Definitions

  • the invention relates to a static mixer consisting of at least one Mixer insert, optionally a support and optionally a hold-down device, with an enclosing housing, the mixer insert consisting of a variety of nested grids, parallel to each other, one on top of the other lying layers arranged webs is composed and wherein the Grid against each other by an angle ⁇ around the main flow direction through the Mixers are arranged twisted.
  • a pump presses the liquid through static mixer internals provided pipe, the that of the main flow axis the following liquid is divided into partial flows, depending on the type of internals be swirled and mixed.
  • Kenics mixers With the so-called Kenics mixers (see “Mixing during manufacture and processing von Kunststoffe ", publisher VDI Ges. Kunststofftechnik, VDI publishing house 1986, pp. 238-241), the liquid flow of the mixed material is changed into a Pipe installed divider divided into partial flows. This divider is around that Tube axis twisted. A vortex-shaped flow arises in each of the partial flows, which leads to the redistribution of the liquid in the cross section of the tube. Usually several such mixing elements are arranged one behind the other to form the liquid to share again and again and to achieve a sufficient mixer result. A satisfactory mixture is typically only after 10 to 12 mixing elements reached.
  • SMX mixers consist of two or more mutually perpendicular grids of parallel Metal strips that are welded together at their crossing points and in are made at an angle to the main flow direction of the mix, in order to to divide and mix the liquid into partial flows.
  • the manufacturing effort for this mixer is very high because of the many welded joints to be made.
  • a single mixing element is unsuitable as a mixer because it only mixes takes place along a preferred direction transverse to the main flow direction. Therefore several mixing elements, which are rotated by 90 ° to each other, must be used one after the other to be ordered. Good mixing typically requires 5 to 6 mixer elements arranged one behind the other.
  • An SMX mixer only points two against each other grid of parallel webs rotated by 180 °. These grids consist of layers more equidistant Walkways. Adjacent layers are aligned. Any location represents a plane of symmetry that is not crossed when mixing.
  • the object of the invention is to provide a static mixer which the Mixing effect of the known mixer, especially the SMX mixer, exceeds and can be produced with a minimal manufacturing outlay.
  • a static mixer at least from a housing with possibly a support and possibly a hold-down and with a mixer insert consisting of at least three against each other parallel webs twisted around the direction of flow, leading to Flow direction are set.
  • the invention relates to a static mixer consisting of at least one Mixer insert, optionally a support and optionally a hold-down device, with an enclosing housing, the mixer insert consisting of at least three nested grids of parallel to each other, one on top of the other lying layers arranged webs is composed and wherein the Grid against each other by an angle ⁇ around the main flow direction through the Mixers are arranged twisted.
  • a preferred embodiment of the static mixer is characterized in that that the webs to the main flow direction through the mixer by an angle ⁇ preferably from 30 to 60 °.
  • the webs are a grid through the webs of the other grilles, the housing and the end webs fixed in position by the support and / or the hold-down device.
  • the number of grids in the mixer insert is preferably static Mixer three or four.
  • the static mixer is particularly preferably rotationally symmetrical the number of grids built up.
  • a preferred embodiment of the static mixer is characterized in that that three grids with parallel webs are built from parallel layers of webs are, with adjacent layers each sitting on a gap.
  • Another preferred embodiment of the static mixer is characterized in that that four grids with parallel webs are built from parallel layers of webs are, with adjacent layers aligned with each other.
  • adjacent lattice planes are of a grid is offset from each other and the number of grids is four.
  • the webs are designed as hollow webs which open into the housing wall, wherein the housing wall is a casing with feeds divided into several chambers and has derivatives for a heat transfer medium.
  • Another object of the invention is the use of the invention static mixer for mixing highly viscous mix, in particular Polymer melts or polymer solutions with additives, other polymers, Dyes, pigments or stabilizers.
  • a static mixer according to the invention is in a perspective View shown; the housing 1 is shown cut away.
  • Figure 4 shows a view along the webs of a grid. It can be seen that the Bars 2a, 2b, 2c through the bars 6a, 6b, 6c and 7a, 7b, 7c of the other grids in their Location are fixed. Bridges are only added in the top and bottom layers fixed by the support 3 or the hold-down device 4 (not shown in FIG. 4).
  • Figure 5 shows an arrangement of webs for a mixer insert with a square cross-section and with fourfold rotational symmetry of the webs to each other.
  • This mixer insert requires a housing 1 with a square cross section.
  • FIG. 6 shows a mixer / heat exchanger consisting of a Outer housing 10 and an inner housing 1, with nozzle 13 for the product supply and nozzle 14 for product removal, and a supply line 11 and a discharge line 12 for a temperature control medium. Walls between outer housing 10 and inner housing 1 divide the space into two chambers 15 and 16 for the supply and discharge of the heat transfer medium.
  • FIG. 9 shows the arrangement of the tubes Bars 17 inside the mixer / heat exchanger. It is marked by four grids with parallel webs, which are at 90 ° to each other Flow direction are arranged rotated.
  • a particularly narrow pipe arrangement is achieved in that adjacent grid levels of a grid are arranged offset from one another.
  • Figure 10 shows an alternative arrangement of the hollow webs of the mixer insert for a mixer / heat exchanger as shown in Example 4. Adjacent grid levels aligned with each other, the number of grids is four.
  • Such a mixer / heat exchanger is particularly suitable for 2-phase flows. Since the distance between the pipes across the flow direction is large compared to the distance in the main flow direction, there are large flow channels for the product. The arrangement of the tubes results in a flow in these flow channels Swirl flow with separation into a gas flow inside the channel and a liquid flow on the outside of the channel. This can cause pressure loss when Flow through such a mixer / heat exchanger can be kept small.
