Definitions

  • the invention relates to a method for burning of flame-retardant material, the material in a combustion chamber of a burnout furnace with feed is burned by air.
  • the invention also relates a device for burning combustible Material according to the preamble of claim 9.
  • Models in wax or sintered are used in the furnace Parts embedded in plaster, sand or ceramic melted out at a high temperature and the remaining Rest with an even higher temperature (above 600 ° C burned. This happens through the combustion with air in a chemical reaction.
  • Such burnout furnace are, for example, in the Used in the jewelry industry or in foundry needs, where wax and cast resin bound materials, which in Sand, ceramics or plaster are embedded, burned out become.
  • the present invention is based on the object a method and an apparatus for burning difficult to burn material by means of a burn-out furnace to create an almost smoke - free and residue-free combustion of the material, if possible at low temperatures, preferably in short Firing cycles should be achieved.
  • this object is achieved in that the air supplied to the combustion chamber of the burnout furnace is ionized.
  • Ionization converts oxygen molecules (O 2 ) into an ion, which creates ozone (O 3 ).
  • the ozone formed is an unstable ion and is very quickly split into the molecule (O 2 ) and the atom (O).
  • the ozone is an aggressive gas that is very quickly disassembled.
  • the released O-atom connects with other O atoms to form an oxygen molecule.
  • the O atoms prefer a chemical reaction with foreign material, especially carbon (C) and carbon monoxide (CO). This creates a compulsion for complete combustion.
  • the difficultly combustible lead in an advantageous manner Materials are forced to a chemical Reaction.
  • the result is clean combustion without smoke in the form and in the Combustion chamber.
  • the firing results are residue-free and only need a low energy consumption.
  • carbon precipitation or Deposits in the combustion chamber avoided. thats why no closed heating coil necessary and it can an open heating coil can be used.
  • the Method according to the invention all known 3D models made of polystyrene, polystyrene (SLS), STL materials, Thermopolymers and even those infiltrated with wax or resin Starch / cellulose for metal investment casting directly embedded in plaster, ceramic or sand and at Temperatures around 600 ° C are burned out without residue.
  • each difficult to burn material at low temperatures can be burned out smoke-free from a maximum of 650 ° C.
  • inventive method and the inventive Prototype can be made of metal inexpensively and in a particularly simple manner of excellent quality.
  • the inventive method and the inventive Device can be particularly advantageous can be used for the well-known 3D inkjet process.
  • the models created by the 3D inkjet process can be used for model investment casting directly in plaster molds be embedded. Pass through these procedures the models made of flame retardant, with wax or Resin infiltrated starch / cellulose. After extensive and lengthy trials at different temperatures the models were completely successful in the mold at low temperatures of maximum 650 ° C to burn smoke-free.
  • the possibility of the models Made of starch material, smoke-free and without residues burnout reduces lead times and improves the quality of the parts considerably.
  • the air flow control device By the air flow control device, the conditioned air is controlled in the combustion chamber of the Bring the burnout furnace.
  • the Air before being fed into the combustion chamber by means of a Air ionization device is ionized.
  • Air ionization device The ionization of the air by a known principle Air ionization device has been in trials turned out to be particularly suitable and inexpensive.
  • the inventive method and the inventive Device are based on the in the first and 2 illustrated principle explained in principle, however, are not limited to this.
  • the one in Fig. 1 Burnout furnace 1 shown is particularly suitable for the production of prototypes from metal.
  • the stake such a burnout furnace 1 or the burnout However, difficult to burn material various other, obvious to the expert Reasons.
  • Burnout furnaces can be of different designs, for example as a chamber, slide-in car or hood oven be trained.
  • the burnout furnace 1 as shown in FIG. 1, ionized air supplied through an air inlet 2, those in the combustion chamber of the burnout furnace 1 for one complete and smoke-free combustion of the heavy combustible material leads.
  • the ionized Air through a heat exchanger 3 below Tool 4 blown in.
  • the tool 4 is the expert common and therefore not shown in detail.
  • an air ionization device 5 Through the air ionization device 5 the air ionization device 5 is supplied Air is converted from the molecular to the ionic state. Then the ionized air enters the air 2 of the burnout furnace 1 supplied.
  • Fig. 1 is an air flow control device 6 for the metered supply of Air provided. It can thus be done in a simple manner the amount of fuel fed into the combustion chamber Air ionization device 5 Check ionized air. The combustion in the burnout furnace 1 or the combustion chamber can be controlled by the air flow control device 6 or the supplied ionized air Taxes.
  • the air flow control device 6 in the direction of flow Air arranged so that the air flow control device 6 in front of the air ionization device 5 happens.
  • the air flow control device 6 can also between the air ionization device 5 and the Burnout furnace 1 may be arranged.
  • the Air flow control device 6 with an air pressure regulator 7 and a flow indicator 8 is formed.
  • the compressed air is controlled by the air pressure regulator 7, which can also be called a maintenance unit, controlled or regulated.
  • the air pressure regulator 7 will through an air pressure regulator input 9 with compressed air provided.
  • the air ionizer 5 for conversion of oxygen from the air in ozone a component of the burnout furnace 1.
  • the air flow control device 6, the combustion chamber, and the air ionization device 5 components of the burn-out furnace 1.
  • the use of the air ionization device is particularly advantageous 5 with the air flow control device 6, which the air flow into the burnout furnace 1 controlled and thus a smoke-free and residue-free Burn the material in a particularly suitable way Way.
  • the air ionization device 5 for ionizing the Air and the air flow control device 6 can as separate from the burnout furnace 1 or the combustion chamber and thus connectable unit are formed. This ensures that this unit to everyone Burnout furnace 1 can be connected or retrofitted can. By burning residual gases and vapors this system also serves as a catalyst.
  • the combustion chamber also be designed as a gas furnace. The combustion process in the combustion chamber is complete Combustion carried out.
  • Fig. 2 shows an air ionization device known in principle 5.
  • the air ionization device 5 consists of a safety switch 10, one Current control unit 11, a high voltage transformer 12, an air pressure vessel 13, ionizing plates 14 and an air inlet 15 and an air outlet 16. Since such air ionization devices 5 in principle are known, this will not be discussed in more detail.
