Definitions

the invention relates to a melting container, in particular a melting crucible, which has an inner space delimited by a wall region and a bottom region for receiving melting material, the bottom region of the melting container having a drain opening which can be closed by a closure element of a closure system.
Such a melting tank is known.
the drain opening of the melting container is arranged centered in the middle of the bottom.
the closure element namely a closure rod, which closes this discharge opening during melting of the material to be melted, lies in the central axis of the cylindrical crucible.
This object is achieved in that the drain opening of the bottom region of the melting tank is arranged off-center.
the inventive arrangement of the drain opening of the bottom region of the melting container according to the invention off-center and in particular close to the wall region of the melting container advantageously means that the closure element closing the drain opening, in particular a locking rod, can also be guided close to the wall, so that it can be filled filling cross-section available from melting material is significantly enlarged in an advantageous manner. Loading the melting crucible with the melting material can thus be carried out more easily and, above all, faster, since larger feed devices which receive the melting material can be used.
Another advantage of the construction according to the invention is that the mechanism of the closure system required for moving the closure element advantageously blocks only an extremely small part of the filling opening of the melting container.
An advantageous development of the invention provides that the bottom area in the vicinity of the discharge opening of the melting tank drops in at least two steps towards the discharge opening.
Such a procedure has the advantage that even with an asymmetrically arranged drain opening in the bottom region of the melting tank according to the invention, it is reliable and above all essentially complete emptying of the liquefied melt contained therein is ensured. This is of great importance in particular when melting expensive precious metals, since due to the high material costs it must be ensured that no melted precious metal remains in the melting container after the melting process.
a further advantageous development of the invention provides that the bottom contour of the melting container according to the invention, which has at least two steps descending towards the outflow opening, is formed in that in half the bottom region of the melting container according to the invention, in which the outflow opening is located, a corresponding number of depressions in the Floor area are provided.
Such a design has the advantage that the design of the floor area according to the invention can also be achieved without the use of special tools.
the melting container 1 shown in FIGS. 1 to 3 is essentially divided into a wall area 2, the outer surface of which is in thermal contact with a melting device 10, which is not shown in detail in the figures, and a bottom area 3.
a drain opening 5 of the bottom region 3 of the melting container 1 - which will be described in more detail below - can be closed by a closure element which can be moved up and down, in particular a locking rod 6 of a closure system 20, in the melting container 1 described now no longer - as in the known ones Melting containers is the case - in the area of the central axis M, but offset by a distance d from the central axis M, that is to say is arranged off-center. It is particularly advantageous here if the drain opening 5 of the base region 3 of the melting container 1 is arranged close to the wall region 2 of the melting container 1.
the drain opening 5 of the base region 3 of the melting container 1 is arranged outwards by approximately one third of the radius R of the preferably cylindrical melting container 1, that is to say offset to the wall region 2 on the right in FIG.
this filling cross section is increased in the radial direction by approximately one third of the radius R of the melting vessel 1.
Larger feed containers and feed devices can advantageously be used for the melting material to be introduced into the melting container 1, so that significantly more melting material per unit time can be introduced into the interior 1 'of the melting container 1 via the filling opening 8 than with one during each filling operation known container of this type is the case.
the melting container 100 shown in FIGS. 4 to 6 differs with regard to the arrangement of the sealing rod 6 from the melting container 1 shown in FIG. 1 in that the drain opening 5 of the base region 3 and thus the sealing rod 6 are even more similar to those on the right in FIG Wall area 2 is arranged approximately, which advantageously results in a further enlargement of the effective filling cross section of the filling opening 8 of the melting container 100.
the person skilled in the art can easily see from the above embodiment that, in principle, the drain opening 5 can be approximated to the wall area 2 to such an extent that a correct up and down movement of the locking rod 6 of the locking system 20 is still guaranteed.
FIGS. 1 and 4 differ in addition to the arrangement of the drain opening 5 of the floor area 3 and also in the design of the floor area 3 itself, which is shown in detail in FIGS. 2 and 3 or 5 and 6.
the bottom region 3 is designed to fall off from all sides towards the drain opening 5, in such a way that the one shown in FIG 1 or 4 left part of the base region 3 of the melting container 1, 100 - as in the known melting containers - falls in a known manner from the left wall region 2 via a slope 11 towards the center M, but now in the case of the one in FIGS.
the bottom area 3 widens a funnel-shaped depression 11a, in which one or two depressions 12 or 13a, 13b can be provided, so that the bottom area 3 of seen right to left is carried out at least in two stages.
Such a design of the bottom region 3 of the melting tank 1, 100 has the advantage that the described contour of the bottom region 3 is also particularly simple, i.e. without special tools, can be formed if - as in the melting container 100 - the drain opening 5 of the bottom region 3 is arranged close to the wall region 2 of the melting container 100.
a lifting device is used to move the locking element, in particular the locking rod 6, of the locking system 20, which essentially consists of a boom 22 which can be moved up and down by a lifting mechanism 21, the horizontal bar 22a of which engages the upper end 6 'of the locking rod 6 and its vertical Beam 22b is guided in a receiving bore 23.
