Abstract

PCT No. PCT/DE82/00132 Sec. 371 Date Sep. 30, 1982 Sec. 102(e) Date Sep. 30, 1982 PCT Filed Jun. 22, 1982 PCT Pub. No. WO83/00209 PCT Pub. Date Jan. 20, 1983.A hot bulb ignition head for a device for firing rough ceramics, particularly bricks, serves the intermittent delivery of solid fuel by using compressed air. An explosion takes place in the hot ignition head, which leads to the ejection of the granular solid fuels, particularly coal, into the kiln chamber. It includes a cylindrical head portion with a baffle plate at the outlet end which forms outlet openings. The size of the outlet openings can be adapted to different kiln conditions by insertion pieces.

Description

Die Erfindung betrifft einen Zündglühkopf für eine Vorrichtung zum Brennen von Grobkeramik, insbesondere von Ziegeln, mit einem Anschlussrohr für die intermittierende Zufuhr von Festbrennstoff durch Druckluft, einem damit fest verbundenen zylindrischen Rohrendstück mit grösserem Durchmesser und einer Prallplatte am Austrittsende, die wenigstens zwei Austrittsöffnungen bildet.The invention relates to a glow plug for a device for firing heavy ceramics, in particular bricks, with a connecting pipe for the intermittent supply of solid fuel by compressed air, a cylindrical pipe end piece with a larger diameter and a baffle plate at the outlet end that forms at least two outlet openings.

Ein derartiger Zündglühkopf ist bereits aus der DE-PS Nr. 2441680 bekannt. Bei diesem bekannten Zündglühkopf ist die Verteilung des ausgeschleuderten Festbrennstoffes nur in eine bestimmte Richtung nicht gegeben. Auch ist die Gefahr der Zerstörung des Zündglühkopfes durch die auftretenden Explosionen nicht völlig ausgeschaltet und schliesslich ist keine Anpassungsmöglichkeit der Brennstoffverteilung an unterschiedliche Ofengegebenheiten möglich.Such an ignition glow head is already known from DE-PS No. 2441680. In the case of this known ignition glow head, the distribution of the ejected solid fuel only in one direction is not given. The danger of the ignition head being destroyed by the explosions occurring is also not completely eliminated and, finally, it is not possible to adapt the fuel distribution to different furnace conditions.

Der Erfindung liegt die Aufgabe zugrunde, den bekannten Zündglühkopf dahingehend zu verbessern, dass eine verbesserte Brennstoffausschleuderung in gewünschten Richtungen ermöglicht und die Gefahr der Zerstörung bzw. Beschädigung des Zündglühkopfes durch die auftretenden Explosionen vermieden wird.The invention has for its object to improve the known ignition glow head in such a way that improved fuel ejection in desired directions and the risk of destruction or damage to the ignition glow head due to the explosions occurring is avoided.

Die Erfindung löst diese Aufgabe mit den kennzeichnenden Merkmalen des Anspruches 1, wobei zweckmässige Ausgestaltungen in den abhängigen Ansprüchen wiedergegeben sind.The invention solves this problem with the characterizing features of claim 1, expedient configurations being given in the dependent claims.

Dadurch, dass der Zündglühkopf mit Rückschlagkammern ausgestattet ist, können auch auftretende stärkere Explosionen gefahrlos beherrscht werden. Die einander gegenüberliegenden Austrittsöffnungen mit ihren Lenkflächen und Lenkkammern gewährleisten eine gezieltere Ausschleuderung des granulierten Festbrennstoffes. Schliesslich ermöglichen die Einlegeteile eine einfache und rasche Anpassung des Brennvorganges an unterschiedliche Brennbedingungen, wie z.B. Ofenquerschnitte und dergleichen. Ausserdem sind die Zündflächen für den Brennstoff erheblich vergrössert, so dass eine wirksamere Explosion erzielbar ist.The fact that the ignition glow head is equipped with non-return chambers means that even strong explosions can be controlled safely. The opposing outlet openings with their steering surfaces and steering chambers ensure a more targeted ejection of the granulated solid fuel. Finally, the inserts enable simple and rapid adaptation of the firing process to different firing conditions, e.g. Oven cross sections and the like. In addition, the ignition areas for the fuel are considerably enlarged, so that a more effective explosion can be achieved.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnung zeigt:

Der in Fig. 1 dargestellte Zündglühopf 1 weist ein zylindrisches Anschlussrohr 2 auf, über welches der Zündglühkopf an eine Zufuhrvorrichtung anschliessbar ist, die dem im Ofeninneren befindlichen Zündglühkopf intermittierend Festbrennstoff, z.B. in Form von gemahlener Kohle, unter Anwendung von Druckluft zuführt. Zugeführte Brennstoffmenge und Druckluft sind dabei im Wert so bemessen, dass im Zündglühkopf eine Explosion entsteht, durch welche die Festbrennstoffteilchen aus dem Zündglühkopf geschleudert und über den Ofenquerschnitt verteilt werden.The ignition glow plug 1 shown in Fig. 1 has a cylindrical connecting pipe 2, via which the ignition glow head can be connected to a supply device which intermittently releases solid fuel, e.g. in the form of ground coal, using compressed air. The amount of fuel and compressed air supplied are dimensioned such that an explosion occurs in the ignition glow plug, by means of which the solid fuel particles are thrown out of the ignition glow plug and distributed over the cross section of the furnace.

Mit dem Anschlussrohr 2 ist ein zylindrisches Rohrendstück 3 fest verbunden, dessen Innendurchmesser grösser ist als der Innendurchmesser des Anschlussrohres 2. Am Anschlussende ist hierzu das Rohrendstück 3 mit dem Anschlussrohr 2 gegebenenfalls unter Einsetzen eines Stirnringes 4 verschweisst.A cylindrical pipe end piece 3, the inside diameter of which is larger than the inside diameter of the connecting pipe 2, is firmly connected to the connecting pipe 2.

Mit der Innenwand des Rohrendstückes 3 sind einander gegenüberliegend zwei ebene, stegartige Platten 5,6 fest verbunden. Hierzu sind die Längsränder 7 der Platten 5, 6 mit der Innenwand des Rohrendstückes 3 verschweisst. Zwischen Platten 5, 6 und der Innenwand des Rohrendstückes 3 bilden sich Kammern 8, die zum Ende des Anschlussrohres 2 hin offen sind.Two flat, web-like plates 5, 6 are fixedly connected to one another with the inner wall of the pipe end piece 3. For this purpose, the longitudinal edges 7 of the plates 5, 6 are welded to the inner wall of the pipe end piece 3. Between plates 5, 6 and the inner wall of the pipe end piece 3, chambers 8 are formed which are open towards the end of the connecting pipe 2.

Die stegartigen Platten 5, 6 stehen zum Austrittsende hin über den unteren Rand 6 des Rohrendstückes 3 vor und bilden die quer liegende Prallplatte 10. Vorzugsweise sind Platten 5, 6 und Prallplatte 1 0 von einem einstückigen, U-förmigen Teil gebildet.The web-like plates 5, 6 protrude toward the outlet end over the lower edge 6 of the pipe end piece 3 and form the transverse baffle plate 10. Preferably, plates 5, 6 and baffle plate 10 are formed from a one-piece, U-shaped part.

Die Prallplatte 10 und die Platten 5, 6 bilden zusammen mit dem Rohrendstück 3 seitliche, einander gegenüberliegende Austrittsöffnungen 11, 12.The baffle plate 10 and the plates 5, 6 together with the pipe end piece 3 form lateral, opposite outlet openings 11, 12.

Die über den Rand 9 vorstehenden Platten 5, 6 weisen zueinander und zur Längsmittelebene versetzte Durchlassöffnungen 13,14 auf.The plates 5, 6 protruding beyond the edge 9 have through openings 13, 14 offset with respect to one another and to the longitudinal center plane.

An den vorstehenden Enden der Platten 5, 6 sind quer zur Rohrlängsachse verlaufende, die Durchlassöffnungen 13, 14 freilassende Querstege 15, 16 befestigt. Die Querstegenden 17, 18 stehen nach beiden Seiten vorzugsweise gleich weit über die Platten 5, 6 und die gleichbreite Prallplatte 10 vor. Sie bilden damit seitliche Begrenzungen und Lenkflächen zu den Austrittsöffnungen 11, 12.At the projecting ends of the plates 5, 6 are transverse webs 15, 16 which extend transversely to the longitudinal axis of the tube and leave the through openings 13, 14 free. The crossbar ends 17, 18 protrude on both sides preferably equally far over the plates 5, 6 and the equally wide baffle plate 10. They thus form lateral boundaries and steering surfaces to the outlet openings 11, 12.

Am unteren Rand 9 des Rohrendstückes 3 sind einander gegenüberliegend Umlenkplatten 19, 20 befestigt. Ihr bis zur Höheder Prallplatte 10 vorstehender Teil ist gewölbt. Zueinander versetzte Längsränder dieser Umlenkplatten sind mit den Querstegen 15, 16 verschweisst, während die anderen im Abstand von den Querstegen 15,16 enden. Für die durch die Auslassöffnungen 13, 14 eintretenden Brennstoffteilchen und Gase bzw. Druckluft sind die Umlenkkammern 21, 22 nach abwärts und nach zueinander entgegengesetzten Seiten hin über die Austrittsöffnungen 23, 24 offen. Hierdurch kann der Brennstoff über den mittleren Ofenbereich verteilt werden. Nach oben zu stehen diese Umlenkkammern 21, 22 mit den Kammern 8 in Verbindung.Deflection plates 19, 20 are fastened opposite one another at the lower edge 9 of the pipe end piece 3. The part protruding up to the height of the baffle plate 10 is curved. Staggered longitudinal edges of these deflection plates are welded to the crosspieces 15, 16, while the others end at a distance from the crosspieces 15, 16. For the fuel particles and gases or compressed air entering through the outlet openings 13, 14, the deflection chambers 21, 22 are open downwards and on opposite sides via the outlet openings 23, 24. As a result, the fuel can be distributed over the central area of the furnace. To stand up these deflection chambers 21, 22 with the chambers 8 in connection.

Die Prallplatte 10 besitzt eine zentrische Öffnung 25, in die ein flacher Haltestift 26 einer Einlegeplatte 27 oder eines U-förmigen Einlegeteiles 28 einsetzbar ist. Die Platten bzw. U-förmigen Einlegeteile 27, 28 passen zwischen den Platten 5, 6 und stehen mit ihren Enden über die Prallplatte 10 vor. Durch Einsetzen ein oder mehrerer plattenförmiger Einlegeteile 27 können die Austrittsöffnungen 11, 12, 13 und 14 in ihrer Höhe verändert werden. Hierdurch ist eine Anpassung der Brennstoffverteilung an unterschiedliche Ofenabmessungen bzw. Brandbedingungen möglich. Durch das U-förmige Einlegeteil 28 kann mittels derseitlich hochgezogenen Ränder 29,30 der freie Durchlassquerschnitt der Durchlassöffnungen 13, 14 verändert werden. U-förmige und plattenförmige Einlegeteile können auch kombiniert werden.The baffle plate 10 has a central opening 25 into which a flat retaining pin 26 of an insert plate 27 or a U-shaped insert 28 can be inserted. The plates or U-shaped inserts 27, 28 fit between the plates 5, 6 and have their ends above the baffle plate te 10 before. By inserting one or more plate-shaped inserts 27, the height of the outlet openings 11, 12, 13 and 14 can be changed. This makes it possible to adapt the fuel distribution to different furnace dimensions or fire conditions. The free passage cross section of the passage openings 13, 14 can be changed by the U-shaped insert 28 by means of the raised edges 29, 30. U-shaped and plate-shaped inserts can also be combined.

Zündglühkopf und Einlegeteile bestehen aus hochhitzebeständigem Metall, insbesondere Stahl.Glow plug and inserts are made of highly heat-resistant metal, especially steel.
