Abstract

When the liquid is supplied to the inside of the cylinder from the lower side, the liquid stays in the cylinder, and the magnetic foreign matter is magnetically attracted to the magnetic ball. Only by supplying the cleaning liquid into the cylinder from the upper side, the magnetic foreign matter is discharged from the lower opening of the cylinder together with the cleaning liquid. At the transfer position, the magnetic foreign matter in the cleaning liquid is transferred from the cleaning liquid to the outer peripheral surface of the magnetic separator on the transfer side.

Description

technical field [0001] The present invention relates to a method and device for removing magnetic foreign matter from liquid, more specifically to a method and device for removing magnetic foreign matter mixed in liquid by using a magnetized magnetic body and removing magnetic foreign matter from liquid . Background technique [0002] Conventionally, Patent Document 1 is known as a method for removing magnetic foreign matter from a liquid. [0003] According to the removal method of Patent Document 1, first, a plurality of magnetic spheres are filled in the cylindrical body in which the excitation coil is wound on the outer peripheral surface. Next, waste oil or the like from a metal processing machine is supplied into the cylinder through the opening on the upper side, and then the exciting coil is energized to magnetize the magnetic balls. As a result, magnetic foreign matter such as cutting chips contained in waste oil or the like is attracted to the magnetic balls. ...
