Abstract

An installation for charging melting furnaces is proposed, which consists of a combination of a horizontal conveyor (2) designed as a moving floor and a steep conveyor (3). The product to be conveyed (14) is extracted from a storage container (5) on the moving floor and displaced to the steep conveyor . The steep conveyor (3) has carriers (12) which transport the product to be melted (14) upwards on a sliding floor (7) to the emptying station (8). By means of this charging system (horizontal conveyor-steep conveyor), it is possible for the first time in installations of this type to carry out fully automatic furnace operation. The charging system controls and monitors itself by means of installed sensors and is integrated into the furnace process. The sensors control and monitor the levels in the furnace, in the steep conveyor and in the horizontal conveyor. As a result of this, optimum operation of the furnace installation is achieved. Errors by personnel no longer exist as no personnel are necessary. Moreover, there is also as a result optimum energy use and thus a minimum of emissions. <IMAGE>

Description

Die Erfindung betrifft eine Beschickungsvorrichtung für Schmelzöfen, bei der das Fördergut einem Förderelement zugeführt wird, das das Fördergut zu der Beschickungsstelle des Ofens transportiert und in den Ofen entleert.The invention relates to a charging device for melting furnaces, in which the material to be conveyed is fed to a conveying element which transports the material to be conveyed to the charging point of the furnace and empties it into the furnace.

Als Beschickungsvorrichtungen für Schmelzöfen sind senkrechte bzw. leicht geneigte Hebekippgeräte bekannt. Bei diesen bekannten Vorrichtungen wird das Schmelzgut entweder in fest eingebauten Kübeln oder in in die Vorrichtung einschiebbare Wagen oder Behälter nach oben zur Beschickungsstelle transportiert und in einer Kippbewegung von ungefähr 135o in den Ofen entleert. Diese bekannten Vorrichtungen haben den Nachteil, daß nur maßlich festgelegte Behälter oder Wagengrößen verwendet werden können, d.h. ein direktes Entleeren verschieden großer Behälter ist nicht möglich, so daß zwischengeschaltete Umladestationen notwendig sind, die mit einem erhöhten Personalbedarf verbunden sind. Außerdem wird das Schmelzgut zum größten Teil insgesamt in den Ofen entleert, wodurch eine große momentane Ofenbelastung entsteht, die zu Schäden führen kann.Vertical or slightly inclined lifting and tipping devices are known as charging devices for melting furnaces. In these known devices the material to be melted is either transported in or built-in tubs insertable into the device cart or container according to the above feed point and o emptied into a tilting movement of about 135 in the furnace. These known devices have the disadvantage that only dimensionally defined containers or wagon sizes can be used, ie direct emptying of containers of different sizes is not possible, so that intermediate transfer stations are necessary, which are associated with an increased need for personnel. In addition, most of the melting material is emptied into the furnace as a whole, which creates a large instantaneous furnace load, which can lead to damage.

Weiterhin sind als Beschickungsvorrichtungen Förderbänder bekannt, die das Schmelzgut auf einer Schräge bis zur Entleerungsstelle transportieren. Derartige Förderbänder benötigen aber zum Überwinden der vorgegebenen Beschickungshöhe eine große Bahnlänge, so daß sie häufig aus Platzgründen nicht eingesetzt werden.Conveyor belts are also known as feeding devices, which transport the melting material on a slope to the emptying point. However, such conveyor belts require a large length of track to overcome the specified loading height, so that they are often not used for reasons of space.

Darüber hinaus gibt es Schwingförderrinnen und hydraulisch betätigte Schieber-Rinneneinrichtungen. Derartige Geräte können aber nur in Kombination mit einem Hebekippgerät eingesetzt werden, das schon oben beschrieben ist, da eine relativ große Förderhöhe zu überwinden ist. Zudem sind Schwingförderrinnen aufgrund der hohen Lärmemission nur mit aufwendigen Lärmschutzvorrichtungen betreibbar.There are also vibratory feeders and hydraulically operated slide channel devices. However, such devices can only be used in combination with a lifting and tipping device, which has already been described above, since a relatively large head has to be overcome. In addition, due to the high level of noise emission, vibratory conveyor troughs can only be operated with complex noise protection devices.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Beschickungsvorrichtung für Schmelzöfen zu schaffen, die für unterschiedliche Größen des Schmelzgutes eine schnelle und geräuscharme Beschickung zu dem Schmelzofen ermöglicht, wobei die Vorrichtung kostengünstig in der Anschaffung und im Betrieb und ihr Raumbedarf gering sein soll.Based on this prior art, the invention has for its object to provide a charging device for melting furnaces, which enables rapid and low-noise loading to the melting furnace for different sizes of the melting material, the device being inexpensive to buy and operate and requiring little space should be.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Hauptanspruchs gelöst.This object is achieved by the characterizing features of the main claim.

Dadurch, daß die Beschickungsvorrichtung aus einer Kombination eines als Wanderboden ausgebildeten Waagerechtförderers und eines Steilförderers besteht, können beliebige Güter in verschiedensten Formen bis zu bestimmten Abmessungen und Gewichten schnell und geräuscharm transportiert werden. In den Vorratsbehälter des Wanderbodens können beliebig große Behältnisse von Hand oder maschinell entleert werden. Das Austragen des Schmelz- oder Fördergutes ist unabhängig von dem Füllzustand des Behälters. Die Vorrichtung bedarf keiner personellen Bedienung. Weiterhin kann die Austraggeschwindigkeit variiert werden, so daß eine Automatitationsmöglichkeit gegeben ist. Die Abwurfhöhe an der Entleerungs- oder Beschickungsstelle wird bei der erfindungsgemäßen Vorrichtung im Gegensatz zu Förderbänder- oder Hebekippgeräten wesentlich niedriger gehalten. Dies trägt zur Schonung des Ofens bei und verringert den Platzbedarf in der Höhe.Because the loading device consists of a combination of a horizontal conveyor designed as a moving floor and a steep conveyor, any goods in a wide variety of shapes up to certain dimensions and weights can be transported quickly and quietly. Containers of any size can be emptied by hand or by machine into the storage container of the moving floor. The discharge of the melting or conveyed material is independent of the filling status of the container. The device does not require any personal operation. Furthermore, the discharge speed can be varied so that automation is possible. The discharge height at the emptying or loading point is kept significantly lower in the device according to the invention in contrast to conveyor belts or lifting and tipping devices. This helps to protect the oven and reduces the space required at height.

Durch die in den Unteransprüchen angegebenen Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen möglich. Durch die Taschenform erfolgt eine Separierung des Förder- oder Schmelzgutes, wodurch eine zu große Ofenbelastung im Einfüllbereich vermieden wird, da immer nur der Inhalt einer Tasche bzw. eines Mitnehmers in den Ofenraum fällt. Bei Einschalten der Anlage steht sofort ohne Anlaufzeit, wie bei Hebekippgeräten, das Förder- oder Schmelzgut an der Entleerungsstelle zur Verfügung, da alle Taschen oder Mitnehmer gefüllt sind und sich eine nach der anderen entleert.Advantageous further developments and improvements are possible through the measures specified in the subclaims. The shape of the bag separates the material to be conveyed or melted, thereby avoiding excessive furnace loads in the filling area, since only the contents of a bag or a carrier fall into the furnace chamber. When the system is switched on, the material to be conveyed or melt is immediately available at the emptying point without a start-up time, as is the case with lifting and tipping devices, since all pockets or carriers are filled and emptied one after the other.

An embodiment of the invention is shown in the drawing and is explained in more detail in the following description.
Show it:
Fig. 1
a top view of a furnace with a loading device and
Fig. 2
a side view, especially on the furnace with steep conveyor.

In Fig. 1 ist mit 1 der Schmelzofen bezeichnet. In einem derartigen Ofen wird Material eingeschmolzen, das Einzelgewichte von unter 1 kg bis 38 kg und Abmessungen von 30 x 40 x 10 mm bis 800 x 600 x 600 mm aufweist. In der Stunde müssen ca. 1000 bis 7000 kg, eventuell auch mehr, des Schmelzgutes in den Ofen 1 gefüllt werden. Die Beschickung wird über den als Wanderboden ausgebildeten Waagerechtförderer 2 und den Steilförderer 3 durchgeführt. Der Wanderboden besteht aus einer Mehrzahl von nebeneinanderliegenden Profilleisten 4 mit einem darunterliegenden, nicht dargestellten hydraulikbetriebenen Verschiebesystem. Für die Verschiebebewegung des Wanderbodens, auch Walking-Floor genannt, verschiebt sich ein Teil der Profilleisten als Gruppe um einen bestimmten Weg, wobei die Ladung stehenbleibt. Danach verschiebt sich eine weitere Gruppe von Profilleisten um den gleichen Weg, wobei ebenfalls die Ladung stehenbleibt. Anschließend verschiebt sich eine dritte Gruppe von Profilleisten um den gleichen Weg und die Ladung bleibt stehen. In der nächsten Phase verschieben sich die drei Gruppen von Profilleisten gleichzeitig nach vorne, wodurch die Ladung sich bewegt. Ein derartiger Zyklus wird im folgenden wiederholt, wobei jeweils das hydraulikbetriebene Verschiebesystem die Steuerung der Profilleisten vornimmt. Auf den Profilleisten befindet sich ein feststehender, nach oben offener Vorratsbehälter 5, dessen Seitenwände alle oder auch einzeln geneigt sein können. Beim Verschieben der Profilleisten wird das Schmelzgut in Längsrichtung aus einer Öffnung im Vorratsbehälter heraustransportiert und in Richtung Steilförderer 3 bewegt.In Fig. 1, 1 is the melting furnace. In such a furnace material is melted, which has individual weights of less than 1 kg to 38 kg and dimensions of 30 x 40 x 10 mm to 800 x 600 x 600 mm. Approximately 1000 to 7000 kg, possibly even more, of the melting material must be filled into the furnace 1 per hour. The loading is carried out via the horizontal conveyor 2 designed as a moving floor and the steep conveyor 3. The moving floor consists of a plurality of side-by-side profile strips 4 with an underlying hydraulic-operated displacement system, not shown. For the sliding movement of the moving floor, also known as the walking floor, part of the profile strips moves as a group by a certain path, whereby the load stops. Then another group of profile strips moves the same way, whereby the load also stops. Then a third group of profile strips moves the same way and the load stops. In the next phase, the three groups of profile strips move forward simultaneously, causing the load to move. Such a cycle is repeated below, with the hydraulically operated displacement system controlling the profile strips. There is a fixed, upwardly open storage container 5 on the profile strips, the side walls of which can be inclined all or individually. When the profile strips are moved, the melt material is transported in the longitudinal direction out of an opening in the storage container and moved in the direction of the steep conveyor 3.

Der Steilförderer 3 besteht aus einer Stahl-Rahmenkonstruktion, in dessen unterem Bereich in einer Seitenwand eine Einfüllöffnung 6 vorgesehen ist. In diese Einfüllöffnung 6 greifen die Profilleisten 4 des Waagerechtförderers 2 ein. In der Rahmenkonstruktion ist ein Gleitboden 7 angeordnet, der sich von der Einfüllöffnung 6 bis zur Entleerungsstelle 8 erstreckt. Im oberen Bereich der Stahl-Rahmenkonstruktion befindet sich eine Antriebswelle 9 mit zwei Kettenrädern und einem vorzugsweise hydraulischen Antrieb. Über die Kettenräder und evtl. weitere, in der Rahmenkonstruktion vorgesehene Kettenräder 10 werden zwei Rollenketten 11 geführt, an denen Mitnehmer 12 angebracht sind. Die Mitnehmer 12 bilden Taschen für das Schmelzgut, das von den in die Einfüllöffnung 6 eingreifenden Profilleisten 4 des Wanderbodens 2 direkt in die als Taschen ausgebildeten Mitnehmer 12 fällt. Durch das Drehen der Antriebswelle 9 setzen sich die Ketten 11 mit den daran angebrachten Mitnehmern 12 in Bewegung, wodurch das Schmelzgut auf dem Gleitboden 7 nach oben transportiert wird. An der Entleerungsstelle 8, die durch das Ende des Gleitbodens 7 gebildet wird, ist eine Mitnehmeranhebevorrichtung vorgesehen, durch die jeder Mitnehmer angehoben wird, damit er sich vollständig entleeren kann. An der Entleerungsstelle 8 fällt das Schmelzgut aus dem Steilförderer in den
   Ofen 1. Das Schmelzgut 14 wird mittels Gabelstapler 15 oder mittels eines Kranes diskontinuierlich in den Vorratsbehälter 5 des Waagerechtförderers 2 entleert. Das Austragen des Schmelzgutes 14 aus dem Vorratsbehälter 5 ist unabhängig von seinem Füllzustand, wobei die Austraggeschwindigkeit an die Gegebenheiten angepaßt werden kann. Die Transportkapazität des Waagerechtförderers 2, der auch geneigt angeordnet sein kann, beträgt mehr als 10 t/h. Das Schmelzgut 14 fällt in die als Taschen ausgebildeten Mitnehmer 12 und wird kontinuierlich oder diskontinuierlich nach oben transportiert. Dabei kann die Transportgeschwindigkeit ebenfalls an die Gegebenheiten angepaßt werden. Da immer nur kleine Mengen von Schmelzgut 14 in den Mitnehmertaschen 12 transportiert werden, fallen an der Entleerungsstelle 8 auch nur kleine Mengen in den
   Ofen 1, so daß der Ofen im Beschickungsbereich nicht zu sehr belastet wird.The steep conveyor 3 consists of a steel frame construction, in the lower area of which a filling opening 6 is provided in a side wall. The profile strips 4 of the horizontal conveyor 2 engage in this filling opening 6. A sliding floor 7 is arranged in the frame construction and extends from the filling opening 6 to the emptying point 8. In the upper area of the steel frame construction there is a drive shaft 9 with two sprockets and a preferably hydraulic drive. Two roller chains 11, to which drivers 12 are attached, are guided over the chain wheels and possibly other chain wheels 10 provided in the frame construction. The drivers 12 form pockets for the melted material, which falls directly from the profile strips 4 of the moving floor 2, which engage in the filling opening 6, into the carriers 12, which are designed as pockets. By rotating the drive shaft 9, the chains 11 with the carriers 12 attached to them start to move, as a result of which the melt material is transported upwards on the sliding floor 7. At the emptying point 8, which is formed by the end of the sliding floor 7, there is a driver lifting device provided, through which each driver is raised so that it can be completely emptied. At the emptying point 8, the melt material falls from the steep conveyor into the
Furnace 1. The melted material 14 is emptied discontinuously into the storage container 5 of the horizontal conveyor 2 by means of a forklift 15 or by means of a crane. The discharge of the melting material 14 from the storage container 5 is independent of its filling state, and the discharge speed can be adapted to the circumstances. The transport capacity of the horizontal conveyor 2, which can also be arranged at an incline, is more than 10 t / h. The melting material 14 falls into the carriers 12 designed as pockets and is transported upwards continuously or discontinuously. The transport speed can also be adapted to the circumstances. Since only small quantities of melting material 14 are always transported in the driving pockets 12, only small quantities fall into the at the emptying point 8
Furnace 1 so that the furnace is not overloaded in the loading area.
