Bendable umbrella type water jacket furnace smoke pipe cleaning device

The utility model relates to the technical field of water jacket furnace smoke pipe cleaning devices, in particular to a bendable umbrella type water jacket furnace smoke pipe cleaning device. The device comprises a header pipe, a stretch bar, an expansion bar, a central pipe and at least two scraping plates. The outer diameter of the stretch bar, the outer diameter of the expansion bar and the outer diameter of the central pipe are all smaller than the inner diameter of the header pipe. An upper limiting plate is fixed to the upper end of the header pipe and provided with an upper through hole. A lower limiting plate is fixed to the lower end of the header pipe and provided with a lower through hole. The middle of the stretch bar is mounted in the lower through hole. The bendable umbrella type water jacket furnace smoke pipe cleaning device is reasonable and compact in structure and convenient to use; the arranged scraping plates can clear up accumulated carbon in a smoke pipe and can scrape off both the accumulated carbon in the smoke pipe with the pipe diameter larger than that of the header pipe and the accumulated carbon in the smoke pipe with the pipe diameter smaller than that of the header pipe, so the cleaning effect of the accumulated carbon is improved, and the situation that the smoke pipe is corroded after a chemical cleaning method is adopted is avoided; an arranged flexible hose facilitates removal of the accumulated carbon on a U-shaped pipe section in the smoke pipe.
