Abstract
A partial stream of the suspension fed into the rising channels (5) via the feed pipe (19) and the inlet chamber (7) is continuously drawn off via the outlet apertures (8), the channel sections (12) and the skimmer (15). At very high concentrations of the solid phase extracted via the outlet channels (3), the solid particles collecting in the solid chamber (2) reach the rising channels (5). These solid particles are conducted out of the plate insert (4) by the partial stream so that the degree of clarity of the plate set is not affected by these solid particles. It is thus possible with the centrifugal drum (1) to obtain very high solid concentrations without adversely affecting the clarified suspension.
Description
Schleudertrommel zur Konzentrierung suspendierter Fest¬ stoffeCentrifugal drum for the concentration of suspended solids
Die Erfindung betrifft eine Schleudertrommel zur Konzen- trierung suspendierter Feststoffe mit einem peripheren, mit Ablaßkanälen versehenen Feststoffraum und einem Tel¬ lereinsatz mit Steigekanälen, deren Eintrittsöffnungen mit einem Einlaufräum der Schleudertrommel verbunden sind, dem die zu klärende Suspension zugeführt wird, wobei im Zen- trum des Tellereinsatzes Kanäle zur Ableitung der geklär¬ ten Suspension vorgesehen sind und der Tellereinsatz an seiner Peripherie mit dem Feststoffraum in Verbindung steht, wodurch die im Tellereinsatz abgeschiedenen Fest¬ stoffe in den Feststoffräum geleitet werden.The invention relates to a centrifugal drum for concentrating suspended solids with a peripheral solid space provided with discharge channels and a telescopic insert with risers, the inlet openings of which are connected to an inlet space of the centrifugal drum, to which the suspension to be clarified is fed, in the center Channels of the plate insert are provided for discharging the clarified suspension and the plate insert is connected at its periphery to the solid space, whereby the solids separated in the plate insert are guided into the solid space.
Eine derartige Schleudertrommel ist beispielsweise aus der DE 33 20 152 AI bekannt. Die abgeschiedenen Feststoffe sammeln sich im Feststoffraum dieser Schleudertrommel und werden durch die Ablaßkanäle kontinuierlich ausgetragen. Um eine hohe Feststoffkonzentration zu erzielen, ist der Querschnitt der Ablaßkanäle so zu bemessen, daß möglichst wenig Flüssigkeit mit den Feststoffen ausgetragen wird. Mit zunehmender Feststoffkonzentration wächst allerdings auch die sich im Feststoffraum ausbildende Feststoff- schicht radial einwärts bis schließlich Feststoffe auch in die Steigekanäle gelangen und mit der radial einwärts strömenden geklärten Suspension ausgetragen werden. Da-
durch wird dann der Klärgrad der Suspension in unerwünsch¬ ter Weise beeinträchtigt. Es ist also ein Kompromiß erfor¬ derlich zwischen der maximalen Konzentration der Feststof¬ fe und dem optimalen Klärgrad der Suspension.Such a centrifugal drum is known for example from DE 33 20 152 AI. The separated solids collect in the solids chamber of this centrifugal drum and are continuously discharged through the discharge channels. In order to achieve a high solids concentration, the cross-section of the discharge channels must be dimensioned so that as little liquid as possible is discharged with the solids. With increasing solids concentration, however, the solids layer forming in the solids space also grows radially inward until finally solids also get into the riser channels and are discharged with the clarified suspension flowing radially inwards. There- then the degree of clarification of the suspension is adversely affected. A compromise is therefore necessary between the maximum concentration of the solids and the optimum degree of clarification of the suspension.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, die Schleudertrommel so auszubilden, daß der Klärgrad der Sus¬ pension von der Konzentration der Feststoffe weitgehend unbeeinflußt bleibt.The object of the present invention is to design the centrifugal drum so that the degree of clarification of the suspension remains largely unaffected by the concentration of the solids.
Diese Aufgabe wird dadurch gelöst, daß die Steigekanäle mit Austrittsöffnungen versehen sind, die über Verbin¬ dungskanäle mit dem Feststoffraum in Verbindung stehen, wobei die Verbindungskanäle radial einwärts gerichtete, mit Auslaßöffnungen versehene Kanalabschnitte zur separa¬ ten Ableitung eines feststoffhaltigen Teilstromes beinhal¬ ten.This object is achieved in that the riser channels are provided with outlet openings which are connected to the solids space via connecting channels, the connecting channels comprising radially inwardly directed channel sections provided with outlet openings for separate discharge of a partial stream containing solids.
Es hat sich überraschend gezeigt, daß durch die Ableitung eines separaten feststoffhaltigen Teilstromes aus den Aus¬ trittsöffnungen der Steigekanäle über die radial einwärts gerichteten Kanalabschnitte ein Feststofftransport zum Zentrum des Tellereinsatzes mit der damit verbundenen Be¬ einträchtigung des Klärgrades der Suspension vermieden wird. Ein Teil der im Teilstrom befindlichen Feststoffe wird dabei in den Verbindungskanälen abgeschieden und wie¬ der in den Feststoffräum zurückgeführt.
Bei einer weiteren vorteilhaften Ausgestaltung sind die Verbindungskanäle als Klärspalte ausgebildet. Die Klär¬ spalte unterstützen die Abscheidung der Feststoffpartikel, die an der radial äußeren Wandung des Klärspaltes in den Feststoffräum gleiten.It has surprisingly been found that by diverting a separate partial stream containing solids from the outlet openings of the riser channels via the radially inwardly directed channel sections, solids transport to the center of the plate insert, with the associated impairment of the degree of clarification of the suspension, is avoided. Some of the solids in the partial flow are separated off in the connecting channels and returned to the solids space. In a further advantageous embodiment, the connecting channels are designed as clarifying gaps. The clarification gaps support the separation of the solid particles that slide into the solid space on the radially outer wall of the clarification gap.
Der Klärspalt wird auf vorteilhafte Weise gebildet zwi¬ schen einer konischen Innenwand der Schleudertrommel und einer konzentrisch dazu angeordneten, mit Abstandsleisten versehenen Außenwand eines Zwischentellers. Durch diese Lösung werden besonders großzügige Absetzflächen für den Feststoff im Klärspalt zur Verfügung gestellt, die durch im Klärspalt vorgesehene Teller noch vergrößert werden können.The clarifying gap is advantageously formed between a conical inner wall of the centrifugal drum and an outer wall of an intermediate plate arranged concentrically therewith and provided with spacer strips. This solution provides particularly large sedimentation areas for the solids in the clarification gap, which can be further enlarged by plates provided in the clarification gap.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachstehend näher erläutert.An embodiment of the invention is shown in the drawing and is explained in more detail below.
Mit 1 ist in der Fig. die Schleudertrommel bezeichnet, von deren Feststoffräum 2 Ablaßkanäle 3 ausgehen. Die Schleu¬ dertrommel 1 ist mit einem Tellereinsatz 4 ausgerüstet, dessen Steigekanäle 5 über ihre Eintrittsöffnungen 6 mit einem Einlaufräum 7 verbunden sind. An dem den Eintritts¬ öffnungen 6 gegenüberliegenden Ende der Steigekanäle 5 sind Austrittsöffnungen 8 vorgesehen, die über Verbin¬ dungskanäle 9 mit dem Feststoffräum 2 verbunden sind. Die Verbindungskanäle 9 werden gebildet zwischen einer Innen-
wand der Schleudertrommel 1 und einer konzentrisch dazu angeordneten, mit Abstandsleisten 10 versehenen Außenwand eines Zwischentellers 11 und besitzen radial einwärts ge¬ richtete Kanalabschnitte 12, deren Auslaßöffnungen 13 in eine Schälkammer 14 münden, in der ein Schälorgan 15 vor¬ gesehen ist. Während die Peripherie des Tellereinsatzes 4 mit dem Feststoffräum 2 in Verbindung steht, ist das Zen¬ trum des Tellereinsatzes 4 über Kanäle 16 mit einer Schäl¬ kammer 17 verbunden, in der ein Schälorgan 18 angeordnet ist. In den Einlaufräum 7 mündet ein Zulaufröhr 19. Zwi¬ schen der Innenwand der Schleudertrommel 1 und der Außen¬ wand des Zwischentellers 11 sind Teller 20 vorgesehen. Die Verbindungskanäle 9 sind über Kanäle 21 mit dem Einlauf¬ raum 7 verbunden.1 in the figure is the centrifugal drum, from whose solid space 2 discharge channels 3 extend. The centrifugal drum 1 is equipped with a plate insert 4, the riser channels 5 of which are connected to an inlet space 7 via their inlet openings 6. At the end of the rising channels 5 opposite the inlet openings 6, outlet openings 8 are provided which are connected to the solid space 2 via connecting channels 9. The connecting channels 9 are formed between an interior wall of the centrifugal drum 1 and an concentrically arranged, provided with spacer strips 10 outer wall of an intermediate plate 11 and have radially inwardly directed channel sections 12, the outlet openings 13 opening into a peeling chamber 14, in which a peeling member 15 is provided. While the periphery of the plate insert 4 is connected to the solid space 2, the center of the plate insert 4 is connected via channels 16 to a peeling chamber 17 in which a peeling member 18 is arranged. An inlet pipe 19 opens into the inlet space 7. Plates 20 are provided between the inner wall of the centrifugal drum 1 and the outer wall of the intermediate plate 11. The connecting channels 9 are connected to the inlet space 7 via channels 21.
Die feststoffhaltige Suspension wird über das Zulaufrohr 19 in den Einlaufraum 7 eingespeist und gelangt über die Eintrittsöffnungen 6 in die Steigekanäle 5 des Tellerein¬ satzes 4, in dem eine Abtrennung der Feststoffpartikel er- folgt. Die geklärte Suspension strömt zum Zentrum des Tel¬ lereinsatzes 4 und wird über die Kanäle 16, die Schälkam¬ mer 17 und das Schälorgan 18 aus der Schleudertrommel 1 abgeleitet. Die abgetrennten Feststoffpartikel gelangen über die Peripherie des Tellereinsatzes 4 zunächst in den Feststoffräum 2, bevor sie über die Ablaßkanäle 3 ausge¬ tragen werden. Der Querschnitt der Ablaßkanäle 3 muß zur Erzielung einer hohen Feststoffkonzentration so bemessen
sein, daß möglichst wenig Flüssigkeit mit den Feststoffen abgelassen wird. Je höher die eingestellten Konzentrati¬ onswerte sind, desto weiter füllt sich der Feststoffräum 2 radial einwärts. Bei sehr hohen Konzentrationswerten rei- chen die Feststoffpartikel bis in die Steigekanäle 5 hin¬ ein.The solid-containing suspension is fed into the inlet space 7 via the inlet pipe 19 and reaches the riser channels 5 of the plate insert 4 via the inlet openings 6, in which the solid particles are separated off. The clarified suspension flows to the center of the insert 4 and is discharged from the centrifugal drum 1 via the channels 16, the peeling chamber 17 and the peeling member 18. The separated solid particles first reach the solid space 2 via the periphery of the plate insert 4 before they are discharged via the discharge channels 3. The cross section of the discharge channels 3 must be dimensioned in this way in order to achieve a high solids concentration be that as little liquid as possible is drained off with the solids. The higher the concentration values set, the further the solid space 2 fills radially inwards. At very high concentration values, the solid particles reach into the rising channels 5.
Durch einen ständig über den Kanalabschnitt 12 abgezogenen Teilstrom der in die Steigekanäle 5 eingespeisten Suspen¬ sion werden diese Feststoffpartikel aus dem Tellereinsatz 4 herausgeführt. Ein Teil der Feststoffe wird in den als Klärspalte ausgebildeten, mit Tellern 20 versehenen Ver¬ bindungskanälen 9 abgeschieden und in den Feststoffraum 2 zurückgeführt. Die restlichen Feststoffe werden mit dem Teilstrom über das Schälorgan 15 aus der Trommel 1 abgezogen. Dadurch wird ein Klassiereffekt erreicht, durch den Feststoffar¬ ten, die im Feststoffkonzentrat nicht erwünscht sind, se¬ parat abgeführt werden können. Dies ist z. B. der Fall, bei der Konzentrierung von faserhaltigen Stärkesuspensio- nen, bei denen die Fasern im Stärkekonzentrat nicht er¬ wünscht sind.These solid particles are led out of the plate insert 4 by means of a partial flow of the suspension fed into the riser channels 5, which is continuously drawn off via the channel section 12. Some of the solids are separated in the connecting channels 9, which are designed as clarifying gaps and provided with plates 20, and are returned to the solids space 2. The remaining solids are withdrawn with the partial flow from the drum 1 via the peeling member 15. A classification effect is thereby achieved by means of which types of solids which are not desired in the solids concentrate can be removed separately. This is e.g. B. the case in the concentration of fiber-containing starch suspensions in which the fibers in the starch concentrate are not desired.
Mit der Schleudertrommel 1 können somit sehr hohe Fest¬ stoffkonzentrationen erzielt werden, ohne die geklärte Suspension zu beeinträchtigen bei gleichzeitiger getrenn- ter Abführung einer zweiten Feststoffart, die im Konzen¬ trat nicht erwünscht ist. Bei der Verarbeitung von Produkten, die zur Schaumbildung
neigen, kann dadurch verursachter Überlauf aus dem Ein¬ laufraum 7 über die Kanäle 21 und die Verbindungskanäle 9 in die Schälkammer 14 entweichen. Eine Beeinträchtigung der über das Schälorgan 18 abgeleiteten geklärten Phase wird dadurch vermieden.
Very high solids concentrations can thus be achieved with the centrifugal drum 1 without adversely affecting the clarified suspension while simultaneously removing a second type of solids, which is not desired in the concentrate. When processing products that cause foaming overflow caused thereby can escape from the inlet space 7 via the channels 21 and the connecting channels 9 into the peeling chamber 14. An impairment of the clarified phase derived via the peeling member 18 is thereby avoided.
