Opfindelsen angår en prøvebeholder til brug ved analyse af en heri anbragt materialeprøve af et strømmeligt, men ikke væskeformigt materiale, hvilken beholder omfatter en i sin væg anbragt analyseåbning, igennem hvilken materialeprøven 5 kan analyseres via en oven over anbragt analyseenhed, samt har midler til i prøvebeholderens materialegennemgangsretning at fraføre en analyseret materialeprøve og midler til i samme retning at tilføre en ny materialeprøve til analyse.The invention relates to a sample container for use in analyzing a sample of material of a flowable but non-liquid material, which comprises a wall of analysis located in its wall through which the material sample 5 can be analyzed via an above-mentioned analysis unit, and has means for to pass an analyzed material sample and means to apply a new sample of material for analysis in the same direction.
I industrielle anlæg, hvor forskellige pasta-, korn-10 og/eller pulverformige materialekomponenter blandes, er det vigtigt jævnligt at udtage og analysere prøver, som er repræsentative for blandingen på det pågældende tidspunkt.In industrial plants where various paste, grain-10 and / or powdery material components are mixed, it is important to regularly take and analyze samples representative of the mixture at that time.
Det er kendt at lede de udtagne prøver af det materiale, som ved blandingen produceres, til en prøvebeholder, der 15 er anbragt i direkte tilslutning til en materialeanalyseen-hed. Efter analysen ledes materialet videre fra prøvebeholderen og f. eks. til det producerede materiales afleveringssted.It is known to direct the samples taken from the material produced by the mixture to a sample container placed in direct connection with a material analysis unit. After the analysis, the material is passed on from the sample container and, for example, to the place of delivery of the produced material.
En kendt prøvebeholder er indrettet med en vægåbning, 20 som er lukket af en gennemsigtig vægdel, igennem hvilken materialeprøven inde i beholderen kan analyseres ved hjælp af analyseenheden. Prøvematerialet presses af en arbejdscylin-ders stempelstangsende i prøvebeholderen ud mod den gennemsigtige vægdel, der kan være en solid glasplade eller selve 25 dækpladen på analyseenhedens detektorhoved. Efter analysen trækkes stemplet tilbage, og den analyserede prøve fjernes.A known sample container is provided with a wall opening 20 which is closed by a transparent wall part through which the material sample inside the container can be analyzed by means of the analysis unit. The sample material is pressed by the piston rod end of a working cylinder into the sample container against the transparent wall portion which may be a solid glass plate or the cover plate itself on the detector head of the analyzer. After the analysis, the plunger is withdrawn and the analyzed sample is removed.
Før den næste prøve tilføres i beholderen, renses indersiden af den gennemsigtige vægdel, eller dens inderside i form af en tynd, oprullelig film udskiftes. Midlerne til rensning el-30 ler udskiftning af den gennemsigtige vægs inderside har de ulemper, at de er omstændelige, kostbare og driftssikkerhedstruende for prøvebeholderen og dermed også for det blandean-læg, som kontrolleres af prøvebeholderens analyseenhed.Before loading the next sample into the container, the inside of the transparent wall portion is cleaned or its inside in the form of a thin, roll-up film is replaced. The means for cleaning or replacing the inside of the transparent wall have the disadvantages of being cumbersome, expensive and operationally threatening to the sample container and thus also to the mixing system controlled by the sample container's analyzing unit.
Det er opfindelsens formål at afhjælpe ovennævnte ulem-35 per samt tilvejebringe en prøvebeholder, hvor analyseåbningen ved hver analyse er fri for forrige prøves rester, samt at dette opnås uden brug af udskiftelig film, glasplader eller DK 170899 B1 2 rensemidler.It is an object of the invention to remedy the above-mentioned disadvantages and to provide a sample container where the analysis opening is free from the residues of the previous sample at each analysis, and that this is achieved without the use of replaceable film, glass plates or cleaning agents.
Dette opnås ifølge opfindelsen ved en prøvebeholder, der er ejendommelig ved, at analyseåbningen er anbragt i en væg-zone, hvis inderside vender nedad, at analyseåbningen er af-5 lulckelig via en forskydelig vægdel, i det følgende benævnt et spjæld, at spjældet i sin åbenstilling er forskudt bort fra analyseåbningen, således at analyseenheden uhindret kan analysere den i analyseåbningen blottede materialeprøves overfladedel, og at prøvebeholderen har opstuvningsmidler, der er 10 indrettet til i analyseåbningen at anbringe en materialeprøves overfladedel, således at denne tager form efter indersiden af nævnte spjæld i dettes lukkestilling.This is achieved according to the invention by a sample container, characterized in that the analysis opening is arranged in a wall zone, the inside of which faces downwards, that the analysis opening is closable via a slidable wall part, hereinafter referred to as a damper, which its open position is offset from the analysis opening so that the analyzing unit can unobstructedly analyze the surface portion of the material sample exposed in the analysis opening and the sample container has pusher means adapted to place in the analysis opening a material sample surface portion so that it takes shape after the inside of said damper in its closing position.
Analysen med prøvebeholderen sker på følgende måde. Først lukkes spjældet i analyseåbningen, forrige materiale-15 prøve fraføres, hvorpå den eller de næste materialeprøver tilføres, og når næste analyse ønskes udført, standses tilførslen. Som følge af at opstuvningsmidlerne opstuver eller komprimerer materialet op ad spjældet i den lukkede analyseåbning, at analyseåbningen er anbragt i en vægzone, hvis in-20 der side vender nedad, og at opstuvningsmidlerne ophører deres opstuvningsfunktion, når en passende grad af materialekomprimering er opnået, kan materialeprøvens overfladedel nu ved forskydning eller åbning af spjældet bort fra analyseåbningen blotlægges, og ligger da glat og klar til analyse.The analysis with the sample container is done as follows. First, the damper is closed in the assay opening, the previous sample of material is dispensed, then the next sample (s) is fed, and when the next assay is desired to be performed, the supply is stopped. As a result of the dusting agents being dusted or compressed up to the damper in the closed analysis opening, the analysis opening being located in a wall zone facing downwards and the dusting agents ceasing their dusting function when a suitable degree of material compression is achieved, For example, the surface portion of the material sample can now be exposed by sliding or opening the damper away from the analysis opening, and is then smooth and ready for analysis.
25 Denne analyse kan hensigtsmæssig være af ikke-destruktiv art, for eksempel baseret på måling af refleksion, fotoemission, resonans, fasehastighed, luminiscens, fosforescens, duftmåling etc.This analysis may conveniently be of a non-destructive nature, for example, based on measurement of reflection, photo emission, resonance, phase velocity, luminescence, phosphorescence, scent measurement, etc.
Den udvalgte overfladedel forbliver stabil, fordi den 30 vender opad, og analyseenhedens detektorhoved kan føres helt tæt til overfladedelen uden risiko for tilsmudsning og deraf følgende krav om hyppig renholdelse.The selected surface portion remains stable because it faces upward, and the detector head of the analyzer can be brought very close to the surface portion without the risk of contamination and consequent frequent cleaning requirements.
Efter analysen forskydes spjældet tilbage fra sin åbenstilling til sin lukkestilling, således at fraførselsmidlerne 35 kan drive materialeprøven ud til klargøring af prøvebeholderen til næste analyse.After the analysis, the damper is moved back from its open position to its closing position so that the dispensing means 35 can drive the material sample out for preparation of the sample container for the next analysis.
Selv om opfindelsen især er velegnet til analyse, over- DK 170899 Bl 3 vågning og/eller styring af korn- og foderstofblandinger, er den også gavnlig indenfor den øvrige næringsmiddelindustri, i farve- og lakindustrien til kontrol af farvepigmentsam-men-sætninger, i byggeindustrien til kontrol af byggemateriale-5 råstoffer, i energi- og varmeproduktionen til indirekte forbrændingskontrol ved analyse af aske, og i plastindustrien til analyse af granulatsammensætninger.Although the invention is particularly well suited for analysis, monitoring and / or control of cereal and feed mixtures, it is also beneficial in the other food industry, in the paint and varnish industry for the control of color pigment compositions, in in the building industry for the control of building material-5 raw materials, in the energy and heat production for indirect combustion control in the analysis of ash, and in the plastics industry for the analysis of granular compositions.
Opstuvningsmidlerne omfatter hensigtsmæssigt dels en vibrationsføder, som er mekanisk sammenkoblet med prøvebehol-10 deren eller udformet integreret hermed, og dels et ud for og/eller efter analyseåbningen i prøvebeholderens gennemgangsretning aftagende gennemgangstværsnit. Ved valg af vibrationsføder til opstuvningsmiddel bliver endvidere førnævnte separate tilførsels- og fraførselsmidler overflødige, idet 15 vibrationsføderfunktionen også kan anvendes til velkontrolleret intermitterende tilførsel og fraførsel af materialet til analyseåbningen.Conveniently, the stowing means comprise a vibration feeder which is mechanically coupled to the sample container or formed integrally therewith and partly a cross-section decreasing before and / or after the analysis opening in the sample container's direction of passage. Furthermore, in selecting vibration feeder for dusting agent, the aforementioned separate supply and delivery means become superfluous, the vibration feeder function also being used for well controlled intermittent supply and delivery of the material to the analysis opening.
Som følge af nævnte aftagende gennemgangs tværsnit bevirker vibrationsføderens fremføring af materialet i prøvebehol-20 deren, at dette opstuves eller komprimeres op ad spjældet i den lukkede analyseåbning, og den overfladedel, der skal analyseres, ligger klar dertil, når en passende komprimering er opnået. Da denne komprimering er materialeafhængig, bestemmes den empirisk, og udtrykkes for eksempel i sekunder funktions-25 tid før vibrationsføderen standses.Due to the cross section of said decreasing passage, the feeding of the vibration feeder to the material in the sample container causes it to be sprayed or compressed up by the damper in the closed analysis opening and the surface part to be analyzed is ready for this when an appropriate compression is achieved. Since this compression is material dependent, it is determined empirically and is expressed, for example, in seconds of operation time before the vibration feeder is stopped.
Spjældet er i en enkel udførelsesform hensigtsmæssigt svingbart lejret til dets svingning mellem dets lukke- og åbenstilling. Derved har det desuden fordelagtigt vist sig, at materialeprøvens overfladedel ikke er tilbøjelig til på 30 grund af optrædende luftstrømme at ændre form, selv om spjældet åbnes hurtigt.In a simple embodiment, the damper is suitably pivotally mounted for its pivot between its closing and opening positions. In addition, it has been found advantageously that the surface portion of the material sample is not inclined to change shape due to the occurrence of air flows, although the damper opens quickly.
For at optage mindre plads til sin forskydning og tillade analyseenhedens detektorhoved at være stationært anbragt eller kun at behøve en ringe forskydningsbevægelse mellem sin 35 udgangsstilling og analysestilling er spjældet hensigtsmæssigt indrettet til fra sin lukkestilling først at føres vinkelret ud fra prøvebeholderen et stykke svarende til dennes DK 170899 Bl 4 vægtykkelse, og dernæst at forskydes langs dennes ydervæg indtil analyseåbningen er helt blotlagt. Eventuelt er det hensigtsmæssigt at kantstille spjældet en smule, før det føres vinkelret ud fra analyseåbningen, til undgåelse af 5 ovennævnte overfladebeskadigende luftstrømme.In order to take up less space for its displacement and to allow the detector head of the analyzer to be stationary or to require only a small displacement movement between its initial position and the analysis position, the damper is suitably arranged to first move from its closing position perpendicular from the sample container corresponding to its DK 170899 B1 4 wall thickness, and then to be displaced along its outer wall until the analysis opening is fully exposed. Optionally, it is advisable to slightly adjust the damper before it is perpendicular to the analysis opening to avoid the above-mentioned surface-damaging air flows.
Endelig kan spjældet i en yderligere fordelagtig udførelse udgøres af en langs prøvebeholderens udvendige overflade forskydelig vægdel, hvorved nævnte detektorhoveds afstand fra materialeprøvens overfladedel kan reduceres til 10 lidt over spjældets godstykkelse.Finally, in a further advantageous embodiment, the damper may be constituted by a wall part which is displaceable along the outer surface of the sample container, whereby the distance of said detector head from the surface portion of the material sample can be reduced to 10 slightly above the thickness of the damper.
Opfindelsen vil i det følgende blive nærmere forklaret i forbindelse med nogle udførelsesformer og under henvisning til tegningen, hvor fig. 1-3 viser en prøvebeholder med svingbart lejret 15 spjæld, set henholdsvis fra oven, bagfra i materialegennemgangsretningen og i længdesnit langs I-I i fig. 1, fig. 4-5 udsnit i fig. 3 i større målestokforhold og visende spjældet i henholdsvis lukket og åben stilling, og fig. 6-8 en prøvebeholder med langs dennes overflade 20 forskydeligt spjæld set henholdsvis fra siden, fra oven med spjældet i sin lukkestilling og i snit langs II-II i fig. 6 med spjældet drejet til sin åbenstilling.The invention will now be described in more detail in connection with some embodiments and with reference to the drawing, in which fig. 1-3 shows a sample container with pivotally mounted dampers, viewed from above, respectively, from the rear in the material passage direction and in longitudinal section along I-I in fig. 1, FIG. 4-5 sections of FIG. 3 in larger scale and showing the damper in the closed and open positions respectively; and FIG. 6-8 shows a sample container with its damper displaceable along its surface 20, seen from the side, from above, with the damper in its closing position and sectioned along II-II in FIG. 6 with the damper turned to its open position.
1 fig. 1-5 ses en prøvebeholder 2 ifølge opfindelsen, og denne har en tilførselsende 4, en fraførselsende 6, en be-25 holdervæg 8, en i en beholderoverside anbragt analyseåbning 10, et spjæld 12 til lukning og åbning af åbningen 10 eksempelvis ved hjælp af en arbejdscylinder 14, samt et opstuv-ningsmiddel.1 FIG. 1-5, a sample container 2 according to the invention is shown, which has an inlet end 4, an outlet end 6, a container wall 8, an analysis opening 10 arranged in a container top, a damper 12 for closing and opening the opening 10, for example by means of a working cylinder 14, and a dusting means.
Opstuvningsmidlet har her form af et i prøvebeholderens 30 2 materialegennemgangsretning 16 aftagende gennemgangs tværs nit, som, når materialet eksempelvis af en vibrationsføder s 18 indvirkning drives igennem beholderen, bevirker opstuvning deraf, således at det pulver-, pasta-, gele- eller kornfor-mige materiales overflade ved det lukkede spjæld 12, som vist 35 i fig.3 og 4, tager form efter dettes inderside.Here, the dusting means is in the form of a transverse riveting in the material passage direction 16 of the sample container 30 2, which, when the material is driven, for example, by the action of a vibration feeder 18, through the container, causes dusting thereof, so that the powder, paste, jelly or grain form. the surface of all the materials at the closed damper 12, as shown 35 in Figs. 3 and 4, takes shape on the inside thereof.
De organer, der sammen med materialets gennemdrivnings-middel kan danne opstuvningsmidler, kan være fysiske, d.v.s DK 170899 B1 5 at de udnytter et fysisk princip til at sikre materialets overfladedel i analyseåbningen 10 samme beliggenhed og overfladef oirm. De simpleste opstuvningsmidler er de mekaniske, og her kan nævnes på tværs af beholderens gennemgangsretning 5 indskydelige massive eller ristformige spærrevægge, udspi-lelige gennemgangshindrende spærrelegemer. Af mere specielle fysiske midler kan nævnes lokal køling, magnetisering, elektrisk feltdannelse i materialet inde i beholderen mellem dennes fraførselsende 6 og analyseåbningen 10, hvorved der f.eks 10 sker en deraf følgende forøgelse i materialets sammenhængskraft, indre friktion, viskositet etc. til lokal og kortvarig formindskelse under analysen af materialets strømmelighed, således at dette let lader sig stabilt opstuve i anlæg mod spjældets inder- eller underside.The means which together with the propellant of the material can form dusting means can be physical, i.e. they utilize a physical principle to ensure the material part of the material in the analysis opening 10 the same location and surface shape. The simplest stowage means are the mechanical ones, and here can be mentioned transverse solid or grate-shaped barrier walls, playable passage-preventing blocking elements, transverse to the passage 5 of the container. More special physical means include local cooling, magnetization, electric field formation in the material within the container between its discharge end 6 and the analysis opening 10, whereby, for example, 10 there is a consequent increase in the material's cohesiveness, internal friction, viscosity etc. to local and short-term reduction during the analysis of the flow of the material so that it can easily be stowed firmly in abutment against the inside or the underside of the damper.
15 I fig 6-8 ses en udførelsesform for prøvebeholderen, hvor dens rektangulært aftagende tværsnit er erstattet af et konisk aftagende tværsnit, og dets plane spjæld er erstattet af et konisk udformet spjæld 20. Dette kan ved en vinkeldrejning om beholderens 22 længdeakse 24 henholdsvis som vist i 20 fig. 6 og 7 afspærre analyseåbningen 26 til opstuvning af en materialeoverfladedel heri og som vist i fig. 8 blotlægge analyseåbningen 26 for analyseenheden ved at en åbning 28 i spjældet forskydes hen over den opadvendte åbning 26 i beholderen 22.FIGS. 6-8 show an embodiment of the sample container, in which its rectangular decreasing cross section is replaced by a conical decreasing cross section, and its plane damper is replaced by a conical shaped damper 20. This can be done by an angular rotation about the longitudinal axis 24 of the container 22, respectively. shown in FIG. 6 and 7 block the analyzing aperture 26 for dusting a material surface portion therein and as shown in FIG. 8 expose the analysis opening 26 of the analyzing unit by displacing an opening 28 in the damper over the upward opening 26 in the container 22.
25 Prøvebeholderen fungerer som en prøveforbereder, idet materialet, der ønskes analyseret, tilføres beholderens tilførselsende 4 og fremføres ved sin tyngde eller som vist i fig. 3 henholdsvis 6 ved hjælp af en vibrationsføder i retning mod beholderens fraførselsende 6, hvorved materialet som 30 nævnt komprimeres. Beholderens gennemgangspassage ud for analyseåbningen er ikke lodret, men har en hældning, der højst svarer til materialets stabilitets- eller skredgrænsevinkel, således at nævnte overfladedel i analyseåbningen 10,26 forbliver uændret selv om spjældet åbnes.The sample container acts as a sample preparation, the material to be analyzed being fed to the supply end 4 of the container and fed at its weight or as shown in FIG. 3 and 6, respectively, by means of a vibration feeder in the direction towards the discharge end 6 of the container, whereby the material as mentioned is compressed. The passage passage of the container next to the analysis opening is not vertical, but has a slope which corresponds at most to the stability or slant boundary angle of the material, so that said surface portion of the analysis opening 10,26 remains unchanged even if the damper is opened.
35 Spjældet åbnes først, når en passende empirisk bestemt komprimering af materialet har fundet sted. Materialet ligger derefter glat og klar til analyse gennem åbningen 10,26. Når DK 170899 B1 6 analysen eller den herfor til grund liggende måling er udført lukkes spjældet 12,20 og prøveforberederen tømmes og er klar til modtagning af næste materialeprøve eller får materialet heri ført frem til næste materialeanalysested. Ud over at ma-5 terialeprøven får en glat og ensartet præsentation i analyseåbningen, opnås også en ensartet materialetykkelse, hvilket er vigtigt ved visse optiske analysesystemer.35 The damper is opened only when an appropriate empirically determined compression of the material has taken place. The material is then smooth and ready for analysis through aperture 10.26. When the DK 170899 B1 6 analysis or the underlying measurement has been performed, the damper 12,20 closes and the sample preparation is emptied and ready to receive the next material sample or the material herein is passed to the next material analysis site. In addition to the material sample being given a smooth and uniform presentation in the assay aperture, a uniform thickness of material is also obtained, which is important in certain optical assay systems.
