Abstract

The separator (5) connected to a transport conduit (2) of a filiform or band-shaped material is situated in the vacuum area of a blower (7) connected by a conduit (6) behind the separator in the current direction. In the transport conduit (2) there is arranged a comminuting device (4) to reduce the material in small lumps. Under the separator (5) there is arranged a mechanical extraction device (8) which sealingly closes the inner part of the separator to the atmosphere. The extraction device is comprised preferably of an alveole wheel sluice or of another appropriate assembly. The machine operates with a reduced number of costly members (4, 5, 8), reliably and without any danger of stuffing since said members are located in the underpressure area of the blower (7).

Description

Einrichtung zum Absaugen und Zerkleinern von in einem gasförmigen Medium förderbarem Material Device for suctioning and crushing material that can be conveyed in a gaseous medium
Die Erfindung betrifft eine Einrichtung zum Absaugen und Zerkleinern von in einem gasförmigen Medium förderbarem Material, insbesondere streifen- oder fadenförmigem "Endlos"- Material, das durch eine Absaugleitung mittels eines durch ein Gebläse erzeugten Förderstroms einem Abscheider zugeführt und zerkleinert wird.The invention relates to a device for suctioning and crushing material that can be conveyed in a gaseous medium, in particular strip or thread-like “endless” material, which is fed to a separator and shredded through a suction line by means of a conveying flow generated by a blower.
Einrichtungen dieser Art sind als pneumatische Absaugsysteme in der Industrie bekannt und dienen dazu, beispielsweise in der Papier-, Karton- oder Kunststoffolien-Industrie kontinuierlich anfallende "endlose" Randstreifen, die auch als Besäumstreifen bezeichnet werden, von einer Maschine, in der sie beim Besäumen einer Materialbahn entstehen, wegzutransportieren, um sie in einer entfernt liegenden Sammelstelle für den Abtransport oder für eine weitere Verarbeitung abzuscheiden oder zu sammeln.Devices of this type are known in the industry as pneumatic suction systems and are used, for example, in the paper, cardboard or plastic film industry to produce "endless" edge strips, which are also referred to as trimming strips, from a machine in which they are trimmed of a material web, to be transported away in order to separate or collect it in a remote collection point for removal or for further processing.
Bei den bekannten Absaugsystemen erfolgt die Trennung des zu fördernden Materials von dem für den Transport verwendeten Luftstrom in einem Abscheider, der in Strömungsrichtung hinter einem in der Absaugleitung angeordneten Gebläse in dessen Ueberdruckbereich angeordnet ist. Die Förderung des Materials zum Abscheider erfolgt demnach mit Ueberdruck. Bei den unterschiedlichen bekannten Absaugsystemen befindet sich entweder in der Absaugleitung vor dem Geblase und zwar dem Abscheider eine Zerkleinerungsvorrichtung zum Zerkleinern der Randstreifen, sodass das zerkleinerte Material das entsprechend ausgebildete Gebläse passieren muss, oder es ist in die Absaugleitung ein aus einer Kombination von Gebläse und Zerkleinerungsvorrichtung bestehendes Gerät, das auch als Schneidventilator bezeichnet wird, eingebaut, wobei ein speziell ausgebildetes Gebläse-Flügelrad mit besonderen Schneidkanten ausgerüstet ist. Diese Systeme weisen verschiedene Nachteile auf, insbesondere kann das Gebläse nicht auf seinen günstigsten Wirkungsgrad ausgelegt werden, weil das zu fördernde Material entweder das Gebläse in zerkleinerter Form passiert oder das Gebläse selbst das Zerkleinerungsgerät darstellt, sodass das Gebläse wegen seiner doppelten Funktion nicht ausschliesslich für die Luftförderung konstruktiv optimal ausgelegt werden kann. Weitere Nachteile bestehen darin, dass beim Stumpfwerden der Schneidkanten das zu fördernde Material sich um das Flügelrad des Gebläses wickeln kann, sodass die Anlage dann verstopfen kann.In the known suction systems, the material to be conveyed is separated from the air flow used for the transport in a separator which is arranged in the flow direction behind a blower arranged in the suction line in its overpressure area. The material is conveyed to the separator with overpressure. In the various known suction systems, either a shredding device for shredding the edge strips is located in the suction line in front of the blower, specifically the separator, so that the shredded material has to pass the appropriately trained blower, or it is in the suction line from a combination of blower and shredding device existing device, which is also referred to as a cutting fan, installed a specially designed fan impeller is equipped with special cutting edges. These systems have various disadvantages, in particular the blower cannot be designed for its best efficiency, because the material to be conveyed either passes through the blower in comminuted form or the blower itself is the comminution device, so that the blower is not exclusively used for the, because of its dual function Air delivery can be optimally designed. Further disadvantages are that when the cutting edges become blunt, the material to be conveyed can wrap around the fan impeller, which can then clog the system.
Ferner ist zum Absaugen von Randstreifen auch noch das Injektorsystem bekannt, bei dem das Material mittels eines Injektors angesaugt und einem auf der Ueberdruckseite angeordneten Abscheider zugeführt wird. Alle vorgenannten bekannten Systeme weisen wegen des relativ schlechten Wirkungsgrades einen hohen Energiebedarf auf und besitzen als weiteren Nachteil die Lärmerzeugung.Furthermore, the injector system is also known for vacuuming edge strips, in which the material is drawn in by means of an injector and fed to a separator arranged on the overpressure side. Because of the relatively poor efficiency, all of the known systems mentioned above have a high energy requirement and have a further disadvantage of generating noise.
Es ist ferner auch ein Absaugsystem zum Absaugen von aus Papier bestehenden Randstreifen bekannt, bei dem das Gebläse in Strömungsrichtung hinter dem Abscheider angeordnet ist, in welchem die unzerkleinerten Streifen mit einem Lösungsmittel oder Wasser besprüht werden, um sie über eine unterhalb des Abscheiders anschliessende Rohrleitung, die unter dem Flüssigkeitsspiegel in einen Behälter mündet, einer sofortigen Weiterverarbeitung zuzuführen, wobei der Abscheider unten einen Flüssigkeitsabschluss bzw. eine Flüssigkeitsabdichtung besitzt. Der Nachteil ist hierbei, dass das unzerkleinerte Material nass abgetrennt werden muss und dass der Abscheider und die anschliessenden Elemente des Systems aus gegen Rost geschütztem Material hergestellt sein müssen. Das nasse "Ehdlosmaterial" lässt sich nicht ohne weiteres aus dem Abscheider austragen, sondern muss unter Einsatz einer Pumpe zwischen dem Behälter und dem Abscheider aus diesem weggeführt werden.Also known is a suction system for suctioning edge strips made of paper, in which the fan is arranged behind the separator in the direction of flow, in which the uncrushed strips are sprayed with a solvent or water, in order to pass them over a pipeline connected below the separator, which opens into a container under the liquid level, for immediate further processing, the separator having a liquid seal or a liquid seal at the bottom. The disadvantage here is that the uncrushed material has to be separated wet and that the separator and the adjoining elements of the system have to be made of material that is protected against rust. The wet "crap material" cannot be easily extracted from the Discharge the separator, but must be led out of the container and the separator using a pump.
Der Erfindung liegt die Aufgabe zugrunde, streifenförmiges oder bandförmiges, verschiedenartiges Material mit einer bezüglich der notwendigen Apparate weniger urafanreichen Einrichtung in trockener Form zu fördern und abzuscheiden und dabei das den Förderstrom erzeugende Gebläse auf optimalen Wirkungsgrad auszulegen.The object of the invention is to convey and separate strip-like or band-shaped, different types of material in a dry form with a device that is less urafan-rich in terms of the necessary apparatus, and to design the blower generating the flow rate for optimum efficiency.
Zur Lösung dieser Aufgabe dient eine Einrichtung mit den Merkmalen des Anspruchs 1. In zweckmässiger Ausgestaltung ist eine Zerkleinerungsvorrichtung in der Förderleitung vor dem Abscheider und eine Zellenradschleuse hinter dem Abscheider angeordnet. Die Zerkleinerungsvorrichtung kann aber auch zwischen dem Abscheider und der mechanischen Ab Austragvorrichtung angeordnet sein, wobei die Zerkleinerungsvorrichtung zweckmässig eine Mühle und die mechanische Austragvorrichtung eine Zellenradschleuse ist. Ferner kann die Austragvorrichtung selbst als Zerkleinerungsvorrichtung ausgebildet sein. In diesem Fall ist die Austragvorrichtung eine mit gegeneinander arbeitenden Schneidkanten versehene Zellenradschleuse. In weiterer Abwandlung kann die Austragvorrichtung eine unterhalb des Abscheiders angeordnete, druckdicht gekapselte Ballenpresse mit einem Presskolben zum Zerkleinern des Materialstroms und chargenweisen Verdichten von Teilmengen des Materialstroms sein.A device with the features of claim 1 is used to achieve this object. In an expedient embodiment, a comminution device is arranged in the delivery line in front of the separator and a cellular wheel sluice behind the separator. The comminution device can also be arranged between the separator and the mechanical discharge device, the comminution device expediently being a mill and the mechanical discharge device being a cellular wheel sluice. Furthermore, the discharge device itself can be designed as a comminution device. In this case the discharge device is a cellular wheel sluice provided with cutting edges working against each other. In a further modification, the discharge device can be a pressure-tightly encapsulated baler arranged below the separator with a press piston for comminuting the material flow and batch-wise compression of partial quantities of the material flow.
Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung und den Zeichnungen, in denen verschiedene Ausführungsformen der Erfindung beispielsweise dargestellt sind. Es zeigen:Further details and advantages of the invention will become apparent from the following description and the drawings, in which various embodiments of the invention are shown, for example. Show it:

Bei der Einrichtung gemäss Fig. 1 ist das Ansaugende 1 einer Absaug- oder Förderleitung 2 nahe der Stelle an einer Maschine 3 angeordnet, an welcher die "endlosen" Randstreifen anfallen. Die Förderleitung 2 führt zu einer Zerkleinerungsvorrichtung 4 beispielsweise in Gestalt eines Zerhackers, der die "endlosen" Streifen zerkleinert. Von der Zerkleinerungsvorrichtung führt die Förderleitung 2 zu einem Abscheider 5 oder Abscheider-Filter, in den die Leitung einmündet. In gestrichelten Linien sind unter der Förderleitung weitere Förderleitungen und Zerkleinerungsvorrichtungen dargestellt, die parallel ebenfalls an den Abscheider 5 angeschlossen sein können und zu weiteren Maschinen führen, bei denen Randstreifen anfallen. Ebenso können auch mehrere Maschinen an einen Zerhacker angeschlossen sein.In the device according to FIG. 1, the suction end 1 of a suction or delivery line 2 is arranged close to the point on a machine 3 at which the "endless" edge strips are produced. The conveyor line 2 leads to a comminution device 4, for example in the form of a chopper, which comminutes the “endless” strips. The conveyor line 2 leads from the comminution device to a separator 5 or separator filter, into which the line opens. In dashed lines below the conveyor line, other conveyor lines and shredding devices are shown, which can also be connected in parallel to the separator 5 and lead to other machines where edge strips are produced. Likewise, several machines can also be connected to one chopper.
An .der Oberseite des Abscheiders 5 ist über eine Leitung 6 ein Gebläse 7 angeschlossen, das den für die Förderung notwendigen Unterdruck erzeugt. Hinter dem Abscheider kann je nach Bedarf noch ein Filter angeordnet sein. Der Abscheider 5 und die Förderleitung 2 einschliesslich der Zerkleinerungsvorrichtung 4 befinden sich somit im Unterdruckbereich.At the top of the separator 5, a blower 7 is connected via a line 6, which generates the vacuum necessary for the conveyance. A filter can be arranged behind the separator as required. The separator 5 and the delivery line 2, including the comminution device 4, are thus in the vacuum region.
Innerhalb des Abscheiders 5 gelangen die zerkleinerten Streifen nach unten zu einer Zellenradschleuse 8, die den Innenraum des Abscheiders 5 druckdicht gegen die At mosphäre abschliesst und durch die die zerkleinerten Streifen ausgetragen werden. Es kann auch eine andere druckdichte Austragvorrichtung vorgesehen werden, die beispielsweise aus senkrecht untereinander angeordneten Klappen in einem entsprechend ausgebildeten Kanal besteht, welche Klappen eine Schleusenkammer begrenzen und nacheinander öffnen. Ferner sind auch schneckenförmige Austragorgane einsetzbar.Within the separator 5, the shredded strips go down to a cellular wheel sluice 8, which pressurizes the interior of the separator 5 against the At closes the atmosphere and through which the shredded strips are discharged. Another pressure-tight discharge device can also be provided, which consists, for example, of flaps arranged vertically one below the other in a correspondingly designed channel, which flaps delimit a lock chamber and open them one after the other. Helical discharge elements can also be used.
Bei der Einrichtung gemäss Fig. 2 ist unterhalb des Abscheiders 5 zwischen diesem und der Austragvorrichtung 8 die vorzugsweise eine Zellenradschleuse ist, die Zerkleinerungsvorrichtung 9 angeordnet, die beispielsweise eine Mühle ist. Der Vorteil der an dieser Stelle unterhalb des Abscheiders angeordneten Mühle besteht darin, dass man bei einer Mehrzahl von an den Abscheider 5 angeschlossenen Förderleitungen 2, die das Streifenmaterial von verschiedenen Maschinen zum Abscheider transportieren, statt der in jeder Förderleitung notwendigen Zerkleinerungsvorrichtung beispielsweise in Form eines Zerhackers gemäss Fig. 1 bei der Einrichtung gemäss Fig. 2 nur eine Zerkleinerungsvorrichtung hinter dem Abscheider benötigt, die ein entsprechend grösseres Volumen an Streifenmaterial zu bewältigen hat und nicht innerhalb des Saugstroms arbeitet, weshalb diese Zerkleinerungsvorrichtung mit den für den individuellen Anwendungsfall geeigneten Zerkleinerungswerkzeugen arbeitet. Im Vergleich mit der Einrichtung gemäss Fig. 1 und bei Vorhandensein einer Mehrzahl von Förderleitungen 2 lassen sich demnach mit einer Einrichtung gemäss Fig..2 Investitionskosten und Energiekosten für den Antrieb der Zerkleinerungsvorrichtung einsparen. Im übrigen ist die Einrichtung gemäss Flg. 2 gleich ausgebildet wie die Einrichtung gemäss Fig. 1.In the device according to FIG. 2, the comminution device 9, which is for example a mill, is arranged below the separator 5 between the separator 5 and the discharge device 8, which is preferably a cellular wheel sluice. The advantage of the mill located below the separator is that with a plurality of conveyor lines 2 connected to the separator 5, which transport the strip material from different machines to the separator, instead of the shredding device necessary in each conveyor line, for example in the form of a chopper 1 requires only one shredding device behind the separator, which has to handle a correspondingly larger volume of strip material and does not work within the suction flow, which is why this shredding device works with the shredding tools suitable for the individual application. In comparison with the device according to FIG. 1 and when there are a plurality of delivery lines 2, investment device and energy costs for driving the comminution device can be saved with a device according to FIG. Otherwise, the facility according to Flg. 2 of the same design as the device according to FIG. 1.
Bei der Einrichtung gemäss Fig. 3 besteht der Unterschied darin, dass die Austragvorrichtung 10 noch zusätzlich die Funktion der Zerkleinerung übernimmt. Wenn diese Austrag Vorrichtung eine Zellenradschleuse ist, können an den Enden der die Zellen begrenzenden Flügel des Flügelrades Messer angeordnet sein, die mit stationären Schneidkanten zusammenarbeiten, sodass der aus Streifen bestehende Materialstrom zertrennt und gleichzeitig ausgetragen wird. Die Austragvorrichtung 10 übernimmt demnach drei Funktionen, nämlich den unter Unterdruck stehenden Abscheider 5 nach aussen druckdicht abzuschliessen, den Materialstrom zu zerkleinern und schliesslich diesen auszutragen.The difference in the device according to FIG. 3 is that the discharge device 10 additionally takes on the function of comminution. If this discharge Device is a cellular wheel sluice, knives can be arranged at the ends of the vanes of the impeller delimiting the cells, which work together with stationary cutting edges, so that the material stream consisting of strips is separated and discharged at the same time. The discharge device 10 accordingly performs three functions, namely to shut off the separator 5, which is under vacuum, pressure-tight to the outside, to shred the material flow and finally to discharge it.
Gemäss Fig. 4 kann als Austragvorrichtung auch eine Presse 11 unterhalb des Abscheiders angeordnet sein, die einen ständig hin und her bewegten Kolben 12 aufweist, der den Materialstrom durch Abscheren zerkleinert und chargenweise verdichtet, sodass in einem Presschacht 13 der Presse Ballen aus gepresstem Material gebildet werden, durch welche der Pressen-Innenraum ausreichend gegen aussen abgedichtet ist. Das übrige Gehäuse dieser Ballenpresse, welches die Antriebsmittel für den Kolben 12 umschliesst, ist ebenfalls druckdicht an den Abscheider 5 angeflanscht, womit die derart druckdicht gekapselte Ballenpresse 11 den Innenraum des Abscheiders 5 gegen die Atmosphäre druckdicht abschliesst.According to FIG. 4, a press 11 can also be arranged as a discharge device below the separator, which has a piston 12 that is constantly moved back and forth, which crushes the material flow and compresses it in batches, so that bales of pressed material are formed in a press shaft 13 of the press through which the interior of the press is sufficiently sealed from the outside. The remaining housing of this baler, which encloses the drive means for the piston 12, is also flanged to the separator 5 in a pressure-tight manner, so that the baler 11, which is encapsulated in such a pressure-tight manner, seals the interior of the separator 5 from the atmosphere in a pressure-tight manner.
Gemäss Fig. 5 ist als Austragvorrichtung eine druckdicht gekapselte Schneckenpresse 14 unterhalb des Abscheiders angeordnet. Die Schneckenpresse 14 hat die gleiche Funktion und arbeitet in entsprechender Weise wie die Ballenpresse 11 gemäss Fig. 4.5, a pressure-tightly encapsulated screw press 14 is arranged below the separator as the discharge device. The screw press 14 has the same function and works in a manner corresponding to the baler 11 according to FIG. 4.
Der Vorteil der erfindungsgemässen Einrichtung besteht darin, dass mit dem auf den optimalen Wirkungsgrad ausgelegten Gebläse Energie eingespart wird und dass das nur wenige Aggregate umfassende Absaugsystem sehr zuverlässig arbeitet, weil alle Aggregate im Unterdruckbereich liegen und Leitungen nicht verstopfen. Ferner ist der Investitionsaufwand geringer als bei vergleichbaren bekannten Einrichtungen. The advantage of the device according to the invention is that energy is saved with the blower designed for optimum efficiency and that the suction system, which comprises only a few units, works very reliably because all units are in the negative pressure range and lines do not become blocked. Furthermore, the investment is less than in comparable known facilities.
