Description
Die Erfindung betrifft eine Vorrichtung zum Mischen eines als Mörtel- oder Estrichmischung aus mehreren Komponenten gebildeten Mischguts mit einem ein durch eine Mischerwelle drehbares Mischwerk enthaltenden, über eine mittels eines Deckels verschließbare Befüllöffnung mit zumindest einer Komponente des Mischguts befüllbaren Druckkessel, dessen im Arbeitsbetrieb mit Druck beaufschlagbarer Innenraum ein von dem Mischwerk durchsetztes Mischvolumen aufweist, und einem Motor zum Drehantrieb der Mischerwelle.The invention relates to a device for mixing a mixture formed as a mortar or screed mixture of several components mixed with a rotatable by a mixer shaft mixing, via a closable by means of a lid filling opening with at least one component of the mixable filling pressure vessel, which can be acted upon in operation with pressure Interior has an interspersed by the mixer mixing volume, and a motor for rotary drive of the mixer shaft.
Seit der Vorstellung des ersten Estrichförderers im Jahre 1966 durch die Fa. Putzmeister Werk werden Sand, Zement und Wasser in einem zylinderförmigen Druckbehälter als zentrales Funktionselement gemischt und anschließend durch eine Förderleitung zum Verlegeort gepumpt. Ein in den Druckbehälter geleiteter Luftstrom hilft als Luftpolster oberhalb der Estrichmischung, zusammen mit dem kontinuierlich drehenden Mischwerk, bei der Austragung des Materials in den Abgang. Problematisch ist häufig, dass Bediener den Druckkessel vollständig mit Material befüllen, um etwa die Befüllintervalle zu vergrößern. Bei vollständiger Befüllung kommt es aber zu Verdichtungseffekten im Mischgut, die kurzzeitig eine erhebliche Überhöhung der nötigen Antriebsleistung des Motors erfordern. D.h., die Vorrichtung bzw. Maschine muss der Fehlbedienung wegen mit einem deutlich leistungsfähigeren Antrieb ausgestattet werden, als dies bei korrekter Bedienung erforderlich wäre.Since the first screed conveyor was introduced in 1966 by the company Putzmeister Werk, sand, cement and water are mixed in a cylindrical pressure vessel as a central functional element and then pumped through a delivery line to the installation site. An airflow directed into the pressure vessel, as a cushion of air above the screed mixture, together with the continuously rotating mixer, helps to discharge the material into the outlet. The problem is often that operators fill the pressure vessel completely with material, for example to increase the filling intervals. When fully filled comes but it to compaction effects in the mix, which require a short time a significant increase in the necessary drive power of the engine. That is, the device or machine must be equipped with a much more powerful drive because of incorrect operation, as would be required for correct operation.
Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, die im Stand der Technik bekannten Vorrichtungen weiter zu verbessern und eine hinsichtlich der erforderlichen Motorleistung optimierte und gegenüber Fehlbedienung abgesicherte Konstruktion anzugeben.Proceeding from this, the object of the invention is to further improve the devices known in the prior art and to specify a construction optimized with regard to the required engine power and secured against incorrect operation.
Zur Lösung dieser Aufgabe wird die im Patentanspruch 1 angegebene Merkmalskombination vorgeschlagen. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.To solve this problem, the feature combination specified in claim 1 is proposed. Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.
Die Erfindung geht von dem Gedanken aus, ein Ausweich- bzw. Ausgleichsvolumen zu schaffen, das durch den Bediener nicht mit Material befüllt werden kann. Dementsprechend wird erfindungsgemäß vorgeschlagen, dass der Innenraum ein oberhalb bzw. über der Höhe der Befüllöffnung angeordnetes Ausweichvolumen umfasst, wobei das Ausweichvolumen jedenfalls bei geschlossenem Deckel mit dem Mischvolumen kommuniziert und dem Mischgut beim Mischen Raum zum Ausweichen gibt. Durch die Anordnung des Ausweichvolumens oberhalb der Befüllöffnung ist es dem Bediener ohne besonderen Aufwand nicht möglich, den Druckbehälter unzulässig zu überfüllen. Zugleich wird sichergestellt, dass ein genügend großer Freiraum zur Verfügung steht, in welchen Material beim Mischen verdrängt werden kann. Weiterhin wird so ein Bereich freigehalten, der beim Einleiten von Druckluft als anfänglicher Kompressionsraum dienen kann.The invention is based on the idea of creating a compensating volume that can not be filled with material by the operator. Accordingly, it is proposed according to the invention that the interior comprises a deflection volume arranged above or above the height of the filling opening, wherein the escape volume communicates with the mixing volume at any rate when the lid is closed, and gives the mixture space to avoid during mixing. Due to the arrangement of the Dodge volume above the filling, it is the operator without special effort not possible to overfill the pressure vessel. At the same time it is ensured that a sufficiently large free space is available, in which material can be displaced during mixing. Furthermore, such an area is kept free, which can serve as an initial compression space when introducing compressed air.
Eine baulich besonders vorteilhafte Konstruktion sieht vor, dass der Deckel das Ausweichvolumen begrenzt.A structurally particularly advantageous construction provides that the lid limits the escape volume.
Eine weitere Verbesserung lässt sich dadurch erreichen, dass der Deckel als auf die Befüllöffnung aufsetzbare, nach oben geschlossene Haube ausgebildet ist.A further improvement can be achieved in that the cover is designed as an attachable to the filling, upwardly closed hood.
In diesem Zusammenhang ist es auch günstig, wenn der Deckel über ein Deckelscharnier gegen die Befüllöffnung verschwenkbar ist.In this context, it is also advantageous if the lid is pivotable against the filling opening via a cover hinge.
Zur Schaffung eines Freiraums oberhalb der Befüllöffnung ist es auch vorteilhaft, wenn der Druckkessel an seiner Oberseite einen nach oben sich erstreckenden Dom zur Begrenzung des Ausweichvolumens aufweist.To create a free space above the filling opening, it is also advantageous if the pressure vessel has on its upper side an upwardly extending dome for limiting the escape volume.
Eine weitere vorteilhafte Ausgestaltung sieht vor, dass die Befüllöffnung durch den unteren Rand eines von oben in den Innenraum hineinragenden Einfüllstutzens gebildet ist, und dass der den Einfüllstutzen umgebende Bereich des Innenraums das Ausweichvolumen bildet.A further advantageous embodiment provides that the filling opening through the lower edge of a top is formed in the interior projecting filler neck, and that the surrounding the filler neck portion of the interior forms the escape volume.
In dieser Ausgestaltung ist es auch von Vorteil, wenn die horizontal angeordnete Mischerwelle exzentrisch bezüglich einer Horizontalmittelachse des Druckkessels nach unten versetzt oder versetzbar ist.In this embodiment, it is also advantageous if the horizontally arranged mixer shaft is offset eccentrically with respect to a horizontal center axis of the pressure vessel down or displaceable.
Um genügend Verdrängungsraum zu schaffen, sollte das Ausweichvolumen mindestens 1/10, vorzugsweise mindestens 1/5 und bevorzugt etwa 1/4 des Gesamtvolumens des Innenraums umfassen.To provide sufficient displacement space, the escape volume should be at least 1/10, preferably at least 1/5 and preferably about 1/4 of the total volume of the interior.
In der erfindungsgemäßen Konfiguration ist es vorgesehen, dass das Mischwerk eine auf der Mischerwelle sitzende Mischwendel oder eine Mehrzahl von quer zur Mischerwelle abstehende Mischflügel besitzt.In the configuration according to the invention, it is provided that the mixing plant has a mixing spiral sitting on the mixer shaft or a plurality of mixing blades projecting transversely to the mixer shaft.
Um das Mischgut auszubringen, ist es vorteilhaft, wenn der Druckkessel einen Druckluftanschluss für einen mittels des Motors betriebenen Kompressor aufweist. Auch hier kann das Ausgleichsvolumen vorteilhaft für die Begrenzung der erforderlichen maximalen Motorleistung wirken.In order to dispense the mix, it is advantageous if the pressure vessel has a compressed air connection for a compressor operated by means of the engine. Again, the compensation volume can be beneficial for limiting the required maximum engine power.
In der erfindungsgemäßen Konfiguration ist es weiter vorteilhaft, wenn der Druckkessel an seiner Unterseite einen Anschluss für eine Förderleitung zum Austragen des Mischguts aufweist.In the configuration according to the invention, it is also advantageous if the pressure vessel at its bottom having a connection for a delivery line for discharging the mixed material.
Vorteilhafterweise ist der Druckkessel auf einem Fahrgestell für einen Fahrtransport zum Einsatzort angeordnet.Advantageously, the pressure vessel is arranged on a chassis for transport to the place of use.
