Wall surface ventilation device convenient for keeping indoor drying

Abstract

The invention relates to a wall surface ventilation device convenient for keeping indoor drying. The wall surface ventilation device comprises an intake fan and an exhaust fan which are arranged on the wall surfaces of a barn; the intake fan is arranged at the position, away from the ground surface, of any wall surface; the exhaust fan is arranged at the position, close to the ground surface, of the opposite wall surface of the intake fan; the opening and closing of the intake fan and the exhaust fan are controlled by an electromagnetic valve; the electromagnetic valve is connected with a controller; the controller is connected with temperature sensors arranged inside and outside the barn; an air drying cylinder is arranged on an intake pipe of the intake fan; at least two layers of two-layer filter screens with a sandwich structure are arranged on the inner wall of the drying cylinder; a plurality of drying agents are uniformly arranged in the sandwich layer of the filter screen at intervals. Air entering the intake pipe passes through the drying cylinder, and the air can be well dried by the drying barrel, so that grains are prevented from being mildewed; moreover, the waste of energy consumption is avoided by intelligently controlling the intake fan and the exhaust fan.

Description

technical field [0001] The invention relates to the field of ventilation equipment, in particular to a wall ventilation device for keeping the room dry. Background technique [0002] Food is the material basis for human survival. Food issues are related to the development of society and the stability of people's lives. With the advancement of science and technology and the improvement of people's living standards, consumers are paying more and more attention to food quality and food safety. Different seasons and different regions produce different grains. Therefore, in order to ensure that there is no shortage of grains, it is necessary to store grains and carry out unified macro-control. However, grains are easy to produce under certain conditions, such as high temperature and high humidity Moldy, if not dealt with in time, the grain will easily go moldy and deteriorate; and the grain will also be damaged by insects, moldy grain, tasteless grain, and non-germinated seed gra...
