Abstract

The method involves providing a drum with a set of discontinuously closable discharge openings (3) for feeding through discrete drains of the drum. The discrete drains of the drum are monitored and/or controlled by a measuring and control unit (4) based on speed of the drum. The speed of the drum is detected by the measuring and control unit using magnetic or optical sensors. A piston valve (5) is provided for feeding through of the drains through the openings. The openings are closed during the discharge after falling below a predetermined speed. An independent claim is also included for a device for separation or purification of material of mixtures in a centrifugal field of a rotating drum of a centrifuge.

Description

Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruchs 1 und eine Vorrichtung nach dem Oberbegriff des Anspruchs 7.The invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 7.

Ein gattungsgemäßes Verfahren stellt die DE 44 14 602 A1 dar, in welcher ein Verfahren zur Steuerung einer diskontinuierlich arbeitenden Zentrifuge offenbart wird. Bei diesem Verfahren wird die Feststoffentleerung durch die Messung der Ablagerungsschichtdicke berührungsfrei mittels einer Sonde vermessen. Anschließend können diese Werte zusammen mit den Ausräumungswerten der Füllmassen verglichen und durch ein externes Prozessleitsystem ausgewertet. Dieses Verfahren hat den Nachteil, dass es nur für bestimmte Produkte, beispielsweise für die Abtrennung von Zucker realisierbar ist.A generic method provides the DE 44 14 602 A1 in which a method for controlling a discontinuous centrifuge is disclosed. In this method, the solids discharge is measured by the measurement of the deposition layer thickness without contact by means of a probe. Subsequently, these values can be compared with the removal values of the filling compounds and evaluated by an external process control system. This method has the disadvantage that it can only be realized for certain products, for example for the separation of sugar.

Es ist aus dem Stand der Technik ferner bekannt, dass die diskontinuierliche Entleerung über die Überwachung und/oder Steuerung der Stromstärkenschwankung während der Entleerung realisierbar ist.It is also known from the prior art that the discontinuous emptying via the monitoring and / or control of the current fluctuation during emptying is feasible.

Dieses Verfahren der Messung von Stromstärkeänderungen hat insbesonders bei relativ großen Separatoren (Getränken, Milch) den Nachteil, dass es durch Flüssigkeiten im Steuerkreislauf und Haubenspülwasser im stärkeren Maße beeinflusst wird. In Folge wurden stark schwankende Werte des Stromhubs trotz optimaler Entleerung festgestellt.This method of measuring changes in current intensity has the disadvantage, in particular with relatively large separators (beverages, milk), that it is influenced to a greater extent by liquids in the control circuit and hood rinse water. As a result, strongly fluctuating values of the current lift were detected despite optimal emptying.

Die Erfindung setzt angesichts der Probleme ausgehend von der DE 44 14 602 A1 bei der Aufgabe an, eine verbesserte Überwachung und/oder Steuerung sowie eine vereinfachte Handhabung der Automatisierung der Feststoffentleerung in diskontinuierlichen Trennprozessen zu schaffen.The invention is based on the problems starting from the DE 44 14 602 A1 in the task to provide improved monitoring and / or control and simplified handling of the automation of solids discharge in discontinuous separation processes.

Die Erfindung löst diese Aufgabe durch die Merkmale der Ansprüche 1 und 7.The invention solves this problem by the features of claims 1 and 7.

Dabei zeigt die Überwachung und/oder Steuerung anhand der Drehzahlüberwachung des Motors eine deutliche Vereinfachung gegenüber der DE 44 14 602 A1 , da produkt-unabhängig eine optimierte Automatisierung dieser Trennabläufe anbietet.The monitoring and / or control based on the speed monitoring of the engine shows a significant simplification compared to the DE 44 14 602 A1 because product-independent offers optimized automation of these separation processes.

Eine Drehzahländerung charakterisiert eine Masse, die dem System entzogen wird. Zunächst werden die Stoffkomponenten mit der höheren Dichte, beispielsweise Feststoffteilchen, unter Einfluss einer Massenträgheit nach außen getragen und über eine diskontinuierlich verschließbare Austragsöffnung abgeführt.A speed change characterizes a mass that is extracted from the system. First, the substance components with the higher density, for example solid particles, are carried to the outside under the influence of an inertia and removed via a discontinuously closable discharge opening.

Es ist bekannt, die Regelung der Entleerung über eine diskontinuierlich verschließbare Austragsöffnung mittels eines Kolbenschiebers zu gewährleisten. Dieser kann zum Beispiel über einen hydraulischen Steuerkreislauf durch eine Mess- und Steuereinheit direkt angesteuert werden. Die Dosierung der Hydraulikflüssigkeit als auch anderer Komponenten, wie beispielsweise das Haubenspülwasser, bewirkt bei der Drehzahlmessung, aufgrund der relativen Trägheit der Trommelmasse deutlich geringere Schwankungen gegenüber der Messung der Stromstärke. Dadurch ist eine sehr exakte Kontrolle und Einflussname auf die Entleerung möglich.It is known to ensure the control of the emptying via a discontinuously closable discharge opening by means of a piston valve. This can be controlled directly via a hydraulic control circuit by a measuring and control unit, for example. The metering of the hydraulic fluid as well as other components, such as the hood rinsing water causes in the speed measurement, due to the relative inertia of the drum mass significantly lower fluctuations compared to the measurement of the current. This allows a very precise control and influence name on the emptying.

Die Messung der Drehzahl kann zum Beispiel durch Sensoren erfolgen. So sind unter anderem induktive Sensoren oder photoelektrische Sensoren je nach Belastungsobergrenze des Motors einsetzbar.The measurement of the speed can be done for example by sensors. For example, inductive sensors or photoelectric sensors can be used depending on the upper load limit of the motor.

Bevorzugt seien hier die magnetischen Sensoren genannt.Preferably, the magnetic sensors may be mentioned here.

Somit ist durch eine gezielte Änderung der Messparameter, d.h. Auswertung der Drehzahl der Trommel anstelle der Stromstärke des Motors oder anstelle der Ablagerungsschichtdicke an der Innenseite der Trommel eine bessere Kontrolle des Gesamtprozesses gegeben.Thus, by a targeted change of the measurement parameters, i. Evaluation of the rotational speed of the drum instead of the current strength of the motor or instead of the deposition layer thickness on the inside of the drum given a better control of the overall process.

Weitere vorteilhafte Anwendungsmöglichkeiten der exakten Steuerung über das Drehzahlsignal ergeben sich durch Kopplung mit SC (spill control) - Separatoren.Further advantageous applications of the exact control over the speed signal are obtained by coupling with SC (spill control) separators.

Anspruch 2 beschreibt darüber hinaus eine bevorzugte Methode zur Drehzahlüberwachungen. Magnetische und optische Sensoren sind in der Regel kostengünstig und in der Großproduktion einsetzbar. Eine vorteilhafte Methode ist das Anbringen von Magneten an der Trommel und die Messung der veränderlichen Feldstärke durch die Relativbewegung eines Dauermagneten.Claim 2 also describes a preferred method for speed monitoring. Magnetic and optical sensors are generally inexpensive and can be used in large-scale production. An advantageous method is the attachment of magnets to the drum and the measurement of the variable field strength by the relative movement of a permanent magnet.

Dadurch unterliegt die Messung nur noch geringen Schwankungen durch zusätzliche Parameter (Vorfüllwasser und Haubenspülwasser). Die findet vor allem bei Separatoren größerer Art, wie sie in der Milch oder Getränkeverarbeitung zum Einsatz kommen, eine Anwendung.As a result, the measurement is only subject to slight fluctuations due to additional parameters (pre-fill water and hood rinse water). This is mainly used for separators of a larger type, such as those used in milk or beverage processing, for use.

Nach Anspruch 3 erfolgt die Entleerung durch einen Kolbenschieber, welcher mittels eines Steuerventils durch die Mess- und Steuereinheit angesteuert werden kann. Diese vorteilhafte Ausgestaltung der Trommel mit einem Kolbenschieber vermindert das Risiko des Verstopfens der Auslasskanäle im Vergleich zu anderen Auslassregel-systemen.According to claim 3, the emptying takes place by a piston valve, which can be controlled by a control valve by the measuring and control unit. This advantageous embodiment of the drum with a piston valve reduces the risk of clogging of the outlet channels compared to other outlet control systems.

Ein Ausführungsbeispiel der Erfindung wird anhand der beigefügten Zeichnungen erläutert. Es zeigt:

Figur 1
den Querschnitt eines schematisch dargestellten Separators, im diskontinuierlichen Betrieb; und
Figur 2
eine schematische Darstellung eines motorbetriebenen Separators.
An embodiment of the invention will be explained with reference to the accompanying drawings. It shows:
FIG. 1

FIG. 2

Nach dem Beispiel der Fig. 1 ist der Querschnitt eines Tellerseparators mit einer Trommel 1 dargestellt, welche sich bei Betrieb um ein Rotationszentrum dreht. Dabei wird die Drehzahländerung wie auch die Betriebsdrehzahl der Trommel von einem Mess- und Steuersensor 4 erfasst, welcher direkt oder indirekt das Auslasssystem zur diskontinuierlichen Entleerung, bestehend aus einem Kolbenschieber 5 und einer Austragsöffnung 3, ansteuert.After the example of Fig. 1 the cross section of a Tellerseparators is shown with a drum 1, which rotates in operation about a center of rotation. The speed change as well as the operating speed of the drum is detected by a measuring and control sensor 4, which directly or indirectly the discharge system for discontinuous emptying, consisting of a spool 5 and a discharge opening 3, controls.

Zudem ist durch den Kolbenschieber 5 mit Hilfe eines Steuerventils 6 und Hydraulikflüssigkeit 10 die diskontinuierliche Stoffentleerung über die Mess- und Steuereinheit geregelt. Es ist vorteilhaft, die Entleerung der flüssigen Stoffkomponenten mit Hilfe mindestens eines Greifers 11 zu gewährleisten.In addition, by the spool 5 with the aid of a control valve 6 and hydraulic fluid 10, the discontinuous emptying of the measuring and control unit regulated. It is advantageous to ensure the emptying of the liquid substance components by means of at least one gripper 11.

Bei einer fest-flüssig Trennung ist zudem eine Abscheidevorrichtung 12 bekannt, beispielsweise in Form des dargestellten Tellerseparators, welche zudem durch einen Feststoffsammelraum 13 ergänzt wird.In the case of a solid-liquid separation, a separating device 12 is also known, for example in the form of the illustrated plate separator, which is also supplemented by a solids collecting space 13.

Vorzugsweise soll das Steuerventil 6 mit Hilfe einer Steuereinheit 4 bedient werden, welche auf veränderte Drehzahlen der Trommel reagiert.Preferably, the control valve 6 should be operated by means of a control unit 4, which responds to changing speeds of the drum.

In der Darstellung der Fig. 2 ist die Trommel 14 eines Separators über eine Spindel 7 mittels eines Riemenantriebs 8 mit einem Motor 9 verbunden und angetrieben. Der Zulauf 15 eines fest-flüssig Stoffgemisches erfolgt am Kopfteil des Separators, ebenso wie der Ablauf 16 der Flüssigphase. Der abgetrennte Feststoff wird über eine Austragsöffnung 17 seitlich an der Trommel ausgeführt.In the presentation of the Fig. 2 the drum 14 of a separator is connected and driven via a spindle 7 by means of a belt drive 8 to a motor 9. The feed 15 of a solid-liquid mixture of substances takes place at the top of the separator, as well as the drain 16 of the liquid phase. The separated solid is carried out via a discharge opening 17 laterally on the drum.

Mögliche Regelungsbereiche sollen in folgendem Beispiel dargestellt werden: Ereignis: Drehzahl bei der Entleerung fällt um 100 U/min Merkmal: Die Entleerung ist zu klein Folge: Bei der nächsten Entleerung wird die Zeit für das Vorfüllwasser verringert Ereignis: Drehzahl bei der Entleerung fällt um 150 U/min Merkmal: Die Entleerung hat den Sollwert erreicht Folge: keine Aktion Ereignis: Drehzahl bei der Entleerung fällt um 200 U/min Merkmal: Die Entleerung ist zu groß Folge: Bei der nächsten Entleerung wird die Zeit für das Vorfüllwasser erhöht Possible control ranges are shown in the following example: Event: Discharge speed drops by 100 rpm Feature: The emptying is too small Episode: At the next draining, the time for the pre-fill water is reduced Event: Discharge speed drops by 150 rpm Feature: The emptying has reached the setpoint Episode: no action Event: Discharge speed falls by 200 rpm Feature: The emptying is too big Episode: At the next draining, the time for the pre-fill water is increased
