Description

Drainage Reverse Flow Preventing and Bad Smell Blocking Device

The present invention is installed in the sewage and rainwater drainage which is one of the general household sewage or urban infrastructure, and the odor blocking and designed to exert a smooth drainage function while effectively preventing the discharge of sewage odors or sewage flowing back through the sewers and The present invention relates to a sewage backflow prevention device.

Sink connection pipes installed in kitchens of general households mainly use corrugated pipes because they reduce noise during drainage and facilitate the installation of sewer pipes. However, since various kitchen food residues easily accumulate and remain on the inner wall of the corrugated pipe used for sewage pipes, odors are generated and diverge into the room, causing odors to vibrate in the living room connected to the kitchen and the kitchen.

In order to prevent the emission of odor generated from the sink drain, a separate sink drain cap is normally used to seal the drain when the sink is not in use. However, due to the inherent function of the sink, the use of sink drain plugs is cumbersome and brings inconvenience to kitchen life.

In addition, the wastewater discharged in the factory area is a major culprit that pollutes the living environment of residents due to the generation of harmful gases or very bad smell.

On the other hand, low-rise houses or buildings with sewers or drains installed underground are likely to be flooded during heavy rain or rainy season. If you look at the causes of flooding of houses or buildings, it may be due to structural defects such as buildings, but most of the low pressure of sewers and drains in low areas is low, so that sewage or rainwater flows backwards in low water sewers.

Therefore, various kinds of drainage and backflow prevention devices are installed in the basement drainage of low-rise houses or buildings in preparation for the backflow of sewage or the backflow of rainwater.

However, these devices are designed to be inclined to only one of the drainage function and the backflow prevention function, so that both the backflow prevention function and the drainage function are not sufficiently satisfied.

In particular, inadequate or neglected drainage and backflow management in case of rainy season floods and heavy rains in areas where urban planning has been made along the riverside, the entire city can be flooded, resulting in enormous casualties and property damage.

An object of the present invention is to provide a odor blocking device that can smoothly drain domestic sewage and wastewater while completely blocking the bad smell or various harmful gases generated from the sewer or factory area sewer.

Another object of the present invention is to provide a sewage backflow blocker that can completely block backflow of sewage or rainwater indoors through the underground drainage of low-rise houses or buildings.

Another object of the present invention is to drain the rainwater collected from the heavy rain and rainy season smoothly toward the river, and also to prevent the river from flowing back along the rainwater drainage and flooding the entire city by increasing the water level through the city. To provide a sewage backflow blocker that can be.

When the opening and closing hemisphere 300 is pushed down to the lower side, the weight tube 440 and the rack tube 450 in the lower side are dragged by the forward rotation of the two pinion gears 430 and 430 'of the driving unit 400. Ascending, while operating member 420 is lowered.

When the opening and closing hemisphere 300 is moved downward while maintaining the driving state of the driving unit 400, the rounded contact of the ring-shaped locking ring 110 formed on the inner side of the upper hemisphere surface of the opening and closing hemisphere 300 and the housing 100 is provided. The inner diameter of the housing 100 is opened by moving to the lower side of the locking ring 110 in contact with the base 111 to close the sewer, that is, the inner diameter of the housing 100, to open the inner diameter of the housing 100. Come in to the side and get out of the drain.

When all of the sewage flows out in this way, the pressure held on the opening / closing hemisphere 300 disappears. However, since the gravity acts on the weight tube 440 of the driving unit 400 that has been raised in this state, the weight tube 440 is As a result, the rack tube 450 moving integrally with the weight tube 440 is lowered while the two pinion gears 430 and 430 'are reversed, thereby actuating the rack member 420. ) Is raised, the upper end of the rising member 420, that is, the cylinder 422 pushes the trap 340 of the opening and closing hemisphere 300. That is, when the weight tube 440 of the driving unit 400 is lowered, the pinion gears 430 and 430 'are reversely rotated, and thus the operating member 420 is raised and the opening and closing hemisphere 300 is raised accordingly. It rises until it catches the locking ring 110 of 100). Therefore, the upper surface of the opening hemisphere 300 is in close contact with the rounding contact 111 of the locking ring 110 formed in the housing 100 to close the inner diameter of the housing 100.

In addition, when the opening and closing hemisphere 300 completely blocks the inner diameter of the housing 100, if there is a reverse flow such as sewage, the housing 100 is brought into close contact with the locking ring 110 of the housing 100. No reverse flow occurs.

And, since the weight of the discharged sewage is significantly larger than the weight of the driving unit 400 is increased when the operation of the opening and closing hemisphere 300 is lowered, the lowering speed of the opening and closing hemisphere 300 is made of a very fast operation, As the discharged water is almost discharged, as the residual amount of the sewage to be discharged gradually decreases, the weight 440 of the driving unit 400 acts to increase the opening and closing hemisphere 300, thereby opening and closing the hemisphere 300. The ascending movement of is made slowly.

If the odor blocking and sewage backflow prevention device according to the present invention having the configuration and action as described above is installed in a sewer or a menhole hole, sewage or rainwater flows into the sewer, so that the sewer and manhole holes are completely blocked. Since the odor emitted is completely blocked, the odor generated in the sewers such as summer will be blocked and provide a comfortable environment.If the device of the present system is installed in the sewer formed in the sink of the home, the effect is extremely creepy.

In particular, when the device according to the present invention is installed in the factory's menhole or sewer, it prevents the leakage and scattering of harmful gas generated from the waste water, and thus the device according to the present invention will be called an environmentally friendly device. The sewage backflow prevention device is a device that contributes to a sanitary and comfortable environment because it completely seals the sewer as described above, thereby preventing the outflow of mosquitoes or other insects or other flammable gas inhabiting the sewer.

In addition, the odor blocking and sewage backflow prevention device of the present case has high water pressure, such as sewage flowing to the sewer due to rain or other reasons, so that even if a backflow occurs, the opening of the sewer, that is, the housing of the present case ( Since the inner diameter of 100) is completely sealed, there is no risk of backflow.

Therefore, the device of the present invention, when installed in the manhole hole of the lowland (방지 地帶) prevents the rainwater backflow generated through the manhole hole during the rainy season or heavy rains can prevent the flooding of roads or houses or delay the flooding by that much It works.

In addition, as described above, the ascending operation of the opening / closing hemisphere 300 in the present case at the time of discharge of sewage is performed at low speed, so that the sewage discharged is completely discharged, so that the sewer is occluded and there is no residual sewage.
