Definitions
- the present invention relates to a screen for an electromagnetic separator that magnetically deposits iron powder, which is disposed in an electromagnetic separator that magnetizes and separates and removes iron powder in powder.
- Patent Document 1 In order to remove iron powder in powders in the fields of food, chemistry, medicine, etc., as an electromagnetic separator, a screen made of magnetic material is stacked in multiple layers in a cylinder placed in an electromagnet, and an opening at the top of the cylinder A method is known in which the iron powder in the powder supplied from is magnetically attached to a magnetized screen and separated (Patent Document 1).
- FIG. 4 shows an example of an electromagnetic separator using a conventional screen.
- a plurality of screens 22 made of a magnetic material are incorporated in multiple layers in a hollow portion of a cylindrical body 21 whose upper and lower ends are open.
- the projecting edges 23 project from and above the cylindrical body 21 at a required interval, surround the outer periphery of the cylindrical body 21 between the projecting edges 23, and hold the small gap between the electromagnets 24 in the spring 25.
- a vibrator 26 is attached to the lower part of the cylindrical body 21.
- each screen 22 in the cylindrical body is made of a magnetic material and the electromagnet. Since it is located within the magnetic field of 24, it is magnetized. Therefore, if powder is introduced from the upper end opening of the cylindrical body 21, the powder falls while passing through each screen 22 from above while being stirred in the cylindrical body by the action of vibration. During this time, the iron powder remains adsorbed by the magnetized screens 22, and the separated powder is led out from the lower end opening of the cylindrical body 21.
- FIG. 5 is a plan view showing an example of a conventional screen.
- Linear grades 28 made of a magnetic material are arranged in a saw-like pattern at intervals and fixed to a support member 29, and an annular through portion 30 through which an operating rod passes is formed in the center.
- the opening between the grades of the screen 22 is generally in the range of 5 mm to 20 mm.
- the linear grade is formed in a sawtooth shape, so the area where iron powder is magnetized is small, and there is a gap in the outer periphery of the screen.
- the recovery rate of the iron powder is low because the grade becomes thick to increase the magnetic flux density and the number of screens to be multilayered in the cylindrical body is reduced.
- the present invention provides an electromagnetic separator for separating iron powder in powder, increasing the area on which the iron powder is magnetized, increasing the number of screens, and passing the powder without being magnetized on the outer periphery of the screen.
- the present invention provides a screen for an electromagnetic separator capable of reducing the body and improving the recovery rate of iron powder.
- the present invention relates to an electromagnetic material made of a magnetic material that is held in multiple layers in a vertical direction in a cylinder disposed at the center of an electromagnet of an electromagnetic separator and magnetically irons iron powder in powder supplied from an opening at the top of the cylinder.
- an annular penetrating portion through which a holding rod for holding the screen passes is formed at the center of the electromagnetic separator screen, a ring frame is formed on the outside, and a gap is formed in the ring frame toward the penetrating portion.
- a spirally wound spiral plate a corrugated corrugated plate is disposed in the gap between the spiral plates, and corrugated valleys and peaks are fixed to the spiral plate.
- the ring frame and the annular through-hole have the same height, and the height of the spiral plate and the corrugated plate is smaller than that of the ring frame.
- the screen for an electromagnetic separator according to the present invention is formed in a honeycomb shape by a spiral plate and a corrugated plate, so that the magnetic adhesion area of the iron powder is increased, and in addition, the outer periphery of the screen is made up of ring frames. Since they overlap, the amount of powder passing from the outer periphery is greatly reduced, and the iron powder recovery rate can be improved.
- the powder diffuses into the space formed between the screens for the electromagnetic separators stacked one above the other. By doing so, the amount of powder passing straight through the screen can be reduced, so that the iron powder recovery rate can be increased.
- FIG. 1 is a schematic diagram showing a state where a screen for an electromagnetic separator according to the present invention is set in an electromagnetic separator.
- FIG. It is the schematic which shows the conventional electromagnetic separator only for powder. It is a schematic diagram which shows the conventional screen.
- an electromagnetic separator screen (hereinafter referred to as “screen”) 1 is made of a magnetic material. Any magnetic material may be used as long as it is magnetized, but ferritic stainless steel having corrosion resistance and strength is suitable.
- a ring frame 2 is formed by winding a stainless steel band around the outside of the screen 1.
- the outer diameter of the ring frame 2 is, for example, about 30 cm.
- an annular through portion 3 is formed through which a holding rod (FIG. 3) for holding the screen 1 passes.
- a spiral plate 4 is formed which is wound spirally at an interval with one point of the ring frame 2 as a start point (or end point) and an annular penetrating portion 3 as an end point (or start point).
- a continuous corrugated corrugated plate 5 is disposed in the gap between the spiral plates 4, and valleys and peaks of the corrugated plate 5 are fixed to the spiral plate 4 by spot welding.
- a large number of holes are formed in a honeycomb shape by the spiral plate 4 and the corrugated plate 5, and the size of the holes is selected according to the particle size, fluidity, and other characteristics of the powder.
- the ring frame 2 and the penetrating part 3 are set to the same height.
- the spiral plate 4 and the corrugated plate 5 have the same height, but are lower than the ring frame 2 and the penetrating portion 3, and when the screen 1 is overlapped, a space is formed between the upper and lower screens for the powder to diffuse.
- the ring frame 2 and the penetrating portion 3 are about 6 mm
- the spiral plate 4 and the corrugated plate 5 are about 5 mm.
- the conventional slat-like screen was about 23 mm and 20 sheets were stacked
- the screen of this example was about 6 mm in height and 75 sheets could be stacked, and the iron powder recovery rate was improves.
- FIG. 3 shows a state in which the screen 1 of the present invention is set in an electromagnetic separator. Similar to the electromagnetic separator shown in FIG. 4, the magnetic material is formed in the hollow portion of the cylinder 6 whose upper and lower ends are opened. A plurality of screens 1 are held in multiple layers by holding rods 7 in the vertical direction. The cylinder 6 is disposed at the center of the electromagnet 8, and a vibrator 9 is attached to the lower part of the cylinder 6.
- the product outlet 10 and the iron powder outlet 11 are connected to the lower part of the cylinder 6.
- the product discharge port 10 and the iron powder discharge port 11 are switched by rotating a damper 13 with a cylinder 12.
- the powder containing iron powder supplied from the upper part of the cylinder 6 is magnetically attached to the screen 1 magnetized by the electromagnets 8 stacked in multiple layers.
- the product from which the iron powder has been removed passes through the screen 1 and is then discharged from the product discharge port 10 by the damper 13.
- the damper 13 is switched to the iron powder discharge port 11, the electromagnet 8 is turned off, the screen 1 is demagnetized, and the iron powder adhering to the screen 1 is vibrated by the vibration of the vibrator 9. Remove. If necessary, the screen 1 is taken out with the holding rod 7 and cleaned to remove iron powder. The cleaned screen 1 is again inserted into the cylinder 6 and the iron powder separation operation is started.
- Test Example An iron recovery rate obtained by testing a sample A in which the particle size of the powder and the magnetic material are different from each other and a sample B having a particle size smaller than that of the sample A using a conventional sword-like screen and the screen of the present invention is shown.
