Definitions

  • 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 stream generated by a blower.
  • 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.
  • the material to be conveyed is separated from the air flow used for the transport in a separator which is arranged in the direction of flow behind a fan arranged in the suction line in its overpressure area.
  • the material is conveyed to the separator with overpressure.
  • a shredding device in front of the blower and the separator for shredding the edge strips, so that the shredded material has to pass the correspondingly designed blower, or there is a combination of blower and shredding device in the suction line Device, which is also referred to as a cutting fan, installed, whereby a specially designed fan impeller is equipped with special cutting edges.
  • 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 for the 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.
  • 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 their relatively poor efficiency, all of the known systems mentioned above have a high energy requirement and have a further disadvantage of generating noise.
  • the invention is based on the object of conveying and separating strip-like or band-shaped, different types of material in a dry form with a device which is less extensive with respect to the necessary apparatus, and in doing so to design the blower generating the flow rate for optimum efficiency.
  • 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.
  • 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.
  • 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.
  • the suction end 1 of a suction or delivery line 2 is arranged close to the location 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.
  • 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 in which edge strips occur. Likewise, several machines can also be connected to one chopper.
  • a blower 7 is connected via a line 6, which generates the negative pressure necessary for the promotion.
  • 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.
  • the shredded strips reach a cellular wheel sluice 8, which seals the interior of the separator 5 from the atmosphere in a pressure-tight manner and through which the shredded strips are discharged.
  • Another pressure-tight discharge device can also be provided, which, for example, consists 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.
  • the crushing 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.
  • investment device and energy costs for driving the comminution device can be saved with a device according to FIG. 2. Otherwise, the device according to FIG. 2 has the same design as the device according to FIG. 1.
  • the discharge device 10 also 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, said blades working together with stationary cutting edges, so that the stream of material consisting of strips is separated and simultaneously discharged.
  • 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.
  • 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 by shearing 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 adequately sealed from the outside.
  • the rest of the 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 encapsulated in such a pressure-tight manner closes the interior of the separator 5 from the atmosphere in a pressure-tight manner.
  • 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.
  • 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.

Abstract

Le séparateur (5) relié à un conduit de transport (2) d'un matériau filiforme ou en forme de bande est situé dans la zone en dépression d'une soufflante (7) reliée par une conduite (6) derrière le séparateur dans le sens du courant. Dans le conduit de transport (2) est interposé un dispositif de hachage (4) pour réduire le matériau en petits morceaux. En dessous du séparateur (5) est disposé un dispositif mécanique d'extraction (8) fermant de manière étanche à l'atmosphère l'intérieur du séparateur. Le dispositif d'extraction est constitué de préférence d'une écluse à roue à alvéoles ou d'un autre ensemble approprié. L'installation fonctionne avec peu d'organes coûteux (4, 5, 8), de manière fiable et sans danger de bourrage vu que ces organes se trouvent dans la zone en dépression de la soufflante (7).
