Exquisite cylinder type magnetic separator

The invention provides an exquisite cylinder type magnetic separator. The exquisite cylinder type magnetic separator comprises an outer cylindrical cylinder. A nylon end cover is arranged at one end of the outer cylinder, a detector switch is arranged on the nylon end cover, a magnetic core base is arranged at the other end of the outer cylinder, four magnetic cores are horizontally installed in an inner cavity of the outer cylinder, a stainless steel case is arranged on the outer sides of the magnetic cores, and a stroke air cylinder piston rod is connected with a disk filter net in the outer cylinder. After machining, cutting fluid of oiled scrap iron enters the cavity of the outer cylinder through a water inlet hosepipe, the magnetic cores attract the scrap iron onto the stainless steel case, the cutting fluid penetrates through the cavity through the disk filter net to leak to the water outlet side and is discharged out through the water outlet hosepipe to places where the cutting fluid needs to be circul
