Description
Filterplatte, bei welcher die Durchflußöffnungen durch Schlitze und Herausbiegen des zwischen zwei Schlitzen liegenden Streifens gebildet werden.Filter plate, in which the flow openings through slots and Bending out of the strip lying between two slits are formed.
Es ist bereits bekannt, durch Zusammensetzen zweier oder mehrerer Elemente Filtriervorrichtungen zu bilden, bei denen die Durchgangsöffnungen durch Stege dergestalt überdeckt werden, daß zwisdhen den Rändern der Lochung und dem Stege feine Durchgangs öffnungen bleiben. It is already known by putting two or more together Elements to form filtering devices, in which the passage openings through Bridges are covered in such a way that between the edges of the perforation and the Bars remain fine through-openings.
Die Zusammensetzung dieser Filtriervorrichtungen ist zeitraubend und umständlich, und sie ist insbesondere für kleinere Filtriervorrichtungen, beispielsweise für Kaffeefilter, unbrauchbar. The assembly of these filter devices is time consuming and cumbersome, and it is particularly useful for smaller filtering devices, for example for coffee filters, useless.
Gemäß Erfindung werden nun aus einer Platte schmale Streifen an den Längsseiten losgeschert und aus der Platte herausgebogen, so daß sie Stege bilden. According to the invention, narrow strips are now made of a plate Long sides sheared loose and bent out of the plate so that they form webs.
Die Fihriervorrichtung besteht dann aus dem Ganzen und sie ist nicht nur wohlfeil, da diese Bildung der Stege mit Hilfe eines groben Stempels erfolgen kann, sondern auch einfach und bequem zu handhaben. The guiding device then consists of the whole and it is not only cheap, since this formation of the webs is done with the help of a coarse punch can, but also easy and convenient to use.
Es ist zwar schon bekannt, Stege auf diese VVeise zu bilden, sie dienen aber bei den bekannten Vorrichtungen nur zur Versteifung schwacher, leicht biegsamer Bleche. It is already known to form bridges in this way, they but serve in the known devices only to stiffen weak, light flexible sheet metal.
Die Ränder der Lochungen können hierbei hochgebogen sein, sodaß die Mitnahme der abzusondernden Bestandteile beim seitlichen Abfließen restlos verhindert wird. The edges of the holes can be bent up so that the Entrainment of the components to be separated out when draining off to the side is completely prevented will.
Im der Zeichnung ist als Ausführungsbei spiel ein Kaffeefrichter dargestellt, und zwar zeigt Abb. I einen Längsschnitt und Abb. 2 einen Grundriß des Siebes, während in den Abb. 3 und 4 zwei zueinander senkrechtstehende Schnitte durch die Filterplatte in vergrößertem Maßstabe wiedergegeben sind. In the drawing, a coffee funnel is playing as Ausführungsbei shown, namely Fig. I shows a longitudinal section and Fig. 2 shows a plan of the sieve, while in Figs. 3 and 4 two mutually perpendicular cuts are reproduced by the filter plate on an enlarged scale.
Im Ausführungsbeispiel sind dieLochungena des Siebes durch Stege c überdeckt. Znvischen der Platte, und den Stegen c werden die Durchtrittsöffnungen e gebildet. Die Ränder der Lochungen a sind hochgebogen, so daß eine Art Damm vor den Löchern errichtet wird. In the exemplary embodiment, the perforationsa of the screen are through webs c covered. Between the plate and the webs c become the passage openings e formed. The edges of the perforations a are bent up, so that a kind of dam in front the holes is built.
Die Siebplatte b ist im Ausführungsbeispiel im Trichter d auswechselbar angeordnet Man kann aber auch die Stege c unmittelbar aus dem Trichterboden herausbiegen. In the exemplary embodiment, the sieve plate b can be exchanged in the funnel d but you can also bend the webs c directly out of the funnel bottom.
Es leuchtet ohne weiteres ein, daß durch die Stege c der Durchtritt der Flüssigkeit durch die Lochungen a zunächst verhütet und hierbei die Stoßenergie der Flüssigkeit vernichtet wird. Bei der Geschwindigkeitsvermindrung sondern sich die festen Bestandteile aus und sie werden auf der Platte zurüclçgehalten, insbesondere restlos dann, wenn die Ränder der Löcher a leicht nach oben gebogen sind. It is obvious that the passage through the webs c the liquid through the perforations a initially prevented and thereby the impact energy the liquid is destroyed. With the speed reduction separate the solid components and they are retained on the plate, in particular completely when the edges of the holes a are slightly bent upwards.
