Definitions

  • the invention is based on a device for mixing at least two flowable components according to the preamble of the first claim.
  • Mixing devices are generally used where two or more streams of flowable materials or components have to be mixed to form a completely or partially mixed common flowable material stream. Mixing devices are used, which are disposed of after use or cleaned and reused several times.
  • Static mixers having no moving parts are particularly suitable for mixing low viscosity materials.
  • dynamic mixers are preferably used with a rotor which is rotatably arranged in a mixing chamber into which the substances to be mixed are introduced.
  • Mixing devices of this type are described for example in EP 0301201 A1, EP 1106243 A2, DE 10112904A1 and EP 1106243 A2.
  • the devices described in these documents have a rotor housing which is provided with two of the introduction of the components to be mixed material openings and a drive opening through which a drive shaft is positively inserted into a recess of the rotor.
  • the known mixing device may need to be adjusted accordingly with additional effort.
  • a delay chamber is provided for one of the components for this purpose. To realize this delay chamber corresponding molds are necessary.
  • the invention has for its object to provide an improved dynamic mixer of the type mentioned.
  • the dynamic mixer is designed to be simple, inexpensive to produce and easy to use. Parts of the mixing device, which are to be disposed of after use of the mixing device, should be particularly simple and inexpensive and can be produced only with little material. Furthermore, the mixing chamber and any transfer chambers of the dynamic mixer with small volumes should be feasible, so that the complete Replacement or maintenance of the dynamic mixer only a small amount of mixed material must be disposed of or removed.
  • the dynamic mixer has a rotor coupled to a drive shaft, which is arranged rotatably in a mixing chamber provided in a rotor housing, to which at least a first and a second component K1, K2 can be fed.
  • the drive shaft has at least one channel through which the second component K2 can be introduced into the mixing chamber.
  • the complexity of the mixing device is considerably reduced.
  • no separate connection to the rotor housing is provided, which is why this can be made extremely simple and inexpensive.
  • the rotor which has a body provided with rotor blades whose longitudinal axis is preferably aligned coaxially to the axis of the drive shaft, preferably has a coupling cylinder, in which the drive shaft is inserted, which has at least one closure element, by means of which the drive shaft rotatably coupled to the rotor is.
  • the connection of the rotor and the drive shaft with a screw or bayonet connection, so that the rotor is held firmly and can not abut on the rotor housing, whereby the generation of frictional heat is avoided, the running between the two components K1, K2 reaction processes can accelerate.
  • the rotor and the drive shaft are connectable to each other such that the second component K2 can pass through only one or more transfer channels in the rotor to zones in the mixing chamber, which are traversed by the first component K1.
  • the second component K2 can advantageously be divided into different streams which impinge on the first component K1 in different zones of the mixing chamber. A uniform mixing can therefore be achieved with fewer rotor rotations and thus low mechanical energy and therefore reduced process heat, which is particularly advantageous for highly viscous substances. Premature curing of parts of the mixed product within the mixing chamber can therefore be avoided, so that the service life of the parts to be replaced after use significantly extended.
  • the transport of the first component K1 into the mixing chamber and the transport away of the mixed product K1xK2 from the mixing chamber can be accelerated.
  • a preferably helically extending conveyor element and / or an output screw is provided at the output end of the rotor body.
  • the rotor housing provided with an outlet opening has only one inlet opening into which the drive shaft, which may already be connected to the rotor, and also the first component can be inserted.
  • this inlet opening and thus the entire rotor housing can be made extremely simple and manufactured with minimal effort.
  • the rotor housing can be formed in a simple manner by a front end provided with an end piece cylindrical piece which is tightly connectable to an opening of a first device body, through which the drive shaft and thus the second component is guided and in which a first transfer chamber is formed, which is connected to the outlet opening of a first supply device, preferably a first valve, through which the first component K1 is insertable into the first transfer chamber and further along the drive shaft into the mixing chamber.
  • the cylindrical piece provided on the rotor housing has, for example, an external thread or an external flange which can be connected to an internal thread of the first transfer chamber or to a flange connected to the first transfer chamber by means of a union nut and provided with an external thread.
  • the rotor and the rotor housing can therefore be quickly assembled and disassembled with a few simple steps.
  • the second component K2 is connected directly or via an input channel to a second transfer chamber provided in the first or in a second device body, into which the drive shaft protrudes or through which the drive shaft passes, and which connects to the outlet opening second supply device, preferably a second valve, is connected, through which the second component K2 is inserted into the shaft channel.
  • a second transfer chamber provided in the first or in a second device body, into which the drive shaft protrudes or through which the drive shaft passes, and which connects to the outlet opening second supply device, preferably a second valve, is connected, through which the second component K2 is inserted into the shaft channel.
  • the outlet opening of the first and / or second valve which is mechanically, hydraulically or pneumatically actuated, is preferably by means of a Needle openable or lockable, which mounted axially displaceable within the valve body by means of an elastic bearing element, which closes the valve chamber adjoining the outlet opening and to an inlet opening tight.

  • the needle has, for example, at least one annular flange on which is held by the bearing element or embedded therein.
  • the solution according to the invention also makes it possible to set the quantities of the conveyed components K1, K2 and the flow rates with simple measures.
  • the drive shaft in the flow region of the two components K1, K2 is provided with corresponding metering elements, for example metering rings, which inhibit the material flow.
  • the volume in the first transfer chamber can be reduced by a metering ring so that the delay time after which the first component K1 enters the mixing chamber can be set.
  • DE 10112904 A1 describes that the use of a delay chamber may be desirable.
  • the transfer chamber can therefore be extended to a delay chamber with variable volume and variable delay time.
  • the inventive dynamic mixer is therefore ideal for mixing components with different volume fractions.
  • the device can be optimized in a simple manner with respect to the desired volume ratios.
  • the components can be introduced into the transfer chambers via supply lines or from locally mounted cartridges.
  • the dynamic mixer according to the invention can be advantageously realized, in particular with low inertia of the components used, even without attached valves.

  • the drive shaft 3 is guided through two adjoining device bodies 41, 51, through which the components K1, K2 to be mixed are introduced into the mixing chamber 15.
  • the device bodies 41, 51 are provided with valves 4, 5, which have a valve chamber 42; 52 with an inlet opening 421; 521 and an outlet opening 422, 522, by means of a pneumatically or hydraulically actuated valve needle 43; 53 can be completed or opened.
  • a first and a second transfer chamber 49; 59 in which the through the outlet openings 422; 522 passed through components K1, K2 enter.
  • the first component K1 is supplied to the mixing chamber 3 through the first transfer chamber 49 along the outside of the drive shaft 3.
  • the second component K2 is introduced from the second transfer chamber 59 through an input channel 32 provided in the drive shaft 3 into the shaft channel 31 and further conveyed to the mixing chamber 15.
  • the first transfer chamber 49 is separated by means of a first seal 351 on one side of bearing elements 36, by means of which the drive shaft. 3 is rotatably supported within the device body 41, 51. On the other hand, the first transfer chamber 49 is opened against the mixing chamber 15.
  • the second transfer chamber 59 is closed on both sides by means of second and third seals 352, 353, so that the supplied second component K2 can only escape via the input channel 32 and the shaft channel 31 of the drive shaft 3.
  • connection of the rotor 2 and the shaft 3, in this preferred embodiment, is shown enlarged in Figure 2.
  • the rotor 2 has on the input side an integrally formed on the rotor body 21 coupling cylinder 22, within which the provided with the outlet opening of the shaft 31 end piece of the drive shaft 3 is anchored.
  • a preferably metal coupling sleeve 7 is integrated into the coupling cylinder 22, which has at least one coupling channel 71 into which a coupling element 33 connected to the drive shaft 3 can be introduced and locked, so that a bayonet closure results.

  • sealing elements such as O-rings are advantageously placed on the drive shaft 3.
  • one or more transfer channels 212 can be guided, by which the second component K2 is divided into a plurality of streams, which are guided to arbitrary locations in the mixing chamber 15.
  • the mixing of the components K1, K2 takes place in this preferred embodiment, therefore, not by the rotor 2 alone, but is favored by the targeted division and feeding the second component K2.
  • the required mixing of the components K1, K2 can therefore already be achieved with a few rotations of the rotor 2, for which reason less heat is supplied to the mixed product K1xK2, which would accelerate undesired reaction processes therein.
