The setting of multiple drying plates avoids the situation where the upper materials are dry and the lower materials are still wet due to excessive material accumulation. The design of multi-layer drying plates increases the amount of materials dried each time, because the multi-layer setting mainly increases the contact area between the materials and the hot air, making the overall drying effect of the materials better. For the same drying time, the efficiency of drying a single-layer stack of materials is much lower than the material drying efficiency of multi-layer drying plates, effectively saving energy consumption.

[0039] Reference Figure 1~Figure 2, which is the first embodiment of the utility model, proposes a hot air circulation drying furnace, including a furnace body 1, the furnace body 1 has a cavity 101, the cavity 101 has an air inlet 102, the heating component 2 is arranged in the cavity 101 and is located at the lower side, the drying box 3 is arranged in the cavity 101 and is located at the upper side, the drying box 3 has a drying chamber 301, the drying chamber 301 has a hot air inlet 302 and a hot air outlet 303, the hot air inlet 302 is connected to the cavity 101, the rotating member 4 is rotatably arranged in the drying chamber 301, and is located in the middle of the drying box 3, the drying plate 5 is arranged on the rotating member 4, and there are a plurality of drying plates 5, which divide the drying chamber 301 into a plurality of isolation chambers 304.

[0040] In this embodiment, the cavity 101 contained in the furnace body 1 is used as the main space for hot air circulation. The cavity 101 is provided with an air inlet 102 to provide an entrance for gas and ensure the introduction of gas. The heating component 2 is arranged at the bottom of the cavity 101 to effectively distribute heat energy, provide a uniform and stable heat source for the furnace environment, and promote hot air circulation. The drying box 3 is located at the upper part of the cavity 101, with a built-in drying chamber 301, and is specially designed with a hot air inlet 302 and a hot air outlet 303 to form a closed hot air circulation channel to ensure that the introduction of hot air contacts the material. The rotating member 4 in the drying chamber 301 is cleverly designed and is located in the middle of the drying box 3. A drying plate 5 is installed on it. These drying plates 5 separate multiple isolation chambers 304, so that the hot air penetrates each material more evenly, improving the drying efficiency and uniformity. The arrangement of several drying plates 5 divides the drying chamber 301 into multiple independent chambers through the rotation on the rotating member 4, ensuring that the hot air can evenly penetrate each piece of material, improving the drying efficiency, reducing energy consumption, and optimizing the drying effect. In summary, the hot air circulation furnace, through the careful design of the heating component 2, the drying box 3, the rotating part 4 and the drying plate 5, realizes the efficient circulation of hot air and material drying, improves the drying efficiency, and demonstrates the innovation and practical value of the design. Compared with the hot air circulation furnace of the prior art, through the design of the rotating part 4, the dried material can be evenly contacted with the hot air, avoiding the situation that the drying is completed at the hot air inlet 302 of the existing drying furnace, but the hot air outlet 303 is still unable to complete the drying. The rotating part 4 drives the drying plate 5 to rotate, so that the material is heated more evenly. The setting of multiple drying plates 5 avoids the situation that the upper material is dry and the lower material is still wet due to the excessive accumulation of materials. Through the design of the multi-layer drying plate 5, the amount of material dried each time is increased, because the multi-layer setting mainly increases the contact area between the material and the hot air, so that the overall drying effect of the material is better.

Such a design not only optimizes the structural strength distribution, but also ensures the balance during rotation, and the force of each drying plate 5 is balanced. The stepped portion 402 has a keyway 403 on the outside, and the drying plate 5 is designed with a key bar portion 501, and the keyway 403 cooperates with the key bar portion 501. This design ensures that the drying plate 5 is stably fixed during rotation without sliding, and allows flexible installation and disassembly, simplifying maintenance and adjustment. In summary, the hot air circulation furnace improves the stability of the installation and the flexibility of rotation of the drying plate 5 through the stepped design of the rotating shaft 401 and the exquisiteness of the keyway 403 and the key bar, and is convenient for the maintenance of the drying plate 5.

When the locking portion 407 is unengaged with the clamping piece 405, the second shaft body 406 can slide relative to the first shaft body 404, and the upper ends of the first shaft body 404 and the second shaft body 406 are provided with a key groove 403.

[0048] In this embodiment, the rotating shaft 401 is designed as a first shaft body 404 that can rotate and move in the drying chamber 301, and the middle and lower ends are provided with a clamping member 405, which provides a clamping point for the locking member 407 of the second shaft body 406, thereby enhancing the flexibility and stability of the structure. The second shaft body 406 is designed to slide on the first shaft body 404, and a locking member 407 is provided at the upper end, which can be clamped or unlocked with the clamping member 405 of the first shaft body 404.

The sliding design of the first shaft 404 and the second shaft 406 makes it more convenient to load and unload materials. When the lower end clamp 405 of the first shaft 404 is engaged with the locking part 407 of the second shaft 406, the distance between the two drying plates is large, which is convenient for loading and unloading. When the middle clamp 405 of the first shaft 404 is engaged with the locking part 407 of the second shaft 406, the space occupied by the drying plates is effectively reduced. Several second shafts 406 can also be connected to each other, so that the number of simultaneous drying in the drying furnace is increased.
