Solar intelligent low-temperature grain storage system

Abstract

The invention discloses a solar intelligent low-temperature grain storage system. The solar intelligent low-temperature grain storage system comprises an intelligent control system, a small grain cooling fan and a grain storage warehouse used for stacking a grain pile, a solar panel assembly is fixedly installed on the outer surface of a roof of the grain storage warehouse through a supporting frame, the solar panel assembly is connected to an electric energy storage device, the electric energy storage device provides electric energy for the intelligent control system, and an overhead channelis formed between the solar panel assembly and the outer surface of the roof of the grain storage warehouse; a refrigerating pipe set composed of a plurality of refrigerating pipelines is vertically inserted into each of the two sides inside the grain pile, a plurality of air-permeable holes are uniformly formed in each refrigerating pipeline, the bottom ends of all the refrigerating pipelines ofthe refrigerating pipe set on one side are connected to the small grain cooling fan through communicating pipes, and the bottom ends of all the refrigerating pipelines of the refrigerating pipe set onthe other side communicate with the exterior of the grain storage warehouse through connecting pipes; and the upper surface of the grain pile is covered with a layer of plastic film in a sealed mode,and the plastic film is covered with a layer of heat insulation plate. According to the solar intelligent low-temperature grain storage system, links can be reduced, the cost is saved, and temperature-control and oxygen-control effects are good.

Description

technical field [0001] The invention relates to grain storage technology, in particular to a solar intelligent low-temperature grain storage system. Background technique [0002] At present, the main low-temperature and low-oxygen technologies used in grain storage are: (1) Use the low-temperature air in winter and use centrifugal fans to ventilate and cool; Use heat insulation materials to cover the grain piles on the grain surface, slow down the heat accumulation of the air on the grain surface and conduct heat exchange with two pairs of air convection, and use plates for heat insulation on the warehouse wall; use air conditioners to control the temperature of the warehouse in summer, and use fans to ventilate and cool down in winter , and repeat. (2) Using nitrogen-filled air conditioning technology and positive pressure airtight means to quickly reduce the oxygen concentration inside the grain pile to less than 2%, and maintain the level of hypoxia inside the grain pile...
