STATIC MIXER TUBE WITH INTERNAL TRIANGULAR ELEMENT APPROXIMATIONS TO HELICES

摘要

ABSTRACT OF THE DISCLOSUREA device for mixing flowable materials, especiallyrelatively viscous liquids and flowable solids, comprises apipe or tube section, preferably of circular cross section, pro-vided internally with at least one mixing element helicallytwisted in a uniform manner about the axis of the pipe and form-ed with only two groups of surface regions which are foldedrelative to one another and which alternate along the mixing el-ement. Each of these surface regions is of flat triangular out-line with a base of the triangle formed along one of the helical-ly twisted longitudinal edges of the mixing element and converg-ing toward the other. The flat surface regions may be truncated,i.e. of generally trapezoidal outlint with their narrow triangleside lying along the opposite edge of the mixing element fromthat occupied by the base, or of a pointed configuration wherethe triangle apex lies along this opposite side of the mixingelement.
