Comprehensive grain storage system for house type granary

Abstract

The invention discloses a comprehensive grain storage system for a house type granary. The comprehensive grain storage system comprises a ventilation opening, a circulation pipeline and a gas adjustment pipeline, wherein the ventilation opening communicates with a bottom ground cage of the granary, the circulation pipeline communicates with a top space of a grain heap in the granary, and the gas adjustment pipeline communicates with the top space of the grain heap in the granary and is used for conveying inert gas; and a branch pipeline I and a branch pipeline II which are in parallel are connected between the ventilation opening and the circulation pipeline, an internal-circulating-flow blower, of which an air inlet communicates with the ventilation opening and an air outlet communicateswith the circulation pipeline, is arranged on the branch pipeline I, a fumigating blower, of which an air inlet communicates with the circulation pipeline and an air outlet communicates with the ventilation opening, is arranged on the branch pipeline II, the ventilation opening is further connected with a branch pipeline III, and an exhaust blower, of which an air inlet communicates with the ventilation opening and an air outlet communicates with the outside, is arranged on the branch pipeline III. According to the comprehensive grain storage system for the house type granary, integrated multiple functions are achieved, different functions can be switched flexibly, internal-circulating-flow temperature control, fumigation and gas adjustment storage can be performed independently, the quality of grain storage is guaranteed, and the system is simple in operation, convenient to install and maintain and low in running energy consumption.

Description

technical field [0001] The invention relates to the technical field of grain storage, in particular to a comprehensive grain storage system of a room type warehouse. Background technique [0002] Grain warehousing is the storage and management process of grain from harvest to consumption. Humidity and temperature are the key factors for the safety of grain storage. The traditional granary ventilation system adopts cage ventilation on the ground or floor trough ventilation. The vertical stratification of grain moisture is serious, and the grain piles in the granary tend to form large cold cores and obvious The temperature of the grain at the cold core of the grain pile can be kept below 15°C for a long time, and it can be stored safely for a long time, while the temperature of the grain at the top of the grain pile will reach 25°C-30°C, and the quality of the grain changes quickly and is easily affected. Insect and mildew hazards, accompanied by heat transfer, can cause loca...
