In the practical use of thermal power plants, almost all coal silos suffer from coal blockage to a greater or lesser extent, particularly in the extreme rainy season, where the water content of the coal increases, the viscosity of the coal particles increases, and coal plugging becomes more frequent. The specific reason is that the caliber of the outlet of the coal dropping pipe is reduced, the coal slime falls and impacts and the self-weight cause can be continuously adhered to the pipe wall, and the coal slime is accumulated to be thicker and thicker along with the lapse of time, so that the coal dropping port is further reduced, and coal blockage is caused. The continuity of the follow-up coal for power generation is influenced after the coal blockage of the power plant, and the loss is caused. The manual cleaning degree of difficulty is big, and is dangerous high, because the casualties that clear stifled the cause are few according to statistics investigation, so many producers have researched and developed the clear stifled device of different structural style, for example: the loosening machine is embedded and is arranged in a bin body of a raw coal bin, the loosening function can be realized in the initial stage after the loosening machine is arranged, but because the continuous flow and the pressure of coal are large, an oil cylinder can block the coal flow, when the coal is seriously blocked, a coal fluffing point is arranged at the position, when the raw coal bin is stuck with the coal, the rake moves up and down to dredge, but also occupies a large space, the coal flow is blocked, the coal flow flowing is influenced, and the fishbone-shaped rake can be quickly deformed and worn to be bare, so that the loosening function is not realized, the coal can be smoothly discharged, and when the loosening machine is actually operated, once the failure happens, the adverse effect is larger (if a connecting part of the loosening device is broken, the loosening function is lost, and the coal flow is not smooth), and the sticking and blocking of the raw coal bin are aggravated; high-frequency vibration type arch breaking machine: the main structure of the device generally comprises a movable bin body and an eccentric high-frequency vibrator, and the high-frequency vibrator is high in frequency, small in amplitude (about 1-2 mm), and easy to vibrate more and more compact due to the fact that the high-frequency vibrator is in transverse and longitudinal cross pressure, and the overall structural resonance of a raw coal bin layer often appears in actual operation, so that huge potential safety hazards are brought. Therefore, the automatic gasification blockage removing system provided by the invention has a wide application range, utilizes compressed air as power, and intelligently controls the pulse electromagnetic valve to periodically and automatically spray air so that materials cannot be bonded with the wall of the bin to remove blockage.
