Description

Przedmiotem wynalazku jest urzadzenie do wytwarzania spienionego szkla metoda ciagla.The subject of the invention is a device for the production of foamed glass by a continuous method.

Znane sa urzadzenia do wytwarzania szkla piankowego ze sproszkowanego szkla bedace tunelowym piecem ze strefa o regulowanej temperaturze, w którym po rolkach lub na wózkach przesuwaja sie formy metalowe ze sproszkowanym szklem zmieszanym ze srodkami spieniajacymi. Znane jest z polskiego opisu patentowego nr 30587 urzadzenie do wytwarzania szkla spienionego metoda ciagla skladajace sie z pieca do topienia szkla i przybudówki bedacej komora spieniania, w której umieszczone sa obracajace sie lopatki ubijajace mase szklana i rury metalowe z otworami sluzace do wprowadzania medium spieniajacego do masy szklanej.Apparatus for producing cellular glass from pulverized glass is known a furnace with a temperature-controlled zone in which the molds slide on rolls or on trolleys metal with powdered glass mixed with blowing agents. It is known from the Polish description Patent No. 30587 device for the production of foamed glass using the continuous method, consisting of a furnace for glass melting and an annex which is a foaming chamber, in which rotating blades are placed tamping glass mass and metal pipes with holes for introducing the foaming medium into the mass glass.

Urzadzenie powyzsze dziala w sposób mechaniczny, dlatego wirujace lopatki jak równiez metalowe rury narazone sa na szybkie zuzycie z powodu mechanicznych uszkodzen jak równiez korozji przez szklo.The above device works mechanically, therefore the rotating blades as well as metal pipes are subject to rapid wear due to mechanical damage as well as corrosion by glass.

Urzadzenie wedlug wynalazku zlozone jest z pieca elektrodowego lub gazowego do topienia szkla i komory spieniania, w której rozmieszczone sa dysze oraz elektrody w postaci pretów, lub plaskie, korzystnie elektrody molibdenowe i plaskie elektrody weglowe. Na elektrodach zachodzi elektroliza stopu i wydzielaja sie gazy takie jak: tlen, wodór, siarkowodór i dwutlenek siarki. Powstajace na skutek elektrolizy gazy wchodza w reakcje z powierzchnia elektrod weglowych i nastepuje ich spalanie przez co wydzielaja sie duze ilosci dwutlenku wegla. Rozmieszczone w komorze spieniania elektrody przystosowane sado zasilania zarówno pradem stalym jak \( zmiennym, co pozwala na swobodna regulacja temperatury i stopnia spieniania masy szklanej wskutek intensywnego podgrzewania masy szklanej wydzieiuja sie w niej rozpuszczone gazy co zwieksza intensywnosc spieniania. W komorze spieniania umieszczone sa dysze dla wprowadzania medium speiniajacego, jak woda, para wodna, gazy i dysze te moga byc wykonane w plaskich elektrodach weglowych. Komora spieniania zakonczona jest w swej górnej czesci otworem i rynna wylozona materialem niezwilzalnym przez szklo, przez która spieniona masa jest doprowadzana do urzadzen formujacych i odprezajacych.The device according to the invention consists of an electrode or gas furnace for melting glass and a foaming chamber in which nozzles and electrodes are arranged in the form of rods, or flat, preferably molybdenum electrodes and flat carbon electrodes. Electrolysis of the alloy takes place on the electrodes and they separate gases such as oxygen, hydrogen, hydrogen sulfide and sulfur dioxide. Gases resulting from electrolysis enter it reacts with the surface of carbon electrodes and burns them, releasing large amounts carbon dioxide. The electrodes located in the foaming chamber are adapted to supply both electricity constant as \ (variable, which allows for free temperature control and degree of foaming of the glass mass as a result of intense heating of the glass mass, dissolved gases are released in it, which increases foaming intensity. In the foaming chamber there are nozzles for introducing the meeting medium, such as water, steam, gases and these nozzles can be made in flat carbon electrodes. Chamber is ended in its upper part with an opening and the gutter is lined with a non-wettable material by glass, through which the foamed mass is fed to the forming and stress relief devices.

W odmianie urzadzenia wedlug wynalazku komora spieniania posiada otwór spustowy skierowany do dolu przez który spienione szklo wyplywa do urzadzen formujacych i odprezajacych.2 101 261 Przedmiot wynalazku uwidoczniony jest w przykladach wykonania na rysunku, na którym fig. 1 przedsta¬ wia przekrój podluzny urzadzenia, fig. 2 — przekrój podluzny komory spieniania z przykladem rozmieszczenia elektrod, fig. 3—widok z góry komory spieniania w przekroju z odmiana rozmieszczenia elektrod i dysz oraz fig. 4 - odmiane urzadzenia w przekroju podluznym.In a variant of the device according to the invention, the foaming chamber has a discharge opening directed downwards through which the foamed glass flows into the formers and stress relievers 2 101 261 The subject matter of the invention is illustrated by the exemplary embodiments in the drawing in which Fig. 1 shows longitudinal section of the device, fig. 2 - longitudinal section of the foaming chamber with an example of arrangement of electrodes, fig. 3 - top view of the foaming chamber in cross-section with a different arrangement of electrodes and nozzles and Fig. 4 shows a variant of the device in longitudinal section.

Urzadzenie przedstawione na fig. 1 posiada piec topliwny 1 polaczony kanalem przeplywowym 3 z komora spieniania 2 posiadajaca w swej górnej czesci otwór wyplywowy 4 zakonczony rynna 5 wylozona materialem niezwilzalnym przez szklo a w komorze spieniania umieszczone sa w scianach bocznych elektrody pretowe 6. Przyklad odmiany rozmieszczenia elektrod w komorze spieniania pokazany jest na fig. 2, gdzie w scianach bocznch komory umieszczone sa plaskie elektrody weglowe 7 oraz pretowe elektrody molibdenowe 6 i na fig. 3, gdzie pretowe elektrody molibdenowe 6 umieszczone sa w scianach bocznych komory a w dnie komory umieszczone sa plaskie elektrody weglowe 7 i dysze 8 dla wprowadzenia dodatkowo gazów spieniaja¬ cych. W odmianie urzadzenia uwidocznionej na fig. 4 komora spieniania 2 zakonczona jest otworem spustowym 9 skierowanym do dolu a umieszczone w dnie komory spieniania plaskie elektrody weglowe 7 posiadaja wykonane otwory 10 spelniajace role dysz do wprowadzania dodatkowo medium spieniajacego.The device shown in Fig. 1 has a melting furnace 1 connected by a flow channel 3 with a foaming chamber 2 with an outflow opening 4 in its upper part, a finished channel 5 lined with material not wettable by glass and in the foaming chamber are placed in the side walls of the electrodes 6 An example of a variation in the arrangement of the electrodes in the foaming chamber is shown in Fig. 2, where in the side walls of the chamber there are 7 flat carbon electrodes and molybdenum rod electrodes 6 and in Fig. 3, where the molybdenum rod electrodes 6 are placed in the side walls of the chamber and in the bottom the chambers are placed flat carbon electrodes 7 and nozzles 8 to introduce additional foaming gases people. In a variant of the device shown in Fig. 4, the foaming chamber 2 ends with a drain hole 9. directed downwards and the flat carbon electrodes 7 located in the bottom of the foaming chamber are made openings 10 fulfilling the role of nozzles for additionally introducing a foaming medium.
