For the improved current sense and management system of potroom

Technical field

The present invention relates to changing for metallurgical system (particularly electrometallurgy system) and electrolytic cell and/or tank house operation conditions Enter.

The present invention can be specifically applicable to real-time monitoring and constitute metal deposition groove or refining cell or have Each negative electrode or anode of other electrolytic cells of parallel pole.

Background technology

Metal extraction process such as to the extraction process of copper generally includes electrolytic deposition or electrorefining recycling step.Close In these steps, the performance that it provides real-time monitoring each metallic plate is to realize the advantage of the optimum performance of potroom.

In electrolysis process, in the case where causing on surface metal growth uneven due to physical imperfection if electrode Alignment is not arranged to, then may be short-circuited, this is probably the result of following operational issue：Such as impurity, higher than acceptable Cathode current, electrolyte in particulate, the electrode that damages or electrodeposit peel off and then contact neighbouring electrode, and other Problem.In the case of there is bad electrical contact between male or female and its current source, it is also possible to which low current situation occurs, from And cause the system effectiveness to reduce.Both of which may cause low-quality product, or such as the situation one of copper electrolyzing refining Sample can not reach desired purity, wherein, these situations also can result in electric current and power-efficient reduction, and this may reduce workshop Yield and increase cost.In this context, the electric current of the electrode that control passes through each electrolysis cells uses above-mentioned mistake for improving The technique of the system of journey, product and efficiency are critically important.

The problem of each electrolysis cells of monitoring is described in patent CL 44,909 (J.Garc é s Baron).It is special at this In profit, the monitoring system of the electric current of each negative electrode by constituting electrode group is described, such monitoring system includes being connected to The multiple of communicator close to current sensor, and wherein, such communicator with there are graphic user interface apparatus Processing and control element (PCE) communicates.Such proximity transducer is close by the magnetic flux generated through electric current through electrode by measuring The intensity of degree measures this through electric current.

Patent US 7,445,696 (Eugene You et al.) is also described for electrodeposition groove and refining cell The general principle that current sensing system is based on, and describe the theory side for compensating the magnetic field that adjacent electrode is generated Method.The patent does not describe the basic practical aspect of structure sensor bar, including bar is sealed device, avoid electrical noise Device, consider the device of actual alignment, the geometry of the sensor strip inside many tank systems limited Device and the device of such bar is supported in groove.Specifically, because when electrode is lowered by into groove, electrode is easy to hit Sensing system is hit, is caused sensing system to damage and hinder and effectively electrode is loaded into groove, thus prior art The presence of current sensing system may cause to be difficult to remove/replacement electrode in groove.Patent CL 44,909 and US 7,445,696 All do not solve the device of the integraty due to there is sensing system or for keeping sensor and cause electrode in groove The problem that movement is obstructed.May be provided for damaging sensing in itself for carrying the suspension hook of negative electrode and anode and strengthening back electrode hook The device of device system.US 7,445,969 also describes the method for overcoming the interference from adjacent electrode.Due in practice In seldom there are " preferable " theoretical situations, thus such system does not produce the reliable measurements for the electric current by electrode. Therefore, the art methods based on theoretical calculation do not cater to complementary field contribution.In addition, the solution party for proposing in the prior art Case does not account for the external action of measurement, and the such as operation conditions on magnetic field and measured electric current both of which produce the temperature of influence Degree.

In addition, the environment very severe in electrodeposition groove and refining cell.This is included with the electrolysis of usual highly acidity The chemical environment of matter, the acid droplet being present in the air space above electrolyte and possible halogen.It is serious as this , the physical environment with the frequent technique for removing and replacing electrode provides many damage sensors and sensor hinders The chance of electrode movement.For the environment not robust, this will cause frequently failure to version described in the prior.

Moist and chemical corrosivity environment above groove electrolyte needs the sensor must to be fully sealed in housing It is internal.As additional limitation, in many tank systems, because the sectional thickness impeded electrode of the bar with circular section is by under Be down to when in groove the path of electrode and electrode suspension hook can be lowered to below the head bar of electrode with by head bar come The path of impeded electrode suspension hook when lifting electrode, so such bar would prove unsuitable for below electrode head bar.Therefore, it is desirable to non- Circular section, because it is more practical and allow sensor to be placed closer to head bar to improve the degree of accuracy of sensor reading. Prior art does not mention this problem.

Thus, sealed in the absence of for the non-circular portion in the way of to be suitable for this application to non-circular profiles pipe Clearly defined prior art.Available known standard method (such as flange and thread ending cover) is for not rounded in this area Shape section is geometrically forbidden.Due to the minimum radius bend (tight being likely to be present in the turning of non-circular profiles pipe Radius bends), so the inner sealing method of such as O-ring is unpractiaca.Applicant has attempted being glued in the end of pipe Epoxy resin and engagement plug are closed, but because the thermal dilation difference being understood between grafting material and tube shell have failed.

On the operation in potroom, the harvest cycle in electrolytic deposition workshop or electrolytic refining plant (also referred to as takes off The film cycle) management generally recognized using schedules write or computer drives now need harvest which groove.This The system of sample is necessarily dependent on the computer recording that when should harvest groove that is paper or being manually entered.Desirably, it is known that The accurate deposition period of specified channel enables to accurately determine current efficiency, this software systems for needing customization and operator's It is strict to record to ensure that data are correct.Can in time know that the electric current in tank house sets when to change and according to the past Ampere-hour come to adjust sedimentation time be also valuable, but this needs to carry out extra calculating to each groove.In addition, There is human error to cause incorrect record data and not in the case of results groove in the range of the acceptable time period, then may be used Uncoordinated cathode weight, poor morphology, short circuit, anode can be caused to damage and current efficiency reduction.

In the case where workshop has automatic hoisting machine, these cranes are able to record that the precise time for harvesting groove, but It is that such system expensive and most of tank houses do not have these cranes.

Therefore, invention described in this application is intended to overcome by providing reliable current measurement one of prior art Or more above mentioned problem, the reliable current measurement is provided by the reliable solution of hardware, enabling optimization with Its related technique.

According to the implementation method of the method, in a preferred embodiment, pretreatment unit (6) receives number from sensor unit Correction is performed according to and to data-signal, is transmitted and is provided by the optimum signal of data communication channel to subsequent cell to provide Correction to current measurement caused by the influence by external variable, can perform the influence to external variable based on magnetic fluctuation Above-mentioned compensation.

May need to be compensated using shift step several in magnetic field sensor, amplifier, reference voltage and digital-to-analogue conversion Individual possible change.These changes are probably due to the geometry cloth of power supply, stray electrical current, earth's magnetic field, manufacture and location tolerance, groove Put, the magnetic field from the electrode current in adjacent slot, bow strip magnetic field between groove, misalignment electrode, the influence of bending head bar and Caused by other influences.

Prior art includes how description carries out the calculating of magnetic field correction based on theory to adjacent electrode and groove.It is preferable to carry out Mode is related to such calculating known in the art.It will be appreciated by those skilled in the art that the parameter for calculating will be with each Individual cavity feature and change.In practice, it is necessary to be modeled to groove and calculate adjustment.

Other sources of change may be caused, and to be that electrode is not always placed (by crane) complete on groove busbar Correct horizontal level.If electrode is not in the surface of sensor, will be less than electrode to the contribution of the field of sensor should The contribution for being given.In a preferred embodiment, in the absence of single sensor (to), and there is magnetic field sensor or magnetic field sensor To linear array.Output from these sensors can be compared (possible after correction with highest reading to find For the contribution higher from adjacent electrode current) sensor, it can be assumed that the horizontal level of highest reading and electrode It is corresponding.The cognition not only can be used to the reading of the reduction of the field of the sensor of compensating electrode itself, and more importantly may be used For compensating the contribution of the change to the field measured by adjacent sensors.

Then, by measured electric current and lower threshold electric current I_minWith upper limit threshold electric current I_maxIt is compared.At one In implementation method, we can pre-build the I of whole system_minAnd I_max.In another embodiment, we can be dynamically Adjust these values.If for example, occurring short circuit in groove, the major part of cell current will flow through short circuit, and by other electricity The electric current of pole will be less than nominal value.If we have pre-build very sensitive threshold value, the short circuit in an electrode may One or more other electrodes in groove are caused to be wrongly classified as loose contact.But if we dynamically count again Minimum threshold is calculated, this will not occur.The change that rectifier current can also be based on manually or automatically adjusts these threshold values I_minAnd I_max。

Find out in one embodiment, ECM bars are positioned in the anode head to the anode connection of the main ICCB sides of groove The lower section of portion's bar.It may be preferred that geometry provides shadow of the anode current bigger to the influence in magnetic field than negative electrode to magnetic field Ring.In this embodiment, short circuit and loose contact are detected rather than cathode current by anode current.

In this sense, above-mentioned implementation method of the invention and following feature include and the function of metallurgical system, suitable The related various improved realization of Ying Xing, control and/or man-machine interface, wherein, these systems are preferably electrometallurgy system, all Such as electrorefining or electrowinning systems.In addition, the management that such improvement can apply to the electric current wherein by electrode is The different types of system of the key factor in system operatio and performance.

Therefore, in the preferred embodiment of the application, with for measuring for example, by electrolytic cell or tank house Electrode or multiple electrodes electric current current measuring device (such as Hall effect transducer) electrometallurgy system in realize on State improvement.On this point, these improvement are intended to optimize both performance and operation of at least one electrode, such as optimization stream Through the measurement of the electric current of at least one electrode.

Following part defines and the system, equipment introduced to realize these to improve and/or device is related changes Enter.For illustration purposes only, part below divides main improvement according to the main region clashed into, it is important that remember big In most cases improve related to more than one specific area.Therefore, description below should not be considered as to by herein The limitation of the improved type of described various systems, equipment and/or device introducing.In addition, pointing out for correlation is following Improving can be applied to metallurgical system either individually or as its any possible combination.

Function is improved

As already mentioned, function is improved and is intended to optimize its operation by maximizing the reliability of metallurgical system, and And thus it is intended to the final production of the system.

Electrode alignment position and misalignment

As noted earlier, in some tank houses or groove, the system for being positioned at anode and negative electrode in groove (rises Heavy-duty machine, groove adjunct, spacing block) may not cause that these electrodes are placed at identical position every time.That is, electrode It is not physically to be positioned by groove adjunct or similar devices.Therefore, if the change that electrode is placed is significant, for magnetic survey The change is measured, is probably suitable with least one or more magnetic field sensor.Then, by analyte sensors institute body The magnetic field tested, can estimate most probable skew of the electrode head bar away from its nominal position.Therefore, detected by particular sensor To any offset marker electric current for meaning in corresponding head bar have to the field that adjacent head bar is experienced it is slightly different Influence, it means that current measurement may be affected.Thus, if it is above mentioned skew be it is known (or at least by Estimate), then the algorithm that other people describe of the prior art can be changed using the knowledge and is better compensated for due to phase The field that electric current in adjacent electrode is produced.

The degree of misalignment can also be reported as the measurement that slot shell operator uses.

Double-contact systematic survey

In simplest groove, anode is connected to the side of groove, and (without loss of generality, the side can be referred to as the right side of groove Hand side) on busbar, negative electrode is connected to the busbar on another (left hand) side of groove.The left-hand end of anode head bar is exhausted Edge, flow through the part from without electric current.This means when measure negative electrode head bar electric current when, the only shadow seen by sensor That rings magnetic field flows through electric current because cathode current causes.

However, in some grooves of commonly known as double-contact groove, each electrode head bar can be connected on both sides. Although anode is still from right-hand side " feed ", the left-hand side of all anodes by also sometimes referred to as " balanced device bar " anode " balance strip " is connected.Similarly, the right-hand side of all negative electrode head bars can also be connected to negative electrode balance strip.If given There is bad connection between anode and main anode busbar, then electric current is by first flowing through other anode head bars, then flowing through The anode still can be flow in the head bar of the given anode of anode balance strip and then inflow.This is equally applicable to the moon Pole.Described in United States Patent (USP) 7,993,501 (Freeport McMoRan Corporation) and United States Patent (USP) 7,854,825 Be incorporated herein for entire contents by quoting by double-contact system, the disclosure of which.

In the case of using double-contact system, the magnetic field generated near negative electrode head bar not only can correspond to those heads Electric current in portion's bar, and it is also can correspond to the electric current in anode head portion bar.

Then, in the case of using double-contact system, other sensor can be positioned to straight with anode head bar Connect alignment (in below or above).Using slightly more complex adjacent electrode backoff algorithm, this will make it possible to measure cathode taps Electric current in both portion's bar and anode head bar.Being worth noting is, for the purpose of calibration, anode head bar (in balance strip side) In the summation of electric current will be zero, i.e. electric current will enter balance strip from some anode head bars, then will leave balance strip and enter In entering other anode head bars.

Contribute to two aspects using the sensor being aligned with anode：A () can obtain the electric current in negative electrode head bar More accurately estimate, this is the most useful amount of operation；And the estimation of (b) anode head bar balance strip electric current can help recognize There is bad connection in the where between anode and main groove between bow strip.Thus, EMC designs make it possible to measurement by balance The electric current of the adjacent electrode on bar to correct other anode balanced balanced current magnetic field, and there is provided the CURRENT DISTRIBUTION in assessment groove The method of result.

Voltage measurement

Another improvement that the application is realized is related to the multiple voltages at each point of the circuit along electrolytic cell/workshop to survey Amount, wherein, it is mounted with voltage measuring apparatus in electrolytic cell/workshop.

Including trunk busbar (trunk bus bar), trunk conflux rising head (trunk bus risers) each Point and the voltage measurement being connected at the difference of the length of bow strip along between the groove on different bow strips in electrolytic circuit Probe makes it possible to monitor each groove, and is thus able to different voltage drops of the monitoring by circuit.Due to voltage can be determined Drop and corresponding power consumption, so this help improves the management of whole circuit.So as to, as discussed further below, tank voltage drop The method as assessment deposition quality can be combined with other measurements (such as temperature and density metal).The accurate measurements of tank voltage Overall performance (such as titanium mixed-metal oxides (MMO) anode performance) for monitoring anode is also critically important.With conventional lead base Anode is compared, and titanium MMO anodes are used because of the requirement of its low-voltage.Tank voltage change can represent the painting on the anode in groove The problem of layer.During attended operation, groove can generate voltage by the reverse plating of metal, if be not detected by this existing As can then cause the permanent damages of the performance to titanium MMO anodes.

The adjust automatically of short circuit/loose contact threshold value

In system simplest form, once electric current exceedes particular static predetermined threshold, then system can be by negative electrode point Class is in " short circuit " situation.However, dynamically calculating such (on short circuit and loose contact) threshold using various parameters Value is more preferable.

During harvest cycle, can be from the electrode of groove removal 1/3.This might mean that other electrodes are contemplated that and sees 50% electric current (it is assumed that rectifier overall electric current keeps constant) higher.This means short-circuit threshold value should be increased, so as to this just Reason shape does not produce the short circuit instruction of vacation.

Similarly, if rectifier current is reduced, each negative electrode is it should be appreciated that less electric current.Even if distribution is perfect (that is, without short circuit or loose contact), depending on threshold value, this is likely to cause the classification of loose contact.

3rd, if there is short circuit in groove, the ratio big than usual of total cell current will flow through the short circuit, remaining less Electric current flow through other.This may mean that in other electrodes some be classified as loose contact, even if their actually names Adopted Shangdi operates and does not exist operating trouble in those electrodes.

Then, according to the application, the threshold value of short circuit and loose contact can be calculated by computing device, as (a) total groove Whether electric current, (b) have the function of short circuit or loose contact due to harvesting at other in losing electrode and (c) groove.Cause This, the application sets up dynamic threshold according to above-mentioned parameter, and due to Continuous plus threshold value, described this improves the reliability of system administration Property.

Recognize the mode detection of short circuit/loose contact

Compare (even if the threshold value may not be static number) with the instantaneous of threshold value as cathode current, it has been described that cloudy Pole is classified as in short-circuit condition.

If however, negative electrode have on busbar contact resistance somewhat high or away from adjacent anode be located at farther out away from From place, then it may have somewhat low electric current, but still produce short circuit.By observing over time a series of of fully increase Current measurement, or even can conclude that negative electrode just enters short-circuit condition before negative electrode reaches actual short threshold value.

Additionally, when short circuit is formed, short circuit may disappear and then re-form, and this is early stage short-circuit life cycle Cause oscillating current.The implementation method of ECM bars may be configured to detect that such vibration is categorized as into short circuit with by negative electrode State.

Therefore, the application is provided with to provide the mode detection apparatus of reliable short circuit/loose contact algorithm for estimating, this Help improves system administration.

Prevent the protection device of physical damage and destruction electrode movement

Present invention introduces significantly improve including：It is incorporated to the protection device or multiple protections installed along the length of ECM bars Device, to protect ECM bars from mechanical failure and avoid damage to normal electrode movement, wherein, ECM bars include current measurement Device.In this context, Fig. 3 and Fig. 4 illustrate in detail the protection device that one kind is designed to deflector (11), wherein, its Design helps to avoid damaging ECM bars (2) and being acted during normal electrolytic cell crane operation being dropped with electrode Push electrode to its correct position (such as during electrode (3,4) are introduced) when low, this may cause by colliding with electrode Damage ECM bars (2).It is therefore important that emphasize, limiting protector does not set the deflector design described in Fig. 3 and Fig. 4 Meter, it is possible to use ceiling is from collision and any kind of design of other types of physical damage.

In addition, protection device can be fixed to supporting arrangement, bar or be directly fixed to the channel parts of arbitrary standards.This Including but not limited to groove adjunct, cell wall or cover plate.

As discussed previously, prior art is not described for overcoming the movement of interference electrode and avoiding setting for bar damage Meter.The robustness of environment very severe and design in groove is very crucial.Ensure not destroy normal electrode movement and ECM bars The identifying device do not damaged is to include the supporting arrangement of deflector.Electrode is being reduced using respective load with crane system reduction Rate reduction electrode when, deflector allow for manage electrode weight.Load must be not transferred to sensor strip, but must The angle on the surface that must be absorbed and pass through deflector by being transferred to cell wall is minimized.Deflector must also protect branch Hold the support of ECM bars.

End part seal is arranged

Electronic unit can be encapsulated in and enable material internal of the bar without external shell.This encapsulating material can Constituted with by acidproof epoxy resin or other encapsulating materials.

As shown in figure 5, it is of the invention further improvement is that the one or both ends of ECM bars (2) include sealing device, its In, the sealing device provides the protection of the equipment being pointed in this.In this sense, according to Fig. 8, sealing device includes The fastener (15) of backboard (12), pad (13), end cap (14) and similar screw or any other attached peripheral device.

Thus, sealing arrangement of the invention is carried by the way that backboard (12), pad (13) and end cap (14) are gathered together It is sandwiched between backboard and end cap for the sealing of the one or both ends of sensor strip, thus pad.Afterwards, fastener (15) is wide During loose ground is thread through end cap, pad and penetrates backboard, seal is assembled into.The seal assembly be inserted into bar (2) or In its correct position in housing.Finally, fastener is tightened to reduce the distance between end cap and backboard, and this causes pad Thickness reduce.Due to Poisson's ratio, this causes the width of pad and height increase.This increase of size generates seal assembly Sealing needed for and the inwall of bar between.

The major advantage that end part seal arrangement is provided in the one or both ends of ECM bars be it so that bar can be sealed with Protection internal part, for example prevent electrolyte contact the electronic installation inside the bar or may damage the part it is any its Its things.In this sense, end part seal arrangement allows electronic installation to slip into bar, sealing strip and the master to/from bar Cable is covered by cable seal draws.

In addition, if needing, sealing arrangement can also be removed for being repaired.

This encapsulating method can be used for arbitrary section (as an example including square, circular, rectangle and angled ) bar.

The design of ECM bars needs the inside of bar to have without prejudice to electronic installation and supports the section in bearing part insertion bar. Second limitation of the section of bar is that its needs is narrow as much as possible is moveable into and out groove holding simultaneously to avoid interference crane/electrode With electrode head bar closely.The two constraints eliminate using flange or threaded fittings to provide confrontation severe operation ring Border and the sealing of the electronic installation being included in ECM bars.During due to welding procedure produce heat and during the technique The potential damage of the electronic installation to being accommodated in bar, is also unpractical using the plate of the end for being welded on bar.

Per central location or controller multiple ECM bars

Another improvement includes adjusting each communication and central server between using controller equiment.For example, in The communication that centre server can be carried out between radio communication, but controller and ECM bars with controller can be wired.This meaning , in another embodiment, can be by the shared single controller equipment of several ECM bars.In this context, controller equiment There can be separate communication bus to be communicated with from different ECM bars, or all can share single bus.

If such connection topological structure and agreement are suitable to workshop, central server can directly be carried out with ECM bars Communication is without any middle controller.

CURRENT DISTRIBUTION is measured

In one embodiment, there may be two ECM bars in each electrolytic cell, wherein, the bar can be specific Be positioned on the opposite side of groove.The purpose of present embodiment is to enable to measure the cathode current on cathode contacts side On (and anode balanced balanced current, in the case of double-contact system) and the opposite side of groove anode current (and negative electrode balanced balanced current, In the case of using double-contact system).Thus, the improvement makes it possible to all inflow currents of the measurement by corresponding electrolytic cell It is distributed with flowing out electric current and obtaining the total current in groove.The uniformity of CURRENT DISTRIBUTION be for the quality metric of groove performance, this Because uniform electric current will cause the equal deposition on each negative electrode, this makes deposition weight consistency, deposition surface form most Bigization, minimizes short-circuit trend and maximizes current efficiency.

Concentration and other sensors

According to another improvement, ECM bars of the invention consider to include the part of concentration and other sensors as ECM systems Possibility.In this sense, ECM bars can merge temperature in specified channel, density metal, electrolyte flow or level, The instrument readings of additive concentration, electrical conductivity etc..

Measurement in a closed series value with determine be electrolysed performance quality or amount of electrolyte

Tank voltage increases with the total cathode current in groove.Tank voltage also groove temperature, electrolyte component and addition The influence of agent dose rate, electrode spacing and anode use time/state/type.If these parameters are in target level, groove Relation between voltage and electric current is predictable, and can by bench-scale testing for any specific tank house come most Good determination relation.All show that channel-shaped condition is not optimal with any deviation of the projected relationship, and solution should be taken steps to Certainly.ECM systematic surveys total cell current and tank voltage, and it is used as measuring for quality.If surveyed by ECM systems Arbitrary parameter (such as temperature, concentration) in amount other parameters, then ECM systems offer can be provided cause than optimal The definition of the possibility problem of the performance of poor performance.

The estimation of the current efficiency and Current compliance of each electrode

Due to ECM systematic surveys electric current flowing and the harvest time of each electrode is detected, thus combined after harvesting The weighing system that (and before possibility) is weighed to each negative electrode, ECM systems can calculate the current efficiency of each negative electrode. It can whether to determine to have consistent trend for the position current efficiency, (this can be with the electrode position of each in tracking groove Represent adjacent anode problem), or rfid system (or other negative electrode identifying systems) is combined, ECM systems can be with determination trend No is due to the problem of particular cathode plate.In less complex mode, system can track the electric current flowing of each electrode position And whether substantially to determine from a cycle to next cycle trend, or (have in place for specific negative electrode Have RFID or other negative electrode identifying systems) with the presence or absence of can represent special electrodes problem electric current trend.
