The hoods are formed into a self-supporting, stable framework. The drying tower structure consists of lengthwise and crosswise struts.

Description

Die Erfindung betrifft eine Trocknungsanlage zum Trocknen aller rieselfähigen Produkte, insbesondere aber zum Trocknen von Getreide gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a drying system for drying all free-flowing Products, but especially for drying grain according to the generic term of claim 1.

Bei einer solchen Trocknungsanlage wird das zu trocknende Gut in der Regel von oben in einen Trocknungsturm eingebracht, in dem es während des Durchlaufs mittels Warmluft getrocknet wird. Im Trocknungsturm sind eine Vielzahl von Warmluft durchströmter Trocknungsmodule angeordnet, die aus im wesentlichen horizontal verlaufenden, umgekehrt V-förmigen, Firstblechen bestehen, die beabstandet parallel nebeneinander und in mehreren Lagen übereinander so angeordnet sind, daß in der nächst tieferen Lage der First jeweils im Zwischenraum zwischen den Firsten der darüberliegenden Lage angeordnet ist.In such a drying system, the material to be dried is usually from placed in a drying tower at the top, in which it is in transit is dried by means of warm air. In the drying tower are a variety of Warm air through which drying modules are arranged, which essentially consist of horizontally extending, inverted V-shaped, ridge sheets exist spaced parallel next to each other and in several layers one above the other are arranged that in the next lower position of the ridge each in the space is arranged between the ridges of the overlying layer.

Die Firstbleche sind an ihren stirnseitigen Enden in Stirnblechen befestigt. Das Trocknungsgut läuft auf die Oberseite eines Firstbleches, wird dort seitlich nach unten abgeleitet und fällt auf das Firstblech der nächsten oder übernächsten darunterliegenden Lage von Firstblechen. Die mit Warmluft durchströmten Firstbleche ergeben bei sinnvoller Anordnung eine gleichmäßige Warmluftverteilung über den Modulquerschnitt.The ridge sheets are fastened in end sheets at their front ends. The Dried material runs on the top of a ridge sheet and is laterally there derived below and falls on the ridge sheet of the next or the next underlying layer of ridge sheets. The flow of warm air With a sensible arrangement, ridge sheets result in an even distribution of warm air over the module cross section.

An zwei Seiten des Trockenturms sind deshalb weitere Türme vorgesehen, um die durch den Trockenturm geleitete Warmluft zu- und abzuführen. Der Turm zum Zuführen der Warmluft wird dabei als Zulufthaube und der Turm zum Abführen der Luft als Ablufthaube bezeichnet. Das Temperaturgefälle zwischen Zuluftseite und Abluftseite hängt vom beabsichtigten Trocknungsvermögen ab, und darüber hinaus vom Grad des Wärmeverlustes durch die Außenhaut der Trockenanlage, welche wiederum von der Luftdichtigkeit als auch der Isolierung bzw. den Wärmedurchgangskoeffizienten dieser Außenhaut abhängt. Die Frage, ob und in welchem Maß die Außenhaut isoliert werden muß, hängt jedoch nicht ausschließlich wirtschaftlich von den Kosten des Energielieferanten ab, sondern von der Forderung nach einer gleichmäßigen Temperaturverteilung und damit auch von einem gleichmäßigen Trocknungsverlauf über den gesamten Querschnitt der Trockensäule.Additional towers are therefore provided on two sides of the drying tower supply and discharge warm air conducted through the drying tower. The tower to the The supply of warm air is used as a supply air hood and the tower for removing the Air referred to as an exhaust hood. The temperature gradient between the supply air side and Exhaust side depends on the intended drying capacity, and beyond on the degree of heat loss through the outer skin of the drying system, which again from the airtightness as well as the insulation or the Thermal transmittance depends on this outer skin. The question of whether and in the degree to which the outer skin has to be insulated does not, however, depend exclusively economically on the costs of the energy supplier, but on the demand after an even temperature distribution and thus also from one uniform drying process over the entire cross section of the Dry column.

Zudem ist die Vermeidung von Kondenswasser speziell in der Ablufthaube als ein Grund für die Forderung nach einer Isolierung anzusehen.In addition, the avoidance of condensed water is especially important in the exhaust hood To see the reason for the demand for insulation.

Bei bisher bekannten Trockenanlagen besteht der Trockenturm aus aufeinander gestapelten Trockenmodulen. Die Zuluft- und Ablufthaube bestehen aus vielen untereinander verbundenen Blechteilen mit Aussteifungselementen, welche außen isoliert und mit dünnen Fassadenblechen verkleidet werden können.In previously known drying plants, the drying tower consists of one another stacked drying modules. The supply air and extract air hoods consist of many interconnected sheet metal parts with stiffening elements, which outside insulated and can be clad with thin facade sheets.

Die übereinander angeordneten Trockenmodule und deren Zuluft- und Ablufthauben sind dabei zwar an Stützen, meist aus Stahlprofilen, befestigt, jedoch stellen diese Stahlstützen kein selbsttragendes Gerüst dar, sondern ergeben erst im Verbund mit den Trockenmodulen und der äußeren Verblechung ein standfestes Ganzes. Eine statische Berechnung dieser Bauweise und erst recht deren dynamische Belastungen war nie möglich, sondern derartige Trocknungsanlagen wurden immer nur nach Erfahrungswerten ausgelegt. Erst recht war es nicht möglich, schwere Elemente wie Entstaubungsanlagen im oberen Bereich der Trockungsanlage anzuordnen. Statt dessen wurde der untere Teil, also der auf dem Untergrund aufsitzende Bereich, aus einem sehr stabilen Untergestell aus Stahlprofilen erstellt, und darin die schweren elektrischen und beweglichen mechanischen Elemente (Lüfter, Motoren, Staubabscheider, Lufterhitzer) untergebracht. Erst auf diesem Grundgestell wurde in integrierter Bauweise die Trocknungsanlage erstellt.The stacked drying modules and their supply and exhaust hoods are attached to supports, usually made of steel profiles, but they do Steel supports are not a self-supporting scaffold, but only result in conjunction with the drying modules and the external cladding a stable whole. A static calculation of this construction and especially its dynamic Loads were never possible, but such drying systems have always been designed only based on experience. All the more, it was not possible to make serious Elements such as dedusting systems in the upper area of the drying system to arrange. Instead, the lower part, that is, the one on the underground sitting area, created from a very stable base made of steel profiles, and in it the heavy electrical and mobile mechanical elements (Fans, motors, dust separators, air heaters). Only on this The drying rack was built in an integrated design.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine Trockenanlage sowie ein Verfahren zu Ihrer Herstellung zu schaffen, bei der die Trockenmodule schwächer ausgelegt werden können. Außerdem ist es die Aufgabe der vorliegenden Erfindung, eine Trockenanlage zu schaffen, die statisch und dynamisch berechenbar und wesentlich stabiler ist.It is therefore the object of the present invention, a drying plant and a To create processes for your manufacture where the drying modules are weaker can be interpreted. It is also the object of the present invention to create a drying system that is statically and dynamically predictable and is much more stable.

Gelöst wird diese Aufgabe gemäß der Erfindung durch die im Anspruch 1 angegebenen Merkmale. Zweckmäßige Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved according to the invention by that in claim 1 specified characteristics. Appropriate embodiments of the invention result from the subclaims.

Erfindungsgemäß ist zumindest der Trockenturm aus einem Gerüst aus Längs- und Querstreben gebildet, das auch ohne eingesetzte Trockenmodule selbsttragend und stabil ist. Zum Tragen der Trockenmodule sind am Gerüst entsprechende Verbindungs- bzw. Haltemittel vorgesehen.According to the invention, at least the drying tower consists of a frame made of longitudinal and Cross struts formed, the self-supporting and even without the use of drying modules is stable. To carry the drying modules, there are corresponding ones on the scaffolding Connection or holding means provided.

Die Zuluft- und Ablufthaube weisen vorzugsweise ebenfalls ein selbsttragendes, stabiles Gerüst und eine Aussenverkleidung auf.The supply air and exhaust air hood preferably also have a self-supporting, stable scaffolding and an outer cladding.

Die Trockenanlage wird vorzugsweise an der Außenseite mit Paneelen verkleidet, die, falls gewünscht, eine Isolationsschicht aufweisen können. Vorzugsweise werden Sandwichpaneele verwendet, die dreischichtig aufgebaut sind und aus einer dünnen inneren und äußeren Wandung, meist aus Metall, und einem inneren Isolierstoff bestehen.The drying system is preferably clad on the outside with panels, which, if desired, can have an insulation layer. Preferably be Sandwich panels are used, which have a three-layer structure and a thin one inner and outer walls, mostly made of metal, and an inner insulating material consist.

Wegen der relativ hohen Temperaturen in der Trockenanlage sollte jedoch kein geschäumtes Isoliermaterial, sondern (gepreßte) Mineralwolle verwendet werden. Gepresste Mineralwolle bietet nicht nur eine Wärmeisolierung, sondern gleichzeitig einen Brandschutz. Da die Beplankung mit derartigen Platten vorzugsweise über die gesamte Außenfläche der Trocknungsanlage durchgeht, stellt die so durchgehende Paneelbeplankung eine Brandschutzbarriere dar, die es ermöglicht, die Trocknungsanlage leer an brennbaren Gegenständen, etwa an Gebäuden, anzuordnen, als bei Verwendung analoger Sandwichpaneele mit geschäumtem Isoliermaterial, welches einen niedrigen Flammpunkt besitzt.Because of the relatively high temperatures in the drying plant, however, none should foamed insulating material, but (pressed) mineral wool can be used. Pressed mineral wool not only provides thermal insulation, but at the same time fire protection. Since the planking with such panels is preferably carried out over the the entire outer surface of the drying system passes through, so the continuous Panel planking represents a fire protection barrier that enables the Drying system empty on flammable objects, such as buildings, to be arranged than when using analog sandwich panels with foamed Insulating material with a low flash point.

Wegen des mehrschichtigen Aufbaus der Paneele und der flächigen, meist geklebten, Verbindung zwischen den einzelnen Schichten der Paneele besitzen die Sandwichpaneele eine hohe Eigensteifigkeit, und vergrößern die Belastbarkeit des Traggerüstes zusätzlich, wenn die Paneele beispielsweise mittels selbstschneidender Schrauben von außen auf dem Gerüst befestigt werden.Because of the multilayer structure of the panels and the flat, mostly glued, connection between the individual layers of the panels possess the Sandwich panels have high inherent rigidity, and increase the resilience of the Supporting structure additionally if the panels, for example, by means of self-tapping screws can be attached to the frame from the outside.

Die Innenwandung der Sandwichpaneele besteht vorzugsweise nicht aus Stahlblech, sondern insbesondere aus Aluminium oder Edelstahl, um vor allem an der Ablufthaube eine Korrosion zu vermeiden. Die Außenwandung kann aus verzinktem Stahlblech oder ebenfalls Alu-Blech oder Edelstahl bestehen.The inner wall of the sandwich panels is preferably not made of Sheet steel, but in particular made of aluminum or stainless steel, especially to to prevent corrosion of the exhaust hood. The outer wall can be made galvanized steel sheet or also aluminum sheet or stainless steel.

Das Traggerüst der Trockenanlage wird vorzugsweise komplett mit den Sandwichpaneelen verkleidet, die horizontal verlaufend über vorzugsweise die gesamte Länge bzw. Breite der Trockenanlage angeordnet sind, so daß nur an den Ecken Stoßkanten vorhanden sind. Die Stoßkanten selbst können z. B. mit Eckprofilen aus Aluminium abgedeckt werden.The supporting structure of the drying plant is preferably completely with the Sandwich panels covered, which preferably run horizontally across the entire length or width of the drying system are arranged so that only the Corners butt edges are present. The abutting edges themselves can e.g. B. with Corner profiles made of aluminum are covered.

Eine besonders einfache und schnelle Montage der Paneele kann durch eine Nut-Feder-Verbindung erreicht werden, indem die eine Längskante des Paneels eine nutartige in Längsrichtung durchgehende Vertiefung und die gegenüberliegende Kante einen analog zur Nut geformten, in Längsrichtung ebenfalls durchgehenden Fortsatz aufweist. Die Nut-Feder-Verbindung kann ebenfalls aus Metall, insbesondere Metallprofil, bestehen, das vorzugsweise von der Außenwandung thermisch getrennt ist. Neben der schnellen Montage bieten solche Sandwichelemente eine sehr gute Wärmeisolierung und hohe Luftdichtheit. Die Trockenanlage kann deshalb mit sehr geringem Energieeinsatz betrieben werden und ermöglicht somit eine wirtschaftliche Trocknung.A particularly simple and quick installation of the panels can be achieved with a tongue and groove connection can be achieved by the one longitudinal edge of the panel groove-like recess in the longitudinal direction and the opposite Edge of a shape similar to the groove, also continuous in the longitudinal direction Has extension. The tongue and groove connection can also be made of metal, in particular metal profile, which are preferably from the outer wall is thermally separated. In addition to quick assembly, such offer Sandwich elements have very good thermal insulation and high airtightness. The The drying system can therefore be operated with very little energy and thus enables economical drying.

Eine weitere Verbesserung des Wirkungsgrades kann erreicht werden, wenn ein Teil der Warmluft nach Durchlaufen des Trockenturmes dem Warmluftkreislauf zurückgeführt wird. Zu diesem Zweck wird ein Teil der Warmluft, vorzugsweise etwa 30 %, von der Ablufthaube in die Zulufthaube zurückgeleitet. Das Rückführen der Warmluft erfolgt vorzugsweise durch den unteren Teil des Trockenturms. A further improvement in efficiency can be achieved if a part the warm air after passing through the drying tower the warm air circuit is returned. For this purpose, part of the warm air, preferably about 30%, returned from the exhaust hood to the supply hood. The return of the Warm air is preferably drawn through the lower part of the drying tower.

Der Trockenturm umfaßt neben den Trockenmodulen Kühlmodule, die in einer unteren Modulebene angeordnet sind. Die Kühlmodule werden mit Kaltluft gekühlt, die sich beim Durchlaufen des Kühlmoduls erwärmt. Die erwärmte Kühlluft kann wiederum dem Warmluftkreislauf zugeführt werden, um somit den Wirkungsgrad der Anlage zu erhöhen.The drying tower includes cooling modules in addition to the drying modules are arranged at the lower module level. The cooling modules are cooled with cold air, which heats up as it passes through the cooling module. The heated cooling air can in turn be fed to the hot air circuit in order to increase the efficiency of the Increase plant.

Die Kühlluft wird vorzugsweise von der Seite der Ablufthaube in Richtung der Zulufthaube, also in entgegengesetzter Richtung zur Warmluft, geleitet und wird nach ihrer Erwärmung der Zuluft wieder zugegeben. Durch verschließbare Öffnungen in der Zulufthaube kann die Kühlzone in ihrer Größe an die verschiedenen Produkte angepaßt werden.The cooling air is preferably from the side of the exhaust hood in the direction of Supply air hood, i.e. in the opposite direction to the warm air, is directed and is added to the supply air after it has warmed up. With lockable Openings in the supply air hood can match the size of the cooling zone can be adapted to different products.

Wegen des stabilen, selbsttragenden Gerüsts können sämtliche Zusatzeinrichtungen, wie z. B. Gebläse und Ventilatoren an dem Gerüst befestigt werden und müssen nicht mehr, wie bislang, auf eigens errichteten Gestellen montiert werden. Außerdem ist es Dank des stabilen, selbsttragenden Gerüsts möglich, eine Entstaubungsanlage zum Entstauben der Abluft in die Trockenanlage zu integrieren.Because of the stable, self-supporting framework, everyone can Additional devices, such as. B. fans and fans attached to the scaffold are and no longer have to, as previously, on specially constructed racks to be assembled. It is also thanks to the stable, self-supporting frame possible, a dedusting system for dedusting the exhaust air into the drying system to integrate.

Die Entstaubungsanlage kann insbesondere in einem separaten Raum im oberen Bereich der Trocknungsanlage angeordnet werden, wenn die Tragfähigkeit des Gerüsts entsprechend ausgelegt ist. Dies hat außerdem den Vorteil, daß kein zusätzlicher externer Entstaubungsraum vorgesehen sein muß und insbesondere keine zusätzliche Grundfläche für die Entstaubungsanlage erforderlich ist und wegen der Höhe der Positionierung und der Paneelverkleidung bereits ein gewisser Lärmschutz sowie Brandschutz erzielt wird. Auch wenn alle sonstigen elektrischen Motoren vorzugsweise in einen abgetrennten, von staubhaltigen Luftströmen freien Raum im unteren Teil des Trockners angeordnet werden, weist dies den Vorteil auf, daß auch hier Lärm- und Brandschutz durch die Verkleidung besteht, sowie alle gültigen Ex-Vorschriften eingehalten werden können.The dedusting system can in particular be in a separate room in the upper Area of the drying plant can be arranged if the load capacity of the Scaffolding is designed accordingly. This also has the advantage that none additional external dedusting room must be provided and in particular no additional floor space is required for the dedusting system and because of the height of the positioning and the panel cladding already a certain Noise protection and fire protection is achieved. Even if all other electrical Motors preferably in a separate, free of dusty air streams Space in the lower part of the dryer, this has the advantage that here too there is noise and fire protection through the cladding, as well as all Ex regulations can be observed.

Hinsichtlich des Aufbaus der Trocknungsanlage sind wegen der Eigenstabilität des Traggerüstes zwei unterschiedliche Vorgehensweisen möglich: Entweder wird zuerst das Traggerüst vollständig aufgebaut, und anschließend darin die Trocknungsmodule befestigt, wofür die Stabilität des Traggerüstes ausreicht und berechnet ist. Erst anschließend wird die Außenbeplankung mittels Paneelen aufgebracht.With regard to the structure of the drying system are due to the inherent stability of the Two different approaches are possible: Either first the scaffolding is fully assembled, and then the Drying modules attached, for which the stability of the supporting structure is sufficient and is calculated. Only then is the external planking made using panels applied.

Die andere und schnellere Methode besteht darin, vormontierte Baueinheiten, beispielsweise stockwerkartig übereinander anzuordnende Einheiten, zusammenzusetzen, die jeweils aus dem Traggerüst, den darin angeordneten Modulen und ggf. darin enthaltenen weiteren Elementen wie Rohrleitungen, Luftführungen etc. besteht. Diese vormontierten Einheiten können beispielsweise mittels Kran übereinandergesetzt und verschraubt und auf diese Art und Weise die Trocknungsanlage sehr schnell aufgebaut werden.The other and faster method is to use pre-assembled units, for example units to be stacked on top of each other, put together, each from the supporting structure, the arranged therein Modules and any other elements they contain, such as pipes, Air ducts etc. exist. These pre-assembled units can, for example placed and screwed on top of each other by crane and in this way the Drying system can be set up very quickly.

Dabei ist es insbesondere auch möglich, die in der untersten Etage des Traggerüstes stehenden großvolumigen Aggregate wie Lufterhitzer, Lüfter, Motoren auf dem Untergrund vorab aufzustellen und zu fixieren, und danach erst das Traggerüst dieser untersten Etage auf dem Untergrund aufzusetzen.It is in particular also possible that in the lowest floor of the Supporting standing large-volume units such as air heaters, fans, motors to set up and fix on the surface in advance, and only after that Support frame of this lowest floor to put on the ground.

Die Beplankung mit Sandwichpaneelen erfolgt vorzugsweise erst nach vollständigem Aufbau der Trocknungsanlage als letzter Schritt. Denkbar ist jedoch auch bereits eine fertige Beplanung der einzelnen, vormontierten Einheiten vor deren Zusammensetzung, wobei dann lediglich die horizontalen Stoßfugen dicht verkleidet werden müßten, beispielsweise durch übergreifende Profilabdeckungen.The paneling with sandwich panels is preferably done only after complete construction of the drying system as the last step. However, it is conceivable also a ready planning of the individual, pre-assembled units their composition, then only the horizontal butt joints tight would have to be disguised, for example by overlapping profile covers.

Die Erfindung wird nachstehend anhand der Fig. 1 bis 4 beispielhaft näher erläutert.The invention is explained in more detail below with reference to FIGS. 1 to 4.

Die in Fig. 1 gezeigte Trockenanlage 1 umfaßt drei Türme 2, 3, 4, von denen der eigentliche Trockenturm 3 in der Mitte angeordnet ist. Am oberen Ende des Trockenturms 3 wird das zu trocknende Gut über eine Zufuhreinrichtung 5 in den Trockenturm eingebracht.The drying plant 1 shown in Fig. 1 comprises three towers 2, 3, 4, of which the actual drying tower 3 is arranged in the middle. At the top of the Drying tower 3 is the material to be dried via a feed device 5 in the Drying tower introduced.

Die Trockenanlage umfaßt weiterhin eine Zulufthaube 2 und eine Ablufthaube 4, die an gegenüberliegenden Seiten des Trockenturms 3 angeordnet sind. Die Hauben 2, 4 dienen zum Zuführen bzw. Abführen von Warmluft, die durch Trockenmodule in den dazwischen liegenden Trockenturm 3 geleitet wird. Die mit Feuchtigkeit gesättigte Abluft wird schließlich zum Großteil durch einen Luftauslaß 6 ausgeblasen.The drying system further comprises an inlet hood 2 and an exhaust hood 4, the are arranged on opposite sides of the drying tower 3. The hoods 2, 4 are used for supplying and removing warm air, which is generated by drying modules the intermediate drying tower 3 is passed. The one with moisture saturated exhaust air is finally largely through an air outlet 6th blown out.

Ein kleinerer Teil der Abluft wird im unteren Bereich der Trockenanlage 1 von der Ablufthaube 4 zur Zulufthaube 2 zurückgeleitet und in einem Luftkreislauf zurückgeführt.A smaller part of the exhaust air is in the lower area of the drying system 1 from the Exhaust hood 4 returned to the intake hood 2 and in an air circuit recycled.

Der Trockenturm 3 umfaßt neben den Trockenmodulen (nicht gezeigt) auch ein Kühlmodul, das zum Kühlen des erwärmten Trockengutes dient. Das Kühlen des Trockengutes erfolgt mittels Kaltluft, die von der Ablufthaube in Richtung der Zulufthaube durch das Kühlmodul geleitet und dabei erwärmt wird. Die erwärmte Kühlluft wird zumindest teilweise in die Zulufthaube ausgeblasen und damit dem Warmluftkreislauf zugeführt.The drying tower 3 also includes a drying module (not shown) Cooling module, which serves to cool the heated dry goods. Cooling the Dry goods are carried out by means of cold air flowing from the exhaust hood towards the Supply air hood is routed through the cooling module and heated. The warmed Cooling air is at least partially blown into the supply air hood and thus the Warm air circuit supplied.

Zumindest der Trockenturm 3 der Trockenanlage 1 besteht aus dem in Fig. 2 gezeigten Traggerüst. Das Traggerüst ist im wesentlichen aus Längsstreben 14 und Querstreben 15 gebildet, die durch diagonal angeordnete Zugstäbe 16 in üblicher Weise auf Druck beansprucht werden. At least the drying tower 3 of the drying system 1 consists of the one in FIG. 2 shown scaffolding. The support structure is essentially made of longitudinal struts 14 and Cross struts 15 formed by diagonally arranged tension rods 16 in the usual Way to be stressed.

An seinen Außenseiten ist das Traggerüst mit Paneelen 17 verkleidet, die in einzelnen horizontalen Bahnen übereinandergeschichtet sind und die Trockenanlage 1 komplett bedecken.On its outer sides, the supporting structure is clad with panels 17, which in individual horizontal tracks are stacked and the Cover drying unit 1 completely.

Fig. 3 zeigt eine Trockenanlage mit dem Trockenturm 3 und den Zuluft- bzw. Ablufthauben 2, 4 im Querschnitt, bei der die Paneele jeweils horizontal über die gesamte Länge bzw. Breite der Trockenanlage 1 verlaufen, so daß nur an den Ecken Stoßkanten vorhanden sind. Dadurch wird eine hohe Luftdichtheit und ferner eine gepflegte Außenansicht der Anlage erreicht.Fig. 3 shows a drying system with the drying tower 3 and the supply air or Exhaust hoods 2, 4 in cross section, in which the panels are each horizontally across the entire length or width of the drying system 1, so that only the Corners butt edges are present. This ensures high airtightness and further achieved a neat exterior view of the facility.

Fig. 4 zeigt eine Schnittansicht eines Sandwichpaneels 17, das vorzugsweise als Außenverkleidung verwendet wird. Das Paneel 17 ist dreischichtig aufgebaut, mit einer Innen- 9 und einer Außenwandung 10 und einer dazwischen liegenden Isolationsschicht 11. Die Isolationsschicht 11 besteht wegen der in der Trockenanlage auftretenden hohen Temperaturen nicht aus geschäumtem Kunststoff, sondern z. B. aus Mineralwolle. Die Innenwandung 9 des Paneels 17 besteht aus Aluminium oder Edelstahl, um einer Korrosion vorzubeugen. Die vertikalen Stoßkanten der Paneelbahnen 17 sind mit Eckprofilen 19 aus z.B. Aluminium abgedeckt.Fig. 4 shows a sectional view of a sandwich panel 17, which is preferably is used as external cladding. The panel 17 is constructed in three layers, with an inner wall 9 and an outer wall 10 and an intermediate wall Insulation layer 11. The insulation layer 11 exists because of the Drying system occurring high temperatures not from foamed Plastic, but z. B. from mineral wool. The inner wall 9 of the panel 17 is made of aluminum or stainless steel to prevent corrosion. The vertical abutting edges of the panel sheets 17 are made with corner profiles 19 from e.g. Aluminum covered.

Die Sandwichpaneele 17 haben außerdem zwei, eine an der Außenhaut / eine an der Innenhaut, horizontal verlaufende Nut-Feder-Verbindungen, die ebenfalls aus Metall bestehen und thermisch voneinander getrennt sind. Die Nut-Feder-Verbindung 18 besteht aus einer entlang einer Längskante des Paneels 17 durchgehenden nutartigen Vertiefung 18a in einer Schmalseite des Paneels, und einem analog geformten, in die Vertiefung 18a des nächsten Paneeles hineinpassenden, in Längsrichtung durchgehenden Vorsprung 18b an der gegenüberliegenden Schmalseite des Paneels 17. Derart ausgestattete Paneele 17 können einfach und schnell montiert werden und bieten eine sehr gute Wärmeisolierung. The sandwich panels 17 also have two, one on the outer skin / one the inner skin, horizontally running tongue and groove connections, which are also made of Metal and are thermally separated. The tongue and groove connection 18 consists of a along a longitudinal edge of the panel 17th continuous groove-like recess 18a in a narrow side of the panel, and an analog shaped one, in the recess 18a of the next panel fitting, in the longitudinal direction continuous projection 18b on the opposite narrow side of the panel 17. Such equipped panels 17 can be installed easily and quickly and offer a very good one Thermal insulation.
