Description

Die Erfindung betrifft einen Magnetabscheider nach dem Oberbegriff des ersten Patentanspruchs.The invention relates to a magnetic separator according to the preamble of the first patent claim.

In den Prozessen der Getränke- und Lebensmittelindustrie sowie der Pharmazie und Biotechnologie wird ein Magnetabscheider verwendet, um magnetische und/oder magnetisierbare Partikel, beispielsweise Metallspäne, aus dem in sich Verarbeitung befindenden Fluid zu entfernen.In the processes of the beverage and food industries as well as pharmaceuticals and biotechnology, a magnetic separator is used to remove magnetic and/or magnetizable particles, such as metal chips, from the fluid being processed.

Der Magnetabscheider besitzt ein durchströmbares Gefäß, in welchem ein Magnetfeld erzeugt ist. Mit diesem Magnetfeld werden magnetische und/oder magnetisierbare Partikel aus dem Fluid auf Teilen der Gefäßwandung abgeschieden. Vorzugsweise wird wenigstens ein Dauermagnet verwendet, der in einem Topf angeordnet ist, welcher in den Innenraum des Gefäßes ragt und dort vom Fluid umströmt wird. Auf diesem Topf lagern sich nun magnetische und/oder magnetisierbare Partikel ab. Nach und nach bildet sich auf der dem Innenraum ausgesetzten Wandung des Topfes eine Schicht.The magnetic separator has a vessel that can be flowed through and in which a magnetic field is generated. With this magnetic field, magnetic and/or magnetizable particles are deposited from the fluid onto parts of the vessel wall. Preferably, at least one permanent magnet is used, which is arranged in a pot which projects into the interior of the vessel and the fluid flows around it there. Magnetic and/or magnetizable particles are now deposited on this pot. A layer gradually forms on the wall of the pot exposed to the interior.

In einem Wartungsvorgang muss der Magnetabscheider geöffnet werden, um die angelagerten magnetischen und/oder magnetisierbaren Partikel zu entfernen. Nach der Reinigung wird der Magnetabscheider wieder verschlossen und der Prozess kann erneut gestartet und betrieben werden, bis erneut die angelagerten Partikel so zahlreich sind, dass eine Reinigung erforderlich ist.During a maintenance procedure, the magnetic separator must be opened in order to remove the attached magnetic and/or magnetizable particles. After cleaning, the magnetic separator is closed again and the process can be started and operated again until the accumulated particles are so numerous that cleaning is required.

US 5,043,063 zeigt einen Magnetabscheider aus einem Hohlkörper, der eine offene Oberseite und einen abnehmbaren Deckel aufweist. Am dem Deckel ist eine Platte gelagert, und längliche, beabstandete nichtmagnetische Rohre befestigt. An der Platte sind längliche Magnetstapel befestigt, die sich durch den Deckel in die Rohre erstrecken. Zum Entfernen von magnetischem Material aus den Rohren, kann der Deckel vom Gehäuse abgenommen und die Magnetstapel aus den nichtmagnetischen Rohren mit der Platte herausgezogen werden, sodass sich das Magnetfeld innerhalb der Rohre abbaut und magnetisches Material herabfällt. US 5,043,063 shows a magnetic separator made of a hollow body that has an open top and a removable lid. A plate is mounted on the lid and elongated, spaced non-magnetic tubes are attached. Elongated magnet stacks are attached to the plate and extend through the lid into the tubes. To remove magnetic material from the tubes, the cover can be removed from the housing and the magnet stacks can be pulled out of the non-magnetic tubes with the plate so that the magnetic field inside the tubes is reduced and magnetic material falls down.

Da Prozessunterbrechungen Kosten durch Stillstand verursachen, sollten sie so selten und so kurz wie möglich sein.Since process interruptions cause costs due to downtime, they should be as rare and as short as possible.

Es war daher Aufgabe der Erfindung, einen Magnetabscheider mit verbesserten Wartungseigenschaften vorzustellen.It was therefore the object of the invention to present a magnetic separator with improved maintenance properties.

Diese Aufgabe wird gelöst durch einen Magnetabscheider mit den Merkmalen des Anspruchs 1. Die abhängigen Ansprüche 2 bis 10 geben vorteilhafte Weiterbildungen des Magnetabscheiders an.This task is solved by a magnetic separator with the features of claim 1. The dependent claims 2 to 10 specify advantageous developments of the magnetic separator.

Der Magnetabscheider umfasst ein Gehäuse, welches einen Innenraum, einen Anschluss und einen Flansch aufweist. Ein Deckel steht mit dem Flansch in einer lösbaren Verbindung und weist einen in den Innenraum einbringbaren Topf auf. Der Magnetabscheider besitzt eine Magnetanordnung, die einen in den Topf einbringbaren Dauermagneten umfasst. Es ist vorgesehen, dass der Magnetabscheider ein bewegbares Sperrelement zur Festlegung des in den Topf eingebrachten Dauermagneten umfasst, welches durch die Verbindung von Deckel und Flansch mit der Magnetanordnung in Formschluss gebracht ist. In dieser Gestaltung des Magnetabscheiders ist der Dauermagnet nur dann in einer Position im Topf festgelegt, wenn die Magnetanordnung mit dem Gehäuse verbunden ist. Dies ist insbesondere während des Betriebs im Prozess der Fall. Bei der Wartung ist die Magnetanordnung nicht mehr mit dem Gehäuse verbunden. Dann kann der Dauermagnet aus dem Topf entnommen werden, wodurch das Magnetfeld am Topf geschwächt oder ganz entfernt wird und die Reinigung des Topfes deutlich leichter fällt und mithin schneller verläuft. Gleichzeitig wird verhindert, dass der Dauermagnet im Prozess aus dem Topf entfernt wird und die Partikel ungewollt frei in den Innenraum des Gehäuses gelangen.The magnetic separator includes a housing which has an interior, a connection and a flange. A lid is in a detachable connection with the flange and has a pot that can be inserted into the interior. The magnetic separator has a magnet arrangement that includes a permanent magnet that can be inserted into the pot. It is envisaged that the magnetic separator comprises a movable locking element for fixing the permanent magnet introduced into the pot, which is brought into positive locking with the magnet arrangement by the connection of the cover and flange. In this design of the magnetic separator, the permanent magnet is only fixed in a position in the pot when the magnet arrangement is connected to the housing. This is particularly the case during operation in the process. During maintenance, the magnet assembly is no longer connected to the housing. The permanent magnet can then be removed from the pot, whereby the magnetic field on the pot is weakened or completely removed and cleaning the pot is much easier and therefore faster. At the same time, it prevents the permanent magnet from being removed from the pot during the process and the particles from unintentionally getting into the interior of the housing.

In einer kostengünstigen Ausführung ist vorgesehen, dass das Sperrelement am Deckel angeordnet ist.In a cost-effective embodiment it is provided that the locking element is arranged on the lid.

Herstellung und Konstruktion des Magnetabscheiders sind vereinfacht, wenn das Sperrelement linear bewegbar ist.Manufacturing and construction of the magnetic separator are simplified if the blocking element is linearly movable.

Die Bedienung des Magnetabscheiders während der Wartung wird in einer Weiterbildung erleichtert, indem ein Rückstellelement vorgesehen ist und das Sperrelement gegen eine Rückstellkraft des Rückstellelements in formschlüssigen Eingriff gebracht ist.The operation of the magnetic separator during maintenance is made easier in a further development in that a restoring element is provided and the locking element is brought into positive engagement against a restoring force of the restoring element.

Eine andere Weiterbildung verbessert ebenfalls die Bedienbarkeit des Magnetabscheiders. Es ist ein Steuerelement vorgesehen, mit welchem eine Bewegung des Dauermagneten an eine Verschiebung des Sperrelements gekoppelt ist. Das Steuerelement kann an einem von Sperrelement oder Magnetanordnung angebracht sein. Die Kopplung bewirkt, dass der Dauermagnet erst dann aus dem Topf entnehmbar ist, wenn Deckel und Flansch voneinander getrennt sind. Dies verhindert ein versehentliches Entnehmen des Dauermagnetes im betriebsbereiten Zustand des Magnetabscheiders. Kontamination der Produkts wird durch die Weiterbildung somit verhindert.Another development also improves the operability of the magnetic separator. A control element is provided with which a movement of the permanent magnet is coupled to a displacement of the locking element. The control element can be attached to one of the locking elements or magnet arrangements. The coupling means that the permanent magnet can only be removed from the pot when the lid and flange are separated from each other. This prevents the permanent magnet from being accidentally removed when it is ready for use Condition of the magnetic separator. Contamination of the product is thus prevented by further training.

Gemäß einer einfachen Ausführungsform dieser Weiterbildung ist vorgesehen, dass das Sperrelement eine Steuerplatte umfasst und die Steuerplatte eine Nut aufweist, in welcher ein Stift der Magnetanordnung aufgenommen ist und welche schräg zu einer Bewegungsrichtung der Magnetanordnung verläuft. Stift und Nut erzeugen eine leicht herstellbare und sicher funktionierende Kopplung.According to a simple embodiment of this development, it is provided that the locking element comprises a control plate and the control plate has a groove in which a pin of the magnet arrangement is received and which runs obliquely to a direction of movement of the magnet arrangement. Pin and groove create an easy-to-produce and reliably functioning coupling.

Der Magnetabscheider ist in seiner Wirkung durch eine vergrößerte magnetisch aktive Oberfläche verbessert und gleichzeitig eine leicht herstellbare Kopplung geschaffen, wenn die Magnetanordnung wenigstens zwei Dauermagnete umfasst, jeder der Dauermagnete in einen eigenen Topf einbringbar ist und eine Halterung aufweist und der Stift zwei Halterungen miteinander verbindet.The effect of the magnetic separator is improved by an enlarged magnetically active surface and at the same time an easily producible coupling is created if the magnet arrangement comprises at least two permanent magnets, each of the permanent magnets can be inserted into its own pot and has a holder and the pin connects two holders together.

Gemäß einer anderen Weiterbildung ist vorgesehen, dass auf einer dem Topf abgewandten Seite des Deckels der Topf durch einen Rohrfortsatz fortgesetzt ist. Diese wirkt als Schutz und Führung für den Dauermagneten.According to another development, it is provided that the pot is continued by a tubular extension on a side of the lid facing away from the pot. This acts as protection and guidance for the permanent magnet.

Eine andere Weiterbildung verbessert die Wartungseigenschaften, indem auf einer dem Topf abgewandten Seite des Deckels eine Schutzhülle vorgesehen ist, in welche der Dauermagnet einbringbar ist, und welche eine Abschirmung des Magnetfeldes bewirkend ausgeführt ist. Hierdurch wird verhindert, dass magnetische und/oder magnetisierbare Partikel sich am Dauermagneten anlagern, während sich dieser nicht im Topf befindet.Another development improves the maintenance properties by providing a protective cover on a side of the lid facing away from the pot, into which the permanent magnet can be inserted and which is designed to shield the magnetic field. This prevents magnetic and/or magnetizable particles from attaching to the permanent magnet while it is not in the pot.

Diese Weiterbildung wird zusätzlich verbessert, indem die Schutzhülle eine Haube umfasst, so dass der Dauermagnet rundum geschützt ist, während er sich nicht im Topf befindet.This development is further improved in that the protective cover includes a hood so that the permanent magnet is completely protected while it is not in the pot.

Anhand von Ausführungsbeispielen und deren Weiterbildungen sollen die Erfindung näher erläutert und die Darstellung der Wirkungen und Vorteile vertieft werden.Using exemplary embodiments and their further developments, the invention will be explained in more detail and the presentation of the effects and advantages will be deepened.

Ein am Gehäuse 1 vorgesehener Anschluss 3 ist mit einer Prozessanlage verbindbar ausgeführt und mit dem Innenraum 2 fluidverbunden. Vorzugsweise sind wenigstens zwei Anschlüsse vorgesehen und für die Durchströmbarkeit des Magnetabscheiders ausgelegt. Am Gehäuse 1 ist ein Flansch 4 zur Aufnahme eines Deckels 5 ausgeformt. Am Flansch kann ein Dichtungssitz 6 ausgebildet sein, der mit einer Dichtung 7 zusammenwirkt, die am Deckel 5 angeordnet sein kann.The magnetic separator has a housing 1, which has an interior 2. A connection 3 provided on the housing 1 is designed to be connectable to a process system and is fluidly connected to the interior 2.

Am Deckel 5 ist ein Topf 8 vorgesehen, der in den Innenraum 2 des Magnetabscheiders ragt und von Prozessfluid umströmbar ausgeführt ist. In ein Inneres des Topfes 8 ist ein Dauermagnet 9 einbringbar, dessen Magnetfeld sich in den Innenraum 2 des Magnetabscheiders erstreckt und dort magnetische sowie magnetisierbare Partikel anzieht. Diese lagern sich auf einer dem Innenraum 2 zugewandten Oberfläche 10 des Topfes 8 ab. In einer vorteilhaften Weiterbildung sind mehrere Töpfe vorgesehen, in die jeweils Dauermagneten einbringbar sind. Hierdurch wird das Verhältnis aus Magnetmaterial und Oberfläche verbessert. Es steht mehr von einem Magnetfeld durchdrungene Oberfläche zur Verfügung, auf der sich die magnetischen und/oder magnetisierbaren Partikel ablagern.A pot 8 is provided on the lid 5, which projects into the interior 2 of the magnetic separator and is designed so that process fluid can flow around it. A permanent magnet 9 can be inserted into the interior of the pot 8, the magnetic field of which extends into the interior 2 of the magnetic separator and attracts magnetic and magnetizable particles there. These are deposited on a surface 10 of the pot 8 facing the interior 2. In an advantageous development, several pots are provided, into which permanent magnets can each be inserted. This improves the ratio of magnetic material to surface. There is more surface permeated by a magnetic field available on which the magnetic and/or magnetizable particles are deposited.

Der Dauermagnet 9 ist an einer Magnetanordnung 11 angebracht. Die Magnetanordnung 11 haltert den Dauermagneten 9 und bewirkt eine Positionierung innerhalb des Topfes 8.The permanent magnet 9 is attached to a magnet arrangement 11. The magnet arrangement 11 holds the permanent magnet 9 and effects positioning within the pot 8.

Die Magnetanordnung 11 kann bewegbar ausgeführt sein, insbesondere geradlinig entlang einer ersten Achse A verschiebbar. Durch Bewegung der Magnetanordnung 11 ist der Dauermagnet 9 in den Topf 8 einbringbar oder aus diesem entnehmbar. Eine Entnahme des Dauermagneten 9 ist bei der Reinigung des Magnetabscheiders von Vorteil, da das Magnetfeld am Topf 8 geschwächt oder ganz beseitigt wird und die angelagerten Partikel leichter von der Oberfläche 10 entfernt werden können.The magnet arrangement 11 can be designed to be movable, in particular displaceable in a straight line along a first axis A. By moving the magnet arrangement 11, the permanent magnet 9 can be inserted into the pot 8 or removed from it. Removing the permanent magnet 9 is advantageous when cleaning the magnetic separator, since the magnetic field on the pot 8 is weakened or completely eliminated and the attached particles can be removed more easily from the surface 10.

Die Magnetanordnung 11 kann eine Stange 12 umfassen, an deren dem Topf 8 zugewandten Ende der Dauermagnet 9 befestigt ist. Die Stange 12 durchsetzt ein Loch 13, welches im Deckel 5 vorgesehen ist. Ein freier Durchmesser des Loches 13 ist so bemessen, dass der Dauermagneten 9 durch das Loch hindurch bewegbar ist. Die Stange 12 ist in einem Stangenlager 14 beweglich gelagert, welches Stangenlager 14 in einer am Deckel 5 befestigten Halterung 15 aufgenommen ist.The magnet arrangement 11 can comprise a rod 12, at the end facing the pot 8 the permanent magnet 9 is attached. The rod 12 passes through a hole 13 which is provided in the cover 5. A free diameter of the hole 13 is dimensioned such that the permanent magnet 9 can be moved through the hole. The rod 12 is movably mounted in a rod bearing 14, which rod bearing 14 is accommodated in a holder 15 attached to the cover 5.

An einem dem Dauermagneten 9 abgewandten Ende der Stange12 kann ein Handgriff 16 vorgesehen sein, mit dem der Dauermagnet 9 handbetätigt aus dem Topf 8 heraus bewegt und in ihn eingebracht werden kann. Diese vorteilhaft kostengünstige und baulich einfache Ausführung kann alternativ durch eine pneumatische, elektrische oder hydraulische Betätigungsvorrichtung ersetzt oder ergänzt sein.At an end of the rod 12 facing away from the permanent magnet 9, a handle 16 can be provided, with which the permanent magnet 9 can be manually moved out of the pot 8 and inserted into it. This advantageously inexpensive and structurally simple design can alternatively be replaced or supplemented by a pneumatic, electrical or hydraulic actuation device.

Am Deckel 5 ist ein Sperrelement 17 angeordnet. Dieses umfasst einen stangenförmigen Schieber 18 der in einem Lagerblock 19 von einem Schieberlager 20 entlang einer zweiten Achse L verschiebbar gelagert ist.A locking element 17 is arranged on the lid 5. This includes a rod-shaped slide 18 which is mounted in a bearing block 19 by a slide bearing 20 so that it can move along a second axis L.

Die Fig. 1 zeigt einen betriebsbereiten Zustand des Magnetabscheiders, in welchem der Deckel 5 auf dem Flansch 4 ruht und der Innenraum 2 geschlossen ist. Ein erstes Schieberende 21 des Schiebers 18 berührt den Flansch 4. Ein zweites Schieberende 22 bildet mit der Magnetanordnung 11 einen Formschluss, indem es eine Sperrscheibe 23 derart überlappt, dass die Bewegung der Magnetanordnung 11 entlang der ersten Achse A verhindert ist. Auf diese Weise ist das bewegbare Sperrelement 17 zur Festlegung des in den Topf 8 eingebrachten Dauermagneten durch die Verbindung von Deckel 5 und Flansch 4 mit der Magnetanordnung 11 in einen Formschluss gebracht.The Fig. 1 shows an operational state of the magnetic separator, in which the cover 5 rests on the flange 4 and the interior 2 is closed. A first slide end 21 of the slide 18 touches the flange 4. A second slide end 22 forms a positive connection with the magnet arrangement 11 by overlapping a locking disk 23 in such a way that the movement of the magnet arrangement 11 along the first axis A is prevented. In this way, the movable locking element 17 for fixing the permanent magnet introduced into the pot 8 is brought into a positive fit by connecting the cover 5 and flange 4 to the magnet arrangement 11.

Wenn der Deckel 5 vom Flansch 4 abgenommen wird, ist der Formschluss zwischen Sperrelement 17 und Magnetanordnung 11 lösbar und die Magnetanordnung entlang der ersten Achse A verschiebbar. Insbesondere ist dann der Dauermagnet 9 aus dem Topf 8 entnehmbar.When the cover 5 is removed from the flange 4, the positive connection between the locking element 17 and the magnet arrangement 11 can be released and the magnet arrangement can be moved along the first axis A. In particular, the permanent magnet 9 can then be removed from the pot 8.

Gemäß einer Weiterbildung ist am Sperrelement 17 eine Vorspanneinrichtung vorgesehen. Diese umfasst im Beispiel eine am stangenförmigen Schieber 18 angeordnete Druckscheibe 24. Zwischen dieser und dem Lagerblock 19 ist ein im Beispiel als Spiralfeder ausgebildetes Rückstellelement 25 angeordnet. Das Rückstellelement 25 ist so ausgebildet, dass es mechanisch gespannt ist, wenn Deckel 5 und Flansch 4 miteinander verbunden sind, und bei Lösen der Verbindung von Flansch 4 und Deckel 5 diese Spannung zu einer Bewegung des Sperrelement 17 führt, welche den Formschluss zwischen Sperrelement 17 und Magnetanordnung 11 aufhebt. Die Druckscheibe 24 kann alternativ als Absatz auf dem stangenförmigen Schieber 18 ausgebildet sein.According to a further development, a biasing device is provided on the locking element 17. In the example, this includes a pressure washer 24 arranged on the rod-shaped slide 18. Between this and the bearing block 19 there is an im For example, a restoring element 25 designed as a spiral spring is arranged. The restoring element 25 is designed in such a way that it is mechanically tensioned when the cover 5 and flange 4 are connected to one another, and when the connection between the flange 4 and cover 5 is loosened, this tension leads to a movement of the locking element 17, which ensures the positive connection between the locking element 17 and magnet arrangement 11 cancels. The pressure washer 24 can alternatively be designed as a shoulder on the rod-shaped slide 18.

Eine andere mögliche Weiterbildung sieht vor, dass auf einer dem Topf 8 abgewandten Seite des Deckels 5 eine Schutzhülle 26 vorgesehen ist, in welche der Dauermagnet 9 einbringbar ist, und welche eine Abschirmung des Magnetfeldes bewirkend ausgeführt ist. Diese Abschirmung kann entweder durch ein geeignetes Material für die Schutzhülle 26 bewirkt werden, beispielsweise magnetundurchlässiges Metall (MU-Metall). Alternativ und kostengünstiger ist es, wenn die Abschirmung durch Abstand erreicht wird, d.h. die Schutzhülle 26 den Dauermagneten 9 in einem so großen Abstand umgibt, dass keine nennenswerte Anlagerung größerer Partikel erfolgt. Insbesondere wird die Beeinflussung von Werkzeug, beispielsweise Schraubendrehern, verhindert.Another possible development provides that a protective cover 26 is provided on a side of the lid 5 facing away from the pot 8, into which the permanent magnet 9 can be inserted and which is designed to shield the magnetic field. This shielding can be achieved either by a suitable material for the protective cover 26, for example magneto-impermeable metal (MU metal). Alternatively and more cost-effectively, it is if the shielding is achieved by spacing, i.e. the protective cover 26 surrounds the permanent magnet 9 at such a large distance that no significant accumulation of larger particles occurs. In particular, the influence of tools, such as screwdrivers, is prevented.

Die Schutzhülle 26 kann als Haube ausgeführt sein, so dass auf der dem Topf 8 abgewandten Seite des Deckels 5 die Schutzhülle 26 den Dauermagneten 9 vollständig umschließt.The protective cover 26 can be designed as a hood, so that on the side of the lid 5 facing away from the pot 8, the protective cover 26 completely encloses the permanent magnet 9.

Die Fig. 2 zeigt den Magnetabscheider der ersten Ausführungsform in einer Weiterbildung.The Fig. 2 shows the magnetic separator of the first embodiment in a further development.

Der erste Teil der Weiterbildung betrifft Ausführung und Zusammenspiel von Sperrelement und Magnetanordnung.The first part of the further training concerns the design and interaction of the locking element and magnet arrangement.

Das Sperrelement 17' umfasst als ein Steuerelement eine Steuerplatte 27, welche mit dem Schieber 18' verbunden ist, beispielsweise mit Hilfe einer Stiftverbindung 28, die vorzugsweise nur ein geringes Spiel aufweist. Die Steuerplatte besitzt eine Nut 29, in welcher ein Stift 30 aufgenommen ist, welcher an der Magnetanordnung 11 angebracht ist. Die Nut 29 erstreckt in einer Längsrichtung R. Eine Weite der Nut 29 und ein Durchmesser des Stifts 30 sind aufeinander abgestimmt, damit der Stift 30 der Längsrichtung R folgend in der Nut 29 bewegbar ist. Die Längsrichtung R ist gegen die erste Achse A, entlang welcher die Magnetanordnung 11 bewegbar ist, gekippt. Eine Bewegung der Magnetanordnung 11 und ihres Stifts 30 bewirkt daher eine Bewegung der Steuerplatte 27 quer zur Bewegungsrichtung der Magnetanordnung 11. Aufgrund der Stiftverbindung 28 folgt der Schieber 18' dieser Querbewegung und führt eine Bewegung entlang der zweiten Achse L aus. Die Längsrichtung R der Nut 29 ist so ausgerichtet, dass eine Bewegung der Magnetanordnung 11, die der Entnahme des Dauermagneten aus dem Topf 8 entspricht, eine Bewegung des Schiebers 18' bewirkt, welche eine Montage des Deckels 5 am Flansch 4 verhindert. Insbesondere wird eine Montage verhindert, bei der Dichtung 7 und Dichtungssitz 6 in dichtenden Kontakt gelangen. Auf diese Weise wird sehr zuverlässig vermieden, dass ein nicht betriebsbereiter Magnetabscheider, bei dem sich der Dauermagnet 9 nicht im Topf 8 befindet und daher keine Partikel auf der Oberfläche 10 des Topfes 8 festlegen kann, in Betrieb gesetzt wird. Sobald die Magnetanordnung 11 bewegt wird, um den Dauermagneten 9 wieder in den Topf 8 einzubringen, wird der Schieber 18' in eine Stellung gebracht, in welcher der Deckel 5 mit dem Flansch 4 verbindbar ist und Dichtung 7 und Dichtungssitz 6 in Berührung kommen.The locking element 17 'comprises as a control element a control plate 27, which is connected to the slide 18', for example with the aid of a pin connection 28, which preferably has only a small amount of play. The control plate has a groove 29 in which a pin 30 is received, which is attached to the magnet arrangement 11. The groove 29 extends in a longitudinal direction R. A width of the groove 29 and a diameter of the pin 30 are coordinated with one another so that the pin 30 can be moved in the groove 29 following the longitudinal direction R. The longitudinal direction is R tilted against the first axis A, along which the magnet arrangement 11 is movable. A movement of the magnet arrangement 11 and its pin 30 therefore causes a movement of the control plate 27 transversely to the direction of movement of the magnet arrangement 11. Due to the pin connection 28, the slide 18 'follows this transverse movement and carries out a movement along the second axis L. The longitudinal direction R of the groove 29 is aligned such that a movement of the magnet arrangement 11, which corresponds to the removal of the permanent magnet from the pot 8, causes a movement of the slide 18 ', which prevents the cover 5 from being mounted on the flange 4. In particular, an assembly in which seal 7 and seal seat 6 come into sealing contact is prevented. In this way, it is very reliably avoided that a non-operational magnetic separator, in which the permanent magnet 9 is not in the pot 8 and therefore cannot fix any particles on the surface 10 of the pot 8, is put into operation. As soon as the magnet arrangement 11 is moved in order to reinsert the permanent magnet 9 into the pot 8, the slide 18 'is brought into a position in which the cover 5 can be connected to the flange 4 and the seal 7 and seal seat 6 come into contact.

Vorteilhaft ist es, die Verkippung der Nut 29 gegen die erste Achse A und die Kraft des Rückstellelements 25 so aufeinander abzustimmen, dass das Rückstellelement 25 keine Bewegung der Magnetanordnung 11 entlang der ersten Achse A bewirkt. Die Kopplung durch die Steuerplatte 27 ist dann selbstgehemmt.It is advantageous to coordinate the tilting of the groove 29 against the first axis A and the force of the restoring element 25 so that the restoring element 25 does not cause any movement of the magnet arrangement 11 along the first axis A. The coupling through the control plate 27 is then self-locked.

Der zweite Teil der Weiterbildung betrifft den Topf. Es ist vorteilhaft, den Topf 8 auf einer dem Topf 8 abgewandten Seite des Deckels 5 mit einem Rohrfortsatz 31 weiterzuführen. Die Erstreckung des Rohrfortsatzes 31 oberhalb des Deckels 5 ist derart bemessen, dass er dem Dauermagneten 9 Schutz bietet, wenn dieser aus dem Topf 8 entnommen ist. Zusätzlich kann der Rohrfortsatz 31 eine Führung der Magnetanordnung 11 bewirkend ausgeführt sein.The second part of the further training concerns the pot. It is advantageous to continue the pot 8 with a tubular extension 31 on a side of the lid 5 facing away from the pot 8. The extent of the tubular extension 31 above the lid 5 is dimensioned such that it offers the permanent magnet 9 protection when it is removed from the pot 8. In addition, the tubular extension 31 can be designed to guide the magnet arrangement 11.

Die Schutzhülle 26' kann einen Fuß 32 umfassen, welcher am Deckel 5 befestigt und mit dem Flansch 4 verbindbar ist. Eine Klammer 33 umfasst Fuß 32 und Flansch 4 und schafft eine lösbare Verbindung von Deckel 5 und Flansch 4. Im Fuß 32 kann ein zweites Schieberlager 34 vorgesehen sein, welches einen Abstand zum Schieberlager 20 aufweist und die Führung des Schiebers 18' verbessert.The protective cover 26 'can include a foot 32, which is attached to the cover 5 and connectable to the flange 4. A clamp 33 includes foot 32 and flange 4 and creates a detachable connection between cover 5 and flange 4. A second slide bearing 34 can be provided in foot 32, which is at a distance from the slide bearing 20 and improves the guidance of the slide 18 '.

In Fig. 3 ist eine andere Weiterbildung des Beispiels eines Magnetabscheiders gezeigt.In Fig. 3 Another development of the example of a magnetic separator is shown.

In dieser Weiterbildung umfasst die Magnetanordnung ein Oberteil 35, welches als eine Platte ausgeführt sein kann, die im Wesentlichen parallel zum Deckel 5 angeordnet ist. Das Oberteil 35 weist einen in einer radialen Richtung außen liegenden Rand 36 auf, der im betriebsbereiten Zustand des Magnetabscheiders auf dem Flansch 4 aufliegt. Auf einer dem Deckel 5 zugewandten Seite des Oberteils 35 ist ein in Richtung des Deckels 5 weisender Vorsprung 37 vorgesehen.In this development, the magnet arrangement comprises an upper part 35, which can be designed as a plate which is arranged essentially parallel to the cover 5. The upper part 35 has an edge 36 lying on the outside in a radial direction, which rests on the flange 4 when the magnetic separator is in the operational state. On a side of the upper part 35 facing the lid 5, a projection 37 pointing in the direction of the lid 5 is provided.

In dem Vorsprung 37 ist eine Aufnahme 38 zur Aufnahme des stangenförmigen Schiebers 18 im betriebsbereiten Zustand des Magnetabscheiders vorgesehen, die beispielsweise vorteilhaft einfach als Bohrung ausgeführt ist.A receptacle 38 is provided in the projection 37 for receiving the rod-shaped slide 18 in the operational state of the magnetic separator, which is advantageously designed simply as a bore, for example.

Deckel 5 und Oberteil 35 sind zum lösbaren Verbinden miteinander eingerichtet. Beispielsweise kann der Deckel 5 einen Gewindestift 39 aufweisen, welcher im betriebsbereiten Zustand des Magnetabscheiders das Oberteil 35 durchsetzt und eine Mutter 40 zur Sicherung der Verbindung von Deckel 5 und Oberteil 35 trägt.Lid 5 and upper part 35 are designed to be detachably connected to one another. For example, the cover 5 can have a set screw 39, which passes through the upper part 35 when the magnetic separator is ready for operation and carries a nut 40 to secure the connection of the cover 5 and the upper part 35.

Zur Wartung des Magnetabscheiders, insbesondere Reinigung der Oberfläche 10, wird zunächst die miteinander verbundenen Deckel 5 und Oberteil 35 vom Flansch 4 abgehoben. Das Rückstellelement 25 bewirkt eine Verschiebung des Schiebers 18 entlang der zweiten Achse L derart, dass er aus der Aufnahme 38 entfernt wird. Dadurch kann das Oberteil 35 vom Deckel 5 abgehoben werden. Der mit dem Oberteil mechanisch verbundene Dauermagnet 9 wird beim Abheben aus dem Topf 8 entnommen. Durch die Entnahme wird die Reinigung der Oberfläche 10 erheblich erleichtert. Vorteilhaft gewährleistet dieser Aufbau, dass der Dauermagnet 9 nur dann aus dem Topf 8 entnommen werden kann, wenn der Magnetabscheider offensichtlich aus dem betriebsfertigen Zustand in einen nicht betriebsbereiten Zustand überführt wird, in welchem Deckel 5 und Oberteil 35 nicht mehr mit dem Gehäuse 1 verbunden sind.To maintain the magnetic separator, in particular cleaning the surface 10, the interconnected cover 5 and upper part 35 are first lifted off the flange 4. The restoring element 25 causes a displacement of the slide 18 along the second axis L such that it is removed from the receptacle 38. This allows the upper part 35 to be lifted off the lid 5. The permanent magnet 9, which is mechanically connected to the upper part, is removed from the pot 8 when it is lifted. The removal makes cleaning the surface 10 considerably easier. This structure advantageously ensures that the permanent magnet 9 can only be removed from the pot 8 when the magnetic separator is obviously transferred from the operational state to a non-operational state, in which the cover 5 and upper part 35 are no longer connected to the housing 1 .

Der Zusammenbau nach der Reinigung wird vereinfacht, wenn eine Innenwand 41, die dem Schieber 18 zugewandt ist, einen in Richtung des Innenraums 2 sich verjüngenden Trichterabschnitt bildet, so dass der Schieber 18 auf einer Schrägen gleitet und radial nach Innen in Richtung Dauermagnet geschoben wird.Assembly after cleaning is simplified if an inner wall 41, which faces the slide 18, forms a funnel section that tapers towards the interior 2, so that the slide 18 slides on an incline and is pushed radially inwards towards the permanent magnet.

Auch dieser Magnetabscheider kann durch ein Steuerelement verbessert werden. Beispielsweise kann diese nach dem an Fig. 2 dargestellten Prinzip den Abstand von Oberteil 35 und Deckel 5 an die radiale Position des Schiebers 18 koppeln. Dies vereinfacht den Zusammenbau und verhindert Fehlbedienung.This magnetic separator can also be improved with a control element. For example, this can be done after an Fig. 2 The principle shown couples the distance between the upper part 35 and the cover 5 to the radial position of the slide 18. This simplifies assembly and prevents incorrect operation.
