[0031] In this embodiment, when the hot air dryer body 1 is in operation, the outside air enters the air inlet pipe 2, and then the dust and other particulate impurities are intercepted by the filter 3. The filtered air enters the hot air dryer body 1 for drying. The hot air dryer body 1 is a prior art, and its working principle is not described here. The dust and other particulate impurities intercepted by the filter 3 will be discharged from the drain port 10 under the action of gravity. When the filter 3 needs to be cleaned, the motor 7 is started, the motor 7 drives the gear 6 to rotate, the gear 6 drives the gear ring 5 to rotate, and the gear ring 5 The two spiral scrapers 8 are driven to rotate, and the spiral scrapers 8 are in contact with the inside of the air inlet pipe 2. As the spiral scrapers 8 rotate, the dust adhering to the inside of the air inlet pipe 2 is scraped off and falls to the bottom of the air inlet pipe 2. Since the spiral scrapers 8 are spiral-shaped, the rotation of the spiral scrapers 8 below will push dust and other particulate impurities to the sewage outlet 10 and discharge them from the sewage outlet 10. When the spiral scrapers 8 rotate, the rotating scraper 9 is driven to rotate, so that the rotating scraper 9 scrapes and cleans the filter 3, and the cleaned dust and impurities will also be discharged from the sewage outlet 10.

[0032] More specifically, the motor 7 can be started to make the spiral scraper 8 scrape and clean the inside of the air inlet pipe 2, and the rotating scraper 9 scrapes and cleans the filter 3. When the filter 3 needs to be replaced, a handle is provided on the mounting plate 12. When the handle is pulled, the mounting plate 12 is driven to move, and the mounting plate 12 drives the mounting ring 11 and the filter 3 to move out of the mounting groove 13, so as to remove it.

[0033] See also Figure 1-5As an implementation method for replacing the filter 3: the outer side of the air inlet pipe 2 is recessed inward to form three fixed chambers 14, and a movable plate 15 is movably provided in each of the fixed chambers 14, and a spring 16 is fixedly connected between one side of each movable plate 15 and the fixed chamber 14, and a plug rod 17 is fixedly provided on one side of the movable plate 15, and three sockets 18 matching the plug rod 17 are provided on one side of the mounting plate 12, and the upper ends of the three movable plates 15 pass through the fixed chamber 14 and are fixedly connected to a push plate 19.

[0034] Specifically, push the push plate 19, which drives the three movable plates 15 to move simultaneously, compress the spring 16, and drive the movable plate 15 to move the plug rod 17, so that the plug rod 17 is removed from the socket 18. Pull the handle, which drives the mounting plate 12, the mounting ring 11 and the filter screen 3 to move, so that they are moved out of the mounting groove 13, thereby removing them, and the cleaned or replaced filter screen 3 can be installed using the opposite operation.

[0035] See also Figure 1-5 As an implementation method for disassembling the collection box 20: the collection box 20 is movably provided at the lower end of the air inlet pipe 2, and a limiting groove 21 matching the collection box 20 is provided at the lower end of the air inlet pipe 2. A bracket 22 is fixedly provided at the lower end of the air inlet pipe 2, and a screw 23 is threadedly connected to the bracket 22. The upper end of the screw 23 passes through the bracket 22 and is rotatably connected to a fixing plate 24 that is slidably connected to the bracket 22 through a track.

[0036] Specifically, dust and other particulate impurities discharged from the sewage outlet 10 will fall into the collection box 20 for collection. When the collection box 20 needs to be disassembled for cleaning, the screw 23 is rotated. The screw 23 moves away from the collection box 20 while rotating. The screw 23 drives the fixed plate 24 to move downward along the sliding connection with the bracket 22. Under the action of gravity, the collection box 20 moves downward with the fixed plate 24 and moves out of the limit groove 21, thereby disassembling the collection box 20. The cleaned collection box 20 can be installed using the opposite operation.

[0037] To sum up, when the overall equipment is in use:

[0038] When the hot air dryer body 1 is in operation, the outside air enters the air inlet pipe 2, and then passes through the filter 3 to intercept dust and other particulate impurities. The filtered air enters the hot air dryer body 1 for drying. The hot air dryer body 1 is a prior art, and its working principle is not described here. The dust and other particulate impurities intercepted by the filter 3 will be discharged from the drain port 10 under the action of gravity. When the filter 3 needs to be cleaned, the motor 7 is started, the motor 7 drives the gear 6 to rotate, the gear 6 drives the gear ring 5 to rotate, and the gear ring 5 drives The two spiral scrapers 8 are driven to rotate, and the spiral scrapers 8 are in contact with the inside of the air inlet pipe 2. As the spiral scrapers 8 rotate, the dust adhering to the inside of the air inlet pipe 2 is scraped off and falls to the bottom of the air inlet pipe 2. Since the spiral scrapers 8 are spiral-shaped, the rotation of the spiral scrapers 8 below will push dust and other particulate impurities to the sewage outlet 10 and discharge them from the sewage outlet 10. The rotation of the spiral scrapers 8 will drive the rotating scraper 9 to rotate, so that the rotating scraper 9 scrapes and cleans the filter screen 3, and the cleaned dust and impurities will also be discharged from the sewage outlet 10.

When the collection box 20 needs to be disassembled for cleaning, the screw 23 is rotated. The screw 23 will move away from the collection box 20 while rotating. The screw 23 drives the fixed plate 24 to move downward along the sliding connection with the bracket 22. Under the action of gravity, the collection box 20 moves downward with the fixed plate 24 and moves out of the limit slot 21, thereby disassembling the collection box 20. The cleaned collection box 20 can be installed using the opposite operation.

[0040] When the filter 3 needs to be disassembled, cleaned or replaced, the push plate 19 is pushed, and the push plate 19 drives the three movable plates 15 to move at the same time. The spring 16 is compressed, and the movable plate 15 drives the insertion rod 17 to move, so that the insertion rod 17 is removed from the insertion hole 18. A handle is provided on the mounting plate 12. When the handle is pulled, the mounting plate 12, the mounting ring 11 and the filter 3 are driven to move, so that they are moved out of the mounting groove 13, thereby removing them. The cleaned or replaced filter 3 can be installed using the opposite operation.
