Definitions
- the present invention can increase the residence time of the liquid in the cylindrical body, thereby increasing the efficiency of removing magnetic foreign substances mixed into the liquid, and increasing the cleaning efficiency of the magnetic material. It is an object of the present invention to provide a method and an apparatus for removing magnetic foreign substances of liquid power, which can simultaneously increase the amount of cleaning liquid collected and reduce the amount of waste.
- a Compressed air generator (compressed air generating means).
- the transfer side magnetic separator (transfer member) 41 that can transfer to the transfer position and the magnetic gradient between the transfer side magnetic separator 41 when the magnetic foreign matter reaches the transfer position by the transfer side magnetic separator 41,
- a transfer-side magnetic separator (transfer member) 42 is provided for foreign matter to jump onto the outer peripheral surface of the transfer-side magnetic separator 41 and to be attracted thereto.
- a shutter 58 for supplying used cleaning liquid to the outer peripheral surface of the first cylindrical drum 45 is provided (FIG. 3). Further, on the outer peripheral surface of the first cylindrical drum 45, a plurality of ridge-pulling members 60 parallel to the drum axis are provided at equal intervals in a circumferential direction. Each pulling member 60 is made of stainless steel, and is fixed to the first cylindrical drum 45 by welding or the like. The pulling member 60 is similarly welded to the outer peripheral surface of the second cylindrical drum 48.
- waste oil (including chips) in the waste oil storage tank 22 guided by the slurry pump 14 is gradually supplied from below into the cylinder 11 through the waste oil pipe 23.
- the waste oil continuously moves upward in the cylinder 11.
- the chips contained in the waste oil are magnetically attached to a large number of magnetic spheres 12 that have been magnetized.
- the treated oil from which the chips have been removed is discharged from the upper end of the cylinder 11 to the outside through the treated oil discharge pipe 35.
- the third valve 26 and the fifth valve 31 are closed, and the pumping of the compressed air by the compressed air generator A is stopped.
- the residual liquid can be used as a treated oil.
- the residual liquid tends to contain a large amount of iron, etc., and in special cases, in order to minimize the incorporation of magnetic foreign substances, this residual liquid should not be used as used oil. It is preferable to return to the above and perform the magnetic separation again.
- a current of a predetermined magnitude is instantaneously passed through the exciting coil 13 to reversely excite and demagnetize.
- vibration is applied to the cylinder 11 by the vibrator 17 to agitate the magnetic spheres 12 in the cylinder 11.
- the second valve 24 and the fourth valve 28 are opened, the supply pump 16 is operated, and the cleaning liquid is supplied from the cleaning liquid storage tank 59 through the cleaning liquid supply pipe 30 into the cylinder 11.
- a plurality of injection pumps (not shown) may be operated to inject a part of the cleaning liquid into the cylinder 11 from the plurality of injection nozzles 20 arranged on the peripheral wall of the cylinder 11!
- the compressed air generator A is operated, and the cleaning liquid is sprayed together with compressed air of lkgZcm 2 or more through a pipe (not shown).
- the cleaning liquid injected from the injection nozzle 20 is a magnetic ball.
- the oil, including chips, that has penetrated evenly between the bodies 12 and adhered to the magnetic spheres 12 is dissolved and desorbed by the action of ultrasonic waves.
- the cleaning liquid that has flowed into the cylinder 11 from above pushes out chips and oil in the cylinder 11 to the outside of the lower part of the cylinder 11.
- the extruded used cleaning liquid is supplied to the shutter 58 of the transfer-side magnetic separator 41 through the cleaning liquid discharge pipe 25.
- the values in FIG. 6 indicate the respective gaps 46 between the first cylindrical drum 45 and the second cylindrical drum 48.
- the numerical value of the magnetic flux density measured at the measurement point, and the unit is Gauss.
- the coordinates are indicated by the alphabet D-M columns written at the top of the grid, which is divided vertically and horizontally, and 1-16 rows arranged vertically on the right.
- the magnetic flux density at point (M, 1) is 30 Gauss.
- the gap 46 between the two drums 45 and 48 may be 15-50 mm so as not to sandwich the pulling member 60.
- the chips move through the gap 46 most of the used cleaning liquid that has adhered to the surface of the chips is wiped off here, and only substantially the chips are adsorbed to the second cylindrical drum 48.
- the moving distance of the swarf is as large as 15-50 mm, and the effect of removing used cleaning liquid is great.
- the discharge of the liquid from the inside of the cylinder 11 and the discharge of the cleaning liquid after washing from the inside of the cylinder 11 are forcibly performed by the compressed air generated by the compressed air generator A.
- the time for discharging the liquid from the cylinder 11 and the cleaning liquid after the cleaning can be reduced.
- the magnetic spheres 12 are washed, the magnetic spheres 12 are washed while being vibrated with the vibration of the cylinder 11. Thereby, the chips attached to the magnetic sphere 12 can be effectively removed.
- the chips contained in the used cleaning liquid are attracted to the outer peripheral surface of the first cylindrical drum 45 by the magnetic force, and then, at the transfer position, are transferred to the transfer-side magnetic separator 41 at the transfer position. Due to the magnetic gradient with the selector 42, chips from the washed cleaning liquid jump to the outer peripheral surface of the second cylindrical drum 48 and are adsorbed. That is, the cleaning liquid remains on the outer peripheral surface of the first cylindrical drum 45, and only the chips having a small amount of the cleaning liquid adhere to the outer peripheral surface of the second cylindrical drum 48. As a result, the cleaning liquid later falls by its own weight into the cleaning liquid storage tank 59 from the outer peripheral surface of the first cylindrical drum 45 and is recovered, and the recovery amount is increased as compared with the conventional case.
- the waste collected by the scraper 70 is a chip with a small amount of cleaning liquid instead of a chip with a large amount of cleaning liquid as in the past, so that the amount of waste can be reduced. .
