Definitions
- the invention relates to a strainer rod for a substantially cylindrical strainer basket composed of a plurality of strainer rods for the purpose of delimiting a compression space in a screw press for the processing of animal or vegetable products into meat meal and animal fat or vegetable oils and the like.
- Screw presses in equipment for processing animal waste, both as well as vegetable products, for the production of meat meal and animal fat or vegetable oils and the like. Screws are used for this purpose, the core diameter of which increases from the feed opening to the outlet opening, the screw turns being able to be formed in the most varied of embodiments on the outer surface of the screw and forming a compression space.
- the strainer basket enveloping the compression space forms the sieve surface for the liquid to be separated with laid strainer rods, the free exit surfaces being generated by thin spacer plates between the strainer rods.
- the colander rods are inserted from their original rectangular shape - inserted upright - and are generally tapered towards the outside in order to allow the liquid and any fine particles that are carried along to exit.
- This construction requires a relatively thick design of the strainer rods, so that a wide contact surface on the support ribs guarantees against tipping or shifting becomes.
- the cross-sectional shape is formed to the geometric shape of a circular ring sector, so that the naturally available contact surface on the support ribs of the strainer basket cannot be used over the entire area.
- the strainer rods are fastened and thus braced by means of clamping strips which are screwed to the parting line of the strainer basket halves.
- the clamping force for this is more or less linear or point-shaped in the area of the zone of the bars facing the interior and is transmitted via the spacer plates at the narrowest point between them.
- a sanded longitudinal surface in the head area of the rods for transferring the tension to the strainer rods via the spacer plates can prevent the liquid / solid from escaping and sometimes lead to blockages between the rods.
- the present invention deals with the problem of achieving noticeable advantages (reduced fat or oil contents) in the pressed material with an enlarged outlet area and at the same time also considerably simplifying the assembly of strainer rods in the strainer basket.
- strainer rods according to the invention are now provided with spacer ribs by welding or material elevations, which are adapted to the pitch angle (number of required rods per basket) and shaped accordingly.
- the strainer rods lie against each other with the entire surface of the ribs and thus experience one stable seat in the strainer basket, which makes it impossible to move or tilt the strainer rods between the terminal strips.
- the thickness of the strainer rods can be significantly reduced and the number of rods increased accordingly, which leads to a corresponding increase in the effective liquid outlet area of a basket.
- the width of the gap between the individual colander bars is determined by the thickness of the spacer ribs (gap dimension s).
- the exit space for the liquid phase also begins at the longitudinal edges of the surface of the strainer bars that come into contact with the pressed material and expands continuously according to the pitch angle for the bar shape. Blockages caused by fine particles carried in the pressed liquid are therefore significantly reduced compared to the conventional design.
- screw presses can fundamentally be redesigned, specifically with regard to screw geometry, strainer basket length, strainer basket diameter and press cake thickness.
- the ribs of a colander according to the invention do not necessarily have to be made of the same material as that of the colander, it is possible to produce the ribs on the colander using other suitable materials.
- strainer rods according to the invention can be assembled into such a strainer basket, in which the liquid exits radially outwards through the exit surfaces. In the same way, it is possible to move in the opposite direction, ie to form a strainer rod which allows the liquid to pass radially inwards.
- the strainer rod shown in the drawing generally bears the reference number 10 and is formed with an essentially rectangular cross section over its longitudinal extent.
- the areas with the substantially rectangular cross-section bear the reference numbers 11, they are located between areas with rib-shaped projections 22, which have the reference numbers 12 at the ends of the strainer rod 10 and the reference number 120 in the middle. With s the gap width is designated in the upper area of the strainer rod 10.
- the projections 22 are formed in accordance with the pitch angle ⁇ , and for clarity the center of a strainer basket is designated by M and the corresponding angle ⁇ is given.
- strainer rods 10 shown in the figure can be placed next to one another, so that the rods lie against one another on the rib surfaces 22 and can form a cylindrical strainer basket without further aids. Passage cross-sections, each with the width s, then result between the adjacent strainer bars 10.
- the surface of the strainer rod 10 pointing to the compression space is formed with an inclination, as is indicated by the angle ⁇ in the figure is recognizable.
- the angle ⁇ is only a few degrees, but it ensures that the exit cross-sectional areas are not formed by boundaries lying in a common plane, but that the exit cross-section between two adjacent strainer bars protrudes radially inwards with respect to the other. In this way, a significantly higher efficiency of the pressing process can be achieved.
- strainer bars had relatively wide radial extensions, and this was also absolutely necessary in view of the low tilt resistance of such strainer bars. With the help of the strainer bars according to the invention, it is possible to proceed to a considerably reduced extent in the circumferential direction.

Abstract
Description
Die Erfindung bezieht sich auf einen Seiherstab für einen aus einer Mehrzahl von Seiherstäben zusammengesetzten im wesentlichen zylinderförmigen Seiherkorb zwecks Eingrenzung eines Kompressionsraumes in einer Schneckenpresse für die Verarbeitung von tierischen bzw. pflanzlichen Produkten zu Fleischmehl und Tierfett bzw. pflanzlichen Ölen und dergl.The invention relates to a strainer rod for a substantially cylindrical strainer basket composed of a plurality of strainer rods for the purpose of delimiting a compression space in a screw press for the processing of animal or vegetable products into meat meal and animal fat or vegetable oils and the like.
Es ist bekannt, bei Ausrüstungen für die Verarbeitung von tierischen Abfällen, sowohl als auch pflanzlichen Produkten, zur Gewinnung von Fleischmehl und Tierfett bzw. pflanzlichen Ölen und dergl., Schneckenpressen zu verwenden. Hierzu werden Schnecken eingesetzt, deren Kerndurchmesser von der Zuführ- zur Austrittsöffnung hin ansteigt, wobei an der Außenoberfläche der Schnecke die Schneckenwindungen in unterschiedlichsten Ausführungsformen ausgebildet sein können und einen Kompressionsraum bilden. Der den Kompressionsraum umhüllende Seiherkorb bildet mit gelegten Seiherstäben die Siebfläche für die abzutrennende Flüssigkeit, wobei durch dünne Distanzblättchen zwischen den Seiherstäben die freien Austrittsflächen erzeugt werden. Die Seiherstäbe werden aus ihrer ursprünglichen rechteckigen Form - hochkant eingelegt - und sind in der Regel nach außen hin verjüngt ausgebildet, um der Flüssigkeit und den eventuell mitgeführten Feinstteilchen den Austritt zu ermöglichen.It is known to use screw presses in equipment for processing animal waste, both as well as vegetable products, for the production of meat meal and animal fat or vegetable oils and the like. Screws are used for this purpose, the core diameter of which increases from the feed opening to the outlet opening, the screw turns being able to be formed in the most varied of embodiments on the outer surface of the screw and forming a compression space. The strainer basket enveloping the compression space forms the sieve surface for the liquid to be separated with laid strainer rods, the free exit surfaces being generated by thin spacer plates between the strainer rods. The colander rods are inserted from their original rectangular shape - inserted upright - and are generally tapered towards the outside in order to allow the liquid and any fine particles that are carried along to exit.
Diese Konstruktion erfordert eine relativ dicke Ausführung der Seiherstäbe, damit eine breite Auflagefläche auf den Stützrippen gegen Wegkippen oder Verschieben gewährleistet wird. Außerdem ist die Querschnittsform zur geometrischen Form eines Kreisringsektors ausgebildet, so dass die natürlich zur Verfügung stehende Auflagefläche auf den Stützrippen des Seiherkorbes nicht vollflächig ausgenutzt werden kann.This construction requires a relatively thick design of the strainer rods, so that a wide contact surface on the support ribs guarantees against tipping or shifting becomes. In addition, the cross-sectional shape is formed to the geometric shape of a circular ring sector, so that the naturally available contact surface on the support ribs of the strainer basket cannot be used over the entire area.
Die Befestigung und somit die Verspannung der Seiherstäbe erfolgt durch Klemmleisten, die an der Trennfuge der Seiherkorbhälften verschraubt werden. Die Spannkraft hierzu verläuft mehr oder weniger linear oder punktförmig im Bereich der dem Innenraum zugewandten Zone der Stäbe und wird über die Distanzblättchen an der engsten Stelle zwischen diesen übertragen. Eine angeschliffene Längsfläche im Kopfbereich der Stäbe zur Übertragung der Spannkraft auf die Seiherstäbe über die Distanzblättchen kann den Flüssigkeits-/Feststoffaustritt behindern und zeitweise zu Verstopfungen zwischen den Stäben führen.The strainer rods are fastened and thus braced by means of clamping strips which are screwed to the parting line of the strainer basket halves. The clamping force for this is more or less linear or point-shaped in the area of the zone of the bars facing the interior and is transmitted via the spacer plates at the narrowest point between them. A sanded longitudinal surface in the head area of the rods for transferring the tension to the strainer rods via the spacer plates can prevent the liquid / solid from escaping and sometimes lead to blockages between the rods.
Die vorliegende Erfindung beschäftigt sich mit dem Problem, mit einer vergrößerten Austrittsfläche spürbare Vorteile (reduzierte Fett- bzw. Ölgehalte) im Pressgut zu erreichen und dabei auch noch die Montage von Seiherstäben im Seiherkorb wesentlich zu vereinfachen.The present invention deals with the problem of achieving noticeable advantages (reduced fat or oil contents) in the pressed material with an enlarged outlet area and at the same time also considerably simplifying the assembly of strainer rods in the strainer basket.
Erreicht wird dies durch die kennzeichnenden Merkmale der Ansprüche.This is achieved through the characterizing features of the claims.
Anstelle der bisher genutzten Distanzelemente werden nun die Seiherstäbe gemäß der Erfindung mit Distanzrippen durch Aufschweißungen oder Materialerhebungen versehen, die dem Teilungswinkel (Anzahl der erforderlichen Stäbe pro Korb bestimmt) angepaßt und entsprechend geformt sind.Instead of the previously used spacer elements, the strainer rods according to the invention are now provided with spacer ribs by welding or material elevations, which are adapted to the pitch angle (number of required rods per basket) and shaped accordingly.
Durch diese Form liegen die Seiherstäbe mit der ganzen Fläche der Rippen aneinander an und erfahren so einen stabilen Sitz im Seiherkorb, der eine Bewegung oder Wegkippen der Seiherstäbe zwischen den Klemmleisten unmöglich macht. Dadurch kann die Dicke der Seiherstäbe bedeutsam reduziert, entsprechend die Anzahl der Stäbe erhöht werden, was zu einer entsprechenden Erhöhung der wirksamen Flüssigkeitsaustrittsfläche eines Korbes führt.Due to this shape, the strainer rods lie against each other with the entire surface of the ribs and thus experience one stable seat in the strainer basket, which makes it impossible to move or tilt the strainer rods between the terminal strips. As a result, the thickness of the strainer rods can be significantly reduced and the number of rods increased accordingly, which leads to a corresponding increase in the effective liquid outlet area of a basket.
Die Breite der Spalte zwischen den einzelnen Seiherstäben wird durch die Dicke der Distanzrippen (Spaltmaß s) festgelegt. Der Austrittsraum für die Flüssigphase beginnt zugleich an den Längskanten der Fläche der Seiherstäbe, die mit dem Pressgut in Berührung kommt und expandiert kontinuierlich entsprechend dem Teilungswinkel für die Stabform. Verstopfungen durch mitgeführte Feinteile in der abgepressten Flüssigkeit werden daher bedeutsam gegenüber der herkömmlichen Ausführung reduziert.The width of the gap between the individual colander bars is determined by the thickness of the spacer ribs (gap dimension s). The exit space for the liquid phase also begins at the longitudinal edges of the surface of the strainer bars that come into contact with the pressed material and expands continuously according to the pitch angle for the bar shape. Blockages caused by fine particles carried in the pressed liquid are therefore significantly reduced compared to the conventional design.
Aus diesen Überlegungen resultiert, dass Schneckenpressen grundsätzlich neu konzipiert werden können, und zwar bezüglich der Schneckengeometrie, Seiherkorblänge, Seiherkorbdurchmesser und Preßkuchendicke.The result of these considerations is that screw presses can fundamentally be redesigned, specifically with regard to screw geometry, strainer basket length, strainer basket diameter and press cake thickness.
Die Rippen eines Seiherstabes gemäss der Erfindung müssen nicht notwendigerweise aus dem gleichen Material wie dem des Seiherstabes hergestellt werden, es besteht die Möglichkeit, die Rippen auch durch andere geeignete Materialien auf dem Seiherstab herzustellen.The ribs of a colander according to the invention do not necessarily have to be made of the same material as that of the colander, it is possible to produce the ribs on the colander using other suitable materials.
Die Seiherstäbe gemäss der Erfindung können zu einem solchen Seiherkorb zusammengesetzt werden, bei welchem die Flüssigkeit radial nach außen durch die Austrittsflächen hindurch austritt. In gleicher Weise ist es möglich, in umgekehrter Richtung zu verfahren, d.h. einen Seiherstab auszubilden, der einen Durchtritt der Flüssigkeit radial nach innen hin ermöglicht.The strainer rods according to the invention can be assembled into such a strainer basket, in which the liquid exits radially outwards through the exit surfaces. In the same way, it is possible to move in the opposite direction, ie to form a strainer rod which allows the liquid to pass radially inwards.
Die Erfindung wird nachstehend anhand der Zeichnung beispielsweise erläutert.The invention is explained below with reference to the drawing, for example.
Die einzige Figur der Zeichnung zeigt eine schaubildliche Ansicht eines Seiherstabes gemäß der Erfindung.The only figure in the drawing shows a perspective view of a strainer bar according to the invention.
Der in der Zeichnung gezeigte Seiherstab trägt allgemein die Bezugszahl 10 und ist über seine Längserstreckung mit einem im wesentlichen rechteckigen Querschnitt ausgebildet. Die Bereiche mit dem im wesentlichen rechteckförmigen Querschnitt tragen die Bezugsziffern 11, sie befinden sich zwischen Bereichen mit rippenförmigen Vorsprüngen 22, die an den Enden des Seiherstabs 10 die Bezugszahlen 12 und in der Mitte die Bezugszahl 120 tragen. Mit s ist im oberen Bereich des Seiherstabes 10 die Spaltbreite bezeichnet.The strainer rod shown in the drawing generally bears the reference number 10 and is formed with an essentially rectangular cross section over its longitudinal extent. The areas with the substantially rectangular cross-section bear the reference numbers 11, they are located between areas with rib-shaped projections 22, which have the reference numbers 12 at the ends of the strainer rod 10 and the reference number 120 in the middle. With s the gap width is designated in the upper area of the strainer rod 10.
Die Vorsprünge 22 werden dem Teilungswinkel α entsprechend ausgebildet, und zur Verdeutlichung ist der Mittelpunkt eines Seiherkorbes mit M bezeichnet und der entsprechende Winkel α angegeben.The projections 22 are formed in accordance with the pitch angle α, and for clarity the center of a strainer basket is designated by M and the corresponding angle α is given.
Es liegt auf der Hand, dass eine Mehrzahl der in der Figur gezeigten Seiherstäbe 10 aneinandergesetzt werden kann, so dass die Stäbe an den Rippenflächen 22 aneinanderliegen und ohne weitere Hilfsmittel einen zylindrischen Seiherkorb bilden können. Zwischen den benachbarten Seiherstäben 10 ergeben sich dann Durchtrittsquerschnitte mit jeweils der Breite s.It is obvious that a plurality of the strainer rods 10 shown in the figure can be placed next to one another, so that the rods lie against one another on the rib surfaces 22 and can form a cylindrical strainer basket without further aids. Passage cross-sections, each with the width s, then result between the adjacent strainer bars 10.
In Querrichtung, d.h. im eingebauten Zustand in Umfangsrichtung, ist die auf den Kompressionsraum hinweisende Fläche des Seiherstabes 10 mit einer Neigung ausgebildet, wie dies durch den Winkel β in der Figur zu erkennen ist. Der Winkel β beträgt nur wenige Grad, durch ihn wird jedoch erreicht, dass die Austrittsquerschnittsflächen nicht durch in einer gemeinsamen Ebene liegende Umgrenzungen gebildet werden, sondern dass die eine Begrenzung des Austrittsquerschnitts zwischen zwei benachbarten Seiherstäben radial nach Innen in Bezug auf die andere vorsteht. Auf diese Art und Weise kann ein deutlich höherer Wirkungsgrad des Preßvorganges erzielt werden.In the transverse direction, ie in the installed state in the circumferential direction, the surface of the strainer rod 10 pointing to the compression space is formed with an inclination, as is indicated by the angle β in the figure is recognizable. The angle β is only a few degrees, but it ensures that the exit cross-sectional areas are not formed by boundaries lying in a common plane, but that the exit cross-section between two adjacent strainer bars protrudes radially inwards with respect to the other. In this way, a significantly higher efficiency of the pressing process can be achieved.
Bisher hatten Seiherstäbe relativ breite Radialerstreckungen, und dies war im Hinblick auf die geringe Kippfestigkeit derartiger Seiherstäbe auch unbedingt erforderlich. Mit Hilfe der Seiherstäbe gemäss der Erfindung kann auf eine erheblich reduzierte Erstreckung in Umfangsrichtung übergegangen werden.Previously, strainer bars had relatively wide radial extensions, and this was also absolutely necessary in view of the low tilt resistance of such strainer bars. With the help of the strainer bars according to the invention, it is possible to proceed to a considerably reduced extent in the circumferential direction.
