[0027] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments, and all other embodiments obtained by the person skilled in the art without creative labor on the basis of the embodiments in the utility model belong to the protection scope of the utility model.

[0028] Embodiment 1

[0029] Figures 1 to 3 As shown, an embodiment of the utility model provides a steam conveying pipeline internal cleaning device, and the cleaning device comprises:

[0030] The cleaning ring 10 is cylindrical and is provided with openings at both ends, a plurality of spiral blades 11 are arranged on the inner wall of the cleaning ring 10, a plurality of scrapers 12 are arranged on the outer wall of the cleaning ring 10, and the plurality of spiral blades 11 and the plurality of scrapers 12 are uniformly distributed around the axis of the cleaning ring 10;

[0031] The elastic sleeve 20 is located at both ends of the cleaning ring 10, the cleaning ring 10 and the elastic sleeve 20 are rotationally connected, the elastic sleeve 20 is a cylindrical structure with openings at both ends, the elastic sleeve 20 at both ends is connected by the fixing part 30 and the fastening shaft 40, the elastic sleeve 20 at both ends of the cleaning ring 10 is rotationally connected to the cleaning ring 10 under the connection of the fixing part 30 and the fastening shaft 40, wherein the fixing part 30 comprises a fixing ring 31, a center fixing sleeve 32 and a connecting strip 33, the fixing ring 31 and the center fixing sleeve 32 are concentrically arranged, the fixing ring 31 is located outside the center fixing sleeve 32, the both ends of the connecting strip 33 are fixed to the fixing ring 31 and the center fixing sleeve 32 respectively, the both ends of the fastening shaft 40 are fixed to the center fixing sleeve 32 at both ends of the cleaning ring 10.

[0032] The steam conveying pipeline internal cleaning device disclosed in the embodiment is used in cooperation with air blowing or liquid flushing. In use, a cleaning device with a proper size is selected according to the inner diameter of the steam pipeline, so that the outer diameter of the elastic sleeve 20 is slightly larger than the inner diameter of the steam pipeline, and a large friction force exists between the elastic sleeve 20 and the steam pipeline. The cleaning device with a proper size is put into the steam pipeline, and then a high-speed flowing fluid (air, steam or water, etc.) is introduced into the steam pipeline. The pressure at both ends of the cleaning device is different, and the high-speed flowing fluid pushes the cleaning device to move in the steam pipeline when the fluid flows in the steam pipeline. Since the cleaning ring 10 is a cylindrical structure with openings at both ends, the fluid flows from the high-pressure end of the cleaning ring 10 to the low-pressure end and drives the cleaning ring 10 to rotate through the spiral blade 11. When the cleaning ring 10 rotates, the scraper 12 rotates with the cleaning ring 10. The end of the scraper 12 away from the cleaning ring 10 contacts the inner wall of the steam pipeline and scrapes off the stains on the inner wall. In the process of moving of the cleaning device, the scraper 12 cleans the inner wall of the steam pipeline one by one. Since the elastic sleeve 20 and the cleaning ring 10 are rotationally connected, the elastic sleeve 20 and the steam pipeline have a large friction force, and the elastic sleeve 20 will not rotate in the steam pipeline. When the fluid flows through the cleaning ring 10, its speed increases due to the reduction of the diameter, so as to drive the scraper 12 to rotate at a high speed. The same position is usually cleaned multiple times, so as to improve the cleaning effect. The elastic sleeve 20 plays a role of limiting the cleaning ring 10.

[0033] The utility model discloses a steam delivery pipeline internal cleaning device sets up cleaning ring 10 and elastic cover 20, the inside of cleaning ring 10 is provided with helical blade 11, the outside of cleaning ring 10 is provided with scraper 12, when cleaning pipeline, elastic cover 20 is driven under the push of high -speed fluid and moves along the inside of steam pipeline with cleaning ring 10, simultaneously, high -speed fluid passes through helical blade 11 and pushes cleaning ring 10 rotation, so that scraper 12 can scrape the stubborn stain of steam pipeline inner wall, relative to prior art, the utility model can improve the cleaning effect of steam pipeline.

[0034] Specifically, in the embodiment, the cleaning ring 10 is a metal sleeve, the helical blade 11 is fixed on the inner wall of the cleaning ring 10 by welding, and the cleaning ring 10 forms an impeller structure.
