Description

Technical Field

[0002] Silos are mainly used to store grains, cereals, oil, feed, and other powdery and granular materials. Grain silos are large-scale storage equipment, mainly used to store various grains, feeds and other granular materials. Silos are the main storage buildings in the grain industry. At present, the storage method of silos is mainly to feed into the silo from a conveyor. Under the height of dozens of meters, the grain will produce dust during the descent due to its own gravity. Most of the dust will run out from the air vents on the top of the silo and affect the surrounding environment of the silo. Due to the large number of silo storage, their volume is large, and the distance between silos is far. The working mode is that one silo is feeding the feeder, and the other silo is not feeding synchronously. They are not synchronous. The traditional centralized dust removal method is not conducive to management, insufficient site area and load-bearing problems are not conducive to the design and construction of treatment equipment. For this reason, a silo independent environmental dust removal device is proposed. Utility Model Content
