Abstract

An evacuating pump set, in particular for milking equipment, has a modular unit comprising an evacuating pump (2) and a drive motor (3), which can be inserted in a service water tank (4) to utilise the waste heat. The modular unit (1) is mounted on a cover plate (5) associated with a connecting flange (6) of the tank (4), and pipelines (7, 8) passing through the cover plate (5) to the pump (2) inside form the pump intake and discharge lines. In order to be able to improve the utilisation of waste heat substantially in a simple manner, two coaxial pipelines (7, 8) are provided, of which the outer pipeline (7) acts as the discharge line and the inner pipeline (8) as the intake line for the pump (2). <IMAGE>

Description

Die Erfindung bezieht sich auf ein Vakuumpumpen­ aggregat, insbesondere für Melkanlagen, mit einer aus Vakuumpumpe und Antriebsmotor bestehenden Baueinheit, die zur Abwärmenutzung in einen Brauchwasserbehälter od. dgl. einsetzbar ist, wobei eine einem Anschluß­ flansch des Behälters zugeordnete Deckelplatte die Baueinheit aufnimmt und durch die Deckelplatte zur innenliegenden Pumpe führende Rohrstränge die Pumpen­ saug- und -druckleitung bilden.The invention relates to a vacuum pump aggregate, especially for milking systems, with one Vacuum pump and drive motor existing unit, the for waste heat use in a domestic water tank od. Like. Can be used, one connection flange of the container associated cover plate Unit takes up and through the cover plate internal pumps leading pipe strands the pumps Form suction and pressure line.

Vakuumpumpenaggregate werden für die ver­ schiedensten Zwecke gebraucht, beispielsweise zum Betreiben von Melkanlagen, bei denen die Melkbecher und das ganze Milchleitungs- und -schleusensystem unter Unterdruck stehen und oft auch die Milchpumpe für die Milschwäsche und -abfüllung durch entsprechende Unter­ druckbeaufschlagung läuft. Um die beim Einsatz des Pumpenaggregates anfallende beträchtliche Verdichtungs­ wärme und andere Abwärme zu nutzen, ist es bereits be­ kannt, die aus Pumpe und Motor bestehende Baueinheit was­ serdicht abzukapseln und in einen Brauchwasser­ behälter einzusetzen und mit dieser Abwärme Warm­ wasser zu bereiten. Allerdings ist bisher die Wirt­ schaftlichkeit dieser Abwärmenutzung gering, da die im Wasserbehälter verlaufende kalte Pumpensaugleitung eine Rückkühlung des Brauchwassers bewirkt und es insgesamt daher zu keinem für eine Brauchwasserbereitung ausreichenden Heizeffekt kommt.Vacuum pump units are used for the ver various purposes, for example Operating milking systems where the milking cup and the whole milk line and lock system below Are under pressure and often the breast pump for the Milk washing and filling by appropriate sub pressurization is running. To ensure that when using the Pump unit considerable compression to use heat and other waste heat, it is already knows what the unit consisting of pump and motor encapsulate in a water-tight manner and into a service water insert container and warm with this waste heat to prepare water. So far, however, has been the host  Economical use of waste heat is low because the Cold pump suction line running in the water tank causes the process water to be recooled and it altogether therefore none for a domestic water preparation sufficient heating effect comes.

Der Erfindung liegt daher die Aufgabe zugrunde, diese Mängel zu beseitigen und ein Vakuumpumpen­ aggregat der eingangs geschilderten Art zu schaffen, das sich bei einfacher, raumsparender Konstruktion vor allem durch seine Möglichkeit einer überaus rationellen Abwärmenutzung auszeichnet.The invention is therefore based on the object to eliminate these shortcomings and a vacuum pump to create an aggregate of the type described at the outset, that comes with a simple, space-saving design all thanks to its possibility of being extremely rational Waste heat use distinguished.

Die Erfindung löst diese Aufgabe dadurch, daß zwei ineinander verlaufende Rohrstränge vorgesehen sind, von denen der äußere Rohrstrang als Drucklei­ tung und der innere Rohrstrang als Saugleitung für die Pumpe dienen. Durch die innerhalb der Druckleitung liegende Saugleitung wird das niedertemperierte, von der Pumpe angesaugte Medium gegenüber dem Brauchwasser abgeschirmt und kann keine Rückkühlung des Brauch­ wassers verursachen. Außerdem bringt der Verlauf der Saugleitung innerhalb der wärmeren Druckleitung eine Vorwärmung des angesaugten Mediums mit sich, so daß durch die Verdichtungswärme ein höheres Tempera­ turniveau beim von der Pumpe ausgestoßenen Medium er­ zielt und dadurch auch ein höherer Heizeffekt er­ reicht wird. Die einfache Maßnahme, Druck- und Saug­ leitung ineinander zu führen, gewährleistet demnach einen besonders hohen Abwärmenutzungsgrad, ver­ ringert die Dichtungsschwierigkeiten beim Durchführen der Druck- und Saugleitungen durch die Deckelplatte und erlaubt eine kompakte, platzsparende Bauweise.The invention solves this problem in that two intertwining pipe strings are provided are, of which the outer pipe string as Drucklei tion and the inner pipe string as a suction line for serve the pump. By inside the pressure line lying suction line becomes the low-temperature, from medium sucked in by the pump compared to the domestic water shielded and can not recool the custom cause water. In addition, the course of the Suction line inside the warmer pressure line a preheating of the aspirated medium with it, so that by the heat of compression a higher tempera level of the medium ejected by the pump targets and thereby a higher heating effect is enough. The simple measure, pressure and suction guiding cables into one another therefore guarantees a particularly high degree of waste heat utilization, ver alleviates the sealing difficulties when performing the pressure and suction lines through the cover plate and allows a compact, space-saving design.

In der Zeichnung ist ein erfindungsgemäßes Vakuumpumpenaggregat anhand eines Schemabildes ver­ anschaulicht. In the drawing is an inventive Vacuum pump unit using a schematic image ver vividly.  

Um die Abwärme eines Vakuumpumpenaggregates wirt­ schaftlich nutzen zu können, wird die Baueinheit 1 aus Vakuumpumpe 2 und elektrischem Antriebsmotor 3 in einem Brauchwasserbehälter 4 eingesetzt. Dazu trägt die Bau­ einheit 1 eine Deckelplatte 5, mit der sie, ins Behälter­ innere vorkragend, an einem Anschlußflansch 6 des Be­ hälters 4 montierbar ist. Die von der innenliegenden Vakuumpumpe 2 zur Deckelplatte 5 führenden Pumpen­ leitungen bilden zwei ineinander verlaufende Rohr­ stränge 7, 8, wobei, um Rückkühlungen des Brauch­ wassers zu verhindern, der äußere Rohrstrang 7 als heißere Druckleitung und der innere Rohrstrang 8 als kühlere Saugleitung der Pumpe 2 dienen.In order to be able to use the waste heat from a vacuum pump unit economically, the assembly 1 comprising the vacuum pump 2 and the electric drive motor 3 is used in a service water tank 4 . For this purpose, the construction unit 1 carries a cover plate 5 with which it, projecting into the inner container, can be mounted on a connecting flange 6 of the container 4 . The leading from the internal vacuum pump 2 to the cover plate 5 pump lines form two interlocking pipe strands 7, 8 , whereby, in order to prevent recooling of the domestic water, the outer pipe string 7 as the hotter pressure pipe and the inner pipe string 8 as the cooler suction pipe of the pump 2 serve.

Durch die erfindungsgemäße Konstruktion er­ gibt sich auf einfache und platzsparende Weise die Möglichkeit einer wirkungsvollen Abwärmenutzung, da das Wasser des Brauchwasserbehälters 4 nur mit der Baueinheit 1 selbst und dem heißen Rohrstrang 7 der Pumpendruckleitung in Berührung kommt, nicht aber mit der innerhalb der Druckleitung liegenden kühlen Pumpensaugleitung.Due to the construction according to the invention he gives in a simple and space-saving way the possibility of effective waste heat use, since the water of the process water tank 4 only comes into contact with the assembly 1 itself and the hot tubing 7 of the pump pressure line, but not with the cooler located within the pressure line Pump suction line.
