Abstract

A device (10) for removing ashes from a tunnel kiln car (2) loaded with burned bricks consists of a large number of nozzles (11) and suction channels (13) arranged directly in the tunnel kiln (1), by means of which the ash lying on the tunnel kiln car (2) and on the charge (4) is blown and sucked off. In this manner, the ash arising in coal firing is easy to remove, without the bricks dirtied with ash leaving the tunnel kiln and dirtying being caused in the brickworks (Fig. 1). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Vorrichtung und ein Verfahren zum Entaschen eines mit gebrannten Formlingen bestückten Tunnelofenwagens.The invention relates to a device and a method for ash removal from a tunnel kiln car equipped with fired moldings.

Bei Tunnelöfen, die mit Kohlefeuerungen ausgerüstet sind, ist die Beseitigung der unvermeidbar anfallenden Asche mit großen Problemen verbunden. Bisher sind dazu sogenannte Entaschungskammern vorgesehen, in die der Tunnelofenwagen nach Verlassen des Tunnelofens gefahren wird. In diesen Kammern wird die auf dem Tunnelofen und dem Besatz lagernde Asche durch eine große Luftmenge losgerissen und abgesaugt. Abgesehen von dem für die Entaschungskammern erforderlichen zusätzlichen großen Bauaufwand ist es bei dieser Art der Entaschung unumgänglich, daß die Asche im gesamten Ziegelwerk verteilt wird. Oftmals stehen nämlich die Türen des Ofengebäudes sowie der Entaschungskammern und des Tunnelofens über längere Zeit offen, zumindest aber müssen diese zum Ein- und Ausfahren der Tunnelofenwagen geöffnet werden, so daß große Luftbewegungen auch in der Ofenhalle und ein dadurch bedingtes Austreten der Asche nicht zu verhindern sind.In tunnel kilns that are equipped with coal firing, the removal of the inevitable ashes is associated with major problems. So far, so-called ash removal chambers have been provided, into which the tunnel kiln car is driven after leaving the tunnel kiln. In these chambers, the ash stored on the tunnel kiln and the trimmings is torn away and extracted by a large amount of air. Apart from the additional large construction effort required for the ash removal chambers, it is inevitable with this type of ash removal that the ash is distributed throughout the brick plant. Often the doors of the kiln building as well as the ash removal chambers and the tunnel kiln are open for a long time, but at least they have to be opened to move the tunnel kiln car in and out so that large air movements in the kiln hall and the resulting escape of the ash cannot be prevented are.

Es ist daher Aufgabe der Erfindung, eine Vorrichtung sowie ein Verfahren zum Entaschen eines mit gebrannten Formlingen bestückten Tunnelofenwagens zu schaffen, durch die vermieden wird, daß sich Asche im Ziegelwerk verteilen kann. Außerdem soll der Bauaufwand, um dies zu bewerkstelligen, sehr gering gehalten werden, so daß ein auch mit einer Kohlefeuerung ausgerüstetes Ziegelwerk sauber zu halten ist und durch Asche bedingte Betriebsstörungen vermieden sind.It is therefore an object of the invention to provide a device and a method for ash removal from a tunnel kiln car equipped with fired moldings, by means of which ash is prevented from being distributed in the brickworks. In addition, the construction effort to accomplish this should be kept very low, so that a brick plant equipped with coal firing must be kept clean and operating problems caused by ash are avoided.

Gemäß der Erfindung wird dies dadurch erreicht, daß unmittelbar im Tunnelofen,vorzugsweise vor dem Ofenausgang,in der Tunnelofendecke und/oder in den Seitenwänden eine Mehrzahl von Düsen und aus dem Tunnelofen herausführende Absaugkanäle angeordnet sind, mittels denen die auf dem Tunnelofenwagen und dem Besatz lagernde Asche abblasbar und absaugbar ist.According to the invention, this is achieved in that a plurality of nozzles and suction channels leading out of the tunnel furnace are arranged directly in the tunnel furnace, preferably in front of the furnace exit, in the tunnel furnace ceiling and / or in the side walls, by means of which the bearings on the tunnel furnace car and the trimmings Ash can be blown off and extracted.

Zweckmäßig ist es hierbei, einer Düse jeweils einen etwa gegenüberliegend angeordneten Absaugkanal zuzuordnen und die Düsen und Absaugkanäle jeweils wechselweise in Reihen anzuordnen, so daß ein ständiger Wechsel zwischen Anblasen und Absaugen gegeben ist.It is expedient here to assign a suction duct arranged approximately opposite each other and to arrange the nozzles and suction ducts alternately in rows, so that there is a constant change between blowing and suctioning.

Sehr vorteilhaft ist es des weiteren, die mittels der Düsen in den Tunnelofen geleiteten Luftströme impulsweise in diesen einzublasen. Dadurch wird eine besonders intensive Reinigung erreicht.It is also very advantageous to blow the air streams directed into the tunnel furnace by means of the nozzles in pulses. A particularly intensive cleaning is thereby achieved.

Ferner ist es angebracht, die Düsen als Düsenrohre mit in unterschiedlichen Höhenlagen angeordneten Düsenöffnungen auszubilden und die Absaugkanäle mit in unterschiedlichen Höhenlagen angeordneten, vorzugsweise schlitzartigen Absaugöffnungen zu versehen.It is also appropriate to design the nozzles as nozzle tubes with nozzle openings arranged at different heights and to provide the suction channels with preferably slot-like suction openings arranged at different heights.

Bei einem mit Längsschlitzen zwischen den einzelnen Paketen des Besatzes betriebenen Tunnelofen ist es des weiteren zweckmäßig, die Düsen und die Absaugkanäle derart anzuordnen, daß diese ganz oder teilweise in die Längschlitze eingreifen. Bei einem periodisch betriebenen Tunnelofen ist es ferner angebracht, die Düsen und Absaugkanäle aus- und einfahrbar anzuordnen.In the case of a tunnel furnace operated with longitudinal slots between the individual packages of the trimmings, it is furthermore expedient to arrange the nozzles and the suction channels in such a way that they engage wholly or partially in the longitudinal slots. In the case of a periodically operated tunnel kiln, it is also appropriate to arrange the nozzles and suction channels so that they can be extended and retracted.

Außerdem sollten, um restliche Asche zu entfernen, am Ausgang des Tunnelofens vorzugsweise bis nahe an die Ofenwagensohle ragende Absaugschächte angeordnet werden, und zwar sollten diese, um nicht durch einzelne Formlinge beschädigt zu werden, beweglich sein.In addition, in order to remove residual ash, suction ducts projecting close to the bottom of the kiln car should preferably be arranged at the exit of the tunnel kiln, and these should be movable so that they are not damaged by individual moldings.

Das erfindungsgemäße Verfahren zum Entaschen eines mit gebrannten Formlingen bestückten Tunnelofenwagens ist dadurch gekennzeichnet, daß mit Hilfe von im Tunnelofen vorzugsweise vor dem Ausgang angeordneter Düsen der Tunnelofenwagen und der Besatz von einem Luftstrom angeblasen wird, der mittels der Düsen etwa gegenüberliegend angebrachter Absaugkanäle abgesaugt wird.The method according to the invention for ash removal from a tunnel kiln car equipped with fired moldings is characterized in that the tunnel kiln car and the trimmings are blown by means of nozzles arranged preferably in front of the exit of the tunnel kiln car and an air flow is blown off, which is suctioned off by means of the nozzles arranged approximately opposite one another.

Hierbei sollten die Luftströme zwischen zwei benachbarten einander zugeordneten Düsen und Absaugkanälen jeweils entgegengesetzt gerichtet sein, auch können die Luftströme impulsweise durch die Düsen eingeblasen werden.In this case, the air flows between two adjacent nozzles and suction channels which are assigned to one another should be directed in opposite directions, and the air flows can also be blown in through the nozzles in pulses.

Durch die gemäß der Erfindung ausgebildete Vorrichtung zum Entaschen eines mit gebrannten Formlingen bestückten Tunnelofenwagens sowie das erfindungsgemäße Verfahren wird es mit einfachen Mitteln ermöglicht, die bei einer Kohlefeuerung unvermeidbar anfallende Asche abzuführen, ohne daß durch diese das Ziegelwerk und die Umgebung verunreinigt werden. Werden nämlich unmittelbar im Tunnelofen Düsen und Absaugkanäle vorgesehen, so ist es möglich, die Asche, bevor der Tunnelofenwagen den Tunnelofen verläßt, abzublasen und abzusaugen, so daß keine Asche nach außen gelangt. Die Tunnelofenwagen und der Besatz sind auf diese Weise hinreichend von der anhaftenden Asche zu befreien, die Verschmutzungsgefahr ist somit, da mit Asche bestückte Tunnelofenwagen nicht außerhalb des Tunnelofens bewegt werden, außerst gering. Durch Asche bedingte Betriebsstörungen werden im Ziegelwerk auf diese Weise zuverlässig verhindert, außerdem wird dieses saubergehalten.The device designed according to the invention for ash removal from a tunnel kiln car equipped with fired moldings and the method according to the invention make it possible with simple means to remove the ash which is inevitably obtained in coal firing, without the brickwork and the environment being contaminated thereby. If nozzles and suction channels are provided directly in the tunnel furnace, it is possible to blow off and vacuum the ashes before the tunnel furnace car leaves the tunnel furnace, so that no ashes can escape to the outside. The tunnels In this way, oven wagons and the trimmings can be adequately freed from the adhering ash, the risk of contamination is therefore extremely low, since tunnel oven wagons equipped with ash are not moved outside the tunnel oven. In this way, operational disruptions caused by ash are reliably prevented in the brickworks, and this is also kept clean.

In der Zeichnung ist die gemäß der Erfindung ausgebildete Vorrichtung zum Entaschen eines mit gebrannten Formlingen bestückten Tunnelofenwagens schematisch dargestellt und nachfolgend im einzelnen erläutert. Hierbei zeigen:

In the drawing, the device designed according to the invention for ash removal from a tunnel kiln car equipped with fired moldings is shown schematically and explained in detail below. Here show:
  • Fig. 1 shows a tunnel kiln section with nozzles and suction channels arranged in this for removing the accumulated ash in side view
  • Fig. 2 shows the tunnel kiln section of FIG. 1 in plan view.

Die in einem Tunnelbereich eines Tunnelofens 1 vorgesehene mit 1o bezeichnete Vorrichtung zur Beseitigung der durch den Betrieb des Tunnelofens mittels einer Kohlefeuerung anfallenden Asche, die sich auf den Tunnelofenwagen 3 sowie dem auf diesen ruhenden Besatz 4 abgelagert hat, besteht aus Düsen 11 und Absaugkanälen 13, mittels denen Luftströme in den Tunnelofen 1 geblasen und abgesaugt werden. Die Düsen 11 sind hierbei aus in der Decke 2 des Tunnelofens 1 angeordneten Düsenrohren gebildet, in die in unterschiedlichen Höhenlagen Düsenöffnungen 12 eingearbeitet sind. Die Absaugkanäle 13 sind mit einer Vielzahl von Absaugschlitzen 14 ausgestattet, durch die die Asche in die Kanäle 13, die aus dem Tunnelofen 1 herausgeführt sind, in diese eintritt.The device provided in a tunnel area of a tunnel kiln 1, designated 1o, for removing the ashes resulting from the operation of the tunnel kiln by means of coal firing, which has deposited on the tunnel kiln car 3 and the trimmings 4 resting thereon, consists of nozzles 11 and suction channels 13, by means of which air flows are blown into the tunnel kiln 1 and extracted. The nozzles 11 are formed from nozzle tubes arranged in the ceiling 2 of the tunnel furnace 1, into which nozzle openings 12 are incorporated at different altitudes. The suction channels 13 are equipped with a large number of suction slots 14, through which the ashes enter the channels 13 which are led out of the tunnel furnace 1.

Der Besatz 4 der Tunnelofenwagen 2 ist in einzelnen Paketen 5, 5' und 5" unterteilt, so daß Längsschlitze 6 und 6' gebildet sind. Die Düsen 11 sowie die Absaugkanäle 13, die wechselweise in Reihe angeordnet sind, können somit auch in die Schlitze 6 und 6' des Besatzes 4 eingreifen. Auf diese Weise läßt sich eine besonders intensive Reinigung, da die von dem Luftstrom zurückzulegenden Wege kurz sind und dieser mit hoher kinetischer Energie auf das zu reinigende Teil auftrifft, erzielen.The lining 4 of the tunnel kiln cars 2 is divided into individual packages 5, 5 'and 5 ", so that longitudinal slots 6 and 6' are formed. The nozzles 11 and the suction channels 13, which are alternately arranged in a row, can thus also enter the slots 6 and 6 'of the trimming 4. In this way, particularly intensive cleaning can be achieved since the paths to be covered by the air flow are short and this impinges on the part to be cleaned with high kinetic energy.

Durch die zwischen einer Düse 11 und einem Absaugkanal 13 jeweils entgegengesetzt zueinander gerichteten Luftströme, die zweckmäßigerweise auch impulsweise in den Tunnelofen 1 geleitet werden können, wird die an den Tunnelofenwagen 2 sowie dem Besatz 4'haftende Asche losgerissen und von den Absaugkanälen 13 aufgenommen. Die Formlinge verlassen somit, zumal am Ofenausgang weitere Absaugschächte 15 allseitig beweglich angeordnet sind, um eventuell noch vorhandene Aschereste aufzunehmen und von hinuntergefallenen Formlingen nicht beschädigt zu werden, gesäubert den Tunnelofen 1, Verunreinigungen des Ziegelwerkes sind demnach zuverlässig vermieden.The ashes adhering to the tunnel kiln car 2 and the trimmings 4 ′ are torn away and taken up by the suction channels 13 due to the air flows which are directed in opposite directions to one another between a nozzle 11 and a suction channel 13 and which can expediently also be passed in pulses. The moldings thus leave, especially since further suction shafts 15 are arranged to be movable on all sides at the furnace exit, in order to take up any ash residues that may still be present and not to be damaged by fallen moldings, cleaned the tunnel furnace 1, so contamination of the brickworks is reliably avoided.
