AUTOMATIC WASHING DEVICE OF MICRO FILTER SYSTEM

摘要

PURPOSE: An automatic washing device of a micro filter system is provided to continuously remove impurities from a micro filter by installing an air supply pipe for injecting high-pressure air into the micro filter. CONSTITUTION: An air supply pipe(40) includes an upper support unit(42) inserted into a support hole in a protecting pipe(20), and a lower support unit(48) fit into a support groove(72). The air supply pipe discharges air through air discharge holes(44), and separates impurities from a micro filter(50). An air discharge pipe(34) is formed at an upper flange(10), and discharges the air discharged from the air supply pipe. A first pressure sensor(84) is installed at a water supply pipe(82), and detects the pressure of introduced water. A second pressure sensor(18) is installed at a water discharge pipe(16), and detects the pressure of discharged water. A control unit detects the pressure difference of the first and second pressure sensors, and generates a control signal if the pressure difference is more than a reference value. An air supply unit receives the control signal, generates air, and supplies the air to the air supply pipe.
