Heat pipe-type double-cone dryer

The invention discloses a heat pipe-type double-cone dryer. The heat pipe-type double-cone dryer comprises a heat pipe drying bin, a support device, rotary joints, a vacuum unit, a driving device, a guide pipe and a valve. Heating heads of heating pipes of the heat pipe drying bin are installed and fixed on a bin body, the bin body of a drying bin is supported by the heating pipes supported and fixed by a fixing strip, and the thickness of a metal plate for manufacturing the bin body can be properly reduced. A high-temperature medium enters an inner cavity between a heating bin and the dryingbin, and heat energy carried by the medium carries outs heat conduction and heating on materials in the drying bin through the bin body of the drying bin and the heating pipes; the heat dissipation area of heaters with heating strips is increased by 8-35 times, the heaters conduct the heat energy to heat conduction working media, the heat conduction working media are subjected to heat conduction and heat exchange of liqui
