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.
Description
[0001] technical field [0002] The invention relates to a chain-type double-cavity drying device for raw material iron powder. Background technique [0003] Raw iron powder for primary reduced iron or powder metallurgy must be dry. Since the raw material iron powder contains moisture, it must be dried before use. The raw material iron powder drying devices currently used are all kiln-type single heating chamber structures, which are heated by gas. The disadvantage is that the heating time is long, the heating is uneven, the energy required for heating is large, and the cost is high. It is very unsafe to use gas heating. Contents of the invention [0004] In order to solve the problem that the currently used raw material iron powder drying devices are all kiln-type single heating chamber structures, using gas heating, the heating time is long, the heating is uneven, the energy required for heating is large, and the cost is high; using gas heating is very To solve the p...
