Abstract
Description
Die Erfindung betrifft ein Verfahren zum Verbrennen
von schwer verbrennbarem Material, wobei das Material
in einer Brennkammer eines Ausbrennofens unter Zufuhr
von Luft verbrannt wird. Die Erfindung betrifft auch
eine Vorrichtung zum Verbrennen von schwer verbrennbarem
Material gemäß dem Oberbegriff von Anspruch 9.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
In Ausbrennofen werden Modelle aus Wachs oder gesinterte Teile, eingebettet in Gips, Sand oder Keramik bei einer hohen Temperatur ausgeschmolzen und der verbleibende Rest mit einer noch höheren Temperatur (über 600 °C verbrannt. Dies geschieht durch die Verbrennung mit Luft in einer chemischen Reaktion.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.
Derartige Ausbrennofen werden beispielsweise in der Schmuckindustrie oder im Gießereibedarf eingesetzt, wobei Wachs und Giesharz gebundene Werkstoffe, die in Sand, Keramik oder Gips eingebettet sind, ausgebrannt werden.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.
Bei den bisher gebauten Brennöfen findet größtenteils eine unvollständige Verbrennung der eingebetteten Modelle (z.B. Wachs) statt. Dabei entstehen Rauch und Verkohlung des Restmaterials. Das verkohlte Material wird durch den Rauch nach außen getrieben und setzt sich teilweise in der Brennkammer und auch in den Formen fest.Most of the kilns built so far take place incomplete combustion of the embedded models (e.g. wax) instead. This creates smoke and Charring of the residual material. The charred material is driven out by the smoke and sets partly in the combustion chamber and also in the forms firmly.
Der durch das verkohlte Material entstehende Rauch belastet die Umwelt. Dieses Problem wird meist durch den - kostspieligen - Einsatz eines Katalysators eingeschränkt.The smoke created by the charred material is contaminated the environment. This problem is mostly caused by the - costly - limited use of a catalyst.
Das weitaus größere Problem besteht darin, daß das verkohlte Material auf den Keramik-, Gips-, oder Sandformen haften bleibt. Es verhindert die vollständige Leerung des Hohlraumes, der zum Gießen von Metallen nötig ist. Es verbindet sich außerdem mit der Schmelze und den gegossenen Teilen und führt somit zu einer schlechten Oberfläche und Fehlerbildungen der Gußteile.The far bigger problem is that the charred material on the ceramic, plaster, or sand molds sticks. It prevents the complete Emptying the cavity used for casting metals is necessary. It also combines with the melt and the cast parts and thus leads to one poor surface and defects in the castings.
Aus der Praxis sind Versuche bekannt, durch eine höhere Luftzufuhr, die Verkohlung zu verhindern oder durchzuspülen. Experiments are known from practice, by a higher Air supply to prevent charring or flush.
Viele Materialien, besonders gesinterte Teile und harzgebundene Werkstoffe, verkohlen, trotz Luftzufuhr, durch den entstandenen Temperatur-Schock, anstatt vollständig zu verbrennen.Many materials, especially sintered parts and resin-bound materials, charring, despite air supply, through the resulting temperature shock instead burn completely.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Verbrennen von schwer verbrennbarem Material mittels einem Ausbrennofen zu schaffen, wobei eine annähernd rauchfreie und rückstandslose Verbrennung des Materiales, möglichst bei niedrigen Temperaturen, vorzugsweise in kurzen Brennzyklen erzielt werden soll.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.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die der Brennkammer des Ausbrennofens zugeführte Luft ionisiert wird.According to the invention this object is achieved in that the air supplied to the combustion chamber of the burnout furnace is ionized.
Erfindungsgemäß wird diese Aufgabe auch durch den
kennzeichnenden Teil des Anspruchs 9 gelöst.According to the invention, this object is also achieved by the
characterizing part of
Dadurch, daß die der Brennkammer zugeführte Luft ionisiert ist, ergibt sich, wie sich in umfangreichen Versuchen gezeigt hat, eine rauchfreie und rückstandslose Verbrennung des schwer verbrennbaren Materiales. Dies ist bereits bei Temperaturen von nur maximal 650 °C möglich. Darüber hinaus können kurze Brennzyklen durch einen, aus der ionisierten Luft resultierenden, schnellen Reaktionsbeginn bereits beim Aufheizen erzielt werden. Because the air supplied to the combustion chamber ionizes is the result of extensive tests has shown a smoke-free and residue-free Burning the difficult to burn material. This is already at temperatures of only a maximum of 650 ° C possible. In addition, short firing cycles can go through a resulting from the ionized air rapid reaction start already achieved when heating up become.
Durch die Ionisiation werden Sauerstoffmoleküle (O2) in ein Ion umgewandelt, es entsteht Ozon (O3). Das entstandene Ozon ist ein instabiles Ion und wird sehr schnell in das Molekül (O2) und das Atom (O) gespalten.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).
Das Ozon ist ein aggressives Gas, daß sich sehr schnell zerlegt. Das frei werdende O-Atom verbindet sich mit anderen O-Atomen zu einem Sauerstoffmolekül. Allerdings bevorzugen die O-Atome eine chemische Reaktion mit fremdem Material, besonders mit Kohlenstoff (C) und Kohlenmonoxid (CO). Dadurch entsteht ein Zwang zur vollständigen Verbrennung.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. However, the O atoms prefer a chemical reaction with foreign material, especially carbon (C) and carbon monoxide (CO). This creates a compulsion for complete combustion.
In vorteilhafter Weise führen somit die schwer verbrennbaren Materialien gezwungenermaßen zu einer chemischen Reaktion. Das Ergebnis ist eine saubere Verbrennung ohne Rauchbildung in der Form und in der Brennkammer. Die Brennergebnisse sind rückstandsfrei und benötigen nur einen geringen Energieverbrauch. Darüber hinaus werden Kohlenstoffniederschläge bzw. Ablagerungen in der Brennkammer vermieden. Daher ist keine geschlossene Heizspirale notwendig und es kann eine offene Heizspirale eingesetzt werden.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. In addition, 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.

Die durch das 3D-Inkjet-Verfahren erzeugten Modelle können für den Modellfeinguß direkt in Gipsformen eingebettet werden. Bei diesen Verfahren bestehen die Modelle aus schwer verbrennbarer, mit Wachs oder Harz infiltrierter Stärke/Zellulose. Nach umfangreichen und langwierigen Versuchen bei verschiedenen Temperaturen ist es dabei gelungen, die Modelle restlos in der Form bei niedrigen Temperaturen von maximal 650 °C rauchfrei zu verbrennen. Die Möglichkeit, die Modelle aus Stärke-Material rauchfrei und ohne Rückstände auszubrennen, verringert die Durchlaufzeiten und verbessert die Qualität der Teile erheblich.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.
Von Vorteil ist es, wenn die Menge der der Brennkammer zugeführten, ionisierten Luft mittels einer Luftdurchflußregeleinrichtung kontrolliert wird.It is advantageous if the amount of the combustion chamber supplied, ionized air by means of an air flow control device is checked.
Wie sich in Versuchen herausgestellt hat, läßt sich durch eine Luftdurchflußregeleinrichtung der Verbrennungsprozeß in besonders vorteilhafter Weise steuern. Somit kann eine minimale aktivierte Luft (ionisiert) in die Brennkammer des Ausbrennofens geführt werden.As has been shown in experiments, the combustion process by means of an air flow control device control in a particularly advantageous manner.
