The technical FIELD

The present invention relates to systems and methods to adjust the mode of transportation of material, means of transport and for use in an aircraft system to adapt the mode of transportation of the material.

BACKGROUND of INVENTION

The term "vacuum system" refers to a special pneumatic transport systems. Typically in such systems, the transportation of the material is due to the differential pressure, i.e. the material that must be transported, is captured by the fluid flow, which occurs as a result of the pressure difference, and as a transport medium, usually air is used.

In particular, in aircraft vacuum systems are used to transport waste from the cab, such as toilets or kitchens, Central reservoir-collection. In the proposed invention, the material is transported in tank-waste collection network of pipelines. Negative pressure in the tank-the collection towards the cabin pressure provides the necessary pressure difference.

In aircraft with pressurized cabins to create a negative pressure necessary for operation of the pneumatic transport system, use directly the difference between the pressure in the cabin and ambient pressure. If the pressure difference is insufficient, for example, in the Parking lot or at low altitudes, the required pressure difference is created by using a compressor.

Use of the pneumatic transport system for toilets aircraft is often accompanied by high noise levels. This noise even passengers in the cabin, and he creates some discomfort.

The usual measures to reduce noise at the source, the receipt of the transported material are in the closure of the transport system prior to descent, so that noise can be suppressed. In addition, the toilets are posted signs with instructions to passengers in respect of measures to reduce noise, for example, by closing the lid of the toilet. Up to this time the kinetic energy of the transported material was reduced at the inlet to the tank collection with safety devices to prevent damage and wear.

However, while the above measures to reduce noise are not effective enough, and a significant reduction in discomfort arising from passengers, does not occur.

The INVENTION

There is a need to reduce the level of noise generated in the pneumatic systems used for material handling.

In accordance with one aspect of this is about the invention features a system for adapting the mode of transportation of the material. The system includes at least one first reservoir, which can be connected to a source of a first pressure; at least one second tank, which can be connected to a source of a second pressure; and a connecting line for transporting material from the first tank (or from the first tank to the second tank (or second reservoirs). In addition, the system contains pressure reducer, which can be adjusted by the difference between the pressure in the first tank (or in the first tank and the pressure in the second tank (or second tanks).

In accordance with another aspect of the invention proposes a method to adapt the mode of transportation of the material. In this method, at least one first reservoir is connected to the source of the first pressure, at least one second tank is connected to the source of the second pressure, and the material is transported from the first tank (or from the first tank to the second tank (or second reservoirs). In addition, the system contains pressure reducer, which can be adjusted by the difference between the pressure in the first tank (or in the first tank and the pressure in the second tank (or second tanks).

In accordance with another aspect of the invention features the pen tool is viginia with the above system.

In accordance with the embodiment of the invention described above, the adaptive mode of transporting material is used on an aircraft.

When using the present invention, the noise level during transportation of the material can be reduced to such a level that the users, such as passengers of the aircraft, it is almost not feel it. Using the system and method in accordance with the invention, reducing noise, in particular on an aircraft is efficient from an economic point of view, and the weight increases slightly. In addition, by adapting the pressure difference and, accordingly, the speed of transportation, due to deceleration of the fluid kinetic energy of the transported material has less adverse effects on parts of the system. A special challenge is to ensure that the minimum weight of the aircraft.

For this purpose, in accordance with one embodiments of the invention in a pneumatic transport system uses a pressure reducer, with which the specified image may be regulated by the pressure difference in two tanks, in particular it can be reduced, the characteristics of the transportation can be changed sufficiently, in particular near the efficiency of the transportation can be reduced, resulting noise level is also reduced.

The air velocity at the starting point of receipt of the transported material largely depends on the position of the inlet tank to the piping system and the pressure in the tank-the collection. At the same time, the speed of the air determines the level of noise arising. By reducing the differential pressure level resulting noise can be substantially reduced.

Big difference between cabin pressure and ambient pressure at cruising altitude, which can cause fluid in the known systems moves with great speed, can be reduced so that the noise arising at the origin of the receipt of the transported material, is significantly reduced.

By reducing the speed of the fluid can effectively prevent accelerated wear of the parts of the system, in particular the walls of the inlet tank, because the kinetic energy of the transported material hits in the vessel wall, is reduced accordingly.

We can ensure that noise arising at the origin of the receipt of the transported material, and the kinetic energy of the material is reduced by modifying and adapting the pressure difference in the transport system.

Even the one embodiment of the invention the pressure reducer comprises at least one ventilation element between the first reservoir and the second source of pressure. The result is the ability to maintain constant the pressure difference or to compensate for excessive pressure difference so that the pressure in the second tank was increased. Such ventilation element can be regulated or unregulated. In addition, the ventilation element may contain devices reduce noise, such as sound-absorbing devices which reduce noise in the cabin at the origin of the receipt of the transported material. The ventilation element may be installed between the second reservoir and a second source of pressure and can be controlled in such a way that the conveyed material can be returned from the source of the second back pressure in the second tank.

In another embodiment, the pressure reducer contains between the first reservoir and a source of a second pressure at least one throttling element, which may be regulated or unregulated. A throttling element can be adjusted, namely to reduce the speed of the fluid flow, and can be installed between the vent member and a second source of pressure to reduce the flow velocity at this point. Alternatively, the throttling element can be installed between the second reserve is the Varos and source of the second pressure reduction speed with which the fluid flow out into the surrounding space.

In one embodiment, the proposed invention the system includes a compressor between the source of the second pressure and the second reservoir to provide negative pressure in the second tank, so that in case of high level of the second pressure still is ensured by the pressure difference between the first and second tanks due to the fact that the pressure in the second tank can be reduced. In addition to the compressor in parallel branches may be established regulated or unregulated throttling element in such a way as not to affect the operation of the compressor by reducing the pressure difference, that is, without creating a throttling effect.

In another embodiment of the invention in the connecting line between the source of the second pressure and the second tank is set back or shut-off valve to prevent the flow of fluid from a source of the second pressure in the second tank. The check valve can also be installed in parallel to the compressor and, in addition, it may contain a built-in throttling device.

In another embodiment of the invention between the second reservoir and the pressure source is set to a separator for separating the protractor the constituent material from the fluid. In another illustrative embodiment of the invention, the first tank is connected to the connecting line by means of the control valve, the actuation of which causes the beginning of the transportation of the material or to the termination of such transport.

In another embodiment, the invention devices are used to reduce the noise level, in particular they are installed on the first tank.

In another embodiment of the invention in the second tank is installed input safety device to reduce the kinetic energy of the transported material when it entered into the second tank.

In another embodiment of the invention the pressure reducer contains between the second reservoir and a source of a second pressure of at least one element, which combines the functions of throttling and ventilation.

In accordance with the embodiment of the invention in an emergency vent closed essentially without the use of additional energy, and/or throttling elements appear also essentially without the use of additional energy.

In accordance with yet another option proposed in the invention, a method for controlling a ventilation device and/or throttling ale is ntom as the control parameter is the pressure difference in the first and second tanks. Control parameter for controlling ventilation device and/or a throttling element can be set depending on the relative position of the first tanks and/or second reservoirs.

In accordance with another variant of the method the compressor and ventilation element can change and set the pressure offset in time prior to the transport of material, and after its completion.

In accordance with one variant of the method for the control and regulation of the ventilation element and/or throttling elements can be used information obtained from the sensors: for example, cabin pressure, the ambient pressure, the pressure in the second tank and the level of filling, the flight altitude or temperature. Such information also enables the diagnosis of the vacuum system. For example, when performing the operation of waste disposal, which uses only air, by measuring the resulting pressure gradient, it is possible to carry out a comparison of the required values of the pressure difference with the actual values, and, thus, can be quickly and reliably detected any irregularities in the system.

The described system and method provide an effective reduction of the noise level associated with the transportation of the material, so the level of comfort (for example, p is Shagirov) is significantly increased. Kinetic energy can best be maintained by regulating the pressure difference, resulting in possible to prevent or reduce wear on the system and the level of noise arising from its work. In addition, this system has a very light weight and economical to manufacture.

In accordance with the invention by means of move can be, for example, aircraft, railway wagon, truck, passenger vehicle, trailer, boat, ship or airship.

DETAILED description of the INVENTION

Fig is re 1 is a diagram of the vacuum system of the aircraft with a pressurized cabin.

As shown in figure 1, the first 3 tanks intended for the reception of material 2, which must be transported, connected through control valves 4 to the connecting line 5 leading to the second (Central) tank 7. At the entrance to the second tank 7 has a special safety input device 6, which among other things is intended to reduce the kinetic energy of the transported material 2 to prevent the second tank 7. With the help of another connecting line And reservoir-collection of 7 is connected through the separator 10, which contains a reservoir for return of the transported material, and through the compressor 12 with a source 14 of the second pressure, which is the environment surrounding the aircraft. In parallel with the compressor 12 and check valve 13.

If the pressure difference between the first source pressure (pressure at the starting point 3 of receipt of material that must be transported, for example, the pressure in the cabin) and a second source of pressure, namely the difference between cabin pressure and ambient pressure 14 is insufficient, the system works by using the compressor 12 (operating mode (I). In such an arrangement, the compressor 12 is activated at the latest at the moment when you want to perform the delete operation, waste is impressive. For a few seconds before opening the control valve 4 in the second tank 7 is already a negative pressure is generated. Thus, as soon as the valve opens 4 waste disposal begins transporting material 2 in the tank collection. The compressor 12 continues to operate until at least until the control valve 4 is closed again, and, thus, the tank 7 is maintained negative pressure to ensure the continuous transport of the material. The separator 10 prevents the ejection of the material 2 from the tank-collector 7, and thus protects the compressor 12 and the environment 14 from contamination. In this operating mode, the check valve 13 remains closed.

In an alternative operating mode II, with a sufficient difference between the pressure in the cabin 1 and the ambient pressure compressor 14 12 remains off. When the control valves 4 are closed, the tank 7 is installed low ambient pressure 14 overboard the aircraft. If the valves 4 waste management open, then in the reservoir 7 is supported by the negative pressure so that air flows through the check valve 13.

Thus, the compressor 12 for the most part are designed to provide the necessary transport mode, when the aircraft is on the ground. Reverse cleanout to be fully opened when the small pressure difference, and the air flow passes through it with minimal pressure drop. Then the stream for the separator 10 is installed unregulated throttling device 15 to provide a simple adaptation of the mode of transportation. However, generally speaking, the position of the throttling device may not be considered optimal for all applications, because of the difference of pressure created at great expense, is lost when the compressor 12.

The figure 2 shows a diagram of another system for noise reduction in the initial points of receipt 2, which must be transported, which is a limitation of the current differential pressure value, which is necessary for the operation of waste disposal, preferably in the operating mode II.

For reliable operation this design should provide the necessary features without using the compressor. It provides sufficient possibilities for reducing noise at cruising altitude, which usually occurs a sufficient pressure difference. This is true in most cases for most vacuum systems used on aircraft.

It is essential that the volume of air 9 in the tank-the collector 7 is such that when the operation of waste disposal in the second container 7 occurs unsustainable is anavissos the pressure gradient. Thus, most of the time the pressure in the tank-a collection of 7 increases until, until it reaches a steady state. This pressure increase is determined by the pressure drop between the volume 9 and the environment 14 in the steady state. The difference between cabin pressure 1 and pressure in the tank-a collection of 7 causes the respective time gradient of the input air flow rate and, therefore, noise occurring in the first tank 3.

In order to limit the resulting noise, it is necessary to provide a virtually constant pressure difference between cabin 1 and reservoir-collection 7. Generally speaking, additional vent valves 16a-16d (see figure 2) can perform this task prior to the operation of waste disposal, in the process of its execution and after execution of this operation. However, this may be due to high velocities or large volume costs between the connecting lines 5 or 11 or reservoir 7 and the vent valves 16a-16d. This can be compensated for by using an adjustable throttle valve 17A 17A or below the flow for ventilation valves 16a-16d. If the throttle valve 15, 17 used alone, its action is limited by the duration of vypolneniyasvoey waste removal.

The greater the volume of air 9 in the tank, the stronger the effect of the initial pressure in the tank at the waste removal process. In this case, the stationary regime is established for a relatively long time after the opening of the valve 4 (see figure 3). Thus, in this case, ventilation is crucial.

In those cases, when using the tank 7 is small, the volume of air 9 has a small value. Thus, it is possible to abandon the vent valves 16a-16d. In the case of a small number of foster reservoir 3 installed about the same distance from the tank 7, you can also use unregulated throttling element, for example, in the position 15b. In this position of the throttling element, the pressure drop does not affect the operation of the compressor 12. The reduction characteristics of the transported material 2 at low flight altitudes, i.e. at small differences of pressure, without the use of compressor 12 can also be compensated for by increased operating time of the compressor, if such a need arises. In addition, the use of the system in this border area is not a typical application.

In principle, the control valve 16 can be installed in positions 16A-16d. Immediately after a request to perform an operation to withdraw the Deposit of waste specified control valve 16 to set the tank pressure before as will open the valve 4 waste disposal. This procedure can be thought of as the opposite stage pumping air when the compressor 12. Then, for example, a throttle valve in position 17A or 17b maintains a constant pressure in the tank during the operation of waste disposal.

Since the pressure drop between cabin 1 and volume 9 depends on the length of the connecting line 5 and the pressure gradient in it, then the pressure difference that you want to install depends on the location of the first tank 3. Thus, various modes of transportation for foster tanks 3, located at different distances from the tank-collector 7, which is a typical case can be brought to the same modes.

In case of failure of the ventilation valve 16 must be completely closed, while an adjustable throttle valve 17 must be fully open, and their activation is carried out without the consumption of auxiliary energy. Thus, the system remains operational.

Also of interest are a combination of functions of ventilation and throttling element positions 16d and 17A.

As for control, the systems of the aircraft already has access to the necessary information, such as, for example, cabin pressure, pressure the e environment and the fill level of the tank-the album (to determine the volume of air in the tank). In addition, the determination of the filling level based on measurements of two absolute pressure sensors, directly provides information about the pressure in the tank 7. Thus, the use of additional sensors can be minimized through the use of necessary connections in the system.

On the basis of the values of deviations of the controlled parameter for the operation of waste disposal, which uses only air, you can get information about the possible clogging of pipelines in areas 1-9 and 9-14. The diagnostic function can also be implemented in known vacuum systems.
