Definitions

  • the invention relates to a device for drying wood with a chamber for receiving the wood.
  • Wood to be dried is placed in a container and dried by means of a heated stream of air.
  • ambient air is introduced from outside and heated and passed through the container.
  • the heated air also heats the wood so that water inside it evaporates and is transported out of the tank with the air. Due to the need to heat air and direct it through the containers via a blower or the like, a high thermal or mechanical effort is currently required for drying wood in such devices.
  • heated by heated air it can also come to a purely near-surface heating, which can lead to a closure of near-surface voids in the wood.
  • the object of the present invention is therefore to reduce the effort required to dry wood.
  • an apparatus for drying wood comprising: a container for receiving the wood,
  • a plate forming a wall of the container, wherein the plate is heatable and wood at least partially rests against the plate.
  • the wet, to be dried wood can be arranged and removed after the drying process.
  • the heat required to dry the wood can be introduced through the plate.
  • the ambient air may be cold air supplied from outside.
  • An advantage of this method is seen in that the heat is transferred via heat radiation from the plates to the wood. This warms the wood evenly. The heated air is discharged as soon as it has reached a high relative humidity and can absorb little or no further water. To speed up the drying process can
  • Circulating fans be provided.
  • the drying process is shortened in time by about 30 to 40%.
  • tubes on the plate which are fluid-conductively connectable to a heating device.
  • the heater may be, in particular, one with wood or
  • An underlying idea of the invention is to improve the sustainability of wood as an energy source, while considering the overall efficiency from deforestation to combustion at the customer. If, for example, other energy carriers and / or high amounts of electrical power have to be used to dry the wood, these must be included in the total balance. By using wood residues and wastes to dry wood, which can not be sold anyway, the sustainability of wood as an energy supplier can be improved overall.
  • the tubes are connected via a weld with the plate.
  • the tubes are each connected to the plate via two welding beads running on both sides on the tubes and parallel to the tubes.
  • the weld beads thus provide a cohesive connection between the plate and an outside of the tubes so that a large heat transfer from the tubes to the plates is made possible.
  • the container is at least partially tiltable.
  • the container with the wood contained therein can be tilted in total to the wood after drying easier from the
  • the plates can be pivoted from a horizontal position into a tilted position.
  • the plates can be pivoted to the removal of wood from the container in the tilted position, after which the wood can be removed by suitable means from the container.
  • a conveyor for conveying wood from the container is arranged below the plate, wherein lying on the plate wood slips in the tilted position on the conveyor. The conveyor allows removal of dried wood from the container. The drying process can thus be partially automated.

  • the plurality of superimposed plates may be pivotally mounted in the container as described above and / or pulled horizontally out of the container via the previously described actuator. Accordingly, to fill the container with wood to be dried first lower plates are loaded and successively the plates lying further up. To unload the container, the plates lying further down can first be pulled out, whereupon the dried wood can be removed from the container at the bottom by suitable means.
  • a conveyor is arranged in the container for unloading the container, wherein the plates are arranged opposite to the conveyor so that wood located on the plates falls upon withdrawal of the plates on the conveyor.
  • the conveyor may be, for example, an endless belt, for example a widened metal chain and / or a textile or Rubber band. This conveyor allows a quick and
  • Drying plants which heat the wood with heated air. By heating the air to lower temperatures, it can absorb the moisture contained in the wood well.
  • the introduction of heat via the plate takes place during a heating phase, which extends over a period of one to six days, in particular between one and four days.
  • the venting of the container is preferably carried out during a drying phase, which extends over a period of one to ten days, in particular between two and eight days.
  • ambient air can be supplied discontinuously, for example at intervals of about 10 minutes, in order to force the water laden air out of the container and to absorb further moisture.
  • the ambient air can be previously heated as described in the previous paragraph.
