3, connecting bend outer tube hypomere outer wall welding ventilation sleeve pipe, outer tube and flange retain certain space simultaneously, this design can ensure that air evenly can enter outer tube from all directions, prevents air and only enters outer tube from side, thus cause the radiating effect of radiating tube undesirable.
4, in connecting bend, pipe stretches into radiating tube inside by tube connector, connecting bend outer tube is retained certain space with cover board of front end and is connected by seal sleeve, the running of radiating tube can not be hindered like this, the radiating tube tube length caused that expands with heat and contract with cold can be eliminated again and change the harmful effect brought.
5, attached cylinder bottom is provided with dust-collecting box, rubbish in the attached cylinder of easy cleaning, and dust-collecting box bottom cover plate is connected with box body by loose-leaf, simple and practical.
6, connecting bend adopts flange to be connected with body of heater, is convenient to I&M.
Energy-efficient drum drying equipment provided by the invention saves the fuel of 30% ~ 50% than existing drum drying equipment.
