[0002] The coal drop pipe is a general term for the pipeline system used to transport coal in industries such as coal, ports, thermal power, coal transfer stations, coal washing plants, and coal-fired industrial boilers. This system usually includes key components such as coal drop hoppers, downpipes, and guide troughs. For longer coal drop pipes, air locks are also required to effectively reduce dust; if diversion is required, additional components such as diversion flap doors will also be added.

[0003] However, in the existing fuel transportation process, the coal drop pipe often encounters some problems after long-term use. Coal slag will gradually remain and adhere to the inner wall of the large hopper. As time goes by, these coal slags will continue to accumulate, forming a thick adhesion layer, and eventually cause blockage.
