Description

Technical Field

[0001] This utility model relates to the field of sewage pipeline technology, and in particular to sewage inverted siphon pipeline. Background Technology

[0002] In modern urban sewage discharge systems, inverted siphon pipes play a crucial role. With the increasing demand for drainage, inverted siphon pipes have emerged to meet this need. They can cleverly cross rivers, valleys, and roads to ensure the continuous and stable transport of sewage. With their unique siphon principle, they use the liquid level difference to drive the flow of sewage without the need for additional power equipment, which greatly saves energy and operating costs. They are widely used in municipal sewage treatment, industrial wastewater discharge, and other fields, providing solid support for the efficient operation of urban infrastructure and the protection of the ecological environment.

[0003] A search revealed a Chinese patent announcement number, CN217232196U, which discloses a municipal construction obstacle-crossing inverted siphon pipe device, belonging to the field of municipal engineering technology. It includes a first sewage well and a second sewage well fixedly connected to the construction ground. The first sewage well and the second sewage well are located at different levels. The top of the first sewage well can be detachably installed with a cover plate. A connecting pipe is fixedly inserted into the bottom wall of the inner cavity of the first sewage well. A drainage pipe is fixedly inserted into the bottom wall of the inner cavity of the second sewage well. This municipal construction obstacle-crossing inverted siphon pipe device, through the coordinated use of the construction ground, the first sewage well, the second sewage well, the cover plate, the connecting pipe, the drainage pipe, and the flow pipe, allows water from the first sewage well to pass through the construction obstacle and enter the second sewage well. Furthermore, the coordinated use of a servo motor and agitator blades minimizes siltation within the flow pipe, thus effectively avoiding obstacles during pipe construction. However, in actual use, due to the large amount of impurities and sand in the sewage, once they enter the pipe, they can cause blockages. Although the agitator blades stir the pipe, the impurities in the sewage can impact the blades, causing damage and making it difficult to remove silt from the pipe, resulting in continued blockages. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sewage inverted siphon pipe, which aims to improve the problem of pipe blockage caused by a large number of impurities and sand particles in sewage in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sewage inverted siphon pipe, comprising two water well cylinders, with a connecting pipe connecting the outer sides of the water well cylinders, and a bent pipe connecting adjacent sides of the outer walls of the two water well cylinders, with flanges fixedly connected to adjacent sides of the two bent pipes, and horizontal pipes fixedly connected to adjacent sides of the two flanges, with a grid plate provided at the top of the inner wall of the water well cylinder, the outer wall of the grid plate engaging with the top of the inner wall of the water well cylinder, a conical collecting cylinder fixedly connected to the middle of the inner wall of the water well cylinder, multiple drain outlets provided on the outer wall of the conical collecting cylinder, a sedimentation collecting cylinder fixedly connected to the bottom end of the conical collecting cylinder, a conical baffle fixedly connected to the middle of the inner wall of the conical collecting cylinder, multiple inclined guide blocks fixedly connected to the top of the inner wall of the conical collecting cylinder, and limit blocks fixedly connected to the outer sides of the multiple inclined guide blocks, and a cleaning and pushing mechanism provided on the inner wall of the horizontal pipe.

[0006] The above technical solution involves a connecting pipe serving as the main conduit for sewage flow. Sewage enters from the top of the well cylinder, passes through a grid plate to intercept large particles, and then flows into a conical collection cylinder. Under the action of the inclined guide block, the sewage generates a swirling flow, guiding impurity particles to the bottom of the conical collection cylinder. A conical baffle prevents direct discharge. After the water level rises to the drain outlet, the sewage enters the bottom of the well cylinder and crosses the obstacles through a siphon structure formed by the bent pipe and horizontal pipe, completing the discharge and preventing impurities from entering the sewage discharge pipe.

[0007] As a further description of the above technical solution:

[0008] The cleaning and pushing mechanism includes a rotating ring. The outer wall of the rotating ring is slidably connected to the left side of the inner wall of the horizontal pipe. Multiple inclined bars are fixedly connected to the inner wall of the rotating ring. A cylinder is fixedly connected to the outer wall of each of the multiple inclined bars. A spiral push plate is fixedly connected to the right side of the rotating ring. Multiple reinforcing columns are fixedly connected to the outer wall of the cylinder. The other end of each of the multiple reinforcing columns is fixedly connected to the inner wall of the spiral push plate. An inclined push bar is fixedly connected to the outer wall of each reinforcing column.

[0009] Through the above technical solution: when sewage flows in the siphon pipe formed by the bend pipe and the horizontal pipe, small impurities will collide and settle at the bottom of the horizontal pipe. The sewage flow drives the inclined bar, rotating ring, cylinder and spiral pusher to rotate, pushing the impurities to the other side. The reinforcing column enhances the structural strength, and the inclined pusher accelerates the movement of impurities and prevents them from settling again, thereby avoiding the risk of the horizontal pipe being blocked by small impurities.

[0010] As a further description of the above technical solution:

[0011] A suction pump is fixedly connected to the bottom of the inner wall of the limiting block. One end of the suction pump is connected to a suction pipe. The bottom end of the outer wall of the suction pipe passes through the bottom end of the limiting block. The other end of the suction pump is connected to a discharge pipe. The other end of the discharge pipe passes through the outer wall of the limiting block and the well cylinder.

[0012] The above technical solution utilizes the suction pump to generate strong negative pressure, collecting the settled sludge. The sludge can be sucked out of the sedimentation collection cylinder through the suction pipe, and discharged to a designated location through the discharge pipe, thus maintaining the smooth operation of the entire sewage inverted siphon pipeline system.

[0013] As a further description of the above technical solution:

[0014] The top center of the limiting block is provided with a collection groove, and the top of the limiting block is provided with multiple guide grooves around it. One side of each of the multiple guide grooves is connected to the collection groove.

[0015] The above technical solution provides a collection groove for the wastewater that has undergone preliminary filtration by the grid disc to gather in a concentrated manner. The guide trough can then guide the collected wastewater into the conical collection cylinder, thereby accelerating the discharge of wastewater.

[0016] As a further description of the above technical solution:

[0017] A pressure sensor is fixedly connected to the outer wall of the sedimentation collection cylinder, and the pressure sensor is waterproofed.

[0018] The above technical solution enables real-time monitoring of the pressure inside the sedimentation collection cylinder using a pressure sensor, facilitating timely removal of accumulated impurities. Waterproofing the pressure sensor prevents water from entering and damaging it due to moisture, ensuring its long-term, stable, and accurate operation.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the grid plate has a connecting hole, and the inner wall of the well cylinder is rounded.

[0021] The above technical solution ensures that sewage can pass smoothly through the grid plate through the connecting holes, allowing the sewage to flow normally inside the well cylinder. The smooth treatment of the inner wall of the well cylinder can significantly reduce the resistance of sewage when flowing inside the well cylinder.

[0022] As a further description of the above technical solution:

[0023] The outer wall size of the rotating ring is the same as the inner wall size of the horizontal tube, and both ends of the horizontal tube are sealed.

[0024] The above technical solution ensures that the outer wall size of the rotating ring matches the inner wall size of the horizontal pipe, allowing the rotating ring to slide or rotate tightly against the inner wall of the horizontal pipe. Sealing both ends of the horizontal pipe prevents sewage leakage and ensures a stable flow environment for sewage within the horizontal pipe.

[0025] As a further description of the above technical solution:

[0026] The inner wall of the bend in the bent tube is treated with wear resistance, and a filter cover is fixedly connected to the bottom of the outer wall of the tube.

[0027] The above technical solution involves applying a wear-resistant treatment to the inner wall of the bend in the pipe, which enhances the wear resistance of the inner wall and extends the service life of the bend. The filter cover can intercept larger debris in the sewage, preventing these debris from entering the suction pipe and thus avoiding blockage of the suction pipe and pump.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, sewage enters from the top of the well cylinder, and after being intercepted by the grid plate for large particles, it flows into the conical collection cylinder. Under the action of the inclined guide block, the sewage generates a swirling flow, and the impurity particles are guided to the bottom of the conical collection cylinder. The conical baffle prevents the sewage from being discharged directly. After the water level rises to the drain outlet, the sewage enters the bottom of the well cylinder. Through the siphon structure's bent pipe and horizontal pipe, the sewage can cross the obstacles to complete the discharge, avoiding impurities from entering the discharge pipe.

[0030] 2. In this utility model, when sewage flows in the pipe, fine impurities will settle at the bottom of the horizontal pipe, and the sewage flow will drive the inclined bar, rotating ring, cylinder and spiral push plate to rotate, pushing the impurities to one side to prevent blockage. The reinforcing column enhances the structural strength, and the inclined push bar accelerates the movement of impurities, thereby reducing the risk of sewage pipe blockage.

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a sewage inverted siphon pipe, comprising two well cylinders 1. The well cylinders 1 are connected to a connecting pipe 3 on their outer sides. Sewage enters the entire sewage pipe through the top of the well cylinders 1. The connecting pipe 3 is the main flow channel for the sewage. Adjacent sides of the outer walls of the two well cylinders 1 are connected to bent pipes 4. Adjacent sides of the two bent pipes 4 are fixedly connected to flanges 5. Adjacent sides of the two flanges 5 are fixedly connected to horizontal pipes 6. The bent pipes 4 and horizontal pipes 6 form a siphon structure, allowing sewage to overcome obstacles. A grid plate 7 is installed at the top of the inner wall of the well cylinder 1. Sewage containing large particles will be intercepted by the grid plate 7, preventing them from entering the well cylinder 1. The outer wall of the grid plate 7 engages with the top of the inner wall of the well cylinder 1. A conical collection cylinder 8 is fixedly connected to the middle of the inner wall of the well cylinder 1. The outer wall of the collection cylinder 8 is provided with multiple drain outlets 9. The bottom end of the conical collection cylinder 8 is fixedly connected to a sedimentation collection cylinder 10. The sewage after initial interception will fall above the limiting block 13 and flow into the conical collection cylinder 8. Under the guidance of the inclined guide block 12, the sewage will generate a swirling flow in the conical collection cylinder 8, so that the particles in the impurities are guided to the bottom by the conical characteristics of the conical collection cylinder 8. A conical baffle 11 is fixedly connected to the middle of the inner wall of the conical collection cylinder 8. The conical baffle 11 can prevent the sewage from flowing in from being discharged directly from the drain outlet 9. As the water level rises, it will flood the drain outlet 9 and enter the bottom of the water well cylinder 1. Multiple inclined guide blocks 12 are fixedly connected to the top of the inner wall of the conical collection cylinder 8. Limit blocks 13 are fixedly connected to the outer side of each of the multiple inclined guide blocks 12. A cleaning and pushing mechanism 2 is provided on the inner wall of the horizontal pipe 6.

[0040] Specifically, the connecting pipe 3 is the pipeline for the entire sewage flow. External sewage enters the entire sewage pipeline through the top of the well cylinder 1. The external sewage contains large particles of debris, which are intercepted by the grid plate 7, preventing them from entering the well cylinder 1. After the initial interception by the grid plate 7, the sewage falls above the limiting block 13 and flows into the conical collection cylinder 8. Under the guidance of the inclined guide block 12, the sewage swirls in the conical collection cylinder 8, causing the particles of impurities to be guided to the bottom by the conical characteristics of the conical collection cylinder 8. The conical baffle 11 prevents the sewage from being discharged directly from the drain outlet 9. As the water level rises, it floods the drain outlet 9, thus entering the bottom of the well cylinder 1 and the entire sewage drainage system. Then, through the bend pipe 4 and the horizontal pipe 6, a siphon structure is formed, allowing the sewage to cross the obstacles and complete the discharge, thereby preventing a large number of impurities from entering the sewage discharge pipeline.

[0041] Reference Figure 5The cleaning and pushing mechanism 2 includes a rotating ring 201. The outer wall of the rotating ring 201 is slidably connected to the left side of the inner wall of the horizontal pipe 6. Multiple inclined bars 202 are fixedly connected to the inner wall of the rotating ring 201, and cylinders 203 are fixedly connected to the outer walls of each inclined bar 202. A spiral pusher plate 204 is fixedly connected to the right side of the rotating ring 201. The flow of sewage will cause the inclined bars 202 to rotate, which in turn will cause the rotating ring 201 and cylinders 203 to rotate, and simultaneously cause the spiral pusher plate 204 to rotate, thus causing the sediment to... Impurities deposited in the horizontal pipe 6 are moved to the other side by the push of the spiral pusher plate 204. Multiple reinforcing columns 205 are fixedly connected to the outer wall of the cylinder 203. The reinforcing columns 205 can increase the structural strength between the cylinder 203 and the spiral pusher plate 204. The other end of the multiple reinforcing columns 205 is fixedly connected to the inner wall of the spiral pusher plate 204. Inclined pusher strips 206 are fixedly connected to the outer wall of the reinforcing columns 205. The inclined pusher strips 206 can accelerate the movement of fine impurities in the sewage and prevent them from settling in the horizontal pipe 6.

[0042] Specifically, when sewage flows in the pipe, due to the collisions caused by the flow of sewage in the siphon pipe formed by the bend pipe 4 and the horizontal pipe 6, a large number of fine impurities will gradually settle at the bottom of the horizontal pipe 6. At this time, the flow of sewage will drive the inclined bar 202 to rotate, which in turn drives the rotating ring 201 and the cylinder 203 to rotate, and at the same time drives the spiral push plate 204 to rotate. This causes the impurities settled in the horizontal pipe 6 to move to the other side under the push of the spiral push plate 204. Furthermore, the reinforcing column 205 can increase the structural strength between the cylinder 203 and the spiral push plate 204. At the same time, under the action of the inclined push bar 206, the fine impurities in the sewage can move faster, preventing them from settling in the horizontal pipe 6, thereby avoiding the risk of the horizontal pipe 6 being blocked due to the accumulation of a large number of fine impurities.

[0043] Reference Figure 3 and Figure 4 A suction pump 14 is fixedly connected to the bottom of the inner wall of the limiting block 13. The suction pump 14 can generate a strong negative pressure by its own suction capacity to collect the settled sludge. One end of the suction pump 14 is connected to a suction pipe 15, which can suck out the sludge settled in the sedimentation collection cylinder 10. The bottom end of the outer wall of the suction pipe 15 penetrates the bottom end of the limiting block 13. The other end of the suction pump 14 is connected to a discharge pipe 16, and the other end of the discharge pipe 16 penetrates the outer wall of the limiting block 13 and the well cylinder 1. The discharge pipe 16 can discharge the pumped sludge to a designated location. A collection groove 17 is opened in the middle of the top of the limiting block 13. The collection groove 17 can provide a space for the sewage that has been pre-filtered by the grid plate 7 to gather. Multiple guide grooves 18 are opened around the top of the limiting block 13. One side of each guide groove 18 is connected to the collection groove 17. The guide grooves 18 can guide the collected sewage to the conical collection cylinder 8, thereby accelerating the discharge of sewage.

[0044] Specifically, the suction pump 14 can generate strong negative pressure by its own suction capacity to collect the settled sludge. The suction pipe 15 can suck out the sludge settled in the sedimentation collection cylinder 10, and the discharge pipe 16 can discharge the extracted sludge to a designated location, thereby maintaining the smooth operation of the entire sewage inverted siphon pipeline system. The collection groove 17 provides a space for the sewage that has undergone preliminary filtration by the grid disc 7 to gather. The guide groove 18 can guide the collected sewage to the conical collection cylinder 8, thereby accelerating the discharge of sewage.

[0045] Reference Figure 2 , Figure 3 and Figure 5 A pressure sensor 19 is fixedly connected to the outer wall of the sedimentation collection cylinder 10. The pressure sensor 19 can monitor the pressure inside the sedimentation collection cylinder 10 in real time and accurately. The pressure sensor 19 is waterproof to prevent water from entering the sensor. A connecting hole 20 is opened on the outer wall of the grid plate 7 to ensure that sewage can pass through the grid plate 7 smoothly. The inner wall of the well cylinder 1 is rounded to significantly reduce the resistance of sewage when flowing in the well cylinder 1. The outer wall size of the rotating ring 201 is the same as the inner wall size of the horizontal pipe 6, which can ensure that the rotating ring 201 can slide or rotate tightly against the inner wall of the horizontal pipe 6. The two ends of the horizontal pipe 6 are sealed to prevent sewage leakage and ensure that the sewage forms a stable flow environment in the horizontal pipe 6. The inner wall of the bend of the bent pipe 4 is treated with wear resistance to enhance the wear resistance of the inner wall and extend the service life of the bent pipe 4. A filter cover 21 is fixedly connected to the bottom of the outer wall of the suction pipe 15 to intercept larger debris in the sewage.

[0046] Specifically, the pressure sensor 19 can monitor the pressure inside the sedimentation collection cylinder 10 in real time, facilitating timely removal of accumulated impurities. The pressure sensor 19 is waterproofed to prevent water from entering and damaging it due to moisture, ensuring its long-term, stable, and accurate operation. The connecting hole 20 allows sewage to pass smoothly through the grid plate 7, enabling normal flow within the well cylinder 1. The rounded inner wall of the well cylinder 1 significantly reduces resistance to sewage flow. The rotating ring 201... The outer wall size is the same as the inner wall size of the horizontal pipe 6, which ensures that the rotating ring 201 can slide or rotate tightly against the inner wall of the horizontal pipe 6. The two ends of the horizontal pipe 6 are sealed to prevent sewage leakage and ensure that the sewage forms a stable flow environment in the horizontal pipe 6. The inner wall of the bend of the bent pipe 4 is treated with wear resistance to enhance the wear resistance of the inner wall and extend the service life of the bent pipe 4. The filter cover 21 can intercept larger debris in the sewage and prevent these debris from entering the suction pipe 15, thereby avoiding blockage of the suction pipe 15 and the suction pump 14.

[0047] Working principle: First, the connecting pipe 3 serves as the main channel for the entire sewage flow system. External sewage enters the system through the top of the well cylinder 1. Since the external sewage may contain large particles, these particles are intercepted by the grid disc 7 to prevent them from entering the well cylinder 1. The sewage, after initial filtration by the grid disc 7, falls above the limiting block 13 and flows into the conical collection cylinder 8. Under the action of the inclined guide block 12, the sewage swirls within the conical collection cylinder 8. Utilizing the characteristics of the conical structure, impurities are guided to the bottom. The conical baffle 11 ensures that the sewage is not directly discharged from the drain outlet 9. As the water level gradually rises until it reaches the drain outlet 9, the sewage enters the bottom of the well cylinder 1 and eventually flows into the entire sewage drainage pipeline system. Subsequently, the sewage overcomes obstacles through the siphon structure formed by the bent pipe 4 and the horizontal pipe 6. The discharge process is completed, thus preventing a large number of impurities from entering the sewage discharge pipe. Through the cleaning and pushing mechanism 2, the sewage flowing in the pipe, when it flows through the siphon pipe composed of the bend pipe 4 and the horizontal pipe 6, will gradually deposit a large number of fine impurities at the bottom of the horizontal pipe 6 due to the collision. At this time, the flow of sewage will drive the inclined bar 202 to rotate, which will cause the rotating ring 201 and the cylinder 203 to rotate. At the same time, the spiral push plate 204 will also rotate, pushing the impurities deposited in the horizontal pipe 6 to the other side. By reinforcing the column 205, the structural stability between the cylinder 203 and the spiral push plate 204 can be enhanced. In addition, under the action of the inclined push bar 206, the fine impurities in the sewage can be accelerated to prevent them from depositing in the horizontal pipe 6, thereby avoiding the risk of pipe blockage caused by the accumulation of a large number of fine impurities.
