[0002] With the acceleration of modern urbanization and industrialization, water pollution seriously threatens the quality of life and health of residents, restricts the development of cities, and damages the beautiful image of cities. Therefore, the treatment of sewage plays a vital role in improving people's quality of life and ensuring their health.

[0003] While existing water treatment devices meet users' needs to some extent, they still have certain shortcomings. Specifically, these devices often have limited functionality and lack the ability to comprehensively treat different types of garbage and impurities. They cannot achieve multi-level treatment of river sewage. Some treatment methods only target surface garbage removal, ignoring the long-term impact of riverbed silt on water quality. Furthermore, some dredging measures fail to effectively combine with surface garbage removal, making it impossible to comprehensively address river pollution from multiple perspectives. This makes it difficult for rivers to restore their self-purification capacity, hinders the ecosystem from achieving balance and stability, results in unsustainable treatment effects, and makes it difficult to fundamentally improve the river's ecological environment.

An extrusion head is fixed to one side of the receiving plate, and an extrusion switch is hinged to the side of the support frame near the extrusion head.

[0016] This invention also provides a device and method for ecological restoration and treatment of river sewage, comprising the following steps:

[0017] S1. When it is necessary to repair and treat river sewage, the garbage and impurities in the river sewage are intercepted by the interception filter. As the treatment work is carried out, the garbage and impurities intercepted in front of the interception filter will gradually accumulate, which will cause the water level in front of the interception filter and inside the water outlet channel to change. This will cause the floating ball to rise and fall with the water level, and cause the swing frame to rotate around its hinge point with the interception filter. Then, it will press and trigger the squeeze switch one, and then automatically start the drive motor, thereby driving the sludge pusher and mud pusher to move in opposite directions, realizing the cleaning of different types of garbage and impurities in the river sewage.

[0018] S2. By moving the sludge pusher and the mud pusher, the sewage discharge channel and the mud discharge channel can be opened in sequence, so that garbage and sludge can be pushed out of the sewage discharge trough and the mud discharge trough respectively, ensuring the order of sewage discharge first and sludge discharge later, and avoiding the mixed discharge of garbage and sludge.

[0019] S3. The discharged sewage, along with garbage and impurities, will fall onto the stripping screen inside the screening box, which will separate the garbage and sewage. The garbage and impurities will remain on the stripping screen, while the sewage will enter the water channel at the bottom of the screening box through the stripping screen and return to the river body.

[0020] S4. Through the rotation of the bidirectional reciprocating screw, with the cooperation of the timing belt, the rotating shaft can be driven to rotate, which in turn drives the rotating frame and the stripping rack to rotate. This can drive the garbage and impurities remaining on the stripping screen toward the sewage hopper, and finally dewater them and discharge them from the sewage hopper.

[0021] S5. By opening the sludge discharge channel, sludge and sewage will fall into the conveying cylinder at the bottom of the screening box. When the rotating shaft rotates, the chain drives the spiral auger to rotate, and the sludge in the screening box is discharged through the sludge discharge pipe.

[0022] S6. The garbage and impurities discharged from the sewage hopper will fall onto the conveyor belt. The conveyor belt transports the dewatered and screened garbage and impurities. The push plate moves downward under the drive of the electric telescopic rod, which in turn drives the extrusion sleeve and extrusion strip to move synchronously. When the extrusion strip contacts the garbage and impurities on the conveyor belt, the extrusion strip squeezes the garbage and impurities. If the garbage and impurities transported are hard impurities, the pressure change generated will be fed back to the pressure sensor. Then the pressure sensor controls the electric telescopic rod to stop moving through the controller. Then the hard garbage and impurities continue to move with the conveyor belt and are output from the guide hopper.

[0023] S7. If the conveyed waste and impurities are flexible, the pressure sensor will not receive feedback on pressure changes. Eventually, the lever will move along the vertical section of the track groove to the bottom of the inclined section, causing the receiving plate to rotate, which in turn triggers the second squeezing switch. The electric push rod starts, driving the baffle plate to rotate and push the flexible waste and impurities into the guide hopper one for output.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use.

[0025] 1. Equipped with interception components, it can clean up different types of garbage and impurities (surface garbage and riverbed silt) in river sewage, complete multi-level restoration and treatment of river sewage, solve river pollution problems from multiple levels, comprehensively improve the river ecological environment, help restore the river's self-purification capacity, and promote the balance and stability of the river ecosystem.

[0026] By using the pusher plate, the debris and impurities intercepted by the filter screen can be pushed towards one side of the sealing plate, which can promptly and accurately detect the clogging of the filter screen. This greatly improves the timeliness and accuracy of monitoring the operation status of the treatment device, eliminating the need for constant manual monitoring and operation. It significantly improves the efficiency and timeliness of cleaning, reduces labor costs, and achieves automatic cleaning after the filter screen becomes clogged. This ensures the continuous and stable operation of the treatment device and greatly improves the efficiency of river sewage treatment.

[0027] 2. Equipped with a stripping component, it can more thoroughly separate garbage and impurities from sewage and further dehydrate the garbage and impurities, enhancing the treatment effect of garbage and impurities, avoiding secondary pollution that may be caused by garbage and impurities with high water content in subsequent treatment, optimizing the garbage and impurity treatment process, ensuring the cleanliness and hygiene of the surrounding environment of the river, helping to improve the quality and effectiveness of river management, and facilitating the targeted treatment and resource utilization of garbage and impurities in the future.

[0028] By using a stripping net, the screened wastewater can be returned to the river body through the water diversion channel, realizing the recycling of water resources, reducing water waste caused by improper wastewater treatment, improving the efficiency of water resource utilization, reducing dependence on external clean water sources, alleviating the pressure on wastewater treatment, and providing a strong guarantee for the water resource balance of the river ecosystem.

[0029] 3. Equipped with sorting components, it can accurately distinguish between hard and soft waste and impurities, enabling the classification and treatment of different types of waste and impurities. This provides a strong guarantee for the targeted treatment of different types of waste in the future. While controlling river pollution, it maximizes the utilization of resources and improves environmental benefits, making the waste treatment process in river sewage treatment more efficient and faster, and improving the overall treatment effect.

[0051] This invention also provides a device and method for ecological restoration and treatment of river sewage, comprising the following steps:

[0052] S1. When it is necessary to repair and treat river sewage, the intercepting filter 21 intercepts garbage and impurities in the river sewage. As the treatment work progresses, the garbage and impurities intercepted in front of the intercepting filter 21 will gradually accumulate, thereby changing the water level in front of the intercepting filter 21 and inside the water outlet channel 22. This causes the floating ball 26 to rise and fall with the water level, and the swing frame 23 to rotate around its hinge point with the intercepting filter 21. This causes the frame to press and trigger the squeeze switch 29, and then automatically start the drive motor 211, thereby driving the sludge pusher 212 and the mud pusher 213 to move in opposite directions or in opposite directions, thus cleaning up different types of garbage and impurities in the river sewage.

[0053] S2. By moving the sludge pusher 212 and the mud pusher 213, the sewage discharge channel and the mud discharge channel can be opened in sequence, so that garbage and sludge can be pushed out of the sewage discharge trough and the mud discharge trough respectively, ensuring the order of sewage discharge first and sludge discharge later, and avoiding the mixed discharge of garbage and sludge.

[0054] S3. The discharged sewage and garbage will fall onto the stripping screen 32 inside the screening box 31, which can separate the garbage and sewage. The garbage will remain on the stripping screen 32, and the sewage will enter the water channel at the bottom of the screening box 31 through the stripping screen 32 and return to the river body 1.

[0055] S4. By rotating the bidirectional reciprocating screw 210, in coordination with the timing belt 311, the rotating shaft 33 can be driven to rotate, which in turn drives the rotating frame 34 and the stripping rack 35 to rotate. This causes the garbage and impurities remaining on the stripping net 32 ​​to move towards the sewage hopper 314, and finally dehydrate and be discharged from the sewage hopper 314.

[0056] S5. By opening the sludge discharge channel, sludge and sewage will fall into the conveying cylinder 312 at the bottom of the screening box 31. When the rotating shaft 33 rotates, the spiral auger 313 will be driven to rotate by the chain 36, and the sludge in the screening box 31 will be discharged through the sludge discharge pipe.

[0057] S6. The garbage and impurities discharged from the sewage hopper 314 will fall onto the conveyor belt 43. The conveyor belt 43 transports the dewatered and screened garbage and impurities. The push plate 47 moves downward under the drive of the electric telescopic rod 46, which in turn drives the extrusion sleeve 48 and the extrusion strip 49 to move synchronously. When the extrusion strip 49 contacts the garbage and impurities on the conveyor belt 43, the extrusion strip 49 extrudes the garbage and impurities. If the garbage and impurities transported are hard impurities, the pressure change generated will be fed back to the pressure sensor 411. Then the pressure sensor 411 controls the electric telescopic rod 46 to stop moving through the controller. Then the hard garbage and impurities continue to move with the conveyor belt 43 and are output from the guide hopper 2 422.

[0058] S7. If the conveyed waste and impurities are flexible, the pressure sensor 411 will not receive feedback on pressure changes. Finally, the lever 412 will move along the vertical section of the track groove 414 to the bottom of the inclined section, thereby causing the receiving plate 413 to rotate, which in turn triggers the second squeezing switch 416. The electric push rod 417 starts, driving the baffle plate 420 to rotate and push the flexible waste and impurities into the first guide hopper 421 for output.

[0059] The working principle and usage process of this invention are as follows: When it is necessary to repair and treat river sewage, the intercepting filter 21 intercepts garbage and impurities in the river sewage. After being filtered by the intercepting filter 21, the sewage continues to flow in the river body 1 through the outlet channel 22. As the treatment work progresses, the garbage and impurities intercepted in front of the intercepting filter 21 will gradually accumulate, resulting in a reduction in the amount of purified sewage flowing out through the outlet channel 22. This causes a change in the water level in front of the intercepting filter 21 and inside the outlet channel 22, thus allowing the intercepting filter to be filtered. The floating ball 26 in front of the filter screen 21 rises with the water level, while the floating ball 26 in the outlet channel 22 falls with the water level. When the floating ball 26 in front of the filter screen 21 rises with the water level, it drives the swing frame 23 to rotate around its hinge point with the filter screen 21 via the push-pull rod 25 and the hinge rod 24. When the swing frame 23 swings to a certain position, it can press and trigger the squeeze switch 29. After the squeeze switch 29 is triggered and opened, the drive motor 211 starts, driving the bidirectional reciprocating screw 210 to rotate. The pusher plates 212 on both sides of the surface move in opposite directions under the action of the threads, thereby driving the pusher plate 213 to move synchronously. With the movement of the pusher plates 212, the garbage and impurities intercepted by the intercepting filter 21 can be pushed towards one side of the sealing plate 215, which can detect the blockage of the intercepting filter 21 in a timely and accurate manner, greatly improving the timeliness and accuracy of the monitoring of the operation status of the treatment device. There is no need for constant monitoring and manual operation, which greatly improves the cleaning efficiency and timeliness, reduces labor costs, realizes automatic cleaning after the intercepting filter 21 is blocked, ensures the continuous and stable operation of the treatment device, and greatly improves the work efficiency of river sewage treatment. Then, the movement of the pusher plate 213 can push the silt accumulated on the front side of the intercepting filter 21 towards the sealing plate 217, realizing the cleaning of different types of garbage and impurities in the river sewage, completing the multi-level repair and treatment of river sewage, solving the river pollution problem from multiple levels, comprehensively improving the river ecological environment, helping to restore the river's self-purification capacity, and promoting the balance and stability of the river ecosystem.

[0060] Furthermore, through the movement of the sludge pusher 212 and the mud pusher 213, the pusher column 214 on the side of the sludge pusher 212 closest to the sealing plate 215 first contacts and pushes the sealing plate 215, causing it to overcome the elastic force of the spring 220 and slide open the discharge channel in the discharge trough, thus pushing out the garbage and impurities. The pusher column 216 on the side of the mud pusher 213 closest to the sealing plate 217 then contacts and pushes the sealing plate 217, causing it to slide open the sludge discharge channel in the sludge discharge trough, pushing the sludge into the sludge discharge trough. Since the length of the pusher column 214 is greater than that of the pusher column 216... This ensures the order of discharging sewage before sludge, avoiding the mixed discharge of garbage and sludge, making the subsequent classification and treatment of garbage and sludge more convenient and efficient, improving the rationality and smoothness of the overall treatment process, and helping to treat different types of garbage and impurities in a targeted manner. It can effectively improve the treatment effect of river sewage, better improve the river ecological environment, and promote the restoration and healthy development of the river ecosystem. The positioning rod 218 and the positioning frame 219 work together to make the sealing plate 215 and the sealing plate 217 slide stably, and the spring 220 resets the sealing plate after the sewage is pushed.

[0061] Furthermore, by opening the sewage discharge channel, sewage along with garbage and impurities will be pushed out of the discharge trough and then fall onto the stripping screen 32 inside the screening box 31. The stripping screen 32 separates and separates the garbage and sewage, leaving the garbage on it while the sewage flows through the screen into the water channel at the bottom of the screening box 31 back to the river body 1. This achieves water resource recycling, reduces water waste caused by improper sewage treatment, improves water resource utilization efficiency, reduces dependence on external clean water sources, alleviates the pressure on sewage treatment, and provides strong protection for the water resource balance of the river ecosystem. With the rotation of the bidirectional reciprocating screw 210, in conjunction with the synchronous belt 311, the drive shaft 310 is driven to rotate. The drive shaft 310, through the bevel gear pair 39, drives... The transmission rod 38 rotates, which in turn drives the rotating shaft 33 to rotate via the bevel gear pair 37. The rotating shaft 33 then drives the rotating frame 34 and the stripping rack 35 to rotate. The stripping rack 35 is adapted to the mesh groove inside the stripping net 32, which can drive the garbage and impurities remaining on the stripping net 32 ​​toward the sewage discharge hopper 314. After dehydration, the garbage and impurities are discharged from the sewage discharge hopper 314. This can more thoroughly separate the garbage and impurities from the sewage and further dehydrate them, thus enhancing the treatment effect. It avoids secondary pollution that may be caused by garbage and impurities with high water content in subsequent treatment, optimizes the garbage and impurity treatment process, ensures the cleanliness and hygiene of the surrounding environment of the river, helps to improve the quality and effectiveness of river management, and facilitates the targeted treatment and resource utilization of garbage and impurities in the future.

[0062] It is worth noting that, similarly, by opening the sludge discharge channel, sludge and sewage will fall into the conveying cylinder 312 at the bottom of the screening box 31. When the rotating shaft 33 rotates, the chain 36 drives the spiral auger 313 to rotate, and the sludge in the screening box 31 is discharged through the sludge discharge pipe.

[0063] Furthermore, the waste and impurities discharged from the sewage hopper 314 fall onto the conveyor belt 43. When the rotating shaft 33 rotates, it drives the drive roller shaft 42 to rotate via the chain 44, thereby driving the conveyor belt 43 to operate within the sorting conveyor frame 41, thus conveying the dewatered and screened waste and impurities. As the waste and impurities move on the conveyor belt 43, the push plate 47 moves downward under the drive of the electric telescopic rod 46, thereby driving the extrusion sleeve 48 and the extrusion strip 49 to move synchronously. When the extrusion strip 49 contacts the waste and impurities on the conveyor belt 43, the extrusion strip 49 extrudes the waste and impurities. During this process, the lever 412 moves downward synchronously with the extrusion strip 49. If the conveyed waste and impurities are hard impurities, the extrusion strip 49 will be obstructed during the process of pressing down on the waste and impurities, and the spring 410 will be compressed. The resulting pressure change will be fed back to the pressure sensor 411. Subsequently, the pressure sensor 411 controls the electric telescopic rod 46 to stop its operation through the controller. Then, the hard waste and impurities continue to move with the conveyor belt 43, from the guide hopper 422. If the delivered waste is flexible, the extrusion bar 49 will not be obstructed during the pressing process, and the spring 410 will not be compressed. Therefore, the pressure sensor 411 will not receive feedback on pressure changes. Finally, the lever 412 will move along the vertical section of the track groove 414 to the bottom of the inclined section, causing the plate 413 to rotate. The extrusion head 415 on the plate will then press and trigger the extrusion switch 416. After the extrusion switch 416 is triggered, the electric push rod 417 will start, driving the lever 418 to rotate around the rotating rod 419. The baffle plate 420 will rotate to push the flexible waste into the guide hopper 421 for classification. This can accurately distinguish between hard and flexible waste, achieving classified treatment of different types of waste. This provides a strong guarantee for the targeted treatment of different types of waste in the future. While controlling river pollution, it maximizes resource utilization and improves environmental benefits, making the waste treatment process in river sewage treatment more efficient and faster, and improving the overall treatment effect.

7. A method of using the river wastewater ecological restoration and treatment device according to any one of claims 1-6, characterized in that: Includes the following steps: S1. When it is necessary to repair and treat river sewage, the garbage and impurities in the river sewage are intercepted by the interception filter. As the treatment work is carried out, the garbage and impurities intercepted in front of the interception filter will gradually accumulate, which will cause the water level in front of the interception filter and inside the water outlet channel to change. This will cause the floating ball to rise and fall with the water level, and cause the swing frame to rotate around its hinge point with the interception filter. Then, it will press and trigger the squeeze switch one, and then automatically start the drive motor, thereby driving the sludge pusher and mud pusher to move in opposite directions, realizing the cleaning of different types of garbage and impurities in the river sewage. S2. By moving the sludge pusher and the mud pusher, the sewage discharge channel and the mud discharge channel can be opened in sequence, so that garbage and sludge can be pushed out of the sewage discharge trough and the mud discharge trough respectively, ensuring the order of sewage discharge first and sludge discharge later, and avoiding the mixed discharge of garbage and sludge. S3. The discharged sewage, along with garbage and impurities, will fall onto the stripping screen inside the screening box, which will separate the garbage and sewage. The garbage and impurities will remain on the stripping screen, while the sewage will enter the water channel at the bottom of the screening box through the stripping screen and return to the river body. S4. Through the rotation of the bidirectional reciprocating screw, with the cooperation of the synchronous belt, the rotating shaft can be driven to rotate, which in turn drives the rotating frame and the stripping rack to rotate. This can drive the garbage and impurities remaining on the stripping screen to approach the sewage hopper, and finally dehydrate and be discharged from the sewage hopper. S5. By opening the sludge discharge channel, sludge and sewage will fall into the conveying cylinder at the bottom of the screening box. When the rotating shaft rotates, the chain drives the spiral auger to rotate, and the sludge in the screening box is discharged through the sludge discharge pipe. S6. The garbage and impurities discharged from the sewage hopper will fall onto the conveyor belt. The conveyor belt transports the dewatered and screened garbage and impurities. The push plate moves downward under the drive of the electric telescopic rod, which in turn drives the extrusion sleeve and extrusion strip to move synchronously. When the extrusion strip contacts the garbage and impurities on the conveyor belt, the extrusion strip squeezes the garbage and impurities. If the garbage and impurities transported are hard impurities, the pressure change generated will be fed back to the pressure sensor. Then the pressure sensor controls the electric telescopic rod to stop moving through the controller. Then the hard garbage and impurities continue to move with the conveyor belt and are output from the guide hopper. S7. If the conveyed waste and impurities are flexible, the pressure sensor will not receive feedback on pressure changes. Eventually, the lever will move along the vertical section of the track groove to the bottom of the inclined section, causing the receiving plate to rotate, which in turn triggers the second squeezing switch. The electric push rod starts, driving the baffle plate to rotate and push the flexible waste and impurities into the guide hopper one for output.
