Description

Die Erfindung betrifft eine Vorrichtung zur Trocknung von Raumluft mittels eines mobilen Trocknungsgerätes nach dem Oberbegriff des Anspruchs 1. Derartige Vorrichtungen werden benötigt, wenn feuchtigkeits- und wassergeschädigte Dämmschichten, Hohlräume und Isolationen getrocknet werden sollen, um z. B. einen neu erstellten Bau möglichst schnell benutzen zu können, oder um Feuchtigkeitsschäden an bestehenden Bauten schnell beheben zu können.The invention relates to a device for drying room air by means of a mobile drying device according to the preamble of claim 1. Such devices are needed when damp and water-damaged insulation layers, cavities and insulation to be dried to z. B. to be able to use a newly created construction as quickly as possible, or to be able to fix moisture damage to existing buildings quickly.

Wenn z. B. Wasser aus einer Wasserleitung oder einer Heizungsleitung ausgetreten ist, oder es andere Arten von Überschwemmungen gegeben hat, z. B. in Küchen, Bädern, oder durch äußere Einwirkungen, ist es erforderlich, die Bodenschichten, insbesondere unter einem Estrich, schnell zu entfeuchten. Es gibt im Wesentlichen zwei Verfahren zur Trocknung von Bodenschichten. Beim Überdruckverfahren wird trockene erwärmte Luft durch spezielle Öffnungen in die Dämmschicht eingeblasen. Die eingeblasene Luft nimmt Feuchtigkeit aus dem Dämmmaterial auf und entweicht über Randfugen und Entlastungsbohrungen in dem betreffenden Raum und kann mittels aufgestellter Trocknungsgeräte getrocknet werden. Durch diesen Kreislauf wird eine Austrocknung der Bodenschicht bis zur materialspezifischen Ausgleichsfeuchte erreicht.If z. B. Water has leaked from a water pipe or a heating pipe, or there have been other types of floods, z. As in kitchens, bathrooms, or by external influences, it is necessary to quickly dehumidify the soil layers, especially under a screed. There are essentially two methods for drying soil layers. In the overpressure method, dry heated air is blown through special openings in the insulation layer. The injected air absorbs moisture from the insulating material and escapes via edge joints and relief holes in the room in question and can be dried using installed drying equipment. Through this cycle, a dehydration of the soil layer is achieved up to the material-specific compensation moisture.

Beim Unterdruckverfahren wird der Vorgang umgekehrt betrieben. Hierbei wird mittels Vakuumturbinen feuchte Luft aus einer Dämmschicht herausgesaugt. Das entstehende Vakuum zieht über spezielle Bohrungen oder geöffnete Randfugen mittels eines Trocknungsgerätes getrocknete Raumluft in die Dämmschicht ein, so dass der Feuchtegehalt der Dämmschicht verringert werden kann.In the vacuum process, the process is reversed. In this case, moist air is sucked out of an insulating layer by means of vacuum turbines. The resulting vacuum draws in through special holes or open edge joints by means of a drying device dried room air in the insulating layer, so that the moisture content of the insulating layer can be reduced.

Eine einfachere Trocknungsmöglichkeit besteht in der Verwendung von Lüftern, welche heiße Luft in das zu trocknende Gebiet einblasen. Das Verfahren ist jedoch nur auf solche Fälle beschränkt, in denen die zugeführte Luft sehr trocken ist, da anderenfalls der Wirkungsgrad erheblich verringert ist.A simpler drying option is the use of fans, which inject hot air into the area to be dried. However, the method is limited only to cases in which the supplied air is very dry, otherwise the efficiency is significantly reduced.

Es sind auch Kondensationstrockner bekannt, die nach dem Prinzip eines Kältetrockners arbeiten, bei denen die Entfeuchtung durch Kondensatableitung der Feuchte in einem geschlossenen Luftkreislauf erreichbar ist.There are also known condensation dryers, which operate on the principle of a refrigeration dryer, in which the dehumidification can be achieved by Kondensatableitung the moisture in a closed air circuit.

Schließlich sind Adsorptionstrockner bekannt, bei denen die Prozessluft des Gerätes über eine Adsorptionseinrichtung bis auf 2 - 4% relativer Feuchte erniedrigt wird. Solche Adsorptionstrockner weisen einen hohen Wirkungsgrad bei niedrigen Temperaturen auf.Finally, adsorption dryers are known in which the process air of the device is lowered by an adsorption device to 2 - 4% relative humidity. Such adsorption dryers have a high efficiency at low temperatures.

Aus der DE 695 11 895 ist eine Vorrichtung zur Trocknung von Bodenschichten bekannt, welche es bei hohem Luftdruck erlaubt, eine wassergeschädigte Bodenschicht zu durchlüften und zu trocknen. Die Einrichtung weist einen Trocknungsrotor auf, welcher die hindurchgeführte Luft trocknet, wobei die im Trocknungsrotor aufgenommene Feuchtigkeit durch eine gegenläufige Strömung extern abgegeben werden kann.From the DE 695 11 895 a device for drying of soil layers is known which allows at high air pressure to ventilate a water-damaged soil layer and to dry. The device has a drying rotor, which dries the air passed through, wherein the moisture absorbed in the drying rotor can be externally discharged by an opposite flow.

Die Vorrichtung ist als mobiles Trocknungsgerät ausgeführt, das einen Ansaugstutzen und einen Auslassstutzen enthält. Ein erstes Gebläse saugt Raumluft über den Ansaugstutzen in das Gerät und durch den Trocknungsrotor. Ein Teil der durch den Trocknungsrotor geführten Luft wird im Gegenstrom nach Aufheizung in einer Heizeinrichtung durch den Trocknungsrotor zurückgeführt und an die Außenatmosphäre abgegeben. Der andere Teil der durch den Trocknungsrotor geführten Luft wird über einen Verdichter an einem Auslass geleitet, und dem zu trocknenden Bodenbereich zugeführt, wobei die in den Verdichter eintretende Luft zuvor den Verdichtermotor umströmt und dabei erwärmt wird.The device is designed as a mobile drying device, which includes an intake manifold and an outlet. A first blower sucks room air through the intake manifold into the unit and through the drying rotor. Part of the air guided through the drying rotor is returned in countercurrent after heating in a heater through the drying rotor and discharged to the outside atmosphere. The other part of the guided through the drying rotor air is passed through a compressor at an outlet, and fed to the bottom area to be dried, wherein the air entering the compressor before the compressor motor flows around and is heated.

Bei dieser Einrichtung wird die Prozessluft mittels zweier Lüfter befördert, nämlich einem ersten Lüfter, der die Prozessluft durch den Trocknungsrotor fördert und einen zweiten Lüfter, der die Verdichtung der Prozessluft übernimmt. Da der Wirkungsgrad des Regenerationsschritts zur Rückspülung des Trocknungsrotors unmittelbar von der Temperatur der durchströmenden Luft abhängt, ist es erforderlich, die Regenerationsluft aufzuheizen. Hierzu dient bei dieser bekannten Einrichtung eine gesonderte Heizung. Die zusätzliche Aufheizung der Prozessluft über die Kühlung des Verdichterlüfters bewirkt, dass die aus dem Trocknungsgerät austretende Luft zur Erwärmung eines zu trocknenden Raumes führt, die bei Dauerbetrieb und bei relativ hohen Umgebungstemperaturen zu Schäden an Möbeln und anderen Einrichtungen des Raumes führen kann, welche nicht hinnehmbar sind. Die Einsatzmöglichkeiten dieses Gerätes sind daher beschränkt.In this device, the process air is conveyed by means of two fans, namely a first fan, which conveys the process air through the drying rotor and a second fan, which takes over the compression of the process air. Since the efficiency of the regeneration step for backwashing the drying rotor depends directly on the temperature of the air flowing through, it is necessary to heat the regeneration air. For this purpose, a separate heating is used in this known device. The additional heating of the process air via the cooling of the compressor fan causes the air emerging from the drying device causes heating of a room to be dried, which can cause damage to furniture and other equipment of the room during continuous operation and at relatively high ambient temperatures, which are unacceptable. The applications of this device are therefore limited.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zur Trocknung von Raumluft mittels eines mobilen Trocknungsgerätes anzugeben, welche mit relativ niedrigen Prozesslufttemperaturen arbeitet und die energieeffizient ausgeführt ist.The invention is therefore based on the object of specifying a device for drying room air by means of a mobile drying device, which operates at relatively low process air temperatures and which is designed to be energy-efficient.

Des Weiteren soll die erfindungsgemäße Vorrichtung in der Lage sein, sowohl im Unterdruck- als auch im Überdruckverfahren betrieben zu werden.Furthermore, the device according to the invention should be able to be operated both in the vacuum and in the overpressure method.

Diese Aufgabe wird durch die im Anspruch 1 angegebene Erfindung gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in Unteransprüchen angegeben.This object is achieved by the invention defined in claim 1. Advantageous developments of the invention are specified in subclaims.

Gemäß dem kennzeichnenden Merkmal des Anspruchs 1 ist die Vorrichtung zur Trocknung von Raumluft dadurch gekennzeichnet, dass der Trocknungsrotor mit einem Ansaugstutzen des Trocknungsgerätes und mit dem ersten Gebläse verbindbar ist, wobei das erste Gebläse als Hochdruckgebläse ausgebildet ist, und dass das zweite Gebläse mit einem Einlass für Raumluft in Verbindung-steht und der vom zweiten Gebläse erzeugte Luftstrom zur Kühlung des Hochdruckgebläses über dessen Gehäuse geführt und dem Regenerationseinlass des Trocknungsrotors zugeleitet wird, von dem der Luftstrom über einen Gehäuseauslass aus dem Trocknungsgerät abgeleitet wird.According to the characterizing feature of claim 1, the device for drying room air is characterized in that the drying rotor with an intake manifold of the drying device and the first blower is connectable, wherein the first blower is designed as a high-pressure blower, and that the second blower with an inlet communicates for room air and the air flow generated by the second blower for cooling the high pressure blower is guided over the housing and the regeneration inlet of the drying rotor is fed, from which the air flow is discharged via a housing outlet from the drying device.

Die über den Gehäuseeinlass zugeführte Raumluft wird dabei ohne Verwendung des zweiten Gebläses unmittelbar durch den Trocknungsrotor geleitet und von diesem unmittelbar dem ersten Gebläse zugeführt, von dem die Luft in verdichteter Form in die zu trocknende Bodenschicht geleitet werden kann. Die Regeneration des Rotors erfolgt mittels Durchleitung von Raumluft, welche über einen zweiten Lüfter zugeführt wird, dessen Luftstrom über das Gehäuse des ersten Lüfters und von dort dem ersten Regenerationseinlass des Trocknungsrotors zugeführt wird. Durch die Umspülung des ersten Gebläses erwärmt sich diese Luft bereits. Eine weitere Erwärmung kann durch eine am Eingang des Regenerationseinlasses angeordnete Heizeinrichtung erfolgen.The air supplied via the housing inlet air is passed directly through the drying rotor without the use of the second blower and fed directly from this to the first fan, from which the air can be passed in compressed form into the soil layer to be dried. The regeneration of the rotor takes place by means of passage of room air, which is supplied via a second fan whose air flow is supplied via the housing of the first fan and from there to the first regeneration inlet of the drying rotor. By flushing the first blower, this air is already heated. Another Heating may occur through a heater located at the entrance of the regeneration inlet.

Die erfindungsgemäße Ausbildung der Trocknungsvorrichtung vermeidet eine Temperaturerhöhung der Prozessluft und hält damit die Temperatur der Trocknungsluft in sicheren Grenzen. Andererseits wird die notwendige Erwärmung der Regenerationsluft durch Vorbeileiten am Gehäuse des ersten Lüfters erreicht. Die zur weiteren Erhöhung der Temperatur der durch den Regenerationskanal geführten Spülluft mittels einer Heizeinrichtung lässt sich vorzugsweise in Abhängigkeit von der Temperatur des in die Heizeinrichtung eintretenden Luftstroms regeln. Damit lässt sich der Regenerationskanal des Trocknungsrotors unabhängig von äußeren Temperaturen im optimalen Bereich fahren.The inventive design of the drying device avoids a temperature increase of the process air and thus keeps the temperature of the drying air within safe limits. On the other hand, the necessary heating of the regeneration air is achieved by passing on the housing of the first fan. The rinsing air guided through the regeneration channel for further increasing the temperature by means of a heating device can preferably be regulated as a function of the temperature of the air stream entering the heating device. Thus, the regeneration channel of the drying rotor can be driven independently of external temperatures in the optimum range.

Zur Vereinfachung des Gehäuseaufbaus des Trocknungsgerätes kann der mit dem zweiten Gebläse verbundene Einlass für Raumluft an einem Abzweig des Ansaugstutzens angeschlossen sein, so dass lediglich ein einziger Ansaugstutzen im Trocknungsgerät erforderlich ist.To simplify the housing construction of the drying device, the inlet connected to the second fan inlet for room air may be connected to a branch of the intake manifold, so that only a single intake manifold in the drying device is required.

Vorzugsweise ist das Hochdruckgebläse als Seitenkanalverdichter ausgeführt, der einen hohen Druck ermöglicht, welcher bei Überführung von Trockenluft in Bodenschichten, wie z. B. unter einem Estrich, erforderlich ist.Preferably, the high pressure fan is designed as a side channel compressor, which allows a high pressure, which in the transfer of dry air in soil layers, such. B. under a screed is required.

Vorzugsweise ist das Trocknungsgerät in eine erste und eine zweite Kammer unterteilt, wobei der Trocknungsrotor einen Teil der Trennwand zwischen erster und zweiter Kammer bildet. Der ersten Kammer wird über einen Ansaugstutzen Raumluft zugeführt, die über den Trocknungsrotor zum ersten Gebläse geführt wird, welches sich in der zweiten Kammer befindet. Die Druckseite des ersten Gebläses ist an den Auslassstutzen angeschlossen.Preferably, the drying device is divided into a first and a second chamber, wherein the drying rotor forms part of the partition between the first and second chamber. The first chamber is supplied via an intake manifold room air, which is passed over the drying rotor to the first fan, which is located in the second chamber. The pressure side of the first blower is connected to the outlet.

Wenn das zweite Gebläse einen eigenen Ansaugstutzen aufweist, wird damit die gesamte in die erste Kammer eintretende Raumluft durch den Trocknungsrotor geführt. Durch die zweite Kammer wird ausschließlich die durch den zweiten Lüfter geführte Luft gespült, so dass die gesamte Abwärme des ersten Lüfters von dem Luftstrom des zweiten Lüfters aufgenommen wird und zur Spülung des Trocknungsrotors verwendet werden kann.If the second blower has its own intake manifold, so that all the air entering the first chamber room air is passed through the drying rotor. Through the second chamber, only the guided through the second fan air is rinsed, so that the total heat loss of the first fan of the Air flow of the second fan is recorded and can be used to flush the drying rotor.

Vorzugsweise ist der Trocknungsrotor wahlweise mit der Saugseite oder der Druckseite des ersten Gebläses verbindbar. Damit lässt sich das Trocknungsgerät sowohl im Saugverfahren als auch im Druckverfahren betreiben.Preferably, the drying rotor is selectively connectable to the suction side or the pressure side of the first blower. Thus, the drying device can be operated both in the suction process as well as in the printing process.

Wenn der Trocknungsrotor mit der Druckseite des ersten Gebläses verbunden ist, wird die Saugseite des ersten Gebläses an einen Raumluftanschluss des Trocknungsgerätes angeschlossen. Bei diesem Saugverfahren wird die vom ersten Lüfter verdichtete Raumluft durch den Trocknungsrotor hindurchgeführt und über die erste Kammer des Trocknungsgerätes an einen zu trocknenden Raum oder eine Bodenschicht abgegeben. Wenn der Ansaugstutzen des ersten Gebläses direkt an die Bodenschicht angeschlossen ist, führt der Auslass der ersten Kammer getrocknete Luft in den Raum zurück, so dass sich ein Trocknungskreislauf ergibt.When the drying rotor is connected to the pressure side of the first blower, the suction side of the first blower is connected to a room air connection of the drying device. In this suction method, the compressed air from the first fan room air is passed through the drying rotor and discharged through the first chamber of the drying device to a room to be dried or a bottom layer. When the inlet port of the first blower is directly connected to the soil layer, the outlet of the first chamber returns dried air into the space, resulting in a drying cycle.

In dem Fall, dass der Trocknungsrotor mit der Saugseite des ersten Gebläses verbunden ist, wird die Druckseite des ersten Gebläses an einen Raumluftanschluss des Trocknungsgerätes angeschlossen. Der Raumluftanschluss kann dann an eine Bodenschicht des Raumes angeschlossen werden, so dass die Bodenschicht mittels Druckluft durchströmt wird. Der Raumluftanschluss der oberen Kammer nimmt die aus der Bodenschicht austretende Raumluft auf und trocknet sie.In the case that the drying rotor is connected to the suction side of the first blower, the pressure side of the first blower is connected to a room air connection of the drying device. The room air connection can then be connected to a bottom layer of the room, so that the bottom layer is flowed through by compressed air. The room air connection of the upper chamber absorbs the air escaping from the floor layer and dries it.

Die wahlweise Verwendung des Trocknungsrotors lässt sich sehr einfach dadurch umschalten, dass entsprechende wechselbare Schlauchverbindungen verwendet werden. In einer alternativen Ausführungsform kann die wahlweise Verbindung auch über ein Dreiwegeventil herstellbar sein.The optional use of the drying rotor can be switched easily by using corresponding replaceable hose connections. In an alternative embodiment, the optional connection can also be produced via a three-way valve.

In einer weiteren bevorzugten Ausführungsform verzichtet das Trocknungsgerät auf einen eigenständigen Antrieb für den zweiten Lüfter. Bei dieser Ausführungsform wird der zweite Lüfter vom Motor des ersten Lüfters mit angetrieben. Dadurch ergibt sich ein vereinfachter Gehäuseaufbau.In a further preferred embodiment, the drying device dispenses with an independent drive for the second fan. In this embodiment, the second fan is driven by the motor of the first fan. This results in a simplified housing structure.

Die in Fig. 1 dargestellte Prinzipansicht eines Trocknungsgerätes zeigt einen Trocknungsrotor 3, dem über einen Ansaugstutzen 1 Raumluft zugeführt wird, die vom Trocknungsrotor 3 über ein erstes Gebläse 4 an einen Auslassstutzen 2 geführt wird, von dem die getrocknete Raumluft in den zu entfeuchtenden Bereich überführt wird. Ein zweites Gebläse 5 saugt über einen Einlass 6 ebenfalls Raumluft an, welche über das Gehäuse 7 des ersten Lüfters geführt wird und von dort über eine Heizeinrichtung 10 dem Regenerationseinlass 8 des Trocknungsrotors und von dort über einen Gehäuseauslass 9 an eine äußere Atmosphäre abgegeben wird.The illustrated in Fig. 1 principle view of a drying apparatus shows a drying rotor 3, which is supplied via an intake 1 room air, which is guided by the drying rotor 3 via a first fan 4 to an outlet 2, from which the dried room air transferred to the area to be dehumidified becomes. A second blower 5 also sucks in room air via an inlet 6, which is conducted via the housing 7 of the first fan and from there via a heating device 10 to the regeneration inlet 8 of the drying rotor and from there via a housing outlet 9 to an external atmosphere.

Die in den Ansaugstutzen 1 eintretende Luft wird mittels des Trocknungsrotors 3 getrocknet und über das erste Gebläse verdichtet an die zu entfeuchtende Schicht abgegeben. Die im Trocknungsrotor 3 aufgenommene Feuchte wird durch Rückspülung ständig entfernt, so dass das Trocknungsgerät im Dauerbetrieb arbeiten kann.The entering into the intake 1 air is dried by means of the drying rotor 3 and discharged via the first blower compressed to the layer to be dehumidified. The moisture absorbed in the drying rotor 3 is constantly removed by backwashing so that the drying device can operate in continuous operation.

Bei einem Trocknungsrotor der verwendeten Art handelt es sich um ein an sich bekanntes radförmiges Trocknungselement mit einer wabenförmigen Struktur mit sehr großer Oberfläche. Die vom Rotor aufgenommene Feuchtigkeit wird abgegeben, sobald der Trocknungsrotor im Regenerationsbereich von heißer Luft im Gegenstrom durchspült wird. Der Rotor dreht mit einer Geschwindigkeit von etwa 0,5 Umdrehungen pro Minute, angetriebenen durch einen langsam drehenden Motor. Adsorptionstrockner der genannten Art sind als solche bekannt.A drying rotor of the type used is a per se known wheel-shaped drying element having a honeycomb structure with a very large surface area. The moisture absorbed by the rotor becomes discharged as soon as the drying rotor is rinsed in the regeneration region of hot air in countercurrent. The rotor rotates at a speed of about 0.5 revolutions per minute driven by a slowly rotating motor. Adsorption of the type mentioned are known as such.

Fig. 2 zeigt den mechanischen Aufbau eines quaderförmigen Trocknungsgerätes der beanspruchten Art. Das Trocknungsgerät weist im Wesentlichen eine obere erste Kammer 11 und eine untere zweite Kammer 12 auf, wobei der Trocknungsrotor 3 einen Teil der Trennwand 13 zwischen der ersten Kammer 11 und der zweiten Kammer 12 bildet. Die Kammer 11 ist mit einem Ansaugstutzen 1 sowie einem Einlass 6 versehen. An den Einlass 6 ist ein zweiter Lüfter 5 angeschlossen, dessen Auslass 14 in die zweite Kammer 12 mündet.Fig. 2 shows the mechanical structure of a cuboid drying apparatus of the claimed type. The drying apparatus has substantially an upper first chamber 11 and a lower second chamber 12, wherein the drying rotor 3 is a part of the partition wall 13 between the first chamber 11 and the second chamber 12 forms. The chamber 11 is provided with an intake 1 and an inlet 6. To the inlet 6, a second fan 5 is connected, the outlet 14 opens into the second chamber 12.

Die über den Ansaugstutzen 1 in die erste Kammer 11 eintretende Raumluft wird über den in der zweiten Kammer 12 angeordneten Seitenkanalverdichter, der das erste Gebläse 4 bildet, angesaugt, indem die durch den Trocknungsrotor 3 geführte Raumluft über eine Schlauchverbindung 16 unmittelbar in das erste Gebläse 4 eingesaugt wird. Die im ersten Gebläse 4 verdichtete Luft wird über einen Auslassstutzen 2 aus dem Trocknungsgerät ausgegeben.The entering via the intake 1 in the first chamber 11 room air is sucked in via the arranged in the second chamber 12 side channel compressor, which forms the first fan 4, by the guided through the drying rotor 3 room air via a hose connection 16 directly into the first fan. 4 is sucked in. The compressed in the first fan 4 air is discharged through an outlet 2 from the drying device.

Die durch das zweite Gebläse 5 in die zweite Kammer 12 eingeblasene Raumluft umstreicht das Gehäuse des ersten Gebläses 4 und wird dann über die Heizeinrichtung 10 und den Gehäuseauslass 9 in die Rückspülstrecke des Trocknungsrotors 3 und von dort über einen Gehäuseauslass 9 an die Außenatmosphäre geleitet. Um in der Heizeinrichtung 10 die nötige Wärme erzeugen zu lassen, wird die Luftraumtemperatur in der zweiten Kammer 12 durch einen nicht dargestellten Sensor erfasst. Das Sensorsignal steuert über eine geeignete Steuereinrichtung die Heizleistung der Heizeinrichtung 10, so dass die über den Regenerationseinlass 8 in den Trocknungsrotor eintretende Sprühluft eine optimale Arbeitstemperatur aufweist.The blown through the second fan 5 in the second chamber 12 room air surrounds the housing of the first blower 4 and is then passed through the heater 10 and the housing outlet 9 in the backwash of the drying rotor 3 and from there via a housing outlet 9 to the outside atmosphere. In order to generate the necessary heat in the heater 10, the air space temperature in the second chamber 12 is detected by a sensor, not shown. The sensor signal controls the heating power of the heating device 10 via a suitable control device, so that the spray air entering the drying rotor via the regeneration inlet 8 has an optimum operating temperature.

Fig. 3 zeigt ein Trocknungsgerät der erfindungsgemäßen Art bei Verwendung im Saugverfahren. Hierbei wird über den Raumluftanschluss 15 Raumluft über das erste Gebläse 4 angesaugt und über den Trocknungsrotor 3 an den Raumluftanschluss 17 abgegeben. Über den Einlass 6 wird Raumluft mittels des zweiten Gebläses 5 über das Gehäuse 7 des ersten Gebläses 4 geführt und über die Heizeinrichtung 10 dem Regenerationseinlass des Trocknungsrotors 3 zugeführt, von dem die Spülluft über den Gehäuseauslass 9 an die Atmosphäre abgegeben wird.Fig. 3 shows a drying device of the type according to the invention when used in the suction process. Here, room air is sucked in via the room air connection 15 via the first blower 4 and via the drying rotor 3 to the room air connection 17 issued. Room air is guided via the inlet 6 via the housing 7 of the first blower 4 by means of the second blower 5 and fed via the heating device 10 to the regeneration inlet of the drying rotor 3, from which the purging air is discharged via the housing outlet 9 to the atmosphere.

Der mechanische Aufbau des in Fig. 3 dargestellten Saugprinzips ist in Fig. 4 dargestellt. Vom Raumluftanschluss 15 wird Raumluft vom ersten Gebläse 4 angesaugt und über den Druckluftanschluss über die Schlauchverbindung 16, die teilweise außerhalb des Gehäuses geführt ist, an den Trocknungsrotor 3 gegeben, von dem die darin getrocknete Luft über den Raumluftanschluss 17 aus dem Trocknungsgerät abgegeben wird. Auch in diesem Fall erfolgt die Rückspülung des Trocknungsrotors 3 über vom zweiten Gebläse 5 durch die zweite Kammer 12 geführte Raumluft, die über die Heizeinrichtung 10 durch die Rückspülstrecke des Trocknungsrotors geführt wird und über den Gehäuseauslass 9 an die äußere Atmosphäre abgegeben wird.The mechanical structure of the suction principle shown in Fig. 3 is shown in Fig. 4. From the room air connection 15, room air is sucked in by the first blower 4 and supplied via the compressed air connection via the hose connection 16, which is partially guided outside the housing, to the drying rotor 3, from which the air dried therein is discharged via the room air connection 17 from the drying device. Also in this case, the backwashing of the drying rotor 3 via the second fan 5 through the second chamber 12 guided room air, which is passed through the heater 10 through the backwash of the drying rotor and is discharged through the housing outlet 9 to the outside atmosphere.

Die alternative Verwendung des Trocknungsgerätes im Saugverfahren oder Druckverfahren lässt sich daher durch einfachen Wechsel der Schlauchverbindung 16 herstellen, indem ein Ende des außerhalb des Gerätes geführten Schlauches alternativ an den Raumluftanschluss 15 (Fig. 2) oder den Auslassstutzen 2 (Fig. 4) angeschlossen wird.The alternative use of the drying device in the suction method or printing method can therefore be produced by simply changing the hose connection 16 by connecting one end of the hose led outside the device alternatively to the room air connection 15 (FIG. 2) or the outlet connection 2 (FIG. 4) ,

In einer anderen Ausführungsform der Erfindung, die in Fig. 5 dargestellt ist, lässt sich das Wechseln der Anschlüsse auch durch Verwendung eines drehbaren Dreiwegeventils 18 erreichen, so dass eine vereinfachte Bedienung des Gerätes zur wahlweisen Verwendung im Druck- oder Saugbetrieb erreichbar ist.In another embodiment of the invention shown in Fig. 5, changing the ports can also be achieved by use of a rotary three-way valve 18, so that a simplified operation of the device for selective use in the printing or suction operation can be achieved.

Fig. 5 zeigt auch eine Möglichkeit der Verwendung des zweiten Gebläses 5, bei der das Gebläse 5 unmittelbar vom Motor des ersten Gebläses 4 angetrieben wird. Durch den Antrieb des ersten Gebläses 4 wird damit gleichzeitig das zweite Gebläse 5 betrieben, welches über einen rückseitigen Einlass Raumluft in die zweite Kammer 12 einführt.Fig. 5 also shows a possibility of using the second blower 5, in which the blower 5 is driven directly by the motor of the first blower 4. By the drive of the first fan 4 so that the second fan 5 is simultaneously operated, which introduces room air into the second chamber 12 via a rear inlet.

Das dargestellte Trocknungsgerät ist kompakt aufzubauen und einfach herstellbar. Die Verbindung der zentralen Elemente des Gerätes, nämlich Trocknungsrotor, erste und zweite Lüfter und die Anschlüsse nach außen lassen sich sehr einfach durch flexible Schlauchverbindungen herstellen, wobei aber auch metallische Rohrverbindungen verwendbar sind. Zur Geräuschverringerung kann das Gehäuse mit geräuschdämmenden Auskleidungen versehen sein.The drying device shown is compact and easy to manufacture. The connection of the central elements of the device, namely drying rotor, first and second fan and the connections to the outside can be very easily produced by flexible hose connections, but also metallic pipe connections are used. To reduce noise, the housing may be provided with sound-absorbing linings.
