Due to its low cost, coal slime blending has always been an important means to improve the profitability of circulating fluidized bed units. Since the blended coal slime has poor fluidity, strong adhesion, and many impurities, it is very easy to form adhesion and blockage in the raw coal hopper and coal drop pipe, which seriously restricts the increase in the amount of blending and becomes a bottleneck for the power plant to reduce losses and increase profits. Therefore, in the process of conveying blended coal slime, it is necessary to design a pipeline that can prevent adhesion and coal blockage to solve this problem.

9. A pipeline for preventing coal sludge from sticking and blocking coal according to claim 8, characterized in that: The transmission assembly comprises a transmission wheel to which the top end of the first drive shaft (1102) and the top end of the first transmission shaft (902) are fixed, and a transmission belt (10) is connected between the two transmission wheels.

10. A method for preventing coal sludge from sticking to and blocking a pipeline, characterized in that: The method is based on a pipeline for preventing coal slime from sticking and blocking coal as described in claim 1, comprising: The coal sludge enters the conveying pipeline (5) and flows out from the lower barrel (1). The crushing component (9) crushes the coal sludge in blocks, thereby preventing the coal sludge from crowding inside the pipeline and causing pipeline blockage.
