Description

Smart Auto Backwash Filtering System / Water Filter The present invention relates to a smart automatic filter cleaning precision filtration system, and more specifically, to a smart automatic filter cleaning precision filtration system that filters foreign substances mixed in raw water supplied through a drain pipe and removes foreign substances accumulated during the filtration process without interrupting the supply of raw water. Generally, water used in homes or industrial sites is supplied through pipes after purification and filtration treatment; therefore, various filtration devices are currently being used to remove foreign substances such as rust, scale, and suspended solids that accumulate during the supply process due to filtration treatment and pipe aging. In addition, filtration systems primarily utilize cartridge-based methods that involve replacing filters and meshes, or cleaning methods, which incur maintenance costs and cause problems with unstable water supply due to water cutoffs during maintenance. Therefore, a backwashing filtration device that removes foreign substances without interrupting operation has been proposed and is widely applied to water supply and industrial facilities. A "rotary upward-flow water quality filtration device" has been presented as such prior art. The prior art relates to an improved rotary upward-flow water quality filtration device that can effectively remove settled sludge or deposited sediment present in a closed body of water such as a pond, and allows for stable drainage of filtered contaminants. In other words, the prior art has a configuration in which a filter membrane is installed inside a housing, a 'spraying means' is provided to draw back a portion of the filtered water through a circulation pump and spray it toward the filter membrane, and contaminants on the surface of the filter membrane are removed by rotating this spraying means using a geared motor. However, the prior art requires additional circulation pumps and complex piping lines, which increases the overall volume and necessitates installation space; furthermore, there are issues with manufacturing costs and difficult maintenance due to the complex piping structure. In addition, there are limitations in removing fine particles and accumulated foreign substances between the filter mesh when water is sprayed, and there is a problem where the removed foreign substances float inside and reattach, reducing backwashing efficiency. In addition, prolonged use while submerged in water leads to malfunctions caused by corrosion and the accumulation of foreign matter, resulting in difficult maintenance.
