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っ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.

が一般的であった。Conventionally, wool made of ferromagnetic materials, extracted band metal,
In this type of magnetic separation device that uses punching metal, mesh, etc. as a magnetic separation element, the filter housing is filled with the magnetic separation element, and a DC magnetic field is applied from outside the housing to create a large magnetic field around the element. It was common to generate a gradient to directly adsorb and separate magnetic particles onto the surface of the element.

や機械振動によっても、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 above-mentioned conventional devices, when a permanent magnet is used as a means for applying a DC magnetic field, the device must be moved outside from the magnetic field space in order to remove the magnetic particles that have adhered and accumulated on the device. Therefore, it becomes necessary to eliminate the magnetic attraction force of magnetic particles to the element.Furthermore, even if the element is moved outside the magnetic field space,
If there is residual magnetization in the element, the magnetic attraction force will not be completely eliminated, so scraping it off with a brush or washing it with water (・
It is difficult to remove all the deposited particles from the device even by mechanical vibration.

完全に除去することは困難である。8 Similarly, if 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 removed, residual magnetization in the element may cause the accumulation of particles. is difficult to completely remove.

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, but instead a ferromagnetic flat plate having protrusions on the surface used as an element or a hollow plate made of non-magnetic strips surrounding a ferromagnetic round holly is used as an element. If magnetic particles are attracted to the surface of a shaped body or a hollow round bar and the flat plate or round bar is extracted, the flat plate is found (・ means the surface of the hollow body made of non-magnetic material even if the round bar has residual magnetization. Since the magnetic adsorption force acting on the magnetic particles 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って説明する。An embodiment of the present invention will be described below with reference to the drawings.

に吸い付けられて捕捉される。When capturing magnetic particles in a fluid, a ferromagnetic flat plate 2 having many protrusions on the surface is inserted into a hollow plate-like body 1 made of a non-magnetic material as shown in Fig. 2, as shown in Fig. 2. The flat plate 2 is magnetized by the permanent magnet 3. In this state, as shown in FIG. 3, a fluid containing magnetic particles 5 is introduced from the intake lower part. The introduced fluid passes through a gap portion 8 of a hollow plate-like body 10 made of a non-magnetic material containing a ferromagnetic plate 2,
The magnetized ferromagnetic flat plate 2 generates a magnetic gradient on the surface of the non-magnetic flat plate 1, which causes a magnetic force to act on the magnetic particles 4 in the fluid, causing a magnetic force to be applied to the surface of the plate-like body. be attracted and captured.
一方、流体中の非磁性粒子６は捕捉されること１工く、
排出口９から出て（・く、第４図は磁性粒子を捕捉する
状態にある磁気分離装置の全体図である。On the other hand, the non-magnetic particles 6 in the fluid are difficult to capture,
FIG. 4 is an overall view of the magnetic separation device in a state where magnetic particles are captured after exiting from the discharge port 9.
一定量の磁性粒子を捕捉した後は、流体の供給を停止さ

した粒子を払い落として回収する。After capturing a certain amount of magnetic particles, the fluid supply is stopped, and as shown in FIG. ,
In other words, the magnetic force acting on the magnetic particles is eliminated, and the accumulated particles are collected by scraping with a brush, backwashing water, compressed air, or mechanical vibration.
従来の磁気分離装置においては、磁気分離装置の表面に

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
（・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 device, so even if the magnetic field applied to the device is removed, the device itself may have residual magnetization, and the magnetic adsorption force acting on the captured particles It was not possible to completely eliminate this, resulting in a decrease in 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

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. You can pay it off.
