Description
LufttrocknungseinrichtungAir drying device
Stand der Technik Die Erfindung geht aus von einer Lufttrocknungseinrichtung nach der Gattung des Hauptanspruchs. Eine derartige Einrichtung ist bekannt.PRIOR ART The invention is based on an air drying device according to the genre of the main claim. Such a device is known.
Bei dieser bekannten Einrichtung sorgt ein Maximal-Minimal-Druckschalter dafür, daß beim Erreichen eines Maximal-Behälterciruckes der Kompressor auf Leerlauf geschaltet wird und ein Teil der im Behälter gespeicherten Druckluft den Trockner rückwärts durchfließt, um dessen Trokkgnmediumzu regenerieren. Der Druckschalter übernimmt dabei die gesamte Schaltarbeit, was leicht zu Störungen Anlaß gibt. Außerdem hat die bekannte Einrichtung auch ein langsames Ansprechverhalten. Sie muß deshalb als Schnappschalter ausgebildet werden und ist entsprechend kompliziert.In this known device, a maximum-minimum pressure switch provides ensure that the compressor idles when a maximum tank jerk is reached is switched and part of the compressed air stored in the container causes the dryer flows backwards to regenerate its dry medium. The pressure switch takes over the entire switching work, which can easily lead to malfunctions. aside from that the known device also has a slow response. She must therefore be designed as snap switches and is correspondingly complicated.
Vorteile der Erfindung Die Lufttrocknungseinrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber die Vorteile, daß für die Schaltarbeit zwei Mehrwegeventile verwendet werden, die für eine exakte Schaltung besonders geeeignet sind. Dazu kommt, daß die in Serienfertigung herstellbaren Mehrwegeventile schwer zulässig sind. Schließlich ist es auch ein Vorteil der Einrichtung, daß sie leicht verschiedenen Einbaubedingungen und -erfordernissen angepaßt werden kann.Advantages of the invention The air drying device with the characterizing Features of the main claim has the advantages that for switching work two multi-way valves are used, which are particularly suitable for precise switching are. In addition, the multi-way valves that can be mass-produced are difficult are permitted. Finally, it is also an advantage of the device that it is lightweight can be adapted to various installation conditions and requirements.
Weitere Vorteile der Erfindung ergeben sich aus der Beschreibung und aus den Unterans-prüchen.Further advantages of the invention emerge from the description and from the sub-claims.
Zeichnung Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert.Drawing An embodiment of the invention is shown in the drawing and explained in more detail in the following description.
Beschreibung des Ausführungsbeispieles Ein Kompressor 1 ist über eine Leitung 2 an einen Druckregler 3 angeschlossen. Dieser Druckregler 3 ist mit lKerse einem Schaltanschluß für eine Leitung 30 er gewöhnlich drucklos, bei Leerlaufstellung des Druckreglers 3 aber unter Druck steht. Hinter dem Druckregler 3 ist eine Lufttrocknungseinrichtung 5 angeordnet, die einen mit regenerierbarem Trocknungsmaterial gefüllten Lufttrockner 6, zwei Mehrwegeventile 7 und 8, ein Rückschlagventil 9 und eine Drossel 10 aufweist. Die beiden Mehrwegeventile 7 und 8 bilden eine Ventileinrichtung 7/8 und sie sind beide an die Leitung 30 angeschlossen, um von dem jeweiligen Druck in dieser Leitung 30 betätigt zu werden. Dabei ist dem Mehrwegeventil 7 ein Drossel-Rückschlagventil 29 vorgeschaltet.Description of the exemplary embodiment A compressor 1 is via a Line 2 connected to a pressure regulator 3. This pressure regulator 3 is with lKerse a switching connection for a line 30 he usually depressurized, in the idle position of the pressure regulator 3 is under pressure. Behind the pressure regulator 3 is an air drying device 5 arranged, which is a filled with regenerable drying material air dryer 6, two multi-way valves 7 and 8, a check valve 9 and a throttle 10. The two multi-way valves 7 and 8 form a valve device 7/8 and they are both connected to the line 30 in order to be aware of the respective pressure in this line 30 to be operated. The multi-way valve 7 is a one-way flow control valve 29 upstream.
Mit der Lufttrocknungseinrichtung 5 ist eine Druckdose 21 kombiniert. Diese Druckdose 21 hat eine Membran 22, die als Schließ- oder Drosselglied einer Rohrausmündung.23 arbeitet. Die Membran 22 und die Rohrausmündung 23 bilden eine Ventileinrichtung 22/23. Die Rohrausmündung 23 ist in einer Kammer 24 angeordnet, die einen von einer Leitung 26 hinter dem Rückschlagventil 9 abgezweigten Regenierungsluftstrom über die feste Drossel 10 an den Lufttrockner 6 abgibt. Von der gleichen Stelle 27 hinter dem Rückschlagventil 9 nimmt eine Rückmeldeleitung 25 ihren Ausgang, die zum Druckregler 3 zurückführt, um diesem den Behälterdruck zu melden. Eine zweite Kammer 28 der Druckdose 21 ist über das 2/2-Wege-Ventil 8 an den Vorratsbehälter 13 ans#chließbar.A pressure cell 21 is combined with the air drying device 5. This pressure cell 21 has a membrane 22 as a closing or throttle member of a Orifice. 23 works. The membrane 22 and the pipe mouth 23 form one Valve device 22/23. The pipe mouth 23 is arranged in a chamber 24, the one branched off from a line 26 behind the check valve 9 regeneration air flow delivers to the air dryer 6 via the fixed throttle 10. From the same place 27 behind the check valve 9, a feedback line 25 takes its output, the to the pressure regulator 3 in order to report the tank pressure to it. A second Chamber 28 of the pressure cell 21 is connected to the storage container via the 2/2-way valve 8 13 connectable.
Die Einrichtung arbeitet auf folgende Weise: Beim Auffüllen des Vorratsbehälter 13 stehen die beiden Ventile 7 und 8 der Ventileinrichtung 7/8 in der gezeichneten Stellung. Wenn der Druckregler 3 umschaltet, gelangt über die Leitung 30 die Ventileinrichtung 7/8 unter Druck. Die Ventile 7 und 8 schalten um, und zwar das Ventil 8 sofort und das Ventil 7 - über das Drosselrückschlagventil 29 - verzögert. In der Kammer 28 wird der maximale Vorratsdruck eingeschlossen, und die Regenerationsluft kann so lange über die Kammer 24 strömen, bis der in der Kammer 24 wirkende Behälterdruck so weit abgesunken ist, daß der Differenzdruck das Anlegen der Membran 22 an der Rohrausmündung 23 bewirkt. Dann ist die Regeneration beendet.The device works in the following way: When the reservoir is refilled 13 are the two valves 7 and 8 of the valve device 7/8 in the drawn Position. When the pressure regulator 3 switches over, the valve device arrives via the line 30 7/8 under pressure. The valves 7 and 8 switch over, namely the valve 8 immediately and the valve 7 - via the one-way flow control valve 29 - is delayed. In chamber 28 the maximum supply pressure is included, and the regeneration air can so long flow through the chamber 24 until the container pressure acting in the chamber 24 has dropped so far that the differential pressure is the application of the membrane 22 to the Pipe opening 23 causes. Then the regeneration is over.
Wenn dann der Druckregler 3 wieder in die Förderphase umschaltet, wird die Leitung 30 entlüftet und die Ventileinrichtung 7/8 geht in ihre Ausgangsstellung zurück.When the pressure regulator 3 switches back to the delivery phase, the line 30 is vented and the valve device 7/8 goes into its starting position return.
