[0002] In industrial production, the spiral blanking device of the silo is a very key link. It can accurately control the speed of blanking, and by adjusting the rotating speed of the spiral blade, the material can enter the subsequent process with appropriate flow according to the production process requirements, preventing too fast or too slow blanking. With the continuous rotation of the spiral blade, the material can uniformly flow out of the discharge port, avoiding segregation and ensuring uniform distribution of the material entering the subsequent link. At the same time, it also has the function of preventing blockage, and the stirring and loosening effect of the spiral blade can ensure smooth falling of the material that is easy to agglomerate and bridge. For production with accurate metering requirements, it can realize quantitative blanking in cooperation with metering equipment. Moreover, its sealing structure can prevent material dusting, protect the environment, and be suitable for various special materials.
