Technical Field

[0001] This utility model relates to the technical field of ash removal devices, and in particular to an ash removal device for steam boiler flue tube bundles. Background Technology

[0002] During boiler operation, fly ash particles carried by the flue gas adhere to the inner wall of the flue tubes, forming ash deposits. These ash deposits have poor thermal conductivity, creating thermal resistance, significantly reducing the boiler's thermal efficiency and output, and potentially leading to safety accidents (such as blockage, corrosion, or even tube rupture). Regular and effective ash removal is necessary, thus creating an urgent need for a steam boiler flue tube bundle ash removal device.

[0003] For example, in a class of prior art represented by application number CN202321292297.4, the main structure includes a cuboid frame structure, a screw jack, a drive motor, a cleaning rod, and a long copper wire brush. The screw jack is fixedly connected to a support base, and a first straight pipe is welded to the support base. A set screw that abuts against a column is threaded onto the first straight pipe. A horizontal support plate is connected to the top of the screw, and four second straight pipes are welded to the horizontal support plate. The drive motor is fixed to the horizontal support plate, and the output shaft of the drive motor is fixedly connected to one end of the cleaning rod through a universal coupling. The long copper wire brush is fixedly installed to the other end of the cleaning rod. Its structure is simple, easy to process and assemble, has low development cost, strong applicability, and is easy to disassemble, store, and transport; it reduces the number of personnel required for cleaning work, lowers labor intensity, saves cleaning time, improves work efficiency, and enhances the cleaning effect.
