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
The present invention relates to a kind of compound ventilation air-changing device, particularly relate to a kind of Multifunctional granary compound ventilation air-changing device.
Background technology
In the foodstuff preservation process, insect pest, mould evil, the plague of rats and other biohazard and Grain storage heating go mouldy grain is destroyed.According to statistics, the whole world accounts for 5% of gross storage capacity because of warehouse insect and the grain loss that causes that goes mouldy every year.Aeration-cooling, prevent that high temperature from going mouldy, preventing and treating the vital task that grain storage pest becomes the work of grain security storage.
The large-scale storehouse of the grain of China North China, northeast, the Northwest type mainly is large storehouse.Behind the general grain warehouse-in in autumn, need aeration-cooling, dehumidifying, can utilize natural cooling source aeration-cooling to greatest extent in late fall, winter and early spring, the grain temperature is reduced as far as possible, rely on the grain cold-storage.To spring, particularly summer, the temperature in the recycling low-temperature grain latent heat regulation and control silo is not higher than 20 ℃ in order to keep the grain temperature, reaches grain long term guarantee quality hoarding effect.Therefore, need aeration-cooling dehumidifying, the cold-storage that ventilates in late fall, winter and early spring, ventilation time to reach 3-5 month in early autumn, almost all want every day continuously or intermittent air blast cooling, ventilation or ventilation drying.
The ventilation system of large storehouse is: in the both sides of the long vertical side of warehouse far from ground about 1 meter eminence, 5～8 meters at every interval arranges an air inlet; , distance placed in the middle in wide vertical side pushed up approximately, and 1 meter eminence sets out the air port.At present, air inlet is generally uncovered, and the iron screen cloth that protection against rodents is used is installed in the part warehouse at the air inlet place, and axial-flow type air-exhausting machine is installed at the air outlet place.The iron screen cloth that protection against rodents is used is also installed at air outlet in indivedual warehouses.
Air inlet is generally hollow cylinder, adds the ventilating opening end cap of an insulation usefulness.When ventilation, ventilation, end cap is in open mode.Because air inlet is very near apart from ground, and night lighting light attract insect sometimes has flying insect, crawling insect, mouse, bird, snake etc. and enters into the silo cage from air inlet, even enter the grain heap.In addition, hollow cylinder can produce cold bridge for to make by metal material, and at conduction cooling and be easy to dewfall in summer, permanent use can be got rusty, and also can cause near the local grain temperature rise ventilating opening, grain moisture large, easily produces and goes mouldy, and causes unnecessary foodstuff preservation loss.
Summary of the invention
But the technical problem to be solved in the present invention provides a kind of protection against rodents, insect protected, anti-bird and can effectively prevent heat conducting silo Multifunction ventilated air interchanger.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
A kind of multi-functional grain depot compound ventilation air-changing device, comprise the hollow cylinder ventilating duct that consists of and the end cap that is arranged on port, the ventilating duct outside, it is characterized in that: described ventilating duct comprises cylindrical shell and the end cap that is arranged within the silo embedding wall, wherein, inside from described cylindrical shell external port, be arranged at intervals with successively repellent cyclome, mythimna separata ring, protective metal net and high-voltage fence.
Described cylindrical shell is made by the anti-aging polythene material.Be formed with groove on the described repellent cyclome, be provided with oil absorbent material in concave ring groove, described oil absorbent material is soaked with the repellent medicine that expelling parasite is used.Described repellent medicine is Folithion or the 4-methyl thiuram that is dissolved in polyvinyl alcohol, and concentration is 1-3%wt.
Described mythimna separata ring inboard caves inward and is formed with concave ring groove, is provided with adhesive sticker in described concave ring groove.The described concave ring groove degree of depth is 5-10mm, and wide is 20-30mm.
Described high-voltage fence is the high direct voltage electrical network, described high direct voltage electrical network and the insulation of described cylindrical shell.The sieve aperture of high direct voltage electrical network is of a size of 5mm * 5mm.
Multifunctional granary compound ventilation air-changing device of the present invention, because inside from the cylindrical shell external port, be arranged at intervals with successively repellent cyclome, mythimna separata ring, protective metal net and high-voltage fence, therefore can effectively stop the biologies of creeping, fly such as worm, mouse, bird, snake to enter silo, thereby greatly reduce the foodstuff preservation loss.The use of anti-aging heat-insulation and heat-preservation PE material can reduce the conduction of outside heat, thereby has avoided the generation of the mouldy phenomenon such as rot of the grain that caused by silo local heating.
