Description

The invention relates to a mixing technique and can be used in static mixers, as well as in forced mixing devices for producing solutions, emulsions, suspensions, gas-liquid to gas mixtures, as well as for mixing bulk materials.

The aim of the invention is to simplify the assembly and enhance the reliability of the mixer body.

FIG. 1 shows the working body of the mixer, a general view of FIG. 2 is a view A of FIG. one; in fig. 3-4 - elements of the working organ in FIG. 5-7 - options for assembling elements.

The working body of the static mixer (Fig. 1) consists of three-blade mixing elements of the right 1 and left 2 winding blades. There is also a locking element 3, the hub of which is similar in design to the hub of the element. The set of mixing elements together with the fixing element is mounted on the rod 4 and compressed by nuts 5. The fixing element 4 is clamped in the flange connection of the pipeline 6. The set of mixing elements is freely supported on the internal surface of the pipeline 6. The mixed components are fed through the holes in the fixing element. The right element 1 is depicted in FIG. 2, left - in FIG. 3. The first six right-hand elements of the working body form uninterrupted right-handed surfaces, as shown in FIG. 4, followed by two left elements, set offset by 60 (dividing the angle in half), as shown in FIG. 5, then - two right elements h offset by 60; following de

the elements are similar to the previous one, but the opposite direction of winding. The last four elements are assembled with alternating windings and offset by 60 (Fig. 6). One end of the hub of each element is provided with a diametrical pin in the direction of the end face of one of the blades, the other - with a diametral groove in the direction of the opposite end face of any other blade.

The device works as follows.

With a stress on the leading edge of the first link, the stream splits into three streams and twists to the right. Then the technological stream enters the turbulent section, where there are series of elements arranged in a checkerboard pattern. There is an instant radial expansion of the process stream. In the subsequent sections, an alternate change in the direction of flow and its dispersion occur. A smaller flow separation is also provided. If in the first links the flow is divided into three jets, then the number of jets doubles.

The last section of the elements has a chopping effect and minimizes the formation of swirling flow, which allows you to maintain the maximum surface area of the dispersed phase for a long time.

Such a design of the working body of the static mixer allows highly efficient mixing of the components in the radial direction. The components pass through the mixer in exactly the same proportions in which they enter.
