[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1 、 Figure 2 and Figure 3 , the utility model provides an embodiment: a tunnel kiln waste heat utilization device, including a kiln body 1, a collecting box 2 is fixedly connected to one side of the upper surface of the kiln body 1, a motor 3 is fixedly connected to the upper surface of the collecting box 2, a centrifugal fan blade 4 is fixedly connected to the output end of the motor 3, the centrifugal fan blade 4 is rotatably connected to the inside of the collecting box 2, a drying box 9 is fixedly connected to the adjacent side of the kiln body 1, a transmission shaft 5 is rotatably connected to the inside of the drying box 9, a gear 6 is fixedly connected to the outer wall of the transmission shaft 5, a belt 7 is transmission-connected between the transmission shaft 5 and the motor 3, a belt 7 is fixedly connected to the outer wall of the collecting box 2, a transmission air duct 8 is fixedly connected to the outer wall of the belt 7, and the transmission air duct 8 is fixedly connected to the upper surface of the drying box 9, and a storage assembly 10 for facilitating the removal of materials is installed on the inner wall of the drying box 9. A transmission pipe 12 is fixedly connected to the upper side of the inner wall of the drying box 9, and a rotating box 11 is rotatably connected to the outer wall of the transmission pipe 12. An external rack 14 is fixedly connected to the outer wall of the rotating box 11, and the external rack 14 is meshed with the gear 6. A plurality of air injection pipes 13 are fixedly connected to the lower surface of the rotating box 11; the storage assembly 10 includes a slide rail 1001, which is fixedly connected to the bottom of the inner wall of the drying box 9, a slider 1002 is slidably connected to the outer wall of the slide rail 1001, and a placement rack 1003 is fixedly connected to the upper surface of the slider 1002;

[0023] Specifically, by starting the motor 3, the centrifugal fan blades 4 quickly absorb the waste heat from the kiln body 1 and transport it to the interior of the drying box 9 through the transmission air duct 8. At the same time, the motor 3 drives the transmission shaft 5 in the belt 7 to rotate, causing the gear 6 to engage with the external rack 14, pushing the rotating box 11 and the air injection pipe 13 to rotate, ensuring that the drying box 9 is filled with hot air. This process effectively dries the wet material on the placement rack 1003 and quickly sets it into shape. After drying is completed, the slider 1002 on the placement rack 1003 is pulled and slid on the slide rail 1001, opening the sealed door on the outer wall of the drying box 9, making it convenient and quick to remove the dried material, thereby improving the operating convenience and work efficiency of the equipment.

[0024] Reference Figure 1 、 Figure 2 and Figure 3 , a processing box 15 is fixedly connected to the adjacent side of the drying box 9, and a filter box 16 is slidably connected to the inside of the processing box 15; a connecting pipe 17 is fixedly connected to the upper side of the inside of the processing box 15, and one end of the connecting pipe 17 is fixedly connected to the inside of the drying box 9; a water tank 23 is fixedly connected to the adjacent side of the processing box 15, and a pipe 18 is fixedly connected to the inside of the processing box 15, and the pipe 18 is fixedly connected to the inside of the water tank 23; one end of the pipe 18 is fixedly connected to the spiral tube 19, and one end of the spiral tube 19 is fixedly connected to the air outlet pipe 20; the air outlet pipe 20 is fixedly connected to the inside of the water tank 23, and one end of the air outlet pipe 20 is fixedly connected to the filter cartridge; the upper side of the inside of the water tank 23 is fixedly connected to the water inlet pipe 21, and the lower side of the inside of the water tank 23 is fixedly connected to the water outlet pipe 22;

[0025] Specifically, when the materials are dried and shaped, the residual heat will be transported to the connecting pipe 17 and then to the processing box 15 where it is carefully filtered by the filter box 16. Here, through a precise filtering process, the quality of the hot air is ensured to meet the highest standards. The filtered hot air is then transmitted to pipe 18 and then enters the spiral tube 19 to efficiently heat the cold water inside the water tank 23. This process not only ensures the stability of the water temperature and effective heating, but also maximizes energy utilization efficiency. After heating is completed, the hot water enters the carefully designed filter cartridge of the equipment through the outlet pipe 20 for secondary filtration to ensure that the hot air discharged into the atmosphere meets environmental standards. An intelligent switch valve is provided on the outer wall of the outlet pipe 20. This advanced design can accurately control the discharge volume and speed of the hot air, ensure environmental safety, and optimize the operating efficiency of the equipment.

[0026] Working principle: When in use, the centrifugal fan blades 4 are driven by starting the motor 3 to absorb the waste heat through the kiln body 1 and transmit it to the transmission duct 8 to the inside of the drying box 9, and then the waste heat is transmitted to the inside of the rotating box 11 through the transmission pipe 12. At the same time, the rotation of the motor 3 causes the transmission shaft 5 inside the belt 7 to rotate, and the transmission shaft 5 drives the gear 6 to engage and rotate with the external rack 14, thereby driving the rotating box 11 to drive the air injection pipe 13 to rotate, thereby filling the inside of the drying box 9 with hot air, so that the wet material on the placement rack 1003 is quickly shaped and dried. After the drying is completed, the placement rack 1003 is pulled to make the slider 1002 slide above the slide rail 1001, thereby opening the sealed door on the outer wall of the drying box 9 to achieve the effect of quickly taking out the material;

[0027] Secondly, after the material is dried and shaped, it is transmitted to the filter box 16 inside the processing box 15 through the connecting pipe 17 for filtration. At this time, the filtered hot air is transmitted to the inside of the pipe 18, and is transmitted to the cold water inside the heating tank 23 inside the spiral tube 19 through the pipe 18. After the heating is completed, it is filtered for the second time through the filter cartridge at one end of the outlet pipe 20 and then discharged into the atmosphere. A switch valve is installed on the outer wall of the outlet pipe 20 to realize the emission control of the hot air.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
