Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figure 1 、 Figure 2 and Figure 3, the present utility model provides a technical solution: a corrosion-resistant spiral finned tube, which includes a tube body 1. A positioning sleeve 3 is sleeved at both the left and right ends of the tube body 1. One end of the top of the positioning sleeve 3 is detachably connected to an installation support plate 6 through a nut. The middle of one end of the bottom of the positioning sleeve 3 is fixedly connected to a column pad 4. A slide bar 2 is fixedly connected to the top of one end of the installation support plate 6 and the middle of one end of the column pad 4. A protective sleeve ring 7 is slidably connected to the outside of the slide bar 2. The left end of the tube body 1 is fixedly connected to a gear head 5. By providing the gear head 5, the protective sleeve ring 7, and the slide bar 2, it is convenient to scrape and clean the dust accumulated between the fins on the spiral finned tube. During cleaning, it is relatively convenient and fast. A cylindrical cavity hole is provided in the middle of one side of the column pad 4 for supporting and clamping the positioning sleeve 3. One end of the bottom of the installation support plate 6 is detachably connected to a fixing block through a nut, and the bottom end of the fixing block is fixedly connected to the middle of the top end of the positioning sleeve 3 for installing and fixing the slide bar 2. A sliding cavity 11 is provided in the wall cavities at both the upper and lower ends of the protective sleeve ring 7, and the protective sleeve ring 7 is slidably connected to the slide bar 2 through the sliding cavity 11 for guiding the sliding track of the protective sleeve ring 7. One end of the rear side inside the protective sleeve ring 7 is fixedly connected to a scraper plate 9 for scraping the dust adhered between the fins. One end of the top end inside the protective sleeve ring 7 is fixedly connected to a high-temperature cleaning brush 10 for cleaning the scraped dust. Discharge ports 8 are provided on both the front and rear sides of the middle of the bottom end of the protective sleeve ring 7 for discharging the swept dust. A thread is provided at the connection between the gear head 5 and the tube body 1, and the gear head 5 is detachably connected to one end of the tube body 1 through the thread for detachably connecting the gear head 5. The thickness of the scraper plate 9 matches the distance between the fins on the spiral finned tube, and the thickness of the high-temperature cleaning brush 10 is the same as that of the scraper plate 9, which is convenient for scraping the ash slag adhered to the fin walls.
[0021] Working principle: During use, when an external object falls and collides with the sliding rod 2 above the pipe body 1, the sliding rod 2 blocks the colliding object and at the same time bounces it off. When it is necessary to clean the outer surface of the pipe body 1, the gear head 5 is clamped onto the driver, and the driver drives the engaged gear head 5 to rotate. The rotating gear head 5 drives the pipe body 1 connected at one end to rotate. The spiral fins on the rotating pipe body 1 will drive the scraper plate 9 and the high-temperature resistant cleaning brush 10 clamped between the fins to slowly slide along the spiral fins towards one end of the pipe body 1 as the pipe body rotates, thereby driving the protective sleeve ring 7 fixedly connected to the outside of the scraper plate 9 to slide along the sliding rod 2 towards one end. During the sliding process, the outer sides of the scraper plate 9 and the high-temperature resistant cleaning brush 10 are always in contact with the outer wall of the fins. The moving scraper plate 9 scrapes the dust on the inner wall of the contacted fins off the inner wall of the fins, and then the high-temperature resistant cleaning brush 10 sweeps the garbage falling on the surface of the fins into the inside of the protective sleeve ring 7, slides along the protective sleeve ring 7 to the slag discharge port 8 and is discharged from the slag discharge port 8, thus completing the cleaning of the dust on the outer surfaces of the pipe body 1 and the fins. And the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
[0022] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
