Abstract
Description
Die Erfindung richtet sich auf eine Misch- und Dosier-Vorrichtung für Mauermörtel, Estrich od.dgl. gemäß dem Oberbegriff von Anspruch 1.The invention is directed to a mixing and metering device for masonry mortar, screed or the like. according to the preamble of claim 1.
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, for example in the construction of single-family houses, a very high metering accuracy is not required.
Aus der DE-A-31 42 053 ist eine Misch- und Dosiervorrichtung für Mauermörtel bekannt, wobei in einem Mischraum koaxial mit den Dosierschnecken mit diesen in Drehverbindung stehene Mischelemente angeordnet sind.From DE-A-31 42 053 a mixing and metering device for masonry mortar is known, wherein in a mixing room coaxial with the metering screws mixing elements are arranged with them in rotary connection.
Die DE-C-859 869 zeigt ebenfalls eine Misch- und Dosiervorrichtung für Mauermörtel mit zwei gesonderten Einlaßöffnungen für die zu dosierenden Mörtelkomponenten, wie Sand und Zement, einer den Einlaßöffnungen nachgeordneten Mischeinrichtung und einer austragsseitigen Auslaßöffnung, wobei unter jeder Einlaßöffnung ein gesonderter Förder- und Dosierkanal mit je einer während des Betriebs der Vorrichtung dauernd angetriebenen Dosierschnecke angeordnet ist, wobei die parallel laufenden Dosierkanäle in einen nachgeordneten, die Mischelemente aufnehmenden Mischraum münden, dem wiederum die Austragsöffnung für das entsprechend dem eingestellten Dosierverhältnis zusammengesetzte Mischgut nachgeordnet ist.DE-C-859 869 also shows a mixing and metering device for masonry mortar with two separate inlet openings for the mortar components to be metered, such as sand and cement, a mixing device downstream of the inlet openings and a discharge-side outlet opening, with a separate conveying and under each inlet opening The metering channel is arranged with a metering screw that is continuously driven during the operation of the device, the metering channels running in parallel opening into a downstream mixing chamber that receives the mixing elements, which in turn is followed by the discharge opening for the mixed material composed according to the set metering ratio.
Die GB-A-7 48 513 beschreibt eine Anordnung von Mischelementen. Diese dienen dort dazu Granulat aufzuwirbeln, um es mit einem flüssig aufgesprühten Kunststoff-Bindematerial zu überziehen, welches unter Druck von oben zugeführt wird.GB-A-7 48 513 describes an arrangement of mixing elements. There they serve to stir up granulate in order to cover it with a liquid sprayed-on plastic binding material, which is supplied under pressure from above.
Eine gattungsgemäße Misch- und Dosiereinrichtung ist aus der EP-A-1 503 353 bekannt.A generic mixing and metering device is known from EP-A-1 503 353.
Der Erfindung liegt die Aufgabe zugrunde, ausgehend von einer von der gattungsbildenden Druckschrift bekannten Vorrichtung zur Herstellung von Mauermörtel diese so weiterzubilden, daß eine kontinuierliche Bereitstellung und Entnahme des fertigen Mischproduktes möglich ist, wie dies insbesondere bei der Verlegung von Estrich an Großbaustellen typisch ist, wobei die Aufbereitung zu einer optimalen Förderkonsistenz, insbesondere von Estrich, führen soll.The invention is based on the object, starting from a device known from the generic document for the production of masonry mortar, to further develop it so that continuous provision and removal of the finished mixed product is possible, as is typical, in particular, when laying screed on large construction sites, whereby the preparation should lead to an optimal delivery consistency, especially of screed.
Durch die Merkmalskombination gemäß dem kennzeichnenden Teil von Anspruch 1, ist es möglich, insbesondere Estrich mit minimalem Bedienungsaufwand auch in großen Quantitäten bereitzustellen, was durch die Kombination der Anordung und Ausgestaltung der Misch- und Förderelemente erreicht wird.Due to the combination of features according to the characterizing part of claim 1, it is possible to provide screed in particular in large quantities with minimal operating effort, which is achieved by the combination of the arrangement and design of the mixing and conveying elements.
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.
