MAGNETIC SEPARATION APPARATUS AND WATER PURIFICATION EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide a magnetic separation apparatus that stabilizes magnetic separation properties by preventing the clogging of an aqueduct due to the build-up of a magnetic aggregate to the inner wall of a water conductive pipe and by accomplishing a cost reduction due to a small-diameter part of the water conductive pipe.

SOLUTION: The magnetic separation apparatus is provided with a coreless solenoid type magnet 105 at the surrounding of the water conductive pipe 301 to conduct a water from the lower part of the water to be treated containing the magnetic aggregate in which a pollutant and magnetic powder are condensed, a rotary disc type magnetic filter case 103 equipped with a matrix group to adsorb the magnetic aggregate in the water to be treated supplied from the water conductive pipe 301 at the upper part of the coreless solenoid type magnet 105 and a washing means 111 to wash the matrix group which is adsorbed by the magnetic aggregate. The water conductive pipe 301 has the small-diameter pipe 301a located within the coreless solenoid type magnet 105 and an expanded pipe 301b expanding to the water conductive part side of the rotary disc type magnetic filter case 103 from the small-diameter pipe 301a.
