Abstract
Description
Die Erfindung betrifft einen Pulper mit einem Siebblech, einem darüber angeordneten Rührer, einem ersten Ablauf oberhalb des Siebblechs und einem Ablauf unterhalb des Siebblechs. Darüber hinaus betrifft die Erfindung unterschiedliche Verfahren zur Verwendung eines derartigen Pulpers.The The invention relates to a pulper with a screen plate, one arranged above stirrer, a first drain above the screen plate and a drain below of the screen plate. About that In addition, the invention relates to different methods of use such a pulper.
Derartige Pulper werden zur Aufbereitung von Papierreststoffen, biologischen Materialien und einer Vielzahl weiterer Stoffe verwendet. Hierbei werden die Stoffe einem Mahlvorgang unterzogen und es werden verschiedene Fraktionen getrennt. Die Trennung der Fraktionen geschieht einerseits durch die Anordnung der Abläufe und andererseits die Ausbildung und Anordnung des Siebbleches.such Pulpers are used for the treatment of paper residues, biological Materials and a variety of other substances used. in this connection The substances are subjected to a grinding process and there are different Fractions separately. The separation of the fractions happens on the one hand through the arrangement of the processes and on the other hand, the design and arrangement of the screen plate.
Derartige Pulper sind in verschiedensten Ausführungsformen seit vielen Jahren im Einsatz und sie haben sich gut bewährt.such Pulpers are in many different embodiments for many years in action and they have worked well.
Der Erfindung liegt die Aufgabe zugrunde derartige Pulper weiterzuentwickeln und Verfahren zur Verwendung eines derartigen Pulpers bereitzustellen.Of the Invention is the object of further developing such pulpers and to provide methods of using such a pulper.
Diese Aufgabe wird dadurch gelöst, dass oberhalb des Siebbleches Kugeln angeordnet sind, deren Durchmesser größer als die Löcher des Siebblechs ist.These Task is solved by that above the screen plate balls are arranged, whose diameter greater than the holes of the screen plate is.
Die Anordnung von Kugeln oberhalb des Siebbleches führt dazu, dass diese Kugeln die Prozesse im Pulper beschleunigen. Die Kugeln haben hierbei zum Teil die Funktion einer Kugelmühle. Je nach Auswahl von Größe, Gewicht und Material der Kugeln führen die Kugeln jedoch zu weiteren positiven Ergebnissen während der Behandlung von Reststoffen im Pulper.The Arrangement of balls above the screen plate causes these balls accelerate the processes in the pulper. The balls have this to Part of the function of a ball mill. Depending on the selection of size, weight and lead material of the balls the bullets, however, lead to further positive results during the Treatment of residues in the pulper.
Obwohl das Prinzip der Kugelmühle seit langem bekannt ist, wurden im Pulper bisher keine Kugeln eingesetzt, da davon ausgegangen wird, dass derartige Kugeln im Mahlprozess zerstört werden oder negative Auswirkungen auf die Vorgänge im Pulper haben.Even though the principle of the ball mill has long been known, in the pulper so far no balls were used, since it is assumed that such balls in the grinding process destroyed or have a negative impact on the operations in the pulper.
Erfreulicherweise hat sich herausgestellt, dass der Einsatz von Kugeln im Pulper die Abläufe deutlich beschleunigt und die Kugeln dadurch einen positiven Einfluss auf den Prozess im Pulper haben.Fortunately, It has been found that the use of balls in the pulper Procedures clearly accelerates and thereby the balls on a positive influence have the process in the pulper.
Damit die Kugeln nicht im Pulper aufschwimmen, sollten sie eine spezifische Dichte haben, die über 1 liegt. Für spezielle Anwendungen kann die spezifische Dichte unter 1 liegen, da die Kugeln mit dem Rührer auch entgegen ihrem Auftrieb in das Mahlgut hinein gefördert werden können.In order to the balls do not float in the pulper, they should have a specific Have density over 1 lies. For special applications, the specific gravity may be below 1, because the balls with the stirrer be promoted against their buoyancy in the millbase into it can.
Besonders gute Ergebnisse konnten erzielt werden, wenn die Kugeln eine spezifische Dichte von unter 2,0 haben. Zu schwere Kugeln können das Siebblech beschädigen und sie können durch Abrieb einen negativen Einfluss auf die Prozesse im Pulper haben.Especially good results could be achieved if the balls have a specific Have density of less than 2.0. Too heavy balls can damage the screen plate and you can by abrasion have a negative impact on the processes in the pulper.
Besonders gute Ergebnisse wurden mit Kugeln mit einer spezifischen Dichte zwischen 1,3 und 1,8 erzielt. Beispielsweise eignen sich Kugeln aus PVC mit einem spezifischen Gewicht von etwa 1,4 besonders gut für die Prozesse im Pulper.Especially good results were obtained with spheres with a specific density between 1.3 and 1.8. For example, balls are suitable made of PVC with a specific gravity of about 1.4 especially good for the Processes in the pulper.
Die Kugeln können eine sphärische Oberfläche aufweisen. Je nach Anwendungsfall kann die Oberfläche aber von einer sphärischen Form abweichen und die Kugeln können sogar eine eckige Oberfläche aufweisen.The Balls can a spherical one surface exhibit. Depending on the application, the surface can however from a spherical one Diverge shape and the balls can even a square surface exhibit.
Besonders gute Ergebnisse konnten mit einem Pulper erzielt werden, der einen unter Überdruck setzbaren geschlossenen Raum aufweist. Dies ermöglicht es oberhalb der Flüssigkeitsoberfläche im Pulper ein Luftpolster mit einem Überdruck von 0,1 bis 0,5 bar, wie beispielsweise von 0,2 bar einzusetzen.Especially good results could be achieved with a pulper, the one under overpressure has settable closed space. This allows it above the liquid surface in the pulper an air cushion with an overpressure from 0.1 to 0.5 bar, such as 0.2 bar use.
Um einen derartigen Überdruck im Pulper zu erzeugen, wird vorgeschlagen, dass der Pulper ein bis zu einem Niveau befüllbares Pulpergefäß aufweist und sich Zulauf und Ablauf in einem Bereich oberhalb dieses Niveaus erstrecken. Dadurch kann die Flüssigkeitssäule im Zulauf und im Ablauf dazu dienen, einen Überdruck im Pulper bereitzustellen. Durch eine Variation der Höhe von Zulauf und Ablauf kann somit auf einfache Art und Weise der Druck im Pulper variiert werden. Insbesondere für den Einsatz des Pulpers als Drucksortierer wird vorgeschlagen, dass das Siebblech Löcher mit einer Fläche von der Größe einer Kreisfläche von 0,1 bis 0,5 mm aufweist.Around such overpressure in the pulper, it is proposed that the pulper one to fillable to a level Pulpergefäß having and inlet and outlet in an area above this level extend. As a result, the liquid column in the inlet and serve in the process to provide an overpressure in the pulper. By a variation of height of inlet and outlet can thus easily Pressure in the pulper can be varied. In particular for the use of the pulper as Pressure sorter is suggested that the screen plate holes with a surface the size of one circular area from 0.1 to 0.5 mm.
Aus konstruktiven Gründen ist es vorteilhaft, wenn das Siebblech ein planes Lochblech aufweist. Der Pulper kann dadurch zum Entstippen, Malen und Sortieren verwendet werden.Out constructive reasons It is advantageous if the screen plate has a flat perforated plate. Of the Pulper can thereby be used for de-staining, painting and sorting become.
Je nach Einsatzbereich ist es vorteilhaft, wenn das Lochblech Schlitze aufweist. Hierbei können im Bereich des Einsatzes von Pulper üblicherweise verwendete Schlitzbleche eingesetzt werden. Beispielsweise eignen sich Schlitze mit einer Breite von 0,1 bis 0,2 mm und einer Länge von einem bis mehreren Zentimetern.ever According to application, it is advantageous if the perforated plate slots having. Here you can slotted sheets commonly used in the field of pulper application be used. For example, slots are suitable with a Width of 0.1 to 0.2 mm and a length of one to several Centimeters.
Die Aufgabe der Erfindung wird auch mit einer Verwendung eines derartigen Pulper gelöst, bei der im Pulper mit den Kugeln und dem Rührer Schnipsel und Begleitstoffe behandelt werden, in einem Hydrozyklon die Kugeln abgetrennt werden und die Kugeln in den Pulper zurückgeführt werden.The The object of the invention is also with a use of such Pulper solved, in the pulper with the balls and the stirrer, snippets and accompanying substances be treated in a hydrocyclone, the balls are separated and the balls are returned to the pulper.
Hierbei ist es besonders vorteilhaft, wenn im Hydrozyklon eine Gegenstromwäsche durchgeführt wird.in this connection it is particularly advantageous if countercurrent washing is carried out in the hydrocyclone.
Dieses Verfahren wird vorzugsweise kontinuierlich betrieben, um eine effektive schnelle Behandlung zu ermöglichen.This Process is preferably operated continuously to provide an effective to allow fast treatment.
Der Pulper eignet sich besonders auch als Entstipper und als Defibrillator.Of the Pulper is particularly suitable as a deflaker and as a defibrillator.
