Efficient heat preservation structure of conveying pipeline

The invention relates to an efficient heat preservation structure of a conveying pipeline, the conveying pipeline sequentially comprises an outer heat preservation pipe, a pipeline body and an inner heat preservation pipe from outside to inside, the outer heat preservation pipe comprises a sheath layer and a heat insulation layer, the inner heat preservation pipe comprises a plurality of inner heat preservation units and pull rods, and each inner heat preservation unit comprises a base body, a flow guide pipe and an aerogel layer. The base body comprises a connecting ring and a flow guide block, aerogel layers are arranged on the inner circumferential wall of the flow guide pipe, the surface of the base body and the outer circumferential wall of the flow guide pipe outside the base body, and the multiple inner heat preservation units are sequentially connected through pull rods to form a pipe shape. The heat preservation and insulation capacity of the pipeline can be enhanced, and material heat loss is reduce
