Description
Technical field
The present invention relates to a kind of magnetic selection method and device.
Background technology
The existing technology utilizing magnetic field gradient to carry out fluid deferrization arranges soft magnetic medium in a magnetic field, then fluid is flowed through magnetizing mediums, utilize the ferromagnetic material in the fluid of the magnetizing mediums aspiration flow warp be magnetized, thus reach the object of deironing, the ability of ferromagnetic material is drawn in order to promote magnetized soft magnetic medium, the magnetic position of soft magnetic medium is protruded often, so that the magnetic force of soft magnetic medium all focuses on protruding parts, simultaneously, spacing between the protruding parts of shortening soft magnetic medium as much as possible, this kind of technology, although, effectively can remove the ferromagnetic material comprising weak magnetic in fluid, but, due to soft magnetic medium protruding parts between spacing smaller, after the amount of the ferromagnetic material drawn when protruding parts reaches and is coupled together two protruding parts, one defines magnet short-cut path, make not become magnetic field gradient between two protruding parts, thus reduce the magnetic force of protruding parts significantly, reduce magnetic attraction significantly, simultaneously, the ferromagnetic material be deposited between two protruding parts also seriously plugs the transit passage of fluid, now, even if soft magnetic medium is moved apart magnetic field, and the clean ferromagnetic material be attached on protruding parts, after moving apart magnetic field, ferromagnetic material is owing to being non-soft magnetic medium, therefore, also remain stronger magnetic force, in conjunction with the space between narrow and small protruding parts, give to clean and bring very large difficulty, adopt general cleaning means as vibration mode, water backwashing manner, aeration cleaning mode or these modes comprehensive, the ferromagnetic material be all not easy being attached on protruding parts is clean clean, moreover, limited by fluid properties, as fluid be solid powder time, cleaning means can only be the mode of vibrations and aeration cleaning, and these modes are for the number folded soft magnetic medium arranged layer by layer, cleaning effect can not meet the demands.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of can comprise weak magnetism magnetic material, simultaneously effectively in draw fluid, the magnetic separation fluid iron removal that can effectively clean soft magnetic medium again and device.
Magnetic separation fluid iron removal of the present invention realizes like this, comprise removing ferromagnetic material from fluid process, soft magnetic medium cleaning course, its special feature is that removing ferromagnetic material from fluid process the several layers of soft magnetic medium be made up of several soft magnetic medium is placed in magnetic field and vertical magnetic field magnetic direction, the part of the symmetry of the both sides in the cross section of every root soft magnetic medium is projection, spacing between two projection outermost end is greater than the spacing between the two ends at other positions in soft magnetic medium cross section, be arranged in parallel between adjacent two soft magnetic mediums of every layer, and protruding parts is oppositely arranged, the spacing between two adjacent two soft magnetic mediums is made to be minimum, then fluid is imported in soft magnetic medium, soft magnetic medium cleaning course stops importing fluid, soft magnetic medium is made to depart from the effect in magnetic field, then soft magnetic medium is rotated, the minimum two ends of the vertical range of the both sides in soft magnetic medium cross section are made to be positioned at the left and right sides, like this, expand the spacing between adjacent two soft magnetic mediums, then, the ferromagnetic material on clean soft magnetic medium.
Here, soft magnetic medium freely rotates to be arranged in fluid passage.Because soft magnetic medium is freely rotate in fluid passage, after entering magnetic field, soft magnetic medium is magnetized, the magnetic force of the soft magnetic medium after magnetization focuses on protuberance office, like this, under the effect of own magnetic force, soft magnetic medium rotates into naturally, the line of both sides projection is parallel with magnetic direction, makes the spacing between two adjacent two soft magnetic mediums be minimum; After leaving magnetic field, under cleaning action power (as vibrations, cleaning fluid impact) combines the acting in conjunction of the gravity of the ferromagnetic material of attachment, soft magnetic medium overturns, and makes the spacing between two adjacent two soft magnetic mediums become large.
Due to during except ferromagnetic material, spacing between adjacent two soft magnetic medium projections is little, effectively can draw the ferromagnetic material comprising weak magnetism magnetic material in the fluid through between adjacent two soft magnetic medium projections, therefore, except ferromagnetic material effect is very good, when clean soft magnetic medium, by rotating ferromagnetic material, one, the ferromagnetic material that the extruding force effectively can destroying the magnetic force remained on ferromagnetic material and the ferromagnetic material be blocked between adjacent two soft magnetic medium projections causes is close to soft magnetic medium projection and is not easy the generation of situation about cleaning, the ferromagnetic material squeezed between adjacent two soft magnetic medium projections is loosed off, and offset the suction of ferromagnetic material retained magnetic forces to soft magnetic medium projection by soft magnetic medium rotatory force, so that ferromagnetic material is by self gravitation and the extraneous vibration force applied, flush fluid (comprises gas, liquid) flushing ability from soft magnetic medium projection rinse clean, the spacing of adjacent two soft magnetic mediums expanded also is conducive to passing through of ferromagnetic material and flush fluid.
Here, the cross section of soft magnetic medium is square or approximating square or rhombus or near-rhombic or regular hexagon or approximate regular hexagon or oval or approximate ellipsoidal.
Magnetic separation type fluid iron removal device of the present invention realizes like this, comprise magnetic field, soft magnetic medium layer, soft magnetic medium cleaning mechanism that fluid passage, several layers of being arranged in fluid passage are made up of several soft magnetic medium, its special feature is that the part of the symmetry of the both sides in the cross section of every root soft magnetic medium is projection, spacing between two projection outermost end is greater than the spacing between the two ends at other positions in soft magnetic medium cross section, be arranged in parallel between adjacent two soft magnetic mediums of every layer, soft magnetic medium rotates and is arranged in fluid passage.
Here, soft magnetic medium freely rotates and is arranged in fluid passage or has the rotating drive mechanism driving every root soft magnetic medium to rotate in the arranged outside of fluid passage.
During work, all soft magnetic mediums are driven to rotate by rotating drive mechanism, the adjacent two soft magnetic medium protruding parts of every layer are oppositely arranged, the spacing between two adjacent two soft magnetic mediums is made to be minimum, then several layers of soft magnetic medium are placed in magnetic field, import fluid, the ferromagnetic material in the fluid flow through is removed by soft magnetic medium, after the amount of the ferromagnetic material on soft magnetic medium acquires a certain degree, several layers of soft magnetic medium layer are moved apart magnetic field, all soft magnetic mediums are driven to rotate by rotating drive mechanism, the minimum two ends of the vertical range of the both sides in soft magnetic medium cross section are made to be positioned at the left and right sides, then, by soft magnetic medium cleaning mechanism, ferromagnetic material is cleaned from soft magnetic medium.
Here, the cross section of soft magnetic medium is square or approximating square or rhombus or near-rhombic or regular hexagon or approximate regular hexagon or oval or approximate ellipsoidal.
Compared with the prior art the present invention, has and can comprise weak magnetism magnetic material, simultaneously effectively in draw fluid, again can effectively to the advantage that soft magnetic medium cleans.
