In this case, the means for mixing on the one hand be part of the rotor element itself. Thus, the rotor element can have one or more mixing sections, at which the rotor element can be equipped with appropriate means for mixing, in particular wing elements. However, it may also be expedient to provide the means for mixing on a separate mixing element, in particular in the form of said vane elements, for example in one or more mixing sections, which is connected to the rotor element such that rotation of the rotor element results in rotation of the rotor element Mischelementes leads. The means for mixing can in particular be designed as the wing elements or mixing means of the rotor elements, which in the WO2012116883A1 , of the WO2012116863A1 , of the DE102004020410A1 or the DE20302987U1 are disclosed.

The dynamic mixing device according to the invention can on the one hand in a preferred embodiment be a dynamic mixer itself in such a way that all the features of the above basic idea are already implemented in the dynamic mixer. In an alternative embodiment, however, the dynamic mixing device according to the invention may be designed as an assembly and on the one hand comprise the dynamic mixer; on the other hand, while essential features of the above basic idea may be part of the dynamic mixing device, they may be detached and / or spatially separate from the dynamic mixer. In the application, however, there is at least one technical connection such that the detached and / or spatially separated features interact at least with parts of the dynamic mixer. In particular, it is conceivable that the designed as an assembly dynamic mixing device on the one hand provides a dynamic mixer, on the other hand, a structurally and / or spatially separate drive unit for the rotor element of the dynamic mixer, in particular the addition port for the addition of a propellant, via the propellant activatable rotating means, wherein in the application of the dynamic mixing device, so after bringing together the dynamic mixer and drive unit, an operative connection between the drive unit and the rotor element is present such that the rotor element is driven via the rotating means, therefore by means of the supply medium supplied via the feed opening for mixing the components is rotated.

In an alternative embodiment, therefore, another basic idea of the present invention is the provision of a drive unit for a dynamic mixer. In this case, the drive unit has connecting means for connecting a dynamic mixer to the drive unit, wherein in the mounted state of the drive unit and dynamic mixer said dynamic mixing device is provided.

The dynamic mixer to be connected further comprises means for mixing the components supplied via the inlet openings of the housing to the rotor element, said drive unit further comprising a coupling possibility for the rotor element to rotate the rotor element by means of the blowing medium supplied via the feed opening for mixing the components , Thus, for example, dynamic mixers already available on the market can be used in an inventive manner by the use of a drive unit according to the invention.

In the following, however, is the embodiment of a mixing device according to the invention in the embodiment as a dynamic mixer speech, the features and in particular the advantageous embodiments are also applicable to mixing device according to the invention as an assembly transferable in which essential features of the idea - as described above - detached and / or spatially separated dynamic mixer

According to the invention, it is provided for the drive and in particular the rotation of the rotor element for mixing the components and for providing the mixture to use a propellant, in particular a liquid or gaseous propellant. The propellant is in this case supplied to the dynamic mixing device via a separate from the inlet orifices feed opening. In this case, in a preferred embodiment, the addition opening may be part of the housing of the mixer itself. However, it is also possible that the addition port is spatially separated from the mixer and in particular from its housing. In the case of a multi-part housing, it can prove to be advantageous if the addition opening is provided on the part of the housing on which at least one inlet opening is provided for one or all components. Wherein in this case the discharge opening for the mixture is preferably provided on a further housing part. Further, an activatable via the driving medium, in particular movable or about an axis of rotation, preferably about the axis of rotation of the rotor member or rotatable parallel thereto rotating means is provided to drive the rotor element by means of the supply opening via the feed medium for mixing the components and in particular to rotate. Preferably, at least one channel and / or a working space is provided for the driving medium, which spatially separates the driving medium from the components and allows contact of the driving medium with at least parts of the rotating means to ensure a drive of the rotating means by a flow of the driving medium. In this case, the rotating means may be part of the rotor body itself, so that the rotor body is driven directly by the driving medium. For this purpose, the rotor body may be provided with blades or vanes with which the driving medium can come into contact so that the rotor body can be driven by the latter through the flow of the driving medium. Of course, it is also conceivable to use a rotating means, which is designed in the form of a rotary body as a separate component separated from the rotor body and is connected via an operative connection, in particular via a transmission and possibly additionally a clutch to the rotor body that a drive and in particular a Rotation of the rotary body allows a drive and in particular a rotation of the rotor body. For this purpose, the rotary body can be equipped with blades or vanes with which the driving medium can come into contact, so that the rotary body can be driven by the flow of the driving medium and in particular rotatable.

The dynamic mixer according to the invention is preferably made of plastic and designed as a disposable part. After use and concomitant mixing of the components into a mixture, the dynamic mixer is preferably disposed of. Of course, constructions are also conceivable in which a cleaning is possible, so that the mixer is reusable. Preferably, the dynamic mixer is designed such that the rotor body is accessible for cleaning or for cleaning or replacement can be removed. Additionally or alternatively, an at least partial design of the mixer of a metallic or ceramic material may prove to be useful.

As mixtures to be dispensed, preferably consisting of at least two components, in particular flowable to pasty mixtures are conceivable as they are used as sealants or adhesives in vehicle, ship and aircraft or in related repair and maintenance operations. For example, the multicomponent mixture may be an adhesive and / or sealant known in the aftermarket and / or series production of the motor vehicle sector and / or a sound and / or vibration damping material. Such adhesives and / or sealants or said materials may be liquid, viscous or highly viscous or pasty. However, such a multicomponent mixture may in particular also be a sealant processed in the construction industry, an adhesive and / or a surface coating. In addition, multicomponent mixtures are conceivable which are used in the medical field, in particular in the field of dentistry. The components of these mixtures are usually contained in corresponding storage containers.

The components can be provided in particular in known multicomponent cartridges, which may consist of a plastic material, aluminum or a composite material, for example. Most of the cartridges for each component a hollow cylindrical body or an outer cartridge and a coaxially disposed therein inner cartridge, wherein on one side in each case a movable piston for squeezing the component contained in the cartridge is provided and on the opposite side in each case an outlet opening for dispensing the component. The piston is displaced by applying a force within the cartridge so that the component can be dispensed. When using a cartridge, the dynamic mixer according to the invention can for example be mounted directly on the same, wherein the outlet openings communicate with the inlet openings. Suitable multi-component cartridges are particularly in the EP0992438A1 , of the US5566860A1 or the WO200119700A1 disclosed.

Of course, the components may also be contained in other similar containers known to those skilled in the art. In particular, the use of known film and / or tubular bags may prove useful. For example as disclosed in the WO200061457A1 ,

In particular, known dispensing or dispensing guns, in particular for multicomponent containers, are suitable as dispensing devices used. Such dispensing guns can be operated mechanically, pneumatically or electrically. For example, the EP1409151A1 , the DE29819661A1 or the EP0721805A1 suitable dispensing pistols.

In an advantageous development of the invention, as rotary means, as already mentioned above, a rotary body is used, which is provided separated from the rotor element as a separate component. Preferably, the rotary body is provided within the housing of the dynamic mixer. In addition, an operative connection between the rotary body and the rotor element is provided in order to enable, in particular by means of a rotation of the rotating means by means of the driving medium, a rotation of the rotor element. Through the use of a rotary body, the speed or speed of the rotor element and also the force or the torque of the rotor element can be made adjustable and adaptable to the components or the mixture to be dispensed, in particular by Providence and suitable design of a transmission. Thus, it may prove useful in the use of highly viscous components, for example, to use a gear that leads to a rotation of the rotating body to a rotation of the rotor element at a reduced speed but increased torque.

In the use of a rotary body, it has also been found to be advantageous to use such, which is rotatably mounted about an axis of rotation which is parallel to a rotational axis of the rotor element. With such a design, for example, a particularly good operative connection between the rotary body and the rotor element can be implemented. In particular, by using an internally toothed rotary body in conjunction with a rotor element with an external toothing, an above-mentioned rotation axis arrangement of both components makes sense. In addition, the use of other gears, in particular one or more externally toothed spur gears prove to be useful to provide an operative connection between the rotating body and the rotor element. Preferably, the axes of rotation of all gears or spur gears are at least parallel to the axis of rotation of the rotor element.

Alternatively, it has been found to be advantageous to use a rotating means rotatable about a rotation axis or a rotation body rotatable about a rotation body, wherein the respective axis of rotation corresponds to the axis of rotation of the rotor element. In particular, in a design of the rotor element described above as a rotating means such a design is advantageous. When using a rotary body, such a rotary axis arrangement may also be advantageous. For example, imbalances occurring as a result of the rotation of the movable components can be minimized.

In an advantageous development, the rotating means, which is preferably designed as a rotary body, at least one blade. Preferably the rotating means is arranged with the at least one blade within the housing. The blade is further arranged such that the driving medium may contact the blade in the above-described flow to move the rotating means or the rotating body in the flow. Preferably, the rotating means is at least partially round or annular designed around its axis of rotation, wherein the at least one blade extends at least partially on or on the cladding region or the outer surface or in the region of the outer edge with respect to the axis of rotation in the axial direction.

In an advantageous development, the rotating means, which is preferably designed as a rotary body, at least two blades, in particular on two diametrically opposite sides. Thus, imbalances in the rotating means can be minimized. Preferably, the rotating means is at least partially round or annular designed around its axis of rotation and has a plurality of blades, which are arranged at regular intervals on or on the cladding region or the outer surface or in the region of the outer edge with respect to the axis of rotation. Thus, it is particularly advantageous to provide an at least partially annularly designed rotating means, preferably designed as a rotary body, which has a plurality of blades circumferentially over preferably the entire outer shell surface, which preferably at least partially extend in the axial direction with respect to the axis of rotation. The rotating means, preferably designed as a rotating body is thus designed Schaufelradförmig or impeller, so that the operating principle is similar to that of a turbine.

Thus, it has also been found to be particularly advantageous if at least one blade is profiled slightly curved, preferably similar to a cross-section of an aircraft wing.

In an advantageous development, the rotating means as described above is configured as a rotary body, wherein a transmission is provided for transmitting power from the rotary body to the rotor element.

Another advantage is the use of a dispensing opening for dispensing the propellant. It may be conceivable on the one hand, the driving medium after flowing through the housing, wherein the driving medium is in contact with the rotating means and the same drives and twisted about its axis of rotation, simply leave the discharge opening and let escape. In this case, such an arrangement of the dispensing opening has proved to be particularly advantageous, in which neither the dispensing of the mixture through the dispensing opening is impaired, nor a user who guides the dispensing device. On the other hand, however, the discharge opening can also be arranged such that, for example, a targeted influencing of the mixture delivery is made possible. Thus, the discharge opening may be arranged for example in the front region of the dynamic mixer in the immediate vicinity of the dispensing opening for the mixture. In particular, such a design may prove to be expedient in which the dispensing opening lies within the dispensing opening or is surrounded by the latter, so that the mixture to be dispensed can be flowed on all sides by the drive medium to be dispensed. By such a design, a spray application of the mixture can be made possible by using the propellant, as for example from the DE9011965U1 or the DE4137801A1 is known.

In an advantageous development, a gaseous propellant is used. In particular, compressed air has been found to be particularly useful here. For example, compressed air is available anyway in most workshops and industrial plants and is generally harmless, in particular with regard to the delivery described above by a discharge opening.

1 shows a sectional side view of a dynamic mixing device according to the invention, as a dynamic mixer 1 is configured and for a plurality of fluid components comprising a two-part housing 2 with an upper housing part 3 and a lower housing part 4 , The upper housing part 3 and the lower housing part 4 are in a connection area 14 connected by a snap connection. Also conceivable here are other connection techniques known to the person skilled in the art, such as, for example a snap, a welded, an adhesive, a screw or a clamp connection or a combined connection technique. To fill the components, the lower housing part 4 a first inlet opening 5 for a first component. In addition, a second inlet opening 7 intended for a second component. The inlet openings 5 . 7 may have different diameters and / or cross-sections, which is dependent on the desired mixing ratio of the components. The inlet openings 5 . 7 lead into corresponding inlet channels 6 . 8th that in the lower housing part 4 are arranged. The inlet channels 6 . 8th open into within the lower housing part 4 located as well as with the first-mentioned inlet channels 6 . 8th corresponding and thereby in the upper housing part 3 provided channels 9 , Here are also suitable sealants between the housing parts 3 . 4 provided a seal of the transition between the inlet channels 6 . 8th and the channels 9 can allow leakage of the components between the housing parts 3 . 4 to prevent. The channels 9 turn into an atrium 10 within the upper housing part 3 where the two components can first come into contact with each other, and then get into a mixing room 11 where a mixing of the components takes place. The components mixed into a mixture reach the mixing chamber 11 subsequent outlet opening 15 of the upper housing part 3 through which the mixture is the dynamic mixer 1 leaves.

For mixing the components has the dynamic mixer 1 Further, a rotor element 12 on which in the housing 2 and especially in the mixing room 11 rotatable about an axis of rotation 13 is arranged. The rotor element 12 has a shaft section 18 on, and is with the same in a corresponding recording 17 of the lower housing part 4 used. The rotor element 12 points to the shaft section 18 also a gearing 19 on. The shaft section 18 However, in an alternative embodiment may also be formed as a polygon, which engages in a gear having a corresponding opening, wherein the gear additionally has an external toothing 19 having.

To the shaft section 18 closes a storage section 32 on, with which the rotor element at a storage area 16 of the upper housing part 3 is mounted. The rotor element 12 further extends through said antechamber 10 and the mixing room 11 in the direction of the discharge opening 15 , For mixing the components, the rotor element 12 a first mixing section 28 with a plurality of first wing elements 29 and a second mixing section 30 with a plurality of second wing elements 31 on. At least part of the wing elements 29 . 31 can be used as guiding elements for conveying the components through the mixing chamber 11 in the direction of the outlet opening 15 be educated.

The mixing of the components takes place in the illustrated dynamic mixer 1 therefore at least in three stages. First, a contacting of the components takes place in the antechamber 10 , For this purpose, the rotor element 12 at least one turning surface in this area 33 as a rotationally symmetric trained section. The turning surface 33 has a variable diameter and / or cross section, in particular a decreasing and / or increasing diameter or cross section is conceivable. In the embodiment shown, which is the rotor element 12 in the area of the turning surface 33 cone-shaped and tapers towards the discharge opening 15 , During the rotation of the rotor element 12 be on the in the mixing room 10 introduced components shear forces exerted. As a result, the components are finely mixed with each other. The components then enter the mixing chamber 11 and are from the first mixing section 28 of the rotor element 12 premixed. In the second mixing section 30 Finally, it comes to the complete mixing of the components. The resulting mixture can then through the discharge opening 15 be issued.

The rotation of the rotor element 12 around the axis of rotation 13 takes place with the aid of a propellant, preferably a gaseous propellant, in the present case with the aid of compressed air. The compressed air drives one inside the lower housing part 4 around the axis of rotation 13 rotatably mounted, in the embodiment shown annular or hollow cylindrical shaped rotary body 22 at. For this purpose, the lower housing part 4 a likewise annular, corresponding rotary body receptacle 23 on that, in the direction of the upper housing part 3 is open, so the rotary body 22 before mounting the housing 2 simply in the rotary body holder 23 can be used. The rotary body 22 is designed as an internal gear and therefore has on its inside a toothing 24 on, with which a power transmission via a not shown gear on the rotor element 12 is possible to selbiges for mixing of the components around the axis of rotation 13 to turn.

For rotation of the rotating body 22 has the lower housing part 4 further an addition port 20 on, which can be equipped with suitable connection means, such as a plug-in coupling for a compressed air supply line, not shown, and / or with suitable control devices for controlling the compressed air supply. About the addition opening 20 can put the compressed air in one to the addition port 20 subsequent inflow channel 34 and finally into a flow room 26 reach, which has a connection area for the compressed air between the flow channel 34 and rotating body holder 23 provides. The addition opening 20 has a circular cross-section, wherein the inflow channel 34 at least at its the addition port 20 facing side has the same cross section, so that the inflow duct 34 at least partially cylindrical design. The cylinder axis is orthogonal to the axis of rotation 13 of the rotor element 12 , In the flow room 26 the compressed air comes with the rotating body 22 in contact, the same with radially projecting and in the direction of the flow space 26 pointing and accessible from there for the compressed air blades 25 is equipped, which also in the axial direction with respect to the axis of rotation 13 extend. Said shovels 25 has the rotating body 22 However, at least on two diametrically opposite sides, preferably and so also in the illustrated embodiment, is a plurality of blades 25 circumferentially over the entire shell outer surface of the rotating body 22 intended. The shovels 25 are preferably profiled slightly curved, similar to an aircraft wing. The rotary body 22 is thus designed Schaufelradförmig or impeller. The active principle is similar to that of a turbine. It is therefore a turbomachine, which converts the internal energy of the flowing compressed air into rotational energy and thus into mechanical drive energy. The flow area 26 is designed in an advantageous development arcuate such that the over the addition port 20 and the inflow channel 34 supplied compressed air not perpendicular in the direction of the axis of rotation 13 on the rotary body 22 but at least partially deflected laterally and directly on the blades 25 the same happens to the revolving body 22 in the direction of rotation 46 move. On the occasion of the addition opening 20 opposite side has the lower housing part 4 also a discharge space 27 for the compressed air, to which an outflow channel 35 connects, which in turn to the output of compressed air in a discharge opening 21 empties. The discharge opening 21 has a circular cross-section, wherein the outflow channel 35 at least at its discharge opening 21 facing side has the same cross section, so that the outflow channel 35 at least partially cylindrical design. The cylinder axis is orthogonal to the axis of rotation 13 of the rotor element 12 and corresponds to the above-described cylinder axis of the flow channel 34 , The over the addition opening 20 introduced compressed air thus rotates the rotating body 22 over its blades 25 on the way towards the discharge opening 21 , What if said gear in a rotation of the rotor element 12 results. The outflow space 27 is also in such an arcuate designed in an advantageous development that the by the blades 25 conveyed compressed air directly into the outflow space 27 passes through its arcuate shape, the compressed air in the outflow channel 35 leads over.

Thus, the flows out of the work space 44 over the nozzle-like outflow channel 35 escaping compressed air when working with the dynamic mixer 1 circumferentially at the delivery opening 15 over there and comes into contact with the mixture to be dispensed. In this way, in particular with appropriate design of the viscosity of the mixture and the pressure of the compressed air, spraying or spraying of the mixture by means of the compressed air via the discharge opening projecting in the distal direction 21 be enabled. Of course, a different type of discharge opening 21 conceivable, in particular the output of the mixture from the discharge opening 15 not impaired.

For mixing the components within the mixing chamber 10 is again the rotor element 12 provided, which is rotatable about drive components, ie a transmission. The rotor element 12 is here again at a proximal shaft section 18 in a receptacle of the lower housing part 4 around the axis of rotation 13 rotatably mounted. The drive components set themselves as in the embodiment shown above with the shaft portion 18 engaged outer gears 37 . 41 on. The external gears 37 . 41 in turn, are engaged with the rotating body 22 , Both external gears 37 . 41 , as well as rotary body 22 are also here by means of appropriate recordings in the lower housing part 4 rotatably mounted. In the embodiment shown, the rotary body extends in the distal direction within the working space 44 and partially along the outside of the mixing chamber 11 surrounded area of the middle housing part 49 , The middle housing part 49 is designed substantially hollow cylindrical in this area, so that the rotary body 22 here around the outer surface of the middle housing part 49 is rotatable. In this section, the rotating body 22 shovel 25 on, the attack surfaces for through the work space 44 from the addition opening 20 in the direction of the discharge opening 21 represent flowing compressed air to a rotation of the rotating body 22 around the axis of rotation 13 in the direction of rotation 47 to enable. Said shovels 25 has the rotating body 22 However, at least on two diametrically opposite sides, preferably and so also in the illustrated embodiment, is a plurality of blades 25 circumferentially over the entire shell outer surface of the rotating body 22 intended. The upper housing part 3 is also in the range of the blades 25 Designed nozzle-shaped, so that the compressed air is accelerated in this area. The shovels 25 are again designed such that they the nozzle-like shape of the upper housing part 3 follow stepwise in the embodiment shown. Further, the blades are 25 thereby slightly curved profiled, similar to an aircraft wing. The rotary body 22 is thus designed Schaufelradförmig or impeller. The active principle is similar to that of a turbine. It is therefore a turbomachine, which converts the internal energy of the flowing compressed air into rotational energy and thus into mechanical drive energy. Upon rotation of the rotary body 22 he turns with the blades 25 equipped section around the the mixing room 10 enclosing area of the middle housing part 49 , The rotation of the rotating body in the direction of rotation 47 results in a rotation of the external gears 37 . 41 in the direction of rotation 48 , which in turn causes a rotation of the rotor body 12 in the direction of rotation 46 around the axis of rotation 13 entails.

5 shows a further variant of a dynamic mixing device, which is designed as an assembly that on the one hand as a first unit the dynamic mixer 1 on the other hand comprises a spatially separated second unit, the drive unit, which in the present case to a double container 50 is provided, but so acting with the dynamic mixer 1 is connected, that a rotation of the rotor element 12 around the axis of rotation 13 can be enabled via the drive unit. The operation of the dynamic mixer is off with the mixer 1 comparable. With regard to the supply of the components and the rotor element 12 in the mixing room 10 is similar to the dynamic mixer shown here 1 the mixer from the 1 to 3 so that the relevant descriptive passages in that regard 5 supplement description. As a major difference is in the dynamic mixer 1 in 5 as already described, the drive of the rotor element 12 spatially from in particular the lower housing part 4 and the upper housing part 3 separated. The drive is rather as part of the double container 50 designed. The double container 50 is in the illustrated embodiment with the dynamic mixer 1 connected and includes a first container 51 and a second container 52 , The first container 51 serves to receive a first component, via the first inlet opening 5 in the dynamic mixer 1 can be fed. The second container 52 in turn, the recording of the second component, the corresponding over the second inlet opening 7 in the dynamic mixer 1 fed. is.

The containers 51 . 52 are designed as a hollow cylinder and may have pistons, not shown, by means not shown piston rods or other propulsion devices within the container 51 . 52 are displaceable for the output of the components. Both containers 51 . 52 are arranged parallel to each other and spaced so that in the space between the containers 51 . 52 a wave 53 arranged and rotatable about the axis of rotation 13 is stored. The wave 53 is during assembly of the double container 50 in a wave recording 54 at the shaft section 18 been inserted. Here is the wave 53 in this area and the wave recording 54 designed such that a rotation of the shaft 53 in one direction of rotation 56 around the axis of rotation 13 to a rotation of the rotor element in the direction of rotation 46 leads, the latter being the direction of rotation 56 the wave 53 equivalent.

For driving the shaft 53 is in terms of the dynamic mixer 1 opposite side of the double container 50 a rotary body 22 provided, which about the axis of rotation 13 is rotatable and as described above designed as an internal gear, wherein the rotary body 22 with its teeth 24 with a corresponding external toothing 55 the wave 53 engaged in this area. Furthermore, the rotary body 22 with shovels 25 equipped, like in the 1 shown embodiment are arranged and arranged. To the rotating body 22 in a rotational movement about the axis of rotation 13 to put here is the addition opening 20 provided for acting on compressed air as the driving medium. Corresponding is also a discharge opening 21 provided, can escape through the compressed air.

Also, in a further variant, a design is conceivable in which the drive or the drive unit is not part of the double container 50 is, but present as a separate component or in turn mounted on another component. In this case, the drive unit has connecting means for connecting a with respect to the operation of the mixer 1 comparable dynamic mixer, said in the assembled state of the drive unit and dynamic mixer said dynamic mixing device is provided. With regard to the supply of compressed air and the mode of operation, reference should again be made here to the preceding exemplary embodiments, which in this respect supplement the description of this variant with the relevant description passages. The said drive unit further has a coupling possibility for the rotor element of the dynamic mixer in order to rotate the rotor element by means of the blowing medium supplied via the feed opening for mixing the components. Here is in particular on the with 5 shown embodiment and the relevant description passages that supplement the description of this variant. By providing such a drive unit, for example, dynamic mixers already available on the market can be used in accordance with the invention.
