Definitions

  • the invention relates to a static mixer according to the preamble of claim 1.
  • EP 0 749 776 A1 describes a static mixer with a plurality of successively arranged, each identical elements, on each of which an entrance-side divider and an exit-side divider is formed. By means of the separating webs a symmetrical division and guidance of a medium flow in two or more partial flows is made possible.
  • a variation of the average residence time of an amount of substance in the mixer which has hitherto not been considered as a criterion, was used in order to achieve the highest possible tolerance to disturbances, in particular by pumping effects on a reactant side. Due to the different path lengths, a mixer according to the invention makes possible a particularly clear backmixing and, as a result, a high bandwidth or scattering of the average residence time in the mixer.
  • the shared media stream is offered at least two geometrically different lengths to a reunification or merge. This can also be considered as a temporal offset of the substreams prior to the merge.
  • a preferred embodiment of the invention in this case lacks a separating web, which is customary in the prior art and extends over the entire width of the channel, for dividing the media flow the entire cross section.
  • a congruence rotational or mirror symmetry
  • the mean path lengths differ by at least about 10%, more preferably by at least about 20%. As a result, a particularly good backmixing is achieved.
  • the mixing member has a base plate, wherein the base plate has at least one opening.
  • a deflection element is preferably arranged which has a wall section which extends predominantly transversely to the main direction. In this way, a division of the partial flows take place in that a first part of the accumulated on the deflecting medium flow diverges through the opening in the base plate and another part escapes around the deflecting member.
  • the deflecting element also has a predominantly parallel Having to the main direction extending wall portion.
  • the wall section which is predominantly parallel to the main direction, at least partially overlaps the opening, so that the wall section protrudes next to the opening and has a particularly effective effect on the splitting and deflection of the media flow.
  • a respective deflection member extends only on one of two opposite sides of the base plate.
  • the base plate has a left and a right half transverse to the main direction, wherein the at least one opening is located substantially on only one of the halves.
  • two openings in the main direction are particularly preferably arranged on the same half of the base plate directly one behind the other.
  • a first deflection structure is arranged immediately after the first of the two openings and extends on one of two opposite sides of the base plate, wherein a second deflection structure is arranged immediately after the second of the two openings and extends on the other of the two opposite sides.
  • the channel may have a substantially rectangular, in particular square, cross section or also a substantially round, in particular circular, cross section.
  • the mixing member is formed as a unitary component of material, in particular casting.
  • the material of the mixing member and / or channel may be plastic or metal, e.g. Be aluminum.
  • the static mixer has a total of only one integral mixing member.
  • several of the mixing elements may also be arranged one behind the other in order to further improve the mixture.
  • the mixing member by means of a single-opening mold, in particular plastic injection mold, can be produced.
  • the in Fig. 1 shown static mixer is presently designed as a hand-held disposable mixer from the field of construction chemistry. But it can also be a reusable type with other application area.
  • a in cross-section (see Fig. 3 ) rectangular channel 1 extends in a main direction X and surrounds a mixer volume, which is located between a feed region 2 and an outlet region 3 for a conveyed through the channel 1 media stream.
  • a mixing member 4 is arranged, which is circumferentially from the inner wall of the channel 1.
  • the mixer member 4 has a base plate 5 extending in the longitudinal direction X and a transverse direction Y, in which a plurality of openings 6 are arranged. Through the openings 6, the medium can pass from one side of the base plate to the opposite side of the base plate.
  • the base plate has a left half 5a and a right half 5b transversely to a central axis extending in the main direction X of the base plate 5.
  • Each of the openings 6 is arranged only on one of the halves 5a, 5b. In the transverse direction Y is located next to one of the openings 6 each have no opening.
  • the openings in the present case have a square, uniform in all directions expansion.
  • two of the openings 6 are arranged directly behind one another in the main direction.
  • a deflection structure 7 Starting from each of the openings 6 extends a deflection structure 7, starting from the base plate 5 perpendicular to this and only on one of the two sides of the base plate.
  • Each of the deflection structures 7 assigned to an opening 6 comprises a transversely extending wall section 7a immediately downstream of the opening 6.
  • the deflection structure has a wall section 7b running parallel to the main direction on the central axis of the base plate, projecting in the transverse direction Y at least partially covered with the opening 6.
  • the media flow is blocked by a deflecting 7.
  • a first partial flow deviates by the opening assigned to the deflection member 7 on the other side of the base plate 5.
  • the remaining part of the flow circulates the wall portion 7b parallel to the main direction and deviates from the other half of the same side of the base plate 5, being returned to the original half after the deflection structure 7.
  • Fig. 2 shows, by way of example, two paths W1, W2 of a media flow, which first flows through a first of two directly successive orifices 6 prior to its division, wherein it deviates from a deflecting structure located behind the opening 6.
  • the upper side of the base plate then takes place as described above, the division into two partial streams.
  • the opening 6 and its deflection structure 7 therefore together form a structure dividing the medium flow.
  • the first partial flow W1 circumscribes the deflection structure 7 extending on the upper side.
  • the second partial flow W2 passes through the immediately following opening 6 again through the base plate on its underside.
  • the partial flows are at least partially recombined at an opening 6. Obviously, the partial flows have different lengths W1, W2 behind him.
  • the openings and deflecting structures are dimensioned so that the division into two partial flows takes place at least approximately uniformly. A certain imbalance in the pitch may be desired due to the different path lengths.
  • Fig. 3 shows a schematic cross section through the channel 1, which has a square shape. It can be seen that the static mixer of this embodiment is divided in cross section into four sectors, which result from the separation into an upper and lower side and a left and a right half of the base plate 5.
  • Fig. 4 shows a modification of the example Fig. 1 to Fig. 3 in which the channel has a circular cross-section.
  • the channel 1 may also have a different cross-sectional shape.
  • the deflecting structures are flush with the channel wall to prevent escape of the medium along the channel wall.
  • the base plate 5 need not form an accurate plane as shown in the examples, but may also be slightly curved, coiled or the like.
  • the invention is not limited to the precise shapes of the elements according to the preceding embodiments.
  • the walls 7a, 7b of the deflection structures do not have to run straight and / or stand at right angles to one another. Even a flowing, curved shape or other angles are possible.
