Description

Spaltsieb mit Schaber zur Siebreinigung Das Offenhalten von Sieben, in diesem Fall von Spaltsieben, erfolgt häufig durch hin und her gleitende Schaber, die in der Längsrichtung des Siebes arbeiten. Verläuft die Längsrichtung des Spaltes in demselben Sinne wie die Bewegungsrichtung des Schabers zum Sieb, so arbeitet sich der Schaber, welcher im allgemeinen aus einem Stück Blech besteht, in das Sieb ein, es entstehen Nuten in dem Schaber, der Schaber wird allmählich rechenartig gezinkt, und diese Verformung des Schabers bewirkt einen schnellen Verschleiß des Spaltsiebes. Die Längsdrähte oder Stäbe des Siebes werden, da der Schaber nunmehr nicht nur von oben, sondern durch die; rechenartigen Zinken auch von der Seite Spaltsiebstäbe oder Drähte anfaßt, schneller verschlissen und die Spaltweite größer, was eine, gröbere Körnung bedingt.Slotted sieve with scraper for cleaning sieves Keeping sieves open, in this case of wedge wire screens, often done by scrapers sliding back and forth, working in the longitudinal direction of the screen. Runs the longitudinal direction of the gap so works in the same sense as the direction of movement of the scraper to the screen the scraper, which generally consists of a piece of sheet metal, into the sieve one, there are grooves in the scraper, the scraper gradually becomes rake-like dovetailed, and this deformation of the scraper causes rapid wear of the Wedge wire screen. The longitudinal wires or rods of the screen become as the scraper is now not just from above, but through; Rake-like prongs also from the side of wedge wire rods or touches wires, worn out faster and the gap width larger, what a, coarser grain conditional.

Diesen Übelstand schließt der Gegenstand dieser Erfindung im folgenden beschriebenen Verfahren aus. , Der Grundgedanke besteht darin, daß beim Gleiten auf dem Sieb des Schabers die von jedem Punkt der Berührungsfläche des Schabers mit dem Sieb beschriebene Linie die Längsdrähte oder Stäbe des Spaltsiebes unter einem Winkel schneidet. Hierdurch wird erreicht, daß eine gleichmäßige Abnutzung der Berührungsfläche des Schabers erfolgt, also eine Nutenbildung mit den eingangs erwähnten nachteiligen Folgeerscheinungen ausgeschlossen ist.The subject matter of this invention closes this drawback in the following procedure described. 'The main idea is that when sliding on the screen of the scraper from each point of the contact surface of the scraper Line described with the sieve underneath the longitudinal wires or bars of the wedge wire cuts at an angle. This ensures that even wear is achieved the contact surface of the scraper takes place, so a groove formation with the initially adverse consequences mentioned is excluded.

Einige Beispiele gemäß Fig. i, a und 3, die im Sinne dieses Verfahrens wirken: Es bedeuten R-R den Rahmen des Spaltsiebes, D die Drähte oder Stäbe des Spaltsiebes, Qu die Querstäbe des Spaltsiebes, S das Schabeblech des Schabers, der Pfeil die Bewegungsrichtung des Schabeblechies.Some examples according to Fig. I, a and 3, which in the sense of this method work: R-R mean the frame of the wedge wire screen, D the wires or rods of the Slotted screen, Qu the cross bars of the slotted screen, S the scraper plate of the scraper, the Arrow the direction of movement of the scraper plate.

Fig. i. Das Spaltsieb, dessen Spalten früher in der Bewegungsrichtung des Schabers verlief, ist so eingebaut, daß nunmehr die Spalten in einem Winkel zur Bewegungsrichtung des Schabers verlaufen.Fig. I. The wedge wire screen whose columns are earlier in the direction of movement the scraper is built in so that the gaps are now at an angle run towards the direction of movement of the scraper.

Fig. a. Der Schaber ist so gesteuert, daß seine Bewegungsrichtung in einem Winkel zur Richtung der Spalten der Siebe verläuft.Fig. A. The scraper is controlled so that its direction of movement at an angle to the direction of the columns of the screens.

Fig. 3. Das Sieb ist so konstruiert, daß ein Teil der Spalten des Siebbelags unter einem Winkel nach rechts, der folgende Teil nach links usw. abwechselnd von der Bewegungsrichtung des Schabers aus verläuft. Selbstredend gestattet das Verfahren noch andere Konstruktionen.Fig. 3. The sieve is constructed so that part of the columns of the Screen lining at an angle to the right, the following part to the left, etc. alternately runs from the direction of movement of the scraper. Of course, that allows Process still other constructions.
