Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically to a purification device for urban sewage treatment. Background Art

[0002] Urban sewage refers to domestic sewage of urban residents, as well as drainage from organs, schools, hospitals, commercial service institutions and various public facilities, and also includes industrial wastewater and initial rainwater that are allowed to be discharged into the urban sewage collection system.

[0003] Urban sewage usually needs to use a sedimentation tank to precipitate and filter impurities in the sewage. When precipitating, usually alum and other substances are put in to react with water to generate flocculants, which adsorb impurities to sink to the bottom. However, the existing sedimentation tanks cannot evenly put alum in the sedimentation tank, resulting in some impurities still being discharged with the water, interfering with the secondary purification. Content of the Utility Model

[0022] Further, the powder spreading assembly 503 includes a powder spreading box 5031. The powder spreading box 5031 is of a hollow structure. Powder discharge holes 5032 are formed in the four circumferences of the powder spreading box 5031. The top of the powder spreading assembly 503 is fixedly connected with a blanking pipe 502. The top of the blanking pipe 502 is fixedly connected with a powder storage box assembly 501. When the powder spreading assembly 503 rotates, the alum powder in the powder spreading box 5031 is discharged from the powder discharge holes 5032 under the action of centrifugal force when the powder spreading box 5031 rotates, and is evenly sprinkled on the top of the water flow in the inlet pipe 2.

[0023] Further, a vertical rod bracket 401 is movably sleeved inside the connecting ring 402. A bearing is provided at the connection between the connecting ring 402 and the vertical rod bracket 401. The bottom of the vertical rod bracket 401 is fixedly connected with the inner bottom wall of the sedimentation tank 1. When sewage rushes into the sedimentation tank 1, the impact force of the sewage can push the fan blades 403 to rotate, thereby driving the connecting ring 402 to rotate. At this time, the vertical rod bracket 401 remains stationary, and the vertical rod bracket 401 plays a role in supporting and fixing the fan blades 403 and the connecting ring 402.

[0024] Further, the powder storage box assembly 501 includes a box body 5011, the box body 5011 is a hollow structure, a feeding port 5012 is fixedly connected to the top of the box body 5011, and a cover 5013 is movably connected to the top of the feeding port 5012.

[0025] Further, a round hole is provided at the top of the powder sprinkling box 5031, a round hole is provided at the bottom of the box body 5011, and the top and bottom of the feeding pipe 502 are fixedly connected to the round hole of the box body 5011 and the round hole of the powder sprinkling box 5031 respectively; the box body 5011, the feeding pipe 502 and the powder sprinkling box 5031 are communicated with each other to ensure that the alum powder can be normally fed downward.

[0026] Further, a round hole is provided at the top of the cross bar bracket 6, the feeding pipe 502 is located inside the round hole of the cross bar bracket 6, a connecting block is provided at the bottom of the box body 5011, and the connecting block of the box body 5011 is fixedly connected to the top of the cross bar bracket 6; the cross bar bracket 6 supports and fixes the feeding assembly 5.

[0028] Specifically, as Figure 5 shown, the center of the fan blade 403 and the center inside the water inlet pipe 2 are on the same horizontal line. When the sewage rushes into the sedimentation tank 1, the impact force of the sewage can push the fan blade 403 to rotate, thereby driving the connecting ring 402 to rotate. When the connecting ring 402 rotates, it drives the powder sprinkling assembly 503 to rotate together. The back of the connecting ring 402 and the front of the round hole of the sedimentation tank 1 are on the same straight line. The distance from one side of the connecting ring 402 to the inner wall of the sedimentation tank 1 has a tolerance fit with the length of the fan blade 403, ensuring that the fan blade 403 will not be restricted by the inner wall of the sedimentation tank 1 when rotating and also ensuring that the fan blade 403 is closest to the water inlet pipe 2 at this time, ensuring that the impact force can push the fan blade 403

[0029] Working principle of the utility model: A driving assembly 4 is provided at the connection between the water inlet pipe 2 and the sedimentation tank 1. When the water inlet pipe 2 is driven by the sewage pump in the water inlet pipe 2, water flows through the extraction of the sewage pump in the water inlet pipe 2 and is discharged from the water inlet pipe 2 into the sedimentation tank 1 at a certain speed. At this time, the water flow has a certain impact force, and the center of the fan blade 403 is on the same horizontal line as the inner center of the water inlet pipe 2. When the sewage rushes into the sedimentation tank 1, the impact force of the sewage can push the fan blade 403 to rotate, thereby driving the connecting ring 402 to rotate. When the connecting ring 402 rotates, it drives the powder spreading assembly 503 to rotate together. The alum powder in the powder spreading box 5031 is discharged from the powder discharging hole 5032 under the action of centrifugal force when the powder spreading box 5031 rotates, and is evenly sprinkled on the top of the water flow in the water inlet pipe 2. Alum is put into the water flow when it enters, so that the alum is evenly distributed in the sewage to be sedimented. After sedimentation and reaction, the floccules generated by the alum adsorb and precipitate the impurities at the bottom of the sedimentation tank 1, and the clear water at the top of the sediment is discharged through the drain pipe 3, realizing the uniform feeding of alum and ensuring that all impurities can be effectively sedimented.
