[0034] The working principle and use process of the present invention are as follows: when using, the cleaning device is installed on the waste heat boiler. When the waste heat boiler needs to be cleaned, the adjustable mounting cylinder 31 is driven to rotate by the driver 40. At this time, the cleaning mechanism 1 rotates following the adjustable mounting cylinder 31. When the cleaning mechanism 1 rotates, the limit transmission piston rod 20 moves in a direction away from the adjustable mounting cylinder 31 under the action of centrifugal force. At the same time, the hollow water dividing plate 12 moves in a direction away from the adjustable mounting plate 19 under the action of centrifugal force. Therefore, through the dual applicability adjustment, the adjustable cleaning scraper 14 can produce two-stage displacement relative to the adjustable mounting cylinder 31 during rotation, so that the adjustable cleaning scraper 14 is close to the inner wall of the boiler, thereby improving the applicability of the cleaning device, and the boiler is cleaned by the rotation of the adjustable cleaning scraper 14.

[0035] Secondly, while the adjustable cleaning scraper 14 is rotating to clean the dust, water is supplied to the metal feeding round pipe 35 through the rotating feeding joint 43. At this time, the metal feeding round pipe 35 delivers water to the bottom of the adjustable mounting cylinder 31. Then, the water at the bottom of the adjustable mounting cylinder 31 is delivered by the feeding hose 10 and dispersed by the hollow water dividing plate 12, and then sprayed out through the adjustable nozzle 13, so that the adjustable cleaning scraper 14 can spray water to wash the boiler while scraping the dust;

[0036] In addition, while the adjustable cleaning scraper 14 is rotating to clean dust, the first position adjustment plate 15 and the second position adjustment plate 21 are controlled to intermittently attract each other, so that the adjustable cleaning scraper 14 is intermittently moved toward the adjustable mounting cylinder 31, thereby realizing the lateral reciprocating movement of the adjustable cleaning scraper 14, and the intermittent knocking of the boiler is realized through the lateral reciprocating movement of the adjustable cleaning scraper 14, and the stubborn dust remaining on the boiler is removed by knocking, so that the boiler is quickly and fully cleaned through the mutual cooperation of the triple cleaning;

[0037] In addition, the position adjustment member 46 is controlled to retract, at which time the pressure regulating piston plate 42 moves downward to allow the transmission fluid 45 in the liquid storage tank 44 to enter the top of the transmission support cylinder 37, so that the adjustable mounting cylinder 31 moves away from the transmission support cylinder 37, so that the adjustable cleaning scraper 14 moves vertically, so that the user can adjust the height of the adjustable cleaning scraper 14 according to actual use requirements, further improving the applicability of the dust cleaning device, and by controlling the vertical reciprocating movement of the adjustable cleaning scraper 14 to achieve range cleaning of the boiler, through the mutual cooperation of the four-fold cleaning, the boiler can be cleaned in an all-round, fast and sufficient manner;

[0038] Therefore, through the mutual coordination of multiple structures, the user can quickly adjust the applicability of the cleaning device according to actual use requirements, so that the cleaning device can be suitable for different types of waste heat boilers, making the application range of the cleaning device wider. Secondly, the present invention can perform multiple cleanings on the boiler, so that the cleaning device has a better cleaning effect on the waste heat boiler. The present invention has a simple structure and is easy to use, and is worthy of promotion and use.

[0039] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
