Abstract

PURPOSE:To facilitate separation and lifting by inducing different magnetic poles in laminated steel boards through magnetism provided from a core and passing through the casing and the magnetic pole face, thereby releasing face contact between the laminated steel boards. CONSTITUTION:In a DC magnetic separator 10, a core 14 and an exciting coil 16 are arranged in a non-ferrous casing 12 while a synthetic resin layer 16a is arranged around the coil 16 and the coil 16 is secured therein. An insulating member 18 and a heat radiation member 19 made of epoxy series synthetic resin are arranged in the gap between the core 14 and the coil 16, and a separation core 20 is provided to the core 14 in the casing 12. An insulating member 18 is provided in the rear of the core 14 and the coil 16 in the casing 12, then a back plate 22 is provided integrally. Since the back plate 22 is provided in the rear of the casing 12 while facing with a magnetic pole face 13, magnetism is reflected effectively in the direction of the steel board and passes through the magnetic pole face to induce different magnetic poles in the laminated steel boards 50 thus attracting the steel board 50 and separating the steel board sequentially and automatically.

Description

[Detailed description of the invention] [Industrial use bone! Ff] The present invention relates to a DC electromagnetic separation device, and more particularly to a DC electromagnetic separation device that automatically separates a large number of laminated thin steel plates or other metal materials one after another using the attractive force of an electromagnet. It is difficult to separate a large number of laminated thin steel plates, and especially when oil is attached to the thin steel plates, separation is difficult and dangerous.

Therefore, a thin steel plate separation device using a permanent magnet has been proposed.

[Problems to be Solved by the Invention-1 However, if the permanent magnet is used to properly attract the ends of the required thin steel plate 50 as shown in the figure, however, in normal cases or the size of the steel plate, In some countries, like in the 8th country, the thin steel plate 50 is attracted to the permanent magnet 60 of the device,
In order to separate this, it is necessary to forcefully separate it, so Jj
It is dangerous and may become unusable.

Then, when carrying in and out of steel plates, peripheral equipment such as evacuation devices and conveyors should be installed, and separate storage areas for steel plates should be installed (・There is no need to hang up. For this reason, a device using electromagnets; t has also been proposed. However, the electromagnetic adsorption force is weak, the imitation is complicated, and if it is laminated in a complicated manner, it is almost impossible to put it into practical use.

1 Techniques for solving problems (I-like means 1) This invention (
``, +iir, the gist of which is to eliminate the drawbacks mentioned above, is to provide gauging made of non-ferrous metal, provided within the non-ferrous metal casing, excited by an iron core and an excitation coil,
1) In the space between the separating iron core placed on the magnetic pole surface of the casing, the surrounding layer provided around the excitation two fills, and the 4th layer in the 1st gear sink, A metal hack plate I- is provided on the gaging opposite to the direction of the magnetic pole to reflect magnetism and form a magnetic circuit. It consists of a kite made of non-ferrous metal that is perpendicular to the IR structure: the upper edge of the magnetic pole surface is the sloped side, one of the iron cores is the N pole, the other is the S pole, and the casing is made from the iron core. This is a DC electromagnetic separation device that separates the laminated steel plates by inducing magnetic poles of different types in the steel plates stacked facing each other with the magnetism passing through the magnetic pole surfaces.

However, this invention has a magnetic separation buoyancy similar to that of a permanent magnet, and is capable of automatically separating not only thin steel plates but also other small metal materials. It provides:

1. Effect] The DC electromagnetic component gll) device having the above-mentioned structure is laminated with a thin &50 g
One of the! Place ijX on both sides.

Incidentally, the upper part of the laminated thin plate 50 is provided with rifting as required.
A magnet l-40 is installed (') 1. A metal back plate 22 is provided on the back side of the square iron metal casing 12, facing the magnetic pole 1*i13, so that the magnetism is directed directly toward the magnetic pole surface JJ. The magnetism that has passed through the magnetic pole direction is effectively reflected on the steel plate, and induces different polarities in each of the steel plates 50 stacked facing each other, thereby attracting the steel plate 50 as shown in Fig. 1.6.
This allows automatic separation in sequence.

1 Example] DC electromagnetic component R [device 10 includes non-ferrous metal casing 12
The iron core 14 and the excitation: 1 coil 16 are arranged in the exciter, and in the gap between the iron core 14 and the excitation: 2 coil 16, an insulating material 18 and a heat dissipation material 19 such as epoxy synthetic resin are arranged. Place G
:L, An iron core 20 for separating rice cakes is installed on the iron core 14 in the non-ferrous metal casing 12.

After installing the iron core 14, excitation coil 16, and insulating material +8a in the rear part of the casing 12, attach the metal hack play 1 and 2.
2 will be set up and integrated.

In claim (2), on the surface of the casing 12,
A plurality of non-ferrous metal guides 24 having a required width and thickness corresponding to the separating iron core 20 are vertically arranged;
A portion thereof is made to protrude from the surface of the casing 12, that is, from the magnetic pole face 13, so that the steel plate 50 can be guided smoothly.

In claim (3), the upper edge of the magnetic pole face 13 of the casing 12? 3a and the upper edge 24a of the kite 24 are inclined surfaces.

Then, the power supply cord 26 is connected to a required location on the side surface of the non-ferrous metal casing 12.9 I-effect] The metal back plate 22 effectively reflects the magnetism to the front, that is, the work surface, through the magnetic pole surface 13. However, different types of polarity are also induced in the thin steel plate 50. The edges 40a of the stacked thin steel plates 40 are induced by the same i as shown in FIG. The second injury becomes easier.

The voltage adjustment makes it extremely easy to separate and float various types of steel plates.

6-(2) A plurality of non-ferrous metal guides 24 are vertically protruded from the magnetic pole surface 13 in an I-bar row to reduce the coefficient of friction with the surface of the lever, and furthermore, the upper edge 13a and the ends of the guides 1 to 24 are Since the edge 2Aa is an inclined surface, there is no chance of damage caused by contact with a corner of the main body.

(3) In the permanent magnet type separator 60, depending on the size of the steel plate 50, the steel plate 50 is attracted to its main body, making it unusable, but the DC electromagnetic separator 10 according to the present invention
In this case, this problem can be solved by voltage adjustment as described above.

Since it becomes possible to separate and float steel plates and members of any shape according to their shape, weight, etc., this leads to the simplification of industrial equipment.

(5) Lifting When this DC electromagnetic dispensing device 10 is installed in equipment such as the magnet 40, there is no need for conventional evacuation equipment when loading and unloading the steel plate 50, and the equipment is simplified and the operation is easier. It becomes easier.

(6) Also, if this DC electromagnetic separation device 10 is not energized,
There is no danger in attracting anything else.

(7) Through automatic control, even if various steel plates 50 are laminated in a complicated manner, high productivity of the entire device can be obtained due to the common separation ability.

(8) As mentioned above, since various steel plates can be laminated in a complicated manner, there is no need for storage areas for different plate thicknesses, and the steel plate storage space can be used effectively.

(9) Productivity is increased by interlocking with the operation of equipment such as the lifting magnet 40.
