Description

Shutting assembly for separation of first rain and non-point source a contaminant purification system of first rain having this}

The present invention relates to an opening and closing assembly for initial excellent separation and an initial excellent non-point pollutant treatment system including the same, and more particularly, for initial excellent separation for separating and purifying an initial excellent water containing a large amount of non-point pollutant during rainfall. Opening and closing assembly and an excellent initial non-point pollutant treatment system comprising the same.

Water sources are largely divided into point sources and nonpoint sources. Point sources are mainly traceable to the origin and volume of livestock sewage from households or business areas, industrial wastewater from factories, and livestock wastewater from large livestock facilities. These relatively easy ones are the main targets for sewage treatment.

On the other hand, nonpoint source refers to drainage from agricultural drainage, mine wastewater, livestock wastewater of small livestock facilities, and rural sewage or forestry in rural areas without sewerage. These pollutants are less contributing to pollution and rely on natural treatment.

In other words, nonpoint sources are also referred to as non-specific sources, cotton sources, mobile sources, or other water sources. Unlike point sources that have specific discharge paths, nonpoint sources are often unspecified, such as urban road drainage or agricultural drainage. Refers to a place or area that generates nonpoint pollutants through an emission pathway.

Aquaculture aquaculture facilities, golf course facilities, transportation equipment, maintenance or junkyard facilities, concentrated aquatic products simple processing facilities, photograph processing facilities, etc., which have been renamed from `` specific facilities '' to `` other water pollution sources '' under the Water Quality Preservation Act; This includes other facilities such as product yards, product yards, and land quality change areas.

The double opening and closing plates 20 and 30 block the drain pipe P during rainfall, and guide the initial rainwater to fall into the initial excellent discharge port H, and open the drain pipe P when the rainfall increases.

To this end, the double opening and closing plate (20, 30) is composed of a shield 20 for selectively blocking the drain pipe (P), and the initial excellent discharge unit 30 for selectively opening the initial excellent discharge port (H). .

The shield 20 is connected to the rotating shaft 40, and is provided in a plate shape as shown, it is installed to cross the drain pipe (P) according to the rotation state. At this time, the length l2 of the shielding portion 20 is formed to be equal to the width l1 of the drainage pipe P, so that the initial excellent movement when the shielding portion 20 becomes orthogonal to the drainage pipe P. Can be completely prevented.

In addition, the drain pipe (P) is provided with a stopper (S). The stopper (S) is for limiting the rotation path of the double-opening plate (20, 30), exactly the shield 20 is to be rotated any more when it is orthogonal to the extension direction of the drain pipe (P) Do not let it.

On the other hand, Figure 3 shows another embodiment of the opening and closing assembly according to the present invention. As shown in FIG. 3, the length l 2 of the shielding part 20 of the double opening and closing plates 20 and 30 is longer than the width l 1 of the drain pipe P. Accordingly, one end of the shielding portion 20 is in contact with the side surface of the drain pipe (P) in the process of being rotated is the rotation path is limited.

That is, before the shielding portion 20 is in a state orthogonal to the longitudinal direction of the drain pipe P, the movement path is limited by contacting the inner surface of the drain pipe P during the rotation process. Accordingly, the drain pipe (P) does not have to be provided with a separate stopper (S). 3 illustrates a state in which one end of the shield 20 is in contact with the inner surface of the drain pipe P. As shown in FIG.

Next, referring to the discharge pipe 100 again with reference to Figure 1, the discharge pipe 100 is provided with a purification filter 150. The purification filter 150 is for filtering non-point contaminants from the initial excellent water falling into the discharge pipe 100, it is provided in the form of gabion (gabion).

In this case, the purification filter 150 is rotatably provided, so that the purification filter 150 may be naturally washed through the rotation of the purification filter 150. This will be described in detail with reference to FIG. 5.

At this time, the rotation of the purification filter 150 is made in conjunction with the opening and closing assembly (10). That is, the rotation of the double opening and closing plates 20 and 30 of the opening and closing assembly 10 is followed by the rotation of the purification filter 150 by the gear assembly 300 separately installed below the opening and closing assembly 10. .

More precisely, the gear assembly 300 is provided with a first gear 315 and a second gear 325 therein so as to rotate in the direction of rotation to change the purification filter 150, wherein the first gear ( 315 is connected to the rotary shaft 40 of the double opening and closing plates 20 and 30, and the second gear 325 is connected to the rotary shaft 155 of the purification filter 150, respectively.

In addition, the first gear 315 and the second gear 325 are each composed of a bevel gear to serve to convert the rotational direction in the direction orthogonal to each other. Reference numeral 310 denotes a connecting bar connected to the rotary shaft 40 of the double opening and closing plates 20 and 30, and reference numeral 320 denotes a connecting bar connected to the rotary shaft 155 of the purification filter 150, respectively.

In this case, the gear assembly 300 is configured to rotate the purification filter 150 by 180 ° when the double opening and closing plates 20 and 30 are completely rotated. That is, when the double opening and closing plates 20 and 30 are rotated 90 degrees (the embodiment of FIG. 2) or 45 degrees (the embodiment of FIG. 3) in the drain pipe P, the purification filter 150 rotates 180 degrees. Will be. This may be adjusted by the gear ratio of the first gear 315 and the second gear 325.

Meanwhile, a one-way bearing B is provided between the second gear 325 and the rotation shaft 155 of the purification filter 150. The one-way bearing (B) is to allow the purification filter 150 to rotate in only one direction. This is because the purification filter 150 is rotated only in one direction of rotation in the reciprocating operation of returning after the double-opening plates 20 and 30 are rotated, so that one surface of the purification filter 150 in one initial excellent discharge process The initial excellent discharge port (H) is faced, and in the next initial excellent discharge process, the other side faces the initial excellent discharge port (H).

And, through such a rotation, both sides of the purification filter 150, respectively, sequentially act as a filter in the initial excellent discharge process, at the same time the surface that is not used can be washed and washed by rainwater. Of course, the relatively large floating material seated on the upper surface of the purification filter 150 may fall during the rotation of the purification filter 150 may be cleaned.

On the other hand, the initial excellent discharge port (H) is provided with a replacement screen 500 to be detachable, the primary filtering the foreign matter contained in the initial excellent discharged through the initial excellent discharge port (H) from the drain pipe (P) I can make it.

The replacement screen 500 is provided in the form of a dense net, by filtering the foreign matter of a certain diameter or more contained in the initial excellent, it is possible to prevent the discharge pipe 100 is blocked. In particular, since the replacement screen 500 is fixed to the stopper 550 in a fixed state, the operator can be easily replaced.

Hereinafter, a process of separating and discharging the initial excellent water by using the opening and closing assembly for initial excellent separation according to the present invention will be described in detail with reference to the accompanying drawings.
