Technical Field

[0001] The utility model relates to the technical field of coking dust removal, in particular to an ash discharging and blockage clearing device for a horizontal dust removal pipeline. Background Art

[0002] In the field of coal coking dust removal, due to the high concentration of pulverized coal and coke powder and the high viscosity of dust, during the process of mechanical dust removal, the pulverized coal and coke powder often settle in the horizontal dust removal pipeline. After running for a period of time, the horizontal dust removal pipeline will be blocked, resulting in poor mechanical dust removal effect.

[0003] At present, operators usually manually discharge ash and clear blockages, which has a large labor intensity and long labor time. Moreover, dust often escapes during the process of discharging ash and clearing blockages, which not only poses a threat to the health of operators, but also pollutes the environment. Content of the Utility Model

[0005] In order to achieve the above purpose, the utility model is realized by adopting the following technical solutions:

[0006] An ash discharging and blockage clearing device for a horizontal dust removal pipeline includes a scraper mechanism, a blowing assisting mechanism and a dust removing mechanism; the scraper mechanism is installed inside the horizontal dust removal pipeline and cleans the inner wall of the horizontal dust removal pipeline by rotating the scraper; the blowing assisting mechanism includes a blowing assisting gas pipeline connected to an external gas source, and the blowing assisting gas pipeline is installed above the horizontal dust removal pipeline and communicated with it, and is used for blowing gas into the horizontal dust removal pipeline to accelerate the flow rate of the deposited dust; the dust removing mechanism includes a dust collecting box and an induced draft fan, the dust collecting box is connected to the horizontal dust removal pipeline, and the dust in the horizontal dust removal pipeline is sucked into the dust collecting box by the induced draft fan.

[0007] Further, the scraper mechanism includes a rotating shaft, the rotating shaft is horizontally installed inside the horizontal dust removal pipeline and is rotationally connected to the horizontal dust removal pipeline; a plurality of scrapers circumferentially distributed on the rotating shaft form a set of scrapers, and multiple sets of scrapers are arranged on the rotating shaft along the axis direction of the rotating shaft, and there is a gap between each set of scrapers.

[0008] Further, a set of scrapers includes three scrapers, and the three scrapers are circumferentially distributed on the rotating shaft.
