Device from the fluid medium separation of ferromagnetic materials

The present invention relates to from the device of fluid medium separation of ferromagnetic materials.

The present invention can be used for chemistry, metallurgy, machinofacture, thermal engineering, biological industry and sewage and gas cleaning aspect, be specially adapted to polishing purification for example water of condensation, recirculated water, oil, ammonia, alkali, steam, gas and other fluid mediums, to remove equipment corrosion product, machine and mechanical component wear debris, dispersive oxide skin etc. wherein.

At SU, A, described in 1029990 a kind of from fluid medium the device of separation of ferromagnetic materials.This device comprises a columniform working spaces, and the outer setting of this chamber has a magnetizing system, and the ferromegnetism weighting material of making the porous plate form is equipped with in its inside.The working spaces has the feeder sleeve that needs the cleansing fluid medium and the outlet pipe of cleansing fluid medium.

In known devices, porous plate is that the height along the working spaces is equally spaced.Simultaneously, between porous plate, form the slit to allow the fluid medium that is cleaned pass through.Bore edges place on the plate that forms the non-uniform magnetic field district produces and is cleaned the medium contamination precipitation.But non-uniform magnetic field is not strong to the magneticaction of these regional impurity particles.In addition, all non-uniform magnetic field districts have roughly the same magnetic field bump in the volume of whole working spaces, can not purify the fluid medium of the impurity that contains different degrees of scatter, different magnetic so effectively, in order to remove these impurity, in the whole volume of working spaces, different magnetic field bumps must be arranged.

In addition, in known devices, be to be rigidly connected and can not to move mutually and separate between plate and the plate, this makes and can not guarantee to regenerate effectively and correspondingly can not guarantee to clean well the impurity that plate is detained to remove it.

SU, A, 1152618 also narrated a kind of from fluid medium the device of separation of ferromagnetic materials, this device comprises a working spaces, in the chamber, be provided with the ferromegnetism weighting material that has the plate form of a plurality of perforation with polylith, these perforation have decorative pattern shape ridge, the orientation of this ridge and the plane of porous plate have angle, this device also comprises and is used for interacting with ferromagnetic filler and making its magnetized magnetizing system, is used for the inlet tube of the fluid medium input service chamber that is cleaned and is used to receive outlet pipe by the fluid medium that has purified behind the weighting material.

In known devices, the plate with same size hole comprises dapple convex part, and this convex part forms a plurality of non-uniform magnetic fields district, and the non-uniform magnetic field value in these districts is usually greater than the value in the porous plate at no convex part.This device can be worked when purification contains the fluid medium of the globule size impurity particle all identical with magnetic effectively.Change as the purification medium form, promptly this medium contains at the globule size impurity different with aspect of performance, at this moment just needs to change the plate weighting material, and this weighting material is of different sizes and void distribution rate and decorative pattern convex part.The viscosity that is cleaned medium also has significant effects to the selection of purification efficiency and weighting material.Existence with plate of the hole of same size and ridge and same distribution density causes working inconsistent in cleaning section along the weighting material in the each several part volume of working spaces's height in this device when the cleansing fluid medium.The bottom of weighting material volume (near outlet pipe) is very fast by impurity contamination, and the contamination at its middle part is slower, and top (near inlet pipes) is then slower.At this moment, the time between twice successive processes of step for regeneration will be depended on the work of lower floor's weighting material, and promptly filtration cycle will shorten.

Simultaneously, in most occasions, the actual fluid medium that is cleaned contains its dimensional change scope and is 0.01-10 micron and bigger impurity particle, and to for example metallurgical recirculated water, the required purification levels that reach of fluid medium such as thermoelectric power station water of condensation must be that residual impurity content is 10 ^-4-10 ^-9(weight).In addition, impurity has different magnetic: from paramagnetic to ferromagnetic, and the fluid medium that is cleaned from gas to water of condensation, the lubricated diversified variation of wet goods, these media have different viscosity.Conventional device can not guarantee the medium that contains different size, different magnetic impurities is reached required purification level owing to structural characteristics, can not guarantee that whole weighting material reaches same effectively purification efficiency.

Task of the present invention is the device of development separation of ferromagnetic materials from fluid medium, and the ferromegnetism packing structure that this device has can guarantee under the situation that reduces power consumption the fluid medium of different viscosity with the ferromagnetic particle that contains different sizes and different performance effectively to be purified.

Essence of the present invention is, from the device of fluid medium separation of ferromagnetic materials, include a working spaces, be provided with the ferromagnetic bosom weighting material with the plate form of a plurality of perforation of polylith band in this working spaces, the edge of the perforation on this plate has decorative pattern shape convex part.The orientation and the board plane of convex part have angle, tripping device comprises that also one is used for interacting with the ferromegnetism weighting material and making its magnetized magnetizing system, inlet pipe and the outlet pipe that can receive of a fluid medium input service chamber that desire can be purified by the fluid medium that had purified behind the weighting material, according to the present invention, the distribution density of hole on the plate, its size, profile, the size and dimension of convex part, gap between the plate, magnetic of impurity particle in the fluid medium that purifies according to need all, its size (dispersity), the concentration of fluid medium and viscosity are selected by the variable volume ground of working spaces.

In order to guarantee with the gap adjustment between the plate preferably to make plate to required size, make it have identical curve shape and elastomeric pad is set between them by the rubber-like material.As elastomeric pad, can the type of service simple elements, but must guarantee that multilayer plate where necessary has compression in various degree, and guarantee that when being switched on or switched off magnetic field decorative pattern shape convex part contacts or do not contact with adjacent plate surface.

For compression (approaching) degree of regulating plate, the additional Magnetic Field Source that preferably has a reduced size, make Magnetic Field Source be arranged on device the working spaces the outside so that its when being switched on or switched off, guarantee and the magnetic vector of plate weighting material magnetizing force effect axis orientation along the working spaces, it is close to possible minimum clearance that plate is transferred, or making plate loose, the spacing that is about between the plate is increased to required size.

For the ease of changing the distance between the plate, particularly in order to make it separately when regenerating, preferably alternately they are contained in the working spaces continuously: one recessed, another projection.

The meticulous purification of low-concentration liquid reaches required level in order for example to guarantee to make, the essential number that increases the High-gradient Magnetic place, in the case, preferably decorative pattern shape convex part is made the cusp form, partly make additional hole with the cusp that size is less, the edge of this hole constitutes certain angle with its auxiliary cusp and limb plane, and simultaneously, the number that is provided with the main limb that replenishes hole is preferably increased to outlet pipe by inlet tube gradually along the length direction of working spaces.This can make filler that the working hour of device in the scavenging process operation extends to whole volume by impurity fully equably till the filling, simultaneously, and the economy that has increased the volume of filtration cycle time and absorption and increased device on the whole.

The end of the ferromagnetic filler plate of each front and the front end of each back plate can be coupled together, make to form zigzag band by plate along the axis of working spaces.

Under many circumstances, plate can be arranged in parallel and the direction along inlet tube to outlet pipe reduces two distances between the adjacent plate gradually.

At this moment, should make the height of decorative pattern convex part equal two distances between the adjacent plate, the end of front plate is contacted with the surface of back plate.

The direction of pore dimension along inlet tube to outlet pipe of plate reduced gradually, can make the different impurity of dispersity on the whole height of plate weighting material, uniform precipitation be arranged like this.

For reasonableness and the economy that guarantees scavenging process, according to the magnetic of impurity particle in the fluid medium that is cleaned, its size and the viscosity of fluid medium, the decorative pattern convex part can be made the annular of changes of section, its cross section increases to its bottom gradually from the top of convex part.

In order to increase the number of the High-gradient Magnetic place on the ring-type convex part end surface, preferably be made into spination.

In order to increase surface, preferably the decorative pattern convex part is made the chimb form of outwards rolling with respect to the hole center along the circumference of hole for contamination precipitation.

Be to increase the density of arranging of plate, the magnetic diffusivity of whole plate layer and weighting material and be cleaned the interaction of magnetic force between the impurity particle in the medium can increase a kind of additional decorative pattern ridge of core bar shape to plate.

In this case, the length that is rigidly fixed in core bar on the even number plate can equal the spacing of per two immediate odd number plates.And in other cases, the length of core bar can be less than the spacing of per two immediate odd number plates.

Core bar can be made the form of flexible ferromagnetic wire harness.

Also core bar can be made the form of variable cross-section.

In addition, core bar can be made little tubularly, can reduce the fluid resistance of weighting material like this.

Make helical when tubular when magnetizing system, preferably make plate become the flat circle plate-like and the quantity of the decorative pattern convex part of each plate is increased to the center gradually by the periphery of disk.

If magnetizing system is made bipolar electromagnets, then the magnetic pole of electromagnet is close to the surface of working spaces, in the working spaces, the flow direction of the fluid medium that is cleaned is transverse to the magnetic field induction direction vector, preferably with the decorative pattern convex part of plate by distributing like this, make it increase away from the quantity in electromagnet poles zone at each plate.

Plate can be made the coaxial cylindrical format surface of working spaces, at this moment, successively decreased in the gap of adjacent plate from inlet tube to outlet pipe.

It is cylindrical also plate can being made appearance, and section is spiral helicine form, and at this moment, should successively decrease to outlet pipe from inlet tube in the gap of adjacent plate.

The advantage of the device of separation of ferromagnetic materials from fluid medium that makes by the present invention is, owing in the ferromegnetism weighting material, select and prepare the void distribution density of plate, its size, profile, during the size and dimension of convex part, all according to the magnetic of iron magnetic impurity particle in the fluid medium that is cleaned, its granular size (dispersity), the concentration of fluid medium and viscosity, spacing between the plate, variable volume ground by the working spaces is selected, under permissible low power consumption situation, can guarantee to reach high-caliber purification with different magnetic impurity particulate materials to containing different size, no matter this material is liquid or gaseous media, also no matter its viscosity is greatly or little all irrelevant.

Can be fast in device of the present invention and realize the regeneration of ferromegnetism weighting material effectively.Because the Magnetic Field Source of exist replenishing, so the packing density of very easy adjusting weighting material technically, working spaces is outside also can to guarantee that the synergistic additional Magnetic Field Source of sheet weighting material magnetic force reaches by means of being installed in for this.

Make the plate of curve shape with resilient material, be provided with elastomeric pad between plate, owing to can compress or loose (separate) reduced power consumption when change plate packing density, this has guaranteed high-quality regenerative process.When particularly between by plate, interconnecting along working spaces's axis form the zig-zag belt a kind of install guarantee in the scheme to change places very much widely for example in from 0.1 to 0.6 the scope to the packing density change of weighting material.

According to the present invention, the additional decorative pattern convex part of making the ferromagnetic core rod type and install and be fixed on the odd number plate is assemblied on the device, can increases the quantity of the packing density of weighting material, the average magnetic field influence value in the weighting material, High-gradient Magnetic place and the purification level of fluid medium.According to the clean shape and size of not being changed the type of matter and the purification level that its requires being selected core bar of quilt.

Some device schemes are arranged, be about to the form that plate is made coaxial cylindrical surface or cylindrical surface, and its section is a volution, such device scheme, convenient especially when its assembling or dismounting.

In the following description and the drawings, same figure number is represented identity element.

The device from the fluid media (medium) separation of ferromagnetic materials of advising shown in Fig. 1,2,3, it comprises an operating room 1. Operating room 1 by with end cap 2 ' cylinder-shaped body 2 consist of, be provided with therein ferromagnetism filler 3, this filler forms with a plurality of elastic linear plates 4 and with penetrating hole 5, the hole periphery has the decorative pattern projection 6 of cusp shape, and the orientation of this part and plate plane consist of an angle. In addition, decorative pattern projection 6 have with auxiliary cusp 7 auxiliary penetrate hole 5 '. Between plate 4, be provided with elastomeric pad 8, can use waterproof and acidproof rubber, natural rubber, also can use other well known elements that can realize the elastomeric pad function and annex as gasket material.

Device also comprises magnetizing system 9, and it is installed in the outside of operating room 1, and in the embodiment that provides, operating room 1 is made by the several-layer solenoid 10 that segmented consists of. In order to change the spacing of plate 4, just in order to regulate the packing density of filler 3, be equipped with and replenish magnetic field sources 11 operating room 1, it be installed in the top cover 2 of 1 outside, operating room ' on, it can guarantee to take place with plate filler 3 interaction of magnetic force. In the inadequate situation of the effect of 11 pairs of plates 4 of a magnetic field sources, can not guarantee that just the packing density of plate 4 produces necessary change, then in second additional magnetic field sources (not shown in FIG.) of lower cover 2 ' arrange. Magnetic field sources 11 is made the electromagnets that includes magnetic core 12 and conductive coil 13. Increasing at the diameter dimension of main body 2, for example is 0.5 meter and when bigger, and then also can to make helical tubular for magnetic field sources 11. At this moment, replenish the side surface that magnetic field sources 11 is arranged on main body 2, similar to solenoid 10, coaxial comparatively convenient with main body. Fluid media (medium) input and discharge operating room 1 in order to be cleaned He purified correspondingly have inlet tube 14 and outlet 15.

Plate 4 is the circular planar disk-like that are arranged in parallel in Fig. 1,2,3, the spacing between them from inlet tube 14 to outlet 15 direction successively decrease. The quantity of main decorative pattern projection 6 and auxiliary limb 7, their height and hole 5 and 5 ' size also be 15 to some extent changes from inlet tube 14 to outlet. Such design feature guarantees to have improved the run duration in the effective purification to the subsequent regeneration operation at whole fillers 3 of when work " alluvial " impurity particle equably. Spacing between the plate 4 changes by means of elastomeric pad 8, this pad can compress or unclamp from additional magnetic field sources 11 and adding under the strong pressure of solenoid 10, has guaranteed the packing density of necessary filler 3 and has guaranteed projection 6 with the Surface Contact of plate 4 or do not contact.

Shown in Fig. 2,3, when the height of projection 6 reduces, hole 5 and 5 ' distribution density increase, namely when along the hole 5 and 5 on the unit are that is cleaned plate 4 in the running path of medium ' quantity when increasing, the corresponding increase of quantity in the average magnetic field influence value in the filler 3 and non-uniform magnetic field district. Such as Fig. 1,2, shown in 3, in the situation that the amount of metal of plate 4 is identical in unit volume, the packing density of plate 4 that is whole filler 3 volumes is constant, magnetic field can be improved to the magneticaction of impurity particle, this is owing to taked the cause of more following measures, namely in main cusp-decorative pattern projection 6, formed the hole 5 that replenishes ', hole 5 ' the edge have and the angled auxiliary cusp 7 of rolling in main cusp plane, simultaneously, with replenish hole 5 ' the number of main projection 6 along the operating room 1 vertically increase progressively to outlet from inlet tube 14.

According to the present invention, be shown among Fig. 4,5,6 with Fig. 1,2, other device scheme of 3 scheme phase regions and include shaped form elastic board chip 4 ' and second auxiliary magnetic field source 16, this magnetic field sources is electromagnets, it is arranged on the lower cover 2 of 1 outside, operating room ' locate. Magnetic field sources 16 includes magnetic core 17 and solenoid 18, and its mounting means and magnetic field sources 11 are similar. Plate 4 ' have the curve shape of same curvature and along the operating room 1 height arranges equably, one with another between distance equate. Along be cleaned the plate 4 of media flow approach ' on decorative pattern projection 6 have additional hole 5 ', have and the angled auxiliary limb 7 of rolling in the plane of projection 6 at the edge of hole. Simultaneously, 1 length direction increases progressively (in order to simplify tracing from inlet tube 14 to outlet the number of main projection along the operating room, not shown hole 5 in Fig. 4,5,6 ' and projection 7, they to Fig. 2 and Fig. 3 in projection 7 and hole 5 ' shape similar). For the closed magnetic circuit of apparatus for establishing, in the outer setting of solenoid 10 ferromagnetism shell 19 is arranged, can reduce like this magnetic field and be lost in the surrounding medium and go. The existence of electromagnet 16 has guaranteed can carry out necessary adjusting to the density of plate filler 3, and is just rare close with accent plate 4 ' accent. The thickness of filler layer 3 reach 1.0 meters and bigger situation and must fierce vibrations plate 4 in order for example to eliminate at plate 4 ' lip-deep ferromagnetism impurity ' occasion under, exist second additional magnetic field sources 16 advantageous particularly.

Fig. 5,6 show plate 4 when cleaning procedure (Fig. 5) and step for regeneration (Fig. 6) ' the position. In Fig. 5, top plate 4 ' the decorative pattern projection 6 of cusp shape be in bottom plate 4 ' the Surface Contact state, can form the High-gradient Magnetic place in the position that the contamination precipitation process takes place like this. Rely on magnetic field sources 11,16 and elastomeric pad 8 be used for make in the situation that decorative pattern projection 6 and plate 4 ' Surface Contact point leave, effectively regenerate.

At so a kind of equipment scheme shown in Fig. 7,8,9, wherein the shaped form plate 4 in the operating room 1 ' continuously alternately arranges: plate 4 ' recessed, a projection is elastomeric pad 8 between them. So alternately arrange have flexible shaped form plate 4 ', can be in the scope of broadness the technical packing density that is easy to change filler 3, realize increasing or reduce projection 6 and plate 4 ' contact point and the quantity that correspondingly increases and decreases the non-uniform magnetic field district. The quantity of decorative pattern projection 6 increases progressively along the flow path that is cleaned medium in operating room 1. For example, in the lower floor of filler 3, decorative pattern projection 6 do not comprise replenish hole 5 ', and from half beginning of floor height of filler 3, additional hole 5 ' and additional ridge that cusp 7 forms correspondingly occur appears in decorative pattern projection 6.

Device scheme shown in Figure 10, different from Fig. 1 scheme, it includes the plate 4 of patterned projection 6, connect like this between this plate, each the preceding plate 4 be connected with the starting end of next plate 4 with oneself end so that 1 axis forms toothed belt by plate 4 along the operating room. The en plaque filler 3 of saw tooth belt shape has guaranteed effectively the separately precipitation of plate 4 and loose deposition, can make like this regeneration proceed to required level, particularly when purifying high concentration and being stained with the medium of oil, for example when decontamination cycle water, the density of assembling this moment must be not high and should reduces the bed thickness of filler 3.

Provided among Figure 11 according to device scheme of the present invention, wherein elastic curve shape plate 4 ' continuously alternately arranges: one is recessed, a projection, simultaneously, plate 4 ' the plane arrange on 1 axis orientation ground along the operating room. Plate 4 when step for regeneration ' separately and vibration be what to be undertaken by the electromagnet 20 that is arranged on operating room's 1 side surface. Can be worked independently of one another by the electromagnet 20 that 1 each magnetic core 21 that highly distributes and solenoid 22 along the operating room form. In this device scheme, solenoid 10 is made the form of 1 separate part that highly distributes along the operating room. The orientation of the magnetic core 21 of electromagnet 20 perpendicular to the plate 4 in the gap that is arranged between solenoid 10 parts ' the plane and closely be attached to its end face on the side surface of operating room 1. In step for regeneration, switch on and off pulsedly electromagnet 20, guaranteed plate 4 ' carry out pulse oscillating, cause plate 4 ' separately, make the impurity particle precipitation loose and so that can easily they be removed.

The difference of scheme is among device scheme shown in Figure 12,13 and Fig. 1, plate 4 is equipped with additional decorative pattern projection 23, this part is made core bar shape, and its length equals the spacing between per two nearest odd number plates 4, and core bar is rigidly fixed on the even number plate 4. Ferromagnetism core bar 23 can have outside the shape of the engraved pointed portion 24 of surface band (Figure 14,15) or have the cross section and dwindles at core, the shape (Figure 16) of the pointed portion 25 that enlarges at end portion, perhaps resemble flexible thin wire bundle 26(Figure 17) or resemble needle-like core bar 27(Figure 18), perhaps like the shape (Figure 19,20) at the engraved tubule 28 of end face band.

When utilizing this device to purify mainly to contain medium size and coarse grain to disperse the high concentration medium of impurity, the length of core bar 23 is less than the distance between the immediate odd number plate 4 (Figure 12,13). Use reasonability and the validity of the plate filler 3 that makes up with core bar 23 to depend on following factor. Spacing between adjacent hole 5 hour, in the plate 4 that does not have core bar 23, the density reachable of the upper holes 5 in plate 4 surfaces is to maximum, this depends on the condition of hole 5 perforation on the thickness of plate 4 and material and the plate 4. On the connecting plate that forms between the hole 5, can wear additional hole, but more much smaller than the diameter of main hole 5. The result forms quite undersized limb, therefore, and the contact that only depends on the projection 6 of main (big) hole 5 to form between the plates 4. In the device scheme of advising shown in Figure 12,13, owing to the additional contact point between core bar 23 and the plate 4 increases, namely the number of effective magnetic force settling zone of impurity increases filler 3 in the quantity of the contact point between the plate 4.

In addition, core bar 23 is introduced the packing density that increases on the whole filler 3 in the plate 4, namely be increased in the ferrimagnet concentration of unit volume inner stuffing 3, cause under same external magnetic field strength conditions, increasing the magnetic conductivity (M) of filler 3, therefore, increase the magnetic field induction effect, improve magnetic field to the magneticaction of precipitated impurities, and finally cause improving the efficient of purification process, this contains the medium of high degree of dispersion impurity in purification, for example heating power and nuclear power plant come out water the time advantageous particularly.

For the inhomogeneities of eliminating Distribution of Magnetic Field (when using electromagnet as magnetizing system, near the two poles of the earth and in the central area, and when using solenoid, near wall with the central area in) make core bar 23 by the material with different magnetic, these material payments are distributed in the changes of magnetic field in the filler 3, for example, in filler 3 zones of high magnetic field intensity, prepare core bar 23 by the magnetically soft steel with low carbon content, in the zone of low magnetic field intensity, then reached the material preparation of 5000-50000 by magnetic conductivity. In order to set up inhomogeneous district and to improve magnetic conductivity, the method for handy overstriking is made core bar 25(Figure 16) on two terminations. In the changes of section position of core bar 25, produce local (area) High-gradient Magnetic place, this can guarantee to improve the level of magnet purified process. Be this purpose, core bar section 24(Figure 14,15) the surface make the structure of trough of belt, and tubule shape core bar 28(Figure 19,20) end face make structure with rag, form the non-uniform magnetic field district at these projections. Needle-like core bar 27(Figure 18) height of formation non-uniform magnetic field district with the Surface Contact of plate 4 time, this has guaranteed the precipitation to weak magnetic impurity. In addition, needle-like core bar 27 in fact can be to not being cleaned the mobile resistance that causes of medium.

Core bar 23 is rigidly fixed on the even number plate 4, and core bar contacts with odd number plate 4 with its end in one case, and in another case not contact, this also depends on whether be necessary the condition of precipitation process in filler 3 volumes is united. For example, for avoiding core bar to contact with adjacent nearest plate 4, core bar 23 made quarter butt and be arranged in the zone of magnetic field intensity maximum of filler 3, under another kind of occasion, core bar 23 is made long bar come in contact with plate 4 and it is arranged in the littler zone of the magnetic field intensity of filler 3 to reach.

Core bar is formed in the quantity (the magnetic field concentration place sets up high-gradient magnetic field at this place) that tubule 28 shapes (Figure 19,20) that end face has cutting can increase contact surface and the cusped edge of filler 3 assemblies and purification medium. Hole in the pipe 28 is also as reducing the rate of filtration, namely in order to prolong magneticaction in the duration of precipitated impurities, because the effective cross-section scope of filler 3 has increased.

A little less than purification contains high dispersive during the liquid medium of magnetic impurity, set up a kind of intensity of the external magnetic field that on the purification medium direction of motion, increases with density, be to guarantee this point, for example can same direction increase solenoid 10 coil turn and same direction increase the plate 4 of filler 3 ' distribution density.

At this moment, thick be cleaned the medium impurity particle be deposited in plate 4 ' discontiguous projection 6 on, and the impurity of high degree of dispersion is by on the position that is deposited in projection 6 and plate 4 ' plane contact. In order to increase the High-gradient Magnetic place, use has the plate 4 of various shape decorative pattern projections 6, for example have the decorative pattern projection 29(Figure 22 that changes the ring section), this cross section increases progressively to the bottom from the top of projection 29 and contacts with adjacent plate along circumference. The characteristics of decorative pattern projection 30 shown in Figure 23 are, wherein make sawtooth at end face, thereby form some projections 30 and the circumference that adjacent plate 4 contacts, and have guaranteed a large amount of non-uniform magnetic fields district. Projection 31 shown in Figure 24 is made along the convex-edge shape of hole 5 circumference, and this chimb is outwards rolled with respect to hole 5 centers. The projection of this shape in the preparation manufacturability good and purify serious stain contain the medium of the dispersed impurity of seedy the time to use the plate 4 with decorative pattern projection 31 comparatively favourable. Projection 31 along hole circumference chimb form among Figure 24 can guarantee to have a plurality of contact points when contacting with plate 4, has in addition in the non-uniform magnetic field district of the cusped edge of outwards rolling near chimb, and coarse grain disperses and ferromagnetic impurity precipitates at this place.

For packing density and the magnetic conductivity that improves filler 3, the height of decorative pattern projection 32 is less than the distance (Figure 25) between two adjacent plates 4 on the plate 4, and plate 4 itself is made dapple shape and have projection or recessed unit at hole 5 distributing positions, recessed unit matches with the height of decorative pattern projection 32 with respect to the degree of depth on plate 4 planes, guarantees that projection contacts with next plate 4. At this moment, liquid medium is through the flow path length of filler 3, also can be arranged to interlace mode and obtains increasing owing to the hole 5 on the plate 4 that distributes successively. When purifying the medium of high concentration ferromagnetism impurity, for keeping the non-uniform magnetic field district can use plate 33(Figure 26 of groove line), between plate 33, be provided with the additional plate dividing plate 34 of projection 35, can increase medium through the flow path of filler 3.

When in the device of big productivity ratio, using solenoid 10 as magnetizing system 9 (Figure 27), in order to compensate the reduction of magnetic field induction value in the solenoid axle center district that volume is 20-30%, the void density that makes in this district each plate have the decorative pattern projection increases 20-30% than plate external zones. When using bipolar electric magnet 36 as magnetizing system 9 (Figure 28), its magnetic pole abuts against on the outer surface of operating room 1, the direction that wherein is cleaned media flow is transverse to the magnetic field induction direction vector, hole 5 with decorative pattern ridge distributes in such a way along each plate 4, so that in the zone on magnet 36 magnetic poles plate 4 farthest, the quantity of hole 5 increases 20-30% than the zone near magnetic pole.

Ferromagnetic filler 3 in device scheme shown in Figure 29 is made by plate 37, this plate is the coaxial cylindrical format surface, simultaneously, the inlet tube 14 that equals the place of operating room's 1 mid-height from being arranged on 1 side, operating room of the distance between the plate 37 successively decreases to the outlet 15 that is arranged on operating room's 1 end face. In device scheme shown in Figure 30, filler 3 is made up of plate 38, this plate is made the cylindrical surface form, its cross section is spirality, at this moment, distance between the adjacent turns of spiral 15 is successively decreased from inlet tube 14 to outlet, and the setting of pipe 15 is pointed the same during with the device scheme of top description Figure 29.

For reduce flux loss to around medium in, will be according to 1(Figure 31 of operating room of apparatus of the present invention) connect to assembly 39 with electromagnet 36 per two operating rooms 1, form the complex that is for example formed by three independences and autonomous work package 39. For example in the operation of bodies for purifying fluids medium, two assemblies 39 are in work, and another is regenerated.

Operating room 1 also can be by other mode and electromagnet 36 combinations (Figure 32), and form the toroid that for example is made up of 6 operating rooms 1 this moment, and wherein the magnetic core of electromagnet 36 is close on the main body of operating room with its end face part.

The device of separation of ferromagnetic materials is worked as follows from fluid media (medium).

The liquid that wish purifies or gaseous fluid medium are along inlet tube 14(Fig. 1) enter the operating room 1 that is full of ferromagnetism filler 3, filler is made a plurality of plate 4 forms that penetrate hole 5 of polylith band, has decorative pattern projection 6 along hole 5 peripheries. Making under the magnetic systems 9 formed electric field actions of multilayer nut pipe 10 shapes, the ferromagnetism filler that plate forms is magnetized, at this moment, on the contact position of decorative pattern projection 6 and plate 4, form the High-gradient Magnetic place, at this place, impurity is precipitated out (F=Hgrad H by the fluid media (medium) that is cleaned under the effect of magnetic force F, F is magnetic force herein, and H is magnetic field intensity, and grad H is this magnetic field gradient).

Change the quantity of decorative pattern projection 6 and auxiliary cusp 7, can make the level of bodies for purifying fluids medium process reach required design load. Owing to form the auxiliary cusp 7 that replenishes, the quantity of contact point can further be increased to 3-4 doubly. The quantity of High-gradient Magnetic place is corresponding growth also. By behind the filler 3, removed the bodies for purifying fluids medium of impurity and discharged along outlet 15. Simultaneously, in the device of advising, the height of the spacing of the quantity of decorative pattern projection 6, plate 4, decorative pattern projection 6 and shape thereof are according to size, its magnetic of impurity particle and be cleaned the viscosity of medium, along the flow path that is cleaned medium, 15 can change in the scope widely from inlet tube 14 to outlet. For example, the filler packing density can or change in larger scope 0.05 to 0.6. In addition, the size of the hole 5 of decorative pattern projection 6 not only according to the height of operating room 1, but also is arranged on (Figure 27,28) in the device changeably according to the plane of independent plate 4.

For example, for the impurity with weak magnetic and polymolecularity, use is drawn in Fig. 1,2,3,12, and is comparatively favourable with the device scheme that relatively large decorative pattern projection 6 is arranged in per unit volume filler 3. The packing density excursion to filler 3 of recommending simultaneously, is 0.4 to 0.6. In this case, the average magnetic field influence value in filler 3 reaches 1.2-1.6T. For the fluid media (medium) with ferromagnetism and coarse grain dispersion impurity, use the device scheme of on Fig. 7,8,9,10,11,21, drawing comparatively favourable. Herein, the density of filler 3 is preferably in interior variation of scope of 0.1-0.3. Average magnetic field influence value in the filler 3 reaches 0.4-0.7T.

In the technology that purifies sticking medium, when being necessary effectively to shake, vibrating with plate 4 separately, use to have shaped form elastic board chip 4 ' and have the device scheme of the plate 4 that connects to toothed belt comparatively favourable (Fig. 4,7,, 10,11,21).

In order to make filler 3 regeneration, disconnect magnetizing system 9, at this moment, the medium that has purified is passed on assembly 39 among 1(Figure 31 of operating room for subsequent use). In reproduction operation chamber 1, periodically, switch on and off to pulsed and replenish magnetic field sources 11,16,20. Under the short time strong magnetic field action, plate 4 is attracted to magnetic pole 11,20,16 places of magnetic field sources, and when disconnecting coil 13,18,22 magnetic field sources, plate 4 returns the starting position under elastic force and Action of Gravity Field. Repeat such switching on and off for several times. As a result, cause projection 6 to separate with the position of the contact point of adjacent plate 4, at this moment, contamination precipitation is loosened. The strain of plate 4 has reduced its remaining magnetic susceptibility, makes its size reach magnetic field induction value under the condition of work. Pass into compressed air by conduit 15, or the water-air mixture, loose contamination precipitation is washed into exhaust system.
