Abstract

The invention discloses an air supply and exhaust interchange system for a thermal insulation sealed grain dryer. The air supply and exhaust interchange system comprises a first air duct (3), a third air duct (10), a cold air blower (13) and a fifth air duct (15), wherein one end of the first air duct (3) is communicated with one joint of a first tee joint (2); the other end of the first air duct (3) is communicated with a cover air inlet and outlet joint; one end of the third air duct (10) is communicated with one joint of a second tee joint (9);the other end of the third air duct (10) is communicated with a bottom inlet and outlet joint; an air outlet of the cold air blower (13) is communicated with a fourth valve (8); one end of the fifth air duct (15) is communicated with a joint of a sixth valve (14), and the other end of the fifth air duct (15) is communicated with a hot air outlet of a heat exchanger of a hot blast heater. Because the thermal insulation sealed grain dryer is equipped with the air supply and exhaust interchange system, the defect that grains are non-uniformly dried is overcome.
