Patent ID: 7040802

Claim:
A static mixer for a high-viscosity flowing fluid with mixing elements which are made as monoliths, with sleeve elements in the form of tube pieces by means of which the mixing elements are positioned, and with a housing into which the sleeve elements are inserted together with the mixing elements, with the mixing elements each including a lattice structure, webs of this lattice structure crossing at crossing positions which are arranged at bar-like region transversely to a main flow direction of the fluid, and the main flow direction being given by a longitudinal axis of the housing, characterised in that the sleeve elements are in contact at their ends via abutment surfaces; in that cut-outs exist at these ends into which two annular segments of the mixing elements are inserted in a shape-matched manner to the cut-outs; in that two end surfaces of each segment are each arranged such that centers of the end surfaces can each be connected by lines which are aligned at least approximately the same as the bar-like regions of the crossing positions; and in that these bar-like regions have cross-sectional surfaces which are not larger than radial cross-sectional surfaces of the ribs.
