[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] In the process of processing thermal film, long-distance drying is required. This is due to the production characteristics of thermal film. Long-distance drying often only has a drying effect at one end, and the other part of the heat will be wasted when it flows back to the origin after use, which will increase energy consumption and waste. Figure 1-3 This scheme designs a thermal film drying unit, including a heating box 1, a drying tube 2, a heating wire 3, and a heating liquid 4. The drying tube 2 is provided with multiple groups for outputting the heated heat for heating the space and then performing the drying operation.

[0021] Specifically: because heat will be wasted during traditional water return, a return pipe 5 is sheathed inside the drying pipe 2. The return pipe 5 is wrapped by installing it inside the drying pipe 2. The return pipe 5 is fixed in the drying pipe 2 through a fixing part. The return pipe 5 and the drying pipe 2 have the same length and shape. At the same time, the return pipe 5 is arranged at the center of the drying pipe 2 and is arranged parallel to it to prevent mutual contact. The water inlet end of the return pipe 5 is connected to the drying pipe 2, and the drying pipe 2 is connected to the heating box 1. Therefore, the drying pipe 2 outputs the heat in the heating box 1, and the return pipe 5 recovers this part of the heat and outputs it to the drying pipe 2 to generate heat.

[0022] A partition 6 is provided inside the heating box 1 to divide the heating box 1 into two parts. The heating wire 3 is fixed in the heating box 1 and arranged in one of the parts. The return pipe 5 is arranged through the partition 6 and is connected to one of the parts. The drying pipe 2 is connected to one side of the heating box 1, and the return pipe 5 is connected to the other side of the heating box 1. Therefore, through the heating box 1, the drying pipe 2 can form a circulation with the return pipe 5. At the same time, a plurality of return holes 7 are provided on the partition 6 for normal and smooth circulation. The heating liquid 4 is filled in the drying pipe 2 and the heating box 1 to act as a heating medium for outputting heat.

[0023] The return pipe 5 and the drying pipe 2 are separated at the end. After separation, the end of the return pipe 5 is exposed, so that the heating liquid 4 reaches the end in the drying pipe 2, enters the return pipe 5 through the end of the return pipe 5, and circulates into the heating box 1.

[0024] In order to accelerate and guide the circulation of the heating liquid 4, a motor 8 is fixedly connected to the inside of the drying tube 2 away from the end of the heating box 1, and a rotating shaft 9 is fixedly connected to the motor 8. The rotating shaft 9 extends into the return pipe 5 and is fixedly connected to a propulsion blade 10. A plurality of connecting rods 11 are fixedly connected to the rotating shaft 9. The plurality of connecting rods 11 form a circle. The circle formed by the plurality of connecting rods 11 is arranged around the drying tube 2. A suction blade 12 is fixedly connected to each connecting rod 11. The curvature of the suction blade 12 and the propulsion blade 10 are opposite. Therefore, while the propulsion blade 10 and the suction blade 12 are driven to rotate by the motor 8, suction and propulsion are performed synchronously, so that the circulation efficiency of the entire heating liquid is improved and an effective circulation operation can be smoothly formed. The return pipe 5 and the drying tube 2 are nested with each other so that the heating liquid 4 in the return pipe 5 can be wrapped by the drying tube 2 during the reflux process, so that the temperature lost after the reflux is minimized, thereby achieving the effect of reducing the drying output energy consumption.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
