Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to a rainwater and sewage separation device for building vertical rainwater downpipes. Background Technology

[0002] To create a beautiful and livable environment, the nationwide rainwater diversion management initiative has entered a new phase. To better utilize rainwater resources, a separate municipal drainage system is being implemented for rainwater and sewage, effectively separating the two. Rainwater can be discharged directly into rivers through the rainwater pipe network, while sewage needs to be collected through the sewage pipe network and sent to sewage treatment plants for treatment. Only after the water quality meets standards is it discharged into rivers, thus preventing river pollution.

[0003] In the practice of rainwater and sewage separation projects, the phenomenon of mixed rainwater and sewage discharge in urban rainwater pipes is often encountered. The main reason is that the original rainwater drainage function of rainwater pipes has been changed by human beings. Some washing machine wastewater from balconies is directly discharged into rainwater pipes, some kitchen wastewater is directly connected to rainwater pipes, and some sewage of unknown purpose is directly discharged into rainwater pipes, which directly leads to the mixing of rainwater and sewage and makes it difficult to separate them clearly. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the original rainwater drainage function of rainwater pipes in the existing technology has been artificially changed, directly leading to the mixing of rainwater and sewage and making it difficult to separate them clearly. The proposed rainwater and sewage separation device for building vertical rainwater risers is to address this issue.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The design includes a vertical rainwater downpipe rainwater and sewage separation device, comprising an outer tank, with a top cover plate fixedly connected to the upper end of the outer tank. A rainwater collection port is provided on one side of the upper end of the top cover plate. A separator frame is connected inside the outer tank. Fixed shafts with return springs are rotatably connected to both sides of the separator frame. A bidirectional flow guide barrel is fixedly connected between the two fixed shafts with return springs. Tenons are fixedly connected to opposite sides of the bidirectional flow guide barrel. A float groove and a water distribution groove are provided between the separator frame and the outer tank. A water leakage grid is provided in the float groove. A float box is provided in the float groove. A float top plate is fixedly connected to the upper end of the float box. A flow guide hole is provided on the separator frame.

[0007] Preferably, a rainwater backup collection port is provided on the other side of the upper end of the upper cover plate.

[0008] Preferably, the rainwater collection port is connected to a connecting pipe, and one end of the connecting pipe is connected to a rainwater hopper.

[0009] Preferably, the outer barrel is coated with an anti-corrosion layer, which is a polypropylene anti-corrosion layer.

[0010] Preferably, a handle for adjusting the drain grid is connected to the outer barrel.

[0011] Preferably, the bottom end of the outer barrel is connected to a lower cover plate, one side of the bottom end of the lower cover plate is connected to a sewage drain pipe, and the other side of the bottom end of the lower cover plate is connected to a rainwater drain pipe.

[0012] Preferably, the bottom inner end of the lower cover plate is connected to a partition plate between the sewage drain pipe and the rainwater drain pipe.

[0013] Preferably, the partition frame is provided with a water inlet channel, the water inlet channel is connected to the water distribution channel, and the upper side of the floating body channel is provided with an overflow port.

[0014] The beneficial effects of the building vertical rainwater downpipe rainwater and sewage diversion device proposed in this utility model are as follows:

[0015] Rainwater enters the floating tank, causing the floating box to move the top plate of the floating body upwards. After the top plate moves upwards, it pushes the tenon, which in turn causes the bidirectional guide barrel to rotate around the fixed axis with a return spring towards the rainwater drain pipe, thus guiding the water flow towards the rainwater drain pipe. After the rain stops, the bidirectional guide barrel returns to its original position, pointing towards the sewage drain pipe, and collects the unknown water in the rainwater pipe again, guiding it into the sewage drain pipe. Rainwater and sewage are separated solely by the buoyancy of the water without the need for external power. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1: Refer to Figure 1-4 A building vertical rainwater downpipe rainwater and sewage separation device includes an outer tank 7, which is coated with an anti-corrosion layer of polypropylene. An upper cover 5 is fixedly connected to the upper end of the outer tank 7, and a rainwater drainage downpipe 3 is connected to the upper end of the upper cover 5. A rainwater collection port 6 is provided on one side of the upper end of the upper cover 5, and a spare rainwater collection port 4 is provided on the other side of the upper end of the upper cover 5. A connecting pipe 2 is connected to the rainwater collection port 6, and one end of the connecting pipe 2 is connected to a rainwater hopper 1. A lower cover 9 is connected to the bottom end of the outer tank 7, and a sewage drainage pipe 10 is connected to one side of the bottom end of the lower cover 9. A rainwater drainage pipe 11 is connected to the other side of the bottom end of the lower cover 9. A partition plate 19 is connected between the sewage drainage pipe 10 and the rainwater drainage pipe 11 at the bottom inner end of the lower cover 9. A partition frame 22 is connected inside the outer barrel 7. A fixed shaft 14 with a return spring is rotatably connected to both sides of the partition frame 22. A bidirectional flow guide barrel 12 is fixedly connected between the two fixed shafts 14 with return springs. A tenon 13 is fixedly connected to the opposite sides of the bidirectional flow guide barrel 12. A float groove 25 and a water distribution groove 21 are provided between the partition frame 22 and the outer barrel 7. A float groove guide hole 18 is opened on the partition frame 22. A water leakage grid 17 is provided inside the float groove 25. A handle 8 for adjusting the water leakage grid 17 is connected to the outer barrel 7. A float box 16 is provided inside the float groove 25. A float top plate 15 is fixedly connected to the upper end of the float box 16. A flow guide hole 20 is opened on the partition frame 22. The flow guide hole 20 connects the float groove 25 and the float groove guide hole 18.

[0023] Work process:

[0024] When it rains, rainwater is collected through the rainwater hopper 1 and enters the connecting pipe 2. The rainwater in the connecting pipe 2 flows into the water distribution trough 21 in the outer barrel 7. After being divided by the water distribution trough 21, the water flows through the guide hole 18 of the float trough and the drain grid 17 and then into the float trough 25. The drain grid 17 filters the impurities in the water. When the amount of rainwater that flows in reaches a certain amount, the buoyancy of the water causes the float box 16 to float up. The float box 16 causes the float top plate 15 to move upward. After the float top plate 15 moves upward, it pushes the protruding tenon 13 on the outside of the bidirectional flow guide barrel 12. After the protruding tenon 13 is pushed, it causes the bidirectional flow guide barrel 12 to rotate around the fixed shaft 14 with a return spring. This causes the fixed shaft 14 with the return spring to generate an elastic restoring force. After rotation, the upper end of the bidirectional flow guide barrel 12 rotates towards the rainwater drain pipe 11. The bidirectional flow guide barrel 12 covers the upper end of the sewage drain pipe 10, thereby guiding the water flow to the rainwater drain pipe 11.

[0025] After the rain stops, the rainwater in the float tank 25 slowly flows into the rainwater drain pipe 11 through the float tank guide hole 18. The float box 16, along with the float top plate 15, falls downwards. The bidirectional guide bucket 12 returns to the direction of the sewage drain pipe 10 under the elastic restoring force generated by the fixed shaft 14 with the return spring, and collects the unknown water in the rainwater pipe again and introduces it into the sewage drain pipe 10. Rainwater and sewage are separated by water buoyancy without the need for external power.

[0026] Example 2: When there is too much water in the floating tank 25 and it cannot be discharged in time, refer to... Figure 4 As another preferred embodiment of this utility model, the difference from embodiment 1 is that a water inlet trough 23 is provided on the partition frame 22, the water inlet trough 23 is connected to the water distribution trough 21, and an overflow port 24 is provided on the upper side of the float tank 25. The water in the water distribution trough 21 passes through the water inlet trough 23 and enters the float tank 25. When the liquid level in the float tank 25 is higher than the overflow port 24, the water is released from the overflow port 24.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
