摘要： A variety of improved hydroclone based fluid filtering systems are described. The hydroclones generally include a tank having an internal chamber and a filter (preferably a surface filter) that is positioned within the internal chamber. The filter defines a filtered fluid chamber within the internal chamber of the tank. The hydroclone may be operated such that a vortex of flowing fluid is formed between the chamber wall and the filter with the filter being located in the center of the vortex. With this arrangement, the filter acts as a cross-flow filter. In one aspect of the invention, the filter is a stepped filter. In another aspect of the invention, the filter is an surface filter, as for example, an electroformed metal surface filter. In some preferred embodiments, the openings in the filter are arranged as slots that extend substantially vertically so that they are oriented substantially perpendicular to the flow path of fluid flowing in the adjacent portion of the vortex. In another aspect of the invention, a circulating cleaning assembly is provided in the hydroclone region. The cleaning assembly is arranged to help clean the filter and is driven by the vortex of flowing fluid formed in the hydroclone region of the internal chamber. In yet another aspect of the invention, improved hydroclone intake structures are described. The described hydroclones may be used to filter water and other fluids in a wide variety of applications.
摘要翻译： 描述了各种改进的基于水力旋流器的流体过滤系统。 水力旋流器通常包括具有内部腔室和位于内部腔室内的过滤器（优选地是表面过滤器）的罐。 过滤器在罐的内部室内限定了过滤的流体室。 可以操作水力旋流器，使得在室壁和过滤器之间形成流动流体的涡流，并且过滤器位于涡流的中心。 通过这种布置，过滤器用作交叉流过滤器。 在本发明的一个方面，过滤器是阶梯式过滤器。 在本发明的另一方面，过滤器是表面过滤器，例如电铸金属表面过滤器。 在一些优选实施例中，过滤器中的开口被布置为基本上垂直延伸的槽，使得它们基本上垂直于在涡流的相邻部分中流动的流体的流动路径定向。 在本发明的另一方面，循环清洗组件设置在水力旋流器区域中。 清洁组件被布置成帮助清洁过滤器并且由内腔的水力旋流器区域中形成的流动流体的涡流驱动。 在本发明的另一方面，描述了改进的水力旋流器进气结构。 所描述的水力旋流器可用于在各种应用中过滤水和其它流体。
