Definitions
- the invention relates to a loop mixer for mixing a product containing solids, in particular fibers, with a cylindrical mixer housing which has an inlet and an outlet for the product and in which a mixing loop is formed with a cylindrical guide tube, in which the product from the inside of the Guide tube is deflected via a radial opening in front of a front end of the guide tube into an annular cylindrical outer space of the guide tube and is returned there in countercurrent and from which the product reaches the outlet by means of guide devices which are arranged on the outside of the guide tube and cross the radial opening to the outlet, for transporting the Product a rotating displacer is arranged inside the guide tube.
- Loop mixers of this type are known as the applicant's "dynamic loop mixer” and have been used for many years. They offer the advantage that the mixing process can be carried out without dead space and a uniform mean throughput time for the product - and thus even mixing - through the accountings, which have a downstream inlet opening in the outside space and transport the mixed product to the regular outlet side opposite the inlet side, the guiding devices being required in order to transport the product at the radial opening and regardless of the product flow through the radial opening to the outlet. Accordingly, product flows around the guide devices in the region of the radial opening within the mixing loop. If the product contains solids, in particular fibers, these tend to accumulate on the outside of the guide devices and thus reduce the radial opening or have them completely clogged.
- a loop mixer of the type mentioned at the outset is characterized in that, in the region of the radial opening, a rotating scraper tool is arranged radially in front of the guide devices, said tool having a radial wall with at least one wall section is provided, which is closed by an inclined edge so that the height of the wall changes.
- the problem of clogging the loop mixer can thus be solved with the aid of a simple rotating tool which is designed in the form of a cylindrical wall and with the inclined edge of the at least one wall section presses the accumulated solids, in particular fibers, away from the guide devices so that the solids, in particular fibers, are grasped and taken away by the product stream flowing through the free cross section of the radial opening, that is to say they remain properly in the product circulating in the mixing loop.
- the cleaning intervals for the loop mixer could be extended from a few hours to several days, that is to say normal cleaning intervals for loop mixers for non-clogging products, with a stripping tool designed and arranged according to the invention.
- the wall section is triangular, a sawtooth shape, ie a triangle with a long flat slope and a short steep slope, is particularly preferred.
- the maximum height of the wall section corresponds approximately to the greatest height of the radial opening.
- the radial wall of the stripping tool is provided with two wall sections.
- the scraper tool with the at least one wall section is cup-shaped with a bottom, the bottom of the scraper tool being arranged as a front end of the guide tube.
- the speed of rotation of the rotating stripping tool is not critical.
- the stripping tool can therefore have a common drive with the rotating displacer in a simple manner.
- the rotating displacer is expediently a screw conveyor, so that the stripping tool is preferably attached to the drive shaft of the screw conveyor.
- the inner wall of the guide tube has axially extended shoulders preventing the product from rotating with the displacer.
- the inner wall can be formed from cylindrical wall sections arranged eccentrically to one another, between which the shoulders are formed.
- FIG. 1 shows a mixer housing 1 which is essentially cylindrical and has an inlet 2 for the product to be mixed on one end face and an outlet 3 for the mixed product on the other end face.
- a guide tube 4 Coaxial with the mixer housing 1 there is a guide tube 4, the length of which is shorter than the length of the mixer housing 1 in the cylindrical part, so that radial through openings 5, 6 are formed at both ends of the guide tube 4, through which the product from inside the Guide tube 4 in an annular cylindrical outer space 7 formed between guide tube 4 and mixer housing 1 and vice versa.
- a rotating drive shaft 8 of a screw conveyor 9 is arranged in the axis of symmetry of the guide tube 4.
- the amount of processed product exiting through outlet 3 corresponds to the amount of product pressed into the mixer through inlet 2.
- Arrows P illustrate the product circulation in the mixing loop formed by the inner space and the annular cylindrical outer space 7 of the guide tube 4, as well as the supply of the product through the inlet 2 and the outlet of the product through the pipe sections 10 into the outlet 3.
- a rotating scraper tool 13 is arranged according to the invention, which is cup-shaped with a bottom 14 and a radial wall 15.
- the radial wall 15 rotates immediately in front of the radially inner end of the pipe sections 10, which are arranged on a common radius and serve as guide devices.
- the bottom 14 forms a front end in the extension of the guide pipe 4 and at a distance from its end edge 16 on the output side.
- the radial wall 15 is formed with two wall sections 17 which are provided with an inclined edge 18.
- the inclined edge 18 leads from a small height H1 to a larger height H2.
- a steeper inclined edge 19 leads back to the original height H1.
- the stripping tool 13 is connected to the rotary shaft 8, that is to say rotates together with the screw conveyor 9. Due to the direction of rotation R, the product is pressed away laterally from the pipe sections 10 with the aid of the inclined edge 18. Solids contained in the product are therefore conveyed into the free area between the pipe pieces 10 and pass through the free area of the radial opening 5 with the product stream generated by the screw conveyor 9 into the ring-cylindrical outer space 7.
- Figure 3 illustrates that the guide tube 4 has a not uniformly cylindrical inner wall 20, but that the inner wall 20 consists of four cylindrical sections 21 which are arranged eccentrically to one another and therefore form axially aligned shoulders 22.
- This arrangement on the one hand prevents material from rotating with the rotation in the direction R of the screw conveyor 9, which would prevent the desired transport effect in the axial direction, on the other hand clogging of any grooves, circular openings or the like is prevented. avoided.
- FIG. 4 illustrates in another embodiment of the wall of the guide tube 4 that the outer wall can also be graduated in accordance with the design of the inner wall 20 if this appears expedient for manufacturing reasons.

Abstract
Description
Die Erfindung betrifft einen Schlaufenmischer zur Mischung eines Feststoffe, insbesondere Fasern, enthaltenden Produktes mit einem zylindrischen Mischergehäuse, das einen Einlaß und einen Auslaß für das Produkt aufweist und in dem mit einem zylindrischen Leitrohr eine Mischschlaufe ausgebildet ist, in der das Produkt aus dem Inneren des Leitrohres über eine radiale Öffnung vor einem stirnseitigen Abschluß des Leitrohres in einen ringzylindrischen Außenraum des Leitrohres umgelenkt und dort im Gegenstrom zurücktransportiert wird und aus der das Produkt mittels an der Außenseite des Leitrohres angeordnete, die radiale Öffnung querenden Leiteinrichtungen zum Auslaß gelangt, wobei zum Transport des Produktes ein rotierender Verdränger im Innern des Leitrohres angeordnet ist.The invention relates to a loop mixer for mixing a product containing solids, in particular fibers, with a cylindrical mixer housing which has an inlet and an outlet for the product and in which a mixing loop is formed with a cylindrical guide tube, in which the product from the inside of the Guide tube is deflected via a radial opening in front of a front end of the guide tube into an annular cylindrical outer space of the guide tube and is returned there in countercurrent and from which the product reaches the outlet by means of guide devices which are arranged on the outside of the guide tube and cross the radial opening to the outlet, for transporting the Product a rotating displacer is arranged inside the guide tube.
Derartige Schlaufenmischer sind als "dynamische Schlaufenmischer" der Anmelderin bekannt und werden seit vielen Jahren verwendet. Sie bieten den Vorteil, daß der Mischvorgang totraumfrei erfolgen kann und eine gleichmäßige mittlere Durchlaufzeit für das Produkt - und somit eine gleichmäßige Durchmischung - durch die kontungen, die im Außenraum eine stromabwärts gerichtete Eintrittsöffnung aufweisen und das gemischte Produkt zum regelmäßig auf der der Einlaßseite gegenüberliegenden stirnseitigen Auslaßseite transportieren, wobei die Leiteinrichtungen erforderlich sind, um das Produkt an der radialen Öffnung und unabhängig von der Produktströmung durch die radiale Öffnung zum Auslaß zu transportieren. Demgemäß werden die Leiteinrichtungen im Bereich der radialen Öffnung von Produkt innerhalb der Mischschlaufe umströmt. Enthält das Produkt Feststoffe, insbesondere Fasern, neigen diese dazu, sich an den Außenseiten der Leiteinrichtungen anzusammeln und so die radiale Öffnung zu verkleinern bzw. vollständig verstopfen zu lassen.Loop mixers of this type are known as the applicant's "dynamic loop mixer" and have been used for many years. They offer the advantage that the mixing process can be carried out without dead space and a uniform mean throughput time for the product - and thus even mixing - through the accountings, which have a downstream inlet opening in the outside space and transport the mixed product to the regular outlet side opposite the inlet side, the guiding devices being required in order to transport the product at the radial opening and regardless of the product flow through the radial opening to the outlet. Accordingly, product flows around the guide devices in the region of the radial opening within the mixing loop. If the product contains solids, in particular fibers, these tend to accumulate on the outside of the guide devices and thus reduce the radial opening or have them completely clogged.
Für besonders kritische faserhaltige Produkte muß nach einer Laufzeit von wenigen Stunden eine Reinigung vorgenommen werden. Hierdurch wird die Effizienz des Einsatzes des Schlaufenmischers herabgesetzt, da insbesondere bei der Verarbeitung von Lebensmitteln nach der Reinigung ein keimfreier Zustand im Schlaufenmischer wieder hergestellt werden muß.For particularly critical fiber-containing products, cleaning must be carried out after a period of a few hours. As a result, the efficiency of the use of the loop mixer is reduced, since a germ-free state in the loop mixer must be restored in particular when processing food after cleaning.
Ausgehend von der Problemstellung, die Effizienz eines derartigen Schlaufenmischers zu erhöhen, ist ein Schlaufenmischer der eingangs erwähnten Art erfindungsgemäß dadurch gekennzeichnet, daß im Bereich der radialen Öffnung radial innen vor den Leiteinrichtungen ein rotierendes Abstreifwerkzeug angeordnet ist, das mit einer radialen Wand mit wenigstens einem Wandabschnitt versehen ist, der durch eine schräge Kante so abgeschlossen ist, daß sich die Höhe der Wand ändert.Starting from the problem of increasing the efficiency of such a loop mixer, a loop mixer of the type mentioned at the outset is characterized in that, in the region of the radial opening, a rotating scraper tool is arranged radially in front of the guide devices, said tool having a radial wall with at least one wall section is provided, which is closed by an inclined edge so that the height of the wall changes.
Erfindungsgemäß läßt sich das Problem des Zusetzens des Schlaufenmischers somit mit Hilfe eines einfachen rotierenden Werkzeuges lösen, das in Form einer zylindrischen Wand ausgebildet ist und mit der schrägen Kante des wenigstens einen Wandabschnittes die angesammelten Feststoffe, insbesondere Fasern, seitlich von den Leiteinrichtungen wegdrückt, so daß die Feststoffe, insbesondere Fasern, vom durch den freien Querschnitt der radialen Öffnung strömenden Produktstrom erfaßt und mitgenommen werden, also ordnungsgemäß in dem in der Mischschlaufe umlaufenden Produkt verbleiben.According to the invention, the problem of clogging the loop mixer can thus be solved with the aid of a simple rotating tool which is designed in the form of a cylindrical wall and with the inclined edge of the at least one wall section presses the accumulated solids, in particular fibers, away from the guide devices so that the solids, in particular fibers, are grasped and taken away by the product stream flowing through the free cross section of the radial opening, that is to say they remain properly in the product circulating in the mixing loop.
Es hat sich gezeigt, daß mit einem erfindungsgemäß ausgebildeten und angeordneten Abstreifwerkzeug die Reinigungsintervalle für den Schlaufenmischer von wenigen Stunden auf mehrere Tage, also auf normale Reinigungsintervalle für Schlaufenmischer für nicht verstopfende Produkte, verlängert werden konnte.It has been shown that the cleaning intervals for the loop mixer could be extended from a few hours to several days, that is to say normal cleaning intervals for loop mixers for non-clogging products, with a stripping tool designed and arranged according to the invention.
In einer bevorzugten Ausführungsform ist der Wandabschnitt dreieckförmig ausgebildet, wobei eine Sägezahnform, also ein Dreieck mit einer langen flachen Schräge und einer kurzen steilen Schräge, besonders bevorzugt ist.In a preferred embodiment, the wall section is triangular, a sawtooth shape, ie a triangle with a long flat slope and a short steep slope, is particularly preferred.
Zweckmäßig ist es, wenn die maximale Höhe des Wandabschnittes etwa der größten Höhe der radialen Öffnung entspricht.It is expedient if the maximum height of the wall section corresponds approximately to the greatest height of the radial opening.
In einer in der praktischen Erprobung bewährten Ausführungsform ist die radiale Wand des Abstreifwerkzeuges mit zwei Wandabschnitten versehen.In an embodiment that has proven itself in practical testing, the radial wall of the stripping tool is provided with two wall sections.
In einer konstruktiv sehr zweckmäßigen Ausführungsform ist das Abstreifwerkzeug mit dem wenigstens einem Wandabschnitt topfförmig mit einem Boden ausgebildet, wobei der Boden des Abstreifwerkzeuges als stirnseitiger Abschluß des Leitrohres angeordnet ist.In a structurally very expedient embodiment, the scraper tool with the at least one wall section is cup-shaped with a bottom, the bottom of the scraper tool being arranged as a front end of the guide tube.
Die Umdrehungsgeschwindigkeit des rotierenden Abstreifwerkzeuges ist nicht kritisch. Das Abstreifwerkzeug kann daher in einfacher Weise einen gemeinsamen Antrieb mit dem rotierenden Verdränger aufweisen.The speed of rotation of the rotating stripping tool is not critical. The stripping tool can therefore have a common drive with the rotating displacer in a simple manner.
Der rotierende Verdränger ist zweckmäßigerweise eine Förderschnecke, so daß das Abstreifwerkzeug vorzugsweise an der Antriebswelle der Förderschnecke befestigt ist.The rotating displacer is expediently a screw conveyor, so that the stripping tool is preferably attached to the drive shaft of the screw conveyor.
Da das Produkt ab einer bestimmten Viskosität dazu neigt, sich mit dem rotierenden Verdränger mitzudrehen und somit nicht mehr vorgefördert zu werden, ist es zweckmäßig, wenn die Innenwandung des Leitrohres ein Mitdrehen des Produktes mit dem Verdränger verhindernde axial erstreckte Absätze aufweist. Hierzu kann die Innenwandung aus zueinander exzentrisch angeordneten zylindrischen Wandabschnitten gebildet sein, zwischen denen die Absätze ausgebildet sind.Since the product tends to rotate with the rotating displacer from a certain viscosity and is therefore no longer conveyed forward, it is expedient if the inner wall of the guide tube has axially extended shoulders preventing the product from rotating with the displacer. For this purpose, the inner wall can be formed from cylindrical wall sections arranged eccentrically to one another, between which the shoulders are formed.

Figur 1 läßt ein Mischergehäuse 1 erkennen, das im wesentlichen zylindrisch ausgebildet ist und auf einer Stirnseite einen Einlaß 2 für das zu mischende Produkt und auf der anderen Stirnseite einen Auslaß 3 für das gemischte Produkt aufweist.FIG. 1 shows a
Koaxial mit dem Mischergehäuse 1 befindet sich in diesem ein Leitrohr 4, dessen Länge kürzer ist als die Länge des Mischergehäuses 1 im zylindrischen Teil, so daß radiale Durchtrittsöffnungen 5, 6 an beiden Enden des Leitrohres 4 entstehen, durch die das Produkt aus dem Innern des Leitrohres 4 in einen zwischen Leitrohr 4 und Mischergehäuse 1 gebildeten ringzylindrischen Außenraum 7 und umgekehrt gelangen kann.Coaxial with the mixer housing 1 there is a
In der Symmetrieachse des Leitrohres 4 ist eine rotierende Antriebswelle 8 einer Förderschnecke 9 angeordnet. Die das Leitrohr 4 im wesentlichen ausfüllende Förderschnecke 9 transportiert das Produkt vom eingangsseitigen Ende des Leitrohres 4 zum ausgangsseitigen Ende, wo das Produkt in den ringzylindrischen Außenraum 7 umgelenkt und im Gegenstrom zum eingangsseitigen Ende des Leitrohres zurückgefördert wird, um sich dann mit dem durch den Einlaß 2 eingetretenen neuen Produkt zu vermischen.A rotating drive shaft 8 of a
Am ausgangsseitigen Ende des Leitrohres 4 sind an diesem vier gleichmäßig über dessen Umfang verteilte Rohrstücke 10 angeordnet, die in einen gemeinsamen Auslaßraum 11 münden, der sich konisch zum Anschlußflansch 12 des Auslasses 3 verjüngt.At the outlet-side end of the
Die durch den Auslaß 3 austretende, bearbeitete Produktmenge entspricht der durch den Einlaß 2 in den Mischer eingedrückten Produktmenge. Pfeile P verdeutlichen den Produktumlauf in der durch den Innenraum und den ringzylindrischen Außenraum 7 des Leitrohres 4 gebildeten Mischschlaufe sowie die Zuführung des Produktes durch den Einlaß 2 und den Austritt von Produkt durch die Rohrstücke 10 in den Auslaß 3.The amount of processed product exiting through
Im Bereich der radialen Durchgangsöffnung 5 ist erfindungsgemäß ein rotierendes Abstreifwerkzeug 13 angeordnet, das topfförmig mit einem Boden 14 und einer radialen Wand 15 ausgebildet ist. Die radiale Wand 15 rotiert dabei unmittelbar vor dem radial inneren Ende der auf einem gemeinsamen Radius angeordneten, als Leiteinrichtungen dienenden Rohrstücke 10. Der Boden 14 bildet einen stirnseitigen Abschluß in Verlängerung des Leitrohres 4 und mit Abstand von dessen ausgangsseitiger Endkante 16.In the area of the radial through opening 5, a rotating

Wie insbesondere die in Figur 2 dargestellte Abwicklung verdeutlicht, führt die schräge Kante 18 von einer geringen Höhe H1 zu einer größeren Höhe H2.

Wie Figur 1 verdeutlicht, ist das Abstreifwerkzeug 13 mit der Rotationswelle 8 verbunden, rotiert also zusammen mit der Förderschnecke 9. Aufgrund der Rotationsrichtung R wird das Produkt mit Hilfe der schrägen Kante 18 seitlich von den Rohrstücken 10 weggedrückt. In dem Produkt enthaltene Feststoffe werden daher in den freien Bereich zwischen den Rohrstücken 10 gefördert und gelangen durch den freien Bereich der radialen Öffnung 5 mit dem von der Förderschnecke 9 erzeugten Produktstrom in den ringzylindrischen Außenraum 7.As illustrated in FIG. 1, the

Durch diese Anordnung wird einerseits verhindert, daß sich Material mit der Rotation in Richtung R der Förderschnecke 9 mitdreht, was den angestrebten Transporteffekt in axialer Richtung unterbinden würde, andererseits wird ein Zusetzen von etwaigen Nuten, kreisförmigen Öffnungen o.ä. vermieden.Figure 3 illustrates that the
