Description

Die Erfindung richtet sich auf eine Misch- und Dosier­vorrichtung für Mauermörtel, Estrich od.dgl. mit zwei gesonderten Einlaßöffnungen für die Mörtelkomponenten, wie Sand und Zement, einer den Einlaßöffnungen nachge­ordneten Mischeinrichtung und einer austragsseitigen Auslaßöffnung.The invention is directed to a mixing and metering device for masonry mortar, screed or the like. with two separate inlet openings for the mortar components, such as sand and cement, a mixing device arranged downstream of the inlet openings and an outlet opening on the discharge side.

Derartige Vorrichtungen werden benötigt, um aus an sich bekannten Vorratssilos, in welchen die einzelnen Mörtelkomponenten gesondert bevorratet werden, diese baustellenseitig dosiert auszutragen und zu mischen.Devices of this type are required in order to discharge and mix them in a metered manner on the construction site from storage silos which are known per se and in which the individual mortar components are stored separately.

Bei neueren Entwicklungen betreffend Vorrichtungen dieser Art ging man davon aus, daß zur Erzielung einer universellen Einsatzbarkeit, d.h. auch für Anwendungs­bereiche, bei welchen eine sehr hohe Dosiergenauigkeit erforderlich ist, die Dosierung der Komponenten exakt volumetrisch erfolgen müsse. Hierzu wurden Fächerräder als Entnahme- und Dosiereinrichtungen entwickelt, wel­che dann wiederum eine gesonderte Mischeinrichtung be­schickten.In recent developments relating to devices of this type, it was assumed that the components were dosed exactly in order to achieve universal applicability, ie also for areas of application in which very high dosing accuracy is required must be done volumetrically. For this purpose, fan wheels were developed as removal and dosing devices, which in turn fed a separate mixing device.

Allerdings ist bei vielen, eine große Masse des Bauvo­lumens ausmachenden Anwendungsfällen, z.B. beim Bau von Einfamilienhäusern, eine sehr hohe Dosiergenauig­keit nicht erforderlich.However, in many applications that make up a large mass of the construction volume, e.g. when building single-family houses, very high dosing accuracy is not required.

Hiervon ausgehend liegt der Erfindung die Aufgabe zu­grunde, eine Vorrichtung der eingangs genannten Art so auszugestalten, daß diese sich aufgrund einer einfa­chen und robusten Konstruktion kostengünstig herstel­len läßt und dabei eine hohe Betriebssicherheit bei geringem Wartungsaufwand aufweist.Proceeding from this, the invention is based on the object of designing a device of the type mentioned at the outset in such a way that it can be produced inexpensively on account of a simple and robust construction and at the same time has a high level of operational reliability with little maintenance.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß unterhalb jeder Einlaßöffnung ein gesonderter Förder- und Dosierkanal mit je einer Dosierschnecke angeordnet ist, wobei die parallel laufenden Dosierkanäle in einen nachgeordneten Mischraum münden, dem wiederum die Austragsöffnung nachgeordnet ist, wobei in dem Mischraum koaxial mit den Dosierschnecken, mit diesen in Drehverbindung stehende Mischelemente angeordnet sind.This object is achieved in that a separate conveying and metering channel, each with a metering screw, is arranged below each inlet opening, the parallel metering channels opening into a downstream mixing chamber, which in turn is followed by the discharge opening, in the mixing room coaxially with the metering screws , are arranged with these in rotating connection mixing elements.

Eine derartige Konstruktion läßt sich mit geringem baulichen Aufwand realisieren, weist nur einen gerin­gen Raumbedarf auf und erreicht gleichwohl eine rela­tiv hohe, jedenfalls für den ganz überwiegenden Teil aller Anwendungsfälle ausreichende Dosiergenauigkeit.Such a construction can be implemented with little construction effort, requires only a small amount of space and nevertheless achieves a relatively high dosing accuracy, which is sufficient for the vast majority of all applications.

In weiterer Ausgestaltung der Erfindung ist vorgese­hen, daß in jedem Förderkanal koaxial zu den Dosier­schnecken und mit diesen in Drehverbindung stehende Förder- und Auflockerungselemente angeordnet sind. Durch diese Elemente wird erreicht, daß die durch die Einlaßöffnungen eintretenden Komponenten aufgelockert werden und in diesen gegebenenfalls vorhandene Klumpen zerkleinert werden, so daß ein kontinuierlicher Mate­rialnachfluß ohne die Gefahr einer Verstopfung oder die Dosiergenauigkeit der nachgeordneten Dosier­schnecken beeinträchtigenden Förderdiskontinuität be­steht.In a further embodiment of the invention it is provided that conveying and loosening elements which are in rotary connection are arranged in each conveying channel coaxially with the metering screws and with them. These elements ensure that the components entering through the inlet openings are loosened and any lumps present in them are crushed, so that there is a continuous flow of material without the risk of blockage or the metering accuracy of the downstream metering screws, which adversely affects delivery discontinuity.

Günstigerweise ist weiterhin vorgesehen, daß ein ein­ziger Antriebsmotor über jeweils individuelle Getrie­beabschnitte je eine durchgehende Welle in jedem Fä­cher- und Dosierkanal antreibt. Auf dieser durchge­henden Welle können auch die Mischelemente in dem Mischraum angeordnet sein. Das Dosierverhältnis für die einzelnen Komponenten, z.B. Sand und Zement, wird durch Einstellung des Übersetzungsverhältnisses der Getriebeabschnitte zueinander vorgegeben. Es kann hier ein Getriebe mit veränderbarem Übersetzungsverhältnis zum Einsatz kommen oder aber eine den zumeist vorkom­menden Anforderungen entsprechende Übersetzung fest eingestellt werden.Conveniently, it is further provided that a single drive motor drives a continuous shaft in each fan and metering channel via individual gear sections. The mixing elements can also be arranged in the mixing space on this continuous shaft. The dosing ratio for the individual components, e.g. Sand and cement is specified by adjusting the gear ratio of the gear sections to one another. A gearbox with a variable transmission ratio can be used here, or a transmission can be permanently set to meet the most common requirements.

Mit Vorteil sind weiterhin Anflanscheinrichtungen zur Anbringung an einem Vorratssilo für die Komponenten mit wenigstens einer im wesentlichen vertikalen Trenn­wand und gesonderten Austragsöffnungen für die einzel­nen Komponenten vorgesehen. Die Anflanscheinrichtungen sind dabei so ausgebildet, daß die Auslaßöffnungen des Vorratssilos mit den Einlaßöffnungen fluchten oder über Schachtabschnitte in Verbindung gebracht werden.Flange devices for attachment to a storage silo for the components with at least one essentially vertical partition wall and separate discharge openings for the individual components are also advantageously provided. The flange devices are designed so that the outlet openings of the storage silo are aligned with the inlet openings or are brought into connection via shaft sections.

Nachfolgend wird die Erfindung anhand eines bevorzug­ten Ausführungsbeispiels in Verbindung mit der Zeich­nung näher beschrieben. Dies zeigt eine perspektivi­sche Darstellung einer erfindungsgemäßen Vorrichtung teilweise aufgebrochen.The invention is described in more detail below on the basis of a preferred exemplary embodiment in conjunction with the drawing. This shows a perspective view of a device according to the invention partially broken away.

In der Zeichnung ist der untere Teil eines Vorratssi­los 1 dargestellt. Dieses weist eine vertikal verlau­fende Trennwand 2 auf, welche das Vorratssilo 1 in zwei Teilbehälter 3, 4 teilt, wovon der eine, größere für Sand und der andere, kleinere für Zement bestimmt ist.In the drawing, the lower part of a storage silo 1 is shown. This has a vertical partition 2 which divides the storage silo 1 into two sub-containers 3, 4, one of which is intended for sand and the other, smaller for cement.

Am unteren Ende jedes Teilbehälters 3, 4 ist eine Aus­laßöffnung 5, 6 vorgesehen, an welche sich jeweils ein Schachtteil 7, 8 anschließt. Diese Schachtteile 7, 8 sind über einen nur schematisch dargestellten Flansch 9 mit der erfindungsgemäßen Vorrichtung 10 verbunden, welche im Anschluß an den Flansch 9 korrespondierende, getrennte Schächte 11, 12 aufweist, an deren Oberseite jeweils gesonderte Einlaßöffnungen für die beiden Kom­ponenten vorgesehen sind.At the lower end of each partial container 3, 4 there is an outlet opening 5, 6, to each of which a shaft part 7, 8 connects. These shaft parts 7, 8 are connected via a flange 9, shown only schematically, to the device 10 according to the invention, which has corresponding separate shafts 11, 12 following the flange 9, on the upper side of which separate inlet openings are provided for the two components.

Die Vorrichtung 10 weist zwei parallel zueinander ver­laufende Förder- und Dosierkanäle 13, 14 auf, welche sich unmittelbar unter den Auslaßöffnungen der Schachtteile 11, 12 diesen jeweils zugeordnet und von­einander getrennt befinden.The device 10 has two conveying and metering channels 13, 14 which run parallel to one another and which are located directly below the outlet openings of the shaft parts 11, 12 and are each separated from them.

In den Förder- und Dosierkanälen 13, 14 verläuft je­weils eine drehangetriebene Welle 15, 16, welche an der in Austragsrichtung gesehen vorderen Gehäusestirn­wand 17 an einer Zwischenwand 18 und an der in Aus­tragsrichtung gesehen hinteren Gehäusestirnwand 19 ge­lagert und über einen Motor 20 angetrieben sind. Dem Motor 20 sind Getriebeabschnitte 21, 22 für jede der Wellen 15, 16 nachgeordnet, wobei das Übersetzungsver­hältnis der Getriebeabschnitte 21, 22 die Relativdreh­zahl der Wellen 15, 16 und damit die Fördermenge von in einem Dosierabschnitt 23 angeordneten Dosierschnek­ken 24, 25 vorgibt.A rotating shaft 15, 16 runs in the conveying and metering channels 13, 14, which are mounted on the front housing end wall 17 seen in the discharge direction on an intermediate wall 18 and on the rear housing end wall 19 seen in the discharge direction and driven by a motor 20. Gear sections 21, 22 for each of the shafts 15, 16 are arranged downstream of the motor 20, the transmission ratio of the gear sections 21, 22 specifying the relative rotational speed of the shafts 15, 16 and thus the delivery rate of metering screws 24, 25 arranged in a metering section 23.

In Förderrichtung gesehen vor den Dosierschnecken 24, 25 sind unterhalb der die Einlaßöffnungen bildenden Schachtabschnitte 11, 12 an den Wellen 15, 16 Auf­lockerungselemente 26 zusammen mit in der Zeichnung nicht dargestellten Förderelementen angeordnet. Durch die Auflockerungselemente 26 werden Materialbrocken aufgebrochen, so daß eine kontinuierliche Weiterför­derung durch die Förderelemente aus diesem Auflocke­rungsbereich 27 in den Dosierbereich 23 erfolgen kann.Viewed in the conveying direction in front of the metering screws 24, 25, loosening elements 26 are arranged below the shaft sections 11, 12 forming the inlet openings on the shafts 15, 16 together with conveying elements not shown in the drawing. Lumps of material are broken up by the loosening elements 26, so that continuous conveying through the conveying elements can take place from this loosening area 27 into the metering area 23.

Zwischen der Zwischenwand 18 und der Stirnwand 19 ist eine Mischkammer 28 vorgesehen, deren Länge den Misch­bereich 29 vorgibt. In diese Mischkammer 28 mündet eine Wasserzuleitung 30 mit einem vorgeschalteten Durchflußregler 31, welcher in der Zeichnung lediglich schematisch angedeutet ist.A mixing chamber 28 is provided between the intermediate wall 18 and the end wall 19, the length of which defines the mixing region 29. A water supply line 30 with an upstream flow regulator 31 opens into this mixing chamber 28, which is only indicated schematically in the drawing.

In die Mischkammer 28 münden Durchlaßöffnungen 32, 33 aus den Dosierabschnitten 23. Dementsprechend erfolgt in der Mischkammer 28 eine Durchmischung der durch die Öffnungen 32, 33 gesondert dosierten Komponenten. Die Durchmischung wird mittels auf den Wellen 15, 16 sit­zender Mischelemente 34 bewerkstelligt.Passage openings 32, 33 from the metering sections 23 open into the mixing chamber 28 in the mixing chamber 28 thorough mixing of the components separately metered through the openings 32, 33. The mixing is accomplished by means of mixing elements 34 seated on the shafts 15, 16.

In der Stirnwand 19 ist eine Auslaßöffnung 35 ausge­bildet, durch welche verarbeitungsfertiger Mörtel oder Estrich ausgetragen wird.An outlet opening 35 is formed in the end wall 19, through which ready-to-use mortar or screed is discharged.
