Description

Technical Field

[0001] The invention relates to the technical field of flue cleaning, and in particular to a boiler flue cleaning device which is not prone to getting stuck. Background Art

[0002] The boiler flue is deep and needs to be cleaned with a dust cleaning device. Patent No. CN201811525941.1 discloses a dust cleaning device for a boiler flue. The transmission screw rotates and cooperates with the nut to drive the support plate to rotate in a circle. The support plate squeezes the guide rod against the inner wall of the guide hole. The force is decomposed to obtain the axial and radial forces along the guide rod, which drives the scraper and wire brush on the outside to sweep away the dust and oil on the inner wall of the flue. However, the rotation of the transmission screw and the rotation of the support plate guided by the guide rod are prone to interfere, causing the support plate to be stuck and unable to rotate, and then unable to move along the guide rod, causing the device to stop running. Moreover, the dust and oil stains are mixed to form oil clumps, which will fall on the guide rod at the rear after being discharged from the sewage outlet and attached. As the support plate moves, it is brought into the guide hole, increasing the friction and increasing the probability of the support plate getting stuck. Therefore, designing a boiler flue dust cleaning device that can prevent the scraper from stopping and eliminate the interference of scraped oil stains has become a technical problem that needs to be solved urgently. Summary of the invention
