Description

Stripping systems for electrodeposited metals

technical field

The invention relates to the field of hydrometallurgy electrowinning equipment, in particular to a stripping system for electrodeposited metal, which is used for stripping metal deposited on a cathode plate.

Background technique

In the industrial production in the field of hydrometallurgy, electrolytic extraction is commonly used to prepare pure metals such as gold, silver, copper, zinc, nickel, and cobalt from solutions. In practice, the target metal (such as zinc) is deposited on the exposed surface of the cathode plate (the cathode plate itself is an aluminum plate) in the electrolytic cell by electrolysis (in order to separate the target metal from the cathode plate so as not to form a single piece, usually Wrap the edges of both sides of the cathode plate with rubber, so that the metal deposited on both sides of the cathode plate is separated into two parts. The structure of the cathode plate is shown in Figure 1, wherein, the number 21 is the lifting lug when the crane lifts the cathode plate, and 22 is the electrolytic solution. The conductive rod in the process, the number 23 is an insulator, the function is to ensure that zinc does not deposit here, which is beneficial to the pre-opening of the zinc sheet, and the number 24 is the upper edge of the zinc sheet, that is, the liquid level in the electrolytic tank, and the number is 25 is an insulating strip, which ensures that the zinc plates on both sides will not stick together during the deposition process). When the deposited metal layer reaches a certain thickness, use a crane to lift the cathode plate out of the electrolytic cell, and peel off the metal layer deposited on the cathode plate from the cathode plate itself. After cleaning the cathode plate, use the crane to lift the cathode plate again Hang it into the electrolyzer and recycle it. Due to the technical reasons in our country, the impurities in the target metal will be higher than those in foreign countries (especially fluorine and chlorine), which will cause the deposited target metal layer to be firmly bonded to the cathode plate itself. Manual or traditional cathode stripping is used. Machine stripping is very difficult.

At present, there are two foreign manufacturers in this field with this stripping system technology: Paul Wurth in Luxembourg; Mitsui in Japan. Among them, Paul Wurth’s zinc stripping process is as follows: 1. The stripping knife is opened, the cathode plate is lifted to the designated position by the lifting mechanism, and at the same time there is a zinc-connecting bucket with a controllable opening, and the zinc-connecting bucket is also lifted below the cathode plate A certain height; 2. The main stripping knife is closed and kept still. The cathode plate continues to be lifted until the zinc sheet is completely stripped. Bucket; 3. The main stripping knife is opened, the cathode plate and the zinc receiving bucket fall at the same time, after falling in place, the door at the bottom of the zinc receiving bucket is opened, the zinc flakes fall, and enter the zinc flake receiving and stacking process.

No matter which manufacturer's stripping system is basically composed of the driving device for the main stripping knife to move downward relative to the cathode plate, the limit device for the main stripping knife to move downward relative to the cathode plate, the device for closing and opening the main stripping knife, the knife frame and a stripping knife; but the inventors have found that the existing stripping system has at least the following problems: as in the Paul Wurth scheme, the device for controlling the opening and closing of the scraper uses a cylinder on both sides of the scraper to control the opening and closing of the scraper. In this case, it is difficult to guarantee the synchronization of the opening and closing of the scrapers on both sides; in addition, there is no adjustment device for the angle between the knife and the knife holder relative to the cathode plate. It is very high, and after working continuously for a period of time at the same time, the cutter and the cutter holder will inevitably be deformed, and the cathode plate will be damaged when peeling off. In Mitsui's plan, the device for controlling the opening and closing of the main stripping knife is to install two oil cylinders on the frame, one on each side of the main stripping knife, one end of the oil cylinder is fixed on the frame, and the other end is connected with a rectangular steel. The knife rest is also welded by rectangular steel, and the rectangular steel at one end of the oil cylinder is sleeved outside the rectangular steel of the knife rest, and can slide in the rectangular steel at one end of the oil cylinder. The opening and closing of the main stripping knife is controlled by the expansion and contraction of the oil cylinder. Because the rectangular steel length of the knife holder is longer, it slides in the rectangular tube of the oil cylinder. After the expansion and contraction of the oil cylinder is completed, the position of the rectangular steel on the oil cylinder is fixed, and the rectangular steel of the knife holder slides inside it. Because the length of the knife holder is long, the deformation of the rectangular steel is inevitable, which causes the stripping knife at the lower end of the knife holder to move with the knife. The deformation and irregular movement of the rectangular steel of the frame may scratch the cathode plate; the tool adjustment device in this scheme is to install a spring between the above two sliding rectangular tubes, so that the tool can have a certain amount of adjustment , but it depends on the passive adjustment of the spring and cannot be actively adjusted, and there is also the problem that if the deformation is greater than the passive amount of the spring, the cathode plate will be scratched.

Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in Figure 2, an embodiment of the present invention provides a stripping system for electrodeposited metal, which is used in the hydrometallurgical electrodeposition process to quickly and efficiently strip metal deposits from the cathode plate without damaging the cathode plate. include:

Frame, telescopic driving device, cathode plate supporting device, metal plate receiving bucket, stripping mechanism multi-directional limit device and stripping mechanism; among them,

The frame is a vertical frame structure;

The telescopic driving device is fixed on the upper part of the frame, and has a telescopic driving end that can be extended or retracted;

The cathode plate supporting device for supporting the cathode plate is arranged in the middle of the frame;

The metal plate receiving bucket is set at the lower part of the frame;

The stripping mechanism is connected to the telescopic driving end of the telescopic driving device, and the telescopic driving end faces the cathode plate support device, and can drive the stripping mechanism to move up and down along the cathode plate supported by the cathode plate support device;

The stripping mechanism multi-directional limiting device installed on the frame and capable of moving up and down along the frame is connected to the stripping mechanism, and the stripping mechanism's multi-directional limiting device performs multi-directional limiting on the up and down movement of the stripping mechanism;

The peeling mechanism includes: support frame, left rotating shaft, right rotating shaft, left knife holder, right knife holder, synchronous opening and closing mechanism of main stripping knife, left limit mechanism of main stripping knife, right limit mechanism of main stripping knife, two clips Angle adjustment device and main stripping knife;

Wherein, the supporting frame is connected with the telescopic driving end of the telescopic driving device, and the two sides of the supporting frame are connected with the multidirectional limit device of the peeling mechanism; The frames are all elongated structures. The left tool frame and the right tool frame are movable respectively on the left and right rotary shafts, and can rotate around the left and right rotary shafts at predetermined angles. The left tool frame and the right tool frame are relatively The central plane of the cathode plate set on the cathode plate support device is symmetrical; the main stripping knife synchronous opening and closing mechanism is arranged on the support frame, and the two ends of the driving part of the main stripping knife synchronous opening and closing mechanism are connected with the left knife rest and the right side respectively. The top of the knife rest is movably connected, and the synchronous part of the synchronous opening and closing mechanism of the main stripping knife is respectively movably connected with the top of the left knife rest and the right knife rest through two angle adjustment devices; the left limit mechanism of the main stripping knife and the main The right limit mechanism of the stripping knife is arranged on the support frame respectively, the top of the left knife rest is located in the space of the limit space of the left limit mechanism of the main stripping knife, and the top of the right knife rest is located at the space of the right limit mechanism of the main stripping knife. In the limited space; the bottom ends of the left knife rest and the right knife rest are respectively provided with main stripping knives, and the main stripping knives on the main stripping knife rests on both sides are in an inverted V shape with low sides and high middle.

As shown in Figure 2, in the above-mentioned stripping system, the telescopic driving device adopts a hydraulic drive cylinder (i.e. the main cylinder 5 in Figure 2), the hydraulic drive cylinder adopts a long-stroke cylinder, and the cylinder body of the hydraulic drive cylinder is fixed on the machine. The upper part of the frame, as the telescopic driving end, the hydraulic rod can be stretched up and down from the cylinder on the upper part of the frame. The hydraulic rod faces the cathode plate support device. The purpose of telescoping is to drive the stripping mechanism with the main stripping knife to move up and down. This driving device, which uses a single hydraulically driven cylinder to drive the peeling mechanism, has a simple, reliable, fast, and sufficient driving force. It cooperates with a full-stroke sensor that measures the position of the hydraulic rod of the cylinder, and can be positioned at any time when the main stripping knife moves up and down. All can be known, so that the subsequent precise control of the position of the main stripping knife can accurately strip metal deposits (such as zinc stripping) from the cathode plate.

As shown in Figures 2 and 3, in the above-mentioned stripping system, the driving part of the main stripping knife synchronous opening and closing mechanism of the stripping mechanism adopts an oil cylinder horizontally arranged between the left knife rest and the right knife rest (that is, in Fig. 2 The opening and closing oil cylinder 8) in the middle of this oil cylinder is fixedly located on the support frame, and the two ends are respectively connected with the upper ends of the left side knife rest and the right side knife rest movably. As shown in Figure 3, the synchronous parts of the peeling mechanism are the guide column on the support frame and the guide cylinder on the guide column. The guide cylinder can make the left and right knife rests open and close synchronously. The two included angle adjustment devices are movably connected with the upper ends of the left knife rest and the right knife rest respectively. Specifically, the two ends of the opening and closing oil cylinder 8 are respectively connected with the two side knife rests 161, 162 of the main stripping knife rest 16, and the guide cylinder 9 is respectively connected with the two side knife rests of the main stripping knife rest top 16 through two included angle adjustment devices 6. 161,162 are connected, and the guide cylinder 9 slides in the guide column 11. When the opening and closing oil cylinder 8 stretches, due to the existence of the guide cylinder 9, the top ends of the tool rests 161 and 162 on both sides can be moved synchronously. When the tops of both sides of the tool rests 161, 162 of the main stripping tool rest 16 move synchronously, because the two sides of the knife rests 161, 162 rotate around the respective rotating shafts 18, the distance between the upper ends of the two sides of the knife rests is controlled by the expansion and contraction of the opening and closing oil cylinder. Just can control the opening and closing of the knife rest bottom, thereby can guarantee that the blade opening and closing synchronization of the main stripping knife that the both sides knife rests 161,162 bottoms of the main stripping knife rest are set, avoid scratching the negative plate under the situation of asynchrony. The synchronous opening and closing mechanism of the main stripping knife can achieve the effect of synchronous opening and closing of the knife under the premise of only using one oil cylinder. Not only is the structure simple, the control is also simpler, and the synchronization effect of the main stripping knife is also better.

As shown in Figure 3, the main stripping knife left limit mechanism of the main stripping knife limit mechanism in the above-mentioned stripping mechanism and the main stripping knife right limit mechanism have the same structure, and are all formed by intervals. Positioning device and outer limiting device, between the inner limiting device and the outer limiting device is a limiting space.

As shown in Figure 3, in the above-mentioned peeling mechanism, the multi-directional limit device of the peeling mechanism includes: two guide rails, two groups of composite rollers and two back plates; The composite rollers are respectively arranged in two guide rails, and two groups of composite rollers are respectively fixedly connected to both sides of the supporting frame of the stripping mechanism through two backboards. Wherein, each group of composite rollers is composed of two rollers, and the two rollers are in rolling contact with the bottom surface and two side surfaces of the guide rail in the guide rail. The advantages of this simple and reliable limit device are: the rolling resistance is smaller than the sliding resistance, the main stripping knife is more smooth when peeling downward, and the life of the composite roller and guide rail is longer. In addition, since the composite roller rolls on three sides , when the main stripping knife strips zinc downward, it can bear the load in the left and right and front and rear directions, so that it can bear the force in the other two directions except the up and down direction, and the ability to bear the load is better than the single direction limit of the prior art way, and at the same time, the limit effect is good. Avoid the problem of peeling metal deposits or damaging the cathode plate due to loads in different directions affecting the main stripping knife.

As shown in Figure 4, the included angle adjustment device of the peeling mechanism is a connecting rod capable of adjusting the length formed by the left and right connectors and the two-way screw device connected between the left and right connectors; There are mutually opposite threads (for example, the left connecting piece is a left-handed thread, the right connecting piece is a right-handed thread, or the thread direction of the left and right connecting pieces is reversed, as long as it matches the thread of the two-way screw), the two-way screw device It is composed of a two-way screw and a lock nut at one end of the two-way screw. One end of the two-way screw is set in the thread of the left connecting piece to be threaded with the left connecting piece, and the other end is set at the right connecting piece. The screw thread is connected with the right connecting piece. Specifically, the structure of the included angle adjustment device 6 is shown in Figure 4. The two-way stud 33 is a two-way stud, one end is left-handed, and the other end is right-handed. By twisting the two-way stud to rotate in the threads of the two connectors, The distance between the left and right connectors 31, 34 on both sides can be adjusted, and then the distance between the top ends of the tool holders 161, 162 on both sides and the guide cylinder 9 can be fine-tuned. There are two included angle adjustment devices 6 on the same side of the tool rest, and each included angle adjustment device 6 can be adjusted separately, so that the angle between the blade of the main stripping knife and the cathode plate can be adjusted and controlled conveniently, so that when the stripping knife is closed, The knife edge and the cathode plate can be completely parallel to ensure that the four stripping knives can be well parallel to the cathode plate, avoiding damage to the cathode plate during peeling, and the structure is simple and easy to operate. After the adjustment is completed, the lock nut is tightened, and the function is to prevent the two-way screw rod and the connecting parts on both sides from rotating relative to each other after the adjustment is completed.

As shown in Figure 5, in the above-mentioned stripping system, the main stripping knives are composed of four stripping knives, two stripping knives are respectively set on the left side knife holder and the right side knife holder, and one of the two stripping knives on the main stripping knife holder on each side There is a gap between them. After being installed on the knife holder, it becomes an inverted V shape with low sides and high middle. This is in line with the actual shape of the pre-opened zinc plate. The openings on both sides are larger and the opening in the middle is smaller. The stripping knife with this structure conforms to the actual situation of the separation of the zinc plate and the cathode plate after the pre-opening, and is more conducive to the stripping of the zinc plate after the pre-opening. Moreover, the blade of the main stripping knife is steeper, and when the oil cylinder drives the main stripping knife to move up and down, it can provide greater cutting force, and the zinc sheet is easier to be stripped.

The knife holders on both sides are equipped with a shape matching the main stripping knife at the part where the stripping knife is installed, which can ensure that although there are two stripping knives, when the main stripping knife is closed, the two stripping knives can be in the shape of an inverted V. The cathode plates are kept parallel.

Fig. 6 is a schematic diagram of the hydraulic control system of the above-mentioned stripping system, which hydraulically controls the main cylinder 5 as the telescopic driving device and the opening and closing cylinder 8 as the synchronous opening and closing mechanism of the main stripping knife. The labels in the hydraulic control system schematically shown in Figure 6 indicate: A and B are balance valves, C is a pressure measuring point, D is a throttle valve, E is an electromagnetic pilot three-position four-way valve, F is a pressure reducing valve, and G is an accumulator. Energy device, H is the electric variable pump, I is the air filter.

As shown in Figure 7, in the above-mentioned stripping system, the cathode plate support device includes: two support plates, two cathode plate slots and two cathode plate stoppers; Above, a cathode plate slot is provided in the middle of each support plate, and a cathode plate limiting device is provided on the telescopic support plate outside each cathode plate slot. When the main stripping knife feeds downwards to strip zinc, because the stripping force is relatively large, it cannot be placed on the chain, and the cathode plate 14 is lifted and placed in the cathode plate slot of the support plate 13 of the cathode plate support device, and at the same time The cathode plate is limited in the left, right, front and back directions. Since the wider support plate has a large enough area, even if there is an error in the placement mechanism, the cathode plate may not be placed in the cathode plate slot, and the cathode plate can be guaranteed. It will not fall and hurt people, avoid safety accidents, and facilitate the subsequent processing of the cathode plate by workers.

Taking zinc stripping from the cathode plate as an example, the zinc stripping process using the stripping system of the present embodiment is as follows: when the deposited metal on the cathode plate reaches a certain thickness (hereinafter replaced by “zinc flakes”), the cathode is first removed from the electrolytic cell. The plate is hoisted to the conveying chain of the stripping system. After pre-stripping, a gap is made on the upper edge of the combination of the zinc sheet and the cathode plate. The part of the main stripping knife is stripped down to the bottom of the zinc sheet along the gap, and the zinc sheet is separated from the cathode plate. At this time, the cathode plate is still hung on the supporting device of the main stripping knife cathode plate. The receiving bucket enters the next process. Stripping other electrodeposited metals is similar to zinc stripping.
