Definitions

  • the invention relates to a method for preventing contamination on a wall inside of a transport device for fibers intended for the production of fiberboard according to the preamble of claim 1. Furthermore, the invention relates to a corresponding device according to the preamble of claim 9.
  • the fibers are preferably made of lignocellulose and / or cellulosic materials.
  • the fiberboards are in particular lightweight, medium-density or high-density fiberboard.
  • a dry gluing is for example in the WO 02/14038 A1 described.
  • dry gluing a problem is that freshly glued wood fibers tend to adhere to walls of a transport device due to cold tack of the glue immediately after gluing, which adjoins the dry gluing unit and serves to pneumatically transport the fibers to another processing unit.
  • the cold tack or cold sticking force of the glue which is also referred to as "tack" exists only for a few seconds after wetting the fibers with glue.
  • the cold stickiness is reduced very rapidly because the transport air in the pneumatic transport device ensures short-term surface drying of the glue.
  • Impurities on a wall inside of the transport device are in practice a serious problem. In particular, the impurities can lead to so-called Leimflecken in the finished fiberboard at a detachment from the wall.
  • DE 102 47 413 A1 such as DE 102 47 414 A1 It is known to provide in a chute of a gluing device a jacket air stream surrounding the freshly glued fibers.
  • the shell air which may be energy-consuming preheated fresh air in a heat exchanger, serves to prevent caking on the walls of the chute. Since the shell air contains no fiber material, air turbulence can easily cause the glued fibers or glue mist (see below) to come into contact with the walls of the chute.
  • each of the DE 102 47 412 A1 , of the DE 102 47 413 A1 and the DE 102 47 414 A1 It is known to re-feed a portion of the fibers deposited in a cyclone to the fiber sizing. However, this measure is used exclusively to achieve a more effective gluing.
  • the invention has for its object to provide an effective and inexpensive complex method for preventing impurities on a Wandungsinnenseite a transport device. Furthermore, the invention has for its object to provide an associated device.
  • the object concerning the method is solved by the features of claim 1.
  • the fibers are fed to a transport device after the gluing, which takes place in the dry state, which generally takes place in a housing-free environment.
  • the fibers are transported pneumatically.
  • dried material is recycled to the stream of fibers which still have cold-tack adhesive (also called freshly glued fibers hereinafter) in or into the transport device.
  • the dried material is glued material which has been obtained in the course of further processing of the glued fibers and no longer has a cold-sticky glue.
  • the dried material is added to the stream of freshly glued fibers as early as possible after gluing.
  • the dried material can in particular be recycled so that it mixes with the still cold tacky glue having fibers and thus passes directly into the flow of these fibers.
  • the dried material rubs on the inside wall of the transport device and thus ensures that the wall remains clean.
  • the dried material absorbs glue mist that is in the transport air.
  • This glue mist is fine glue droplets, which are produced by spraying the glue in the dry gluing unit and do not reach the fibers to be glued, but remain in the air flow and can lead to contamination and caking on the inner walls of the transport device.
  • These free-floating residual glue droplets account for about 1% of the glue sprayed in the dry sifting unit.
  • the dried material Since the dried material has been recovered in the course of further processing of the glued fibers and thus originates from these fibers, it still has a heat which is retained by the return of the material to the entire fiber processing process. Furthermore, the recirculated material is also kept warm by the warm transport air.
  • the dried material is preferably returned so that it is guided in the transport device between the stream freshly glued fibers and the at least one wall inner side of the transport device. This prevents freshly glued fibers from coming into direct contact with the inside wall of the transport device.
  • the dried material is returned to the stream of freshly glued fibers in such a way that the freshly glued fibers are partially or completely encased by the dried material.
  • it can be provided in a tubular transport line that the freshly glued fibers move in a central region of the tube and this central region completely of dried material is surrounded, so that a direct contact of freshly glued fibers is prevented with the Wandungsinnenseite of the tube.
  • a pipe which is rectangular in cross section it is possible to guide the dried material along the four inner walls of the pipe and thereby to enclose the stream of freshly glued fibers.
  • the dried material can in particular be guided along a part of the wall inner sides or all wall inner sides of the section such that the stream of freshly glued fibers is at least partially enclosed by the dried material.
  • the further processing unit may in particular be a classifier or a molding machine.
  • a nonwoven fabric is formed after the glued fibers are usually spotted.
  • the spun fibers pass from a dosing bunker in metered fashion onto a forming belt as a function of its speed. From the scattered fleece usually an upper layer is removed by a scalping roller. Further, the web also typically passes through a side trimming unit where fibers are removed from the edges of the web. Subsequently, the web is fed to a press for pressing the raw plate.
  • the proportion of fibers that is separated from the scalping roller or Sobeklamungsaku from scattered nonwoven, depending on the strength and width of the fiber board to be produced amount of material amount up to 40% of the fiber, which is discharged from the dosing hopper on the forming belt.
  • the fibers separated by the scalping roll or the side trimming unit are recycled as recycling material into the processing process.
  • the return can be done in different ways. Most often, the separated fibers are fed pneumatically directly into a metering device of a fiber separator or into the fiber transport between a fiber separator and a molding machine or directly into a metering hopper of a molding machine. All three variants essentially require a fan, an air-fiber separator and a rotary valve.
  • the fibrous material which has been removed from the formed fibrous web by the scalping roll or the side trimming unit may be used partially or wholly as the dried material which is recycled to the stream of freshly glued fibers.
  • neither a further air-fiber separator nor another rotary valve are needed.
  • plants for the production of fibreboards have a scalping roller and a side trimming unit.
  • a scalping roller and a side trimming unit it may also be contemplated to use as dried material fibers which have been discharged directly from the stream of glued fibers for recycle to the stream of freshly glued fibers.
  • this recycling may also take place in addition to the recirculation of fibrous material produced by the scalping roll or side trimming unit, e.g. if this material is not enough.
  • this branching of the fibers takes place at a point in the processing process, where the fibers are no longer cold-tacky.
  • the branching point can be located, for example, between a sifter and a dosing hopper upstream of the forming machine.
  • MDF and HDF raw boards are mostly sanded to the specified thickness on both sides of wide-belt sanding machines.
  • the cut is usually 0.2 to 0.4 mm per side. This results in considerable amounts of grinding dust.
  • This sanding dust is usually supplied to incinerators. From practice it is also known to supply a proportion of the grinding dust to the pipe dryer in the case of wet gluing. However, the possible return amount of the grinding dust is limited and is usually between 2 to 4% based on atro fibers.
  • abrasive dust may be separated instead of into the fiber dryer or, together with fibrous material as described above, into the stream of freshly glued fibers in the fiber dryer Transport device are returned.
  • abrasive dust preferably in combination with fiber material, is recycled to the stream of freshly glued fibers.
  • the sanding dust can also be dust from chipboard.
  • the above object is achieved with respect to the device by the features of claim 9. With the device, the process can be performed. Essentially, the same advantages as described above in connection with the method result. Preferred embodiments of the device are described in claims 10 to 19.
  • the speed of the transport air in the transport device and in particular in the suction tube can be variably adjustable.
  • the device can be designed, in particular, such that the at least partially sheath of the stream of freshly glued fibers in the transport device extends as far as an air-fiber separator.
  • the means for returning the dried material are preferably designed such that the material adjacent to the dry glue unit reaches the stream of freshly glued fibers in the conveyor. In particular, the material can be added directly to or adjacent to an inlet opening of the transport device the stream freshly glued fibers.

  • the suction duct 5 is connected to a suction pipe 11.
  • the suction pipe 11 merges into a pneumatic transport line 12 which supplies the stream 7 of freshly glued fibers 60 to a fiber-air separator 13.
