Description

Schieberanordnung für Tunnelöfen Die Erfindung betrifft eine Schieberanordnung im Tunnelofenbrennkanal.Slide arrangement for tunnel kilns The invention relates to a slide arrangement in the tunnel kiln tunnel.

Der Zweck der Erfindung ist, die Verbrennungsluft, sowie die Abgase ohne zusätzliche Umgehungskanäle im Ofenmauerwerk von einer Tunnelofenzelle direkt zur benachbarten Tunnelofenzelle zu leiten und den Bau, sowie die Funktion des Tunnelofens zu vereinfachen.The purpose of the invention is the combustion air, as well as the exhaust gases without additional bypass channels in the kiln masonry from a tunnel kiln cell directly to lead to the neighboring tunnel kiln cell and the construction, as well as the function of the tunnel kiln to simplify.

Es sind Tunnelöfen bekannt, die durch Schieber in mehrere Kammern aufgeteilt werden. Diese Schieber versperren aber den gesamten Brennkanalquerschnitt.There are tunnel ovens known that slide into several chambers be divided. However, these slides block the entire cross-section of the combustion duct.

Die Gasführung in den einzelnen Kammern geschieht in der Art, daß die durch die seitlich im Ofenmauerwerk angeordneten Brenner beheizbaren Abgase unter das Brennkanalgewölbe und von da aus vertikal nach unten durch Löcher und Kanäle im Tunnelofenwagenbelag fließen und durch das Seitenmauerwerk abgezogen werden. Die Gase werden der nächsten Einfahrt nähergelegenen Kammer auf die gleiche Weise wieder zugeführt. WP Nr. 46235, So c. Weiterhin wurden "die deutschen Patentschriften DB Nr. 1 17? 541, 80 c 5 und DB Nr. 1 204 572, 8o c 1701 eingesehen.The gas flow in the individual chambers is done in such a way that the exhaust gases, which can be heated by the burner arranged on the side of the furnace masonry, flow under the combustion duct vault and from there vertically down through holes and channels in the tunnel kiln car covering and are drawn off through the side masonry. The gases are fed back in the same way to the next chamber closer to the entrance. WP No. 46235, So c. Furthermore, "the German patents DB No. 1 17-541, 80 c 5 and DB No. 1 204 572, 80 c 1701 were inspected.

Diese Schieberanordnung in den Tunnelöfen hat jedoch den Nachteil, daß für die Abgasführung im Tunnelofenmauerwerk ein Kanalsystem geschaffen werden muB, das die Baukosten erhöht. Weiterhin wird durch Undichtigkeiten, welche an den Übergängen zwischen Tunnelofeneohlzügen und dem Hau- erwerk vorhanden sind, die Wirkungaweiae beeinflußt, in- dem die Abgase nicht nur durch die W"eneoUe, sondern auch direkt wtu der Bsc abgwsog= werden. Der Erfindung liegt die Aufgabe zugrunde, eine Schieber- anordnung zu entwickeln, welche die Iräagszirkulation -der Gase unterbindet, .aber trotzdem -einen Längszug im Tumel- ofen gewährleistet. Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß bei geschlossener Tugaelofeneinfahrt und stillstehendem Tm- nelofenwagen die Sctiebsr vom Anfang .der Vorwärmzane bis in die Feuerzone, -mit der höchsten Tempasatur, -so in Aen Tunaelofenbrenukanal regen, daß zw3.schen den Schieberuaa- terkanten und den TunnelofenwaKimsohlen Schlitz«fna frei bleiben, während der obere Teil .den 13:::: re@al;quer- schnitt dicht abschließt und von .der Feuerze.mtt der höchsten Temparatur durch die Kühlzone bis zum T.uunel- ofenaustritt so angeordnet sind.,.daß die Schieberunter- kanten auf der Tuanelofenwagensohle -dicht aufsitzen und .den oberen Teildes Srenakanalquerschnittes am Gewölbe offen lassen. Damit ist die Frischluft auf ihrem Wege von der Tunnelofenausfahrt über die Feuerzone zum Abzwg1 an der Tunnelofeneinfahrt bei geschlossenen Schieben und stillstehenden Tunnelofenwagen gezwungen, von der W MMZI-Minr t bis zur Feuerzone, also in der Kühlzone, am Gewb`1be eat- lanzustreicheu, wobei sie die Ware abklt .und sich dabei selbst erwärmt. Von der Feuerzone aus bin =r Ofeneinfahrt streichen die Abgase auf der @u@ei@a@gen- sohle entlang, kühlen sich dabei ab und wärmen .die im brennende Keremik vor,, Die Erfindung soll nachstehend an einem Ausführuzgebei- spiel näher erläutert -werden. Die zugehörige Zeicbawig zeigt einmgs."tt -des Tunaelofeae, Während des @3rermens, bei stillstehendenen.wm'@nm@a 21 bis 29 und gesahloeeannt Schieber lo an 'T-numlatt- eiatahrt wird 3W, zur Verbrenn der . immereIne bestehend aus den 'Zellia 14 bis 16, durch da :,iM Abzugskanals 2o vom Tumamloßenwa@ sag lisbr 1 her, angeführt. Folgender Weg durch den Tunnelofenkanal wird durch die Schieberanordnung der angesausten Frischluft vorgeschrieben: Der am Gewölbe des Tunnelofens offene Schieber 1 gestattet den Eintritt am Tnnnelofenwagenaustritt der Frischluft in die Kühlzone, bestehend aus den Zellen 11 bis 13 mit den Schiebern 2 und 3, wo sich die Frischluft er -wärmt und durch Wärmeaustausch die gebrannte Ware auf dem auszufahrenden Tunnelofenwagen 21 und 23 abkühlt.However, this slide arrangement in the tunnel kiln has the disadvantage that a duct system has to be created for the exhaust gas duct in the tunnel kiln masonry, which increases the construction costs. Furthermore, leaks that occur at the transitions between tunnel kiln sections and the building works are present, the effect aweiae influences, in- which the exhaust gases not only through the W "eneoUe, but also directly wtu of the Bsc are deducted. The invention is based on the object of a slide valve to develop an arrangement that would Prevents gases, but nevertheless -a longitudinal pull in the T by el- oven guaranteed. According to the invention the object is achieved in that at closed Tugaelofen entrance and stationary Tm- nelofenwagen the Sctiebsr from the beginning of the preheating zone to in the fire zone, -with the highest tempasatur, -so in Aen Tunaelofenbrenu Canal rain that between the Schieberuaa- edges and the tunnel ovenwa Kim soles slot «fna remain free, while the upper part of the 13 :::: re @ al; transverse- cut tightly and from the fire highest temperature through the cooling zone up to T.uunel- the oven outlet are arranged in such a way that the edges on the sole of the Tuanel oven -tight sit and the upper part of the srena canal cross-section on the vault leave open. So the fresh air is on its way from the tunnel kiln exit over the fire zone to Abzwg1 at the tunnel kiln entrance with the slides closed and stationary tunnel kiln car forced to be used by the W MMZI-Minr t to the fire zone, i.e. in the cooling zone, at Gewb`1be eat- lanzustreicheu, with the Goods abklt. And warms itself up in the process. From the fire zone bin = r Oven entrance paint the exhaust gases on the @ u @ ei @ a @ gen- along the sole , cool down and warm burning keremik in front of, The invention is to be based on an exemplary embodiment below. game will be explained in more detail. The associated Zeicba wi g shows some "tt -des Tunaelofeae, During @ 3rermens, when en.wm '@ nm @ a 21 to 29 and gesahloeeannt slide l o an 'T- numlat t- eiatahrt is 3W, to the Burn. always consisting of the 'Zellia 14 to 16, through da:, iM Discharge duct 2o from Tumamloßenwa @ sag lisbr 1 listed . The following route through the tunnel kiln channel is prescribed by the slide arrangement of the fresh air drawn in: Slide 1, which is open on the vault of the tunnel kiln, allows fresh air to enter the cooling zone at the tunnel kiln car outlet, consisting of cells 11 to 13 with sliders 2 and 3, where the Fresh air warms up and the fired goods on the tunnel kiln cars 21 and 23 to be moved out are cooled by heat exchange.

Die erwärmte Luft aus der Zelle 13 gelangt dann durch die Öffnung zwischen dem Schieber 4 und dem Ofengewölbe zur Feuerzone, bestehend aus den Zellen 14 bis 16, welche durch die Schieber 5 und 6 getrennt sind. Die hierin durch die Verbrennung entstehenden Gase werden von der Zelle 15 in Richtung Tunnelofeneinfahrt durch die zwischen der Unterkante der Schieber 6 bis 9 und der Sohle der Tunnelofenwagen 27 bis 29 die in der Feuerzone bzw. Vorwärmzone, dargestellt durch die Zellen 16 bis 19, stehen, in den Abzuzskanal 2o ins Freie ab.meleitet.The heated air from the cell 13 then passes through the opening between the slide 4 and the furnace vault to the fire zone, consisting of the cells 14 to 16, which are separated by the slider 5 and 6. The herein by the Combustion resulting gases are from the cell 15 in the direction of the tunnel kiln entrance through the between the lower edge of the slide 6 to 9 and the bottom of the tunnel kiln car 27 to 29 those in the fire zone or preheating zone, represented by cells 16 to 19, are in the exhaust duct 2o into the open.

Dabei bleibt Schieber 1o am Tunneloienwageneintritt geschlossen. Durch die Schieberanordnung wird der Wirkungsgrad wesentlich verbessert, die Undichtigkeiten auf ein Mindestmaß verringerte die Baukosten und die Instandhaltungskosten des Tunnelofens herabgesetzt, sowie die Lebensdauer verlängert.Slide 1o at the tunnel car entrance remains closed. By the slide assembly, the efficiency is significantly improved, the leaks minimized the construction and maintenance costs of the tunnel kiln decreased, as well as extended the service life.
