Description

Technical Field

[0001] This utility model relates to the field of sedimentation tank technology, and in particular to a sewage sedimentation tank with anti-clogging function. Background Technology

[0002] A wastewater sedimentation tank is a wastewater treatment device that primarily removes suspended particles and sludge from water through gravity settling, achieving solid-liquid separation. Sedimentation tanks are widely used in the treatment of municipal wastewater and industrial wastewater (such as chemical and metallurgical wastewater). The main structure of a wastewater sedimentation tank includes the tank body, a stirring device, and an impurity filtration device. After prolonged use, a lot of impurities accumulate on the upper part of the impurity filter plate, causing clogging and reducing the filtration effect. Existing sedimentation tanks have added impurity cleaning plates and driving devices. The driving device moves the impurity cleaning plates to slide on the upper part of the impurity filter plate, which plays a certain role in cleaning impurities. However, it cannot clean the impurities inside the impurity filter plate, and a large amount of impurities still remain inside the impurity filter plate, causing clogging. Utility Model Content

An impurity discharge pipe 6 is connected to the bottom of the impurity cylinder 5. An impurity agitator 7 is installed at the lower end of the rotating shaft 2, with its bottom slidingly connected to the surface of the first filter grid 3. The bottom of the impurity discharge pipe 6 extends to the outside of the sedimentation tank 1 and is connected to an impurity pump 8. A water pipe 9 is installed circumferentially on the inner wall of the sedimentation tank 1 at the lower end of the first filter grid 3. Nozzles 10 are evenly spaced on the water pipe 9, spraying towards the first filter grid 3. A high-pressure water pump 11 connected to the water pipe 9 is installed outside the sedimentation tank 1. The sedimentation tank 1 serves as the main installation point for the sedimentation tank. The sedimentation tank 1 uses a first filter grid 3 to filter solid impurities in wastewater. The filtered wastewater flows to the bottom of the first filter grid 3. A rotating shaft 2, a rotary drive device, and an impurity agitator 7 are installed. The rotary drive device drives the impurity agitator 7 to rotate, and the impurity agitator 7 slides on the upper end of the first filter grid 3, thereby agitating the impurities on the upper end of the first filter grid 3, improving the flowability of the impurities, and facilitating the impurities to enter the impurity cylinder 5 through the connecting hole 4. An impurity discharge pipe 6 and an impurity pump 8 are installed. The impurity discharge pipe 6 is connected to the bottom of the impurity cylinder 5. The impurity pump 8 discharges the impurities inside the impurity cylinder 5 to the outside of the sedimentation tank 1 through the impurity discharge pipe 6. A water pipe 9, a nozzle 10, and a high-pressure water pump 11 are installed. The high-pressure water pump 11 transmits water through the water pipe 9 to the nozzle 10, and the nozzle 10 sprays a high-pressure water stream below the first filter grid 3. The high-pressure water stream carries away the impurities inside the first filter grid 3, thereby solving the problem of impurities clogging the impurity filter plate.

[0021] In this embodiment of the utility model, the first filter grid 3 is a cylindrical structure that gradually shrinks from top to bottom.

The bottom of the agitator plate 71 slides on the upper end of the first filter grid 3.

[0023] In an embodiment of this utility model, a plurality of stirring paddles 12 are provided at the upper end of the impurity stirring paddle 7 on the rotating shaft 2. By providing the stirring paddles 12, the rotating shaft 2 drives the stirring paddles 12 to rotate in the sewage, thereby increasing the fluidity of the sewage and facilitating the uniform sedimentation of impurities.

The outer edge of the baffle 52 is connected to the upper inner wall of the second filter grid 51, and the inner edge of the baffle 52 is located in the middle of the second filter grid 51. By setting the second filter grid 51 and the baffle 52, it is convenient for the sewage inside the impurity cylinder 5 to be discharged, reducing the moisture in the impurities and preventing the impurities from escaping from the upper end of the impurity cylinder 5. By setting the baffle 52, which is located on the upper inner wall of the second filter grid 51, it prevents the impurities inside the impurity cylinder 5 from moving upward, thereby improving the stability of the impurities in the impurity cylinder 5.

[0025] In an embodiment of this utility model, the baffle 52 is a structure in which the inner edge extends downward at an angle. By setting the baffle 52 to be a structure in which the inner edge extends downward at an angle, it is convenient for impurities to move downward along the inclined surface at the upper end of the baffle 52.

[0030] In use, firstly, wastewater is injected into the sedimentation tank 1 through the wastewater inlet pipe 15. Then, the drive motor 14 is started, and the output end of the drive motor 14 drives the rotating shaft 2 to rotate. The rotating shaft 2 drives the stirring paddle 12 and the impurity stirring paddle 7 to rotate. The stirring plate 71 slides on the upper end of the first filter grid 3, thereby stirring the impurities on the upper end of the first filter grid 3, improving the fluidity of the impurities, and making it easier for the impurities to enter the impurity cylinder 5 through the connecting hole 4. The wastewater inside the impurity cylinder 5 is discharged through the second filter grid 51, preventing the impurities inside the impurity cylinder 5 from moving upward. The impurity pump 8 discharges the impurities inside the impurity cylinder 5 to the outside of the sedimentation tank 1 through the impurity discharge pipe 6.
