Description

Materialaufgabebehälter für Dickstoffpumpen Material feed container for thick matter pumps
Beschreibungdescription
Die Erfindung betrifft einen Materialaufgabebehälter für Zweizylinder-Dic stoffpumpen der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The invention relates to a material feed container for two-cylinder Dic material pumps of the type specified in the preamble of claim 1.
Es sind Materialaufgabebehälter dieser Art bekannt, die eine nach oben weisende Materialzuführungsöffnung, beispielsweise für den Anschluß einer Materialzufüh¬ rungsleitung, zwei an einer Stirnwand angeordnete, mit einer Verschleißbrille umrandete Fδrderzylinderδff- nungen, einen durch die Behälterwand hindurchgreifenden Druckstutzen für den Anschluß an eine Förderleitung, eine im Behälterinneren angeordnete, mit dem Druckstut¬ zen verbundene und abwechselnd vor die Förderzylinder¬ öffnungen verschwenkbare Rohrweiche und mindestens ein an einer Seitenwand gelagertes, motorisch angetrie¬ benes Rührwerk aufweisen. Die Reinigung und Wartung derartiger Behälter erfolgt üblicherweise von oben her durch die Materialzuführungsδffnung hindurch. Abgesehen davon, daß der Aus- und Einbau der Rohrweiche über die Materialzuführungsöffnung mit Schwierigkeiten verbunden ist, ist die Materialzuführungsδffnung in solchen Fällen, in denen eine Zuführungsleitung unmit¬ telbar angeschlossen ist, nur nach Lösen dieser Leitung zugänglich. Es wurde deshalb auch schon vorgeschlagen, den Materialaufgabebehälter im Bereich des Druckstut¬ zens mit einer abnehmbaren Rückwand zu versehen. Diese Anordnung hat jedoch den Nachteil, daß im Ser¬ vice-Fall die an den Druckstutzen anschließende Fδrder- leitung abmontiert werden muß. Abgesehen davon ist die Rückwand nicht in jedem Einsatzfall von außen her erreichbar. Weiter sind auch bereits am Behälter¬ boden angeordnete, mit Klappen verschließbare Reini- gungsδffnungen bekannt, die sich jedoch wegen ihrer schweren Zugänglichkeit nicht oder nur bedingt für Wartungszwecke an der Rohrweiche oder am Rührwerk eignen.Material feed containers of this type are known which have an upward-pointing material feed opening, for example for the connection of a material feed line, two conveyor cylinder openings arranged on an end wall and surrounded by wear glasses, and a pressure connection through the container wall for connection to a feed line. have a pipe switch arranged in the interior of the container, connected to the pressure nozzle and pivotable alternately in front of the feed cylinder openings, and at least one motor-driven agitator mounted on a side wall. Such containers are usually cleaned and serviced from above through the material feed opening. Apart from the fact that the removal and installation of the pipe switch via the material feed opening is difficult, the material feed opening in those cases in which a feed line is directly connected is only accessible after this line has been disconnected. It has therefore already been proposed to provide the material feed container with a removable rear wall in the area of the pressure nozzle. However, this arrangement has the disadvantage that, in the case of service, the delivery line connected to the pressure connection must be removed. Apart from that, the rear wall is not accessible from the outside in every application. Furthermore, cleaning openings which are already arranged on the container bottom and can be closed with flaps are known, but because of their difficult accessibility they are not suitable or are only suitable to a limited extent for maintenance purposes on the pipe switch or on the agitator.
Der Erfindung liegt die Aufgabe zugrunde, einen Materi¬ alaufgabebehälter zu entwickeln, der auch bei stationä¬ rem Einbau in engen Räumen leicht zu Reinigungs-, Wartungs- und Reparaturzwecken zugänglich ist, ohne daß die Leitungen für die Materialaufgabe und für den Materialabtransport abmontiert werden müssen.The invention is based on the object of developing a material feed container which is easily accessible for cleaning, maintenance and repair purposes even in the case of stationary installation in confined spaces, without the lines for the material feed and for the material removal having to be removed .
Zur Lösung dieser Aufgabe werden die in den Patentan¬ sprüchen 1 bzw. 7 angegebenen Merkmale vorgeschlagen. Weitere vorteilhafte Ausgestaltungen und Weiterbildun¬ gen der Erfindung ergeben sich aus den Unteransprüchen.To achieve this object, the features specified in patent claims 1 and 7 are proposed. Further advantageous refinements and developments of the invention result from the subclaims.
Die Erfindung geht von dem Gedanken aus, daß mindestens eine der ggf. mit dem Rührwerk bestückten Seitenwände des Materialaufgabebehälters auch bei einer stationären Installation in engen Räumen an ihrer Außenseite rela¬ tiv frei zugänglich ist, zumal der dort vorgesehene Rührwerksmotor von Zeit zu Zeit einer Wartung bedarf. Gemäß der Erfindung wird daher vorgeschlagen, daß mindestens ein mit einem Rührwerk bestücktes Seiten- wandteil als Verschlußklappe ausgebildet ist, und daß das Rührwerk beim Öffnen der Verschlußklappe durch die betreffende Reinigungs- und Wartungsöffnung hin¬ durch aus dem Behälterinneren herausschwenkbar ist. Dadurch wird einmal das Rührwerk für Wartungszwecke völlig freigelegt. Zum anderen ist auch die Rohrweiche ohne Behinderung durch die Wartungsöffnung hindurch leicht zugänglich, und zwar ohne daß hierzu andere Behälterteile oder an den Behälter angeschlossene Fδrderleitungen abmontiert werden müßten.The invention is based on the idea that at least one of the side walls of the material feed container, optionally equipped with the agitator, is relatively freely accessible on the outside even in the case of a stationary installation in narrow spaces, especially since the agitator motor provided there is serviced from time to time requirement. According to the invention, it is therefore proposed that at least one side wall part equipped with an agitator is designed as a closure flap, and that the agitator is opened when the closure flap is opened the cleaning and maintenance opening in question can be pivoted out of the interior of the container. This will completely expose the agitator for maintenance purposes. On the other hand, the pipe switch is easily accessible through the maintenance opening without obstruction, and without having to dismantle other container parts or the conveyor lines connected to the container.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist die Verschlußklappe um eine im wesentlichen senk¬ rechte Achse am Materialaufgabebehälter verschwenk¬ bar. Zweckmäßig ist hierzu die die Wartungsδffnung enthaltende Seitenwand im wesentlich senkrecht ausge¬ richtet.According to a preferred embodiment of the invention, the closure flap can be pivoted about an essentially vertical axis on the material feed container. For this purpose, the side wall containing the maintenance opening is expediently oriented substantially vertically.
Eine weitere Verbesserung der Zugänglichkeit des Behäl¬ terinneren wird dadurch erzielt, daß die Verschlu߬ klappe über einen zusätzlichen Schwenkmechanismus mit dem Materialaufgabebehälter schwenkbar verbunden ist.A further improvement in the accessibility of the interior of the container is achieved in that the closure flap is pivotally connected to the material feed container via an additional pivoting mechanism.
Vorteilhafterweise ist auf der Außenseite der Ver¬ schlußklappe ein Hydromotor angeflanscht, dessen An¬ triebswelle durch die Klappe hindurchgreift und in dieser vorzugsweise doppelt gelagert ist und auf der dem Hydromotor gegenüberliegenden Seite das Rührwerk trägt. Das Rührwerk kann dabei als Förderschnecke ausgebildet sein, die das zu fördernde Gut im Behälter¬ inneren ständig in Richtung zu den Förderzylinder- δffnungen transportiert. Grundsätzlich ist es jedoch auch möglich, reine Paddelrührwerke zu verwenden, die ohne Fδrderwirkung nur der Auflockerung bzw. Durch¬ mischung des im Behälter befindlichen Materials dienen. Im folgenden wird die Erfindung anhand des in der Zeichnung in schematischer Weise dargestellten Ausfüh¬ rungsbeispiels naher erläutert. Es zeigenAdvantageously, a hydraulic motor is flanged onto the outside of the closure flap, the drive shaft of which extends through the flap and is preferably double-mounted in the flap and carries the agitator on the side opposite the hydraulic motor. The agitator can be designed as a screw conveyor that constantly transports the material to be conveyed inside the container towards the feed cylinder openings. In principle, however, it is also possible to use pure paddle agitators which, without the aid of a conveyor, only serve to loosen or mix the material in the container. The invention is explained in more detail below with reference to the exemplary embodiment shown schematically in the drawing. Show it

Der auf ein Fußgestell 12 montierte Materialaufgabe- behälter 10 ist Bestandteil einer Zweizylinder-Dick¬ stoffpumpe, deren Fδrderzylinder 14 über Förderzylin¬ deröffnungen 16 in der Stirnwand 18 an den Materialauf¬ gabebehälter angeschlossen sind. An der der Stirn¬ wand 18 gegenüberliegenden Rückwand 20 des Material¬ aufgabebehälters befindet sich ein Druckstutzen 22, an den die Fδrderleitung 24 der Dickstoffpumpe ange¬ schlossen ist. Im Behälterinneren befindet sich eine hier als S-Rohr ausgebildete Rohrweiche 26, die an ihrem einen Ende mit dem Druckstutzen 22 verbunden ist und deren anderes Ende abwechselnd um die Achse der Schwenkwelle 28 mit Hilfe eines Hydrozylinders vor die beiden Forderzylinderoffnungen 16 verschwenkbar ist. Die Rohrweiche 26 trägt an ihrem zylinderseitigen Ende einen Verschleißring 28, der auf einer im Bereich der Forderzylinderoffnungen 16 angeordneten Verschlei߬ brille 30 verschiebbar ist. Die Seitenwände 32 des Materialaufgabebehälters 10 enthalten eine Wartungsδff- nung 33, die durch jeweils eine am Materialaufgabe- behälter 10 angelenkte Verschlußklappe 34 verschließbar ist. Die Verschlußklappen 34 sind zu diesem Zweck über einen Schwenkmechanismus 36 mit dem Behälter 10 verbunden. An den Verschlußklappen 34 sind außerdem mittels eines Hydromotors 40 angetriebene Rührwerke 36 um eine horizontale Achse 38 drehbar gelagert. Die Rührwerke sind in dem gezeigten Ausführungsbeispiel als Förderschnecken ausgebildet, die das im Behälter 10 angeordnete dickflüssige Material durchmischen und zugleich zu den Forderzylinderoffnungen 16 hin fördern. Die Beschickung des Materialaufgabebehälters erfolgt über die Materialzuführungsδffnung 42, ggf. über einen auf den Flansch 44 aufsetzbaren Fülltrichter 46 oder über eine nicht dargestellte Materialzuführungsleitung.The material feed container 10 mounted on a pedestal 12 is part of a two-cylinder thick matter pump, the feed cylinder 14 of which is connected to the material feed container via feed cylinder openings 16 in the end wall 18. On the rear wall 20 of the material feed container opposite the end wall 18 there is a pressure connection 22 to which the delivery line 24 of the thick matter pump is connected. In the interior of the container there is a pipe diverter 26 designed here as an S-tube, which is connected at one end to the pressure connection 22 and the other end of which can be pivoted alternately about the axis of the pivot shaft 28 with the aid of a hydraulic cylinder in front of the two delivery cylinder openings 16. The pipe switch 26 has a wear ring 28 at its cylinder end, which can be displaced on a wear glasses 30 arranged in the area of the feed cylinder openings 16. The side walls 32 of the material feed container 10 contain a maintenance opening 33, which is opened by a Container 10 hinged flap 34 can be closed. For this purpose, the closure flaps 34 are connected to the container 10 via a swivel mechanism 36. Agitators 36 driven by a hydraulic motor 40 are also rotatably mounted on the closure flaps 34 about a horizontal axis 38. In the exemplary embodiment shown, the agitators are designed as screw conveyors which mix the viscous material arranged in the container 10 and at the same time convey them to the feed cylinder openings 16. The material feed container is charged via the material feed opening 42, possibly via a filling funnel 46 which can be placed on the flange 44 or via a material feed line (not shown).
Beim Öffnen der Verschlußklappe 34 wird zugleich das Rührwerk 36 durch die Öffnung 33 hindurch nach außen geklappt und kann dort ohne Schwierigkeiten gewartet werden. Dadurch werden außerdem die Rohrweiche 26 und die Verschleißteile 28 und 30 durch die Wartungs¬ öffnung 33 hindurch frei zugänglich. Durch Lösen des rückwärtigen Druckflansches 46 kann das S-Rohr 26 von der Behälterrückwand 20 entfernt und durch die Wartungsδffnung 33 hindurch ausgebaut bzw. gegen ein neues S-Rohr ausgetauscht werden. Dies gilt insbesonde¬ re, wenn das Druckstutzenlager als nach innen demon¬ tierbares Flanschlager ausgebildet und eine trennbare Schwenkwelle 28 vorgesehen ist. Die Vorteile der be¬ schriebenen Konstruktion beim Handling der relativ schweren Rohrweiσhe sind daher offensichtlich. When the flap 34 is opened, the agitator 36 is also folded out through the opening 33 and can be serviced there without difficulty. As a result, the pipe switch 26 and the wearing parts 28 and 30 are also freely accessible through the maintenance opening 33. By loosening the rear pressure flange 46, the S-tube 26 can be removed from the container rear wall 20 and removed through the maintenance opening 33 or exchanged for a new S-tube. This applies in particular if the pressure port bearing is designed as a flange bearing that can be dismantled inwards and a separable pivot shaft 28 is provided. The advantages of the described construction when handling the relatively heavy pipe size are therefore obvious.
