Definitions
- the invention relates to a device for mixing liquids according to the preamble of claim 1.
- liquids in question are generally filled in relatively large quantities into a reaction vat of the appropriate size and stirred in this using a stirrer until there is complete mixing or the desired reaction has taken place. This procedure is simple from the point of view of the process control and in terms of the expenditure on equipment, but it also has considerable disadvantages.
- a third disadvantage is that when changing the product, the mixing tank and the mixing tools have to be cleaned, which is usually only possible manually. On the one hand, this is heavy physical work, which should be avoided as far as possible for reasons of occupational safety, furthermore, such manual cleaning is usually very time-consuming, which leads to correspondingly long changeover times.
- the device according to the invention has a central tube in which at least two feed devices end.
- a mixing head is connected upstream of the central tube, in which at least two liquids are premixed, and / or a mixer is arranged downstream of the central tube, in which the liquids supplied to the central tube are mixed.
- a mixer is arranged downstream of the central tube, in which the liquids supplied to the central tube are mixed.
- gas pressure nozzles can end in the central tube. Such nozzles can be used to generate a turbulent flow in the central tube, as a result of which the liquids flowing in the central tube are mixed or improved without mechanical aids being required within the central tube.
- the central tube can thus be kept free of mixing devices, which considerably simplifies cleaning of this central tube in the event of production interruptions or product changes.
- this makes it possible to arrange an axially displaceable piston in the central tube, by means of which the central tube can be cleaned automatically.
- FIG. 1 shows an embodiment with an upstream mixing head
- 2 shows a configuration similar to FIG. 1 with an obliquely opening supply line
- Figure 3 shows a preferably used mixing head
- FIG. 4 shows an embodiment with gas pressure nozzles
- FIG. 5 shows an alternative embodiment to FIG. 4,
- Figure 6 shows an embodiment with a downstream static mixer
- Figure 7 is a 3-dimensional representation of an embodiment with two
- FIG. 8 the embodiment shown in FIG. 4 with a cleaning spray head
- FIG. 9 shows a 3-stage network
- Figure 10 two central tubes that end in a dynamic mixer.
- liquids are understood to mean all flowable substances and substance mixtures, in particular also suspensions, colloidal solutions and the like.
- Figure 1 shows a first embodiment of the present invention.
- the axially displaceable piston 12 is arranged in the cylindrical central tube 10 and can be pushed through substantially the entire length of the piston for cleaning purposes.
- the first feed device 20 and the second feed device 30 end in the wall of the central tube 10.
- the first feed device 20 has a mixing head 23, which can be designed, for example, according to FIG. 3; this will be discussed in more detail later.
- the first feed line 21 and the second feed line 22 end in the mixing head 23, so that two components A, B are mixed in the mixing head 23 and this mixture is drawn off into the central tube 10. will give. In some applications it is conceivable that the two components A, B react to form a new chemical (AB) '.
- a liquid C is fed into the central tube 10 through this third feed line 31 and then mixes with the liquid mixture AB.
- two substances would initially be premixed intensively in the mixing head 23, which can be achieved in particular if the mixing head 23 is switched off according to FIG. 3, and after this premixing, the remaining amount of one of the two components is then added.
- Such a procedure is known, for example, from everyday life when mixing cocoa.
- cocoa is first mixed with a small amount of milk without lumps and only in a second step is the remaining amount of milk added.
- FIG. 2 shows an embodiment which is similar to that of FIG. 1, but here the third feed line 31 ends at an acute angle in the wall of the central tube 10 in such a way that the liquid C fed through this third feed line 31 is introduced counter to the actual flow direction. so that a relatively strong formation of turbulence takes place, which of course improves the mixing.
- This effect can also be intensified by injecting the corresponding liquid at high pressure (some 10 to 100 bar) through the third feed line 31.
- FIG. 3 shows a cross section through a mixing head 23 which is preferably used.
- a mixing head is known from DE 199 60 202.6 A1, the Disclosure content is expressly made the subject of the present application here.
- Such a mixing head makes it possible to mix almost any liquids, in particular also highly viscous liquids, and it has a self-cleaning function.
- the two liquids to be mixed are injected into the cylinder via the two nozzles 61, 62 under high pressure - for this purpose the corresponding supply lines have high-pressure pumps.
- the cylinder Z is closed on an upper side by the control piston K, which can be rotated about its longitudinal axis by means of an electric motor.
- the control piston K is pierced by the stirring rod R, so that the liquids to be mixed in the cylinder Z can be subjected to a strong stirring process.
- the control piston K can be moved along its longitudinal axis.
- the stirring rod R is also stripped off.
- Figure 4 shows an embodiment which is similar to that in Figure 1.
- this exemplary embodiment has gas lines 50 which end in the wall of the central tube 10.
- An inert gas for example nitrogen, can be blown into the central tube 10 through these gas lines 50, where it causes turbulence. It can thus be achieved that the liquids flowing in the central tube 10 are better mixed.
- the entry angle is preferably selected such that the inert gas flows counter to the main liquid flow.
- FIG. 5 shows a variation to FIG. 4, but here premixing of two components was dispensed with.
- two liquids A, B are simply fed to the central tube 10 via corresponding feed lines and mixed in the central tube 10 with the aid of inert gas from the gas line 50.
- Such a procedure could then be recommended, for example be when a relatively thin liquid A1 is to be mixed with a color B1.
- FIG. 6 shows an embodiment that deviates from the principle described so far.
- final mixing takes place only in a mixer connected downstream of the central tube 10, here a static mixer 40.
- the corresponding liquids are fed to the central pipe 10 via first and second feed devices 20, 30, in which a certain mixing will usually already take place.
- a mixer as mentioned in this case a static mixer 40, is connected downstream of the central tube.
- This static mixer 40 is preferably screwed to the central tube 10 via flanges F, so that it can be removed from the actual central tube 10 for the purpose of cleaning.
- FIG. 7 shows an exemplary embodiment which combines the principle shown in FIG. 1 with the principle shown in FIG.
- both feed devices 20, 30 have mixing heads, in each of which two feed lines connected via pumps P also end here.
- four liquids can be mixed together.
- a static mixer 40 is connected downstream of the central tube 10.
- cleaning spray head 14 which can be moved into the central tube 10 and by means of which the central tube 10 can be cleaned with cleaning liquids (for example hot water) injected under high pressure. It is also conceivable to combine the principle of the axially displaceable piston with such a cleaning spray head device.
- the invention shown here not only has the advantage that it can be cleaned very easily and fully automatically, and thus batch changes can be carried out easily, it also offers the possibility of very precise and selective process control.
- the embodiment shown in FIG. 7 will be discussed again.
- This device can be used, for example, to produce a mixed or reaction product from 4 liquids. Because two liquids are premixed before being fed into the central tube 10, a mixing or reaction sequence can be defined, which drastically increases the process control and intervention options compared to a classic vat mixing technology.
- FIG. 9 shows that this basic principle can be continued as desired.
- a plurality of central tubes 10 which in turn end in a common mixer, here a dynamic mixer 42.
- any number of feed devices can end in these central tubes, which can be designed entirely or partially as mixing heads. In this way, a complete network can be set up in which any complicated mixing and / or reaction processes can be carried out.
- the respective central tubes 10 preferably end directly in a central mixer, in which an automatic cleaning device is again provided, so that even with such complex structures, ren a very simple and in preferred embodiments fully automatic cleaning is maintained.
- a three-stage mixing process is shown in FIG. 9, but it goes without saying that this branching principle can also be extended to four and more stages.
- static mixer is understood to mean a mixer in which guide elements, which mix the medium flowing through, in particular cause turbulence, are arranged rigidly in a mixer housing.
- static mixer can be designed, for example, in the form of a spiral mixer.
- “Dynamic mixer” is understood to mean a mixer in which driven, in particular rotating, stirring elements mix the medium flowing through.
