The raw coal bin is an important storage device for continuously supplying raw coal to a coal mill by a coal conveying system of a thermal power plant, and has basically the same structural shape, square upper part, cylindrical upper part, square lower part, conical lower part and hyperbolic lower part. The upper opening is large, the lower opening is small, the upper opening is used for feeding, and the lower opening is used for discharging materials. The materials in the raw coal bin fall down by gravity, and the materials flow downwards in the conical container, so that the area is smaller, the materials are extruded, and the friction coefficient is increased, which is the main cause of blockage. The key position of the raw coal bin where coal blockage occurs is in the range of 0-3 m from the upper part of an inlet of the coal feeder to the lower part of the coal bucket. In addition, the moisture content and thickness of the materials, the temperature change, the storage time of the materials in the window container and the friction coefficient of the container wall are all factors causing blockage. For a long time, the safety and stability of the operation of the power plant are always plagued by the harm caused by the coal blockage of the raw coal bin. The boiler fuel of the thermal power plant is influenced by coal supply, the boiler fuel of the current unit deviates from the original design coal types, particularly poor-quality coal and coal slime are blended and burned, so that the original coal bunker in the original unit design cannot adapt to the frequent coal blockage caused by the change of the coal types, particularly in rainy seasons, the coal slime has extremely strong viscosity, and the coal blockage problem is particularly easy to be caused at the coal bunker outlet and the coal pipe at the coal feeder inlet. Meanwhile, in winter, the temperature in the north is cold, wet coal and coal slime are extremely easy to generate a freezing phenomenon, coal flows are agglomerated due to the freezing, a blocking plug is formed at an outlet of a coal bin, and finally the coal blocking phenomenon of the whole coal bin is formed.
