Technical field
The present invention relates to one kind ventilation, circulation pattern silo, belong to provisions room force ventilation field.
Background technology
Silo, vertical silo, brick dumpy silo, steel silo etc. (hereinafter referred to as silo) are that current world food industry is commonly used
Storehouse type, high with mechanization, automaticity, Bulk Grain can completely or partially flow automatically export, be usually used in major port, grain and add
Factory, logistic industry, as grain reserves storehouse type also very big application, it is small to be mainly characterized by floor space, for soil fund ratio
More rare area has very big advantage.But as the storehouse type of grain reserves, the silo such as silo also has its fatal weakness,
It is exactly that grain layer is especially high, there is the silo of different height from 20 meters to 50 meters.Grain layer is especially high, and the efficiency of force ventilation is very
Low, ventilation time is especially long, and the specific energy consumption of cooling is more than 1 times of horizontal warehouse, and substantial amounts of power consumption is wasted, Er Qieji
Originally there is no precipitation function, even the centrifugal fan cooling of most strength, also can only three meters of lower three meters of grain face and bottom have drop
The possibility of water, and the moisture at other positions does not have any change.Silo is also big to aerial stretching surface due to height, is subject to too
Positive width penetrates hot also strong, and the dangerous difference on upper strata is up to 10 meters or so, and southern area of China can be deeper, is easy to send out after grain is heated
Heat, and basic reason is that moisture is higher, silo cooling is all relatively difficult, and precipitation is just more difficult, and it is to be most difficult to keeping to cause silo
The storehouse type of grain, once and there is deep layer fever phenomenon in grain, be at all without any method processing, be all finally take grain out of a granary to sun it for
Final final result, huge loss is brought to enterprise and society.
