Description
The present invention relates to the iron that abrasive dust is used in a kind of analytic liquid body medium and compose the method for work and device thereof, be particularly related to a kind of ferromagnetic abrasive dust that is used in the separating liquid medium, make ferromagnetic abrasive particle by size regularly segmented deposition on iron spectrum substrate, the spectrum sheet is observed, thereby the iron that abrasive particle carries out qualitative and quantitative analysis is composed the method for work and device thereof.
When making the iron spectrum sheet that abrasive dust is used in the analytic liquid body medium with existing analyzing ferrogram machine, the flow direction of the fluid to be measured medium on it all is vertical at on-chip projecting direction with the magnetic line of force of field region, used ferrograph basic structure is with two block permanent magnets and pole shoe, yoke is formed a rectangular gap magnetic field, the magnetic line of force of its work field region is at the flow direction perpendicular quadrature of on-chip projecting direction and liquid medium (as oil sample), therefore, after oil sample was extracted on the substrate by peristaltic pump, the ferromagnetic particle in the oil sample was deposited on the substrate by size in magnetic field force effect lower edge magnetic line of force direction.Because the magnetic line of force of its work field region is at on-chip projecting direction and liquid medium flow direction perpendicular quadrature, the deposition that at first flows through the ferromagnetic particle in the liquid medium in work magnetic field certainly will play inhibition (as " dykes and dams ") to follow-up liquid, and the track of liquid stream is affected.Especially near the liquid medium inflow end in work magnetic field,, make the zone of the deposited particles formation " spindle shape " in whole work magnetic field because the ferromagnetic particle settled density is big.The packing phenomenon of inlet end sedimentary province field width and particle is more serious, thereby has a strong impact on the reliability of spectrum sheet qualitative and quantitative analysis.In addition, the angle of inclination of substrate can only be 1-2 ° because of the influence that is subjected to magnetic field intensity, because if the excessive inlet end in inclination angle is too far away from the magnetic field distance, magnetic field intensity there is too little, will influence deposition efficiency, and impel liquid medium little along the downslide component that substrate flows, liquid flow is slower, the contamination particle of some nonferromagnetics has time enough to deposit on substrate, many contamination particles is arranged simultaneously because of before " climbing only dykes and dams " be blocked in " strut rail " ferromagnetic field particle chain in liquid medium stream.Therefore this analyzing ferrogram machine dirt-removing power when making the spectrum sheet is very poor, and contamination particle is stayed on the substrate in a large number, even " flooded " the interested ferromagnetic particle of people, and cause qualitative iron spectrum to observe difficulty, quantitatively iron spectrum reading also causes extreme inaccurate because of the contamination particle shading.
For guaranteeing that liquid medium above the work magnetic field of all flowing through on the iron spectrum substrate, needs fixed current limliting groove on substrate, this just makes substrate make difficulty, cost height.
The liquid medium of existing rotary-ferrograph and magnetic line of force direction tangent (magnetic line of force for radially, liquid medium flows through work magnetic field along hand of helix) have certain angle therebetween.And this rotary-ferrograph because of must have whirligig and its rotating speed of control steadily and the electronic circuit of record rotating speed cause its complex structure, price is more expensive.
The objective of the invention is to propose a kind of liquid medium flow direction and magnetic line of force in work magnetic field of making and compose the sheet method for making at the iron that on-chip projecting direction is parallel to each other; The liquid medium that has a ferromagnetic particle is deposited on the ferromagnetic particle piecewise to form iron spectrum sheet on the substrate flowing through work field region that several are parallel to each other, are mutually independent, discontinuous on the substrate.For this reason, the present invention proposes segmented deposition formula ferrograph for a kind of simple in structure, cheap, the reliable operation that reaches that this purpose designs.When becoming spectrum with this ferrograph, iron spectrum substrate can with magnetic head with arbitrarily angled inclination to adapt to the needs of removing or keeping dissimilar non-ferromagnetic debris.The magnetic field intensity in the magnetic field that the perform region is parallel to each other can be mutually the same and different, and its arrangement can be linear or nonlinear, but to increase progressively or evenly distributed for good.The purpose of doing like this is: the chain sedimentary province and the liquid medium flow direction that form of the ferromagnetic particle of deposition is consistent earlier for (1) liquid medium flow direction parallel with the direction of the projection of the work field region magnetic line of force on the spectrum sheet (and with the magnetic line of force acute angle) each other, can not cause the accumulation of particle.(2) substrate and magnetic head are convenient to cleaning with arbitrarily angled inclination and are removed contamination particle when the inclination angle is 1 °-2 ° (but the interested non-ferromagnetic debris of retention analysis personnel) again.
The method for making of the iron spectrum of the segmented deposition of the present invention's proposition is for this reason:
1, on the substrate that tilts, forms the shape magnetic field, bar crack of longitudinal separation, the intensity in this each shape magnetic field, bar crack is linearity or nonlinearities change from the arrangement of inclination top from the below of substrate, to spare strong or to increase progressively to good, and the magnetic line of force of the field region in each shape magnetic field, bar crack is parallel with the substrate longitudinal direction at on-chip projecting direction.
2, instillation fluid to be measured medium, keeps flowing in the parallel direction of on-chip projecting direction with the magnetic line of force of each bar crack property field region, and crosses over each slit, magnetic field along the inclination substrate according to its gravity on described substrate.
3, take off substrate, preserve and be deposited on on-chip abrasive dust iron spectrum for analyzing usefulness.
This step also can be described as:
(1), on substrate, form longitudinal separation, magnetic field intensity be linear or nonlinear variation, with increase progressively or even be by force good, and the magnetic line of force of field region is in several crack property magnetic fields of on-chip projecting direction and substrate parallel longitudinal.
(2), according to test solution body medium pollution level substrate is tilted, arrange under the situation about increasing progressively in magnetic field intensity, make the most weak magnetic field of magnetic field intensity be positioned at eminence, annotate and drip the test solution body medium on substrate, make the gravity of test solution body medium by itself, maintenance is flowed in the parallel direction of on-chip projecting direction with the magnetic line of force of on-chip field region and is crossed over each magnetic field.
(3), take off together with substrate, because of bar crack shape the action of a magnetic field segmented deposition is composed at on-chip iron.
The device that the method that proposes with the present invention is made segmented deposition iron spectrum be segmented deposition formula ferrograph mainly by magnetic head, substrate, current limiting plate and fulcrum arrangement are formed.The magnet that described magnetic head has or the polylith parallel interval is placed, perhaps also can be the filling block parallel interval placement that one or more rectangle magnet nonmagnetic substance the same with described rectangle magnet geomery with one or more made, " class wedge shape " pole shoe that the one deck that respectively reclines above described rectangle magnet or rectangle magnet and filling block is made with high permeability material, should have the gap of filling between " class wedge shape " pole shoe with the non-magnetic material, the tabular yoke iron that below described rectangle magnet and filling block, reclines and settle a high magnetic conductive material to make, described tabular yoke iron two ends respectively recline and settle " class wedge shape " yoke of a high permeability material, should " class wedge shape " yoke respectively and have the gap of non-magnet material filling between above-mentioned " class wedge shape " pole shoe, thereby constitute magnetic circuit system.All fill nonmagnetic substance in the space between described pole shoe, yoke and rectangle magnet and filling block (if having filling block).Magnetic head is integrally placed shell.
Substrate is placed on the upper surface of magnetic head, recline with the upper surface of described " class wedge shape " pole shoe, " class wedge shape " yoke, therefore on substrate, the top that is positioned on the gap between " class boot-shaped " yoke and " class boot last " pole shoe forms at interval, separate magnetic field parallel to each other, and the magnetic line of force of this field region is at on-chip projecting direction and magnetic head parallel longitudinal.
Current limiting plate places on the substrate, current limiting plate is made by the nonwettable material of liquid medium, polytetrafluoroethylene for example, current limiting plate is tabular, its one side that contacts with substrate has the rib with some longitudinal extensions of its all-in-one-piece, and one be positioned at the lengthways of rod termination and this lengthways of rod joins and the horizontal rib of all-in-one-piece, the current limliting groove that constitutes between the lengthways of rod have a through hole near horizontal rib place so that the fluid to be measured medium injects and along mobile along substrate in the current limliting groove institute limit scope.
The shell that magnetic head an is housed end longitudinally is articulated on the fulcrum arrangement, the magnetic head other end is supported on and promotes magnetic head and make on its magnetic head inclination stationary installation that favours different degree of tilt, and magnetic head is together with substrate placed on it and current limiting plate can tilt in 0-85 ° of scope and fix.
Because it is that the magnetic line of force of field region on flow direction and the substrate of test solution body medium is parallel in on-chip projecting direction direction that the iron that the present invention proposes is composed as method.According to the geometric position in shape magnetic field, bar crack, the ferromagnetism abrasive dust is with segmented deposition, because the magnetic that big abrasive dust itself has is apart from big, in following magnetic field force induced big deposition earlier of identical external magnetic field effect; Deposit behind the in like manner less ferromagnetism abrasive dust.Therefore near the deposition earlier of big abrasive dust in the magnetic field of working together that splashes into a little, the work abrasive dust size that deposits in the magnetic field of bar crack shape a little far away is gradually little from splashing into, and the average-size that is to say the abrasive dust that deposits in the work magnetic field is from splashing into far away more more little of a distance.Therefore be highly advantageous to the qualitative and quantitative analysis of iron spectrum, and degree of tilt is adjustable, is applicable to that the liquid medium of different pollution levels is made the iron spectrum, dirt-removing power is also strong, and its structure is very simple in addition, and cost is very cheap.
That is to say that the iron that the present invention proposes a kind of segmented deposition composes the method for work, steps of the method are:
