Technical Field

[0001] The invention belongs to the technical field of municipal pipe networks, and in particular relates to a sewage diversion pipe network. Background Art

[0002] The municipal sewage treatment network is an important project to maintain the smooth operation of the entire city. Before the sewage collected in the municipal sewage network enters the sewage treatment plant, it is usually necessary to divert the sewage. On the one hand, it reduces the processing burden of the sewage treatment plant, and on the other hand, it can slow down the flow rate of the sewage and allow the sewage to remain stationary.

[0003] According to the patent search publication number CN216238850U, a sewage diversion pipe network disclosed in the patent search publication number CN216238850U cuts and decomposes the falling sludge and other impurities through the inclined cutting blades, and the sewage storage net bag below has a good filtering effect on the sewage flowing out of the sewage discharge pipe, reducing the debris entrained in the sewage from entering the first diversion pipe and the second diversion pipe, reducing the probability of blockage of the first diversion pipe and the second diversion pipe, and playing an auxiliary sewage discharge and reducing the effect of blockage.

[0004] Therefore, before the sewage enters the sewage treatment plant through the diversion pipe network, the sewage can be initially filtered to streamline the treatment process of the sewage treatment plant, improve the treatment efficiency and reduce the cost of sewage treatment. However, in the above scheme, when the garbage is blocked by the filter and filtered out, the filter needs to be pulled out and cleaned as a whole, and the cleaning process is complicated and cumbersome. Summary of the invention

[0005] The present invention provides a sewage diversion pipe network to solve the problem that impurities formed by filtering in the diversion pipe are difficult to clean.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: A sewage diversion pipe network comprises a diversion pipe, wherein the diversion pipe comprises a transverse section and a vertical section which are interconnected, a sieve plate is obliquely fixed in the vertical section, and a first water filtering hole is formed on the sieve plate; The side wall of the vertical section is connected with an inclined sewage discharge pipe, and the screen plate and the bottom wall of the inclined sewage discharge pipe are coplanar. Furthermore, a portion of the bottom wall of the sewage discharge inclined pipe is provided with second water filtering holes, and the bottom wall of the sewage discharge inclined pipe is connected to a recovery pipe, one end of the recovery pipe is connected to all the second water filtering holes, and the other end is connected to the side wall of the vertical section.

[0007] Furthermore, the transverse section and the vertical section are both square pipes.

[0008] Furthermore, a guide plate is installed on the inner wall of the vertical pipe, one end of the guide plate is rotatably installed on the side wall of the vertical section connected to the sewage inclined pipe, and the other end is inclined toward the relative side wall of the vertical section, and the free end of the guide plate is located above the screen plate.

[0009] Furthermore, a first elastic member capable of being compressed is installed between the rotating end of the guide plate and the inner wall of the vertical section.

[0010] Furthermore, a through hole is opened on the side wall of the vertical section, the inclined sewage discharge pipe is connected to the through hole, and a splash plate is connected to the side wall above the through hole, and the splash plate partially blocks the through hole.

[0011] Furthermore, the splash plate is rotatably connected to the inner wall of the sewage discharge inclined pipe, and a second elastic member is provided between the rotating end of the splash plate and the side wall of the sewage discharge inclined pipe.

[0012] Furthermore, it also includes a main pipeline, the end of which is connected to a transfer pool, and the periphery of the transfer pool is connected to multiple branch pipes.

[0013] Furthermore, a conical guide surface is provided on the bottom wall of the transfer tank, and the bottom end of the conical guide surface is smoothly connected to the bottom wall of the diversion pipe.

[0014] Furthermore, one end of the vertical section away from the horizontal section is connected to a buffer section, the buffer section is horizontally arranged, and the end of the buffer section is used to be connected to a sewage treatment device.

[0015] The present invention can achieve the following beneficial effects: 1. The present application arranges an inclined sewage pipe obliquely on the side wall of the diverter pipe, and fixes a sieve plate with a first water filter hole in the vertical section, so that when the sewage is discharged to the sewage treatment plant, the larger solid waste in the sewage is first preliminarily filtered through the sieve plate; after the sewage passes through the sieve plate, the solid waste is retained on the sieve plate and slides along the inclined sieve plate to be discharged to the inclined sewage pipe, and the water in the sewage is discharged downward to the sewage treatment plant through the first filter hole; the diverter pipe design structure of the present application enables the sewage to filter solid pollutants, and the filter structure does not need to be frequently cleaned and maintained under the flushing of sewage; in addition, the staff can also reach into the inclined sewage pipe from the end of the inclined sewage pipe to scrape the side wall and sieve plate of the inclined sewage pipe to achieve cleaning and maintenance of the filter structure.

[0016] 2. Setting a guide plate, opening a second water filter hole on the bottom wall of the sewage inclined pipe, and setting a recovery pipe between the sewage inclined pipe and the vertical section can extend the flow path of the sewage, so that the sewage can be discharged as much as possible into the vertical section below the screen plate and flow to the sewage treatment plant along the diversion pipe.

[0017] 3. A transfer tank is set up between the main pipe and the diversion pipe so that the sewage in the main pipe can be diverted to each diversion pipe, thereby reducing the sewage flow in the diversion pipe and reducing the situation where the sewage is discharged along the inclined sewage pipe due to the large sewage flow in the diversion pipe.

[0020] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0021] like Figure 1 and Figure 2 As shown, a sewage diversion pipe network includes a main pipe 1 connected to a municipal sewage pipe network, the outlet end of the main pipe 1 is connected to a transfer tank 2, and the periphery of the transfer tank 2 is connected to multiple diversion pipes 3. Sewage is discharged from the main pipe 1 into the transfer tank 2, and after being gathered in the transfer tank 2, it is diverted to each diversion pipe 3 and discharged into a sewage treatment plant through the diversion pipes 3. The diversion of sewage by multiple diversion pipes 3 makes the sewage flow in each diversion pipe 3 less.

[0022] A conical guide surface 21 is provided at the bottom of the transfer tank 2, and the sewage is evenly diverted to each diversion pipe 3 through the conical guide surface 21. The conical guide surface 21 is provided so that the dirt in the sewage is not easy to accumulate at the bottom of the transfer tank 2, thereby reducing the cleaning burden of the transfer tank 2. Among them, the bottom end of the conical guide surface 21 is smoothly connected to the bottom wall of the diversion pipe 3, so that the sewage can be discharged into the diversion pipe 3 more smoothly.

[0023] The shunt pipe 3 includes a lateral section 31, a vertical section 32 and a buffer section 33 which are connected in sequence. A sieve plate 4 is fixed obliquely on the side wall of the vertical section 32. The sieve plate 4 is provided with a plurality of first water filtering holes 41. It should be noted that the opening area of ​​the first water filtering holes 41 on the sieve plate 4 accounts for at least 75% of the total area of ​​the sieve plate 4. A through hole 321 is also provided on the side wall of the vertical section 32, which is connected to the bottom of the sieve plate 4. A sewage inclined pipe 5 is also fixed on the side wall of the vertical section 32, which is connected to the through hole 321. After the sewage passes through the lateral section 31, it falls from the vertical section 32 and flows through the sieve plate 4 to the vertical section 32 below the sieve plate 4. The solid pollutants in the sewage are retained on the sieve plate 4, and slide along the sieve plate 4 into the sewage inclined pipe 5, and are discharged from the shunt pipe 3 along the sewage inclined pipe 5, thereby realizing the preliminary filtration treatment of the sewage.

[0024] It should be noted that the transverse section 31, the vertical section 32 and the buffer section 33 are all pipes with square cross-sections, and the bottom walls of the sieve plate 4 and the sewage inclined pipe 5 are coplanar, so that the solid pollutants can slide smoothly along the sieve plate 4 to the sewage inclined pipe 5 and be discharged from the sewage inclined pipe 5. In the actual production process, the shunt pipe 3 is a joint pipe with a small volume and length. The shunt pipe 3 can specifically be a PVC pipe, which is produced and formed in a production workshop and then transported to the site for installation. The shunt pipe 3 of this application is used as a connecting joint to connect the rest of the drainage pipes. In addition, the drawings of this application are only for illustration, used to show the structure of each component, and the proportional relationship between the components is not drawn according to the actual size.

[0025] A plurality of second water filtering holes 51 are also provided in a part of the bottom wall of the sewage discharge inclined pipe 5, and a recovery pipe 6 is also connected between the sewage discharge inclined pipe 5 and the vertical section 32, one end of the recovery pipe 6 is connected with all the second water filtering holes 51, and the other end is connected with the side wall of the part of the vertical section 32 located below the sieve plate 4. By providing the second water filtering holes 51 in the bottom wall of the sewage discharge inclined pipe 5, the leakage path of the sewage can be extended, so that the sewage is collected and discharged into the vertical section 32 as much as possible, and the amount of sewage discharged outside the diversion pipe 3 along the sewage discharge inclined pipe 5 is reduced.

[0026] In addition, a guide plate 7 is rotatably mounted on the side wall of the vertical section 32. One end of the guide plate 7 is rotatably connected to the side wall of the vertical section 32 where the through hole 321 is provided, and the other end is inclined toward the opposite side wall of the vertical section 32, and the end of the guide plate 7 is spaced from the side wall of the vertical section 32 and the sieve plate 4. The guide plate 7 guides the flow of sewage, so that the sewage falls to the end of the sieve plate 4 away from the through hole 321 as much as possible, thereby extending the path of the sewage flowing along the sieve plate 4, so that the sewage can be discharged into the vertical section 32 through the first water filter hole 41 as much as possible. A first elastic member 71 is also provided between the guide plate 7 and the side wall of the vertical section 32. The first elastic member 71 can be compressed so that the guide plate 7 can rotate toward the side wall of the vertical section 32 where the through hole 321 is provided. When there are solid pollutants that are difficult to pass through the gap between the end of the guide plate 7 and the side wall of the vertical section 32, the guide plate 7 can be driven to rotate under the thrust of the solid pollutants and the pressure of the sewage, so that the solid pollutants can be discharged smoothly. The first elastic member 71 can specifically be a spring structure, or a plastic rubber structure or other elastic material.

[0027] The side wall of the vertical section 32 located above the through hole 321 is also rotatably mounted with a splash plate 8, which partially blocks the through hole 321. Since the gravitational acceleration is large when the sewage vertically falls from the end of the vertical section 32 to the sieve plate 4, when the sewage falls onto the sieve plate 4, the sewage splashes, and the splash plate 8 can buffer the impact of the splashed sewage, and rebound the sewage onto the sieve plate 4, and then fall into the diversion pipe 3 through the sieve plate 4. A second elastic member is also provided between the splash plate 8 and the side wall of the vertical section 32, and the second elastic member realizes the rotatable connection between the splash plate 8 and the side wall of the vertical section 32, and the splash plate 8 can rotate toward the inside of the vertical section 32, wherein the second elastic member can specifically be a torsion spring.

[0028] The filtering structure of the present application is only used to filter solid pollutants whose volume in sewage is larger than the aperture of the first filter hole. After filtering, the solid pollutants can be automatically discharged along the sewage inclined pipe 5, without manual daily maintenance and cleaning, which is more convenient; in addition, the sewage flushes the screen plate 4, the splash plate 8, the guide plate 7 and the partial section of the sewage inclined pipe 5 for a long time, so that the screen plate 4, the splash plate 8, the guide plate 7 and the sewage inclined pipe 5 are not easy to accumulate pollutants, reducing the cleaning cost of the staff; when the diverter pipe 3 of the present application discharges sewage for a long time, so that pollutants accumulate on the bottom wall of the screen plate 4 and the sewage inclined pipe 5, the staff can extend the scraper structure from the outlet end of the sewage inclined pipe 5, and use the scraper structure to scrape the pollutants on the bottom wall of the screen plate 4 and the sewage inclined pipe 5, so that the cleaning and maintenance are simple, convenient and fast. Because the splash plate 8 is rotatably connected to the side wall of the vertical section 32, the scraper structure can also extend into the side wall of the vertical section 32 corresponding to the height of the splash plate 8, thereby expanding the cleaning range.

[0029] It should be noted that the present application can adaptively design the number of diversion pipes 3 connected to the two sides of the transfer tank according to the municipal sewage discharge volume, so as to ensure that the sewage flow in each diversion pipe 3 is the amount that the water filtration structure can bear. For special events, such as floods and other accidents, the outlet end of the sewage inclined pipe 5 can be blocked, and the bottom wall of the sewage inclined pipe 5 in the area where the second water filter hole 51 is opened can be smashed, and the filtering function of the diversion pipe 3 can be disabled, so that the sewage in the diversion pipe 3 can quickly pass through the vertical section 32 and the recovery pipe 6 and then be discharged into the buffer section 33. The outlet end of the buffer section 33 is connected to the sewage treatment plant.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
