Definitions

  • the invention relates to a device with a first and a second zone for the production of insulation or soundproofing panels from a pressed material mat, which at least partially consists of lignocellulosic particles wetted with binders, the first zone being designed to heat and / or compress the pressed material mat and the second zone is designed to harden the pressed material mat with the aid of calibration plates,
  • the invention further relates to a method for producing insulation or soundproofing panels from a pressed material mat, which at least partially consists of lignocellulosic particles wetted with binders, with the device mentioned.
  • a pressed material mat which at least partially consists of lignocellulosic particles wetted with binders.
  • Such a device has been published, for example, in DE 10 2008 039 720 B4.
  • such devices are equipped with pre-compression devices or after-pressing devices, e.g. B continuous presses, connected in series, but are not important in the context of the invention.
  • the products created on the device are offered, for example, by SOPREMA GmbH under the name Pavatex or H. Henselmann GmbH + Co KG under the name Gutex.
  • Suitable binders are those based on the principle of polycondensation or polyaddition, such as PMDI.
  • insulating boards with densities of 100-240 kg / m 2 should preferably be able to be produced.
  • the sieve belts or sieves for short serve to guide the pressed material mat through the device at a desired speed by driving it at the same speed as the mat is to be transported. Steam can be introduced into the pressed material mat from the outside through the sieve or liquid and air can be removed.
  • Screening belts are used, of which at least two are arranged in active contact with the pressed material mat in the area of the first zone and at least two of which are arranged in active contact with the pressed material mat in the area of the second zone.
  • the term active contact is also to be understood as such if a further circumferential porous belt runs between the material to be pressed and the sieve belt.
  • the inventors have recognized that the strain on the screen belt is particularly high in the area of compression or steam heating, that is to say in the first third of the overall device. For this reason, a separate sieve belt is used for the first zone on both sides of the material to be pressed, which can be driven independently of the sieve belts which act in the hardening area, that is to say the second zone.
  • the at least four sieve belts each have their own drive.
  • each sieve belt can be pushed to its maximum capacity.
  • the tension on the sieve belt can be recorded using suitable sensors and the results can be used in the drive control. In this way, the drive torques can be kept within a permissible range.
  • driven deflection rollers are used to drive the screen.
  • a device for steam application to the pressed material mat is provided in the first zone and a device for air cooling of the pressed material mat is provided at the end of the second zone.
  • the higher speed achievable with the invention allows higher productivity with slightly higher energy input or slightly increased device length.
  • This provides the energy required to harden the pressed material mat and its binding agent.
  • the pressure of the steam is designed so that it penetrates at least to the center of the material to be pressed and heats it. It can also be a steam-air mixture, in which case the dew point is also set
  • the moist air is preferably sucked off again or a vacuum is generated by means of a suction device in order to support the penetration depth of the steam into the pressed material mat and to reduce the curing time in the second zone. It is advantageous if there are at least two
  • the first zone which is called “vaporization zone” in the description below in order to simplify legibility, is generally somewhat shorter than the second zone, which is to be called the "curing zone”.
  • the air cooling ultimately serves the purpose of cooling the hardened pressed material mat to such an extent that no harmful processes, such as hydrolysis, can occur after exiting the device, which impair the plate quality.
  • the device preferably has a height-adjustable inlet.
  • the drive power required for the pressed material mat depends to a large extent on the thickness of the pressed material mat and its compression. Since customers want to change their production temporarily and the product thicknesses preferably fluctuate between 5 and 240 mm, an adjustment may be necessary in order to achieve additional compression or the distance
  • the calibration plates are preferably heatable plates.
  • calibration plates 3 are therefore arranged, which can be heated using different systems.
  • channels provided with heating fluid, inductive heating, electrical heating or steam heating are possible, the latter also being able to deliver the steam directly to the pressed material mat.
  • the curing process of the binder can be accelerated, so that the length of the device is kept within reasonable limits.
  • the first and second zones are preferably immediately adjacent to one another.
  • the shoe has a flat sliding surface facing the pressed material mat and its side walls are shaped in such a way that
  • the object of the invention is achieved by the features of claim 8 and in particular in that at least four rotating sieve belts are used, at least two of which act on the material to be pressed in the region of the first zone and of which at least two are in the region of the second zone act on the pressed material mat.

  • a material to be pressed which at least partially consists of lignocellulosic particles wetted with binders, is treated in a first zone Z1 and a second zone Z2 between an upper circulating sieve belt 5a and a lower circulating sieve belt 5d.
  • the separation of the zones is indicated in all figures by a dash-dotted vertical line.
  • the pressed material mat was heated with steam or a steam-air mixture within the upper and lower sieve circulation and finally hardened by applying heat via calibration plates. Speeds could only be shown up to the tensile strength limits of the sieves.

  • the designations 5b and 5c In the upper part of the device they have the designations 5e and 5f. All rotating sieve belts 5a - 5f have their own drive, which is realized via the driven deflection rollers 8.
  • this zone Z1 receives two separate rotating sieve belts which are driven separately. This reduces the tensile load on the long surrounding sieves 5a and 5d.
  • zone Z2 in which the pressed material mat 2 hardens.
  • a separate rotating and driven screen belt 5c, 5f is provided both above the pressed material mat 2 and below, which provides part of the transport service. Overall, significantly higher speeds can be achieved with this arrangement.

Since steam penetrates through the surrounding sieves 5a and 5b or 5d and 5e into the pressed material mat 2 and condenses. Escaping residual steam and residual air can be removed via the suction devices 6a and 6b.

Abstract

L'invention concerne un dispositif et un procédé, le dispositif comprenant une première et une deuxième zone (Z1, Z2), pour produire des plaques isolantes ou des plaques insonorisantes à partir d'un mat de matière pressée (2) constitué, au moins en partie, de particules lignocellulosiques enduites de liants. La première zone (Z1) est conçue pour chauffer et/ou compacter le mat de matière pressée, et la deuxième zone (Z2) est conçue pour faire durcir ce mat de matière pressée au moyen de plaques de calibrage (3), des bandes filtrantes (5a-5f) rotatives entraînées en contact avec la surface supérieure et la surface inférieure du mat de matière pressée étant prévues. L'objectif de cette invention est d'accroître la vitesse de production. À cet effet, au moins quatre bandes filtrantes (5a-5f) rotatives sont employées, au moins deux de ces bandes étant agencées dans la région de la première zone (Z1) en contact fonctionnel avec le mat de matière pressée (2) et au moins deux de ces bandes étant agencées dans la région de la deuxième zone (Z2) en contact fonctionnel avec le mat de matière pressée (2).
