[0002] The flue is mainly used to convey flue gas with a certain temperature. A large amount of impurities will be contained in the flue gas. The particulate dust, impurities, etc. attached to the flue gas will adhere to the inner wall of the flue. With the long-term accumulation of dust and impurities, the cross-sectional area of the pipeline will become smaller, and even cause pipeline blockage. The reduction of the cross-sectional area of the pipeline leads to an increase in pressure and an increase in the load of other equipment. Therefore, it is necessary to stop the machine regularly for cleaning.

[0003] The structure and size of the commonly used cleaning equipment are fixed. Therefore, it can only be applied to the cleaning of flues with specific specifications. Moreover, during the cleaning process, when the dust on the pipe wall is scraped off, a large amount of dust will be raised, thus affecting the surrounding environment. Even if the pipeline is cleaned in a closed manner, these raised dust will float in the air for a long time and cannot be discharged. After the cleaning is completed, it will adhere to the pipe wall again, and the cleaning is not thorough. Content of the Utility Model

[0024] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant drawings. Embodiments of the present application are shown in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0026] Combined with Figures 1-5 As shown, a flue duct ash cleaning device includes:

[0027] The flue duct body 1, which is a cylindrical metal pipe and has a large amount of dust adhered to its inner wall;

[0028] The fixing seats 2, two of which are provided and are respectively arranged at both ends of the flue duct, used for auxiliary fixing of the entire device, and a transmission shaft 21 is rotatably installed between the two fixing seats 2, and a driving motor 22 is equipped on one of the fixing seats 2;

[0029] The cleaning member 3, which is the main cleaning part of the entire device and is movably assembled with the transmission shaft 21. A scraper 32 is arranged around its periphery and moves along the extension direction of the transmission shaft 21 through cooperation with the transmission shaft 21, and simultaneously uses the scraper 32 to scrape the dust on the inner wall of the flue duct body 1;

[0030] The adjusting assembly 4 is used to control the expansion and contraction of the fixing base 2 and the cleaning member 3, so as to fix and clean flue ducts of different specifications.

[0031] Specifically; in this embodiment, 4 support rods 23 are arranged around the fixing base 2. A rubber pad is provided at the bottom end of each support rod 23, and anti-slip patterns are provided on the bottom surface of the rubber pad. The staff first manually cleans the dust at both ends of the flue duct body 1, and then uses the adjusting assembly 4 to control the expansion length of the 4 support rods 23, so that the 4 support rods 23 all simultaneously abut against the inner side wall of the flue duct body 1 to achieve preliminary fixation. Then, the transmission shaft 21 is rotatably installed between them. At this time, the transmission shaft 21 is exactly concentric with the flue duct body 1.

[0032] The cleaning member 3 and the fixing base 2 are provided as circular plates of the same size, and both are hollow inside. 4 openings are provided on the outer side wall, and 4 chutes are formed by the 4 openings extending inward. An installation groove is also provided at the center of this space.

[0033] The adjusting assembly 4 includes an adjusting disk 41 and adjusting rods 42. The adjusting disk 41 is exactly embedded inside the installation groove and is rotatably connected to the inner wall of the cleaning member 3 or the fixing base 2 through a bearing structure. Moreover, a spiral adjusting groove is provided on the top surface of the adjusting disk 41. 4 adjusting rods 42 are provided and are respectively slidably inserted into the 4 chutes. The inner ends of the adjusting rods 42 are exactly located on the top surface of the adjusting disk 41, and a protruding portion is also provided on the side wall of the adjusting rod 42. The protruding portion is slidably inserted into the adjusting groove to form a chuck structure, and the arc-shaped inner wall of the adjusting groove is used to drive the 4 adjusting rods 42 to move inward or outward.

[0034] A worm gear 43 is also provided on the back surface of the adjusting disk 41. One side of the worm gear 43 is equipped with a worm 44. The two ends of the worm 44 are respectively rotatably connected to the inner wall of the cleaning member 3 or the fixing base 2, and one end extends to the outside and is provided with an adjusting cap 45. A hexagonal hole is provided at the center of the end face of the adjusting cap 45.

[0035] Based on the above structure, the outer ends of the adjusting rods 42 on the fixing base 2 are fixedly connected to the ends of the support rods 23. Therefore, when the adjusting rods 42 contract inward, the 4 support rods 23 synchronously contract toward the center. If the adjusting rods 42 expand outward, the 4 support rods 23 synchronously expand outward to assist in fixing flue duct bodies 1 of various specifications.

[0036] On the cleaning piece 3, an auxiliary bracket 31 is arranged on the periphery of the cleaning piece 3. The auxiliary bracket 31 is arranged in a ring shape and the inside is arranged to be hollow, and the hollow part is aligned with the four openings. At the same time, on the auxiliary bracket 31, it is divided into four areas of equal size by a solid plate, and a scraper 32 is slidably installed in the hollow part of each area. When the scraper 32 is retracted to the inside of the auxiliary bracket 31, it can form a complete circle.

[0037] The adjusting rods 42 on the four openings all extend outward and their ends are fixedly connected to the inner arc surfaces of the four scrapers 32. Therefore, when the four adjusting rods 42 are unfolded outward, the four scrapers 32 are also unfolded outward, so that the scrapers 32 can be suitable for the flue body 1 with a larger inner diameter.

[0038] In actual use, dust will frequently fall from above and then be lifted up when scraping, filling the air with a large amount of dust. This dust can easily affect the surrounding environment, and the dust floating in the air cannot be effectively cleaned. It is easy to re-adhere to the inner wall of the flue after cleaning.

[0039] Therefore, in order to clean thoroughly, in this embodiment, the interior of the auxiliary bracket 31 should be set to be hollow, and a plurality of atomizing nozzles 33 should be arranged at intervals on its outer wall. A water inlet 34 is provided on the surface of one end of the auxiliary bracket 31 close to the center. One end of the water inlet 34 is connected to the atomizing nozzle 33 through a water pipe, and the other end of the water pipe extends outward through a hose and is connected to a water pump. Therefore, with the cooperation of the atomizing spray, even dust will be quickly captured by the water mist and fall into the flue and be cleaned, which greatly improves the surrounding environment during work and makes cleaning more thorough and convenient.

[0040] The cleaning member 3 can complete horizontal movement by being driven unidirectionally by the transmission shaft 21 only. In order to further improve the stability of the cleaning member 3, a shaft sleeve should be provided at the center of the cleaning member 3. The shaft sleeve and the transmission shaft 21 should form a ball screw structure.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
