Abstract
Description
Die Erfindung betrifft ein Drainageelement für Pressen zum Ausscheiden von Flüssigkeiten aus festen Stoffen, insbesondere für Obst-, Trauben- oder Früchtepressen, bestehend aus einem in einer mit dem Behältermantel verbundenen Fassung befestigten, stabförmig ausgebildeten und von einer flüssigkeitsdurchlässigen Filterhülle umgebenen flexiblen Kern.The invention relates to a drainage element for presses for separating liquids from solid substances, in particular for fruit, grape or fruit presses, consisting of a flexible core which is fastened in a socket connected to the container shell and is in the form of a rod and is surrounded by a liquid-permeable filter sleeve.
Eine grössere Anzahl derartiger Drainageelemente ist beispielsweise im Pressraum einer eine pneumatisch betätigbaren Membran aufweisenden Früchtepresse an der Behälterwand über bzw. unter den Saftsammelkanälen angeordnet. Beim Pressen verformen sich die in den Pressraum hineinragenden flexiblen Drainageelemente. Dabei durchdringt der ausgepresste Saft die Filterhülle des Drainageelementes und wird entlang dem stabförmigen Kern aus dem Pressraum herausgeführt und in Saftsammelkanäle geleitet. Hierzu ist das jeweilige Ende des Drainageelementes in einer mit der Behälterwandung verbundenen Fassung lösbar befestigt, wobei der mit Längsrillen zum Transport der Flüssigkeit versehene Kern in einen Saftsammelkanal ragt.A larger number of such drainage elements is arranged, for example, in the pressing chamber of a fruit press having a pneumatically actuated membrane on the container wall above or below the juice collecting channels. During pressing, the flexible drainage elements protruding into the press room are deformed. The squeezed juice penetrates the filter cover of the drainage element and is guided out of the press chamber along the rod-shaped core and directed into juice collection channels. For this purpose, the respective end of the drainage element is detachably fastened in a socket connected to the container wall, the core provided with longitudinal grooves for transporting the liquid protruding into a juice collecting channel.
Zur Befestigung des Kerns ist eine diesen eng umgebende Büchse vorgesehen, die an dem dem Pressraum abgewandten Ende einen gebördelten Rand aufweist und zwischen welcher und der Fassung die um letztere nach aussen umgespülpte strumpfähnliche Filterhülle eingespannt ist, wobei zur Sicherung des Kerns in axialer Richtung ein letzteren durchdringender und an dem gebördelten Rand der Büchse anliegender Stift und zwischen dem Ende des Kerns und dem Boden des Saftsammelkanals eine Einlage vorgesehen ist.For the attachment of the core there is provided a sleeve which closely surrounds it and which has a flanged edge at the end facing away from the pressing chamber and between which and the socket the stocking-like filter sleeve, which is washed around the latter, is clamped, the latter securing the core in the axial direction by a latter penetrating pin and against the flanged edge of the sleeve and between the end of the Core and the bottom of the juice collection channel an insert is provided.
Nachteilig bei dieser bekannten Ausführung ist, dass die Filterhülle im Bereich der Uebergangsstelle, wo das Drainageelement aus der Fassung in den Pressraum ragt, durch den Pressdruck in die längsverlaufenden Abflussnuten des Kerns gepresst werden und so die Drainage beeinträchtigen. An dieser Stelle tritt durch die häufigen Bewegungen des Kerns eine hohe Beanspruchung mit entsprechenden Verschleiss auf.A disadvantage of this known embodiment is that the filter sleeve in the area of the transition point, where the drainage element protrudes from the socket into the press chamber, is pressed into the longitudinal drainage grooves of the core by the pressure and thus impair the drainage. At this point, the frequent movements of the core result in high wear and tear.
Es ist auch schon eine Presse für die Saftgewinnung gemäss CH-A-413'599 (Bucher-Guyer AG) bekannt, welche einen liegenden drehbaren Presszylinder mit einer Druck- und einer Gegendruckplatte umfasst, zwischen welchen Platten flexible Zugorgane gespannt sind, welche aus einem flexiblen Kern und einer saftdurchlässigen, den Pressaft filtrierenden Hülle bestehen. Sowohl die Hülle als auch der flexible Kern sind mit ihren Enden an der Druck- und an der Gegendruckplatte fest verankert, und die gestreckte Länge der Hülle ist grösser als diejenige des flexiblen Kerns.A press for juice extraction according to CH-A-413'599 (Bucher-Guyer AG) is also known, which comprises a horizontal rotatable press cylinder with a pressure plate and a counter-pressure plate, between which plates flexible tension members are tensioned, which consist of a flexible core and a juice-permeable shell that filters the press juice. Both the sheath and the flexible core are firmly anchored at their ends to the pressure and counter-pressure plate, and the stretched length of the sheath is greater than that of the flexible core.
Der Erfindung liegt die Aufgabe zugrunde, die genannten Nachteile zu vermeiden und eine Befestigung des Drainageelementes zu schaffen, deren Herstellung einfach ist und eine rasche Montage und Funktionstauglichkeit erlaubt.The invention has for its object to avoid the disadvantages mentioned and to provide a fastening of the drainage element, the manufacture of which is simple and allows rapid assembly and functionality.
Die Lösung bringt ein Drainageelement der eingangs genannten Art, welches sich dadurch auszeichnet, dass das dem Behältermantel zugewandte Ende des Kerns eine Muffe aufweist, zwischen die und der diese umgebenden Fassung die Filterhülle mittels Haltering in einer Ringnut verankert ist.The solution is provided by a drainage element of the type mentioned at the outset, which is characterized in that the end of the core facing the container shell has a sleeve, between which and the surrounding frame the filter sleeve is anchored in a ring groove by means of a retaining ring.
Nach einem vorteilhaften Merkmal der Erfindung ist der Haltering in einer an der Muffe oder der Fassung vorgesehenen Ringnut angeordnet.
Dadurch kann eine kompakte Bauweise erreicht werden.According to an advantageous feature of the invention, the retaining ring is arranged in an annular groove provided on the sleeve or the socket.
This enables a compact design to be achieved.
Nach einem weiteren Merkmal der Erfindung ist der Haltering als O-Ring ausgebildet.According to a further feature of the invention, the retaining ring is designed as an O-ring.
Zur Schonung der Filterhülle und des Kerns ist die Muffe aus einem elastischen Material gebildet.To protect the filter cover and the core, the sleeve is made of an elastic material.
Vorzugsweise weist die in der Muffe vorgesehene Ringnut einen etwa rechtwinklig zur Zugrichtung der Filterhülle verlaufenden Einstichwinkel (α) auf.The annular groove provided in the sleeve preferably has an insertion angle (α) which is approximately at right angles to the pulling direction of the filter sleeve.
Bei Zugeinwirkung auf die Filterhülle tritt eine elastische Verformung der Ringnut und des O-Ringes auf, wobei der O-Ring als Keil wirkt und die Filterhülle gegen die Flanke der Ringnut presst.When the filter sleeve is subjected to tension, the ring groove and the O-ring are deformed elastically, the O-ring acting as a wedge and pressing the filter sleeve against the flank of the ring groove.
In einer anderen Ausführungsform der Erfindung, bei der die Muffe aus einem weniger oder nicht elastischen Material besteht, ist der Einstichwinkel (α) grösser als 90°.In another embodiment of the invention, in which the sleeve consists of a less or non-elastic material, the insertion angle (α) is greater than 90 °.
Zur axialen Sicherung der Muffe in Richtung des Pressraumes weist die Muffe einen sich in Richtung des Pressraumes verjüngenden Aussenkonus auf, der mit einem entsprechenden Innenkonus der Fassung zusammenwirkt, wobei die Filterhülle zwischen der Muffe und der Fassung angeordnet ist.To axially secure the sleeve in the direction of the press chamber, the sleeve has an outer cone tapering in the direction of the press chamber, which cooperates with a corresponding inner cone of the socket, the filter sleeve being arranged between the socket and the socket.
Die axiale Sicherung der Muffe in Richtung des Flüssigkeitssammelraumes erfolgt durch einen am Ende des Kerns angeordneten, lösbaren Stift, der je eine Bohrung des Kerns und der Fassung durchsetzt.The sleeve is axially secured in the direction of the liquid collecting space by means of a releasable pin which is arranged at the end of the core and passes through a hole in the core and the socket.
Zweckmässigerweise ist zwischen der Muffe und dem Stift eine Endscheibe angeordnet.An end plate is expediently arranged between the sleeve and the pin.
Nach einem weiteren Merkmal der Erfindung übernimmt der Haltering bzw. der O-Ring die Funktion der Abdichtung der Feststoffe aus dem Pressraum.According to a further feature of the invention, the retaining ring or the O-ring takes over the function of sealing the solids from the pressing chamber.
Die mit der Erfindung erzielten Vorteile bestehen auch darin, dass sich aufgrund der Keilwirkung des O-Ringes die Haltekraft mit zunehmender Zugkraft an der Filterhülle erhöht und somit eine sichere Befestigung auch bei hohen Zugkräften gewährleistet ist. Die Konstruktion der Befestigung gestattet eine dünnwandige Gestaltung der Fassung, in die das Drainageelement zur Verankerung ein gesetzt wird. Dadurch ergeben sich niedrige Materialkosten und eine kostengünstige Herstellung. Ausserdem wird die Montage und Demontage der Filterhülle vereinfacht und erleichtert.The advantages achieved with the invention also consist in the fact that, due to the wedge effect of the O-ring, the holding force increases with increasing tensile force on the filter sleeve and thus a secure fastening is ensured even with high tensile forces. The construction of the attachment allows a thin-walled design of the socket, in which the drainage element is used for anchoring. This results in low material costs and inexpensive to manufacture. In addition, the assembly and disassembly of the filter cover is simplified and facilitated.

Wie aus Fig. 1 ersichtlich, sind in einem Pressraum 1 einer nicht näher dargestellten Früchtepresse mehrere Drainageelemente 2 angeordnet. Jedes Drainageelement 2 besteht aus einem stabförmigen, flexiblen Kern 3, der von einer strumpfartigen Filterhülle 4 umgeben ist. Die Enden des Drainageelementes 2 sind in je eine Fassung 6 eingesetzt, die in einer Durchtrittsöffnung 7 des Behältermantels 5 axial unverschiebbar angeordnet ist. Die Fassung 6 ragt mit ihrem längeren Teil in einen Flüssigkeitssammelraum oder Saftsammelkanal 8, der durch eine Wand 9 begrenzt bzw. U-förmig ausgebildet ist. Zur lösbaren Befestigung des Drainageelementes 2 in der Fassung 6 ist ein Stift 10 vorgesehen, der je eine Bohrung der Fassung 6 und des Kerns 3 durchsetzt. Beim Pressvorgang wird ein Pressorgan, bspw. eine Membran gegen die Behälterwand 5 bewegt, wobei die flexiblen Drainageelemente 2 ausknicken und der ausgepresste Saft durch die flüssigkeitsdurchlässige Filterhülle 4 hindurch zum Kern 3 gelangt und über Flüssigkeitskanäle im Kern 3 in den Flüssigkeitssammelraum bzw. Saftsammelkanal 8 geleitet wird.As can be seen from FIG. 1, a plurality of
Zur Befestigung der Filterhülle 4 ist auf das Ende des Kerns 3 eine elastische Muffe 11 aufgeschoben, die einen sich in Richtung des Pressraumes 1 verjüngenden Aussenkonus 12 aufweist. Das Ende der Filterhülle 4 wird über die Muffe 11 gezogen und mit einem als O-Ring 13 ausgebildeten Haltering in einer Ringnut 14 der Muffe 11 festgehalten. Danach wird das Drainageelement 2 von der dem Pressraum 1 abgewandten Seite der Behälterwand 5 aus in die Fassung 6 eingeschoben, bis der Aussenkonus 12 der Muffe 11 mit der übergezogenen Filterhülle 4 an einem entsprechenen Innenkonus 15 der Fassung 6 zur Anlage kommt. Anschliessend an die Muffe 11 ist auf den Kern 3 eine Endscheibe 16 aufgeschoben, an die sich der Stift 10 anschliesst, der die Muffe 11 auf dem Kern 3 axial sichert und, wie bereits beschrieben, das Ende des Drainagelementes 2 in der Fassung 6 fixiert.To fasten the
Die Ringnut 14 in der Muffe 11 weist einen Einstichwinkel (α) von ca. 90° auf (Fig. 2). Der in die Ringnut 14 eingelegte, die Filterhülle 4 überdeckende O-Ring 13 wird durch die Innenwandung der Fassung 6 in der Ringnut 14 gehalten. Durch die beim Pressvorgang stattfindenden elastischen Verformungen des Drainageelementes 2 entstehen an der Befestigungsstelle der Filterhülle 4 erhebliche Zugkräfte, die in Richtung des Pfeiles 17 der Fig. 3 wirken. Infolge dieser Zugkräfte tritt eine elastische Verformung an der in Zugrichtung vorderen Flanke 18 der Ringnut 14 auf, wie in Fig. 3 dargestellt. Der O-Ring 13 rollt sich dabei an der Innenwandung der Fassung 6 in Zugrichtung 17 der Filterhülle 4 ab (Pfeil 19 in Fig. 2 und 3) und wird so verformt, dass er als Keil wirkt und die Filterhülle 4 gegen die Flanke 18 der Ringnut 14 verspannt. Die Verspannung erhöht sich mit zunehmender Zugkraft, so dass auch bei sehr hohen Kräften eine sichere Befestigung der Filterhülle 4 gewährleistet ist.The
Wird für die Muffe 11 ein weniger oder nicht elastisches Material verwendet, so empfiehlt es sich, den Einstichwinkel (α) der Ringnut 14 grösser als 90° (Fig. 4) zu wählen, um den Keileffekt des O-Ringes 13 bei auftretenden Zugkräften zu erzielen. Wie in Fig. 4 dargestellt, wird zwischen der Flanke 18 der Ringnut 14 und der Innenwandung der Fassung 6 eine Keilöffnung gebildet, in die der O-Ring 13 durch Abrollen (Pfeil 19) auf der Innenwandung der Fassung 6 bei Zugeinwirkungen auf die Filterhülle 4 hineingezogen und zu einem Keil verformt wird, der die Filterhülle 4 gegen die Flanke 18 der Ringnut 14 verspannt.If a less or non-elastic material is used for the
