在钢板仓下部内壁处安装两组半园形的环形风道，在筒壁内园周等距离安装20个垂直风道，在环形和垂直风道壁上冲有空气分配孔，使其与仓外高压风机配套形成贮粮通风系统。在每年9、10、1－2月对贮粮分三个阶段进行通风降温，能保证钢板仓长期安全贮粮。 Two sets of semicircular annular air ducts are installed on the inner wall of the lower part of the steel silo, 20 vertical air ducts are equidistantly arranged in the cylinder wall, and air distribution holes are punched in the annular and vertical air duct walls to make it connect with the silo External high pressure fan supporting the formation of grain storage ventilation system. In 9, 10, 1-2 months of stored grain in three stages of ventilation and cooling, steel silos to ensure long-term safety of grain storage.
