Double-layer bulkhead steel plate silo

The invention relates to the technical field of storage equipment, in particular to a double-layer bulkhead steel plate silo. When grain is released, dust and fine impurities drift away in the air, an operator inhales the dust and the fine impurities into the body to influence the body health, and when grain is added, the same position of the steel silo is impacted all the time, deformation of the steel silo is easily caused, and the service life of the steel silo is influenced. A double-layer bulkhead steel silo comprises a support, an outer shell is welded to the upper end of the support, a heat preservation buffer mechanism is arranged in the outer shell, and a grain feeding mechanism, a ventilation dust removal mechanism and an up-down shaking mechanism are arranged in the heat preservation buffer mechanism. Temperature control over stored grains is achieved through the heat preservation buffering mechanism, grain dispersing impact force is evenly added into the equipment through the grain feeding mechani
