초록 ▼

The disclosure relates to an improved static mixing nozzle, suited particularly for use in systems for delivering viscous molten plastics, for injection molding and like processes, but useful to good advantage in the mixing of other flowable materials, dry, liquid and gaseous. The mixing nozzle includes a cylindrical, tubular nozzle housing having inlet connection means for coupling with a plastic extruder or the like and a discharge nozzle at the opposite end. Within the cylindrical housing is a mixing element in the form of a cylindrical plug. The plug is provided with a plurality of sets of through bores, which extend at an angle from one side wall to the other, passing through the center axis of the plug. There are several stages of such bores, and each stage includes a plurality of mutually intersecting bores, which meet at the central axis of the plug. Four such intersecting bores per stage, in a unit of around five or six stages, provide a highly advantageous and practical static mixing device for typical application. The device is characterized by extremely high mixing efficiency, while providing a low pressure drop.

A static mixing unit for mixing flowable materials, which comprises a. a substantially solid body having a longitudinal axis and provided with an inlet end and an outlet end, b. a plurality of flow passages formed in said body, c. a first plurality of said flow passages communicating with said inlet end and extending angularly to the outer surface of said body, d. each of said flow passages converging from said outer surface centrally through said body to said longitudinal axis whereby all of said flow passages intersect at a common area along the axis of said body, e. said flow passages diverging from said common area to said outer surface and reconverging and diverging to intersect at one or more additional common areas at the axis of said body to provide a plurality of series related mixing stages, and f. said flow passages communicating with the outlet end of said body. The method of mixing a stream of flowable materials comprising the steps of a. passing the stream through the inlet end of a static mixer, b. dividing the stream into a plurality of sub-streams, c. diverging the sub-streams outwardly away from a central axis extending in the direction of flow of the stream to the outer surface of said static mixer, d. thereafter converging the sub-streams toward said central axis until they intersect and blend in a common area at said axis, e. increasing the velocity of the flowing materials momentarily as said materials flow through said common area, f. repeating steps (b) through (d) until the stream is thoroughly mixed, and g. reuniting the sub-streams at the outlet end of said static mixer.
