美国Carter-Day Co.设计制造了一种利用空气袋原理排空流动性物料(如谷物、面粉、砂糖、盐、豆粉以及肉粉等)的自动气袋排空料仓(该公司称之为All-Flow System)。如附图所示,料仓内壁衬有可充气的薄膜,当需要卸料时,控制系统使薄膜充气膨胀,将物料挤向卸料口,可以克服挂壁、搭桥、孔穴和结块等问题,保证不间断地卸料。对绝大多数物料而言,其清仓率可达
Carter-Day Co. of the United States designed and manufactured an automatic airbag evacuation silo that uses the airbag principle to empty liquid materials such as grains, flour, sugar, salt, soy flour and meat powder, which the company calls All-Flow System). As shown in the drawing, the inner wall of the silo is lined with an inflatable membrane. When the system needs to be unloaded, the control system inflates the membrane and squeezes the material toward the discharging opening to overcome the problems of hanging, bridging, cavities and caking , To ensure uninterrupted discharge. For the vast majority of materials, its clearance rate up
