BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention introduces a treatment fluid into a strong and uniform magnetic field space generated by a magnetic unit fixed in an apparatus for magnetic treatment, thereby coagulating and precipitating the treatment fluid. The present invention relates to a magnetic fluid treatment device capable of efficiently removing substances.

2. Description of the Related Art In a conventional fluid magnetic processing apparatus, one or a plurality of permanent magnets are arranged in a non-magnetic tube, and the tube is sealed in a ferromagnetic outer tube. Disclosed is a method of magnetically treating a fluid flowing through a gap of a magnetic field by stopping and causing a treatment fluid passing through the apparatus to emit magnetic field lines. In this case, a ferromagnetic material made of a mesh wire is arranged on both sides of the permanent magnet. (Patent Fair 6-19
In such a conventional fluid magnetic processing apparatus, the magnetic flux density in the flow path of the processing fluid generated between the ferromagnetic bodies composed of the permanent magnet of 2,000 gauss and the mesh wire is high. The invention maintained at.

Further, a plurality of magnets are arranged so as to repel each other, a spacer of a ferromagnetic material is sandwiched to form a bar magnet, and the bar magnet is held so as to be positioned at the center of the tube.
Generated from a ring magnet by arranging fluid magnetic processing equipment with connecting tools at both ends of the pipe to facilitate connection with external equipment and internal cleaning, and magnetic needles in the flow path of the flow pipe. There is disclosed a magnetic processing apparatus that guides the magnetic field lines to the center of the flow path to homogenize the magnetic field in the flow path. (JP-A-7-8
09, JP-A-7-96173), an invention is disclosed in which a strong magnetic field is obtained by using a cylindrical inner magnetic pole body portion arranged in the flow path and narrowing the width of the gap between them. (Japanese Patent Publication No. 7-106352)

[0004]

According to the prior art,
As described above, a permanent magnet or a mesh wire is arranged in the flow path of the processing fluid, and a method of maintaining the magnetic flux density in the flow path at a high level or a needle-shaped body is arranged in the flow path to generate a uniform magnetic field. The invention discloses that the inner magnetic pole body is formed into a cylindrical shape and the width of the gap is narrowed to set a strong magnetic field.
However, in the method of arranging the permanent magnet in the container, the disclosure of the fixing method is unclear, and even if the magnetic flux in the central part of the channel can be maintained at a high level, it is necessary to generate a uniform magnetic field in the channel. I have a problem.

A bar magnet is provided in the casing of a non-magnetic material,
Even if a strong magnetic field can be generated by the number of spacers constituting the bar magnet, there is a problem in the effect of generating an important uniform magnetic field because the magnetic processing is efficiently operated. Further, in the structure of the magnetic processing device that guides the magnetic force lines to the center of the flow pipe via the magnetic body of the needle-shaped body, there is a possibility that the gap between the magnetic units is narrowed and the action of generating a strong magnetic field may be inconvenient. Since these magnetic field units are themselves fixed to the device, in order to improve the magnetic treatment effect by cleaning and removing the agglomerates adsorbed on these magnetic substances, the magnetic substance units are replaced instead of the magnetic substances themselves. Had to be replaced.

In the invention in which the inner magnetic pole body is formed in a cylindrical shape and the width of the gap is narrowed to set a strong magnetic field, the processing fluid flowing through the gap is determined by the shape and structure of the cylindrical magnetic pole body forming the main member. May interfere with each other and the flow velocity of the fluid may decrease, and if the gap between the magnetic pole bodies is further narrowed in order to further increase the magnetic field strength and further improve the fluid processing efficiency, the design and material costs will be high. Therefore, the economics associated with its implementation have not been emphasized enough.
