Definitions

  • the invention relates to a device for filling chambers of a tank vehicle via filling valves of a stationary filling plant according to claim 1.
  • Tank vehicles are known to have several chambers, and each chamber is associated with a bottom valve for liquid delivery, which is usually also Beföllventil.
  • the tank vehicles are thus attacked from below (bottom loading). Care must be taken that air or gas can escape from the assigned tank chamber. It is mandatory (VOC directive) to capture and recycle the gases. This is done via a gas return line, which is connected to the stationary filling system. Gas recirculation can be problematic because e.g. the detonation fuses in the pipeline freeze. Also on the take-off side of the filling system, there may be an impermissible pressure increase. The result is broken chamber partitions. In certain climatic conditions, avalanches can occur.
  • the invention has for its object to provide a device for infilling chambers of a tanker via filling valves of a stationary system, are avoided in the impermissible pressure increases.
  • the Kochföllommessensoren in the tank chambers is assigned a respective pressure sensor.
  • the pressure sensor provides a signal to the signal line for the overfill prevention sensors, e.g. via a switch in a line to the raid security sensor or the
  • the invention takes advantage of the fact that in the underfill filling the tank chambers are equipped with overfill protection sensors.
  • the overfill protection sensors are connected via a signal line to the control device in the stationary system and / or in the tanker. If an overfill safety sensor responds, the corresponding filling valve of the system or the bottom valve at the tank chamber is closed.
  • the overfill prevention sensors associated with a pressure sensor such as a pressure switch, which causes the control device receives a signal via the already existing signal line, thereby closing the associated filling valve.
  • the signal transmitted via the signal line is either the signal "tank full” or a fault signal, the noise being interpreted as "tank full”. This avoids further increase in pressure and thus the destruction of the tank chamber or the entire tank of the vehicle.
  • the means to be used in the invention in addition to a filling system are minimal, since only a simple pressure sensor is to be provided, which acts accordingly on the overfill sensor or the line to the overfill sensor.
  • the pressure sensor is integrated in a housing of the overfull safety sensor, wherein the pressure sensor is connected via an opening in the housing with the tank interior.
  • the overfill prevention sensor is preferably an optical sensor as widely used. Such an optical sensor operates, for example, according to the prism reflex principle, for example in the infrared range. A light beam is deflected by a prism and detected by a photocell. This state generates a release signal in the depot-side control device.
  • the prism Once the prism is immersed in liquid, the light beam is deflected and no longer reaches the photocell. As a result, the signal for switching off the filling or to close the Befullventils is given.
  • Other sensors can also be used, eg float switches, electronic dipsticks etc.
  • the pressure sensor is mechanically coupled to a switch in the overfill sensor. This can e.g. interrupt the circuit to the sensor or short-circuit it, which is detected by the controller in the gantry or tanker.
  • the pressure sensor is associated with a display means which indicates when the pressure sensor has responded.
  • a display means may e.g. be formed by pressure destructible membrane. As a result, it can be detected in a later check, in which tank chamber the pressure sensor has responded.
  • Fig. 1 shows the tanker vehicle with a device according to the invention to a stationary filling plant.
  • Fig. 2 shows schematically an overfill sensor with associated pressure sensor.
  • FIG. 3 shows very schematically a tanker vehicle with a device according to the invention.
  • a tank 10 of a tanker not shown, which has four tank chambers 12 to 18 is indicated.
  • the tank chambers are assigned bottom valves 20 to 26, which also serve as filling valves.
  • the valves 20 to 26 are suitable actuators, e.g. associated with pneumatic actuators that open and close the valves. The actuation takes place via the control device 30.
  • the gas escaping during the filling of the tank chambers 12 to 18 is returned via a gas return line 32 to a filling system 42, as is the requirement.
  • detonation fuses 36 In the supply lines to the line 32 sit detonation fuses 36.
  • Another line 34 is connected to the filling system 42 and the associated control device 30.
  • overfill prevention sensors 38 respond when the level in the tank chambers 12 to 18 has reached a predetermined value. If this is the case, the filling of the tank chambers is terminated by the bottom valves 20 is closed and the supply of liquid is terminated. Alternatively, the filling valves are actuated in loading arms of the filling system. In that regard, the device described is state of the art.
  • an overfill prevention sensor 38 is shown very schematically. It consists of an optical sensor 40 and a pressure sensor 42, which is integrated into the housing of the optical sensor 40. In a feed line 44 to the optical sensor, a switch 46 is arranged, which is actuated by the pressure switch 42.
  • a quiescent current through which in the Control device is displayed in the filling system 30 that the filling is released or can be continued.
  • a modified flow is released to stop the filling.
  • the switch 46 is opened via the pressure sensor 42, thereby interrupting the quiescent current.
  • a control device 40 in the stationary filling system 42 is shown.
  • the control device 40 is connected via control lines 44, 46, 48 with filling valves 50, 52, 54 of the filling system 42.
  • the filling valves 50 to 54 are associated with bearing arms 56, 58 and 60 of the filling system 42, which can optionally be coupled to one of the bottom valves 20 to 26. If, as described above, due to the response of the pressure sensor 42 (FIG. 2), a fault occurs on the signal line 34, the control device 40 responds and closes the filling valve 50, 52 or 54 concerned in order to interrupt the filling of the relevant tank chamber ,
  • control device 30 of the tanker vehicle 10 ensures that when the pressure sensor 38 is addressed, the filling is stopped by closing the corresponding bottom valve 20 to 26.

Abstract

L'invention concerne un dispositif pour remplir des chambres d'un camion citerne par le biais de vannes de remplissage à partir d'une installation de remplissage stationnaire. Les chambres peuvent être connectées à l'installation de remplissage par le biais d'une conduite de retour de gaz, chaque chambre présente en outre un capteur de protection contre le débordement, les capteurs de protection contre le débordement peuvent être connectés par le biais d'une conduite de signal à un dispositif de commande et le dispositif de commande peut être connecté à des dispositifs d'actionnement pour les vannes de remplissage afin de les ouvrir et/ou de les fermer de manière sélective. L'invention est caractérisée en ce que les capteurs de protection contre le débordement sont associés dans les chambres du camion-citerne à un capteur de pression respectif, qui fournit un signal à la conduite de signal lorsque la pression dans une chambre dépasse une valeur prédéfinie et le dispositif de commande amène alors par le biais du dispositif d'actionnement concerné la vanne de remplissage associée à la chambre dans la position de fermeture.
