<P>PROBLEM TO BE SOLVED: To efficiently take out fine magnetic material in waste liquid without using a filter aid. <P>SOLUTION: A stainless steel belt conveyer 2 is synchronized with an outer periphery of a magnet conveyer 3 attached with a magnet 33. Grinding waste liquid is dripped in water droplets, fog or thin water film state from a nozzle 11 on an ascending slope 24. As the water thickness is thin, whole water is exposed to a strong magnetic field. Thus, the even fine magnetic material is attracted and ascends the slope. The belt forms a downslope 25 ahead, the magnet 33 of the rear face of the belt gets away from the belt surface on the way, the magnetic field is reduced to separate and drop the attracted matter from the belt conveyer 2. Liquid and others separated from the ascending slope drop and are stored in a coolant tank 4, and only supernatant can be reused as clean liquid. Precipitate is passed through a transparent pipe connected to a pail can 55, and appropriate cleaning timing is visually known. By covering the upper face of the belt with a photocatalyst, the liquid thickness is reduced by its hydrophilicity to enhance the attraction effect. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
