TECHNICAL FIELD
[0001] The utility model relates to ventilation and dehumidification technical field especially relates to a grain depot circulation type ventilation and dehumidification mechanism. BACKGROUND
[0002] In the grain storage industry, the grain depot has a core position for ensuring the safe storage and long-term supply of grain. With the continuous growth of grain output and the continuous expansion of storage scale, the precise regulation of the internal environment of the grain depot is increasingly critical. During grain storage, humidity conditions seriously affect the quality and storage period of grain. The environment of the grain depot is complex and changeable, affected by factors such as seasonal changes, geographical differences, and weather conditions, with frequent humidity fluctuations. For example, in the plum rain season, high humidity air from the outside can easily penetrate into the interior of the grain depot; in areas with large diurnal temperature differences, low night temperatures can easily cause water vapor to condense in the warehouse, causing humidity to rise sharply.
[0003] The traditional grain depot ventilation mechanism mainly consists of a warehouse body, a natural ventilation mechanism, and a mechanical ventilation mechanism. The working principle of this traditional grain depot is that the mechanical ventilation mechanism operates inside the warehouse body, using a fan and other equipment to make the air inside the warehouse flow, forming a convection, thereby achieving ventilation and air exchange for the grain, and promoting the exchange of moisture, heat, and other gases in the grain pile with outside air. In this process, the natural ventilation mechanism uses ventilation openings, ventilation windows, and other facilities to take advantage of the air pressure difference between the inside and outside of the warehouse and the natural flow characteristics of air to exhaust the exchanged air from the warehouse body.
[0004] The above prior art device lacks deficiencies and shortcomings. The traditional ventilation mechanism mainly focuses on air circulation, but lacks effective means for humidity control. In humid seasons and high-humidity environments, a large amount of water vapor from the outside can enter the warehouse during the ventilation process, and without dehumidification, this water vapor can only accumulate in the warehouse, causing the humidity in the warehouse to rise rapidly, exceeding the optimal humidity range for safe grain storage. This can easily cause problems such as grain mold and germination; and it is not effective in dealing with the condensation of water vapor caused by diurnal temperature differences. When the temperature drops at night, water vapor in the air inside the warehouse can condense into droplets on the surface of the grain pile and the warehouse wall, which can be reabsorbed by the grain, further increasing the moisture content of the grain. Therefore, a grain depot circulation type ventilation and dehumidification mechanism is proposed to solve the above problems. UTILITY MODEL CONTENTS
