Needle-barrel bonded plastic film connection interface siding underground granary

Abstract

The invention provides an underground grain bin with a syringe-bonded plastic film skirting on the connection interface. The internal surface of the grain bin is provided with a revetment interface. The ground revetment interface can be additionally provided with a protection layer or a functional layer, such as a wooden floor, to realize desired functions. The grain bin is characterized in that the revetment interface comprises a connection interface with a bonding interface, and a plastic film skirting. The connection interface is in bonded connection with the plastic film skirting. The plastic film skirting and the internal surface of the structure of the grain bin together form more than one enclosed space. The enclosed spaces are respectively connected with a negative pressure source. In Yangtze River Delta Area, the temperature of stored articles stored in the tube-sheet heat exchange type underground cooling grain bin is not more than 8 DEG C for the first summer with almost no energy dissipation. The inventory time of rice can be prolonged to eight years from the original two years. The underground grain bin also has the effects of negative-pressure vacuuming, drying, fight damaging, rice metabolism retarding and the like.

Description

technical field [0001] The invention relates to an underground granary for a needle cylinder bonded plastic film to connect an interface wall board. Background technique [0002] Existing grain warehouses are mostly built on the ground for moisture-proof purposes. In the Yangtze River Delta region, in summer, due to sunlight and far-infrared radiation from ground objects, the temperature of grain in the warehouse gradually rises to 30°C or even higher. Even if a lot of money is spent on installing air conditioners to cool down, due to the poor thermal conductivity of grains, it is difficult to cool down the inventory evenly, resulting in huge investment but little effect. After a summer, the free fatty acid parameters of rice have changed greatly, and the nutrition and taste have obviously deteriorated, and many of them are directly treated as aged grains. There have also been cases where grains were hydrolyzed and rotted due to the formation of condensation when the tempe...
