Description

In der- Industrie, z. B. im Papierverarbeitungsgewerbe zum Anlegen und Abnehmen der Bogen, braucht man vielfach gleichzeitig Saug- und Blasluft. Es ist bekannt, mit einem Drehkolbengebläse sowohl einen Saug- wie auch einen B.lasstrom zu erzeugen und außerdem auf der Vakuumseite zur Kühlung der Maschine Frischluft zuzusetzen und den Blasstrom anzureichern.In the industry, e.g. B. in the paper processing industry to create and removing the sheet, you often need suction and blowing air at the same time. It is known to have both a suction and a B.lasstrom with a rotary piston blower to generate and also fresh air on the vacuum side to cool the machine add and enrich the blow stream.

Das Problem, welches die Erfindung löst, ergibt sich daraus, daß es ein Gebot der Wirtschaftlichkeit ist, die Leistungen eines Gebläses den verschiedenartigen und oft wechselnden Ansprüchen anpassen zu können. Die Erfindung betrifft daher ein Drehkolbengebläse mit Schieberkolben und mehreren Förderstufen, bei dem mehrere am Zylinderumfang verteilte Anschlüsse für das Fördermittel vorgesehen sind, und besteht darin, daß die Sauganschlüsse miteinander und/oder die Druckanschlüsse miteinander durch verstellbare Ventile verbunden sind. Außerdem kann einer der Sauganschlüsse, der an der Umfangstelle größten Zelleninhalts sich befindet, mit der Außenluft verbunden sein.The problem which the invention solves arises from the fact that it A requirement of economy is that the performance of a blower is different and to be able to adapt to changing requirements. The invention therefore relates to a rotary piston blower with slide piston and several delivery stages, in which several on the circumference of the cylinder distributed connections are provided for the conveying means, and consists in that the suction connections with each other and / or the pressure connections with each other are connected by adjustable valves. In addition, one of the suction connections, which is located at the circumference of the largest cell content, connected to the outside air be.

In der Zeichnung ist ein Ausführungsbeispiel im Schnitt dargestellt.An exemplary embodiment is shown in section in the drawing.

In dem Gebläsegehäuse n dreht sich der Schieberkolben na entgegen dem Uhrzeigersinn, so daß sich in der linken Hälfte vom Nullpunkt o bis -zum Zenith z Vakuum und rechts Kompression ergibt. Die beiden Anschlüsse A und B können, da sie zunächst voneinander getrennt sind, mit ihren Saugströmen unabhängig. voneinander an verschiedenen Stellen wirksam werden. Wird an einer Arbeitsstelle A ein besonders kräftiger Saugstrom gebraucht, so kann das Ventil h geöffnet werden, und das Vakuum B verstärkt A. Genügt jedoch der Saugstrom A dem Bedarf und Vakuum B wird nicht benötigt, dagegen ein kräftiger Blasstrom C, so wird das Ventil k geschlossen -und Ventil i geöffnet, so daß Frischluft .die Schi.eberzelle im Zenith z füllt.In the fan housing n, the slide piston na rotates counterclockwise, so that in the left half from zero point o to - to the zenith z there is vacuum and on the right there is compression. The two connections A and B can, since they are initially separated from each other, with their suction flows independently. take effect from each other in different places. If a particularly strong suction flow is required at work A, valve h can be opened and vacuum B increases A. If, however, suction flow A meets the demand and vacuum B is not required, but a strong blowing flow C, the valve becomes k closed and valve i opened, so that fresh air fills the slider cell at the zenith z.

Auf der Kompressionsseite können die Anschlüsse C und D voneinander getrennt sein und mit verschiedenen Drücken arbeiten, z. B. C mit einem kräftigen Blasstrom niedern Druckes zum Ablegen der Bogen einer Papierverarbeitungsmaschine, während im Anschluß D geringere Mengen hochgespannter Druckluft zur Verfügung stehen, beispielsweise zur Betätigung einer Druckbestäubervorrichtung. Steht im Anschluß D zuviel Hochdruckluft zur Verfügung, so strömt der Überfluß durch das überströmventil p in den Raum.C und verstärkt dessen Blasstrom. Wird das Ventil e geschlossen, so kommt der Strom D ganz dem Blasstrom C zugute.On the compression side, ports C and D can be separated from one another and work with different pressures, e.g. B. C with a powerful blow stream of low pressure to deposit the sheets of a paper processing machine, while in connection D smaller amounts of high-pressure compressed air are available, for example to operate a pressure sprayer. If too much high-pressure air is available in connection D, the excess flows through the overflow valve p into room C and increases its blowing flow. If the valve e is closed, the flow D is used entirely for the blowing flow C.

Das erfindungsgemäße Drehkolbengebläse bietet somit den Vorteil, daß durch das einfache Verstellen von Ventilen sowohl die Saug- wie die Blasleistung innerhalb der Höchstgrenzen variiert und dadurch aus der Maschinenanlage insgesamt eine Höchstleistung herausgeholt werden kann. Außerdem bringt die Erfindung den Fortschritt, daß die Maschinenleistung den ständig wechselnden, verschiedenartigen Bedürfnissen individuell angepaßt werden kann, wie sie z. B. die verschieden schweren Papiersorten und Bogengrößen, sei es in bezug auf Saugluft oder Blasluft, stellen.The rotary piston blower according to the invention thus offers the advantage that through the simple adjustment of valves, both the suction and the blowing power varies within the maximum limits and therefore from the machine system as a whole maximum performance can be achieved. In addition, the invention brings the Progress that machine performance is constantly changing, diverse Needs can be customized, such as. B. the different levels of difficulty Paper types and sheet sizes, be it with regard to suction air or blown air.
