Description

Technical Field

[0001] The invention relates to the technical field of sediment treatment, in particular to a comprehensive sediment treatment method for a water conservancy project. Background Art

[0002] At present, in the field of water conservancy projects, water sources often carry a large amount of sediment, which has many adverse effects on the normal operation of water conservancy projects, the effective use of water resources, and subsequent water supply, irrigation and other links.

[0003] Traditional sediment treatment methods have many deficiencies in the separation step. Traditional methods often rely on a single sedimentation process, which is not fine enough for sediment separation and makes it difficult to effectively remove fine sediment particles in the water. When faced with water sources with complex and fluctuating sediment content, simple sedimentation alone cannot adapt to the changes in different sediment concentrations and particle characteristics, resulting in a large amount of fine sediment remaining in the treated water, affecting the water quality of subsequent water use and the normal operation of related water conservancy facilities; for example, in some irrigation projects, residual sediment may clog irrigation pipes and reduce irrigation efficiency; in water supply projects, fine sediment will affect the appearance and taste of water, increasing the difficulty and cost of water purification.

[0004] In addition, the traditional sediment separation device separates sediment and water through an inclined filter screen, but the separated sediment will inevitably be mixed with more water during the collection work, and when the sediment is in the separation process, the sediment will move away from one end of the feed port, which is easy to cause sediment accumulation, which not only reduces the sediment treatment effect, but also reduces the working efficiency of the sediment separation device, affects the continuity and stability of the entire sediment treatment process, and thus reduces the practicality of the sediment separation device.

[0005] In view of this, a comprehensive sediment treatment method for water conservancy projects is urgently needed. Summary of the invention

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0019] See also Figure 1-Figure 4 As shown, the purpose of this embodiment is to provide a comprehensive sediment treatment method for a water conservancy project, comprising the following steps: Step 1: Water diversion operation: First, plan the direction and size of the water diversion channel according to the scale and purpose of the water conservancy project, and use concrete lining to reduce leakage and water flow resistance. At the same time, install trash racks at the entrance of the water diversion channel with a spacing of 3cm-9cm. Clean up debris regularly to prevent blockage and allow water to flow smoothly into subsequent treatment links; Step 2: Preliminary separation of sediment: At the end of the waterway, build a sedimentation tank with a depth of 3m-5m, a bottom slope of 1:9-1:19, and an anti-seepage wall. Then install a throttling device to control the water flow rate at 0.1m / s-0.3m / s to allow coarse sediment to settle. Then set a sediment discharge pipe at the bottom of the tank. When the sediment reaches 0.5m-1m, open the valve and use gravity to discharge the sediment. The discharged sediment can be used for filling projects or transported to designated sediment storage sites. Step 3: Fine separation of sediment: Install the feed port 11 of the sediment separation device at the water outlet of the sedimentation tank, so that water enters the interior of the sediment separation device, and is processed by the sediment separation device to finely separate the sediment. The separated sediment flows from the discharge port 12 to the interior of the transport vehicle 15, and the separated clean water flows out from the drain port 13; Step 4: Water purification: Use activated carbon filtration to filter the outflowing clean water, intercept fine particle impurities and absorb organic matter, odor and some heavy metal ions, and then disinfect the water according to its purpose. Finally, after disinfection, test the water quality, including suspended matter content, microbial indicators, and chemical oxygen demand, and then store it in a clean water tank for irrigation and water supply, and protect the clean water tank to prevent external pollution; Among them, according to Figure 2-Figure 7 As shown, the sediment separation device used in S3 also includes a housing 10 and a stand 14 for raising the transport vehicle 15. The transport vehicle 15 is raised to prevent the wheels under the transport vehicle 15 from moving at will, causing the separated sediment to be unable to be collected. A filter frame 20 is provided inside the housing 10, and Figure 2-Figure 4 It can be seen that the feed inlet 11 is located on a side away from the opening of the filter frame 20. The inner wall of the filter frame 20 is provided with a filter screen 201. The filter screen 201 is made of anti-corrosion metal material to prevent the filter screen 201 from being damaged due to long-term use. The housing 10 is provided with a pusher 40. Figure 3-Figure 6 It can be seen that the pusher 40 is located above the filter screen 201, and the pusher 40 is close to one side of the opening of the filter frame 20. The lower end of the opening of the filter frame 20 is provided with a pre-storage shell 21, and the interior of the pre-storage shell 21 is provided with an inclined plate 22 for assisting the silt to be transported inside the vehicle 15. The interior of the pre-storage shell 21 is provided with a cover plate 30. Figure 7 It can be seen that the cover plate 30 is located above the inclined plate 22, and a guide shell 23 for assisting the outflow of clean water is provided inside the housing 10; The pusher 40 can push the silt on the upper surface of the filter screen 201 to one side of the pre-storage shell 21. At the same time, the pusher 40 and the cover plate 30 squeeze and dehydrate the silt. Moreover, the cover plate 30 is opened by the accumulation of silt. At this time, the silt flows into the interior of the pre-storage shell 21, so that the silt is collected. The side of the upper end of the cover plate member 30 close to the push member 40 can block the mud and sand on the push member 40, so that an extrusion space for squeezing the mud and sand is formed between the cover plate member 30 and the push member 40.

[0020] Considering that when the pusher 40 cleans the sediment on the upper surface of the filter screen 201 near the pre-storage shell 21, the sediment may rotate with the rotation of the pusher 40, affecting the effect and efficiency of sediment treatment, therefore, according to Figure 2-Figure 9 As shown, first, the specific structure of the cover member 30 is disclosed. The cover member 30 at least includes a mounting plate 31. A plurality of mounting grooves 32 are provided inside the mounting plate 31. A first elastic member 33 is provided inside each of the plurality of mounting grooves 32. An extension plate 34 is provided at one end of the first elastic member 33 away from the mounting groove 32. A sealing member 35 is provided at one end of the extension plate 34 away from the first elastic member 33.

[0021] Next, the specific structure of the sealing member 35 is disclosed. The sealing member 35 at least includes a mounting box 351, and a plurality of second elastic members 352 are arranged inside the mounting box 351. An adjustment plate 353 is arranged at one end of the plurality of second elastic members 352 away from the bottom of the mounting box 351, and a connecting plate 354 is arranged at one end of the adjusting plate 353 away from the second elastic members 352. An auxiliary member 36 is arranged at one side of the connecting plate 354 close to the pushing member 40. The elastic force of the first elastic member 33 is greater than the elastic force of the second elastic member 352.

[0022] Then the specific structure of the auxiliary component 36 is disclosed. The auxiliary component 36 at least includes a baffle 361. The baffle 361 is an isosceles triangle, and the hypotenuse of the baffle 361 is arc-shaped. A protective plate 362 is provided on the lower surface of the baffle 361. The protective plate 362 is an isosceles triangle.

[0023] When treating sediment, the water discharged from the water outlet of the sedimentation tank flows toward the feed port 11, so that it enters the interior of the shell 10. At this time, through the inclination of the filter frame 20 and the filter screen 201, the water flows toward the opening of the filter frame 20, so that the water is finely separated. Moreover, through the height of the filter frame 20, the sediment can be prevented from sticking to the inner wall of the shell 10 during the treatment process, thereby reducing the factors affecting the sediment treatment. In addition, the water discharged from the water outlet of the sedimentation tank continuously flows into the interior of the shell 10, impacting the sediment on the upper surface of the filter screen 201 near the feed port 11, so that the sediment flows along the slope of the filter screen 201 as soon as possible. At the same time, the separated clean water will flow into the guide shell 23 through the holes of the filter screen 201, and through the special shape of the guide shell 23 (through Figure 2 It can be seen that the shape of the guide shell 23 directs water to the drain outlet 13, which facilitates the subsequent treatment of the clean water; In addition, when the separated silt flows to the side close to the opening of the filter frame 20, the silt on the filter screen 201 is pushed toward the protection plate 362 by the pusher 40, and the silt on the pusher 40 is blocked by the blocking rod 361 to prevent the silt from rotating with the rotation of the pusher 40, so that the silt is accumulated in the squeeze space; When the sediment accumulates to a certain extent, the sediment continues to accumulate, which will cause the first elastic member 33 to deform and expand. At the same time, the extension plate 34 enters the interior of the installation plate 31, and the installation box 351 is away from the filter screen 201. At the same time, the resilience of the second elastic member 352 pushes the adjustment plate 353 upward, driving the auxiliary member 36 to adjust its position, and the protective plate 362 blocks the adjustment plate 353, which can prevent the sediment from entering the interior of the installation box 351, avoiding increasing the resistance of the adjustment plate 353 to rise and fall. At the same time, the protective plate 362 can guide the flow of sediment, and the inclined surface of the protective plate 362 is made of smooth material to prevent the sediment from sticking to the inclined surface of the protective plate 362, thereby improving the flexibility of the auxiliary member 36. When the cover member 30 is opened, the separated mud and sand enter the interior of the pre-storage shell 21 through the gravity of the mud and sand itself. At the same time, through the reduction of the mud and sand in the extrusion space, the installation box 351 is close to the filter screen 201 through the resilience of the first elastic member 33. At the same time, the second elastic member 352 side is deformed and stretched until the cover member 30 is closed, so that an extrusion space is formed again to collect and squeeze the mud and sand, and prevent the mud and sand from being mixed with too much water. This not only improves the effect of mud and sand treatment, but also improves the working efficiency of the mud and sand separation device, increases the continuity and stability of the entire mud and sand treatment process, and thus improves the practicability of the mud and sand separation device.

[0024] During the use of the sediment separation device, the sediment will be far away from one end of the feed port 11, which is easy to cause sediment accumulation, which not only reduces the effect of sediment treatment, but also reduces the working efficiency of the sediment separation device. Figure 2-Figure 7 As shown, the specific structure of the pusher 40 is disclosed. The pusher 40 at least includes a rotating cylinder 41. The rotating shafts at both ends of the rotating cylinder 41 are rotatably connected to the inner wall of the housing 10. The outer wall of the rotating cylinder 41 is provided with a plurality of grooves 42. One end of the opening of the plurality of grooves 42 is connected to a scraper 43 through an automatic reset hinge. An elastic sealing strip 44 is provided on one side of the opening of the groove 42 away from the scraper 43. One end of the elastic sealing strip 44 away from the groove 42 is fixedly connected to the side of the scraper 43.

[0025] The motor (the motor is not shown in the figure due to the angle of the attached figure) is powered on to make it work. The motor output shaft rotates to drive the rotating drum 41 to rotate. At the same time, when the scraper 43 contacts the upper surface of the filter screen 201, the silt will be pushed toward the protective plate 362 as the rotating drum 41 rotates, so that the silt is temporarily accumulated in the extrusion space, which is convenient for squeezing the separated silt, reducing the water content in the silt, and facilitating the subsequent treatment of the separated silt. In addition, when the scraper 43 contacts the end of the lower surface of the blocking rod 361 away from the connecting plate 354, the elastic force of the first elastic member 33 is greater than the elastic force of the spring in the automatic reset hinge, so that the scraper 43 enters the interior of the groove 42. At the same time, the elastic sealing strip 44 is also deformed, and the silt on the scraper 43 is cleaned through the inclined surface of the protective plate 362 to prevent the silt from rotating with the rotation of the rotating drum 41. This not only reduces the factors affecting the use effect of the silt separation device, but also reduces the frequency of failure of the silt separation device, thereby increasing the service life of the silt separation device. Afterwards, when the scraper 43 is away from the protective plate 362, the rebound force of the spring in the automatic reset hinge pops the scraper 43 out of the groove 42, so that when the scraper 43 passes through the filter 201, it is convenient to push the mud on the upper surface of the filter 201. At the same time, the elastic sealing strip 44 is also deformed. The elastic sealing strip 44 can effectively prevent mud from entering the groove 42, reduce the factors affecting the failure of the pusher 40, and increase the service life of the pusher 40. It not only improves the working efficiency of the mud separation device in mud treatment, but also improves the stability of the use of the mud separation device, thereby improving the reliability and effectiveness of the comprehensive mud treatment system of the entire water conservancy project.

[0026] In summary, the working principle of the sediment separation device in this scheme is as follows: first, the water discharged from the outlet end of the sedimentation tank flows to the feed port 11, so that it enters the interior of the shell 10. At this time, the water flows to the opening of the filter frame 20 through the inclination of the filter frame 20 and the filter screen 201. In this process, the water will flow downward through the holes of the filter screen 201, and the water will flow to the drain port 13 through the guide shell 23. The separated sediment will flow laterally to the opening of the filter frame 20. At the same time, the motor is powered on to make it work, and the rotating cylinder 41 is driven to rotate through the rotation of the motor output shaft. At the same time, when the scraper 43 contacts the upper surface of the filter screen 201, it will push the sediment to the protective plate 362 as the rotating cylinder 41 rotates, so that the sediment is temporarily accumulated in the extrusion space; Then, when the sediment accumulates to a certain extent, the sediment continues to accumulate, which will cause the first elastic member 33 to deform and expand. At the same time, the extension plate 34 enters the interior of the mounting plate 31, and the mounting box 351 is away from the filter screen 201. At the same time, the resilience of the second elastic member 352 pushes the adjustment plate 353 upward, driving the auxiliary member 36 to adjust its position, so that the cover member 30 is in an open state, and the separated sediment enters the interior of the pre-storage shell 21 through the gravity of the sediment itself. At the same time, through the reduction of the sediment in the extrusion space, the mounting box 351 is close to the filter screen 201 through the resilience of the first elastic member 33. At the same time, the second elastic member 352 side is deformed and expanded until the cover member 30 is closed, so that it forms an extrusion space again. However, through the inclination of the inclined plate 22, the sediment flows out of the interior of the pre-storage shell 21 from the discharge port 12 and enters the interior of the transport vehicle 15 through the discharge port 12, thereby completing the use of the sediment separation device.
