[0038] The suction pipe 202 and the air inlet pipe 203 are formed in reverse order along the C-type heat exchange tube 201 in a horizontal direction inside the C-type heat exchange tube 201. The bottom port of the suction pipe 202 is connected to the bottom port of the C-type heat exchange tube 201, and the bottom port of the air inlet pipe 203 extends through to the side of the C-type heat exchange tube 201 away from the frame body 101.

[0039] The connecting horizontal pipe 204 is fixed to the top side of the C-type heat exchange tube 201. The top ports of multiple air inlet pipes 203 are connected to the connecting horizontal pipe 204. The input end of the upper fan 105 is connected to the connecting horizontal pipe 204.

[0040] The hot air containing water vapor inside the drying oven 102 is drawn into the suction pipe 202. The upper fan 105 draws outside air through the air inlet pipe 203. The hot air containing water vapor inside the suction pipe 202 is used to heat the air in the air inlet pipe 203.

[0041] The preheating unit includes a preheating fan 205;

[0042] The preheating fan 205 is fixed to the top of the drying oven 102. The input end of the preheating fan 205 is connected to the top end of the C-type heat exchange tube 201, and the top ports of multiple suction pipes 202 are connected to the input end of the preheating fan 205.

[0046] The collection box 206 is used to collect water droplets condensed on the inner wall of the suction pipe 202, and the drain pipe 207 is used to drain the condensate.

[0047] In this embodiment, it should be noted that the driving structure of the Teflon mesh belt 103 is an existing conveyor belt structure, which has been widely used in the field of conveying and drying, so it will not be described in detail here.

[0048] The operating principle for drying textiles is as follows:

[0049] First, the infrared heating tube 104 is activated, which heats the inside of the drying chamber. When the temperature reaches the set temperature, the drive structure of the Teflon mesh belt 103 is activated to make the Teflon mesh belt 103 run.

[0050] Next, the textile to be dried is placed at the front end of the Teflon mesh belt 103, and the upper fan 105 and the preheating fan 205 are started simultaneously. At this time, the preheating fan 205 can draw the hot air inside the drying chamber into the preheating chamber through the suction pipe 202, while the upper fan 105 draws the outside air into the drying chamber through the channel formed by the air inlet pipe 203 and the connecting horizontal pipe 204 for heating. The hot air inside the suction pipe 202 exchanges heat with the air inside the air inlet pipe 203 to heat the air. The heated air can be heated to the specified temperature more quickly by the infrared heating tube 104 when it enters the drying chamber.

[0051] When the textile is preheated inside the preheating chamber, it is then transported to the drying chamber for further heating. During this process, the water vapor generated by the heating is drawn into the suction pipe 202 along with the hot air. When the hot air heats the air inside the air inlet pipe 203, the water vapor condenses on the inner wall surface of the suction pipe 202 and then slowly gathers inside the collection box 206. When there is a lot of condensate inside the collection box 206, the drain pipe 207 can be opened to collect and discharge the condensate.

[0052] By repeating the above steps, waste heat from the steam-containing gas can be recovered, further improving energy utilization efficiency.

[0053] Please refer to this carefully. Figures 1-3 The air dryer assembly 1 also includes a C-shaped duct 106 and a downdraft fan 107;

[0054] C-shaped pipe 106 is fixed to the side of the frame body 101 and the drying box 102 away from the C-shaped heat exchange tube 201. The upper and lower ports of the C-shaped pipe 106 are respectively connected to the inner cavity of the drying box 102 and the frame body 101, and the top port of the C-shaped pipe 106 is located below the infrared heating tube 104.

[0055] The down fan 107 is fixed inside the frame body 101 and distributed inside the transmission track of the Teflon mesh belt 103. The input end of the down fan 107 is connected to the bottom port of the C-shaped pipe 106, and the output end of the down fan 107 faces upward and is aligned with the Teflon mesh belt 103.

[0056] Multiple upper fans 105 and lower fans 107 are arranged along the long side of the frame body 101 and the drying box 102, and the multiple upper fans 105 and lower fans 107 are staggered along the long side, and the multiple upper fans 105 and lower fans 107 are also staggered along the short side of the frame body 101 and the drying box 102.

[0057] In this embodiment: while the upper fan 105 is running, the lower fan 107 is running synchronously. The lower fan 107 can draw the air heated by the infrared heating tube 104 into the inner side of the frame body 101 and blow it onto the lower surface of the Teflon mesh belt 103, thereby realizing the drying operation of the lower surface of the textile.

[0058] By distributing multiple upper fans 105 and lower fans 107 in a staggered manner along the long and short sides, all-round air-drying coverage of textiles can be achieved.

[0059] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
