Abstract

The cleaning residues of cotton are usually separated into spinnable quality fibers and waste. Therefore, it is important to conceive a separating process and arrangement of which the capacity is adapted to the output of individual mills of common size, and which does not require any transport means for collecting material from several mills, and which has a good efficiency. The solution lies essentially in a sorting inlet of the incoming waste (2) and the formation of fractions (81-83) which differ as to the concentration of impurities and quality fibers. The fractions are recirculated through the separating device (4) until the desired recovery rate is reached.

Description

Die Erfindung bezieht sich auf ein Verfahren und Aggregat zur Trennung von Baumwollabgängen in Gutfasern und Schmutz.The invention relates to a method and unit for separating cotton waste in good fibers and dirt.

Bei der Gewinnung von Baumwolle sowie bei der Baumwollreinigung in der Spinnerei fallen Abgänge an. Die Abgänge enthalten einen hohen Prozentsatz spinnbarer Gutfasern, die für die Spinnerei zurückgewonnen werden sollen.Disposals are incurred when extracting cotton and cleaning cotton in the spinning mill. The exits contain a high percentage of spinnable good fibers that are to be recovered for the spinning mill.

Bein Stand der Technik werden die Abfälle gesammelt und als minderwertige Rohstoffe an an spinnereifremde Produktionen abgegeben. Es wurde versucht die Abgänge durch eine Anzahl geeigneter Maschinen wiederaufzubereiten.-Das gelingt. Der Durchsatz solcher Anlagen ist jedoch so hoch, daß sie nicht wirtschaftlich ausgelastet werden können. Ein Transport der Abgänge über große Strecken ist nicht wirtschaftlich, sodaß solche Anlagen keine weite Verbreitung gefunden haben.In the state of the art, the waste is collected and given to non-spinning productions as inferior raw materials. An attempt was made to reprocess the exits using a number of suitable machines. However, the throughput of such plants is so high that they cannot be used economically. Transporting the outlets over long distances is not economical, so that such systems have not been widely used.

Weiter ist eine Maschine bekannt, die einfach aufgebaut ist und eine Trennung der Abgänge in Gutfasern und Schmutz bewirkt. Die Maschine ist unter dem Namen Shirley - Gerät bekannt. Die Aufgabe des Shirley - Gerätes besteht in einer volständigen Trennung der Gutfasern vom Schmutz, wie sie für Prüfzwecke notwendig ist.A machine is also known which is of simple construction and causes the outlets to be separated into good fibers and dirt. The machine is known under the name Shirley device. The task of the Shirley device is to completely separate the good fibers from the dirt, as is necessary for test purposes.

Das Shirley - Gerät besteht aus einer Speisevorrichtung und einer Auflösewalze, die Vorreißergarnitur trägt. Durch die Fliehkraft und eine besondere Luftführung wird die trennende Wirkung erreicht. Das an den Ausscheidestellen anfallende Material wird zur vollständigen Trennung wiederholt der Speisevorrichtung vorgelegt, das geschieht solange, bis die vollständige Trennung erreicht ist.The Shirley device consists of a feed device and a disintegration roller which carries the licker set. The separating effect is achieved by centrifugal force and a special air flow. The material accumulating at the separation points is repeatedly submitted to the feed device for complete separation, this continues until the complete separation is achieved.

Der Stand der Technik ist unbefriedigend, weil es lediglich ein Verfahren gibt, daß sehr große Mengen Abgänge brauchbar aufarbeiten kann. Vielerorts ist es jedoch nicht sinnvoll einsetzbar, da nicht genügend Abfälle zur Verfügung stehen.The prior art is unsatisfactory because there is only one method that very large amounts of Ab can work up gears usably. In many places, however, it is not useful because there is not enough waste available.

Die im Shirley - Gerät durchsetzbaren Mengen sind so gering, daß an einen industriellen Einsatz nicht gedacht werden kann.The quantities that can be implemented in the Shirley device are so small that industrial use cannot be considered.

Die Erfindung hat sich die Aufgabe gestellt, Abgänge aus Baumwolverarbeitungsprozessen durch ein besonders dafür abgestimmtes Verfahren in Gutfasern und Schmutz zu trennen, was dadurch wirtschaftlich erreicht werden soll, daß in einer Trennvorrichtung Fraktionen gebildet werden, die ihrem Charakter gemäß einer unterschiedlichen Behandlung innerhalb eines Aufbereitungsaggregates unterworfen werden sollen.The invention has set itself the task of separating exits from cotton processing processes by a specially coordinated process in good fibers and dirt, which is to be achieved economically that fractions are formed in a separating device, which are subjected to their character according to a different treatment within a processing unit should be.

Zweck der Erfindung ist es, ein in seinem Durchsatz auf den Hauptprozeß abgestimmtes Aggregat zu erstellen, was in Nachbarschaft zum Hauptprozeß betrieben werden kann, wobei die anfallenden Gutfasern wieder in den HauptprozeB eingeführt werden.The purpose of the invention is to create an aggregate which is matched to the main process in terms of its throughput and which can be operated in the vicinity of the main process, the resulting good fibers being reintroduced into the main process.

Erfindungsgemäßkönnen die Abfälle durch ein spezielles Verfahren, das in einem Aggregat abläuft, wirtschaftlich in Gutfasern und Schmutz bzw. Abfall getrennt werden. Die Abgänge werden über eine Speisevorrichtung portionsweise einer Trennvorrichtung zugeführt und in verschiedene Fraktionen zerlegt. Die Fraktionen enthalten unterschiedliche Konzentrationen von Gutfasern und Schmutz im Vergleich zu den vorgelegten Abgängen. Jede Fraktion wird gesondert gesammelt und nach Durchlauf wenigstens einer Portion fraktionsweise der Trennvorrichtung erneut vorgelegt. Die Trennvorrichtung wird dabei umgesteuert,.dh. jede Fraktion erfährt eine ihrem .-Charakter gemäße Bearbeitung. Es wurde gefunden, daß an den Abscheidestellen der einzelnen Fraktionen immer typische Materialkonsistenzen auftreten. Diese werden gezielt weiterbearbeitet.According to the invention, the wastes can be economically separated into good fibers and dirt or waste by a special process which takes place in an aggregate. The outlets are fed in portions to a separating device via a feed device and broken down into different fractions. The fractions contain different concentrations of good fibers and dirt compared to the exits. Each fraction is collected separately and after passing through at least one portion in fractions it is again presented to the separating device. The separating device is reversed, that is. each faction undergoes processing in accordance with its character. It was found that typical material consistencies always occur at the separation points of the individual fractions. These are processed in a targeted manner.

Die besondere Weiterbehandlung kann erreicht werden, indem die Trennorgane mit geänderten Geschwindigkeiten betrieben werden. Es ist weiter möglich, bestimmte Abscheidestellen zeitweise zu schließen und damit zu überbrücken, sodaß das Material intern einen anderen Weg durch die Trennorgane nimmt. Es ist weiter möglich, das Material an anderen Trennorganen unter Umgehung vorgelagerter Trennorgane einzuspeisen.The special further treatment can be achieved by operating the separating elements at different speeds. It is also possible to temporarily close certain separation points and thereby bridge them, so that the Material takes a different path internally through the separation organs. It is also possible to feed the material to other separators bypassing upstream separators.

Das Material durchläuft intern die Trennvorrichtung solange, bis es in einem wirtschaftlichen Maße getrennt ist. Das muß nicht die maximal mögliche Trennung sein.The material passes through the separating device internally until it is economically separated. That doesn't have to be the maximum possible separation.

Die Gutfasern, die an bestimmten Stellen angereichert anfallen, können dem Hauptprozeß ständig zugeführt werden, es ist aber auch verfahrensgemäß, wenn diese die Trennvorrichtung wiederholt passieren. Der Abfall wird ausgeschieden.The good fibers, which accumulate at certain points, can be fed continuously to the main process, but it is also procedural if they pass the separating device repeatedly. The waste is excreted.

Eine Modifikation des Verfahrens ist gegeben, wenn die an die Speisung zurückgelieferten Fraktionen einer Siebung unterworfen werden. Dabei werden die losen Schmutzpartikel abgetrennt und belasten den Prozeß nicht mehr. Als besonders geeignet haben sich Luftstrahlsiebe und Zyklone erwiesen. Es hat sich weiter gezeigt, daß die an der ersten Abscheidestelle anfallende Fraktion, die noch grob ist, vorteilhaft kontinuierlich zurückgeführt wird. Dabei wird der lose Schmutz abgesiebt und der Rest der Fraktion an die Speisevorrichtung weitergeleitet.The process is modified when the fractions returned to the feed are subjected to screening. The loose dirt particles are separated and no longer burden the process. Air jet sieves and cyclones have proven to be particularly suitable. It has also been shown that the fraction obtained at the first separation point, which is still coarse, is advantageously continuously recycled. The loose dirt is sieved off and the rest of the fraction is passed on to the feed device.

Zur Durchführung des Verfahrens ist ein besonderes Aggregat notwendig. Es besteht aus einer Speisevorrichtung, einer Trennvorrichtung mit verschließbaren Abscheidestellen, den Abscheidestellen zugeordneten Speichern zur Aufnahme der Fraktionen und einer internen Transportvorrichtung zur Rückführung des Materiales an die Speisung, zur Abführung der Abfälle und zum Transport der Gutfasern in den HauptprozeB. Der interne Transport wird vorzugsweise pneumatisch abgewickelt.A special unit is required to carry out the method. It consists of a feeding device, a separating device with lockable separating points, the storage points assigned to the separating points for receiving the fractions and an internal transport device for returning the material to the feed, for removing the waste and for transporting the good fibers in the main process. The internal transport is preferably carried out pneumatically.

Bei einem pneumatischen Transport ist eine für alle Speicher wirksame Dosiervorrichtung angeordnet. Sie hat die Aufgabe, den amorphen Speicherinhalt in Flocken aufzulösen, die im Luftstrom transportfähig sind. Als Arbeitsorgan genügt eine Stiftwalze den Anforderungen. In unmittelbarer Nähe der Dosiervorrichtung kann durch eine besondere Öffnung Hilfsluft zugemischt werden, wodurch der Flockenfluß im Luftstrom stabilisiert wird.In the case of a pneumatic transport, a metering device which is effective for all stores is arranged. Its task is to dissolve the amorphous storage content in flakes that can be transported in the air flow. As a working organ, a pin roller meets the requirements. Auxiliary air can be mixed in through a special opening in the immediate vicinity of the metering device, thereby stabilizing the flow of flakes in the air flow.

Die Speiesevorrichtung weist Zuführmittel auf, die eine sequentielle Speisung der Trennvorrichtung mit den einzelnen Fraktionen erlauben, ohne daß es vorher zu einer Vermischung kommt. Derselbe Zweck kann erreicht werden, indem mehrere parallele Füllschächte angeordnet sind, die abwechselnfauf eine Speisewalze arbeiten.The feed device has feed means which allow sequential feeding of the separating device with the individual fractions without mixing beforehand. The same purpose can be achieved by arranging several parallel feed chutes, which work alternately on one feed roller.

Zum Zweck der Umgehung von Trennorganen können weitere Speisewalzen angeordnet sein.Additional feed rollers can be arranged for the purpose of bypassing separating elements.

Die Trennorgane der Trennvorrichtung bestehen aus Garniturwalzen bekannter Art. Es können mehrere Walzen angeordnet sein, die zueinander in Abnahme oder Kardierstellung stehen. Zweckmäßig nimmt die Spitzenzahl und die Umfangsgeschwindigkeit der Walzen zu, wobei die Durchmesser abnehmen.The separating members of the separating device consist of clothing rollers of known type. Several rollers can be arranged, which are mutually in the acceptance or carding position. The number of tips and the peripheral speed of the rollers expediently increase, the diameters decreasing.

Die Garniturwalzen besitzen Abscheidestellen bekannter Art. Sie sind verschließbar ausgebildet, wodurch sich in Verbindung mit einer internen Transportvorrichtung unterschiedliche Materialführungen durch das Aggregat ergeben bzw. verwirklichen lassen.The clothing rollers have separating points of a known type. They are designed so that they can be closed, so that in connection with an internal transport device different material guides through the unit can result or be realized.

Die Faserführungsflächen der Trennorgane können gleichfalls Garnierungen tragen. Insbesondere am ersten Trennorgan zwischen Speisewalze und erster Abscheidestelle kann eine Garnierung angeordnet werden, die nicht wie üblich in Kardierstellung zur Garnierung des Trennorganes steht. Zusammen mit Belüftungsöffnungen, die alternierend Blas- und Saugluft führen, wird das Material entstaubt. Die Garnierung wirkt -als intensieves Wirbelfeld, das den Staub löst. Die besondere Ausrichtung der Spitzen verhindert eine Füllung der Garnierung und die Fasern werden im Gegensatz zu den Staubpartikeln gehindert, dem Luftstrom zu folgen.The F aserführungsflächen the separating members can also carry toppings. In particular, a garnish can be arranged on the first separating element between the feed roller and the first separating point, which is not, as usual, in the carding position for garnishing the separating element. The material is dedusted together with ventilation openings that alternate between blowing and suction air. The garnish acts as an intense swirl field that loosens the dust. The special orientation of the tips prevents the garnish from filling and, unlike the dust particles, the fibers are prevented from following the air flow.

Bei einer Verfahrensmodifikation mit einer zusätzlichen Siebung in der Materialrückführung kommt neben einer Dosiervorrichtung eine Auflösevorrichtung zum Einsatz. Diese bewirkt eine intensive Durchmischung der Abgänge und der Transportluft. Insbesondere bei Verwendung eines Zyklones als Siebvorrichtung liegt die Auflösevorrichtung nahe dem Einlaufstutzen. Sie besteht aus garnierten, schnell rotierenden Walzen. Die Drehachsen der garnierten Walzen liegen vorteilhaft parallel zur Drehachse des Wirbels im Zyklon. Die Abnahme des Materiales wird durch strömungsgünstige Leibleche erleichtert, wobei zusätzlich Hilfsluft zugeführt wird.In the case of a process modification with an additional sieving in the material return, a dissolving device is used in addition to a metering device. This causes an intensive mixing of the outlets and the transport air. In particular when using a cyclone as a screening device, the opening device is close to the inlet connection. It consists of garnished, rapidly rotating rollers. The axes of rotation of the garnished rollers are advantageously parallel to the axis of rotation of the vortex in the cyclone. The removal of the material is facilitated by aerodynamic corpses, whereby auxiliary air is also supplied.

Das Aggregat besitzt eine Steuerung, die programmierbar ist. Das Programm enthält alle notwendigen Informationen um eine Portion bzw. ein Arbeitsspielmit allen Materialdurchläufen, Geschwindigkeiten der Trennorgane und verschiedener möglicher Wege zu realisieren. Die Programmierung erfolgt nach Erfahrungswerten. Wegen der großen Möglichkeiten in der Verfahrensführung kann das Aggregat ohne Umbauten durch bloßes Umsteuern auf verschiedene Abgansarten eingestellt werden.The unit has a control that is programmable. The program contains all the information necessary to implement a portion or a work cycle with all material runs, speeds of the separating elements and various possible ways. Programming is based on experience. Because of the great possibilities in the process management, the unit can be adjusted to different types of exhaust without simply having to change the direction.

Eine vollkommenere Ausbildung des Aggregates sieht den Einbau von Gebern vor, die auf relevante Parameter von Abgängen bzw. deren Fraktionen reagieren. Zusammen mit einem Prozeßführungssystem bekannter Art optimiert sich das Aggregat selbst.A more complete design of the unit provides for the installation of sensors that react to relevant parameters of outlets or their fractions. Together with a process control system of a known type, the unit optimizes itself.

Nachfolgend wird die Erfindung anhand eines Ausführungsbeispieles näher beschrieben.The invention is described in more detail below using an exemplary embodiment.

In einem Aggregat nach Fig. 1 wird der aus einem Hauptprozeß 1 stammende Abgang 2 einer Speisevorrichtung 3 zugeführt. Die Speisevorrichtung 3 speist die Trennvorrichtung 4. Die Trennvorrichtung 4 besteht hier aus drei Trennorganen 41, 42 und 43, die vier Abscheidestellen 51, 52, 53 und 54 aufweisen, wovon drei verschließbar ausgebildet sind. Dadurch kann der Materialfluß in der Trennvorrichtung 4 gesteuert werden. Den Abscheidestellen 51, 52 und 53 sind Speicher 61, 62 und 63 zugeordnet. Sie nehmen die anfallenden Fraktionen 8 auf und geben sie verfahrensgemäß an ein internes Transportsystem 7 ab. Zum internen Transportsystem 7 gehört eine Dosiervorrichtung 71, die aus einer amorphen Fraktion 8 Flocken erzeugt. Die Flocken können beispielsweise pneumatisch zur Speisevorrichtung 3 transportiert werden.In an assembly according to FIG. 1, the outlet 2 originating from a main process 1 is fed to a feed device 3. The feeding device 3 feeds the separating device 4. The separating device 4 here consists of three separating members 41, 42 and 43, which have four separating points 51, 52, 53 and 54, three of which are closable. The material flow in the separating device 4 can thereby be controlled. The separating points 51, 52 and 53 are assigned memories 61, 62 and 63. They take up the resulting fractions 8 and transfer them to an internal transport system 7 according to the method. The internal transport system 7 includes a metering device 71 which produces 8 flakes from an amorphous fraction. The flakes can be transported pneumatically to the feed device 3, for example.

Die Speisevorrichtung 3 besitzt in der gezeigten Ausführung parallele Füllschächte 31, 32 und 33 in die die einzelnen Fraktionen 8 ohne gegenseitige Durchmischung einer Speisewalze zugeführt werden.In the embodiment shown, the feed device 3 has parallel filling shafts 31, 32 and 33 into which the individual fractions 8 are fed to a feed roller without intermixing.

Verfahrensgemäß durchlaufen die an den Abscheidestellen 5 anfallenden Fraktionen 81, 82 und 83 die Trennvorrichtung 4 auf unterschiedlichen Wegen und mit unterschiedlichen, dh. auf die jeweilige Fraktion abgestimmten Arbeitsgeschwindig- keiten der Trennorgane 41, 42 und 43. Die Gutfasern 9 werden in den HauptarbeitsprozeB 1 zurückgeführt, während nach einer bestimmten Anzahl von Durchläufen der ausgebeutete Abfall 10 ausgeschieden wird. In dieser Art wird portionsweise weitergearbeitet.According to the method, the fractions 81, 82 and 83 occurring at the separating points 5 pass through the separating device 4 in different ways and with different, ie. rbeitsgeschwindig- on the respective fraction A matched speeds of the separating members 41, 42 and 43. The lint 9 are returned to the HauptarbeitsprozeB 1, while is eliminated after a certain number of passes of the waste exploited 10th This is continued in portions.

Eine erfindungsgemäße Modifikation ist in Fig. 2 dargestellt. Innerhalb des internen Transportsystems 7 wird eine Siebvorrichtung 100 eingefügt. Es hat sich gezeigt, daß in der ersten Fraktion 81 viele lose Schmutzteile enthalten sind, die sofort abgetrennt werden können. Damit wird die Trennvorrichtung 4 entlastet. Es kann eine Fraktion 8 kontinuierlich abgesiebt und rückgespeist werden. Es ist weiter möglich, daß alle Fraktionen 81, 82 und 83 nacheinander abgesiebt und zurückgespeist werden.A modification according to the invention is shown in FIG. 2. A screening device 100 is inserted within the internal transport system 7. It has been shown that the first fraction 81 contains many loose dirt particles which can be removed immediately. This relieves the separation device 4. A fraction 8 can be continuously screened and fed back. It is also possible that all fractions 81, 82 and 83 are screened and fed back one after the other.

Als Siebvorrichtung 100 wird hier ein bekannter Zyklon 101 eingesetzt, der vor seinem Einlaufstutzen eine zusätzliche Auflösevorrichtung 102 besitzt. Sie erzeugt eine intensive Mischung von Material und Luft, wobei die Flocken bis zu ihren einzelnen Bestandteilen aufgelöst werden. Die dafür erforderliche, hinreichend große Luftmenge wird durch Hilfsluftführungen 104 zugeführt, die sowohl an der Auflösevorrichtung 102 als auch an der Dosiervorrichtung 71 münden. Sie erleichtern gleichzeitig die Materialabgabe an diesen Arbeitsstellen. Dem Zyklon 101 folgt die Speisevorrichtung 3. Das Aggregat nach Fig. 1 wird um die Vorrichtungen aus Fig. 2 erweitert.A known cyclone 101 is used here as the screening device 100, which has an additional opening device 102 in front of its inlet connection. It creates an intensive mixture of material and air, whereby the flakes are broken down down to their individual components. The sufficiently large amount of air required for this is supplied by auxiliary air ducts 104, which open both at the opening device 102 and at the metering device 71. At the same time, they make it easier to deliver materials to these workplaces. The cyclone 101 is followed by the feed device 3. The unit according to FIG. 1 is expanded to include the devices from FIG. 2.

In Fig. 3 ist ein einfaches Ausführungsbeispiel eines Aggregates halbschematisch dargestellt. Als Trennorgane sind hier miteinander in Verbindung stehende Garniturwalzen 411, 422 und 433 eingesetzt. Sie besitzen verschließbare Abscheidestellen 511, 522 und 533. Die Garniturwalzen 411, 422 und 433 sind hierbei in Kardierstellung zueinander eingesetzt. Sie weisen eine steigende Spitzenzahl, sowie eine abgestuft steigende Fliehkraftwirkung auf. An der vierten Abscheidestelle 544 kann das Material beispielweise durch Saugluft und durch Blasluft, sowie durch eine hier dargestellte Abnehmerwalze abgenommen werden, die mir einer Abschlagwalze 555 zusammenarbeitet. Abnehmerwalze und Abschlagwalze 555 arbeiten geräuscharm und energiesparend. Analog zur prinzipiellen Ausführung eines Aggregates nach Fig. 1 sind Speicher 6 und ein internes Transportsystem 7 vorhanden. Eine dem Charakter einer Fraktion 8 angepasste Materialführung ist daher möglich.Strength in F. 3 shows a simple exemplary embodiment of a unit in a semi-schematic manner. Interconnecting clothing rollers 411, 422 and 433 are used here as separating elements. They have lockable Abscheidestellen 511, 522 and 533. The G arniturwalzen 411, 422 and 433 are used in carding position to each other. They have an increasing number of peaks and a gradual increase in centrifugal force. At the fourth separation point 544, the material can be removed, for example, by suction air and by blowing air, as well as by a take-off roller shown here, which works together with a knock-off roller 555. Pickup roller and chopper roller 555 are quiet and energy-saving. Analogous to the basic design of an assembly according to FIG. 1, storage 6 and an internal transport system 7 are present. A material guide adapted to the character of a fraction 8 is therefore possible.

In Fig. 4 ist eine besonders gestaltete Faserführungsfläche 600 dargestellt, wie sie insbesondere hinter einer Speisewalze 300 eingesetzt wird. Die Ausführung dient der Erzeugung eines intensiven Reibungs- und Wirbelfeldes. Die Spitzen 601 stehen nicht in Kardierstellung zu den Spitzen der Garniturwalze 602. Zwischen den Spitzen 601 münden Blasluftführungen 603 und Sciugluftführungen 604 in wechselnder Folge. Stark staubhaltige Filterabgänge beispielweise können so entstaubt werden. Die faserigen Bestandteile können dem Saugluftstrom 604 wegen der besonderen Ausrichtung der Spitzen 601 der Garnierung nicht folgen. Entsprechend sind die Saugluftführungerider durch die Fliehkraft vorgegebenen Bewegungsrichtung entgegengesetzt.4 shows a specially designed fiber guide surface 600, as is used in particular behind a feed roller 300. The design serves to generate an intensive friction and swirl field. The tips 601 are not in carding position with respect to the tips of the clothing roller 602. Between the tips 601, blowing air guides 603 and blowing air guides 604 open in alternating sequence. Filter outlets with a high dust content, for example, can be dedusted in this way. The fibrous components cannot follow the suction air flow 604 due to the special orientation of the tips 601 of the garnish. Accordingly, the suction air guiding guides are opposed by the direction of movement predetermined by the centrifugal force.
