Technical Field

The utility model relates to the technical field of granary circulation, in particular to a gating device suitable for granary circulation air regulation.

Background

The granary circulation air regulation refers to a technology for controlling factors such as temperature, moisture and the like in a grain pile by using a circulation fan to circulate and ventilate and eliminate living environment of a mildew area in the grain pile. The circulating air flow of the granary is used for ventilation operation by a circulating fan, the circulating ventilation air flow can remove the too high oxygen content in the grain pile and gradually increase the concentration of carbon dioxide, thereby controlling and killing the growth and propagation of pests and mould, achieving the purposes of maintaining the grain quality and prolonging the storage life, and ensuring the high quality and safe use of the grain. In practice, the granary circulation flow air-conditioning device has a very wide application range, and can be used for storing various grain crops such as rice, wheat, corn, mung bean and the like. A gating device is a device in an electrical system that is used primarily to change the connection of electrical circuits so that electrical equipment switches from one circuit to another while achieving the effect of breaking a faulty circuit. A plurality of monitoring points are arranged in a general granary, gating can be carried out one by one through a gating device, an air pump is started to carry out insect suction, air suction and sampling analysis, whether window opening, ventilation, dehumidification, cooling, deinsectization and other measures are adopted or not is determined according to analysis results, and therefore the optimal environment conditions for safely storing grains in the granary can be always kept.
