[0002] With the rapid development of industrialization and urbanization, the problem of sewage treatment has gradually surfaced and become a major problem affecting the sustainable development of society. As the urbanization process continues to advance, a large number of people have poured into cities, which has put huge pressure on urban sewage treatment. At the same time, the continuous expansion of industrial production has also brought a large amount of industrial wastewater, which has put forward higher requirements for sewage treatment technology.

[0003] Traditional sewage treatment methods, such as physical, chemical and biological methods, have solved the sewage problem to a certain extent, but they often have many disadvantages. Especially in the flocculation and sedimentation treatment of sewage, flocculants are mainly added to make the suspended matter in the sewage form larger particles, which is convenient for subsequent precipitation and filtration. However, the existing sedimentation and filtration technology often has problems such as low filtration efficiency and easy clogging, resulting in poor treatment effect and inability to efficiently separate the solid and liquid of sewage.

[0004] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a coagulation and sedimentation equipment for sewage treatment. Utility Model Content

In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution of a coagulation and sedimentation equipment for sewage treatment: comprising a sedimentation box 1, a sewage valve is installed at the bottom of the sedimentation box 1, a feeding port 12 is arranged on the outer wall of the sedimentation box 1, and a bracket 11 is installed at the bottom of the sedimentation box 1, a top seat 21 is arranged on the top of the sedimentation box 1, a mixing component is installed on the top seat 21, the mixing component comprises a mixing motor 22, a mixing shaft 23 is connected to the output end of the mixing motor 22, and the mixing shaft 23 passes through the top seat 21 and extends downward, a stirring blade 24 is arranged on the mixing shaft 23, and two groups of concave stirring frames 25 are symmetrically installed between the stirring blades 24, a top screen 26 is arranged on the top of the sedimentation box 1, and the top screen 26 is movably connected to the mixing shaft 23;

[0021] An overflow separation assembly is provided on the outer wall of the sedimentation box 1, and the overflow separation assembly includes an overflow box 3, an overflow hole 31 is provided through the overflow box 3, and the overflow hole 31 is communicated with the sedimentation box 1, an overflow plate 32 is provided in the overflow box 3, a mesh cylinder 33 is provided on the adjacent side of the overflow plate 32, a drain valve 34 is installed at the bottom of the mesh cylinder 33, the top screen 26 is located below the overflow hole 31, and the overflow hole 31 is located below the top wall of the overflow plate 32.

[0022] In this embodiment, the mixing shaft 23 is driven by the mixing motor 22 in the mixing assembly to drive the stirring blade 24 and the concave stirring frame 25 to rotate, thereby driving the sewage and flocculant inside the sedimentation tank 1 to be fully mixed, so that the suspended matter in the sewage is combined with the flocculant to form larger particles, which is convenient for subsequent sedimentation treatment. At the same time, the top screen 26 can intercept larger particles of impurities to prevent them from entering the subsequent filtering equipment, thereby reducing the risk of clogging of the equipment. In addition, through the overflow separation assembly, the supernatant after precipitation can enter the overflow box 3 through the overflow hole 31, and then pass through the overflow plate 32 to achieve further overflow filtration, and then pass through the mesh tube 33 for re-filtration, and finally be discharged through the drain valve 34, which further improves the sewage treatment effect.

[0023] It should be noted that the coagulation and sedimentation equipment for sewage treatment of the utility model can fully mix sewage and flocculants through the mixing components provided, so that the suspended matter and flocculants are combined to form larger particles, which is convenient for subsequent sedimentation treatment. At the same time, the top screen 26 and the overflow separation component provided can effectively intercept and filter impurities and improve the sewage treatment effect. In practical applications, the speed and working time of the mixing motor 22 and the feeding amount of the feeding port 12 can be adjusted as needed to meet the needs of sewage treatment of different scales and types. In addition, the coagulation and sedimentation equipment for sewage treatment of the utility model has a compact structure, simple operation, and is easy to maintain and maintain, and is suitable for various sewage treatment occasions.

[0024] The working principle and use process of the utility model are as follows: first, the sewage to be treated and an appropriate amount of flocculant are added to the sedimentation tank 1 through the feeding port 12. Then, the mixing motor 22 is started, and the mixing motor 22 drives the mixing shaft 23 to drive the stirring blade 24 and the concave stirring frame 25 to rotate inside the sedimentation tank 1, so that the sewage and the flocculant are fully mixed. During the mixing process, the suspended matter in the sewage combines with the flocculant to form larger particles, which is convenient for subsequent sedimentation treatment.

[0025] As the mixing process proceeds, larger impurities will be intercepted by the top screen 26 to prevent them from entering the subsequent filtering equipment, thereby reducing the risk of equipment clogging. At the same time, the mixed sewage is precipitated in the sedimentation tank 1, and larger impurities gradually settle to the bottom of the sedimentation tank 1.

[0026] After the sedimentation process is completed, the supernatant will enter the overflow box 3 through the overflow hole 31. In the overflow box 3, the supernatant passes through the overflow plate 32 again to achieve further overflow filtration, and is filtered again through the mesh tube 33 to remove residual fine impurities. Finally, the filtered supernatant is discharged through the drain valve 34, completing the sewage treatment process.

[0027] When needing to clean up the impurities at the bottom of the settling tank 1, the impurities at the bottom can be discharged by opening the drain valve. Meanwhile, the top screen 26 and the mesh cylinder 33 are cleaned up regularly to ensure its filtering effect.

[0028] In summary, the coagulation and sedimentation equipment for sewage treatment of the utility model realizes efficient sewage treatment and filtration through the coordinated use of the mixing component, the top screen 26 and the overflow separation component, and improves the sewage treatment effect. The equipment has a compact structure and is easy to operate, and is suitable for sewage treatment occasions of various sizes.
