Abstract
The invention provides a chain type double-cavity drying device for raw iron powder. The chain type double-cavity drying device is of a double-layer structure and comprises an upper drying cavity and a lower drying cavity. The raw iron powder can be fully and evenly heated and dried. The raw iron powder is heated and dried by waste heat gas exhausted out of a tunnel kiln, so that energy is saved. By means of the structure that a scraper plate is welded with a chain, the chain can turn and drag the raw iron powder to move upwards in a process moving along a partition plate, the raw iron powder is quickened to be dried, the drying time is further shortened, and the efficiency is improved. Due to the fact that coal gas is not used form heating, the chain type double-cavity drying device for the raw iron powder is safer to use.
