Description

Thermal insulation airtight device for granary ventilation opening Technical Field The utility model relates to the technical field of granary ventilation, in particular to a heat-preservation airtight device for a granary ventilation opening. Background The low-temperature grain storage method is a grain storage method with great development prospect in the modern storage technology, so that the grain temperature is in a lower state, the low temperature can inhibit the respiration of grains, reduce the loss of dry matters, delay the aging of grains and the poor quality and speed, keep the freshness and the eating quality of grains, and achieve the aim of safe grain storage. However, in the process of summer, the temperature of the grain pile is affected by external high-temperature weather, the grain pile temperature is gradually increased under the influence of air temperature, the grain pile is affected by the structure of a granary, the surface layer and the bottom layer of the grain pile are in most contact with the outside, and the temperature in the area is increased most rapidly.
