Magnetic pipeline filter

The utility model discloses a magnetic pipeline filter, which is characterized in that a strong magnetic rod is inserted into a shell, a sealing cover is screwed at the top end of the shell, then a dirty solution is introduced into a dirty solution inlet, the dirty solution flows into a gap between the strong magnetic rod and the shell, iron powder in the dirty solution is adsorbed by the strong magnetic rod, and obtained purified water enters an inner cavity of the strong magnetic rod from a water inlet hole; finally, the purified water enters the purified water outlet from the water outlet hole and is discharged; the shell is transparent, so that whether the adsorption of the internal iron powder is saturated or not can be intuitively seen through the transparent shell; through the arrangement of a limiting plate and a limiting groove, the limiting plate is always inserted into the limiting groove, and the strong magnetic rod is prevented from inclining; and through the arrangement of the sealing ring, the
