コイルである。 FIG. 1 is a longitudinal sectional view of a magnetic separation device according to the present invention, in which a supply port 2 for a liquid to be treated is provided at one port of a frame 1 of the device, and a discharge port 3 is provided at the other port. There is. Non-magnetic porous plates 4 and 5 are fixedly arranged in the frame adjacent to the supply port 2 and the discharge port 3, and the above-mentioned amorphous plate A thin strip or tape 6 made of a high quality metal magnetic material
Many books are posted. Note that 7 is a coil for generating magnetism.

プ６の一端を固定してある。テープの他端は、同
様に、同様の多孔板５の内面に固定されている。 FIG. 2 is a perspective view showing the perforated plate 4 and tape 6 when the frame is cylindrical. One end of the tape 6 is fixed to the inner surface of the perforated plate 4, which is made of a plate made of Teflon, for example, with many holes. It has been done. The other end of the tape is similarly fixed to the inner surface of a similar perforated plate 5.
枠体１の大きさが、断面積1.8×2.0cm2で高さ5.0
cmの角柱状とし、テープ６として、幅250μm、厚
み20μmを用い、上述と同様にして、枠体内の充
填率2.0％になるように、等間隔で配置した。 The size of frame 1 is 1.8 x 2.0 cm 2 in cross-sectional area and 5.0 in height.
The tapes 6 were made into a prismatic shape with a width of 250 μm and a thickness of 20 μm, and were arranged at equal intervals in the same manner as described above so that the filling rate in the frame was 2.0%.
この枠体内に、供給口より、平均粒径0.19μm
の酸化鉄粉未を含む水溶液を２／分の割合で流
入させたところ、酸化鉄粉のテープへの吸着率は
約98％であつた。なお、印加磁界は約70Oeとし
た。 Inside this frame, from the supply port, the average particle size is 0.19μm.
When an aqueous solution containing no iron oxide powder was flowed in at a rate of 2/min, the adsorption rate of iron oxide powder to the tape was about 98%. Note that the applied magnetic field was approximately 70 Oe.
吸着率は処理前の水溶液に含まれる酸化鉄濃度
をW1、処理済の水に含まれる酸化鉄の濃度をW2
とし、
W1−W2／W1×100％
で表わされる。 The adsorption rate is defined as the concentration of iron oxide in the aqueous solution before treatment, W1 , and the concentration of iron oxide in the treated water, W2.
It is expressed as W 1 −W 2 /W 1 ×100%.
この結果、この種の磁気分離装置における印加
磁界としては70Oeというきわめて小さな磁界
（直流）でありながら、非常に高い分離能力を示
すことがわかる。 As a result, it can be seen that this type of magnetic separation device exhibits extremely high separation ability even though the applied magnetic field is extremely small (direct current) of 70 Oe.

極端に大となつていることによるものと思われ
る。 The reason why such a high separation ability is obtained is not only because it is an amorphous magnetic alloy, but also because the ribbon has a large adsorption area compared to its cross-sectional area, and because the ribbon is porous. This seems to be due to the fact that the interior of the hole acts as an adsorption surface, making the adsorption area extremely large.

等種々の方法が採用できることがわかつた。 In addition, various methods can be used to remove the adsorbed oxidized particles, such as demagnetizing the tape (this can be done using the coil 7), washing with forced water flow, mechanical vibration, ultrasonic vibration, etc. I understand.

With a composition of B 12 , the pore size is approximately 200 μm or less,
Magnetic properties are saturation magnetic flux density 10(K)G, coercive force
It was 0.04Oe.

面に固定されるか、第３図のようにしても良い。 In the above embodiment, the tape 6 is arranged so as to extend in the length direction along the flow direction of the processing liquid, but the tape 6 is arranged so that its length direction is perpendicular to the flow direction. However, in this case, the tape should be arranged so that its surface is parallel to the flow, and therefore the thickness direction is perpendicular to the flow. In this case as well, the first
The same effect as in the case of Fig. 2 was obtained. In this case, both ends of the tape may be fixed to the inner surface of the frame 1, or may be arranged as shown in FIG. 3.

The surface of the tape 6 is made perpendicular to the surface of the element 9. It is preferable to arrange a large number of such elements 9 in a stacked manner in the frame of the separation device (FIG. 1). In this case, if the upper and lower adjacent elements 9 are shifted by 90 degrees, the separation efficiency can be improved.

特徴を備えているものである。 As described above, the present invention uses an elongated amorphous magnetic alloy ribbon tape having multiple pores as a magnetic separation element, and its structure is such that in order to reduce the flow resistance of the processing liquid on the surface of the alloy ribbon tape, By arranging it parallel to the flow direction and parallel to the lines of magnetic force of the applied magnetic field so that it is easily magnetized, it not only has excellent adsorption ability in a low applied magnetic field, but also has low flow resistance due to the material, which prevents clogging. It has features that are extremely effective industrially, such as the fact that the operating time of the device can be extended because the increase in flow resistance of the liquid is small.
又一方、合金薄帯テープを平行状態を維持しつ

為に、粒子分離（吸着）後の磁気分離素子の取出

利点である。 On the other hand, since the alloy thin strip tape is maintained in a parallel state and is supported at both ends by a support and arranged in an orderly manner, it is easier to take out the magnetic separation element after particle separation (adsorption), and to clean and restore it. This is also an advantage of the present invention.
