Definitions
- This invention relates to a method and apparatus for the supply of an optimised quantity of catalyst to a core shooting machine for the manufacture of cores and moulds for casting processes wherein the catalyst is extracted from a pressurised vessel in liquid or gaseous form and is mixed with a purging gas before it is introduced into the core shooting machine.
- the document DE-A-2413537 teaches a method and an apparatus for the supply of a catalyst to a core shooting machine according to the preamble of claim 1 and 6 respectively.
- TMA trimethylamine
- a method for the manufacture of cores for casting processes is described in DE 19706472.8 in which gaseous trimethylamine is conducted through parts of a metering device and then, in a concentration of from 0.01 to 0.12 wt-% based on the quantity of sand used per core, it is conducted into the core shooting machine, and is there brought into contact with the sand.
- the gaseous trimethylamine is exposed to a purging gas.
- a connector is located in the conduit for the purging gas which in this manner is brought into contact with the catalyst.
- the object of the invention therefore is to provide a method and apparatus for adding an optimised quantity of catalyst to a core shooting machine for the production of cores or moulds for casting processes in which it is ensured that the core shooting machine is exposed to the optimised quantity of catalyst in the shortest possible time.
- a method for the supply of an optimised quantity of catalyst to a core shooting machine for the manufacture of cores or moulds for casting processes wherein a catalyst is extracted from a pressurised vessel (1) in liquid or gaseous form and is mixed with a purging gas before it is introduced into the core shooting machine, characterised in that firstly an optimised quantity of catalyst and secondly the purging gas at a pressure of 0.1 to 10 bar are fed into a pressure container (15), the pressure container is then closed so that the catalyst and purging gas are mixed in the pressure container (15), and the resulting mixture is introduced into the core shooting machine.
- core shooting machine shall be understood to include devices or apparatus used in foundries for the manufacture of moulds for casting processes.
- the catalyst may be for example a tertiary amine (such as trimethylamine), methyl formate, sulphur dioxide or carbon dioxide.
- the method is particularly useful for producing cores or moulds using a benzyl ether resin and an isocyanate and a tertiary amine such as triethylamine as catalyst.
- a gas bottle may be used for example as the pressurised vessel containing the catalyst.
- air is used as the purging gas but other gases, for example carbon dioxide, may be used.
- the supply of purging gas to the pressure container at 0.1 to 10 bar makes it possible to adjust the pressure in the pressure container within the range from 0.1 to 10 bar.
- the catalyst supply takes place through a valve.
- the optimised quantity of catalyst depends on the size of the core or mould being produced, and is determined in advance on the basis of various parameters for a particular core or mould.
- the catalyst in gaseous form is heated in the pressurised vessel to 3 to 80 °C to facilitate contact between the catalyst and the purging gas.
- the catalyst is conducted to metering bellows in liquid form before being fed in gaseous form to the pressure container.
- the use of the metering bellows is advantageous because although heat is extracted from the surroundings during the transformation of the catalyst from the liquid to the gaseous form the metering bellows remain able to continue to function over extended periods of operation when compared with other conveying equipment. It is particularly advantageous that the metering bellows can be installed in a relatively simple manner because older core or mould production plants can be adapted to use this embodiment of the method of the invention.
- trimethylamine is used as the catalyst, and it is advantageous that when using trimethylamine the quantity of catalyst can be kept relatively small because the nuisance from odour when cores are subsequently stored before use can largely be avoided.
- apparatus for the supply of an optimised quantity of catalyst to a core shooting machine for the manufacture of cores or mould for casting processes comprising a pressurised vessel for containing the catalyst, means for conducting the catalyst to a conduit for supplying the catalyst to a core shooting machine, and means for supplying a purging gas to the apparatus, characterised by means for determining the quantity of catalyst in the pressurised vessel, and in that the apparatus also has a pressure container located between and connected to the pressurised vessel and the supply conduit, and the purging gas supply means is connected to the pressure container, the apparatus further comprising valves to close the pressure container, so that an optimised mixture of catalyst and purging gas present in the pressure container may be introduced into the core shooting machine.
- the apparatus may also have a heater for heating the catalyst in the pressurised vessel.
- Such apparatus is suitable for use when the catalyst in the pressurised vessel is in gaseous form.
- the apparatus may have metering bellows located between the pressurised vessel and the pressure container so that the catalyst may be transformed into the gaseous form before being fed into the pressure container.
- a catalyst is contained in a pressurised vessel (1), which may be a simple gas bottle, and the pressurised vessel (1) is located on scales (2) in order to determine its contents.
- the pressurised vessel (1) can be heated by means of heater (3).
- the catalyst is conducted through a valve (4) into supply conduit (5) which leads directly to the a core shooting machine (not shown).
- a purging gas is introduced directly into the supply conduit (5) through conduit (6).
- the quantity of catalyst which reaches supply conduit (5) is reduced.
- the pressure selected in the conduit (6) for the purging gas cannot be too great.
- the pressure which exists in the supply conduit (5) is therefore insufficient to conduct the quantity of catalyst through the core shooting machine in as short a time as is desirable.
- a catalyst is contained in a pressurised vessel (11), which may be a simple gas bottle, and the pressurised vessel (11) is located on scales (12) in order to determine its contents.
- the pressurised vessel (11) can be heated by means of heater (13).
- a previously determined optimum quantity of catalyst is introduced via first valve (14) into pressure container (15) and first valve (14) is closed.
- Purging gas is supplied to the pressure container (15) through conduit (16) via second valve (17) at a pressure of 0.1 to 10 bar.
- Second valve (17) is then closed and third valve (18) is opened so as to introduce the mixture of catalyst and purging gas which is present in the pressure container (15) into supply conduit (19) and into the core shooting machine (not shown).
- Figure 3 shows similar apparatus to that shown in Figure 2 but the apparatus also has metering bellows (20) an additional fourth valve (21) located between first valve (14) and pressure container (15) and there is no heater.
- liquid catalyst in the pressurised vessel (11) is conducted through first valve (14) into the metering bellows (20) where the catalyst is transformed from the liquid to the gaseous state.
- First valve (14) is then closed and fourth valve (21) is opened, and the gaseous optimised quantity of catalyst is introduced into the pressure container (15), while the second valve (17) and the third valve (18) remain closed.
- the fourth valve (21) has been closed the second valve (17) is opened and purging air is introduced into pressure container (15).
- the third valve (18) is then opened and the mixture of catalyst and purging gas is introduced to a core shooting machine (not shown) via supply conduit (19).
