Abstract
The present invention relates to a static mixer for generating a substantially homogeneous media stream. The mixer has a series of angularly offset mixing elements with each element comprising a central boss portion, a plurality of ribs extending radially from the boss and defining with the periphery of the boss a plurality of substantially pie-shaped segments through which the media stream flows, and a plurality of webs for dividing each segment into two substantially equal flow areas. Each web has a first edge extending substantially radially and a second edge extending substantially circumferentially and is twisted through approximately 90.degree. from the first edge to the second edge.
Claims14
A static mixer for generating a substantially homogeneous media stream which comprises:
- at least one compact mixing element for separating an incoming media stream into a plurality of layers;
- each said mixing element having a central boss and a plurality of substantially planar ribs extending radially from said boss;
- said ribs being spaced substantially equally about the periphery of said boss and defining with the periphery of the boss a plurality of substantially pie-shaped segments through which said media stream flows;
- and
- means for dividing each said segment into two substantially equal flow areas so as to provide improved mixing of said media stream as it passes through said mixer.
A compact mixing element for separating a media stream into a plurality of striations which comprises:
- a central boss;
- a plurality of substantially planar ribs extending radially from said boss;
- said ribs being spaced substantially equally about the periphery of the boss and defining with the periphery of the boss a plurality of substantially pie-shaped segments through which said media stream flows;
- and
- a plurality of webs for dividing each said segment into substantially equal flow subsegments, each said web being formed by a number twisted through approximately 90.degree. of rotation.
