Beschreibung des AusführungsbeispielsDescription of the embodiment
Der in der Figur 1 mit 10 bezeichnete Extruder dient in der Süßwarenindustrie zum Verarbeiten von Süßwarenmassen. Der Extruder 10 hat ein Gehäuse 11, das an einer Stirnseite mit einem Gehäusedeckel 12 dicht verschlossen ist. Im wesentlichen innerhalb des Gehäuses 11 sind zwei parallel zueinander angeordnete Extruderschnecken 1, 2 angeordnet, deren Antriebsschäfte 3, 4 sich auf der dem Gehäuse 11 abgewandten Seite des Gehäusedeckels 12 befinden. Der Gehäusedeckel 12 weist eine Ausnehmung 13 in Form eines Durchbruches auf. In diese Ausnehmung 13 ist eine Einheit 15, bestehend aus einem hülsenförmigen Dichtungsgehäuse 16, das für jede Extruderschnecke 1, 2 eine Gleitringdichtung 17, 18 umschließt, dichtend einsetzbar. Das Dichtungsgehäuse 16 weist an seinem Innenumfang umlaufende Bunde 19 für jede Gleitringdichtung 17, 18 auf. Die Bunde 19 sind in umlaufenden Ringnuten 21 der Gleitringdichtungen 17, 18 geführt. In die Gleitringdichtungen 17, 18 sind im wesentlichen hülsenförmige Aufnahmewellen 25, 26 für die Antriebsschäfte 3, 4 der Extruderschnecken 1, 2 einsetzbar. Die Länge der Aufnahmewellen 25, 26 ist derart bemessen, daß bei montierten Extruderschnecken 1, 2 zwischen den Stirnseiten der Gleitringdichtungen 17, 18 und den Stirnflächen 23 der Extruderschneckengänge ein axiales Spiel 22 bzw. Abstand ausgebildet ist (siehe Detail der Figur 1) . Dies wird dadurch erreicht, daß die Aufnahmewellen 25, 26 etwas aus den Gleitringdichtungen 17, 18 herausragen.The extruder designated by 10 in FIG. 1 is used in the confectionery industry for processing confectionery masses. The extruder 10 has a housing 11 which is sealed on one end face with a housing cover 12. Two extruder screws 1, 2 arranged parallel to one another are arranged essentially inside the housing 11, the drive shafts 3, 4 of which are located on the side of the housing cover 12 facing away from the housing 11. The housing cover 12 has a recess 13 in the form of a Breakthrough. In this recess 13, a unit 15, consisting of a sleeve-shaped seal housing 16, which encloses a mechanical seal 17, 18 for each extruder screw 1, 2, can be inserted in a sealing manner. The seal housing 16 has circumferential collars 19 for each mechanical seal 17, 18 on its inner circumference. The collars 19 are guided in circumferential annular grooves 21 of the mechanical seals 17, 18. Essentially sleeve-shaped receiving shafts 25, 26 for the drive shafts 3, 4 of the extruder screws 1, 2 can be inserted into the mechanical seals 17, 18. The length of the receiving shafts 25, 26 is dimensioned such that when the extruder screws 1, 2 are mounted, an axial play 22 or distance is formed between the end faces of the mechanical seals 17, 18 and the end faces 23 of the extruder screw flights (see detail in FIG. 1). This is achieved in that the receiving shafts 25, 26 protrude somewhat from the mechanical seals 17, 18.
Die Aufnahmewellen 25, 26 besitzen an ihrem Außenumfang Verzahnungen 27, 28, über die die Extruderschnecken 1, 2 mittels eines nicht dargestellten Antriebs antreibbar sind. Die axiale Fixierung der Extruderschnecken 1, 2 in den Aufnahmewellen 25, 26 erfolgt mittels Befestigungsmuttern 5, 6, die auf die aus den Aufnahmewellen 25, 26 herausragenden Enden der Antriebsschäfte 3, 4 montierbar sind.The receiving shafts 25, 26 have toothings 27, 28 on their outer circumference, via which the extruder screws 1, 2 can be driven by means of a drive (not shown). The extruder screws 1, 2 are axially fixed in the receiving shafts 25, 26 by means of fastening nuts 5, 6, which can be mounted on the ends of the drive shafts 3, 4 protruding from the receiving shafts 25, 26.
Die Aufnahmewellen 25, 26 sind in einem Gestell 29 gelagert, welches seinerseits Führungsaugen 30 aufweist, in denen FührungsStangen 31 geführt sind. Die FührungsStangen 31 sind zusammen mit einer Abschlußplatte 32 am Gehäusedeckel 12 des Extruders 10 befestigt. Zusätzlich ist die Einheit 15 mittels Schrauben 33 mit der zugewandten Stirnseite 34 des Gestells 29 verbindbar. Die oben beschriebene Ausbildung bewirkt, daß die Aufnahmewellen 25, 26 zur Einheit 15 und zur Ausnehmung 13 in dem Gehäusedeckel 12 ausgerichtet sind. Zum Ausbau der Extruderschnecken 1, 2 aus dem Gehäuse 11 müssen lediglich die Befestigungsmuttern 5, 6 abgeschraubt werden, so daß die Extruderschnecken 1, 2 aus den Aufnahmewellen 25, 26 herausgezogen werden können (Figur 2) . Dabei sind die Extruderschnecken 1, 2 von den Gleitringdichtungen 17, 18 mechanisch entkoppelt, d.h. daß keinerlei Belastungen / Beschädigungen über die Extruderschnecken 1, 2 auf dieThe receiving shafts 25, 26 are mounted in a frame 29, which in turn has guide eyes 30, in which guide rods 31 are guided. The guide rods 31 are fastened together with an end plate 32 to the housing cover 12 of the extruder 10. In addition, the unit 15 can be connected to the facing end face 34 of the frame 29 by means of screws 33. The design described above causes the receiving shafts 25, 26 to be aligned with the unit 15 and the recess 13 in the housing cover 12. To remove the extruder screws 1, 2 from the housing 11, only the fastening nuts 5, 6 have to be unscrewed, so that the extruder screws 1, 2 can be pulled out of the receiving shafts 25, 26 (FIG. 2). The extruder screws 1, 2 are mechanically decoupled from the mechanical seals 17, 18, which means that there are no loads / damage to the extruder screws 1, 2 on the
Gleitringdichtungen 17, 18 erfolgen können. Der Einbau der Extruderschnecken 1, 2 erfolgt sinngemäß in umgekehrter Reihenfolge. Auch dabei ist ein Kontakt der Extruderschnecken 1, 2 bzw. deren Antriebsschäften 3, 4 mit den Gleitringdichtungen 17, 18 aufgrund der Antriebswellen 25, 26 und zusätzlich aufgrund des axialen Spiels 22 zu den Stirnflächen 23 der Extruderschneckengänge unmöglich.Mechanical seals 17, 18 can be made. The extruder screws 1, 2 are installed in the reverse order. It is also impossible for the extruder screws 1, 2 or their drive shafts 3, 4 to come into contact with the mechanical seals 17, 18 due to the drive shafts 25, 26 and additionally due to the axial play 22 to the end faces 23 of the extruder screw flights.
Wenn die Gleitringdichtungen 17, 18 ausgetauscht werden sollen, so wird das Gestell 29 (nach dem Ausbau derIf the mechanical seals 17, 18 are to be replaced, the frame 29 (after removal of the
Extruderschnecken 1, 2) in den FührungsStangen 31 vom Gehäusedeckel 12 des Extruders 10 wegbewegt, wobei die Einheit 15 aus der Ausnehmung 13 gezogen wird. Anschließend können die Schrauben 33 gelöst werden, so daß die Einheit 15 samt Gleitringdichtungen 17, 18 demontiert sind (Figur 3). Extruder screws 1, 2) in the guide rods 31 are moved away from the housing cover 12 of the extruder 10, the unit 15 being pulled out of the recess 13. Then the screws 33 can be loosened so that the unit 15 together with the mechanical seals 17, 18 are dismantled (FIG. 3).
