[0002] With the development of social economy and the acceleration of the industrialization process, the problem of water pollution has become increasingly serious. The shortage of water resources and the deterioration of the water environment have become important challenges faced globally. Effective water treatment technologies play a crucial role in improving water quality, protecting the ecological environment, and realizing the sustainable utilization of water resources. As an important link in the water treatment system, the sedimentation tank undertakes the task of removing suspended solids and particulate matters in water.

[0003] However, it has been found in the use of traditional sedimentation tanks that if the water body is not pretreated, the residual garbage, suspended solids, etc. in the sewage will lead to problems such as low treatment efficiency and slow sedimentation speed. In order to improve the treatment effect of the sedimentation tank, it is necessary to design an efficient and convenient pre-multi-stage treatment device to improve the water treatment effect and reduce the burden on the subsequent sedimentation tank. Summary of the Utility Model

Specific implementation mode

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Embodiment 1:

[0026] Combined with Figures 1-3 A pre - multi - stage treatment device for a water treatment sedimentation tank shown in the figure, including a support frame 1. A primary filtration device 2 and a chemical agent mixing device 3 are respectively arranged on the support frame 1. The primary filtration device 2 is located above the chemical agent mixing device 3 to ensure the smooth transfer of water flow. A sedimentation tank 4 is arranged on one side of the chemical agent mixing device 3 to facilitate the collection and precipitation of the treated water body;

[0027] The primary filtration device 2 includes a primary filtration main body 201. Driving rollers 202 are rotatably arranged at both ends of the upper surface of the primary filtration main body 201. A first filter screen 203 is arranged between the two groups of driving rollers 202 to effectively intercept larger - particle pollutants and garbage. A driving motor 204 for controlling its rotation is arranged on one side of one of the driving rollers 202, which can automatically control the rotation of the driving roller 202 so that the first filter screen 203 rotates, ensuring the effective transfer of garbage and larger - particle pollutants on the surface of the first filter screen 203 to avoid clogging the filter screen holes. A second filter screen 205 is arranged in the cavity of the primary filtration main body 201 to further improve the filtration accuracy. A number of groups of first drainage pipes 206 are arranged on the outer side wall of the bottom of the primary filtration main body 201 to ensure the efficient discharge of the filtered water;

[0028] The medicament mixing device 3 includes a medicament mixing main body 301. Above the cavity of the medicament mixing main body 301, a support beam 302 is provided to provide necessary structural support. A number of groups of stirring motors 303 are evenly distributed on the support beam 302. On the rotating shaft of the stirring motor 303, stirring blades 304 are provided. The design of these blades not only increases the mixing efficiency but also ensures sufficient contact between the medicament and water. Between adjacent two groups of stirring blades 304, a partition plate 305 is provided. On the partition plate 305, through holes 306 are provided to promote the hydrodynamic efficiency during the mixing process and also can constitute the separate independent addition of different medicaments to ensure the progressive orderly progress. On the outer side wall of the medicament mixing main body 301, a second drainage pipe 307 and a first sewage discharge pipe 308 are respectively provided. The second drainage pipe 307 is located above the first sewage discharge pipe 308. The reasonable pipeline layout ensures that the water body after medicament mixing can be quickly discharged or further processed, realizing the high efficiency and practicability of multi-stage water treatment. For example, the second drainage pipe 307 ensures the smooth transfer of the water body after medicament mixing, and the first sewage discharge pipe 308 quickly clears and discharges the sediment and deposited dirt at the bottom of the cavity of the medicament mixing main body 301 to avoid secondary pollution or affecting subsequent operations.

[0029] In this embodiment, a number of groups of support bottom plates 5 are provided at the bottom of the support frame 1. The support bottom plates 5 not only provide a solid foundation for the whole device but also effectively disperse the weight of the equipment to improve the bearing capacity and compressive performance of the structure. A number of threaded holes are opened on the support bottom plates 5. The design of these threaded holes is to facilitate the fixing and installation of the equipment.

[0030] In this embodiment, the aperture of the first filter screen 203 is larger than that of the second filter screen 205. This design concept aims to achieve an efficient multi-stage filtration process. Specifically, the first filter screen 203, as the first line of defense of the primary filtration device, is mainly responsible for capturing larger particle pollutants and garbage impurities, such as suspended solids, leaves and other visible particles. The larger aperture can ensure smooth water flow, high passing rate and reduced flow resistance, thus ensuring the high efficiency of primary filtration. After the water flow passes through the first filter screen 203, smaller impurities will be brought into the cavity of the primary filtration main body 201. At this time, the second filter screen 205 plays its important role. Due to its relatively small aperture, the second filter screen can effectively intercept finer particulate matters and pollutants, such as algae, to further improve the purification degree of water quality. This hierarchical filtration method not only enhances the filtration efficiency but also extends the service life of the equipment because the first filter screen 203 can first handle large particle pollutants and reduce the burden on the second filter screen 205.

[0031] In this embodiment, the bottom of the agent mixing main body 301 is inclined. The inclined setting ensures that when there are some sediment or inclined precipitates in the agent mixing, along with the inclination of the bottom of the agent mixing main body 301, it is brought to the first sewage discharge pipe 308 for convenient subsequent cleaning.

[0032] In this embodiment, there are at least three groups of blades of the stirring blade 304. This multi-group configuration can provide stronger stirring power during the agent mixing process to ensure the full mixing of the agent and water. There is an included angle between the blades of the stirring blade 304 and the horizontal plane. This design not only optimizes the stirring efficiency but also effectively improves the fluidity and mixing uniformity of the liquid. By setting the included angle, the stirring blade 304 can generate an upward flow when rotating, causing the liquid to form an effective flow within the agent mixing main body 301, promoting the agent to quickly come into full contact with the water body and react.

[0033] In this embodiment, a sewage discharge hole 309 is provided at the bottom of the partition plate 305. During the agent mixing and water treatment processes, some precipitates and sediment will inevitably be generated when the liquid flows. If these precipitates are not removed in time, it may affect the mixing effect and the normal operation of the equipment. The sewage discharge hole 309 ensures the effective flow of the precipitates to the first sewage discharge pipe 308.

[0034] In this embodiment, a second sewage discharge pipe 6 is provided on the outer side wall of the bottom of the sedimentation tank 4, which is convenient for the regular cleaning of the sedimentation tank 4. It not only optimizes the sewage discharge process of the sedimentation tank 4 but also provides strong support for the efficient operation of the water treatment system.
