Description

Technical Field

[0001] This utility model relates to the field of sedimentation tank technology, and in particular to a wastewater sedimentation tank. Background Technology

[0002] Wastewater sedimentation tanks are an important component of wastewater treatment, primarily used to remove suspended solids and sediments from wastewater. Through gravity, after wastewater enters the sedimentation tank, solid particles gradually settle to the bottom in a static state, thereby purifying the water. The application of this technology stems from the importance attached to water pollution problems. Sedimentation tanks can effectively reduce the concentration of pollutants in water during the treatment process, thus protecting water resources, improving the ecological environment, promoting technological progress and equipment upgrades in this field, and facilitating the implementation of more advanced wastewater treatment processes.

[0003] A search revealed Chinese Patent Publication No. CN219043171U, which discloses a wastewater sedimentation tank comprising a mixing zone, an intermediate tank, and an effluent zone. The intermediate tank, from top to bottom, includes a clear water zone, an inclined tube filtration zone, and a sedimentation zone. The inclined tube filtration zone has a parallelogram cross-section and contains inclined tube components. A mixing zone is located on one side of the intermediate tank and is connected to the sedimentation zone via a pipeline. A first connecting groove is located on the side of the effluent zone, and a second connecting groove is located above the side plate of the clear water zone. The bottom surface of the second connecting groove in the clear water zone is on the same horizontal plane as the bottom surface of the first connecting groove. The wastewater overflows into the effluent zone through the first connecting groove on the side of the effluent zone and the second connecting groove above the side plate of the clear water zone, and is discharged from the drain outlet. However, this structure does not consider the blockage caused by settled sludge, requiring regular cleaning. Manual cleaning is inefficient and ineffective, failing to meet usage requirements. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a wastewater sedimentation tank, which aims to improve the problem that sediment in the prior art easily causes pipe blockage, and manual cleaning is slow, ineffective, and increases labor costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wastewater sedimentation tank, comprising a tank body, a primary sedimentation tank disposed on the top left side of the tank body, a secondary sedimentation tank disposed in the top middle of the tank body, and a tertiary sedimentation tank disposed on the top right side of the tank body. Multiple inclined surfaces are provided at the bottom of the inner wall of the tank body. A sludge scraper is slidably connected to the top of the left inclined surface. A connecting rod is fixedly connected to the top of the sludge scraper. A sliding plate is fixedly connected to the top of the connecting rod. A sliding frame is slidably connected to the top of the outer wall of the sliding plate. Connecting plates are fixedly connected to the top of the front and rear sides of the inner wall of the tank body. Multiple telescopic rods are fixedly connected to the left and right sides of the connecting plates. A sludge removal mechanism is provided on the inner wall of the tank body, which is used to remove and clean the internal sludge.

[0006] The above technical solution utilizes a three-stage sedimentation system: the tank body, the main component of the entire structure, is divided into primary, secondary, and tertiary sedimentation tanks.

A sliding frame is connected to the top of the outer wall, which further enhances the flexibility and ease of operation of the scraper. To further enhance the structural stability of the pool, connecting plates are fixedly connected to the top of the front and rear sides of the inner wall. These connecting plates provide additional support and connection points for the entire pool. Multiple telescopic rods are fixedly connected to the left and right sides of the connecting plates. These telescopic rods can operate the scraper as needed to adapt to different operational requirements. The inner wall of the pool is equipped with a sludge discharge mechanism, which is a device specifically used to extract and clean the sludge inside the pool, ensuring the cleanliness and maintenance of the entire sedimentation tank.

The bottom end of the sludge discharge pipe is also connected to a sludge pump via a fixed connection, ensuring smooth sludge discharge. The bottom end of the sludge pump is also connected to the sludge pump via a fixed connection. The outer wall of the sludge pump is evenly provided with multiple sludge suction ports, designed for more efficient sludge-water separation. A sludge discharge port is also fixedly connected to the rear end of the top of the sludge discharge pipe to facilitate the discharge of sludge and water. To further treat and store the discharged sludge and water, a sludge storage tank is fixedly connected to the rear of the tank, effectively collecting and storing the sludge discharged from the sedimentation tank.

[0043] Please see the appendix Figure 1 and attached Figure 4A support plate 13 is fixedly connected to the rear side of the middle of the top of the pool body 1. A support frame 14 is fixedly connected to the right side of the top of the support plate 13. A control box 15 is fixedly connected to the top of the support frame 14. A door 16 is rotatably connected to the front side of the control box 15. An observation window 17 is provided on the front side of the door 16. A protective cover 18 is fixedly connected to the top of the control box 15.

[0045] Please see the appendix Figure 1 and attached Figure 5 A fixed column 19 is fixedly connected to the top rear side of the tank body 1, and a ladder 20 is fixedly connected to the rear end of the fixed column 19. A primary water inlet pipe 21 is fixedly connected to the top left side of the primary sedimentation tank 3. A secondary water inlet pipe 22 is fixedly connected to the top left side of the secondary sedimentation tank 4. A tertiary water inlet pipe 23 is fixedly connected to the top left side of the tertiary sedimentation tank 5. An outlet pipe 24 is fixedly connected to the top right side of the tertiary sedimentation tank 5.

[0046] Specifically, a fixed column 19 is securely connected to the top rear side of the tank 1.

On the top left side of the tertiary sedimentation tank 5, a tertiary water inlet pipe 23 is also fixedly connected, which continues to introduce the water treated by the secondary sedimentation into the tertiary sedimentation tank 5 to complete the entire sedimentation process. On the top right side of the tertiary sedimentation tank 5, we see a fixed water outlet pipe 24, which is responsible for discharging the clear water treated by the tertiary sedimentation for subsequent use.

[0047] Working principle: A primary sedimentation tank 3, a secondary sedimentation tank 4, and a tertiary sedimentation tank 5 are formed in the tank body 1 for graded treatment of wastewater. An inclined surface 6 is formed on the inner wall of the tank body 1 to promote the accumulation of sludge. A scraper 7 is installed on the surface of the inclined surface 6. The scraper 7 is scraped by controlling its movement. A connecting rod 8 is fixedly connected to the top of the scraper 7. A sliding plate 9 is connected to the connecting rod 8. Since the sliding plate 9 slides on the inner wall of the slide frame 10, and the connecting plate 11 is fixed to the inner wall of the tank body 1 and connected to the middle of the slide frame 10, the telescopic rod 12 connected to the connecting plate 11 is rotated. This causes the sliding plate 9, which is rotatably connected to the other end of the telescopic rod 12, to move left and right. This drives the connecting rod 8 to make the scraper 7 slide on the surface of the inclined surface 6, thereby pushing the sludge to the middle. This structure can collect sludge, improve the sludge cleaning speed, avoid the accumulation and blockage, and meet the cleaning requirements.

[0048] By connecting sludge discharge pipes 201 within each sedimentation tank and connecting sludge pumps 202 to the bottom of sludge discharge pipes 201, and the bottom of sludge pumps 202 being fixedly connected to sludge pumping pipes 203 for pumping out sludge, and opening sludge pumping ports 204 on the outer wall of sludge pumping pipes 203, the range of sludge pumping is widened, ensuring that all sludge is pumped out. After being pumped out, it is discharged through sludge discharge pipes 201 and discharged from the sludge discharge port 205 at the top of the pipes 201. A sludge storage tank 206 is set after the sedimentation tank to store the sludge discharged from the sludge discharge port 205. This structure can automatically pump out the cleaned sludge, ensuring timely, stable and efficient sludge discharge, improving sludge discharge efficiency, reducing labor costs, and meeting sludge discharge requirements.
