Example Embodiment

[0016] The structure of the multifunctional granary ventilation device of the present invention will be described below with reference to the drawings and specific embodiments.

[0017] First as figure 1 As shown, the ventilation device includes a ventilation duct 1 and an end cover 2 arranged at an outer port of the ventilation duct 1. In this embodiment, the end cover 2 is a heat preservation window protruding outward by 50 mm. A flange connection is adopted between the end cover 2 and the port, and a rubber pad is added between the end cover 2 and the port. The ventilation duct 1 is a hollow cylinder that penetrates the inner insulation layer 7 and the wall 8 of the granary wall, and is made of anti-aging polyethylene (PE) plastic. In this embodiment, the total length of the ventilation duct 1 is 550mm, and the cylinder inner diameter is 500mm , The outer diameter is 550mm.

[0018] In the ventilation duct 1, the repellent medicine ring 3, the armyworm ring 4, the screen 5 and...

Abstract

The invention discloses a multifunctional grain depot ventilating device which comprises a ventilating duct formed by a hollow barrel and an end cover arranged at the position of a port positioned on the outer side of the ventilating duct. The ventilating duct comprises the barrel and the end cover, wherein the barrel is arranged in a grain depot and embedded in a wall. An expelling chemical ring, an insect adhering ring, a protecting metal net and a high-voltage power grid are sequentially arranged at intervals from the outer port of the barrel to the inside. The multifunctional grain depot ventilating device can effectively prevent reptiles, winged insects, birds and mice and the like from invading the grain depot, conduction of external heat can be reduced by using an anti-aging thermal insulation PE material, and accordingly grain mildew rot and the like caused by partial heating of grains can be avoided.

Description

technical field [0001] The invention relates to a ventilation device, in particular to a multifunctional granary ventilation device. Background technique [0002] In the process of grain storage, insect pests, mildew, rodents and other biological hazards, as well as heat and mildew in grain piles, will destroy grain. According to statistics, the world's annual grain loss due to storage pests and mildew accounts for about 5% of the total storage. Ventilation and cooling, prevention of high temperature mildew, and prevention and control of stored grain pests have become an important task in the safe storage of grain. [0003] The large-scale grain warehouses in North China, Northeast my country, and Northwest China are mainly tall and large one-story warehouses. Generally, after grain is stored in autumn, ventilation, cooling and dehumidification are required. In late autumn, winter and early spring, natural cooling sources can be used to maximize ventilation and cooling, so...
