Description

Die Erfindung betrifft eine Siebtrommel-Waschmaschine, mit einer in einem Gehäuse um eine waagerechte Achse drehbar angeordneten Siebtrommel sowie Führungseinrichtungen, durch die eine Warenbahn im oberen Gehäusebereich eingeleitet und nach Umlaufen der Siebtrommel abgeführt wird.The invention relates to a sieve drum washing machine with a sieve drum rotatably arranged in a housing about a horizontal axis, and guide devices through which a web of material is introduced in the upper housing region and is removed after the sieve drum has been rotated.

Zum Waschen von Bahnmaterialien, etwa zum spannungsarmen Auswaschen von Web- und Wirkwaren, werden Siebtrommel-Waschmaschinen eingesetzt, in denen das Material im Durchlaufverfahren gewaschen wird. Bei einer Ausführungsform einer bekannten Siebtrommel-Waschmaschine wird die Waschflotte aus dem Behälter durch die Warenbahn, die sich an die Siebtrommel anschmiegt, und die Siebtrommel hindurch mittels einer Pumpe in das Innere der Siebtrommel gesaugt. Die Flotte wird gefiltert und in den Trog zurückgepumpt. Bei einer anderen bekannten Ausführungsform wird die Flotte mit Hilfe einer Pumpe ebenfalls ständig umgewälzt, gefiltert und mit Spritzdüsen auf die Warenbahn aufgespritzt (EP-A1 0 280 068).Sieve drum washing machines are used for washing web materials, for example, for low-tension washing of woven and knitted goods, in which the material is washed in a continuous process. In one embodiment of a known sieve drum washing machine, the washing liquor is sucked out of the container through the web of material which conforms to the sieve drum and the sieve drum by means of a pump into the interior of the sieve drum. The fleet is filtered and pumped back into the trough. In another known embodiment, the liquor is also continuously circulated, filtered and sprayed onto the web with spray nozzles (EP-A1 0 280 068).

Die Umwälzpumpe, die Filtereinrichtung, die Spritzdüsen und das zugehörige Leitungssystem erfordern einen verhältnismäßig hohen konstruktiven Aufwand und stellen eine Störungsquelle dar. Der Energiebedarf ist verhältnismäßig hoch. Das Flottenvolumen im Trog ist groß, so daß eine große Heizleistung notwendig ist. Der Flottenaustausch ist gering, und es kommt zu einer starken Flottenanreicherung.The circulation pump, the filter device, the spray nozzles and the associated line system require a relatively high level of design effort and represent a source of interference. The energy requirement is relatively high. The liquor volume in the trough is large, so that a large heating capacity is necessary. The fleet exchange is low and there is a strong enrichment of the fleet.

Die FR-A 939 253 offenbart eine verhältnismäßig einfache Waschmaschine ohne Siebtrommel, bei der eine Warenbahn mit Hilfe eines Sternrades aus einer Anordnung aus sechs parallelen Walzen durch eine Waschlauge hindurchgeführt und dabei durch ein drehbares Flügelrad mit der Waschlauge bespritzt wird.FR-A 939 253 discloses a relatively simple washing machine without a sieve drum, in which a material web is guided through a wash liquor from an arrangement of six parallel rollers with the aid of a star wheel and is sprayed with the wash liquor by a rotatable impeller.

Die Intensität des Waschvorganges dürfte bei einer derartigen Lösung begrenzt sein.The intensity of the washing process should be limited with such a solution.

Der Erfindung liegt die Aufgabe zugrunde, eine Siebtrommel-Waschmaschine der gattungsgemäßen Art zu schaffen, deren Herstellungs- und Betriebskosten gegenüber den herkömmlichen Lösungen verringert sind.The invention has for its object to provide a screen drum washing machine of the generic type, the manufacturing and operating costs are reduced compared to the conventional solutions.

Diese Aufgabe wird bei einer Siebtrommel-Waschmaschine der obigen Art dadurch gelöst, daß die Waschmaschine in der Höhe des Flottenspiegels im Gehäuse wenigstens eine drehbare, parallel zur Siebtrommel liegende Flügelwalze zum Aufschleudern der Flotte auf die Warenbahn aufweist, und daß die Siebtrommel einen auf der Mantelfläche und an den Stirnseiten geschlossenen Zylinder umfaßt, auf dessen Umfangsfläche mit Hilfe von auf dem Zylinder befestigten, achsparallelen Stegen und einem diese einhüllenden, zylindrischen Sieb achsparallele, an den Enden offene Kanäle gebildet sind.This object is achieved in a sieve drum washing machine of the above type in that the washing machine at the level of the liquor level in the housing has at least one rotatable vane roller parallel to the sieve drum for spinning the liquor onto the web, and in that the sieve drum has one on the outer surface and includes closed cylinders on the end faces, on the circumferential surface of which axially parallel channels, which are open at the ends, are formed with the aid of axially parallel webs fastened to the cylinder and a cylindrical sieve enveloping them.

Eine Flügelwalze der hier verwendeten Art ist ein verhältnismäßig einfaches Bauteil. Sie besteht aus einem zylindrischen Kern, der parallel zur Siebtrommel angeordnet ist, und einer Anzahl von achsparallelen Flügeln auf diesem Kern, hat also etwa die Form eines Radialgebläserades. Die Flügelwalze kann mit Hilfe einer einfachen Antriebsmechanik bei geringem Energiebedarf gedreht werden.A wing roller of the type used here is a relatively simple component. It consists of a cylindrical core, which is arranged parallel to the screen drum, and a number of axially parallel blades on it Core, so roughly has the shape of a radial impeller. The wing roller can be rotated using a simple drive mechanism with low energy consumption.

Vorzugsweise umfaßt die Siebtrommel einen auf der Mantelfläche und an den Stirnseiten geschlossenen Zylinder, auf dessen Umfangsfläche mit Hilfe von auf dem Zylinder befestigten achsparallelen Stegen und einem diese einhüllenden zylindrischen Sieb achsparallele, an den Enden offene Kanäle gebildet sind.The sieve drum preferably comprises a cylinder closed on the lateral surface and on the end faces, on the circumferential surface of which axially parallel channels which are open at the ends are formed with the aid of axially parallel webs fastened to the cylinder and a cylindrical sieve enveloping them.

Bei einer derartigen Ausgestaltung der Siebtrommel tritt die Flotte, die durch die Flügelwalze auf die Warenbahn geschleudert wird, durch diese und das Sieb hindurch bis in die Kanäle, aus denen sie an den stirnseitigen Enden in den Trog zurückströmt. Die Flotte dringt jedoch nicht in das Innere des Siebtrommel-Zylinders ein, so daß dieser die Wirkung eines Verdrängerkörpers in der Flotte besitzt. Dadurch kann die Flottenmenge ganz erheblich reduziert werden, während andererseits das Material in vorteilhafter Weise von der Flotte durchströmt und damit wirksam gereinigt wird.In such a configuration of the sieve drum, the liquor which is thrown onto the material web by the wing roller passes through this and the sieve into the channels from which it flows back into the trough at the front ends. However, the liquor does not penetrate the inside of the screen drum cylinder, so that it acts as a displacer in the liquor. This allows the amount of liquor to be reduced considerably, while on the other hand the liquor advantageously flows through the material and is thus effectively cleaned.

Der Flottenspiegel wird vorzugsweise durch einen Überlauf im wesentlichen konstant gehalten. Bei einer vorteilhaften Anwendung der erfindungsgemäßen Waschmaschine werden mehrere Maschinen in Reihe aufgestellt und von der Flotte hintereinander durchströmt. Dabei werden vorzugsweise die nachfolgenden Maschinen stufenweise leicht abgesenkt, so daß die Flotte alle Maschinen über einen Zulauf und einen Überlauf kontinuierlich durchströmen kann, ohne daß eine Pumpe zu Hilfe genommen werden muß. Eine derartige Anlage wird vorzugsweise von einer Warenbahn im Gegenstrom durchlaufen, so daß das Material zunächst mit der am weitesten verschmutzten Flotte vorgewaschen und stufenweise durch die Schritt für Schritt sauberer werdende Flotte vollständig ausgewaschen wird.The fleet level is preferably kept essentially constant by an overflow. In an advantageous application of the washing machine according to the invention, several machines are set up in series and the fleet flows through them in succession. The following machines are preferably gradually lowered, so that the fleet can flow through all the machines continuously via an inlet and an overflow without the need to use a pump. Such a system is preferably passed through in countercurrent from a material web, so that the material is first prewashed with the most contaminated liquor and gradually washed out completely by the liquor, which becomes cleaner step by step.

Am Einlaß und Auslaß des Behälters können Breithaltewalzen zum Breithalten des Materials und Pendelwalzen zur Aufrechterhaltung einer kontinuierlichen Bahnspannung vorgesehen sein.At the inlet and outlet of the container, spreader rollers can be provided to hold the material wide and pendulum rollers can be used to maintain a continuous web tension.

Der von der Flotte im Behälter eingenommene Raum, im vorliegenden Zusammenhang auch als Trog bezeichnet, ist erfindungsgemäß verhältnismäßig klein gehalten. So folgt der Boden des Troges mit geringem Abstand bogenförmig der Unterseite der Siebtrommel, und zu den Seiten hin werden lediglich Erweiterungen zur Aufnahme der Flügelwalzen vorgesehen, die zweckmäßigerweise etwa bis zur Mittelachse In die Flotte eintauchen. Die Flügelwalzen drehen sich vorzugsweise auf der oberen Seite zur Siebtrommel hin, und sie sind auf der von der Siebtrommel abgewandten Seite durch Leitbleche abgeschirmt.The space occupied by the fleet in the container, also referred to in the present context as a trough, is kept relatively small according to the invention. Thus, the bottom of the trough follows the underside of the sieve drum at a short distance in an arc, and only extensions to accommodate the wing rollers are provided on the sides, which expediently plunge into the liquor approximately up to the central axis. The wing rollers preferably rotate on the upper side towards the screening drum and are shielded by baffles on the side facing away from the screening drum.

Im unteren Scheitelpunkt des Trogs kann sich eine erweiterte Kammer zur Aufnahme einer direkten oder indirekten Heizeinrichtung befinden. Unter dem Boden des Trogs können auch indirekte Heizeinrichtungen angebracht sein.In the lower apex of the trough there can be an expanded chamber for receiving a direct or indirect heating device. Indirect heating devices can also be installed under the bottom of the trough.

Im folgenden werden bevorzugte Ausführungsbeispiele der Erfindung anhand der beigefügten Zeichnung näher erläutert.

  • Die einzige Figur zeigt einen schematischen senkrechten Schnitt durch eine erfindungsgemäße Waschmaschine.
Preferred exemplary embodiments of the invention are explained in more detail below with reference to the attached drawing.
  • The single figure shows a schematic vertical section through a washing machine according to the invention.

Die Waschmaschine weist ein Gehäuse 10 auf, dessen unterer Bereich als Trog 12 ausgebildet ist. In dem Gehäuse ist eine Siebtrommel 14 angeordnet, die um eine waagerechte Achse 16 gedreht werden kann. Diese Achse 16 liegt etwa in Höhe des Spiegels einer mit 18 bezeichneten Waschflotte, die sich innerhalb des Troges 12 befindet.The washing machine has a housing 10, the lower region of which is designed as a trough 12. A sieve drum 14 is arranged in the housing and can be rotated about a horizontal axis 16. This axis 16 lies approximately at the level of a wash liquor, designated 18, which is located within the trough 12.

Die Siebtrommel 14 besteht aus einem Zylinder 20, der auf der Umfangsfläche und an den nicht gezeigten Stirnseiten vollständig geschlossen ist und auf dessen Umfangsfläche parallel zur Drehachse 16 Stege 22 befestigt sind, die die Form von radialen Lamellen aufweisen. Die Stege 22 sind durch ein Sieb 24 eingehüllt, das aus Siebdraht oder Lochblech bestehen kann. Auf diese Weise bilden sich zwischen dem Zylinder 20, den Stegen 22 und dem Sieb 24 achsparallele Kanäle 26, die an den axialen Enden offen sind. Auf diese Kanäle soll später näher eingegangen werden.The screening drum 14 consists of a cylinder 20, which is completely closed on the peripheral surface and on the end faces, not shown, and on the peripheral surface 16 webs 22 are fastened parallel to the axis of rotation 16, which have the form of radial lamellae. The webs 22 are encased by a sieve 24, which can consist of sieve wire or perforated plate. In this way, axially parallel channels 26 are formed between the cylinder 20, the webs 22 and the screen 24, which are open at the axial ends. These channels will be discussed in more detail later.

Auf beiden Seiten des Umfangs der Siebtrommel 14 befinden sich parallel zu der Siebtrommel drehbare Flügelwalzen 28,30, deren nicht bezeichnete Drehachsen im wesentlichen ebenfalls in Höhe des Spiegels der Flotte 18 liegen. Die Flügelwalzen 28,30 bestehen aus einem drehbaren Zylinder 32 und einer Anzahl von radialen, lamellenförmigen Flügeln 34 auf dessen Umfang, besitzen also etwa die Form eines Radialgebläserades. Die beiden Flügelwalzen werden mit der oberen Seite zur Siebtrommel 14 gedreht, so daß die Flotte entsprechend den nicht bezeichneten Pfeilen in der Zeichnung auf die Siebtrommel geschleudert wird. Auf der von der Siebtrommel abgewandten Seite sind die Flügelwalzen 28,30 durch Leitbleche 36,38 abgeschirmt.On both sides of the circumference of the sieve drum 14 there are rotatable wing rollers 28, 30 parallel to the sieve drum, the axes of rotation of which are not shown are also essentially at the level of the float 18. The vane rollers 28, 30 consist of a rotatable cylinder 32 and a number of radial, lamellar vanes 34 on its circumference, that is to say they have approximately the shape of a radial impeller. The two wing rollers are turned with the upper side to the screen drum 14, so that the liquor is thrown onto the screen drum in accordance with the arrows not shown in the drawing. On the side facing away from the screening drum, the wing rollers 28, 30 are shielded by baffles 36, 38.

Eine Warenbahn 40 tritt durch einen Einlaß 42 im oberen Bereich des Gehäuses 10 ein und durch einen Auslaß 44 im oberen Bereich des Gehäuses, jedoch auf der gegenüberliegenden Seite aus. Die Warenbahn läuft im Inneren des Gehäuses über Pendelwalzen 46,48 oder andere Einrichtungen zur Konstanthaltung der Bahnspannung und zwischen diesen Pendelwalzen 46,48 über etwa drei Viertel des Umfangs der Siebtrommel unten um diese herum.A web of material 40 enters through an inlet 42 in the upper region of the housing 10 and through an outlet 44 in the upper region of the housing, but on the opposite side. The material web runs inside the housing over oscillating rollers 46, 48 or other devices for keeping the web tension constant and between these oscillating rollers 46, 48 over about three quarters of the circumference of the sieve drum around it at the bottom.

Dabei wird die Waschflotte mit Hilfe der Flügelwalzen 28,30 auf die Warenbahn 40 geschleudert. Die Waschflotte durchdringt die Warenbahn und das Sieb 24 und strömt durch die Kanäle 26 zu den beiden axialen Enden der Siebtrommel und tritt hier aus. Die Warenbahn wird also im Interesse einer guten Reinigung durchströmt. Andererseits tritt die Waschflotte nicht wie bei herkömmlichen Lösungen in das Innere der Siebtrommel ein, so daß deren Zylinder 20 als Verdrängerkörper wirkt und nur eine sehr geringe Flottenmenge erforderlich ist.The wash liquor is flung onto the web 40 with the aid of the wing rollers 28, 30. The washing liquor penetrates the web and the sieve 24 and flows through the channels 26 to the two axial ends of the sieve drum and exits here. The web is therefore flowed through in the interest of good cleaning. On the other hand, the washing liquor does not enter the inside of the screening drum as in conventional solutions, so that its cylinder 20 acts as a displacer and only a very small amount of liquor is required.

Der Trog 12 folgt seinerseits mit verhältnismäßig geringem Abstand der Kontur der Unterseite der Siebtrommel 14 und der seitlichen Flügelwalzen 28 und 30. Auch dies bewirkt, daß nur eine relativ geringe Flottenmenge erforderlich ist. Im unteren Scheitelbereich des Troges 12 ist eine nach unten erweiterte Kammer 50 vorgesehen, die im übrigen auch die Funktion eines Flotten-Sumpfes hat und eine Heizschlange 52 für eine direkte Heizung oder ein Dampfeinströmrohr zur direkten Heizung der Flotte aufnimmt. Im übrigen sind an der Unterseite des Troges 12 Heizdrähte 54 oder dergleichen als indirekte Heizung vorgesehen.The trough 12 in turn follows the contour of the underside of the screen drum 14 and the side wing rollers 28 and 30 at a relatively small distance. This also means that only a relatively small amount of liquor is required. In the lower apex area of the trough 12, a chamber 50 is provided which extends downwards and which, moreover, also functions as a liquor sump and receives a heating coil 52 for direct heating or a steam inflow pipe for direct heating of the liquor. Otherwise, 12 heating wires 54 or the like are provided as indirect heating on the underside of the trough.

Auf der links in der Zeichnung gezeigten Seite befindet sich am Rande des Troges 12 ein Überlauf 56, durch den die Flotte entsprechend dem Pfeil 58 abströmt. Es wurde bereits darauf hingewiesen, daß mehrere Maschinen der dargestellten Art hintereinander geschaltet sein können und die Flotte aus dem Überlauf 56 dementsprechend in die nächste Maschine eintreten kann.On the side shown in the drawing on the left, there is an overflow 56 at the edge of the trough 12, through which the liquor flows out according to the arrow 58. It has already been pointed out that several machines of the type shown can be connected in series and the fleet from the overflow 56 can accordingly enter the next machine.

Auf der gegenüberliegenden, rechts in der Zeichnung gezeigten Seite befindet sich ein Zulauf 60 für die Waschflotte mit einem Pfeil 62, der die Strömungsrichtung anzeigt.On the opposite side, shown on the right in the drawing, there is an inlet 60 for the wash liquor with an arrow 62 which indicates the direction of flow.

Außerhalb des Gehäuses 10 sind zwei Breithaltewalzen 64,66 gezeigt, die gegenläufig zur Förderbewegung der Warenbahn gedreht werden und auf dem Umfang eine für sich bekannte Profilierung zum Breithalten des Materials aufweisen. Nachgeschaltete Quetschwerke und sonstige Einrichtungen zum Fördern der Warenbahn sind nicht gezeigt.Outside the housing 10, two spreader rollers 64, 66 are shown, which are rotated in the opposite direction to the conveying movement of the material web and have a profile, known per se, on the circumference for holding the material wide. Downstream squeezing units and other devices for conveying the web are not shown.
