Abstract

Döküm islemleri için göbek ya da kaliplar üretimi için bir göbek fiskirtma makinesine optimize miktarda katalizör saglanmasi için bir metod ve cihaz, burada katalizör sivi ya da gaz halde basinçli bir bölmeden (11) ekstrakt edilir ve göbek fiskirtma makinesine verilmeden önce temizleyici gaz ile karistirilir, ilk olarak optimize bir miktarda katalizör ve ikinci olarak 0.1 ila 10 bardaki temizleme gazi bir basinçli kaba (15) beslenir, katalizör ve temizleme gazi basinçli kapta (15) karistirilir ve elde edilen karisim göbek fiskirtma makinesine verilir. Katalizör sivi halde kullanildiginda, basinçli bölme (15) ve basinçli kap (15) arasinda yerlesik ve ona baglanmis olan ölçme körüklerinde (20) sivi halden gaz hale dönüstürülür.A method and device for providing an optimized amount of catalyst to a core blow molding machine for the production of cores or molds for casting processes, where the catalyst is extracted from a pressurized chamber (11) in liquid or gaseous state and mixed with the scrubber gas before being dispensed into the core jetting machine. An optimized amount of catalyst and secondly, 0.1 to 10 bar of cleaning gas is fed into a pressure vessel (15), the catalyst and cleaning gas are mixed in the pressure vessel (15) and the resulting mixture is fed into the core jetting machine. When the catalyst is used in liquid form, it is converted from the liquid state to gas in the measuring bellows (20) located between the pressure chamber (15) and the pressure vessel (15).
