Abstract
A filter sector assembly for a disc filter, which disc filter has a fiber suspension containing bath and a core assembly adapted to rotate on a horizontal axis. The filter sector assemblies are rotatably supported with relation to the bath on the core assembly. The filter sector assemblies are spaced along the core assembly and supported on the core assembly. Each filter sector assembly (50) has two adjacent filter sectors (10A; 10B) releasably fixed to a bent support plate (30). The two adjacent filter sectors (10A; 10B) are attached as a pair of filter sectors (10A; 10B) by fastening the support plate (30) to the core assembly (21; 21A, 21B) of the disc filter.
Claims16
A filter sector assembly of a disc filter, which disc filter comprises a fiber suspension containing bath, a filter sector assembly rotatably supported with relation to the bath, a core assembly adapted to rotate on a horizontal axis, and a plurality of filter sectors spaced along the core assembly and supported on the core assembly, wherein the filter sector assembly comprises:
- a first filter sector connected to a support plate;
- a second filter sector connected to the support plate adjacent the first filter sector;
- and
- wherein the adjacent first filter sector and second filter sector comprise a pair of filter sectors attached by the support plate to the core assembly of the disc filter.
A disc filter comprising:
- a fiber suspension containing bath;
- a core assembly adapted to rotate on a horizontal axis, the core assembly having a plurality of planar outer surface parts, two of which plurality of planar outer surface parts being connected to each other at a first angle which is greater than 90 degrees;
- a first filter sector connected to a support plate;
- and
- a second filter sector connected to the support plate adjacent the first filter sector, wherein the adjacent first filter sector and second filter sector comprise a pair of filter sectors attached as a unit by the support plate to the two of the plurality of planar outer surface parts of the core assembly.
