A kind of chain transportation system of electrodeposit metals cathode plate
Technical field
Stripping system more particularly to a kind of electrodeposit metals cathode plate the present invention relates to a kind of electrodeposit metals cathode plate
Chain transportation system.
Background technology
In the industrial production of field of hydrometallurgy, common electrodeposition extraction method produces gold, silver, copper, zinc, nickel, cobalt from solution
Wait simple metal.In practice, by electrolysis make metal target (such as zinc) deposition in a cell cathode plate (cathode plate sheet as
Aluminium sheet) exposed surface on (for metal target is made to detach well with cathode plate, be unlikely to form a monoblock, usually by cathode plate
Both sides of the edge at wrapped up with rubber, make cathode plate both sides deposit metal be independent two parts).
As shown in Figure 1, the agent structure of cathode plate be aluminium sheet, including overhead traveling crane lift by crane cathode plate when lifting lug 21, electrolysis work
Upper edge 24, the insulation strip 25 of conductive rod 23, zinc metal sheet in the copperhead 22 of skill conduction, electrolysis process, the upper edge 24 of zinc metal sheet exist
Liquid level in electrolytic cell, insulation strip 25 ensure that the zine plate of tow sides is unlikely to be sticked together in growth course.
When deposited metal layer reaches certain thickness, plate is proposed from electrolytic cell with overhead traveling crane, using stripping Zn system or
Manually, the metal layer being deposited on cathode plate with cathode plate is removed in itself, cathode plate is cleaned after stripping, it will be cloudy
Pole plate hangs in electrolytic cell with overhead traveling crane and carries out electrodeposition again, recycles.
In the stripping Zn system, usually there are following sections:
First, system is received -- hang the cathode plate to be stripped come for receiving overhead traveling crane;
2nd, transport system-be used for will receive system cathode plate to be stripped conveying, pass sequentially through prestripping, main stripping, brush
The stations such as plate are removed and are scrubbed;
3rd, brushing system-generally comprise the equipment such as prestripping, main stripping, brush board is removed, for opening cathode plate
Mouth, stripping and scrub;
4th, plate system is taken, is removed for the cathode plate finished will be removed in transport system, and collects and overhead traveling crane is waited for hang
Return electrolytic cell;
5th, piling system, for the sheet metal stripped down from cathode plate is collected, stacking, weigh, coding simultaneously
It is transmitted to next procedure.
Transport system (above-mentioned second point) of the prior art, including:
(1) actuation techniques of chain:
The chain length of entire chain transport system is generally more than 20 meters, while need frequent start-stop again, and actuation techniques are extremely
It closes important, the response speed and control accuracy of chain is directly affected, in the prior art using two servo motors to chain
It is driven, the consistency of control is poor, while of high cost.
(2) chain detection and localization technology:
In the prior art, it is controlled using servo motor plus encoder, while is detected using encoder, but
It is to have accumulated error in operation, system in the process of running can not eliminate accumulated error, when error is excessive, so that influencing
During the operation of subsequent handling, system can not detect, and equipment damage can be caused to jeopardize safety.
(3) structure type of chain:
The structure type of chain directly determines the weight of chain, and the stationarity in operational process is driven so as to influence chain
Move the noise level in the type selecting, service life and operational process of motor.
(4) drive form of chain:
Existing procucts are both-end driving, i.e., respectively there are a motor totally two motors while drive chain fortune in left and right ends
Row, but existing product drives for servo motor, it is of high cost.
(5) the tensioning of the chain form:
Whether chain tension directly affects the service life and noise of chain in place.
For the prior art to be mechanically tensioned at one end, general is mostly the mode of jackscrew, is tensioned, but this
Tensioning mode is unstable to need artificial regular check, and amount of tension is determined completely by the experience of worker.
(6) structure and installation form of hook:
In the prior art, the only two long both ends of conductive rod 23 for tangling cathode plate of both sides carry cathode
Plate.But the drawbacks of this scheme, is cathode plate when moving, start and stop speed is fast, it is easy to occur in the direction of movement
Play is unfavorable for subsequently to the processing of cathode plate, is such as removed in stripping station, in most end station by cathode plate from this system
On the realizations of actions such as remove.
