Definitions

  • the invention relates to a suction system according to the technical features of the first claim.
  • Rail-based transport for passengers is subjected to strict safety and maintenance regulations.
  • the trains are cleaned, for example using a fresh-water supply and the solid-waste containers of the wagons, for example sewage container are drained.
  • the cleaning and maintenance activities are performed at various service points of the station and are quite time-consuming.
  • the maintenance and cleaning work is often gathered on a common service platform.
  • Such a common service platform is for example described in DE20001916U .
  • Specific technical requirements are to be met for the disposal of solid waste containers.
  • the sewage is disposed of mainly by a suction system, while water points are needed in order to fill the water tanks in the passenger trains. Both systems can be combined in a single platform using separate water supply and sewage lines. Compliance with hygiene rules is assured by excluding an accidental contact between fresh water and sewage lines.
  • tubing lines for liquids are typically made of plastic materials, for instance because plastic tubing is cheap and relatively easily made watertight; tubing lines for aerosols, for example solid and/or liquid aerosols, typically made of metals, often earthed, in order to avoid the built-up of static friction charges in the tubing.
  • tubing lines for liquids are typically made of plastic materials, for instance because plastic tubing is cheap and relatively easily made watertight; tubing lines for aerosols, for example solid and/or liquid aerosols, typically made of metals, often earthed, in order to avoid the built-up of static friction charges in the tubing.
  • Combining both functions in a single line would be very complicated and expensive since the aggressive chemical environment of the sewage would require the use of stainless steel tubing and would cause hard-to-solve sealing problems between the different sections of the tubing.
  • EP-A-2338761 discloses a suction system for cleaning train with a suction unit for suction of sewage being connected to a liquid container and a suction inlet. The invention therefore aims to provide a cost-effective and simple system allowing the suction of both liquids such as sewage and solid and/or liquid aerosols while avoiding suction of liquid such as sewage by and into the second suction unit.
  • the invention provides a system comprising at least two separate suction units, with the first suction unit for suction of liquids, for example sewage, being connected to a liquid container for storing the sucked liquid and with the second suction unit for suction of aerosols, for example liquid aerosols and/or solid aerosols, being connected to an aerosol container for storing the sucked aerosols, wherein the two suction units are connected to a single line, to which at least a first suction inlet for liquids and a second suction inlet for aerosols, for example solid and/or liquid aerosols, are connected, with at least one valve arranged such that at suction of the second suction unit the first suction inlet is substantially closed or even closed.
  • Such a system would allow suction of both liquids such as sewage and solid and/or liquid aerosols through the same single line since contamination of the second suction unit with for example sewage drawn in through the second suction inlet is avoided by the presence of the valve which ensures that at suction of the second suction unit only liquid aerosols and/or solid aerosols are drawn in by substantially, preferably completely closing off the first suction inlet using the valve.
  • the first suction inlet being closed off by the valve, the second suction inlet being open and the second suction unit operating, will allow the aerosols to enter the single line aspired by the second suction unit and substantially only liquid aerosols and/or solid aerosols are drawn in.
  • the second suction unit is a vacuum cleaner, for example further comprising a cyclone separator and/or a filter, in order to remove the aerosols, preferably liquid aerosols and/or the solid aerosols, respectively, from the air stream which is drawn in by the second suction unit, keeping the second suction unit substantially free from for example dust and water droplets which could hamper the operation of the second suction unit.
  • the second suction unit is connected to an aerosol container, which preferably is a dust container. Suction by first suction unit of liquid aerosols and/or solid aerosols drawn in through the second suction inlet does however affect the operation of the first suction unit less or even not at all and is not regarded as an obstacle to the functioning of the first suction unit.
  • the first suction unit is connected to a liquid container, which preferably is a sewage container.
  • the system comprises at least one valve mounted between the first suction inlet and the single line or mounted at the junction of the first and second suction inlet with the single line.
  • the presence of at least one valve mounted between the first suction inlet and the single line ensures that at suction of the second suction unit only liquid aerosols and/or solid aerosols are drawn in and avoid contamination of the suction unit, by closing the valve, thereby closing off the supply of liquids and in particular sewage.
  • the presence of at least one valve mounted between the second suction inlet and the single line ensures that at suction of the first suction unit only liquid, more in particular sewage is drawn in and avoids contamination of the suction unit, by closing the valve, thereby closing off the supply of aerosols.
  • a valve may be mounted at the junction of the first and second suction inlet with the single line, which may close off, depending on which suction unit is operating, either the first or the second suction inlet.
  • the system comprises at least one valve mounted between the single line and second suction unit or mounted at the junction of the first and second suction unit with the single line.
  • the presence of at least one valve mounted between the single line and second suction unit ensures that at suction of the first suction unit no liquids and in particular sewage are drawn in and avoids contamination of the second suction unit, by closing the valve, thereby closing off the supply of liquids, in particular sewage.
  • the presence of at least one valve mounted between the single line and first suction unit ensures that at suction of the second suction unit no aerosols are drawn in and avoids contamination of the first suction unit, by closing the valve, thereby closing off the supply of aerosols.
  • a valve may be mounted at the junction of the first and second suction unit with the single line, which may close off, depending on which suction unit is operating, either the first or the second suction unit.
  • valves mounted between the first suction inlet and the single line or the second suction inlet and the single line or mounted at the junction of the first and second suction inlet with the single line with valves mounted between the single line and first and/or second suction unit or mounted at the junction of the first and second suction unit with the single line.
  • the system comprises at least two valves between the first or second suction units, more preferably the second suction unit, and the single line and a pressure gauge between the two valves.
  • This configuration offers a supplementary safety feature, especially in the case the two valves are mounted between the second suction unit and the single line.
  • liquid for example sewage is accidentally drawn in and passes between the two valves, this would result in a change in pressure, for example a drop, which would be detected by measuring the pressure with the pressure gauge.
  • a drop in pressure could for example automatically result in the shut-down of the second suction unit and/or closing of any further valves, for example any valves provided in between the first suction inlet and the single line, thereby protecting the second suction unit from contamination by the sewage.
  • the single line is made from a plastic material, preferably polyethylene and preferably, the single line is earthed, preferably wherein the single line is made from a plastic material, it is connected to an earthed conducting wire, with the conducting wire running along the longitudinal direction of the line.
  • the single line is preferably made of a plastic material, since such tubing is easily sealed, which is important for liquid, especially sewage flows but also for reasons of cost, since such tubing is relatively cheap, compared to other materials.
  • Polyethylene tubing is commercially widely available and is a material typically used when dealing with liquid flows, especially with flows of chemically aggressive substances, such as is the case with sewage.
  • a flow of liquid aerosols and/or solid aerosols may, however, lead to friction in the line of plastic material and result in the built up of static electricity in the tubing.
  • the built up of static electricity in tubing is a safety hazard and should be avoided, especially if the tubing is made from a non-conductive material such as the above-mentioned polyethylene. Therefore, the single line for example is earthed, for example by connecting it to an earthed conducting wire, for example with the conducting wire running along the longitudinal direction of the line.
  • the earthing of the conducting wire may be present at one or more positions along the wire.
  • the first and second suction inlets for liquids and for solid and/or liquid aerosols, respectively are part of a common service station.
  • a common service station may further comprise any one or more of: an outlet for warm water, soap/water, compressed air, potable water.
  • first and second suction inlets for liquids and for solid and/or liquid aerosols, respectively as part of a common service station.
  • these inlets may be provided in a space-saving manner and be used as a single point of service to for example a cleaning facility for vehicles.
  • the service station would not only provide inlets for the disposal of liquids and solid and/or liquid aerosols but also outlets for for example warm water and/or soap/water and/or compressed air could be provided and offer a more elaborate common service station for cleaning for instance vehicles etc.
  • the valves are controlled by a control module comprising a stack system, preferably a first-in-first-out stack system.
  • the control module for example takes as an input signal a user request to use one of the first and the second inlet and as an output signal a block/release signal to one or more of the valves. So for example a user desiring to suck liquid, for example sewage, performs a user request to do so, for example by pushing a first button, for example on the service station should it be provided. This request is then put on the stack and is for example performed when all previously recorded user requests have been finished by opening or closing the corresponding valves and putting the first suction unit into operation.
  • the user When the user desires to suck aerosols, for example dust, the user request to do so, for example by pushing a corresponding second button, for example on the service station should it be provided. This request is then put on the stack and is for example performed when all previously recorded user requests have been finished by opening or closing the corresponding valves and putting the second suction unit into operation.
  • a corresponding second button for example on the service station should it be provided.
  • This request is then put on the stack and is for example performed when all previously recorded user requests have been finished by opening or closing the corresponding valves and putting the second suction unit into operation.
  • multiple service stations are provided with respective first and second suction inlets connected to a single line, such a system makes it impossible that an operator puts the second suction unit into operation while the first suction unit is in operation such that sewage may nevertheless find its way to the second suction unit.
  • control module may be provided such that when several subsequent requests are present in the stack, for example several requests for sucking sewage or several requests for sucking aerosols through the mutual single line, they are nevertheless allowed at the same time such that these operations can be performed in parallel with respect to each other.
  • a traincleaning system comprising one or more systems according to the invention as well as a railway yard comprising the traincleaning system according to the invention, are preferred embodiments of the present invention.
  • the system according to the invention is particularly suited for use in a traincleaning system or facility, typically located on a railway yard.
  • Traincleaning systems need to be provided in such areas, adjacent to each train to be serviced. Access to trains should be designed so that cleaning staff can reach them safely whilst carrying their equipment, such as for example further tubing for example for connecting the first inlet to the sewage tanks of the train, for connecting the second inlet to a vacuum cleaner nozzle, brush, etc., which may be connected for example to the inlets and outlets of a common service station.
  • Several of such service stations may be present within the traincleaning system.
  • each common service station is connected to a central suction unit for each type of suction inlet; i.e.
  • the different inlets for solid and/or liquid aerosols could each be connected via a single line to a central vacuum cleaner, meaning that several operators could be vacuum cleaning simultaneously via different inlets.
  • a stack system could put the operators using a central sewage suction on hold until a certain number of operators have completed their cleaning, to make sure that only solid and/or liquid aerosols are drawn in by the central vacuum cleaner.
