Description

Zinc stripping, scrubbing and plate removing and supplementing integrated equipment and system

Technical Field

The invention relates to the technical field of hydrometallurgy electrodeposition equipment, in particular to zinc stripping, scrubbing and plate removing and supplementing integrated equipment and a system.

Background

The wet zinc smelting process includes setting cathode plates and anode plates in the solution of electrolytic bath, alternately arranging the cathode plates and the anode plates in certain interval, adsorbing metal ions onto the cathode plates in the electrolytic bath, taking partial cathode plates out of the electrolytic bath with the special crane for the cathode plates when the metal adsorbing layer reaches certain thickness, stripping the deposited metal zinc sheet from the cathode plates, smelting and casting to form zinc ingot to obtain the final product.

The plate area of the domestic common cathode plate is generally between 1.13 square meters and 3.2 square meters. The metal zinc sheet stripped and deposited from the negative plate is heavy physical labor, particularly a large polar plate with the square meter of 3.2, the weight of the zinc sheet attached to the negative plate reaches about 80kg and exceeds the normal manual operation range, the manual stripping mode becomes more and more difficult, huge manpower is consumed, the personal safety hidden danger also exists, in addition, the acid mist in a zinc electrolysis workshop is heavy, the health of workers is seriously harmed, and the cost of labor is also rapidly increased. In order to save labor force, improve productivity and improve labor conditions, all large zinc smelting enterprises and equipment manufacturing enterprises in the world actively develop and apply mechanization and automation zinc stripping, solve the mechanization and automation problems of main procedures of zinc stripping operation, including a zinc sheet stripping process and a cathode plate scrubbing process, and preliminarily realize mechanization and automation of zinc stripping operation.

At present, a 3.2 square meter large polar plate zinc stripping unit introduced from abroad or produced in China mostly adopts a central arrangement mode of an electrolysis workshop, namely zinc plate stripping equipment and negative plate scrubbing equipment are arranged in the middle of a main span of the electrolysis workshop. The zinc sheet stripping equipment and the brushing equipment for the stripped cathode plate are both provided with cathode plate transmission chain equipment, the transmission chain equipment is used for receiving a whole suspended cathode plate (generally 57 cathode plates) suspended and transported by a travelling crane, the cathode plate is supplied for the zinc stripping equipment and the brushing equipment through the cathode plate transmission chain equipment, the cathode plate after zinc stripping is transmitted to a travelling crane lifting storage station through the cathode plate transmission chain equipment, then the cathode plate is lifted to the cathode plate transmission chain of the brushing equipment through the travelling crane, the cathode plate is transmitted to the brushing equipment through the cathode plate transmission chain to be brushed, the brushed cathode plate is returned to an electrolytic bath through the travelling crane, and a zinc stripping brushing operation cycle is completed. The zinc stripping unit arrangement scheme has the advantages of compact layout of zinc stripping equipment, small occupied area and capital construction cost saving; however, the cathode plate after zinc stripping needs to be lifted to a cathode plate transmission chain where the brushing equipment is located by a travelling crane, and the travelling crane does one lifting action more than once. Taking 15 ten thousand tons of zinc output as an example, an electrolysis workshop generally has 110 electrolytic tanks, the number of the cathode plates for crane lifting is very large, the requirement of mechanical zinc stripping speed cannot be met, a zinc stripping unit is usually required to be stopped to wait for the cathode plates, the zinc stripping speed and efficiency are influenced, the zinc output and the zinc unit consumption are further influenced, and the adverse effect is brought to the zinc production. A plurality of domestic large polar plate zinc electrolysis production plants hope to reform the existing large polar plate zinc stripping machine set, improve the zinc stripping efficiency of the existing equipment and improve the automation operation level.

Because the domestic zinc electrolysis raw materials have wide sources and complex components, and the contents of chlorine and fluorine ions are higher, the domestic zinc hydrometallurgy process conditions are poorer, and the electrolyte index fluctuation is larger, the adhesion of the electrolytic zinc sheet and the cathode plate is serious, and the operation object has great uncertainty. The existing stripping equipment can not well adapt to the situation, the zinc sheet cannot be stripped, cannot be stripped and cannot be completely stripped, the damage condition of a cathode plate is serious, the workload of picking out a defective plate and supplementing a new plate in production is large, the auxiliary treatment operation needs to be carried out manually after the machine is shut down, the plate is manually picked and supplemented, the operating efficiency of an automatic zinc stripping unit is greatly reduced, and the electrolytic production is greatly influenced. In addition, great energy and physical strength are required to be consumed in manual plate removing and plate supplementing operations, so that the labor cost is high, and the safety management risk is more existed.

In summary, most of the currently introduced and domestic mechanized large-polar-plate zinc stripping equipment can cause automatic zinc stripping interruption in the processes of defective plate stripping and qualified plate supplementing, which affects the operating efficiency of a zinc stripping unit and requires more manpower and material resources; the cathode plate after zinc stripping needs to be lifted to a cathode plate transmission chain where the scrubbing equipment is located by a travelling crane, the travelling crane lifting process is added once, the working load of the travelling crane is increased, the waiting time of a zinc stripping unit is prolonged, and the zinc stripping production efficiency is influenced. Therefore, on the basis of the arrangement mode of the existing introduced and domestic mechanical zinc stripping equipment, a zinc stripping unit with the functions of automatically transferring the negative plate and removing and supplementing the plate is researched, the existing zinc stripping production line is improved, and the automatic transfer of the negative plate from the zinc stripping line to the plate brushing line and the automatic plate removing and supplementing are very necessary. On the one hand, the mechanization and automation degree of the zinc stripping unit can be further improved, the operation efficiency of the zinc stripping unit is obviously improved, on the other hand, the labor intensity of personnel in the zinc stripping production process can be reduced, the number of auxiliary zinc stripping personnel is reduced, the operation efficiency of the personnel is improved, the production efficiency and the economic benefit of enterprises are improved, and the production safety is improved.

The first prior art is as follows:

the invention patent publication No. CN101368283B discloses a cathode plate stripping system comprising a stripping device, an upstream storage area, a downstream storage area and a transport system. The un-stripped cathode plate is firstly taken out from the electrolytic bath by the whole crane of the cathode plate and is transported to the upstream storage area of the stripping system, the cathode plate is transported to the stripping device by the transport system, the cathode plate stripped at the stripping device is transported to the downstream storage area by the transport system, when the stripped cathode plate is discharged to the downstream storage area, the cathode plate is lifted to the plate brushing line by the whole crane of the cathode plate, and the cathode plate after the plate brushing is returned to the electrolytic bath by the whole crane of the cathode plate. The technical scheme has the advantages that the whole zinc stripping unit is simple and reliable in structure and low in failure rate, zinc stripping equipment can simultaneously strip zinc from the cathode plates of the left electrolytic cell and the right electrolytic cell in the main bay of a factory building, and the equipment utilization rate is high.

The cathode plate stripping system of the prior art has at least the following problems: the cathode stripping system has no mechanical automatic plate picking function of bad plates and no mechanical automatic plate supplementing function of qualified plates, cannot realize mechanical plate picking and supplementing, and influences the operation efficiency of a zinc stripping unit. In addition, in the negative plate stripping system, the stripped negative plate coming out after the stripping of the zinc stripping equipment needs a negative plate travelling crane to hoist the whole hung negative plate to the plate brushing equipment, and the operation efficiency of the zinc stripping unit can be influenced by the transferring process.

The second prior art is:

In addition, in the negative plate stripping system, the stripped negative plate which comes out after being stripped from the zinc stripping device is directly conveyed to the plate brushing line from the zinc stripping line by the negative plate transverse moving device, a negative plate transition stop station is not arranged in the middle, and as the distance between the zinc stripping line and the plate brushing line is large (about 3-4 m), much time is wasted when the negative plate is conveyed from the zinc stripping line to the plate brushing line, and the operation efficiency of the whole zinc stripping system is influenced.

The prior art is three:

CA104499005A discloses a plate picking, plate supplementing, transferring device and method for a post-zinc-stripping robot and a negative plate stripping system for a zinc stripping production line. The industrial robot grabs the stripped cathode plate from the input chain conveying device, if the cathode plate is well stripped, the cathode plate is placed into the output chain conveying device, and the cathode plate is brushed and then returned to the electrolytic bath by the cathode plate travelling crane; if the plate is a bad plate, the industrial robot is placed into the plate picking frame, then the qualified negative plate is picked from the plate supplementing frame and placed into the output chain conveying device, the vacancy of the negative plate in the zinc stripping system caused by plate picking is filled, and the production continuity is guaranteed.

The third prior art cathode plate stripping system has at least the following problems: the size of the plate picking frame and the plate supplementing frame in the cathode stripping system is small, the number of the cathode plates capable of being stored is small, bad plates and supplementary qualified plates need to be frequently lifted, the positions of the plate picking frame and the plate supplementing frame are not in the working range of the cathode plate travelling crane, and the cathode plates need to be lifted by being provided with other travelling cranes. In addition, one industrial robot needs to complete both plate removing work and plate supplementing work, the operation steps are performed in series, and the time consumption of the operation process is high, so that the operation period of a zinc stripping unit can be prolonged in the plate removing and plate supplementing processes, and the operation efficiency and the production capacity of the zinc stripping unit are reduced.

The prior art is four:

the invention patent of publication No. CN106086943B discloses a zinc sheet stripping system with functions of plate removing, supplementing and cathode plate transferring, which is also based on the central arrangement mode of the electrolysis workshop of the existing large-plate zinc stripping unit and is added with the functions of plate removing, supplementing and cathode plate transferring. The system comprises: the device comprises a pre-stripping device, a main stripping device, a board brushing device, a board picking device, a board supplementing device, a negative plate conveying device, a negative plate interval adjusting device, a negative plate transverse moving device and the like. After receiving 57 cathode plates, the cathode plate transmission equipment starts to transmit the cathode plates to the zinc stripping equipment in a stepping (180mm) mode, the zinc sheets on the cathode plates are pre-opened by the pre-stripping equipment, when the zinc sheets which are pre-opened are transmitted to the position near the main stripping equipment, the cathode plate spacing adjusting equipment adjusts the cathode plates from one-time plate spacing (180mm) to three-time plate spacing (540mm), meanwhile, the loading of the cathode plates to the main stripping equipment is completed, the main stripping equipment completely strips the zinc sheets of the pre-opened cathode plates, the cathode plate spacing adjusting equipment unloads the cathode plates which are successfully stripped from the main stripping and puts the cathode plates back to a transmission chain, recovers one-time plate spacing (180mm), meanwhile, the main stripping equipment is loaded with new cathode plates, the plate stripping trolley, the plate supplementing trolley and the cathode plate transverse moving equipment transmit the stripped cathode plates to the single plate brushing machine, and the brushed cathode plates are output and stored by the cathode plate transmission equipment in a whole, and finally, the whole hung cathode plate is returned to the electrolytic cell in the A line by the cathode plate travelling crane, and the zinc stripping work of the electrolytic cell in the A line can be completed by repeating the steps.

If the plate removing trolley, the plate supplementing trolley and the cathode plate transverse moving equipment are in failure, the whole set of zinc peeling system can be recovered to the original state of lifting the cathode plate by a travelling crane through the lifting adjustment of a plurality of cathode plates, and adverse effects are caused to production. In addition, in the technical scheme, the plate removing and supplementing operation is carried out on the main span of the electrolytic plant, and production personnel can often carry out the plate removing and supplementing operation on the main span of the electrolytic plant, so that the danger of collision with the automatic traveling crane of the negative plate exists.

The operation process of the zinc stripping brush plate stripping plate repairing integrated system comprises the following steps:

the cathode plate operation process of the first zinc stripping unit 301 and the second zinc stripping unit 302 in the zinc stripping process is shown in fig. 7.

For the first zinc stripping unit 301, after the cathode plate crane 2 above the electrolytic bath 101 in the row a puts a whole suspended 57 cathode plates on the zinc stripping line transmission chain 43 of the main bay of the factory building, the zinc stripping line transmission chain 43 starts to transmit the cathode plates in a stepping manner (180mm each time) towards the pre-stripping device 41. The pre-stripping device 41 firstly pre-opens the zinc sheets on the cathode plate, when the pre-opened zinc sheets are conveyed to the lower part of the main stripping device 42, the distance between the cathode plates is adjusted from one time (180mm) of plate arrangement to three times (540mm) of plate arrangement, meanwhile, the loading of the cathode plate on the main stripping device 42 is completed, and the main stripping device 42 completely strips the pre-opened zinc sheets on the cathode plate. The cathode plate, having completed the zinc sheet stripping, is unloaded from the main stripping means 42 and placed back to the zinc stripping line conveyor chain 43, restoring one time (180mm) the row plate spacing of the cathode plate. The zinc wire stripping and plate reversing mechanism 71 transfers the negative plate on the zinc wire stripping transmission chain 43 of the main span of the factory building to the zinc wire stripping lengthening chain 44, and the image recognition device recognizes the surface condition of the negative plate and marks the bad plate in the process. For the cathode plate with good state, the plate hanging mechanism 73 forks the cathode plate from the zinc wire stripping lengthening chain 44 to the transverse plate moving mechanism 75; for a bad cathode plate, the plate hanging mechanism 73 rejects the cathode plate and places the rejected cathode plate on the plate rejecting chain 74. The plate taking mechanism 76 takes the cathode plate off the transverse plate moving mechanism 75, puts the cathode plate on the brushing line extension chain 53, then transfers the cathode plate to the brushing line transmission chain 52 in the main span of the factory building through the brushing line plate reversing mechanism 78, and then enters the brushing device 51 for brushing, and the brushed cathode plate is lifted by the cathode plate travelling crane 2 and transported back to the electrolytic bath 101 in the A row to finish the whole process of the zinc stripping and brushing operation of the cathode plate. For the second zinc stripping unit 302, the cathode plate zinc stripping and brushing operations are the same as those of the first zinc stripping unit 301, and the description is not repeated.

The operation flow of the cathode plate in the zinc stripping process of the third zinc stripping unit 303 is shown in fig. 8.

The third zinc stripping unit 303 is responsible for the zinc stripping and brushing work of the cathode plate in the electrolytic bath 101 in the row A or the electrolytic bath 102 in the row B. For the third zinc stripping unit 303, the operation flow of the cathode plate of the electrolytic bath 101 in the stripping A row is the same as the operation process of the first zinc stripping unit 301; the operation flow of the cathode plate of the B-row electrolytic bath 102 is the same as the operation process of the second zinc stripping unit 302. The third zinc stripping unit 303 can flexibly schedule according to the zinc stripping progress condition of the cathode plate of the A-row or B-row electrolytic cell, ensures the relative balance of zinc stripping operation of the A-row electrolytic cell 101 and the B-row electrolytic cell 102, and improves the zinc stripping efficiency and the zinc electrolysis efficiency of a zinc electrolysis workshop.

The working process and principle of the wire stripping and plate falling mechanism 71 and the wire brushing and plate falling mechanism will be further explained by taking the wire stripping and plate falling mechanism 71 as an example.

(1) Initial position

The wire stripping and plate falling mechanism 71 continuously and circularly reciprocates in the working process, and for convenience of description, a starting point is set as an initial position of the wire stripping and plate falling mechanism 71, and the initial position is shown in fig. 9. At this time, the first chassis 7121 of the first carrying trolley 712 of the zinc wire stripping and plate reversing mechanism 71 is at the left end position, the first lifting guide rod assembly 7122 is at the falling bottom position, the cathode plate for stripping zinc sheets is already placed on the left side fork opening and the right side fork opening of the plate placing frame 72, the zinc wire stripping transmission chain 43 conveys the cathode plate to the right side by one step, and the cathode plate for stripping zinc sheets is already arranged on the chain right above the left side fork opening of the three-fork plate 7123; the extended chain 44 of stripped zinc wires conveys one cathode plate to the right, leaving a free position at the tooth slot of the chain directly above the sprocket shaft, where it can receive the cathode plate. The movement of the zinc wire stripping and plate reversing mechanism 71 can be divided into four steps of lifting the cathode plate, horizontally moving the cathode plate, placing the cathode plate and returning to the initial position.

(2) Lifting cathode plate

As shown in fig. 10, the lower cavity of the first lift cylinder 714 is filled with pressurized oil to drive the first lift guide rod assembly 7122 to ascend, after the three-forked plate 7123 ascends, the left fork firstly lifts the rightmost cathode plate on the zinc wire stripping transmission chain 43, then the middle fork and the right fork of the three-forked plate 7123 respectively lift the two cathodes on the plate placing frame 72, and the zinc wire stripping plate reversing mechanism 71 is in the lifting position in fig. 9. At this time, the cathode plate is separated from the limitation of the stripping zinc wire transmission chain 43 and the plate placing frame 72, and can move in the horizontal direction.

(3) Horizontal moving negative plate

As shown in fig. 11, the left chamber of the first horizontal oil cylinder 713 is filled with pressure oil to drive the first chassis 7122 to move rightward until reaching the right end position of horizontal movement, at this time, the cathode plate of the left fork of the three-forked plate 7123 moves right above the left fork of the plate placing frame 72, the cathode plate of the middle fork of the three-forked plate 7123 moves right above the right fork of the plate placing frame 72, and the cathode plate of the right fork of the three-forked plate 7123 moves right above the vacated position of the zinc stripping line extension chain 44, so that the horizontal movement of the three cathode plates is completed.

After the cathode plate is horizontally moved by the wire stripping and plate reversing mechanism 71, the wire stripping transmission chain 43 conveys the cathode plate one step (180mm) to the right, and the wire stripping and plate reversing mechanism 71 is ready for next plate reversing.

(4) Down-placed negative plate

As shown in fig. 12, pressurized oil is fed to the upper cavity of the first lift cylinder 714 to drive the first lift guide rod assembly 7122 to descend to the bottom position, in the process, the three-fork plate 7123 places the cathode plate carried by the left fork opening on the left fork opening of the plate placing frame 72, the three-fork plate 7123 places the cathode plate carried by the middle fork opening on the right fork opening of the plate placing frame 72, the three-fork plate 7123 places the cathode plate carried by the right fork opening on the zinc stripping line extension chain 44, and at the moment, all three cathode plates move to the right by 540 mm.

After the cathode plate is put down by the wire stripping and plate falling mechanism 71, the wire stripping lengthening chain 44 forwards transmits the cathode plate by one step (180mm), and the position of the cathode plate is vacated to prepare for next plate putting.

(5) Return to the initial position

As shown in fig. 9, the first horizontal cylinder 713 is communicated with the right chamber of the pressure oil to drive the first base plate 7122 to move leftwards until reaching the left end position of horizontal movement. At the moment, the zinc wire stripping transmission chain 43 also moves rightwards by one time (180mm) of the plate arrangement distance, the cathode plate is moved to the position right above the left fork opening of the three-fork plate 7123, preparation is made for moving the plate by the zinc wire stripping and plate reversing mechanism 71 next time, meanwhile, the cathode plate which is just placed just before is also moved rightwards by one time (180mm) of the plate arrangement distance, and the position occupied before the plate is vacated is made for placing the cathode plate next time. The zinc wire stripping and plate falling mechanism 71 returns to the left initial position shown in fig. 9, and the zinc wire stripping and plate falling mechanism 71 realizes the long-distance transfer of the cathode plate from the factory main span zinc wire stripping transmission chain 43 to the factory off-span zinc wire stripping lengthening chain 44 through the moving process, so that the flexible connection of the factory off-span equipment and the factory main span equipment is realized.

The hanging plate mechanism 73 is similar to the operation principle of the zinc wire stripping and plate reversing device 71, and the difference is that the hanging plate mechanism 73 has two horizontal moving distances (divided into two conditions of a middle stroke and a long stroke) and two lifting heights (divided into two conditions of a high position and a middle position), and the hanging plate mechanism 73 is respectively used for hanging a cathode plate in a good state on a hook 755 of the transverse plate moving mechanism 75 or rejecting a bad plate and placing the bad plate on a chain of a plate rejecting chain 74.
