摘要： Centrifugal apparatus for the continuous separation of solids-liquid mixtures and the internal washing of separated solids is provided with one or more conduits to deliver washing liquid into centrifugally sedimented solids tumbling and suspending these solids in washing liquid. A distal end of each wash conduit is positioned in close proximity to the inner surface of the centrifuge bowl near the conveyor blade which is adapted to contact the solids upon separation and propel separated solids toward the solids discharge port. The invention includes centrifugal apparatus provided with plurality of cutting tools such as knife blades adapted to cut and separate the sedimented solids. In another aspect of the invention centrifugal apparatus is provided with one or more dip weirs dividing the centrifugally separated liquid pool in the bowl into axially adjacent zones with suitable a passageway for transfer of liquids and solids between adjacent zones. In another aspect of the invention at least a portion of the leading surface of the conveyor blade is provided with an arcuate surface portion adjacent to the distal edge thereof of defined concavity in the leading surface and shape adapted to contact the sedimented solids and tumbling them in washing liquid. This invention provides improved separation of mother liquor from discharged solids and/or reduction of washing liquid required to achieve desired purity of recovered solid product.
摘要翻译：用于连续分离固体 - 液体混合物的离心装置和分离的固体的内部洗涤被提供有一个或多个管道以将洗涤液体输送到离心沉降的固体中，并将这些固体悬浮在洗涤液体中。每个洗涤管道的远端定位成靠近输送机叶片的离心机碗的内表面，其适于在分离时接触固体并将分离的固体推向固体排出口。本发明包括设置有多个切割工具的离心设备，例如适于切割和分离沉积的固体的刀片。在本发明的另一方面，离心设备设置有一个或多个浸渍堰将碗中的离心分离的液体池分成轴向相邻区域，其中适当的通道用于在相邻区域之间传送液体和固体。在本发明的另一方面，输送叶片的前表面的至少一部分设置有与前导表面中限定凹部的远端边缘相邻的弓形表面部分，并且适于接触沉淀的固体并将其翻转洗液。本发明提供改进的母液与排出的固体的分离和/或实现所需纯度的回收固体产物所需的洗涤液的还原。
