Description

Shorting Frame The present invention relates to a shorting frame which may be used to electrically isolate a cell of an electrowinning plant.
Electrowinning plants typically comprise a large number of electrowinning cells, each of which contains metal (e.g. copper) in a solution together with a plurality of anodes and cathodes. An electrical current is passed between the anodes and cathodes, thereby causing metal to be extracted from the solution and deposited onto the cathodes.
It is conventional to connect cells of an electrowinning plant in series. A problem which may arise is that, since the cells are connected in series, switching off one of the cells will also switch off all of the other cells in the series. From time to time it may be desirable to switch off one or more of the cells without switching off the other cells in the series. For example, it may be necessary to clean a given cell or cells, but desirable to keep the other cells of the series in operation whilst cleaning is taking place. In order to allow a cell or cells to be switched off without switching off the series of cells, a shorting frame may be used. The shorting frame comprises busbars which are configured to form a conducting frame which can be used to electrically isolate a cell or cells, and thereby allow access to that cell or cells whilst allowing the remaining cells to continue to operate.
A conventional shorting frame has conducting rods on one side, the conducting rods being configured to establish electrical contact with cathodes of a cell that is adjacent to a cell or cells to be isolated. Conducting rods are also provided on an opposite side of the shorting frame, the conducing rods being configured to establish electrical contact with anodes of a cell that is adjacent to an opposite side of the cell or cells to be isolated. In some instances a conventional shorting frame may not provide effective * * electrical isolation of an electrowinning cell. ** I * . S *
It is an object of the present invention to provide a shorting frame which overcomes a * problem associated with prior art shorting frames. *
According to a first aspect of the invention there is provided a shorting frame for an electrowinning plant, the shorting frame comprising a conducting frame and a plurality of conducting rods which are connected to the conducting frame, wherein at least one of the conducting rods is configured such that it provides an electrical connection point which is inwardly displaced from the conducting frame, the inward displacement of the electrical connection point being greater than the inward displacement of the electrical connection point in a conventional shorting frame.
The conducting rod may include a portion which is oriented inwardly relative to the shorting frame.
The conducting rod may include a portion which is oriented downwardly when the shorting frame is in an operational orientation.
The portion of the conducting rod which is oriented inwardly and the portion of the conducting rod which is oriented downwardly may be connected, thereby forming an inverted Lshape.
The inwardly oriented portion of the conducting rod may be oriented horizontally when the shorting frame is in an operational orientation.
A lowermost surface of the conducting rod may be provided with a recess.
The recess may be configured to provide an electrical contact with a conducting bar of the electrowinning plant.
The conducting bar may be an inter-cell bar of the electrowinning plant.
According to a second aspect of the invention there is provided a shorting frame for an electrowinning plant, the shorting frame comprising a conducting frame and a plurality 1.... of conducting rods which are connected to the conducting frame, wherein at least one *IS.
* 20 of the conducting rods is configured such that in use it is in electrical contact with a * ***** * conducting bar of the electrowinning plant that connects electrode hanger bars of an electrowinning cell.
S.....
* The conducting bar of the electrowinning plant may connect cathode hanger bars of an electrowinning cell.
*..: 25 The conducting bar of the electrowinning plant may connect cathodes of an electrowinning cell with anodes of an adjacent electrowinning cell.
According to a third aspect of the invention, there is provided an electrowinning plant and a shorting frame, wherein the shorting frame comprises a conducting frame and a plurality of electrical contacts, at least one of the electrical contacts being configured such that it rests upon a conducting bar of the electrowinning plant which connects cathode hanger bars of an electrowinning cell.
The shorting frame may comprise at least one additional electrical contact which is configured such that it rests upon an anode hanger bar of the electrowinning plant.
According to a fourth aspect of the invention there is provided a method of shorting out an electrowinning cell of an electrowinning p'ant, the method comprising using a shorting frame to connect a conducting bar on one side of the electrowinning cell to anode hanger bars on an opposite side of the electrowinning cell.
Embodiments of the invention will now be described by way of example only, with reference to the accompanying figures, in which: Figure 1 is a view from above of a shorting frame which embodies the invention; Figure 2 is a partial cross-sectional view from one side of a contact of the shorting frame, together with part of the shorting frame in cross-section; Figure 3 is a cross-sectional view from one side of the shorting frame in operation in an electrowinning plant; Figure 4 is a view from one side of part of the shorting frame and part of the electrowinning plant; and Figure 5 is a view from one side of a different part of the shorting frame and part of the electrowinning plant. *S..
Figure 1 shows, viewed from above, a shorting frame according to an embodiment of : the invention. The shorting frame 2 comprises a conducting frame formed from four * rectangular busbars 4. Each rectangular busbar 4 is formed from two straight elongate ***SI* copper bars and two elongate copper bars with corners at either end, the copper bars being bolted together to form the four rectangles. Copper spacers are provided *. : 25 between adjacent busbars 4, thereby providing gaps between the busbars. The gaps * allow heat to radiate from the shorting frame 2 more efficiently than would be the case if the gaps were not present. The busbars 4 and spacers may be made from a conducting material other than copper.
A plurality of electrical contacts 10 are provided on one side 2a of the shorting frame 2 and on an opposite side 2b of the shorting frame. In Figure 1, sixty four contacts 10 are provided on each side of the shorting frame 2. However, any suitable number of contacts may be provided (for example seventy five contacts). The number of contacts may for example correspond with the number of cathodes in an electrowinning cell which is to be isolated. The contacts may for example be separated from one another by 100mm, or by any other suitable distance. The positions of the contacts 10 may be staggered on opposite sides of the shorting frame 2 (e.g. a contact on one side 2a of the shorting frame may be opposite a gap between contacts on the opposite side 2b of the shorting frame).
Figure 2 shows in cross-section viewed from one side an electrical contact 10. The electrical contact 10 comprises a conducting rod 12 which is held by two brackets 14a,b. The conducting rod 12 may for example be formed from copper, and the brackets 14a,b may for example be formed from stainless steel. Each bracket 14a,b is provided with an opening through which the conducting rod 12 is free to move upwards and downwards. A bush 16a,b, which may for example be formed from nylon, is provided in the opening of each bracket 14a,b to facilitate smooth movement of the conducting rod 12 through the bracket openings. A collar 18, which may for example be formed from stainless steel, is secured to the conducting rod 12, such that the collar moves with the conducting rod. A helical spring 20 is provided between the collar 18 and the uppermost bracket 14a. An upper end of the helical spring 20 pushes against the uppermost bush 16a, and a lowermost end of the helical spring pushes against the collar 18. The helical spring 20 resiliently biases the conducting rod 12 downwards, such that the collar 18 pushes against the lowermost bush 16b.
The brackets 14a,b are bolted to busbars 4 of the shorting frame by bolts 22, which may for example be formed from stainless steel. A flexible busbar 24 is bolted at one end to busbars 4 of the shorting frame, and is bolted at an opposite end to an upper end of the conducting rod 12. The conducting rod 12 includes a flattened upper portion 12a to which the flexible busbar 24 is bolted. The flexible busbar 24 provides an electrical contact between the conducting rod 12 and the busbars 4. The flexible busbar 24 may for example be formed from braided copper. The flexible busbar 24 *..: 30 may alternatively be formed from a plurality of laminations of copper which are formed into a flexible bar. A shroud (not shown) may be provided around the flexible busbar 24.
A lowermost portion 12b of the conducting rod 12, includes a portion 12c which is oriented inwardly relative to the shorting frame, and includes a portion 12d which is oriented downwardly (when the shorting frame is in an operational orientation). The inwardly oriented portion 12c and the downwardly oriented portion 12d are connected, thereby forming an inverted L shape. The inwardly oriented portion 12c and the downwardly oriented portion I 2d may be considered together to form a joggle.
In an alternative configuration of the conducting rod 12 (not illustrated), the conducting rod includes a portion which is angled inwardly and downwardly (when the shorting frame is in an operational orientation).
A lowermost surface of the conducting rod 12 is provided with a recess 26. In this embodiment the recess 26 comprises a groove with a substantially semi-circular profile. However, the recess 26 may have other shapes in other embodiments, or may be absent in other embodiments.
A central point of the lowermost surface of the conducting rod 12 is a distance d away from an inner surface of the conducting frame formed from the busbars 4. The distance d may for example be 95mm. The distance d may for example be greater than 60mm, and may for example be greater than 90mm.
Figure 3 shows in cross-section four electrowinning cells 30a-d of an electrowinning plant, together with the shorting frame 2 of figures 1 and 2. The shorting frame 2 is positioned such that the second and third electrowinning cells 30b,c are electrically isolated from the other electrowinning cells 30a,d by the shorting frame 2.
Each electrowinning cell 30a-d is provided with a plurality of anode hanger bars (e.g. ". sixty four anode hanger bars). For ease of illustration, only one anode hanger bar **..
32a-d is shown for each cell. Each anode hanger bar 32a-d is provided with a pair of brackets 34a-b from which an anode (not shown in Figure 3) may be hung such that it projects downwards into solution present in the electrowinning cells 30a-d.
**S S. * 25 Each electrowinning cell 30a-d is also provided with a plurality of cathode hanger bars (e.g. sixty four cathode hanger bars). For ease of illustration, only one cathode hanger bar 36a-d is shown for each cell. Each cathode hanger bar 36a-d is provided with a pair of brackets 38a-d from which a cathode may be hung such that it projects downwards into solution present in the electrowinning cells 30a-d.
Figure 4 shows in more detail part of an electrical contact 10 of the shorting frame, and upper ends of walls of adjacent electrowinning cells 30a-b. An insulator 40 rests upon upper ends of the walls of the cells 30a-b. The insulator 40, which may for example be formed from wood or plastic, is profiled with recesses which are configured to allow the insulator to receive various components. A first recess 42 holds a conducting bar 44 upon which anode hanger bars 32a of the first electrowinning cell 30a rest. The conducting bar 44, which may for example be formed from copper, ensures that the anode hanger bars 32a are eectricaUy connected to one another.
A second recess 46 of the insulator 40 holds a conducting bar 48 which is referred to hereafter as the inter-cell bar 48. The inter-cell bar 48 includes a first protruding portion 50 which extends upwardly along one side of the inter-cell bar, and a second protruding portion 52 which extends upwardly along an opposite side of the inter-cell bar. The first protruding portion 50 is configured to receive cathode hanger bars 36a of the first electrowinning cell 30a, and to be electrical contact with them. The second protruding portion 52 is configured to be in electrical contact with anode hanger bars 32b of the second electrowinning cell 30b, and be in electrical contact with them. The inter-cell bar 48 thus provides an electrical connection between the cathode hanger bars 36a of the first electrowinning cell 30a and the anode hanger bars 32b of the second electrowinning cell 30b.
A second insulator 54 rests on top of the inter-cell bar 48. The second insulator 54 includes a recess 56 which holds a conducting bar 58 upon which cathode hanger bars 36b of the second electrowinning cell 30b rest. The conducting bar 58, which may for example be formed from copper, ensures that the cathode hanger bars 36b are electrically connected to one another.
If the shorting frame 2 were not present, then electrical current would flow into the * anode hanger bar 32a of the first electrowinning cell 30a, into the associated anode * S....
* (not shown), through a solution provided in the first electrowinning cell, into a cathode (not shown), and from the cathode into the cathode hanger bar 36a of the first * electrowinning cell. The electrical current would then flow from the cathode hanger bar *....
* 36a through the inter-cell bar 48 to the anode hanger bar 32b of the second electrowinning cell 30b. The current would then flow through the anode hanger bar *:*. 32b to an anode, and from there into a solution in the second electrowinning cell 30b, etc. A contact 10 of the shorting frame 2 is shown in figure 4. A lowermost end of the conducting rod 12 of the contact 10 rests upon the first protruding portion 50 of the inter-cell bar 48. The recess 26 provided in the lowermost end of the conducing rod 12 receives an upper end of the first protruding portion 50 of the inter-cell bar 48. The recess 26 is shaped such that it provides a good electrical contact between the conducting rod 12 and the upper end of the first protruding portion 50 of the inter-cell bar 48.
The helical spring 20 (see Figure 2) resiliently biases the conducting rod 12 downwards, thereby pushing it against the inter-cell bar 48. A degree of compression of the helical spring 20 is provided by the weight of the shorting frame 2, thereby allowing movement of the conducting rods 12 such that they establish good electrical contact with the inter-cell bar 48.
With the shorting frame 2 is present, the current does not flow from the cathode hanger bar 36a of the first electrowinning cell through the inter-cell bar 48 to the anode hanger bar 32b of the second electrowinning cell. Instead, it flows from the cathode hanger bar 36a along the inter-cell bar 48 to the lowermost end 12b of the conducting rod 12.
The current then flows around the shorting frame 2 to a contact provided on an opposite side of the shorting frame.
Figure 5 shows the opposite side of the shorting frame 2, including a contact 10. The conducting rod 12 of the contact 10 rests upon the anode hanger bar 32d of the fourth electrowinnirig cell 30d. The helical spring (not shown) resiliently biases the conducting rod 12 downwards, thereby pushing it against the anode hanger bar 32d and helping to provide good electrical contact between them. The anode hanger bar 32d may for example have a flat uppermost surface, and the lowermost surface of the conducting rod 12 may include one or more flat portions. S...
Current flows from the shorting frame 2 through the conducting rod 12 to the anode hanger bar 32d of the fourth electrowinnirig cell 30d. The current thus bypasses the second and third electrowinning cells 30b,c, thereby allowing maintenance work to be performed on those electrowinning cells whilst allowing other electrowinning cells of the * S...
* * electrowinning plant to continue to operate.
In an alternative arrangement (not illustrated) the conducting rod rests upon the second *:*.; protruding portion 52 of the inter-cell bar 48.
As has been described above in relation to Figure 4, the lowermost end 12b of the conducting rod 12 is configured to contact the inter-cell bar 48. This differs from conventional shorting frames, where a conducting rod of the shorting frame is configured to contact a cathode hanger bar 36a. Since the conducting rod 12b of the embodiment of the invention is configured to contact the inter-cell bar 48 rather than the cathode hanger bar 36a, this means that it is not necessary for the cathode hanger bar 36a to have a conducting upper surface which may provide electrical contact to the conducting rod 12. Consequently, the cathode hanger bar 36a may include some form of coating on its upper surface (for example a stainless steel coating). The embodiment of the invention thus allows more flexibility in the structure of the cathode hanger bar 36a than would be the case if a prior art shorting frame were to be used.
In a conventional shorting frame, a conducting rod typically extends directly downwards (e.g. such that a central point of the lowermost surface of the conducting rod is 45mm away from an inner surface of the conducting frame). The conducting rod of a conventional shorting frame provides an electrical contact point which is on the cathode. The conducting rod of embodiments of the invention provides an electrical connection point which is inwardly displaced from the conducting frame, the inward displacement of the electrical connection point being greater than the inward displacement in a conventional shorting frame. Thus, the electrical contact point is on the inter-cell bar 46, which is inwardly displaced relative to the point where the conducting rod of a conventional shorting frame would contact the cathode hanger bar 36a.
Embodiments of the invention allow the shorting frame to be used in electrowinning plants in which an uppermost surface of cathode hanger bars is not conductive.
The inwardly oriented portion 12c of the conducting rod 12 allows the conducting rod to rest upon the inter-cell bar 48, whilst maintaining a sufficiently wide inner perimeter of * **.

* S electrowinning cell. This advantage is also provided by the alternative configuration of the conducting rod (not illustrated) in which the conducting rod includes a portion which is angled inwardly and downwardly (when the shorting frame is in an operational orientation). S. *I
Although the figures show a shorting frame 2 which is configured to bypass two * *: electrowinning cells, the shorting frame may be modified such that it bypasses only one electrowinning cell, three electrowinning cells, or any other suitable number of electrowinning cells.
Although figure 4 shows the shorting frame 2 in electrical contact with an inter-cell bar 46 of an electrowinning plant, the shorting frame may alternatively be in electrical contact with an end-cell bar of an electrowinning plant. An end-cell bar is a conducting bar which connects cathodes of a first cell of an electrowinning plant. The inter-cell bar and the end-cell bar may be considered to be examples of conducting bars.
The shorting frame may be used in an electrowinning plant which is configured to extract copper, cobalt, nickel, zinc or any other suitable metal from a solution. S... * * 55.
