Description
Den Gegenständ der Erfindung bildet eine Preßvorrichtung zum Abpressen von Flüssigkeiten und Ölen mittels des Preßdruckes einer in einem Zylinder drehbar angeordneten Schnecke.The subject of the invention forms a pressing device for pressing of liquids and oils can be rotated in a cylinder by means of the pressing pressure arranged snail.
Von den bekannten Pressen dieser Art unterscheidet sich die Erfindung durch die besondere Gestaltung des Preßzylinders und der dadurch erzielten vorteilhaften Verbesserung des Preßvorganges.The invention differs from the known presses of this type due to the special design of the press cylinder and the resulting advantageous Improvement of the pressing process.
Bekanntlich sind die Preßzylinder der Schneckenpressen, die zum Abpressen von Flüssigkeit oder Öl enthaltenden Massen dienen, an geeigneten Stellen des Zylinders mit einer größeren Anzahl feiner, entsprechend geformter Bohrungen versehen, aus denen die Flüssigkeit oder das Öl unter der Einwirkung des Preßdruckes entweichen kann.It is well known that the press cylinders of the screw presses are used for pressing of liquid or oil-containing masses are used at suitable points on the cylinder provided with a larger number of fine, correspondingly shaped holes from which the liquid or oil escape under the action of the pressure can.
Bei diesen bekannten Bauarten ist der wegen der feinen Bohrungen aufzuwendende hohe Preßdruck vom Nachteil. Auch das Reinigen der vielen feinen Bohrungen in der Zylinderwandung ist mühsam und zeitraubend. Da wegen dis erforderlichen sehr kleinen Durchmessers dieser feinen Bohrungen auch der Querschnitt derselben nur sehr gering ist, wird es, um den Preßdruck zu begrenzen, notwendig, eine große Anzahl dieser feinen Bohrungen in den Preßzylinder anzuordnen, so daß dann besonders bei größeren Pressen die durch die große Menge dieser feinen Bohrungen bedingten langwierigen Wartungsarbeiten als besonders nachteilig empfun= den werden.In these known types of construction, because of the fine bores, the one that has to be expended high pressure at the disadvantage. Also cleaning the many fine bores in the Cylinder wall is tedious and time consuming. Because of the very small required The diameter of these fine bores and the cross section of the same are only very small is, in order to limit the pressing pressure, it becomes necessary to use a large number of these to arrange fine bores in the press cylinder, so that then especially with larger ones Pressing the lengthy ones caused by the large number of these fine bores Maintenance work is perceived as particularly disadvantageous.
Diesen Übelstand vermeidet die Erfindung in vorteilhafter Weise, und zwar besteht sie darin, daß der Preßzylinder aus aneinandergereihten Ringscheiben besteht, die derartig angeordnet sind, daß zwischen den einzelnen Scheiben je ein feiner Spalt frei bleibt, durch die die beim Preßvorgang frei werdende Flüssigkeit abfließen kann.The invention avoids this drawback in an advantageous manner, and although it consists in the fact that the press cylinder consists of lined-up ring disks exists, which are arranged in such a way that one each between the individual disks A fine gap remains free through which the liquid released during the pressing process can drain.
In der Zeichnung ist die beispielsweise Ausführung des Erfindungsgegenstandes in einem Längsschnitt dargestellt. Hierin ist a die drehbar gelagerte Preßschnecke; b und c sind die zu einem Preßzylinder aneinandergereihten Ringscheiben, die miteinander die Ringspalten d bilden. Die Distanzstücke e regeln die Spaltweite.In the drawing is an example of the embodiment of the subject matter of the invention shown in a longitudinal section. Here a is the rotatably mounted press screw; b and c are the ring disks lined up to form a press cylinder, which are connected to one another the annular gaps d form. The spacers e regulate the gap width.
Das zu entwässernde oder zu entölende Preßgut wird bei f aufgegeben und vermittels der sich drehenden Schnecke a in dem lamellierten Zylinder bei gleichzeitiger Fortbewegung einem Preßvorgang unterworfen. Hierbei tritt die aus dem Preßgut frei werdende Flüssigkeit in die zahlreichen Ringspalten ein und fließt von dort ab, während das abgepreßte Gut bei g die Presse verläßt.The pressed material to be dewatered or de-oiled is given up at f and by means of the rotating screw a in the laminated cylinder at the same time Movement subjected to a pressing process. This releases the material from the pressed material developing liquid enters the numerous annular gaps and flows off from there, while the pressed material leaves the press at g.
Da infolge der großen Anzahl und Länge der rings um den Preßzylinder verlaufenden Spalten das Preßgut etwa wie auf einem Spaltfilter lagert, so sind auch die Kriechwege der unter Einwirkung des Preßdruckes aus den Kapillaren des Preßgutes abwandernden Flüssigkeit sehr viel geringer, als es sonst bei den bekannten gelochten Preßzylindern der Fall ist. Hierdurch wird sowohl die Preßleistung als auch der Kraftverbrauch in vorteilhafter Weise verbessert.As a result of the large number and length of around the press cylinder running gaps the material to be pressed is roughly as stored on a slotted filter, so are also the creepage distances of the under the action of the pressure from the capillaries of the Fluid migrating from the pressed material is much less than is otherwise the case with the known perforated press cylinders is the case. As a result, both the pressing performance as the power consumption is also improved in an advantageous manner.
Durch einfaches Auseinandernehmen des den Preßzylinder bildenden Ringscheibenpaketeswerden die Ringspalten vollständig freigelegt und können leicht und mühelos gereinigt werden.By simply dismantling the ring disk pack that forms the press cylinder the ring gaps are completely exposed and can be cleaned easily and effortlessly.
