[Embodiment of the invention]

 The magnetic separator according to the present embodiment, which is provided with a roller in contact with the upper outer periphery of the squeezing rubber roller and presses the squeezing rubber roller, is a magnetic separator for filtering the coolant discharged from an industrial machine such as a grinder. is there. The magnetic separator that filters the coolant discharged from an industrial machine such as a grinder, as described above, uses the coolant contained in the sludge adsorbed on the outer periphery of the non-magnetic rotary cylinder as described above. There has been a demand for sufficient dewatering or deoiling treatment with a rubber roller for squeezing. Hereinafter, typical embodiments of the present invention will be described with reference to the drawings. However, the dimensions, shapes, materials, relative positions, and the like of the components described in this example are not intended to limit the scope of the present invention only to them unless otherwise specified. , Is merely an illustration. As can be understood from FIGS. 1, 2 and 3, the magnetic separator according to the present embodiment, which is provided with a roller in contact with the upper periphery of the squeezing rubber roller and pressing the squeezing rubber roller, is mounted on the magnetic separator base 11. Has an inlet 12 and an outlet 13, and a flow straightening plate 14 is provided in front 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 base 11 together with the magnet drum 15. The rotating shaft 17 of the rotating cylinder 16 extends to the outside of the magnetic separator base 11, where a sprocket wheel 18 is attached, and is attached to a bracket 19 which is protruded from the magnetic separator base 11. A chain 22 is hung between the small sprocket wheel 21 on the side of the motor 20 with a 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 rotary cylinder 16 is provided below the rotary cylinder 16 to form a flow path 24 between the rotary cylinder 16 and the bottom plate 23. On the upper part of the rotary cylinder 16, a rubber roller 25 for squeezing is provided with a rubber roller bracket 39 fitted with two screw rods 26 erected from the left and right sides of the magnetic separator base 11 so as to be able to freely move up and down. The outer circumference of the rotating cylinder 16 is constantly pressed by a coil spring 28 for each screw rod 26. A roller holder 34 is attached to the rubber roller brackets 39 at the left and right sides of the rubber roller 25 for squeezing via two columns 33, respectively, and the roller holder 34 is freely moved up and down near the center thereof. Two left and right roller bolts 35 fitted into the roller retainer 34 so as to be movable are attached to two right and left roller brackets 37. The rollers 36 are attached to the right and left two roller brackets 37 in contact with the squeezing rubber roller 25 so that the roller 36 is rotatable along with the rotation of the squeezing rubber roller 25. In order to make the pressing force of the rubber roller 25 for squeezing by the roller 36 variable, the right and left two screws each having an adjustable deflection amount are attached to the two left and right roller bolts 35 fitted into the roller holder 34. A pulling 38 is fitted. The pressing mechanism 40 of the squeezing rubber roller 25 attached to the roller retainer 34 has one place when the length of the squeezing rubber roller 25 is more than 200 mm and 500 mm or less, and about two places when the length of the squeezing rubber roller 25 is more than 500 mm and 1500 mm or less. However, the present invention is not limited to this range, and may be appropriately adjusted as needed according to the amount of the sludge adsorbed on the rotating cylinder 16 which is concentric with the magnet drum 15 and whose inner wall rotates with a small gap from the magnet drum 15. It can be changed. The length of the roller 36 is arbitrarily set each time according to the sludge amount, the length of the squeezing rubber roller 25, and the like. The scraping plate 29 is for scraping off sludge adhering to the outer periphery of the squeezing rubber roller 25, and the sludge peeling plate 31 on the outlet 13 side presses the outer periphery of the rotating cylinder 16 to remove the adsorbed sludge to the rotating cylinder 16. Peeling is occurring. The sludge separated from the rotating cylinder 16 by the sludge separation plate 31 is discharged to the outside of the magnetic separator along the receiving plate 32. In addition, the device of the present invention is not limited to the embodiment described above and shown in the drawings, but can be appropriately changed without departing from the scope of the invention.

[Effect of the invention]

 By providing the pressing mechanism in the vicinity of the center of the squeezing rubber roller of the present invention, it is possible to avoid the bending of the squeezing rubber roller, which is particularly likely to occur when the squeezing rubber roller is long, for example. The coolant by a rubber roller for drawing, such as a center portion of a rubber roller for drawing the coolant contained in the sludge adsorbed on the rotating cylinder having a built-in drum, or a portion where the sludge is concentrated and adsorbed on the rotating cylinder. Can be avoided. In addition to this, in addition to the above, damage to the squeezing rubber roller caused by the bending of the squeezing rubber roller, other early deterioration of the components constituting the magnetic separator, and the need for frequent By maintaining the cleanliness and extending the life of coolant for industrial machines such as grinders that are used repeatedly, the performance of industrial machines such as grinders can be improved. And can contribute to a reduction in operating costs as a whole.
