Description

Die Erfindung bezieht sich auf ein Siebblech für Filterpressen, in denen das zu filternde Material mit starkem Druck durch nebeneinander angeordnete Tücher hindurchgepreßt wird Zwischen diesen Tüchern pflegt man bisher Drahtgeflechte anzuordnen. Diese Drahtgeflechte haben den Nachteil, daß -die Tücher, wenn die Maschen im Drahtgeflecht zu weit sind, sich berühren und die Leistung der Presse dadurch beeinträchtigt wird. Es ist anzustreben, daß die Tücher möglichst frei hängen, um einen reichlich freien Durchgang zu gewährleisten. The invention relates to a screen plate for filter presses, in which the material to be filtered with strong pressure through juxtaposed Cloths are pressed through. Up to now, wire meshes have been used between these cloths to arrange. These wire meshes have the disadvantage that -the cloths when the mesh are too far in the wire mesh, touch each other and thereby the performance of the press is affected. It is desirable that the cloths hang as freely as possible to ensure an ample free passage.

Ein weiterer Nachteil besteht darin, daß die Knoten des Drahtgeflechtes das Gewebe der Tücher deformieren und beschädigen. Das Sieb nach der Erfindung vermeidet die obengenannten Nachteile. Es hält die Tücher im Abstand voneinander und, da das Sieb selbst sehr erheblichen freien Durchgang hat, ist ein schneller Filtervorgang gewährleistet. Durch die Abplattungen der bei Dreschmaschinensieben bekannten, nach beiden Seiten durchgedrückten liegelförmigen Durchpressungen wird den Tüchern eine gute ebene Auflagemöglichkeit gegeben, so daß eine Deformierung derselben nicht eintreten kann.Another disadvantage is that the knots of the wire mesh deform and damage the fabric of the towels. The sieve according to the invention avoids the above disadvantages. It keeps the wipes at a distance from each other and, since that Sieve itself has a very substantial free passage, is a faster filtering process guaranteed. Due to the flattening of the known in threshing machine sieves, after Lie-shaped press-throughs pressed through on both sides becomes one of the wipes good level support is given, so that a deformation of the same is not can occur.

Die Reinigung der Filterpresse ist durch diese Anordnung ebenfalls beschleunigt möglich.The cleaning of the filter press is also possible with this arrangement accelerated possible.

Die Zeichnung gibt ein Ausführungsbeispíel. The drawing gives an example.

Fig. I zeigt die Draufsicht auf ein Bruchstück eines Siebes nach der Erfindung. Den nach der Seite des Beobachters durchgedrückten kegelförmigen Durchdrückungen A schließen sich die nach der entgegengesetzten Seite durchgedrückten ebensolchen Durchdrückungen B an. Beide Durchdrückungen sind mit Abplattungen C versehen. Fig. I shows the plan view of a fragment of a sieve the invention. The cone-shaped one pushed through to the side of the observer Depressions A close those depressed on the opposite side just as such indentations B. Both impressions are flattened C Mistake.

Fig. 2 zeigt den Schnitt nach der Linie A-B und Fig. 3 den Schnitt nach der Linie C-D. Fig. 2 shows the section along the line A-B and Fig. 3 shows the section after the line C-D.

Zwischensiebe nach der Erfindung gestatten eine Beschleunigung der Filterpressenarbeit und bewirken eine Schonung der Tücher. Intermediate screens according to the invention allow an acceleration of the Filter press work and cause a protection of the cloths.

Claims (1)

PATENTANSPRUCH: Zwischensiebe für Filterpressen mit abwechselnd nach beiden Seiten durchgedrückten kegelförmigen Erhöhungen und Vertiefungen, dadurch gekennzeichnet, daß die kegelförmigen Vertiefungen und Erhöhungen abgeplattet sind, so daß sie in ihrer Gesamtheit beiderseits des Siebes eine ebene Auflagefläche bilden. PATENT CLAIM: Intermediate screens for filter presses with alternating after conical elevations and depressions pressed through on both sides, thereby characterized in that the conical depressions and elevations are flattened, so that in their entirety they form a flat support surface on both sides of the screen.
