[0056] In this embodiment, the power mechanism includes a vertical shaft assembly 15 fixed to the lower end of the output shaft of the motor assembly 14. The vertical shaft assembly 15 passes through the flue gas conveying assembly and extends into the flue gas conveying assembly. A double bevel gear meshing assembly 23 is installed at one end of the vertical shaft assembly 15 located in the flue gas conveying assembly. The double bevel gear meshing assembly 23 is connected to the power shaft 24.

[0057] A linkage belt assembly 13 is installed between the vertical shaft assembly 15, the spiral lifting component 30, and the second fan blade assembly 27. The linkage belt assembly 13 can be a belt structure or a sprocket structure, selected according to actual conditions to ensure practicality. Among the three linkage wheels / sprockets in the linkage belt assembly 13, the middle linkage wheel / sprocket is set to be larger, or the middle linkage wheel / sprocket is not on the same straight line as the other two linkage wheels / sprockets, so as to fully realize the connection with the belt or chain and ensure the stable transmission of power. Its setting is optimized according to the structure to ensure stable power transmission and ensure that the vertical shaft assembly 15, the second fan blade assembly 27, and the spiral lifting component 30 can rotate.

[0058] The double bevel gear meshing assembly consists of two meshing bevel gears that can transmit power, facilitating the rotation of the first fan blade assembly. A corresponding gas outlet is opened at the upper end of the flue gas conveying assembly, allowing the gas to enter the space set by the inclined member, facilitating the directional flow of the gas, thereby driving the gas flow within the flue gas conveying assembly. This allows the flue gas generated by the combustion assembly to enter the flue gas conveying assembly and be discharged through the lower end of the inclined member.

[0059] In this embodiment, the driving mechanism includes a reverse gear transmission assembly 43 installed at the lower end of the scraper 35. The reverse gear transmission assembly 43 and the spiral lifting member 30 are connected to one end extending from the lower end of the scraper 35. A diagonal rod 38 is rotatably sleeved at the bottom of the scraper 35. An abutment transmission assembly 39 is installed between the diagonal rod 38 and the spiral lifting member 30.

[0060] The lower end of the wire brush component 41 is rotatably sleeved inside the bottom of the scraper component 35. A chain linkage assembly 40 is installed between the wire brush component 41 and the inclined rod component 38. The reverse gear transmission assembly 43 includes two meshing gears and an internal gear ring component. The internal gear ring component is fixedly connected to the scraper component 35. The spiral lifting component 30 can drive one gear component to rotate, which in turn drives the other gear component to rotate. The other gear is rotatably connected to the lower end of the scraper component 35, and it can drive the internal gear ring to rotate, thus causing the scraper component 35 to rotate. In actual operation, the rotation speed of the scraper component 35 can be adjusted by controlling the specifications of the two gears, so that the spiral lifting component 30 and the scraper component 35 can rotate in opposite directions. The rotation of the scraper component 35 causes the side on which the wire brush component 41 is installed to rotate around the inner wall of the conical filter screen 34. The rotation of the wire brush component 41 allows impurities attached to the conical filter screen 34 to enter the scraper component 35, so that the impurities can be driven upward by the spiral lifting component 30.

[0061] The contact transmission assembly 39 consists of two meshing bevel gears or two contact transmission bevel wheels, so that the inclined rod 38 can be rotated through the spiral lifting member 30 and the contact transmission assembly 39, and at the same time, the wire brush member 41 can be rotated through the chain linkage assembly 40. The rotation of the wire brush member 41 can sweep the impurities on the conical filter screen 34 into the scraper member 35.

[0062] In this embodiment, the diversion and cooling mechanism includes a second conical partition plate 37 fixed to the bottom of the inner tube 29. A connecting frame 26 is sealed between the second conical partition plate 37 and the tube 29. Multiple bent conveying pipes 32 are evenly spaced through the first conical partition plate 36. The upper end of the bent conveying pipe 32 is inserted through the tube 29, and the lower end of the tube 29 is inserted through a return pipe 33. One end of the return pipe 33 is inserted through the lower end of the flue gas conveying assembly. After the gas enters the conical filter screen 34, impurities are retained on the inner wall of the conical filter screen 34. The gas can enter between the conical filter screen 34 and the first conical partition plate 36, and can enter the cavity formed by the tube 29, the first conical partition plate 36, and the second conical partition plate 37 through the bent conveying pipes 32. Heat exchange can be performed between the bent conveying pipes 32 and the heat exchange medium, reducing the temperature of the gas in the bent conveying pipes 32, and the gas can be discharged through the bent conveying pipes 32.

[0063] In this embodiment, the dust extraction and suction mechanism includes a reverse gear transmission assembly 43 inclinedly disposed through one side of the upper end of the conveying pipe 31. One end of the negative pressure pipe 42 is disposed through the reverse gear transmission assembly 43. A filter screen is installed at the connection between the reverse gear transmission assembly 43 and the negative pressure pipe 42. The negative pressure pipe 42 allows gas to flow, and the filter screen can block impurities. One end of the reverse gear transmission assembly 43 can be connected to an external collection assembly for easy collection of impurities. At the same time, the suction effect of the negative pressure pipe 42 allows gas to enter the reverse gear transmission assembly 43 from the scraper 35 through the conveying pipe 31, so that the impurities can rise in conjunction with the spiral lifting member 30 and remain in the reverse gear transmission assembly 43, which facilitates the centralized collection of impurities.

[0064] In this invention, combustion in the incineration assembly 1 causes the flue gas to rise, which can filter impurities through the conical filter screen 34 and allow the flue gas to enter the bent conveying pipe 32 to exchange heat with the cooling medium. At the same time, the wire brush 41 can clean the impurities on the conical filter screen 34 and allow them to enter the scraper 35. Under the action of the spiral lifting member 30, the impurities rise and enter the reverse gear transmission assembly 43.

[0065] After initial cooling, the gas rises and contacts the inner coil assembly 7 for further cooling. During its flow, it also exchanges heat with the heat exchange medium in the heat absorption chamber 802. The rotation of the first fan blade assembly 22 allows the gas to be discharged from the end of the flue gas conveying assembly away from the incineration assembly 1. To ensure gas flow, corresponding air passages are provided on the flue gas conveying assembly, corresponding to the first fan blade assembly 22. The gas flow reduces the gas pressure at the lower end of the inclined member 19, causing the flue gas to flow towards the end of the flue gas conveying assembly away from the incineration assembly 1, thus providing power for the flue gas flow. The negative pressure pipe 42 also draws gas from the reverse gear transmission assembly 43, causing the gas in the scraper 35 and the conveying pipe 31 to move into the reverse gear transmission assembly 43.

[0066] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
