It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. In the sewage treatment process, the flocculation process is an indispensable link, which makes the suspended particles in the water or liquid gather and become larger, or form flocs, thereby accelerating the coagulation of particles and achieving the purpose of solid-liquid separation.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: See Figure 1 The utility model provides a technical solution: a sewage treatment flocculation tank structure.

[0026] Among them, a second water reservoir 2 is arranged on the right side of the first water reservoir 1, and a third water reservoir 3 is arranged on the right side of the second water reservoir 2. An isolation plate 4 is arranged between the first water reservoir 1 and the second water reservoir 2, a filter plate 5 is arranged on the top of the isolation plate 4, and filter holes 6 are opened on the left and right sides of the filter plate 5. A lifting plate 7 is arranged at the bottom of the first water reservoir 1, a support plate 11 is arranged at the bottom of the lifting plate 7, a hydraulic rod 9 is arranged at the center of the bottom of the lifting plate 7 and passes through the support plate 11, and a hydraulic cylinder 10 is arranged at the bottom of the hydraulic rod 9.

[0027] In this embodiment, an isolation plate 4 is provided between every two water reservoirs to separate the water reservoirs, and the support plate 11 at the bottom is cross-shaped to protect the hydraulic rod 9 from tilting during lifting. The sewage is first in the first water reservoir 1. After the flocculant is added for full reaction, some impurities in the sewage will precipitate and form floccules. At this time, the hydraulic cylinder 10 is started, and the hydraulic rod 9 is raised to push the lifting plate 7 upward, and the sewage inside the first water reservoir 1 is also lifted. When the water level exceeds the isolation plate 4, the sewage will pass through the filter holes 6 on the filter plate 5 into the second water reservoir 2, while the floccules are unable to pass through the filter holes 5 due to their large size and are left in the first water reservoir 1. Flocculants are continued to be added to the sewage that has been filtered once in the second water reservoir 2, and the above operation is performed for secondary filtration.

[0028] The outer side of the lifting plate 7 is provided with a sealing groove, in which a sealing ring 8 is installed.

[0029] In this embodiment, the sealing ring 8 can isolate the sewage and prevent the sewage from seeping out from the gap between the lifting plate 7 and the water tank when the lifting plate 7 is raised or lowered, causing sewage leakage.

[0030] Among them, a flocculant tank 12 is fixedly connected to the back of the first water storage tank 1 , a feeding pipe 13 is arranged near the top of the inner wall of the first water storage tank 1 , and a hand wheel switch 14 is arranged above the feeding pipe 13 .

[0031] In this embodiment, a flocculant tank 12 is provided at the corresponding position of each water reservoir, and flocculant can be stored in the flocculant tank 12. One end of the feeding pipe 13 is bent 90 degrees to align with the bottom of the water reservoir, and the other end passes through the wall of the water reservoir and is connected to the flocculant tank 12. Turning on the handwheel switch 14 allows the flocculant to pass through the feeding pipe 13 and flow into the corresponding water reservoir. The amount of flocculant added can be controlled by the handwheel switch 14.

[0032] A water inlet 15 is provided on the left side of the first water reservoir 1 near the top, and a water outlet 16 is provided on the right side of the third water reservoir 3 near the bottom.

[0033] In this embodiment, the water inlet 15 is arranged at a high position to prevent sewage from flowing back, and the water outlet 16 is arranged at a low position to facilitate draining the water in the water reservoir.

[0034] The pore size of the filter hole 6 needs to be set according to the size of the flocculants.

[0035] In this embodiment, the filter plate 5 can be removed from the isolation plate 4 to replace the filter plate 5. Different sewage contains different impurities and the sizes of the generated flocs are also different. Therefore, the pore size of the filter hole used for filtration also needs to be changed accordingly to achieve the most ideal filtration effect.

[0036] Among them, the height of the isolation plate 4 between the second water reservoir 2 and the third water reservoir 3 is lower than the height of the isolation plate 4 between the first water reservoir 1 and the second water reservoir 2.

[0037] In this embodiment, each isolation plate 4 is shorter than the isolation plate 4 on the left, so that when the sewage in the reservoir is transferred to the right reservoir, it will preferentially flow to the side with the shorter isolation plate 4 to prevent the sewage from flowing back to the previous reservoir.

[0038] Among them, a corresponding water tank can be added to the right side of the third water tank 3 as needed.

[0039] In this embodiment, increasing the number of water storage tanks and corresponding facilities can increase the number of sewage filtration times to achieve the best filtration effect.

[0040] The multiple flocculant tanks 12 may store different types of flocculants.

[0041] In this embodiment, each flocculant 12 can store flocculants of the same specifications to filter sewage multiple times, or can store flocculants of different specifications to remove various impurities in the sewage, which can be independently controlled by the operator.

[0042] Working principle: sewage enters the first water reservoir 1 from the water inlet 15, turn on the hand wheel switch 14, and the flocculant in the flocculant tank 12 is put into the sewage in the first water reservoir 1 through the feeding pipe 13. After a period of sufficient reaction, some flocculants are precipitated in the sewage. At this time, the hydraulic cylinder 10 at the bottom of the first water reservoir 1 is started, and the hydraulic rod 9 is extended to lift the lifting plate 7 to push the sewage upward. When the sewage passes through the filter plate 5 above the isolation plate 4, it passes through the filter holes 6 on the surface of the filter plate 5 by gravity and flows into the second water reservoir 2 next to the first water reservoir 1. The flocculants in the sewage are blocked and retained in the first water reservoir 1 because their volume is larger than the filter holes 6. The sewage in the second water reservoir 2 that has been filtered once is mixed with the flocculant put down from the flocculant tank 12 of the second water reservoir 2 again, and reacts again. The above actions are repeated until it is filtered into the third water reservoir 3, and finally discharged through the water outlet 16 to complete the filtration. The operator cleans up the flocculants in each water reservoir and prepares for the next filtration.

[0043] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
