Definitions
- the invention relates to a device for conveying a medium according to the preamble of claim 1.
- the invention further relates to a method for conveying a medium according to the preamble of claim 18.
- a tanker In the field of dairy farming, a tanker regularly drives to certain milk producers and takes the milk that it has accumulated over the course of a day, for example, from one or more storage containers. With this milk acceptance, it is important that the quantity of milk removed is measured and registered precisely, since this is the basis for a later settlement between the producer and the customer. This measurement of the milk quantity is subject to calibration law, which prescribes how the measurement is to be carried out and the accuracies that must be observed (DIN 19217).
- One way to carry out a measurement that meets the calibration law is to use flow meters, but make sure that air in the case of narrowings that are inevitable when the milk is sucked in, especially at the start and end of the acceptance process, they do not get into the flow meter and lead to measurement errors there.
- Such air admixtures are avoided by inserting gas detectors and gas separators, which are also referred to as air separators.
- air separators are arranged as an intermediate container between the tank to be filled and the removal container. The milk to be conveyed remains in the air separator for a while, so that air pockets can recede in the milk. Only then is the milk passed, for example, through a flow meter into the tank to be filled, in order to carry out a quantity determination that meets the calibration requirements.
- a security system for a tank arrangement consisting of several tanks is known, with which the filling and / or emptying of the tanks can be controlled by a line device.
- a filling level measuring device for determining the position of at least one interface of the medium in the tank is also provided inside each tank. It is an object of the invention to provide a device or a method for conveying a medium, in which or by filling one of several tanks with a medium that differs from the media to be filled into the other tanks without great effort and if the medium to be filled in is mixed with the other media, if at all possible, this is possible.
- the invention builds on the generic device in that several tanks can be filled and / or emptied via the line device, that full level measuring devices are provided essentially inside the tanks for determining the position of at least one interface of the medium in the tanks. In this way it is possible to carry out a volume determination that meets the calibration requirements. Furthermore, the raw milk can be separated according to the different quality levels during the acceptance process without contamination.
- the line device has a distributor device with a primary side and a secondary side, the secondary side having individual, lockable distribution paths which are connected to the tanks.
- This distribution device is used to ensure the quality of the milk from milk of different quality levels, for example the separation of conventional raw milk and organic milk.
- the distributor device has level measuring devices which are assigned to the distributor routes. about The level measuring devices monitor the flow rate of the medium. Furthermore, the fill level measuring devices in the distributor device serve to provide an output signal when preparing the system for milk acceptance into the next tank, namely when the milk has been displaced to a sufficient extent from the acceptance system.
- the device is cheaper and lighter due to the dispensability of the air separator. It also takes up less space. Since the suction power is not limited by an air separator, a higher delivery rate can be provided.
- the primary side is preferably connected to a suction device.
- This suction device is used to convey the milk from a container provided by the supplier.
- the suction device advantageously has a first suction tank, a centrifugal pump and an ejector.
- a negative pressure can be generated in the suction tank via the ejector, which works on the principle of a water jet pump. This negative pressure fills at least one distributor path of the distributor device up to a predetermined fill level.
- the centrifugal pump then takes over the delivery, whereby the ejector, which works as a vacuum pump, can only be optionally supplied if required. Whether such a need exists is preferably determined in the distributor device by level measurement.
- a vortex breaker is advantageously arranged in the suction area of the centrifugal pump. This reduces the amount of air entering the centrifugal pump, which otherwise could significantly reduce the efficiency of the centrifugal pump.
- the suction device can be connected to a feed line.
- This supply line connects the suction device to the supplier's container.
- the suction device is not necessarily connected to a feed line, which can be explained in particular with regard to the delivery of the milk from the tanks described below.
- the suction device can be connected to a compressed air connection.
- Compressed air which removes the remaining milk from the suction system, can be fed into a specific tank via this at the end of the milk intake. the system is therefore available for the acceptance of milk into another tank.
- the suction device preferably has a level measuring device.
- An output signal from this level measuring device shows, for example, that the suction work of the ejector can be carried out by the centrifugal pump.
- a discharge opening is provided between the suction device and the primary side of the distributor device and that the distributor paths connected to the tanks on the secondary side of the distributor device are connected to the suction device via a pump-around line.
- This arrangement of the device according to the invention serves for the selective delivery of the milk from a selected tank via the suction container. This has the advantage that the same components that were used when the milk was accepted are for example, the suction container and the ejector can be used to dispense the milk.
- the suction device comprises an impeller pump.
- Impeller pumps are self-priming, which simplifies the system. Furthermore, impeller pumps are inexpensive, which brings advantages. In comparison to the system with vacuum pump and centrifugal pump, however, it should be noted that the milk is accepted less gently; Furthermore, the suction power is lower than in the system with a centrifugal pump and a separate vacuum pump. Depending on the desired application, the advantages and disadvantages of the embodiment will be weighed up against one another and the corresponding system will be used.
- an intake device in particular an impeller pump, is provided for each tank. This prevents mixing of the different acceptance parts in the suction device.
- Another embodiment of the invention works by creating a first negative pressure in the tanks. Due to the negative pressure in the tanks, the liquid product is sucked into the tank when a corresponding valve is opened. Mixing the milk in a suction device is thus also effectively avoided.
- a second suction container can be connected to the tank, in which a second negative pressure can be generated, the first negative pressure being able to be generated independently of the second negative pressure is.
- This arrangement has the advantage that a relatively small suction container is first evacuated, while the tank maintains its already generated negative pressure in its large volume. Only when the suction container is filled, which can be detected by a sensor, is the product conveyed from the suction container into the tank by actuating valves.
- the fact that the first negative pressure in the tank is generated independently of the second negative pressure in the suction container prevents the ingress of air at the beginning or at the end of the assumption from causing a premature pressure rise in the tank; this would mean that the large tank volume would then have to be evacuated again.
- the volume of the second suction tank is at least as large as the volume of the suction system.
- the suction container can therefore accept all of the milk that is in the suction system (hose plus piping). This is also useful in order to avoid the mixing of successive acceptance parties.
- the device according to the invention is particularly advantageous if the fill level measuring device has a transsonar displacement transducer which works on the aggressive principle and is coupled to a computing device and is equipped with the dipstick and at least one float, the float being equipped with at least one magnet.
- the magnetostrictive principle is based on the phenomenon that two crossing magnetic fields cause a deformation of the metal in which they are bundled. If an excitation current pulse is now added to the dipstick, this results in an excitation magnetic field that is axially symmetrical with respect to the dipstick. This interacts with the crossing magnetic fields of the float magnets, whereby a brief deformation and a resulting ultrasonic pulse is generated in the dipstick acting as a waveguide.
- the position of the magnets and thus of the float can be deduced from the transit time of the ultrasonic pulse through the dipstick to a receiver which is preferably arranged at the end of the dipstick.
- the device equipped in this way makes it possible to measure the position of the float up to an order of magnitude of ⁇ 10 ⁇ m.
- Transsonary displacement transducers are also long-term stable and thus meet the strict legal regulations regarding calibration and measuring accuracy.
- a control device is preferably provided which controls the conveyance of the medium as a function of the measurement signals of the fill level measuring device of the tanks and / or the fill level measuring devices of the distributor device and / or the fill level measuring device of the output device.
- At least one pressure sensor and / or at least one temperature sensor and / or at least one volume flow measuring device are provided, while output signals can be fed to the control device as input signals.
- quality assurance in milk acceptance or milk delivery can be further improved.
- the connections of the line device can be equipped with other system components with reading devices and coded devices (TAGs), so that the correct assignment of the components can be checked via a controller. For example, this can ensure that milk is only accepted or dispensed if all system components are correctly connected.
- TAGs reading devices and coded devices
- the medium is conveyed into a distribution path of a distribution device of the line device which is connected to the tank to be filled.
- air is also conveyed into the line device together with the medium.
- the filling is continued until the registered fill level falls below a predetermined level.
- the opened distribution route is closed to complete the filling. In this way it is achieved that the line device is free of medium residues up to the blocked distribution path.
- the blocked distribution path between the blocking point and the tank contains a defined volume, so that the total volume of the medium filled in the tank can be calculated easily and very precisely.
- the method is particularly advantageous in that a tank is selected which is to be filled with the medium, that a vacuum for filling the line device is generated in a suction device, that a fill level is determined in the suction device and that depending on the determined fill level Promotion of the medium by the management facility in the selected The tank begins and the generation of the vacuum is ended.
- This ensures that the level determination in the suction device can serve as a criterion for the process sequence, in particular also for determining the completion of the filling.
- the fact that the filling should be ended is shown by the fact that the fill level in the suction device falls below a predetermined value.
- At least one further tank is preferably filled after the selected tank has been filled. This is possible because the level determination, in particular after the milk has been expelled from the acceptance system by compressed air, ensures that the acceptance system is sufficiently freed from milk residues from the previous acceptance.
- a centrifugal pump is preferably operated to convey the medium.
- a vacuum pump for example using an ejector
- a centrifugal pump enables a large delivery rate; this also ensures gentle milk production.
- the vacuum pump generating the negative pressure is operated in support of the centrifugal pump when the fill level determined in the suction device falls below a predetermined level. If, for example, the fill level determined in the suction device falls below the predetermined level, this can be due to an insufficient delivery capacity of the centrifugal pump. In this case, the vacuum pump can be automatically started up so that the fill level in the respective distribution path again reaches its target level. In this context, it is particularly preferred that the start-up of the centrifugal pump and / or the supportive start-up of the vacuum pump and / or the completion of the filling of a tank is or are also controlled as a function of the determined fill level in the distributor device. The level determination in the distributor device thus serves to control several processes during the course of the process.
- the medium is preferably discharged from the tank by selecting a tank, pressing at least part of the medium into a suction container via a pumping line and discharging the medium from the suction container through a discharge opening arranged between the suction container and the distributor device.
- This ensures that no mixing occurs when the milk is dispensed. It is particularly advantageous that system components are used that were useful when the milk was accepted. It can also be advantageous if a first negative pressure is generated in a tank, so that the tank is filled with the conveyed medium. With this method, an additional suction device is unnecessary, so that mixing naturally cannot occur in such a suction device.
- a second negative pressure is generated in a second suction container, which is connected to the tank, independently of the first negative pressure, the second suction container and then the tank being filled with the conveyed medium.
- This has the advantage that the relatively small suction tank is first evacuated, while the large-volume tank maintains its already generated negative pressure. Only when the suction container is filled, which can be detected, for example, by a sensor, is the product conveyed into the tank, preferably by a non-return valve, by switching valves and suppressing the tank.
- the invention is based on the surprising finding that it is possible to meet both the strict calibration regulations and the quality requirements. On the one hand, this is achieved by a highly precise volume determination within a tank using a fill level measuring device, which makes additional air separators unnecessary. The quality of the milk can also be ensured in this way.
- the device according to the invention is in Compared to the devices of the prior art cheaper and lighter; it takes up less space and is able to perform better. The device makes it possible to accept milk with numerous different quality levels without significantly increased equipment expenditure. In the prior art it was necessary to use a separate air separator for each quality level; the invention only requires a corresponding number of tanks and a corresponding design of the piping system.

- a plurality of tanks 14 filled or fillable with a medium 10 are connected to a line device 12.
- Full-level measuring devices 16 are provided within the tanks 14.
- the full level measuring devices 16 comprise a dipstick 20 and a float 56, so that an interface 18 of the medium 10 can be measured with the filling level measuring device 16.
- the line device 12 comprises a suction lance 64, a suction hose 66 and a feed line 40 to a suction device 30 with a suction tank 32.
- the suction tank 32 is connected via a vortex breaker 38 to a centrifugal pump 34 which can be driven by a drive motor 68.
- the centrifugal pump 34 is connected to the primary side 24 of a distributor device 22.
- the secondary side 26 of the distributor device 22 opens into the tanks 14 via distributor paths 28, three of which are shown here by way of example.
- the feed line 40 to the suction container 32 is provided with further components: a vacuum switch 70, a temperature sensor 72, a disk valve 74, a milk test ring valve (MPR valve) 76, a volume flow meter 78, an online sampler 80 and a further disk valve 82.
- An ejector 36 is arranged on the suction tank 32 via a valve 83.
- the ejector 36 is equipped with a compressed air valve 84.
- the intake container 32 with a compressed air connection 42 in connection.
- a compressed air line 86 is equipped with a compressed air reducer 88, a filter 90 (eg 200 ⁇ m) and a shut-off valve 92.
- the suction container 32 is provided with a fill level measuring device 44 and with sight glasses 94.
- the distribution device 22 is also equipped on its various distribution paths 28 with level measuring devices 46.
- the distributor device 22 is equipped with disk valves 96, 98 both on its primary side and on its secondary side 26. Sight glasses 100 are also
- the device When receiving milk, the device according to the invention functions, for example, as follows. At the beginning of the acceptance, the corresponding tank 14 (tank segment) is selected on the basis of the milk quality to be assumed (default). For this purpose, the corresponding valve 96 on the distributor device 22 is opened. A check valve (not shown) prevents the backflow of milk, which may already be in the tank 14. A negative pressure is then generated in the suction tank 32. This takes place via the ejector 36 in connection with the valve 82 and the compressed air valve 84. In principle, the ejector 36 can be operated by a. other types of vacuum pump can be replaced. When the vacuum has reached a certain value, the milk begins to be pumped. At this time, the disc valve 74 and the valve 82 are open.
- the vacuum switch 70 detects the negative pressure.
- the milk is conveyed past the temperature sensor 72 via the suction lance 64 and the flexible suction hose 66.
- the temperature sensor 72 is used for additional quality assurance.
- the milk then passes into the volume flow meter 78, in which the current volume flow is determined.
- the values of the volume flow meter 78 (speed and degree of filling) become controlled by a control unit (not shown) together with any other values of the online sampler 80.
- the sample is filled into a sample bottle (not shown); this also serves quality assurance.
- the drive motor 68 of the centrifugal pump 34 is activated and the centrifugal pump 34 forces the milk into a line which leads to the primary side 24 of the distributor device 22.
- a vortex breaker 38 is installed in the inflow area of the centrifugal pump 34. Any air entering would not falsify the measurement of the milk volume, since the milk in the tank 14 has sufficient time to outgas; however, venting is recommended in order to improve or maintain the efficiency of the centrifugal pump 34.
- the vacuum pump or the ejector 12 can be switched off since the centrifugal pump 32 now provides for the delivery of the milk.
- the ejector 36 intervenes only when the level in the suction tank 32 drops below the predetermined level marked with a triangle, which can be observed on the sight glasses 94. This level detection takes place via the fill level measuring device 44 in the suction container 32. Towards the end of the acceptance process, air is also sucked in, the level in the suction container 32 drops, and the ejector 36 sucks the suction system free of milk residues.
- a milk test ring valve 76 (MPR valve) is provided in the described embodiment, which ensures that no new acceptance can be started before the current acceptance is completed. This happens because the MPR valve 76 opens and thus the intake system is flooded with air.
- the valve 82 which acts as a check valve valve can be designed, closed, whereupon the system is pressed empty. This empty pressing of the system takes place through the use of compressed air, which is applied to the compressed air connection 42 and thus reaches the suction tank 32.
- the compressed air is passed through a compressed air reducer 88 with a filter and water-oil separator and a shut-off valve 92 and is thereby reduced to a pressure which is harmless to the system.
- the fill level measuring device 46 can be a level switch, but also a continuously measuring device, in particular a dipstick device.
- the piping of the system is designed in terms of flow technology so that there are no siphons or recesses. This ensures that the milk flows off independently. Thus, the amount of adhesive milk remaining is small and minimal contamination occurs on the next acceptance.
- FIG. 2 shows a section of the device shown in FIG. 1. However, the device shown has additional components which are used for dispensing milk from the tanks. The same reference numerals refer to the same components.
- a pumping line 50 is connected via the butterfly valves 98 on the secondary side of the distributor device 22.
- This pump-around line leads via a pump-around disk valve 104 to the suction tank 32.
- the pump-around line 50 is provided with a residue valve 110.
- An output disk valve 106 is arranged between the centrifugal pump 34 and the primary side 24 of the distributor device 22.
- a dispensing opening 48 designed as a valve is located between this dispensing disc valve 106 and the centrifugal pump 34. In the region of the dispensing opening 48, a level meter 108 is additionally provided.
- valve 82 When dispensing milk from a tank 14, the device functions as follows. Valve 82 is initially closed and the system is depressurized. The empty pressing took place, for example, after a previous milk intake.
- the desired tank 14 (tank segment) is now selected by opening the corresponding valve 98.
- the pump-around disk valve 104 is also opened.
- the milk is now pressed into the suction container 32 by gravity or sucked in by the ejector 36 or any vacuum pump via a vacuum.
- the valve 106 is already closed at this time.
- the valve of the discharge opening 48 is opened.
- the centrifugal pump 34 is then activated. As a result, the milk is dispensed through the dispensing opening 48. If a partial delivery of the milk takes place, only the level difference that has arisen in the corresponding tank segment is determined via the fill level measuring device 16 and converted accordingly in terms of volume.
- the additional volumes for example the volume of the pumping line 50
- the additional volumes for example the volume of the pumping line 50
- the last partial volume from the fill level shown in the distributor device 22 to the check valve 102 is conveyed by a short pressure surge, the disk valve 96 and the dispensing disk valve 106 being open while the valve of the dispensing opening 48 is closed.
- the last partial volume is pressed into the area that leads to the tank 14 and into the volume of the pumping line 50.
- the respective sensor 46 detects this state.
- the partial volume is then conveyed into the suction container 32 by means of negative pressure.
- the system is pressed empty - the dispensing disk valve 106 is closed, the valve of the dispensing opening 48 is open. This empty pressing continues until the sensor 108 responds. Overall, a volume-based delivery was carried out in this way without significant contamination.
- FIG. 3 shows another embodiment of a device according to the invention. Comparable components are with the marked with the same reference numerals.
- the special feature of this embodiment is that an impeller pump 52 is provided as the suction device 30.
- the impeller pump 52 is connected to the primary side 24 of the distributor device 22 via a valve 114. Seen from the valve 114 downstream in the direction of the distributor device 22, a compressed air connection 42 can also be provided. Since this is optional, it is shown here with broken lines.
- the impeller pump 52 is self-priming, the system is simplified considerably. For example, no additional vacuum pump, for example designed as an ejector, is provided. However, the milk is not taken up by the impeller pump 52 as gently as is done, for example, by the combination vacuum pump / centrifugal pump of the embodiment shown in FIG. 1; furthermore, an impeller pump 52 does not provide the same power as the combination vacuum pump / centrifugal pump according to FIG. 1. However, an advantage of the impeller pump 52 is that it represents a cheaper solution.
- the impeller pump 52 sucks in the milk and presses it into the selected tank 14 with the valve 114 open.
- the vacuum switch 70 responds, the impeller pump 52 continues to be operated for a certain time in order to remove the residual milk from the suction system.
- the impeller pump 52 is then switched off and the valve 114 is closed.
- Valve 92 is opened while valve 112 remains closed.
- the milk remaining in the pipe system is pressed down to the level indicated by a triangle in the distribution device 22.
- the valve 92 is then closed and the pipe system is vented via the valve 112.
- the administration which connects the compressed air connection 42 to the line device 12 can be protected against the ingress of milk by a valve (not shown); this simplifies the cleaning of the system.
- FIG. 4 shows a part of the device shown in FIG. 3, which is comparable to that in FIG. 3.
- the same components are identified by the same reference symbols.
- FIG. 5 shows a device which can be used advantageously within the scope of the invention.
- a tank 14 is shown, which is filled with a medium 10, for example milk.
- the medium 10 has an interface 18, which is measured by the fill level measuring device 16 with its dipstick 20.
- a line device 12 is connected to the tank 14.
- the fill level measuring device 16 with dipstick 20 is operated with a negative pressure generated in the tank 14.
- the advantages of the fill level measuring device 16 with dipstick 20 have a particularly clear effect in this device.
- tanks 14, which work with negative pressure the entire tank is evacuated to a certain negative pressure. The minimum pressure is determined by the shape stability of the tank. This negative pressure then draws the liquid product into the tank 14 when the corresponding valve 122 is opened. This results in particularly low contamination.
- the filling and the dispensing take place on the same side of the tank 14.
- the system is shown as an example without sampling, which is still in demand abroad.
- the product After opening the valve 122, the product reaches the tank 14 via the flexible suction hose 118, which is connected to the fill-discharge nozzle via a coupling 120.
- the fill level measuring device 16 with its dipstick 20 can, besides determining the volume also serve as overfill protection.
- a sensor 124 is provided.
- FIG. 6 shows a further device which can be used advantageously in the context of the present invention. This is also a vacuum system. In contrast to FIG. 5, however, the filling of the tank 14 takes place from above, while the delivery takes place on the underside of the tank 14.
- the line device 12 on the filling side has a valve 128, as does the line tion device 12 has a valve 122 on the delivery side.
- FIG. 7 is an expanded variant of the embodiment according to FIG. 6.
- an intake container 54 is provided here.
- This arrangement has the advantage that the relatively small suction container 54 is first evacuated, while the tank 14 maintains its already generated negative pressure. Only when the suction container 54 is filled, which is detected by the sensor 130, is the valve 128 closed and the valve 122 is opened. Due to the negative pressure in the tank 14, the product is conveyed into the tank 14 through the check valve 132. It is particularly advantageous if the negative pressure in the suction container 54 is not connected to the negative pressure in the tank 14. This prevents an air inlet at the beginning or at the end of the assumption from leading to a premature pressure increase in the tank 14; because if this happens, the large volume of the tank 14 would have to be evacuated again.
- the suction container 54 is dimensioned such that it can hold the volume of the suction system.
- FIG. 8 shows a distributor device 22 which can be used advantageously in the context of the present invention.
- Reading devices 58 and coded devices 60 are arranged on the connections between the tubes 134 and the respective lines 136, 138. Readers 58 are able to read the code of TAGs 60 and input the result of a controller 62.
- the transmission from the reading devices 58 can take place via fixed cabling or via a remote transmission device 140. The latter can send out radio or infrared signals, for example.
- An overfill prevention device 142 can also be arranged in the system.
- the system can now be designed in such a way that the valves 146 to the tanks 14 are only released for opening by the control if the correct codes or the corresponding reading signals are read by the reading devices 58 and read by the TAGs 60. This increases safety when taking in milk, since it prevents inadvertent mixing due to incorrect connection.
- the connections between the lines and the hoses can be sealed by a seal 144.
- the TAGs and TAG readers could be omitted on land.
