Definitions

  • the invention relates to a method for gluing particles, wherein the particles are transported in a transport tube in a flow direction by means of a carrier medium, wherein at least one primary nozzle, a binder is injected into the transport tube and wherein by means of at least one secondary nozzle for the injection of compressed air and / or water and / or steam the injected binder predetermined a flow direction and / or it is atomized.
  • the invention further relates to a device for gluing particles with a transport tube, in which the particles are transported in a flow direction by means of a carrier medium, at least one primary nozzle which injects a binder into the transport tube and at least one second nozzle for the injection of compressed air and / or Water and / or steam in order to specify a flow direction and / or to atomize the binder.
  • the gluing of particles is a known process for a long time.
  • the handling of wood particles so for example chips or fibers is described, which may be previously produced in a defibrating device (refiner) and be pressed in a later process continuously or discontinuously as a particle mat to wood fiber boards.
  • binders which can be used for "gluing” are primarily isocyanates, methylene diphenyl isocyanates, urea formaldehydes, phenolic resins and the like. ⁇ . To understand.
  • the binder is understandably to all in the transport tube (also called blowline) conveyed particles are transmitted as evenly as possible. In addition, it should be avoided that the binder alone or with the particles can settle on the wall of the transport tube and thus changes the cross section, the flow velocity and the pressure in the transport tube.
  • the binder is introduced via a nozzle device with a velocity component directed counter to the main flow direction.
  • fibers can enter the nozzle during production interruption. The glue and / or the fibers in the nozzle can harden over heat and moisture, after which a cleaning of the nozzle is possible only through a costly disassembly.
  • the nozzle is guided and operated as far as the central axis of the transport tube (blow-line), there is also the risk that the binder will harden with time due to the temperature influence of the usually hot carrier medium before the nozzle outlet, thus clogging the nozzle as well ,
  • DE202008015419U1 discloses the features of the preambles of claims 1 and 4.
  • the invention therefore has the task of developing a method and a device for the gluing of particles, in which, with a uniform distribution of the binder on the particles, the period between the cleaning cycles can be significantly increased.
  • a spray from the primary nozzle is deflected by the particle flow and its carrier medium. Without the following secondary nozzle, emerges from the compressed air, steam or water in the direction of Bindeffensprühstrahls, the binder would possibly pressed with fibers to the transport tube wall and "cake" there. With the help of the jet from the spaced secondary nozzle, however, it is possible to evenly distribute the binder jet over the entire transport pipe cross section and in this way to reach and wet all the particles flowing in the transport pipe. In addition, it can be achieved by a desired even finer atomization of the binder.
  • An angle of 10 to 80 ° is set between the spray of the primary and secondary nozzles.
  • the exact angle depends on the flow rate, the transport volume, the pressure and the temperature in the transport tube. But it is possible to calculate the optimal angle or to find it by a model. The angle also determines the distance between the primary and secondary nozzles.
  • water it is preferable to use water as the coolant. And it is also preferred in many cases that a coolant exits the primary nozzle during operation with the binder.
  • the binder is to be diluted or even finely atomized.
  • the orientation of the primary nozzle is substantially perpendicular, d. H. ⁇ 20 ° to the flow direction.
  • the spray from the secondary nozzle is fan-shaped.
  • the primary nozzle has a cooling device.
  • annular channel is provided around the primary nozzle through which cold water can flow as coolant. This avoids that the high temperatures prevailing in the transport tube, transferred to the nozzle head of the primary nozzle and harden binders.
  • the coolant exits the primary nozzle during operation with the binder.
  • the binder spray can additionally be vortexed and / or diluted and / or atomized.
  • the primary nozzle is used as a two-substance nozzle.
  • the annular channel has one or more outlet openings to the nozzle outlet of the binder out, usually for water. In addition, so no separate return from the annular channel is necessary.
  • a needle provided with an actuator is present in the primary nozzle.
  • This movable needle allows piercing the nozzle orifice in the event that any material has yet settled there.
  • This needle can be used as a stopper at the outlet in cases where the spraying of binders must be interrupted.
  • the primary nozzle and the secondary nozzle are attached to a common holder.
  • the holder can then be detachably and sealingly secured to the transport tube with the two nozzles when the transport tube has the necessary openings for the spray jets. This arrangement allows for maintenance cases rapid replacement of both nozzles by a provided identical spare part.
  • the primary and the secondary nozzle are attached to an end portion of the transport tube, which is already inside a dryer.
  • the binder components are marked with small crosses, water is shown in dotted lines and steam is symbolized by black lines.
  • the particle streams 12 with the associated carrier medium, the heating gas flow 11 and the gas and water and particle flow 20 are marked only by the corresponding reference numerals.
  • Fig. 1 shows a curved tube 19 a drying device 2.
  • warm and dry exhaust gases so-called hot gases 11 flow at very high temperatures.
  • the straight transport tube 3 is in the outer Curvature introduced into tube 19 and held centrally with a fixing star 10, so that the guided over the transport tube gas, water and particle stream 20 enters the center of the dryer.
  • the fixation star 10 is in Fig. 2 showing a section through the curved tube 19 and the transport tube 3, clearly shown.
  • the holder 6 for the primary nozzle 4 and the secondary nozzle 5 is mounted on the transport tube 3.
  • the circular dashed outlined primary and secondary nozzle are in the description to Fig. 3 explained as subject matter essential to the invention.
  • the supply lines to the nozzles are indicated. It is the binder feed 7 and the water supply 8 to the primary nozzle 4 and the steam supply 9 to the secondary nozzle 5, wherein the secondary nozzle could alternatively be operated with compressed air or water.
  • Such a supply (7, 8, 9) is usually realized by pipes or hoses.
  • Fig. 3 shows in enlarged and sectional view the device 1 for gluing the wood particle stream 12 with the holder 6 for the primary nozzle 4 and the secondary nozzle 5, which in Fig. 1 circled dashed.
  • the nozzles 5 and 6 are shown cut.
  • the primary nozzle 4 has the nozzle opening 21.1, the secondary nozzle 5 the nozzle opening 21.2.
  • the primary nozzle 4 is at right angles to the particle flow 12. It sprays binder, for example isocyanate, into the transport tube 3, but does not reach into the tube. As a result, first, abrasion by the particle flow and, secondly, the entry of particles into the nozzle are avoided.

  • an annular channel 16 is arranged around the binder channel 15, which serves with the flow of a cooling medium, in this case water, down to the outlet 21.1 as a cooling device ,
  • a cooling medium in this case water
  • the water exits the primary nozzle 4 with the binder.
  • the binder can be better atomized and cooled in this way, because in the transport tube, the particle flow is often entrained by the carrier medium water vapor. This is hot and would cure the binder too early, so even before leaving the transport tube 3.
  • the exit of the water from the primary nozzle 4 is not decisive for the invention and the coolant can also be removed elsewhere.
  • the second separate and slightly spaced secondary nozzle 5 which is arranged in this example at 45 ° to the flow direction F, steam is sprayed through the steam channel 18 against the exiting binder / water spray jet 14.
  • the angle between the binder spray 14 and the steam jet 13 depends on many factors and can be fixed in experiments or calculations. In an intended particularly comfortable embodiment of the invention is also provided to make the angle adjustable via motors or actuators. In any case, it should be between 10 and 80 °.
  • the impact of the steam jet 13 on the exiting binder / water spray 14 has the consequence that the binder / water spray jet 14 is not directly back to the wall by the particle flow, which may have about 250 m / s speed of the transport tube is steered and "caked" there. Rather, causes the steam jet or possibly also a water jet 13 from the secondary nozzle 5, that the binder distributed evenly over the transport pipe cross-section and can wet all wood particles.
  • Fig. 4 is indicated that the favored design of the steam steel 13 is flat and fan-shaped.
  • the primary nozzle 4 is designed so that it can be pulled without great effort from the holder 6 for maintenance.
