DESCRIPTION:
BRIEF SUMMARY
The present invention relates to dross processing systems and more particularly to dross presses and to press heads and dross pots for such presses.
Dross presses are known and comprise a press head which is hydraulically controlled to press dross in a dross pot. A known dross press is described in co-pending Patent Applications Nos. 9507605.5 and 9507606.3 to the present applicant.
A problem which occurs with dross when pressed in a dross pot is that a skull is produced which can be too large for further processing.
A further problem which arises with dross pressing is that when the dross is pressed the residue can block the hole in the bottom of the dross pot and this can result in a substantial loss of metal recovered from the dross.
The present invention has a first object to produce a skull which will readily break and for a second object to provide a dross pot which does not readily block.
According to the present invention there is provided a dross pot for a dross press, the dross pot comprising a generally conical shape and being provided with a plurality of outstanding ribs internal to the generally conical shape.
In a preferred embodiment four ribs are provided, each rib being equidistantly spaced within the generally conical dross pot.
In a further embodiment all four ribs may be joined together at the base of the dross pot and there are provided four drainage holes for molten metal formed between the four ribs. In this manner blockage of the drainage holes is avoided and the ribs provide guidance for the molten metal down the respective drainage holes.
In further preferred embodiments three or five ribs are provided but the number of ribs may be varied.
Preferably each rib is of an inverted V or half round cross-section.
Embodiments of the present invention will now be described, by way of example with reference to the accompanying drawings, in which:
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows a press head in accordance with the present invention;
FIG. 2 shows in side elevation a dross pot in accordance with a preferred embodiment of the present invention;
FIG. 3 shows a side elevational cross-section of the dross pot of FIG. 2;
FIG. 4 shows the dross pot of FIG. 2 in partial plan view;
FIG. 5 shows in cross-section an upstanding rib of the dross pot of FIG. 2; and
FIG. 6 shows in cross-section part of the wall section of the dross pot of FIG. 2.
With reference now to FIG. 1, the dross press head 10 comprises a generally conical shaped head 12 made from a suitable heat resistant metal. The head is provided with an upper plate 14 which is connected to the head 12 by, for example, bolts indicated at 16. The thickness of the walls of the head 12 and plate 14 may for example be 2 inches (50 mm) and the diameter of plate 14 may be 50 inches (1250 mm). The head is preferably provided with a reinforced or thickened central portion 18 which may be 5 inches (125 mm) in height.
Head 10 may therefore be of simple design and therefore will be robust and capable of withstanding temperature shocks more easily than a more complex design of head.
Head 10 may be provided with cooling, for example of the type exemplified in copending British Patent Application Nos. 9507605.5 and 9507606.3 to the same applicant.
The ribbed dross pot enables the head to be of a simple smooth sided design, for example conical pyramidal or even hemispherical. The use of a smooth sided head greatly improves the cooling effect of the head, especially when the head is provided with a forced cooling system. Thus, the dross is cooled more quickly and more efficiently thereby increasing the efficiency of the press.
The head 10 cooperates in known manner in the dross press with a dross pot 20 as shown in FIGS. 2 to 6.
The dross pot 20 comprises a generally conically shaped bowl 22 which is supported on two box section beams 24,26 (FIG. 3) with the assistance of four support buttresses 28,30,32 and 34.
Inside the conical bowl shaped dross pot 22 a plurality of upstanding ribs 36,38,40 and 42 are provided and these form, in the bottom
