摘要： The disclosure, for classification, is to a pressure vessel with fill valve admitting thereinto material to drop into a perforate diaphragm to be transferred, vacuum pulling in the material upon the perforate membrane or diaphragm, to upstand thereabove, the gas plenum below the diaphragm having activating gas inlet valve means communicating therewith and opened at intervals temporarily to break the vacuum. When a batch of material has been drawn in, the fill valve and the vacuum (and air break) valves are automatically closed, the activating gas inlet valve is opened to admit activating gas, as compressed air, to pass upwardly through diaphragm and activate the material to a highly flowable state. A discharge valve is then opened to let the pressurized material flow out through a discharge line to point of transfer. As the pressure in material plenum drops, the discharge valve is closed, the activating gas valve is closed, and a purge valve in a by-pass line, around the discharge valve, is opened, and residual pressure purges the residual material as this pressure falls substantially to atmospheric, for a succeeding cycle to begin. The disclosure is also to pressure vessels where the material drops onto the diaphragm via gravity when the fill valve opens, such vessels also being mounted on load cells equipped to emanate a pressure signal in correspondence with the weight of material admitted into the pressure vessel. Also, the disclosure is to pressure vessels equipped with circuitry controlled drier apparatus. Additionally, for all forms, variations of circuitry are shown whereby various steps may be controlled by at least one of pressure, time, level probe position, weight and limit switch position.

摘要翻译： 用于分类的公开内容涉及一种具有填充阀的压力容器，其中进入材料以落入要传送的穿孔隔膜中，将穿孔膜或膜片上的材料真空拉动到其上方，隔膜下方的气室， 活化气体入口阀装置与其连通并暂时间隔开，以破坏真空。 当一批材料被吸入时，填充阀和真空（和空气断开）阀被自动关闭，致动气体入口阀打开以允许作为压缩空气的活化气体向上通过隔膜并激活 材料达到高度流动状态。 然后打开排出阀以使加压材料通过排出管线流出到转移点。 当材料通风室中的压力下降时，排放阀关闭，活塞气体阀关闭，排放阀周围的旁通管路中的净化阀打开，剩余压力清除剩余物料，因为该压力 大幅度下降到大气，继续开始。 本公开还涉及压力容器，其中当填充阀打开时材料通过重力滴落到膜片上，这样的容器也被安装在负载传感器上，负载传感器被配备成与进入压力容器的材料的重量相对应地发出压力信号。 此外，本公开是对装有电路控制的干燥装置的压力容器。 此外，对于所有形式，示出了电路的变化，由此可以通过压力，时间，水平探头位置，重量和限位开关位置中的至少一个来控​​制各种步骤。
