Description

Technical Field

[0001] The utility model relates to the technical field of drainage of sanitary equipment, in particular to a train grey water recycling system. Background Art

[0002] The toilet in a passenger car is an indispensable and important facility to ensure the sanitation and convenience of passengers during long journeys. With the development of railway passenger transportation, the design requirements of the toilet collection system are constantly improving, requiring a reasonable system, reliable structure, high integration, reasonable functions, and easy use and maintenance. In addition, the railway passenger car toilet collection system needs to save the consumption of flushing water as much as possible, while the amount of water allocated to the toilet collection system by the railway passenger car water supply system is extremely limited, and the water supply has been in a decreasing trend. In order to meet the requirements of this trend, it is necessary to reuse the gray water generated by railway passenger cars to provide it to the toilet collection system as flushing water.

[0003] The EMU grey water recycling system is mainly composed of control module, pressure grey water unit, toilet, sewage valve, ejector, human-machine interface device, etc. By using the compressed air, power supply, water source, etc. provided by the vehicle, the grey water from the washbasin of the vehicle toilet is collected and reused to flush the toilet during operation, and the grey water is transferred and collected, reused and flushed, and collected in the sewage tank, so as to achieve zero discharge of grey water and sewage from the vehicle, greatly reduce the impact of railway vehicles on the surrounding environment of the line, and effectively solve the problem of atomization and icing of grey water discharge when railway vehicles are running in low temperature environment.

[0004] The existing train grey water recycling system collects waste water from the washroom into a grey water tank through pipes when processing grey water, and then uses the grey water in the grey water tank for flushing the toilet, thereby reducing water consumption on the train. However, when the existing device collects grey water, the pipe connecting the washbasin and the grey water tank is prone to blockage, resulting in the continuous growth of bacteria. When the grey water is used for flushing, bacteria will grow in the toilet, causing the spread of germs. Utility Model Content

[0005] The purpose of the present application is to solve the problem that the pipe between the hand pool and the gray water tank of the existing device is easily blocked, causing the continuous growth of bacteria in the gray water tank. The present application provides a train gray water recycling system.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] The train grey water recycling system comprises a grey water tank, a grey water pipe is arranged on the grey water tank, a clean water pipe is fixedly connected to the grey water tank, a black water pipe is fixedly connected to the grey water tank, a black water pipe is fixedly connected to the black water tank, and an interception structure is arranged between the grey water tank and the grey water pipe.

[0008] By adopting the above technical scheme, when the device is used to reuse the gray water on the train, the waste water in the wash basin on the train is collected through the gray water pipe, and the impurities mixed therein are intercepted by the interception structure, and then the filtered waste water is injected into the gray water tank. When the toilet needs to be flushed, the clean water tank injects water into the gray water tank through the clean water pipe to replenish the gray water, and then the toilet is flushed with the gray water. When there is a lot of waste water in the gray water, the waste water is injected into the black water tank through the black water pipe, so that the gray water pipe is not easy to flow back into the wash basin, and the pipe connected to the gray water tank of the device is not easy to be blocked, causing the growth of bacteria, so that the gray water in the device is safer and healthier to use.

[0009] Furthermore, the interception structure includes a limit plate fixedly connected to the end of the gray water pipe, and an interception cage is fixedly connected to the limit plate, and the interception cage is adapted to the gray water tank.

[0010] By adopting the above technical solution, wastewater enters the interception cage through the gray water pipe, and then enters four relatively arranged interception plates, and objects such as hair and paper towels in the water flow are intercepted by the interception cage.

[0011] Furthermore, a fixing column is fixedly connected to the interception cage, an interception plate is rotatably connected to the fixing column, and a rubber sleeve is fixedly connected to the interception plate.

[0012] By adopting the above technical solution, larger solid waste will move along the gray water pipe to the interception plate, and the interception plate will grab the solid waste, and the rubber sleeve will enhance the interception efficiency of the interception plate for slippery objects.

[0013] Furthermore, a torsion spring is sleeved on the fixing column, and two ends of the torsion spring are respectively fixedly connected to the interception plate and the interception cage.

[0014] By adopting the above technical solution, the torsion spring reset drives the interception plate to rotate inward along the fixed column, thereby limiting the solid waste and making it easier to peel off the waste.

[0015] Furthermore, a limiting groove is provided on the limiting disk, a limiting plate is provided on the gray water tank, a limiting block is fixedly connected to the limiting plate, and the limiting block is adapted to the limiting groove.

[0016] By adopting the above technical solution, the limiting groove is adapted to the limiting block, which facilitates the installation of the gray water pipe and makes the device more convenient in the process of cleaning garbage.

[0017] Furthermore, a driving motor is fixedly connected to the gray water tank, a bidirectional threaded rod is fixedly connected to an output end of the driving motor, and the bidirectional threaded rod is rotatably connected to the gray water tank.

[0018] By adopting the above technical solution, the driving motor drives the bidirectional threaded rod to rotate, thereby driving a limit plate to move, so that the limit on the limit groove is released, making the device more convenient in the process of cleaning garbage. The ability to quickly clean garbage also limits the growth of bacteria in the device.

[0019] Furthermore, a guide column is fixedly connected to the gray water tank, and the guide column is slidably connected to the limit plate.

[0020] By adopting the above technical solution, the limiting plate moves along the fixed column, so that the limiting block is more stable when clamping the limiting groove.

[0021] Furthermore, a water diversion valve is fixedly connected to the grey water tank, a drainage pipe is fixedly connected to the water diversion valve, and a water outlet pipe is fixedly connected to the water diversion valve.

[0022] By adopting the above technical solution, when the gray water on the device is discharged, the discharged gray water is separated by the water diverter valve. When the gray water is stored too much or needs to be cleaned, the water diverter valve is activated to discharge the gray water into the drain pipe for discharge. When the gray water is needed for flushing, the water diverter valve is activated to discharge the gray water into the outlet pipe.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, when waste water from the wash basin flows into the grey water tank, the waste water enters the interception cage through the grey water pipe, and then enters four relatively arranged interception plates, and the hair, paper towels and other objects in the water flow are intercepted by the interception cage. At the same time, larger solid garbage will move toward the interception plate along the grey water pipe, and the interception plate will grab the solid garbage, and the interception plate will be driven to rotate inward along the fixed column by the torsion spring reset to limit the solid garbage, so that the garbage in the water flow is not easy to enter the grey water tank, and the garbage is not easy to be blocked in the pipe during the water discharge process of the grey water tank, thereby reducing the bacterial growth caused by garbage accumulation in the pipe, reducing the bacteria carried by the grey water during use, and making the use of grey water safer.

[0025] 2. In the present application, when it is necessary to clean the garbage of shoelaces in the wastewater, the driving motor is started to drive the bidirectional threaded rod to rotate, thereby driving the limit plates to move along the fixed column, so that the limit plates move in opposite directions to release the limit on the limit groove, and then the gray water pipe is lifted upward, the interception cage and the interception plate can be removed together, and the garbage in the interception cage and the interception plate can be cleaned manually, and finally the cleaned gray water pipe can be installed. At this time, the limit groove is adapted to the limit block, which facilitates the installation of the gray water pipe, making the device more convenient in the process of cleaning garbage. The ability to quickly clean garbage also limits the growth of bacteria in the device, thereby improving the convenience of using the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses a train grey water recycling system.

[0036] When the device is used to reuse gray water on the train, the waste water in the wash basin on the train is collected through the gray water pipe 3, and the impurities mixed therein are intercepted through the interception structure, and then the filtered waste water is injected into the gray water tank 1. When the toilet needs to be flushed, the clean water tank 2 injects water into the gray water tank 1 through the clean water pipe 5 to replenish the gray water, and then the toilet is flushed with the gray water. When there is a lot of waste water in the gray water, the waste water is injected into the black water tank 4 through the black water pipe 9, so that the gray water pipe 3 is not easy to flow back into the wash basin, and the pipeline connected to the gray water tank 1 of the device is not easy to be blocked, causing the growth of bacteria, making the gray water in the device safer and healthier to use.

[0037] Reference Figure 1 and Figure 2 , Figure 4 The interception structure includes a limit plate 10 fixedly connected to the end of the gray water pipe 3, and an interception cage 16 is fixedly connected to the limit plate 10, and the interception cage 16 is adapted to the gray water tank 1. A fixed column 18 is fixedly connected to the interception cage 16, and an interception plate 17 is rotatably connected to the fixed column 18, and a rubber sleeve 20 is fixedly connected to the interception plate 17.

[0038] When waste water from the wash basin flows into the grey water tank 1, the waste water enters the interception cage 16 through the grey water pipe 3, and then enters four relatively arranged interception plates 17, and the interception cage 16 intercepts objects such as hair and paper towels in the water flow. At the same time, larger solid garbage will move toward the interception plate 17 along the grey water pipe 3, and the interception plate 17 will grab the solid garbage, and the interception plate 17 will be driven to rotate inward along the fixed column 18 by the torsion spring 19 to limit the solid garbage, so that the garbage in the water flow is not easy to enter the grey water tank 1, and the garbage is not easy to be blocked in the pipe during the water discharge process of the grey water tank 1, thereby reducing the bacterial growth caused by the accumulation of garbage in the pipe, reducing the bacteria carried by the grey water during use, and making the use of the grey water safer.

[0039] Reference Figure 3 and Figure 5 A torsion spring 19 is sleeved on the fixed column 18, and the two ends of the torsion spring 19 are fixedly connected to the interception plate 17 and the interception cage 16 respectively. A limiting groove is provided on the limit plate 10, and a limiting plate 11 is provided on the gray water tank 1. A limiting block 12 is fixedly connected to the limiting plate 11, and the limiting block 12 is adapted to the limiting groove. A driving motor 15 is fixedly connected to the gray water tank 1, and a bidirectional threaded rod 14 is fixedly connected to the output end of the driving motor 15, and the bidirectional threaded rod 14 is rotatably connected to the gray water tank 1. A guide column 13 is fixedly connected to the gray water tank 1, and the guide column 13 is slidably connected to the limiting plate 11.

[0040] When it is necessary to clean the shoelace garbage in the wastewater, start the driving motor 15 to drive the bidirectional threaded rod 14 to rotate, thereby driving the limit plates 11 to move along the fixed column 18, and let the limit plates 11 move in opposite directions to release the limit on the limit groove, and then lift the gray water pipe 3 upward, so that the interception cage 16 and the interception plate 17 can be removed together, and the garbage in the interception cage 16 and the interception plate 17 can be cleaned manually, and finally the cleaned gray water pipe 3 is installed. At this time, the limit groove is adapted to the limit block 12, which facilitates the installation of the gray water pipe 3, making the device more convenient in the process of cleaning garbage. The ability to quickly clean garbage also limits the growth of bacteria in the device, thereby improving the convenience of the device when used.

[0041] Reference Figure 1 A water diversion valve 7 is fixedly connected to the gray water tank 1 , a drainage pipe 8 is fixedly connected to the water diversion valve 7 , and a water outlet pipe 6 is fixedly connected to the water diversion valve 7 .

[0042] When the gray water on the device is discharged, the discharged gray water is separated by the water diverter valve 7. When the gray water is stored too much or needs to be cleaned, the water diverter valve 7 is started to discharge the gray water into the drain pipe 8 for discharge. When the gray water is needed for flushing, the water diverter valve 7 is started to discharge the gray water into the outlet pipe 6.

[0043] Working principle: When the device is used to recycle gray water on the train, the waste water in the wash basin on the train is collected through the gray water pipe 3. When the toilet needs to be flushed, the clean water tank 2 injects water into the gray water tank 1 through the clean water pipe 5 to replenish the gray water, and then the toilet is flushed with the gray water. When there is a lot of waste water in the gray water, the waste water is injected into the black water tank 4 through the black water pipe 9, so that the water in the gray water pipe 3 is not easy to flow back into the wash basin;

[0044] When the waste water from the wash basin flows into the grey water tank 1, the waste water enters the interception cage 16 through the grey water pipe 3, and then enters the four interception plates 17 arranged opposite to each other, and the interception cage 16 intercepts the hair, paper towels and other objects in the water flow, and at the same time, the larger solid garbage moves toward the interception plate 17 along the grey water pipe 3, and the interception plate 17 grabs the solid garbage, and the interception plate 17 is driven to rotate inward along the fixed column 18 by the torsion spring 19 to limit the solid garbage, so that the garbage in the water flow is not easy to enter the grey water tank 1, and the garbage is not easy to be blocked in the pipe during the water discharge process of the grey water tank 1, which reduces the bacterial growth caused by the accumulation of garbage in the pipe, reduces the bacteria carried by the grey water during use, and makes the use of the grey water safer;

[0045] When it is necessary to clean the shoelace garbage in the wastewater, start the driving motor 15 to drive the bidirectional threaded rod 14 to rotate, thereby driving the limit plates 11 to move along the fixed column 18, and let the limit plates 11 move in opposite directions to release the limit on the limit groove, and then lift the gray water pipe 3 upward, so that the interception cage 16 and the interception plate 17 can be removed together, and the garbage in the interception cage 16 and the interception plate 17 can be cleaned manually, and finally the cleaned gray water pipe 3 is installed. At this time, the limit groove is adapted to the limit block 12, which facilitates the installation of the gray water pipe 3, making the device more convenient in the process of cleaning garbage. The ability to quickly clean garbage also limits the growth of bacteria in the device, thereby improving the convenience of the device when used.
