[0003]

[Problems to be solved by the invention]

 Claim 1 according to the present invention relates to a magnetic separator provided with an inlet straightening plate 34 for efficiently collecting magnetic sludge and preventing overflow of the coolant from the magnetic separator side plate 33. Floating debris, such as fine iron powder, carbon generated by grinding of cast iron, and fine debris entangled with the adhesive of the grinding wheel, are generated between the straightening plate 34 and the coolant inlet 12. The flow rate of the coolant in the magnetic separator becomes slow due to the rectification action of the coolant by the rectifying plate 34, and the coolant between the non-magnetic rotary cylinder 16 and the rectifying plate 34 Floating debris 32 that floats above the liquid surface and remains in the magnetic separator can be discharged to the outside of the magnetic separator. And to provide a magnetic cell Palais motor having a rectifying plate that employs a novel shape.

[0004]

The magnetic separator according to claim 1 is capable of avoiding overflow of the coolant from the magnetic separator side plate when the coolant flows in and efficiently collecting magnetic sludge. At the same time, a coolant inlet straightening plate having a slot for discharging the floating debris accumulated in the magnetic separator from the magnetic separator is provided.

[Embodiment of the invention]

 The magnetic separator provided with the coolant inlet straightening plate having a slot according to the present embodiment is a magnetic separator for filtering the coolant discharged from an industrial machine such as a grinder. The magnetic separator for filtering the coolant discharged from an industrial machine such as a grinder is used for efficiently collecting the magnetic sludge as described above, and the coolant from the magnetic separator side plate when the coolant flows in. It has been demanded that the floating debris floating on the coolant in the magnetic separator be discharged to the outside of the magnetic separator while preventing overflow of the magnetic separator. Hereinafter, typical embodiments of the present invention will be described with reference to the drawings. However, the dimensions, shapes, materials, relative positions, etc. of the components described in this example are not intended to limit the scope of the invention to these unless otherwise specified. , Are merely illustrative examples. As can be seen from FIGS. 1 and 2, the magnetic separator main body 11 includes an inlet 12 and an outlet 13 in the magnetic separator provided with the coolant inlet flow straightening plate having a slot according to the present embodiment. There is a flow straightening plate 14 with slots on the entire surface of the inlet 12. A rotating cylinder 16 which is concentric with the magnet drum 15 and whose inner wall rotates with a small gap between the magnet drum 15 and the inlet / outlet is accommodated in the magnetic separator main body 11 together with the magnet drum 15. The rotary shaft 17 of the rotary cylinder 16 extends to the outside of the magnetic separator main body 11, where a sprocket wheel 18 is mounted, and is mounted on a bracket 19 protruding from the magnetic separator main body 11. A chain 22 is hung between the small sprocket wheel 21 on the motor 20 side with the speed reducer and the sprocket wheel 18 to rotate the rotary cylinder 16 in the direction of the arrow shown in the figure. A semi-cylindrical bottom plate 23 coaxial with the rotating cylinder 16 is provided below the rotating cylinder 16, and forms a flow path 24 with the rotating cylinder 16. In the upper part of the rotary cylinder 16, a squeezing roller 25 is penetrated so as to be able to freely move up and down in the radial direction of the rotary cylinder 16 by respective screw rods 26 set up from the left and right sides of the magnetic separator main body 11. The outer periphery of the rotating cylinder 16 is constantly pressed by a coil spring 28 for each screw rod 26, and the axis of the roller shaft 30 is predetermined with respect to the radial direction of the rotating cylinder 16. Can be extended within the range. In addition, a scraping plate 29 is for scraping off sludge adhering to the outer periphery of the squeezing roller shaft 30, and the sludge peeling plate 31 on the outlet 13 side presses the outer periphery of the rotary cylinder 16 to separate the adsorbed sludge. ing.

In the magnetic separator having such a structure, when the magnetic chips or the coolant containing the abrasive grains and the floating chips discharged from the industrial machine such as the grinding machine is allowed to flow from the inlet 12, The flow of the coolant at the time of inflow of the coolant is suppressed by the slotted flow straightening plate 14 installed in front of the inflow port 12. At the same time as efficient collection of sludge becomes possible, the floating debris 32, which had previously floated on the coolant in the magnetic separator as described above, was removed from the magnetic flux generated by the slots provided in the current plate. Coolant from the coolant inlet 12 on the upper surface of the coolant to the non-magnetic rotating cylinder 16 in the separator Can be discharged to the outside of the magnetic separator. In addition, the device of the present invention is not limited to the embodiment described above and shown in the drawings as described above. It can be appropriately changed without departing from the gist, such as the structure.

[0007]

[Effect of the invention]

 According to the magnetic separator having a slot in the coolant inlet straightening plate of the present invention, the coolant flows from the coolant inlet on the upper surface of the coolant in the magnetic separator generated by the slot to the non-magnetic rotating cylinder, Floating debris, which had been accumulated on the upper surface of the coolant inside the magnetic separator, can now be discharged to the outside of the magnetic separator, so that contamination in the magnetic separator caused by the floating debris can be avoided. The effect also avoids problems such as overflow of the coolant from the magnetic separator due to clogging of the flow path in the magnetic separator, early deterioration of each component constituting the magnetic separator, and deterioration of the coolant. With regard to coolant for industrial machines such as grinders that are used repeatedly, by maintaining cleanliness and extending the life, the performance of industrial machines such as grinders can be maintained and overall operation costs can be reduced. is there.
