沿って、所定の間隔で並列設置するのが望ましい。The ferromagnetic plate may have various shapes as long as it can be attached and fixed to the inner surface of the peripheral wall of the suction drum. However, as the strip plate, a predetermined shape is provided along the longitudinal direction of the suction drum. It is desirable to install them in parallel at intervals of.

することを可能にできる。In the oil separator of the present invention, when the suction drum is rotated in the oil tank, the ferromagnetic plate installed on the inner surface of the peripheral wall of the suction drum rotates while alternately facing the magnetizing device and the demagnetizing device. However, the ferromagnetic plate is in a magnetized state while facing the magnetizing device, and as a result, the iron powder in the oil is adsorbed by the magnetism appearing on the peripheral surface of the adsorption drum. On the other hand, when the ferromagnetic plate is demagnetized by facing the degaussing device, the attraction force for the iron powder adsorbed on the peripheral surface is lost and the ferromagnetic plate is desorbed. Therefore, if the iron powder is collected at the place where the ferromagnetic plate is demagnetized, it is possible to efficiently separate and remove even fine iron powder.

ことができる。The electromagnet 18, which is a degaussing device, causes a current as described later, that is, a current for demagnetizing the iron plate 6, to flow at the timing when the iron plate 6 and the magnetic pole of the iron core forming the electromagnet 18 face each other. Controlled. When the iron plate 6 is demagnetized by the electromagnet 18, the iron powder magnetized by the adsorption is also demagnetized at the same time. As a result, the adsorption force between the surface of the cylinder 5 and the iron powder is also lost, and the iron powder is dropped from the cylinder 5. be able to. Therefore, by collecting the iron powder that falls off at this position, the iron powder mixed in the oil can be separated and removed.

せることなく吸着できるようになる為である。FIG. 2 is a view for explaining the relationship between the permanent magnet 12 and the iron plate 6, which is shown in a developed state in the circumferential direction of the cylinder 5. As shown in (a) and (b) of the figure, the polarity of the permanent magnet 12 may be either in the diameter direction of the cylinder 5 (a) or in the circumferential direction of the cylinder 5 (b). Also in this case, the iron plate 6 can be magnetized. As shown in FIG. 2 (c), the iron plate 6 has a width (a) (b) rather than a width equal to the width of the permanent magnet 12.
As shown in FIG. 5, it is preferable to make the width narrower than that of the permanent magnet 12 so as to concentrate the magnetic flux. This is because a strong magnetic field is formed on the surface of the cylinder 5 and a strength distribution of the magnetic field is formed. In general, when magnetically adsorbing fine powder of iron powder, the magnetic saturation may hinder the adsorption, but by forming a strong and weak magnetic field distribution, the fine powder is magnetically saturated in a relatively weak magnetic field. This is because they can be adsorbed without causing them.

That is, the permanent magnet 12 is composed of a plurality of divided permanent magnets 12a, 12a in the axial direction of the cylinder 5 (a), and one permanent magnet over substantially the entire axial width of the cylinder. May be done. Depending on each case,
The electromagnet 18 constituting the degaussing device also includes a plurality of electromagnets 18.

の分離除去の効率が悪くなる為である。When demagnetizing the magnetizations of the iron plate 6 and the iron powder by the electromagnets 18 and 18a which are demagnetizing devices, it is necessary to prevent residual magnetism from occurring. This is because if magnetism remains on the iron plate 6 and the iron powder, the desorption of the iron powder becomes incomplete, and the efficiency of separation and removal from the oil deteriorates.
