The conductive type drum dryer comprises a
drum drying silo, a
discharge device, a supporting wheel bracket, a heating device, a drive device, an exhaust device, a tee
pipe, a gear ring, a fan, a sealing device and a bracket. The
drum drying silo includes a heating
silo, a
drying silo and a
heat conducting medium. The supporting wheel bracket supports the
drum drying silo. The exhaust device is fixed on a
flange of an exhaust port of the tee
pipe, one end of the
discharge device is fixedly connected with a
flange of a feed hole of the tee
pipe, and the other end of the
discharge device is fixedly connected with a hopper. A discharge hole of the tee pipe is sealingly, dynamically and fixedly connected with a feed hole of the drum
drying silo through the sealing device. When one
heat pipe is damaged and leaks, that is to say, only the one
heat pipe can not work and the use of the whole
drying silo is not affected. The drum drying silo rotates under driving of the drive device, a spiralblade has the function of agitation and propulsion, materials do not
agglomerate easily in the drying silo, and the dried material is cooled in a cooling section, so that the drying efficiency of thematerials is improved and the drying effect of the materials is optimized.
