Definitions
- the invention relates to a method for mechanically spraying surfaces or blowing in insulation and / or insulating material, in particular mineral fibers, into cavities by evenly conveying and accelerating the insulating / insulating material up to the outlet opening of the blowing hose, possibly with the addition of finely divided binder and Discharge using a spray gun.
- the invention also relates to a device for spraying or blowing in mineral fibers for insulation or insulation, with a blow-in hose connected to a pump or blower, a feed for the binder and a spray nozzle on the outlet side of the blow-in hose for carrying out the method.
- Mineral fibers are used for insulation against heat and cold, for insulation against noise pollution, for the production of fire protection and for many other purposes. These are assigned in the form of mats or molded parts to the parts to be insulated or insulated. Poorly accessible areas, in particular cavities and narrow bodies, cannot be insulated in this way or an insulation material cannot be accommodated there. Therefore, it has gone over to blowing in the insulation or insulating material simply and quickly and fixing it by adding, for example, binding agents, so that it is vibrated or the like. Load can not be compressed. This ensures uniform insulation after the material has hardened. The blown insulation material is namely glued by the binder so that a molded shell is created which fills all cavities evenly and remains long-term.
- the binder is added to the insulating / insulating material in the area of the spray gun or nozzle in such a way that it enters the blow-out stream at an angle, mixes in the process and leads to the desired wetting.
- a disadvantage is that even when binder is added, uniform wetting is not always the case can be reached so that dust is generated. In particular, however, dust arises when such mineral fibers or the like. Blowing materials without the addition of binders. Spraying water is not enough.
- the invention is therefore based on the object of a dust-free spraying and blowing process for insulating and insulating materials made of mineral fibers or the like. To create material and a device suitable for implementation.
- the object is achieved in that a special foam is added to the insulating / insulating material shortly before leaving the blow-in hose and the mixture is then discharged together.
- the foam is produced in the machine by intensive mixing of water, air and a special foamer and then mixed with the insulation / insulating material.
- a finished foam with the insulating or insulating material i.e. is mixed with the mineral fibers so that the advantageous integration into the foam cushion described above is possible.
- the fiber is practically put into the finished foam, enveloped by it, carried on and held for as long as is optimal for transport and processing. Thereafter, the foam dissolves almost automatically, without the included special foam for the curing process or the insulation process causing disadvantages.
- Another embodiment provides that water and a foamer are mixed with the addition of air and at the same time mixed with the insulating and insulating material.
- water and a foamer are mixed with the addition of air and at the same time mixed with the insulating and insulating material.
- excessive moistening can occur, however, because there is a risk that the fibers will influence the foaming process.
- this process can also have advantages, as mentioned, because it provides foaming and mixing in one operation.
- binders is advantageous, especially if material is used as insulation / insulating material is used, which should have a particularly good dimensional stability, for example because it is in safety cabinets, chimneys, steel fireplaces, for device linings or the like. is used. Then it is advantageous if the foam is generated from the binder, special foamer and air and then or at the same time mixed and discharged with the insulating / insulating material.
- the binder takes on the function of water here, and depending on the type of binder, the special foamer can even be dispensed with, since the binder and air together produce the foam cushion in which the insulation / insulation material can then be embedded.
- the proportion of special foamers should be kept low. It is provided according to the invention that it is admixed with a proportion of 0.5 to 6%, which essentially depends on the requirements for the foam with regard to its stability and the size of its bubbles.
- the size of the mineral fibers to be incorporated is also a decisive factor, it being expediently provided that the proportion of the special foamer is increased with a reduction in the fiber dimensions, in order in this way to increase the stability of the foam in particular. It is also important whether the material should then be further processed and shaped by hand, since then an appropriate optimization of the foam is advantageous. However, if cavities are simply sprayed out, the proportion of foaming agents can also be reduced, since this essentially involves the dust-free introduction of the mineral fibers or the insulating and insulating material.
- a device is used to carry out the method, in which the insulation / insulating material is brought in via a blower or a pump through an injection hose, in order to then binders and the like. add and discharge the material through the spray nozzle on the outlet side.
- the method expands such a device by designing the inlet hose as a double tube on the outlet side, into which a foam tube opens and the inner tube of which is equipped with adjustable locks. With such a design, the foam produced in the machine is entered in the double pipe through the locks into the interior of the blow-in hose or into the inside of the double pipe, where it receives the insulation / insulating material, embeds it and then discharges it together with it via the nozzle becomes.
- the air required for optimal adjustment of the foam can still be mixed if the outer tube of the double tube, as proposed according to the invention, has a plurality of bores which are arranged around the circumference and are used for air supply. Through these holes, the air enters the intermediate space as required, in order to be mixed with water, foamer or binder and processed into foam. As mentioned above, this foam is then discharged through the locks into the interior, where it is mixed with the insulating / insulating material.
- a kind of check valve is to be arranged in these bores, so that air is sucked in by the internal pressure in the space between the outer and inner tube, but cannot flow the other way round.
- the structure is made easier on the one hand and the spray gun is easier to handle if the foam tube, as provided according to the invention, is connected to a binder or a water reservoir.
- Corresponding valves can be used to supply either binder and / or water for the production of the foam, depending on the intended use for the end product, the production in the machine or the appropriately trained foam pipe. Since both the binding agent and the water are only required in relatively small amounts, a hose of small diameter can be used, so that larger distances to the blowing machine can also be bridged with the spray gun and the downstream hoses, so that the work as a whole is thereby facilitated .
- Optimal mixing of the material before leaving the spray nozzle is ensured by arranging a mixing hose between the double pipe and the spray nozzle.
- this mixing hose the foam, which is produced separately and then mixed with the insulating / insulating material, is mixed again with the material in such a way that the desired foam cushion embedding the smallest fiber particles really emerges at the spray nozzle in order to fill the intended cavity or else the intended one Cover area.
- the invention is characterized in particular by the fact that a method has been created with which, in a surprising manner, even fine-fiber material can be processed safely and dust-free for insulation and insulation purposes. It is not only possible to blow this material into cavities, but also to spray surfaces on which this material then advantageously adheres.
- the special foam produced which consists of air and water or of air and binding agent or also foamer, can be discharged with the mixing or spray gun, taking the fiber particles with them and embedding them safely. This mass is then surprisingly easy to process further, whereby it can advantageously be filled into molds or cavities or can be sprayed onto ceilings, walls and steel parts in order to then be smoothed.
- the carrier foam disappears after a certain time, so that then an optimally firm and advantageous molded part is created, which the intended insulation or Isolation task can advantageously perform.
- a range of binders are available for appropriate applications as thermal insulation with mineral wool, fire protection or high-temperature insulation with ceramic fibers, which meet the respective requirements and can be optimally processed using the method and the device.
- the method and the device are thus very versatile and optimally meet the special environmental protection conditions because the mineral fibers and other insulation / insulating materials to be processed cannot get into the environment during the processing process and because they also work optimally as a molded part after processing. It is to be regarded as particularly advantageous that only a relatively small amount of water has to be added, so that the end material can dry out quickly.
- a significantly reduced spray loss and a low density are also advantageous, since the foam achieves a correspondingly favorable structure. Attention has already been drawn to the dust-free processing and the possibility of smoothing and deforming the applied material.
- Fig. 1 shows a blowing machine (1) in simple design, with the suction hose on the front (2) and the injection hose (3) are to be connected to the injection machine (1) via connections.
- Plug connections (4) can also be seen, by means of which the various binders or water supply hoses can be connected to the accumulators accommodated in the blowing machine (1).
- Plug connections (4) are also provided for the electrical supply to the blowers housed in the housing of the blowing machine (1).
- (5) indicates a spray nozzle or the connection provided for it, (7) the spray gun, details of FIG. 2 being shown.
- the device shown in FIG. 2 serves as the spray gun (7), it being a piece of pipe into which the injection hose (3) opens and the foam pipe (6).
- the spray nozzle (5) is provided at the front at the tip and is used to discharge the material after the mixing process.
- the outer tube (9) of the double tube (8) has a significantly larger diameter than the inner tube (13) equipped with the locks (10, 11).
- Fig. 3 shows that the locks (10, 11) are arranged distributed over the circumference of the inner tube (13) and can be partially or completely closed via slide (12). The quantity can be regulated using adjusting screws.
- the foaming process can optionally be supplemented in the intermediate space (17) between the inner tube (13) and the outer tube (9) in order then to bring a suitably constructed foam through the locks (11, 12) into the interior (18).
- the supply of water / binder and air pressure can also be varied during foam production. This means that the foam can be adjusted at any time according to the conditions of use.
- the mass mixed in the interior (18) is then conveyed into a mixing hose (16), the location and design of which is shown and indicated in FIG. 2.
- a further and final mixing of foam and fibers takes place in this mixing hose (16), so that only optimally embedded fibers can leave the spray gun (7) via the spray nozzle (5).
- this mass can then be processed without any problems.
- the advantage is around 50% lower water consumption, a low spray loss (negligible), a low density of the mass and above all a completely dust-free spraying and other processing of the mass.

Abstract
Description
Die Erfindung betrifft ein Verfahren zum maschinellen Spritzen von Flächen oder Einblasen von Dämm- und/oder Isolierstoff, insbesondere aus Mineralfasern, in Hohlräume durch gleichmäßiges Fördern und Beschleunigen des Dämm-/Isolierstoffes bis zur Austrittsöffnung des Einblasschlauches ggf. unter Zumischung von fein verteiltem Bindemittel und Austragen mit Hilfe einer Spritzpistole. Die Erfindung betrifft außerdem eine Vorrichtung zum Spritzen oder Einblasen von Mineralfasern zum Dämmen oder Isolieren, mit einem mit einer Pumpe oder Gebläse verbundenen Einblasschlauch, einer Zuführung für das Bindemittel und einer Spritzdüse ausgangsseitig des Einblasschlauches zur Durchführung des Verfahrens.The invention relates to a method for mechanically spraying surfaces or blowing in insulation and / or insulating material, in particular mineral fibers, into cavities by evenly conveying and accelerating the insulating / insulating material up to the outlet opening of the blowing hose, possibly with the addition of finely divided binder and Discharge using a spray gun. The invention also relates to a device for spraying or blowing in mineral fibers for insulation or insulation, with a blow-in hose connected to a pump or blower, a feed for the binder and a spray nozzle on the outlet side of the blow-in hose for carrying out the method.
Zur Isolierung gegen Wärme und Kälte zum Dämmen gegen Geräuschbelastung, zur Herstellung eines Brandschutzes und zu vielen anderen Zwecken werden Mineralfasern eingesetzt, wobei diese in Form von Matten oder Formteilen den jeweils zu islierenden oder dämmenden Teilen zugeordnet werden. Schlecht zugängliche Bereiche, insbesondere Hohlräume und enge Körper sind auf diese Weise nicht zu isolieren bzw. dort ist ein Dämmstoff nicht unterzubringen. Daher ist man dazu übergegangen, den Dämmstoff bzw. Isolierstoff einfach und schnell einzublasen und durch Zugabe beispielsweise von Bindemittel zu fixieren, so daß er durch Vibration o.ä. Belastung nicht verdichtet werden kann. Damit ist eine gleichmäßige Isolierung nach dem Aushärten des Materials gewährleistet. Das eingeblasene Dämmstoffmaterial ist nämlich durch das Bindemittel so verklebt, daß eine Formschale entsteht, die alle Hohlräume gleichmäßig füllt und auch langfristig bleibt. Hierzu wird dem Dämm-/Isolierstoff im Bereich der Spritzpistole bzw. Düse das Bindemittel zugemischt und zwar so, daß es von schräg her in den Ausblasstrom hineingelangt, sich hierbei vermischt und zu der gewünschten Benetzung führt. Nachteilig ist, daß auch dann, wenn Bindemittel zugegeben wird, eine gleichmäßige Benetzung nicht immer zu erreichen ist, so daß Staub entsteht. Insbesondere entsteht aber Staub, wenn derartige Mineralfasern o.ä. Materialien ohne Bindemittelzugabe verblasen werden sollen. Einsprühen von Wasser reicht nicht.Mineral fibers are used for insulation against heat and cold, for insulation against noise pollution, for the production of fire protection and for many other purposes. These are assigned in the form of mats or molded parts to the parts to be insulated or insulated. Poorly accessible areas, in particular cavities and narrow bodies, cannot be insulated in this way or an insulation material cannot be accommodated there. Therefore, it has gone over to blowing in the insulation or insulating material simply and quickly and fixing it by adding, for example, binding agents, so that it is vibrated or the like. Load can not be compressed. This ensures uniform insulation after the material has hardened. The blown insulation material is namely glued by the binder so that a molded shell is created which fills all cavities evenly and remains long-term. For this purpose, the binder is added to the insulating / insulating material in the area of the spray gun or nozzle in such a way that it enters the blow-out stream at an angle, mixes in the process and leads to the desired wetting. A disadvantage is that even when binder is added, uniform wetting is not always the case can be reached so that dust is generated. In particular, however, dust arises when such mineral fibers or the like. Blowing materials without the addition of binders. Spraying water is not enough.
Der Erfindung liegt daher die Aufgabe zugrunde, ein staubfreies Spritz- und Einblasverfahren für Dämm- und Isolierstoffe aus Mineralfasern o.ä. Material und eine zur Durchführung geeignete Vorrichtung zu schaffen.The invention is therefore based on the object of a dust-free spraying and blowing process for insulating and insulating materials made of mineral fibers or the like. To create material and a device suitable for implementation.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß dem Dämm-/Isolierstoff kurz vor Verlassen des Einblasschlauches ein Spezialschaum beigemischt und daß das Gemisch dann gemeinsam ausgetragen wird.The object is achieved in that a special foam is added to the insulating / insulating material shortly before leaving the blow-in hose and the mixture is then discharged together.
Mit einem solchen Verfahren ist es dann möglich, einen Spezialschaum zu erzeugen, der so mit den Fasern vermengt wird, daß selbst feinste und kleinste Faserpartikel in einem Schaumkissen schwebend ausgetragen werden. Diese Masse kann dann problemlos weiterverarbeitet werden, indem daraus Formen hergestellt oder Hohlräume ausgefüllt werden, indem Decken, Wände oder Stahlteile angespritzt und anschließend geglättet werden. Besonders vorteilhaft ist, daß diese Masse nach dem Austragen optimal verarbeitet, beispielsweise von Hand verarbeitet und geformt werden kann, wobei mit dem Verschwinden des Trägerschaums während des Trocknungsvorganges ein festes Formteil aus gebundenen Fasern entsteht, welches langfristig elastisch und stabil bleibt. Dabei ist es möglich, bei Wärmeisolierungen beispielsweise mit Hilfe von Mineralwolle, beim Brandschutz oder bei der Hochtemperaturisolierung keramische Fasern mit Bindemitteln einzusetzen, so daß das erfindungsgemäße Verfahren sehr vielseitig angewendet und verwirklicht werden kann. Besonders vorteilhaft ist dabei, daß auch bei feinstem Material, d.h. kleinsten Faserpartikeln und beim Spritzen beispielsweise auf eine Fläche diese kleinsten Partikel nicht freigesetzt werden, sondern vielmehr im Schaum gebunden auf die Fläche aufgebracht werden und damit unschädlich bzw. umweltfreundlich zu verarbeiten sind. Der dafür notwendige Aufwand ist gering, so daß ein derartiges Verfahren als besonders technisch fortschrittlich angesehen werden muß.With such a method it is then possible to produce a special foam which is mixed with the fibers in such a way that even the finest and smallest fiber particles are suspended in a foam cushion. This mass can then be easily processed by making molds or filling cavities, by spraying on ceilings, walls or steel parts and then smoothing them. It is particularly advantageous that this mass can be optimally processed after discharge, for example processed and shaped by hand, with the disappearance of the carrier foam during the drying process resulting in a solid molded part made of bound fibers which remains elastic and stable in the long term. It is possible to use ceramic fibers with binders for thermal insulation, for example with the help of mineral wool, for fire protection or for high-temperature insulation, so that the method according to the invention can be used and implemented in a very versatile manner. It is particularly advantageous that even with the finest material, ie the smallest fiber particles and when spraying, for example onto a surface, these smallest particles are not released, Rather, they are applied to the surface bound in foam and are therefore harmless and environmentally friendly to process. The effort required for this is low, so that such a method must be regarded as particularly technically advanced.
Besonders vorteilhaft kann auch ein feinstfasriges Fasermaterial wirkungsvoll aufgebracht werden bzw. in Hohlräume hineingeblasen werden, wenn, wie erfindungsgemäß vorgesehen, der Schaum in der Maschine durch intensives Vermischen von Wasser, Luft und einem Spezialschäumer erzeugt und dann dem Dämm-/Isolierstoff zugemischt wird. Dabei ist besonders vorteilhaft, daß bereits ein fertiggestellter Schaum mit dem Dämm- oder Isolierstoff, d.h. also mit den Mineralfasern gemischt wird, so daß die weiter oben beschriebene vorteilhafte Einbindung in das Schaumkissen möglich ist. Dabei wird die Faser praktisch in den fertigen Schaum hineingegeben, von diesem umhüllt, weitergetragen und solange festgehalten, wie dies für den Transport und die Verarbeitung optimal ist. Danach löst sich der Schaum quasi von selbst auf, ohne daß der mitenthaltene Spezialschäumer für den Aushärtungsprozeß bzw. den Isolierprozeß Nachteile hervorbringen würde.It is also particularly advantageous to be able to apply a very fine-fiber material effectively or to blow it into cavities if, as provided according to the invention, the foam is produced in the machine by intensive mixing of water, air and a special foamer and then mixed with the insulation / insulating material. It is particularly advantageous that a finished foam with the insulating or insulating material, i.e. is mixed with the mineral fibers so that the advantageous integration into the foam cushion described above is possible. The fiber is practically put into the finished foam, enveloped by it, carried on and held for as long as is optimal for transport and processing. Thereafter, the foam dissolves almost automatically, without the included special foam for the curing process or the insulation process causing disadvantages.
Eine weitere Ausführung sieht vor, daß Wasser und ein Schäumer unter Zuführung von Luft vermischt und gleichzeitig mit dem Dämm- und Isolierstoff vermengt wird. Je nach Mineralfaser bzw. Isolierstoff und Dämmstoff kann es aber dabei zu einer zu starken Befeuchtung kommen, weil die Gefahr besteht, daß die Fasern den Schäumprozeß beeinflussen. Je nach Art und Größe der Fasern kann dieses Verfahren aber auch wie erwähnt Vorteile mit sich bringen, weil es das Schäumen und Vermischen in einem Arbeitsgang vorsieht.Another embodiment provides that water and a foamer are mixed with the addition of air and at the same time mixed with the insulating and insulating material. Depending on the mineral fiber or insulating material and insulation material, excessive moistening can occur, however, because there is a risk that the fibers will influence the foaming process. Depending on the type and size of the fibers, this process can also have advantages, as mentioned, because it provides foaming and mixing in one operation.
Je nach Anwendungszweck ist die Zugabe von Bindemittel von Vorteil, insbesondere, wenn als Dämm/Isolierstoff Material zum Einsatz kommt, das eine besonders gute Formbeständigkeit aufweisen soll, beispielsweise weil es in Sicherheitsschränken, Schornsteinen, Stahlkaminen, für Geräteauskleidungen o.ä. zum Einsatz kommt. Dann ist es von Vorteil, wenn der Schaum aus dem Bindemittel, Spezialschäumer und Luft erzeugt und dann oder gleichzeitig mit dem Dämm-/Isolierstoff vermengt und ausgetragen wird. Das Bindemittel übernimmt hier die Funktion des Wassers, wobei je nach Art des Bindemittels sogar auch auf den Spezialschäumer verzichtet werden kann, da Bindemittel und Luft gemeinsam das Schaumkissen erbringen, in das dann das Dämm-/Isoliermaterial eingebettet werden kann.Depending on the application, the addition of binders is advantageous, especially if material is used as insulation / insulating material is used, which should have a particularly good dimensional stability, for example because it is in safety cabinets, chimneys, steel fireplaces, for device linings or the like. is used. Then it is advantageous if the foam is generated from the binder, special foamer and air and then or at the same time mixed and discharged with the insulating / insulating material. The binder takes on the function of water here, and depending on the type of binder, the special foamer can even be dispensed with, since the binder and air together produce the foam cushion in which the insulation / insulation material can then be embedded.
In der Regel ist der Anteil an Spezialschäumer geringzuhalten. Erfindungsgemäß ist vorgesehen, daß er mit einem Anteil von 0,5 bis 6 % beigemischt wird, wobei dies im wesentlichen von den Anforderungen an den Schaum bezüglich seiner Stabilität und der Größe seiner Bläschen abhängt. Auch die Größe der einzubindenden Mineralfasern ist mitentscheidend, wobei zweckmäßigerweise vorgesehen ist, daß der Anteil des Spezialschäumers mit Verringerung der Faserabmessungen gesteigert wird, um auf diese Art und Weise die Stabilität vor allem des Schaumes zu erhöhen. Wichtig ist auch, ob das Material anschließend noch von Hand weiterverarbeitet und geformt werden soll, da dann eine entsprechende Optimierung des Schaumes von Vorteil ist. Werden aber einfach Hohlräume ausgespritzt, so kann auch der Anteil an Schäumer verringert werden, da es dabei im wesentlichen um das staubfreie Einbringen der Mineralfasern bzw. des Dämm- und Isolierstoffes geht.As a rule, the proportion of special foamers should be kept low. It is provided according to the invention that it is admixed with a proportion of 0.5 to 6%, which essentially depends on the requirements for the foam with regard to its stability and the size of its bubbles. The size of the mineral fibers to be incorporated is also a decisive factor, it being expediently provided that the proportion of the special foamer is increased with a reduction in the fiber dimensions, in order in this way to increase the stability of the foam in particular. It is also important whether the material should then be further processed and shaped by hand, since then an appropriate optimization of the foam is advantageous. However, if cavities are simply sprayed out, the proportion of foaming agents can also be reduced, since this essentially involves the dust-free introduction of the mineral fibers or the insulating and insulating material.
Zur Durchführung des Verfahrens dient eine Vorrichtung, bei der der Dämm-/Isolierstoff über ein Gebläse oder eine Pumpe durch einen Einblasschlauch herangebracht wird, um dann Bindemittel u.ä. zuzugeben und das Material durch die ausgangsseitige Spritzdüse auszutragen. Zur Durchführung des Verfahrens wird eine solche Vorrichtung erweitert, indem der Einblasschlauch ausgangsseitig als Doppelrohr ausgebildet ist, in das ein Schaumrohr einmündet und dessen Innenrohr mit einstellbar ausgebildeten Schleusen ausgerüstet ist. Bei einer derartigen Ausbildung wird in dem Doppelrohr der in der Maschine erzeugte Schaum über die Schleusen in das Innere des Einblasschlauches bzw. in das Innere des Doppelrohres eingegeben, wo er den Dämm-/Isolierstoff aufnimmt, einbettet und mit diesem zusammen dann über die Düse ausgetragen wird.A device is used to carry out the method, in which the insulation / insulating material is brought in via a blower or a pump through an injection hose, in order to then binders and the like. add and discharge the material through the spray nozzle on the outlet side. To carry out The method expands such a device by designing the inlet hose as a double tube on the outlet side, into which a foam tube opens and the inner tube of which is equipped with adjustable locks. With such a design, the foam produced in the machine is entered in the double pipe through the locks into the interior of the blow-in hose or into the inside of the double pipe, where it receives the insulation / insulating material, embeds it and then discharges it together with it via the nozzle becomes.
Die für eine optimale Einstellung des Schaumes notwendige Luft kann noch nachgemischt werden, wenn das Außenrohr des Doppelrohres wie erfindungsgemäß vorgeschlagen, mehrere zur Luftzuführung dienende, über den Umfang verteilt angeordnete Bohrungen aufweist. Durch diese Bohrungen tritt die Luft je nach Bedarf in den Zwischenraum ein, um dort mit Wasser, Schäumer bzw. Bindemittel durchmischt und zu Schaum verarbeitet zu werden. Dieser Schaum wird dann, wie weiter oben erwähnt, durch die Schleusen in den Innenraum ausgetragen, wo die Durchmischung mit dem Dämm-/Isolierstoff erfolgt. In diesen Bohrungen soll eine Art Rückschlagventil angeordnet werden, so daß durch den Innendruck im Zwischenraum zwischen Außen- und Innenrohr Luft eingesaugt wird, nicht aber den umgekehrten Weg strömen kann.The air required for optimal adjustment of the foam can still be mixed if the outer tube of the double tube, as proposed according to the invention, has a plurality of bores which are arranged around the circumference and are used for air supply. Through these holes, the air enters the intermediate space as required, in order to be mixed with water, foamer or binder and processed into foam. As mentioned above, this foam is then discharged through the locks into the interior, where it is mixed with the insulating / insulating material. A kind of check valve is to be arranged in these bores, so that air is sucked in by the internal pressure in the space between the outer and inner tube, but cannot flow the other way round.
Weiter oben ist bereits darauf hingewiesen worden, daß entweder Wasser oder Bindemittel für die Schaumherstellung zum Einsatz kommt. Von daher wird der Aufbau einerseits erleichtert und die Spritzpistole besser handhabbar, wenn das Schaumrohr, wie erfindungsgemäß vorgesehen, mit einem Bindemittel- oder einem Wasserspeicher verbunden ist. Damit kann durch entsprechende Ventile entweder Bindemittel und/oder Wasser zur Herstellung des Schaumes zugeführt werden, je nachdem, welcher Einsatzzweck für das Endprodukt vorgesehen ist, wobei die Herstellung in der Maschine bzw. dem entsprechend ausgebildeten Schaumrohr erfolgt. Da sowohl das Bindemittel wie auch das Wasser nur in relativ geringen Mengen benötigt wird, kann ein Schlauch geringen Durchmessers verwendet werden, so daß mit der Spritzpistole und den nachgeordneten Schläuchen auch größere Distanzen zur Einblasmaschine überbrückt werden können, so daß die Arbeiten insgesamt dadurch erleichtert sind.It has already been mentioned above that either water or binders are used for foam production. Therefore, the structure is made easier on the one hand and the spray gun is easier to handle if the foam tube, as provided according to the invention, is connected to a binder or a water reservoir. Corresponding valves can be used to supply either binder and / or water for the production of the foam, depending on the intended use for the end product, the production in the machine or the appropriately trained foam pipe. Since both the binding agent and the water are only required in relatively small amounts, a hose of small diameter can be used, so that larger distances to the blowing machine can also be bridged with the spray gun and the downstream hoses, so that the work as a whole is thereby facilitated .
Eine optimale Durchmischung des Materials vor dem Verlassen der Spritzdüse wird sichergestellt, indem zwischen Doppelrohr und Spritzdüse ein Mischschlauch angeordnet ist. In diesen Mischschlauch wird der getrennt hergestellte und mit dem Dämm-/Isolierstoff dann vermischte Schaum noch einmal mit dem Stoff so durchmischt, daß an der Spritzdüse auch wirklich das gewünschte, die kleinsten Faserpartikel einbettende Schaumkissen austritt, um den vorgesehenen Hohlraum auszufüllen oder aber die vorgesehene Fläche zu bedecken.Optimal mixing of the material before leaving the spray nozzle is ensured by arranging a mixing hose between the double pipe and the spray nozzle. In this mixing hose, the foam, which is produced separately and then mixed with the insulating / insulating material, is mixed again with the material in such a way that the desired foam cushion embedding the smallest fiber particles really emerges at the spray nozzle in order to fill the intended cavity or else the intended one Cover area.
Die Erfindung zeichnet sich insbesondere dadurch aus, daß ein Verfahren geschaffen worden ist, mit dem auf überraschende Art und Weise auch feinstfasriges Fasermaterial für Dämm- und Isolierzwecke sicher und staubfrei verarbeitet werden kann. Dabei ist es nicht nur möglich, dieses Material in Hohlräume einzublasen, sondern auch damit Flächen zu bespritzen, auf denen dieses Material dann vorteilhaft haften bleibt. Der hergestellte Spezialschaum, der aus Luft und Wasser oder aus Luft und Bindemittel bzw. auch Schäumer besteht, kann mit der Misch- bzw. Spritzpistole ausgetragen werden, wobei er die Faserpartikel sicher mitnimmt und einbettet. Diese Masse ist dann wiederum überraschend problemlos weiterzubearbeiten, wobei sie vorteilhaft in Formen oder Hohlräume eingefüllt werden kann oder aber auf Decken, Wände und Stahlteile aufgespritzt werden kann, um dann anschließend geglättet zu werden. Der Trägerschaum verschwindet nach einer gewissen Zeit, so daß dann ein optimal festes und vorteilhaftes Formteil entsteht, das die vorgesehene Dämm- oder Isolieraufgabe vorteilhaft erfüllen kann. Für entsprechende Einsatzgebiete als Wärmeisolierung mit Mineralwolle, als Brandschutz oder als Hochtemperaturisolierung mit keramischen Fasern stehen eine Reihe von Bindemitteln zur Verfügung, die den jeweils gewünschten Anforderungen gerecht werden und mit Hilfe des Verfahrens und der Vorrichtung optimal zu verarbeiten sind. Das Verfahren und die Vorrichtung sind somit sehr vielseitig einsetzbar und genügen den besonderen Umweltschutzbedingungen optimal, weil die zu verarbeitenden Mineralfasern und sonstigen Dämm-/Isolierstoffe während des Verarbeitungsprozesses nicht in die Umwelt gelangen können und weil sie nach dem Verarbeiten auch noch optimal als Formteil wirken. Als besonders vorteilhaft ist anzusehen, daß nur eine relativ geringe Wassermenge zugeführt werden muß, so daß ein schnelles Austrocknen des Endmaterials erreicht werden kann. Vorteilhaft ist weiter ein wesentlich verringerter Spritzverlust und ein geringes Raumgewicht, da durch den Schaum ein entsprechend günstiger Aufbau erreicht wird. Auf die staubfreie Verarbeitung sowie die Möglichkeit des Glättens und Verformens des aufgebrachten Materials ist bereits hingewiesen worden.The invention is characterized in particular by the fact that a method has been created with which, in a surprising manner, even fine-fiber material can be processed safely and dust-free for insulation and insulation purposes. It is not only possible to blow this material into cavities, but also to spray surfaces on which this material then advantageously adheres. The special foam produced, which consists of air and water or of air and binding agent or also foamer, can be discharged with the mixing or spray gun, taking the fiber particles with them and embedding them safely. This mass is then surprisingly easy to process further, whereby it can advantageously be filled into molds or cavities or can be sprayed onto ceilings, walls and steel parts in order to then be smoothed. The carrier foam disappears after a certain time, so that then an optimally firm and advantageous molded part is created, which the intended insulation or Isolation task can advantageously perform. A range of binders are available for appropriate applications as thermal insulation with mineral wool, fire protection or high-temperature insulation with ceramic fibers, which meet the respective requirements and can be optimally processed using the method and the device. The method and the device are thus very versatile and optimally meet the special environmental protection conditions because the mineral fibers and other insulation / insulating materials to be processed cannot get into the environment during the processing process and because they also work optimally as a molded part after processing. It is to be regarded as particularly advantageous that only a relatively small amount of water has to be added, so that the end material can dry out quickly. A significantly reduced spray loss and a low density are also advantageous, since the foam achieves a correspondingly favorable structure. Attention has already been drawn to the dust-free processing and the possibility of smoothing and deforming the applied material.

Fig. 1 zeigt eine Einblasmaschine (1) in einfacher Ausfertigung, wobei auf der Vorderseite der Ansaugschlauch (2) und der Einblasschlauch (3) über Anschlüsse mit der Einblasmaschine (1) zu verbinden sind. Weiter sind Steckanschlüsse (4) zu erkennen, über die die verschiedenen Bindemittel oder Wasserzuführungsschläuche mit den in der Einblasmaschine (1) untergebrachten Speichern zu verbinden sind. Weiter sind auch Steckanschlüsse (4) für die elektrische Versorgung der in dem Gehäuse der Einblasmaschine (1) untergebrachten Gebläse vorgesehen. Mit (5) ist eine Spritzdüse angedeutet bzw. der dafür vorgesehene Anschluß, mit (7) die Spritzpistole, wobei Einzelheiten der Fig. 2 zu entnehmen sind.Fig. 1 shows a blowing machine (1) in simple design, with the suction hose on the front (2) and the injection hose (3) are to be connected to the injection machine (1) via connections. Plug connections (4) can also be seen, by means of which the various binders or water supply hoses can be connected to the accumulators accommodated in the blowing machine (1). Plug connections (4) are also provided for the electrical supply to the blowers housed in the housing of the blowing machine (1). (5) indicates a spray nozzle or the connection provided for it, (7) the spray gun, details of FIG. 2 being shown.
Als Spritzpistole (7) dient die aus Fig. 2 ersichtliche Vorrichtung, wobei es sich dabei um ein Rohrstück handelt, in das einmal der Einblasschlauch (3) einmündet und zum anderen das Schaumrohr (6). Vorne an der Spitze ist die Spritzdüse (5) vorgesehen, über die das Material nach dem Mischprozeß ausgetragen wird.The device shown in FIG. 2 serves as the spray gun (7), it being a piece of pipe into which the injection hose (3) opens and the foam pipe (6). The spray nozzle (5) is provided at the front at the tip and is used to discharge the material after the mixing process.
Mittig der Spritzpistole (7) befindet sich ein Doppelrohr (8), in das auch das Schaumrohr (6) einmündet. Das Außenrohr (9) des Doppelrohres (8) weist einen deutlich größeren Durchmesser als das mit den Schleusen (10, 11) ausgerüstete Innenrohr (13) auf. Fig. 3 zeigt, daß die Schleusen (10, 11) über den Umfang des Innenrohres (13) verteilt angeordnet sind und über Schieber (12) teilweise oder ganz verschlossen werden können. Über Einstellschrauben kann die Menge geregelt werden. Der Verschäumungsprozeß kann ggf. im Zwischenraum (17) zwischen Innenrohr (13) und Außenrohr (9) ergänzt werden, um dann einen entsprechend aufgebauten Schaum durch die Schleusen (11, 12) in den Innenraum (18) hineinzubringen. Bei der Schaumherstellung kann im übrigen die Zufuhr von Wasser/Bindemittel und Luftdruck variiert werden. Dadurch ist jederzeit eine Einstellung des Schaumes den Einsatzbedingungen entsprechend möglich.In the middle of the spray gun (7) there is a double pipe (8) into which the foam pipe (6) also opens. The outer tube (9) of the double tube (8) has a significantly larger diameter than the inner tube (13) equipped with the locks (10, 11). Fig. 3 shows that the locks (10, 11) are arranged distributed over the circumference of the inner tube (13) and can be partially or completely closed via slide (12). The quantity can be regulated using adjusting screws. The foaming process can optionally be supplemented in the intermediate space (17) between the inner tube (13) and the outer tube (9) in order then to bring a suitably constructed foam through the locks (11, 12) into the interior (18). The supply of water / binder and air pressure can also be varied during foam production. This means that the foam can be adjusted at any time according to the conditions of use.
Soll zur Beeinflussung des Schaumes noch Luft zugeführt werden, erfolgt dies über die Bohrungen (14, 15) im Außenrohr (9). Diese Bohrungen (14, 15) können durch Rückschlagventile gesichert werden, um das Austreten des Schaumes sicher zu unterbinden und sicherzustellen, daß dieses Material ausschließlich über die Schleusen (11, 12) in den Innenraum (18) hineingebracht wird. Es ist auch denkbar, Bindemittel mit Wasser und Luft sowie Schäumer zu einem entsprechenden Schaum zu verarbeiten.If air is to be added to influence the foam, this is done via the bores (14, 15) in the outer tube (9). These bores (14, 15) can be secured by check valves in order to reliably prevent the foam from escaping and to ensure that this material is brought into the interior (18) exclusively via the locks (11, 12). It is also conceivable to process binders with water and air as well as foaming agents to form a suitable foam.
Die im Innenraum (18) gemischte Masse wird anschließend in einen Mischschlauch (16) hineingefördert, dessen Lage und Ausbildung in Fig. 2 gezeigt und angedeutet ist. In diesem Mischschlauch (16) erfolgt eine weitere und abschliessende Durchmischung von Schaum und Fasern, so daß dann nur optimal eingebettete Fasern über die Spritzdüse (5) die Spritzpistole (7) verlassen können. Diese Masse kann dann, wie bereits erwähnt, problemlos weiterverarbeitet werden.The mass mixed in the interior (18) is then conveyed into a mixing hose (16), the location and design of which is shown and indicated in FIG. 2. A further and final mixing of foam and fibers takes place in this mixing hose (16), so that only optimally embedded fibers can leave the spray gun (7) via the spray nozzle (5). As already mentioned, this mass can then be processed without any problems.
Vorteilhaft ist der um rd. 50 % geringere Wasserverbrauch, ein geringer Spritzverlust (vernachlässigbar), ein geringes Raumgewicht der Masse und vor allem ein völlig staubfreies Spritzen und sonstiges Verarbeiten der Masse.The advantage is around 50% lower water consumption, a low spray loss (negligible), a low density of the mass and above all a completely dust-free spraying and other processing of the mass.
Alle genannten Merkmale, auch die den Zeichnungen allein zu entnehmenden, werden allein und in Kombination als erfindungswesentlich angesehen.All of the features mentioned, including those that can be seen in the drawings alone, are regarded as essential to the invention, alone and in combination.
