Definitions

  • the invention relates to a static mixer for producing a material stream from two starting material streams with a housing, the housing having a, in particular cylindrical, main housing section, and a, in particular one-piece, mixing insert with at least one first helix.
  • Static mixers are characterized by the fact that they preferably have no moving parts and the material streams to be mixed have to be moved through them by means of a pump or similar.
  • Static mixers for example, are out of the document US 3,286,992 A known.
  • curved, plate-shaped elements are arranged one behind the other in a tube in a rotationally offset manner.
  • the mixing insert preferably has recesses into which the side bars engage.
  • a helix in the sense of the invention preferably describes surfaces wound around an axis, in particular helically wound, which have a slope in relation to a surface perpendicular to a longitudinal direction of the mixer. More preferably, the pitch of a helix can vary. A helix can have less than one revolution, exactly one revolution, more than one revolution or several revolutions.
  • a deflection element in the sense of the invention preferably describes surfaces that have a slope with respect to a surface perpendicular to a longitudinal direction of the mixer. More preferably, the deflection elements can be sections of a helix.
  • a mixing unit in the sense of the invention preferably describes a section of the mixing insert.
  • a double cartridge in the sense of the invention preferably describes a device with two separate containers, each of which contains a starting material. Further preferably, a double cartridge has a fastening mechanism for a mixer and an outlet opening for each container through which the starting materials can flow into the mixer.
  • a starting material stream in the sense of the invention describes material entering the mixer, preferably from a double cartridge.
  • the hardener and binder components can each represent starting material streams.
  • a material stream in the sense of the invention preferably describes the entirety of materials to be mixed or already partially mixed or completely mixed flowing through the mixer.
  • the invention is based on the knowledge that the best possible mixing of two fluids in a flow that is essentially laminar is achieved by dividing the flow into partial flows and combining them again as often as possible and by generating changes in direction and flow speed. This preferably creates local turbulence, which promotes mixing.
  • a helical mixing insert specifies a main flow direction, but the flow is divided by deflection elements, partially deflected in an opposite direction, and brought together again.
  • deflection elements When the flow flows around the deflection elements, local changes in the flow velocity also occur, which have a positive effect on the mixing.
  • a helical mixing insert specifies a main flow direction, but the flow is deflected by a side web projecting into the housing, in particular in the direction of the central axis. In addition to the change in direction, this also results in an advantageous change in the flow velocity in the area of the inner wall of the housing.
  • An advantage of the invention is the short mixer length, which is necessary to achieve a high degree of homogenization. This results in a further advantage of a small internal volume. This also means that the amount of material mixture that remains in the mixer after use is small.
  • Another advantage of the invention is the effective and efficient mixing of the material flows.
  • the mixer according to the invention it is achieved that all flow threads that pass through the mixer are mixed with neighboring flow threads, but are not mixed more than necessary.
  • Another advantage of the invention is the small number of individual parts to be assembled and an easy-to-use, securely sealing fastening mechanism in conjunction with the double cartridge.
  • the mixer according to the first aspect of the invention has a side web which runs in the longitudinal direction of the mixer and which projects into an interior of the housing, so that the material flow is deflected in the direction of a central axis of the mixer.
  • the mixer according to the second aspect of the invention has deflection elements which are in opposite directions to a screw direction of a first helix at the same height in the longitudinal direction of the mixer, the at least one first helix and one or more deflection elements being at the same height
  • the mixer which further refers to a mixer according to the first or second aspect of the invention, has a plurality of side webs, in particular two opposite side webs. This increases the housing rigidity and supports the mixing insert against deformation.
  • the side bars engage in recesses in the mixing insert.
  • the recesses of the mixing insert and the side webs of the housing are designed in such a way that the side webs at least essentially seal the recesses for a material to be mixed. By providing recesses, the mixing element can be pulled up to the housing.
  • the deflection elements are part of the mixing insert.
  • the mixing insert and the housing are preferably each formed in one piece. This has the advantage that the number of components is reduced and assembly is simplified.
  • the deflection elements are part of the housing and are in particular formed in one piece with the housing. This has the advantage that the number of components is reduced and assembly is simplified. There are also advantages in terms of the rigidity of the housing.
  • the deflection elements have a smaller outer radius than the at least one first helix, the outer radius being in particular approximately half as large as an outer radius of the at least one first helix.
  • the material flow in the area of the deflection elements is temporarily divided in approximately half, which is advantageous for effective mixing.
  • a gap is formed between the deflection elements and the at least one first helix, the deflection elements having an end face towards this recess which is designed to separate the material flow.
  • a surface which is formed by the at least one first helix and a surface which is formed by the respective opposing deflection element at the same height in the longitudinal direction of the mixer lie at least essentially in one plane. This reduces the geometric complexity, which is particularly advantageous in terms of manufacturing.
  • the first coils and deflection elements have reinforcing webs which are essentially parallel in a plane are arranged in a longitudinal direction of the mixer.
  • the reinforcing webs are connected to one another in a longitudinal direction of the mixer. This results in further improved rigidity and strength of the mixer and manufacturing advantages.
  • the reinforcing webs are arranged in a zigzag pattern and are designed in such a way that the cross section of a flow channel through the mixer in the area of the reinforcing webs is essentially trapezoidal. This results in improved mixing because the flow velocity is locally different in the radial direction due to the change in cross-section.
  • the mixer preferably its reinforcing webs, and/or side webs, is set up in such a way that the flow channel has cross-sectional changes in the flow direction, which bring about a change in the flow velocity of the material stream, and/or in particular the deflection elements and/or or the reinforcing webs are set up in such a way that the material stream is separated into several material streams and brought together again. This results in improved mixing.
  • the mixer is preferably designed, in particular its first coils, reinforcing webs, side webs and deflection elements, so that areas of local turbulence arise in the material flow.
  • the at least one first helix has between one revolution and approximately two revolutions, in particular exactly two revolutions. This results in an optimal ratio of mixer length and degree of homogenization.
  • the mixer has a first mixing unit and a second mixing unit, which are arranged one behind the other in the longitudinal direction of the mixer, the first helix of the first mixing unit and the first helix of the second mixing unit having an opposite winding direction. This has the effect of reversing the flow direction of the material stream and has a positive effect on mixing.
  • the mixer has a plurality of first and a plurality of second mixing units, which are each arranged one behind the other alternately in the longitudinal direction of the mixer. This reverses the direction of flow several times, which improves mixing.
  • a section of the at least one first helix which extends approximately over 90° and is arranged at one end of the at least one first helix, is a flow reversal element that is at least substantially perpendicular to the longitudinal axis of the mixer trains.
  • an end of the first helix of the second mixing unit, which faces the first mixing unit is preferably approximately 140° to 220° opposite an end of the first helix of the first mixing unit, which faces the second mixing unit approximately 180 °, offset with respect to a longitudinal axis of the mixer. This results in an additional space between the first coils, so that the material flow separates.
  • the deflection elements are sections of a second helix which runs in opposite directions to the respective first helix. This simplifies production.
  • the mixing insert, the deflection elements and the housing are set up and interact in such a way that a, in particular a single, flow channel is formed through the mixer.
  • the outer edges of the first coils each lie at least essentially sealingly against an inside of the housing for a material to be mixed.
  • the housing has a housing inlet section and the mixing insert has a mixing inlet section, the housing inlet section and the mixing inlet section being set up and interacting in such a way that a penetration depth of the mixing insert into the housing is limited by a mechanical stop. This simplifies assembly and use of the mixer.
  • the mixing inlet section preferably has a circumferential sealing edge which cooperates in a sealing manner with a circumferential recess in the housing inlet section. This ensures that the material to be mixed does not escape from the mixer, even at high internal pressures.
  • the mixing inlet section has at least two, in particular tapering, in particular cylindrical, inlet ports with continuous inlet channels. These enable secure installation on a suitable double cartridge and ensure a secure seal against the material to be mixed.
  • the mixing inlet section and the housing inlet section form a mixing anteroom into which the starting material streams enter through the inlet channels. This enables an advantageous calming of the flow and a uniform entry into the flow channel, which is formed by the mixing insert and the housing.
  • the inlet channels of the mixing inlet section are arranged so that they overlap with a projection of a cylinder enveloping the first coils onto a floor of the mixing antechamber. This enables a space-saving design of the mixer and a better flow to the at least one first helix and the deflection elements of the mixing insert.
  • the at least one first coil has a recess in a first coil surface in the direction of the material flow, and are in particular designed so that the inlet channels are not covered. This also contributes to a space-saving design of the mixer and a better flow to the at least one first helix and the deflection elements of the mixing insert.
  • the mixing inlet section of the mixing insert adjoins the first helix of the mixing unit adjoining the mixing inlet section and is in particular designed in one piece. This simplifies production.
  • the mixing inlet section has alignment means, in particular an eccentrically arranged web, on the side of the inlet port.

  • a mixing unit 7a, 7b preferably has approximately two revolutions, in particular exactly two revolutions, of the first helix 5.
  • Flow reversal elements 13 are preferably arranged between adjacent mixing units 7a, 7b. More preferably, the last quarter turn of the first helix 5 is formed by the flow reversal element 13.
  • a mixing unit 7a, 7b has deflection elements 6, which cause the material flow to be deflected in the opposite direction to the respective winding direction of the first helix 5. More preferably, a mixer 1 has eight mixing units 7a, 7b. Further preferably, mixing units 7a, 7b arranged one behind the other have an opposite winding direction of the first helix 5 in each case. In alternative embodiments, mixers 1 can have fewer than eight or more than eight mixing units 7a, 7b.
  • a beginning of a first helix 5 of a mixing unit adjacent to a flow reversal element 13 is offset by 180°. This causes a reversal of the flow direction of the material stream 25 (not shown) in the sense of the mixing unit 7a, 7b that is now to be flowed through.
