Neck element of disc filter sector and disc filter sector

摘要

A neck element of a disc filter sector and a disc filter sector. A sector (5) is provided with a blade part (11) having a filtering surface and a neck part (12) coupling the blade part to a disc filter (1). The neck part has an inner space through which liquid runs from the sector. The inner space of the neck part is provided with at least one support element (18) to prevent opposite flanks (19) defining the neck part from moving in relation to one another. The sector may comprise a separate neck element (20) that may be coupled to the blade part. In that case the neck element is provided with at least one inner support element.

1. A neck element of a disc filter sector, which is attachable to the disc filter sector to form its neck part, the neck element comprising:
a body having a first end, a second end, two opposite side edges, and two opposite flanks, the two opposite flanks joining the two opposite side edges, said body having a flat shape so that the surface area of the flanks is larger than the surface area of the two opposite side edges, the first end and the second end being separated relative to one another by a distance defining a length of the body; first coupling surfaces at a first end of the body for coupling the neck element to a blade part of the disc filter sector; second coupling surfaces at a second end of the body for coupling the neck element to a disc filter; a flow channel inside the neck element; wherein:
at least one support element is positioned inside the neck element and joining the flanks of the neck element;the at least one support element is positioned intermediate the first end and the second end of the body and has a length less than the length of the body;the at least one support element is an elongated rib; andone of the at least one support elements has a primary elongated rib axis aligned with a longitudinal axis of the neck element, said longitudinal axis extending through the first end and the second end of the body of the neck element.
