Description

Technical Field

[0001] This utility model relates to the technical field of sewage purification and treatment equipment, and in particular to a sewage sedimentation tank system. Background Technology

[0002] Settling is a crucial step in wastewater treatment. Wastewater settling typically occurs in settling tanks. Wastewater is introduced into these tanks and allowed to settle for a period (this can be done after adding flocculants). Settled pollutants in the wastewater will then settle to form precipitates, which are then pumped to the next stage for further purification. The precipitates can also be pumped to subsequent stages for drying and other treatments. In practice, a large amount of scum may float on the surface of the wastewater during settling, requiring removal (usually using scoops to remove the scum from the settling tank). Currently, scum removal is generally done manually. However, if the amount of scum is large and covers most of the settling tank surface, this significantly increases the workload, is time-consuming and labor-intensive, and inefficient. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a sewage sedimentation tank system that solves the problem of low efficiency in removing large amounts of scum in existing technologies.

[0004] According to an embodiment of this utility model, a sewage sedimentation tank system includes a first receiving tank, a second receiving tank with a first common wall between the first receiving tanks, and a third receiving tank with a second common wall between the second receiving tanks. The top surface of the first common wall is higher than the top surface of the second common wall. The system also includes an inclined guide plate with its higher end fixed to the first common wall and its lower end fixed to the top surface of the second common wall, located below the top surface of the second common wall. The inclined guide plate also has several through holes connecting the space above it and the second receiving tank. When it is necessary to separate scum, the scum is pushed towards the first common wall, over the inclined guide plate, and then into the third receiving tank. This process is faster and less labor-intensive, thus solving the problem of low efficiency in removing large amounts of scum in the prior art.

[0005] Furthermore, it also includes a scraper that can be placed on an inclined guide plate, and the scraper is connected to a pull rod.

[0006] Furthermore, the third containment pool is provided with perforations through which the pull rod can pass.

[0007] Furthermore, the tie rod has a Z-shaped structure.

[0008] Furthermore, the top surface of the scraper is inclined, and the higher end can be flush with or lower than the top surface of the first common wall.

[0009] Furthermore, the inclined guide plate extends into the third containment pool.

[0010] Furthermore, an intercepting plate is also installed above the top surface of the first common wall. The intercepting plate includes an installation strip and several intercepting rods that are equidistantly arranged along the axial direction of the installation strip and fixedly connected to the installation strip.

[0011] Furthermore, an installation plate is fixedly connected above the first common wall. Telescopic actuators are installed at both ends of the installation plate, and the telescopic actuators have downward telescopic ends. Connecting rods are fixedly installed between the two telescopic ends and the installation strip.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] When separating scum, there is no need to scoop it out. Instead, the scum is moved towards the first common wall and then across it, making the operation more convenient, labor-saving, and time-saving. This solves the problem of low efficiency in removing large amounts of scum in existing technologies. The scum can move more easily to the third receiving tank on the inclined guide plate for unified treatment. In addition, the wastewater that moves with the scum can pass through the inclined guide plate into the second receiving tank, preventing the scum in the third receiving tank from containing more wastewater and facilitating separate treatment.

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] In an exemplary implementation, such as Figure 1 , 2 As shown, this embodiment provides a sewage settling tank system, which includes a first receiving tank 1, a second receiving tank 3 with a first common wall 2 between the first receiving tanks 1, and a third receiving tank 5 with a second common wall 4 between the second receiving tanks 3. An inlet pipe 6 is provided on the first receiving tank 1 for introducing sewage to be treated. The sewage undergoes settling treatment in the first receiving tank 1. Specifically, the sewage in the first receiving tank 1 can be filled to the point where the liquid level is equal to (slightly lower than) the top surface of the first common wall 2, and the top surface of the first common wall 2 is higher than the top surface of the second common wall 4. An inclined guide plate 7 is also included, with its higher end fixed to the first common wall 2 and its lower end fixed to the top surface of the second common wall 4, and the inclined guide plate 7 is located below the top surface of the second common wall 4. The inclined guide plate 7 is also provided with several through holes connecting the space above it and the second receiving tank 3. When separating the foam, it is not necessary to scoop out the foam. The foam can be moved towards the first common wall 2 and passed over the first common wall 2 onto the inclined guide plate 7. The operation is more convenient, labor-saving and time-saving, which solves the problem of low efficiency in removing large amounts of foam in the prior art. The foam can move more easily to the third receiving tank 5 on the inclined guide plate 7 for unified treatment. In the process, the less sewage that moves with the foam can also pass through the inclined guide plate 7 into the second receiving tank 3, so that the foam in the third receiving tank 5 does not contain more sewage, which is convenient for separate treatment. The inclined guide plate 7 extends to the third receiving tank 5, so that the foam can reach the third receiving tank 5 more smoothly.

[0022] like Figure 1-3As shown, this scheme also includes a barrier plate that is raised and lowered above the first common wall 2. The barrier plate includes an installation strip 8 and several barrier rods 9 that are equidistantly arranged along the axial direction of the installation strip 8 and fixedly connected to the installation strip 8. These barrier rods 9 are spaced apart from each other and can abut against the top surface of the first common wall 2. When it is necessary to separate the foam, some clean water can be introduced through the water inlet pipe 6 to raise the water level in the sewage tank. The rising water can pass through the barrier rods 9, and the barrier rods 9 can be set relatively close to intercept a small amount of foam. As the water continues to pass through the barrier rods 9, more foam will move towards the barrier rods 9 and be intercepted near the barrier rods 9. When most of the foam is intercepted together, the barrier plate is raised, so that most of the foam can reach the inclined guide plate 7 more quickly, further improving efficiency. After the foam (or water) reaches the inclined guide plate 7, the water can pass down through the through hole to the second receiving tank 3, while the foam moves to the third receiving tank 5. Furthermore, a scraper 10 can also be set to assist. The foam on the inclined guide plate 7 moves to the third receiving tank 5. The scraper 10 is also fixedly connected to a Z-shaped pull rod 11. The pull rod 11 can make the scraper 10 scrape on the inclined guide plate 7, so that the foam can enter the third receiving tank 5 more quickly. In particular, the scraper 10 can be placed on the higher end of the inclined guide plate 7, and the top surface of the scraper 10 is inclined, and the higher end can be flush with or lower than the top surface of the first common wall 2, so as not to affect the foam from crossing the inclined guide plate 7. At the same time, the pull rod 11 can move the scraper 10 on the inclined guide plate 7. The Z-shape of the rod 11 can include a first horizontal bar 12, a second horizontal bar 13, and a vertical bar 14 connecting them. The first horizontal bar 12 is fixedly connected to the scraper 10, the second horizontal bar 13 is located above the first horizontal bar 12, and the vertical bar 14 can have an orthographic projection within the second receiving pool 3. This can prevent water from flowing down the pull rod 11 into the third receiving pool 5. The third receiving pool 5 is provided with a perforation 15, through which the pull rod 11 can pass, which facilitates operation outside the third receiving pool 5.

[0023] like Figure 1-3 As shown, a mounting plate 16 is further fixedly connected above the first common wall 2. Telescopic actuators 17 are installed at both ends of the mounting plate 16, and the telescopic actuators 17 have downward telescopic ends. Connecting rods 18 are fixedly provided between the two telescopic ends and the mounting strip 8. The telescopic actuators 17 can be cylinders, electric push rods, or other devices that can drive up and down movement, so that the interceptor plate can be raised and lowered.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
