【発明の詳細な説明】
本発明は液体あるいは気体などの流体中に混在
している磁性体粒子を磁気力によつて流体から分
離吸着する磁気分離装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic separation device that uses magnetic force to separate and adsorb magnetic particles mixed in a fluid such as a liquid or gas from the fluid.
従来、強磁性材から成るウール、エキスパンド
メタル、パンチングメタル、メツシユ等を磁気分
離素子として利用したこの種の磁気分離装置で
は、フイルタハウジング内に該磁気分離素子を充
てんし、直流磁界をハウジングの外部より印加し
て、素子の周辺に大きな磁気勾配を発生し、磁性
体粒子を素子の表面に直接吸着分離するものが一
般的であつた。 Conventionally, in this type of magnetic separation device that uses wool, expanded metal, punched metal, mesh, etc. made of ferromagnetic material as a magnetic separation element, the magnetic separation element is filled in the filter housing, and the DC magnetic field is transmitted to the outside of the housing. Generally, a large magnetic gradient is generated around the element by applying more force to the element, and magnetic particles are directly adsorbed and separated on the surface of the element.
しかし、上記の従来のものにあつては、直流磁
界の印加手段に永久磁石を用いる場合、素子に付
着堆積した磁性粒子を払い落とすには、該素子を
磁界空間から外部に移動させて、磁性粒子の素子
への磁気吸着力をなくす必要が生じる。また磁界
空間の外部に素子を移動しても、素子に残留磁化
が有る場合、磁気吸着力が完全に無くなるわけで
はないから、ブラシによるかき取りや水洗いや機
械振動によつても、堆積粒子を素子から全て除去
することは困難である。 However, in the conventional device described above, when a permanent magnet is used as a means for applying a DC magnetic field, in order to remove the magnetic particles that have adhered and accumulated on the element, the element must be moved outside from the magnetic field space and the magnetic particles must be removed. It becomes necessary to eliminate the magnetic attraction force of particles to the element. Furthermore, even if the element is moved outside the magnetic field space, if the element has residual magnetization, the magnetic attraction force will not be completely eliminated. It is difficult to remove all of it from the device.
同様に、直流磁界の印加手段に電磁石を用いる
場合には、励磁電流を切つて磁気分離素子に印加
された磁界を完全に無くしても素子に残留磁化が
有ると堆積粒子を完全に除去することは困難であ
る。 Similarly, when an electromagnet is used as a means for applying a DC magnetic field, even if the excitation current is turned off and the magnetic field applied to the magnetic separation element is completely eliminated, if there is residual magnetization in the element, it is difficult to completely remove the deposited particles. It is difficult.
本発明の磁気分離装置においては、磁性粒子を
磁気分離素子表面に直接吸着することなく、素子
として用いた表面に突起を有する強磁性平板ある
いは強磁性丸棒を取り囲んだ非磁性材から成る中
空板状体あるいは中空丸棒の表面に磁性粒子を吸
着し、該平板あるいは該丸棒を抜き出せば、該平
板あるいは該丸棒に残留磁化が有つても非磁性材
からなる中空体表面の磁性粒子に働く磁気吸着力
は完全に無くなつているため、堆積粒子の払い落
としは極めて容易になる。 In the magnetic separation device of the present invention, the magnetic particles are not directly adsorbed onto the surface of the magnetic separation element, and instead, a hollow plate made of a non-magnetic material surrounding a ferromagnetic flat plate or a ferromagnetic round bar having protrusions on the surface used as the element is used. If magnetic particles are adsorbed onto the surface of a hollow body made of a non-magnetic material, and the flat plate or round bar is extracted, even if the flat plate or round bar has residual magnetization, the magnetic particles on the surface of the hollow body made of non-magnetic material will be absorbed. Since the magnetic adsorption force is completely eliminated, it becomes extremely easy to brush off the accumulated particles.
以下、本発明の一実施例を図面によつて説明す

を払い落として回収する。 When capturing magnetic particles in a fluid, as shown in FIG.
A ferromagnetic flat plate 2 having a large number of protrusions on its surface is inserted, and the flat plate 2 is magnetized by a permanent magnet 3 as shown in FIG. In this state, as shown in Figure 3,
A fluid containing magnetic particles 5 is introduced from an intake port 7. The introduced fluid passes through the gap 8 of the hollow plate-like body 1 made of a non-magnetic material containing the ferromagnetic plate 2,
The magnetized ferromagnetic flat plate 2 is discharged from the discharge port 9, but due to the magnetic gradient generated on the surface of the non-magnetic flat plate 1, a magnetic force acts on the magnetic particles 4 in the fluid, forming a plate-like shape. It is attracted to the body surface and captured. On the other hand, the non-magnetic particles 6 in the fluid are not captured and exit from the outlet 9. FIG. 4 is an overall view of the magnetic separation device in a state where magnetic particles are captured. After capturing a certain amount of magnetic particles, the fluid supply is stopped and the ferromagnetic plate 2 is pulled out from the hollow plate-like body 1 as shown in FIG. 5 to reduce the magnetic gradient on the surface of the hollow plate-like body 1. In other words, the magnetic force acting on the magnetic particles is eliminated, and the accumulated particles are collected by scraping them with a brush or by brushing them off with backflow water, compressed air, or mechanical vibration.
従来の磁気分離装置においては、磁気分離素子
の表面に直接磁性粒子を吸着するため、素子への
印加磁界を無くしても、素子自体が残留磁化を有
する場合があり、捕捉粒子に働く磁気吸着力を完
全に無くすことができずに払い落とし効率が悪く
なる結果を招いた。 In conventional magnetic separation devices, magnetic particles are directly attracted to the surface of the magnetic separation element, so even if the magnetic field applied to the element is removed, the element itself may have residual magnetization, which increases the magnetic attraction force acting on the captured particles. It was not possible to completely eliminate the dust, resulting in poor brushing efficiency.
本発明によれば、捕捉面に付着した粒子に働く
磁気吸引力を、粒子を払い尊とす際には完全に無
くすことができるため、従来の磁気分離装置に比
較して極めて効率良く払い落としができる。 According to the present invention, the magnetic attraction force acting on the particles attached to the capture surface can be completely eliminated when removing the particles, so the particles can be removed more efficiently than conventional magnetic separation devices. I can do it.

強磁性平板２の代わりに突起付き丸棒１０を用い
た。 Another embodiment of the invention is shown in FIG. A hollow round bar 9 was used instead of the hollow plate-like body 1, and a round bar 10 with projections was used instead of the ferromagnetic flat plate 2 with projections.
