Description

Technical Field

[0001] This application relates to the field of wastewater treatment technology, specifically a system for enhancing the stable operation of secondary sedimentation tanks. Background Technology

[0002] Secondary sedimentation tanks are common treatment units in wastewater treatment systems, primarily used to further settle water after primary sedimentation, removing residual suspended solids, especially solid particles from flocculation treatment. The stable operation of the secondary sedimentation tank has a crucial impact on the overall performance of the wastewater treatment system.

[0003] However, traditional secondary sedimentation tank designs are often based solely on the principle of gravity settling, utilizing the density difference between sludge particles and water to allow the sludge particles to gradually settle to the bottom under gravity. But in actual operation, water flow disturbances can disrupt the settling equilibrium of the sludge particles, causing the sludge to remain suspended in the water and unable to be effectively separated. Furthermore, the significant differences in density, size, and shape among different sludge particles can lead to inconsistent settling velocities. This inconsistency not only weakens the overall settling effect but also reduces the stable operational efficiency of the secondary sedimentation tank.

[0004] Therefore, this application provides a system for enhancing the stable operation of a secondary sedimentation tank to solve the above-mentioned problems. Summary of the Invention

[0005] This application provides a system to enhance the stable operation of a secondary sedimentation tank, aiming to solve the problems mentioned in the background art, such as the traditional secondary sedimentation tank design relying solely on gravity settling, but the varying settling effects caused by water flow disturbance and differences in sludge particle characteristics, which reduce the stable operation efficiency of the secondary sedimentation tank.

[0006] To achieve the above objectives, this application provides the following technical solution: a system for enhancing the stable operation of a secondary sedimentation tank, comprising a tank body, an outlet trough fixedly disposed at the upper side of the tank body, an overflow weir fixedly installed in the tank body and fixedly connected to the inner side of the outlet trough, a baffle fixedly disposed in the tank body and fixedly connected to the inner side of the overflow weir, an operating platform fixedly disposed on the tank body, a central column rotatably connected to the center of the tank body and located below the operating platform, a sludge-removing structure disposed on the central column for removing sludge from the bottom of the tank body, a scraper fixedly connected to the outside of the central column and located inside the baffle for scraping off scum from the surface of the tank body, and a drive structure disposed on the operating platform for driving the central column to rotate;

[0007] The system also includes a dosing structure disposed on the scraper and connected to the drive structure for adding flocculant;

[0008] The dosing structure includes a drug storage tank located on one side of the bottom of the operating platform, a drug inlet pipe fixedly located at the bottom of the drug storage tank, an injection cylinder fixedly located on the scraper and connected to the drug inlet pipe, a piston that moves laterally within the injection cylinder, a push rod that passes laterally through the injection cylinder near the central column and is fixedly connected to the piston, a drug outlet pipe fixedly located on one side of the scraper and connected to the end of the injection cylinder away from the push rod, and a transmission structure located between the operating platform and the central column and connected to the driving structure for reciprocating movement of the push rod, wherein the push rod is slidably connected to the injection cylinder.

[0009] The push rod is equipped with an impact component near the transmission structure to impact the dispensing pipe. Through this dosing structure, the system can add flocculant to the tank while simultaneously pumping sludge. The flocculant helps sludge particles aggregate and settle more quickly, thus improving sludge settling efficiency. Rapid sludge settling helps reduce suspended solids concentration in the secondary sedimentation tank, maintaining water clarity and enhancing the stability and operational efficiency of the secondary sedimentation tank. Simultaneously, the impact component allows the dispensing pipe to be impacted simultaneously after the piston is pushed by the push rod to add flocculant from the injection cylinder into the tank, reducing flocculant residue and ensuring effective utilization of each added amount, further guaranteeing sludge settling efficiency.

[0010] Preferably, to facilitate the extraction of sludge from the bottom of the tank and maintain the stable operation of the secondary sedimentation tank, the sludge extraction structure includes a sludge pump fixedly installed inside the central column, sludge extraction pipes symmetrically fixed at both ends of the sludge pump and passing through both sides of the central column, and a sludge discharge pipe fixedly installed at the bottom of the tank and communicating with the central column and the bottom of the sludge pump. The sludge extraction pipes are fixedly connected to the central column. With the sludge pump fixedly installed inside the central column and the symmetrically arranged sludge extraction pipes, sludge can be efficiently extracted from the bottom of the tank. This design not only simplifies the sludge extraction process but also improves the efficiency of sludge treatment, helping to maintain the stable operation of the secondary sedimentation tank.

[0011] Preferably, in order to improve the sludge extraction effect, the sludge extraction pipe is fixedly connected to a branch pipe in a linear array on the side near the bottom of the tank; the design of the branch pipe in a linear array can more effectively cover the bottom of the tank, so as to ensure that the sludge at the bottom of the tank is extracted.

[0012] Preferably, to drive the central column, the drive structure includes a turntable rotatably connected to the operating platform, a connecting column fixedly connected to the turntable and fixedly connected to the top of the central column, and a motor fixedly mounted on the operating platform for driving the connecting column to rotate. The medicine storage tank is fixedly connected to one side of the connecting column. By driving the connecting column and the turntable to rotate through the motor, the central column and other structures on it will be driven to rotate. This drive method is simple, efficient, and easy to automate, thus improving the overall system operating efficiency.

[0013] Preferably, in order to transmit the power of the drive structure to the push rod, the transmission structure includes a drive gear fixedly sleeved on the connecting column and located between the operating platform and the central column; a transmission gear rotatably disposed on the top of the central column and meshing with one side of the drive gear; a connecting shaft fixedly connected to the transmission gear and rotatably connected to the top of the central column; a rotating wheel fixedly installed on the top of the connecting shaft and located below the operating platform; an eccentric rod fixedly connected to the rotating wheel; and connecting rods whose two ends are movably connected to the eccentric rod and the push rod respectively away from the piston. This design can indirectly transmit the power of the drive structure to the push rod and the impact assembly, realizing the automatic addition of flocculant and the impact of the discharge pipe, which not only improves the automation level of the system, but also ensures the stability and accuracy of the addition.

[0014] Preferably, in order to facilitate synchronous impact on the discharge pipe after dosing and reduce flocculant residue, the impact assembly includes a sleeve plate fixedly fitted to one end of the push rod near the connecting rod, a connecting frame fixedly disposed on one side of the sleeve plate and located on one side of the discharge pipe, and an impact plate fixedly installed on the connecting frame near the discharge pipe. This design not only improves the efficiency of flocculant use but also avoids waste due to residue.

[0015] Preferably, to prevent wear, a gasket is fixedly provided on the side of the impact plate near the drug delivery tube; the design of the gasket can effectively prevent wear during the impact process and extend the service life of the drug delivery tube and the impact plate.

[0016] Preferably, to ensure the effectiveness of flocculant addition, a horizontal tube is fixedly installed at the end of the dispensing pipe away from the injection cylinder, and the bottom end of the horizontal tube has spray holes distributed in a linear array; the combination design of the horizontal tube and the linear array of spray holes can make the flocculant sprayed more evenly in the pool, thus improving the flocculation effect.

[0017] Preferably, in order to prevent scum on the surface of the pool from affecting the use of the spray holes on the horizontal pipe, the height of the horizontal pipe is located at half the height of the scraper; this design can effectively prevent scum on the surface of the pool from entering the spray holes, thereby affecting the use of the spray holes and ensuring the addition of flocculant.

[0018] Preferably, to facilitate the removal of scum from the surface of the tank, a scum channel is fixedly installed on the tank body. The scum channel is located at the bottom of the scraper, and an opening for scum to enter is provided on the side of the scum channel near the scraper. This design allows the scraper to directly push the scum into the opening when it passes through the scum channel, and then discharge it through the scum channel. This not only improves the cleaning efficiency of the system, but also helps maintain the good operating condition of the secondary sedimentation tank and avoids the impact of scum on water quality and sludge treatment effect.

[0019] This system for enhancing the stable operation of the secondary sedimentation tank is designed with a dosing structure connected to the drive structure. This allows flocculants to be added to the tank simultaneously during sludge removal. The flocculants help sludge particles aggregate and settle more quickly, thereby improving sludge settling efficiency. Rapid sludge settling helps reduce the concentration of suspended solids in the secondary sedimentation tank, keeping the water clear and thus enhancing the stability and operational efficiency of the secondary sedimentation tank.

[0020] This system for enhancing the stable operation of the secondary sedimentation tank incorporates an impact component connected to a push rod. This component allows the flocculant in the injection cylinder to be added into the tank via the outlet pipe after the piston is pushed by the push rod. Simultaneously, the outlet pipe is impacted to reduce flocculant residue, ensuring that the amount of flocculant added each time is effectively utilized, and further enhancing the efficiency of sludge settling.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] This embodiment provides a system to enhance the stable operation of a secondary sedimentation tank, such as... Figures 1-8As shown, the system includes a pool body 1, an outlet trough 13 fixedly installed at the upper inner side of the pool body 1, an overflow weir 12 fixedly installed inside the pool body 1 and fixedly connected to the inner side of the outlet trough 13, a baffle 11 fixedly installed inside the pool body 1 and fixedly connected to the inner side of the overflow weir 12, an operating platform 2 fixedly installed on the pool body 1, a central column 3 rotatably connected to the center of the pool body 1 and located below the operating platform 2, a sludge-removing structure 4 installed on the central column 3 for removing sludge from the bottom of the pool body 1, a scraper 5 fixedly connected to the outside of the central column 3 and located inside the baffle 11 for scraping off scum from the surface of the pool body 1, and a drive structure 6 installed on the operating platform 2 for driving the central column 3 to rotate; the system also includes a flocculation mechanism installed on the scraper 5 and connected to the drive structure 6 for flocculation. The dosing structure 7 for adding coagulant includes a storage tank 71 located on one side of the bottom of the operating platform 2, a drug inlet pipe 72 fixedly located at the bottom of the storage tank 71, an injection cylinder 73 fixedly located on the scraper 5 and connected to the drug inlet pipe 72, a piston 74 that moves laterally within the injection cylinder 73, a push rod 75 that extends laterally through the injection cylinder 73 near the central column 3 and is fixedly connected to the piston 74, a drug outlet pipe 76 fixedly located on one side of the scraper 5 and connected to the end of the injection cylinder 73 away from the push rod 75, and a transmission structure 77 located between the operating platform 2 and the central column 3 and connected to the drive structure 6 for reciprocating movement of the push rod 75. The push rod 75 is slidably connected to the injection cylinder 73. An impact component 8 for impacting the drug outlet pipe 76 is provided at the end of the push rod 75 near the transmission structure 77.

[0039] Understandably, a horizontal tube 761 is fixedly installed at the end of the dispensing pipe 76 away from the syringe 73. The bottom end of the horizontal tube 761 has spray holes 7611 arranged in a linear array. The height of the horizontal tube 761 is located at half the height of the scraper 5. The combined design of the horizontal tube 761 and the linear array of spray holes 7611 allows the flocculant entering the dispensing pipe 76 to be sprayed more evenly into the tank 1, thereby improving the flocculation effect. At the same time, the design of the horizontal tube 761 being located at half the height of the scraper 5 can effectively prevent scum on the surface of the tank 1 from entering the spray holes 7611, thus affecting the use of the spray holes 7611 and ensuring the addition and use of flocculant.

[0040] It should be noted that a scum channel 14 is fixedly installed on the tank body 1. The scum channel 14 is located at the bottom of the scraper 5, and an opening 141 for scum to enter is provided on the side of the scum channel 14 near the scraper 5. This design allows the scraped scum to be directly pushed into the opening 141 and discharged through the scum channel 14 when the scraper 5 passes over the scum channel 14 as the central column 3 rotates. This not only improves the cleaning efficiency of the system, but also helps to maintain the good operating condition of the secondary sedimentation tank and avoids the impact of scum on water quality and sludge treatment effect.

[0041] In operation, when the system is started, the drive structure 6 drives the central column 3 to rotate. As the central column 3 rotates, it drives the scraper 5 and the sludge removal structure 4 to work synchronously. The scraper 5 scrapes off the scum on the surface of the pool 1 and pushes it into the opening 141 of the scum channel 14, allowing the scum to be discharged through the scum channel 14. At the same time, the sludge removal structure 4 removes the sludge from the bottom of the pool 1 to keep the pool 1 clean. However, during the rotation of the central column 3, the drive structure 77 transmits the power of the drive structure 6 to the push rod 75, causing the push rod 75 to reciprocate within the injection cylinder 73. As the push rod 75 reciprocates, it drives the piston 74 to move within the injection cylinder 73. When the piston moves away from the outlet pipe 76, the flocculant in the storage tank 71 is drawn into the injection cylinder 73 through the inlet pipe 72. When the piston 74 moves towards the outlet pipe 76, the piston 74 compresses the flocculant in the injection cylinder 73 and sprays it evenly into the tank 1 through the nozzles 7611 on the outlet pipe 76 and the horizontal pipe 761 to accelerate the sedimentation of sludge and maintain the stable operation of the secondary sedimentation tank. During the movement of the push rod 75, the impact component 8 will continuously impact the outlet pipe 76 to reduce the flocculant residue in the outlet pipe 76 and further make the flocculant evenly distributed. During the sedimentation of sewage, as the water level rises, the clear water on the surface of the tank 1 will flow into the outlet trough 13 through the overflow weir 12 to achieve continuous discharge of clear water.

[0042] Specifically, the drive structure 6 includes a turntable 61 rotatably connected to the operating platform 2, a connecting column 62 fixedly connected to the turntable 61 and fixedly connected to the top of the central column 3, and a motor 63 fixedly installed on the operating platform 2 for driving the connecting column 62 to rotate. The medicine storage tank 71 is fixedly connected to one side of the connecting column 62.

[0043] When the central column 3 needs to be driven to rotate, the motor 63 is started first. The motor 63 generates rotational power and transmits it to the turntable 61 through the output shaft. Then, the turntable 61 will synchronously drive the connecting column 62 connected to it to rotate. Immediately afterwards, the connecting column 62 will drive the central column 3 to rotate. Since the medicine storage tank 71 is connected to the connecting column 62 and the scraper 5 is connected to the central column 3, and the syringe 73 is connected to the scraper 5, when the connecting column 62 drives the central column 3 to rotate, the entire drug delivery structure 7 and the impact component 8 connected to the drug delivery structure 7 will also rotate synchronously.

[0044] Furthermore, the sludge removal structure 4 includes a sludge pump 41 fixedly installed inside the central column 3, sludge removal pipes 42 symmetrically fixedly installed at both ends of the sludge pump 41 and passing through both sides of the central column 3, and a sludge discharge pipe 43 fixedly installed at the bottom inside the pool body 1 and connected to the bottom of the central column 3 and the sludge pump 41. The sludge removal pipe 42 is fixedly connected to the central column 3.

[0045] In order to improve the sludge extraction effect, the sludge extraction pipe 42 is fixedly connected to a branch pipe 421 arranged in a linear array on one side of the bottom of the tank body 1. The design of the branch pipe 421 arranged in a linear array can more effectively cover the bottom of the tank body 1 to ensure that the sludge at the bottom of the tank body 1 is extracted.

[0046] When sludge needs to be removed, the drive structure 6 and the sludge pump 41 are started. At this time, the central column 3 will drive the branch pipe 421 to rotate inside the pool 1. At the same time, the sludge pump 41 will start working and generate negative pressure or suction. Under the suction of the sludge pump 41, the sludge at the bottom of the pool 1 is sucked into the sludge suction pipe 42 through the branch pipe 421, and then transported along the sludge suction pipe 42 to the sludge discharge pipe 43. Finally, it is discharged out of the pool 1 through the sludge discharge pipe 43, completing the sludge removal process.

[0047] Furthermore, the transmission structure 77 includes a drive gear 771 fixedly sleeved on the connecting column 62 and located between the operating platform 2 and the central column 3; a transmission gear 772 rotatably disposed at the top of the central column 3 and meshing with one side of the drive gear 771; a connecting shaft 773 fixedly connected to the transmission gear 772 and rotatably connected to the top of the central column 3; a rotating wheel 774 fixedly installed at the top of the connecting shaft 773 and located below the operating platform 2; an eccentric rod 775 fixedly connected to the rotating wheel 774; and a connecting rod 776 whose two ends are movably connected to the eccentric rod 775 and the push rod 75 respectively away from the piston 74.

[0048] When the starting motor 63 drives the connecting column 62 to rotate, the connecting column 62 will synchronously drive the drive gear 771 connected to it to rotate. Since the drive gear 771 meshes with the transmission gear 772, as the drive gear 771 rotates, the connecting shaft 773 on the transmission gear 772 will synchronously drive the rotating wheel 774 to rotate together. Since the rotating wheel 774 is connected to the eccentric rod 775, the eccentric rod 775 will perform eccentric rotational motion as the rotating wheel 774 rotates. Then, through the connection of the connecting rod 776, the connecting rod 776 will convert the eccentric rotational motion of the eccentric rod 775 into the reciprocating movement of the push rod 75. Thus, under the push of the connecting rod 776, the push rod 75 will synchronously reciprocate to push the piston 74 to move, thereby realizing the addition of flocculant.

[0049] Furthermore, the impact assembly 8 includes a sleeve plate 81 fixedly sleeved on one end of the push rod 75 near the connecting rod 776, a connecting frame 82 fixedly disposed on one side of the sleeve plate 81 and located on one side of the drug outlet tube 76, and an impact plate 83 fixedly installed on the connecting frame 82 near the drug outlet tube 76.

[0050] When push rod 75 pushes piston 74 to move closer to the end of the dispensing pipe 76, allowing the flocculant in syringe 73 to be added to tank 1 through dispensing pipe 76, sleeve plate 81 and connecting frame 82 will also move synchronously closer to the side of dispensing pipe 76. At this time, impact plate 83 will continuously approach dispensing pipe 76 under the drive of connecting frame 82. When push rod 75 pushes piston 74 to complete approaching the end of dispensing pipe 76, sleeve plate 81 will contact the outside of syringe 73, and impact plate 83 will collide with dispensing pipe 76. Under the impact of impact plate 83, a certain impact force will be generated, which can promote the discharge of residual flocculant in dispensing pipe 76. Conversely, when push rod 75 pushes piston 74 to move away from dispensing pipe 76, impact plate 83 will also move away from dispensing pipe 76 synchronously.

[0051] In addition, to prevent wear, a gasket 831 is fixedly installed on the side of the impact plate 83 near the drug delivery tube 76; the design of the gasket 831 can effectively prevent wear during the impact process and extend the service life of the drug delivery tube 76 and the impact plate 83.

[0052] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
