Description

A kind of grain drying storehouse, hidden air channel

Technical field

This utility model relates to belonging to agricultural machinery engineering, processing of farm products and storage engineering and grain and oil storage field of engineering technology. More specifically, this utility model relates to grain drying storehouse, a kind of hidden air channel.

Background technology

In agricultural production, food storage is an important step therein, if improper storage, grain can occur Go mouldy, insect pest, the plague of rats, degradation problem under grain quality, causes heavy economic losses to grain farmer, and grain security is country's war Slightly, thus grain storage, be dried, keeping link is all paid much attention to from peasant household to country.Farmer storage, past i.e. simple Being contained in sack, put indoor, have is also placed in cellar, it is impossible to ensureing to be dried ventilation etc., annual grain goes mouldy, the plague of rats Equal loss is huge, and self-built simple warehouse, peasant every household was commonly called as maize building later, and a kind of wood does, and can lead to by natural wind Wind, part solves precipitation and the problem such as go mouldy, but go mouldy, the problem such as the plague of rats still exists, grain loss is still serious, fire prevention Problem is the most more serious.The farmer scientific grain-storing bunker that country is promoting at present, this storehouse substantially solves grain natural drying, goes mouldy With problems such as the plagues of rats, get a good review in peasant household, improve the economic benefit of grain farmer, but be to ensure that for national food security Not, one is to be affected could not launch in current all peasant households by scientific grain-storing bunker price etc., and most peasant households remain Old-fashioned grain storage, even grain the most directly lie face down, scientific grain-storing bunker finite capacity, the sub-amount of storage in storehouse only enough single agriculture Family, even one family peasant household produces grain and all can not load.Two be single farmer storage be substantially exactly oneself produce grain, scale is relatively Little, it is unfavorable for state macro-control.So farmer storage also has many incomplete places.

Grain depot grain storage, country considers strategically, has built a lot of state-owned grain depot, has local provincial, also has and return central authorities straight Pipe, also have individual private, scale is bigger, is referred to as grain depot at this.The mean of storing grain of these grain depots, the past is mostly round Grain block of wood of shape, relatively simple and crude appearance fire hazardous, go mouldy simultaneously, the plague of rats etc. the most more serious.Used brick wall wood roof truss later Tile hanging roofing warehouse, part solve fire, go mouldy, the problem such as the plague of rats, but brick wall and wood roof truss are due to himself feature, brick wall It is not easy to bear the lateral pressure of grain, limited from stress and economically consideration bulk grain height, separately can not due to wood roof truss span Too big, from these two aspects, single holding capacity of bin is restricted, owing to wood roof truss impact is not fully solved warehouse fire safety problem.The nineties Since, rise concrete frame formula horizontal warehouse, architectural mainly have two kinds, is concrete post time in early days, prestressed concrete Earth house frame upper berth prestressed concrete plate structure, the later stage is concrete post mostly, light steel roof truss (or roof girder) colorful plate roof Structure, this framed bent formula horizontal warehouse is equipped with the process equipments such as ventilation again, substantially solve the grain plague of rats, go mouldy, fire prevention etc. is asked Topic, separately due to himself construction features, height and the span in warehouse are all greatly improved, and the depot storage capacity in single storehouse promotes the biggest.Institute It is the main flow of most grain depot grain storage with current this framed bent formula horizontal warehouse.From the above, it can be seen that grain storehouse building structure Form is continuously improving raising along with the development of society.

Currently along with the development of society, the raising of scientific and technological level, particularly a large amount of novel heat insulations are airtight waits Building wood The application of material, since 2000 particularly 2010, grain storage horizontal warehouse field occurs in that again the building structure of a kind of all steel Form, is referred to as awning storehouse at present.This warehouse cost is low, and construction speed is fast, environment friendly and pollution-free has the features such as fire prevention concurrently.From upper Face is told about it can be seen that along with social development, grain storage facility chamber storehouse is also being continually changing, is developing, according to this rule This novel awning storehouse can gradually replace framed bent formula horizontal warehouse becomes the main flow of modern grain depot grain storage equipment.

The features such as the design combines that this novel grain storage storehouse cost is low, construction speed is fast exactly, environment friendly and pollution-free and fire prevention, Air channel is carried out hidden design, is combined with air stove, reach to dry the purpose that storage combines.
