Description

Technical Field

[0001] This utility model relates to the field of rainwater and sewage separation technology, specifically a rainwater and sewage separation device for drainage pipe networks. Background Technology

[0002] Rainwater and sewage separation is a drainage system that separates rainwater and sewage, each transported through its own pipeline for discharge or subsequent treatment. Rainwater is discharged directly into rivers through a rainwater pipe network, while sewage is collected through a sewage pipe network and sent to a sewage treatment plant for treatment. This avoids sewage from directly entering rivers and causing pollution. Furthermore, the collection, utilization, and centralized management of rainwater discharge can reduce the impact of water volume on sewage treatment plants and ensure their treatment efficiency.

[0003] In existing drainage pipe network rainwater and sewage separation devices, rainwater and sewage are transported separately using separate pipes. Sewage is treated by sewage treatment plants to meet discharge standards and then discharged in an orderly manner. The purified sewage is no longer polluting and is discharged through separate pipes. The required pipes are long and consume a lot of pipe materials to connect the sewage treatment plant and the river drainage point. In order to shorten the distance required for purified domestic water to be discharged into the river, a drainage pipe network rainwater and sewage separation device is proposed. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a drainage network rainwater and sewage separation device to solve the technical problem that existing drainage network rainwater and sewage separation devices require long pipes and consume a lot of pipe materials when discharging purified domestic sewage separately.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rainwater and sewage separation device for a drainage network, comprising a device body, a sewage pipe, and a clean water conduit. The top of the device body is a rainwater inlet, and the bottom of the device body is a rainwater outlet. A main drainage pipe is provided at the bottom of the device body. A clean water inlet is provided at one end of the clean water conduit, and a clean water outlet is provided at the other end. A one-way flow guiding mechanism is provided at the clean water outlet. The one-way flow guiding mechanism includes a baffle and a shield. A torsion shaft is provided on one side of the baffle, and a lower opening is provided at the bottom of the shield.

[0006] By adopting the above technical solutions, in order to ensure that rainwater can be discharged well during the rainy season and to avoid rainwater accumulating on the road surface and affecting traffic when the rainfall is heavy, the city and the vicinity of the sewage treatment plant have a rich network of rainwater drainage pipes. The clean water pipes can be connected to the nearest rainwater drainage pipes, and the rainwater will be collected and discharged into the nearest main drainage pipe and then into the river.

[0007] Furthermore, one end of the sewage pipe is a sewage inlet, and the other end of the sewage pipe is a sewage outlet. The sewage inlet is connected to the residential water drainage pipeline, and the sewage outlet is connected to the input end of the sewage treatment plant.

[0008] By adopting the above technical solution, after domestic sewage is generated, it will enter the sewage pipe through the sewage inlet and then enter the sewage treatment plant through the sewage outlet at the other end of the sewage pipe.

[0009] Furthermore, the purified water inlet is connected to the output end of the sewage treatment plant, and the purified water outlet opens on one side of the interior of the device body.

[0010] By adopting the above technical solution, after domestic sewage is purified by the sewage treatment plant, the clean water, which is no longer polluting, will enter the clean water pipe from the output end of the sewage treatment plant through the clean water inlet.

[0011] Furthermore, both the rainwater outlet and the lower opening are connected to the main drainage pipe.

[0012] By adopting the above technical solution, the rainwater outlet and the lower opening are kept connected to the main drainage pipe, so that rainwater can enter the main flow section of the drainage pipe through the rainwater outlet and clean water through the lower opening.

[0013] Furthermore, the baffle is a circular plate structure, and the baffle is rotatably connected to one end of the water purification pipe via a torsion shaft.

[0014] By adopting the above technical solution, the prototype plate-shaped baffle can effectively block the circular water purification outlet and prevent rainwater backflow.

[0015] Furthermore, the baffle abuts against the purified water outlet, and the diameter of the baffle is larger than the diameter of the purified water outlet.

[0016] By adopting the above technical solution, the baffle effectively blocks the clean water outlet, preventing rainwater from overflowing the baffle and entering the clean water outlet when the main drain pipe is full.

[0017] Furthermore, the top of the shield is provided with a first inclined portion and a second inclined portion, and a screen is provided at the rainwater inlet.

[0018] By adopting the above technical solution, both the first inclined part and the second inclined part can provide a guiding effect for rainwater and small impurities, so that when the rainwater passes through the shield, it can flow smoothly downwards and together with the sewage pipe at the top of the shield, reduce the possibility of impurities and rainwater coming into contact with the connection between the shield and the main body of the device.

[0019] Furthermore, the first inclined portion is located on the top side of the second inclined portion, and the slope of the first inclined portion is less than the slope of the second inclined portion.

[0020] By adopting the above technical solution, the slope of the first inclined part is small, which provides a certain guiding effect for rainwater and small impurities while avoiding the first inclined part occupying a large vertical space.

[0021] Furthermore, the screen is adapted to the rainwater inlet and is movably connected to the main body of the device.

[0022] By adopting the above technical solution, the screen and the rainwater inlet have a high degree of compatibility, which allows the screen to be installed well at the rainwater inlet and avoids large gaps between the screen and the inner wall of the device.

[0023] Furthermore, one end of the sewage pipe extends into the interior of the device body, and the end of the sewage pipe extending into the interior of the device body is located at the top of the shield.

[0024] By adopting the above technical solution, domestic sewage and rainwater are separated inside the main body of the device through sewage pipes. This not only prevents domestic sewage from polluting rainwater, but also prevents rainwater from entering the sewage treatment plant along with domestic sewage, thus reducing the workload of the sewage treatment plant.

[0025] In summary, the present invention has the following main advantages:

[0026] 1. This utility model, by setting up a water purification conduit, a main drain pipe, a torque shaft, and a baffle, ensures smooth drainage during the rainy season. Cities and areas near sewage treatment plants require a large number of rainwater drainage pipes. After domestic sewage is purified, it is introduced into the nearest main drain pipe through the water purification conduit, eliminating the need to lay separate pipes for discharge. This shortens the distance for harmlessly treated domestic sewage to be discharged into rivers. At the same time, when the main drain pipe is full due to heavy rainfall, the torque shaft and baffle can prevent rainwater from flowing back into the water purification conduit.

[0027] 2. This utility model, by setting up a shield, a first inclined part, a second inclined part, and a screen, uses the screen to intercept plastic bags, leaves, and other garbage on urban roads at the rainwater inlet, preventing them from entering the river with the rainwater. However, small impurities such as mud still exist. During the rainy season, when rainwater flows downward along the main body of the device, the shield can prevent small impurities from reaching the torque shaft and baffle, thus affecting its normal use. The setting of the first and second inclined parts can prevent small impurities and a small amount of rainwater from accumulating on the top of the shield. Attached Figure Description

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1:

[0036] A drainage network rainwater and sewage separation device, such as Figures 1-4 As shown, the device includes a main body 1, a sewage pipe 2, and a clean water conduit 3. The top of the main body 1 is a rainwater inlet 5, and the bottom is a rainwater outlet 6. A main drain pipe 4 is located at the bottom of the main body 1. One end of the clean water conduit 3 has a clean water inlet 7, and the other end has a clean water outlet 8. A one-way flow guide mechanism 11 is located at the clean water outlet 8. The one-way flow guide mechanism 11 includes a baffle 111 and a shield 112. A torque shaft 110 is located on one side of the baffle 111, and the bottom of the shield 112 has an opening... With a bottom opening 115, to ensure that rainwater can be discharged well during the rainy season and to avoid rainwater accumulating on the road surface and affecting traffic when there is heavy rainfall, the city and the vicinity of the sewage treatment plant have a rich network of rainwater drainage pipes. The purified water pipe 3 can be connected to the nearest rainwater drainage pipe and collected with the rainwater into the nearest main drainage pipe 4, which is then discharged into the river. There is no need to lay a separate discharge pipe to discharge the purified water. At the same time, when the purified water pipe 3 is connected to the main body 1 of the device, the one-way flow guide mechanism 11 is used to prevent rainwater from flowing back into the purified water pipe 3.

[0037] See Figure 1 , Figure 3One end of the sewage pipe 2 is the sewage inlet 9, and the other end is the sewage outlet 10. The sewage inlet 9 is connected to the residential water drainage pipe, and the sewage outlet 10 is connected to the input end of the sewage treatment plant. After the domestic sewage is generated, it will enter the sewage pipe 2 through the sewage inlet 9 and then enter the input end of the sewage treatment plant through the sewage outlet 10 at the other end of the sewage pipe 2. Then it will be purified in the sewage treatment plant to avoid the direct discharge of domestic sewage and pollution of the river.

[0038] See Figure 1 , Figure 3 The purified water inlet 7 is connected to the output end of the sewage treatment plant, and the purified water outlet 8 opens inside the main body 1 of the device. After the domestic sewage is purified by the sewage treatment plant, the purified water, which is no longer polluting, will enter the purified water conduit 3 through the purified water inlet 7 from the output end of the sewage treatment plant, and then enter the one-way flow guide mechanism 11 inside the main body 1 through the purified water outlet 8 at the other end of the purified water conduit 3. Finally, it will flow into the main drain pipe 4 through the lower opening 115 and be guided to the nearby river for discharge through the nearest drain pipe.

[0039] See Figure 2 , Figure 3 Both the rainwater outlet 6 and the lower opening 115 are connected to the main drainage pipe 4. The rainwater outlet 6 is kept connected to the main drainage pipe 4, so that rainwater can enter the main flow of the drainage pipe through the rainwater outlet 6. The lower opening 115 is kept connected to the main drainage pipe 4, so that the clean water discharged from the clean water outlet 8 can enter the main drainage pipe 4 through this point. As the main flow of the drainage pipe, the main drainage pipe 4 can merge the water flow of each branch and discharge it in a unified manner.

[0040] See Figure 3 , Figure 4 The baffle 111 is a circular plate structure. The baffle 111 is rotatably connected to one end of the water purification pipe 3 via a torsion shaft 110. The baffle 111, with its prototype plate structure, can effectively block the circular water purification outlet 8 to prevent rainwater backflow. The baffle 111 is rotatably connected to the water purification pipe 3 via the torsion shaft 110, so that when the purified water is discharged, the water flow impacts the baffle 111 and it can automatically rotate and open. After the batch of purified water is discharged, when there is no water flow impact at the baffle 111, the torsion shaft 110 will drive the baffle 111 to automatically close.

[0041] See Figure 3 , Figure 4 The baffle 111 abuts against the clean water outlet 8, and the diameter of the baffle 111 is larger than the diameter of the clean water outlet 8. The baffle 111 effectively blocks the clean water outlet 8, which can prevent rainwater from passing over the baffle 111 and entering the clean water outlet 8 when the main drain pipe 4 is full. The difference between the diameter of the baffle 111 and the diameter of the clean water outlet 8 effectively ensures the one-way interception effect of the baffle 111.

[0042] Example 2:

[0043] See Figure 1 , Figure 3 , Figure 4 The top of the shield 112 is provided with a first inclined part 113 and a second inclined part 114, and a screen 12 is provided at the rainwater inlet 5. The first inclined part 113 and the second inclined part 114 can provide a guiding effect for rainwater and small impurities, so that when the rainwater passes through the shield 112, it can flow smoothly downward. Together with the sewage pipe 2 at the top of the shield 112, it reduces the possibility of impurities and rainwater contacting the connection between the shield 112 and the main body 1. The screen 12 can intercept larger impurities such as leaves and plastic packaging left on urban roads, preventing them from entering the interior of the main body 1 and causing blockage, or being discharged into rivers and causing pollution.

[0044] See Figure 3 , Figure 4 The first inclined portion 113 is located on the top side of the second inclined portion 114. The slope of the first inclined portion 113 is smaller than that of the second inclined portion 114. The smaller slope of the first inclined portion 113 provides a certain guiding effect for rainwater and small impurities, while avoiding the first inclined portion 113 occupying a large vertical space and improving the utilization rate of space. The second inclined portion 114 is close to the outside, making it easier to contact rainwater and small impurities. Moreover, there is enough space in the vertical direction, so a larger slope can be set.

[0045] See Figure 1 , Figure 3 The screen 12 is adapted to the rainwater inlet 5 and is movably connected to the main body 1 of the device. The high compatibility between the screen 12 and the rainwater inlet 5 allows the screen 12 to be installed well at the rainwater inlet 5, avoiding large gaps between the screen 12 and the inner wall of the main body 1, which would affect the filtration effect. At the same time, the movable connection of the screen 12 ensures its disassembly, making it convenient for cleaning and maintenance.

[0046] See Figure 3 One end of the sewage pipe 2 extends into the interior of the main body 1 of the device, and the end of the sewage pipe 2 extending into the interior of the main body 1 is located at the top of the shield 112. The sewage pipe 2 separates domestic sewage and rainwater inside the main body 1, which can prevent domestic sewage from polluting rainwater and prevent rainwater from entering the sewage treatment plant with domestic sewage, thus reducing the workload of the sewage treatment plant. The sewage pipe 2 is located at the top of the shield 112, which can largely prevent rainwater and small impurities from contacting the gap at the connection between the shield 112 and the main body 1, thereby providing a certain degree of protection for the connection between the two.

[0047] The implementation principle of this utility model is as follows: First, domestic sewage enters sewage pipe 2 through sewage inlet 9. After being guided by sewage pipe 2, it enters the sewage treatment plant through sewage outlet 10 for purification treatment. The treated water enters the purified water conduit 3 through purified water inlet 7. After being guided by purified water conduit 3, it reaches purified water outlet 8. The purified water impacts the baffle 111 at purified water outlet 8. The baffle 111 is subjected to force and rotates along the torsion shaft 110 to open. The purified water enters the main drainage pipe 4 through the lower opening 115 at the bottom of the shield 112 and is discharged into the river through the main drainage pipe 4. When the batch of purified water is discharged, the torsion shaft 110 returns to its original position. The baffle 111 re-seals the purified water outlet 8; secondly, during the rainy season, large impurities in the rainwater are intercepted by the screen 12 at the rainwater inlet 5 and enter the interior of the main body 1 of the device, flowing downwards. Small impurities in the rainwater, when they come into contact with the shield 112, are guided by the first inclined part 113 and the second inclined part 114 and enter the main drainage pipe 4 through the rainwater outlet 6, from which they are discharged into the river; finally, when the amount of rainwater is large, and the main drainage pipe 4 is full or even overflows upwards to a certain extent, the rainwater entering the interior of the shield 112 from the lower opening 115 is blocked by the baffle 111 and cannot flow back into the purified water conduit 3.

[0048] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.
