Description

Die Erfindung betrifft eine Verbesserung an einer Vorrichtung zum kontinuierlichen Mischen von pulverförmigen oder feinkörnigen Baustoffen mit Wasser sowie zum Fördern des Gemisches mittels einer Pumpe, die einem gegenüber einem Vorratsbehälter schwenkbaren Mischbehälter nachgeschaltet und mit diesem starr verbunden ist, wobei der Baustoff dem zylindrischen Mischbehälter aus dem Vorratsbehälter durch eine im wesentlichen denselben Querschnitt wie der Mischbehälter aufweisende Aussparung in der Wand des Vorratsbehälters zuführbar ist.The invention relates to an improvement in a device for the continuous mixing of powdery or fine-grained building materials with water and for conveying the mixture by means of a pump which is connected downstream of a mixing container which can be pivoted relative to a storage container and is rigidly connected to the latter, the building material separating the cylindrical mixing container from the Storage container can be fed through a recess in the wall of the storage container having essentially the same cross section as the mixing container.

Vorrichtungen dieser Art weisen entweder, wie z.B. die Vorrichtung nach DE-OS 2 257 613, ein lotrecht angeordnetes Mischbehälterrohr auf, das zu Reinigungszwecken aus einer verriegelten Stellung um eine lotrechte Achse von dem Vorratsbehälter abgeschwenkt werden kann, oder, wie z.B. die Vorrichtung nach DE-OS 24 20 023, ein Mischbehälterrohr auf, das gegenüber einem lotrechten Zulaufstutzen bzw. gegenüber einem Vorratsbehälter mit einem durch einen lotrechten Trichter gebildeten Auslaß in zur Horizontalen geneigter Lage angebracht ist.Devices of this type either have, e.g. the device according to DE-OS 2 257 613, a vertically arranged mixing container tube, which can be pivoted from a locked position about a vertical axis from the storage container for cleaning purposes, or, e.g. the device according to DE-OS 24 20 023, a mixing container tube, which is attached to a vertical inlet connection or to a storage container with an outlet formed by a vertical funnel in an inclined position to the horizontal.

Bei Vorrichtungen dieser letztgenannten Art wurde festgestellt, daß z.B. Trockenmörtel auf Gipsbasis aufgrund dessen sehr feinkörnigen Aufbas häufig zu Betriebsstörungen führt. Diese sind darauf zurückzuführen, daß sich das feinkörnige Gut an der Welle der im oberen Teil des Mischbehälters angeordneten Förderschnecke ansetzt und so eine gleichmäßige Dosierung und eine ausreichend wirksame Entlüftung verhindert. Dies hat zur Folge, daß das Mischgut aus der Förderpumpe eine wechselnde Konsistenz aufweist oder aufgrund eingeschlossener Luftblasen stoßweise austritt.Devices of this latter type have been found to e.g. Gypsum-based dry mortar often leads to malfunctions due to its very fine-grained base. These are due to the fact that the fine-grained material attaches to the shaft of the screw conveyor arranged in the upper part of the mixing container and thus prevents uniform metering and sufficiently effective ventilation. The result of this is that the mix from the feed pump has a changing consistency or comes out intermittently due to trapped air bubbles.

Bei lotrecht angeordneten Mischbehältern bekannter Art hingegen führen Trockenmörtel mit grobem Kornaufbau und Zement als Bindemittel häufig zu Anlaufschwierigkeiten, zu Verstopfungen und auch zu einer nicht vollständigen Benetzung des Trockenmörtels, was im aufgebrachten Putz zu Rißbildungen führen kann.In the case of vertically arranged mixing containers of known type, on the other hand, dry mortar with a coarse grain structure and cement as a binder frequently lead to starting difficulties, blockages and also incomplete wetting of the dry mortar, which can lead to cracking in the applied plaster.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Misch- und Förder-Vorrichtung der eingangs genannten Art in der Weise zu verbessern, daß mit ihr Trockenmörtel mit unterschiedlichem Kornaufbau störungsfrei verarbeitet werden kann.The invention is therefore based on the object to improve a mixing and conveying device of the type mentioned in such a way that dry mortar with different grain structure can be processed without problems.

Gelöst wird diese Aufgabe mit den Mitteln, wie sie im Kennzeichen des Patentanspruches 1 aufgeführt sind.This problem is solved with the means as listed in the characterizing part of claim 1.

Die durch die Erfindung erzielten Vorteile sind zum einen darin zu sehen, daß der Mischbehälter während des Betriebs der Pumpe leicht in die jeweils für die Korngröße günstigste Stellung geschwenkt werden kann, wenn beispielsweise aus dem Vorratsbehälter Material mit gröberem Korn nachgefördert wird.The advantages achieved by the invention can be seen, on the one hand, in the fact that the mixing container can easily be pivoted into the position most favorable for the grain size during operation of the pump, for example if material with coarser grain is conveyed from the storage container.

Die schwenkbare Anordnung des Mischbehälters hat auch noch den weiteren Vorteil, daß an die Vorrichtung von Fall zu Fall Pumpen unterschiedlicher Länge oder auch mehrstufige Pumpen angeschlossen werden können, um auf diese Weise einen höheren Druck zu erzeugen, der beispielsweise beim Verputzen von Außenfassaden notwendig sein kann.The pivoting arrangement of the mixing container also has the further advantage that pumps of different lengths or multi-stage pumps can be connected to the device from case to case in order to generate a higher pressure in this way, which may be necessary, for example, when plastering external facades .

Die Lagerung des aus Mischbehälter und Förderpumpe bestehenden Bauteils kann derart erfolgen, daß der Mischbehälter einen die Eintrittsöffnung begrenzenden Ringflansch aufweist, der in einem die Austrittsöffnung des Vorratsbehälters begrenzenden Halb-Ringbund gelagert ist. Der Vorteil eines Schwenklagers, bei dem der Ringflansch nur von einem Halbringbung umfaßt wird, besteht in einer einfacheren und schnell durchführbaren Demontage, was sich sowohl bei der Reinigung als auch beim Transport der Vorrichtung vorteilhaft auswirkt.The component consisting of the mixing container and feed pump can be stored in such a way that the mixing container has an annular flange which delimits the inlet opening and is mounted in a half-ring collar delimiting the outlet opening of the storage container. The advantage of a swivel bearing, in which the ring flange is only encompassed by a half ring, consists in a simpler and quicker disassembly, which has an advantageous effect both when cleaning and when transporting the device.

Die Anordnung des Ringflansches derart, daß er - in Richtung der Mischbehalterschwenkachse gesehen - das gegenüber der Langsachse des Mischbehälters außermittige Ende eines schräg nach oben gerichteten seitlichen Stutzens des Mischbehälters umfaßt, hat den Vorteil, daß das Einbringen des Trockengutes aus dem Vorratsbehälter erleichtert wird und daß bei geneigtem Mischbehälter im Bereich zwischen dem Ringflansch und der Innenwand des Mischbehälters Ablagerungen vermieden werden und eine gleichmäßige Beaufschlagung des Mischbehälters mit Trockengut gewährleistet wird. Bei im wesentlichen gleichgroßen lichten Querschnitten des an dem Stutzen angeordneten Flansches und des Mischbehälters werden in dem Bereich zwischen dem Flansch und dem unter dem Stutzen gelegenen kreisförmigen Querschnitt des Mischbehälters gleichmäßig geneigte Schrägflächen geschaffen, die eine einwandfreie Beschickung des Mischbehälters gewährleisten. Bei einer solchen Ausbildung des Stutzens liegt die zur Längsachse des Mischbehälters versetzte Schwenkachse oberhalb der Längsachse des Mischbehälters.The arrangement of the ring flange such that it - seen in the direction of the mixing container pivot axis - comprises the eccentric end of an obliquely upward lateral connection of the mixing container relative to the longitudinal axis of the mixing container has the advantage that the introduction of the dry material from the storage container is facilitated and that in the case of an inclined mixing container, deposits are avoided in the area between the ring flange and the inner wall of the mixing container and a uniform loading of the mixing container with dry material is ensured. If the cross section of the flange and the mixing container arranged on the connecting piece is of substantially the same size, evenly inclined inclined surfaces are created in the area between the flange and the circular cross section of the mixing container located under the connecting piece, which ensure that the mixing container is loaded correctly. With such a design of the nozzle, the pivot axis offset from the longitudinal axis of the mixing container lies above the longitudinal axis of the mixing container.

Wird als Vorratsbehälter ein lotrechter kreiszylindrischer Behälter verwendet, so ist dieser vorteilhafterweise so angeordnet, daß die Schwenkachse des Mischbehälters die die lotrechte Achse des kreiszylindrischen Vorratsbehälters bildende, mit radial angeordneten Förderflügeln bestückte Welle schneidet.If a vertical circular cylindrical container is used as the storage container, it is advantageously arranged such that the pivot axis of the mixing container intersects the shaft which forms the vertical axis of the circular cylindrical storage container and is equipped with radially arranged conveyor vanes.

Ist der Vorratsbehälter als ein im wesentlichen waagerecht liegender, eine Förderschnecke aufweisender Zylinder ausgebildet, so sind Vorratsbehälter und Förderschnecke so angeordnet, daß deren Achse mit der Schwenkachse des Mischbehälters fluchtet oder auch oberhalb dieser gelegen ist.If the storage container is designed as a substantially horizontally lying cylinder having a screw conveyor, the storage container and screw conveyor are arranged in such a way that their axis is aligned with the pivot axis of the mixing container or is also located above it.

In der Zeichnung ist ein Ausführungsbeispiel der Vorrichtung gemäß der Erfindung in schematischer Weise dargestellt. Es zeigt:

  • Fig. 1 eine Seitenansicht der Vorrichtung;
  • Fig. 2 eine Stirnseitenansicht der Vorrichtung mit in strichpunktierten Linien eingezeichnetem geneigtem Mischbehälter, und
  • Fig. 3 einen waagerechten Schnitt durch den Mischbehälter in der Ebene der Schwenkachse.
In the drawing, an embodiment of the device according to the invention is shown in a schematic manner. It shows:
  • Figure 1 is a side view of the device.
  • Fig. 2 is an end view of the device with an inclined mixing container shown in dash-dotted lines, and
  • Fig. 3 shows a horizontal section through the mixing container in the plane of the pivot axis.

Im oberen Teil des Mischbehälters 1 ist eine Zubringerschnecke 11 angeordnet, mit deren Welle im unteren Teil des Mischbehälters 1 Mischwerkze ge 12 verbunden sind. Oberhalb der Mischwerkzeuge 12 weist, der Mischbehälter 1 einen an eine Wasserleitung angeschlossenen Stutzen 13 auf. Im mittleren Bereich der Zubringerschnecke 11 ist gegenüber dem Stutzen 13 an dem an dieser Stelle etwas ausgebauchten Mischbehaltermantel ein Ringflansch 14 an einem seitlichen Stutzen des Behältermentels angebracht. Dem Mischbehälter 1 ist eine Schneckenpumpe 2 mit Auslaufstutzen 3 nachgeschaltet, die mit der Welle der Zubringer-schnecke 11 fluchtet und über diese von dem Motor 4 angetrieben wird. Auf der Seite des Ringflansches 14 ist seitlich des Mischbehälters 1 der Vorratsbehälter 5 angeordnet, an dessen dem Mischbehälter 1 zugewandtem Wandteil 51 ein Halbringbund 52 angeordnet ist, der dem Ringflansch 14 als Drehlager dient. Den Boden des Vorratsbehälters 5 durchsetzt eine von. einem Motor 53 angetriebene Welle 54, auf die ein Flügelrad mit schaufelförmig ausgebildeten Flügeln 55 aufgekeilt ist. Der Vorratsbehälter 5 ruht auf einem fahrbaren Gestell 6.In the upper part of the mixing container 1, a feed screw 11 is arranged, with the shaft in the lower part of the mixing container 1 mixing tools GE 12 are connected. Above the mixing tools 12, the mixing container 1 has a connecting piece 13 connected to a water pipe. In the central region of the feed screw 11, an annular flange 14 is attached to a lateral connection of the container shell opposite the connection 13 at the mixing container jacket which is somewhat bulged at this point. The mixing container 1 is followed by a screw pump 2 with outlet 3, which is aligned with the shaft of the feeder screw 11 and driven by the motor 4. On the side of the ring flange 14, the storage container 5 is arranged on the side of the mixing container 1, on the wall part 51 facing the mixing container 1 a half-ring collar 52 is arranged, which serves as a rotary bearing for the ring flange 14. The bottom of the storage container 5 passes through one of. a motor 53 driven shaft 54 onto which an impeller with blades 55 in the form of blades is wedged. The storage container 5 rests on a mobile frame 6.

Wie aus Fig. 2 ersichtlich ist, sind am Rand des Ringflansches 14 Zähne vorgesehen, die im Zusammenwirken mit einer Sperrklinke die Feststellung des Mischbehälters 1 in einer gewünschten Neigungslage ermöglichen. In dieser Lage kann der Mischbehälter 1 mittels an dem Ringflansch 14 angreifender Klemmvorrichtungen oder auch mittels Schrauben fixiert werden.As can be seen from FIG. 2, 14 teeth are provided on the edge of the ring flange which, in cooperation with a pawl, enable the mixing container 1 to be fixed in a desired inclined position. In this position, the mixing container 1 can be fixed by means of clamping devices acting on the ring flange 14 or also by means of screws.

Die Entlüftung des Trockengutes erfolgt auf bekannte Weise entlang der Welle der Zubringerschnecke 11 durch am oberen Ende des Mischbehälters 1 vorgesehene Entlüftungsöffnungen oder durch den Vorratsbehälter 5.The drying of the dry material takes place in a known manner along the shaft of the feed screw 11 through ventilation openings provided at the upper end of the mixing container 1 or through the storage container 5.

Aus der in Fig. 2 in strichpunktierten Linien eingezeichneten geneigten Lage des Mischbehälters 1' ist ersichtlich, daß der Öffnungsquerschnitt des Ringflansches 14 im wesentlichen außerhalb oberhalb der Längsachse des Mischbehälters 1 liegt, wodurch ein gleichmäßiges Einfließen des Trockenguts erleichtert wird.From the inclined position of the mixing container 1 'shown in dash-dotted lines in FIG. 2, it can be seen that the opening cross section of the annular flange 14 lies essentially outside above the longitudinal axis of the mixing container 1, thereby facilitating a uniform inflow of the dry material.
