[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1-5 The hot air circulation box shown includes a tank 1, a connecting cylinder 2, and a drive assembly 3. One end of the tank 1 is rotatably connected to the connecting cylinder 2. The drive assembly 3 is installed at the bottom of the outer wall of the connecting cylinder 2. A central tube 4 is installed through the interior of both the tank 1 and the connecting cylinder 2. A sealing plate 5 is rotatably connected to the bottom of the tank 1. Multiple venting plates 6 are provided at the center of the interior of the tank 1. One end of the tank 1 is interconnected with the interior of the connecting cylinder 2. One end of the central tube 4 is connected through the interior of the connecting cylinder 2 and is interconnected with the end of the tank 1 away from the connecting cylinder 2. The drive assembly 3 includes a fixed gear ring 301 and a drive gear 302. The fixed gear ring 301 and the drive gear 302 mesh with each other. The fixed gear ring 301 is fixedly connected to the outer wall of the connecting cylinder 2. A drive motor 303 is installed at the bottom of the sealing plate 5 near the end of the connecting cylinder 2.

[0027] likeFigure 3 , Figure 4 As shown, the bottom of the tank 1 is flat, and a rectangular hole corresponding to the size of the sealing plate 5 is opened at the bottom of the tank 1. The sealing plate 5 fits into the rectangular hole at the bottom of the tank 1, and a connecting shaft 501 is fixedly connected to one side of the sealing plate 5. The connecting shaft 501 is rotatably connected to one side of the bottom of the tank 1. The drive motor 303 is fixedly connected to the outer wall of the sealing plate 5. The side of the sealing plate 5 away from the connecting shaft 501 is fixedly attached to the outer wall of the tank 1 by a buckle. The power output end of the drive motor 303 is fixedly connected to the internal center of the drive gear 302. When the drive assembly 3 is started, the drive motor 303 rotates, causing the drive gear 302 to rotate. This causes the drive gear 302 to rotate around the outer wall of the fixed gear ring 301, which in turn causes the drive motor 303 to rotate around the outer wall of the connecting cylinder 2. This causes the tank 1 and the sealing plate 5 to rotate, thereby causing the material inside the tank 1 to rotate, allowing the material to be dried more evenly by hot air.

[0028] like Figure 2 , Figure 5 As shown, the end of the connecting cylinder 2 away from the tank 1 is closed. The central tube 4 passes through the interior of the connecting cylinder 2 and is connected to the outside. The end of the central tube 4 near the connecting cylinder 2 is connected to the hot air blower through a conduit. The outer wall of one end of the connecting cylinder 2 is rotatably connected to the interior of one end of the tank 1 through a bearing. A connecting pipe 201 is provided through the top of the connecting cylinder 2. A fixing plate 202 is fixedly connected to the outer wall of the connecting cylinder 2 away from the tank 1. When the hot air blower is started, hot air is delivered into the interior of the central tube 4, so that the hot air is delivered into the interior of the tank 1 away from the connecting cylinder 2 through the central tube 4. Then, it reaches the interior of the connecting cylinder 2 through the flow equalization plate 401 and the air permeable plate 6, and finally is discharged through the connecting pipe 201 at the top, realizing the circulation of hot air, which can effectively dry the material inside the tank 1 with hot air.

[0029] like Figure 5As shown, the outer wall of the vent plate 6 is in close contact with the inner wall of the tank body 1. A sleeve pipe 601 is fixedly connected to the center of the vent plate 6. The sleeve pipe 601 is sleeved with the outer wall of the central pipe 4. Flow equalization plates 401 are fixedly connected to both ends of the tank body 1. One end of the central pipe 4, near the inside of the tank body 1, passes through the interior of the two flow equalization plates 401. A fixing bolt 602 is threadedly connected to the outer wall of the sleeve pipe 601. One end of the fixing bolt 602 passes through the interior of the sleeve pipe 601 and is in close contact with the outer wall of the central pipe 4. Rotating the fixing bolt 602 releases the fixing of the sleeve pipe 601. Sliding the sleeve pipe 601 can effectively drive the vent plate 6 to move, thereby adjusting the interval between the vent plates 6. This changes the gap space between the two sides of the vent plate 6, allowing for effective adjustment according to the amount of material to be placed. At the same time, the interval of the vent plates 6 can effectively isolate the material on both sides of the vent plate 6, preventing material mixing.

[0030] In use, materials can be conveniently placed on both sides of different venting plates 6, and then the sealing plate 5 can be rotated to tightly seal it against the side wall of the tank 1. Then, the hot air blower is activated to deliver hot air into the central tube 4. The hot air is then transported through the central tube 4 to the end of the tank 1 furthest from the connecting cylinder 2, and then through the flow equalization plate 401 and venting plates 6 to reach the interior of the connecting cylinder 2. Finally, it is discharged through the top connecting pipe 201, achieving hot air circulation. This effectively dries the materials inside the tank 1 with hot air. During use, the drive assembly 3 can also be activated to drive the electric motor. The rotation of machine 303 drives the drive gear 302 to rotate, which in turn causes the drive gear 302 to rotate around the outer wall of the fixed gear ring 301. This, in turn, drives the drive motor 303 to rotate around the outer wall of the connecting cylinder 2, which in turn causes the tank 1 and the sealing plate 5 to rotate. This allows the material inside the tank 1 to rotate, enabling the material to be dried more evenly with hot air. At the same time, the flow equalization plate 401 also ensures that the airflow inside the tank 1 is more uniform, avoiding heat concentration and making the drying of the material inside the tank 1 more uniform. The continuous movement of the material effectively improves the drying efficiency.

[0031] When in use, for drying different materials, the fixing bolt 602 can be easily rotated first, thereby releasing the fixing of the sleeve 601. The sliding sleeve 601 can then effectively move the ventilator 6, thereby adjusting the spacing between the ventilator 6 and changing the gap space between the two sides of the ventilator 6. This allows for effective adjustment according to the amount of material to be placed. At the same time, the spacing of the ventilator 6 can also effectively isolate the material on both sides of the ventilator 6, preventing material mixing. This facilitates simultaneous hot circulation drying of multiple different materials, improving processing efficiency.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
