It relates to a switchgear.

In general, water pollution sources are divided into point sources and nonpoint sources for the convenience of prevention and management. Point sources are pollutants that emit wastewater containing pollutants in sewer pipes or ditches at specific locations, such as sewage, wastewater treatment plants, power plants, waste mines, oil tanks, oil wells, etc. Say what you can. Non-point sources, on the other hand, emit pollutants from a wide area scattered here and there. Rainwater, which flows through deforestation areas, urban areas, construction sites, parking lots, roads, etc., is introduced into rivers and seas. It is a kind of pollution that occurs when it rains or when snow melts.

The pollution of water quality by these nonpoint sources is not evident in its severity, and it is difficult to predict the emission of pollutants, and it is difficult to efficiently deal with the concentration due to seasonal precipitation.

Therefore, it is efficient to install small-scale treatment facilities around the area where pollutants can be generated so that they can be treated at that time. Contaminants mixed in these non-point sources cannot be easily separated, so they cannot be treated in river or sea. It can get into and cause serious environmental pollution. As a method of purifying contaminants mixed in contaminants introduced from nonpoint source, a hydrocyclone separator is used to purify by centrifugal force according to the size and density of contaminants contained in the contaminant.

3 is a view showing a wastewater purification treatment apparatus 1000 provided with a fluid opening and closing device 200 according to an embodiment of the present invention, and FIG. 4 is a cross-sectional view taken along line III-III of FIG. First, the fluid opening and closing device 200 according to an embodiment of the present invention will be described with reference to FIGS. 3 and 4. As shown in Figures 3 and 4, the fluid opening and closing device 200 according to an embodiment of the present invention includes a housing 210, a bream member 220 and the outlet opening and closing member 230.

The housing 210 is formed with an inlet port 211 through which the contaminated liquid containing suspended matter flows in, and an outlet port 212 through which the contaminated liquid flows out.

The bure member 220 is height is adjusted by the buoyancy according to the amount of the contaminated liquid filled in the housing 210.

The outlet opening and closing member 230 is connected to the beret member 220, when the height of the beret member 220 is adjusted up and down, while moving to each other with the beret member 220 to open and close the outlet a (212). In addition, the outlet opening and closing member 230 may have a rubber baring 231 on one side corresponding to the outlet a 212, whereby the outlet opening and closing member 230 may more effectively block the outlet a 212.

On the other hand, as shown in Figure 4, the housing 210 has a bypass hole 213 for discharging the contaminated liquid in the housing 210 when the outlet opening and closing member 230 is blocking the outlet a (212) Can be further formed.

In addition, it may further include a connecting rod 260 for connecting the beret member 220 and the outlet opening and closing member 230, it may be connected to the beret member 220 and the outlet opening and closing member 230. That is, the bleeding member 220 and the outlet opening and closing member 230 are connected to the connecting rod 260, so that the bleeding member 220 and the outlet opening and closing member 230 may be raised and lowered together.

In addition, it may further include a guider 240 for guiding a path that the buckle member moves. The guider 240 may be coupled to the inside of the housing 210 and may have a tubular shape in which upper and lower portions surrounding the connecting rod 260 are open. Therefore, when the buckle member 220 floats and sinks due to buoyancy, the connecting rod 260 rises and falls vertically by riding the guider 240. Therefore, the outlet opening and closing member 230 connected together to the connecting rod 260 is to be able to accurately block the outlet a (212).

Meanwhile, the bypass pipe 270 is connected to the bypass hole 213 to directly discharge the contaminant in the housing 210 through the bypass hole 213.

As described above, the fluid opening and closing device 200 according to the present invention can be used as a device to limit the amount of fluid, such as water or oil is excessive, in particular, opening and closing the outlet by buoyancy using the fluid introduced Since it can be, it can be utilized as a non-powered switchgear which does not need to equip power supply facilities etc. separately.

4 and 5 will be described the operation of the fluid opening and closing device 200 according to an embodiment of the present invention, and the operation of the sewage purification treatment apparatus 1000 is installed.

First, referring to FIG. 4, a contaminant flowing from a non-point source is introduced into the housing 210 of the fluid opening and closing device 200 through an inlet port a 211. In general, the initial contaminant contains a relatively large amount of suspended solids. When the contaminant is filled up to the outlet a (212) of the housing 210, the chamber 110 of the pollutant purification apparatus 100 through the inlet b 111 of the pollutant purification apparatus 100 connected to the outlet a (212). The contaminant flows into). The contaminant introduced into the chamber 110 passes through the lower end of the shielding membrane 120 and then passes through the discharge hole 131 of the separator 130 and exits to the outlet b 112. At this time, since the area of the shielding membrane 120 is designed to be wider than the area of the discharge hole 131, and the lower end of the shielding membrane 120 is installed lower than the lower end of the discharge hole 131, the contamination flowing into the inlet b 111 is contaminated. The suspended solids mixed in the liquid have a lower specific gravity than the treatment liquid accumulated in the chamber 110, so that the flow is no longer blocked by the shielding membrane 120, so that the discharge hole 131 having a higher height than the lower end of the shielding membrane 120 is formed. Will not pass. In addition, the suspended matter which does not pass through the shielding film 120 and accumulated on the outside of the shielding film 120 in the chamber 110 may be collected to the outside through the manhole 140 formed on the ceiling side.

As shown in FIG. 5, more contaminant flows into the housing 210 of the fluid opening and closing device 200, and thus, more contaminant flows into the chamber 110 of the contaminant purification apparatus 100. When the water level inside the jersey housing 210 and the chamber 110 is increased, the bleeding member 220 is raised according to the water level, and the outlet opening and closing member 230 connected to the bleeding member 220 and the connecting rod 260 is also included. As it rises, the outlet opening and closing member 230 blocks the outlet a (212) when it exceeds a certain level. At this time, the outlet opening and closing member 230 is pressed by the water pressure caused by the contaminant in the housing 210, so that the blocking effect is further increased. In addition, when the water level inside the housing 210 becomes higher, the buckle member 220 is further raised accordingly, and the outlet opening / closing member 230 connected to the buckle member 220 becomes higher beyond the outlet a 212. The outlet a 212 can be opened again. Therefore, even if the water level rises in a state in which the outlet opening and closing member 230 blocks the outlet a (212), the guiding member 220 is guided to the connecting rod 260 connected to the guiding member 220 so as not to rise any more. It is preferable to set the height of the guider 240 so that the 240 can hold.

In addition, when the outlet opening and closing member 230 rises to a position to block the outlet a (212), the subsequent filling of the contaminated liquid can be discharged directly through the bypass pipe 270 connected to the bypass hole (213).

Non-point source is caused by the inflow of pollutants accumulated on the ground such as roads, construction sites, and parking lots into the drains along with rainwater. There is a feature not included. Therefore, even if the contaminant more than the throughput of the fluid switchgear 200 and the sewage treatment system 1000 in which the fluid switchgear is installed in consideration of the amount of contaminants in a specific region is discharged through the bypass pipe 270. It does not significantly affect water pollution. On the contrary, when more than the amount of pollutants flows into the pollutant purification apparatus 100, the existing floats which have been separated are flowed back, or due to the high flow rate, the floats are discharged through the discharge holes 131 and discharged to the outlet b 112 to flow into the rivers. It can flow in, which can seriously affect the water quality of the surrounding rivers. Therefore, such a situation can be prevented with the fluid opening and closing device 200.

As described above, the detailed description of the present invention has been made by the embodiments with reference to the accompanying drawings. However, since the above-described embodiments have only been described by way of example, the present invention is limited to the above embodiments. It should not be understood that the scope of the present invention is to be understood by the claims and equivalent concepts described below.

As described in detail above, the present invention has the following effects.

First, when the amount of the inflowing fluid is excessive, it is possible to open or block the inflow of the fluid with no force by using buoyancy. In addition, the blocked fluid can be discharged forcelessly through the bypass hole, thereby preventing backflow of the fluid.

Second, by installing a fluid opening and closing device in a pollutant purifying device that processes pollutant flowing from a nonpoint source, if the amount of pollutant that is relatively less contaminated by heavy rain or other factors increases, the pollutant is introduced into the pollutant purifying device. By blocking the discharge and by discharging the relatively less contaminated contaminants, it is possible to prevent the suspended matter separated from the contaminant purification apparatus from being swept away.
