US 9,248,386 B2 · Leaf filter system and replaceable filter leaf apparatus

Abstract

Filter and replaceable filter leaf apparatus are provided. The filter includes a housing defining a cavity having fluid inlet and outlet ports and a lid member with a manifold coupled to the outlet port and being adapted to conduct a fluid flow between the outlet port and a plurality of attachment areas. Replaceable filter leafs are selectively movable through an opening into the housing cavity and attachable with the manifold at the plurality of attachment areas. The replaceable filter leafs include a filter envelope consisting of a filter panel, a nozzle member on the filter panel and defining a passageway adjacent an opening in the filter envelope for conducting fluids therethrough. The nozzle member is selectively attachable onto the manifold of the polishing filter apparatus at any one of the plurality of attachment areas.

A method of connecting a filter leaf apparatus with an associated filter system, the filter system comprising a housing having a cavity with fluid inlet and outlet ports for conducting a flow of fluids into and out from the housing and having a manifold coupled to the outlet port, the filter leaf apparatus comprising a filter media disposed around a substantially planar drainage structure that permits flow of fluid in the plane of said structure and a nozzle adapter member operatively sealed with the media and in operative fluid communication with the drainage structure and defining an elongate passageway for conducting fluids in a first direction therethrough, the method comprising:

slidably connecting a connection portion of the nozzle adapter member with the manifold of the associated filter system;
and,
sealing a substantially planar sealing margin surface in the connection portion of the nozzle adapter member surrounding an outlet of the elongate passageway with the manifold by a compressive sealing force generated by the slidably connecting of the connection portion of the nozzle adapter member with the manifold, the compressive sealing force being directed along a sealing axis perpendicular to the plane of the sealing margin surface.
