Definitions

  • the invention relates to a method and a device for filling liquids or gases, which have to be transferred from or into a mobile or stationary tank and in which the addition of a defined substance in a predetermined amount is necessary to achieve a desired mixing ratio.
  • the additives are principally self-mixing. For homogeneous mixing, however, it is necessary to switch off the oil heating for almost 24 hours. In addition to this ineffective downtime, the manual additive has proven itself as an additional and time-consuming process, which also only allows inaccurate dosing of the additive because of the standard liter fillings.
  • the invention has for its object to provide a method and an apparatus for filling liquids and gases, in particular heating oil, which ensure a simple and reliable addition of at least one additive in an exact dosage and a homogeneous mixing substantially without waiting.
  • the object is achieved in terms of method by the characterizing features of claim 1 and in terms of the device in accordance with the characterizing part of claim 3.
  • Advantageous and expedient refinements are contained in the subclaims and in the exemplary embodiments.
  • the basic idea of the invention is to add at least one additive to a filling quantity of a liquid or a gas in a predefinable mixing ratio during the entire filling process. Homogeneous mixing already takes place in the filling line into which the additive is injected continuously or discontinuously with the aid of a metering device and depending on the liquid or gas to be filled. The injections are determined with respect to the volume and the intervals as a function of the predetermined mixing ratio and the actual value of a quantity measurement in the filling line with the aid of an electronic control device.
  • the device according to the invention for filling liquids or gases provides a metering device in addition to a measuring device for detecting the amount, for example the volume, the liquid or gas to be filled before, which makes it possible to add at least one additive to the medium to be filled during the entire filling process.
  • the filling device according to the invention is particularly suitable for filling and for additizing heating oil, which is why only heating oil is referred to below as the substance to be filled.
  • other liquid or gaseous substances are not excluded.
  • an electronic quantity measuring device is connected to a measuring element arranged in the heating oil filling line, so that, for example, the temperature of the heating oil can be used to determine a temperature-corrected filling quantity
  • the injection device is a mechanically operated pump arrangement, in particular in the form of a compressed air pump, which is used to generate an injection pressure that is above the pressure prevailing in the filling line, for example two piston-cylinder units which can be actuated together and have a suction chamber for the one from the storage container Additive to be sucked and injected into the filling line.
  • the injection device can also be constructed as a piston-cylinder unit.
  • Air-loaded working piston can be designed to be double-acting, ie bidirectional, as well as the pressure piston injecting the additive into the filling line.
  • Drive pistons such as pressure pistons are rigidly connected to each other via a piston rod and clutch, so that an accurate and continuous tapping of the position is possible.
  • the area of the working piston is expediently designed to be larger in accordance with the higher injection pressure for injecting the additive into the filling line.
  • a sensor as a flow monitor, which is arranged, for example, near the injection point in the injection line. With such a sensor, it can be checked whether a stroke movement of the cylinders of the pump arrangement actually causes an additive.
  • the advantages of equipping a filling device with a metering device according to the invention are an exact and controllable and evaluable metering of the additive or additives.
  • the heating system is therefore always available. Since the supply of additive substances in cans or bottles can be omitted, the additive is no longer associated with the need to remove additional hazardous waste. Ultimately, time is saved in the entire filling process, for example from a mobile tanker.
  • a liquid to be filled for example heating oil
  • a tank container (not shown) in FIG. 1 via a filling line 8, in which a measuring element 3 for detecting the filling quantity, for example a flow sensor, is positioned.
  • a metering device 10 is provided, which has a storage container 11 for an additive, a microelectronic computing unit 21 connected to a control unit 15, and an injection device 20.
  • the control unit 15 calculates from a Specified amount, which was entered or stored by a corresponding preselection on the electronic computing unit 21, and the actual values of the flow sensor 3 in the filling line 8, the interval time that is required for a given injection volume determined by the position sensors 17, 18, 19 to start the batch injection of the additive.
  • control valve 33 which applies compressed air to both pistons 26, 26 'via the air supply line 30, is activated by the control unit 15, so that the pressure chambers 29, 29' of the injection device 20 are filled with air.
  • the control unit 15 By acting on both pressure chambers 29, 29 ', an increased total pressure is generated in the suction chamber 25, so that the additive contained therein can be injected into the filling line 8 via a check valve 24 and added to the heating oil.
  • a sensor 23 is arranged in the injection line 28 and expediently after the check valve 24.
  • This sensor 23 for example a flow meter operating on a differential pressure basis or an impeller flow meter, serves as a flow monitor for monitoring the additive by detecting whether an additive is actually being injected during a stroke movement of the pistons 26, 26 'or 52. Of course, the actual flow volume can also be determined.
  • the filling device according to the invention according to FIG. 1 also enables injection control as a function of the characteristic curve of the pump arrangement or the piston position.
  • a compressed air pulse of adjustable duration is applied to the pump cylinder arrangement 27, 27 'and then the position of the pistons 26, 26' is queried at the position sensors 16, 17, 18. In this way, any intermediate volumes can be set, and an exact determination of the delivered injection volume is possible by constantly summing up the piston position.
  • the characteristic curve of the pump arrangement can be stored in a programmable read-only memory (EEPROM).
  • the amount of additive present in the storage container 11 is monitored by at least one fill level sensor, the measured values of which are fed to the control unit 15.
  • a fill level sensor 9 is positioned for advance warning in such a way that a defined supply of additive material is displayed for the purpose of refilling.
  • a fill level detector 12 is arranged in a bottom area of the storage container 11, which, possibly with an adjustable delay, can actuate a shut-off valve (not shown) in the filling line 8 via the control unit 15. This makes it possible to interrupt the filling of heating oil if there is no longer any additive in the reservoir 11.
  • a check valve 14 is arranged in the intake line 13 in the same way as the check valve 24 in the injection line 28.
