Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Zerkleinern von Feststoffen in inhomogenen Flüssigkeiten, insbesondere Gülle, die ein Gehäuse als Flüssigkeitsaufnahmebehälter enthält, in den zumindest eine Zuführleitung einmündet, der im Bereich zumindest einer Durchtrittsöffnung quer zur Strömungsrichtung der Flüssigkeit ein Schneidwerkzeug mit einem rotierenden Schneidglied und einem ortsfesten Gegenglied aufweist, und der mit einer Austrittsöffnung ausgebildet ist.The The invention relates to a device for comminuting Solids in inhomogeneous liquids, especially manure, the one housing as a liquid receiving container, in the at least one supply line opens, in the region of at least one passage opening transversely to the flow direction the liquid a cutting tool with a rotating cutting member and a stationary Comprising a counter member, and which is formed with an outlet opening.
Eine
solche Vorrichtung ist bekannt (
Bisher sind die Messer und die Flügel der Rotoren jeweils mit einer Bohrung versehen. Bei der Montage der Schneidmesser wird ein Stift in der Bohrung befestigt. Der Stift bildet die Lagerung der Messer in der Rotornut.So far are the knives and the wings each of the rotors is provided with a bore. During installation The cutting knife is a pin mounted in the hole. The pencil forms the bearings of the knives in the rotor groove.
Bei Unebenheiten des Schneidsiebs und bei ungleichmäßigem Verschleiß von Messer und Schneidsieb liegen durch die pendelnde Aufhängung der Messer diese immer flächig auf dem Schneidsieb auf. Jedoch ist in der Nut des Rotors zwischen dem Rücken der Schneidmesser und dem Boden der Nut in den Rotorflügein ein Spalt vorhanden, damit ein Pendeln des Messers möglich ist. Dieser Spalt setzt sich gern mit Feststoffen zu und verhindert dadurch die Pendelmöglichkeit. Infolge des ständigen federbeaufschlagten Kontaktes zwischen Messer und dem Schneidsieb wird Reibungwärme erzeugt. Besonders bei Trockenlauf wird bei mangelnder Abfuhr der Reibungswärme das Messer schnell heiß und verliert seine Härte. Bei Aufhängung des Messers mittels eines Stiftes kann Wärme nur unbefriedigend abgeführt werden.at Unevenness of the cutting wire and uneven wear of knives and cutting screen lie through the swinging suspension of the knife this always flat on the cutting wire. However, in the groove of the rotor is between the back the cutting blade and the bottom of the groove in the rotor blades There is a gap to allow the knife to oscillate. This gap settles like with solids and thus prevents the pendulum option. As a result of the constant spring-loaded contact between knife and the cutting screen becomes frictional heat generated. Especially in dry running is in lack of drainage of frictional heat The knife quickly gets hot and loses his hardness. With suspension the knife by means of a pin heat can dissipate only unsatisfactory.
Schließlich kann der Stift im Laufe des Betriebes ausschlagen und herausfallen. Dann ist das Messer nicht mehr korrekt geführt.Finally, can knock out the pin during operation and fall out. Then the knife is no longer correctly guided.
Gemäß der Erfindung werden die Nut in den Rotorflügeln und der Rücken des Messers jeweils kreisförmig mit dem gleichen Kreisradius ausgeführt.According to the invention become the groove in the rotor blades and the back of the knife in each case circular executed with the same circle radius.
Daher ist kein Stift zur Halterung des Messers erforderlich, vielmehr wird die Pendel-Beweglichkeit dadurch erreicht, dass der Messerrücken und der Nutgrund jeweils ein Gleitlager bilden.Therefore no pin is needed to hold the knife, but rather the pendulum mobility is achieved in that the back of the knife and the Nutgrund each form a plain bearing.
Folgende Vorteile werden erzielt:
- Pendelbeweglichkeit ist zum Ausgleich von Unebenheiten gewährleistet.
- Spaltlose Pendelbeweglichkeit ist gegeben. Es kann kein Schmutz eindringen und das Pendeln blockieren.
- Guter Wärmeübergang zwischen Rotorflügeln und Messer ist dadurch gegeben, dass die Kontaktfläche wesentlich vergrößert worden ist.
- Leichter Ein- und Ausbau bei Wartungsarbeiten.
- Pendulum mobility is guaranteed to compensate for unevenness.
- Slippery pendulum mobility is given. It can not penetrate dirt and block the commuting.
- Good heat transfer between rotor blades and blades is given by the fact that the contact surface has been significantly increased.
- Easy installation and removal during maintenance work.
Die Erfindung wird nachstehend anhand der Zeichnung beispielsweise erläutert.The Invention will be explained below with reference to the drawing, for example.
