[0044] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0045] See Figures 1-3 This invention illustrates a preferred embodiment of a radial flow sedimentation system, which includes a radial flow sedimentation tank and a cleaning device. The radial flow sedimentation tank has a sedimentation tank body 30 and an outlet channel 40. The sedimentation tank body 30 has a sedimentation tank 301, and the outlet channel 40 has an outlet trough 401. The cleaning device is used for mechanical cleaning and hydraulic rinsing of the inner wall of the outlet channel 40. The cleaning device includes:

[0046] Drive mechanism 1 is mounted on sedimentation tank body 30;

[0047] Cleaning component 2 is connected to the output end of drive mechanism 1. Cleaning component 2 can rotate along the water outlet channel 40 as drive mechanism 1 rotates. Cleaning component 2 contacts the inner wall of water outlet channel 40 and is used to clean the inner wall of water outlet channel 40.

[0048] A flushing nozzle 3 is connected to the output end of the drive mechanism 1. The flushing nozzle 3 can rotate circumferentially along the water outlet channel 40 as the output end of the drive mechanism 1 rotates. The outlet of the flushing nozzle 3 faces the inner wall of the water outlet channel 40 so as to spray clean water onto the inner wall of the water outlet channel 40.

[0049] The conveying component 4 is connected to the output end of the drive mechanism 1. The conveying component 4 can rotate along the sedimentation tank 301 in a circumferential direction as the output end of the drive mechanism 1 rotates. The inlet of the conveying component 4 is connected to the sedimentation tank 301, and the outlet of the conveying component 4 is connected to the flushing nozzle 3. The conveying component 4 is used to draw clean water located in the sedimentation tank 301 to the flushing nozzle 3.

[0050] The cleaning device of this utility model integrates a drive mechanism 1, a cleaning component 2, a rinsing nozzle 3, and a conveying component 4 to achieve automatic mechanical cleaning and hydraulic rinsing of the inner wall of the outlet channel 40, which greatly improves cleaning efficiency, effectively inhibits dirt accumulation and biofilm formation, significantly improves the quality of the effluent and the appearance of the pool, and completely replaces the traditional manual cleaning method. While reducing the labor intensity of maintenance personnel, it significantly improves the continuous operation efficiency of the radial flow sedimentation system.

[0051] Specifically, during the cleaning operation, the drive mechanism 1 drives the conveying component 4 to move circumferentially within the sedimentation tank 301, simultaneously driving the flushing nozzle 3 and the cleaning component 2 to move in a circular motion along the inner wall of the outlet channel 40. The conveying component 4 intercepts clean water in real time and precisely delivers it to the flushing nozzle 3. The high-pressure fan-shaped water jet from the flushing nozzle 3 fully covers the inner wall of the outlet channel 40, powerfully flushing away large particles of pollutants and loose sediments. This reduces the mechanical cleaning load and extends the service life of the cleaning component 2, while effectively covering blind spots in mechanical cleaning. The cooperating cleaning component 2, through close-contact mechanical cleaning, thoroughly removes stubborn residues after water rinsing. Combined with the synergistic effect of centrifugal force and high-pressure water flow, it ensures that the sloughed-off dirt is quickly carried away, preventing secondary deposition and water pollution. This synergistic cleaning mechanism combining hydraulic flushing and mechanical cleaning not only significantly improves cleaning efficiency and effectively inhibits dirt accumulation and biofilm formation, resulting in a marked improvement in effluent quality and tank appearance, but also completely replaces traditional manual cleaning methods. This reduces the workload of maintenance personnel while significantly enhancing the continuous operating efficiency of the radial flow sedimentation system. Furthermore, the dynamic superposition effect of hydraulic and mechanical actions during rotation allows for repeated cleaning of the inner wall of the effluent channel 40, further enhancing the overall cleaning effect.

[0052] It is understandable that the inner wall of the water outlet channel 40, that is, the inner wall of the water outlet trough 401, can be any one or a combination of the inner side wall, bottom wall, and outer side wall of the water outlet trough 401.

[0053] See Figure 2 In one embodiment, the cleaning component 2 is located on the side near the inner wall of the water outlet tank 401. The cleaning component 2 is used to clean the inner wall of the water outlet tank 401. The inner wall of the water outlet tank 401 is located on the side near the sedimentation tank 301. In practical applications, since the clarified water needs to overflow the water outlet channel 40, and the inner wall of the water outlet tank 401 is the surface that comes into frequent contact with the water, algae and suspended matter are easily attached and accumulated on the inner wall of the water outlet tank 401. Therefore, it is usually necessary to clean the inner wall of the water outlet tank 401.

[0054] Of course, in other embodiments, the cleaning component 2 can be used to thoroughly clean the inner wall, bottom wall and outer wall of the water outlet tank 401, in which case the cleaning component 2 fully covers the inner wall of the water outlet tank 401.

[0055] In one embodiment, the cleaning component 2 can be a cleaning brush. In this way, using a cleaning brush as the cleaning component 2 can effectively remove dirt from the inner wall of the water channel 40. The structure is simple and easy to maintain. At the same time, the material and arrangement of the brush body can be adjusted according to actual needs to improve the cleaning effect and adaptability.

[0056] Of course, in other embodiments, the cleaning component 2 may also be a cleaning scraper, which adopts a rigid or flexible scraper structure to remove dirt from the inner wall of the water outlet channel 40 by scraping.

[0057] In one embodiment, the conveying component 4 is a pump body. Thus, by using a pump body as the conveying component 4, clean water can be conveyed efficiently and stably, ensuring continuous and reliable transmission efficiency. At the same time, the flow rate and pressure can be adjusted according to the working conditions, making it highly adaptable and easy to integrate into existing systems.

[0058] Of course, in other embodiments, the conveying component 4 can also be a vacuum suction device, which can also deliver clean water to the rinsing nozzle 3 by drawing clean water through negative pressure.

[0059] See Figure 2 In one embodiment, the flushing nozzle 3 is located on the side close to the cleaning component 2, so as to achieve a spatially integrated layout of the flushing nozzle 3 and the cleaning component 2. That is, the flushing nozzle 3 and the cleaning component 2 are adjacent to each other. The proximity design enables the immediate coordination of water flushing and mechanical cleaning functions. The water flow impact and mechanical scraping form a superimposed composite cleaning effect, which can greatly improve the cleaning efficiency. Secondly, the proximity design ensures that the flushing water flow directly acts on the channel wall area that has just been scraped, which can not only wash away the stripped dirt immediately, but also prevent secondary adhesion. This spatial correlation design makes the two cleaning methods produce a synergistic cleaning effect. In addition, the integrated layout reduces the rotation radius, which can reduce the driving torque requirement.

[0060] In one embodiment, the flushing nozzle 3 is connected to the conveying component 4 via a conveying pipe. The flushing nozzle 3 is movably mounted on the conveying pipe, allowing the outlet direction of the flushing nozzle 3 to be adjustable. Thus, because the flushing nozzle 3 is movably mounted on the conveying pipe, it forms an adjustable structure, ensuring that the flushing angle can be dynamically adjusted according to the actual dirt accumulation, significantly improving its adaptability to different working conditions. Secondly, the adjustable flushing nozzle 3 allows for precise control of the flushing direction, concentrating the water flow impact force on stubborn dirt areas, greatly improving the cleaning efficiency per unit water flow compared to a fixed flushing nozzle 3.

[0061] The movable connection between the flushing nozzle 3 and the delivery pipeline can be achieved in any of the following ways:

[0062] Ball joint type:

[0063] The flushing nozzle 3 is equipped with a ball joint, which is movably mounted on the aforementioned conveying pipe to ensure that the flushing nozzle 3 can move relative to the conveying pipe; at the same time, a locking element is provided on the flushing nozzle 3 or the conveying pipe to fix the angle of the flushing nozzle 3.

[0064] Universal joint connection type:

[0065] The flushing nozzle 3 is equipped with a universal joint structure, which is movably mounted on the aforementioned conveying pipe to ensure that the flushing nozzle 3 can move relative to the conveying pipe; at the same time, a locking element is provided on the flushing nozzle 3 or the conveying pipe to fix the angle of the flushing nozzle 3.

[0066] Flexible hose connection type:

[0067] The flushing nozzle 3 is connected to the conveying pipe through a pressure-resistant corrugated pipe. At the same time, a magnetic positioning mechanism is configured on the flushing nozzle 3, which works with the conveying pipe to achieve positioning.

[0068] See Figure 2 In one embodiment, the outlet of the rinsing nozzle 3 is positioned towards the cleaning component 2. By positioning the outlet of the rinsing nozzle 3 towards the cleaning component 2, which contacts the inner wall of the water outlet channel 40, i.e., the rinsing nozzle 3 indirectly faces the inner wall of the water outlet channel 40, the rinsing water flows through the cleaning component 2 and indirectly acts on the area in contact with the inner wall of the water outlet channel 40, forming a synergistic effect of hydraulic flushing and mechanical cleaning. This not only enhances the removal effect on stubborn deposits but also realizes the self-cleaning function of the cleaning component 2. At the same time, it optimizes the water flow path to eliminate cleaning dead corners, thereby significantly improving the self-maintenance capability of the radial flow sedimentation system and extending the service life of the cleaning assembly consisting of the cleaning component 2, the rinsing nozzle 3, and the conveying component 4.

[0069] See Figure 2 In one embodiment, the rinsing nozzle 3 is located above the cleaning component 2. By positioning the rinsing nozzle 3 above the cleaning component 2, the rinsing water flow naturally covers the contact surface between the cleaning component 2 and the inner wall of the water outlet channel 40 under the action of gravity, forming a three-dimensional rinsing effect from top to bottom. This not only enhances the water flow's penetration and cleaning ability on the cleaning component 2 but also improves the utilization rate of the rinsing water flow. At the same time, it avoids the splashing problem that may occur with traditional side rinsing, thereby optimizing system energy consumption and improving operational stability while ensuring the cleaning effect.

[0070] See Figures 1-2, in one embodiment, the cleaning device for the radial flow sedimentation tank further includes:

[0071] A scum scraping component 5, the scum scraping component 5 is connected to the output end of the driving mechanism 1, and the scum scraping component 5 can move circumferentially along the sedimentation tank 301 as the output end of the driving mechanism 1 rotates. The scum scraping component 5 is used to gather the surface scum in the sedimentation tank 301 and push the gathered surface scum to the slag discharging device 50 on the sedimentation tank body 30. By driving the scum scraping component 5 to move circumferentially along the sedimentation tank 301 through the driving mechanism 1, the scum scraping component 5 can push the surface scum in the sedimentation tank 301 to rotate and gather the surface scum at a preset slag discharging position (such as the slag discharging device 50 supporting the sedimentation tank body 30), which is convenient for timely removing the surface scum in the sedimentation tank 301, preventing the surface scum from overflowing into the water outlet channel 40 along with the clear water in the sedimentation tank 301, and ensuring the water quality of the outlet. In this way, when the scum scraping component 5 rotates, the first scum scraping part 51 realizes the efficient gathering of the surface scum in the sedimentation tank 301. At the same time, when the first scum scraping part 51 rotates, the surface scum moves outward under the action of centrifugal force. When the first scum scraping part 51 pushes the scum to the edge of the sedimentation tank 301, the second scum scraping part 53 that can swing up and down can form an inclined diversion surface to accurately guide the scum into the slag discharging device 50, avoiding the accumulation and blockage of the scum at the corner. Therefore, the first scum scraping part 51 and the second scum scraping part 53 cooperate and联动 through the connecting component 52 to ensure the comprehensiveness of scum cleaning. Among them, since the second scum scraping part 53 can swing up and down, the second scum scraping part 53 can swing freely with the liquid level height, so that the second scum scraping part 53 always maintains the best contact angle with the liquid level, avoiding the problems of scum scraping failure or slag leakage caused by the change of the liquid level, and significantly improving the working condition adaptability; secondly, the second scum scraping part 53 that can swing up and down can buffer the rigid collision with the scum layer during the scum scraping process, which can not only ensure sufficient scraping force, but also prevent the secondary diffusion of the scum or the deformation and damage of the components caused by excessive pressure, and prolong the service life of the second scum scraping part 53; in addition, during the scum scraping process, the pivot structure can automatically adjust the fitting degree between the second scum scraping part 53 and the side wall of the sedimentation tank 301, effectively reducing the escape of the scum from the edge of the second scum scraping part 53 and improving the scum collection rate.

[0072] In one embodiment, the scum scraping component 5 includes:

[0073] A first scum scraping part 51, the first scum scraping part 51 is connected to the output end of the driving mechanism 1, the first scum scraping part 51 is horizontally placed in the sedimentation tank 301, and the first scum scraping part 51 is used to push and gather the surface scum in the sedimentation tank 301;

[0074] A connecting component 52, the connecting component 52 is arranged on the top of the first scum scraping part 51; and

[0075] The second scraper component 53 is pivotally connected at its upper end to the connecting component 52, allowing it to swing up and down. Located near the vertical center of the first scraper component 51 away from the sedimentation tank, the second scraper component 53 scrapes away surface scum collected by the first scraper component 51 and directs it to the scum discharge device 50 within the sedimentation tank 301. Thus, when the scraper assembly 5 rotates, the first scraper component 51 efficiently collects surface scum within the sedimentation tank 301. Simultaneously, as the first scraper component 51 rotates, the surface scum moves outward under centrifugal force. When the first scraper component 51 pushes the scum to the edge of the sedimentation tank 301, the swinging second scraper component 53 forms an inclined guide surface, precisely guiding the scum into the scum discharge device 50, preventing scum buildup and blockage at corners. Therefore, the coordinated operation of the first scraper component 51 and the second scraper component 53 through the connecting component 52 ensures comprehensive scum removal. Among these features, the second scraper component 53 can swing up and down, allowing it to move freely with the liquid level. This ensures that the second scraper component 53 always maintains the optimal contact angle with the liquid surface, preventing scraping failure or leakage due to changes in liquid level and significantly improving its adaptability to different operating conditions. Secondly, the up-and-down swinging second scraper component 53 can buffer the rigid collision with the scum layer during scraping, ensuring sufficient scraping force while preventing secondary diffusion of scum or component deformation and damage due to excessive pressure, thus extending the service life of the second scraper component 53. Furthermore, during the scraping process, the pivot structure can automatically adjust the fit between the second scraper component 53 and the side wall of the sedimentation tank 301, effectively reducing the escape of scum from the edge of the second scraper component 53 and improving the scum collection rate.

[0076] In one embodiment, the cleaning component 2, the rinsing nozzle 3, and the conveying component 4 are all mounted on the scraper assembly 5. In this way, the scraper assembly 5 serves as the core load-bearing structure, integrating the drive mechanism 1 with the cleaning component 2, the rinsing nozzle 3, and the conveying component 4 into a modular structure, which can improve the rigidity and operational stability of the overall structure. Secondly, the standardized interface design of the scraper assembly 5 enables quick assembly and disassembly of the cleaning component 2, the rinsing nozzle 3, and the conveying component 4, reducing the difficulty of maintenance operations. Thirdly, the rigid structure of the scraper assembly 5 ensures that the driving force is evenly distributed to the cleaning component 2, the rinsing nozzle 3, and the conveying component 4, avoiding torque loss caused by independent connection of multiple components.

[0077] In one embodiment, the cleaning component 2, the rinsing nozzle 3, and the conveying component 4 are all connected to the aforementioned connecting component 52.

[0078] In one embodiment, the cleaning device for the radial flow sedimentation tank further includes:

[0079] The sludge guiding component 6 is connected to the output end of the drive mechanism 1. The sludge guiding component 6 is located in the bottom sludge area of ​​the sedimentation tank 301. The sludge guiding component 6 has a sludge guiding channel and a sludge inlet. The sludge guiding channel is connected to the sludge discharge device 60. The sludge guiding channel is used to guide the sludge to the sludge discharge device 60. The sludge inlet is connected to the sludge guiding channel and the sedimentation tank 301. The opening direction of the sludge inlet is the same as the rotation direction of the sludge guiding component 6.

[0080] The sludge scraper 7 is located at the bottom of the sludge guiding component 6 and is used to loosen and collect sludge. Thus, the output of the drive mechanism 1 synchronously drives the sludge guiding component 6 and the sludge scraper 7 to move circumferentially along the sedimentation tank 301. During this process, the sludge scraper 7, located at the bottom of the sludge guiding component 6, directly acts on the bottom sludge area, loosening and collecting the sludge, facilitating sludge guidance by the sludge guiding component 6. Since the opening direction of the sludge inlet on the sludge guiding component 6 is the same as the rotation direction of the sludge guiding component 6, the sludge inlet always faces the sludge flow direction (or sludge accumulation surface) when the sludge guiding component 6 rotates, thereby reducing the resistance when sludge enters and preventing sludge splashing or escape caused by reverse or lateral openings. Simultaneously, when the sludge guiding component 6 rotates, the sludge moves outward under centrifugal force, and the sludge inlet designed in the same direction can fully utilize this centrifugal tendency, making it easier for the sludge to be drawn into the sludge inlet rather than being thrown away. If the opening direction is opposite to the rotation direction, the sludge may be pushed away, reducing the capture rate. Furthermore, since the sludge guide channel is connected to the sludge inlet, once the sludge is captured by the inlet, it can slide smoothly into the guide channel without secondary accumulation due to sudden changes in direction or structural interference. During rotation, the guide channel forms a stable sludge transport channel, ensuring the sludge continuously moves towards the sludge discharge device 60. More importantly, the unidirectional structure ensures that the sludge's movement direction within the guide channel is coordinated with the rotation direction of the guide component 6, preventing sludge retention or backflow due to countercurrent or turbulence, thereby reducing the risk of blockage and maintaining efficient transport, significantly improving sludge discharge efficiency.

[0081] See Figure 1 In one embodiment, both the sludge guiding component 6 and the sludge scraping component 7 are provided in two sets. The two sets of sludge guiding components 6 are symmetrically arranged along the vertical center line of the sedimentation tank body 30, and each set of sludge scraping components 7 is respectively located at the bottom of the corresponding set of sludge guiding components 6, so as to improve the sludge discharge efficiency.

[0082] Of course, in other embodiments, the mud guiding component 6 and the mud scraping component 7 may be provided with one or three or more sets.

[0083] In one embodiment, the cleaning device for the radial flow sedimentation tank further includes:

[0084] Rotary support component 8, the upper end of which is connected to the output end of drive mechanism 1, the end of scraper assembly 5 near the vertical center of sedimentation tank 301 and the end of mud guide component 6 near the vertical center of sedimentation tank 301 are both connected to rotary support component 8, so that scraper assembly 5 and mud guide component 6 are connected to the output end of drive mechanism 1 through rotary support component 8.

[0085] The vertical support component 9 is connected to the upper end of the slag scraper assembly 5 and the lower end of the vertical support component 9 is connected to the mud guide component 6, so as to increase the connection strength between the slag scraper assembly 5 and the rotating support component 8 and the structural stability of the mud guide component 6, thereby improving the overall rigidity, slag discharge efficiency and mud discharge efficiency of the device.

[0086] In one embodiment, there are multiple vertical support components 9, which are arranged at intervals along the length of the scraper assembly 5. Thus, by arranging multiple vertical support components 9 at intervals along the length of the scraper assembly 5, a distributed support structure is formed, which significantly enhances the overall rigidity and operational stability of the cleaning device, achieves uniform stress distribution, and effectively prevents deformation and vibration of the long-span scraper assembly 5 and the sludge guiding component 6 through multi-point support. This ensures continuous and stable contact between the cleaning component 2 and the inner wall of the effluent channel 40, while also ensuring continuous and stable operation of sludge and sludge discharge.

[0087] See Figure 1 In one embodiment, the cleaning device for the radial flow sedimentation tank further includes:

[0088] The first conveying pipe 10 is vertically arranged, and the lower end of the first conveying pipe 10 is connected to the outlet of the conveying component 4.

[0089] The second conveying pipe 20 is arranged horizontally and connects to the scraper assembly 5. The first end of the second conveying pipe 20 connects to the upper end of the first conveying pipe 10, and the second end connects to the flushing nozzle 3. The first conveying pipe 10 and the second conveying pipe 20 form an orthogonally arranged pipe structure, achieving a low-resistance transmission path for water flow from the top clear water zone of the sedimentation tank to the flushing nozzle 3. The first conveying pipe 10 performs fluid lifting, while the second conveying pipe 20 performs radial distribution, forming an optimized fluid dynamics layout. Secondly, the first conveying pipe 10 is arranged vertically, and the second conveying pipe 20 is integrated into the scraper assembly 5, resulting in a compact design where the pipe structure and connecting frame are spatially conformal. Thirdly, the segmented pipe structure formed by the first and second conveying pipes facilitates localized repair or replacement of blocked areas.

[0090] See Figure 1 and Figure 3In one embodiment, the drive mechanism 1 includes:

[0091] Motor 11, motor 11 is mounted on sedimentation tank body 30; and

[0092] The gear mechanism 12 has its input end connected to the output shaft of the motor 11, and its input end can rotate with the output shaft of the motor 11. The output end of the gear mechanism 12 is connected to the rotating support component 8. Thus, by using the motor 11 and gear mechanism 12 to form the drive mechanism 1, the rotational motion of the motor 11's output shaft is transmitted to the rotating support component 8 after speed change via the gear mechanism 12. This achieves smooth power output conversion and torque amplification, while the precision of gear transmission ensures the stability of the cleaning device's operation. Furthermore, the compact structure of the gear mechanism 12 optimizes the spatial layout of the cleaning device, thereby improving energy transfer efficiency while meeting the high torque drive requirements and enhancing the system's reliability under long-term operating conditions.

[0093] In one embodiment, the gear mechanism 12 includes:

[0094] The drive gear is sleeved on the output shaft of the motor 11 and can rotate with the output shaft of the motor 11; and

[0095] The driven gear meshes with the driving gear and is connected to the rotating support component 8. Thus, by employing a gear mechanism 12 with the driving and driven gears meshing, the power from the output shaft of the motor 11 is transmitted to the rotating support component 8 via gear meshing. This achieves smooth and reliable power transmission and torque amplification through the mechanical characteristics of gear meshing, while the precision of gear transmission ensures the synchronization and stability of the cleaning system's operation. Furthermore, the adjustable speed ratio of the gear meshing adapts to different operating conditions, thereby optimizing power transmission efficiency while enhancing the system's adaptability and durability.

[0096] Of course, in other embodiments, chain drive mechanism, belt drive mechanism, worm gear mechanism, etc. can be used to replace the gear mechanism 12.

[0097] Of course, in other embodiments, the drive mechanism 1 may also include only the motor 11, which directly drives the rotating support component 8 to rotate.
