Description
Technical field
The utility model relates to a kind of grain steel silo, and particularly a kind of shape of cross section is the store grain metal heat preservation storehouse of bulk cargo of circular being used to.
Background technology
China is a large agricultural country, and along with scoring consecutive bumper harvests of agricultural production, the storage problem of grain also more and more obtains the great attention of governments at all levels.The silo structure that is used to store grain mainly is divided into two kinds of reinforced concrete silo and steel silos.Steel silo with respect to reinforced concrete silo have cost low, from advantage such as heavy and light, duration be short, reusable, along with keeping reforming of grain circulation system, the progressively popularization of (in bulk, load in bulk, loose and to unload, to loose storage) " scatters ", steel silo with transfer and storage function obtains application more and more widely.
Present steel silo great majority are individual layer thin-walled silos, do not establish insulation construction, its bulkhead is thin, the inside and outside easy formation temperature difference, be subjected to extraneous factor such as daylight, weather etc. influence big, dewfall phenomenon, grain stack temperature skewness weighing apparatus etc. are arranged, these factors are brought some difficulties to safe grain storage.
On February 23rd, 2005, notification number is the Chinese utility model patent of CN2680033, a kind of insulation metal storehouse is disclosed, comprise storehouse inner column and main bin plate, enclose on the main bin plate lateral surface and adorning the benzene plate, out barn plate is configured on the exterior face of benzene plate, utilizes the brill tail nail that has anti-leakage structure with fixedlying connected of storehouse inner column benzene plate and out barn plate to be packed on the main bin plate lateral surface in the lump, with its whole containing, its benzene plate is between main bin plate and out barn plate.In this insulation metal storehouse, the effect of out barn plate is that protection benzene plate does not come off and plays decoration function, thereby only is a kind of fender member, not bearing load.
On August 12nd, 1992, notification number is the Chinese utility model patent of CN2112607, a kind of double-walled insulation metal silo is disclosed, comprise storehouse in the metal, silo outside interior silo is outside equipped with, interior silo and outside expanded perlite is housed between the silo, be equipped with top board on the inside and outside warehouse, top board is provided with propeller fan air outlet and natural ventilation mouth, and warehouse is provided with door.The interior silo of this double-walled insulation metal silo is independent with outer silo, bears corresponding load respectively.
Also have a kind of steel structure double-walled insulation grain silo on the market, warehouse is the frame type steel work, and the storehouse plate is prefabricated high-strength compound plate, and the plate face is a color coated steel sheet, in establish insulation layer.The frame type steel work that this silo warehouse horizontal bar and perpendicular muscle form is born loads such as hoop tensile stress, and the bulkhead plate of silo only bears the lateral pressure that grain produces the bulkhead plate.
The utility model content
The technical problems to be solved in the utility model is, the metal heat preservation storehouse of the bulk cargo that is provided for storing grain has good airtight heat-insulating property, and inner panel and outside plate form common stress system and stressed clear and definite, and rolled steel dosage is few, easy construction.
