Definitions
- This invention relates to the retention of filter elements, principally in
- retained particles on the filter cloth can be removed by scrapers or other
- Disc filters of this kind are commonly used in filtration of minerals
- Each filter disc may comprise 8 to 12
- a complete installation may comprise up to 200 filter wheels or more and the
- each wheel may occupy 2-3 workers to remove, dress and re-fit so that each wheel
- An object of the invention is to provide means for retention of filter
- apparatus comprises two or more adjacent filtration sections, there is
- the bead, or at least the lips of the grooves are of flexible
- the filtration apparatus is preferably a vertical disc filter of the kind
- the elongate member may have a hollow core, to enable a sector dividing stem to pass along the elongate member.
- the elongate member comprises an
- polypropylene polyethylene or polyamide or a blend of two or more thereof
- grooves may be provided at each side of the member to receive the edges
- the bead on each filter cloth edge is preferably an elastomeric
- extrusion of e.g. natural or synthetic rubber or the like, which can be
