An apparatus for filtering grinding oil is provided to secure clean grinding oil by injecting the grinding oil of high pressure to sludge stuck to a surface of a filtering surface to remove the sludge. An apparatus for filtering grinding oil includes a body(110), a filtering tank(120), a water level detection sensor, a sprocket, a drive motor, a filtering screen(130), a sludge discharge hopper(140), an injection pipe(150), a sludge discharge pump(170), and a centrifugal separator. The filtering screen filters the grinding oil introduced through a grinding oil introduction opening. The centrifugal separator wastes the sludge by separating the sludge from the grinding oil to reuse the grinding oil. The sludge discharge hopper guides the sludge and the grinding oil dropping from the filtering screen to a sludge storage tank(122). The injection pipe has a plurality of injection nozzles(151) for dropping the sludge stuck to the surface of the filtering screen. The sludge discharge pump is connected to one side of the sludge storage tank to discharge the sludge and the grinding oil. The centrifugal separator is installed at one side of the sludge discharge pump to waste the sludge and reuse the grinding oil. |
