Magnetic strainer
First Claim
1. A magnetic strainer disposed on a line of a pipe to filter foreign matters contained in the pipe, comprising:
- a branch pipe (100) having an inlet (101) and an outlet (102) formed on both ends thereof and a filter insertion hole (103) formed unitarily on the center thereof;
a filter member (200) inserted into the filter insertion hole (103) in a longitudinal direction thereof and having a magnet part (230) adapted to collect conductors; and
a cap (300) screw-fastened to the filter insertion hole (103) of the branch pipe (100),wherein the filter member (200) comprises;
a filtering screen (210) whose one end is lockedly supported against a circular locking projection (104) formed in the middle portion of the interior of the branch pipe (100) and whose other end is lockedly and fixedly supported against a circular supporting projection (301) formed along the inner edge periphery of the cap (300);
a magnet case (220) disposed accommodatedly inside the filtering screen (210) and having an upper magnet case (221) and a lower magnet case (222) separably coupled to each other;
the magnet part (230) disposed inside the internal space of the magnet case (220) and having an upper magnet (231) and a lower magnet (232) arranged with repulsive forces in such a manner as to come into contact with the top and bottom ends of the internal space of the magnet case (220) to collect the conductors on the surface of the magnet case (220);
shield steel plates (240) coupled to the underside surfaces of the upper magnet (231) and the lower magnet (232); and
ascending and descending means (250 or 250′
) coupled retractably to a coupling hole (302) formed at the center of the bottom surface of the cap (300) and shaft-coupled to the magnet part (230) or the magnet case (220) in such a manner as to allow the upper magnet (231) coming into close contact with the top end of the magnet case (220) to be descended,whereby at the time of cleaning, the ascending and descending means (250 or 250′
) is descended to allow the upper magnet (231) to be descended, and an amount of magnetic force transferred to the conductors collected on the top end surface of the magnet case (220) is reduced, so that the conductors collected on the top end surface of the magnet case (220) are removed.

Abstract
The present invention relates to a magnetic strainer that is configured to have a cap disposed in a filter insertion hole formed on the center of a branch pipe having an inlet and an outlet coupled to a pipe and to have upper and lower magnets arranged with repulsive forces, while placing a repulsive space therebetween, in such a manner as to be accommodated in both ends of a magnet case in a longitudinal direction of the magnet case to allow conductors in impurities to be easily collected to the inside of a filtering screen disposed between the filter insertion hole and the cap to filter the impurities, so that if ascending and descending means disposed under the magnet case operates, the upper magnet is descended to the repulsive space to easily remove the conductors collected on the top end surface of the magnet case.
