Description

Technical Field

[0001] This application relates to the field of water treatment technology, and in particular to an integrated sludge removal and cleaning device and a radial flow sedimentation system. Background Technology

[0002] Radial flow sedimentation systems, as core solid-liquid separation equipment in water treatment processes, are widely used in municipal sewage, industrial wastewater, and water supply treatment. The system mainly consists of an inlet channel, a sedimentation tank, an effluent weir, and a rotary sludge scraper. The inlet channel surrounds the effluent weir and connects to the sedimentation tank, while the effluent weir is connected to the sedimentation tank via a top overflow outlet. During operation, sewage is evenly distributed into the sedimentation tank via the inlet channel. The sewage in the sedimentation tank undergoes solid-liquid separation through gravity settling during slow flow. The clarified supernatant flows through the top effluent weir into the effluent weir and is ultimately discharged from the system. The settled sludge is pushed by the rotary sludge scraper to a suction pipe and discharged through the first fluid delivery branch pipe.

[0003] Chinese utility model patent CN205412340U discloses an anti-clogging radial flow sewage sedimentation tank, which includes a radial flow sedimentation tank, a peripheral drive sludge scraper, a submersible sludge pump, and a sludge transfer tank. The radial flow sedimentation tank has a guide tube at the top for downward-facing water intake and a sludge collection hopper at the bottom for upward-facing sludge discharge. The peripheral drive sludge scraper is located in the middle of the radial flow sedimentation tank and rotates around the center of the tank. The sludge pump is suspended in the sludge collection hopper and discharges sludge from the bottom of the radial flow sedimentation tank upwards through a first fluid delivery branch pipe. The sludge transfer tank is located on one side of the radial flow sedimentation tank and connected to the first fluid delivery branch pipe. This anti-clogging radial flow sewage sedimentation tank changes the traditional bottom-embedded pipe sludge discharge method of the radial flow sedimentation system to a top sludge discharge method, effectively solving the problems of sludge caking and pipe blockage in traditional radial flow sedimentation systems. However, since the sludge pump is only used for sludge discharge, its utilization rate is low. Utility Model Content

[0065] 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.

[0066] The radial flow sedimentation system includes an inlet channel, a sedimentation tank 20, an outlet channel 30, a sludge suction pipe, and a first fluid delivery branch pipe 2. The inlet channel surrounds the outlet channel 30 and has water distribution holes on its bottom wall. The sedimentation tank 20 has a sedimentation trough 201 connected to the water distribution holes. The outlet channel 30 has an outlet trough 301 surrounding the top opening of the sedimentation trough 201 and connected to the top opening of the sedimentation trough 201. During operation, wastewater is evenly distributed to the sedimentation trough 201 through the water distribution holes of the inlet channel. The wastewater in the sedimentation trough 201 undergoes solid-liquid separation through gravity settling during slow flow. The clarified supernatant flows into the outlet channel 30 through the top outlet weir and is eventually discharged from the system. The settled sludge is pushed to the sludge suction pipe by a rotary scraper and discharged through the sludge discharge device 60.

[0067] When the clarified supernatant overflows into the effluent channel 30, algae and suspended solids tend to accumulate on the inner wall of the effluent channel 30 (located on the side near the top opening of the sedimentation tank 20). Current cleaning methods for maintaining the inner wall of the effluent channel 30 require manual scrubbing followed by high-pressure water jet rinsing after the machine is shut down, resulting in high workload for operators.

[0068] See Figures 1-6 This invention illustrates a preferred embodiment of an integrated sludge removal and cleaning device for use in a radial flow sedimentation system. The integrated sludge removal and cleaning device includes:

[0069] The conveying component 1 is located in the sedimentation tank 201 of the sedimentation tank 20. The inlet of the conveying component 1 is connected to the sedimentation tank 201. The conveying component 1 has a sludge discharge station and a cleaning station. The sludge discharge station is located in the bottom sludge area of ​​the sedimentation tank 201 so that the conveying component 1 can extract sludge. The cleaning station is located in the top clear water area of ​​the sedimentation tank 201 so that the conveying component 1 can extract clear water.

[0070] The inlet of the first fluid conveying branch pipe 2 is connected to the outlet of the conveying component 1. The outlet of the first fluid conveying branch pipe 2 is connected to the sludge discharge device 60 of the radial flow sedimentation system to realize the sludge being pumped to the sludge discharge device 60 and discharged to the outside of the system through the sludge discharge device 60.

[0071] The inlet of the second fluid delivery branch pipe 3 is connected to the outlet of the delivery component 1;

[0072] A flushing nozzle 4, the inlet of which is connected to the outlet of the second fluid delivery branch pipe 3, is used to flush the outlet tank 301 of the water outlet channel 30; and

[0073] The drive mechanism 5 is located on the sedimentation tank 20. The first output end of the drive mechanism 5 is connected to the conveying component 1. The drive mechanism 5 is used to drive the conveying component 1 to move between the sludge discharge station and the washing station.

[0074] This utility model's integrated sludge discharge and cleaning device controls the conveying component 1 to switch between sludge discharge and cleaning positions via a drive mechanism 5, achieving multi-purpose functionality with a single pump. Specifically, when the suction pipe is clogged, the conveying component 1 moves to the bottom sludge area of ​​the sedimentation tank 201, pumping the sludge out of the system via the first fluid conveying branch pipe 2. When cleaning is required, the conveying component 1 moves to the top clear water area to draw clean water, which is then conveyed via the second fluid conveying branch pipe 3 to the flushing nozzle 4 to rinse the inner wall of the outlet tank 301, effectively reducing algae and suspended solids adhesion. This integrated design significantly improves the utilization rate of the conveying component 1, while reducing manual maintenance requirements and enhancing system operating efficiency. In one embodiment, the outlet of the flushing nozzle 4 faces the inner wall of the outlet tank 301, which is located on the side near the top opening of the sedimentation tank 201, allowing direct rinsing of the inner wall of the outlet tank 301 and improving cleaning efficiency.

[0075] In one embodiment, the conveying component 1 is a pump body. Thus, by using a pump body as the conveying component 1, it is possible to efficiently and stably convey fluid media such as suspended solids, sludge, and clean water, 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.

[0076] Of course, in other embodiments, the conveying component 1 can also be a vacuum suction device, which extracts fluid media such as suspended solids, sludge, and clean water by negative pressure.

[0077] In one embodiment, the conveying component 1 also has a suspended solids treatment station, which is located in the suspended solids zone in the middle of the sedimentation tank 201. The conveying component 1 can move between the sludge discharge station, the suspended solids treatment station, and the cleaning station as the first output end of the drive mechanism 5 moves. Thus, when there is a large amount of suspended solids in the sedimentation tank 201, the drive mechanism 5 drives the conveying component 1 to move to the suspended solids treatment station, placing the conveying component 1 in the suspended solids zone in the middle of the sedimentation tank 201. The conveying component 1 then pumps the suspended solids out of the system through the first fluid conveying branch pipe 2, thereby removing suspended solids that are not easy to settle in the sedimentation tank 201, reducing the overflow of suspended solids, ensuring that the water quality meets the standards, and reducing environmental risks.

[0078] See Figure 1 In one embodiment, the integrated sludge removal and cleaning device further includes:

[0079] The first valve 6 is located on the first fluid delivery branch pipe 2 and is used to control the opening and closing of the first fluid delivery branch pipe 2.

[0080] The second valve 7 is provided on the second fluid conveying branch pipe 3, and the second valve 7 is used to control the on / off of the second fluid conveying branch pipe 3. By respectively arranging the first valve 6 and the second valve 7 on the first fluid conveying branch pipe 2 and the second fluid conveying branch pipe 3, independent and precise control of the sludge discharge and cleaning operations is achieved, avoiding mutual interference of fluid media, ensuring the reliability of system operation and operation flexibility, while optimizing the structural compactness and function integration degree of the device, and further enhancing the practicability and maintenance convenience of the equipment.

[0081] See Figure 1 , in one embodiment, the sludge discharge and cleaning integrated device further includes:

[0082] The flexible main pipe 8, the inlet of the flexible main pipe 8 is connected to the outlet of the conveying component 1, and the outlet of the flexible main pipe 8 is connected to the inlets of the first fluid conveying branch pipe 2 and the second fluid conveying branch pipe 3. Thus, by connecting the outlet of the conveying component 1, the inlet of the first fluid conveying branch pipe 2 and the inlet of the second fluid conveying branch pipe 3 through the flexible main pipe 8, the conveying component 1 is connected to the sludge discharge device 60 of the sedimentation tank 20 through the flexible main pipe 8, and the conveying component 1 is connected to the flushing nozzle 4 through the flexible main pipe 8, establishing both a connection channel between the conveying component 1 and the sludge discharge device 60 and a water supply path between the conveying component 1 and the flushing nozzle 4; in addition, the flexible characteristic of the flexible main pipe 8 ensures that the conveying component 1 can move freely with the first output end of the driving mechanism 5 without interference, enabling the conveying component 1 to flexibly switch between different workstations.

[0083] In one embodiment, the sludge discharge and cleaning integrated device further includes:

[0084] A rotating support component is connected to the second output end of the drive mechanism 5. This component rotates around the vertical centerline of the sedimentation tank 20 as the second output end of the drive mechanism 5 rotates. Both the first fluid delivery branch pipe 2 and the second fluid delivery branch pipe 3 are connected to the rotating support component. By setting up a rotating support component linked to the second output end of the drive mechanism 5, the first fluid delivery branch pipe 2, the second fluid delivery branch pipe 3, the delivery component 1, and the flushing nozzle 4 rotate synchronously around the vertical centerline of the sedimentation tank 20, achieving 360° omnidirectional sludge suction, 360° omnidirectional suspended solids suction, and 360° omnidirectional hydraulic flushing. This design not only ensures complete synchronization between the pipeline system and the movement of the delivery component 1, effectively preventing pipe entanglement, but also significantly improves space utilization efficiency. The synchronous rotation mechanism maintains dynamic balance during operation, enhancing system stability and operational reliability, achieving uniform and thorough tank cleaning, and significantly reducing equipment maintenance difficulty.

[0085] See Figures 5-6 In one embodiment, the drive mechanism 5 includes:

[0086] Motor 51 is installed on sedimentation tank 20;

[0087] The first transmission mechanism has an input end connected to the output shaft of the motor 51, and the input end of the first transmission mechanism can rotate with the output shaft of the motor 51. The output end of the first transmission mechanism has a second output end of the drive mechanism 5.

[0088] A second transmission mechanism has its input end connected to the output end of the first transmission mechanism. The input end of the second transmission mechanism can rotate with the output end of the first transmission mechanism. The output end of the second transmission mechanism has a first output end of the drive mechanism 5.

[0089] The clutch mechanism is used to control the connection and disconnection between the output end of the first transmission mechanism and the input end of the second transmission mechanism. Thus, when the conveying component 1 needs to be moved, the clutch mechanism is operated to connect the output end of the first transmission mechanism to the input end of the second transmission mechanism. This allows the rotational power output by the motor 51 to be transmitted to the second transmission mechanism via the first. The second transmission mechanism converts the rotational motion into linear motion to drive the conveying component 1, ensuring that the conveying component 1 can switch between different workstations. Simultaneously, the output end of the first transmission mechanism drives the rotating support component to rotate, which in turn drives the connected conveying component 1 and the flushing nozzle 4 to rotate synchronously, achieving linkage between the movement of the conveying component 1 and the rotation of the components (conveying component 1 and flushing nozzle 4). When the conveying component 1 needs to be positioned at any one of the three workstations—cleaning, suspended solids treatment, or sludge removal—the clutch mechanism is operated to disconnect the output end of the first transmission mechanism from the input end of the second transmission mechanism. This allows the rotational power output by the motor 51 to be transmitted only to the first transmission mechanism and not to the second. In this case, the output end of the first transmission mechanism drives the rotating support component to rotate, which in turn drives the connected conveying component 1 and the flushing nozzle. 4. Synchronous rotation separates the movement of the conveying component 1 from the rotation of the components (conveying component 1 and flushing nozzle 4), saving energy and reducing operating costs, while ensuring reliable positioning of the conveying component 1 at the target workstation. In summary, through the coordinated action of the motor 51, the first transmission mechanism, the second transmission mechanism, and the clutch mechanism, the synchronous operation requirements of the movement of the conveying component 1 and the rotation of the conveying component 1 and the flushing nozzle 4 can be met. Furthermore, the clutch mechanism enables independent control of the synchronous rotation of the conveying component 1 and the flushing nozzle 4 under specific working conditions. The same motor 51 is used for both the rotation of the step and the movement of the conveying component 1, which not only improves the utilization rate of the motor 51 but also further reduces the overall operating cost. More importantly, whether the system is in the linkage mode where the movement of the conveying component 1 and the synchronous rotation of the components (conveying component 1 and flushing nozzle 4) are synchronized, or in the independent mode where only the conveying component 1 and the flushing nozzle 4 are driven to rotate synchronously, the output shaft of the motor 51 always maintains a single rotation direction, ensuring that the rotation direction of the conveying component 1 and the flushing nozzle 4 is constant, effectively preventing water flow turbulence, and maintaining the stable operation and optimal separation efficiency of the radial flow sedimentation tank 20.

[0090] See Figures 5-6 In one embodiment, the first transmission mechanism includes:

[0091] The drive gear 52 is sleeved on the output shaft of the motor 51, and the drive gear 52 can rotate with the output shaft of the motor 51; and

[0092] Driven gear 53 meshes with driving gear 52 and can rotate with driving gear 52. Driven gear 53 has a second output end of driving mechanism 5.

[0093] The second transmission mechanism includes:

[0094] The driving worm gear 54 is connected to the driven gear 53 and can rotate with the driven gear 53.

[0095] Driven worm gear 55 and driving worm gear 54 are arranged radially apart along the sedimentation tank 20;

[0096] The rising active worm 56 has its first end meshing with the active worm wheel 54, and the rising active worm 56 can rotate with the active worm wheel 54.

[0097] The driven worm 57 rises, and the first end of the driven worm 57 meshes with the driven worm wheel 55;

[0098] The lowering drive worm 59 has its first end meshing with the drive worm wheel 54, and the lowering drive worm 59 can rotate with the drive worm wheel 54.

[0099] The driven worm 510 is lowered, and the first end of the driven worm 510 meshes with the driven worm wheel 55;

[0100] Lead screw 512, the upper end of which is connected to driven worm gear 55, and lead screw 512 can rotate with driven worm gear 55; and

[0101] Nut 513 is sleeved on lead screw 512. Nut 513 has a second output end of drive mechanism 5. Nut 513 is connected to conveying component 1. Nut 513 can move along lead screw 512 as lead screw 512 rotates, so as to drive conveying component 1 to move.

[0102] The clutch mechanism includes:

[0103] A lifting clutch 58 is located between the second end of the lifting driving worm 56 and the second end of the lifting driven worm 57. The lifting clutch 58 is used to control the connection and disconnection of the second ends of the lifting driving worm 56 and the second ends of the lifting driven worm 57.

[0104] The lowering clutch 511 is located between the second end of the lowering driving worm 59 and the second end of the lowering driven worm 510. The lowering clutch 511 is used to control the connection and disconnection of the second end of the lowering driving worm 59 and the second end of the lowering driven worm 510. Thus, the drive motor 51 drives the driven gear 53 to rotate via the drive gear 52, synchronously driving the conveying component 1 and the flushing nozzle 4 to perform 360° omnidirectional operations (including water flushing, suspended solids suction, and sludge suction). When lifting adjustment is required, the engagement of the worm gear transmission mechanism (rising drive worm 56 and rising driven worm 57, or falling drive worm 59 and falling driven worm 510) is controlled by the clutch (rising clutch 58 or falling clutch 511): when the rising clutch 58 is engaged, power is transmitted through the rising worm gear assembly (i.e., rising drive worm 56 and rising driven worm 57) to make the lead screw 512 rotate forward, driving the conveying component 1 to rise to the target position; when the falling clutch 511 is engaged, power is transmitted through the falling worm gear assembly (i.e., falling drive worm 59 and falling driven worm 510) to make the lead screw 512 rotate in reverse, realizing the falling of the conveying component 1. After reaching the target position, the clutch disengages to ensure positioning reliability. This solution has three major advantages: 1) A single motor 51 is used to drive both rotation and lifting motion simultaneously, and bidirectional adjustment is achieved through a symmetrical worm gear transmission mechanism to keep components such as the conveying component 1 and the flushing nozzle 4 rotating in the same direction, thus avoiding water flow disturbance; 2) Clutch control enables precise start and stop of lifting motion, ensuring positioning accuracy while reducing energy consumption; 3) The composite transmission mechanism (including the first transmission mechanism and the second transmission mechanism) ensures that the system maintains the solid-liquid separation efficiency of the radial flow sedimentation tank 20 while achieving precise positioning in three-dimensional space, significantly improving the system's operating efficiency.

[0105] It is understood that the drive mechanism 5 also includes a guide key or guide rail (not shown in the figure), which is used to constrain the nut 513, restricting the rotation of the nut 513 and ensuring that the nut 513 can only move linearly along the axis of the lead screw 512.

[0106] In one embodiment, both the lifting clutch 58 and the lowering clutch 511 are electromagnetic couplers. By using electromagnetic couplers as the lifting clutch 58 and the lowering clutch 511, rapid response and precise control of power transmission during the lifting and lowering process of the conveying component 1 are achieved. Electromagnetic couplers have the advantages of no mechanical wear, sensitive action, and remote control capability, making the switching of the conveying component 1 between the sludge discharge station, the suspended solids treatment station, and the cleaning station more efficient and reliable. At the same time, it simplifies the mechanical structure, improves the automation level and operational stability of the system, and reduces maintenance costs and the failure rate during its service life.

[0107] Of course, in other embodiments, the lifting clutch 58 and the lowering clutch 511 can also be one of a mechanical clutch, a hydraulic clutch, a pneumatic clutch, or a magnetic powder clutch.

[0108] Of course, in other embodiments, the drive mechanism 5 may include:

[0109] A first actuator, mounted on the sedimentation tank 20, has a second output end of a drive mechanism 5. The output end of the first actuator is connected to a rotating support component to drive the rotating support component to rotate.

[0110] The second driver is located at the output end of the first driver. The second driver has a first output end of the driving mechanism. The output end of the second driver is connected to the conveying component 1 to drive the conveying component 1 to move up and down.

[0111] The aforementioned first drive includes a motor, or a combination of a motor and any one of a gear mechanism, a chain drive mechanism, or a belt drive mechanism.

[0112] The aforementioned second driver may include linear drive mechanisms such as electric push rods, cylinders, and hydraulic cylinders, or it may include any linear drive mechanism such as a motor, lead screw and nut pair, or gear and rack mechanism.

[0113] In one embodiment, there are multiple conveying components 1, which are arranged at intervals along the lateral side of the sedimentation tank 201.

[0114] There are multiple flexible main tubes 8, and the inlet of each flexible main tube 8 is connected to the outlet of a corresponding conveying component 1.

[0115] The integrated sludge removal and cleaning device also includes:

[0116] The collecting pipe 10 is placed horizontally in the sedimentation tank 201. The collecting pipe 10 is connected to the outlet of multiple flexible main pipes 8, the inlet of the first fluid conveying branch pipe 2, and the inlet of the second fluid conveying branch pipe 3.

[0117] The drive mechanism 5 has multiple first output ends, each connected to a corresponding conveying component 1. Thus, by setting multiple horizontally spaced conveying components 1 and corresponding flexible main pipes 8, and integrating multiple fluid channels using a manifold 10, the sedimentation tank 201 achieves large-scale, high-efficiency parallel sludge suction and cleaning operations. The collaborative work of multiple conveying components 1 not only significantly improves processing capacity but also enables precise operation in local areas through independent control of each conveying component 1 by the drive mechanism 5, optimizing the system's adaptability to different operating conditions. This distributed layout combined with a centralized confluence design expands the coverage area while ensuring the integration of the pipeline system, effectively improving overall processing efficiency and operational reliability, and reducing the risk of single-point failures.

[0118] It can be understood that when there are multiple conveying components 1, the first output end of the drive mechanism 5 is multiple, specifically, the number of nuts 513 is multiple. In this case, the number of driven worm gears 55 and lead screws 512 is also multiple. Each driven worm gear 55 meshes with the rising driven worm 57 and the descending driven worm 510. Each lead screw 512 is connected to the corresponding driven worm gear 55. Each nut 513 is sleeved on the corresponding lead screw 512. Each nut 513 is connected to the corresponding conveying component 1.

[0119] In one embodiment, the rotating support component includes:

[0120] The first vertical support component 91 is connected to the second output end of the drive mechanism 5;

[0121] The first horizontal support component 92 is connected to the first vertical support component 91, the first fluid delivery branch pipe 2, and the second fluid delivery branch pipe 3.

[0122] A second horizontal support member 93 is connected to a first vertical support member 91 and is located below the first horizontal support member 92; and

[0123] The second vertical support component 94 is connected at its upper end to the first horizontal support component 92 and at its lower end to the second horizontal support component 93. The second vertical support component 94 is spaced apart from the first vertical support component 91. Thus, through the linkage between the first vertical support component 91 and the drive mechanism 5, and in conjunction with the vertically arranged first and second horizontal support components 92 and 93, and the spaced-apart second vertical support components 94, a stable three-dimensional support frame is constructed, ensuring that the first fluid delivery branch pipe 2 and the second fluid delivery branch pipe 3 maintain a uniform force distribution during rotation. This multi-directional support structure not only enhances the overall rigidity and operational stability of the rotating components but also effectively suppresses rotational vibration, preventing pipe displacement or deformation due to centrifugal force. Furthermore, the layered layout optimizes space utilization, ensuring the structural reliability and ease of maintenance of the device during long-term operation.

[0124] See Figures 1-2 In one embodiment, the integrated sludge removal and cleaning device further includes:

[0125] A cleaning brush 40 is installed inside the outlet trough 301 of the outlet channel 30. The cleaning brush 40 contacts the inner wall of the outlet trough 301. The cleaning brush 40 is connected to the second output end of the drive mechanism 5. The cleaning brush 40 can rotate around the vertical center line of the sedimentation tank 20 as the second output end of the drive mechanism 5 rotates, so as to mechanically scrub the inner wall of the outlet trough 301. Automatic rinsing of the inner wall of the outlet trough 301 is achieved by integrating the drive mechanism 5, the cleaning brush 40, the conveying component 1, and the rinsing nozzle 4. Specifically, the drive mechanism 5 is located at the vertical center of the sedimentation tank 20, and its second output end is connected to the cleaning brush 40 installed in the effluent trough 301. This allows the cleaning brush 40 to rotate around the vertical center of the sedimentation tank 20 and maintain contact and friction with the inner wall of the effluent trough 301, thus enabling thorough cleaning of the inner wall of the effluent trough 301. Simultaneously, the flushing nozzle 4 forms a directional flushing flow through its outlet facing the inner wall of the effluent trough 301. The supporting conveying component 1 uses the supernatant in the sedimentation tank 201 as a water source to transport the extracted clean water to the flushing nozzle 4, forming a circulating flush. The washing system, in conjunction with the cleaning brush 40, simultaneously performs mechanical brushing and hydraulic rinsing on the inner wall of the effluent trough 301, preventing algae and suspended solids from adhering to the inner wall of the effluent trough 301. In other words, this integrated sludge removal and cleaning device, through the synergistic effect of mechanical rotation brushing and hydraulic rinsing, can continuously remove algae and suspended solids adhering to the inner wall of the effluent channel 30 (i.e., the inner wall of the effluent trough 301) during the normal operation of the radial flow sedimentation system, effectively replacing the traditional manual cleaning method, significantly reducing the workload of operators and improving the continuous operating efficiency of the radial flow sedimentation system.

[0126] See Figures 1-4This invention illustrates a preferred embodiment of a radial flow precipitation system, comprising:

[0127] Sedimentation tank 20, which has a sedimentation tank 201;

[0128] The water outlet channel 30 has an outlet trough 301, which surrounds the top opening of the sedimentation tank 201 and communicates with the top opening of the sedimentation tank 201; and

[0129] The aforementioned integrated sludge removal and cleaning device.

[0130] This utility model's radial flow sedimentation system, employing the aforementioned integrated sludge discharge and cleaning device, also uses a drive mechanism 5 to control the conveying component 1 to switch between the sludge discharge and cleaning positions, achieving multi-purpose functionality with a single pump. Specifically, when the suction pipe is clogged, the conveying component 1 moves to the bottom sludge area of ​​the sedimentation tank 201, pumping the sludge out of the system via the first fluid conveying branch pipe 2. When cleaning is required, the conveying component 1 moves to the top clear water area to draw clean water, which is then conveyed via the second fluid conveying branch pipe 3 to the flushing nozzle 4 to rinse the inner wall of the outlet tank 301, effectively reducing the adhesion of algae and suspended solids. This integrated design significantly improves the utilization rate of the conveying component 1, while reducing the need for manual maintenance and enhancing system operating efficiency.

[0131] In one embodiment, the radial flow precipitation system further includes:

[0132] A working bridge 50 is radially arranged along the sedimentation tank 20. The first end of the working bridge 50 connects to the sedimentation tank 20, and the second end extends to the vertical center of the sedimentation tank 20. The drive mechanism 5 is located on the second end of the working bridge 50. By setting the radially extending working bridge 50, the drive mechanism 5 is precisely positioned at the vertical center of the sedimentation tank 20, optimizing the equipment space layout and providing a stable installation platform. Simultaneously, the rigid connection of the bridge ensures stable and precise power transmission, maintaining system balance while providing convenient equipment installation and maintenance, and enhancing the overall structural vibration resistance. Furthermore, the working bridge 50 also functions as a walkway, providing operators with a convenient passage for equipment inspection and tank condition monitoring, achieving an integrated structural and functional design.
