[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] like Figure 1-5 As shown, a waste heat utilization type carbonization kiln includes a kiln chamber 1. A bottom plate 2 is fixedly connected to the inner bottom wall of the kiln chamber 1. A groove 3 is formed on the upper surface of the bottom plate 2. A slider 4 is slidably connected inside the groove 3. A placement plate 5 is fixedly connected to the upper surface of the slider 4. A baffle 6 is fixedly connected to the outer surface of the placement plate 5. A ventilation pipe 7 is fixedly connected to the upper surface of the kiln chamber 1. A first gear 8 is rotatably connected to the inner side wall of the ventilation pipe 7. A turbine rod 9 is fixedly connected to the outer surface of the first gear 8. A blade 10 is fixedly connected to the outer surface of the turbine rod 9. The turbine rod 9 is rotatably connected to the ventilation pipe 7. A second gear 11 is meshed with the outer surface of the first gear 8. The second gear 11 is rotatably connected to the ventilation pipe 7. A fixing rod 12 is fixedly connected to the outer surface of the ventilation pipe 7. A generator 13 is fixedly connected to the top end of the fixing rod 12. The input end of the generator 13 is fixedly connected to the second gear 11.

[0025] In practical use, when the staff is loading or unloading materials, they pull open the second handle 31 to slide out the placement plate 5, which allows for loading or unloading in one go. This not only reduces the risk of staff being burned by residual heat when changing or loading materials directly in the kiln chamber 1, but also improves the staff's work efficiency. When the combustion chamber 24 starts to burn, the high-temperature and high-pressure gas generated in the kiln chamber 1 drives the blades 10 to rotate. This causes the first gear 8 to mesh and drive the second gear 11 to rotate. The second gear 11 drives the generator 13 to rotate, converting kinetic energy into electrical energy. The kinetic energy of the rotating blades 10 indirectly drives the fan blades 20 to rotate, realizing the automatic air supply function of the device to the combustion chamber 24. This not only makes the maximum use of the waste gas in the kiln, but also saves labor resources.

[0026] In this embodiment, a first belt 14 overlaps the outer surface of the turbine rod 9, a support plate 15 is fixedly connected to the upper surface of the kiln chamber 1, a bearing 16 is rotatably connected to the axis of the support plate 15, a first rotating rod 17 is fixedly connected to the axis of the bearing 16, the first rotating rod 17 overlaps with the first belt 14, a second belt 18 overlaps the outer surface of the first rotating rod 17, a second rotating rod 19 overlaps the inner side of the second belt 18, a fan blade 20 is fixedly connected to the outer surface of the second rotating rod 19, a housing 21 is rotatably connected to the second rotating rod 19, an air supply pipe 22 is fixedly connected to the outer surface of the housing 21, and an air inlet 23 is opened on the outer surface of the housing 21.

[0027] In practical use, through the arrangement of the first belt 14, support plate 15, first rotating rod 17, second belt 18, second rotating rod 19, fan blades 20, air supply pipe 22 and air inlet 23, when the high-temperature and high-pressure gas generated in the kiln chamber 1 rises, it drives the blades 10 to rotate. The blades 10 drive the turbine rod 9 to rotate. The turbine rod 9 indirectly drives the second rotating rod 19 to rotate through the first belt 14 and the first rotating rod 17. The second rotating rod 19 drives the fan blades 20 to rotate. This can realize the delivery of natural air from the air inlet 23 to the air supply pipe 22, saving manpower.

[0028] In this embodiment, a combustion chamber 24 is fixedly connected to the lower surface of the kiln chamber 1, and an air supply pipe 22 is fixedly connected to the combustion chamber 24.

[0029] In practical use, through the arrangement of the air supply pipe 22, fan blades 20 and air inlet 23, natural air is brought into the combustion chamber 24 through the air inlet 23 by the fan blades 20 and into the air supply pipe 22, which can realize the automatic air supply of the device to assist the combustion of fuel in the combustion chamber 24.

[0030] In this embodiment, a hinge 25 is fixedly connected to the outer surface of the combustion chamber 24, a stove opening plate 26 is fixedly connected to the outer surface of the hinge 25, and a first handle 27 is fixedly connected to the outer surface of the stove opening plate 26.

[0031] In practical use, thanks to the hinge 25, the burner plate 26, and the first handle 27, the operator can use the first handle 27 to open the burner plate 26 to add fuel and then close the burner plate 26, preventing sparks from splashing out and reducing the possibility of safety hazards.

[0032] In this embodiment, a filter tube 28 is fixedly connected to the upper surface of the ventilation duct 7.

[0033] In practical use, through the setting of filter tube 28, the fine impurities generated by the raw materials during the carbonization process will rise with the high temperature and high pressure gas in the furnace. The filter tube 28 is equipped with a filter screen, which can effectively filter out the impurities and prevent the impurities from accumulating in the air supply pipe 29 and causing blockage.

[0034] In this embodiment, an air supply pipe 29 is fixedly connected to the upper surface of the filter pipe 28, and the output end of the air supply pipe 29 is fixedly connected to the combustion chamber 24.

[0035] In practical use, the air supply pipe 29 is set up so that one end of the air supply pipe 29 is fixedly connected to the filter pipe 28 and the other end is fixedly connected to the combustion chamber 24, so that the high temperature and high pressure gas generated in the kiln chamber 1 can directly reach the combustion chamber 24 through the air supply pipe 29 to perform secondary combustion of the raw materials, thus saving fuel resources.

[0036] In this embodiment, a telescopic rod 30 is fixedly connected to the outer surface of the baffle 6, and the output end of the telescopic rod 30 is fixedly connected to the kiln chamber 1.

[0037] In practical use, the telescopic rod 30 is extended when the worker pulls out the placement plate 5 through the second handle 31 while loading materials, which makes the worker more balanced during the loading and unloading process.

[0038] In this embodiment, a second handle 31 is fixedly connected to the outer surface of the baffle 6.

[0039] In practical use, the second handle 31 is fixedly connected to the baffle 6. The staff can pull out the placement plate 5 through the second handle 31 to achieve one-time loading and prevent the staff from being burned during the loading and unloading process.

[0040] Working principle: During use, when loading or unloading materials, the operator pulls the second handle 31 to slide out the placement plate 5, placing the material to be carbonized into the kiln chamber 1. Loading or unloading can be done in one go. The operator can use the first handle 27 to open the burner plate 26 to replenish fuel and then close the burner plate 26 to prevent sparks from splashing out. When combustion begins in the combustion chamber 24, the high-temperature, high-pressure gas generated in the kiln chamber 1 drives the blades 10 to rotate. This causes the first gear 8 to mesh and drive the second gear 11 to rotate, which in turn drives the generator 13 to rotate, converting kinetic energy into electrical energy. 10 drives the turbine rod 9 to rotate. The turbine rod 9 indirectly drives the second rotating rod 19 to rotate through the first belt 14 and the first rotating rod 17. The second rotating rod 19 drives the fan blades 20 to rotate, which can realize the delivery of natural air from the air inlet 23 to the air supply pipe 22. One end of the air supply pipe 29 is fixedly connected to the filter pipe 28, and the other end is fixedly connected to the combustion chamber 24. This allows the high-temperature and high-pressure gas generated in the kiln chamber 1 to directly reach the combustion chamber 24 through the air supply pipe 29 to perform secondary combustion of the raw materials. This not only maximizes the utilization of the waste gas in the kiln, but also saves labor resources.
