Conduction type drum dryer

Abstract

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.

Description

technical field [0001] The invention relates to a tumble dryer, in particular to a conductive tumble dryer. Background technique [0002] Now on the market, there are drying equipment for materials such as grain, chemical products, coal, stones, sand, mineral products, pasture, crops, and local specialties. The heating of materials drying on the market is to dissipate heat through metal pipes placed in parallel. Or the secondary heat exchange through the heat exchanger outside the drying equipment is hot air, the heat exchange efficiency of heat energy is low, and the heat energy required for drying will increase a lot. The heat exchange tube in the drum drying bin leaks and is not easy to repair, resulting in the scrapping of the drum drying bin and making it unusable. The dried material has dead corners, and the material is easy to form agglomerates, which affects the uneven drying moisture of the material, and the dried material cannot be cooled.

[0002] Now on the market, there are drying equipment for materials such as grain, chemical products, coal, stones, sand, mineral products, pasture, crops, and local specialties. The heating of materials drying on the market is to dissipate heat through metal pipes placed in parallel. Or the secondary heat exchange through the heat exchanger outside the drying equipment is hot air, the heat exchange efficiency of heat energy is low, and the heat energy required for drying will increase a lot

The heat exchange tube in the drum drying chamber leaks and is not easy to repair, resulting in the scrapping of the drum drying chamber and making it unusable

The dried material has dead corners, and the material is easy to form agglomerates, which affects the uneven drying moisture of the material, and the dried material cannot be cooled.
