[0040] The working principle of the above technical solution is as follows:

[0041] When using this kiln, wood is placed on the support plate 21 for charcoal burning. The support plate 21 is set up at the combustion port 22. After the charcoal is burned, lifting the hydraulic rod 50 opens the furnace lid. Continuing to lift will raise the furnace lid and support plate 21 together to the outside of the furnace. At this time, the bolts can be loosened, and the extension frame 60 can be rotated relative to the hydraulic rod 50. After rotating to a position where it is convenient to remove the charcoal, the staff can use tools to quickly remove the charcoal from the support plate 21. After the above steps are completed, the kiln is restored. Before charcoal burning, the second exhaust pipe 34 is placed on the support member 40, and the first connecting hose 33 is bent up and down. The tilt angle of the second exhaust pipe 34 is adjusted, and the second connecting hose 35 is aligned at any angle. The flange at the end of the second connecting hose 35 is aligned with the flange of the flue gas treatment equipment for connection. The flexible and adjustable exhaust pipe assembly facilitates quick connection to the flue gas treatment equipment. The equipment; in addition, the first connecting hose 33 and the second connecting hose 35 can significantly reduce the vibration transmitted by the cover 30 and the exhaust pipe 31, avoiding affecting the stability of the equipment for treating flue gas. The aforementioned support member 40 provides stable support for the second exhaust pipe 34, further reducing the vibration transmitted by the second exhaust pipe 34. Moreover, the rotatable internal threaded cylinder 43 can be raised and lowered relative to the screw 42 to achieve fine adjustment of the height of the second exhaust pipe 34, meeting the dynamically changing connection conditions. The air intake device has an installation pipe 72 on one side of the air intake pipe 71. Taking advantage of the elastic and freely bendable transmission characteristics of the flexible shaft 73, the flexible shaft 73 is bent and extended from the installation pipe 72 into the air intake pipe 71. When it is necessary to clean the air intake pipe 71, the first sealing cover is opened, and the flexible shaft 73 can be rotated or extended. The scraping block 75 at the end of the flexible shaft 73 repeatedly scrapes and removes impurities from the inner wall of the installation pipe 72 to achieve the cleaning effect.

[0042] In another embodiment, such as Figure 9As shown, a groove is provided in the middle of the bottom wall of the combustion chamber, and a carrier box 15 is provided in the groove. The bottom wall of the combustion chamber is an inclined surface that slopes downward along the direction close to the groove. The inlet and outlet 13 are connected to the groove. The carrier box 15 is a square box with an open top. Support rods 16 for carrying fuel are provided at intervals at the top opening of the carrier box 15. A discharge port is provided at the bottom of the carrier box 15 on the side close to the inlet and outlet 13. Several protrusions 17 are evenly spaced on the inclined surface of the bottom wall of the combustion chamber.

[0043] The carrier box 15 can be removed and placed separately from the groove. The support rods 16 on the carrier box 15 can jointly support the solid fuel with the inclined surface at the bottom of the furnace. The residue after the solid fuel is burned can fall into the carrier box 15 through the gaps between the support rods 16. The inclined surface of the bottom wall of the combustion chamber is conducive to the concentrated falling of the residue into the carrier box 15. When it is necessary to clean the residue, the carrier box 15 can be pulled out from the inlet 13 so that the bottom of the discharge port is no longer blocked, and most of the residue in the combustion chamber can be easily discharged, ensuring that there is enough space in the combustion chamber, saving time and effort. The protrusions 17 are used to support the solid fuel, which is conducive to the even distribution of the solid fuel on the inclined surface of the furnace. The residue produced after combustion can fall smoothly into the carrier box 15 along the inclined surface through the gaps between the protrusions 17.

[0044] In another embodiment, such as Figure 6 and Figure 8 As shown, the inner wall of the end of the mounting tube 72 away from the air intake tube 71 is provided with a groove in the circumference, and the edge of the baffle 74 is engaged with the groove; the side of the limiting block 76 away from the flexible shaft 73 is provided with a handle 77 that extends out of the mounting tube 72; a drain pipe 78 is provided on the bottom side of the air intake tube 71 near the input end, and a drain valve is provided on the drain pipe 78; a sludge discharge pipe 79 is provided on the bottom side of the air intake tube 71 near the output end, and a sealing cap is provided at the end of the sludge discharge pipe 79.

[0045] The baffle 74 can be removed from the mounting tube 72. After long-term use of the scraping assembly, the entire scraping assembly can be disassembled for replacement or cleaning. The handle 77 can be installed on the limit block 76 during cleaning and disassembled after cleaning for easier use. The drain pipe 78 can temporarily store and discharge some of the condensed water in the gas, and the impurity removal pipe can temporarily store and discharge the impurities scraped off the exhaust pipe.

[0046] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
