Definitions

  • the present invention relates to a rail vehicle with a suction line.
  • the wet cells in rail vehicles also include the waste water tanks, in which the waste water from the toilets and hand wash basins is collected.
  • the waste water tank is emptied via a suction line at regular intervals.
  • a mobile or stationary extraction system is connected to an extraction connection on the outside of the vehicle. In the vicinity of the suction connection there is a ball valve or another shut-off valve with which the suction line is opened.
  • the suction system uses a pump to generate a negative pressure of minus 0.6 to 0.8 bar, which sucks the waste water out of the waste water tank.
  • the suction lines for internal waste water tanks are designed in such a way that the waste water is sucked in in the waste water tank, the suction line leads upwards out of the waste water tank and the suction connection is the lowest point of the suction line so that the waste water can be pumped easily.
  • a minimum and maximum height is specified for operation.
  • the vehicle contour also does not always allow the suction line to be laid with the suction connection as the lowest point.
  • the lowest point of the suction line cannot be completely emptied, because as soon as the waste water tank is empty, air is sucked in and the flow stops. Wastewater remains at the lowest point and cannot be sucked off. This wastewater can freeze in winter and damage or clog the suction line.
  • the U-shape is only one shape of the suction line which can be problematic and for which the present invention provides a solution.
  • suction line forms too, large amounts of waste water can disadvantageously remain in the suction line.
  • the suction line is interrupted, for example because the relatively small container in a mobile suction system is full, the suction line can disadvantageously remain filled with waste water.
  • the task is to develop a rail vehicle with a suction line in which residual or residual waste water can be removed from the suction line simply and inexpensively.
  • a rail vehicle which comprises a waste water tank. Furthermore, the rail vehicle comprises a suction line which is connected to the waste water tank and which is led from the waste water tank to a suction connection for sucking off the waste water.
  • the rail vehicle further comprises a shut-off valve which is introduced in the suction line and which opens the suction line in an open state and closes the suction line in a closed state.
  • the rail vehicle comprises a compressed air line which is connected to the suction line via a compressed air connection and is set up for this purpose when the Shut-off valve to introduce compressed air into the suction line via the compressed air connection, the compressed air connection being positioned between the shut-off valve and the waste water tank.
  • Compressed air means, in particular, compressed air which has a pressure of several bar, for example more than 5 bar, 8 bar or even 10 bar.
  • a compressed air line is a line which is designed to withstand compressed air and to conduct compressed air.
  • An external suction system can be connected to the suction connection to extract the waste water from the waste water tank.
  • a ball valve for example, can be used as the shut-off valve, although the invention is not restricted thereto.
  • the invention has the advantage that residual or residual waste water in the suction line can be blown back into the waste water container via the compressed air line by means of compressed air.
  • the compressed air flows through the compressed air connection into the suction line, is stopped by the shut-off valve when it is closed and builds up pressure between the shut-off valve and the remaining wastewater, whereby the remaining wastewater is pressed into the wastewater container.
  • the solution for emptying the suction line with a compressed air line is a simple means and increases operational reliability. Broken or clogged suction lines, as can occur, for example, due to wastewater freezing in the suction line, can lead to down times of the toilet and repair measures, which is avoided by the present invention by blowing wastewater into the wastewater container with compressed air.
  • the compressed air line is connected to the suction line in such a way that as little waste water as possible can penetrate the compressed air line.
  • the construction with the compressed air line is simple and can also be retrofitted for existing rail vehicles, since apart from the additional components, no structural changes have to be made.
  • the suction line preferably comprises a depression between the waste water tank and the shut-off valve, the compressed air connection being positioned between the depression and the shut-off valve.
  • a residual amount of wastewater typically remains within the suction line, in particular within the depression, during each suction process.
  • the compressed air line is preferably connected to a compressed air system positioned within the rail vehicle. This allows the suction line to be emptied solely on the rail vehicle side without a compressed air supply connected externally to the rail vehicle. As a result, emptying can also take place efficiently in terms of time and without any special effort.
  • the compressed air line preferably comprises a control valve which, in an open state, opens the compressed air line so that compressed air is fed into the suction line via the compressed air connection, and closes the compressed air line in a closed state so that no compressed air is fed into the suction line via the compressed air connection. This allows the supply of compressed air to the suction line to be controlled in a targeted manner.
  • the rail vehicle preferably comprises a control unit which is set up to open the regulating valve when the shut-off valve is closed. This can the compressed air supply is triggered fully automatically and the suction line is emptied.
  • the control of a wet room comes into consideration as a control unit, the invention not being restricted to this.
  • the shut-off valve preferably comprises a switch which is set up to send a signal to the control unit when the shut-off valve closes, the control unit being set up to open the control valve of the compressed air line in response to the signal.
  • a limit switch also called a position switch, is preferably used as the switch.
  • the control unit is preferably set up to close the control valve after a predetermined blowback time has elapsed. This also automatically terminates the introduction of the compressed air into the suction line.
  • the blowback time can be, for example, 10 or 20 seconds, the invention not being limited thereto.
  • the control unit is preferably set up to alternately open and close the control valve during the blowback time.
  • compressed air is introduced into the suction line in a pulsed manner.
  • the remaining wastewater can be blown back into the wastewater tank in an improved or more efficient manner.
  • less compressed air is advantageously consumed.
  • the wastewater container preferably comprises a level meter for measuring the fill level of the wastewater container, the control unit being set up to read in the fill level of the wastewater container and to keep the control valve closed or close above a maximum fill level.
  • the control unit being set up to read in the fill level of the wastewater container and to keep the control valve closed or close above a maximum fill level.
  • the suction line preferably comprises a pressure sensor which is positioned between the shut-off valve and the waste water container and is designed to measure the pressure within the suction line, the control unit being set up to open the control valve of the compressed air line or to keep it closed in response to the measured pressure . This can be used to check whether the suction line is full or blocked. For example, this can be done by means of a pressure surge of the control valve, which is then detected by the pressure sensor. The control unit can thus advantageously decide on the basis of the pressure measurement whether or not blowback should take place.
  • the pressure sensor is preferably positioned on the compressed air connection.
  • the suction line between the waste water tank and the shut-off valve preferably comprises a level meter for measuring the level in the suction line, the control unit being set up to read in the measured level of the suction line and to open the control valve of the compressed air line when the level is above a minimum level.
  • the blowback can thus be triggered as required if a minimum filling of the suction line is established or detected by means of the fill level meter.
  • the compressed air line preferably comprises a pressure reducer.
  • the compressed air system of a rail vehicle typically generates compressed air with a pressure of up to 10 bar. This can be too high for the blowback application required here.
  • a pressure reducer can throttle this pressure, for example the pressure can be reduced to 5 bar by means of the pressure reducer, which is for the specific application the blowback is sufficient.
  • a suitable pressure of the compressed air can thus be set with the pressure reducer.
  • the rail vehicle can also include a manual switch which is positioned on the outside of or in the rail vehicle and is set up to open the control valve of the compressed air line.
  • a manual switch which is positioned on the outside of or in the rail vehicle and is set up to open the control valve of the compressed air line.
  • the compressed air line can be routed to an external compressed air connection positioned on the outside of the rail vehicle. This means that an external compressed air system can be connected to the compressed air connection.
  • An external compressed air system can be connected to the compressed air connection.
  • FIG. 1 shows a rail vehicle 1 according to a first embodiment of the invention.
  • the rail vehicle 1 comprises a waste water container 10.
  • waste water which is generated by the use of fresh water by users / passengers on the rail vehicle 1 can be collected or temporarily stored.
  • a wastewater line 80 for gray water and / or black water can be routed from a wet room or from a toilet system 82 of the rail vehicle 1 to the wastewater container 10 and connected to the wastewater container 10 so that the wastewater can be directed into the wastewater container 10.
  • the rail vehicle 1 further comprises a suction line 20.
  • the suction line 20 is connected to the waste water tank 10 and leads from the waste water tank 10 to a suction connection 30 for sucking off the waste water.
  • the suction connection 30 is preferably attached to an outside of the rail vehicle 1 so that the waste water can be sucked out of the waste water container 10 and via the suction line 20 via this suction connection 30 with an external suction system that can be connected to the suction connection 30. Such suction can take place if necessary.
  • the rail vehicle 1 further comprises a shut-off valve 22 introduced in the suction line 20, which opens the suction line 20 in an open state and closes the suction line 20 in a closed state.
  • the shut-off valve 22 can be designed, for example, as a ball valve or shut-off valve.
  • the rail vehicle 1 also includes a compressed air line 40.
  • a compressed air line 40 is a line which is designed to convey compressed air, ie air at high pressure, for example in the range of several bar, such as 5 bar or 10 bar. Such a compressed air line 40 thus differs from a conventional line.
  • the compressed air line 40 is connected to the suction line 20 via a compressed air connection 42.
  • the compressed air connection 42 is positioned between the shut-off valve 22 and the waste water container 10.
  • the compressed air line 40 is designed to introduce or guide compressed air into the suction line 20 via the compressed air connection 42 when the shut-off valve 22 is closed.
  • the underlying principle of the invention is that compressed air which is introduced or fed into the suction line 20 via the compressed air connection 42 cannot escape via the closed shut-off valve 22. Rather, the compressed air presses or pushes or blows the remaining waste water in the suction line 20 back into the waste water container 10.
  • the waste water in the suction line 20 can be, for example, remaining or residual waste water after a suction process through a suction system.
  • Blowing back this waste water has the advantage that no waste water remains in the suction line 20 and thus, for example, freezing of this waste water and associated blockages or damage to the suction line 20 are avoided.
  • the designer of the rail vehicle 1 is much more free in the spatial planning of the rail vehicle, since the suction line 20 does not have to follow a strictly prescribed course.
  • the compressed air line 40 is preferably connected to the suction line 20 in such a way that as little waste water as possible can penetrate into the compressed air line 40.
  • a check valve 49 can be introduced in the compressed air line 40, the invention not being restricted to this.
  • this check valve 49 can preferably be positioned in the vicinity of the compressed air connection 42, so that no waste water reaches the compressed air line 40 via the compressed air connection 42.
  • the invention can also be retrofitted for existing rail vehicles 1, since no or at least only a few structural changes have to be made.
  • the suction line 20 has a depression 24 between the waste water container 10 and the shut-off valve 22.
  • the compressed air connection 42 is positioned between the depression 24 and the shut-off valve 22.
  • the constellation that the suction line 20 has such a depression 24 is very often found in rail vehicles.
  • Such sinks 24 are critical points at which residual wastewater collects and can lead to damage, for example through freezing of the wastewater on the suction line 20 or blockages in the suction line 20.
  • the compressed air connection 42 is also positioned, for example, at the end of the rise in the depression 24 facing the shut-off valve 22.
  • the depression has a U-shape and forms a local minimum in the suction line 20 Waste water located in the sink 24 is blown back into the waste water container 10 by means of the compressed air with the shut-off valve 22 closed.
  • the compressed air line 40 is connected, for example, to a compressed air system 44 positioned within the rail vehicle 1.
  • the compressed air line 40 is therefore an internal compressed air line of the rail vehicle 1. This means that the suction line 20 can be emptied solely by the rail vehicle 1 itself and the compressed air lines 40 already in the rail vehicle 1 can be used to blow the waste water back into the waste water tank 10.
  • a control valve 46 is provided in this embodiment.
  • the compressed air line 40 In an open state of the control valve 46, the compressed air line 40 is open so that compressed air is fed into the suction line 20 via the compressed air connection 42.
  • the compressed air line 40 In a closed state of the control valve 46, the compressed air line 40 is closed, so that no compressed air can be fed into the suction line 20 via the compressed air connection 42.
  • a control unit 50 is provided in this exemplary embodiment.
  • the control unit 50 opens the regulating valve 46 when the shut-off valve 22 is closed.
  • the shut-off valve 22 can also have a switch 23, for example a limit switch, which detects or detects the closing of the shut-off valve 22.
  • the switch 23 can send a signal to the control unit 50 via a signal line S1 routed from the shut-off valve 22 to the control unit 50.
  • the control unit 50 can then in turn open the control valve 46 of the compressed air line 40 in response to the received signal.
  • a control signal can be sent via a control line S2 leading from the control unit 50 to the regulating valve 46.
  • the control valve 46 in this embodiment also has, for example, a switch 47, for example also a limit switch.
  • the control unit 50 preferably closes the regulating valve 46 automatically after a predetermined blowback time has elapsed.
  • a control signal can also be sent to the regulating valve 46, so that the regulating valve 46 is closed after the blowback time has elapsed.
  • the blowback time can be, for example, 20 seconds or, for example, 10 seconds, the invention not being restricted to these numerical examples.
  • the control unit 50 can also be set such that the regulating valve 46 is alternately opened and closed during the blowback time.
  • the compressed air is pumped into the suction line 20, which results in an improved or more efficient blowback in comparison can lead to a continuous supply of compressed air.
  • small residues of wastewater can thus be blown back better into the wastewater container 10.
  • the invention also includes the fact that compressed air is fed into the suction line 20 alternately, continuously and then in a pulsed manner.
  • compressed air can be fed continuously into the suction line 20 in a first time segment, so that a large amount of waste water is initially returned to the waste water container 10.
  • compressed air can then be fed into the suction line 20 in a pulsed manner, so that the remaining waste water is then returned.
  • the amount of compressed air is advantageously saved in pulsed operation.
  • FIG 2 shows a rail vehicle 1 according to a second embodiment of the invention. The following is compared to the Figure 1 only dealt with the differences.
  • the wastewater container 10 further comprises a level meter 12, for example a level sensor.
  • the fill level meter 12 measures the fill level of the wastewater in the wastewater container 10.
  • the control unit 50 can read in the fill level of the wastewater container 10. This can be done, for example, by means of a measurement data line M1, which connects the level meter 12 to the control unit 50, via which the level is transmitted to the control unit 50.
  • the control unit 50 can then keep the regulating valve 46 closed in the event that the fill level is above a maximum fill level, or alternatively close the regulating valve 46 if it was open. The latter can occur, for example, if the maximum fill level is only exceeded during blowback. It can thus advantageously be avoided that compressed air reaches an overfilled waste water container 10. This in particular reduces the risk of wastewater leaking in large quantities from the rail vehicle 1 via an overflow 14 of the wastewater container 10 or ventilation slots escapes.
  • An overflow 24 can in principle also be present in the other versions, even if not explicitly shown there.
  • the suction line 20 comprises a pressure sensor 26.
  • the pressure sensor 26 is positioned between the shut-off valve 22 and the waste water container 10. As in Figure 2 As shown, the pressure sensor 26 is positioned on the compressed air connection 42, the invention not being limited thereto.
  • the pressure sensor 26 is designed to measure the pressure within the suction line 20.
  • a measurement data line M2 which connects the pressure sensor 26 to the control unit 50, the measured pressure in the suction line 20 can be transferred to the control unit 50.
  • the control unit 50 can then open the control valve 46 of the compressed air line 40 or keep it closed in response to the measured pressure.
  • a small pressure surge can be used to check whether the suction line 20 is full or clogged.
  • blowback should take place by means of compressed air. If an overfill or blockage of the suction line 20 is determined, a warning can also be given to the service personnel, who then, for example, initiate a blowback from the outside, see the embodiment according to this Figure 3 , or by a manual switch, see the embodiment according to Figure 4 .
  • the suction line 20 can also include a level meter 28 between the waste water container 10 and the shut-off valve 22, as shown in the present figure, for measuring the level in the suction line 20. This can be positioned at a suitable point within the suction line 20, for example in the ascending part of the depression 24, the invention not being restricted to this.
  • the level meter 28 can detect whether the suction line 20 is full. If the suction line 20 is full, the measured fill level or the presence of wastewater can be transferred to the control unit 50 via a measurement data line M3. The control unit 50 can then be set up to read in the measured fill level of the suction line 20 and to open the control valve 46 of the compressed air line 40 when the fill level is above a minimum fill level.
  • the compressed air is then fed from the compressed air line 40 into the suction line 20.
  • This has the advantage that the blowback is only triggered when the level meter 28 actually also detects residual wastewater in the suction line 20. Superfluous blowback and thus waste of compressed air is therefore avoided.
  • the compressed air line 40 has a pressure reducer 48. This is positioned between the control valve 46 and the compressed air connection 42.
  • the compressed air system 44 of a rail vehicle 1 typically generates compressed air with a pressure of up to 10 bar, which may not be necessary or too high for the blowback present.
  • a pressure reducer 48 installed in the compressed air line 40 can independently reduce the pressure to a lower pressure, purely by way of example 5 bar.
  • the pressure reducer 48 can be used in particular to set a suitable pressure for the current blowback of waste water.
  • a specific implementation for the pressure reducer 48 can take place, for example, on the basis of empirical values. Furthermore, the problem of wastewater overflowing from the wastewater container 10 is prevented or at least reduced by the pressure reducer 48.
  • FIG. 3 shows a rail vehicle 1 according to a third embodiment of the invention.
  • the rail vehicle 1 assigns in comparison to Figure 1 in this embodiment a manual switch 60 or button.
  • a manual switch 60 or button This is attached to the outside of the rail vehicle 1.
  • the manual Switch 60 can also be positioned in rail vehicle 1.
  • the control valve 46 of the compressed air line 40 can be opened by service personnel, for example.
  • a control line S3 is provided between the switch 60 and the control valve 46 for transmitting a control signal.
  • the suction line 20 can thus be emptied by manual actuation, provided that the shut-off valve 22 is closed at the same time.
  • Manual triggering can also take place if, as in connection with Figure 2 described, an overfilling or clogging of the suction line 20 by a pressure sensor in this Figure 3 not shown due to clarity, is recorded.
  • FIG. 4 shows a rail vehicle 1 according to a fourth embodiment of the invention.
  • the compressed air line 40 is routed to an external compressed air connection 70 positioned on the outside of the rail vehicle 1.
  • An external compressed air system can be connected to this compressed air connection 70, which directs the compressed air into the suction line 20 when the shut-off valve 22 is in the closed position.
  • Such an embodiment of the invention does not require a control unit or any additional components, so that such an implementation can be implemented without any particular effort.
  • Such an embodiment can accordingly be retrofitted in a particularly simple manner.
