Abstract

In order to improve the separating result in horizontal separators and in particular in order to achieve a high degree of selectivity with large processing loads and a small separation path, in a process for separating heterogeneous material, in particular for presorting refuse, which has been precleaned of fine materials, in a gas stream which is directed essentially horizontally, into which gas stream the material is dropped from above, the individual material components - depending on their weight and size - describe different flight paths and are separated in this way, it is proposed that the material components entering the gas stream (separation zone 3) from above have reached at least half the value of the free falling speed corresponding to their size and density. This method can be used in a device of the type of a horizontal cross-current separator having an essentially horizontally arranged housing (19) at whose one end an inlet opening for the separating gas stream which is generated by a blower (1) and enters essentially horizontally is mounted and which housing also has in the upper region a filling opening (25) for the material to be separated and which has in the lower region a plurality of discharge openings (26, 28), arranged behind one another in the direction of the separating gas stream and downstream of the filling opening (25), for the individual material components which are deflected different distances, a fall shaft (21) being present above the filling opening (25), which shaft is of such a length that the material components have reached a speed as given above when passing through the filling opening (25) or that instead of the fall shaft (21) a relatively short input shaft (20) is provided into which an acceleration device for the material components, e.g. a cellular wheel sluice (23) is installed. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zum Sichten von grobkörnigem Gut nach dem Oberbegriff des Anspruchs 1 (vgl. DE-OS 25 35 881). Bei den bekannten Querstromsichtverfahren dieser Art tritt das zu sichtende Gut mit einer Geschwindigkeit ein, die sich aus der Aufgabe über einen Fülltrichter unmittelbar über der Sichtzone ergibt (vgl. Fig. der genannten Offenlegungsschrift). Das Gut tritt hierbei in einer hohen Gutkonzentration, die noch keinerlei Vorsichtung erlaubt, in die Sichtzone ein.The invention relates to a method for classifying coarse-grained material according to the preamble of claim 1 (cf. DE-OS 25 35 881). In the known cross-flow sighting methods of this type, the material to be sifted occurs at a speed which results from the task of filling a funnel directly above the viewing zone (cf. FIG. Of the aforementioned publication). The material enters the viewing zone in a high material concentration that still does not allow any precaution.

Der Erfindung liegt die Aufgabe zugrunde, bei diesem Horizontalquerstromsichten das Sichtergebnis zu verbessern, insbesondere bei großen Aufgabemengen und kleinem Sichtweg eine hohe Trennschärfe zu erreichen.The object of the invention is to improve the viewing result with these horizontal cross-flow views, in particular to achieve a high degree of selectivity with large feed quantities and a small line of sight.

Gelöst wird diese Aufgabe mit der Maßnahme nach dem Kennzeichen des Anspruchs 1. Diese Maßnahme bewirkt, daß eine Dispergierung des zu sichtenden Gutes bereits vor dem Eintritt in die Sichtzone erzielt wird, und zwar dadurch, daß größere und kleinere, d.h. schwerere und leichtere Gutbestandteile durch Erreichen einer gegenüber dem Stand der Technik höheren Geschwindigkeit, nach Anspruch 2 besonders wirkungsvoll durch Erreichen der jeweiligen Geschwindigkeit des freien Falles, schon vor Erreichen der Sichtzone'voneinander getrennt werden, wodurch die nachteilige Konzentration der Gutbestandteile beim Eintritt in die Sichtzone vermieden wird. Nach dem Eintritt in die Sichtzone ist die Ablenkung der Fallbewegung aus der Vertikalen abhängig von der Größe der einzelnen Gutbestandteile, deren Dichte und deren Vertikalgeschwindigkeit. Je größer diese ist, um so geringer ist die Verweilzeit in der Sichtzone und um so geringer ist die Ablenkung. Die Erfindung gibt die Lehre, daß die einzelnen Gutbestandteile dadurch sehr scharf getrennt werden können, daß sie mit den erheblichen Unterschieden hinsichtlich ihrer Vertikalgeschwindigkeiten, nach Anspruch 2 etwa mit ihrer Fallgeschwindigkeit, in die Sichtzone eintreten.This object is achieved with the measure according to the characterizing part of claim 1. This measure has the effect that the material to be sifted is dispersed even before it enters the viewing zone, namely that larger and smaller, ie heavier and lighter, material stocks parts is avoided by achieving a comparison with the prior art, higher speed, according to claim 2 particularly effective by reaching the respective speed of the free fall, are separated from each other before reaching the viewing zone ', whereby the adverse concentration of Gutbestandteile upon entry into the viewing zone. After entering the viewing zone, the deflection of the falling movement from the vertical depends on the size of the individual good components, their density and their vertical speed. The larger this is, the shorter the dwell time in the viewing zone and the less the distraction. The invention teaches that the individual good components can be separated very sharply by entering the viewing zone with the considerable differences in terms of their vertical speeds, according to claim 2, for example, with their falling speed.

Die Maßnahme nach Anspruch 3 verkürzt die Strecke, die erforderlich ist, um den Gutbestandteilen die Geschwindigkeit nach.Anspruch 1 oder 2 erreichen zu lassen, und beschleunigt die Gutbestandteile entweder so, daß sie danach insgesamt oder teilweise wieder verzögert werden oder so, daß lediglich eine Restbeschleunigung erforderlich ist.The measure according to claim 3 shortens the distance required to speed the good components . To achieve claim 1 or 2, and accelerates the good components either so that they are then delayed again in whole or in part or so that only a residual acceleration is required.

Anspruch 4 stellt auf das Erreichen einer mittleren Fallgeschwindigkeit ab, wobei die leichteren Gutbestandteile auf Grund des Luftwiderstandes abgebremst und die schweren Gutbestandteile weiterhin beschleunigt werden, ehe sie in die Sichtzone eintreten.Claim 4 is based on the achievement of an average falling speed, with the lighter material components due to the air resistance slowed down and the heavy material components were further accelerated before they entered the field of vision.

Die Ansprüche 5 bis 7 geben Vorrichtungen zur Durchführung des Verfahrens nach einer der vorbeschriebenen Maßnahmen an; in der Zeichnung sind zwei Ausführungsbeispiele dargestellt. Dabei zeigt

  • Fig. 1 einen Vertikalschnitt durch eine Gesamtanlage eines Horizontalsichters mit einer Zellenradschleuse am Eintrag und
  • Fig. 2 einen Ausschnitt aus der Anlage nach Fig. 1 bei der die Zellenradschleuse durch einen Fallschacht ersetzt worden ist.
Claims 5 to 7 specify devices for carrying out the method according to one of the measures described above; two exemplary embodiments are shown in the drawing. It shows
  • Fig. 1 shows a vertical section through an overall system of a horizontal classifier with a rotary valve at the entry and
  • Fig. 2 shows a section of the system of FIG. 1 in which the rotary valve has been replaced by a chute.

Die erfindungsgemäße Sortiervorrichtung nach Fig. 1 umfaßt ein langgestrecktes, zylindrisches oder quaderförmiges Gehäuse 19, dessen offene Stirnseiten durch angeflanschte Abdeckhauben 30, 31 abgeschlossen sind. Das Gehäuse 19 weist an seiner Oberseite im Bereich der Abdeckhaube 31 eine Einfüllöffnung 25 auf, an die sich nach oben ein Eingabeschacht 20 anschließt. An der Unterseite des Gehäuses 19 befinden sich zwei Öffnungen 32a und 32b, an deren Rand eine Trenneinrichtung 33 angeflanscht ist. Diese umfaßt zwei hintereinander in Gehäuselängsrichtung angeordnete Ausgabetrichter 34 und 36, deren Öffnungen 26 und 28 an jeweils eine Luftschleuse 37 angeschlossen sind, die ihrerseits mit ihren Austrittsöffnungen 41 in je einen zugeordneten Auffangbehälter 9 bzw. 11 münden. Als Luftschleusen 37 können - wie im dargestellten Beispielsfalle angedeutet - Zellenradschleusen vorgesehen werden.1 comprises an elongated, cylindrical or cuboid housing 19, the open end faces of which are closed by flanged covers 30, 31. The housing 19 has on its upper side in the area of the cover 31 a filling opening 25, which is adjoined at the top by an input shaft 20. At the bottom of the housing 19 there are two openings 32a and 32b, on the edge of which a separating device 33 is flanged. This comprises two dispensing funnels 34 and 36 arranged one behind the other in the longitudinal direction of the housing, the openings 26 and 28 of which are each connected to an airlock 37, which in turn has its off outlet openings 41 each in an associated collection container 9 and 11 open. Airlocks can be provided as airlocks 37, as indicated in the example shown.

Die Abdeckhaube 30 erstreckt sich kaminartig von der rechten offenen Stirnseite des Gehäuses 19 nach oben und ist an ihrem oberen Ende an eine nur teilweise dargestellte Rohrleitung 38 angeflanscht. Diese führt zu einem Zyklon 22, welcher die Abdeckhaube 30 mit Unterdruck beaufschlagt. Der Zyklon 22 ist ferner über seine Abluftleitung 24 mit der Ansaugseite eines Gebläses 1 verbunden, das in der Stirnwand der Abdeckhaube 31 mittig befestigt ist. Das Gebläse 1 saugt über die Abluftleitung 24 von dem Zyklon 22 Luft an und fördert einen Luftstrom 2 in den Innenraum 4 des Gehäuses 19. Zur Homogenisierung des Luftstroms 2 ist an der linken, offenen Stirnseite des Gehäuses 19 eine perforierte Verteilerplatte 39 angebracht. Die Verbindung der Abdeckhauben 30 und 31 mit dem Zyklon 22 sowie die Anbringung der Luftschleusen 37 an den Öffnungen 26 und 28 ermöglichen einen geschlossenen Luftkreislauf der durch den Innenraum 4 geförderten Luft.The cover 30 extends like a chimney from the right open end of the housing 19 upwards and is flanged at its upper end to a pipe 38 which is only partially shown. This leads to a cyclone 22, which applies a vacuum to the cover 30. The cyclone 22 is also connected via its exhaust line 24 to the suction side of a blower 1, which is fastened centrally in the end wall of the cover 31. The fan 1 sucks in air from the cyclone 22 via the exhaust air line 24 and conveys an air flow 2 into the interior 4 of the housing 19. A perforated distributor plate 39 is attached to the left, open end face of the housing 19 in order to homogenize the air flow 2. The connection of the covers 30 and 31 to the cyclone 22 and the attachment of the airlocks 37 to the openings 26 and 28 enable a closed air circuit for the air conveyed through the interior 4.

Die über die Einfüllöffnung 25 in den Innenraum 4 des Gehäuses 19 fallenden Gutbestandteile werden in der Sichtzone 3 von dem Luftstrom 2 des Gebläses 1 erfaßt und je nach ihrem Gewicht mehr oder weniger weit nach rechts durch den Innenraum 4 getragen. Dabei ist die von den Gutbestandteilen beschriebene Flugbahn um so kürzer, je größer ihr Gewicht ist.The material components falling into the interior 4 of the housing 19 via the filling opening 25 are detected in the viewing zone 3 by the air flow 2 of the blower 1 and, depending on their weight, are carried more or less far to the right through the interior 4. The trajectory described by the good components is shorter the greater its weight.

Am Ende ihrer Flugbahn treten die verschieden weit abgelenkten Gutbestandteile durch die nächstliegenden Öffnungen 32a und 26 bzw. 32b und 28 aus dem Gehäuse 19 aus und gelangen über die zugeordnete Luftschleuse 37 in den Auffangbehälter 9 bzw. 11 (s. Pfeile 5 und 7). Anstelle der Auffangbehälter 9 bis 11 können auch Transportbänder vorgesehen werden.At the end of their trajectory, the differently deflected material components emerge from the housing 19 through the nearest openings 32a and 26 or 32b and 28 and pass through the assigned airlock 37 into the collecting container 9 or 11 (see arrows 5 and 7). Instead of the collection containers 9 to 11, conveyor belts can also be provided.

Sehr feine Gutbestandteile gelangen vom Innenraum 4 (s. Pfeile 8) über die Rohrleitung 38 in den Zyklon 22, durch dessen untere, mit einer Luftschleuse 40 abgeschlossene Öffnung 29 diese Gutbestandteile in einen Auffangbehälter 12 fallen.Very fine material components pass from the interior 4 (see arrows 8) via the pipeline 38 into the cyclone 22, through whose lower opening 29, which is closed off by an air lock 40, these material components fall into a collecting container 12.

Oberhalb des Eingabeschachts 20 ist eine Zellenradschleuse 23 vorgesehen, die das oberhalb derselben aufgegebene Gut beschleunigt und mit einer solchen Geschwindigkeit in den Eingabeschacht 20 entläßt, daß die leichteren Gutbestandteile verzögert und die schwereren Gutbestandteile weiter beschleunigt in der Sichtzone 3 im Innenraum 4 ankommen, was im oben angegebenen Sinne ein verbessertes Sichterergebnis herbeiführt.Above the input shaft 20, a cellular wheel sluice 23 is provided, which accelerates the goods placed above them and releases them into the input shaft 20 at such a speed that the lighter material components are decelerated and the heavier material components further accelerate in the viewing zone 3 in the interior 4, which in the leads to an improved classifying result.

Fig. 2 zeigt, daß in der Anlage nach Fig. 1 der Eingabeschacht 20 durch einen ebenfalls oben am Gehäuse 19 angebrachten Fallschacht 21 ersetzt worden ist unter Wegfall der Zellenradschleuse. Oben auf dem Fallschacht 21 ist ein Aufgabetrichter 18 aufgesetzt, in den eine Aufgabeschurre 17 hineinragt. Das über diese aufgegebene Gut fällt durch den Fallschacht 21 und durch die Einfüllöffnung 25 in die in Fig. 2 nicht dargestellte Sichtzone. Die Länge des Fallschachts 21 ist so bemessen, daß das zu sichtende Gut, zumindest im Umfang seiner Hauptbestandteile, beim Durchtritt durch die Einfüllöffnung 25 etwa die Geschwindigkeit erreicht hat, die es beim freien Fall erreicht. Dadurch wird - wie oben erläutert - ein gutes Sichterergebnis erreicht.Fig. 2 shows that in the system of Fig. 1, the input shaft 20 has been replaced by a drop shaft 21 also attached to the top of the housing 19, eliminating the cellular wheel sluice. A feed hopper 18 is placed on top of the chute 21, into which a feed chute 17 projects. The abandoned good falls over this through the chute 21 and through the fill opening 25 into the viewing zone, not shown in FIG. 2. The length of the chute 21 is dimensioned such that the material to be sifted, at least in the scope of its main components, has approximately reached the speed when it passes through the fill opening 25, which it achieves in free fall. As explained above, this leads to a good sifter result.

Wenn in der vorbeschriebenen Anlage zerkleinerter Hausmüll gesichtet werden soll, wird nach Fig. 1 die Zellenradschleuse 23 beispielsweise so betrieben, daß deren Umfangsgeschwindigkeit etwa 2 m/s beträgt bei einer Länge des Eingabeschachts 20 von 0,5 bis 2 m, und wird nach Fig. 2 die Höhe des Fallschachts 21 einige Meter, beispielsweise um 4 m, betragen.If shredded domestic waste is to be sighted in the system described above, the cellular wheel lock 23 is operated according to FIG. 1, for example, in such a way that its peripheral speed is approximately 2 m / s with a length of the input shaft 20 of 0.5 to 2 m, and according to FIG 2 the height of the chute 21 is a few meters, for example by 4 m.
