Description

Technical Field

[0001] The present invention relates to the technical field of cranes, and in particular to a manganese plate follow-up taking and placing system and method for an electrolysis workshop. Background Art

[0002] In the electrolytic manganese process, the electrolytic production workshop usually uses stainless steel sheets as cathode plates. The cathode plates are placed in the electrolytic cell, so that a layer of metallic manganese will adhere to the surface of the cathode plates. The metallic manganese on the surface of the cathode plates is then separated from the cathode plates through a stripping process. In the industry, the cathode plates to be used are generally called empty plates, and the cathode plates after electrolysis are called manganese plates.

[0003] Typically, 24 cathode plates are placed in a single electrolytic cell, arranged vertically in rows. After electrolysis is complete, the plates need to be removed individually, requiring significant labor and inefficiency. Furthermore, the electrolysis production workshop is subject to a high volume of acidic mist, creating a harsh working environment. Workers are required to wear gas masks, which can hinder breathing and be uncomfortable to wear for extended periods. This harsh working environment discourages workers from working in such conditions, hindering recruitment and significantly impacting the production of manganese metal.

[0004] The Chinese utility model patent with publication number CN215924204U discloses a crane for lifting electrode plates. By arranging a slot entry clamp and a slot exit clamp on the crane, mechanized grabbing and placement of cathode plates are achieved. However, the slot entry clamp and the slot exit clamp can only grab one row of corresponding cathode plates at a time, and there are idle clamps. In the process of transporting cathode plates, the crane only relies on the crane to travel back and forth between the electrolytic cell and the water glass tank and passivation liquid tank on one side. The transportation route and transportation time are relatively long, and work efficiency still needs to be further improved. Summary of the Invention

[0024] Step S1, adjusting the initial state: In the initial state, the row hook is parallel to the trolley end beam, the mobile gantry is located on one side of the transfer trough, there are at least two transfer troughs, namely the first transfer trough and the second transfer trough, and there are at least two placement slots, namely the water glass placement slot and the passivation liquid placement slot;

[0025] Step S2, empty board transfer: grab the empty board from the water glass placement slot of the mobile gantry through the lifting device, and transfer the empty board to the first transfer slot of the follower hanger;

[0026] Step S3, manganese plate transfer: grab the manganese plate from the electrolytic cell by using a sling and transfer the manganese plate to the second transfer tank of the follower hanger;

[0027] Step S4, transferring the empty plate from the first transfer tank to the electrolytic tank;

[0028] Step S5, transferring the manganese plate from the second transfer tank to the passivation solution placement tank of the mobile gantry;

[0029] Step S6, repeat the cycle of steps 1 to 5, and in this process, adjust the positions of the mobile gantry and the follower hanger in time so that the follower hanger is located above the side of the electrolytic cell containing the manganese plates to be transported, and at the same time, the empty plates to be transported or the positions in the cell to be used in the mobile gantry are correspondingly followed by the follower hanger.

[0030] Optionally, during the process of grabbing and placing empty plates or manganese plates, the X and Y positions of the spreader are changed by the lifting trolley and the lifting car, the Z position of the spreader is changed by the lifting mechanism, the different angular positions of the combing and grabbing mechanisms in the horizontal direction are changed by the adjustment mechanism, the spacing between the two groups of combing and grabbing mechanisms is changed by the upper adjustment component, and the horizontal position of a single group of combing and grabbing mechanisms is adjusted by the lower adjustment component.

[0031] Optionally, when grabbing an empty plate or a manganese plate, the row hooks of the combing and grabbing mechanism are first opened and then closed, so that the handle hook on the top of the cathode plate is hung in the row hooks, and after being lifted up for a distance, the combing teeth of the combing and grabbing mechanism are swung to a position where they are engaged with both sides of the empty plate or the manganese plate, and then the sling is moved in the X, Y and Z directions;

[0032] When putting down the empty plate or manganese plate, the spreader moves the empty plate or manganese plate to a position close to the corresponding trough, first open the combing teeth to release the empty plate or manganese plate from its clamping state, and then put the empty plate or manganese plate down into the corresponding trough. After the hooks are opened, they can be detached from the top handle of the empty plate or manganese plate, and then the spreader can be moved in the X, Y, and Z directions.

[0033] By adopting the above technical solution, the present invention has the following advantages:

[0034] The present invention cooperates with the spreader movement by arranging a follow-up hanger and a mobile gantry. The spreader can grab two rows of empty plates or manganese plates at a time, and the empty plates or manganese plates can be placed in the transfer trough first, effectively avoiding the spreader from making long distance round trips to get the empty plates or store the manganese plates. On the one hand, when the manganese plates are placed in the transfer trough, the spreader can immediately resume emptying, and directly grab the previously stored empty plates from the transfer trough and quickly place them in the electrolytic cell, effectively reducing the idle time of the electrolytic cell. The service life of the electrolytic cell can be effectively increased without having to wait for the spreader to be transported for a long time. On the other hand, the spatial movement of the mobile gantry, the follow-up hanger and the spreader can operate independently and cooperate with each other. Within the same time period, the three can act simultaneously to move with the transfer position so as to achieve the effect of completing the transfer in the shortest time, optimize the transfer route, and effectively save transfer time.

[0035] At the same time, a large amount of space can still be left between the bottom of the placement trough and the factory floor, which can be used to place other equipment or for workers to pass through, effectively utilizing the longitudinal space in the factory.

[0078] An embodiment of a method for taking and placing manganese plates in an electrolysis workshop:

[0079] A method for taking and placing manganese plates in an electrolysis workshop comprises the following steps:

[0080] Step S1, adjusting the initial state: In the initial state, the row hook 71 is parallel to the trolley end beam 12, the mobile gantry 9 is located on one side of the transfer slot 81, the transfer slot 81 has at least two, namely, the first transfer slot 81 and the second transfer slot 81, and the placement slot 92 has at least two, namely, the water glass placement slot 92 and the passivation liquid placement slot 92;

[0081] Step S2, empty board transfer: grab the empty board from the water glass placement slot 92 of the mobile gantry 9 by using a lifting device, and transfer the empty board to the first transfer slot 81 of the follower hanger 8;

[0082] Step S3, manganese plate transfer: grab the manganese plate from the electrolytic cell by using a sling and transfer the manganese plate to the second transfer tank 81 of the follower hanger 8;

[0083] Step S4, transferring the empty plate from the first transfer tank 81 to the electrolytic tank;

[0084] Step S5, transferring the manganese plate from the second transfer tank 81 to the passivation solution placement tank 92 of the mobile gantry 9;

[0085] Step S6, repeat the cycle of steps 1 to 5, and in this process, adjust the positions of the mobile gantry 9 and the follower hanger 8 in a timely manner so that the follower hanger 8 is located above the side of the electrolytic cell containing the manganese plates to be transported, preferably adjacent to the electrolytic cell and without hindering the spatial movement of the hanger and the manganese plates. At the same time, the empty plates to be transported or the positions in the tank to be used in the mobile gantry 9 are correspondingly followed by the follower hanger 8.

[0086] In the above steps, the empty plates or manganese plates are first placed at the transfer trough 81, which can avoid the spreader from traveling back and forth over long distances to fetch the empty plates or store the manganese plates.

[0087] Furthermore, during the process of grabbing and placing empty plates or manganese plates, the X- and Y-direction positions of the sling are changed by the lifting trolley and the lifting cart, the Z-direction position of the sling is changed by the lifting mechanism 22, the different angular positions of the combing and grabbing mechanism 7 in the horizontal direction are changed by the adjustment mechanism, the spacing between the two groups of combing and grabbing mechanisms 7 is changed by the upper adjustment component 5, and the horizontal position of a single group of combing and grabbing mechanisms 7 is adjusted by the lower adjustment component 6.

[0088] Furthermore, when grabbing an empty plate or a manganese plate, the row hooks 71 of the combing and grabbing mechanism 7 are first opened and then closed, so that the handle 10 on the top of the cathode plate is hooked in the row hooks 71, and after being lifted up for a distance, the combing teeth 72 of the combing and grabbing mechanism 7 are swung to a position where they are engaged with both sides of the empty plate or the manganese plate, and then the sling is moved in the X, Y, and Z directions;

[0089] When putting down the empty plate or manganese plate, the sling moves the empty plate or manganese plate to a position close to the corresponding trough body, first open the combing teeth 72 to release the clamping state of the empty plate or manganese plate, and then put the empty plate or manganese plate into the corresponding trough body. After the row hook 71 is opened, it can be detached from the top handle 10 of the empty plate or manganese plate, and then the sling can be moved in the X, Y and Z directions.

[0090] Taking step S2 as an example, the specific transfer process is as follows: the lifting trolley and the lifting car are operated to move the spreader to the top of the water glass placement groove 92 of the mobile gantry 9, the spreader is lowered by the lifting mechanism 22, the row hook 71 is opened and closed to hook the handle 10 on the top of the empty plate, and then the spreader is raised by the lifting mechanism 22;

[0091] Afterwards, the lifting trolley runs again, causing the sling to move horizontally to above the first transfer slot 81 in the follow-up hanger 8, and the sling is lowered through the lifting mechanism 22 to place the empty plates in the first transfer slot 81. During this process, the combing and grabbing mechanism 7 keeps the empty plates arranged neatly, and the adjustment mechanism fine-tunes the position between the two groups of combing and grabbing mechanisms 7 to adapt to cathode plates in different placement states.

[0092] Taking step S3 as an example, the specific transfer process is that the hoisting trolley is operated to move the sling horizontally above the electrolytic cell. In the working scenario of this embodiment, the extension direction of the electrolytic cell is parallel to the direction of the trolley main beam 11. The combing and grabbing mechanism 7 is rotated by the adjustment mechanism to make the row hook 71 parallel to the extension direction of the electrolytic cell. After the sling is lowered by the lifting mechanism 22, the gripping position is further fine-tuned by the adjustment mechanism until the row hook 71 is adjusted to be just above the manganese plate. The row hook 71 opens and closes to hook the handle 10 on the top of the manganese plate. At the same time, the combing teeth 72 of the combing and grabbing mechanism 7 engage the manganese plate, and then the sling is raised by the lifting mechanism 22.

[0093] Afterwards, the two sets of combing and grabbing mechanisms 7 are separated by adjusting the mechanism, and then the combing and grabbing mechanism 7 is rotated to make the two sets of hooks 71 parallel to the direction of the trolley end beam 12. The lifting trolley and the lifting mechanism 22 are operated to place the manganese plate into the second transfer slot 81 in the follower hanger 8.

[0094] The above embodiments do not impose any formal restrictions on the shape, material, structure, etc. of the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of protection of the technical solution of the present invention.
