立筒仓作为中转用仓型具有机械化程度高,出入仓快捷、方便的特点。但作为长期储备仓,在结构设计与附属设备上还存在许多不足,特别是没有通风系统,这对储备粮的安全管理产生一定的影响,因此,对立筒仓的机械通风亟需进行改造。实践证明,采取并联式卸料斗改造方式,不仅方式简单,成本低,效果好而且还具有一机多用,减少风机损耗等特点,为筒仓改造提供了一个成功的例证。 Silos as a transit warehouse with a high degree of mechanization, warehousing quick and easy features. However, as a long-term storage warehouse, there are still many deficiencies in structural design and ancillary equipment. In particular, there is no ventilation system, which has an impact on the safety management of grain reserves. Therefore, the mechanical ventilation of the silos needs to be reformed. Practice has proved that the parallel dumping hopper retrofit approach is not only simple, low cost, good effect but also has a multi-purpose machine, reducing fan losses and so on, for the silo transformation provides a successful example.
