Due to the structure of the bearing ring 308 itself, the rotating rod 4 can move up and down with the internal threaded barrel 304, and can also rotate and stir with the connecting rod 303, so that the rotating rod 4 and the heating rod 5 can The heating rod 5 is capable of performing up-and-down rotational stirring, so that the materials at each stacking level in the tank body can fully contact with the heating rod 5. At the same time, when the heating rod 5 rotates, it will drive the vertical plate 7 to rotate, and synchronously drive the rubber scraper 8 to scrape against the inner surface of the tank body, effectively preventing the materials from sticking to the inner wall of the tank body. The heating coil 9 in the inner wall of the drying tank 1 can heat up the drying tank 1 as a whole, heat and dry the surrounding materials, and cooperate with the heating rod 5 to quickly dry the materials. When the drying tank 1 is heated and dried, the hot air flow increases the internal air pressure. At this time, the gas will enter the mounting cylinder 1201 through the lower air notch 1203, push the piston 1205 upward, squeeze the telescopic spring 1204 upward, and then connect the upper air notch 1202 with the lower air notch 1203, and then release the excess gas inside to prevent the tank body from being deformed and ruptured due to excessive internal air pressure. This is the working principle of the automatic drying device for the production of iron oxide pigments.
