Description
Vorrichtung zum Messen der Preßdrücke an Walzenpressen für Briketts Die Erfindung betrifft eine Vorrichtung zum unmittelbaren und fortlaufenden Messen des Preßdruckes in einzelnen Brikettforrnen von Walzenpressen für Briketts, insbesondere Steinkohlenbriketts.Device for measuring the pressing pressures on roller presses for briquettes The invention relates to a device for direct and continuous measurement of the pressing pressure in individual briquette forms of roller presses for briquettes, in particular Hard coal briquettes.
Zur Herstellung einwandfreier Briketts ist die Einhaltung eines bestimmten Preßdrucks Voraussetzung. In order to produce flawless briquettes, compliance with a certain Press pressure requirement.
Bei Verwendung von Walzenpressen ist die absolute Höhe dieses Druckes bisher nicht bekannt. Die Einstellung des Druckes erfolgt empirisch nach Beschaffenheit der Brikettoberfläche. Die Güte der Briketts ist also weitgehend von der Eignung und der Aufmerksamkeit des Pressenführers abhängig.When using roller presses, this is the absolute level of this pressure not known so far. The pressure is set empirically according to its nature the briquette surface. The quality of the briquettes is therefore largely dependent on suitability and the attention of the press operator.
Es sind Meßvorrichtungen bekannt, die den Lagerdruck der Preßwalzen messen. Diese Meßvorrichtungen geben nur beschränkt auswertbare Ergebnisse, weil die Drücke der Stege zwischen den einzelnen Brikettformen in die Messung eingehen. Ferner können diese Meßwerte nur eine Aussage über den mittleren Druck über die Walzenbreite ermöglichen. There are measuring devices known that the bearing pressure of the press rolls measure up. These measuring devices give only limited evaluable results because the pressures of the webs between the individual briquette forms are included in the measurement. Furthermore, these measured values can only provide information about the mean pressure via the Enable roll width.
Es wurde festgestellt, daß in der Regel beträchtliche Druckunterschiede über die Walzenbreite bestehen.It was found that there are usually considerable pressure differences exist across the width of the roll.
Die Erfindung ermöglicht die Messung des absoluten Preßdruckes in einzelnen Brikettformen in verschiedenen Formreihen und weiterhin die selbsttätige fortlaufende Regelung des Preßdrucks. Erfindungsgemäß sind in die Walzen kraftschlüssig mit einer oder mehreren Brikettformen verbundene Druckmeßdosen eingebaut, deren Meßwerte durch die Antriebswelle auf Anzeigegeräte übertragen werden. Mit Vorzug sind die Meßstellen über die Walzenbreite und gegebenenfalls über den Walzenumfang gleichmäßig verteilt. Durch die Anordnung mehrerer Meßstellen auf der Walze, deren Meßwerte einzeln angezeigt werden, kann die Verteilung der absoluten Preßdrücke überwacht werden. Der Pressenführer hat also die Möglichkeit, an einzelnen Stellen festgestellte Unregelmäßigkeiten zu beheben, ohne die übrigen Stellen zu beeinflussen. An Stelle der Druckmeßdosen können auch andere Meßwertgeber benutzt werden, z. B. Dehnungsstreifen. The invention enables the measurement of the absolute pressing pressure in individual briquette forms in various series of forms and the automatic one continuous regulation of the baling pressure. According to the invention, the rollers are frictionally engaged built-in pressure cells connected to one or more briquette forms, their Measured values are transmitted to display devices through the drive shaft. With preference are the measuring points across the roll width and possibly over the roll circumference equally distributed. By arranging several measuring points on the roller, whose Measured values are displayed individually, the distribution of the absolute pressing pressures be monitored. The press operator thus has the option of working at individual points to remedy any irregularities found without affecting the other bodies. Instead of the pressure cells, other transducers can also be used, e.g. B. Stretch marks.
Bei einer bevorzugten Ausführungsform tragen die Druckmeßdosen senkrecht zur Walzenoberfläche Stempel, deren druckaufnehmende Fläche gleichzeitig Bestandteil der Brikettform ist. Durch den Stempel, in dessen freies Ende der Scheitelteil der Brikettform eingearbeitet ist, ist die Brikettform geschlossen. Der Preßdruck wird unmittelbar auf die Druckmeßdose übertragen. In a preferred embodiment, the pressure cells carry vertically to the roller surface stamp, the pressure-absorbing surface of which is also a component which is briquette form. Through the stamp, in the free end of which the apex part of the Briquette form is incorporated, the briquette form is closed. The pressing pressure is transferred directly to the pressure cell.
Ebenso ist es möglich, die zu messende Brikettform als Ganzes im Stempel auszusparen. Der Oberteil des Stempels stellt also eine Formhälfte dar. Bei dieser Ausführungsform wird der Preßdruck über die ganze Formfläche gemessen. It is also possible to measure the briquette shape as a whole in To leave out stamps. The upper part of the stamp therefore represents one half of the mold. at In this embodiment, the pressing pressure is measured over the entire mold surface.
Mit Hilfe vom Meßvorrichtungen gemäß der Erfindung kann nun der Preßdruck fortlaufend in an sich bekannter Weise gesteuert werden. Bei einem Verfahren erfolgt die Steuerung über die Füllung. With the help of the measuring devices according to the invention, the pressing pressure continuously controlled in a manner known per se. In one proceeding takes place control over the filling.
Die Meßwerte der Druckmeßdosen werden zur selbsttätigen Regelung der Füllung der Brikettformen benutzt. Bei einem anderen Verfahren dienen sie zur selbsttätigen Regelung der Lagerdrücke, und zwar unterschiedlich für die beiden Walzenlager. Über die Walzenbreite verschiedene Drücke können damit ausgeglichen werden.The measured values of the pressure cells are used to automatically control the Used to fill the briquette molds. In another method, they are used for automatic Regulation of the bearing pressures, differently for the two roller bearings. Above The different pressures of the roller width can thus be compensated for.
Abb. 1 ist ein Längsschnitt durch eine Preßwalze mit einer Meßvorrichtung gemäß der Erfindung, Abb. 2 ein Ausschnitt nach Abb. 1 in größerem Maßstab, in dem der Einbau einer Meßdose dargestellt ist. Fig. 1 is a longitudinal section through a press roll with a measuring device according to the invention, Fig. 2 is a section according to Fig. 1 on a larger scale, in which the installation of a load cell is shown.
Auf der Antriebswelle 1 der Preßwalze sitzt der Gußkörper2, auf den der Mantel3 aufgeschrumpft ist. In diesen sind die Brikettformen 4 eingefräst. In den Gußkörper 2 ist die Druckmeßdose 5 eingebaut, deren Stempel 6 im Mantel 3 geführt ist. Die druckaufnehmende Fläche des Stempels 6 ist Bestandteil der Brikettform 4. In der Druckmeßdose 5 werden die Druckwerte in proportionale elektrische Spannungen umgewandelt. Diese werden durch die Leitungen 7 durch die Antriebswelle 1 auf einen Schleifringkörper 8 geführt, durch Schleifringe abgenommen und einer hier nicht dargestellten Stromquelle und dem Anzeigegerät zugeführt. On the drive shaft 1 of the press roll sits the cast body 2 on the the jacket3 is shrunk on. The briquette forms 4 are milled into these. In The cast body 2 is built into the pressure cell 5, the stamp 6 of which is guided in the jacket 3 is. The pressure-absorbing surface of the stamp 6 is part of the briquette form 4. In the pressure cell 5, the pressure values are converted into proportional electrical voltages converted. These are through the lines 7 through the drive shaft 1 on a Slip ring assembly 8 out, removed by slip rings and one not here power source shown and supplied to the display device.
