Furthermore, a considerable amount of cleaning work has to be carried out in order to maintain a constantly clean production area, in particular a coating pan which is always clean inside.
  • a coating wall has also already been proposed (see in "The Pharmaceutical Industry” 42, 3, 297-305, 1980), which runs parallel to the opening of the coating pan in the area.

Since the probes are subjected to constant deflections and vibrations by the raw dragées in the coating pan, a perfect seal of the probe bushings cannot be achieved by a cover plate for the coating pan opening. Probes arranged in this way also hinder cleaning work in the coating pan. Therefore, a coating wall has already been proposed, the upper part of which is drawn vertically down into the coating pan opening.

Description

Die Erfindung betrifft eine Dragierwand zur Trennung des schwarzen Technikbereichs vom grauen Produktionsbereich eines Dragierkessels.The invention relates to a coating wall for separating the black technical area from the gray production area of a coating pan.

Zweck einer solchen Dragierwand ist es, den Lärmpegel im Raum, insbesondere im Produktionsbereich, zu reduzieren, die Produkthygiene zu verbessern und Staub- und Sprühnebel im Raum, insbesondere im Produktionsbereich, zu verhindern. Der entstehende Lärm wird dabei nicht nur von dem Antriebsaggregat des Dragierkessels, sondern auch von der Bewegung der Rohdragees im Dragierkessel und der dort stattfindenden Beaufschlagung mit Dragierstoffen und Belüftung über Sonden erzeugt. Die Beaufschlagung mit Dragierstoffen im Dragierkessel erzeugt desweitern Staub- und Sprühnebel, die die Neigung haben, aus der Dragierkesselöffnung in den Raum auszutreten.The purpose of such a coating wall is to reduce the noise level in the room, in particular in the production area, to improve product hygiene and to prevent dust and spray mist in the room, in particular in the production area. The resulting noise is not only generated by the drive unit of the coating pan, but also by the movement of the raw dragees in the coating pan and the exposure to coating substances and ventilation there, which are carried out by means of probes. The exposure to coating substances in the coating pan also produces dust and spray mist, which have a tendency to emerge into the room from the coating pan opening.

Zur Senkung des Lärmpegels wurde schon eineAussenbeschichtung des Dragierkessels mit lärmdämmendem Material vorgeschlagen. Schliesslich sollte jeder Dragierkessel nach einer herkömmlichen Lösung in eine eigene Box mit Türen gestellt werden. Diese Lösung hat die Nachteile, dass im grauen Produktionsraum auch der eigentlich zum schwarzen Technikbereich gehörende Motor und das Getriebe des Dragierkessels sowie sämtiche Zuführschläuche für die Luft und die Sonden angebracht sind. Daduch wird die Produkthygiene nachteilig beeinflusst. Desweiteren ist ein erheblicher Aufwand an Reinigungsarbeit zu erbringen, um einen stets sauberen Produktionsraum, inbesondere einen im Inneren stets sauberen Dragierkessel zu erhalten.To reduce the noise level, an outer coating of the coating pan with noise-reducing material has already been proposed. After all, each coating pan should be placed in its own box with doors using a conventional solution. This solution has the disadvantages that the motor, which is actually part of the black technology area, and the gearbox of the coating pan, as well as all supply hoses for the air and the probes, are installed in the gray production area. This adversely affects product hygiene. Furthermore, a considerable amount of cleaning work has to be carried out in order to maintain a constantly clean production area, in particular a coating pan which is always clean inside.

Es wurde auch schon eine Dragierwand vorgeschlagen (siehe in «Die Pharmazeutische Industrie» 42, 3, 297-305, 1980), die im Bereich der Dragierkesselöffnung parallel zu dieser verläuft. Dazu mussten aber dann die Sonden über die graue Zone durch die Dragierkesselöffnung in den Dragierkessel geführt werden. Da die Sonden von den Rohdragees im Dragierkessel ständigen Ablenkungen und Vibrationen unterworfen werden, lässt sich eine einwandfreie Abdichtung der Sondendurchführungen durch eine Abdeckplatte für die Dragierkesselöffnung nicht erreichen. Auch behindern solchermassen angeordnete Sonden Reinigungsarbeiten im Dragierkessel. Daher wurde auch schon eine Dragierwand vorgeschlagen, deren Oberteil senkrecht bis in die Dragierkesselöffnung herabgezogen ist. Hinter der Dragierwand sollten dann wie herkömmlicherweise die Sonden von oben in die Dragierkesselöffnung bzw. den Dragierkessel eingeführt werden. Der Nachteil einer solchen Lösung liegt jedoch darin, dass dadurch ein erheblicher Teil der Dragierkesselöffnung abgedeckt wird; dadurch wird die Reinigung des Dragierkessels behindert. Schliesslich sind wesentliche Teile der Rückseite der bis in die Dragierkesselöffnung herabgezogenen Dragierwand und der dort verlaufenden Sondenteile für Reinigungsarbeiten nicht direkt zugänglich. Dies alles hat eine schlechte Trennung der schwarzen Zone von der grauen Zone sowie eine eingeschränkte Produkthygiene zur Folge.A coating wall has also already been proposed (see in "The Pharmaceutical Industry" 42, 3, 297-305, 1980), which runs parallel to the opening of the coating pan in the area. To do this, however, the probes then had to be guided across the gray zone through the coating pan opening into the coating pan. Since the probes are subjected to constant deflections and vibrations by the raw dragées in the coating pan, a perfect seal of the probe bushings cannot be achieved by a cover plate for the coating pan opening. Probes arranged in this way also hinder cleaning work in the coating pan. Therefore, a coating wall has already been proposed, the upper part of which is drawn vertically down into the coating pan opening. Behind the coating wall, the probes should then be inserted from above into the coating pan opening or coating pan, as is conventional. The disadvantage of such a solution, however, is that it covers a considerable part of the coating pan opening; this prevents cleaning of the coating pan. Finally, essential parts of the rear of the coating wall, which is pulled down into the coating pan opening, and of the probe parts running there are not directly accessible for cleaning work. All of this results in poor separation of the black zone from the gray zone and reduced product hygiene.

Aus der FR-A-2 137170 ist eine verfahrbare Dragierteilwand zur Trennung des schwarzen Technikbereiches vom grauen Produktionsbereich eines Dragierkessels bekannt, dessen Rotationsachse, wie üblich, aus der Waagrechten heraus geneigt ist und dessen Dragierkesselöffnung in der Ebene senkrecht zur Rotationsachse liegt und in den von oben mindestens eine Sonde ragt, wobei die Dragierwand einen Dragieröffnungsteil aufweist, der vor der Dragierkesselöffnung angeordnet ist. Somit liegt auch die Dragierkesselöffnung nicht mehr senkrecht zum Boden des Produktionsraumes, sondern schräg nach oben offen. Entsprechend dazu ist das Dragieröffnungsteil vor der Dragierkesselöffnung ebenfalls schräg geneigt. Wenn man einmal davon absieht, dass die nach diesem Stand der Technik bekannte Dragier-Teilwand nicht bis zur Decke des Produktionsraumes reicht, so ist festzuhalten, dass sie hohen hygienischen Anforderungen nicht genügt. Die Sondenzuleitungen werden nach diesem Stand der Technik von oben in den Dragierkessel hinein abgewinkelt geführt, um wenigstens im unteren Teil des Dragieröffnungsteiles einen Zugang zum Dragierkessel freizulassen. Jedoch reicht dieser Zugang zum Dragierkessel noch nicht für alle Arbeitszwecke aus; vielmehr ist vorgesehen, dass die Dragierteilwand vom Dragierkessel zusammen mit den Sondenzuleitungen vollkommen weggeschoben werden kann, um die Dragierkesselöffnung völlig freizumachen. Dazu müssen aber die Sondenzuleitungen flexibel ausgestaltet sein. Solche flexiblen Leitungen werden aber nacht allen pharmazeutischen Anforderungen gerecht. So sind flexible Kunststoff- bzw. Gummileitungen regelmässig nicht sauber und inert genug. Metallschläuche müssen demgegenüber zieharmonikaartig ausgebildet werden; daher bieten sie jeder Art von Verunreinigungen beliebige Aufenthaltsräume.From FR-A-2 137170 a movable coating wall for separating the black technical area from the gray production area of a coating pan is known, the rotation axis of which, as usual, is inclined out of the horizontal and the coating pan opening lies in the plane perpendicular to the rotation axis and in that of At least one probe protrudes above, the coating wall having a coating opening part which is arranged in front of the coating pan opening. This means that the coating pan opening is no longer perpendicular to the floor of the production room, but is open at an angle upwards. Accordingly, the coating opening part is also inclined in front of the coating pan opening. If you disregard the fact that the coating part known from this state of the art does not reach the ceiling of the production room, it should be noted that it does not meet high hygienic requirements. According to this prior art, the probe feed lines are angled into the coating pan from above, in order to allow access to the coating pan at least in the lower part of the coating opening part. However, this access to the coating pan is not yet sufficient for all work purposes; rather, it is provided that the coating pan part can be completely pushed away from the coating pan together with the probe feed lines in order to completely clear the coating pan opening. To do this, however, the probe feed lines must be flexible. Such flexible lines meet all pharmaceutical requirements after night. For example, flexible plastic or rubber lines are regularly not clean and inert enough. Metal hoses, on the other hand, have to be designed like an accordion; therefore, they offer any kind of lounge for any kind of contamination.

Der Erfindung liegt die Aufgabe zugrunde, eine Dragierwand zu schaffen, die die Dragierkesselöffnung voll zugänglich belässt und dabei eine einwandfreie Trennung des schwarzen Technikbereichs vom grauen Produktionsbereich beim Dragierkessel gewährleistet.The invention has for its object to provide a coating wall which leaves the coating pan opening fully accessible and thereby ensures a perfect separation of the black technology area from the gray production area in the coating pan.

Diese Aufgabe wird bei einer Dragierwand der im Oberbegriff des Anspruchs 1 genannten Art erfindungsgemäss dadurch gelöst, dass das Dragieröffnungsteil stärker geneigt ist als die Dragierkesselöffnung und dass die von oben in den Dragierkessel ragende(n) Sonde(n) im Bereich des oberen Dragierkesselöffnungsrandes zwischen dem Dragieröffnungsteil und der Dragierkesselöffnung angeordnet ist (sind). Da die Neigung des Dragieröffnungsteiles steiler als diejenige der Dragierkesselöffnung ist, ist es möglich, dass im Bereich des oberen Dragierkesselöffnungsrandes mindestens eine Sonde senkrecht von oben in die Dragierkesselöffnung bzw. den Dragierkessel angeordnet ist. Die Sonde ist dann zwischen dem Dragieröffnungsteil und der Dragierkesselöffnung angeordnet. Dabei kann die Sonde am Oberteil der Dragierwand über einen Halter mit dieser verbunden sein.This object is achieved according to the invention in the case of a coating wall of the type mentioned in the preamble of claim 1 in that the coating opening part is more inclined than the coating pan opening and in that the probe (s) projecting from above into the coating pan in the region of the upper coating pan opening edge between the Coating opening part and the coating pan opening is (are). Since the inclination of the coating opening part is steeper than that of the coating pan opening, it is possible for at least one probe to be arranged vertically from above in the coating pan opening or coating pan in the region of the upper coating pan opening edge. The probe is then between the coating opening part and the dra yaw boiler opening arranged. The probe on the top of the coating wall can be connected to it by a holder.

In einer bevorzugten Ausführungsform ist an dem Dragieröffnungsteil ein Kragen, der sich über den gesamten Umfang der Dragierkesselöffnung bis zu dieser erstreckt, angeordnet. Zur Erläuterung der Kennzeichnung dieser bevorzugten Ausführungsform sei ausgeführt, dass die Öffnung in dem Dragieröffnungsteil der Dragierkesselöffnung entspricht. Somit kann auch gesagt werden, dass der Kragen über den gesamten Umfang der Öffnung in dem Dragieröffnungsteil erstreckt angeordnet ist. Der Kragen schirmt nun einen zylindrischen, keilförmigen Raumteil zwischen der Dragierkesselöffnung und dem Dragieröffnungsteil ab. Dabei ist die Sonde im Bereich des oberen Kragenrandes durch den Kragen hindurchgeführt. Die Sondedurchführung kann durchaus starr ausgebildet sein; daduch wird der Sonde ein zusätzlicher Halt gegeben.In a preferred embodiment, a collar which extends over the entire circumference of the coating pan opening as far as it is arranged on the coating opening part. To explain the identification of this preferred embodiment, it should be stated that the opening in the coating opening part corresponds to the coating pan opening. It can thus also be said that the collar is arranged to extend over the entire circumference of the opening in the coating opening part. The collar now shields a cylindrical, wedge-shaped part of the space between the coating pan opening and the coating opening part. The probe is guided through the collar in the area of the upper collar edge. The probe can be made rigid; this gives the probe an additional hold.

In einer weiteren bevorzugten Ausführungsform ist das Unterteil der Dragierwand nach innen unter das Dragieröffnungsteil geneigt angeordnet.In a further preferred embodiment, the lower part of the coating wall is arranged inclined inwards under the coating opening part.

Insbesondere zur Reduktion des Lärmpegels sind die Einzelelemente der Dragierwand als Mehrschichtplatten ausgebildet, die aus folgenden Lagen bestehen:

  • a) rostfreies Eisen- oder Stahlblech,
  • b) Füllschaum,
  • c) verzinktes Blech,
  • d) Zellgummi mit geschlossener Oberfläche. Dabei weisen die vorgenannten Lagen insbesondere folgende Stärken auf:
  • a) 1 mm rostfreies Eisen- oder Stahlblech,
  • b) 68 mm Füllschaum,
  • c) 1 mm verzinktes Blech,
  • d) 10 mm Zellgummi mit geschlossener Oberfläche.
To reduce the noise level in particular, the individual elements of the coating wall are designed as multilayer panels, which consist of the following layers:
  • a) stainless iron or steel sheet,
  • b) filling foam,
  • c) galvanized sheet,
  • d) Cellular rubber with a closed surface. The aforementioned locations have the following strengths in particular:
  • a) 1 mm rustproof iron or steel sheet,
  • b) 68 mm filling foam,
  • c) 1 mm galvanized sheet,
  • d) 10 mm cellular rubber with a closed surface.

Zur Erfüllung höchster Ansprüche an die Trennung des schwarzen Technikbereichs vom grauen Produktionsbereich ist der Rand des Kragens als die eine Hälfte einer Labyrinthdichtung ausgebildet zur Aufnahme des als andere Hälfte der Labyrinthdichtung ausgebildeten Dragierkesselöffnungsrandes.In order to meet the highest demands on the separation of the black technical area from the gray production area, the edge of the collar is designed as one half of a labyrinth seal to accommodate the edge of the coating pan formed as the other half of the labyrinth seal.

Dabei ist insbesondere der Dichtungsspalt dieser Labyrinthdichtung beim Kragen von einer elastischen Leiste mindestens teilweise abgedeckt und mit Luft beaufschlagt. Als elastische Leiste eignet sich insbesondere eine Leiste aus Gummi oder elastischem Kunststoff. Dadurch, dass der Dichtungsspalt mit Luft beaufschlagt ist, und beim Kragen von der elastischen Leiste mindestens teilweise abgedeckt ist, wird die Luft aus dem Dichtungsspalt der Labyrinthdichtung bevorzugterweise zum Ausgang der Labyrinthdichtung im schwarzen Technikbereich getrieben. Dadurch wird ein Übertritt von Staubteilchen oder Keimen aus dem schwarzen Technikbereich in den grauen Produktionsbereich verhindert.In particular, the sealing gap of this labyrinth seal in the collar is at least partially covered by an elastic strip and exposed to air. A strip made of rubber or elastic plastic is particularly suitable as the elastic strip. Because air is applied to the sealing gap and is at least partially covered by the elastic strip when the collar is used, the air is preferably driven out of the sealing gap of the labyrinth seal to the outlet of the labyrinth seal in the black technical area. This prevents dust particles or germs from moving from the black technology area to the gray production area.

Zur Aufnahme etwaiger Grobteilchen, wie etwa gebrochener Rohdragees, die zufällig in den Dichtungsspalt der Labyrinthdichtung gefallen sind, kann am unteren Kragenrand an einer Sammelleitung ein Sammelbehälter angeordnet sein. In diesen Sammelbehälter fallen somit die groben Teilchen.To collect any coarse particles, such as broken raw dragées, which have accidentally fallen into the sealing gap of the labyrinth seal, a collecting container can be arranged on the lower collar edge on a collecting line. The coarse particles thus fall into this collecting container.

Die Sonde 5 ist an dem Oberteil 4 der Dragierwand mit einem Halter 6 einstückig verbunden angeordnet. Das Oberteil 4 der Dragierwand verläuft senkrecht zwischen der Decke 3 und dem Boden 15, ebenso die auf der Rückseite in der schwarzen Zone 1 liegende Sonde 5. Die Sonde 5 reicht durch die Dragierkesselöffnung 12 bis in den Dragierkessel 10 hinein. Das Dragieröffnungsteil 11 der Dragierwand ist vor der Dragierkesselöffnung 12 zu dieser entsprechend geneigt angeordnet. Die Neigung des Dragieröffnungsteiles 11 ist allerdings steiler als diejenige der Dragierkesselöffnung 12, damit der Sonde 5 im Bereich des oberen Dragierkesselöffnungsrandes 9 genügend Raum bleibt. Mit der Sonde 5 kann das Innere des Dragierkessels 10 mit Dragierstoffen und Druckluft beaufschlagt werden. Im Bereich des unteren Dragierkesselöffnungsrandes 9' ist an dem Dragieröffnungsteil 11 das senkrechte Mittelteil 12a angeordnet. Daran anschliessend ist nach unten das Unterteil 13 angeordnet, das nach innen unter das Dragieröffnungsteil 11 geneigt ausgerichtet ist. Unter dem Unterteil 13 ist schliesslich das Fussteil 16 angeordnet, das die Dragierwand zum Boden 15 abschliesst. Eine Bedienungsperson kann somit mit ihren Füssen unter dem Unterteil 13 stehen, so dass die Kniee der Bedienungsperson zum Mittelteil 12a benachbart angeordnet sein können. So kann die Bedienungsperson so nahe als nur möglich an dem Dragieröffnungsteil 11 stehen, wie dies zur Reinigung erforderlich ist. Da das Dragieröffnungsteil 11 entsprechend der Dragierkesselöffnung 12, und zwar stärker als diese, geneigt ist, ist der Abstand zwischen der Dragierkesselöffnung 12 und dem Dragieröffnungsteil 11 so gering als nur möglich. Somit ist es der Bedienungsperson möglich, so weit in den DragierkesseI 10 vorzudringen, wie es die Reinigung erfordert. Die Öffnung in dem Dragieröffnungsteil 11 kann dabei mindestens so gross sein, wie die Dragierkesselöffnung 12. Wie üblich ist während des Betriebs des Dragierkessels 10 die Öffnung in dem Dragieröffnungsteil 11 durch eine Verschlussplatte zur grauen Zone 2 hin abgedeckt. Eine solche Verschlussplatte besteht gewöhnlich aus hart-elastischem, durchsichtigem Kunststoff. Der Raumbereich entsprechend dem Querschnitt der Dragierkesselöffnung 12 bzw. dem Dragieröffnungsteil 11 wird über den gesamten Umfang der Dragierkesselöffnung 12 von der schwarzen Zone 1 durch einen Kragen 8 abgetrennt. Der Kragen 8 ist somit eine zylindrische Wandung, die in der Höhe keilförmig ausgebildet ist, und zwar liegt das engere Teil des Keiles im Bereich des unteren Kragenrandes 7' bzw. des unteren Dragierkesselöffnungsrandes 9', der breitere bzw. höhere Bereich dieses keilförmigen Kragens 8 liegt dann im Bereich des oberen Kragenrandes 7 bzw. des oberen Dragierkesselöffnungsrandes 9. Die Sonde 5 ist zum oberen Kragenrand 7 benachbart durch den Kragen 8 hindurchgeführt. Die Durchführung kann starr ausgebildet sein, so dass der Sonde 5 im Kragen 8 kein Spiel gegeben ist. Der Kragen 8 ist mit der erfindungsgemässen Dragierwand, insbesondere dem Dragieröffnungsteil 11, einstückig verbunden. Somit wird der vorbeschriebene Raumbereich zwischen dem Dragieröffnungsteil 11 und der Dragierkesselöffnung 12 einwandfrei der grauen Zone 2 zugeordnet und von der schwarzen Zone 1 abgetrennt. Wie in der Figur gezeigt, kann die Dichtung zwischen dem Dragierkesselöffnungsrand und dem Kragenrand als Labyrinthdichtung ausgebildet sein. Dies wird noch anhand von Figur3 näher beschrieben werden.FIG. 1 shows a cross section through a coating pan and the coating wall according to the invention. The cross section passes through the rotation axis of the coating pan and runs vertically between the ceiling 3 and the floor 15 of the room. The black zone is identified by the reference number 1 enclosed in a circle; the gray zone is identified by the reference number 2 enclosed in a circle. In the black zone 1, the drive unit 14 with the coating pan 10 on the axis 11 a and the probe 5 are arranged. The probe 5 is arranged in one piece on the upper part 4 of the coating wall with a holder 6. The upper part 4 of the coating wall runs vertically between the ceiling 3 and the floor 15, as does the probe 5 located on the back in the black zone 1. The probe 5 extends through the coating pan opening 12 into the coating pan 10. The coating opening part 11 of the coating wall is arranged in front of the coating pan opening 12 so that it is inclined accordingly. However, the inclination of the coating opening part 11 is steeper than that of the coating pan opening 12, so that the probe 5 remains in the area of the upper coating pan opening edge 9 sufficient space. With the probe 5, the interior of the coating pan 10 can be charged with coating materials and compressed air. In the area of the lower coating pan opening edge 9 ', the vertical central part 12a is arranged on the coating opening part 11. Subsequently, the lower part 13 is arranged at the bottom, which is inclined inwards under the coating opening part 11. Finally, the foot part 16, which closes the coating wall to the floor 15, is arranged under the lower part 13. An operator can thus stand with his feet under the lower part 13, so that the operator's knees can be arranged adjacent to the central part 12a. Thus, the operator can stand as close as possible to the coating opening part 11, as required for cleaning. Since the coating opening part 11 is inclined correspondingly to the coating pan opening 12, more specifically than this, the distance between the coating pan opening 12 and the coating opening part 11 is as small as possible. Thus, the operator is able to penetrate the coating pan 10 as far as cleaning requires. The opening in the coating opening part 11 can be at least as large as the coating pan opening 12. As is customary during operation of the coating pan 10, the opening in the coating opening part 11 is covered by a closing plate toward the gray zone 2. Such a closure plate usually consists of hard-elastic, transparent plastic. The space corresponding to the cross section of the coating pan opening 12 or the coating opening part 11 is separated from the black zone 1 by a collar 8 over the entire circumference of the coating pan opening 12. The collar 8 is thus a cylindrical wall which is wedge-shaped in height, namely the narrower part of the wedge lies in the area of the lower collar edge 7 'or the lower coating pan opening edge 9', the wider or higher area of this wedge-shaped collar 8 then lies in the area of the upper collar edge 7 or the upper coating pan opening edge 9. The probe 5 is guided through the collar 8 adjacent to the upper collar edge 7. The implementation can be rigid, so that there is no play in the probe 5 in the collar 8. The collar 8 is connected in one piece to the coating wall according to the invention, in particular the coating opening part 11. Thus, the above-described spatial area between the coating opening part 11 and the coating pan opening 12 is correctly assigned to the gray zone 2 and separated from the black zone 1. As shown in the figure, the seal between the coating pan opening edge and the collar edge can be designed as a labyrinth seal. This will be described in more detail with reference to FIG. 3.

In Figur 2 ist der Ausschnitt eines Plattenelementes der erfindungsgemässen Dragierwand im Querschnitt dargestellt. Das Plattenelement ist als Mehrschichtplatte ausgebildet. Auf der Seite der grauen Zone 2 befindet sich das rostfreie Eisen- oder Stahlblech 30. Daran schliesst sich zur schwarzen Zone 1 hin eine Schicht aus Füllschaum 29 an. Bei diesem Füllschaum handelt es sich um einen an sich bekannten schalldämmenden Schaumstoff. Daran schliesst sich verzinktes Blech 28 an. Somit ist der Füllschaum 29 zwischen dem Stahlblech 30 und dem verzinkten Blech 28 eingeschlossen. Auf dem verzinkten Blech 28 ist schliesslich noch zur schwarzen Zone 1 hin eine Schicht aus Zellgummi 34 angeordnet. Die Verbindung zweier Einzelelemente bzw. Plattenelemente der Dragierwand ist ebenfalls in Figur 2 zu erkennen. Dazu wird das verzinkte Blech 28 von der schwarzen Zone 1 weg zur grauen Zone 2 hin abgebogen; zwei somit gebildete Ränder werden von einem Halteelement 31 auf der Seite des Füllschaumes 29 umfasst. Das Zellgummi 34 wird zur Verhinderung von Schmutzbrükken von der schwarzen Zone 1 bis in die graue Zone 2 erstreckt. Entsprechend wird das Stahlblech 30 von der grauen Zone 2 in die schwarze Zone 1 abgebogen und über dem abgebogenen Rand des verzinkten Bleches 28 angeordnet. Die beiden Einzelelemente werden dabei von einem Gegenelement 33 beabstandet. Der Spalt zwischen den beiden Einzelelementen wird zur grauen Zone 2 hin von der Kappe 32 mit Zellgummi 34 abgedeckt.In Figure 2, the section of a plate element of the coating wall according to the invention is shown in cross section. The plate element is designed as a multilayer plate. On the side of the gray zone 2 there is the rustproof iron or steel sheet 30. This is followed by a layer of filling foam 29 towards the black zone 1. This filling foam is a known sound-absorbing foam. This is followed by galvanized sheet 28. The filling foam 29 is thus enclosed between the steel sheet 30 and the galvanized sheet 28. Finally, a layer of cellular rubber 34 is arranged on the galvanized sheet 28 towards the black zone 1. The connection of two individual elements or plate elements of the coating wall can also be seen in FIG. 2. For this purpose, the galvanized sheet 28 is bent away from the black zone 1 towards the gray zone 2; two edges thus formed are encompassed by a holding element 31 on the side of the filling foam 29. The cellular rubber 34 is extended from the black zone 1 to the gray zone 2 to prevent dirt bridges. Correspondingly, the steel sheet 30 is bent from the gray zone 2 into the black zone 1 and is arranged over the bent edge of the galvanized sheet 28. The two individual elements are spaced apart by a counter element 33. The gap between the two individual elements is covered toward the gray zone 2 by the cap 32 with cellular rubber 34.

In Figur 3 ist eine Detailansicht der Labyrinthdichtung zwischen dem Kragen 8 und dem Dragierkesselöffnungsrand dargestellt. Dazu ist am Kragen 8 senkrecht nach aussen von der Kragen- öffnung weg zu dem Kragenmantel die Leitwand 20 abgeformt. An der Leitwand 20 ist über den Luftkanal 19 ein Gebläse 18 angeordnet. Das Gebläse 18 beaufschlagt den Dichtungsspalt 35 mit Luft. Wiederum senkrecht von der Leitwand 20 ist parallel zur Wandung des Kragens 8 die Prallwand 21 abgeformt. Anschliessend ist diese Prallwand 21 parallel zur Leitwand 20 nach innen zur Öffnung des Kragens 8 als Gegenwand 24 abgeformt; dann wird die Gegenwand 24 nochmals parallel zur Prallwand 21 nach aussen zur Öffnung des Kragens 8 in der Rückwand 27 abgeformt. Zum Kragen 8 hin ist der Dichtungsspalt 35 von einer elastischen Leiste 17 mindestens teilweise abgedeckt. Die Leiste 17 muss elastisch sein, da der Dragierkessei 10 stets infolge unterschiedlicher Belastungen aus seiner Ruhelage ausweicht und daher bisweilen erhebliches Spiel benötigt. Die Leiste 17 behindert den Austritt der Luft aus dem Dichtungsspalt 35 zu der Dragierkesselöffnung hin bzw. in den Kragen 8 und somit in die graue Zone. Stattdessen muss die Luft zur schwarzen Zone 1 ausweichen. Zur Vervollständigung der Labyrinthdichtung ist dazu der Dragierkesselöffnungsrand, in der Abbildung der untere Dragierkesselöffnungsrand 9', vom Dragierkessel 10 nach aussen zum Kragen 8 hin abgeformt. Senkrecht vom unteren Dragierkesselöffnungsrand 9' bzw. vom Dragierkesselöffnungsrand ist dann die Aussenwand 25 abgeformt, die in Ruhelage parallel zur Leitwand 20 am Kragen 8 ausgerichtet ist. Die Aussenwand 25 ist dann vor der Prallwand 21 von dieser beabstandet und parallel zu dieser zu der Innenwand 26 abgeformt. Der Weg der aus dem Gebläse 18 austretenden Luft in dem Dichtungsspalt 35 ist durch Pfeile angedeutet. Unten in der Knickung zwischen der Gegenwand 24 und der Prallwand 21 ist an der Sammelleitung 22 der Sammelbehälter 23 angeordnet. In diesen Sammelbehälter 23 können grobe, von der Luftströmung nicht in die schwarze Zone mitgerissene Teilchen fallen.FIG. 3 shows a detailed view of the labyrinth seal between the collar 8 and the edge of the coating pan. For this purpose, the guide wall 20 is molded on the collar 8 vertically outwards from the collar opening to the collar jacket. A fan 18 is arranged on the guide wall 20 via the air duct 19. The fan 18 acts on the sealing gap 35 with air. Again, perpendicular to the guide wall 20, the baffle wall 21 is molded parallel to the wall of the collar 8. This baffle 21 is then molded parallel to the guide wall 20 inwards to open the collar 8 as a counter wall 24; then the counter wall 24 is again shaped parallel to the baffle wall 21 to the outside to open the collar 8 in the rear wall 27. Towards the collar 8, the sealing gap 35 is at least partially covered by an elastic strip 17. The bar 17 must be elastic, since the coating pan 10 always evades its rest position due to different loads and therefore sometimes requires considerable play. The strip 17 prevents the air from escaping from the sealing gap 35 towards the coating pan opening or into the collar 8 and thus into the gray zone. Instead, the air must escape to black zone 1. To complete the labyrinth seal, the coating pan opening edge, in the illustration the bottom coating pan opening edge 9 ', is molded from the coating pan 10 outwards to the collar 8. The outer wall 25 is then formed perpendicularly from the lower coating pan opening edge 9 'or from the coating pan opening edge, which in the rest position is aligned parallel to the guide wall 20 on the collar 8. The outer wall 25 is then spaced from the baffle wall 21 and molded parallel to the inner wall 26. The path of the air emerging from the fan 18 in the sealing gap 35 is indicated by arrows. At the bottom of the bend between the counter wall 24 and the baffle wall 21, the collecting container 23 is arranged on the collecting line 22. Coarse particles which are not entrained by the air flow into the black zone can fall into this collecting container 23.

Die Leiste 17 schliesst mit dem Dragierkesselrand bündig ab. Anstelle des einzelnen Luftkanals 19 kann eine Ringleitung für die Luftbeaufschlagung über dem Umfang der Labyrinthdichtung abgeordnet sein, aus der über viele einzelne über den gesamten Umfang verteilte Luftkanäle 19 die Luft in den Dichtungsspalt geblasen wird.The bar 17 is flush with the coating pan edge. Instead of the individual air duct 19, a ring line for the air supply can be arranged over the circumference of the labyrinth seal, from which the air can be distributed over many individual air ducts 19 over the entire circumference Air is blown into the seal gap.
