[0043] The power mechanism is connected to the chain 14 and is used to drive the wet firewood frame 7 to move.

[0044] With the above structure: After the flue gas inside the firewood kiln main body 1 is injected into the treatment box 5, the heat in the flue gas can heat-treat the wet firewood. At the same time, the stacked firewood has a certain adsorption function and can purify the flue gas. And through the transmission of the structure, the wet firewood frame 7 can be driven in and out of the treatment box 5, which is convenient for replacing the materials inside the wet firewood frame 7.

[0045] Please refer to Figure 2 , the power mechanism includes a power motor 10, a worm 11, a worm gear 12 and a main sprocket 13. The output end of the power motor 10 is key-connected to the bottom end of the worm 11. The surface of the worm 11 meshes with the right side of the worm gear 12. The rear side of the worm gear 12 is key-connected to the surface of the main sprocket 13. The main sprocket 13 meshes with the chain 14. When the power supply of the power motor 10 is turned on, the power motor 10 is controlled by a motor controller.

The partition 18 can abut against the treatment box 5, which can prevent flue gas from overflowing upward through the partition 18.

[0050] Embodiment 2

[0051] The difference between this embodiment and Embodiment 1 is that the power motor 10, the worm 11 and the worm gear 12 are replaced by a heat-resistant motor. The heat-resistant motor can directly drive the main sprocket 13 to rotate. However, the heat-resistant motor also needs to be equipped with a self-locking structure and its cost is relatively high. Therefore, the power motor 10, the worm 11 and the worm gear 12 are preferably used in this application.

[0052] It should be noted that: the specific models of the exhaust fan 2 and the power motor 10 are selected by those skilled in the relevant art. The above about the exhaust fan 2 and the power motor 10 and the like all belong to the prior art and will not be elaborated in this solution.

[0053] The main body 1 of the firewood kiln adopts the prior art and can adopt the main body structure of the patent with the application number 201721697997.6.

[0054] The working principle of the present utility model: Before adding materials to the main body 1 of the firewood kiln for heating, the power supply of the power motor 10 is turned on. The power motor 10 is controlled by a motor controller. The power motor 10 can drive the worm 11 to rotate. The worm 11 can drive the worm gear 12 to rotate. The worm gear 12 can drive the main sprocket 13 to rotate counterclockwise. The main sprocket 13 can drive the chain 14 to rotate counterclockwise. The chain 14 can drive the secondary sprocket 15 to rotate counterclockwise. The secondary sprocket 15 is arranged on the treatment box 5 through a bearing. The chain 14 can drive the wet firewood frame 7 to move to the left. After the wet firewood frame 7 is moved out of the treatment box 5, various firewoods to be processed can be stacked inside the wet firewood frame 7, and then the movable baffle 9 is used to block. After the wet firewood frame 7 is full, the power mechanism moves the wet firewood frame 7 into the treatment box 5. When smoke needs to be exhausted during the heating process of the main body 1 of the firewood kiln, the power supply of the exhaust fan 2 is turned on. The exhaust fan 2 can input the flue gas into the inside of the gas transmission pipe 3. The gas transmission pipe 3 can inject the flue gas into the treatment box 5 through the connecting pipe 4. The flue gas enters the inside of the wet firewood frame 7 through the pore plate 8 of the wet firewood frame 7. The firewood can absorb heat and purify the flue gas, and there is no need to carbonize the firewood in the future.

[0055] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
