Description

[Detailed description of the invention] magnetic gravity filter field of invention The present invention relates to an apparatus for magnetic separation of substances, and more particularly to a magnetic gravity filter. .

Background of the invention Magnetic inserts filled with magnetized inserts used for evacuation of ferromagnetic particles from the fluid medium to be purified Various constructions of air gravity filters are known.

For example, a working chamber with a ferromagnetic insert of the filter layer and an electromagnetic chamber with an iron core of ferromagnetic plates. a stone, a pipe supplying the fluid medium to be purified, and a pipe discharging the purified fluid medium. A magnetic gravity filter (see Soviet patent A, 784.894) with be.

However, in this conventional magnetic gravity filter, the end portion of the electromagnet core near the working chamber fully magnetize the ferromagnetic insert in the longitudinal direction of each working chamber by Because it is not possible to purify the fluid medium to the desired level.

Further, in this filter, the iron core of the electromagnet is disposed outside the working chamber. Therefore The part of the magnetic flux generated by the electromagnet and distributed in the surrounding medium is the ferromagnetic insert. It affects the magnitude of the magnetic flux used for magnetization, and overall the effectiveness of the magnetic gravity filter. reduce the rate.

Other known magnetic gravity filters are connected to each other by connecting tubes and by magnetizing devices. two filtration chambers containing ferromagnetic inserts activated by the magnetic field generated by the Equipped with a pair of iron cores and a magnetic field generation source arranged facing each other, one of the filtration chambers is used for purification. The other filtration chamber contains a tube for discharging the purified medium. (See Soviet Patent^, No. 1,025.450).

In this magnetic gravity filter, the iron core of the magnetization device is placed outside the filtration chamber, and The sides of the core are adapted to contact the housing of the filtration chamber.

Since only the side of the electromagnet's core contacts the filtration chamber, the ferromagnetic insert can be inserted through that side. The amount of magnetic flux flowing inside the insert is sufficient to magnetize the entire insert to the required level. isn't it.

Furthermore, the surface of the iron core near the filtration chamber has a part of the surface of the end near the filtration chamber. Therefore, a portion of the magnetic flux generated by the electromagnet will be dispersed into the surrounding medium. , the magnitude of the magnetic flux used to magnetize the ferromagnetic insert is reduced, and the magnetization device and filter The efficiency of the entire system decreases.

In the above magnetic gravity filter, the part of the iron core near the source of the magnetic field is magnetically saturated. The part of the core remote from the source of the magnetic field has a magnetic pot in the length direction of the core. Since the magnitude of the magnetic field decreases, the magnetization is not sufficient, and therefore the magnetic field is removed from the source. The ferromagnetic inserts at the distal end of the remote core are not sufficiently magnetized and therefore the degree of purification is and reduce the efficiency of the filter.
