Description
Technical Field
[0001] The utility model relates to the technical field of expansion agent production, in particular to a drying device for producing magnesia concrete expansion agent. Background Art
[0002] The main expansion source of magnesium concrete expansion agent is magnesium oxide, which does not contain sodium salt and will not cause alkali-aggregate reaction of concrete. It has good durability, stable expansion performance, and continuously increasing strength. Ordinary concrete often leaks due to shrinkage cracking, which reduces its use function and durability. Adding 6-12% expansion agent to concrete can make shrinkage compensation concrete, which greatly improves the crack resistance and waterproof ability of concrete structure. External waterproofing operation can be cancelled, the spacing of post-casting joints can be extended, and the appearance of temperature difference cracks in large-volume concrete and high-strength concrete can be prevented. In the production process of concrete expansion agent, it needs to be dried, and the wet expansion agent is sticky. When it is put into the dryer, it will stick to the feed inlet and even block the feed inlet, affecting the work efficiency, so as to improve its own storage time.
[0003] Due to the accumulation of concrete expansion agents, during the drying process, the materials on the outer surface are dried more thoroughly, but the materials in the center are heated unevenly due to the slow heat transfer rate of the expansion agent. The drying rate of the materials in the center is often very low, and the materials need to be manually turned over, resulting in uneven heating. In addition, after a large amount of expansion agents are dried, it is troublesome to remove them from the machine, which is time-consuming and labor-intensive. Utility Model Content
