Abstract

Raw wool contains very many dirty substances and additionally has to be cleaned of the animal fat. The wool should not become matted during washing. There are known machines in which the flow passes through the wool fleece in stages on screening drums and the wool fleece subsequently floats freely. The dirt is then precipitated in the floating zones. To collect the dirty substances, a funnel-shaped discharge space is provided underneath a perforated bottom which delimits the treatment space. The dirty substances often accumulate on the bottom, which is necessary in order to prevent fibre loss, and clog the perforation holes. In order to avoid stopping the machine so as to clean it, care is taken to ensure that, between the perforated bottom (8) and the screening drums (3-5) and also in the region of the floating zones (9), a parallel flow (20, 21) of the liquid occurs over the entire length of the bath (1), in that the liquid circulated in the bath is supplied only at the inlet (18) of the bath and, by lowering the outflow edge (22) at the end of the bath and placing the press (24-27) at a lower level, a larger quantity of liquid flows out in the direction of transport of the fleece (10). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Vorrichtung wie sie im Oberbegriff des ersten Patentanspruchs definiert ist. Eine Vorrichtung dieser Art ist aus der DE 23 57 055 A1 bekannt.The invention relates to a device as defined in the preamble of the first claim. A device of this type is known from DE 23 57 055 A1.

Rohwollwaschmaschinen dieser Art haben sich in der Praxis vielfach bewährt. Ihr Vorteil liegt in der schonenden Behandlung des Fasergutes bei gleichzeitig sehr guten Reinigungsergebnissen. Diese guten Behandlungsergebnisse werden dadurch erreicht, daß das an den Siebtrommelmantelflächen unbeweglich gehaltene Fasergut von der Waschmittel enthaltenen Flüssigkeit durchströmt wird und anschließend ohne jegliche Beeinflusssung von mechanischen Wasch- oder Förderungseinrichtungen eine Schwimmstrecke durchläuft, in deren Bereich die beim Durchströmen gelösten Schmutzteile selbsttätig auf den Boden der Waschmaschinen herabfallen können.Raw wool washing machines of this type have proven themselves many times in practice. Your advantage lies in the gentle treatment of the fiber material with very good cleaning results. These good treatment results are achieved in that the liquid contained in the filter drum surfaces held immovable by the liquid contained in the detergent and then passes through without swimming any influence of mechanical washing or conveying devices, in the area of which the loosened dirt particles flow automatically to the bottom of the Washing machines can fall down.

Das im Grunde einzige Problem bei Maschinen dieser Art ist auch heute noch die problemlose, vollständige Beseitigung und Abtrennung der beim Waschen anfallenden ungeheuren Schmutzmengen. Der aus den Wollfasern sich lösende Schmutz, nämlich Erde, Sand und Tierfette, lagert sich auf dem durch das Badgehäuse sich erstreckenden perforierten Boden ab. Dies galt insbesondere bei der erheblich älteren Konstruktion nach der DE-OS 15 10 182, bei der der perforierte Boden sich horizontal durch das Behandlungsbad erstreckt. Die Schmutzstoffe fielen dort nicht vollständig durch den perforierten Boden in den Schmutzstoffabführraum, von wo auch während des Betriebes eine Reinigung erfolgt. Die Perforation des Bodens verstopfte vielmehr mit einzelnen Fasern oder gröberen Schmutzansammlungen, so daß es zu einer häufigen, den Arbeitsbetrieb unterbrechenden Reinigung der Maschine kam. Eine Besserung der Schmutzabsonderung erfolgte mittels einer Konstruktion nach der DE-OS 20 02 113, bei der oberhalb des perforierten Bodens eine Flüssigkeitsströmung erzeugt wird, die ununterbrochen oder in Intervallen die auf den Boden sich ablagernden Schmutzstoffe aufwirbeln sollte. Als Flüssigkeitsströmung dient die, die sowieso notwendig ist, um die aus den Siebtrommeln abgeführte Flüssigkeit im Kreislauf wieder der Außenseite der Siebtrommel in den Behandlungraum zurückzuführen. Deshalb wurde der dazu notwendige Verteilkanal unterhalb des perforierten Bodens angeordnet und die Ausströmöffnungen dieses Kanals dort angeordnet, wo sich im allgemeinen der Schmutz ablagerte. Auch diese Maßnahmen befriedigten nicht. Die Schmutzstoffe lagerten sich seitlich der Ausströmöffnungen ab.The only problem with machines of this type is still today the problem-free, complete removal and separation of the enormous amounts of dirt accumulating during washing. The dirt that loosens from the wool fibers, namely earth, sand and animal fats, is deposited on the perforated floor that extends through the bathroom housing. This was particularly true in the considerably older construction according to DE-OS 15 10 182, in which the perforated floor extends horizontally through the treatment bath. The pollutants did not completely fall through the perforated floor into the pollutant discharge area, from where cleaning takes place even during operation. Rather, the perforation of the floor clogged with individual fibers or coarse dirt accumulations, so that it became a frequent Work interrupting cleaning machine came. An improvement in the separation of dirt was achieved by means of a construction according to DE-OS 20 02 113, in which a liquid flow is generated above the perforated floor, which should whirl up the contaminants deposited on the floor continuously or at intervals. The liquid flow is that which is necessary anyway in order to return the liquid discharged from the sieve drums in the circuit back to the outside of the sieve drum into the treatment room. For this reason, the distribution channel required for this was arranged below the perforated floor and the outflow openings of this channel were arranged where the dirt generally deposited. These measures were also unsatisfactory. The contaminants settled to the side of the outflow openings.

Eine weitere Besserung dieses Problems ergab sich durch die Konstruktion nach der DE 23 57 055 A1, von der die Erfindung ausgeht. Dort wurden sämtliche bisher horizontal ausgerichtete Flächen des perforierten Zwischenbodens schräg gestellt, um den Schmutz selbsttätig in Richtung der Schmutzabführräume rutschen zu lassen. Da bei dieser Ausrichtung der perforierte Boden in etwa der Krümmung der Siebtrommeln angepaßt wurde, lagerte sich der Schmutz jetzt in den konvex nach innen, also unterhalb der Siebtrommeln, und nach außen gekrümmten Bereichen, also zwischen die beiden Siebtrommeln. Um dort. im Bereich der Schwimmstrecke eine Anhäufung der Schmutzstoffe zu verhindern, wurde der Flüssigkeitsrückführkanal in der Mitte zwischen die beiden Siebtrommeln angeordnet. In der Praxis hat es sich leider herausgestellt, daß die Schmutzstoffe sich dennoch auf den Zwischenboden ablagern. Dies gilt sowohl im Bereich der Ausströmöffnungen, im Bereich der Schwimmstrecke als auch im Bereich der Siebtrommeln.A further improvement of this problem resulted from the construction according to DE 23 57 055 A1, from which the invention is based. There, all previously horizontally aligned surfaces of the perforated false floor were inclined to allow the dirt to slide automatically in the direction of the dirt removal rooms. Since the perforated base was adapted to the curvature of the sieve drums in this orientation, the dirt now settled in the convex areas, ie below the sieve drums, and outwardly curved areas, ie between the two sieve drums. To there. To prevent the accumulation of contaminants in the area of the swimming section, the liquid return channel was arranged in the middle between the two sieve drums. In practice, unfortunately, it has been found that the pollutants nevertheless deposit on the intermediate floor. This applies both in the area of the outflow openings, in the area of the swimming zone and in the area of the sieve drums.

Der Erfindung liegt die Aufgabe zugrunde, nach wie vor eine Vorrichtung der anfangs genannten Art derart weiterzuentwickeln, daß sie selbstreinigend wirkt. Es soll eine kontinuierliche Waschbehandlung möglich sein, ohne daß überhaupt den Betrieb unterbrechende Reinigungsvorgänge notwendig sind.The invention has for its object to continue to develop a device of the type mentioned in such a way that it has a self-cleaning effect. A continuous washing treatment should be possible without the need for cleaning operations which interrupt the operation.

Eine Lösung des Problems ist überraschend durch die Erkenntnis gefunden, daß es notwendig ist, über die gesamte Länge des Bades eine Flüssigkeitsströmung , und zwar parallel zu dem durch das Bad transportierten Vlies zu erzeugen. Diese zusätzliche Strömung muß unterhalb des Vlieses und oberhalb des Zwischenboden vorhanden sein, damit durch sie die ausfallenden Schmutzstoffe aufgefangen und aufgewirbelt werden bis sie durch die Siebdecke in den Schmutzstoffabführraum ausfallen. Dies ist letztlich auch nur dann möglich, wenn die Wollfasern sich gänzlich von den Schmutzstoffen gelöst haben.A solution to the problem has been surprisingly found by the knowledge that it is necessary to use one along the entire length of the bath To produce liquid flow, parallel to the fleece transported through the bath. This additional flow must be present below the fleece and above the intermediate floor so that the precipitating contaminants are caught and whirled up until they fall out through the sieve cover into the contaminant discharge space. Ultimately, this is only possible if the wool fibers have completely separated from the contaminants.

Zur Verwirklichung dieser Erkenntnis sieht die Erfindung folgende konstruktive Maßnahmen an der vorbekannten Vorrichtung vor, nämlich daß die in dem Badgehäuse umgewälzte Flüssigkeit ausschließlich am Anfang des Badgehäuses über den Kanal dem Behandlungsraum zugeführt ist, und daß eine dem Preßwalzenpaar zugeordnete Ausströmnase des perforierten Bodens unterhalb des Flüssigkeitsniveaus, aber höher endet als der tiefer angeordnete Preßspalt des Preßwalzenpaares. Wesentlich bei der erfindungsgemäßen Idee ist, daß die durch Zuführen der Flüssigkeit am Einlauf des jeweiligen Bades erzeugte Flüssigkeitsströmung nicht durch den Reinigungsvorgang entlang des ganzen Bades gestört wird. Dies ist möglich, wenn die im Bad umgewälzte Flüssigkeit nur am Einlauf durch den Kanal zu- und am Badende wieder abgeführt wird. Die Flüssigkeitsparallelströmung zum Vlies ist aber nur möglich, wenn auch am Ende des Bades eine größere Menge Flüssigkeit abläuft. Deshalb wurde die Ausströmnase am Ende des Behandlungsraumes erheblich tiefer als das Flüssigkeitsniveau angeordnet. Mit der abfließenden Flüssigkeit fließt dann auch das in dem Bad gereinigte Wollvlies ab und wird dem Preßwalzenpaar durch diese Strömung ohne Stockung zugeführt. Dazu ist dann auch der Preßspalt des Preßwalzenpaares tiefer angeordnet als die Ausströmnase. Dies erfolgt im Gegensatz zum Stand der Technik nach den oben genannten Offenlegungsschriften, bei denen stets der Preßspalt in Höhe des Flüssigkeitsniveaus innerhalb des Bades angeordnet ist, um möglichst wenig Flüssigkeit in der Presse ausquetschen zu müssen und auch möglichst wenig Wollfasern vor dem Quetschwalzenpaar durch abfließende Flüssigkeit zu verlieren. Diesen Nachteil nimmt die Vorrichtung nach der Erfindung in Kauf. Sie vermeidet aber dennoch einen Faserverlust, weil diese aus dem Vliesverband ausfließenden Fasern mit der Quetschflüssigkeit durch eine Rohrleitung wieder zurück in das Bad, und zwar an dessen Anfang gepumpt werden.To achieve this knowledge, the invention provides the following constructive measures on the previously known device, namely that the liquid circulated in the bath housing is supplied to the treatment room exclusively at the beginning of the bath housing via the channel, and that an outflow lug of the perforated bottom assigned to the pair of press rollers is below the liquid level , but ends higher than the lower press nip of the pair of press rolls. It is essential in the idea according to the invention that the liquid flow generated by supplying the liquid at the inlet of the respective bath is not disturbed by the cleaning process along the entire bath. This is possible if the liquid circulated in the bath is only fed in at the inlet through the channel and discharged again at the end of the bath. The liquid parallel flow to the fleece is only possible if a larger amount of liquid runs off at the end of the bath. For this reason, the outflow nose at the end of the treatment room was arranged considerably lower than the liquid level. The wool fleece cleaned in the bath then also flows off with the flowing liquid and is fed to the pair of press rolls by this flow without stagnation. For this purpose, the press nip of the pair of press rolls is then arranged lower than the outflow nose. In contrast to the prior art, this is done according to the above-mentioned laid-open publications, in which the press nip is always arranged at the level of the liquid within the bath in order to have to squeeze out as little liquid as possible in the press and also as little wool fibers in front of the pair of squeeze rolls due to flowing liquid to lose. The device according to the invention accepts this disadvantage. However, it avoids fiber loss, because these fibers flowing out of the nonwoven dressing and the squeezing liquid are returned to the bath through a pipeline the beginning of which are pumped.

Durch den Vorteil nunmehr nur noch am Badeinlauf einen quer über die Arbeitsbreite sich erstreckenden Flüssigkeitsrückführkanal vorsehen zu müssen, ist der Abtransport der Schmutzstoffe im Schmutzstoffabführraum nicht mehr durch irgendwelche Vorrichtungsteile gestört. Im Badgehäuse ist damit nur noch ein Schmutzstoffabführraum notwendig, der sich über die gesamte Länge des Badgehäuses erstreckt.The advantage of having to provide a liquid return channel extending across the working width now only at the bath inlet means that the removal of the contaminants in the contaminant discharge chamber is no longer disturbed by any device parts. In the bathroom housing, only a contaminant removal space is therefore required, which extends over the entire length of the bathroom housing.

Ein besonderes Augenmerk ist noch auf die Ausschwemmnase gerichtet, die nicht nur für den fortlaufenden Abtransport des ankommenden Wollvlieses sorgen muß, sondern auch für die gleichmäßige Entfernung der mitlaufenden Flüssigkeit.Particular attention is also paid to the washout nose, which not only has to ensure the continuous removal of the incoming wool fleece, but also the even removal of the accompanying liquid.

Die Rohwollwaschvorrichtung besteht aus mehreren die Flüssigkeit bis zu einem Niveau 2 aufnehmenden Badgehäusen 1, in denen jeweils drei Siebtrommeln 3, 4 und 5 drehbar gelagert sind. Der Behandlungsraum 6 in diesem Badgehäuse 1 ist von dem Schmutzstoffabführraum 7 durch einen perforierten Boden 8 getrennt. Dieser Boden ist der Krümmung der Siebtrommeln 3 - 5 angepaßt und zur Bildung des Behandlungsraumes 8 mit Abstand zur Siebtrommel 3 - 5 angeordnet. Zwischen den jeweiligen Siebtrommeln 3 - 5 ist jeweils eine Schwimmstrecke 9 für die Rohwolle 10 angeordnet, in deren Bereich der perforierte Boden 8 konvex nach außen gekrümmt ist. Der Schmutzstoffabführraum 7 ist durch einen Trichter 11 gebildet, an dessen Wänden die aus dem Vlies ausgefallenen Schmutzstoffe kontinuierlich der Abführöffnung 12 zurutschen.The raw wool washing device consists of several bath housings 1 which hold the liquid up to a level 2, in each of which three sieve drums 3, 4 and 5 are rotatably mounted. The treatment room 6 in this bathroom housing 1 is separated from the contaminant removal room 7 by a perforated floor 8. This base is adapted to the curvature of the sieve drums 3-5 and is arranged at a distance from the sieve drum 3-5 to form the treatment room 8. Between the respective screening drums 3 - 5 there is a floating section 9 for the raw wool 10, in the area of which the perforated base 8 is convexly curved outwards. The contaminant discharge space 7 is formed by a funnel 11, on the walls of which the contaminants precipitated from the fleece continuously slide towards the discharge opening 12.

Die durch die Perforation der jeweiligen Siebtrommel in das Innere derselben gedrungene Flüssigkeit fließt gemäß Fig. 2 an den Stirnseiten der Siebtrommel durch Öffnungen 13 selbsttätig in stirnseitig außen angeflanschte Längskanäle 14, 15 aus. Die in den Kanal 14 ausgeflossene Flüssigkeit gelangt über eine Rohrleitung 16 in den Kanal 15, von wo die Gesamtflüssigkeit mit Hilfe der Pumpe 17 in den am Anfang des Badgehäuses 1 quer über die Arbeitsbreite sich erstreckenden Kanal 18 gepumpt wird und aus diesem über eine Einströmnase 19 in den Behandlungsraum 6 fließt. Von dort fließt diese erneut im Kreislauf zugeführte Flüssigkeit einerseits durch das neu zulaufende Vlies 10 und dann durch die erste Siebtrommel 3, aber genauso aufgrund der im Überfluß zulaufenden Flüssigkeit parallel des Vlieses 10 entsprechend des Pfeiles 20. Das gleiche gilt im Bereich der Schwimmstrecke 9. Anschließend fließt wieder eine gewisse Menge durch die Siebtommel 4, aber der Rest erneut entsprechend des Pfeiles 21 in Richtung zum Auslauf, sprich zum Preßwalzenpaar 24, 27. Aufgrund dieser Parallelströmung 20, 21 können sich die aus dem Vlies 10 gelösten und herabfallenden Schmutzstoffe nicht auf der Oberfläche des perforierten Bodens ablagern. Entweder sie fallen gleich durch die Perforation des Bodens 8 in den Schmutzstoffabführraum 11 oder sie werden durch die Parallelströmung 20, 21 wieder aufgewirbelt, die evtl. an den Schmutzstoffen noch haftenden Wollfasern dem Vlies nach oben wieder zugeführt und diese solange gewaschen bis nur die Schmutzstoffe ausfallen und dann sofort in den Abführraum 11 fallen. Jedenfalls ist aufgrund der Strömung 20, 21 eine Ablagerung der Schmutzstoffe auf dem Boden 8 nicht möglich, die Parallelströmung über die ganze Länge des Bades wirkt selbstreinigend.According to FIG. 2, the liquid which has penetrated into the interior of the sieve drum through the perforation of the respective sieve drum automatically flows out through openings 13 at the ends of the sieve drum into longitudinal channels 14, 15 flanged on the outside on the end face. The liquid which has flowed into the channel 14 passes through a pipe 16 into the channel 15, from where the total liquid is pumped with the aid of the pump 17 into the channel 18 which extends across the working width at the beginning of the bath housing 1 and from there via an inflow nose 19 flows into the treatment room 6. From there, this liquid, which is again supplied in the circuit, flows on the one hand through the newly arriving fleece 10 and then through the first screening drum 3, but also because of the excess liquid flowing parallel to the fleece 10 according to arrow 20. The same applies in the area of the swimming section 9. Then a certain amount flows through the sieve drum 4 again, but the rest again according to the arrow 21 in the direction of the outlet, that is to say the press roller pair 24, 27. Because of this parallel flow 20, 21, the contaminants loosened and falling from the fleece 10 cannot dissolve deposit on the surface of the perforated floor. Either they immediately fall through the perforation of the base 8 into the contaminant removal space 11 or they are whirled up again by the parallel flow 20, 21, the wool fibers which may still adhere to the contaminants are fed back upwards and washed until such time as only the contaminants fail and then immediately fall into the discharge space 11. In any case, due to the flow 20, 21, the contaminants cannot be deposited on the floor 8; the parallel flow over the entire length of the bath has a self-cleaning effect.

Die Konstruktion des Auslaufs eines jeden Bades ist aus der Fig. 4 im einzelnen ersichtlich. Dort ist die Ausströmnase 22 tiefer angeordnet, als das Flüssigkeitsniveau 2 oder die Drehachse der Siebtrommel 5. Dies hat zwar zur Folge, daß eine große Menge der Behandlungsflüssigkeit zum Preßwalzenspalt 23 zusammen mit dem abzuquetschenden Wollvlies 10 ausströmt, jedoch ist es für die Wolle ohne Nachteil. Im Gegenteil, so ist auch für einen fortlaufenden Abtransport der Wolle gesorgt. Die Ausschwemmnase 22 des perforierten Bodens 8 ist mit Abstand vom Preßspalt 23 angeordnet. Der Abstand zwischen der unteren Preßwalze 24 und der Ausschwemmnase 22 ist durch ein zusätzliches perforiertes Bodenblech 25 überbrückt. Das Bodenblech 25 ist nach oben konvex gekrümmt. Aufgrund dieser Figuration des Bodenbleches 25 ist für einen schnellen Abtransport des abzuquetschenden Vlieses 10 gesorgt. Das Auslaufende 26 des Bodenbleches 25 ist nicht dem Quetschspalt 23, sondern der unteren Preßwalze 24 zugeordnet, so daß ein Stau von Wollfasern nicht erfolgen kann.The construction of the outlet of each bath can be seen in detail in FIG. 4. There, the outflow nose 22 is arranged lower than the liquid level 2 or the axis of rotation of the screen drum 5. This does have the consequence that a large amount of the treatment liquid flows out to the press roll nip 23 together with the wool fleece 10 to be squeezed, but it is without disadvantage for the wool . On the contrary, the wool is continuously transported away. The flushing nose 22 of the perforated base 8 is arranged at a distance from the press nip 23. The distance between the lower press roll 24 and the washout nose 22 is bridged by an additional perforated base plate 25. The bottom plate 25 is convexly curved upwards. Because of this figuration of the bottom plate 25, the fleece 10 to be squeezed is quickly removed. The outlet end 26 of the bottom plate 25 is not assigned to the nip 23, but rather to the lower press roller 24, so that wool fibers cannot jam.

Zum erleichterten Ausbau des Preßwalzenpaares 24, 27 oder auch zur besseren Reinigung des Preßspaltes 23 ist das Bodenblech 25 im Badgehäuse 1 zur Ausschwemmnase 22 hin und zurück verschwenkbar angeordnet.To facilitate removal of the pair of press rollers 24, 27 or also for better cleaning of the press nip 23, the bottom plate 25 in the bath housing 1 is arranged so that it can be pivoted back and forth to the flushing nose 22.

Unterhalb der Ausschwemmnase 22, unterhalb des Bodenbleches 25 und auch unterhalb des Preßwalzenpaares 24, 27 ist eine Flüssigkeitsauffangwanne 28 angeordnet, von der sowohl die abgequetschte Flüssigkeit, als auch abgelaufene Wollfasern aufgefangen und in dem Trichter 29 gesammelt werden. Mit Hilfe einer Pumpe 30 und eines zusätzlichen Rohres 31 werden die Fasern wieder zurück in den Wollverband geführt. Das Rohr 31 mündet am Badanfang an der Stelle 32 oder 33 in das Badgehäuse 1. Ein Verlust von Fasern ist auf diese Weise vollständig vermieden.Below the washout nose 22, below the base plate 25 and also below the pair of press rollers 24, 27, a liquid collecting trough 28 is arranged, from which both the squeezed liquid and the wool fibers that have run off are collected and collected in the funnel 29. With the help of a pump 30 and an additional tube 31, the fibers are fed back into the wool bandage. The tube 31 opens into the bath housing 1 at the point 32 or 33 in the bath.
