Abstract
The present invention relates to a static mixer (9) for installation in a fluid line, in particular exhaust line (5) of a combustion engine (1), with an annular body (10) comprising at least one blade row (11) with a plurality of guide blades (12) standing away from the annular body (10) to the inside. A cost-effective producibility is obtained when the annular body (10) in the circumferential direction (13) consists of at least two part bodies (14), when part bodies (14) adjacent in the circumferential direction (13) are fastened to one another and when each part body (14) comprises a plurality of guide blades (12).
Claims14
A static mixer for installation in an exhaust line of a combustion engine, with an annular body, comprising at least one blade row with a plurality of guide blades standing away from the annular body to an inside,
- wherein,
- the annular body defines an outer periphery of the static mixer and in a circumferential direction consists of at least two part bodies,
- part bodies adjacent in the circumferential direction are fastened to one another,
- each part body comprises a plurality of guide blades;
- wherein, the part bodies adjacent in the circumferential direction inter-engage into one another in a protrusion-receptacle configuration in a region of circumferential ends of the part bodies and are pressed together in the region of the circumferential ends with plastic deformation;
- and
- wherein, the part bodies adjacent in the circumferential direction are arranged in the circumferential direction abutting with their circumferential ends;
- wherein the region of circumferential ends is on the outer periphery;
- and
- wherein the plurality of guide blades are formed at an axial extent of the annular body and radially converge to a central region of the annular body.
A static mixer for installation in an exhaust line of a combustion engine the static mixer comprising:
- an annular body having an outer most annular wall defining an outer periphery of the static mixer and defined by at least two part bodies fastened to one another, each part body comprising at least one blade row with multiple guide blades standing away from the annular wall to an inside;
- wherein the part bodies each have circumferential ends;
- wherein adjacent part bodies engage one another in a protrusion-receptacle configuration and are pressed fit at their circumferential ends along the annular wall with plastic deformation;
- wherein the adjacent part bodies engage one another on the outer periphery;
- and
- wherein the multiple guide blades are formed at an axial extent of the annular body and radially converge to a central region of the annular body.
