立筒仓作为中转用仓具有机械化程度高,出入仓快捷、方便.但作为长期储备仓,在结构设计上和设施上还存在许多不足,特别是没有通风系统,为保证储备安全,每年必须倒仓,不仅花费大量的电费,对机械设备也造成相当大的磨损,粮质也不同程度地遭到破坏,破碎粒严重增加,等级下降,综合经济效率低下.因此对立筒仓的机械通风改造迫在眉睫,而哈尔滨直属库由于仓容不足,立筒仓周转速度快,没有足够的空仓期进行通风系统改造,迫切需要实仓通风改造的可行办法,在实践中我们历经半年的试验探索,成功地研制通风和排粮转换装置,将整个装置通过筒仓排粮管打入筒仓内,带孔通风管达1.4 m~2.1 m,通风阻力非常小,甚至可以进行自然通风.将原筒仓顶部闲置多年的3千瓦离心进行改造,用在底部通风,粮面表观达到0.02 m/s,是平房仓降温最低速度0.01 m/s的2倍,单位通风量达到8.15 m3/h.t.试验成功后接着又将余下的同类型筒仓全部进行了改造,并进行了粮情通风处理,效果非常理想.

Vertical silo as a diversion in the warehouse has high mechanization degree, a levite was fast and convenient. But as a long-term ChuBeiCang in structure design and facilities also has many deficiencies, especially no ventilation system, in order to ensure the safety of reserves, each year must be applicable, spend a lot of electricity, not only is caused considerable wear and tear on machinery and equipment, food quality is also damaged in varying degrees, crushing grain of serious increase, the level drops, comprehensive economic inefficiency. Thus opposing silos of mechanical ventilation reform is eyebrow nimble, grain depot and Harbin due to storage, vertical silo flow speed, thereis not enough short positions period for the ventilation system transformation, an urgent need to solid warehouse feasible methods of ventilation reform, in practice we after half a year's experiment exploration, successfully developed ventilation and food conversion device, the entire unit in silo row LiangGuan into silo, perforated ventilation pipe up to 1.4 meters to 2.1 meters, the ventilation resistance is very small, even for natural ventilation. The original silos idle for years at the top of the 3 kw centrifugal, used in ventilation, at the bottom of the grain surface apparent at 0.02 m/s, is the warehouse temperature and minimum speed 0.01 m/s 2 times, unit ventilation rate is 8.15 m3 / h.t. After the success of the test then all the rest of the same type silo is reformed, and the grain situation ventilation treatment, the effect is very ideal.
