However, for a long time, the traditional sedimentation tank design has exposed many problems in practical applications. The most prominent problem is the accumulation of sediments. Over time, these sediments will gradually accumulate at the bottom of the tank, seriously affecting the sedimentation effect and treatment capacity. At the same time, the cleaning of sediments is also a major problem, which often requires a lot of manpower and material resources for regular cleaning, and the operation process is complicated and cumbersome.

[0003] In view of the challenges faced by the above-mentioned traditional sedimentation tanks, we urgently need a new sedimentation tank technology solution to improve the sedimentation effect, simplify the cleaning process, and improve the overall convenience of operation.

[0037] This embodiment provides a large-scale sewage sedimentation tank, the structure of which is mainly composed of a sedimentation tank body 101, an upper frame 201, a sludge scraping mechanism and a sludge discharge system.

[0038] Sedimentation tank body 101:

[0039] The settling tank body 101 is designed as an inverted cone with an opening facing upward, and this shape is conducive to the natural sedimentation of heavy objects in the sewage to the bottom of the tank. A silt collecting tank body 102 is provided at the bottom center of the settling tank body 101 to collect the sludge and debris that are settled.

[0040] Upper frame 201 and core reduction motor 202:

[0041] An upper frame 201 is fixedly installed on the upper part of the sedimentation tank body 101, and its top projection presents a three-pointed star shape, which enhances the stability of the structure. A core reduction motor 202 is fixedly installed in the middle of the upper frame 201, and the output shaft of the motor extends downward to the bottom of the upper frame 201.

[0042] Scraping mechanism:

[0043] A rigid coupling 203 is provided below the upper frame 201, which is connected to the output shaft of the core reduction motor 202. A scraper mechanism 204 is installed below the rigid coupling 203, and the number thereof is set to a number according to actual needs, and these scraper mechanisms 204 are evenly arranged around the axis direction of the rigid coupling 203. Each scraper mechanism 204 is composed of an arc-shaped scraper plate body 205 and two connecting arms 206. The arc-shaped design of the scraper plate body 205 makes its scraping effect particularly excellent, and the connecting arms 206 at both ends are fixedly connected to the rigid coupling 203 together, ensuring the stable operation of the scraper mechanism 204. The bottom edge of the scraper plate body 205 is close to the upper surface of the sedimentation tank body 101, and the tangent of its lower end just passes through the top of the silt collecting tank body 102. This design is conducive to effectively scraping the sediment into the silt collecting tank body 102.

[0044] Sludge removal system:

[0045] On the inner wall of the sedimentation tank body 101, there is a long sludge discharge trough body 301, the lower part of which is connected and communicated with the sludge collecting trough body 102. The upper part of the long sludge discharge trough body 301 extends out of the sedimentation tank body 101, and its height exceeds the edge of the upper part of the sedimentation tank body 101. At the end of the long sludge discharge trough body 301, there is a downwardly inclined guide plate body 302 for guiding the sludge to flow out. At the same time, at the end of the upper part of the long sludge discharge trough body 301, an auxiliary reduction motor 306 is fixedly provided through an auxiliary plate body 303, and a spiral auger blade 304 is fixed on the output shaft of the motor. The extension direction of the spiral auger blade 304 is consistent with the extension direction of the long sludge discharge trough body 301, and it is all located in the long sludge discharge trough body 301, and the end extends into the sludge collecting trough body 102. In the silt collecting tank body 102, there is also a slanted block 305, and the end of the spiral auger blade 304 is rotatably connected to the slanted block 305. Such a design enables the sediment in the silt collecting tank body 102 to be effectively cleaned out.

[0046] Sewage inlet and sedimentation:

[0047] Sewage first flows into the sedimentation tank body 101 through the water inlet. Since the sedimentation tank body 101 is designed as an inverted cone, this structure is conducive to the natural sedimentation of heavy objects in the sewage to the bottom of the tank under the action of gravity. Over time, these sediments gradually accumulate and are then effectively scraped into the silt collection tank body 102 by the sludge scraping mechanism 204 for further treatment or removal.

[0048] Scraping operation:

[0049] When the sediment accumulates to a certain extent, the core reduction motor 202 starts to work. It drives the rigid coupling 203, and then drives the scraper mechanism 204 to rotate. In this process, the scraper plate 205 scrapes along the upper surface of the sedimentation tank body 101, effectively scraping off the sediment and pushing it to the silt collecting tank body 102. In this way, the scraper mechanism 204 can ensure the cleanliness of the bottom of the sedimentation tank body 101 and prevent excessive accumulation of sediment.

[0050] Sludge cleaning:

[0051] Once the sediment is collected in the sludge collecting tank 102, the next step is to clean the sludge. At this time, the auxiliary reduction motor 306 starts to operate, which drives the spiral auger blade 304 to rotate in the sludge discharge long tank body 301. The rotational movement of the spiral auger blade 304 generates an upward force, which gradually transports the sludge in the sludge collecting tank 102 upward. When the sludge reaches the end of the sludge discharge long tank body 301, the sludge is smoothly discharged out of the pool through the guidance of the guide plate body 302, thereby completing the entire sludge cleaning process.

[0052] Efficient scraping ability: The scraper body 205 scrapes along the upper surface of the sedimentation tank body 101, and its design ensures that the sediment can be effectively scraped off. This scraping action is not only thorough, but also can push the scraped sediment to the silt collecting tank body 102, thereby avoiding excessive accumulation and hardening of the sediment at the bottom of the tank. This advantage greatly improves the cleaning efficiency and service life of the sedimentation tank.

[0053] Excellent sludge cleaning mechanism: The spiral auger blade 304 driven by the auxiliary reduction motor 306 rotates in the sludge discharge long trough body 301 to generate an upward conveying force. This design can continuously and stably convey the sludge in the sludge collecting trough body 102 upward. When the sludge is conveyed to the end of the sludge discharge long trough body 301, the sludge can be smoothly discharged out of the pool with the guidance of the guide plate body 302. This process is automated and efficient, significantly reducing the need and cost of manual cleaning.

[0054] Easy operation and structural stability: The sedimentation tank system is very simple to operate and mainly relies on automated motor drive, reducing the complexity and labor intensity of manual operation.

[0055] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
