Definitions

  • the invention relates to a method for operating a system for producing fiber, MDF, HDF, wood-based or plastic plates from fibers or fiber-like material according to the preamble of claim 1.
  • the invention further relates to a system according to the preamble of claim 8.
  • binder is understood to mean a so-called adhesive liquor which consists of an adhesive in its main component.
  • adhesive liquor which consists of an adhesive in its main component.
  • hardener emulsion, hardener, formaldehyde scavengers, dyes, insect repellent and antifungal agents and other additives are added. It is also common to use the adhesive without additives.
  • Suitable binders are not exhaustive: isocyanates (Mdl), melamine urea formaldehyde (MUF), urea formaldehyde (UF), MUPF or PF.
  • the chips are usually already delivered as chips or produced on site and fed to the gluing before or after drying.
  • Fibers are produced by Zerfaservorraum on site and conveyed after the defibration between two grinding discs through a transport tube (English: Blow Line) to a dryer.
  • the transport tube may have a length of up to 100m.
  • the Transport which is preferably carried out at supersonic speed in a relatively small tube of small inner diameter, the fibers are glued and then conveyed into a dryer.
  • This high-pressure gluing poses great challenges in a transport tube, since the flow is extremely turbulent, with a Reynolds number of 7 ⁇ 10 5 to 3 ⁇ 10 6 .
  • the speed of the fibers is in a range of at least 50 m / s up to a speed of 474 m / s.
  • the chips or fibers are usually dried, stored in bunkers and metered scattered on a base and pressed by pressing to sheets of material.
  • the necessary binder for gluing was previously introduced with nozzles in the transport tube, which dissolve the binder such that it is preferably injected with a size in the multi-digit micron range.
  • nozzles in the transport tube which dissolve the binder such that it is preferably injected with a size in the multi-digit micron range.
  • atomizing (pressure) spray nozzles it is possible to split the binder to an approximate size of 100 to 40 microns.
  • high-pressure nozzles which dissolve the binder on the nozzle head by relaxing in another pressure range.
  • Recent research and developments have shown new ways of injection possibilities, whereby either the binder at the outlet or already within the nozzle is dissolved by means of steam into very small particles. It is possible to increase the above-mentioned 40 micron droplet size of the binder by up to 20 microns below.
  • the smallest dissolution of the binder is urgently preferred.
  • the fiber material is transferred to a dryer, in the presently preferred embodiment a tube dryer, and dried.
  • a dryer in the presently preferred embodiment a tube dryer
  • the polluted air dryer are cleaned as exhaust gases depending on the need or environmental conditions in a pre-filter and then usually burned.
  • the dried fiber material is stored after the cyclone in bunkers and discharged as needed in a scattering station, which forms the fiber material to a spreading material on a continuously moving forming belt and transported in the direction of a press.
  • the spreading material mat is transferred to a continuously operating press and pressed by means of pressure and heat to form a material plate. After pressing, the surface grinding of the surfaces and the fabrication into specified sizes are carried out with subsequent stacking.
  • Fiber manufacturing facilities today are grateful for small orders to ensure that production is fully utilized in a 24/7 rhythm. Accordingly, it is no longer usual to drive the same type of product over several hours or even days, but the production thickness and / or the production density of the material plates to be produced are changed several times a day. This means that the throughputs of fibers in the transport tube are regularly adjusted to the required amount of glued material.
  • DE 195 06 353 A1 shows a method and apparatus for wetting with a fluid that tries to improve the Beleimitate over a targeted cross-sectional change of the transport tube in the region of the injection.
  • a reduced diameter of the transport tube is preferably used in front of the nozzles in order to increase the turbulence in the mixing zone.
  • the adaptation to different flow rates is made possible through the nozzle design, but has not proven optimal in practice.
  • the research and teaching in the following years to date has shown that the transport tubes are structurally designed in their design and are designed based on calculations to an average case. Usually other throughputs are not considered significantly or attempts are made through other means and ways to compensate for them.
  • DE 102 26 820 B3 describes a transport tube with several turns, which is applied by the deflection of the fiber flow on one side of the transport tube and is sprayed from the opposite side.
  • DE 100 59 881 A1 shows a plant for fiber processing, in which the Beleimzone has a double tube, wherein the inner perforated tube is externally supplied with compressed air to prevent sticking of the fibers to the inner tube wall.
  • DE 102 47 412 A1 also shows a cross-sectional change before gluing, wherein additionally by a splitting plate, the fibers are positioned in the direction of Beleimdüsen before they fall in a chute down.
  • the invention is therefore an object of the invention to provide a method for operating a system and a system with which optimal gluing the fibers at different throughputs per unit time can be achieved and at the same time the gluing of the fibers with binder meets high standards. In this case, further procedures and a system are to be created, through which an adjustment during production breaks during operation should be possible.
  • the solution for the method for operating a system is that to adapt to different throughput quantities of the fibers or for maintenance purposes, at least a part of the transport path is changed in its properties, the change being made such that by means of at least one switch between at least two transport tubes is switched over and / or at least a part of the transport tube is replaced with at least a second transport tube.
  • the solution for a system according to the invention is that to change the properties of the transport path at least part of the transport path consists of at least two transport tubes, wherein for the alternating control of these transport tubes at least one switch (4) and / or at least one flange in the transport path is arranged.
  • the invention under the properties of the transport tube, the embodiment of a transport tube, which must not always be designed to be constant in terms of its inner diameter. From the prior art examples, a variety of geometrical variations are known for the inner diameter of such a transport tube.
  • the teaching of the invention states that in the case of maintenance and / or in a production change, the transport tube can be adapted with its properties to the respective production. For this purpose, the possibilities described below are conceivable.
  • the system alone can be operated and has advantageous features, but of course is also particularly suitable for carrying out the method.
  • transport line stands for the transporting of fibers in a plant for the production of fiberboard, preferably by a defibrator (steam cooker) or a fiberizer of the transport is started and is preferably introduced into a tube dryer.
  • a defibrator steam cooker
  • a fiberizer of the transport is started and is preferably introduced into a tube dryer.
  • the fibers or the fiber-like material are glued in the transport path.
  • the invention solves a difficult problem for the plant operator. Because of the invention, plant operators are now able to easily accept small orders or marginal contracts, which work with their requirements on the edge of the admissibility of the production plant and thus challenge a higher consumption of raw materials. Due to the simple and inexpensive solution, which is also easy as Retrofit solution can be offered on the market, a conventional system at least a part or an entire transport pipe, in the embodiment of the fiberizer to the pipe dryer, extended. Thus, it is possible, adapted to the throughput of fibers per unit time, each to select the most suitable for this throughput transport pipe and integrate it into the production plant.
  • the changeover between the transport tubes can be carried out manually, by replacing the connections of two fixed long transport tubes (up to 100 m), or a part of the transport tube is replaced and coupled with suitable sealable flanges.
  • the switchover can be performed by means of switches, preferably also during production.
  • FIG. 1 begins the exemplary and simplified illustrated manufacturing process with a defibrator 1, also called shredder, which produces by thermomechanical defibration of wood, wood waste or similar starting material by means of pressure and steam fiber or fibers 20.
  • a defibrator 1 also called shredder
  • These fibers 20 are a transport line 22 a transport tube 2, (technical term in the industry or for the skilled person: "blow-line") passed, and during transport with one or more Beleimdüsen (in FIG. 1 not shown) glued.
  • the Fibers 20 introduced at a higher speed than the prevailing air velocity of the dryer air 6 in a tube dryer 3.
  • the necessary for the transport air velocity of the dryer air 6 in the tube dryer 3 is generated by a fan 12, which is supplied with heated (about 180 ° C to 220 ° C) and preferably dry air.
  • a fan 12 which is supplied with heated (about 180 ° C to 220 ° C) and preferably dry air.
  • the tube dryer 3 which can be up to 100 m long, the dried fibers are transferred to a cyclone 14, which separates the dryer air 6 from the fibers 20 and transfers the dryer air 6, possibly with a certain amount of dust, to a pre-filter 16.
  • the dryer air 6 is post-treated in a thermal exhaust air purification 17 and discharged to the environment.
  • the dried fibers are transferred in the cyclone 14 via a rotary feeder 15 to a fiber bunker 8 and controlled from there discharged into a spreader 10, which scatters a grit mat from the glued and dried fibers 20 on a forming belt 7. Subsequently, the spreading material mat is introduced into a continuously or discontinuously operating press 11 and, after being pressed into a fiber plate, transferred to the region of the post-processing 18. In post-processing, the fiberboard is assembled, sanded and stored accordingly.
  • the subsequent part of the process is its usual course and the fibers 20 are transferred after gluing over the remainder of the first transport tube 2 in the tube dryer 3 and transferred with at least one outlet nozzle 19 to the dryer air 6 in the tube dryer 3.
  • this process is modified insofar as that after the first switch 4 no further switch is present and the two transport tubes 2 and 9 have two separate outlet nozzle 19 in the tube dryer for transferring the fibers 20 to the dryer air 6.
  • two sets of nozzles 5 are necessary for this embodiment, since the nozzles 5 are configured separately for the corresponding transport tube 2 or 9.
  • a starting pipe 13 can be seen. This tube is used to sort out poor or insufficient fibers during startup and one To prevent their entry into the production process.
  • the present development does not understand such a start-up transport tube as a transport tube according to the invention, since it does not open into a tube dryer 3 or serves to weed out fiber material from the process.
  • FIG. 4 shows a simple solution to the problem of the invention, particularly helpful for retrofitting or tight space.
  • the second transport tube 9 is inserted into the transport tube 2 and has other properties, for example a different inner diameter, at least in parts than the substituted part of the transport tube 2.
  • a flanged solution with flanges 21 is basically no problem due to the small outer diameter of the transport tubes .
  • the coupling and sealing of the flanges 21 of the transport tubes 2, 9 can also be carried out automatically, if there is a need or desire for it.
  • On a graphic solution of such standard components has been omitted. The person skilled in the art will take the necessary measures to reliably produce such compounds according to the state of the art and according to the technical rules.
  • FIG. 5 In another alternative solution after FIG. 5 has the system or the defibrator 1 directly to three outputs, which can be switched between these outputs as needed. Again, a starting pipe 13 is introduced.
  • the system described or the method is extremely well suited for gluing nozzles which disperse the binder with steam before entering the transport tube and / or that the binder is comminuted with steam as it exits the nozzle Insert transport tube.
  • steam is used to split the binder in the range of less than 40 microns and thus to allow optimum injection of the fibers when injected into the transport tube.
  • These nozzles are particularly suitable because in the dispersion of the vapor with the binder in a mixing chamber in front of the nozzle itself or before entering the blowline, the dispersion can be optimally pressure-controlled, but in the transport tube a certain minimum speed of the fibers or the Steam needed.
