    • This invention relates to methods and apparatus for recovering abrasive for use with abrasive jet cutting systems. In one embodiment, an apparatus in accordance with the invention includes an abrasive-laden fluid handling device coupled to a catcher tank of an abrasive jet cutting system, a pre-classifier fluidly coupled to the abrasive-laden fluid handling device, a hydro-classifier fluidly coupled to the pre-classifier, a fine-particle separation tank fluidly coupled to a clarified-fluid flow outlet of the hydro-classifier, a wet abrasive receptacle positioned to receive a wet recovered abrasive discharged from the hydro-classifier, a de-watering device engageable with the wet recovered abrasive in wet abrasive receptacle, and a dryer unit. The abrasive-laden fluid handling device may include an abrasive-laden fluid conduit having a first end in fluid communication with the catcher tank and an abrasive-laden fluid outlet. Alternately, the abrasive-laden fluid handling device may include a fluid drive system. In another embodiment, a de-watering device includes a housing having a wet abrasive intake and a de-watered abrasive, and an eductor port situated along an abrasive travel path extending between the wet abrasive intake and the de-watered abrasive outlet, an eductor inlet coupled to the eductor port and coupleable to a source of eduction air, and a transport device. In a further embodiment, an apparatus includes an airflow control valve fluidly coupled to the eductor port and positionable in a first position to draw an entrained airflow from within the housing through the eductor port, and a second position to backflow the eduction air through the eductor port into the housing.
    • 本发明涉及用于回收用于磨料射流切割系统的磨料的方法和设备。 在一个实施例中,根据本发明的装置包括耦合到磨料喷射切割系统的捕集罐的磨料载流体处理装置,流体耦合到磨料载流体处理装置的预分级器,加氢分级器 流体耦合到预分类器,流体耦合到加氢分选机的澄清流体流出口的细颗粒分离罐,设置成接收从加氢分级器排出的湿回收磨料的湿磨料容器, 可在湿磨机容器中与湿回收的磨料接合的浇水装置和干燥器单元。 含磨料的流体处理装置可以包括具有磨料的流体导管,其具有与捕集罐和磨料填充的流体出口流体连通的第一端。 或者,含磨料的流体处理装置可以包括流体驱动系统。 在另一个实施例中,脱水装置包括具有湿磨料入口和脱水磨料的壳体,以及沿着在湿磨料入口和脱水磨料出口之间延伸的研磨行进路径设置的喷射器端口,喷射器 入口连接到喷射器端口并且可耦合到排出的空气源,以及输送装置。 在另一实施例中,一种装置包括流体耦合到喷射器端口的气流控制阀,并且可定位在第一位置,以便通过喷射器端口从壳体内抽出夹带的气流,以及第二位置,以使排出的空气通过喷射器 港口进入住房。
