Beschreibungdescription
Die Erfindung betrifft eine Vorrichtung zur Analyse von Probeflussigkeiten mit suspendierten Feststoffen nach dem Oberbegriff des Patentanspruches 1.The invention relates to a device for the analysis of sample flow with suspended solids according to the preamble of claim 1.
In der nachfolgenden Beschreibung wird als Beispiel für eine zu analysierende Probeflύssigkeit Pulpe zur Herstellung von Papier angeführt, bei der eine Polyelektrolytbestimmung durch Messung eines Strömungspotentials durchgeführt wird, wie sie beispielsweise aus der EP 0 681 180 Bl beschrieben ist. Es sei aber darauf hingewiesen, dass die Erfindung nicht hierauf alieine begrenzt ist.In the following description, an example of a sample liquid to be analyzed is pulp for the production of paper, in which a polyelectrolyte determination is carried out by measuring a flow potential, as described, for example, in EP 0 681 180 B1. It should be understood, however, that the invention is not limited thereto.
Bei der Herstellung von Papier wird eine Vielzahl von Zusatzstoffen verwendet, deren Auswirkung auf das Grundmaterial, die Pulpe, getestet werden muss. Für diese Tests sind Analysevorrichtungen, z.B. aus dem vorgenannten Dokument bekannt, die an sich Laborgeräte und darum relativ empfindlich sind. Benutzer derartiger Geräte sind in sehr vielen Fallen Beauftragte der für die Papierherstellungsindustrie tätigen Zulieferer der genannten Hilfsstoffe. Diese müssen nun zur Durchführung der Tests von Papiermacher zu Papiermacher reisen, was mit den bekannten Geräten problematisch ist.The paper industry uses a variety of additives whose impact on the base material, the pulp, has to be tested. For these tests, analyzers, e.g. known from the aforementioned document, which are in itself laboratory equipment and therefore relatively sensitive. Users of such devices are in many cases agents of the suppliers of the auxiliaries for the papermaking industry. These now have to travel from paper maker to papermaker to perform the tests, which is problematic with the known devices.
Der Erfindung liegt die Aufgabe zu Grunde, eine Vorrichtung zur Analyse der eingangs genannten Art dahin gehend aufzuzeigen, dass bei hoher Betriebssicherheit ein einfacher Transport ermöglicht wird.
Diese Aufgabe wird bei einer Vorrichtung zur Analyse von Probeflussigkeiten mit suspendierten Feststoffen, z B Pulpe, mit einer Messeinrichtung, insbesondere zur Messung eines Stromungspotentials und mit einer Titriervorrichtung zum Zufuhren einer Titnerflussigkeit aus einem Vorratsbehalter zur Probeflussigkeit dadurch gelost, dass der Vorratsbehalter zum Transport der Messeinrichtung an der Titriervorrichtung fest aber auswechselbar angebracht istThe invention is based on the object, a device for the analysis of the type mentioned in such a way to show that with high reliability, a simple transport is possible. This object is achieved in a device for the analysis of Probeflussigkeiten with suspended solids, eg pulp, with a measuring device, in particular for measuring a Stromungspotentials and with a titrator for supplying a Titnerflussigkeit from a Vorratsbehalter for Probeflussigkeit thereby solved that the Vorratsbehalter for transporting the measuring device attached to the titration but fixed interchangeable
Ein wesentlicher Punkt der Erfindung hegt also darin, dass der Vorratsbehalter für die Titnerflussigkeit an der Titriervorrichtung beim Transport angebracht bleibt. Man hat also keinerlei Problem damit, dass ein größerer Vorratsbehalter immer wieder abgenommen, neu verschlossen und auch die Titriervorrichtung von der Titnerflussigkeit befreit und gesäubert werden muss, bevor man das ganze Gerat überhaupt einpacken kann Weiterhin bleibt gemäß der Erfindung sichergestellt, dass die Titnerflussigkeit durch das Abnehmend des Vorratsbehalters nicht verschüttet oder kontaminiert werden kann. Auch der Verlust an Titnerflussigkeit wird somit sehr gering gehalten Der Begriff „fest angebracht" gilt also auch z B für eine Schlauchverbindung, die wahrend des Transportes ungeöffnet bleibtAn essential point of the invention thus consists in the fact that the storage container for the Titnerflussigkeit remains attached to the titration device during transport. So you have no problem with it that a larger Vorratsbehalter removed again, re-sealed and the titration of the Titnerflussigkeit must be cleaned and cleaned before you can even pack the whole device Furthermore, it remains ensured according to the invention that the Titnerflussigkeit by the Dipping the Vorratsbehalters can not be spilled or contaminated. The loss of Titnerflussigkeit is thus kept very low The term "firmly attached" so also applies, for example, for a hose connection, which remains unopened during transport
Vorzugsweise umfasst die Titriervorrichtung eine elektrisch betatigbare Pumpeinrichtung, die in stromlosem Zustand einen zum Vorratsbehalter fuhrenden Ansaugkanal verschließt Es sind somit keine gesonderten Mittel oder Maßnahmen notwendig, um einen Transport frei von Flussigkeitsverlust zu gewahrleistenPreferably, the titration device comprises an electrically operable pumping device, which closes in the de-energized state leading to the Vorratsbehalter intake channel There are thus no separate means or measures necessary to ensure a transport free of Flussigkeitsverlust
Die Pumpeinrichtung umfasst vorzugsweise eine Membranpumpe. Derartige Pumpen sind äußerst robust und darum auch sehr einfach zu transportierenThe pumping device preferably comprises a diaphragm pump. Such pumps are extremely robust and therefore also very easy to transport
Die Pumpeinrichtung umfasst vorzugsweise eine Basisplatte, in welcher der Ansaugkanal, vorzugsweise zusätzlich auch mindestens Abschnitte eines Ausstromkanales ausgebildet sind Dadurch wird erreicht, dass ein äußerst geringes Flussigkeitsvolumen ohne die Gefahr, Luft mit anzusaugen, zwischen dem direkt an der Basisplatte angebrachten Voriatsbehaltei und der Pumpeinrichtung voihegt, was wiedeium zu sehi geringen
Flussigkeitsverlusten beim Verbrauch des Inhalts des Vorratsbehalters fuhrt. Darüber hinaus ist der Aufbau äußerst stabilThe pumping device preferably comprises a base plate in which the suction channel, preferably in addition also at least portions of a discharge channel are formed. This ensures that an extremely small liquid volume without the risk of sucking air, between the directly attached to the base plate Voriatsbehaltei and the pumping device voihed , what a reminder to see little Fluid losses when consuming the contents of Vorratsbehalters leads. In addition, the structure is extremely stable
Vorzugsweise ist die Titriervorrichtung mit der Messeinrichtung wahrend einer Messung fest verbindbar. Durch diesen Aufbau ist ein korrektes Arbeiten kurze Zeit nach einem Auspacken der Analysevorrichtung möglichPreferably, the titration device can be firmly connected to the measuring device during a measurement. By this construction, a correct operation is possible a short time after unpacking the analyzing apparatus
Die Titriervorrichtung weist vorzugsweise eine Steuervorrichtung auf, welche bei einem festen Verbinden der Titriervorrichtung mit der Messeinrichtung mit einerThe titration device preferably has a control device, which in a fixed connection of the titration device with the measuring device with a
Steuerelektronik der Messeinrichtung in elektrische Verbindung gebracht wird.

This device comprises a measuring device 10 which has a movable piston 11 which is moved up and down in a measuring vessel 12. The resulting stiction potential is tapped ubei a voltage measuring device 13 and a Stuireelektionik 14 for Evaluation transmitted During the measurement 20 Titπerflussigkeit known Molaπtat from a Vorratsbehalter 21 via a pump 22 and a supply line 28 is added to the Probenflussigkeit via a titration device The measurement is terminated when the measured Stromungspotential is lowered to zero The result, ie the amount of added Titπerflussigkeit or a corresponding metrological equivalent is displayed on a display 16
Der Vorratsbehalter 21 weist eine Identifikationseinrichtung 31 auf, über welche der Vorratsbehalter 21 mittels einer an der Messeinrichtung 10 angebrachten Leseeinrichtung 15 identifiziert werden kann, welche ein entsprechendes Identifikationssignal an die Steuerelektronik 14 übermitteltThe Vorratsbehalter 21 has an identification device 31, via which the Vorratsbehalter 21 can be identified by means of a mounted on the measuring device 10 reading device 15, which transmits a corresponding identification signal to the control electronics 14
Die Titriervorrichtung 20 ist über eine Steuereinrichtung 30 an der Messeinrichtung 10 wahrend der Messung fest aber ansonsten abnehmbar angebracht Die Steuereinrichtung 30 übernimmt die elektrische Verbindung zwischen der Pumpe 22 und der Steuerung 14, wobei alle elektrischen Verbindungen der Übersichtlichkeit halber in Fig 1 symbolisch als „offene Leitungen" gezeigt sindThe titration device 20 is attached via a control device 30 to the measuring device 10 during the measurement fixed but otherwise removable. The controller 30 assumes the electrical connection between the pump 22 and the controller 14, all electrical connections for clarity in Figure 1 symbolically as "open Lines "are shown
Die in Fig 2 gezeigte Ausfuhrungsform der Erfindung unterscheidet sich von der nach Fig 1 lediglich dadurch, dass der Vorratsbehalter 21 in einer anderen Art und Weise (nämlich nach oben ragend) an der Titriervorrichtung 20 angebracht ist Die übrigen soeben beschriebenen Bauteile wurden der besseren Übersichtlichkeit halbei fortgelassenThe embodiment of the invention shown in FIG. 2 differs from that according to FIG. 1 only in that the storage container 21 is attached to the titration device 20 in a different manner (namely, protruding upward). The other components just described have been described for the sake of clarity omitted
Die an der Messeinrichtung 10 abnehmbar oder fest angebrachte Titriervorrichtung weist, wie dies in Fig 3 naher gezeigt ist, eine Basisplatte 23 auf, an welcher der Vorratsbehalter 21 z B mittels einer Schraubverbindung derart angebracht ist, dass Titneiflussigkeit aus dem Vorratsbehalter 21 in einen Ansaugkanal 24 angesaugt werden kann, der in der Basisplatte 23 angebracht ist Der Ansaugkanal 24 fuhrt über ein Ventil 29 an die Unterseite einer Membian 26, die mittels eines Antriebs 25 auf und ab bewegbar ist In stromlosem Zustand liegt die Membran 26 auf dem Ende der Ansaugleitung 24 auf und dichtet diese somit (im genannten stromlosen Zustand) ab
In der Basisplatte 23 ist weiterhin ein Ausstromkanal 27 derart angebracht, dass von dei Membran 26 durch das Ruckschlagventil 29 angesaugte Titπerflussigkeit über ein zweites Ruckschlagventil 29' und den Ausstromkanal 27 in die Zuleitung 28 (und von dort wahrend der Messung m das Messgefaß 12) gefordert werden kannAs shown in more detail in FIG. 3, the titration device detachably or permanently attached to the measuring device 10 has a base plate 23 to which the storage container 21 z B is attached by means of a screw connection such that titanium liquid flows from the storage container 21 into an intake channel 24 The suction channel 24 leads via a valve 29 to the underside of a diaphragm 26, which is movable up and down by means of a drive 25. In the de-energized state, the diaphragm 26 rests on the end of the suction line 24 and thus seals them (in said currentless state) In the base plate 23, an outflow channel 27 is further mounted such that from the membrane 26 sucked by the check valve 29 Titπerflussigkeit via a second check valve 29 'and the outflow channel 27 into the supply line 28 (and from there during the measurement m the measuring vessel 12) required can be
