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.The invention relates to a method for mixing batches of a flowable medium, in particular flowable hydrocarbons and additives which serve as raw materials for the media.

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 into this weighing container one after the other. 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 are then moved to a tank truck or large tank 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.

Aus der US-A 4 525 071 ist es bekannt, eine grössere Anzahl von Wägebehältnisse mit ausgewogenen Material-Komponenten zu Vorratsbehältern zu erfahren mittels eines Hängebahnsystems, das in Schleifen geführt wird.From US-A 4 525 071 it is known to experience a larger number of weighing containers with balanced material components for storage containers by means of a monorail system which is guided in loops.

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.

Es ist Aufgabe der Erfindung, eine Wägevorrichtung zum Auswiegen von flüssigen Medien zu schaffen, mit der auch kleine Mengen von Additiven, die nur in Bruchteilen und in grosser Anzahl einer vollständigen grossvolumigen Partie beizumischen sind, genau abgewogen bereitgestellt und beigemischt werden können.It is an object of the invention to provide a weighing device for weighing liquid media, with which even small amounts of additives, which can only be added in fractions and in large numbers to a complete, large-volume batch, can be provided and mixed in precisely weighed.

Die gestellte Aufgabe ist erfindungsgemäss gelöst durch die folgenden Merkmale:

  • a) es ist wenigstens ein Haupt-Wägevorrichtungsteil mit einem Haupt-Wägebehältnis vorgesehen, das das Fassungsvermögen einer vollständigen Partie hat, die aus Grundstoffen und Additiven zu bilden ist, wobei die Höchstlast des Haupt-Wägevorrichtungsteiles 15 t beträgt;
  • b) es sind Fein-Wägevorrichtungsteiles vorgesehen, die zum Auswiegen von Additiven in Fein-Wägebehältnissen ausgelegt sind mit Ziffernschritten von 10 bis 20 g bei einer Höchstlast von 5 bis 200 Kg;
  • c) die Fein-Wägebehältnissse sind dem Haupt-Wägevorrichtungsteil auf einer Überführstrasse auf einer Höhe heranführbar, aus der ihr Inhalt mittels einer Überleitvorrichtung in das Haupt-Wägebehältnis einleitbar ist.
The object is achieved according to the invention by the following features:
  • a) at least one main weighing device part with a main weighing container is provided, which has the capacity of a complete batch to be formed from basic materials and additives, the maximum load of the main weighing device part being 15 t;
  • b) fine weighing device parts are provided which are designed for weighing additives in fine weighing containers with increments of 10 to 20 g at a maximum load of 5 to 200 kg;
  • c) the fine weighing containers can be brought up to the main weighing device part on a transfer line at a height from which their contents can be introduced into the main weighing container by means of a transfer device.

In dem Haupt-Wägebehältnis des Haupt-Wägevorrichtungsteils, das für 15 t ausgelegt ist, werden die grösseren Partieteile, vor allen Dingen die Grundstoffe ausgewogen. Der Haupt-Wägevorrichtungsteil ist also für Grobwägungen ausgelegt, die in der Grössenordnung des Fassungsvermögens von Tankwagen liegt. Ein Tankwagen kann dann entweder mit einer Partie oder mit zwei Partien beladen werden. Für grosse Partieteile des Basismediums ist die Grobwägung ausreichend genau.In the main weighing container of the main weighing device part, which is designed for 15 t, the larger part parts, especially the basic materials, are weighed out. The main weighing device part is therefore designed for rough weighing, which is in the order of magnitude of the capacity of tankers. A tank truck can then be loaded with either one lot or two lots. The coarse weighing is sufficiently precise for large parts of the base medium.

In den Fein-Wägevorrichtungsteilen mit Ziffernschritten von 10 bis 20 g bei einer Höchstlast von 5 bis 200 kg wird ein Feinauswiegen der Additive vorgenommen, die der Partie nur von der Grössenordnung von Bruchteilen beigefügt werden. Nach dem Auswiegen der Bruchteile der Additive werden diese mittels der Überleitvorrichtung in das Basismedium eingeführt und dort noch einmal als Summe aller Partien ausgewogen. Das Signal der Auswaage dient dem Rechner als Erfüllungsmeldung für die vollständige Entleerung der mobilen Fein-Wägebehältnisse.In the fine weighing device parts with numerical increments of 10 to 20 g at a maximum load of 5 to 200 kg, the additives are weighed out, which are only added to the batch by the order of fractions. After the fractions of the additives have been weighed out, they are introduced into the base medium by means of the transfer device and there again weighed out as the sum of all the batches. The signal from the scale serves as a notification of fulfillment for the complete emptying of the mobile fine weighing containers.

Für die Fein-Wägebehältnisse der Additivpartieteile ist, da diese vor dem Haupt-Wägevorrichtungsteil angehoben werden, eine FlüssigkeitsÜberleitungsvorrichtung vorgesehen, mit der die Additivpartieteile zum Haupt-Wägebehältnis leitbar sind.A liquid transfer device is provided for the fine weighing containers of the additive part parts, since these are raised in front of the main weighing device part, with which the additive part parts can be guided to the main weighing container.

Nach einer weiteren Ausgestaltung der Erfindung ist vorgesehen, dass dem Haupt-Vorrichtungsteil eine Hebevorrichtung zugeordnet ist, mit der die Fein-Wägebehältnisse auf eine Höhe anhebbar sind, aus der die Additive mit Gefälle in das Haupt-Wägebehältnis überleitbar sind. Dabei ist nach einer weiteren Ausgestaltung der Erfindung vorgesehen, dass die Hebevorrichtung mit zusätzlichen Mischvorrichtungen versehen ist.According to a further embodiment of the invention it is provided that the main device part is assigned a lifting device with which the fine weighing containers can be raised to a height from which the additives can be transferred with a gradient into the main weighing container. According to a further embodiment of the invention, it is provided that the lifting device is provided with additional mixing devices.

Die Fein-Wägebehältnisse der Fein-Wägevorrichtungsteile 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 of the fine weighing device parts 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.

Um mehrere Partien gleichzeitig anfertigen zu können, ist nach einer weiteren Ausgestaltung der Erfindung vorgesehen, dass seitlich der Überführstrasse zwischen mehreren Haupt-Wägevorrichtungsteilen Parkstationen vorgesehen sind, in denen Fein-Wägebehältnisse, die bereits befüllt sind, vor dem Anheben und Ausleeren in ein Haupt-Wägevorrichtungsteil auf ihren Abruf warten können. Die Erfindung wird anhand der Zeichnung näher erläutert.In order to be able to manufacture several batches at the same time, a further embodiment of the invention provides that parking stations are provided on the side of the transfer line between several main weighing device parts, in which fine weighing containers that have already been filled are can wait for retrieval before lifting and emptying into a main weighing device part. The invention is explained in more detail with reference to the drawing.

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.
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 FIG. 2 shows, the main weighing device parts 1 each consist of a main weighing container 3 and a main weighing scale 5. The main weighing containers 3 have a capacity of 15 t, for example. 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 minimum steps 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 able to weigh in increments of 10 to 20 g.

Zwischen den in Reihen angeordneten WägeVorrichtungsteilen 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. 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.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 above the fine weighing containers 11 both at the inlets 7 and at corresponding inlets 29, 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. The production of a complete batch of a predetermined medium, which consists of raw materials and a number of additives in small quantities, takes place 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 in accordance with the computer. These are components that are used in large quantities. At the same time, small amounts of additives are successively weighed out 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.
