Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to an overflow well with active scum skimming. Background Art

[0002] With the development of sponge cities, more and more sponge facilities such as wet ponds and rain gardens are equipped in various parks and communities. As an important component of sponge facilities, the overflow well can basically only passively filter fallen leaves, scum, etc. in the sponge facilities in the case of overflow, and the cleaning effect is poor. Especially after the overflow ends, there is still a large amount of garbage in the sponge facilities.

[0003] Therefore, the utility model provides an overflow well with active scum skimming to solve the above technical problems. Content of the Utility Model

[0004] Utility Model Purpose: To solve the problem that in the prior art, as an important component of sponge facilities, the overflow well can basically only passively filter fallen leaves, scum, etc. in the sponge facilities in the case of overflow, and the cleaning effect is poor. Especially after the overflow ends, there is still a large amount of garbage in the sponge facilities.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An overflow well with active scum skimming, comprising:

[0007] An overflow well main body, in which a scum skimming component and a filtering component are arranged. The bottom of the overflow well main body is connected with a PE hose for discharging excess water into a water outlet. The overflow well main body is in the shape of a cylinder or a cuboid with an open upper end;

[0008] A floating body component, which includes a fixed rod and a floating body. The fixed rod is fixed at the upper end of the overflow well main body, and the floating body is fixed at the end of the fixed rod away from the overflow well main body. At least three groups of the floating body components are arranged on the overflow well main body, and the floating height of the floating body is higher than the height of the open end of the overflow well.

[0009] Further, the scum skimming component includes:

[0010] A scum skimming table, which is arranged at the opening of the overflow well main body, and its position is slightly lower than the opening of the overflow well. A fan-shaped water outlet hole is evenly opened in a circle of the scum skimming table. The scum skimming table is arranged in a concave shape, and several small holes are evenly arranged at the bottom of the scum skimming table;

[0011] A filter screen, which is arranged in a ring shape at the bottom of the fan-shaped water outlet hole.

[0012] Further, the filtering component includes:

[0013] The deflector plate is arranged below the filter screen;

[0014] The diversion pipe is arranged at the lower end of the deflector plate;

[0015] The filter element is arranged inside the diversion pipe, and the filter plate is arranged in a spiral shape.

[0016] Furthermore, the filter element is made of volcanic stone or activated carbon material.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] By arranging the floating body assembly higher than the main body of the overflow well, the liquid level is slightly higher than the main body of the overflow well, so that even in the case of no water overflow, the overflow well can still play the role of skimming scum. By arranging the PE hose at the bottom of the overflow well, while guiding water, the overflow well can float in the water and be restricted within a certain position range, avoiding excessive water overflow.

[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.

[0024] The applicant believes that in the prior art, as an important component of the sponge facility, the overflow well can basically only passively filter the fallen leaves, floating scum, etc. in the sponge facility in the case of water overflow, and the cleaning effect is poor. Especially after the water overflow ends, there is still a large amount of garbage in the sponge facility.

[0025] Therefore, the applicant designs as Figures 1 - 3An overflow well with active skimming shown in the figure includes: an overflow well main body 1, in which a skimming component and a filtering component are arranged; a PE hose 2 connected to the bottom of the overflow well main body 1 for discharging excess water into the sewer outlet; the overflow well main body 1 is a cylinder or a cuboid with an open upper end; a floating body 3 component, which includes a fixed rod 4 and a floating body 3. The fixed rod 4 is fixed at the upper end of the overflow well main body 1, and the floating body 3 is fixed at the end of the fixed rod 4 away from the overflow well main body 1. At least three groups of floating body 3 components are arranged on the overflow well main body 1, and the floating height of the floating body 3 is higher than the height of the open end of the overflow well.

[0026] Further optionally, in the overflow well with active skimming of this embodiment, the skimming component includes: a skimming table 5, which is arranged at the opening of the overflow well main body 1, slightly lower than the opening of the overflow well. A fan-shaped drain hole 501 is evenly opened in a circle on the skimming table 5. The skimming table 5 is arranged in a concave shape, and several small holes are evenly arranged at the bottom of the skimming table 5; a filter screen 6, which is arranged in a ring shape at the bottom of the fan-shaped drain hole 501.

[0027] Further optionally, in the overflow well with active skimming of this embodiment, the filtering component includes: a guide plate 7, which is arranged below the filter screen 6; a guide pipe 8, which is arranged at the lower end of the guide plate 7; a filter element 9, which is arranged in the guide pipe 8, and the filter plate is arranged in a spiral shape.

[0028] Even further optionally, the filter element 9 is made of volcanic stone or activated carbon. Both activated carbon and volcanic stone have a porous structure, with a small pore size and a large surface area, which can adsorb and accumulate some fine particulate matter and organic matter. In addition, both the surface of activated carbon and volcanic stone have negatively charged functional groups, which can adsorb positively charged ions, heavy metal ions, etc., and remove them through electrostatic action. The physical adsorption process of activated carbon and volcanic stone is an irreversible process. Once adsorbed on activated carbon and volcanic stone, it is very difficult to release them again. Therefore, it has good stability.

[0029] Working principle: Place the overflow well main body 1 in water. Since the floating height of the floating body 3 is slightly higher than the upper end of the overflow well main body 1, the sundries floating on the water surface will flow to the lower place due to the action of gravity, that is, into the overflow well main body 1. The skimming table 5 in the overflow well main body 1 will retain some sundries, and other smaller sundries will continue to be filtered in the overflow well main body 1 through the filter screen 6 and the filter element 9. The spiral filter element 9 can filter the sewage multiple times; the filtered sewage is discharged into the sewer through the PE hose 2. Since the overflow well itself has a certain height and a certain weight, when the liquid level drops to a certain height, it will be lower than the height of the overflow well main body 1, and water will no longer flow into the overflow well, avoiding dryness caused by excessive water flow.

[0030] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
