Abstract

The invention is directed to a method of and a system for mixing batches of a flowable medium, especially of hydrocarbons used as base materials for said media and of additives to be admixed thereto. In the mixing operation, the base materials and optionally additives are weighed in a primary weighing section capable of holding a complete batch to form the base medium. Independently thereof, additives, amounting to minor fractions of the batch, are weighed out in at least one precision weighing section. The weighed-out additive fractions are then admixed to the weighed-out base medium.

Description

Die Erfindung bezieht sich auf ein Verfahren zum Mischen von Partien eines fließfähigen Mediums, insbesondere von als Grundstoffe für die Medien dienenden fließfähigen Koh­lenwasserstoffen und Additiven, die diesen beizumischen sind, und eine Vorrichtung zur Durchführung dieses Ver­fahrens.The invention relates to a method for mixing batches of a flowable medium, in particular flowable hydrocarbons and additives serving as raw materials for the media, which are to be mixed with them, and an apparatus for carrying out this method.

Es sind vollautomatische Mischanlagen für Öle und diesen Ölen beizumischende Additive bekannt. Diese Mischanlagen haben eine Wägevorrichtung, deren Behälter jeweils eine vollständige Partie aufnehmen kann. In diesen Wägebehälter werden nacheinander die Öle und Additive eingewogen. Das Beimischen von kleinen Additivmengen, die in der Größenordnung von Bruchteilen der vollständigen Partie liegen, erfolgt dabei recht un­genau. Wägevorrichtungen dieser Art wiegen beispielsweise bis zu 50 t des betreffenden Mediums aus. Das Beiwiegen von Bruchteilen, beispielsweise 200 g eines Additivs, läßt sich in dieser Wägevorrichtung nur außerordentlich grob vornehmen.Fully automatic mixing systems for oils and additives to be added to these oils are known. These mixing plants have a weighing device, the container of which can hold a complete batch. The oils and additives are weighed one after the other into this weighing container. The admixture of small amounts of additives, which are of the order of fractions of the complete batch, is quite imprecise. Weighing devices of this type weigh, for example, up to 50 t of the medium in question. Weighing in fractions, for example 200 g of an additive, can only be carried out extremely roughly in this weighing device.

Es ist auch bekannt, Wägevorrichtungen mit einem Behälter­fassungsvermögen von 800 bis 1000 kg einzusetzen. Diese Wägevorrichtungen können zwar Bruchteile der Partie ein­wiegen; Partiebruchteile in der Größenordnung von 200 g der beizumischenden Komponenten können aber auch dabei nur schwierig ausgewogen werden. Diese bekannten Wägevorrich­tungen mit Wägebehältern für 800 bis 1000 kg lassen sich mobil anordnen, und die Wägebehälter werden dann zu einem Tankwagen oder Großtank verfahren bzw. ihr Inhalt wird in größere Aufbewahrungs- oder Transportbehälter übergelei­tet. Diese Vorgänge wiederholen sich, bis genügend fertige Mischung erzeugt wurde.It is also known to use weighing devices with a container capacity of 800 to 1000 kg. These weighing devices can weigh a fraction of the batch; Batch fractions of the order of 200 g of the components to be mixed in can also be weighed out only with difficulty. These known weighing devices with weighing containers for 800 to 1000 kg can be arranged in a mobile manner, and the weighing containers then become one Move tankers or large tanks or their contents are transferred to larger storage or transport containers. These processes are repeated until a sufficient finished mixture has been produced.

Der Trend beim Mischen von Grundstoffen und deren Kompo­nenten bzw. Additiven geht dahin, mehr Additive in feiner ausgewogenen Dosen einem Grundstoff beizumischen.The trend in the mixing of raw materials and their components or additives is towards adding more additives in finely balanced cans to a raw material.

Es ist Aufgabe der Erfindung, ein Verfahren und eine Vor­richtung zum Auswiegen von flüssigen Medien zu schaffen, bei dem auch die kleinen, nur in Bruchteilen einer voll­ständigen Partie beizumischenden Additive in großer An­zahl und genau abwiegbaren Mengenanteilen bereitgestellt werden können.It is an object of the invention to provide a method and a device for weighing liquid media, in which even the small additives which are to be mixed in only a fraction of a complete batch can be provided in large numbers and precisely weighable proportions.

Die gestellte Aufgabe ist dadurch gelöst, daß in einen Haupt-Wägevorrichtungsteil mit einem Fassungsvermögen ei­ner vollständigen Partie Grundstoffe und gegebenenfalls Additive als Basismedium eingewogen, daß unabhängig davon in wenigstens einem Fein-Wägevorrichtungsteil Additive in der Größenordnung von Bruchteilen der Partie ausgewogen werden und daß die ausgewogenen Additivbruchteile dem aus­gewogenen Basismedium beigemischt werden.The object is achieved in that in a main weighing device part with a capacity of a complete batch of raw materials and optionally additives as a basic medium, that independently in at least one fine weighing device part additives are weighed in the order of fractions of the lot and that the balanced Additive fractions are added to the balanced base medium.

In dem Haupt-Wägebehältnis der Haupt-Wägevorrichtung wer­den die größeren Partieanteile, vor allen Dingen die Grund­stoffe ausgewogen. Der Haupt-Wägevorrichtungsteil ist nur in der Lage, Grobwägungen vorzunehmen. Für die großen An­teile des Basismediums ist dies auch ausreichend genau. In dem Fein-Wägevorrichtungsteil wird dann ein Feinaus­wiegen der Additive vorgenommen, die der Partie nur in der Größenordnung von Bruchteilen beigefügt werden. Nach dem Auswiegen der Bruchteile der Additive werden diese in das Basismedium eingeführt, dort jedoch wird nur die Summe ausgewogen. Das Signal der Auswage dient dem Rechner als Erfüllungsmeldung für die vollständige Entleerung des mobilen Wägebehälters.In the main weighing container of the main weighing device, the larger batches, especially the basic materials, are weighed out. The main weighing device part is only able to carry out rough weighing. This is also sufficiently precise for the large proportions of the basic medium. In the fine weighing device part, the additives are then weighed out, which are only added to the batch in the order of fractions. After the fractions of the additives are weighed out, they are added to the Basic medium introduced, but only the sum is balanced there. The signal from the weigher serves as a notification of fulfillment for the complete emptying of the mobile weighing container.

Eine Vorrichtung zur Durchführung dieses Verfahrens ist gekennzeichnet durch ein Haupt-Wägevorrichtungsteil mit einem Haupt-Wägebehältnis für eine vollständige Partie und wenigstens einem Fein-Wägevorrichtungsteil mit einem Fein-­Wägebehältnis der Additivteile der Partie, wobei das Fein-­Wägebehältnis der Additivteile zum Haupt-Wägebehältnis überführbar und eine Flüssigkeits-Überleitvorrichtung vor­gesehen ist, mit der eine Überleitverbindung von Fein-Wä­gebehältnis der Additivteile zum Haupt-Wägebehältnis der vollständigen Partie herstellbar ist.An apparatus for performing this method is characterized by a main weighing device part with a main weighing container for a complete batch and at least one fine weighing device part with a fine weighing container of the additive parts of the batch, the fine weighing container of the additive parts being convertible to the main weighing container and a liquid transfer device is provided with which a transfer connection from the fine weighing container of the additive parts to the main weighing container of the complete batch can be produced.

Nach einer weiteren Ausgestaltung der Erfindung ist vorge­sehen, daß die Fein-Wägevorrichtung Ziffernschritte von 10 bis 20 g aufweist bei einer Höchstlast von 5 bis 200 kg. Derartig feine Beimessungsschritte reichen auch für kleine Mengen der Additive aus.According to a further embodiment of the invention, it is provided that the fine weighing device has numerical steps of 10 to 20 g at a maximum load of 5 to 200 kg. Such fine metering steps are sufficient even for small amounts of the additives.

Zum Überführen des Fein-Wägebehältnisses zum Haupt-Wägebehält­nis ist nach einer weiteren Ausgestaltung der Erfindung vorgesehen, daß das Fein-Wägebehältnis der Additivteile auf einer Überführstraße mittels eines Wagens verfahrbar ist.To transfer the fine weighing container to the main weighing container, it is provided according to a further embodiment of the invention that the fine weighing container of the additive parts can be moved on a transfer line by means of a trolley.

Die Fein-Wägebehältnisse haben eine kleinere Öffnungsweite als die Haupt-Wägebehältnisse. Dadurch ist die Zahl der Einleitventile für Additive bei den Fein-Wägebehältnissen beschränkt. Da jedoch eine große Anzahl von Additiven aus­gewogen und verarbeitet werden muß, werden mehrere Fein-­Wägevorrichtungsteile mit Fein-Wägebehältnissen eingesetzt.The fine weighing containers have a smaller opening width than the main weighing containers. This limits the number of feed valves for additives in the fine weighing containers. However, since a large number of additives have to be weighed and processed, several fine weighing device parts with fine weighing containers are used.

Nach einer weiteren Ausgestaltung der Erfindung ist dann vorgesehen, daß bei mehreren Fein-Wägevorrichtungsteilen für Additivteile die Überführstraße parallel zu der Reihe dieser Fein-Wägevorrichtungsteile verläuft.According to a further embodiment of the invention, it is then provided that in the case of several fine weighing device parts for additive parts, the transfer line runs parallel to the row of these fine weighing device parts.

Um mehrere Partien gleichzeitig anfertigen zu können, ist nach einer weiteren Ausgestaltung der Erfindung vorgesehen, daß parallel zur Überführstraße mehrere Haupt-Wägevorrich­tungen angeordnet sind. Das Überführen der Fein-Wägebehält­nisse zu den Haupt-Wägebehältnissen kann dann mit Hilfe des Wagens ohne Schwierigkeiten vorgenommen werden.In order to be able to produce several batches at the same time, according to a further embodiment of the invention it is provided that several main weighing devices are arranged parallel to the transfer line. The transfer of the fine weighing containers to the main weighing containers can then be carried out with the help of the trolley without difficulty.

Nach einer weiteren Ausgestaltung der Erfindung ist vorge­sehen, daß zwischen jedem Haupt-Wägevorrichtungsteil und der Überführstraße Hebevorrichtungen für Wägebehältnisse der Additivteile vorgesehen sind. Dabei ist es möglich, daß die Hebevorrichtungen mit zusätzlichen Mischvorrichtungen versehen sind. In diesem Zusammenhang ist es auch möglich, daß seitlich der Überführstraße Parkstationen vorgesehen sind.According to a further embodiment of the invention, it is provided that lifting devices for weighing containers of the additive parts are provided between each main weighing device part and the transfer line. It is possible that the lifting devices are provided with additional mixing devices. In this context, it is also possible that parking stations are provided on the side of the transfer road.

Schließlich ist vorgesehen, daß die Haupt-Wägevorrichtungs­teile eine Höchstbelastung von 15 t aufweisen. Eine derar­tige Auslegung der Höchstbelastung hat den Vorteil, daß die einzelnen Partien in der Größenordnung des Fassungsvermö­gens von Tankwagen liegen. Ein Tankwagen kann dann entweder mit einer Partie oder mit zwei Partien beladen werden.Finally, it is provided that the main weighing device parts have a maximum load of 15 t. Such an interpretation of the maximum load has the advantage that the individual batches are in the order of magnitude of the capacity of tankers. A tank truck can then be loaded with either one lot or two lots.

Die Erfindung wird anhand der Zeichnung näher erläutert. Es zeigen:

  • Fig. 1 eine Draufsicht auf eine Vorrichtung zur Durch­führung von Hauptwägungen und Feinwägungen zum Zusammenstellen eines ausgewogenen Gemisches aus einem Basismedium und zugefügten Additiven in feinen Dosierungen;
  • Fig. 2 die Vorrichtung nach Fig. 1 in Seitenansicht.
The invention is explained in more detail with reference to the drawing. Show it:
  • Figure 1 is a plan view of a device for carrying out main weighing and fine weighing to put together a balanced mixture of a base medium and added additives in fine doses.
  • Fig. 2 shows the device of FIG. 1 in side view.

In Fig. 1 sind nebeneinander in Reihe drei Haupt-Wägevor­richtungsteile 1 dargestellt. Wie Fig. 2 zeigt, bestehen die Haupt-Wägevorrichtungsteile 1 jeweils aus einem Haupt-­ Wägebehältnis 3 und aus einer Hauptwaage 5. Die Haupt-Wä­gebehältnisse 3 haben beispielsweise ein Fassungsvermögen von 15 t. In diese Haupt-Wägebehältnisse sind aus einer Anzahl von nicht dargestellten Vorratsbehältern über Ver­bindungsleitungen und nur schematisch dargestellte Aus­laßventile 7 Anteile eines zu mischenden Mediums, bei­spielsweise eines als Grundstoff dienenden Kohlenwasser­stoffes, einleitbar. Die Hauptwaage 5 läßt nur Grobwägun­gen bis zu Minimalschritten von etwa 100 g zu. Für größe­re Dosiermengen ist die Zumessung in derart groben Schritt­mengen möglich. Für kleinere Additivbeigaben, die nur in Bruchteilen einer vollständigen Partie zugegeben werden, genügen derart grobe Meßschritte nicht.In Fig. 1 three main weighing device parts 1 are shown side by side in a row. As shown in FIG. 2, the main weighing device parts 1 each consist of a main Weighing container 3 and from a main scale 5. The main weighing containers 3 have, for example, a capacity of 15 t. Parts of a medium to be mixed, for example a hydrocarbon serving as the base material, can be introduced into these main weighing containers from a number of storage containers (not shown) via connecting lines and only schematically illustrated outlet valves. The main scale 5 only allows rough weighing up to minimal increments of approximately 100 g. For larger dosing quantities, metering in such coarse increments is possible. Such coarse measuring steps are not sufficient for smaller additives which are only added in fractions of a complete batch.

Für das Feinauswiegen von kleinen Additivmengen sind vier weitere Fein-Wägevorrichtungsteile 9 vorgesehen. Auch diese Fein-Wägevorrichtungsteile sind in einer Reihe an­geordnet. Die Reihen aus den beiden Vorrichtungsteilen 1 und 3 liegen parallel zueinander. Die Fein-Wägevorrich­tungsteile 9 bestehen ihrerseits wieder aus Fein-Wägebe­hältnissen 11 und Feinwaagen 13. Die Fein-Wägevorrichtungs­teile 9 sind zum Auswiegen von Additivanteilen zwischen 5 und 200 kg ausgelegt. Die Feinwaage 13 ist in der Lage, in Ziffernschritten von 10 bis 20 g auszuwiegen.Four further fine weighing device parts 9 are provided for the fine weighing of small amounts of additives. These fine weighing device parts are also arranged in a row. The rows from the two device parts 1 and 3 are parallel to each other. The fine weighing device parts 9 in turn consist of fine weighing containers 11 and fine scales 13. The fine weighing device parts 9 are designed for weighing additive components between 5 and 200 kg. The fine scale 13 is capable of weighing in increments of 10 to 20 g.

Zwischen den in Reihen angeordneten Wäge-Vorrichtungstei­len 1 und 9 befindet sich eine Überführstraße 15. Auf die­ser Überführstraße 15 ist ein Wagen 17 verfahrbar. Zwi­schen der Überführstraße 15 und den Haupt-Wägevorrich­tungsteilen 1 sind Hebevorrichtungen 19 vorgesehen. Die Hebevorrichtungen können gleichzeitig auch mit Mischvor­richtungen kombiniert sein. Weiterhin sind auch sogenannte Parkpositionen 21 beiderseits der Überführstraße 15 vorge­sehen.A transfer line 15 is located between the weighing device parts 1 and 9 arranged in rows. A carriage 17 can be moved on this transfer line 15. Lifting devices 19 are provided between the transfer line 15 and the main weighing device parts 1. The lifting devices can also be combined with mixing devices at the same time. So-called parking positions 21 are also provided on both sides of the transfer road 15.

Die einzelnen Fein-Wägebehältnisse sind mit einer Flüssig­keits-Überleitvorrichtung 23 versehen, in der sich ein Ventil 25 befindet.The individual fine weighing containers are provided with a liquid transfer device 23 in which a valve 25 is located.

Alle Wiegeergebnisse der Hauptwaagen 5 und der Feinwaagen 13 werden elektrisch erfaßt und einer Rechenanlage zugeführt. Ebenso werden Ein­laßventile 27, die sich sowohl bei den Einlässen 7 als auch bei ent­sprechenden Einlässen 29 oberhalb der Fein-Wägebehältnisse 11 befinden, elektrisch von dem Rechner bedient. Gleichzeitig mit dem Öffnen der Ab­laßhähne wird die Behälterwand elektrisch beheizt, um so die Viskosität herabzusetzen und ein schnelles Entleeren zu ermöglichen.All weighing results of the main scales 5 and the fine scales 13 are recorded electrically and fed to a computer system. Likewise, inlet valves 27, which are located both at the inlets 7 and at the corresponding inlets 29 above the fine weighing containers 11, are operated electrically by the computer. Simultaneously with the opening of the drain cocks, the container wall is electrically heated in order to reduce the viscosity and enable quick emptying.

Die Herstellung einer vollständigen Partie eines vorbe­stimmten Mediums,das aus Grundstoffen und einer Anzahl von Additiven in kleinen Mengen besteht, geht wie folgt vor sich, wobei nur ein Haupt-Wägevorrichtungsteil betrachtet wird. In diesen einen Haupt-Wägevorrichtungsteil werden beim Öffnen einzelner Ventile 27 nach Maßgabe des Rech­ners nacheinander einzelne Bestandteile der Partie einge­wogen. Es handelt sich dabei um Bestandteile, die in grö­ßeren Mengen zum Einsatz kommen. Gleichzeitig werden in einem oder mehreren Fein-Wägeteilen 9 auf entsprechende Weise nacheinander kleine Anteile von Additiven eingewo­gen. Ist das Einwiegeverfahren bei einem Fein-Wägebehält­nis abgeschlossen, dann wird dies mittels des Wagens 17 zu der Hebevorrichtung 19 des Haupt-Wägevorrichtungsteiles 1 gefahren und dort in eine Höhe gehoben, wo der Inhalt die­ses Fein-Wägebehältnisses 11 durch Öffnen des Ventiles 25 in das Haupt-Wägebehältnis 5 eingeleitet werden kann. Vor dem Einleiten kann mit einer nicht dargestellten Mischvor­richtung der Inhalt des Fein-Wägebehältnisses 11 auch noch einmal durchmischt worden sein. Wurden für die entsprechen­de Partie auch noch in einem anderen Fein-Wägebehältnis 11 Additivanteile ausgewogen, werden nach dem Entleeren des ersten Fein-Wägebehältnisses 11 in das Haupt-Wägebehältnis 5 die Fein-Wägebehältnisse gegeneinander ausgetauscht.The production of a complete batch of a predetermined medium, which consists of raw materials and a number of additives in small quantities, proceeds as follows, with only one main weighing device part being considered. In this one main weighing device part, individual components of the batch are weighed in succession when individual valves 27 are opened, according to the computer. These are components that are used in large quantities. At the same time, small amounts of additives are successively weighed in one or more fine weighing parts 9 in a corresponding manner. If the weighing-in process is completed for a fine weighing container, then this is moved by means of the carriage 17 to the lifting device 19 of the main weighing device part 1 and raised to a height where the content of this fine weighing container 11 is opened by opening the valve 25 in the main - Weighing container 5 can be initiated. Before the introduction, the contents of the fine weighing container 11 may also have been mixed again with a mixing device (not shown). If, for the corresponding batch, 11 additive fractions have also been weighed out in another fine weighing container, the fine weighing containers are exchanged for one another after emptying the first fine weighing container 11 into the main weighing container 5.

Nach dem Einleiten aller Additive in das Haupt-Wägebehält­nis 3 und einem Durchmischen seines Inhaltes ist dann die Partie vollständig und zum Abpumpen in einen Tankwagen oder in einen Vorratsbehälter bereit.After all additives have been introduced into the main weighing container 3 and the contents have been mixed, the batch is then complete and ready for pumping out into a tanker truck or into a storage container.

Das Verfahren der einzelnen Fein-Wägebehältnisse 11 er­folgt ebenso wie die Ventilbedienung und das Auswiegen vollautomatisch durch Steuerung mittels des Rechners.The individual fine weighing containers 11 are moved, as is valve operation and weighing, fully automatically by control by means of the computer.
