Description
Die vorliegende Erfindung betrifft ein Separier verfahren für pastenförmiges oder in Form von Suspen sionen oder Aufschlämmungen vorliegendes Abfallmaterial, das in Schlachtereien oder bei der Herstellung von Wein-, Fruchtsäften, Bier und dergleichen anfällt.The present invention relates to a separator process for pasty or in the form of suspensions sions or slurries of waste material present, in slaughterhouses or in the production of wine, Fruit juices, beer and the like are produced.
In Schlachtereien, bei Bierbrauereien, sowie bei der Herstellung von Wein- und Fruchtsäften fallen Mate rialien an, die ca. 8-25% Trockensubstanz aufweisen. Zur Entsorgung oder Weiterverwertung dieser Materialien müssen sie entwässert werden. Die Entwässerung dieser Ma terialien ist meistens mit großen Schwierigkeiten oder verhältnismäßig hohen Kosten verbunden. Bisher wurden derartige Materialen in der Regel durch Abdampfen des Wassers getrocknet.In slaughterhouses, at breweries, as well as at Mate produces wine and fruit juices rialien, which have about 8-25% dry matter. For the disposal or recycling of these materials they need to be drained. The drainage of this Ma is mostly with great difficulty or relatively high costs. So far such materials usually by evaporating the Water dried.
Es ist Aufgabe der vorliegenden Erfindung, ein Verfahren zur Verfügung zu stellen, welches eine Entwäs serung derartiger Materialien einem geringeren Ener gieaufwand auf mechanische Weise ermöglicht.It is an object of the present invention To provide a process that a drainage of such materials with a lower energy gi effort required in a mechanical way.
Die Aufgabe wurde durch das erfindungsgemäße Verfahren gelöst.The object was achieved by the invention Procedure solved.
Gegenstand der vorliegenden Erfindung ist demzu folge ein Verfahren zur Entwässerung von pastenförmigem oder in einer Suspension oder Aufschlämmung vorliegendem Abfallmaterial, mit einem Trockensubstanzgehalt von 8- 25 Gew.-%, welches Verfahren dadurch gekennzeichnet ist, daß das Abfallmaterial durch dauernde Homogenisierung oder Rührung in einem pumpfähigen Zustand gehalten wird, das Material in eine Siebpresse gefördert wird, es dort einer mechanischen Trennung unterworfen wird, wobei ein Filterrückstand und Siebwasser resultieren.The subject of the present invention is accordingly follow a procedure for dewatering pasty or in a suspension or slurry Waste material, with a dry matter content of 8- 25% by weight, which process is characterized that the waste material through constant homogenization or stirring is kept in a pumpable state, the material is conveyed into a screen press, it there is subjected to a mechanical separation, with a Filter residue and white water result.
Das Verfahren eignet sich vor allem für eine kon tinuierliche Arbeitsweise. Insbesondere kann es angewandt werden auf Rückstände von Schlachtereien, insbesondere zur Aufarbeitung des Inhaltes von Rinderpansen. Dieses Material, welches bisher besondere Schwierigkeiten zur Entsorgung mit sich gebracht hatte, kann nach seiner Ent wässerung problemlos einer Verbrennung zugeführt werden. Die erfindungsgemäße Aufarbeitung dieses Materials hat zudem noch den Vorteil, daß feste Komponenten wie Medi kamentenkapseln oder Magnete, welche sich häufig in den Rinderpansen befinden, durch das Homogenisations- oder Rührverfahren am Boden des Homogenisiergefäßes ablagert werden. Dadurch gelangen diese Teile nicht in die Siebpresse, was Schäden oder Betriebsstörungen vermeidet.The method is particularly suitable for a con meticulous way of working. In particular, it can be applied are on residues from slaughterhouses, in particular for processing the contents of beef rumen. This Material that has so far been particularly difficult Disposal may have after its ent irrigation can be easily incinerated. The processing of this material according to the invention has also the advantage that solid components such as Medi capsules or magnets, which are often found in the Bovine rumen are located through the homogenization or Stirring method deposited at the bottom of the homogenization vessel become. As a result, these parts do not get into the Screen press, which prevents damage or malfunctions.
Abfallprodukte mit ähnlicher Konsistenz fallen ebenfalls in anderen Gebieten an, wie beispielsweise bei der Fruchtsaftpressung (Trester) oder bei der Herstellung von Bier. Das Verfahren ist ebenso für derartige Produkte geeignet.Waste products with a similar consistency fall also in other areas, such as at the fruit juice squeeze (pomace) or during production of beer. The procedure is also for such products suitable.
Als Separator für die Abtrennung von Wasser ist beispielsweise eine Schneckensiebpresse oder eine Band siebpresse geeignet. Vorzugsweise gelangt eine sogenannte Schneckensiebpresse zum Einsatz. Zur Regelung der Pumpfä higkeit des Ausgangsmaterials kann nach Bedarf ein Anteil des abgepreßten Siebwassers wiederum in die zu homogeni sierende oder zu rührende Masse zurückgeleitet werden.As a separator for water separation for example a screw press or a belt screen press suitable. A so-called Screw screen press for use. To regulate the pump Ability of the starting material can be a proportion if necessary of the pressed white water again in the too homogeneous mass or to be stirred mass are returned.
Das Verfahrensmerkmal des ständigen Rührens oder Homogenisierens bewirkt, daß das genannte Abfallmaterial problemlos mit einer Siebpresse verarbeitet werden kann. Wird das Material jedoch nicht ständig homogenisiert, führt dies in den Siebpressen zu Verstopfungen, was ein kontinuierliches Arbeiten unmöglich macht. Überdies wür den Medikamentenkapseln oder Magnete ebenfalls in die Siebpresse gelangen, was wie bereits erwähnt zu Störungen oder Beschädigungen führen kann.The procedural feature of constant stirring or Homogenization causes the waste material mentioned can be easily processed with a screen press. However, if the material is not constantly homogenized, this leads to blockages in the screen presses what a makes continuous work impossible. Moreover, the medicine capsules or magnets also in the Sieve press arrive, which, as already mentioned, leads to malfunctions or cause damage.
Die vorliegende Erfindung wird anhand der beilie genden Zeichnungen näher erläutert. Es zeigt The present invention is based on the enclosed ing drawings explained in more detail. It shows
Fig. 1 eine Pansenseparieranlage, umfassend eine Homogenisiervorrichtung mit Rührwerk und einen Separator und Fig. 1 shows a rumen separation system, comprising a homogenizer with agitator and a separator
Fig. 2 eine Darstellung einer geeigneten Separa torvorrichtung. Fig. 2 is an illustration of a suitable Separa gate device.
Fig. 1 zeigt eine Anlage mit einem Homogenisa tionsbecken 1, welche die zur Homogenisierung enthaltende Masse 2 enthält. Zur Homogenisierung dient ein Rührwerk 3 mit dem Rührer 4. Die durch Homogenisation pumpbar ge machte Masse 2 wird durch das Ansaugrohr 5 durch die stu fenlos einstellbare Pumpe 6 angesogen und über die Lei tung 3 in den Separator 9 gefördert. Im Separator 9, der auf dem Träger 10 steht, wird die Aufschlämmung sepa riert, wobei das "feste" Material ausgestoßen und aufge fangen wird, während das Siebwasser über eine Leitung 11 und eine Siebwasserpumpe über eine Leitung 14 in eine Kläranlage und gegebenenfalls teilweise über eine Leitung 15 in das Homogenisationsgefäß zurückgeführt wird. An der Siebwasserpumpe ist ein Mehrweghahn angeordnet, wel cher in Abhängigkeit von der Konsistenz des zu homogenisierenden Materials gesteuert wird. Das zu homo genisierende Material 2 ist beispielsweise das Material aus dem Pansen von geschlachteten Rindern. Bei der Lage rung oder Deponierung ist dieses Material mit starken Ge ruchsemissionen verbunden. Deshalb ist eine wirksame Ver dickung des Materials schon in der Schlachterei wünschenswert, damit das "feste" Material problemlos einer Verbrennung zugeführt und das Siebwasser einer Abwas serreinigung unterworfen werden kann. Die Rührung kann durch ein normales Rührwerk erfolgen, wobei jedoch auch andere derartige Verfahren, wie Homogenisation geeignet sind. Vom Separator 9 geht zusätzlich ein Überlaufrohr 12 aus, durch welches Material, das durch den Separator nicht aufgenommen werden kann in das Homogenisations- oder Rührgefäß 1 zurückgeführt wird. Die in Fig. 1 sche matisch dargestellte Anlage kann, solange zu rührendes oder homogenisierendes Material 2 im Gefäß 1 vorhanden ist, kontinuierlich arbeiten. Fig. 1 shows a system with a homogenization tank 1 , which contains the mass 2 contained for homogenization. A stirrer 3 with stirrer 4 is used for homogenization. The mass made by homogenization ge made mass 2 is sucked through the intake pipe 5 by the steplessly adjustable pump 6 and conveyed via the line 3 in the separator 9 . In the separator 9 , which stands on the carrier 10 , the slurry is separated, the "solid" material being expelled and caught, while the white water via a line 11 and a white water pump via a line 14 into a sewage treatment plant and, if appropriate, partially via a line 15 is returned to the homogenization vessel. A reusable tap is arranged on the white water pump, which is controlled depending on the consistency of the material to be homogenized. The material 2 to be homogenized is, for example, the material from the rumen of slaughtered cattle. This material is associated with strong odor emissions when stored or deposited. Therefore, an effective thickening of the material is desirable even in the slaughterhouse so that the "solid" material can be easily incinerated and the white water can be subjected to water purification. The stirring can be carried out using a normal stirrer, although other such processes, such as homogenization, are also suitable. From the separator 9 there is also an overflow pipe 12 , through which material which cannot be taken up by the separator is returned to the homogenization or stirring vessel 1 . The plant shown in FIG. 1 can work continuously as long as material 2 to be stirred or homogenized is present in the vessel 1 .
Fig. 2 zeigt eine typische Separatoreinrichtung, nämlich eine Schneckensiebpresse, wie sie vorzugsweise für die erfindungsgemäße Vorrichtung geeignet ist. Die Vorrichtung weist einen Antriebsmotor 16 auf, welcher mit einer Förderschnecke 17 verbunden ist, die das durch den Einlauf 18 hineingepumpte Material in die Siebkammer 19 fördert. Hier wird durch das Sieb 20 das Siebwasser ausgepreßt, welches durch den Auslauf 21 austritt. Gleichzeitig wird das sich in der Kammer befindliche Ma terial verdichtet und aus der Austrittsöffnung 22 aus dem Siebraum 19 ausgepreßt. In der Gegend der Austritts öffnung 22 befindet sich ein Ausstoßregler 23, welcher dafür sorgt, daß das gepreßte Material ausgestoßen wird. Vorzugsweise umfaßt die Separatorvorrichtung einen Vibrator 24, der dazu dient, das Material auch während dem Pressvorgang möglichst homogen zu halten. Fig. 2 shows a typical separator, namely a Schneckensiebpresse as is preferably suitable for the inventive device. The device has a drive motor 16 which is connected to a screw conveyor 17 which conveys the material pumped through the inlet 18 into the sieve chamber 19 . Here the white water is pressed out through the sieve 20 , which emerges through the outlet 21 . At the same time, the material located in the chamber is compressed and pressed out of the outlet opening 22 from the screen space 19 . In the area of the outlet opening 22 there is an ejection regulator 23 which ensures that the pressed material is ejected. The separator device preferably comprises a vibrator 24 which serves to keep the material as homogeneous as possible even during the pressing process.
Die erfindungsgemäße Vorrichtung kann in ver schiedenen Größen hergestellt werden, je nach dem an fallenden Material, welches zu entwässern ist. Obschon in der bevorzugten Ausführungsform gemäß den beiliegenden Fig. 1 und 2 eine Schneckenpresse zur Anwendung ge langt, sind ebenfalls andere Pressen im erfindungsgemäßen Verfahren anwendbar.The device according to the invention can be manufactured in different sizes, depending on the material to be drained. Although a screw press is used in the preferred embodiment according to the accompanying FIGS. 1 and 2, other presses can also be used in the method according to the invention.
