Description

Die Erfindung betrifft ein Belüftungselement für einen Kühler zum Kühlen von Schüttgut, enthaltend ein mit wenigstens einer Öffnung zur Zufuhr von Kühlgas versehenes wannenartiges Bauteil sowie einen im wannenartigen Bauteil lösbar befestigbaren Einsatz, der eine von unten belüftbare Auflagefläche für das Schüttgut bildet, wobei der Einsatz aus mehreren Längsprofilen und quer dazu angeordneten Verbindungselementen besteht.The invention relates to a ventilation element for a cooler for cooling Bulk material containing one with at least one opening for the supply of cooling gas provided tub-like component and a detachable in the tub-like component attachable insert, which is a bottom surface that can be ventilated for the bulk material forms, with the use of several longitudinal profiles and arranged transversely to it Fasteners exist.

Bei einem Kühler, der beispielsweise zum Kühlen von Zementklinker vorgesehen ist, werden eine Vielzahl derartiger Belüftungselemente neben- und hintereinander angeordnet.

Zum Schluss wird noch eine stirnseitige Abschlussplatte aufgeschraubt. Wenn gleich die Montagekosten bei dieser Lösung deutlich gesenkt werden konnten, ergibt sich bei dieser Variante jedoch der Nachteil, dass ein späterer Austausch einzelner, verschlissener Lamellen nicht mehr möglich ist, da diese aufgrund der Wärmeentwicklungen in den Längsnuten des wannenartigen Bauteils verklemmen.In practice, a ventilation element is used to reduce the high assembly costs known in which the trough-like component is provided with two longitudinal grooves into which Cast slats are inserted, the slats being ventilated Form the support surface for the bulk material. At the end there is also a front Screwed on end plate. If the assembly costs for this solution could be significantly reduced, this variant has the disadvantage, however, that later replacement of individual, worn slats is no longer possible is because of the heat development in the longitudinal grooves of the jam trough-like component.

Der Einsatz 2 sieht Längsprofile 2.1-2.7 sowie Verbindungselemente 2.8-2.11 vor.The insert 2 provides longitudinal profiles 2.1-2.7 and connecting elements 2.8-2.11.

Ein Teil der Längsprofile, nämlich die Längsprofile 2.3-2.7 sind als U-Profile ausgebildet und werden derart angeordnet, dass ein nach oben offenes U-Profil 2.4, 2.6 sich mit einem nach unten offenen U-Profil 2.3, 2.5, 2.7 abwechselt. Die Schenkel benachbarter U-Profile greifen dabei ineinander und bilden zwischen sich einen Belüftungsschlitz. Die nach unten offenen U-Profile 2.3, 2.5, 2.7 stützen sich mit ihren Schenkeln auf den nach oben offenen U-Profilen 2.4 und 2.6 bzw. auf den L-förmig ausgebildeten Längsprofilen 2.1 und 2.2 ab.Part of the longitudinal profiles, namely the longitudinal profiles 2.3-2.7 are as U-profiles are designed and arranged in such a way that an upwardly open U-profile 2.4, 2.6 alternates with a U-profile 2.3, 2.5, 2.7 open at the bottom. The Legs of adjacent U-profiles interlock and form between them a ventilation slot. The U-profiles 2.3, 2.5, 2.7, which are open at the bottom, are supported with their legs on the open U-profiles 2.4 and 2.6 or on the L-shaped longitudinal profiles 2.1 and 2.2 from.

Die nach unten offenen Profile 2.3, 2.5 und 2.7 weisen zu diesen Zweck an ihren Schenkeln beabstandete Ansätze 3.1, 2.5.1 und 2.7.1 auf, die auf den Längsprofilen 2.1, 2.4, 2.6 bzw. 2.2 aufliegen. Zwischen den Ansätzen werden die Belüftungsschlitze 3 ausgebildet. Profiles 2.3, 2.5 and 2.7, which are open at the bottom, indicate their Legs spaced approaches 3.1, 2.5.1 and 2.7.1 on the longitudinal profiles 2.1, 2.4, 2.6 or 2.2 are available. Between the approaches, the Ventilation slots 3 are formed.

Die genaue Positionierung der Längsprofile wird durch die Verbindungselemente 2.8-2.11 gewährleistet. In Fig. 5 ist eines der beiden mittleren Verbindungselemente 2.8, 2.9 und in Fig. 6 eines der beiden stimseitigen Verbindungselemente 2.10 bzw. 2.11 dargestellt. Bei der Montage der beiden mittleren Verbindungselemente 2.8 und 2.9 werden diese in die beiden nach oben offenen U-Profile 2.4 und 2.8 gesteckt, wie das insbesondere Fig. 4 ersichtliche ist. Im Anschluss hieran werden von oben die U-Profile 2.3, 2.5 und 2.7 aufgesteckt. Diese U-Profile sind im Bereich der beiden mittleren Verbindungselemente 2.8 und 2.9 mit Schlitzen 2.3.2, 2.5.2 und 2.7.2 versehen, so dass die beiden mittleren Verbindungselemente 2.8 und 2.9 in ihrer Lage zu den Längsprofilen 2.3, 2.5 und 2.7 fixiert werden. Im Anschluss hieran können die beiden stimseitigen Verbindungselemente 2.10 und 2.11 auf die U-Profile aufgeschoben werden. Die stimseitigen Verbindungselemente sind dabei mit entsprechenden Aufsparungen (siehe Fig. 6) versehen.The exact positioning of the longitudinal profiles is ensured by the connecting elements 2.8-2.11 guaranteed. 5 is one of the two middle connecting elements 2.8, 2.9 and in FIG. 6 one of the two end-side connecting elements 2.10 or 2.11 shown. When installing the two middle connecting elements 2.8 and 2.9 these are plugged into the two open U-profiles 2.4 and 2.8, as that is particularly evident in FIG. 4. Following this, the U-profiles are from above 2.3, 2.5 and 2.7 attached. These U profiles are in the area of the two middle connecting elements 2.8 and 2.9 with slots 2.3.2, 2.5.2 and 2.7.2 provided so that the two middle connecting elements 2.8 and 2.9 in their Position to the longitudinal profiles 2.3, 2.5 and 2.7 can be fixed. Following this can the two end-side connecting elements 2.10 and 2.11 on the U-profiles be postponed. The front-side connecting elements are included appropriate savings (see Fig. 6).

Die nach oben weisenden Flächen der U-Profile 2.3, 2.5 und 2.7 werden je nach Anwendung mit besonderen Verschleißschutzelementen 4 versehen, wobei die U-Profile in diesem Bereich mit Durchbrüchen 2.3.3, 2.5.3 bzw. 2.7.3 versehen sind, wie insbesondere aus den Fig. 3 und 4 hervorgeht. Diese Durchbrüche ermöglichen eine direkte Kühlung der Verschleißschutzelemente 4. Die Verschleißschutzelemente 4 werden beispielsweise mittels Schweißung im Bereich dieser Durchbrüche an den U-Profilen befestigt.The upward-facing surfaces of the U-profiles 2.3, 2.5 and 2.7 are depending on Application with special wear protection elements 4, the U-profiles breakthroughs 2.3.3, 2.5.3 and 2.7.3 are provided in this area, as can be seen in particular from FIGS. 3 and 4. Allowing these breakthroughs direct cooling of the wear protection elements 4. The wear protection elements 4, for example, by welding in the area of these openings U-profiles attached.

Wie insbesondere in Fig. 4 zu erkennen ist, ergeben sich aufgrund der abgerundeten Ecken der U-Profilen und der geraden Verschleißplatten 4 im Übergangsbereich sogenannte Zwickel 5. Die stimseitigen Verbindungselemente 2.11 weisen zu diesem Zweck entsprechend Komplementär ausgebildete Nasen 2.11.1 auf.As can be seen in particular in FIG. 4, the result of the rounded Corners of the U-profiles and the straight wear plates 4 in the transition area so-called gusset 5. The front-side connecting elements 2.11 point to this Purpose of complementary trained noses 2.11.1.

Der Einsatz 2 besteht vorzugsweise aus geformten Blechprofilen. Die Nuten und Ausnehmungen der Verbindungselemente 2.8-2.11 sind dabei so bemessen, dass ein einfaches, aber möglichst spielarmes Aufschieben und Zusammenfügen der Einzelteile möglich ist. Vor der Montage des zusammengesteckten Einsatzes mit dem wannenartigen Bauteil 1 sind die Einzelteile des Einsatzes, je nach Toleranzen zueinander etwas beweglich. Da diese Beweglichkeit im späteren Einsatz unerwünscht ist, ist die nachfolgend beschriebene, kraft- und formschlüssige Verbindung des Einsatzes mit dem wannenartigen Bauteil 1 vorgesehen.The insert 2 preferably consists of shaped sheet metal profiles. The grooves and Recesses of the connecting elements 2.8-2.11 are dimensioned so that a simple, but as little play as possible sliding and assembling the Individual parts is possible. Before assembling the insert with the tub-like component 1 are the individual parts of the insert, depending on the tolerances slightly movable to each other. Because this agility in later use is undesirable, the non-positive and positive described below Connection of the insert provided with the tub-like component 1.

Der Einsatz 2 wird über die beiden L-Profile 2.1 und 2.2 mit dem wannenartigen Bauteil 1 verschraubt. Die beiden L-Profile 2.1 und 2.2 sind zu diesem Zweck mit jeweils zwei Bohrungen 2.1.1 bzw. 2.2.1 versehen.The insert 2 is over the two L-profiles 2.1 and 2.2 with the tub-like Component 1 screwed. For this purpose, the two L-profiles 2.1 and 2.2 are included Provide two holes 2.1.1 and 2.2.1, respectively.

Die beiden L-Profilen werden mit ihren einen Schenkeln in entsprechende Nuten 2.11.2 bzw. 2.11.3 der stirnseitigen Verbindungselemente 2.11 bzw. 2.10 eingeschoben. Während die beiden Schenkel des L-Profile 2.1 und 2.2 einen Winkel von 90° einschließen, sind die Nuten 2.11.2. und 2.11.3 gegenüber der horizontalen so ausgerichtet, dass sie einen Winkel α einschließen, der etwas größer als 90° ist. Wird der Einsatz 1 bei der Montage im wannenartigen Bauteil 1 angeordnet, so sind die beiden mit dem Bodenteil 1.2 in Kontakt kommenden Schenkel der beiden L-Profile 2.1 bzw. 2.2 nicht parallel zum Bodenteil ausgerichtet, sondern bilden mit dem Bodenteil einen kleinen Winkel. Durch die Verschraubung der beiden L-Profile mit dem Bodenteil 1.2 werden die beiden Schenkel der L-Profile auf den Bodenteil 1.2 gedrückt, sodass ein definiertes Biegemoment hervorgerufen wird, wodurch eine kraft- und formschlüssige Verbindung des Einsatzes mit dem wannenartigen Bauteil entsteht, sodass eine genaue Lagesicherung des Einsatzes 2 im wannenartigen Bauteil 1 sowie der Einzelteile des Einsatzes untereinander bewirkt wird.The two L-profiles are with one leg in corresponding grooves 2.11.2 or 2.11.3 of the front connecting elements 2.11 or 2.10 inserted. While the two legs of the L-profiles 2.1 and 2.2 make an angle of 90 °, the grooves are 2.11.2. and 2.11.3 compared to the horizontal aligned so that they enclose an angle α that is slightly larger than 90 °. If the insert 1 is arranged in the tub-like component 1 during assembly, then the two legs of the two L-profiles coming into contact with the base part 1.2 2.1 and 2.2 are not aligned parallel to the bottom part, but form with the bottom part a small angle. By screwing the two L-profiles with the bottom part 1.2, the two legs of the L-profiles are on the bottom part 1.2 pressed, so that a defined bending moment is caused, whereby a non-positive and positive connection of the insert with the tub-like component arises, so that an exact position securing of the insert 2 in the tub-like Part 1 and the individual parts of the insert is effected with each other.

Aus Fig. 1 ist zu erkennen, dass die Längsprofile und die quer dazu angeordneten Verbindungselemente eine Auflagefläche für das Schüttgut bilden, die sich durch mehrere, nach oben offene, kastenartige Abteile auszeichnet. In diesem Abteilen wird sich im Betrieb der Belüftungselemente Schüttgut ansammeln und dadurch eine natürliche Verschleißschutzschicht bilden. From Fig. 1 it can be seen that the longitudinal profiles and those arranged transversely thereto Fasteners form a support surface for the bulk material, which is characterized by distinguishes several, box-like compartments open at the top. In this compartment bulk material will accumulate in the operation of the ventilation elements and thereby one form a natural wear protection layer.

Die Einzelteile des oben beschriebenen Einsatzes werden lediglich zusammengesteckt, um dann als ganzes mit dem wannenartigen Bauteil verschraubt zu werden. Im Rahmen der Erfindung wäre es jedoch denkbar, dass die Einzelteile gesteckt und im Bereich der stirnseitigen Verbindungselemente mittels Schweißung angeheftet werden.The individual parts of the insert described above are only put together, then screwed together as a whole with the tub-like component to become. Within the scope of the invention, however, it would be conceivable that the individual parts inserted and in the area of the front connecting elements by means of welding to be pinned.

Bei den der Erfindung zugrundeliegenden Versuchen hat sich gezeigt, dass die Kosten für die Herstellung der Belüftungselemente durch das Zusammenstecken der Einzelteile und anschließende Anheften an den Fügestellen um bis zur 30% gesenkt werden können. Für die oben ausführlich beschriebene Variante, bei der auf eine Schweißung verzichtet wird, betragen die Kosteneinsparungen sogar 40%.In the experiments on which the invention is based, it has been shown that the Cost of producing the ventilation elements by plugging the Individual parts and subsequent tacking at the joints reduced by up to 30% can be. For the variant described in detail above, in which a If welding is dispensed with, the cost savings are as much as 40%.
