Description
Verfahren zur Herstellung von Filtern Man hat schon vorgeschlagen, Filter aus porös gesintertem Glas herzustellen, z. B. auf dem Wege, daß man den porösen Glaskörper in einen nichtporösen Behälter aus Glas einschmilzt. Solche Filter können jedoch wegen der großen Spannungsbeanspruchungen beim Einschmelzen nur mit einem verhältnismäßig kleinen Durchmesser ausgeführt werden.Process for the manufacture of filters It has already been proposed Manufacture filters from porous sintered glass, e.g. B. on the way that you can Melting porous glass body in a non-porous container made of glass. Such filters However, due to the high stresses during the melting process, they can only be used with a relatively small diameter.
Das Verfahren nach der Erfindung besteht demgegenüber darin, daß man auf den siebartig durchlochten Boden eines Metallgefäßes Glaspulver in gleichmäßiger Schicht aufbringt, worauf dieses Gefäß mit der Glaspulverschicht auf so hohe Temperatur erhitzt wird, daß das Glaspulver porös zusammensintert und sich dabei gleichzeitig mit den Gefäßwandungen fest verbindet. Dieses Verfahren ermöglicht wegen des eine Armierung der porösen Glasfilterschicht bildenden Siebbodens die Herstellung großer Filter, ohne daß die Festigkeit des Filters und seine Verbindungen mit dem Gefäß beeinflussende Selbstspannungen auftreten können. The method according to the invention consists in that one on the sieve-like perforated bottom of a metal vessel glass powder in uniform Layer applies, whereupon this vessel with the glass powder layer at such a high temperature is heated so that the glass powder sintered together porous and at the same time firmly connects to the vessel walls. This procedure allows because of the one Reinforcement of the porous glass filter layer forming sieve bottom the production of large Filter without compromising the strength of the filter and its connections with the vessel influencing self-tensions can occur.
In mehreren beispielsweisen Ausführungsformen sind Filter nach dem Verfahren der Erfindung in der Zeichnung dargestellt, und zwar zeigen Abb. I eine Ausführungsform eines solchen Filters im Schnitt, Abb. 2 und 3 eine zweite Ausführungsform im Grundriß und Querschnitt und Abb. 4 eine dritte Ausführungsform im senkrechten Schnitt. In several exemplary embodiments, filters are after Process of the invention shown in the drawing, namely Fig. I show a Embodiment of such a filter in section, Fig. 2 and 3 a second embodiment in plan and cross-section and Fig. 4 a third embodiment in the vertical Cut.
In Abb. I ist I ein zylindrisches Metallgefäß mit etwas eingezogenem unterem Rande 2. Der an der Einziehungsstelle befestigte Boden des Gefäßes besteht aus einem perforierten Bleche 3, während 4 die aus Glaspulver zusammengesinterte und mit Gefäßboden und -wandungen fest verbundene poröse Glasschicht veranschaulicht. In Fig. I, I is a cylindrical metal vessel with something retracted lower edge 2. The bottom of the vessel, which is attached to the point of insertion, is made from a perforated sheet 3, while 4 is made of glass powder sintered together and illustrated with a porous glass layer firmly connected to the bottom and walls of the vessel.
Bei der Ausführungsform nach Abb. 2 und 3, die sich besonders fürFilter mit großer Filterfläche eignet, ist 5 ein Metallrahmen, der aus Längs- und Querstäben 6 und 7 besteht, die in der Druckrichtung nach unten (vgl. Abb. 3) sich verstärken. Die Zwischenräume zwischen diesen Querstäben sind durch Platten 8 aus gesinterten porösen Glasmassen, die mit den Flächen der Stäbe 6 und 7 verschmolzen sind, ausgefüllt. Dabei erfolgt die Befestigung zweckmäßig in der Weise, daß eine Emailleschicht, mit der die Stäbe 6 und 7 zum Schutz gegen Säuren überzogen sind, gleichzeitig als Kittschicht für die gesinterte Glasmasse dient. In the embodiment according to Figs. 2 and 3, which are particularly suitable for filters with a large filter surface, 5 is a metal frame made up of longitudinal and transverse rods 6 and 7, which increase in the downward pressure direction (see Fig. 3). The spaces between these cross bars are sintered by plates 8 porous glass masses, which are fused with the surfaces of the rods 6 and 7, filled. The attachment is expediently carried out in such a way that an enamel layer, with which the rods 6 and 7 are coated to protect against acids, at the same time as Putty layer is used for the sintered glass mass.
Das Filter nach dem Ausführungsbeispiel der Abb. 4 besteht aus einem U-Eisenrahmen 9 mit zickzackförmig zwischen den Rahmenwangen befestigten Quertraversen 9', die seitliche ÖffnungenIo aufweisen, welche wiederum mit eingesetzten gesinterten porösen Glasplatten, die mit den Traversen nach dem vorstehend geschilderten Verfahren verbunden sind, ausgefüllt und abgedichtet sind. The filter according to the embodiment of Fig. 4 consists of one U-iron frame 9 with cross members fastened in a zigzag shape between the frame cheeks 9 ', which have lateral openingsIo, which in turn are sintered with inserted porous glass plates, which with the traverses according to the method described above connected, filled in and sealed.
PAENTANSPRÜCHE: I. Verfahren zur Herstellung von Filtern aus porös gesintertem Glas, dadurch gekennzeichnet, daß auf den siebartig durchlochten Boden eines Metallgefäßes Glaspulver in gleichmäßiger Schicht aufgebracht wird, worauf in bekannter Weise das Gefäß mit der Glaspulyerschicht auf so hohe Temperatur erhitzt wird, daß das Glaspulver porös zusammensintert und sich dabei gleichzeitig fest mit den Gefäßwandungen verbindet. PATENT CLAIMS: I. Process for the production of filters from porous Sintered glass, characterized in that on the sieve-like perforated bottom a metal vessel, glass powder is applied in an even layer, whereupon in a known manner the vessel with the Glaspulyerschicht heated to such a high temperature becomes that the glass powder sintered together porous and at the same time solid connects with the vessel walls.
