Abstract

The invention discloses an inclined tunnel type grain dryer. The inclined tunnel type grain dryer comprises a frame support, a grain drying tunnel box body, a grain storage box, a grain discharging device, a plurality of upper air inlet and outlet connectors, a plurality of lower air inlet and outlet connectors and a plurality of air conveying pipes. The first air conveying pipe communicates with the first upper air inlet and outlet connector and the third upper air inlet and outlet connector. The second air conveying pipe communicates with the second upper air inlet and outlet connector. The third air conveying pipe communicates with the fourth upper air inlet and outlet connector and an air heat exchanger. The fourth air conveying pipe communicates with the fifth upper air inlet and outlet connector. The fifth air conveying pipe communicates with the first lower air inlet and outlet connector. The sixth air conveying pipe communicates with the second lower air inlet and outlet connector and the fourth lower air inlet and outlet connector. The seventh air conveying pipe communicates with the third lower air inlet and outlet connector. The eighth air conveying pipe communicates with the fifth lower air inlet and outlet connector and an air cooler. Through the inclined tunnel type grain dryer, resistance of hot air passing through grain layers can be greatly lowered; heat energy waste is greatly reduced, and the grain drying cost is greatly lowered; and the structure is simple, and the manufacturing cost is greatly lowered.

Description

technical field

[0001] The invention relates to an inclined tunnel type grain dryer, which comprises a frame support (1), a grain drying tunnel body (2), a grain storage box (3), a grain output device (4), several upper and lower Air inlet and outlet ports (E J ,E J โ€™), several air ducts (G i ). Background technique

[0002] At present, most of the grain drying in the world adopts a square vertical grain drying tower; The drying tower and the hot blast stove that provides the heat source for the drying tower. The drying tower is equipped with multiple grain storage sections, drying sections, slow recovery sections and cooling sections from top to bottom. The bottom of the drying tower has a grain discharge Section, the cooling section is composed of upper and lower sections, each cooling section includes two rows of intake angular boxes and exhaust angular boxes, and the number of exhaust angular boxes in each cooling section is also two The two rows of intake angular b...
