用于离心设备的颗粒状物质供给装置
摘要：
本发明公开了一种颗粒状物质供给装置，包括：至少一个颗粒状物质容器，所述颗粒状物质容器的底部设置有颗粒状物质供给口，被容纳于所述颗粒状物质容器中的颗粒状物质通过所述颗粒状物质供给口被向外供给；与颗粒状物质容器对应并与所述颗粒状物质容器固定的至少一个颗粒状物质端口开关单元，每个颗粒状物质端口开关单元包括：气缸，所述气缸内设置有活塞；以及控制杆，所述控制杆的一端连接至所述活塞，以在气缸的作用下控制所述颗粒状物质供给口的开闭。根据本发明的颗粒状物质供给装置，能够在离心模型试验过程中实现对颗粒状物质供给速率及流量的控制，并且系统简单，控制方便，成本低。
摘要（英）：

The invention discloses a granular material feeding device, which comprises at least one granular material container and at least one granular material port switching unit, wherein the bottom of the granular material container is provided with a granular material feeding hole, and the granular material accommodated in the granular material container is fed outwards through the granular material feeding hole; the at least one granular material port switching unit corresponds to and is fixed with the granular material container; each granular material port switching unit comprises a cylinder and a control rod, wherein a piston is arranged in the cylinder; and one end of the control rod is connected to the piston to control the opening and closing of the granular material feeding hole under the action of the cylinder. The granular material feeding device can realize control of granular material feeding rate and flow in a centrifugal model experiment process, and has the advantages of simple system, convenient control and low cost.
