Description

Vertical non-powered rainwater filtration device { Non-powered rainwater filtration device }

The present invention relates to a non-powered rainwater filtering device, and more particularly, to filter various foreign substances included in rainwater flowing in during rain with a filter unit provided in a filter housing, some of which are discharged into a rainwater pipe, and the remaining part is guided to a rainwater storage tank, The filter housing is formed in a cylindrical shape with a hollow inside and installed in a vertical direction, the rainwater outlet connected to the rainwater pipe is formed at the bottom of the filter housing, and the storage outlet connected to the rainwater storage tank is formed on one side of the filter housing. It is discharged quickly through the rainwater pipe, and the rainwater moving to the rainwater storage tank is moved horizontally at an angle of 90 degrees to the falling direction of the rainwater, improving purification efficiency and significantly reducing maintenance costs by purifying rainwater without power. It relates to a vertical non-powered rainwater filtering device that does not include electronic devices in the filtering device and does not require frequent maintenance due to corrosion or damage.

In recent years, water shortage is being carefully predicted in Korea, and alternatives for securing and utilizing water more effectively are emerging as a very important issue.

As the pollution of water sources accelerates, the government designates and manages water source protection areas for the purpose of protecting water sources, and in order to preemptively respond to climate change and future water shortages, eco-friendly water resources that reuse water once used, that is, rainwater, In order to systematically support the promotion of reuse of sewage (sewage that is below the predetermined standard pollution level, eg, washbasin sewage, etc.), detailed guidelines for establishing a water reuse management plan and laws for promoting and supporting water reuse have been enacted and implemented.

In addition, the government enacted the Water Management Technology Development and Water Industry Promotion Act to reduce dependence on limited water resources and use them efficiently, introducing a resource energy device that reuses discarded water (domestic sewage, etc.) to promote green growth. is leading the practice. In other words, in order to promote the use of rainwater, rainwater utilization facilities are installed and operated when building sports complexes, gymnasiums, public offices, general buildings, etc., and it is recommended to reprocess domestic sewage and reuse it as various types of water.

However, in the case of Korea, it is never easy to efficiently collect rainwater because the four seasons are distinct and rainy weather is concentrated in summer. In addition, since an efficient structure for a rainwater filtration device for recycling rainwater has not been proposed, the reuse efficiency of rainwater or domestic sewage is very low.

As a conventional method for solving this problem, in preparation for water shortage in the dry season, a storage tank for storing rainwater is installed in schools, public facilities, and homes, and initial precipitation drainage is performed to improve the water quality of the rainwater stored in the storage tank. Rainwater is stored by installing a device, sediment discharge device, filtering device, and chlorine sterilization device, and the stored water is used as landscaping water or washing water.

However, since the above conventional rainwater filtration device uses rainwater stored in a rainwater storage tank through a horizontal gutter and a vertical downfall pipe through the water collection surface without a special treatment facility, sediment accumulation in the storage tank, generation and growth of microorganisms can easily occur. Due to water pollution and clogging of each pipe, it was difficult to manage efficiently, so there were many problems for consumers to use clean rainwater. For this reason, there is an urgent need for a rainwater filtration device capable of easily excluding a large amount of foreign substances contained in the initial rainwater in rainy weather and using it for other purposes by simply purifying the rainwater.

However, as shown in FIG. 1, the conventional filtering device 100 includes a plurality of electronic valves 400 for controlling the flow and purification of rainwater in the process of storing it in the rainwater storage tank 200 flowing into the rainwater pipe 300. and sensor 410, there is a problem that power is consumed to drive the solenoid valve 400 by receiving the signal of the sensor 410, which increases the maintenance cost, and the moisture Electronic devices are easily corroded or damaged, so there is a cumbersome problem that requires frequent maintenance.
