Problems solved by technology

[0002] The existing technology of using magnetic field gradient to remove iron from fluid is to set a soft magnetic medium in a magnetic field, then flow the fluid through the magnetic medium, and use the magnetic medium magnetized by the magnetic field to absorb the ferromagnetic substances in the flowing fluid, thereby To achieve the purpose of iron removal, in order to improve the ability of the magnetized soft magnetic medium to absorb ferromagnetic substances, the magnetic attraction part of the soft magnetic medium is often protruding, so that the magnetic force of the soft magnetic medium is concentrated on the protruding part. At the same time, as much as possible Shorten the spacing between the protruding parts of the soft magnetic medium, although this technology can effectively remove ferromagnetic substances including weak magnetism in the fluid, but because the spacing between the protruding parts of the soft magnetic medium is relatively small, When the amount of ferromagnetic material absorbed by the protruding parts is enough to connect the two protruding parts, a magnetic short circuit is formed, so that no magnetic field gradient can be formed between the two

Example Embodiment

[0022] Example 1: Such as figure 1 As shown, the magnetic separation type fluid iron removing device of the present invention is realized in this way, including an electromagnetic or permanent magnetic field 1, a fluid channel made of non-magnetic material, and a plurality of layers arranged in the fluid channel 2 consisting of a number of soft magnetic fields. The soft magnetic medium layer 4 and the soft magnetic medium cleaning mechanism 5 formed by the medium 3 are special in that the symmetrical parts on both sides of the cross section of each soft magnetic medium 3 are the convex parts 6, and the two convex parts 6 are the outermost parts. The distance A between the ends is greater than the distance between the ends of other parts of the soft magnetic medium section. Two adjacent soft magnetic media 3 in each layer are arranged in parallel, and the soft magnetic medium 3 is arranged in the fluid channel 2 freely.

Example Embodiment

[0023] Example 2: Such as figure 2 As shown, this embodiment is based on the first embodiment, and a rotation driving mechanism 7 that drives each soft magnetic medium 3 to rotate is provided on the outside of the fluid channel 2.

[0024] Such as image 3 As shown, the first embodiment of the rotary drive mechanism 7 includes a gear 8 provided at the end of each soft magnetic medium 3, a drive mechanism 9 for driving the gear (including a drive gear 9a meshed with the gear 8 and an electric power 9b for driving the drive gear 9a ), the gears on each layer of soft magnetic medium 3 mesh with each other.

[0025] Such as Figure 4 As shown, the second embodiment of the rotating drive mechanism 7 includes a pendulum rod 10 connected to the end of each soft magnetic medium 3, a drive rod 11 that drives the pendulum rod 10 to swing, and a drive mechanism 12 (including an air cylinder 12a, The connecting rod 12b driven by the piston rod of the air cylinder 12a, and the connecting rod 1...

Abstract

The invention discloses a magnetic separation fluid iron removal method and device. The device comprises magnetic field, a fluid passage, a plurality of soft magnetism medium layers which are composed of a plurality of soft magnetism media and arranged in the fluid passage, and a soft magnetism medium cleaning mechanism, and is characterized in that symmetrical parts on the two sides of the section of each soft magnetism medium are convex parts; the space between the outermost ends of the two convex parts is greater than that between the two ends of other positions of the section of the soft magnetism medium; two adjacent soft magnetism media of each layer are arranged in parallel; the soft magnetism medium is rotationally arranged in the fluid passage. Compared with the prior art, the device has the advantage that the device can not only effectively absorb weak magnetic ferromagnetic substance in the fluid, but also effectively clean the soft magnetism medium at the same time.
