  • Patent number: 8701896
    Abstract: 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, a circulating cleaning assembly is provided in the hydroclone region. In yet another aspect of the invention, improved hydroclone intake structures are described.

  • Patent number: 8689840
    Abstract: Agglomerated fine solids, e.g., agglomerated pellets (2B), that are located within a restricted space or pinch point of a conveyance system (1), and that impede the free-flow of fine solids from one vessel (4) to another vessel (10), are detected and fragmented through the coordinated use of a flow detector (12), breaker plate (8) and press (6). The flow detector (12) senses an interruption or diminishment in the flow of the fine solids and signals and actuates the press (6) which in turn engages and fragments the agglomeration. The breaker plate (8) is sized and configured to trap major agglomerates.
