Abstract

The invention discloses a layered ventilation method and a layered ventilation system for a grain store. Horizontal ventilation ducts are respectively arranged on the ground of the grain store and at the interior of a grain stack, a vertical air duct is arranged at a static pressure box to communicate two layers of air ducts to a ventilator outside the store so as to form the double-layer ventilation system, the grain stack is divided into a plurality of ventilation areas, and positive or negative layered ventilation operation is realized by combining conversion of air guide turnover plates, switching of an upper valve and air inlet and suction modes of the ventilator. Compared with a traditional ground cage trough ventilation system, the layered ventilation system has the advantages that: effective ventilation, moisture reduction, doubling of the height of the grain stack, good ventilation uniformity, basically no dead angle, high ventilation efficiency, simple and reasonable structure, low equipment cost, low energy consumption and capability of meeting the requirements of large bungalow stores for cooling grain stacks and drying in the stores.

Description

technical field [0001] The invention belongs to the technical fields of agricultural engineering, agricultural product processing and storage engineering and grain and oil storage engineering, and relates to a granary layered ventilation method and a system thereof. Background technique [0002] As the foundation of national security and national economy, food is an important strategic material related to the national economy, people's livelihood and national economic security. Maintaining the necessary national grain reserves is a necessary means to stabilize the grain market, and an important condition for ensuring people's basic livelihood, social prosperity, stability, and long-term sustainable development. In order to improve storage facilities, since 1998, the state has used 35 billion yuan of national debt funds to build a national grain reserve warehouse with a storage capacity of more than 63 billion kilograms nationwide, which has improved the grain storage conditi...
