Definitions

  • the invention relates to a device for discharging laterally from a continuous press for the production of wood-based panels exiting wood chips or other wood particles, wherein the press in each case has a press nip circulating upper belt and lower belt, which can be pressed by means of at least partially heated pressure plates against a wood fiber material.
  • the invention further relates to a method for discharging laterally from a continuous press for the production of wood-based panels exiting wood chips or other wood particles, the press each having a press nip circulating upper belt and lower belt, which are pressed by means of at least partially heated pressure plates against a wood fiber material.
  • the resulting gas pressure causes that Wood chips or other wood particles are ejected laterally out of the press nip.
  • the object is achieved by the features of claim 1 and in particular in that the side of the press nip at least in an end portion of the press a collecting funnel arrangement for the wood chips or other wood particles is arranged, which forwards them to a mechanical transport device.
  • the transport device is formed by at least one transport screw.
  • the collecting funnel arrangement can have a longer shape in the direction of passage of the press.
  • the chips discharged through the collecting funnel arrangement fall from above into the transport screw opened at the top and are transported away, preferably also parallel to the direction of passage of the press.
  • transport screws are arranged one above the other and partially overlapping in the transport direction.
  • an upper transport screw can transfer the transported chips to a lower transport screw.
  • this arrangement it is possible to use shorter feed screws, so that the drives can be made smaller than when only a single screw conveyor over the entire desired transport length is used.
  • the suction device has no suction effect on the press nip between the upper and lower band, so that the wood fiber material is not removed at the edges.
  • the catcher assembly consists of several funnels in the vicinity of the press nip, the length of which is dimensioned to fit individually or in a group just between frames of the continuous press.
  • the cascaded frames of the continuous press are, as the case may be, laterally beyond the press belts that circulate within the frame. Accordingly, it is advantageous if the individual funnels of the funnel arrangement fit exactly between the frames, because they are thereby brought close to the press nip and can cover the entire outwardly open press nip length.
  • the term "proximity" is here to understand a distance of 5 to 200 mm.
  • the hopper assembly and the transport means form a prefabricated unit.
  • the assembly and disassembly is simplified. With a hall crane, the entire unit is movable and interchangeable for maintenance purposes.
  • the assembly is advantageously movable transversely to the direction of passage of the continuous press.
  • the assembly of a hopper assembly and a transport device for example, on rails in the hall floor be movable. It may, for example, be in a first end position with the funnel opening in the vicinity of the press nip and moved so far away in a second end position of the continuous press that maintenance on the entire system is easier to perform.
  • supply pipes running laterally on the longitudinal side of the continuous press are arranged either below the hall floor or above the press nip.
  • the installation of the collecting funnel arrangement and the transport device is significantly simplified. And in particular they can be moved unhindered as a unit.
  • the object of the invention with the features of claim 9 is achieved and in particular the fact that the side of the press nip is arranged at least in an end portion of the press a catching funnel arrangement for the wood chips or other wood particles, with this catcher arrangement the wood chips or other wood particles are collected be forwarded to a mechanical transport device and transported with the transport device.
  • FIG. 1 and 2 show the same system with a continuous double belt press 2 and the device 1 according to the invention from two different viewing directions, as a cross section and as a side view.
  • Fig. 2 can be seen the end of a continuous double belt press 2 with a circumferential upper belt 3 and a revolving lower belt 4.
  • Upper belt 3 and lower belt 4 form a press nip 5 in which a wood material 6, consisting of at least a large part of wood chips or other wood particles is pressed.
  • the pressing process takes place via upper pressure plates 7 and lower pressure plates 8, of which at least one by hydraulic pressure cylinder 9, for example, with the interposition of rolling elements, not shown against at least one circulating belt 3, 4 are pressed and thus close the press nip 5 and act on the wood material 6 ,
  • the pressure cylinders 9 are attached, for example, to individual frame 13 and are supplied for example from a hydraulic station 10 with pressure oil. Their pressures across the width and length of the continuous press from cylinder to cylinder can vary and be separately adjustable.
  • the lower strand of the upper belt 3 and the upper strand of the lower belt 4 form within the frame 13 the press nip 5 and are guided by guide rollers 14 deflected finally returned above or below the frame 13.
  • the heated pressure plates 6, 7 are usually supplied along along the continuous press feeds 11 and stub lines 12 with a heating medium, such as fuel oil, which passes through introduced into the pressure plate 7, 8 channels and thus the press nip 5 and der Holzwerkstoff 6 additionally heated.
  • a heating medium such as fuel oil
  • the water contained in the wood material 6 evaporates, and the vapor pressure drives wood chips laterally out of the press nip, which without the inventive device 1 can lead to large pollution and hazardous way even to the combustion of the fibers to the supply lines for the heating medium.
  • the device 1 has a collecting funnel arrangement 15 with individual funnels 16 between the frames 13.
  • the funnels forming the funnel may have maintenance flaps 17.
  • the funnels are designed so that the chips blown laterally out of the press nip 6 are fed directly to a mechanical transport device 18, in this embodiment a screw conveyor 19.1, 19.2. In these screw conveyors 19.1, 19.2, the chips are transported to a suction device 20. At the end of the press, a suction device no longer has any harmful influence on the side edges of the wood-based material 6.
  • FIGS. 1 and 2 are two screw conveyors 19.1 and 19.2 arranged one above the other and overlapping.
  • the screw conveyor 19.1 transfers the conveyed material to screw conveyor 19.2, which also at the same time the discharged chips from the last section of the Collecting funnel arrangement 15 receives. By shortening a possible long screw to two shorter, the space for the drives can be reduced.
  • the screw conveyor 19.2 transfers the discharged chips to the suction device 20.
  • the screw conveyors 19.1, 19.2 and the hopper assembly 15 form on each side of the continuous double belt press 2, a common unit 21 which can be moved on rails 22 on the hall floor 23 and thus more or less spaced from the continuous double belt press.
  • a clearance for maintenance work can be created.
  • the assembly 21 is in Fig. 1 drawn on the right side in two different end positions E1 and E2.
