The control device has a liquid level signal generator, and gives an input signal to the actuating drive for operating of the shut-off device on a liquid level signal and/or an operator command, in order to initiate or finalize fill, removal or other operating condition of a tank container (1). An independent claim is also included for a tank container with a receptacle.

Description

Die Erfindung betrifft eine Steuerung für ein Befüll-/Entnahmesystem gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a controller for a filling / removal system according to the preamble of claim 1.

Tankcontainer sind Transportsysteme zum Transport fließfähiger Medien (Flüssigkeiten, druckverflüssigte Gase, Schüttgüter), welche im intermodalen Verkehr (Schiene, Straße, See) eingesetzt werden. Üblicherweise weisen Tankcontainer ein Befüll-/Entnahmesystem auf, welches aus mehreren im Behälter des Tankcontainers angebrachten Anschlüssen/Öffnungen gebildet wird. Die Anschlüsse weisen dazu in der Regel manuell betätigbare Absperreinrichtungen (Hähne, Klappen, Kugelventile etc.) auf, die zum Befüllen und Entleeren des Behälters wahlweise geöffnet oder geschlossen werden. Die Anschlüsse sind dabei teilweise unter oder über dem Flüssigkeitsspiegel im Behälter angeordnet. Der Tankcontainer wird über eine Förderpumpe bzw. über die Schwerkraft befüllt oder entleert.Tank containers are transport systems for the transport of fluid media (liquids, pressure-liquefied gases, bulk materials), which are used in intermodal transport (rail, road, sea). Usually tank containers have a filling / removal system, which is formed of several mounted in the tank container terminals / openings. The connections usually have manually operable shut-off devices (taps, flaps, ball valves, etc.) which are either opened or closed to fill and empty the container. The connections are partially arranged below or above the liquid level in the container. The tank container is filled or emptied via a feed pump or gravity.

Der Füll- oder Entnahmevorgang wird von einer Bedienperson kontrolliert. Dazu liest sie einen Peilstab ab, der in eine Mannlochöffnung hineingehalten wird und der entsprechend dem Füllgrad des Behälters angeordnete Markierungen aufweist. Dazu muß eine Bedienperson in der Regel auf den Tankcontainer steigen. Bei besonders gefährlichen Ladegütern (brennbar, giftig, ätzend) ist diese Art der Füllstandsüberwachung oft nicht möglich bzw. unerwünscht. Bei einem anderen üblichen Verfahren wird der Füllstand durch Wiegen des zu befüllenden oder zu entleerenden Tankcontainers ermittelt. Dazu muß der Tankcontainer ggf. zusammen mit einem Trägerfahrzeug (LKW-Auflieger, Waggon) auf einer entsprechend geeigneten Waage angeordnet werden. Solche Schwerlastwaagen (übliche Tankcontainergewichte bewegen sich im Rahmen von 3.000 bis 36.000 kg) mit einer entsprechenden Genauigkeit sind teuer und nicht immer an den Entnahme- bzw. Füllorten verfügbar.The filling or removal process is controlled by an operator. For this purpose, it reads off a dipstick, which is held into a manhole opening and which has markings arranged in accordance with the degree of filling of the container. For this purpose, an operator usually has to climb onto the tank container. For particularly dangerous goods (combustible, toxic, corrosive) this type of level monitoring is often not possible or undesirable. In another conventional method, the level is determined by weighing the tank container to be filled or emptied. For this purpose, the tank container may need to be arranged together with a carrier vehicle (truck semi-trailer, wagon) on a suitable scale. Such heavy duty scales (common tank container weights range from 3,000 to 36,000 kg) with a corresponding accuracy are expensive and not always available at the picking or filling locations.

Aus der DE 44 40 883 A1 als nächstliegendem Stand der Technik, ist eine Steuerung für ein Befüll-/Entnahmesystem gemäß dem Oberbegriff des Anspruchs 1 bekannt. Eine ähnliche Steuerung ist im US-Patent 6,073,081 angegeben.From the DE 44 40 883 A1 As the closest prior art, a control for a filling / removal system according to the preamble of claim 1 is known. A similar control is in the U.S. Patent 6,073,081 specified.

Davon ausgehend besteht die Aufgabe, eine verbesserte Steuerung für ein Befüll-/Entnahmesystem eines Tankcontainers bereitzustellen, die einfach bedienbar und sicher einen Entnahme- oder einen Befüllzustand bzw. einen anderen Betriebszustand (z.B. Reinigen) eines Tankcontainers steuert.Based on this, the object is to provide an improved control for a tank container filling / removal system, which simply and safely controls a removal or filling state or another operating state (for example cleaning) of a tank container.

Diese Aufgabe wird dadurch gelöst, daß eine Steuerungseinrichtung vorgesehen ist, die einen Füllstandssignalgeber umfaßt und auf ein Füllstandssignal.und/oder ein Bedienerkommando hin ein Stellsignal an einen Stellantrieb zum Betätigen der am Hauptanschluß vorgesehenen Absperreinrichtung gibt, um einen Befüll-, einen Entnahme- oder einen anderen Betriebszustand einzuleiten oder zu beenden. Zum Befüllen bzw. zum Entleeren wird der HauptanschluiS an eine Füll- bzw. Entleerleitung angeschlossen, auf ein Bedienerkommando hin gibt die Steuerungseinrichtung ein Stellsignal an den Stellantrieb zum Öffnen der Absperreinrichtung. Der Füllvorgang wird gestartet. Bei Erreichen des gewünschten Füllgrades gibt der F'üllstandssignalgeber ein Füllstandssignal an die Steuerungseinrichtung, welche daraufhin ein Stellsignal an den Stellantrieb zum Schließen der Absperreinrichtung gibt. Wahlweise ist es auch möglich, den Füllvorgang durch ein entsprechendes Bedienerkommando zu beenden. Eine manuelle Betätigung der Absperreinrichtung selbst ist nicht erforderlich. Dabei wird der Betriebszustand einer weiteren Absperreinrichtung am Hauptanschluß in der Steuerung berücksichtigt. Eine solche zusätzliche Absperreinrichtung ist für bestimmte, als besonders gefährlich eingestufte Ladegüter vorgeschrieben, um die Sicherheit gegen versehentliches Auslaufen von Ladegütern zu erhöhen. Durch die Berücksichtigung der Stellung dieser Absperreinrichtung in der Steuerung kann verhindert werden, daß der Befüll- bzw. Entleervorgang, aber auch der Spülvorgang gestartet wird, ohne daß diese zweite Absperreinrichtung ordnungsgemäß geöffnet ist.This object is achieved in that a control device is provided which comprises a level signal and a Füllstandssssignal.und / or an operator command out a control signal to an actuator for actuating the provided on the main shut-off device to a filling, a withdrawal or to initiate or terminate another operating state. For filling or emptying of HauptanschluiS is connected to a filling or emptying, in an operator command, the control device is an actuating signal to the actuator for opening the shut-off device. The filling process is started. Upon reaching the desired degree of filling the F'üllstandssignalgeber gives a level signal to the control device, which then gives an actuating signal to the actuator for closing the shut-off device. Optionally, it is also possible to end the filling process by a corresponding operator command. A manual operation of the shut-off itself is not required. In this case, the operating state of a further shut-off device is taken into account at the main terminal in the controller. Such an additional shut-off device is prescribed for certain goods classified as particularly dangerous, to increase the safety against accidental discharge of goods. By taking into account the position of this shut-off in the control can be prevented that the filling or emptying, but also the flushing process is started without this second shut-off device is properly opened.

Die Weiterbildung gemäß Anspruch 2 betrifft eine Steuerung, die geeignet ist, ein Befüll-/Entnahmesystem zu steuern, das einen hermetisch abgeschlossen Füll-/Entnahmevorgang ermöglicht. Eine solche hermetische Befüllung bzw. Entleerung ist bei solchen Ladegütern erforderlich, die nicht der Atmosphäre ausgesetzt werden dürfen bzw. nicht an die Atmosphäre gelangen dürfen. Insbesondere wird diese Art der Befüllung/Entleerung bei unter Druck verflüssigten Gasen angewendet. Dazu muß neben dem als sog. Flüssigphase ausgebildeten Hauptanschluß ein weiterer als sog. Gasphase ausgebildeter Hilfsanschluß mit den entsprechenden Absperreinrichtungen angesteuert werden. Ein solches Befüll-/Entnahmesystem wird auch als Gaspendelung bezeichnet. Die Steuerung ist dabei so eingerichtet, daß die Steuerungseinrichtung auf das Füllstandssignal bzw. ein Bedienerkommando hin sowohl den ersten Stellantrieb an der ersten Absperreinrichtung und einen zweiten Stellantrieb an der zweiten Absperreinrichtung in gewünschter Weise ansteuert (Schließen/Öffnen).The development according to claim 2 relates to a controller which is suitable to control a filling / removal system, which allows a hermetically completed filling / removal process. Such a hermetic filling or emptying is required for such goods that must not be exposed to the atmosphere or not to the Atmosphere may come. In particular, this type of filling / emptying is applied to liquefied gases under pressure. For this purpose, in addition to the so-called. Liquid phase formed main terminal another as a so-called. Gas phase trained auxiliary terminal must be controlled with the appropriate shut-off devices. Such a filling / removal system is also referred to as gas oscillation. The controller is set up in such a way that the control device, in response to the fill level signal or an operator command, activates both the first actuator on the first shut-off device and a second actuator on the second shut-off device in the desired manner (closing / opening).

Gemäß Anspruch 3 ist es auch möglich, eine Förderpumpe in die Steuerung miteinzubinden. So kann verhindert werden, daß weiter Ladegut gefördert wird, obwohl die Absperreinrichtung bereits geschlossen ist bzw. der Behälter vollständig entleert ist. Diese zusätzliche Ansteuerung einer Förderpumpe verhindert eine übermäßige Beanspruchung der Leitungen und Armaturen.According to claim 3, it is also possible to incorporate a feed pump in the control. Thus it can be prevented that further load is conveyed, although the shut-off device is already closed or the container is completely emptied. This additional control of a feed pump prevents excessive stress on the lines and fittings.

Nach Anspruch 4 kann ein weiterer Betriebszustand, nämlich das Reinigen bzw. Spülen von der Steuerung miterfaßt werden. Dazu wird ein zweiter Hilfsanschluß mit einer entsprechenden Absperreinrichtung und einem Stellantrieb angesteuert, der als Reinigungsanschluß ausgeführt ist. Der Reinigungsanschluß wird dazu mit einer Reinigungsmittelversorgung verbunden und die entsprechenden Absperreinrichtungen (z.B. Hauptanschluß und Reinigungsanschluß) werden auf ein Bedienkommando hin geöffnet. Durch den Reinigungsanschluß tritt Reinigungsmittel, beispielsweise über Sprühköpfe, in den Behälter des Tankcontainers und fließt durch den geöffneten Hauptanschluß wieder ab. Nach dem Reinigen werden beide Absperreinrichtungen auf ein entsprechendes Bedienerkommando hin an der Steuerungseinrichtung wieder geschlossen. Gemäß Anspruch 5 kann die Steuerung dadurch weiter verfeinert werden, indem neben dem Füllstandssignalgeber weitere Betriebszustandssignalgeber vorgesehen sind, die Betriebszustandssignale der Absperreinrichtungen (offen, geschlossen, Öffnungsgrad) bzw. die der Förderpumpe (n) an die Steuerungseinrichtung abgeben. Dadurch ist es z.B. möglich, die Steuerung so einzurichten, daß z.B. eine Förderpumpe zum Befüllen erst dann eingeschaltet werden kann, wenn durch ein entsprechendes Signal verifiziert ist, daß sich die Absperreinrichtungen in einem gewünschten Betriebszustand befinden.According to claim 4, another operating state, namely the cleaning or rinsing can be detected by the controller. For this purpose, a second auxiliary connection is controlled with a corresponding shut-off device and an actuator, which is designed as a cleaning connection. The cleaning connection is connected to a detergent supply and the corresponding shut-off devices (eg main connection and cleaning connection) are opened in response to a control command. Through the cleaning connection enters detergent, for example via spray heads, in the container of the tank container and flows through the open main terminal again.

Nachfolgend werden die Betriebszustände beschrieben, die mit der erfindungsgemäßen Steuerung ausgeführt werden können:The operating states which can be carried out with the control according to the invention are described below:

1. Befüllen mit externer Pumpe1. Filling with external pump

Die Steuerungseinheit 42 wird über den Stromanschluß 46 mit Energie versorgt und die externe Pumpe wird über den Pumpenanschluß 47 mit der Steuerungseinheit 42 verbunden. Die Anschlußkupplung 12 wird mit einer zur Pumpe führenden Füllleitung verbunden und die Anschlußkupplung 22 wird mit der Gaspendelleitung verbunden. Der Druckluftanschluß 44 wird mit der Druckluftversorgung verbunden. Der Wahlschalter 54 wird auf die Betriebsart "Befüllen" gestellt und mit dem Schlüsselschalter 53 wird der Befüllvorgang gestartet. Dabei wird über die Signalleitung 41 ein entsprechendes Steuersignal an den Stellantrieb 14 und den Stellantrieb 18 gegeben. Die Druckluftzufuhr wird freigeschaltet und die Absperrklappe 10 sowie die Absperrklappe 17 werden geöffnet. Nach dem Öffnen der Absperrklappen 10 und 17 geben die Stellanzeigen 15 und 19 ein Zustandssignal an die Steuerung 42. Wenn die Zustandssignale der Stellungsanzeigen 43 15 und 19 angeben, daß die betreffenden Absperrklappen 10 und 17 bzw. das Bodenventil 8 geöffnet sind, wird ein Signal zum Start der Pumpe über den Anschluß 47 abgegeben. Der Füllvorgang beginnt. Wenn der Flüssigkeitsspiegel im Behälter 2 den Füllstandssignalgeber 37 erreicht, gibt dieser ein Füllstandssignal über die Leitung 41 an die Steuerung 42, die auf dieses Signal hin entsprechende Steuerungssignale an die Stellantriebe 18 und 14 zum Schließen der Absperrklappen 10 und 17 gibt sowie ein entsprechendes Signal an die Pumpe zum Unterbrechen der Förderung. Der Füllvorgang kann ebenfalls durch die Betätigung des Not-Aus-Tasters 55 unterbrochen werden. Die Betätigung des Not-Aus-Tasters 55 bewirkt, daß alle angesteuerten Absperrklappen 10 und 17 sich schließen.The control unit 42 is supplied with power via the power connection 46 and the external pump is connected to the control unit 42 via the pump connection 47. The connection coupling 12 is connected to a filling line leading to the pump and the connection coupling 22 is connected to the gas displacement line. The compressed air connection 44 is connected to the compressed air supply. The selector switch 54 is set to the operating mode "filling" and with the key switch 53, the filling process is started. In this case, a corresponding control signal to the actuator 14 and the actuator 18 is given via the signal line 41. The compressed air supply is released and the butterfly valve 10 and the butterfly valve 17 are opened. After opening the butterfly valves 10 and 17, the position indicators 15 and 19 give a status signal to the controller 42. When the status signals of the position indicators 43 and 19 indicate that the respective butterfly valves 10 and 17 and the bottom valve 8 are opened, a signal delivered to the start of the pump via the terminal 47. The filling process begins. When the liquid level in the container 2 reaches the level signal generator 37, this gives a level signal via the line 41 to the controller 42, the control signals corresponding to this signal to the actuators 18 and 14 for closing the butterfly valves 10 and 17 and a corresponding signal the pump to interrupt the promotion. The filling process can also be interrupted by the operation of the emergency stop button 55. The operation of the Emergency stop button 55 causes all the controlled butterfly valves 10 and 17 close.

2. Entleeren mit externer Pumpe2. Drain with external pump

Das Bodenventil 8 wird geöffnet. Mit dem Schlüsselschalter 53 wird der Entleervorgang gestartet. Bei Vorliegen eines entsprechenden Signals der zum Bodenventil 8 gehörigen Stellungsanzeige 43 gibt die Steuerung 42 Steuersignale an die Stellantriebe 14 und 18 zum Öffnen der Absperrklappen 10 und 17 und gibt dann auf ein entsprechendes Stellungssignal der Stellungsanzeigen 15 und 19 ein Steuersignal an die Entleerungspumpe. Der Entleerungsvorgang kann an der Schaulaterne 13 überwacht werden und ggf. über den Not-Aus-Taster 55 beendet werden. Die Steuerung 42 gibt dann entsprechende Steuerungssignale an die Stellantriebe 14 und 18 sowie die Pumpe. Die Stellantriebe 14 und 18 schließen die Absperrklappen 10 und 17. Die externe Förderpumpe wird abgestellt. Nach dem Schließen des Bodenventils 8 erlischt die Anzeigeleuchte 57. Der Entleervorgang ist abgeschlossen.All connections 12, 22, 47, 44 and 46 are connected to the corresponding lines as in the case of filling. The selector switch 54 is switched to the operating state "emptying". The bottom valve 8 is opened. The emptying process is started with the key switch 53. In the presence of a corresponding signal to the bottom valve 8 associated position indicator 43, the controller 42 controls the actuators 14 and 18 to open the butterfly valves 10 and 17 and then outputs to a corresponding position signal of the position indicators 15 and 19, a control signal to the drain pump. The emptying process can be monitored at the sight glass 13 and, if necessary, terminated via the emergency stop button 55. The controller 42 then outputs appropriate control signals to the actuators 14 and 18 and the pump. The actuators 14 and 18 close the butterfly valves 10 and 17. The external feed pump is turned off. After closing the bottom valve 8, the indicator light 57 goes out. The emptying process is complete.

3. Reinigen/Spülen mit externer Pumpe3. Cleaning / rinsing with external pump

Die Anschlußkupplung 31 wird mit der Reinigungsmittelzufuhr bzw. der Spülleitung verbunden. Das Bodenventil 8 wird geöffnet. Der Kugelhahn 33 in der Bypass-Leitung 32 geschlossen. Über den Wahlschalter 54 wird die Betriebsart Reinigen/Spülen gewählt. Bei der Inbetriebnahme über den Schlüsselschalter 53 gibt die Steuerungseinrichtung 42 Steuersignale an die Stellantriebe 14, 18 und 25 zum Öffnen der Absperrklappen 10 und 17 sowie der Kugelhähne 24' und ein Steuersignal an die Reinigungsmittel/Spülpumpe, die über die Spülanschlüsse 23 Reinigungsmittel bzw. Spülmedium zuführt. Das Spülmedium sammelt sich in der Tanksohle und läuft über die Unten-Entlehrung 7 ab. Dämpfe können über den Gaspendelanschluß 16 entweichen. Der Spülvorgang wird über den Not-Aus-Taster 55 beendet. Die Reinigungs-Spülmittelpumpe wird über ein entsprechendes Signal abgeschaltet. Die Stellantriebe 14, 18 und 25 erhalten ein Signal zum Schließen der Absperrklappen 10, 18 und der Kugelhähne 24'.The connection coupling 31 is connected to the detergent supply or the purge line. The bottom valve 8 is opened. The ball valve 33 in the bypass line 32 is closed. Via the selector switch 54, the operating mode cleaning / rinsing is selected. When commissioning via the key switch 53, the control device 42 is control signals to the actuators 14, 18 and 25 to open the butterfly valves 10 and 17 and the ball valves 24 'and a control signal to the detergent / irrigation pump, via the Rinsing connections 23 supplies detergent or rinsing medium. The flushing medium collects in the tank bottom and drains off via the bottom discharge 7. Vapors can escape via the vapor recovery port 16. The rinsing process is ended via the emergency stop button 55. The cleaning detergent pump is switched off via a corresponding signal. The actuators 14, 18 and 25 receive a signal to close the butterfly valves 10, 18 and the ball valves 24 '.

Neben den oben beschriebenen Betriebszuständen kann die Steuerung an andere gewünschte Betriebszustände angepaßt werden. Der im Ausführungsbeispiel beschriebene Füllstandssignalgeber 37 ist als Grenzstandgeber ausgeführt, der beispielsweise auf dem Vibrationsprinzip beruht. Solche Geber können beispielsweise auch nach dem Ultraschall-Prinzip, kapazitiv, radiometrisch oder konduktiv arbeiten. Es ist auch möglich, eine ein kontinuierliches Füllstandssignal an die Steuerungseinrichtung 42 abzugeben, an der dann beispielsweise eine Entnahme- bzw. Füllmenge einstellbar sein kann.In addition to the operating conditions described above, the controller can be adapted to other desired operating conditions. The level signal generator 37 described in the exemplary embodiment is designed as a limit level sensor, which is based for example on the principle of vibration. Such donors can, for example, also work according to the ultrasound principle, capacitively, radiometrically or conductively. It is also possible to deliver a continuous level signal to the control device 42, at which then, for example, a removal or filling quantity can be adjustable.

Im Ausführungsbeispiel ist das Bodenventil 8 handbetätigt, aber erfindungsgemäß mit einer Stellanzeige 43 versehen, die optional mit der Steuerung verbunden ist. Das Bodenventil 8 kann aber auch mit einem ansteuerbaren Stellantrieb versehen werden, welcher über die Steuerungseinrichtung 42 ansteuerbar ist. Es ist auch möglich, die Steuerungseinrichtung mit einem Anschluß für einen Wegfahr-Detektor zu versehen, der dazu dient, den Befüll-, Entleerungs- oder Spülvorgang sofort zu beenden, wenn sich ein Fahrzeug, auf dem sich der Tankcontainer 1 befindet, aus der vorgesehenen Position hinaus bewegt. Mit einer solchen zusätzlichen Sicherung wird verhindert, daß Ladegut aus einem Behälter austritt, wenn die Verbindung zur Unten-Entleerung 7 abgerissen wird bzw. eine angeschlossene Pumpe weiter Medium aus einem abgerissenen Anschluß pumpt.In the exemplary embodiment, the bottom valve 8 is manually operated, but according to the invention provided with a control indicator 43, which is optionally connected to the controller. However, the bottom valve 8 can also be provided with a controllable actuator, which can be controlled via the control device 42. It is also possible to provide the control device with a connection for an immobilizer, which serves to end the filling, emptying or flushing immediately when a vehicle on which the tank container 1 is located, from the provided Position moved out. With such an additional backup prevents cargo from leaking out of a container when the connection to the bottom-emptying 7 is demolished or a connected pump continues pumping medium from a torn port.

Im Ausführungsbeispiel ist zur Überwachung des Entleerungsvorgangs ein Schauglas 13 vorgesehen. Dieses kann auch durch einen mit der Steuerungseinrichtung 42 verbundenen Durchflußmesser ersetzt werden, welcher dann zum Beispiel bei vollständiger Entleerung des Behälters ein entsprechendes Steuerungssignal zum Schließen der entsprechenden Anschlüsse veranlaßt.In the exemplary embodiment, a sight glass 13 is provided for monitoring the emptying process. This can also be done by a flowmeter connected to the control means 42 is replaced, which then causes, for example, upon complete emptying of the container, a corresponding control signal for closing the respective connections.

Neben der beschriebenen Entnahme und Befüllung über die Unten-Entleerung 7 ist es auch möglich, den Behälter über eine Steigrohranordnung zu Befüllen und/oder zu Entleeren.In addition to the described removal and filling via the bottom emptying 7, it is also possible to fill the container via a riser arrangement and / or emptying.

Es ist auch möglich, die Betätigung der Stellantriebe elektrisch vorzunehmen. Die Steuer- und Stellsignale können auch auf andere geeignete Weise zwischen Steuerungseinrichtung 42 und den entsprechenden Elementen übertragen werden (z.B. über Funk).It is also possible to make the actuation of the actuators electrically. The control and positioning signals may also be transmitted in other suitable manner between controller 42 and the corresponding elements (e.g., via radio).
