Description

Die Erfindung betrifft ein Drainageelement für Pressen zum Ausscheiden von Flüssigkeiten aus festen Stoffen, insbesondere für Früchtepressen, umfassend einen stabförmigen, flexiblen Drainagekern mit Fliesswegen zum Ableiten der ausgepressten Flüssigkeit aus dem Pressraum und eine den Drainagekern umgebende, flüssigkeitsdurchlässige Filterhülle, wobei mindestens ein Ende des Drainageelementes an einer Saftsammelplatte, Druckplatte oder am Pressmantel der Presse befestigt ist, sowie eine den Drainagekern im Befestigungsbereich und auf einem daran anschliessenden freien Abschnitt umgebende gummielastische Stulpe.The invention relates to a drainage element for presses for separating liquids from solid substances, in particular for fruit presses, comprising a rod-shaped, flexible drainage core with flow paths for draining the squeezed-out liquid from the press space and a liquid-permeable filter sleeve surrounding the drainage core, at least one end of the drainage element is attached to a juice collecting plate, pressure plate or to the press jacket of the press, and a rubber-elastic cuff surrounding the drainage core in the fastening area and on a free section adjoining it.

Fig. 1 zeigt einen Längsschnitt durch die bekannte Befestigung eines Drainageelementes in einer Früchtepresse. In einem durch je eine Druckplatte 1 begrenzten Pressraum 2 einer nicht dargestellten bekannten Früchtepresse sind eine Vielzahl Drainageelemente 3 angeordnet.Fig. 1 shows a longitudinal section through the known attachment of a drainage element in a fruit press. A plurality of drainage elements 3 are arranged in a press space 2, which is delimited by a pressure plate 1, in a known fruit press (not shown).

Ein Drainageelement 3 besteht im wesentlichen aus einem elastischen Drainagekern 4, über dessen aussenliegende Nuten 5, wie der Schnitt A-A zeigt, die Flüssigkeit während des Pressvorganges aus dem Pressraum 2 herausgeleitet wird, und einem darüber gespannten strumpfförmigen Filter 6 zur Fest-Flüssig-Trennung. Jeweils an den Enden des Drainageelementes 3 sind der Drainagekern 4 und der Filter 6 in einem Kernhalter 7 befestigt. Der Filter 6 wird dabei über eine elastische Stulpe 8 geführt und mit einem O-Ring 9 fixiert. Eine Scheibe 10 dient zur Abstützung der Stulpe 8 gegen einen Querstift 11, der seitlich in Bohrungen des Drainagekernes 4 und des Kernhalters 7 geschoben wird, und so die axiale und radiale Fixierung der beiden Bauteile 4 und 7 zueinander gewährleistet.A drainage element 3 consists essentially of an elastic drainage core 4, via the external grooves 5, as the section AA shows, the liquid is led out of the press chamber 2 during the pressing process, and a stocking-shaped filter 6 for solid-liquid separation stretched over it. The drainage core 4 and the filter 6 are fastened in a core holder 7 at the ends of the drainage element 3. The filter 6 will passed over an elastic cuff 8 and fixed with an O-ring 9. A disc 10 serves to support the cuff 8 against a cross pin 11 which is pushed laterally into bores in the drainage core 4 and the core holder 7, thus ensuring the axial and radial fixation of the two components 4 and 7 to one another.

Der Kernhalter 7 wird mithilfe einer Distanzbuchse 12 und eines Sicherungsringes 13 mit der Druckplatte 1 verbunden. Dabei stellt ein Nocken 14 des Sicherungsringes 13, der durch einen Schlitz 15 in der Distanzbuchse 12 in eine Nut 16 des Kernhalters 7 hineingreift, in Verbindung mit einem hinter der Druckplatte 1 liegenden Bund 17 der Distanzbuchse 12 die Sicherung gegen axiales Verschieben her.The core holder 7 is connected to the pressure plate 1 by means of a spacer bush 12 and a locking ring 13. A cam 14 of the locking ring 13, which engages through a slot 15 in the spacer 12 into a groove 16 of the core holder 7, in conjunction with a collar 17 of the spacer 12 lying behind the pressure plate 1, secures against axial displacement.

Wie Fig. 1 erkennen lässt, ist der Filter 6 durch Einklemmen zwischen Kernhalter 7, Stulpe 8 und O-Ring 9 in der Distanzbuchse 12 gehalten. Mindestens die Stulpe 8 ist aus einem elastisch verformbaren Material, vorzugsweise aus einem Elastomer gefertigt. Diese Art der Konstruktion hat folgende Nachteile:

  • a) Die Klemmkräfte haben eine Verringerung des Innendurchmessers der elastischen Stulpe 8 zur Folge, wobei die Klemmkräfte teilweise auch auf den Drainagekern 4 übertragen werden. Da der Drainagekern 4 ebenfalls aus einem elastischen Material besteht, wird er dieser Krafteinwirkung entsprechend bleibend verformt. Der Kerndurchmesser wird kleiner, und der Saftabflussquerschnitt in den Nuten 5 reduziert sich, was den Saftabfluss behindert.
  • b) Beim Ablauf des Pressvorganges wirken unter anderem auch Zugkräfte 20 längs des Filters 6. Da die Stulpe 8 aus einem elastischen Material besteht, wird sie beim Auftreten solcher Zugkräfte 20 oberhalb eines bestimmten Betrages mit dem Filter 6 durch einen Ringspalt gezogen, welcher zwischen dem Kernhalter 7 und dem Drainagekern 4 gebildet ist. Dies hat Betriebsstörungen zur Folge.
  • c) Eine weitere Störungsursache ist dadurch bedingt, dass infolge der Zugkräfte 20 auf dem Filter 6 am Aussenumfang der Stulpe 8 wegen der Reibung zwischen Filter und Stulpe Kräfte in Längsrichtung angreifen. Die Reibung zwischen Stulpe 8 und Drainagekern 4 am Innenumfang der Stulpe hält aber die Stulpe fest, sodass die Längskräfte am Aussenumfang zu einer Längsscherung und damit zu einer Reduktion des Aussendurchmessers der Stulpe 8 führen. Dies wiederum führt dazu, dass die Klemmkraft 22 zwischen Kernhalter 7 und Stulpe 8 zur Fixierung des Filters 6 so weit nachlässt, dass der Filter 6 zwischen den klemmenden Teilen herausgezogen wird. Auch dies hat eine Betriebsstörung zur Folge.
As can be seen in FIG. 1, the filter 6 is held in the spacer 12 by being clamped between the core holder 7, cuff 8 and O-ring 9. At least the cuff 8 is made of an elastically deformable material, preferably an elastomer. This type of construction has the following disadvantages:
  • a) The clamping forces result in a reduction in the inner diameter of the elastic cuff 8, the clamping forces being partially also transmitted to the drainage core 4. Since the drainage core 4 also consists of an elastic material, it is permanently deformed in accordance with this force. The core diameter becomes smaller and the juice drainage cross section in the grooves 5 is reduced, which hinders the juice drainage.
  • b) When the pressing process takes place, tensile forces 20 also act along the filter 6. Since the cuff 8 consists of an elastic material, when such tensile forces 20 occur above a certain amount, it is pulled with the filter 6 through an annular gap, which between the Core holder 7 and the drainage core 4 are formed is. This leads to malfunctions.
  • c) Another cause of the fault is due to the fact that, due to the tensile forces 20 on the filter 6, forces act in the longitudinal direction on the outer circumference of the cuff 8 due to the friction between the filter and the cuff. The friction between the cuff 8 and the drainage core 4 on the inner circumference of the cuff, however, holds the cuff in place, so that the longitudinal forces on the outer circumference lead to longitudinal shearing and thus to a reduction in the outer diameter of the cuff 8. This in turn leads to the fact that the clamping force 22 between the core holder 7 and cuff 8 for fixing the filter 6 decreases so much that the filter 6 is pulled out between the clamping parts. This also results in a malfunction.

Die beschriebenen Nachteile sind also durch die gummielastischen Eigenschaften der genannten Teile bedingt. Auf elastisch verformbare Teile kann aber nicht verzichtet werden, da sonst die Lebensdauer der Filter 6 verkürzt wird.The disadvantages described are therefore due to the rubber-elastic properties of the parts mentioned. However, it is not possible to do without elastically deformable parts, since otherwise the service life of the filter 6 is shortened.

Der Erfindung liegt die Aufgabe zugrunde, die genannten Nachteile durch eine Vorrichtung der eingangs erwähnten Art zu vermeiden.The invention has for its object to avoid the disadvantages mentioned by a device of the type mentioned.

Gemäss der Erfindung wird diese Aufgabe gelöst durch mindestens ein Stützelement für die Stulpe, welches mit derselben so in Verbindung steht, dass ihre Verformbarkeit in einem im Befestigungsbereich liegenden Teilbereich gegenüber dem restlichen Teil stark eingeschränkt ist.According to the invention, this object is achieved by at least one support element for the cuff, which is connected to the cuff in such a way that its deformability in a partial area located in the fastening area is severely restricted compared to the remaining part.

Es erweist sich dabei als besonders vorteilhaft, wenn das Stützelement als Ring mit hoher Biegesteifigkeit ausgebildet ist. Weitere bevorzugte Ausführungsformen sind in den Patentansprüchen gekennzeichnet.It proves to be particularly advantageous if the support element is designed as a ring with high bending rigidity. Further preferred embodiments are characterized in the claims.
