Description

Technical Field

[0001] This invention relates to the field of train water suction technology, and in particular to a vacuum sewage unloading intelligent environmental protection interception device. Background Technology

[0002] Existing vacuum sewage discharge systems for railways employ a rotary pump vacuum negative pressure structure for suction or discharge. The sewage is directly collected through pipelines and passes through the vacuum sewage discharge host. The sewage may contain sharp or soft solid impurities such as cotton fabrics, metal screws, and coins that are difficult to pass through the vacuum rotary pump, which can easily cause blockages, entanglement, abnormal wear, etc., greatly affecting the service life of the host.

[0003] In summary, existing vacuum decontamination systems have drawbacks such as the presence of solid impurities that are difficult to pass through the vacuum rotor pump during suction or discharge. These impurities can easily cause blockages, entanglement, and abnormal wear in the vacuum rotor pump, which in turn greatly affects the service life of the main unit. Summary of the Invention

[0018] The present invention discloses a vacuum unloading intelligent environmental protection interception device.

Furthermore, solid impurities intercepted in the vacuum barrier box can fall directly into the transfer collection box through the cleaning and drain pipe. Finally, solid and liquid impurities in the transfer collection box can naturally fall into the septic tank by gravity. Therefore, this invention solves the problem of existing vacuum sludge removal systems where solid impurities are difficult to pass through the vacuum rotor pumps, easily causing blockage, entanglement, and abnormal wear, which greatly affects the service life of the main unit.

[0048] The tapered guide section 2-1-2 gradually tapers from top to bottom, allowing it to hold more solid impurities that are difficult to pass through vacuum rotor pump 3 and vacuum rotor pump 4 compared to the bottom of the flat surface. The staggered arrangement of the first sewage inlet and the second solid sewage outlet is to prevent solid impurities that are difficult to pass through vacuum rotor pump 3 and vacuum rotor pump 4 from directly accumulating at the second solid sewage outlet. The solid impurities that are difficult to pass through can gradually slide down the inner wall of the tapered guide section 2-1-2 to the second solid sewage outlet.

The water pipes are located above the four-sided interception net bag 2-3, and the multiple flushing holes on the water pipes are precisely aligned with the four-sided interception net bag 2-3.

[0050] The device features a simple structure and is easy to use. It allows for targeted rinsing of the four-sided interception net bags 2-3 by injecting tap water through the water inlet.

[0051] Reference Figures 5 to 7 Optionally, the transit central box 8 includes a transit central box body 8-1, a transit central box cover plate 8-2, a transit box interception net 8-3, a first connecting flange 8-4, a second connecting flange 8-5, and a third connecting flange 8-6;

The main body 8-1 of the transfer collection box is equipped with a first solid waste discharge outlet. A second connecting flange 8-5 is located at the first solid waste discharge outlet. An eighth electric knife gate valve 15 is installed on the second connecting flange 8-5. A third sewage inlet is located on the side of the lower part of the transfer collection box body 8-1. A third connecting flange 8-6 is located at the third sewage inlet and is connected to the cleaning and sewage discharge pipeline 7.

[0053] The No. 1 connecting flange 8-4 at the No. 1 sewage outlet is connected to the third negative pressure pipeline 17. The operation of the vacuum rotor pump No. 1 pump 3 / vacuum rotor pump No. 2 pump 4 generates negative pressure, which draws the liquid waste in the main body 8-1 of the transfer collection box into the vacuum rotor pump No. 1 pump 3 / vacuum rotor pump No. 2 pump 4, and directly into the septic tank 9 through the main sewage discharge pipeline 5. At the same time, solid waste that is difficult to pass through in the vacuum barrier box 2 enters the main body 8-1 of the transfer collection box in sequence through the cleaning sewage discharge pipeline 7 and the No. 3 sewage inlet. The interception net 8-3 of the transfer box is set to intercept solid waste from the No. 1 sewage outlet and then into the vacuum rotor pump No. 1 pump 3 / vacuum rotor pump No. 2 pump 4 when negative pressure is generated, thus avoiding the blockage of the vacuum rotor pump No. 1 pump 3 / vacuum rotor pump No. 2 pump 4.

[0056] Waste (a mixture of solid and liquid waste) enters the vacuum barrier box 2 through the main sewage inlet pipe 1. At this time, the No. 1 electric knife gate valve 10, the No. 2 electric knife gate valve 11, the No. 5 electric knife gate valve 14 and the No. 7 electric knife gate valve 22 are in the open state. Solid waste that is difficult to pass through is intercepted in the vacuum barrier box 2. The remaining solid waste and liquid waste enter the vacuum rotor pump No. 1 pump 3 and the vacuum rotor pump No. 2 pump 4 respectively and flow through the main sewage outlet pipe 5 and finally enter the septic tank 9.

[0057] Cleanup work:

[0058] During the cleaning operation of vacuum rotor pump No. 1 pump 3, close electric knife gate valves 10, 11, 13, 14, and 15, and open electric knife gate valves 12, 21, and 22. Vacuum rotor pump No. 1 pump 3 generates negative pressure, which draws liquid waste from the transfer collection box 2 into vacuum rotor pump No. 1 pump 3 through the third negative pressure pipeline 17 and the first negative pressure pipeline 6, and then directly into the septic tank 9 through the main sewage pipeline 5. At the same time, solid waste that is difficult to pass through in the vacuum barrier box 2 enters the main body 8-1 of the transfer collection box through the cleaning sewage pipeline 7 and the No. 3 sewage inlet.

[0059] During the cleaning operation of vacuum rotor pump No. 2 pump 4, close electric knife gate valves No. 10, No. 2, No. 3, No. 12, No. 5, No. 14, and No. 8, and open electric knife gate valves No. 4, No. 6, No. 21, and No. 7, No. 22. Vacuum rotor pump No. 2 pump 4 generates negative pressure, which draws the liquid waste in the transfer collection box 2 sequentially from the third negative pressure pipeline 17 and the second negative pressure pipeline 16 to vacuum rotor pump No. 1 pump 3 and directly into the septic tank 9 through the main sewage discharge pipeline 5. At the same time, solid waste that is difficult to pass through in the vacuum barrier box 2 sequentially enters the main body 8-1 of the transfer collection box through the cleaning sewage discharge pipeline 7 and the No. 3 sewage inlet.

[0060] The aforementioned vacuum rotor pump No. 1 pump 3 and vacuum rotor pump No. 2 pump 4 can be cleaned and operated simultaneously. When closed, electric knife gate valves No. 10, No. 2, No. 5, No. 14, and No. 8 are closed, while electric knife gate valves No. 3, No. 12, No. 4, No. 6, No. 21, and No. 7 are opened. Vacuum rotor pump No. 1 pump 3 and vacuum rotor pump No. 2 pump 4 generate negative pressure, which draws the liquid waste in the transfer collection box 2 to the third negative pressure pipeline 17, and then into the first negative pressure pipeline 6 and the second negative pressure pipeline 16, and then into vacuum rotor pump No. 1 pump 3 and vacuum rotor pump No. 2 pump 4, and finally directly into the septic tank 9 through the main sewage pipeline 5. At the same time, solid waste that is difficult to pass through in the vacuum barrier box 2 enters the main body 8-1 of the transfer collection box through the cleaning sewage pipeline 7 and the No. 3 sewage inlet.

[0061] When the waste in the main body 8-1 of the transfer collection box is full, the No. 8 electric knife gate valve 15 can be opened automatically, and the waste will fall directly into the septic tank 9 from the No. 1 solid waste discharge port in the main body 8-1 of the transfer collection box.

[0062] This device features automatic cleaning, centralized collection, and periodic discharge of solid waste. Its confined space is not affected by the internal pump room area, greatly reducing personnel operating costs and effectively extending the service life of the equipment. This device can also perform wheel-type start-up of the two working vacuum rotor pumps, No. 1 pump 3 and No. 2 pump 4, which effectively reduces the wear of the vacuum rotor pumps.

[0063] In summary, the present invention provides a vacuum unloading intelligent environmental protection interception device. Electric gate valves 10, 11, 14, and 21 are all installed on a vacuum barrier box 2. The main sewage inlet pipe 1 is installed on electric gate valve 14. Electric gate valve 10 is connected to vacuum rotor pump 3 via a T-connector, with electric gate valve 12 connected to the outside of the T-connector. Electric gate valve 11 is connected to vacuum rotor pump 4 via a T-connector, with electric gate valve 13 connected to the outside of the T-connector. Vacuum rotor pump 3 is connected to one end of the main sewage outlet pipe 5, and the other end of the main sewage outlet pipe 5 is connected to a septic tank 9. The pipe extending from one end of the main sewage outlet pipe 5 to the other end connects to a branch pipe on vacuum rotor pump 4. The system is connected in parallel with vacuum rotor pump 3 (pump 1) and vacuum rotor pump 4 (pump 2). A No. 7 electric knife gate valve 22 is installed on the main sewage discharge pipe 5 between the septic tank 9 and vacuum rotor pump 4. One end of the first negative pressure pipe 6 is installed on the No. 3 electric knife gate valve 12, and one end of the second negative pressure pipe 16 is installed on the No. 4 electric knife gate valve 13. The other ends of the first and second negative pressure pipes 6 and 16 intersect and are connected at the intersection by a No. 3 tee pipe. A third negative pressure pipe 17 is also installed on the No. 3 tee pipe, connecting to the transfer and centralizing box 8. One end of the cleaning and sewage discharge pipe 7 is installed on the No. 6 electric knife gate valve 21, and the other end is installed on the transfer and centralizing box 8. The transfer and centralizing box 8 is installed above the septic tank 9, and an No. 8 electric knife gate valve 15 is installed between the transfer and centralizing box 8 and the septic tank 9.

[0064] First, the vacuum barrier box 2 effectively intercepts solid impurities that are difficult to pass through the vacuum rotor pumps 3 and 4, while solid impurities and liquid contaminants that can pass through the vacuum rotor pumps 3 and 4 can directly enter them, thus reducing the likelihood of blockage. Second, the solid impurities intercepted in the vacuum barrier box 2 can fall directly into the transfer collection box 8 through the cleaning and drain pipe 7. Finally, the solid and liquid impurities in the transfer collection box 8 can fall naturally into the septic tank 9 by gravity. Therefore, this invention solves the problem of existing vacuum sludge removal systems where solid impurities that are difficult to pass through the vacuum rotor pumps easily cause blockage, entanglement, and abnormal wear, which greatly affects the service life of the main unit.
