Description

Technical Field

[0001] The invention relates to the technical field of secondary sedimentation tanks, in particular to a secondary sedimentation tank capable of preventing a mud discharge pipe from being blocked and an anti-blocking method thereof. Background Art

[0002] As an important unit of the sewage treatment process, the secondary sedimentation tank mainly plays the role of mud and water separation. In actual operation, since the secondary sedimentation tank is mostly operated in the open air, some impurities in the sewage itself or larger debris accidentally dropped into the secondary sedimentation tank often cause the secondary sedimentation tank mud pipe to be blocked, which not only reduces the sewage treatment efficiency, but also greatly increases the maintenance cost and difficulty.

[0003] The design of traditional secondary sedimentation tanks often ignores the potential threat posed to the sludge discharge pipe by large particles or impurities that may be contained in the sludge. If these large particles or impurities, such as tree branches, workers' safety helmets, and larger and harder mud blocks, are not properly handled before entering the sludge discharge pipe, they can easily accumulate in the sludge discharge pipe, eventually leading to sludge discharge pipe blockage. Once the sludge discharge pipe is blocked, it not only requires a lot of manpower and financial resources to clear it, but also affects the normal operation of the sewage treatment plant.

[0004] To address these issues, existing technologies have developed a number of preventative measures for secondary sedimentation tank sludge pipe blockage, but these measures often suffer from inefficiencies, high energy consumption, and difficult maintenance. For example, some systems use simple filters to intercept large particles, but this approach often requires frequent and difficult cleaning of the filters. Failure to promptly remove debris trapped by the filters can lead to system failure. Furthermore, some systems attempt to flush blockages by increasing the pressure or flow rate in the sludge pipe, but this approach consumes significant energy and can damage the pipes, shortening their service life.

[0005] In view of this, the present invention proposes a new secondary sedimentation tank design that can prevent the clogging of the sludge discharge pipe, aiming to fundamentally solve the problem of clogging of the sludge discharge pipe through intelligent and efficient technical means.

[0014] Preferably, the adjustment assembly includes a rectangular plate, the top of the rectangular plate is fixedly connected to the bottom of the electric push rod, the bottom of the rectangular plate is provided with a rack, and the rack is slidably connected to the tube body.

[0015] Preferably, a plurality of gears are engaged with one side of the rack, the plurality of gears are evenly arranged, and the gears are fixedly connected to corresponding shafts.

[0016] Preferably, the maintenance assembly includes a cover plate, the inner side of the cover plate is rotatably connected to the platform, and a movable plate is provided at the bottom of the cover plate, and the movable plate is slidably connected to the platform.

[0018] A method for preventing clogging of a secondary sedimentation tank sludge discharge pipe comprises the following steps:

[0019] S1: The control component inside the box drives the telescopic rod to rotate downward and extend simultaneously, extending multiple diamond-shaped plates into the sludge hopper. The rotating component drives the pipe body to rotate. The slow rotation of the diamond-shaped plates can slowly stir the sludge inside the sludge hopper to prevent sludge agglomeration in the sludge hopper or impurities intercepted by the filter screen from causing sludge discharge from the sludge discharge pipe;

[0020] S2: Through multiple pressure sensors, the medium inside the sludge hopper can be identified when the diamond plate rotates. If the local operating pressure becomes larger, it indicates that harder impurities have appeared. At this time, the rotation angle of the adjustment plates on both sides is controlled by the electric telescopic rod to be in a horizontal state, which is used to isolate the connection between the pool body and the sludge hopper, so as to reduce the disturbance of the sludge layer inside the pool body during crushing. The impurities inside the sludge hopper are crushed by adjusting the deflection angle of the diamond plate. After the local excessive pressure disappears, the deflection angle of the diamond plate is adjusted back to a vertical state, and the rotation angle of the adjustment plates on both sides is controlled by the electric telescopic rod to be in a vertical state to ensure that the pool body and the sludge hopper are in a connected state; if the overall operating pressure is large, it indicates that there is more sludge in the sludge hopper at this time, and the sludge discharge operation can be appropriately increased in conjunction with the sludge discharge pipe; if the overall operating pressure is small, it indicates that there is less sludge in the sludge hopper at this time, and the sludge discharge operation can be appropriately reduced or not performed;

[0021] S3: The bottom component can be driven upward by the control component and the telescopic rod, and the maintenance component on the upper end of the platform can be used to perform daily maintenance and inspection of the device.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] Through the cooperation of the electric push rod and the adjustment component, the diamond plate can adjust the tilt angle according to the sludge state, realize the identification and crushing of sludge impurities, and effectively avoid blockage. Through the precise cooperation of the control component and the rotating component, the telescopic rod and the tube body can be adjusted at multiple angles and rotated. At the same time, the pressure sensor is used to monitor the operating pressure of the diamond plate in real time, intelligently identify the sludge state and impurity conditions, and accurately control the sludge discharge and crushing process. Under daily working conditions, the diamond plate slowly rotates along the vertical axis to stir the sludge to prevent agglomeration and clogging of the filter. When larger impurities are identified, the crushing function is activated to save power consumption and To extend the service life of the equipment, the maintenance component design enables the device to be stably operated in the shutdown state, which is convenient for maintenance and inspection. A filter is set between the sludge hopper and the sludge discharge pipe to effectively filter out larger impurities and prevent them from entering the sludge discharge pipe and causing blockage. The rotation of the diamond plate can not only break up the internal agglomerated sludge, but also scrape the impurities accumulated on the inside of the filter to prevent the filter from clogging. The electric telescopic rod drives the adjustment rack and the adjustment gear to rotate to realize the opening and closing control of the adjustment plate on the top of the sludge hopper. During crushing, it can block the connection between the secondary sedimentation tank and the sludge hopper on the bottom side of the secondary sedimentation tank to prevent the sludge layer of the secondary sedimentation tank from being disturbed during rotary crushing.

[0036] The following is combined with Figures 1-10 The specific embodiments of the present invention are described in further detail.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] Example 1:

[0039] Depend on Figures 1-10 The present invention proposes a secondary sedimentation tank that can prevent the clogging of the sludge discharge pipe: the present invention includes a tank body 1, and a platform 2 is provided on the top of the tank body 1. The platform 2 provides a safe and convenient working environment for operators and maintenance personnel. The platform 2 is usually equipped with guardrails and anti-slip measures to ensure the safety of personnel. A sludge hopper 5 is provided on one side of the bottom of the tank body 1. The sludge hopper 5 is located on one side of the inside of the tank body 1 and is a key area for sludge collection and deposition. The design of the sludge hopper 5 adopts a reasonable inclination angle and shape to ensure that the sludge can slide smoothly and be collected centrally. The outside of the sludge hopper 5 is connected to a sludge discharge pipe 22, which is used to transport the collected sludge to a subsequent treatment unit.

[0040] A track 27 is provided at the bottom of the platform 2, a slider 28 is provided at the bottom of the track 27, a box 3 is provided at the bottom of the slider 28, the inner side of the box 3 is fixedly connected to the middle of the pool body 1 to ensure the stability of the box 3, and when the platform 2 rotates along the central circumference of the platform 2, the track 27 will be driven to rotate. At this time, the position of the box 3 remains unchanged, and the slider 28 will slide in the track to ensure the stability of the box 3 when the workbench 2 rotates. The box 3 is made of high-strength, corrosion-resistant materials to ensure good stability and durability in harsh sewage environments. A control component is provided inside the box 3, and a telescopic rod 11 is provided at the bottom of the control component. The control component controls the telescopic rod 11 to rotate, thereby completing the adjustment of several states. A rotating component is provided at the bottom of the telescopic rod 11, and a tube 15 is provided at the bottom of the rotating component. The rotating component can drive the tube 15 to rotate. The tube 15 An electric push rod 16 is provided inside the body 15, and the top of the electric push rod 16 is connected to the top of the tube body 15. An adjustment component is provided at the bottom of the electric push rod 16, and a maintenance component is provided on the top of the platform 2. A plurality of shafts 21 are evenly arranged inside the adjustment component, and the plurality of shafts 21 are rotatably connected to the tube body 15. A diamond plate 20 is provided on the outside of the shaft 21, and the length of the diamond plate 20 becomes shorter from top to bottom. The inclination angle of the diamond plate 20 can be adjusted by cooperating with the electric push rod 16 and the adjustment component, and the adjustment can be made accordingly according to the specific situation. A plurality of pressure sensors are provided on the outer surface of the diamond plate 20, and the pressure sensors are evenly arranged on the surface of the diamond plate 20, so as to detect the pressure exerted on the diamond plate 20 when it moves, so as to facilitate the identification of the impurity state inside the sludge hopper 5, and then the corresponding control adjustment component is used to rotate the diamond plate 20 to complete the identification and crushing of sludge impurities.

[0041] The control component includes an adjusting motor 8, the top of which is fixedly connected to the inside of the box 3, a worm 9 is provided at the bottom of the adjusting motor 8, a worm wheel 10 is engaged with the outer side of the worm 9, the worm wheel 10 is rotationally connected to the box 3, and one side of the worm wheel 10 is fixedly connected to the top of the telescopic rod 11. When the external control system issues an instruction, the adjusting motor 8 starts and drives the worm 9 to rotate. The meshing transmission between the worm 9 and the worm wheel 10 causes the worm wheel 10 to start rotating, and the rotation of the worm wheel 10 drives the telescopic rod 11 to rotate.

[0042] The rotating assembly includes a shell 12, which is designed to be waterproof. The top of the shell 12 is rotatably connected to a connecting rod 13, the top of the connecting rod 13 is fixedly connected to the bottom of the telescopic rod 11, and the bottom of the connecting rod 13 is provided with a first motor 14, and the bottom of the first motor 14 is fixedly connected to the bottom of the shell 12. When the external control system issues an instruction, the first motor 14 starts and drives the connecting rod 13 to start rotating. The connecting rod 13 is connected to the top of the shell 12 through a rotating connection structure. Since the telescopic rod 11 is axially fixed in the design, the rotation of the first motor 14 will drive the connecting rod 13 to rotate under normal circumstances. However, in this device, since the connecting rod 13 is fixedly connected to the bottom of the telescopic rod 11, the rotational force generated by the first motor 14 will drive the first motor 14 itself to rotate. This torque will be transmitted to the first motor 14 and the shell 12, realizing the rotation of the shell 12 and the bottom tube body 15, and converting the rotational force into stirring and crushing force for the sludge in the sludge hopper 5.

[0043] The lower end of the telescopic rod 11 is provided with an electric telescopic rod 23, and the bottom of the electric telescopic rod 23 is provided with an adjusting rack 24. The bottom of the adjusting rack 24 is meshed with an adjusting gear 25, and the adjusting gear 25 is rotatably connected to the telescopic rod 11. An adjusting plate 26 is provided on the outside of the adjusting gear 25. The active extension and retraction of the electric telescopic rod 23 drives the adjusting rack 24 to move, and the adjusting rack 24 drives the adjusting gear 25 to rotate, thereby realizing the rotation of the adjusting plate 26. The width and length of the adjusting plate 26 match the top of the sludge hopper 5. The operator only needs to control the extension and retraction of the electric telescopic rod 23 to easily control the opening and closing degree of the sludge hopper. When the adjusting plate 26 is rotated to a horizontal state, the connection between the pool body 1 and the sludge hopper 5 can be cut off, and the rotation of the diamond plate 20 can be used to timely crush the sludge and impurities inside the sludge hopper 5, thereby avoiding disturbance of the sludge layer inside the pool body 1 during crushing and maintaining the stability of the internal liquid.

[0044] The adjustment component includes a rectangular plate 17, the top of the rectangular plate 17 is fixedly connected to the bottom of the electric push rod 16, and the electric push rod 16 serves as a power source, which drives the rectangular plate 17 up and down through telescopic movement. A rack 18 is provided at the bottom of the rectangular plate 17, and the rack 18 is slidably connected to the tube body 15. A plurality of gears 19 are meshed on one side of the rack 18. The plurality of gears 19 are evenly arranged, and the gears 19 are fixedly connected to the corresponding shaft 21. When the rack 18 moves up and down, it drives the gear 19 meshed with it to rotate, and then drives the diamond plate 20 to rotate in a circle through the shaft 21. Multiple pressure sensors are used to monitor the changes in the operating pressure during the rotation of the diamond plate 20 in real time, so as to judge the sludge hopper. 5. The state of the internal sludge and the situation of impurities. The number of pressure sensors can be adjusted according to the corresponding accuracy requirements. The higher the accuracy requirement, the more uniformly distributed the pressure sensors. The pressure change of the surface is analyzed by relying on the pressure recognition of a single point. The area of the local pressure abnormality of the diamond plate 20 is inferred through the logical operation of the external control system, thereby identifying the size of the impurities. Under normal working conditions, the diamond plate slowly rotates along the vertical axis to stir the sludge. When one or some pressure sensors detect that the local operating pressure becomes higher, it indicates that there are larger and harder impurities in the area. At this time, the adjustment plate 26 is adjusted to a horizontal state to isolate the connection between the tank body 1 and the sludge hopper 5. The diamond plate 20 is controlled to deflect during the rotation process, thereby achieving effective crushing of the impurities inside the sludge hopper 5. As the crushing action proceeds, when the pressure sensor detects that the overall operating pressure is low, it indicates that the crushing of larger and harder impurities is completed at this time, and then the diamond plate 20 is adjusted to a vertical state, and the stirring is continued slowly while the internal situation is identified. As long as the equipment identifies that there are harder impurities or impurities exceeding a certain size, the crushing function will be started, otherwise it will not be started. The advantage of doing this is that it can save power consumption of the equipment and can effectively guarantee the service life of the machine. A filter 29 is provided at the interface between the sludge hopper 5 and the mud discharge pipe 22, which can continuously crush larger impurities. Filtration. Under normal working conditions, the diamond plate 20 is in a vertical state. At this time, slow rotation can stir the sludge inside the sludge hopper 5 to prevent sludge clumping and blockage. At the same time, the diamond plate 20 can also scrape and break the impurities accumulated on the inside of the filter screen 29 in time to prevent blockage on the inside of the filter screen 29. When all or most of the pressure sensors detect that the overall operating pressure is large, it indicates that there is more sludge inside the sludge hopper 5. At this time, the sludge discharge operation can be appropriately increased, and the sludge can be discharged from the sludge hopper 5 through the sludge discharge pipe 22. When all pressure sensors detect that the overall operating pressure is small, it indicates that there is less sludge inside the sludge hopper 5. The sludge discharge operation can be appropriately reduced or not performed.

[0045] The maintenance assembly includes a cover plate 6, the inner side of the cover plate 6 is rotatably connected to the platform 2, and a movable plate 7 is provided at the bottom of the cover plate 6, which is slidably connected to the platform 2. When the device needs to be repaired, the telescopic rod 11 is controlled to rotate upward and the cover plate 6 is flipped upward. After the device extends out of the platform 2, the movable plate 7 is pulled inward to undertake the bottom of the device, so as to achieve the following Figure 5 In the state shown, the control component can be shut down to reduce energy consumption, and the stability of the device can be ensured under the support of the movable plate 7, making device maintenance more convenient.

[0046] An electric telescopic rod 23 is provided inside the telescopic rod 11, and an adjusting rack 24 is provided at the bottom of the electric telescopic rod 23. An adjusting gear 25 is meshed at the bottom of the adjusting rack 24, and the adjusting gear 25 is rotatably connected to the telescopic rod 11. An adjusting plate 26 is provided on the outside of the adjusting gear 25. The active extension and retraction of the electric telescopic rod 23 drives the adjusting rack 24 to move, and the adjusting rack 24 drives the adjusting gear 25 to rotate, thereby realizing the rotation of the adjusting plate 26. The width and length of the adjusting plate 26 match the top of the sludge hopper 5. The operator only needs to control the extension and retraction of the electric telescopic rod 23 to easily control the opening and closing degree of the sludge hopper. When the adjusting plate 26 is rotated to a horizontal state, the top of the sludge hopper 5 can be closed, and the sludge inside the sludge hopper 5 can be crushed by cooperating with the rotation of the diamond plate 20 to prevent turbulence caused by the rotation of the diamond plate 20 from entering the interior of the pool body 1, thereby maintaining the stability of the internal liquid.

[0047] Correspondingly, a scraper is provided at the bottom of the platform 2. The scraper is a prior art and will not be described in detail here. An angle sensor is provided at the bottom of the platform 2. The angle sensor can identify the axial rotation angle of the scraper. Figure 11 In the state shown, the scraper blade can be seen from above. When installing the angle sensor, the left side of the scraper blade at point C (centered on the central axis of the secondary sedimentation tank) is set as the starting position, that is, the 0 degree position, and the circumferential angle occupied by the scraper blade is set as X. o When the scraper blade rotates counterclockwise, the left side plate (with the central axis of the secondary sedimentation tank as the center) rotates X degrees, and the position of the left side plate of the scraper blade at point D (with the central axis of the secondary sedimentation tank as the center) also moves in a circular motion to the lifting position. At this time, the left side plate of the scraper blade (with the central axis of the secondary sedimentation tank as the center) begins to overlap with one side of the sludge hopper 5. Before the overlap, the diamond plate 20 and other components can be controlled to be lifted to prevent these components from interfering with the scraper blade. When the left side plate of the scraper blade (with the central axis of the secondary sedimentation tank as the center) continues to rotate (180-X+X o) degrees, the diamond plate 20 and other components continue to extend into the sludge hopper 5 to identify and crush the sludge, and then the left side plate of the scraper at point C (centered on the central axis of the secondary sedimentation tank) continues to rotate X degrees and begins to overlap with one side of the sludge hopper 5 again, and continues to control the diamond plate 20 and other components to lift up, repeating the above operations to complete the crushing of the sludge inside the sludge hopper 5 without hindering the normal operation of the scraper.

[0048] Example 2:

[0049] A method for preventing clogging of a secondary sedimentation tank sludge discharge pipe comprises the following steps:

[0050] S1: The control assembly inside the box 3 drives the telescopic rod 11 to rotate downward and extend simultaneously, and the multiple diamond plates 20 are inserted into the sludge hopper 5. The rotating assembly drives the tube body 15 to rotate. The slow rotation of the diamond plates 20 can slowly stir the sludge inside the sludge hopper 5 to prevent the sludge in the sludge hopper from agglomerating or impurities intercepted by the filter screen 29 from causing the sludge discharge pipe to be blocked;

[0051] S2: Multiple pressure sensors can be used to identify the medium inside the sludge hopper 5 when the diamond plate 20 rotates. If the local operating pressure becomes larger, it indicates that harder impurities have appeared. At this time, the electric telescopic rod 23 is used to control the rotation angle of the adjusting plates 26 on both sides to make them horizontal, which is used to isolate the connection between the pool body 1 and the sludge hopper 5, so as to reduce the disturbance of the sludge layer inside the pool body 1 during crushing. By adjusting the deflection angle of the diamond plate 20, the impurities inside the sludge hopper 5 are crushed. After the local excessive pressure disappears, the deflection angle of the diamond plate 20 is adjusted back to the vertical state, and the electric telescopic rod 23 is used to control the rotation angle of the adjusting plates 26 on both sides to make them vertical, so as to ensure that the pool body 1 and the sludge hopper 5 are in a connected state; if the overall operating pressure is large, it indicates that there is more sludge in the sludge hopper 5 at this time, and the sludge discharge operation can be appropriately increased in conjunction with the sludge discharge pipe 22; if the overall operating pressure is small, it indicates that there is less sludge in the sludge hopper 5 at this time, and the sludge discharge operation can be appropriately reduced or not performed;

[0052] S3: The bottom component can be driven to move upward by the control component and the telescopic rod 11, and the maintenance component at the upper end of the platform 2 can be used to perform daily maintenance and inspection on the device.

[0053] Specifically, by providing multiple pressure sensors on the outer surface of the diamond plate 20, the rotation pressure is monitored in real time, the impurity state inside the sludge hopper 5 is accurately identified, and when larger and harder impurities are identified, the diamond plate 20 is controlled to be deflected and crushed, thereby improving the crushing efficiency of sludge and impurities, saving electricity consumption, and extending the life of the equipment. Under normal conditions, the diamond plate 20 slowly rotates to stir the sludge to prevent the sludge in the sludge hopper 5 from agglomerating or impurities intercepted by the filter screen 29 from causing poor sludge discharge from the sludge pipe. The maintenance component includes a cover plate 6 and a movable plate 7, which are convenient for supporting and stabilizing the device during maintenance, reducing energy consumption, improving maintenance convenience, improving sludge treatment efficiency and quality, reducing the risk of blockage, extending the service life of the equipment, and saving energy consumption. When the adjustment plate 26 rotates to a horizontal state, the top of the sludge hopper 5 can be closed, and the sludge inside the sludge hopper 5 can be crushed in conjunction with the rotation of the diamond plate 20, preventing turbulence caused by the rotation of the diamond plate 20 from entering the interior of the pool body 1, and maintaining the stability of the internal liquid.

10. A method for preventing clogging of a sludge discharge pipe of a secondary sedimentation tank, the method comprising the following steps: S1: The control assembly inside the box (3) drives the telescopic rod (11) to rotate downward and extend at the same time, and the plurality of diamond plates (20) are extended into the sludge hopper (5). The rotating assembly drives the pipe body (15) to rotate. The slow rotation of the diamond plates (20) can slowly stir the sludge inside the sludge hopper (5) to prevent the sludge in the sludge hopper from agglomerating or the impurities intercepted by the filter screen (29) from causing the sludge discharge pipe to be blocked; S2: The medium inside the sludge hopper (5) can be identified by multiple pressure sensors when the diamond plate (20) rotates. If the local operating pressure increases, it indicates that hard impurities have appeared. At this time, the rotation angle of the adjustment plates (26) on both sides is controlled by the electric telescopic rod (23) to make them in a horizontal state, which is used to cut off the connection between the tank body (1) and the sludge hopper (5) to reduce the disturbance of the sludge layer inside the tank body (1) during crushing. By adjusting the deflection angle of the diamond plate (20), the impurities inside the sludge hopper (5) are crushed. After the local excessive pressure disappears, the deflection angle of the diamond plate (20) is adjusted back to the vertical state, and the rotation angle of the adjustment plates (26) on both sides is controlled by the electric telescopic rod (23) to make them in the vertical state, so as to ensure that the tank body (1) and the sludge hopper (5) are in a connected state; if the overall operating pressure is large, it indicates that there is a lot of sludge inside the sludge hopper (5) at this time, and the sludge discharge operation can be appropriately increased in conjunction with the sludge discharge pipe (22); if the overall operating pressure is small, it indicates that there is a little sludge inside the sludge hopper (5) at this time, and the sludge discharge operation can be appropriately reduced or not performed; S3: The bottom component can be driven to move upwards by the control component and the telescopic rod (11), and the maintenance component at the upper end of the platform (2) can be used to perform daily maintenance and repairs on the device.
