Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and specifically to a system for enhancing the stable operation of a secondary sedimentation tank. Background Art

[0002] The secondary sedimentation tank is a common treatment unit in the sewage treatment system. It is mainly used to further settle the water after the primary sedimentation tank treatment and remove the remaining suspended matter in the water, especially the solid particles after flocculation treatment. The stable operation of the secondary sedimentation tank has a vital impact on the overall performance of the sewage treatment system.

[0003] However, the traditional secondary sedimentation tank design is often based only on the principle of gravity sedimentation, that is, using the density difference between sludge particles and water to make the sludge particles gradually settle to the bottom under the action of gravity. However, in actual operation, the sedimentation balance of sludge particles may be destroyed due to water flow disturbance, causing the sludge to be suspended in the water and unable to be effectively separated. Secondly, the density, size and shape of different sludge particles vary greatly, which may lead to inconsistent sedimentation speed. This inconsistency not only weakens the overall sedimentation effect, but also reduces the stable operation efficiency of the secondary sedimentation tank.

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

[0005] The present application provides a system for enhancing the stable operation of a secondary sedimentation tank, aiming to solve the problem that the traditional secondary sedimentation tank design proposed in the background technology relies solely on gravity sedimentation, but the water flow disturbance and differences in sludge particle characteristics lead to different sedimentation effects, thereby reducing the stable operation efficiency of the secondary sedimentation tank.

At the same time, through the provided impact component, after the piston is pushed by the push rod to add the flocculant in the injection cylinder from the drug outlet pipe into the tank body, the drug outlet pipe can also be impacted synchronously to reduce the residue of the flocculant, ensure that the amount of medicine added each time is effectively utilized, and further ensure the efficiency of sludge sedimentation.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0038] This embodiment provides a system for enhancing the stable operation of the secondary sedimentation tank, such as Figure 1-Figure 8As shown, the system includes a tank body 1, a water outlet trough 13 fixedly arranged at an upper position inside the tank body 1, an overflow weir 12 fixedly installed in the tank body 1 and fixedly connected to the inner side of the water outlet trough 13, a baffle 11 fixedly arranged in the tank body 1 and fixedly connected to the inner side of the overflow weir 12, an operating platform 2 fixedly arranged on the tank body 1, a central column 3 rotatably connected to the center position inside the tank body 1 and located below the operating platform 2, a sludge extraction structure 4 arranged on the central column 3 for extracting sludge from the bottom end of the tank body 1, a scraper 5 fixedly connected to the outer side of the central column 3 and located inside the baffle 11 for scraping scum on the surface of the tank body 1, and a driving structure 6 arranged on the operating platform 2 for driving the central column 3 to rotate; the system also includes a scraper 5 and connected to the driving structure 6 for flocculants. A dosing structure 7 for adding a coagulant; the dosing structure 7 includes a medicine storage barrel 71 arranged on one side of the bottom end of the operating platform 2, a medicine inlet pipe 72 fixedly arranged at the bottom end of the medicine storage barrel 71, an injection barrel 73 fixedly arranged on the scraper 5 and connected to the medicine inlet pipe 72, a piston 74 that moves laterally in the injection barrel 73, a push rod 75 that laterally penetrates the injection barrel 73 on one side close to the center column 3 and is fixedly connected to the piston 74, a medicine outlet pipe 76 that is fixedly arranged on one side of the scraper 5 and connected to one end of the injection barrel 73 away from the push rod 75, and a transmission structure 77 arranged between the operating platform 2 and the center column 3 and connected to the driving structure 6 for reciprocating the push rod 75, and the push rod 75 is slidably connected to the injection barrel 73; an impact component 8 for impacting the medicine outlet pipe 76 is provided at one end of the push rod 75 close to the transmission structure 77.

[0039] It can be understood that a transverse tube 761 is fixedly installed at one end of the medicine outlet pipe 76 away from the injection cylinder 73, and spray holes 7611 distributed in a linear array are opened at the bottom end of the transverse tube 761. The height of the transverse tube 761 is located at half the height of the scraper 5; the combined design of the transverse tube 761 and the spray holes 7611 distributed in a linear array can make the flocculant entering the medicine outlet pipe 76 be sprayed more evenly in the pool body 1 to improve the flocculation effect. At the same time, the design of the height of the transverse tube 761 being located at half the height of the scraper 5 can effectively prevent the scum on the surface of the pool body 1 from entering the spray holes 7611, thereby affecting the use of the spray holes 7611, thereby ensuring the addition and use of the flocculant.

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

[0041] During use, when the system is started, the driving structure 6 will drive the central column 3 to rotate. As the central column 3 rotates, it will drive the scraper 5 and the mud pumping structure 4 to work synchronously, wherein the scraper 5 will scrape off the scum on the water surface of the pool body 1 and push it into the opening 141 of the scum channel 14, so that the scum is then discharged through the scum channel 14. At the same time, the mud pumping structure 4 will extract the sludge at the bottom of the pool body 1 to keep the pool body 1 clean. However, during the rotation of the central column 3, through the transmission action of the transmission structure 77, it will transmit the power of the driving structure 6 to the push rod 75, so that the push rod 75 makes a reciprocating motion in the injection cylinder 73. As the push rod 75 reciprocates, it will drive the piston 74 to move in the injection cylinder 73. When the piston 74 When it moves toward the end away from the medicine outlet pipe 76, the flocculant in the medicine storage barrel 71 is sucked into the injection cylinder 73 through the medicine inlet pipe 72. When the piston 74 moves toward the end close to the medicine outlet pipe 76, the piston 74 will compress the flocculant in the injection cylinder 73 and evenly spray it into the tank body 1 through the spray holes 7611 on the medicine outlet pipe 76 and the cross pipe 761, so as to accelerate the sedimentation of the 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 medicine outlet pipe 76 to reduce the residual flocculant in the medicine outlet pipe 76 and further evenly distribute the flocculant. During the sedimentation of sewage, as the water level rises, the clean water on the surface of the tank body 1 will flow into the water outlet trough 13 through the overflow weir 12 to achieve continuous discharge of clean water.

[0042] Specifically, the driving 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 arranged on the operating platform 2 for driving the connecting column 62 to rotate, and the medicine storage barrel 71 is fixedly connected to one side of the connecting column 62;

[0043] When it is necessary to drive the center column 3 to rotate, start the motor 63 first. The motor 63 will generate rotational power and transmit 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, and then the connecting column 62 will drive the center column 3 to rotate. Since the medicine storage barrel 71 is connected to the connecting column 62, and the scraper 5 is connected to the center column 3, and the injection cylinder 73 is connected to the scraper 5, when the connecting column 62 drives the center column 3 to rotate, the entire dosing structure 7 and the impact assembly 8 connected to the dosing structure 7 will also rotate synchronously.

[0044] Furthermore, the mud pumping structure 4 includes a mud pump 41 fixedly arranged in the central column 3, mud pumping pipes 42 symmetrically fixedly arranged at both ends of the mud pump 41 and passing through both sides of the central column 3, and a mud discharge pipe 43 fixedly arranged at the bottom end of the pool body 1 and connected with the central column 3 and the bottom end of the mud pump 41. The mud pumping pipe 42 is fixedly connected to the central column 3.

[0045] Among them, in order to improve the effect of sludge extraction, the sludge extraction pipe 42 is fixedly connected to one side close to the bottom end of the tank body 1 with branch pipes 421 distributed in a linear array; the design of branch pipes 421 distributed in a linear array can more effectively cover the bottom of the tank body 1 to ensure that the sludge at the bottom end of the tank body 1 is extracted.

[0046] When it is necessary to pump out mud, start the driving structure 6 and the mud pump 41. At this time, the central column 3 will drive the branch pipe 421 to rotate in the tank body 1. At the same time, the mud pump 41 will start working and generate negative pressure or suction. Under the suction of the mud pump 41, the sludge at the bottom of the tank body 1 is sucked into the mud pumping pipe 42 through the branch pipe 421, and then transported to the mud discharge pipe 43 along the mud pumping pipe 42, and finally discharged from the tank body 1 through the mud discharge pipe 43, completing the sludge extraction process.

[0047] Furthermore, the transmission structure 77 includes a driving 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 arranged at the top of the central column 3 and meshing with one side of the driving 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 end of the push rod 75 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 driving gear 771 connected thereto to rotate. Since the driving gear 771 is meshed with the transmission gear 772, as the driving 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 with 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 motion of the push rod 75, so that the push rod 75, under the push of the connecting rod 776, will synchronously push the piston 74 to move back and forth, 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 close to the connecting rod 776, a connecting frame 82 fixedly arranged on one side of the sleeve plate 81 and located on one side of the medicine outlet pipe 76, and an impact plate 83 fixedly installed on one side of the connecting frame 82 close to the medicine outlet pipe 76;

[0050] When the push rod 75 pushes the piston 74 to move closer to the end of the medicine outlet pipe 76 so that the flocculant in the injection barrel 73 is added to the pool body 1 through the medicine outlet pipe 76, the sleeve plate 81 and the connecting frame 82 will also move synchronously to the side close to the medicine outlet pipe 76. At this time, the impact plate 83, driven by the connecting frame 82, will continue to approach the medicine outlet pipe 76. When the push rod 75 pushes the piston 74 to complete the approach to the end of the medicine outlet pipe 76, the sleeve plate 81 will contact the outer side of the injection barrel 73, and the impact plate 83 will collide with the medicine outlet pipe 76. Under the impact of the impact plate 83, a certain impact force will be generated, thereby prompting the residual flocculant in the medicine outlet pipe 76 to be discharged. Conversely, when the push rod 75 pushes the piston 74 to move toward the end away from the medicine outlet pipe 76, the impact plate 83 will also synchronously move away from the medicine outlet pipe 76.

[0051] In addition, in order to prevent wear, a gasket 831 is fixedly provided on one side of the impact plate 83 close to the medicine outlet pipe 76; the design of the gasket 831 can effectively prevent wear during the impact process, thereby extending the service life of the medicine outlet pipe 76 and the impact plate 83.

[0052] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
