Modular Stacked Disc Filter Apparatus

摘要

A filter assembly and cage and/or capsule apparatus including upstream and downstream and optional intermediary supports having modified features to maximize fluid flow through the filter assembly. The cage apparatus has a plurality of posts with stacked ridges that function as cap engaging teeth. A cage end cap is formed with a plurality of slots corresponding in configuration and position to the plurality of posts. The combination of slots and ridges interact to create a locking mechanism to adjustably secure the end cap to the cage and to generate the necessary compression to seal the enclosed filter discs and supports. The upstream supports are formed with channels in an outer ring and optional channels in radially extending ribs to improve fluid ingress and transfer to the filter discs. The downstream supports are formed with channels or tunnels in an inner ring to facilitate filtrate egress into a filter assembly outlet.

主权项

1. A filter apparatus comprising:
a cage having portions defining a filter chamber, wherein the walls of the cage comprise a plurality of posts and rails that define slots, and wherein distal ends of at least two posts form stacked ridges on a surface of the post; a filter assembly secured in the container, wherein the filter assembly comprises a plurality of filter media discs, at least one upstream support and at least one downstream support compressed together; an end cap having portions defining slots corresponding in number to the plurality of posts, wherein the slots are dimensioned to engage the stacked ridges, and wherein the cap is secured to a top end of the cage; and, an outlet formed in the end cap, wherein portions of the downstream support are in fluid communication with the outlet.
