Description

Technical Field

[0001] The present invention relates to the technical field of domestic sewage pipe networks, and in particular to a sewage pipe network sedimentation control system and method based on flow velocity segmentation enhancement. Background Art

[0002] At present, the low efficiency of centralized collection of urban domestic sewage and the low concentration of influent in sewage treatment plants are still common. As the main place for collecting and transporting domestic sewage, the sewage pipe network is an important guarantee for low-carbon and efficient sewage treatment.

[0003] Pollutants deposited in domestic sewage pipes mainly come from organic pollutants, inorganic particles, microbial metabolites, etc. in domestic sewage. These substances gradually accumulate in the pipes and form sediments, posing a serious threat to the pipeline's transportation capacity, the subsequent sewage treatment plant's treatment efficiency and the water environment. At present, due to design defects or imperfect construction and operation management, pollutant deposition due to low flow rate will occur during the sewage transfer process. On the one hand, it is easy to block the pipe for a long time and affect normal use; on the other hand, low flow rate will also cause pollutants, especially organic matter, to deposit and decay, causing sewage treatment facilities to rely on adding external carbon sources to solve the imbalance of carbon, nitrogen and phosphorus ratios in the inlet water.

[0004] Therefore, it is necessary to provide a sedimentation control system and method based on increasing the flow rate of the pipeline network in combination with the actual construction and operation of the existing pipeline facilities, so as to reduce the pollutant deposition problem in the main silted sections of the community and municipal sewage pipeline network.

The sewage well is remodeled by deepening the bottom of the sewage well by 20 to 50 cm and making it into a conical structure, and the deepened part is treated for anti-seepage. A 10 to 30 cm high intercepting weir is set at the sewage well outlet of the sewage well, and the cutting type lifting pump is placed at the bottom of the sewage well, and the internal circulation pipeline is placed in the sewage well.

In response to the liquid level dropping to the stopping liquid level value, the sewage network sedimentation control system stops operating.

[0015] The above technical solution of the present invention has the following advantages compared with the prior art: (1) The present invention utilizes a pipe network sedimentation reduction control system including a cutting-type lifting pump, a filtering unit, an external flushing pipe, and an internal circulation pipe, so that long-term accumulated sediments are separated from the bottom of the pipe network and collected and transferred to the sewage treatment facility in a timely manner. This can effectively prevent sewage from being deposited in sewage wells and pipes, greatly reduce the deposition and attenuation of organic pollutants during the collection and transfer process, and improve the centralized collection efficiency of sewage pollutants.

[0016] (2) The internal circulation system of the present invention can be combined with timed automatic control technology to achieve remote monitoring and timed start-up, which is convenient for real-time management of the operating status of community pipe networks and municipal pipe networks, and can effectively reduce the accumulation of sediments and the frequency of pipe blockages, reduce the frequency of pipe network maintenance, and provide a new solution for existing drainage systems.

[0017] (3) The present invention is highly targeted, practical and operable, and is of great significance for supporting the improvement of existing sewage quality and efficiency, improving water environment quality, and low-carbon operation and maintenance of pipeline networks.

[0018] Through the above technical scheme of the present invention, in order to solve the problem of pollutant deposition and low collection efficiency caused by too low flow rate in the whole process of domestic sewage collection and transfer from the source to the terminal, the present invention realizes the function of hydraulic circulation flushing by means of segmented increase of the flow rate of the pipe network through the coordinated use of a cutting-type lifting pump, an input pipe, an internal circulation pipe, an external flushing pipe and a booster nozzle, so that part of the sewage in the sewage well at the end of the silted pipe section is diverted to the sewage well at the starting end, thereby forming a circulating flushing flow state in the pipe to solve the problem of pollutant deposition and low collection efficiency caused by too low flow rate in the whole process of domestic sewage collection and transfer from the source to the terminal. Furthermore, the present invention is further provided with a filtering unit. Through the setting of the filtering unit, it can be used in the diversion When sewage is transported, solid impurities in the sewage are prevented from entering the cutting type lifting pump and causing blockage, thereby ensuring the normal operation of the system. In order to solve the problem that a large amount of dirt may be attached to the inner wall of the domestic sewage pipe with a long service life and a long transportation distance, it is difficult to handle the problem, by setting an auxiliary cleaning unit. Through the setting of the auxiliary cleaning unit, the detergent can be automatically and quantitatively added to the circulating water during hydraulic circulation flushing. Therefore, the detergent and hydraulic circulation flushing can fully and effectively deal with and remove the dirt in the domestic sewage pipe with a long service life and a long transportation distance. At the same time, the detergent does not require manpower and extra power source when adding, it is easy to use, and the amount of addition is adjustable. It is particularly suitable for use in sewage pipe networks with a long service life and a long transportation distance. BRIEF DESCRIPTION OF THE DRAWINGS

Those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0036] Reference Figure 1 , Fig.11 As shown, a sewage pipe network sedimentation control system based on flow rate segmentation enhancement includes: The cutting type lifting pump 1 is arranged in the sewage well 9, and is used to extract the sewage in the sewage well 9, and simultaneously cut the solid impurities and fibers in the sewage; A filter unit 3 is provided at the input end of the cutting type lift pump 1, and is used to prevent the cutting type lift pump 1 from being blocked when pumping sewage, and can automatically rotate during filtering; An internal circulation pipe 2, one end of which is connected to the output end of the cutting type lifting pump 1, and the other end of the internal circulation pipe 2 extends to the sewage well 9, so as to spray the sewage pumped by the cutting type lifting pump 1 to the bottom of the sewage well 9 for flushing, so that the sediment is separated from the bottom of the sewage well and is in a suspended state; An external flushing pipe 4, one end of which is connected to the output end of the cutting type lifting pump 1, and the other end of which extends to the sewage well 10 at the starting end of the silted pipe section, and is used to transport the sewage in the sewage well 9 to the sewage well 10 at the starting end; A water wheel rotating unit 5 is arranged on the external flushing pipe 4 and has a pressure boosting nozzle 6 at one end, and the pressure boosting nozzle 6 is used to pressurize and spray out the sewage; An auxiliary cleaning unit 8, the bottom end of which is connected to the inner cavity of the external flushing pipe 4, and is used to automatically add cleaning agent when conveying sewage; The regulating linkage unit 7 is disposed between the auxiliary cleaning unit 8 and the water wheel rotating unit 5 , and is used to transmit the rotational motion of the water wheel rotating unit 5 to the auxiliary cleaning unit 8 , so as to control the amount of detergent added to the auxiliary cleaning unit 8 .

[0037] Through the above technical solution, by using the cutting type lifting pump 1, the internal circulation pipe 2, the external flushing pipe 4 and the boosting nozzle 6 in coordination, the flow rate of the pipe network is increased in sections, and the function of hydraulic circulation flushing is realized, and part of the sewage in the sewage well at the end of the silted pipe section is diverted to the sewage well at the starting end, thereby forming a circulating flushing flow state in the pipeline, so as to solve the problem of pollutant deposition and low collection efficiency caused by too low flow rate in the whole process of domestic sewage collection and transfer from the source to the end. Furthermore, through the setting of the filtering unit 3, when diverting sewage, it is possible to avoid the solid impurities in the sewage from entering the interior of the cutting type lifting pump 1 to cause blockage, thereby ensuring the normal operation of the system, in order to solve the problem that a large amount of dirt may be attached to the inner wall of the domestic sewage pipe with a long service life and a long transportation distance, which is difficult to handle. By further arranging an auxiliary cleaning unit 8, a quantitative amount of detergent can be automatically added to the circulating water during hydraulic circulation flushing. Thus, the detergent combined with hydraulic circulation flushing can fully and effectively handle and remove the dirt in the domestic sewage pipes that are old and have a long transportation distance. At the same time, no manpower and extra power source are required when adding the detergent. It is easy to use and the amount of addition is adjustable. It is particularly suitable for use in sewage pipe networks that are old and have a long transportation distance.

[0038] It should be noted that the sewage extracted by the cutting type lifting pump 1 is sprayed to the bottom of the sewage well 9 through the internal circulation pipe 2 for flushing, which can effectively disturb the pollutants such as sediment and solid particles at the bottom of the sewage well 9, so that the pollutants are separated from the bottom of the sewage well and are in a suspended state, forming a circulating water flow, and avoiding the attachment and accumulation of pollutants at the bottom of the well. By repeatedly flushing the bottom of the well, the retention of large particles or larger solid debris at the inlet of the cutting type lifting pump 1 can be reduced, and the filter unit 3 can be prevented from being adhered to or entangled by impurities, thereby improving the continuous operation capability of the system.

[0039] Specifically, the internal circulation pipeline 2 is provided with a regulating valve 11 for adjusting the water distribution between the internal circulation pipeline 2 and the external flushing pipeline 4; the external flushing pipeline 4 is provided with a check valve 17. Also provided are: A control unit 14, the control unit 14 comprises a timed start module 15 electrically connected to the cutting type lift pump 1, the timed start module 15 is used to control the start time of the cutting type lift pump 1; The liquid level meter 16 is arranged in the sewage well 9 and is electrically connected to the control unit 14. The liquid level meter 16 is used to obtain the liquid level data in the sewage well 9 in real time. The control unit 14 can control the automatic start and stop of the cutting type lifting pump 1 according to the liquid level data.

[0040] For further technical solutions, please refer to Figure 2 As shown, the input end of the cutting type lifting pump 1 is provided with an input pipe 13, and the filtering unit 3 includes a suction nozzle 301, a rotating sleeve 302, a filtering hole 303, a fixed round rod 304 and a spiral blade 305. The suction nozzle 301 is fixedly arranged at one end of the input pipe 2, and the rotating sleeve 302 is rotatably sleeved at the arc-shaped wall of the suction nozzle 301. A plurality of filtering holes 303 are opened on the rotating sleeve 302. A fixed round rod 304 is fixedly connected at the center position of the inner wall of the rotating sleeve 302, and a plurality of spiral blades 305 are fixedly connected at the arc-shaped wall of the fixed round rod 304. By setting the filter hole 303, the solid impurities in the sewage can be filtered out, and the blockage caused by the solid impurities entering the interior of the cutting type lifting pump 1 when the sewage is pumped can be avoided. At the same time, due to the setting of the spiral blade 305, when the water flows into the inner cavity of the rotating sleeve 302, the spiral blade 305 can be driven to rotate due to the action of the water flow, so that the fixed round rod 304 can be driven to rotate through the rotation of the spiral blade 305, and then the rotating sleeve 302 can be driven to rotate, so that the rotation of the rotating sleeve 302 can realize the self-rotation function during the water pumping process, and the dirt attached to the filter hole 303 can be thrown off through the rotation, so as to avoid the problem of dirt attached to the filter hole 303 causing blockage. Therefore, compared with ordinary filtering equipment, the filter unit 3 is particularly suitable for use in domestic sewage pipes.

[0041] For details, please refer to Figure 3 As shown, the water wheel rotating unit 5 includes a fixed sleeve 501, a fixed bracket 502, a rotating rod 503 and a turbine 504. The fixed sleeve 501 is fixedly connected to one end of the external flushing pipe 4, and a booster nozzle 6 is fixedly connected to one end of the fixed sleeve 501. Through the above arrangement, the sewage in the sewage well 9 can be transported to the inside of the sewage well 10 at the starting end through the external flushing pipe 4 through the operation of the cutting type lifting pump 1, thereby realizing a circulating flushing flow state in the pipeline, thereby improving the problem of pollutant deposition caused by too low flow rate in the domestic sewage pipeline during the sewage transfer process. At the same time, through the arrangement of the booster nozzle 6, pressurized water spraying can be performed, making the spraying force stronger, which is conducive to flushing down the dirt attached to the inner wall of the domestic sewage pipeline, and improving the cleaning effect.

Through the above arrangement, when water flows through the fixed sleeve 501, the water flow can drive the turbine 504 to rotate, so that the rotation of the turbine 504 can drive the rotating rod 503 to rotate, and then the rotation of the rotating rod 503 can drive the bevel gear A505 to rotate, so that the rotation of the bevel gear A505 can drive the bevel gear B507 to rotate, and then drive the connecting rod 506 to rotate. It can be understood that when the water circulates, it can automatically drive the connecting rod 506 to rotate.

[0043] For further technical solutions, please refer to Figure 5As shown, the adjustment linkage unit 7 includes a support frame 701, a rotating rod 702, a gear set 706 and an adjustment part. The support frame 701 is fixedly arranged at the arc-shaped outer wall of the external flushing pipe 4. The upper surface of the support frame 701 is rotatably connected with the rotating rod 702. The arc-shaped wall of the rotating rod 702 is fixedly connected with the gear set 706. The gear set 706 is composed of a plurality of gears. A synchronous motion structure is arranged between the top end of the rotating rod 702 and the top end of the connecting rod 506. The synchronous motion structure is used to drive the synchronous movement between the connecting rod 506 and the rotating rod 702. Exemplarily, the synchronous motion structure includes a synchronous wheel A703, a synchronous belt 704 and a synchronous wheel B705, wherein the synchronous wheel A703 is fixedly arranged at the upper end of the rotating rod 702, and the synchronous wheel B705 is fixedly arranged at the upper end of the connecting rod 506, and a synchronous belt 704 is sleeved and connected between the synchronous wheel A703 and the synchronous wheel B705. Through the present technical solution, when the connecting rod 506 rotates, the synchronous wheel B705 can be driven to rotate, thereby driving the synchronous belt 704 to move, thereby driving the synchronous wheel A703 to rotate, and the rotation of the synchronous wheel A703 can drive the rotating rod 702 to rotate, thereby causing the gear set 706 to rotate.

[0044] For specific technical solutions, please refer to Figure 7 and Figure 8 As shown, the adjustment part includes a fixed plate frame 707, a rectangular fixed shell 708, a rectangular adjustment rod 709, a rotating connecting rod 710 and a linkage gear 711. The fixed plate frame 707 is fixedly arranged at the auxiliary cleaning unit 8. The fixed plate frame 707 is fixedly connected with a rectangular fixed shell 708. The inner cavity of the rectangular fixed shell 708 is slidably connected with a rectangular adjustment rod 709. The inner cavity of the rectangular adjustment rod 709 is provided with an inner cavity. The inner cavity of the rectangular adjustment rod 709 is fixedly connected with a fixed block 716. The rectangular fixed shell 708 An adjusting knob 718 is rotatably connected to the upper surface, one end of a threaded rod 717 is fixedly connected to the bottom end of the adjusting knob 718, the other end of the threaded rod 717 extends into the inner cavity of the rectangular adjusting rod 709, the threaded rod 717 passes through the fixed block 716 and is threadedly engaged with the fixed block 716, a rotating connecting rod 710 is rotatably connected to the bottom end of the rectangular adjusting rod 709, a linkage gear 711 is fixedly connected to the arc-shaped wall of the rotating connecting rod 710, and the linkage gear 711 is meshed with the gear set 706.

[0045] Through the above-mentioned arrangement, the threaded rod 717 can be driven to rotate by manually rotating the adjustment knob 718, so that the rotation of the threaded rod 717 can drive the fixed block 716 to move, thereby driving the rectangular adjustment rod 709 to move, and the movement of the rectangular adjustment rod 709 can drive the rotating connecting rod 710 to move, and then drive the linkage gear 711 to move, so that the position of the linkage gear 711 can be adjusted, and by adjusting the position of the linkage gear 711, it can mesh with different gears of the gear set 706, and by meshing with different gears, the function of adjusting the speed of the rotating linkage gear 711 can be realized. Specifically, when gear number 7061 is meshed with linkage gear 711, the rotation of gear number 7061 can drive linkage gear 711 to rotate, so that the rotation speed can be transmitted synchronously; when gear number 7062 is meshed with linkage gear 711, the reduction in the number of teeth will cause linkage gear 711 to pause intermittently, thereby reducing the rotation speed; when gear number 7063 is meshed with linkage gear 711, the rotation speed of linkage gear 711 is further reduced due to the smaller number of teeth. It can be seen from the above description that the function of adjusting the position of linkage gear 711 can be achieved by manually rotating the adjustment knob 718, so that by adjusting the position of linkage gear 711, it can be achieved to mesh with different gears of gear set 706, thereby achieving the function of adjusting the rotation speed of linkage gear 711.

[0046] Specifically, the rotating connecting rod 710 is provided with an inner cavity, and an inner rod 712 is slidably inserted in the inner cavity of the rotating connecting rod 710, the bottom end of the inner rod 712 extends to the outer surface of the external flushing pipe 4 and is rotatably connected to the external flushing pipe 4, and a bevel gear C713 is fixedly connected to the arc wall of the inner rod 712, and the bevel gear C713 and the bevel gear D715 are mutually meshed, and the bevel gear D715 is fixedly arranged at one end of the connecting rod 714, and the other end of the connecting rod 714 extends to the auxiliary cleaning unit 8 and is rotatably connected to the auxiliary cleaning unit 8. Through the above arrangement, the rotation of the linkage gear 711 can drive the rotating connecting rod 710 to rotate, thereby driving the inner rod 712 to rotate, and then driving the bevel gear C713 to rotate, thereby driving the bevel gear D715 to rotate, and then driving the connecting rod 714 to rotate.

[0047] For further technical solutions, please refer to Fig. 9 and Fig.10As shown, the auxiliary cleaning unit 8 includes a detergent storage bin 801, a rectangular tube 802, a rotating ball 803, a groove 804 and a rotating shaft 805. The inner cavity of the detergent storage bin 801 is filled with detergent, and one end of the rectangular tube 802 is fixedly connected to the bottom end of the inner cavity of the detergent storage bin 801. The other end of the rectangular tube 802 extends to the external flushing pipe 4 and is fixedly connected to the external flushing pipe 4. The inner cavity of the rectangular tube 802 is connected to the inner cavity of the external flushing pipe 4.

[0048] A spherical cavity is provided in the inner cavity of the rectangular tube 802, and a rotating shaft 805 is fixedly connected at the center position of the rotating ball 803. The rotating ball 803 is arranged in the spherical cavity of the rectangular tube 802 and rotates with the rectangular tube 802. A plurality of grooves 804 are provided on the arc wall of the rotating ball 803. One end of the rotating shaft 805 is fixedly connected to one end of the connecting rod 714. Through the technical solution, the rotation of the connecting rod 714 can drive the rotating shaft 805 to rotate, thereby driving the rotating ball 803 to rotate, and the detergent in the inner cavity of the detergent storage bin 801 will flow to the rotating ball due to the effect of gravity. At 803, part of the detergent enters the interior of the groove 804. When the groove 804 rotates to the bottom position, the detergent in the inner cavity of the groove 804 falls into the inner cavity of the external flushing pipe 4 by gravity, realizing the function of automatically adding detergent. The faster the rotating ball 803 rotates, the more detergent is added per unit time. By controlling the rotation speed of the rotating ball 803, the function of controlling the amount of detergent added is realized. Through the adjustment control of the adjustment part, the function of adjusting the rotation speed of the linkage gear 711 can be realized, and then the rotation speed of the rotating ball 803 can be controlled, thereby realizing the function of controlling the amount of detergent added. By adding detergent to the water flow during the hydraulic circulation flushing process, the dirt attached to the inner wall of the domestic sewage pipe can be cleaned more fully, the dirt can be removed, and the problem of pollutant deposition in the pipe can be significantly reduced. It is particularly suitable for sewage pipes with a long age and a long transportation distance.

[0049] Reference Figure 1 As shown, this embodiment also provides a method for using a sewage pipe network sedimentation control system based on flow rate segmentation enhancement, comprising the following steps: a. Conduct an on-site survey of the current status of the sewage pipe network, determine that the pipe section with an average flow rate lower than 0.1 m / s and a siltation depth exceeding 1 / 3 of the pipe diameter is the target pipe section 19, install the sewage well 9 at the end of the target pipe section 19 with the sewage pipe network sedimentation control system, and connect the starting end sewage well 10 connected to the starting end of the target pipe section 19 with the external flushing pipe 4; b. The sewage well 9 is remodeled by deepening the bottom of the sewage well 9 by 20 to 50 cm and making it into a conical structure, and the deepened part is treated for anti-seepage. A 10 to 30 cm high intercepting weir is set at the sewage well outlet 18 of the sewage well 9, and the cutting type lifting pump 1 is placed at the bottom of the sewage well 9, and the internal circulation pipe 2 is placed in the sewage well 9. The external flushing pipe 4 is shallowly buried from the sewage well 9 to the starting end sewage well 10; c. Sewage continuously enters the sewage well 9 through the water inlets 12 of other branch pipes and the target pipe section 19. When the starting conditions of the cutting type lifting pump 1 are met, the cutting type lifting pump 1 extracts a part of the sewage and sprays it to the bottom of the sewage well 9 for flushing, so that the sediment is separated from the bottom of the sewage well 9; at the same time, another part of the sewage extracted by the cutting type lifting pump 1 is transported to the starting end sewage well 10 through the external flushing pipe 4, and the sewage is pressurized and sprayed to the starting end sewage well 10 through the booster nozzle 6. By increasing the water volume and the flow rate of the high-pressure flushing lifting pipe section, the sediment is gradually separated from the pipe and enters the sewage well 9 at the end of the target pipe section 19 with the sewage; d. When the sedimentation control system is installed in the sewage pipe network in the residential area, set the timer start time period: 9:00~11:00, 13:00~17:00, and continuously operate the sedimentation control system of the sewage pipe network; e. When the sedimentation control system is installed in a municipal sewage network, a start liquid level value and a stop liquid level value are set for the cutting type lift pump 1. In response to the liquid level rising to the start liquid level value, the operation of the sewage network sedimentation control system is triggered. In response to the liquid level dropping to the stop liquid level value, the sewage network sedimentation control system stops operating.

[0050] The present invention solves the problem of pollutant deposition and low collection efficiency caused by too low flow rate in the whole process of domestic sewage collection and transfer from source to terminal by setting a sedimentation control system in the main silted pipe section to increase the flow rate of the pipe network in sections.

[0051] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
