<p>The invention provides a drying device, which comprises a cylindrical filter cartridge 11 coiled by a porous plate 13. The two ends of the cylindrical filter cartridge 11 are sealed by end plates 12. The inner side of the cylindrical filter cartridge 11 is served as a rotary barrel 1 for a drying chamber 2. The rotary barrel is driven to rotate by a drive mechanism 3. A heating air supply mechanism 4 forcibly sends heating air into the rotary barrel 1. In the rotary barrel 1, a plurality of rods 15 are arranged to be away from the inner side of the filter cartridge 11 so as to be into a cylindrical rod cylinder 5 and divide the drying chamber 2 into a first drying chamber 2A and a second drying chamber 2B. Due to the adoption of the drying device, materials to be dried are fed into the first drying chamber 2A through an opening part 20 and are dried in the first drying chamber 2A of the rotary barrel 1. Therefore, the materials fall through a dropping gap 16 into the second drying chamber 2B. Then the materials are further dried in the second drying chamber 2B and are discharged to the outside through the through holes 14 of the porous plate 13.</p> |
