Description

Technical Field

[0001] This application relates to the field of water treatment technology, and in particular to an integrated device for treating suspended solids and discharging sludge, 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.

[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 water inflow and a sludge collection hopper at the bottom for upward 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 fluid delivery branch pipe. The sludge transfer tank is located on one side of the radial flow sedimentation tank and connected to the 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

[0060] 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.

[0061] See Figures 1-6 This invention illustrates a preferred embodiment of a radial flow sedimentation system. The system includes a radial flow sedimentation tank and an integrated device for treating suspended solids and discharging sludge. The radial flow sedimentation tank comprises a sedimentation tank body 20 and a sludge discharge device 30. The sedimentation tank body 20 has a sedimentation trough 201. The integrated device for treating suspended solids and discharging sludge from the radial flow sedimentation tank includes:

[0062] A conveying component 1 is installed within the sedimentation tank 201 of the sedimentation tank body 20. The inlet of the conveying component 1 connects to the sedimentation tank 201, and the outlet of the conveying component 1 connects to the sludge discharge device 30. The conveying component 1 has a suspended solids treatment station and a sludge discharge station. The suspended solids treatment station is located in the middle suspended solids zone of the sedimentation tank 201. When the conveying component 1 is in the suspended solids treatment station, it is used to convey the suspended solids in the middle suspended solids zone of the sedimentation tank 201 to the sludge discharge device 30. The sludge discharge station is located in the bottom sludge zone of the sedimentation tank 201. When the conveying component 1 is in the sludge discharge station, it is used to convey the sludge in the bottom sludge zone of the sedimentation tank 201 to the sludge discharge device 30.

[0063] The driving mechanism 2 is provided on the sedimentation tank body 20. The first output end of the driving mechanism 2 is connected to the conveying component 1. The first output end of the driving mechanism 2 is used to drive the conveying component 1 to move, so that the conveying component 1 can switch between the suspended solid treatment station and the sludge discharge station.

[0064] For the suspended solid treatment and sludge discharge integrated device of the present utility model, the switching of the conveying component 1 between the suspended solid treatment station and the sludge discharge station is realized through the coordinated cooperation of the conveying component 1 and the driving mechanism 2, so that the same conveying component 1 has the dual functions of suspended solid treatment and sludge discharge. This not only improves the utilization rate of the conveying component 1, but also avoids the additional configuration of a dedicated conveying device to separately treat suspended solids and sludge, thereby facilitating cost reduction.

[0065] Specifically, in the case of treating suspended solids, start the driving mechanism 2, and use the driving mechanism 2 to drive the conveying component 1 to move from the sludge discharge station to the suspended solid treatment station, so that the conveying component 1 is positioned in the middle suspended solid area of the sedimentation tank 201. The conveying component 1 captures the difficult-to-settle suspended solids in the sedimentation tank 201 in real time, and conveys the difficult-to-settle suspended solids to the sludge discharge device 30 supporting the sedimentation tank body 20, and discharges them to the outside of the system through the sludge discharge device 30, effectively controlling the suspended solid concentration in the system, reducing the risk of suspended solid overflow, ensuring that the suspended solid index of the effluent meets the standard stably, and guaranteeing the effluent quality; while in the case of treating sludge, start the driving mechanism 2, and use the driving mechanism 2 to drive the conveying component 1 to move from the suspended solid treatment station to the sludge discharge station, so that the conveying component 1 is positioned in the bottom sludge area of the sedimentation tank 201. The conveying component 1 captures the sludge in the sedimentation tank 201 in real time, and conveys the sludge to the sludge discharge device 30 supporting the sedimentation tank body 20, and discharges them to the outside of the system through the sludge discharge device 30, which not only avoids the influence of sludge overflow on the effluent quality, but also prevents the sludge from interfering with the sedimentation of suspended solids, thereby guaranteeing the solid-liquid separation effect and the stable operation of the system.

[0066] In one embodiment, the conveying component 1 is a pump body. In this way, using the pump body as the conveying component 1 can efficiently and stably convey fluid media such as suspended solids and sludge, ensure continuous and reliable transmission efficiency, and at the same time can adjust the flow rate and pressure according to the working conditions, with strong adaptability and being convenient to integrate into the existing system.

[0067] Of course, in other embodiments, the conveying component 1 can also be a vacuum suction device, and the vacuum suction device can also realize the extraction of fluid media such as suspended solids and sludge through negative pressure.

[0068] In one embodiment, the second output end of the driving mechanism 2 is connected to the conveying component 1. The second output end of the driving mechanism 2 is used to drive the conveying component 1 to move circumferentially along the sedimentation tank 201, so that the conveying component 1 can dynamically capture suspended solids or sludge, and realize 360° all-round suspended solid treatment operation or 360° all-round sludge discharge operation.

[0069] See Figure 1 , in one embodiment, the integrated device for suspended matter treatment and sludge discharge further includes:

[0070] A flexible main pipe 3, the inlet of the flexible main pipe 3 is connected to the outlet of the conveying component 1;

[0071] A fluid conveying branch pipe 4, the fluid conveying branch pipe 4 is connected to the second output end of the driving mechanism 2, the inlet of the fluid conveying branch pipe 4 is connected to the outlet of the flexible main pipe 3, and the outlet of the fluid conveying branch pipe 4 is connected to the sludge discharge device 30. Thus, by connecting the fluid conveying branch pipe 4 to the second output end of the driving mechanism 2, the conveying component 1 is connected to the driving mechanism 2, ensuring that the conveying component 1 can rotate with the second output end of the driving mechanism 2. At the same time, by connecting the outlet of the conveying component 1 and the inlet of the fluid conveying branch pipe 4 through the flexible main pipe 3, the conveying component 1 is connected to the fluid conveying branch pipe 4 through the flexible main pipe 3, thereby realizing the connection between the conveying component 1 and the sludge discharge device 30 of the sedimentation tank body 20 and establishing a connection channel between the conveying component 1 and the sludge discharge device 30; in addition, the flexible characteristic of the flexible main pipe 3 ensures that the conveying component 1 can move freely with the first output end of the driving mechanism 2 without interference, enabling the conveying component 1 to flexibly switch between different working positions.

[0072] In one embodiment, the fluid conveying branch pipe 4 is a rigid pipe to ensure that the fluid conveying branch pipe 4 can be firmly connected to the second output end of the driving mechanism 2.

[0073] In one embodiment, a valve 41 is provided on the fluid conveying branch pipe 4, and the valve 41 is used to control the on-off of the fluid conveying branch pipe 4.

[0074] See Figures 5-6 , in one embodiment, the driving mechanism 2 includes:

[0075] A motor 21, the motor 21 is arranged on the sedimentation tank body 20;

[0076] A first transmission mechanism 22, the input end of the first transmission mechanism 22 is connected to the output shaft of the motor 21, the input end of the first transmission mechanism 22 can rotate with the output shaft of the motor 21, and the output end of the first transmission mechanism 22 has the second output end of the driving mechanism 2;

[0077] A second transmission mechanism 23, the input end of the second transmission mechanism 23 is connected to the output end of the first transmission mechanism 22, the input end of the second transmission mechanism 23 can rotate with the output end of the first transmission mechanism 22, and the output end of the second transmission mechanism 23 has the first output end of the driving mechanism 2; and

[0078] The clutch mechanism 24 controls the connection and disconnection between the output end of the first transmission mechanism 22 and the input end of the second transmission mechanism 23. Thus, when the conveying component 1 needs to be moved, the clutch mechanism 24 connects the output end of the first transmission mechanism 22 to the input end of the second transmission mechanism 23, allowing the rotational power output by the motor 21 to be transmitted to the second transmission mechanism 23 via the first transmission mechanism 22. The second transmission mechanism 23 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 22 drives the fluid conveying branch pipe 4 to rotate, which in turn drives the connected conveying component 1 to rotate, achieving linkage between the movement and rotation of the conveying component 1. When the conveying component 1 needs to be positioned at the suspended solids treatment station or the sludge discharge station, the clutch mechanism 24 disconnects the output end of the first transmission mechanism 22 from the input end of the second transmission mechanism 23, ensuring that the rotational power output by the motor 21 can only be transmitted to the first transmission mechanism 22 and not to the second transmission mechanism 23. The output of the first transmission mechanism 22 drives the conveying component 1 to rotate, thus separating the movement and rotation of the conveying component 1. This saves energy and reduces operating costs, while ensuring that the conveying component 1 is reliably positioned at the target work station. In summary, through the coordinated action of the motor 21, the first transmission mechanism 22, the second transmission mechanism 23, and the clutch mechanism 24, the synchronous operation of the movement and rotation of the conveying component 1 can be met, and the independent control of the rotation of the conveying component 1 under specific working conditions can be achieved through the clutch mechanism 24. Moreover, the same motor 21 is used for both the movement and rotation of the conveying component 1, which improves the utilization rate of the motor 21 and further reduces the overall operating cost. More importantly, regardless of whether the system is in the linkage mode of the movement and rotation of the conveying component 1 or the independent mode of only driving the rotation of the conveying component 1, the output shaft of the motor 21 always maintains a single rotation direction, ensuring that the rotation direction of the conveying component 1 is constant, effectively preventing water flow turbulence, and maintaining the stable operation and optimal separation efficiency of the radial flow sedimentation tank.

[0079] See Figures 5-6 In one embodiment, the first transmission mechanism 22 includes:

[0080] The drive gear 221 is sleeved on the output shaft of the motor 21 and can rotate with the output shaft of the motor 21; and

[0081] Driven gear 222 meshes with driving gear 221 and can rotate with driving gear 221. Driven gear 222 has a second output end of driving mechanism 2.

[0082] The second transmission mechanism 23 includes:

[0083] The driving worm gear 231 is connected to the driven gear 222, and the driving worm gear 231 can rotate with the driven gear 222;

[0084] Driven worm gear 232 and driving worm gear 231 are arranged radially apart along the sedimentation tank body 20;

[0085] The rising active worm 233 has its first end meshing with the active worm wheel 231, and the rising active worm 233 can rotate with the active worm wheel 231.

[0086] The driven worm 234 rises, and its first end meshes with the driven worm wheel 232.

[0087] The lowering drive worm 235 has its first end meshing with the drive worm wheel 231, and the lowering drive worm 235 can rotate with the drive worm wheel 231.

[0088] The driven worm 236 is lowered, and the first end of the driven worm 236 meshes with the driven worm wheel 232;

[0089] Lead screw 237, the upper end of which is connected to driven worm gear 232, and lead screw 237 can rotate with driven worm gear 232; and

[0090] Nut 238 is sleeved on lead screw 237. Nut 238 has a second output end of drive mechanism 2. Nut 238 is connected to conveying component 1. Nut 238 can move along lead screw 237 as lead screw 237 rotates, so as to drive conveying component 1 to move.

[0091] Clutch mechanism 24 includes:

[0092] The lifting clutch 241 is located between the second end of the lifting driving worm 233 and the second end of the lifting driven worm 234. The lifting clutch 241 is used to control the connection and disconnection of the second ends of the lifting driving worm 233 and the second ends of the lifting driven worm 234; and

[0093] The lowering clutch 242 is located between the second end of the lowering driving worm 235 and the second end of the lowering driven worm 236. The lowering clutch 242 is used to control the connection and disconnection of the second end of the lowering driving worm 235 and the second end of the lowering driven worm 236. Thus, the drive motor 21 drives the driven gear 222 to rotate via the drive gear 221, driving the conveying component 1 to perform 360° omnidirectional operations (including suspended solids suction and sludge suction). When lifting adjustment is required, the engagement of the worm gear transmission mechanism (rising drive worm 233 and rising driven worm 234, or falling drive worm 235 and falling driven worm 236) is controlled by the clutch (rising clutch 241 or falling clutch 242): when the rising clutch 241 is engaged, power is transmitted through the rising worm gear assembly (i.e., rising drive worm 233 and rising driven worm 234) to make the lead screw 237 rotate forward, driving the conveying component 1 to rise to the target position; when the falling clutch 242 is engaged, power is transmitted through the falling worm gear assembly (i.e., falling drive worm 235 and falling driven worm 236) to make the lead screw 237 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 21 is used to drive both rotation and lifting motion simultaneously, and bidirectional adjustment is achieved through a symmetrical worm gear transmission mechanism to keep the conveying component 1 rotating in the same direction at all times, 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 22 and the second transmission mechanism 23) ensures that the system achieves precise positioning in three-dimensional space while maintaining the solid-liquid separation efficiency of the radial flow sedimentation tank, significantly improving the system's operating efficiency.

[0094] It is understood that the drive mechanism 2 also includes a guide key or guide rail (not shown in the figure), which is used to constrain the nut 238, restricting the rotation of the nut 238 and ensuring that the nut 238 can only move linearly along the axis of the lead screw 237.

[0095] In one embodiment, both the lifting clutch 241 and the lowering clutch 242 are electromagnetic couplers. By using electromagnetic couplers as the lifting clutch 241 and the lowering clutch 242, 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 suspended solids treatment station and the sludge discharge 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.

[0096] Of course, in other embodiments, the lifting clutch 241 and the lowering clutch 242 can also be one of a mechanical clutch, a hydraulic clutch, a pneumatic clutch, or a magnetic powder clutch.

[0097] In one embodiment, there are multiple conveying components 1, which are arranged at intervals along the lateral side of the sedimentation tank 201.

[0098] There are multiple flexible main pipes 3, and the inlet of each flexible main pipe 3 is connected to the outlet of a corresponding conveying component 1;

[0099] The integrated suspended solids treatment and sludge removal device also includes:

[0100] The collecting pipe is placed horizontally in the sedimentation tank 201 and is connected to the outlet of multiple flexible main pipes 3 and the inlet of fluid conveying branch pipes 4.

[0101] The drive mechanism 2 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 3, and integrating multiple fluid channels using a converging pipe, 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 2, 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.

[0102] It can be understood that when there are multiple conveying components 1, the first output end of the drive mechanism 2 is multiple, specifically, the number of nuts 238 is multiple. In this case, there are multiple driven worm gears 232 and lead screws 237. Each driven worm gear 232 meshes with the rising driven worm 234 and the descending driven worm 236. Each lead screw 237 is connected to the corresponding driven worm gear 232. Each nut 238 is sleeved on the corresponding lead screw 237. Each nut 238 is connected to the corresponding conveying component 1.

[0103] Of course, in other embodiments, the drive mechanism 2 may include:

[0104] A first actuator, mounted on the sedimentation tank body 20, has a second output end of a drive mechanism 2. The output end of the first actuator is connected to a scraper assembly 8 to drive the scraper assembly 8 to rotate.

[0105] The second driver is located at the output end of the first driver. The second driver has a first output end of the drive mechanism 2. 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.

[0106] The aforementioned first driver includes a motor 21, or a combination of a motor 21 and any one of a gear mechanism, a chain drive mechanism, or a belt drive mechanism.

[0107] The aforementioned second driver may include linear drive mechanisms 2 such as electric push rods, cylinders, and hydraulic cylinders, or may include any linear drive mechanism 2 such as a motor 21, lead screw 237 and nut 238 pairs, and gear and rack mechanisms.

[0108] To facilitate the installation of the conveying component 1, in one embodiment, the integrated device for treating suspended solids and discharging sludge further includes:

[0109] See Figure 1 Rotary support component 5 is connected to the second output end of drive mechanism 2. Rotary support component 5 is sleeved on the upper part of sludge discharge device 30. Rotary support component 5 can rotate along sedimentation tank 201 with the second output end of drive mechanism 2. Fluid conveying branch pipe 4 is connected to rotary support component 5.

[0110] See Figure 1 In one embodiment, the integrated device for treating suspended solids and discharging sludge further includes:

[0111] The sludge guiding component 6 is connected to the rotating support component 5. The sludge guiding component 6 can rotate with the rotating support component 5 and move circumferentially along the sedimentation tank 201. The sludge guiding component 6 is located in the bottom sludge area of ​​the sedimentation tank 201. 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 30 and is used to guide the sludge to the sludge discharge device 30. The sludge inlet is connected to the sludge guiding channel and the sedimentation tank 201. The opening direction of the sludge inlet is the same as the rotation direction of the sludge guiding component 6.

[0112] 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 sludge guiding component 6 and the sludge scraper 7 are synchronously driven to move circumferentially along the sedimentation tank 201 via the second output end of the drive mechanism 2. 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 30. More importantly, the co-directional 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 clogging and maintaining efficient transport, significantly improving sludge discharge efficiency.

[0113] See Figure 4 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 20, and each set of sludge scraping components 7 is respectively located at the bottom of the corresponding set of sludge guiding components 6 to improve sludge discharge efficiency.

[0114] 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.

[0115] See Figures 1-2 In one embodiment, the integrated device for treating suspended solids and discharging sludge further includes:

[0116] Scraping component 8, the scraping component 8 is connected to the rotating support component 5, and the scraping component 8 can rotate with the rotating support component 5 and move circumferentially along the sedimentation tank 201. The scraping component 8 is used to gather the surface scum in the sedimentation tank 201 and push the surface scum to the slag discharging device 40 on the sedimentation tank body 20. In this way, by driving the mechanism 2 to drive the scraping component 8 to move circumferentially along the sedimentation tank 201, the scraping component 8 can push the surface scum in the sedimentation tank 201 to rotate and gather the surface scum at a preset slag discharging position (such as the slag discharging device 40 supporting the sedimentation tank body 20), which is convenient for timely removing the surface scum in the sedimentation tank 201, preventing the surface scum from overflowing into the water outlet channel along with the clear water in the sedimentation tank 201, and ensuring the water quality of the outlet water.

[0117] See Figures 1-2 , in one embodiment, the scraping component 8 includes:

[0118] The first scraping component 81, the first scraping component 81 is connected to the rotating support component 5, the first scraping component 81 is horizontally placed in the sedimentation tank 201, and the first scraping component 81 is used to push and gather the surface scum in the sedimentation tank 201;

[0119] The connecting component 82, the connecting component 82 is arranged on the top of the first scraping component 81; and

[0120] The second scraper component 83 is pivotally connected at its upper end to the connecting component 82, allowing it to swing up and down. The second scraper component 83 is located at the end near the vertical center of the first scraper component 81, away from the sedimentation tank. It scrapes the surface scum collected by the first scraper component 81 to the scum discharge device 40 located within the sedimentation tank 201. Thus, when the scraper assembly 8 rotates, the first scraper component 81 efficiently collects surface scum within the sedimentation tank 201. Simultaneously, as the first scraper component 81 rotates, the surface scum moves outward under centrifugal force. When the first scraper component 81 pushes the scum to the edge of the sedimentation tank 201, the swinging second scraper component 83 forms an inclined guide surface, precisely guiding the scum into the scum discharge device 40, preventing scum accumulation and blockage at corners. Therefore, the coordinated operation of the first scraper component 81 and the second scraper component 83 through the connecting component 82 ensures comprehensive scum removal. Among these features, the second scraper component 83 can swing up and down, allowing it to move freely with the liquid level. This ensures that the second scraper component 83 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 83 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 83. In addition, during the scraping process, the pivot structure can automatically adjust the fit between the second scraper component 83 and the side wall of the sedimentation tank 201, effectively reducing the escape of scum from the edge of the second scraper component 83 and improving the scum collection rate.

[0121] In one embodiment, the fluid delivery branch pipe 4 is connected to the aforementioned connecting component 82 to indirectly connect the delivery component 1 to the drive mechanism 2.

[0122] See Figure 1 In one embodiment, the integrated device for treating suspended solids and discharging sludge further includes:

[0123] An inclined support component 9 is provided, with its upper end connected to a rotating support component 5 and its lower end connected to a mud guide component 6, in order to increase the connection strength between the mud guide component 6 and the rotating support component 5 and prevent the mud guide component 6 from deforming and affecting the mud discharge efficiency.

[0124] The vertical support component 10 is connected to the upper end of the slag scraper assembly 8 and the lower end of the vertical support component 10 is connected to the mud guide component 6, so as to increase the connection strength between the slag scraper assembly 8 and the rotating support component 5 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.

[0125] See Figure 2In one embodiment, the integrated device for treating suspended solids and discharging sludge further includes:

[0126] A skimming component 50 is connected to a scraper assembly 8 and is located in the inlet channel of the radial flow sedimentation tank. The skimming component 50 is used to push and collect the floating scum in the inlet channel. By integrating the skimming component 50 onto the scraper assembly 8 and rotating it synchronously, the skimming component 50 continuously skims the floating scum from the water surface along the inlet channel to a preset retrieval position, where it is then manually cleaned. This achieves regular removal of floating scum, effectively inhibiting the accumulation and expansion of foam on the sludge surface and preventing odor generation. In addition, since the skimming component 50 is integrated onto the scraper assembly 8, the utilization rate of the scraper assembly 8 is improved, and the need for additional support structures to connect the skimming component 50 is avoided.

[0127] See Figure 1 In one embodiment, the slag discharge device 40 includes:

[0128] Slag discharge hopper 401 is connected to sedimentation tank body 20 and is located at the edge of sedimentation tank 201. The slag inlet of slag discharge hopper 401 is connected to sedimentation tank 201 to receive scum pushed by slag scraping assembly 8; and

[0129] The slag discharge pipe 402 has its inlet connected to the slag outlet of the slag discharge hopper 401, and its outlet connected to an external slag collection device, so that the floating slag can be discharged to the external slag collection device through the slag discharge pipe 402.

[0130] In summary, the working principle of the integrated suspended solids treatment and sludge removal device of this utility model is as follows:

[0131] Situation 1 (Daily Operation): The second output end of the drive mechanism 2 operates, driving the rotating support component 5 and the components connected to the rotating support component 5 (conveying component 1, sludge guiding component 6, sludge scraping component 7, slag scraping component 8, and slag skimming component 50) to rotate as a whole, achieving the following functions: the sludge guiding component 6 and the sludge scraping component 7 work together to scrape the bottom sludge, and use hydraulic and centrifugal force to press the sludge into the sludge discharge device 30; the slag scraping component 8 collects the surface scum of the sedimentation tank 201 and discharges it into the slag discharge device 40; the slag skimming component 50 collects the surface scum of the inlet channel and gathers it in one place.

[0132] Case 2 (Suspended solids treatment): The first output end of the drive mechanism 2 is started, the conveying component 1 moves to the middle of the sedimentation tank 201 to suck up the suspended solids (valve 41 is opened), and discharges them to the sludge discharge device 30 through the fluid conveying branch pipe 4, thereby discharging them outside the system. The remaining components remain in the working state of Case 1.

[0133] Situation 3 (Emergency Sludge Discharge): The first output end of the drive mechanism 2 drives the conveying component 1 to move to the bottom of the sedimentation tank to suck up the sludge (valve 41 is opened), and emergency sludge discharge is carried out through the fluid conveying branch pipe 4. Other components still maintain the operation mode of Situation 1.

[0134] This integrated suspended solids treatment and sludge discharge device integrates functions such as scum removal, sludge discharge, and emergency treatment through multi-condition adaptive switching, significantly improving system reliability and maintenance efficiency.

[0135] A preferred embodiment of this utility model provides a radial flow precipitation system, comprising:

[0136] Radial flow sedimentation tank; and

[0137] The above-mentioned integrated device for treating suspended solids and discharging sludge.

[0138] The radial flow sedimentation system of this utility model adopts the above-mentioned integrated device for suspended solids treatment and sludge discharge. It also achieves the switching between the suspended solids treatment station and the sludge discharge station through the coordinated cooperation of the conveying component 1 and the drive mechanism 2. This allows the same conveying component 1 to have both suspended solids treatment and sludge discharge functions, which not only improves the utilization rate of the conveying component 1, but also avoids the need to configure additional dedicated conveying devices to treat suspended solids and sludge separately, thereby helping to reduce costs.

[0139] See Figure 1 and Figure 4 In one embodiment, the radial flow precipitation system further includes:

[0140] The working bridge 60 has its first end connected to the sedimentation tank 20, and its second end extending to the vertical center of the sedimentation tank 20. The drive mechanism 2 is located on the second end of the working bridge 60, meaning the motor 21 is fixed to the second end of the working bridge 60. By setting the working bridge 60, the drive mechanism 2 is precisely positioned at the vertical center of the sedimentation tank 20, which optimizes the equipment space layout and provides a stable installation platform. At the same time, the rigid connection of the working bridge 60 ensures stable and accurate power transmission, maintaining the system's operational balance while also providing convenience for equipment installation and maintenance and overall structural vibration resistance. In addition, the working bridge 60 also functions as a walkway, providing maintenance personnel with a convenient passage for equipment inspection and tank condition patrol, achieving an integrated structural and functional design.
