Description
Technical field:
The present invention relates to a kind of magnetic selection method and device.
Background technology:
The existing technology of utilizing magnetic field gradient to carry out fluid deferrization is, in Yi magnetic field, soft magnetic medium is set, then the magnetizing mediums of fluid being flowed through, ferromagnetic material in the fluid of the magnetizing mediums aspiration flow warp that utilization has been magnetized, thereby reach the object of deironing, in order to promote magnetized soft magnetic medium, draw the ability of ferromagnetic material, protrude often at the magnetic position of soft magnetic medium, so that all focusing on, the magnetic force of soft magnetic medium protrudes position, simultaneously, shorten as much as possible the spacing of the protuberance interdigit of soft magnetic medium, this kind of technology, although, can effectively remove the ferromagnetic material that comprises weak magnetic in fluid, but, because the spacing of the protuberance interdigit of soft magnetic medium is smaller, after protruding the amount of the ferromagnetic material of drawing at position and reaching two protrusion positions are coupled together, one has formed magnet short-cut path, make two protuberance interdigits not become magnetic field gradient, thereby reduced significantly the magnetic force that protrudes position, weakened significantly magnetic attraction, simultaneously, the ferromagnetic material that is deposited in two protuberance interdigits has also seriously stopped up the transit passage of fluid, now, even soft magnetic medium is moved apart to magnetic field, and the clean ferromagnetic material protruding on position that is attached to, owing to moving apart behind magnetic field, ferromagnetic material is owing to being non-soft magnetic medium, therefore, also remain more intense magnetic force, space in conjunction with narrow and small protuberance interdigit, give the clean very large difficulty of bringing, adopt general cleaning means as vibration mode, water backwashing manner, aeration cleaning mode or these modes comprehensive, all be not easy being attached to the ferromagnetic material protruding on position clean clean, moreover, limited by fluid properties, while being solid powder as fluid, cleaning means can only be the mode of vibrations and aeration cleaning, and these modes fold for number the soft magnetic medium arranging 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 and comprises weak magnetism magnetic material, simultaneously in a kind of draw fluid effectively, can effectively to soft magnetic medium, carry out clean magnetic separation type fluid deferrization method and device again.
Magnetic separation type fluid deferrization method of the present invention is to realize 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 is to make the several layers of soft magnetic medium consisting of several soft magnetic mediums be placed in magnetic field and vertical magnetic field magnetic direction, the symmetrical part of the both sides in the cross section of every 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, between adjacent two soft magnetic mediums of every layer, be arranged in parallel, and protruding position is oppositely arranged, making the spacing between two adjacent two soft magnetic mediums is minimum, then fluid is imported in soft magnetic medium, soft magnetic medium cleaning course is to stop importing fluid, make soft magnetic medium depart from the effect in magnetic field, then rotate soft magnetic medium, make the two ends of vertical range minimum of the both sides in soft magnetic medium cross section be positioned at the left and right sides, like this, expanded the spacing between adjacent two soft magnetic mediums, then, the ferromagnetic material on clean soft magnetic medium.
Here, soft magnetic medium is freely to rotate and be arranged in fluid passage.Because soft magnetic medium is freely to rotate in fluid passage, enter behind 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 self magnetic force, soft magnetic medium rotates into naturally, the line of both sides projection is parallel with magnetic direction, and making the spacing between two adjacent two soft magnetic mediums is minimum; Leave behind magnetic field, under the acting in conjunction in cleaning action power (impacting as vibrations, cleaning fluid) in conjunction with the gravity of the ferromagnetic material adhering to, soft magnetic medium upset, makes the spacing between two adjacent two soft magnetic mediums become large.
Due to when the ferromagnetic material, spacing between adjacent two soft magnetic medium projections is little, can effectively draw through the ferromagnetic material that comprises weak magnetism magnetic material in the fluid between adjacent two soft magnetic medium projections, therefore, remove ferromagnetic material effect very good, when clean soft magnetic medium, by rotating ferromagnetic material, one, can effectively destroy and remain in the magnetic force on ferromagnetic material and be blocked in that ferromagnetic material that the extruding force of the ferromagnetic material between adjacent two soft magnetic medium projections causes is close to soft magnetic medium projection and the generation that is not easy clean situation, the ferromagnetic material squeezing between adjacent two soft magnetic medium projections is loosed off, and offset the suction of the residual magnetic force of ferromagnetic material to soft magnetic medium projection by soft magnetic medium rotatory force, so that ferromagnetic mass-energy is by self gravitation and the extraneous vibration force applying, flush fluid (comprises gas, liquid) flushing ability rinses and cleans from soft magnetic medium projection, the spacing of adjacent two soft magnetic mediums that expand is also conducive to passing through of ferromagnetic material and flush fluid.
Here, the cross section of soft magnetic medium is square or approximate square or rhombus or near-rhombic or regular hexagon or nearly regular hexagon or ellipse or approximate ellipsoidal.
Magnetic separation type fluid iron-removing device of the present invention is to realize like this, comprise magnetic field, fluid passage, be arranged on several layers in the fluid passage soft magnetic medium layer being formed by several soft magnetic mediums, soft magnetic medium cleaning mechanism, its special feature is that the symmetrical part of both sides in the cross section of every 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, between adjacent two soft magnetic mediums of every layer, be arranged in parallel, soft magnetic medium rotates and is arranged in fluid passage.
Here, soft magnetic medium freely rotates the arranged outside being arranged in fluid passage or in fluid passage the rotating drive mechanism that drives every soft magnetic medium to rotate.
During work, by rotating drive mechanism, drive all soft magnetic mediums to rotate, the adjacent two soft magnetic mediums protrusion positions of every layer are oppositely arranged, making the spacing between two adjacent two soft magnetic mediums is minimum, then several layers of soft magnetic medium are placed in magnetic field, import fluid, by soft magnetic medium, remove the ferromagnetic material in the fluid flowing through, 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 to magnetic field, by rotating drive mechanism, drive all soft magnetic mediums to rotate, make the two ends of vertical range minimum of the both sides in soft magnetic medium cross section 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 approximate square or rhombus or near-rhombic or regular hexagon or nearly regular hexagon or ellipse or approximate ellipsoidal.
Compared with the prior art the present invention, has and comprises weak magnetism magnetic material, simultaneously in draw fluid effectively, can effectively to soft magnetic medium, carry out clean advantage again.
