Description

Die Erfindung betrifft eine Vorrichtung zum Mischen eines Baustoffs mit Wasser und/oder Verpumpen des bzw. eines Baustoff-Wasser-Gemisches, die in einem fahrbaren Gestell unter einem Vorratstrichter eine Mischkammer mit einem Wassereinlaß und einem um eine senkrechte Achse rotierendenmischwerkzeug und/oder eine Pumpe sowie Antriebeinrichtungen für das Mischwerkzeug und/oder die Pumpe aufweist. Eine solche Vorrichtung ist beispielsweise bekannt aus der DE-AS 21 17 000.The invention relates to a device for mixing a building material with water and / or pumping the or a building material-water mixture, the mixing chamber with a water inlet and a mixing tool rotating about a vertical axis and / or a pump in a mobile frame under a storage funnel and has drive devices for the mixing tool and / or the pump. Such a device is known for example from DE-AS 21 17 000.

Der Erfindung liegt die Aufgabe zugrunde, eine möglichst niedrige und kompakte Vorrichtung zum Mischen und/oder Verpumpen eines Baustoffs zu schaffen.The invention has for its object to provide the lowest possible and most compact device for mixing and / or pumping a building material.

Die Erfindung geht zu diesem Zweck von der eingangs bezeichneten Bauart aus und sieht vor, daß das Gestell im wesentlichen aus einer die Mischkammer bzw. wenigstens einen Teil der Pumpe sowie die Antriebseinrichtungen überdeckenden Haube besteht, die einen kleineren unteren Teil des Trichters in sich aufnimmt, wobei der obere Rand dieses Teils und der obere Rand der Haube im wesentlichen zusammenfallen, und daß auf dem oberen Rand der Haube der übrige, größere Teil des Trichters selbsttragend sitzt.For this purpose, the invention is based on the type described at the beginning and provides that the frame essentially consists of a hood covering the mixing chamber or at least part of the pump and the drive devices, which accommodates a smaller lower part of the funnel, wherein the upper edge of this part and the upper edge of the hood essentially coincide, and that on the upper edge of the hood sits the rest of the larger part of the funnel self-supporting.

Die damit erhaltene, in der Schale tragende Konstruktion ist trotz ihres in der Mitte verengten Querschnitts äußerst stabil. Die Haube, unter der alle Einrichtungen außer dem genannten größeren Teil des Trichters zusammengedrängt und geschützt sind, ergibt damit und mit der geschlossenen Oberfläche, die sie bildet, sowie mit der erwähnten Querschnittsverengung in Kombination mit dem selbsttragend darauf sitzenden Teil des Trichters eine beachtliche Kompaktierung der Vorrichtung. Dadurch, daß der untere Teil des Trichters noch innerhalb der Haube liegt, kommt im Ganzen eine sehr niedrige Anordnung des Trichters und damit geringe Bauhöhe der Vorrichtung zustande; zugleich wird durch das Ansetzen nur eines oberen Teiles des Trichters in der Verbindung zwischen diesem und der Haube der Querschnitt größer, womit der erwähnte selbsttragende Sitz die erforderliche Stabilität erhält.The resulting structure in the shell is extremely stable despite its narrow cross section. The hood, under which all devices except the larger part of the funnel mentioned are pushed together and protected, thus and with the closed surface, the it forms, as well as with the mentioned narrowing of the cross-section in combination with the self-supporting part of the funnel, a considerable compacting of the device. The fact that the lower part of the funnel is still inside the hood results in a very low arrangement of the funnel and thus a low overall height of the device; at the same time, the cross-section becomes larger as a result of the attachment of only an upper part of the funnel in the connection between the latter and the hood, which gives the self-supporting seat mentioned the necessary stability.

Vorzugsweise ist der auf der Haube sitzende Teil des Trichters angeflanscht und in einfacher Weise abnehmbar. Dann läßt sich die Vorrichtung selbst im Kofferraum eines Personenkraftwagens verstauen.The part of the funnel sitting on the hood is preferably flanged and can be removed in a simple manner. Then the device can be stowed even in the trunk of a passenger car.

Nach einer bevorzugten Ausgestaltung der Erfindung ist die Grundfläche der Haube im wesentlichen rechtwinklig, vorzugsweise quadratisch, wobei an jeder Ecke eine Rolle angeordnet ist, und der obere Rand des Trichters hat im wesentlichen gleiche Form wie die Grundfläche der Haube und fluchtet mit dieser.According to a preferred embodiment of the invention, the base of the hood is essentially rectangular, preferably square, with a roller being arranged at each corner, and the upper edge of the funnel has essentially the same shape as the base of the hood and is flush with it.

Damit erhält die Vorrichtung eine prismatische, dem Würfel angenäherte Gesamtform. Diese dient gleichfalls der Kompaktierung. Sie erlaubt es aber auch, die Vorrichtung in einfacher Weise umzulegen, wenn ein entsprechend begrenzter Transportraum das verlangt oder wenn Wartungs- oder Reparaturarbeiten vorgenommen werden sollen. Mit gleicher Form der Haube und des aufgesetzten Trichterteils verbilligt sich die Herstellung.This gives the device a prismatic overall shape approximating the cube. This also serves for compacting. However, it also allows the device to be moved in a simple manner if a correspondingly limited transport space requires this or if maintenance or repair work is to be carried out. With the same shape of the hood and the attached funnel part, the production becomes cheaper.

Im Längsschnitt wird die Vorrichtung in der Regel eine etwa X-förmige Gestalt annehmen. Die Bodenfreiheit der Vorrichtung, d.h. den Abstand zwischen dem unteren Rand der Haube und dem Boden wird man so bemessen, daß die Fußspitzen darunter Platz finden. So wird ein nahes Herantreten und Hantieren an der Vorrichtung möglich, aufgrund der X-Form auch mit eingeknickten Knien.In longitudinal section, the device will generally take an approximately X-shaped shape. The clearance of the device, i.e. the distance between the lower edge of the hood and the floor is measured so that the toes can be placed underneath. This makes it possible to approach and manipulate the device closely, thanks to the X shape, even with knees bent.

Vorzugsweise ist, wenn die Grundfläche der Haube und der obere Rand des Trichters rechteckig sind, der Querschnitt an der Verbindung zwischen Haube und Trichter trotzdem kreisförmig. Damit läßt sich die Verbindung genauer herstellen und die Kraftübertragung wird gleichmäßiger.Preferably, if the base of the hood and the upper edge of the funnel are rectangular, the cross section at the connection between the hood and the funnel is nevertheless circular. This enables the connection to be established more precisely and the power transmission to be more even.

Eine besonders vorteilhafte Abwandlung der Erfindung besteht darin, daß an die Mischkammer mit dem um eine senkrechte Achse rotierenden Mischwerkzeug eine weitere, rohrförmige Mischkammer mit einem um eine waagerechte Achse rotierenden Mischwerkzeug angesetzt ist, die nahe der Grundfläche der Haube verläuft und an die bei Bedarf eine Pumpe angesetzt und ansetzbar ist.A particularly advantageous modification of the invention is that a further tubular mixing chamber with a mixing tool rotating about a horizontal axis is attached to the mixing chamber with the mixing tool rotating about a vertical axis, which runs close to the base of the hood and to which, if necessary Pump is attached and attachable.

Diese Aufteilung der bisherigen Mischkammer in einen senkrechten und einen im Winkel daran angesetzten, waagerechten Teil erniedrigt die Bauhöhe. Sie erlaubt darüberhinaus, da man auch bisher schon immer die Bauhöhe möglichst niedrig zu halten trachtete, eine längere Mischstrecke und damit letztlich eine bessere Durchmischung. Mit der Beibehaltung der senkrechten Mischkammer als Teil der Mischeinrichtung bleibt der wesentliche Vorteil der senkrechten Mischkammer erhalten, daß beim Abschalten der Vorrichtung das Wasser nicht in den vor der Mischkammer vorhandenen trockenen Baustoff hineinläuft.This division of the previous mixing chamber into a vertical and an angled, horizontal part lowers the overall height. In addition, since it has always been tried to keep the overall height as low as possible, it also allows a longer mixing distance and ultimately better mixing. By maintaining the vertical mixing chamber as part of the mixing device, the main advantage of the vertical mixing chamber remains that when the device is switched off, the water does not run into the dry building material in front of the mixing chamber.

Soll die Vorrichtung mischen und pumpen, was meistens der Fall sein wird, so können an die waagerechte Mischkammer alle bekannten Schneckenpumpen angesetzt werden, von der kleinsten bis zur größten; man läßt die Pumpe eben so weit, wie es sich ergibt, aus der Haube herausragen.If the device is to mix and pump, which will usually be the case, all known screw pumps can be attached to the horizontal mixing chamber, from the smallest to the largest; the pump is allowed to protrude from the hood as far as it can be seen.

Soll die Vorrichtung nur Mischvorrichtung sein und daher eine Pumpe entfallen, kann man statt der Pumpe ein kurzes Austragsrohr an die waagerechte Mischkammer ansetzen und die Vorrichtung erhöht anordnen, um den Auslauf in ein Behältnis zu ermöglichen.If the device is only to be a mixing device and therefore a pump is not required, a short discharge pipe can be attached to the horizontal mixing chamber instead of the pump and the device can be arranged in an elevated position to allow it to flow out into a container.

Soll die Vorrichtung nur Pumpvorrichtung sein, etwa in einer langen Pumpleitung als Zwischenstation, so kann man auf beide Mischkammern verzichten und den unteren Teil des Trichters unmittelbar an der Pumpe ausmünden lassen. Man kann aber auch wenigstens die senkrechte Mischkammer oder beide Mischkammern mit oder ohne Mischwerkzeug beibehalten, um das Herstellungs- und/ oder Vertriebsprogramm zu vereinheitlichen.If the device is only to be a pump device, for example in a long pump line as an intermediate station, both mixing chambers can be dispensed with and the lower part of the funnel can be opened directly at the pump. However, it is also possible to maintain at least the vertical mixing chamber or both mixing chambers with or without a mixing tool in order to standardize the manufacturing and / or sales program.

Mischen und Pumpen kommt hauptsächlich für maschinengängig rezeptierte Werktrockenmörtel in Betracht, für Maschinenputze und für Haftbrücken und Untergrund-Vorbehandlungsmittel, blosses Mischen für nicht pumpfähige Werktrockenmörtel, wie Leichtmauermörtel u.ä. und blosses Pumpen neben der erwähnten -Zwischenstation für werksseitig angemischte, z.B. dispersionsgebundene Mörtel, wie Dekorputze u.ä., und mittels eines gesonderten Durchlaufmischers angemischte Mörtel.Mixing and pumping are mainly considered for machine-made pre-mixed dry mortar, for machine plasters and for bonding bridges and substrate pre-treatment agents, mere mixing for non-pumpable pre-dry mortar such as lightweight wall mortar and the like. and mere pumping in addition to the mentioned intermediate station for factory-mixed, e.g. dispersion-bound mortars, such as decorative plasters and the like, and mortars mixed using a separate continuous mixer.

Eine weitere zweckmäßige Ausgestaltung der Erfindung besteht darin, daß das um die waagerechte Achse rotierende Mischwerkzeug von einer die Stirnseite der betreffenden Mischkammer durchsetzenden Welle angetrieben ist und über einen in den Mischkammern angeordneten Winkeltrieb das um die senkrechte Achse rotierende Mischwerkzeug mitnimmt.A further expedient embodiment of the invention is that the mixing tool rotating about the horizontal axis is driven by a shaft passing through the end face of the relevant mixing chamber and takes the rotating tool rotating about the vertical axis with it through an angular drive arranged in the mixing chambers.

Das um die senkrechte Achse rotierende Mischwerkzeug kann dabei einfach an in dem Trichter angeordneten Speichen aufgehängt und an seinem unteren Ende mit einem Ring, an dem der getriebene Kranz des Winkeltriebs angeordnet ist, an der Wandung der Mischkammer geführt sein, wobei diese hier vorzugsweise einen auswechselbaren ringförmigen Abschnitt oder Belag aus einem verschleißarmen Material aufweist.The mixing tool rotating about the vertical axis can simply be suspended from spokes arranged in the funnel and can be guided at the lower end with a ring on which the driven ring of the angular drive is arranged on the wall of the mixing chamber, these preferably being a replaceable one has annular section or covering made of a low-wear material.

Eine weitere bevorzugte Ausführungsform der Erfindung kennzeichnet sich durch einen Antrieb aus zwei Motoren, die beiderseits der Mischkammer(n) angeordnet sind. Dies vergleichmäßigt die Gewichtsverteilung der Vorrichtung und erhöht damit ihre Standfestigkeit.Another preferred embodiment of the invention is characterized by a drive comprising two motors which are arranged on both sides of the mixing chamber (s). This balances the weight distribution of the device and thus increases its stability.

Die Standfestigkeit ist überhaupt ein wesentlicher und grundsätzlicher Vorteil der erfindungsgemäßen Vorrichtung, die nämlich aufgrund ihrer angegebenen Baumerkmale einen tiefliegendenSdwerpunkt und eine verhältnismäßig große Aufstandsfläche erhält.Stability is an essential and fundamental advantage of the device according to the invention, which, because of its construction characteristics, has a low center of gravity and a relatively large contact area.

Dies erlaubt auch, auf Lenkrollen zu verzichten. Die Rollen können starr angeordnet sein; die Vorrichtung kann dank ihrer Standsicherheit angekippt werden, wenn sie beim Fahren nach rechts oder links gelenkt werden soll.This also makes it possible to dispense with castors. The roles can be rigid; thanks to its stability, the device can be tilted if it is to be steered to the right or left when driving.

Eine Haube 1, die zugleich tragender Maschinenrahmen ist, hat eine_quadratische Grundfläche 2 und einen kreisförmigen oberen Rand 3, zu dem hin sie sich von der Grundfläche aus verjüngt.A hood 1, which is also a supporting machine frame, has a square base 2 and a circular upper edge 3, towards which it tapers from the base.

In spiegelsymmetrischer Gestaltung zu der Haube 1 ist auf dem Rand 3 ein oberes Trichterteil 5 angeordnet. Es ist durch eine leicht lösbare Flanschverbindung 6 an der Haube 1 befestigt.An upper funnel part 5 is arranged on the edge 3 in a mirror-symmetrical design to the hood 1. It is attached to the hood 1 by an easily detachable flange connection 6.

Die Vorrichtung hat damit im ganzen X-Form. Sie ist auf Rollen 7, deren Achsen starr an der Haube 1 angebracht sind, verfahrbar.The device is thus in the whole X shape. It can be moved on rollers 7, the axes of which are rigidly attached to the hood 1.

In der Haube ist als Fortsetzung des oberen Trichterteils 5 ein unteres Trichterteil 8 angeordnet, daß sich vom oberen Rand 3 der Haube aus, an dem es sitzt, nach unten erstreckt. An seinem unteren Ende geht es über in eine zylindrische senkrechte Mischkammer 9. An diese ist unten eine gleichfalls zylindrische waagerechte Mischkammer 10 von gleichem Durchmesser angesetzt; deren Stirnwand 11 fluchtet mit einer Mantellinie 12 der Mischkammer 9. Auf die waagerechte Mischkammer 10 folgt eine an deren Ende axial angesetzte Exzenterschneckenpumpe 13 mit einem Schlauchanschluß 14 am Ende. Die Mischkammer 10 ist über ein an ihrer Stirnwand 11 sitzendes Zwischenstück 15 an einem in die Haube 1 eingespeisten Halterahmen 16 befestigt und an ihrem Ende in einer nicht gezeichneten Weise noch einmal abgestützt.As a continuation of the upper funnel part 5, a lower funnel part 8 is arranged in the hood, which extends downward from the upper edge 3 of the hood on which it is seated. At its lower end there is a cylindrical vertical mixing chamber 9. At the bottom there is an equally cylindrical horizontal mixing chamber 10 of the same diameter; the end wall 11 is aligned with a surface line 12 of the mixing chamber 9. The horizontal mixing chamber 10 is followed by an eccentric screw pump 13 which is axially attached to the end thereof and has a hose connection 14 at the end. The mixing chamber 10 is fastened via an intermediate piece 15 seated on its end wall 11 to a holding frame 16 fed into the hood 1 and is supported again at its end in a manner not shown.

Beiderseits der senkrechten Mischkammer 9 sind mit waagerechter Achse zwei Elektromotoren 17 an dem Halterahmen 16 befestigt. Sie sind mittels eines gemeinsamen Riementriebs 18 mit einer Riemenscheibe 19 gekoppelt (Fig. 2). Diese treibt über eine Abtriebsscheibe 20 und einen weiteren Riemen 21 eine auf einer nicht gezeichneten Welle, die durch die Stirnwand 11 der Mischkammer 10 geführt ist, sitzende Antriebsscheibe 22.On both sides of the vertical mixing chamber 9, two electric motors 17 are attached to the holding frame 16 with a horizontal axis. They are coupled to a pulley 19 by means of a common belt drive 18 (FIG. 2). This drives, via a driven pulley 20 and a further belt 21, a drive pulley 22 seated on a shaft, not shown, which is guided through the end wall 11 of the mixing chamber 10.

Die genannte Welleträgt in der Mischkammer 10 eine an deren Stirnwand 11 angeordnete Zahnscheibe 24 und endet unmittelbar anschließend in einem Steckkopplungsteil 25.Said shaft e carries in the mixing chamber 10 a toothed disk 24 arranged on its end wall 11 and ends immediately afterwards in a plug-in coupling part 25.

In dieses ist ein in der Mischkammer 10 sich erstreckendes Mischwerkzeug 26 mit einer Welle 27 eingesteckt, deren Ende über eine Steckkupplung 28 mit der Schnecke 29 der Exzenterschneckenpumpe 13 verbunden ist. Ein in der Mischkammer 9 angeordnetes Mischwerkzeug 30 weist an seinem unteren Ende einen Ring 31 und an dessen Unterseite einen in die Zahnscheibe 24 greifenden Zahnkranz 32 auf und erhält damit seinen Antrieb. Der Ring 31 läuft mit etwas Spiel entlang der Mischkammerwand um, die an dieser Stelle einen Einsatzring 33 (Fig. 3) aus einem verschleißarmen Material aufweist, z.B.A mixing tool 26, which extends in the mixing chamber 10 and has a shaft 27, is inserted into the latter, the end of which is connected to the screw 29 of the eccentric screw pump 13 via a plug-in coupling 28. A mixing tool 30 arranged in the mixing chamber 9 has a ring 31 at its lower end and a toothed ring 32 which engages in the toothed disc 24 on its underside and thus receives its drive. The ring 31 runs with some play along the mixing chamber wall, which at this point has an insert ring 33 (FIG. 3) made of a low-wear material, for example

von dem Ring 31 erstrecken sich, beispielsweise drei oder vier, Stege 34 in geringem Abstand von der Mischkammerwandung nach oben. An ihrem oberen Ende sind sie durch Speichen 35 mit einer axialen Stange 36 verbunden, über die das Mischwerkzeug 30 in einem Lager 37 aufgehängt ist, das in dem Trichterteil 5 von Speichen 38 gehalten ist. Ein auf dem Mischwerkzeug 30 angeordnetes Lockerungswerkzeug 39 streicht in dem unteren Trichterteil 8 an dessen Wandung entlang.from the ring 31, for example three or four webs 34 extend at a short distance from the mixing chamber wall upwards. At their upper end they are connected by spokes 35 to an axial rod 36, via which the mixing tool 30 is suspended in a bearing 37, which is held in the funnel part 5 by spokes 38. A loosening tool 39 arranged on the mixing tool 30 sweeps along the wall of the lower funnel part 8.

An der einen Seite der Vorrichtung ist ein Schaltkasten 40 mit den Schaltarmaturen für die Bedienung der Vorrichtung angebracht. Im übrigen befinden sich alle elektrischen und mechanischen Teile unter der Haube 1.On one side of the device there is a switch box 40 with the switch fittings for operating the device. In addition, all electrical and mechanical parts are located under the hood 1.

Aus dem mit Baustoff, wie Trockenmörtel, gefüllten Trichter rutscht das Material stetig nach unten in die Mischkammer 9. Das Lockerungswerkzeug 39 verhindert dabei die Bildung von Materialbrücken im unteren Bereich des Trichters.From the funnel filled with building material, such as dry mortar, the material slides down continuously into the mixing chamber 9. The loosening tool 39 prevents the formation of material bridges in the lower region of the funnel.

In der Mischkammer 9 tritt durch eine Wassereinführung 23 eingeleitetes Masse! in dosierter Menge hinzu. Die Wassereinführung 23 ist leicht nach unten und leicht tangential angestellt und gibt damit dem einströmenden Wasserstrahl eine die Durchmischung und die Materialförderung nach unten unterstützende Ausrichtung. Das Mischwerkzeug 30 mischt und hält die Wandung der Mischkammer frei von Ansatz. Gleiches gilt für das Mischwerkzeug 26 in der nachfolgenden waagerechten Mischkammer 10. Die Pumpe 13 zieht die fertige Baustoff-Wasser-Mischung aus den Mischkammern ab und drückt sie, wobei sie noch einmal eine Mischwirkung ausübt, durch den Schlauchanschluß 14 ab.Mass introduced in the mixing chamber 9 passes through a water inlet 23! in a metered amount. The water inlet 23 is set slightly downwards and slightly tangentially and thus gives the incoming water jet an orientation which supports the mixing and the material conveyance downwards. The mixing tool 30 mixes and keeps the wall of the mixing chamber free of deposits. The same applies to the mixing tool 26 in the subsequent horizontal mixing chamber 10. The pump 13 draws the finished building material-water mixture out of the mixing chambers and presses it through the hose connection 14, again exerting a mixing effect.

Die Vorrichtung kann mit etwa 70 cm die niedrigste für dergleichen Mischvorrichtungen bekannte Bauhöhe aufweisen. Sie läßt sich damit nicht nur besonders leicht mit Sackware füllen, sondern sogar als Ganzes unter den Auslauf eines üblichen Baustellencontainers schieben. Es ist auch möglich, sie so auszugestalten, daß sie nach Abnehmen des oberen Trichterteils 5 unmittelbar an den Auslauf eines Containers angeflanscht werden kann. Das Gewicht ist gering, zumal im Gegensatz zu anderen Vorrichtungen keinerlei Drehmoment über die Trichterwandung übertragen wird und diese daher entsprechend leicht gehalten werden kann.At approximately 70 cm, the device can have the lowest overall height known for such mixing devices. It is not only particularly easy to fill with bagged goods, but can even be pushed as a whole under the outlet of a conventional construction site container. It is also possible to design it so that it can be flanged directly to the outlet of a container after removing the upper funnel part 5. The weight is low, especially since, in contrast to other devices, no torque is transmitted via the funnel wall and this can therefore be kept correspondingly light.
