摘要： An emptying apparatus for removing the last contents of a silo includes an elevated floor supported by at least two support members above the bottom of the silo. The support members form at least one ventilating channel under the elevated floor. The elevated floor has a flat section for supporting at least two upper sheets, and at least one rib member disposed above the elevated floor and defining at least one emptying channel for emptying the contents of the silo. The flat section of the elevated floor has at least one transverse slit which connects the ventilating channel with the emptying channel. One of the upper sheets is disposed above the transverse slit and the flat section and overlaps another upper sheet to form a slit between them. The extent of overlap of the overlapping sheet is greater than the slide ramp of the silo product located to the right of the slit between the two sheets, such that the product particle cannot easily back up in the slit and drop through the transverse slit in the flat section to the ventilating channel below. An emptying spout connects the emptying channel to an evacuation duct which is disposed in a pressurized air distribution channel. The distribution channel is pressurized by a fan. Each of the upper sheets is of substantially trapezoidal shape and has along its wide base a downward lip and along its narrow base an upward lip, each lip being provided with oblong orifices. The total cross-sectional area of the oblong orifices is approximately one half the total cross-sectional area of the corresponding ventilating channel. The total cross-sectional area of the ventilating channel is approximately one half that of the ventilating exit. A plurality of ventilating channels and emptying channels can be provided.
摘要翻译：用于去除筒仓的最后内容物的排空装置包括由筒仓底部上的至少两个支撑构件支撑的高架地板。支撑构件在高架地板下方形成至少一个通风通道。高架地板具有平坦部分，用于支撑至少两个上部片材，以及至少一个肋部件，其布置在升高的地板之上并且限定至少一个排空通道以排空筒仓的内容物。高架地板的平坦部分具有至少一个将通风通道与排空通道连接的横向狭缝。上板之一设置在横向狭缝和平坦部分上方并与另一上板重叠以在它们之间形成狭缝。重叠片材的重叠程度大于位于两片之间狭缝右侧的料仓产品的滑动斜面，使得产品颗粒不能容易地在狭缝中备用并且通过横向狭缝落下平坦部分到下面的通风通道。排空喷口将排空通道连接到设置在加压空气分配通道中的抽空管道。分配通道由风扇加压。每个上部片材具有大致梯形的形状，并且沿其宽的基部具有向下的唇缘并且沿其窄的基部具有向上的唇缘，每个唇缘设置有长圆形孔。长圆形孔的总截面积约为相应通风通道总横截面面积的一半。通风通道的总截面积约为通风口出口的一半。可以提供多个通风通道和排空通道。
