  Here, the outer diameter of the magnet case 20 of the main cylindrical magnet 31 is formed larger than the outer diameter of the magnet case 20 of the sub-cylindrical magnet 32. The main cylindrical magnet 31 has an outer diameter of 65 mm or more. In particular, in the present embodiment, the outer diameter of the magnet case 20 of the main cylindrical magnet 31 is 65.4 mm and the outer diameter of the magnet case 20 of the sub-cylindrical magnet is 23 mm. There is no limit.

The main cylindrical magnet 31 is provided on the lower surface of the fitting portion 16 so that the center portion of the bottom surface of the magnet case 20 of the main cylindrical magnet 31 coincides with the center portion of the fitting portion 16. Each sub-cylindrical magnet 32 is arranged on the lower surface of the fitting portion 16 on a concentric circle around the main cylindrical magnet 31 so that the direction in which the central axis extends is the same as that of the main cylindrical magnet 31. This makes it possible to efficiently attract and remove magnetic substances in the liquid, and to easily remove the magnetic substances adsorbed to the main cylindrical magnet 31 and the sub-cylindrical magnet 32. Here, in this embodiment, the sub cylindrical magnet 32 has an angle of a straight line connecting the center portion of each sub cylindrical magnet 32 and the center portion of the fitting portion 16 in a state where the lid portion 3 is viewed in plan.

In this case, the outer diameter of the magnet case 20 of the main cylindrical magnet 31 is formed larger than the outer diameter of the magnet case 20 of the sub-cylindrical magnet 32, and the outer diameter is formed to be 65 mm or more. Therefore, the main cylindrical magnet 31 has a large resistance against the flow of liquid flowing into the case 2, and the flow of liquid changes greatly.

At this time, the magnetic substance in the liquid is attracted by the magnetic force of the main cylindrical magnet 31 and the sub cylindrical magnet 32, and is attracted to the soft iron yoke 22 on the surface of the magnet case 20 of the main cylindrical magnet 31 and the sub cylindrical magnet 32. It will be adsorbed by the corresponding part.
As a result, the liquid in which no magnetic substance is mixed flows out to the outflow pipe 4 through the outflow path 12.

The magnetic substance adsorbed on the substrate can be removed.

Further, when the magnet filter 1 is used again, the main cylindrical magnet 31 and the sub-cylindrical magnet 32 extending below the fitting portion 16 are held inside the case 2 by holding the holding portion 17 of the lid portion 5. The case 2 and the lid portion 5 are combined by inserting the fitting portion 16 into the case 2 and the flange portion 10 of the case 2 and the lid body portion 15 of the lid portion 5 are fixed by a fixture.
