Natural ventilated squat silo with double-layer cast-in-place roof

Abstract

The invention discloses a naturally ventilated squat silo with a double-layer cast-in-place roof. The naturally ventilated squat silo with the double-layer cast-in-place roof comprises a foundation, a silo body and a silo top cover, wherein the silo body is arranged on the foundation located underground; the silo top cover is located above the silo body; the silo top cover comprises an upper ring beam arranged at the top and a lower ring beam arranged at the bottom; a silo top roof sheathing is arranged between the upper ring beam and the lower ring beam; the roof sheathing comprises an upper-layer plate and a lower-layer plate located below the upper-layer plate; the upper-layer plate and the lower-layer plate are connected at an interval and form an empty space cavity; multiple air inlets are formed in the side wall of the bottom of the empty space cavity; multiple air outlets are correspondingly formed in the side wall of the top of the empty space cavity; and the air outlets are communicated with the air inlets. The squat silo roof is changed into two-time heat transfer, so that solar radiation heat is prevented from directly acting on the lower-layer plate of the roof; and solar radiation heat absorbed by the upper-layer plate and the lower-layer plate in contact with the air is transferred to the air and taken away along with the air by utilizing a hot-pressing effect of wind pressure, so that the heat insulation capacity of the roof is greatly improved, and the influence of an outdoor heat effect on grains in the silo is reduced.

Description

technical field [0001] The invention relates to the technical field of grain storage buildings, in particular to a naturally ventilated double-layer cast-in-place roof shallow round silo. Background technique [0002] The food issue has always been a top priority for the prosperity and development of a country and the stability of people's lives. Food security is an important cornerstone for maintaining world peace and security. my country is not only a country with a large population but also a powerhouse of food consumption. At the end of the 20th century, due to the increase in grain production, my country built large-scale grain storage. At present, the main forms of warehouses in China are divided into flat warehouses and shallow round warehouses. Traditional one-story warehouses not only occupy a large area, but also have poor grain storage performance and are prone to spoilage. [0003] CN110679302A discloses a self-drying type moisture-proof grain storage bin, whi...

Problems solved by technology

Dry the air inside the warehouse through the drying bag, but the drying bag is a consumable and may need to be replaced frequently, and frequent replacement needs to enter and exit the door, thus increasing the humidity or heat in the warehouse
