Description

Technical Field

[0001] This utility model relates to the field of sedimentation tank technology, specifically to a sedimentation tank for sewage treatment with a scum removal structure. Background Technology

[0002] Wastewater sedimentation tanks are an important part of the wastewater treatment process. Their main function is to remove suspended solids and some dissolved substances from wastewater, thus achieving initial purification. The working principle of a wastewater sedimentation tank is based on gravity settling. When wastewater enters the sedimentation tank, the water flow slows down, and suspended solids (such as particulate matter and flocculent matter) gradually settle to the bottom of the tank under the influence of gravity, forming sludge. The relatively clean water overflows from the top of the tank and enters the next stage of the treatment process. In practical applications, wastewater sedimentation tanks are widely used in urban wastewater treatment, industrial wastewater treatment, and other fields.

[0003] Referring to Chinese Patent Publication No. CN219848282U, with the publication date of October 20, 2023, a sedimentation tank for sewage treatment is disclosed. The sedimentation tank for sewage treatment described in this utility model, by pulling a connecting slide, causes the tank wall cleaning strip to slide against the inner wall of the sedimentation tank body, while the connecting plate causes the tank bottom cleaning rod to slide against the inner bottom of the sedimentation tank body. This facilitates the removal of sludge adhering to the inner wall and bottom of the sedimentation tank body by the tank wall cleaning strip and the tank bottom cleaning rod, thereby making it easier for workers to clean the sludge on the inner wall and bottom of the sedimentation tank body in one go, thus improving the efficiency of sludge cleaning work.

[0004] However, during the use of this utility model, it is inconvenient to clean the floating scum inside the sedimentation tank. Since the scum floats on the water surface, it is also easy to be discharged when the treated sewage is discharged. Moreover, manually pulling the cleaning rod to clean the sedimentation tank is quite laborious. Therefore, there is still room for further improvement.

[0005] Therefore, we propose a sedimentation tank for wastewater treatment with a scum removal structure to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0031] This embodiment is a sedimentation tank for sewage treatment with a scum removal structure.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a slot 2 is provided on the inner side of the sedimentation tank body 1. The slot 2 is symmetrical about the vertical central axis of the sedimentation tank body 1. The slot 2 is slidably connected to the connecting rod 3. The connecting rod 3 is symmetrical about the vertical central axis of the collection frame 4. An inclined plate 5 is provided on the left side of the collection frame 4. The lower side of the collection frame 4 is threadedly connected to the first threaded rod 6. The first threaded rod 6 is rotatably connected to the sedimentation tank body 1. The first threaded rod 6 is fixedly connected to the output shaft of the first motor 7. The first motor 7 is fixedly connected to the sedimentation tank body 1.

[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, a second motor 8 is installed on the right side of the sedimentation tank body 1. The output shaft of the second motor 8 is fixedly connected to a second threaded rod 9, which is rotatably connected to the sedimentation tank body 1. The second threaded rod 9 is threadedly connected to a cleaning plate 10, which is tightly fitted to the sedimentation tank body 1. A drain outlet 11 is provided on the lower left side of the sedimentation tank body 1, which is rotatably connected to a baffle 12. A third motor 13 is installed on the upper side of the support plate on the front side of the sedimentation tank body 1. An active pulley 14 is installed on the outer side of the output shaft of the third motor 13. The active pulley 14 is connected to a belt body 15, which is connected to a first pulley 16 and a second pulley 17. The output shaft of the third motor 13, the first pulley 16, and the second pulley 17 are all fixedly connected to a stirring rod 18, which is rotatably connected to the sedimentation tank body 1.

[0034] It should be noted that a third motor 13 is installed on the front side of the sedimentation tank body 1. When the third motor 13 is working, the drive pulley 14 will rotate. The rotating drive pulley 14 will drive the first pulley 16 and the second pulley 17 to rotate through the belt body 15. Since the output shaft of the third motor 13 and the first pulley 16 and the second pulley 17 are all fixedly connected to the stirring rod 18, and the stirring rod 18 is located inside the sedimentation tank body 1, all the stirring rods 18 connected to it will rotate. This will help to accelerate the mixing of sewage and treatment agent inside the sedimentation tank, thereby reducing the reaction time. Therefore, sewage can be stirred over a large area, which is convenient to use. Specific Implementation Example 2

[0036] This embodiment is designed to address the problem of inconvenient cleaning of scum.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, the sedimentation tank body 1 has a slot 2 inside, and the slot 2 is slidably connected to the connecting rod 3. Therefore, the collection frame 4 can slide left and right inside the sedimentation tank body 1 through the slot 2 and the connecting rod 3. The slot 2 can prevent the connecting rod 3 from tilting and play a limiting role. In addition, the lower side of the collection frame 4 is threadedly connected to the first threaded rod 6. When the first motor 7 works, the first threaded rod 6 will rotate. The rotating first threaded rod 6 will cause the inclined plate 5 to move through the collection frame 4. The moving inclined plate 5 will collect the floating scum in the sedimentation tank body 1 into the collection frame 4 for easy cleaning.

[0038] In addition, the collection frame 4 is initially located inside the right side of the sedimentation tank body 1. After collecting and cleaning the scum, the collection frame 4 needs to be cleaned. Then, the first motor 7 is started to rotate the first threaded rod 6 in the opposite direction, so that the collection frame 4 is located inside the right side of the sedimentation tank body 1 again, which makes it convenient for the next scum treatment. Specific Implementation Example 3

[0040] This embodiment is designed to address the problem that manual cleaning of sludge on the lower side of the sedimentation tank body 1 is inconvenient.

[0041] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, after the sewage inside the sedimentation tank body 1 has been treated, the valve on the front side of the sedimentation tank body 1 is opened to discharge the sewage. Then, the second motor 8 is started. When the second motor 8 is working, the second threaded rod 9 will rotate. The rotating second threaded rod 9 will cause the cleaning plate 10 to move. Since the cleaning plate 10 is in close contact with the sedimentation tank body 1, the sludge adsorbed on the inside of the sedimentation tank body 1 will be cleaned to the inside left side of the sedimentation tank body 1. Then, the screw on the left side of the baffle 12 is opened, so that the baffle 12 is rotated and opened, and the sludge will be discharged from the sewage outlet 11 for easy treatment. Then, the second motor 8 is started, so that the second threaded rod 9 rotates in the opposite direction, so that the cleaning plate 10 is located back to the inside right side of the sedimentation tank body 1, which is convenient for the next sludge treatment.
