WATER FILTRATION EQUIPMENT POSSIBLE FILTERING AND BACK WASHING

摘要

PURPOSE: A water filtering apparatus with a filtering function and a backwashing function is provided to save energy and efficiently implement filtration by simply filtering feed water without a separate power supplying unit. CONSTITUTION: A water filtering apparatus includes a water bath(100), a filtering unit(200), a filtered water discharging pipe(300). A cylindrical upper rotor and a cylindrical lower rotor are separately arranged in the water bath, and a gap between the rotors is constantly kept. A filter(220) caterpillarly rotates by being installed between the rotors. A blocking member(230) blocks both parts of the filter. A space for filtered water is arranged in the filter. A rotor driving unit(250) for driving the upper rotor is installed at the upper rotor. One end part of the filtered water discharging pipe penetrates through the blocking member, and another end part of the filtered water discharging pipe penetrates through the water bath.
