Description

Technical Field

[0001] This utility model relates to the field of rainwater and sewage separation, and in particular to an anti-clogging rainwater and sewage separation pipe. Background Technology

[0002] Urban sewage mainly consists of domestic sewage and rainwater. Domestic sewage contains many solid greases, filth, and other substances that easily contaminate the inside of pipes, making it difficult to treat. Rainwater is relatively cleaner than sewage, but its volume is much larger. If sewage and rainwater cannot be initially separated at the source, their eventual mixing and subsequent environmental treatment will significantly increase costs.

[0003] Therefore, based on environmental protection considerations, during urban road construction, it is necessary to initially classify and separate the water collected on the ground of a street so that rainwater and domestic sewage can be treated with different environmentally friendly processes. Thus, it is necessary to distinguish between rainwater and urban sewage from the source.

[0004] Currently, rainwater and sewage separation is mainly achieved in end-of-pipe treatment equipment after mixing, such as the announcement number: CN213101128U, named: A rainwater and sewage separation device to prevent pipe blockage. This type of separation device is used to separate rainwater and sewage after they have been mixed. Utility Model Content

The swing center of the first baffle is located at its upper edge, and the swing edge of the first baffle is in contact with the sewage pipe under the tension of a first tension band. A second opening is provided on the inlet main pipe between the inlet of the inlet main pipe and the inlet of the sewage pipe. The second opening and the rainwater... The pipes are connected in a continuous manner; the inner wall of the main inlet pipe at the second opening is also provided with a second baffle that rotates and swings relative to the main inlet pipe; the swing center of the second baffle is located at the lower edge of the second baffle, and the swing edge of the second baffle contacts the main inlet pipe through the second tension band; the lower edge of the second baffle is also provided with rack-shaped pressure teeth facing the inside of the main inlet pipe; the pressure range for pulling open the first tension band is: the liquid level exceeds the upper edge of the first baffle and is lower than the lower edge of the second baffle; the pressure range for pulling open the second tension band is: the pressure of the water flow impacting the pressure teeth is greater than the tension of the second tension band.

[0007] Furthermore, the first tension band and the second tension band are structured as follows: a tension spring and a pull rod; the spring and the pull rod are connected.

[0008] Furthermore, the main inlet pipe, sewage pipe, and rainwater pipe together form a structure resembling the shape of a human.

[0009] Furthermore, the upper edge of the first baffle is hinged to the sewage pipe via a first pivot, and the opposite sides of the first baffle are connected to a fixing rod via a first tension band, the fixing rod being fixed to the upper surface of the sewage pipe.

[0010] Furthermore, the lower edge of the second baffle is hinged to the main water inlet pipe via the second pivot, and the upper edge of the second baffle is connected to the inner wall of the main water inlet pipe via the second tension band.

[0011] Furthermore, a spacer is fixed to the upper edge of the second baffle, and the two ends of the spacer are connected to the inner wall of the main water inlet pipe by two second tension bands.

[0012] Furthermore, the angle between the pressure tooth and the second baffle is an obtuse angle, which can be greater than 90 degrees and less than 180 degrees, with the best angle being 120 degrees.

[0019] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In this application, the swing edge and swing center are defined by the rotational swing of the first baffle 23 and the second baffle 32. The swing edge is the distal edge away from the rotation center, and the swing center is centered on the rotation axis of the baffle.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, in order to achieve the effect of roughly separating domestic sewage and rainwater generated during rainy days, a clog-resistant rainwater and sewage separation pipe is disclosed, including an inlet main pipe 1 for receiving rainwater or domestic sewage; the lower end of the inlet main pipe 1 is connected to a sewage pipe 2, forming an "L" shape; a first opening 20 for discharging sludge is provided on the short side of the "L" at the bottom of the sewage pipe 2, and the first opening 20 can also be provided in the bend area of ​​the "L" shape. When the inner wall of the sewage pipe 2 is blocked or obstructed by sludge, the blockage can be discharged from the first opening 20. The outer surface of the sewage pipe 2 where the first opening 20 is located is also provided with a first baffle 23 that rotates and swings relative to the sewage pipe 2; the swing center of the first baffle 23 is located at the upper edge of the first baffle 23, and the swing edge of the first baffle 23 is in contact with the sewage pipe 2 by the tension of the first tension band 22; specifically, the upper edge of the first baffle 23 is hinged to the sewage pipe 2 through the first rotating shaft 24, and the first baffle 23 as a whole can rotate about the first rotating shaft 24; the opposite sides of the first baffle 23 are connected to the fixing rod 21 through the first tension band 22, and the fixing rod 21 is fixed to the upper surface of the sewage pipe 2.

[0021] A second opening 30 is provided on the main water inlet pipe 1 between the inlet of the main water inlet pipe 1 and the inlet of the sewage pipe 2. The second opening 30 is connected to the rainwater pipe 3.

[0022] like Figure 2 As shown, the inner wall of the water inlet main pipe 1 at the second opening 30 is also provided with a second baffle 32 that rotates and swings relative to the water inlet main pipe 1; the swing center of the second baffle 32 is located at the lower edge of the second baffle 32, and the swing edge of the second baffle 32 contacts the water inlet main pipe 1 through the second tension band 34; the lower edge of the second baffle 32 is also provided with a rack-shaped pressure tooth 321 facing the inside of the water inlet main pipe 1; the angle between the pressure tooth 321 and the second baffle 32 is an obtuse angle, preferably an obtuse angle of 120 degrees.

[0023] The pressure range for pulling open the first tension band 22 is: the liquid level exceeds the upper edge of the first baffle 23 and is lower than the lower edge of the second baffle 32; that is... Figure 3The height range from H1 to H1+H2.

[0024] The pressure range for pulling the second tension band 34 is: the pressure of the water flow impact pressure tooth 321 is greater than the tension of the second tension band 34.

[0025] To explain the structure of the first tension band 22 and the second tension band 34 in more detail, the specific structure of the tension band can be a combination of a spring and a pull rod. For example, one end of the spring is connected to the pull rod, the other end of the spring is connected to the sewage pipe 2 or the main water inlet pipe 1, and the other end of the pull rod is connected to the baffle.

[0026] To better separate rainwater and domestic sewage and facilitate classification, it is best to do so as follows: Figure 1 As shown, the main inlet pipe 1, sewage pipe 2, and rainwater pipe 3 are arranged in a human-shaped structure. The rainwater pipe 3 and sewage pipe 2, which are on opposite sides, will not affect each other's discharge and treatment.

[0027] Working principle:

[0028] In this utility model, the main water inlet pipe 1 and the sewage pipe 2 are integrally formed. Since the tension threshold of the first tension band 22 is the height where the liquid level exceeds H1 but does not exceed H1+H2.

[0029] Because people's lives are mostly regular and cyclical, the flow of domestic sewage usually fluctuates dynamically within a certain range throughout the day, without sudden large-scale discharges. Therefore, it is assumed that the flow fluctuates dynamically within a certain range. When sewage pipe 2 is unobstructed, domestic sewage will flow directly into the dedicated domestic sewage pipe. When sewage pipe 2 is blocked by grease and dirt, the water level of domestic sewage will rise. Due to the force of gravity, the first baffle 23 will open, allowing the dirt to fall off.

[0030] During rainy days, the large flow of rainwater causes a sudden increase in the amount of water entering the main inlet pipe 1 and the sewage pipe 2, resulting in a larger overall water flow. The increased flow of water impacts the pressure tooth 321, causing the second baffle 32 to open at an angle. As the second baffle 32 opens, rainwater flows directly through it into the second opening 30. Initially, the rainwater entering the sewage pipe 2 helps to clean it. The greater the rainwater flow, the wider the opening angle of the second baffle 32, effectively preventing rainwater from entering the sewage pipe 2.

[0031] When the rain stops, the second tension band 34 will pull the second baffle 32 back and make it fit against the inner wall of the main water inlet pipe 1 again.

[0032] Another advantage of this utility model is that when oil or other dirt clogs the sewage pipe 2, some oil will stick to the surface of the first baffle 23. At this time, a long-handled scraper extending from the main water inlet pipe 1 can directly contact the surface of the first baffle 23 and directly remove the attached dirt physically.
