Abstract
The static mixing device includes a tubular casing and at least one mixing element composed of individual webs which are secured in the wall of the casing. The webs are disposed in crossing relation to each other with a transverse spacing therebetween. The terminal ends of each web are secured within the wall of the casing by being shrink-fitted, soldered, welded or threaded.
Claims13
A static mixing device for a viscous material comprising
- a tubular casing having a wall disposed along a longitudinal axis to define a flow path for the viscous material;
- and
- at least one mixing element disposed in and across said casing in said flow path, said mixing element including at least two webs disposed in crossing relation to each other and at an inclination to said longitudinal axis, each said web having a pair of terminal ends secured within said casing wall, said webs being transversely spaced from each other to define a space therebetween for passage of viscous material therethrough without hindrance.
A static mixing device for highly viscous melts comprising
- a tubular casing having a wall disposed along a longitudinal axis for a flow of a highly viscous melts therethrough;
- and
- a plurality of webs extending within and across said casing within a common cross-section of said casing for mixing of the melt passing thereover, at least one of said webs having a pair of terminal ends secured within said wall of said casing and at least two of said webs being disposed in spaced apart crossing relation to each other transversely of said axis to permit a flow of melt therebetween.
