Novel heat tracing device for tracing heat by using heat source of main pipeline

The utility model discloses a novel heat tracing device utilizing a heat source of a main pipeline to trace heat in the technical field of conveying and heating devices, which comprises a heating main pipe with two closed ends, and the side face of the heating main pipe is respectively communicated with a first connecting pipe and a second connecting pipe. A plurality of groups of heat conducting pieces which are circumferentially arranged at equal intervals around the central axis are welded on the outer ring of the heating main pipe; a conveying branch pipe penetrates through the middle of each heat conduction piece, the two ends of each conveying branch pipe communicate with the conveying main pipe through flow dividing pieces, and a heat preservation pipe wrapping the heating main pipe, the heat conduction pieces and the conveying branch pipes is arranged between the two flow dividing pieces. The heat tracing device solves the problems that an existing heat tracing device usually directly winds an electri
