on various materials. During the test, the thickness of the material can be adjusted according to different materials, so that the drying device can dry products such as roasted sunflower seeds, dried fruits and vegetables, cellulose acetate sheets, and synthetic rubber, improving the flexibility of the drying device and making it suitable for applications in the food, chemical fiber, and chemical industries.

[0042] Several circular through holes are formed on the end face of each individual air distribution plate 16. The air distribution plate 16 improves the uniformity of hot air distribution within the drying space, ensuring that hot air passes evenly through the material within the drying space; furthermore, such as Figure 3 As shown, the air distribution plate 16 has various specifications. Under the same conditions, the influence of air distribution plates 16 with different opening ratios on the drying effect can be tested. The experimental results can be applied to the optimization design of air distribution plates in large-scale drying equipment.

[0043] The structure of the air inlet box 1 is as follows: it includes a first box 101, a second box 102 and a third box 103 connected in sequence. The first box 101 is conical and is used to connect to the air outlet of the fan 5. The third box 103 is used to connect to the drying box 2. The heating tube 6 is installed in the second box 102.

[0044] A connector 104 is installed on the first chamber 101. By setting the connector 104, external steam can be connected to increase the air humidity in the drying space, thereby facilitating the simulation of drying tests with high moisture content requirements.

[0045] The first housing 101 is connected to the air outlet of the fan 5 via the first connecting pipe 11, and the air outlet of the exhaust box 13 is connected to the air inlet of the cyclone separator 9 via the second connecting pipe 12. The second connecting pipe 12 is an elbow pipe.

[0046] A temperature and humidity sensor is installed on the exhaust box 3 to detect the temperature and humidity inside the exhaust vent of the exhaust box 3 in real time.

[0047] The detection component 8 includes a differential pressure gauge 803. One input terminal of the differential pressure gauge 803 is connected to a first detection port group on the drying chamber 2 via a first detection connecting pipe group 801, and the other input terminal is connected to a second detection port group on the drying chamber 2 via a second detection connecting pipe group 802. Vertically, the first detection port group is positioned below the second detection port group. The component also includes two temperature sensors 804 and two wind speed sensors 805, both vertically spaced on the drying chamber 2. The differential pressure gauge 803 can detect the pressure difference between the upper and lower parts of the drying space, enabling it to acquire real-time pressure parameters within the drying space during the experiment, thus determining the pressure changes within the drying space under different experimental conditions. The two temperature sensors 804 are used to detect the temperature of the hot air entering and exiting the drying space, respectively, thereby acquiring real-time temperature change values. The two wind speed sensors 805 are used to detect the wind speed of the hot air entering and exiting the drying space, respectively.

[0048] Each damper 15 slides against the inner wall of the drying chamber 2 via a guide block assembly 14. By providing the guide block assembly 14, the movement stability of the damper 15 can be improved.

[0049] A material hopper 10 is installed at the bottom of the cyclone separator 9. The material hopper 10 is installed at the drain port of the cyclone separator 9. The material hopper 10 is used to store the material debris separated by the cyclone separator 9, so as to prevent the debris from falling into the production site and effectively ensure the cleanliness of the production site.

[0050] In this invention, the fan 5 is a variable frequency fan with adjustable air volume, which allows the air volume requirement for material drying to be determined based on the drying device test, providing a basis for determining air volume parameters and selecting fans in large-scale drying equipment.

[0051] Heating tube 6 uses electric heating, and its heating temperature range is 60℃-200℃. The optimal temperature range for drying different materials can be determined through experiments, and the experimental results can be directly used to formulate parameters for large-scale drying equipment.

[0054] In the top-in, bottom-out working mode, the damper 15 located near the air inlet box 1 moves in a straight line in the vertical direction under the drive of the corresponding cylinder 13, thereby blocking the lower opening 21 on the adjacent side plate 19.

[0055] The air door 15 arranged close to the air exhaust box 3 is driven by the corresponding air cylinder 13 to move linearly in the vertical direction, thereby shielding the upper opening 20 on the side plate 19 adjacent thereto;
