[0030] Please see Figure 1-4 This utility model provides a technical solution: a drying device for processing flame-retardant fabrics. It includes a drying box 1;

[0031] The drying oven 1 is equipped with a heat recovery device and two guiding components;

[0032] The heat recovery device includes a preheating box 13, a heat exchanger 7, and a suction tank 8. The suction tank 8 is fixedly connected to the upper surface of the drying box 1. The heat exchanger 7 is mounted on a mounting base on the upper surface of the drying box 1. One end of the suction tank 8 near the drying box 1 extends fixedly into the interior of the drying box 1. The preheating box 13 is fixedly connected to the upper surface of the drying box 1. The upper end of the suction tank 8 is fixedly connected to the outer wall of the heat exchanger 7 via a connecting pipe. The outer wall of the heat exchanger 7 is fixedly connected to one side of the outer wall of the preheating box 13 via a connecting pipe. A sliding seat 9 is slidably connected inside an arc-shaped groove on the lower outer wall of the suction tank 8. An activated carbon adsorption plate 15 is fixedly connected to the inner wall of the sliding seat 9. A first fan is installed inside the upper end of the suction tank 8. 16. The upper surfaces of the protrusions on both sides of the sliding seat 9 are threaded with fixing bolts 10. The upper surface of the drying box 1 has two fixing bolt slots 14. The ends of the two fixing bolts 10 near the fixing bolt slots 14 are threaded to the outside of the protrusions on both sides of the sliding seat 9 and are threaded to the inside of the corresponding fixing bolt slots 14. The upper surface of the preheating box 13 is fixedly connected with four air inlet pipes 12. The ends of the four air inlet pipes 12 near the preheating box 13 are fixedly extended into the interior of the preheating box 13. Two second fans 17 are installed inside the upper end of the preheating box 13. The interiors of the four air inlet pipes 12 are all connected to the interior of the preheating box 13. The interior of the preheating box 13 is connected to the interior of the drying box 1.

[0033] The guiding component includes two support frames 3 and two sliding blocks 2. The outer walls of the two support frames 3 are provided with sliding block grooves 11. The outer walls of the two sliding blocks 2 are respectively slidably connected to the inside of the sliding block grooves 11. The two support frames 3 are fixedly connected to the upper surface of the drying box 1. The inside of the drying box 1 is equipped with a conveying roller 18. The opposite surfaces of the two sliding blocks 2 are rotatably connected with guide rollers 4. The upper surfaces of the two support frames 3 are slidably connected with sliding rods 5. The ends of the two sliding rods 5 near the sliding blocks 2 are slidably extended into the sliding block grooves 11 and are respectively fixedly connected to the upper surface of the corresponding sliding blocks 2. Heating plates 19 are installed on the inner walls of both sides of the lower end of the drying box 1. The outer walls of the two sliding rods 5 are fitted with return springs 6. The two ends of the two return springs 6 are respectively fixedly connected to the upper surface of the corresponding sliding block 2 and the upper end of the sliding block groove 11.

[0034] Furthermore, when using this device, it is started by connecting to an external power source. First, the front guide roller 4 of the fabric is lowered, and the sliding block 2 is moved downward by the force exerted by the return spring 6, which drives the guide roller 4 downward, keeping it in constant contact with the fabric. Then, the fabric enters the interior of the drying chamber 1 through the feed inlet. Next, the heating plate 19 heats the interior of the drying chamber 1 while drying the fabric inside. Simultaneously, the fabric is conveyed to the discharge outlet of the drying chamber 1 by the conveying roller 18 inside the drying chamber 1. Then, the dried fabric is guided from the discharge outlet of the drying chamber 1 to the outside of the drying chamber 1 by the rear guide roller 4. At the same time, the first fan 16 blows the contents of the drying chamber 1... Hot air is drawn into the intake tank 8. After being treated by the activated carbon adsorption plate 15 inside the intake tank 8, the hot air is processed by the heat exchanger 7 and then enters the preheating box 13. Then, the second fan 17 draws outside air into the preheating box 13 through the air inlet pipe 12. The treated hot air then preheats the outside air entering the preheating box 13. The preheated outside air then enters the drying box 1 to assist in drying. This effectively utilizes excess heat energy. When it is necessary to remove the activated carbon adsorption plate 15, the fixing bolt 10 is turned so that its other end is disengaged from the inside of the fixing bolt groove 14. Then, the sliding seat 9 is pulled to remove the sliding seat 9 and the activated carbon adsorption plate 15 from the intake tank 8.

[0035] The first fan 16 in the heat recovery device draws hot air from inside the drying chamber 1 into the suction tank 8. After being treated by the activated carbon adsorption plate 15 inside the suction tank 8, the hot air is processed by the heat exchanger 7 and then enters the preheating chamber 13. Then, the second fan 17 draws outside air into the preheating chamber 13 through the air inlet pipe 12. The treated hot air then preheats the outside air entering the preheating chamber 13. The preheated outside air then enters the drying chamber 1 to assist in drying. This avoids energy waste, improves the practicality of the equipment, and reduces production costs. By turning the fixing bolt 10, its other end is disengaged from the inside of the fixing bolt groove 14. Then, the sliding seat 9 and the activated carbon adsorption plate 15 can be removed from the suction tank 8 by pulling the sliding seat 9. This facilitates the maintenance and repair of the activated carbon adsorption plate 15, effectively extends the service life of the activated carbon adsorption plate 15, and improves the flexibility of the equipment.

[0036] Working principle: First, the fabric is guided downwards by the front guide roller 4. Simultaneously, the force exerted by the return spring 6 on the sliding block 2 causes the sliding block 2 to move downwards, driving the guide roller 4 downwards while maintaining constant contact with the fabric. Then, the fabric enters the drying chamber 1 through the upper inlet. Next, the heating plate 19 heats the interior of the drying chamber 1, drying the fabric inside. Simultaneously, the fabric is conveyed to the drying chamber 1 outlet by the conveyor roller 18 inside the drying chamber 1. After drying, the fabric is guided out of the drying chamber 1 through the rear guide roller 4. At the same time, the first fan 16 draws hot air from inside the drying chamber 1 into the suction tank 8. Inside, hot air is treated by the activated carbon adsorption plate 15 inside the intake tank 8, then processed by the heat exchanger 7 before entering the preheating box 13. Then, the second fan 17 draws outside air into the preheating box 13 through the air inlet pipe 12. The treated hot air then preheats the outside air entering the preheating box 13. The preheated outside air then enters the drying box 1 to assist in drying, thus effectively utilizing excess heat energy. When it is necessary to remove the activated carbon adsorption plate 15, the fixing bolt 10 is turned so that its other end is disengaged from the inside of the fixing bolt groove 14. Then, the sliding seat 9 is pulled to remove the sliding seat 9 and the activated carbon adsorption plate 15 from the intake tank 8.

[0037] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
