Definitions

  • the invention relates to a dryer for sheet materials, in particular sheets, films or foils.
  • the invention also relates to a method for drying such flat materials.
  • a device for treating webs for example plastic films
  • the device is intended to heat the web and, in the case of a plastic film, then stretch it, for example, in order to achieve an alignment of the polymer molecules in the web.
  • the device has a plate made of a gas-permeable material such as sintered metal, especially sintered bronze.
  • a treatment gas is conveyed through this sintered material.
  • the web is guided along above the plate and is kept at a distance from the sintered metal plate by the gas flow which passes through the sintered metal.
  • the sintered metal used is said to have a porosity of about 27%.
  • a dryer for treating a coated strip of material which is provided with numerous guide elements which have a gas guide surface facing the strip of material.
  • the gas guide surface is a side surface of an air-permeable body, which consists for example of sintered metal or porous glass.
  • the material strip is held at a distance above the guide surface by an air flow passing through the gas guide surface.
  • the invention is intended to provide an improved dryer for sheet materials and an improved method for drying sheet materials, with which even extremely sensitive sheet materials, for example very thinly coated plates or sensitive, in particular coated films or foils, can be obtained quickly and in an extremely gentle manner let dry.
  • a dryer for flat materials in particular plates, films or foils with the features of claim 1 and a method with the features of claim 8 is provided for this purpose.
  • a porous, gas-permeable metal plate is provided for arrangement at a distance from the flat material to be dried, means for conveying a gaseous fluid through the metal plate and wherein the metal plate consists of a metal foam.
  • the metal plate made of porous, gas-permeable metal foam that is to say open-pore metal foam
  • an extremely uniform flow distribution of the gaseous fluid on the flat material to be dried can be achieved.
  • a porous, gas-permeable metal plate made of open-pore metal foam above all locally higher flow velocities, which inevitably lead to an uneven drying process of the flat material to be dried, can be completely avoided.
  • the invention enables a uniform flow velocity and uniform flow conditions to be set over the entire surface of the flat material to be dried, so that extremely uniform and material-friendly drying can also be achieved.
  • the means for conveying a gaseous fluid have suction means for sucking gas from a region between the metal plate and the sheet material to be dried.
  • Particularly gentle drying can be achieved by sucking in gas from the area between the metal plate and the sheet material to be dried, since no flow is directed at the sheet material to be dried, but only a flow is generated away from the sheet material to be dried.
  • gas flows laterally into the space between the flat material to be dried and the metal plate, which then, in order to achieve a uniform flow distribution, advantageously also flows through a metal plate made of an open-pore metal foam.
  • the negative pressure can also be set so low that only insignificant Flow in quantities of gas and essentially only gases or vapors escaping from the flat material to be dried are extracted.
  • the metal plate can be inclined from the metal foam to the sheet material to be dried be arranged.

  • a suction effect can be generated by means of the so-called Venturi effect.
  • the gaseous fluid which can be, for example, nitrogen, a noble gas or another suitable gas, is guided past the surface of the metal plate that faces away from the flat material to be dried. A relatively high flow rate is preferably achieved.
  • the gaseous fluid then flows past the many open pores in the open-pore metal foam. This creates a suction effect through the so-called Venturi effect, through which gas, which is located in the space between the metal plate and the flat material to be dried, i.e. the drying space, is sucked out through the pores of the metal foam. This happens evenly over the entire surface of the metal plate, since the metal plate has open pores over its entire surface. In the drying space between the metal plate and the flat material to be dried, essentially constant flow conditions can be generated over the entire surface.
  • a plurality of flow spaces are arranged in the longitudinal direction of the material to be dried.
  • different flow velocities can be set in the flow spaces.
  • the flow velocity in a flow space in which the drying process is only just beginning is set very low in order to treat the liquid or gel-like sheet material in a particularly gentle manner and to draw in only a little gas from the drying space.
  • a very high flow rate can also be set in such a front flow space in order to accelerate the drying process, especially at the beginning.
  • Flow spaces that lie above flat material that has already been pre-dried can then be adjusted in such a way that an ideal negative pressure in the drying space is set for the material to be dried.

  • the strip-shaped or rod-shaped strip can thus consist of a metal foam strip or also of a tubular rod made of metal foam.
  • the lock gas can be introduced into the interior of the rod and then exits to the outside through the metal foam. Areas of the outer surface of the rod that face away from the material to be dried can be sealed. Such sealing can be effected by grinding the metal foam, but also, for example, by applying a sealing compound, for example an adhesive.
  • the metal foam consists of a stainless steel, in particular of chrome-nickel-stainless steel.
  • the metal foam can be made very corrosion-resistant and can also be used in corrosive environments. This is also essential so that corrosion products of the metal foam do not fall from the metal foam onto the material to be dried and thereby contaminate it.

  • the metal foam advantageously has carbon, copper, iron, molybdenum, manganese, phosphorus and / or zinc, in each case with a percentage of less than 1%.
  • the metal foam has a porosity of 90% or more.

  • the method according to the invention can also be operated in a so-called batch mode are used, so that the material to be dried is immovably arranged under the dryer.
  • Such a batch operation can be used for research purposes, but also when, for example, coated glass plates are to be dried and a continuous drying operation is not absolutely necessary.
  • the suction of gaseous fluid through the metal plate is provided from an area between the sheet material and the metal plate.

This gas is then discharged through the plate 26 together with the gas flowing through the flow space 22.
