Description

Die Erfindung betrifft eine Vibrations-Siebmaschine, insbes. der Mehrdeck-Bauart, bei der im Einlauf der Siebmaschine eine in den Bewegungsablauf der Siebmaschine integrierte Verteil- und Segregationseinrichtung angeordnet ist.The invention relates to a vibrating screening machine, in particular of the multi-deck design, in which a distribution and segregation device integrated into the movement of the screening machine is arranged in the inlet of the screening machine.

Bei der Siebung mittel und fein disperser Stoffe und Schüttgüter ist zur Erzielung optimaler Siebleistungen und Trennschärfen die Art und Weise, wie das Siebgut auf die wirksame Siebfläche aufgegeben wird, von entscheidender Bedeutung.When sieving medium and finely dispersed materials and bulk materials, the way in which the sieved material is placed on the effective sieving surface is of crucial importance in order to achieve optimal sieving performance and separation efficiency.

Im allgemeinen werden Siebmaschinen mittels Fördergeräten wie Förderbändern, Schnecken, Vibrationsförderern usw. beschickt. Dabei wird eine mehr oder weniger gleichmäßige Verteilung des Siebgutes beim Eintritt in die Siebmaschine erreicht. In der Regel wird das Siebgut entweder direkt auf das Siebgewebe aufgeschüttet, oder es befindet sich innerhalb der Siebmaschine ein sogenanntes Prall- oder Aufgabeblech, auf das das Schüttgut aufgegeben wird, um das Siebgewebe vor Verschleiß zu schützen. Von dem Prallblech fällt das Schüttgut dann auf das Siebgewebe. Diese Art der Beschickung hat Zur Folge, daß die aktive Siebfläche nicht optimal ausgenutzt wird, weil bestimmte Siebflächen im Einlaufbereich nicht mit Produkt bedeckt werden, oder die Produktverteilung über die Breite unterschiedlich hoch ist. Häufig ist die Schichthöhe in der Mitte wesentlich höher als an den Seiten, so daß mittig eine überlastung und seitlich eine Unterlast besteht. Das wird auch nicht wesentlich bei einer Siebmaschine gemäß der DE-A-34 02 861 verbessert, bei der zwei Siebe übereinander angeordnet sind, deren Siebflächen in der Mitte nach oben gewölbt sind.In general, screening machines are fed by means of conveyors such as conveyor belts, screws, vibratory conveyors, etc. A more or less uniform distribution of the material to be screened is achieved when it enters the screening machine. As a rule, the screenings are either heaped directly onto the screen mesh, or there is a so-called baffle plate or feed plate inside the screen machine, onto which the bulk material is placed in order to protect the screen mesh from wear. The bulk material then falls from the baffle onto the screen mesh. The result of this type of loading is that the active screen area is not optimally used because certain screen areas in the inlet area are not covered with product, or the product distribution is different in the width. Often the layer height in the middle is much higher than on the sides, so that there is an overload in the middle and an underload on the side. This is also not significantly improved in a screening machine according to DE-A-34 02 861, in which two screens are arranged one above the other, the screen surfaces of which are curved upwards in the middle.

Außerdem muß bei dem zu siebenden Schüttgut, das in der Regel aus einer Mischung aus fein- und grobkörnigem Material besteht, zunächst auf dem Siebgewebe eine Segregation des Haufwerkes stattfinden, damit das Feingut durch die Siebmaschen vom Grobgut getrennt werden kann. Dieser ganze Prozeß läuft verhältnismäßig langsam ab, und die spezifischen Siebleistungen pro Quadratmeter Siebfläche sind entsprechend niedrig. Dadurch sind unverhältnismäßig große Siebmaschinen erforderlich.In addition, in the case of the bulk material to be screened, which generally consists of a mixture of fine and coarse-grained material, there must first be segregation of the pile on the screen fabric take place so that the fine material can be separated from the coarse material through the sieve mesh. This whole process is relatively slow and the specific sieving performance per square meter of sieving area is correspondingly low. As a result, disproportionately large screening machines are required.

Durch die Erfindung sollen die genannten Nachteile vermieden und die Aufgabe gelöst werden, eine Siebmaschine zu schaffen, bei der das Gut beim Auftreffen auf die Siebe bereits gleichmäßig verteilt und auch schon eine Vorsegregation gebildet ist, so daß die Siebe für ihre eigentliche Aufgabe optimal ausgenutzt werden können mit der Folge, daß die Größe der Siebmaschinen reduziert und damit der Kostenaufwand verringert werden kann.The invention aims to avoid the disadvantages mentioned and to solve the problem of creating a screening machine in which the material is evenly distributed when it hits the screens and a pre-segregation is already formed, so that the screens are optimally used for their actual task can with the result that the size of the screening machines can be reduced and thus the cost can be reduced.

Zur Lösung dieser Aufgabe, der der Gedanke zu grunde liegt, den Verteil- und Segregationsvorgang dem eigentlichen Siebprozeß vorzulagern, wird erfindungsgemäß vorgeschlagen, im Einlaufbereich der Siebmaschinen eine oder mehrere in den Bewegungsablauf der Siebmaschine integrierte Verteil- und Segregationseinrichtung anzuordnen, d.h. gleichzeitig mit der Siebmaschine eine Verteil- und Segregationseinrichtung mit in Schwingung zu setzen und dieses für den Prozeß auszunutzen.To solve this problem, which is based on the idea of placing the distribution and segregation process in front of the actual screening process, it is proposed according to the invention to arrange one or more distribution and segregation devices integrated in the screening machine's infeed area, i.e. to simultaneously set a distribution and segregation device in vibration with the screening machine and to use this for the process.

Es hat sich als zweckmäßig erwiesen, die Verteil- und Segregationseinrichtungen als auswechselbar am Rahmen der Siebmaschine anbringbare Bauelemente auszubilden. Das Rahmengehäuse ist dabei dann so gestaltet, daß in den Einlaufbereich verschiedene Verteil- und Segregationseinrichtungen eingebaut werden können, um sich den Stoff- und Produktionseigenschaften anpassen zu können. Außerdem geschieht die Produktzuführung aus sehr unterschiedlichen Richtungen, und daher ist es notwendig, auch unterschiedlich gestaltete Verteiler- und Segregationseinrichtungen zu wählen. Wichtig ist nur, daß alle die gleichen Anschlußmaße am Gehäuse haben und daher jederzeit wie ein Baukasten ausgewechselt werden können.It has proven to be expedient to design the distribution and segregation devices as components which can be interchangeably attached to the frame of the screening machine. The frame housing is then designed so that different in the inlet area Distribution and segregation devices can be installed to adapt to the material and production properties. In addition, the product is supplied from very different directions, and it is therefore necessary to choose differently designed distribution and segregation devices. It is only important that all have the same connection dimensions on the housing and can therefore be replaced at any time like a modular system.

Als Verteil- und Segregationseinrichtung kann beispielsweise ein bis auf eine Einfüllöffnung und eine Ablauföffnung für das Gut zum Siebdeck geschlossener Kasten dienen, dessen Boden im Eintrittsbereich für das Gut eine dachförmige Neigung von der Mitte zu den Seiten hin aufweist, woran sich dann ein ebener zum Siebdeck hin flach geneigter Bodenbereich anschließt.As a distribution and segregation device, for example, a box closed except for a filling opening and a drain opening for the goods to the screen deck can be used, the bottom of which in the entry area for the goods has a roof-shaped inclination from the center to the sides, followed by a level to the screen deck flat inclined floor area connects.

Abhängig von der Produktart und den Eigenschaften des zu siebenden Stoffes kann es erforderlich sein, daß in die Verteileinrichtung noch zusätzliche Verteilhilfsmittel eingebaut werden müssen. Dieses können vor dem Austritt des Gutes an der Ablauföffnung oberhalb des Bodens in der Höhe verstellbare Verteilerbleche sein, die in ihren unteren Bereichen mit sägezahnförmigen oder rechteckigen Aussparungen versehen sein können.Depending on the type of product and the properties of the substance to be screened, it may be necessary to install additional distribution aids in the distribution device. Before the goods exit at the outlet opening above the floor, these can be height-adjustable distributor plates, which can be provided with sawtooth-shaped or rectangular cutouts in their lower regions.

Für andere Produkte kann es notwendig sein, auf dem Verteilboden Leitbleche oder Leitfahnen anzubringen, die von unten durch den Verteilboden befestigt werden und einstellbar sind. Hiermit kann zusätzlich eine bessere Verteilung des Produktes über die gesamte Breite erreicht werden.For other products, it may be necessary to install baffles or vanes on the distribution floor, which are attached from below through the distribution floor and are adjustable. This also enables a better distribution of the product across the entire width.

Ein anderes Ausführungsbeispiel einer Verteil- und Segregationseinrichtung kann als mit einem oder mehreren Einlaufstutzen und einer Ablauföffnung für das Gut zum Siebdeck versehenes Gehäuse ausgebildet sein, bei dem oberhalb des horizontalen Bodenbleches zwei dachförmig von der Mitte nach außen geneigte, in unterschiedliche Neigungen einstellbare Verteilungsbleche angeordnet sind. Diese Einstellbarkeit ist wichtig, weil die Fließeigenschaften der Produkte sehr unterschiedlich sind und so die Neigung dem Produkt genau angepaßt werden kann.Another exemplary embodiment of a distribution and segregation device can be designed as a housing provided with one or more inlet connections and an outlet opening for the material to the screen deck, in which two distribution plates are arranged above the horizontal floor plate, which are inclined outwards from the center and can be adjusted to different inclinations . This adjustability is important because the flow properties of the products are very different and so the inclination can be precisely adapted to the product.

Die vorderen Kanten der Verteilungsbleche sollen in der Weise schräg geschnitten sein, daß die seitlichen Bereiche gegenüber den in der Mitte liegenden Bereichen weiter zurück liegen. Damit wird die Produktverteilung über die Breite wesentlich verbessert. Um zu erreichen, daß über diese Abwurfkanten das Gut gleichmäßig abgeworfen wird, sollen an den vorderen Kanten der Verteilungsbleche in der Höhe einstellbare Abwurfbleche vorgesehen sein. Die Fuge zwischen den Verteilungsblechen kann durch ein oberhalb der aneinandergrenzenden Kanten der beiden Verteilungsbleche angebrachtes dachförmiges einstellbares Abschirm-, Leit- oder Verteilblech für das zugeführte Gut abgedeckt werden.The front edges of the distribution plates should be cut obliquely in such a way that the lateral areas are further back than the areas in the middle. This significantly improves the product distribution across the width. In order to ensure that the material is evenly thrown over these discharge edges, height-adjustable discharge plates should be provided on the front edges of the distribution plates. The joint between the distribution plates can be covered by a roof-shaped, adjustable shielding, baffle or distribution plate for the supplied material, which is attached above the adjoining edges of the two distribution plates.

Die Siebmaschine 10 besteht, wie Fig. 1 erkennen läßt, im wesentlichen aus dem Rahmengehäuse 13 mit den Siebdecks 14, der Antriebskonsole 15 und den Vibratoren 16. AM Einlauf der Siebmaschine, d.h. vor dem obersten Siebboden 14 ist eine Verteil- und Segregationseinrichtung 11 bzw. 12 als Bausatz angebracht, so daß eine leichte Anpassung an unterschiedliche Betriebserfordernisse beim Benutzer der Siebmaschine möglich ist. Die Länge der Verteil- und Segregationseinrichtung hängt von verschiedenen Faktoren, wie Stoffeigenschaften und Breite der Siebmaschine ab. Für breite Siebmaschinen ist es denkbar, zwei Verteileinrichtungen nebeneinander zu setzen, die dann praktisch zwei Einläufe erhalten.1, consists essentially of the frame housing 13 with the screen decks 14, the drive console 15 and the vibrators 16. AM inlet of the screening machine, i.e. A distribution and segregation device 11 or 12 is attached as a kit in front of the uppermost sieve tray 14, so that easy adjustment to different operating requirements is possible for the user of the sieving machine. The length of the distribution and segregation device depends on various factors, such as material properties and width of the screening machine. For wide screening machines, it is conceivable to place two distribution devices next to one another, which then have practically two inlets.

Wenn das Produkt die Verteil- und Segregationseinrichtung verläßt, und auf den Siebboden fällt, dann ist die Segregation und die Verteilung vollkommen, so daß der Siebprozeß dadurch enorm beschleunigt werden kann, d.h. die Verweilzeit auf dem Siebgewebe wird dadurch wesentlich verkürzt und damit die spezifische Leistung gesteigert.If the product leaves the distribution and segregation device and falls onto the sieve bottom, then the segregation and the distribution are complete, so that the sieving process can be accelerated enormously, ie the dwell time on the sieve As a result, screen mesh is significantly shortened and the specific output is increased.

Bei der in Fig. 2 dargestellten Verteil- und Segregationseinrichtung 11 zeigt Fig. 2a einen Schnitt durch die Einrichtung und Fig. 2b eine Ansicht von oben auf diese Einrichtung, die aus einem bis auf eine Einfüllöffnung 18 und eine Ablauföffnung 19 an der das Gut auf den Siebboden abgegeben wird, geschlossenen Kasten 17 besteht, bei dem zwischen Seitenwänden ein Bodenteil 20 angeordnet ist, welches im Bereich der Einfüllöffnung dachförmig 20a gestaltet ist und zur Ablauföffnung hin in einen ebenen flach geneigten Teil 20b übergeht. Durch den dachartigen Bodenteil, der in der Mitte zu einem Sattel zusammenläuft, wird das eingegebene Gut sofort nach allen Seiten verteilt. Durch die Vibration wird dann das Produkt in Richtung Siebboden weiterbefördert, und gleichzeitig findet ein Schichtungs- und Segregationsprozeß durch die Vibration statt.In the distribution and segregation device 11 shown in FIG. 2, FIG. 2a shows a section through the device and FIG. 2b shows a view from above of this device, which consists of one except for a filling opening 18 and a drain opening 19 on which the goods are opened the sieve bottom is discharged, there is a closed box 17 in which a bottom part 20 is arranged between side walls, which is roof-shaped in the area of the filling opening 20a and merges into a flat, inclined part 20b towards the drain opening. Due to the roof-like bottom part, which converges to a saddle in the middle, the goods entered are immediately distributed to all sides. The vibration then transports the product towards the sieve bottom, and at the same time a stratification and segregation process takes place due to the vibration.

Zur weiteren gleichmäßigen Verteilung des Gutes kann oberhalb des Bodens 20b ein Verteilblech 21, welches in der Höhe verstellbar sein und in seinem unteren Bereich, wie Fig. 3 erkennen läßt, mit Ausnehmungen 29 oder 30 versehen sein kann, vorgesehen werden. Auch einstellbare Leitbleche oder -fahnen können zum Zweck der gleichmäßigeren Verteilung des Gutes am Boden 20b angebracht sein.For further uniform distribution of the goods, a distribution plate 21, which can be adjusted in height and can be provided with recesses 29 or 30 in its lower region, as can be seen in FIG. 3, can be provided above the base 20b. Adjustable baffles or flags can also be attached to the floor 20b for the purpose of more even distribution of the goods.

Eventuell kann am Kasten 17 auch noch eine Beobachtungsöffnung 24 vorgesehen sein, durch die die Gleichmäßigkeit der Verteilung des Gutes beobachtet werden kann.There may also be an observation opening at box 17 24 can be provided, through which the uniformity of the distribution of the goods can be observed.

Bei der Verteil- und Segregationseinrichtung 12 der Fig. 4 und 5 ist ein anderes Prinzip der Verteilung angewandt und zwar wird hier das Produkt etwa mittig in den Stutzen 25 des Gehäuses 23 aufgegeben und trifft dort zunächst zur Aufspaltung in zwei Ströme auf ein dachförmiges Gebilde 26, das zur Teilung des Materialstromes einstellbar ist. Von hier fällt das Material auf Bleche 27, die in der Neigung verstellbar sind. (Fig. 5).A different principle of distribution is used in the distribution and segregation device 12 of FIGS. 4 and 5, namely that the product is applied approximately in the middle of the connecting piece 25 of the housing 23 and first meets a roof-shaped structure 26 there for splitting into two streams which is adjustable for dividing the material flow. From here, the material falls on sheets 27 which are adjustable in inclination. (Fig. 5).

Das eintretende Material wandert nach der Teilung durch das Abschirm- und Leitblech 26 auf die Bleche 27 und wird dort durch die Vibration einerseits in Richtung Siebgewebe und andererseits durch die Neigung zu den Selten befördert.The incoming material migrates after the division through the shielding and guide plate 26 onto the plates 27 and is conveyed there by the vibration on the one hand in the direction of the screen fabric and on the other hand by the tendency towards the rare.

Durch die schrägen Zuschnitte der Bleche 27 wird erreicht, daß über die Abwurfkanten die Schichthöhe gleichmäßig über die Breite verteilt abgeworfen wird. Durch ein zusätzlich angebrachtes Blech 28,das in der Höhe verstellbar ist, kann die Abwurfkante unterschiedlich gestaltet werden, d.h. es kann ein kleines Wehr gebildet werden, oder es kann auch schräg eingestellt werden und damit erreicht werden, daS die Abwurfkante über die volle Breite das Material auf das darunterliegende Aufgabeblech 29 abwirft, das jetzt noch einen weiteren Segregationsprozeß einleitet. Von dort fließt es schließlich auf das Siebgewebe.The oblique cuts of the sheets 27 ensure that the layer height is thrown off evenly distributed over the width over the discharge edges. With an additional attached plate 28, which is adjustable in height, the discharge edge can be designed differently, i.e. a small weir can be formed, or it can also be set at an angle and thus achieve that the discharge edge over the full width Throws material onto the underlying feed plate 29, which now initiates yet another segregation process. From there it finally flows onto the screen mesh.

Natürlich kann der Einlaufstutzen 25 auch unterschiedlich gestaltet und auch etwas außermittig angeordnet werden, falls dies durch die Einbausituation erforderlich wird.Of course, the inlet connection 25 can also be designed differently and can also be arranged somewhat off-center, if this becomes necessary due to the installation situation.
