Abstract

The invention relates to a rotary drying machine and a material drying method. The rotary drying machine comprises a barrel (1). The barrel (1) comprises an outer barrel (11) and an inner barrel (12) located in the outer barrel (11), and a jacket layer (13) is arranged between the outer barrel (11) and the inner barrel (12). Supporting pieces (3) are arranged in the inner barrel (12), each supporting piece (3) is provided with at least one mounting hole (31) for mounting heat exchange tubes (4), and the heat exchange tubes (4) on the outermost sides of the supporting pieces (3) are communicated with the jacket layer (13) through the inner barrel (12). The rotary drying machine and the material drying method have the advantages of being good in material drying effect, high in drying efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of material processing, and in particular relates to a rotary dryer and a material drying method. Background technique [0002] Polyvinyl alcohol (PVA) is an important chemical raw material for the manufacture of construction glue, textile pulp, polyvinyl butyral, gasoline-resistant pipes and vinylon synthetic fibers, fabric treatment agents, emulsifiers, paper coatings layers, adhesives, glues, etc. Among them, drying is one of the important processes for producing PVA finished products and ensuring the quality of downstream industrial products. The drying performance, structural characteristics, difficulty of manufacturing and processing, manufacturing costs, and operating conditions of the dryer directly affect the quality of the final PVA product. [0003] At present, the dryers used by domestic PVA manufacturers are basically traditional rake dryers introduced from Japanese production lines in the earl...
