Abstract

DC60 (03/06/41) In the methods and equipment for packing the appropriate amount of catalyst into the corshooting machine for core production or for the casting process, where the catalyst is removed from the pressurized vessel (11) in liquid or gaseous form and mixed with a purging gas before it is fed into the corshooting machine. The appropriate amount of catalyst is first, and the purging gas at a pressure of 0.1 to 10 bar is second, fed into the pressure vessel (15). The catalyst and purging gas are mixed in the pressure vessel (15), and the resulting mixture is fed into the corshooting machine. When the catalyst is used in liquid form, it can be transformed from liquid to gaseous form in the metering bellows (20) located between and connected to the pressurized vessel (15) and the pressure vessel (15). In the methods and equipment for packing the appropriate amount of catalyst into the machine. The cor shooting machine is used for the production of corsing, or for the casting process, in which the catalyst is removed from the pressurized vessel (11) in liquid or gaseous form and mixed with a purging gas before being fed into the cor shooting machine. An appropriate amount of catalyst is first fed, and a purging gas at a pressure of 0.1 to 10 bar is second fed into the pressure vessel (15). The catalyst and purging gas are mixed in the pressure vessel (15), and the resulting mixture is fed into the cor shooting machine. When the catalyst is used in liquid form, it can be transformed from liquid to gaseous form in the metering bellows (20) located between and connected to the pressurized vessel (15) and the pressure vessel (15).

Claims (10)

1. Method for the nutrient loading of catalysts into cor-shooting machines for production by cor-shooting machines and for casting processes in which the catalyst is removed from the pressurized vessel (11) in liquid or gaseous form and mixed with a purging gas before being fed into the cor-shooting machine. It is characterized that the nutrient loading of the catalyst is first, and the purging gas at a pressure of 0.1 to 10 bar is second, fed into the pressure vessel (15). The catalyst and purging gas are mixed in the pressure vessel (15), and the resulting mixture is fed into the cor-shooting machine. 2. Method according to claim 1, showing that the gaseous catalyst is heated to 3 to 80°C in a pressurized cell (11). 3. The method according to claim 1 is characterized by the liquid catalyst being introduced into the metering bellows (20) before being fed in gaseous form into the pressure vessel. 4. Any of the methods described in claims 1 through 3 demonstrate that the catalyst is a trimethyl amine. 5. Any of the claims in 1 to 4 characterize that after the introduction of the catalyst and purification gas mixture into the corshooting machine, additional purification gas is fed into the corshooting machine through a pressure vessel (15). 6. The method described herein fully encompasses the rights under claim 1 and as previously explained, by reference to Figures 2 and 3 of the accompanying images. 7. Equipment for the proper loading of catalysts into the cor-shooting machine for production by the Carr machine or for the casting process, consisting of a pressure-pressurized wessel (11) for catalyst loading, a pathway (12) for determining the amount of catalyst in the pressure vessel, a pathway (14) for carrying the catalyst to the delivery pipe (19) for loading the catalyst into the cor-shooting machine, and pathways (16,17) for loading the detoxification gas into the equipment, characterized by the equipment having a pressure vessel (15) located between and connected to the pressure-pressurized wessel (11) and the loading pipe (19), and the detoxification gas loading pathway (16) connected to the pressure vessel (15). 8. The instrument according to claim 7 exhibits the characteristic that the instrument has a pathway (13) for heating the catalyst in a pressure-controlled cell (11). 9. The instrument according to claim 7 is characterized by the instrument having a metering bellows (20) positioned between the pressure-controlled cell (11) and the pressure vessel (15) so that the catalyst may be transformed into a gaseous form before being fed into the pressure vessel (15). 10. The instrument fully exercises the rights under claim 1 and as described herein prior to this, by reference to Figures 2 and 3 of the accompanying illustrations (10 claims, illustrations).
