Air flow drying machine

Abstract

The invention relates to an air flow drying machine. The air flow drying machine comprises a conveying pipe (1). A fan (2) is arranged at the bottom of the conveying pipe (1). A material barrel (3) isarranged in the lower middle portion of the conveying pipe (1). A secondary heating device (4) is arranged in the upper middle of the conveying pipe (1). According to the air flow drying machine, thesecondary heating device is arranged on the conveying pipe; heat needed by the secondary heating device can be acquired from external conveying; and in this way, secondary heating can be acquired bymaterials in the upward conveying process, and the drying effect of the materials is guaranteed.

Description

technical field [0001] The invention relates to an airflow dryer, which belongs to the technical field of material drying. Background technique [0002] The airflow dryer is that when the wet material enters the machine, it is crushed at a high speed and strongly in the inhaled hot air. The collision, friction and shearing of the material make the material fine and dehydrated quickly. The materials running upwards are affected by the classifying device rotating above, and the coarse and wet materials go back to the crushing section for further crushing and drying. [0003] During the drying process of the existing materials, the temperature of the air gradually decreases during the process of being transported upward by the airflow, which leads to the inability to fully meet the drying heat demand of the materials, so that the drying effect and stability of the materials cannot be guaranteed, and further improvement is needed . Contents of the invention [0004] The purp...
