Description
Bei fast allen schwer zu filtrierenden Trockengütern, z. B. Mehl u. dgl., mußte man bisher als feinste Siebe Seidengaze verwenden, da es nicht möglich war, diese durch Metallgewebe zu ersetzen. Da das Drahtgewebe in der benötigten Feinheit (bis 7000 Maschen je Quadratzentimeter) nur aus runden Drähten hergestellt werden kann, wird, die Masche nach der Mitte zu enger, da an den "Kreuzungen durch den Webvorgang Verdünnungen entstehen. Das Siebgut, z. B. Mehl o. dgl., setzt sich in der Masche fest und verstopft sie. Außerdem ist die Oberfläche sehr glatt. Das Siebgut, z. B. Mehl o. dgl., rutscht darüber hinweg, besonders wenn es etwas feucht ist und sich zusammenballt.For almost all dry goods that are difficult to filter, e.g. B. flour and the like, you had to use silk gauze as the finest sieve, since it was not possible to replace them with metal mesh. Since the wire mesh in the required fineness (up to 7000 meshes per square centimeter) can only be made from round wires, the mesh becomes narrower towards the middle, as the weaving process creates dilutions at the intersections. Flour or the like gets stuck in the mesh and clogs it. In addition, the surface is very smooth.
Die Erfindung besteht nun darin, daß die in Längsrichtung laufenden Drähte zweifach gedrillt sind. Dadurch bildet sich eine Schraubenlinie. Beim Passieren des Siebgutes, z. B. Mehl o. dgl., über den mit solchen Drahtgewebe bespannten Rahmen schrauben sich die feinen Teilchen des Siebgutes durch das Gewebe hindurch. Da außerdem das Drahtgewebe eine rauheOberfläche aufweist, werden die etwa zusammengeballten Teile zerrieben. Ein Verstopfen des Gewebes ist somit unmöglich. Das Drahtgewebe ist ein vollwertiger Ersatz für Seidengaze, darüber hinaus bedeutend haltbarer und in der Herstellung wesentlich billiger. Die Erfindung ist in der Zeichnung in vergrößertem Maßstab dargestellt.The invention consists in that the running in the longitudinal direction Wires are twisted twice. This creates a helix. When passing of the material to be screened, e.g. B. flour o. The like., On the frame covered with such wire mesh The fine particles of the material to be screened screw their way through the fabric. Since also If the wire mesh has a rough surface, the roughly clumped together Parts ground up. Clogging of the tissue is therefore impossible. The wire mesh is a full substitute for silk gauze, is also significantly more durable and Much cheaper to manufacture. The invention is in the drawing on an enlarged scale Scale shown.
Zur Herstellung des Siebes nach der Erfindung werden Metalldrähte aus Kupfer, Bronze oder sonst geeigneten Legierungen gewählt, die in üblicher Weise zu einem Metallgewebe verarbeitet werden. Aus der Zeichnung ist ersichtlich, daß die in der Zeichnung waagerechten Drähte r einfache Drähte gewünschter Stärke sind, während die senkrechten Fäden 2 aus zwei miteinander verwundenen, verzwirnten oder verdrillten Drähten 3, .4 bestehen. Man kann die Drähte je nach NZaschengröße aussuchen und daher Grob- und Feinsiebe nach Wunsch herstellen, um die erforderliche lichte Maschenweite für die entsprechende Feinheit des Siebgutes zu erreichen.Metal wires are used to manufacture the screen according to the invention from copper, bronze or other suitable alloys selected in the usual way can be processed into a metal mesh. From the drawing it can be seen that the horizontal wires in the drawing are simple wires of the desired thickness, while the vertical threads 2 consist of two twisted, twisted or twisted wires 3, .4 exist. You can choose the wires depending on the Nash size and therefore produce coarse and fine sieves as required to achieve the required clearance To achieve mesh size for the corresponding fineness of the material to be screened.
