Embodiment Construction
[0011] Such as figure 1 , 2, the present invention includes a raw coal bunker 1, a rotating loose rod 2, a loose rod connector 3, a steering coupling 4, a reducer 5, a sealing device 9 and an electric control box 11.
[0012] There are three rotating loosening rods 2 with the same length, installed in the raw coal bunker 1, and combined into a cone shape, the top junction point 12 is connected by a loosening rod connector 3, so that each rotating loosening rod 2 can rotate freely, and the bottom end passes through The steering coupling 4 is connected to the output shaft 6 of the reducer 5; several layers of scrapers 10 with different lengths are installed on the rotating loosening rod 2, and ensure that when the rotating loosening rod 2 rotates, the adjacent rotating loosening rod 2 The scrapers 10 do not interfere with each other; and the blades of the scrapers 10 face down to prevent foreign objects from hanging.
[0013] A sealing device 9 is installed at the opening posit...

The invention discloses a raw coal bunker loosening and dredging device which comprises a raw coal bunker, a rotary loosening rod, a loosening rod connector, a steering coupler, a speed reducer, a sealing device and an electric cabinet. The raw coal bunker loosening and dredging device is used for loosening coal through a multi-directional combined rotary cut movement of a scraper on the rotary loosening rod, prevents the coal from shedding and arching, enables the raw coal in the raw coal bunker to keep a flowing state, thereby thoroughly solving the problem of blockage of the raw coal bunker. The device has the characteristics of low cost, simple structure, convenience in installation, wide dredging range, and strong practicability, is mainly applied to blockage prevention of the raw coal bunker of a boiler in a thermal power plant, and is applicable to various kinds of coal such as coal slime, brown coal and frozen coal.
Description
technical field [0001] The invention relates to a loosening and dredging device, in particular to a loosening and dredging device for a raw coal bunker. Background technique [0002] The blockage of the raw coal bunker is a long-standing problem in thermal power plants. It usually occurs in the lower cone of the raw coal bunker. The cost of equipment is high, the structure is huge, the installation is complicated, and the dredging effect is not ideal when using coal with strong agglomeration such as coal slime. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a raw coal bunker loosening and dredging device with low cost, simple structure, good anti-blocking and loosening effect, and suitable for coal slime, lignite, frozen coal and other coal qualities. [0004] For realizing the above object, technical scheme of the present invention is: [0005] A raw coal bunker loosening and dredging d...
