    • A subterranean debris catcher takes in debris laden fluid at a lower end. The inlet flow is induced with an eductor whose discharge goes around the housing to the lower end inlet for the debris. The eductor suction induces flow into the lower end of the housing as well. Incoming debris goes up an annular space around the collection receptacle and turns to pass through a bladed wheel that imparts a spin to the flowing stream. The flow direction reverses from up before the wheel to down through a tube after the wheel. The solids are flung to the tube periphery and the fluid reverses direction to go back up to a screen before reaching the eductor suction connection. The debris swirls down an open bottom tube and is collected in a housing surrounding the down tube.
    • 地下碎片捕手在较低端摄入含有碎屑的液体。 入口流动由喷射器引起,喷射器的排放物绕壳体流到碎屑的下端入口。 喷射器抽吸也引起流入壳体的下端。 进入的碎屑向上收集收集容器周围的环形空间,并转过来通过一个向流动流转动的叶片轮。 流动方向从车轮向上反转,通过车轮后的管道反转。 固体被溅到管周边,并且在达到喷射器吸入连接之前,流体反转方向返回到屏幕。 碎屑在开放的底部管道下旋转并收集在围绕下管的壳体中。
