[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, and the following embodiments are used to illustrate the utility model.

[0028] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a boiler flue gas filtering device comprises a boiler body 20, the boiler body 20 is a hollow cylinder in the cavity, a filter element is installed in the cavity of the boiler body 20, the top of the boiler body 20 is fixedly connected with a smoke outlet pipe 21, the smoke outlet pipe 21 is a reverse L-shaped round pipe, the bottom of the smoke outlet pipe 21 can communicate with the cavity of the boiler body 20, the top of the smoke outlet pipe 21 is installed with a support, the top of the support is fixedly connected with a servo motor 22, the servo motor 22 is electrically connected with the corresponding power supply, which is the prior art, so it is not described here.

[0029] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the anti-water-entry structure is installed on the wall of the smoke outlet pipe 21 to prevent rainwater from entering the cavity of the smoke outlet pipe 21. The anti-water-entry structure includes: a fixed ring 30, a collar 31, and a smoke exhaust pipe 32. The fixed ring 30 is fixedly connected to the opening on the side wall of the smoke outlet pipe 21, the collar 31 is sleeved on the wall of the fixed ring 30, and the smoke exhaust pipe 32 is fixedly connected to the wall of the collar 31. The smoke exhaust pipe 32 can communicate with the cavity of the smoke outlet pipe 21.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the fixed ring 30 is circular, the collar 31 is a circular ring with a U-shaped cross-section, and the exhaust pipe 32 is an L-shaped circular pipe. The inner arc opening of the collar 31 can be adapted to the size of the fixed ring 30. The diameter of the exhaust pipe 32 is the same as the diameter of the exhaust pipe 21. The anti-pollution structure also includes a rotating wheel 33, a biting tooth 34, and a scraper 35. The rotating wheel 33 is fixedly connected to the output end of the servo motor 22, and the servo motor 22 can drive the rotating wheel 33 to rotate. The biting tooth 34 is fixedly connected to the outer arc surface of the collar 31, and the scraper 35 is fixedly connected to the exhaust pipe 21. On the inner wall of the flue 32, the rotating wheel 33 is gear-shaped and the biting tooth 34 is tooth-shaped. The rotating wheel 33 can mesh with the biting tooth 34. The biting tooth 34 is arranged in a ring array on the outer arc surface of the collar 31. The scraper 35 is a rod with a triangular cross section. The wall surface of the scraper 35 can also contact the inner wall surface of the opening of the flue 21. The anti-pollution structure also includes a protective plate 36. The protective plate 36 is composed of a rectangular plate in the lower half and a semi-circular tube in the upper half. The flue 21 and the servo motor 22 are located below the semi-circular tube of the protective plate 36.

[0031] In practical use, the flue gas in the boiler body 20 cavity will be discharged from the flue pipe 21 after passing through the filter element. After passing through the flue pipe 21, the flue gas will enter the exhaust pipe 32 and finally be discharged from the opening of the exhaust pipe 32. When rain protection and exhaust are required at the same time, the power of the servo motor 22 is turned on. The servo motor 22 can drive the rotating wheel 33 to rotate. When the rotating wheel 33 rotates, the teeth on its wall will mesh with the teeth 34. As the rotating wheel 33 rotates, the collar 31 can rotate on the outer wall of the fixed ring 30 through the teeth 34. When the collar 31 rotates, it will drive the exhaust pipe 32 to rotate from the original opening upward state to the opening downward state. When the collar 31 rotates, it will also drive the scraper 35 to scrape in the cavity of the flue pipe 21, scraping off the accumulated dust attached to the inner wall of the flue pipe 21. The protective plate 36 can shield the servo motor 22 and the collar 31 above.

[0032] In summary, by setting the anti-flood structure, the position of the smoke exhaust pipe 32 opening can be adjusted by rotating the smoke exhaust pipe 32, so that the boiler body 20 can normally exhaust smoke even in rainy weather without being immersed in the device by rain, and the protective plate 36 can prevent the exposed structure from being rained on, so the practicability of the present application is higher than that of the prior art.

[0033] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 5 , the wall surface of the smoke pipe 21 is also provided with a collection structure, which includes an ash collection groove 40, an alignment plate 41, a collection box 42 and a push block 43. The ash collection groove 40 is opened on the inner corner bottom wall surface of the smoke pipe 21. The alignment plate 41 is fixedly connected to the top of the boiler body 20 below the smoke pipe 21. The collection box 42 is clamped below the smoke pipe 21. The push block 43 is rotatably connected to the rear wall surface of the collection box 42. The ash collection groove 40 is a rectangular groove. The collection box 42 is a hollow rectangular box with an open top. The alignment plate 41 is an L-shaped section plate. The inner corner of the alignment plate 41 can match the size of the collection box 42. The top of the collection box 42 can communicate with the ash collection groove 40. The push block 43 is an L-shaped block. The inner corner of the push block 43 can be clamped to the top of the alignment plate 41.

[0034] In specific use, the accumulated ash scraped off in the cavity of the smoke pipe 21 will fall into the ash collection groove 40. The accumulated ash will pass through the ash collection groove 40 and accumulate in the cavity of the collection box 42. When the cavity of the collection box 42 needs to be cleaned, the push block 43 is pushed to a flat state. At this time, the collection box 42 can be taken out from the alignment plate 41 and cleaned. Then, the top opening of the collection box 42 is aligned with the ash collection groove 40, and the push block 43 is pushed downward to be clamped to the top of the alignment plate 41, thereby completing the installation of the collection box 42.

[0035] In summary, by setting the collection structure, the accumulated ash scraped off by the scraper 35 can be collected, so that the cavity of the smoke pipe 21 does not need to be cleaned regularly. Only the accumulated ash in the cavity of the collection box 42 needs to be cleaned, thereby effectively reducing the working pressure when cleaning the device.

[0036] Working principle: when rain prevention and smoke exhaust are needed, the power of the servo motor 22 is started. The servo motor 22 can drive the rotating wheel 33 to rotate. When the rotating wheel 33 rotates, the teeth on the wall surface of the rotating wheel 33 will engage with the teeth 34. With the rotation of the rotating wheel 33, the sleeve ring 31 can rotate on the outer wall surface of the fixed ring 30 through the teeth 34. When the sleeve ring 31 rotates, it can drive the smoke exhaust pipe 32 to rotate from the original opening upward state to the opening downward state. When the sleeve ring 31 rotates, it can also drive the scraper 35 to scrape in the cavity of the smoke pipe 21. The accumulated ash adhering to the inner wall surface of the smoke pipe 21 is scraped off. The protective plate 36 can shield the servo motor 22 and the sleeve ring 31 above.

[0037] It can be understood that the utility model is described through some embodiments, and the person skilled in the art knows that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the utility model. In addition, under the guidance of the utility model, these features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the utility model. Therefore, the utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application belong to the scope protected by the utility model.
