Definitions
- the invention relates to a lifting element for tube coolers for at least partially accumulating material, e.g. B. clinker, which has a fixable on the jacket of the tube cooler mounting section and a substantially perpendicular to the driver section.
- a lifting element for tube coolers for at least partially accumulating material e.g. B. clinker
- Such lifting elements are fixed to the jacket of a tube cooler directly or with brackets interposed.
- tube coolers of this type the material to be cooled is taken to a greater or lesser extent when the tube cooler is rotated by lifting elements fixed to the tube jacket, in order to then fall away from these lifting elements and thereby come into intimate contact with cooling air.
- the transport of the material in the cooler R ear occurs due to an inclination in the direction of the exit.
- the tube cooler can be designed as drums and can be combined as a so-called planetary or satellite cooler to form a cooling unit.
- coolers are e.g. needed for cooling clinker in cement production.
- the material to be cooled is usually in the first area of a tube cooler both fine-grained and in more or less large chunks.
- lifting beams or lifting bars are used, which are attached to the jacket of the tube cooler and have a closed driver surface that points essentially towards the center of the tube cooler.
- the object of the invention is to create a lifting element of the type mentioned at the outset with which material accumulating in chunks can be taken along and broken in the first region of a tube cooler.
- the passage opening or the passage openings provided in the driver section cause fine-grained material to fall through the passage opening / passage openings of the driver section, so that the driver surface is not occupied, so that this driver surface can also take chunks of the material to be cooled with rotation of the tube cooler. This breaks the chunks in the area of the tube cooler intended for this purpose and thus reduces the wear stress in the downstream zones of the cooler. It may be expedient to use, in addition to the lifting elements according to the invention, those of the previously known type in a ring. Furthermore, it is possible to provide a ring alone with the lifting elements according to the invention and to equip one or more of the adjacent rings with lifting elements of the known type.
- the invention further provides that the driver section is fork-shaped and each passage opening lies between two tines extending from the fastening section.
- the invention further provides that at least two tines are provided.
- the lifting element according to the invention can also be designed such that the passage opening of the driver section is enclosed by an essentially U-shaped breaking bracket with its two legs extending from the fastening section.
- the use of such a shackle can increase the impact resistance of the lifting element and thus its resistance to falling chunks.
- the lifting element according to the invention can also be designed in such a way that the passage opening enclosed by the breakbar is divided by at least one rib. Such ribs can promote the impact resistance of the driver section and also increase the driver effect.
- a jacket 1 of a tube cooler which has an outer shell 2 made of steel, which is lined on its inside with refractory material 3.
- Lifting elements 5 are connected to the casing 1 and are tightened by anchor screws 6 against a holder 7 which is supported on the inside of the shell.
- the partial section of Fig. 1 relates to a crushing zone located near the inlet of a tube cooler.
- Each lifting element has a fastening section 8 and an almost normal driving section 9. These two sections 8, 9 give the lifting element an essentially L-shaped shape.
- the fastening section 8 is here provided with two lugs 10 which engage in the holder 7 in the assembled state.
- the approaches 10 are provided with openings 11 for the anchor bolts 6.
- the driver section 9 is delimited by a break bar 12 which has a central section 13 and two adjoining it, in Direction on the fastening portion 8 has diverging legs 14.
- the crushing bar 12 thus, together with the fastening section 8, delimits a passage opening 15.
- a rib 16 which starts from the fastening section 8 and extends to the central section 13 of the crushing bracket 12, divides the passage opening 15 into two equal parts. Furthermore, support ribs 17 are provided, which also extend from the fastening section 8 and support the legs 14 of the crusher bar 12.
- the surfaces of the middle section 13 and the leg 14 lie essentially in one plane, while the surface of the rib 16 is offset inwards.
- the lifting element is a one-piece casting made of heat-resistant cast steel.
- the crushing bracket 12 consequently remains essentially free and is therefore suitable for taking with it chunk-like material to be cooled which then falls from an elevated position from the driver section 9 and strikes the central section 13 of a lifting element which is then in the falling line and is thereby broken and crushed can.
- FIG. 6 and 7 relate to a further embodiment of the lifting element according to the invention, which differs from the previously described embodiment solely in the design of the driver section 20.
- This driver section 20 is here from a total of three from the fastening section 8 outgoing tines 21-23 are formed, of which the outer tines 21, 23 converge slightly starting from the fastening section 8. Between the prongs 21-23, passage openings 24, 25 remain free, through which fine-grained material can fall through, in order also to allow a sufficiently safe taking away of lumpy material in this embodiment.

Description
Die Erfindung betrifft ein Hubelement für Rohrkühler für zumindest teilweise in Brocken anfallendes Material, z. B. Klinker, das einen am Mantel des Rohrkühlers fixierbaren Befestigungsabschnitt und einen im wesentlichen rechtwinklig dazu verlaufenden Mitnehmerabschnitt aufweist.The invention relates to a lifting element for tube coolers for at least partially accumulating material, e.g. B. clinker, which has a fixable on the jacket of the tube cooler mounting section and a substantially perpendicular to the driver section.
Derartige Hubelemente werden am Mantel eines Rohrkühlers unmittelbar oder unter Zwischenschaltung von Halterungen festgelegt.Such lifting elements are fixed to the jacket of a tube cooler directly or with brackets interposed.
In derartigen Rohrkühlern wird das zu kühlende Material bei der Drehung des Rohrkühlers von am Rohrmantel festgelegten Hubelementen mehr oder weniger weit mitgenommen, um dann von diesen Hubelementen abzufallen und dabei mit Kühlluft in innige Berührung zu kommen. Der Transport des Materials in dem Rohrkühler erfolgt aufgrund einer Neigung in Richtung auf den Ausgang.In tube coolers of this type, the material to be cooled is taken to a greater or lesser extent when the tube cooler is rotated by lifting elements fixed to the tube jacket, in order to then fall away from these lifting elements and thereby come into intimate contact with cooling air. The transport of the material in the cooler R ear occurs due to an inclination in the direction of the exit.
Die Rohrkühler können als Trommeln ausgebildet sein und als sogenannte Planeten- oder Satellitenkühler zu einer Kühleinheit zusammengeschlossen sein.The tube cooler can be designed as drums and can be combined as a so-called planetary or satellite cooler to form a cooling unit.
Derartige Kühler werden z.B. für die Kühlung von Klinker bei der Zementherstellung benötigt.Such coolers are e.g. needed for cooling clinker in cement production.
Das zu kühlende Material liegt in dem ersten Bereich eines Rohrkühlers in der Regel sowohl feinkörnig wie auch in mehr oder weniger großen Brocken vor. In diesem ersten Bereich des Rohrkühlers werden Hubbalken oder Hubleisten verwendet, die an Mantel des Rohrkühlers angebracht sind und eine geschlossene, im wesentlichen in Richtung auf das Zentrum des Rohrkühlers weisende Mitnehmerfläche haben. Es kann nun beobachtet werden, daß sich auf der Mitnehmerfläche ausgehend von dem jeweiligen Schüttwinkel des Materials nur der feinkörnige Anteil des Materials ansammelt. Dieses auf der Mitnehmerfläehe befindliche feinkörnige Material verhindert weitgehend, daß die Hubelemente auch gröberes Material oder Brocken mitnehmen können. Dies hat zur Folge, daß das in Brockenform vorliegende Material nicht in ausreichender Weise mitgenommen wird und nicht in dem gewünschten Ausmaße gekühlt wird. Weiter ergibt sich, daß durch die mangelhafte Mitnahme des brokkenförmigen Materials die erwünschte Zertrümmerung dieses Materials nicht in ausreichendem Maße eintritt, da diese Zertrümmerung von dem Herabfallen der Materialbrocken abhängt, was wiederum erst dann eintritt, wenn die Brocken in eine erhöhte Position mitgenommen worden sind. Bei den bisher bekannten Hubelementen besteht also der Nachteil, daß Brocken bis in die nachgeschalteten Bereiche des Rohrkühlers mitgenommen werden, ohne ausreichend gekühlt zu sein. Diese nicht ausreichende Kühlung kann Nachteile für das Material selbst haben. Darüber hinaus führt aber das Vorhandensein von Brokken in den nachgeschalteten Bereichen leicht zu starkem Verschleiß und zur Zerstörung der in diesen Bereichen befindlichen Hubelemente.The material to be cooled is usually in the first area of a tube cooler both fine-grained and in more or less large chunks. In this first area of the tube cooler, lifting beams or lifting bars are used, which are attached to the jacket of the tube cooler and have a closed driver surface that points essentially towards the center of the tube cooler. It can now be observed that, starting from the respective angle of repose of the material, only the fine-grained portion of the material accumulates on the driver surface. This fine-grained material located on the driving surface largely prevents the lifting elements from being able to take along coarser material or lumps. As a result, the material in the form of chunks is not taken along sufficiently and is not cooled to the desired extent. Furthermore, it follows that the desired breakdown of the material does not occur to a sufficient extent as a result of inadequate entrainment of the broken material, since this breakdown depends on the falling off of the material lumps, which in turn only occurs when the lumps have been taken to an elevated position. In the case of the lifting elements known hitherto, there is the disadvantage that chunks are taken into the downstream areas of the tube cooler without being sufficiently cooled. This insufficient cooling can have disadvantages for the material itself. Beyond that, the presence of Brok leads ken in the downstream areas easily excessive wear and destruction of the lifting elements located in these areas.
Der Erfindung liegt nun die Aufgabe zugrunde, ein Hubelement der eingangs erwähnten Art zu schaffen, mit dem in Brocken anfallendes Material im ersten Bereich eines Rohrkühlers mitgenommen und gebrochen werden kann.The object of the invention is to create a lifting element of the type mentioned at the outset with which material accumulating in chunks can be taken along and broken in the first region of a tube cooler.
Diese Aufgabe wird bei einem Hubelement der eingangs erwähnten Art neuerungsgemäß dadurch gelöst, daß der Mitnehmerabschnitt mindestens eine durch diesen Abschnitt hindurchgehende Durchlaßöffnung hat.This object is achieved with a lifting element of the type mentioned at the outset in that the driver section has at least one passage opening passing through this section.
Die in dem Mitnehmerabschnitt vorgesehene Durchlaßöffnung bzw. die Durchlaßöffnungen bewirken, daß feinkörniges Material durch die Durchlaßöffnung / Durchlaßöffnungen des Mitnehmerabschnitts hindurchfällt, die Mitnehmerfläche also nicht besetzt, so daß diese Mitnehmerfläche auch Brocken des zu kühlenden Materials bei Drehung des Rohrkühlers mitnehmen kann. Es kommt dabei in dem dafür vorgesehenen Bereich des Rohrkühlers zu einem Brechen der Brocken und damit zu einer Verringerung der Verschleißbeanspruchung in den nachgeschalteten Zonen des Kühlers. Es kann zweckmäßig sein, in einem Ring zusätzlichzu den erfindungsgemäßen Hubelementen auch solche der bisher bekannten Art einzusetzen. Ferner ist es möglich, einen Ring allein mit den erfindungsgemäßen Hubelementen zu versehen und einen oder mehrere der benachbarten Ringe mit Hubelementen der bekannten Art auszustatten.The passage opening or the passage openings provided in the driver section cause fine-grained material to fall through the passage opening / passage openings of the driver section, so that the driver surface is not occupied, so that this driver surface can also take chunks of the material to be cooled with rotation of the tube cooler. This breaks the chunks in the area of the tube cooler intended for this purpose and thus reduces the wear stress in the downstream zones of the cooler. It may be expedient to use, in addition to the lifting elements according to the invention, those of the previously known type in a ring. Furthermore, it is possible to provide a ring alone with the lifting elements according to the invention and to equip one or more of the adjacent rings with lifting elements of the known type.
Die Erfindung sieht ferner vor, daß der Mitnehmerabschnitt gabelförmig ausgebildet ist und jede Durchlaßöffnung zwischen zwei von dem Befestigungsabschnitt ausgehenden Zinken liegt. Die Erfindung sieht ferner vor, daß mindestens zwei Zinken vorgesehen sind.The invention further provides that the driver section is fork-shaped and each passage opening lies between two tines extending from the fastening section. The invention further provides that at least two tines are provided.
Das erfindungsgemäße Hubelement kann ferner so ausgebildet sein, daß die Durchlaßöffnung des Mitnehmerabschnitts von einem im wesentlichen U-förmigen mit seinen beiden Schenkeln von dem Befestigungsabschnitt ausgehenden Brechbügel umschlossen ist. Die Verwendung eines solchen Brechbügels kann die Stoßfestigkeit des Hubelements und damit die Widerstandsfähigkeit gegenüber herabfallenden Brocken erhöhen.The lifting element according to the invention can also be designed such that the passage opening of the driver section is enclosed by an essentially U-shaped breaking bracket with its two legs extending from the fastening section. The use of such a shackle can increase the impact resistance of the lifting element and thus its resistance to falling chunks.
Das erfindungsgemäße Hubelement kann ferner so ausgebildet sein, daß die von dem Brechbügel umschlossene Durchlaßöffnung durch mindestens eine Rippe aufgeteilt ist. Durch derartige Rippen kann die Stoßfestigkeit des Mitnehmerabschnitts gefördert und auch der Mitnehmereffekt erhöht werden.The lifting element according to the invention can also be designed in such a way that the passage opening enclosed by the breakbar is divided by at least one rib. Such ribs can promote the impact resistance of the driver section and also increase the driver effect.

In Fig. 1 ist ein Teil eines Mantels 1 eines Rohrkühlers dargestellt, der eine äußere Schale 2 aus Stahl aufweist, die auf ihrer Innenseite mit feuerfestem Material 3 ausgekleidet ist. An den Mantel 1 sind Hubelemente 5 angeschlossen, welche von Ankerschrauben 6 gegen eine Halterung 7 angezogen werden, die sich auf der Innenseite der Schale abstützt.In Fig. 1, part of a jacket 1 of a tube cooler is shown, which has an
Der Teilschnitt nach Fig. 1 betrifft eine nahe dem Einlaß eines Rohrkühlers befindliche Brechzone.The partial section of Fig. 1 relates to a crushing zone located near the inlet of a tube cooler.
Jedes Hubelement hat einen Befestigungsabschnitt 8 und einen nahezu normal dazu verlaufenden Mitnehmerabschnitt 9. Diese beiden Abschnitte 8,9 geben dem Hubelement eine im wesentlichen L-förmige Gestalt.Each lifting element has a

Der Mitnehmerabschnitt 9 wird bei der Ausführungsform nach dem Fig. 1 bis 4 von einem Brechbügel 12 begrenzt, der einen Mittelabschnitt 13 und zwei sich daran anschließende, in Richtung auf den Befestigungsabschnitt 8 divergierende Schenkel 14 hat. Der Brechbügel 12 begrenzt somit gemeinsam mit dem Befestigungsabschnitt 8 eine Durchlaßöffnung 15.In the embodiment according to FIGS. 1 to 4, the

Wenn nun ein ·solches Hubelement in die Brechzone eines Rohrkühlers eingebaut ist, dann kann sich auf diesem Hubelement kein feinkörniges Material ansammeln, da solches Material durch die Durchlaßöffnung 15 hindurch abfällt. Der Brechbügel 12 bleibt demzufolge im wesentlichen frei und ist deshalb geeignet, brockenförmiges vorliegendes zu kühlendes Material mitzunehmen, das dann aus einer erhöhten Position von dem Mitnehmerabschnitt 9 herabfällt und auf den Mittelabschnitt 13 eines dann in der Fallinie befindlichen Hubelements auftrifft und dadurch gebrochen und zerkleinert werden kann.If such a lifting element is now installed in the crushing zone of a tube cooler, then no fine-grained material can accumulate on this lifting element, since such material falls through the passage opening 15.

Dieser Mitnehmerabschnitt 20 wird hier von insgesamt drei vom Befestigungsabschnitt 8 ausgehenden Zinken 21 - 23 gebildet, von denen die äußeren Zinken 21,23 ausgehend vom Befestigungsabschnitt 8 leicht konvergieren. Zwischen den Zinken 21 - 23 bleiben Durchlaßöffnungen 24,25 frei, durch die feinkörniges Material hindurchfallen kann, um auch bei dieser Ausführungsform ein ausreichend sicheres Mitnehmen brockenförmig vorliegenden Materials zu ermöglichen.6 and 7 relate to a further embodiment of the lifting element according to the invention, which differs from the previously described embodiment solely in the design of the
