Abstract

The piston pump is particularly intended for handling foodstuffs, such as milk, wine, beer etc. It comprises a stuffing box housing (4) provided with connections (10-12) through which cleaning fluid enters to flow around the seals (4a, b) and the piston rod (3) or plunger, after which it emerges through outlet ducts (10a, 11a, 12a). The piston (2) may be provided with ducts (9) through which cleaning liquid is introduced between the piston seals (2a, b). The cleaning liquid, fed to the housing, may be taken from the pump cylinder (1) or pump outlet (8).

Description

Kolbenpumpe für Nahrungsmittel Piston pump for food

Nahrungsmittel, wie Milch, Wein oder Bier werden allgemein mit Zentrifugal-, Kapsel- oder Membranpumpen gefördert, weil diese Pumpen die Möglichkeit der Reinigung am sichersten bieten.Food such as milk, wine or beer are generally treated with centrifugal, Capsule or diaphragm pumps are promoted because these pumps have the option of cleaning safest to offer.

Diese aufgezählten Pumpen haben verschiedene Nachteile. Mit einer Zentrifugalpumpe für Nahrungsmittel erreicht man z.B. nur einen begrenzten Druck, die Kapselpumpe ist infolge ihrer Paßgenauigkeit sehr verschleißanfällig, beide Pumpenarten lassen eine vorbestimmte Durchflußmenge, also z.B. eine Dosierung nicht zu. Eine Membranpumpe läßt sich gut reinigen, läßt eine vorbestimmte Durchflußmenge zu, aber sie erreicht wegen der Membranfestigkeit nur eine Förderhöhe von 5 bar.These enumerated pumps have several disadvantages. With a Centrifugal pumps for food, for example, only achieve a limited pressure, the capsule pump is very susceptible to wear due to its accuracy of fit, both Pump types do not allow a predetermined flow rate, e.g. dosing to. A membrane pump is easy to clean and allows a predetermined flow rate closed, but due to the strength of the membrane it only reaches a delivery head of 5 bar.

Es ist rufgabe dieser Erfindung, eine Kolbenpumpe für Nahrungsmittel zu schaffen, die einmal einen beliebig hohen Druck überwindet, zum anderen eine vorbestimmte Menge genau fördert und bei der erfindungsgemäß alle Innenflächen zu reinigen sind, was bisher bei Kolbenpumpen nur sehr schwer möglich gewesen sein dürfte.It is the object of this invention to provide a piston pump for food to create that on the one hand overcomes an arbitrarily high pressure, on the other hand one precisely promotes a predetermined amount and, according to the invention, all inner surfaces close cleaning are what was previously very difficult to do with piston pumps should.

Die Aufgabe der einwandfreien Reinigung der Kolbenpumpe für Nahrungsmittel wird dadurch gelöst, daß Reinigungsflüssigkeit das Stopfbuchsengehäuse und den Kolben durchspült.The task of properly cleaning the piston pump for food will solved in that cleaning liquid the gland housing and the piston flushed through.

Ausführungsbeispiele der Erfindung sind anhand der Figuren I und II erläutert.Embodiments of the invention are based on Figures I and II explained.

In Fig. I bewegt sich in bekannter Weise im Pumpenzylinder 1 der Pumpen kolben 2 über die Kolbenstange 3. In bekannter Weise tritt bei dieser doppelwirkenden Ausführung das zu fördernde Medium durch die Saugstutzen 5 und 6 ein, um den Pumpenzylinder 1 durch die Druckstutzen 7 und 8 zu verlassen.In Fig. I moves in a known manner in the pump cylinder 1 of the pumps piston 2 over the piston rod 3. In a known manner, this double-acting occurs Execute the medium to be conveyed through the suction nozzles 5 and 6 to the pump cylinder 1 through the pressure ports 7 and 8.

Erfindungsgemäß wird über die Stopfbuchsenreinigungskanäle 10, 11 und 12 Reinigungsflüssigkeit in das Stopfbuchsengehäuse geleitet, die z.B. dem Pumpenzylinder 1 oder den Druckstutzen 7 und 8 entnommen werden kann, oder auch fremd zuzuführen ist.According to the invention, the stuffing box cleaning channels 10, 11 and 12 cleaning liquid is fed into the gland housing, for example the pump cylinder 1 or the pressure ports 7 and 8 can be removed, or can also be supplied externally is.

Die in den Stopfbuchsenraum 4 eingetretene Flüssigkeit reinigt die Stopfbuchsendichtungen 4a und 4b und die Kolbenstange 3, die in Fig. II z.B.The liquid that has entered the stuffing box chamber 4 cleans the Stuffing box seals 4a and 4b and the piston rod 3 shown e.g.

als Plunger wirkt.acts as a plunger.

Der Austritt der bei 10, 11 und 12 eingeführten Reinigungsflüssigkeit kann über die Lippen der Stopfbuchsendichtungen 4a, 4b erfolgen oder durch entsprechende Austrittskanäle 10a, lla und 12a.The exit of the cleaning liquid introduced at 10, 11 and 12 can be done via the lips of the gland seals 4a, 4b or by corresponding Outlet channels 10a, 11a and 12a.

Der Pumpenkolben 2 ist in bekannter Weise mit den Kolbendichtungen 2a und 2b versehen, die erfindungsgemäß über den Kolben-Reinigungskanal 9 gereinigt werden.The pump piston 2 is in a known manner with the piston seals 2a and 2b, which are cleaned via the piston cleaning channel 9 according to the invention will.

Die Zuführung der Reinigungsflüssigkeit für die Reinigung des Pumpenkolbens 2 erfolgt erfindungsgemäß durch die Zubringerkanäle 9a, 9b oder 9c.The supply of cleaning fluid for cleaning the pump piston 2 takes place according to the invention through the feeder channels 9a, 9b or 9c.
