[0026] Example: A stirred sedimentation device for wastewater treatment, such as Figures 1-4As shown, the system includes a support base 1, a damper 2 is provided at the upper end of the support base 1, a shock-absorbing spring 3 is sleeved on the outer side of the damper 2, a support plate 4 is fixedly installed at the upper end of the damper 2, a stirring sedimentation tank 5 is fixedly installed at the upper end of the support plate 4, a drain pipe 6 is fixedly installed at the right end of the stirring sedimentation tank 5, the left end of the drain pipe 6 extends into the interior of the stirring sedimentation tank 5, a filter screen 7 is provided at the left end of the drain pipe 6, the filter screen 7 is connected to the inner wall of the stirring sedimentation tank 5 by fixing screws 8, a sewage pipe 9 is fixedly installed at the left end of the stirring sedimentation tank 5, and a sealing cap 11 is provided at the left end of the sewage pipe 9.

[0027] like Figures 1-4 As shown, a control valve 10 is installed in the middle of the drain pipe 6, and an inclined surface 12 is installed at the bottom of the stirring sedimentation tank 5. The inclined surface 12 is inclined towards the sewage pipe 9. A drive motor 13 is fixedly installed in the middle of the upper end of the stirring sedimentation tank 5, and a reagent inlet pipe 16 is fixedly installed at the left end of the upper end of the stirring sedimentation tank 5. A stirring shaft 14 is fixedly installed at the transmission end of the drive motor 13, and stirring rods 15 are fixedly installed at the left and right ends of the stirring shaft 14. Through the combination structure of the damper 2 and the shock absorption spring 3 on the support base 1, the vibration generated during the operation of the device can be effectively buffered, the impact of vibration on the connection of various components can be reduced, the problem of poor stability of the existing device can be solved, and the overall service life of the device can be extended.

[0028] like Figures 1-4 As shown, the front end of the stirring sedimentation tank 5 is provided with an inspection door 17, which is connected to the stirring sedimentation tank 5 by a hinge 18. A control switch 24 is provided at the right end of the stirring sedimentation tank 5. A transparent observation window 19 is provided in the middle of the inspection door 17. A convenient handle 20 is fixedly installed at the front end of the inspection door 17. The inspection door 17 and the stirring sedimentation tank 5 are locked together by a lock cylinder 21. A rubber sealing ring is provided at the connection between the inspection door 17 and the stirring sedimentation tank 5. Fixed support columns 22 are fixedly installed at the four corners of the bottom of the support base 1. Rubber anti-slip support pads 23 are fixedly installed at the lower end of the fixed support columns 22. The rubber anti-slip support pads 23 can increase the friction with the ground, improve the stability of the device when it is placed, and also play a certain role in shock absorption.

[0029] Working Principle: During use, first ensure the sealing cap 11 is closed. Introduce the wastewater to be treated into the mixing and sedimentation tank 5 through the reagent inlet pipe 16. Observe the wastewater level through the transparent observation window 19 to prevent overflow. Next, add the required flocculant and other reagents for wastewater treatment through the reagent inlet pipe 16 in proportion. Then, operate the control switch 24 to start the drive motor 13. The drive motor 13 drives the stirring shaft 14 to rotate, which in turn causes the stirring rod 15 to rotate. During the rotation of the stirring rod 15, the wastewater and reagents are fully mixed, accelerating the coagulation and sedimentation of suspended impurities in the water. During device operation, the vibration generated by the drive motor 13 is transmitted to the support plate 4, and then from the support plate 4 to the damper 2 and the shock-absorbing spring 3. The damper 2 consumes vibration energy through its own damping effect, while the shock-absorbing spring 3 further buffers vibration through elastic deformation. The combination of these two significantly reduces the impact of vibration on the entire device. At the same time, the fixed support column 22 and rubber anti-slip support pad 23 at the bottom of the support base 1 increase the friction with the ground, preventing displacement of the device during vibration and ensuring overall operation. To ensure stability, after a period of stirring and sedimentation, the drive motor 13 is turned off, and the sediment is allowed to settle to the bottom of the stirring sedimentation tank 5. At this time, the sediment will gradually gather towards the drain pipe 9 under the guidance of the inclined surface 12. After sedimentation is complete, the control valve 10 is opened by operating the control switch 24, and the treated clean water will flow to the drain pipe 6. When passing through the filter screen 7, the fine impurities remaining in the water are filtered and intercepted, and the filtered clean water is discharged from the drain pipe 6. When it is necessary to clean the sediment, the control valve 10 is closed first to prevent clean water from mixing with the sediment. The process is simple: first, the sealing cover 11 is opened, and the sediment near the drain pipe 9 is discharged from the drain pipe 9 under the combined action of gravity and the inclined surface 12. If internal maintenance is required, such as replacing the filter screen 7, the lock core 21 can be opened through the convenient handle 20, and then the maintenance door 17 can be opened using the hinge 18. The rubber sealing ring at the connection between the maintenance door 17 and the stirring sedimentation tank 5 ensures the seal when closed, preventing sewage leakage. The entire process is convenient to operate, has good treatment effect, and can effectively solve the problems existing in the current device.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
