Description

Technical Field

[0001] This utility model relates to the field of metal smelting, specifically to a ring-shaped zinc stripping unit. Background Technology

[0002] my country is a major producer and consumer of zinc in the world. The primary zinc production process is the hydrometallurgical process, where zinc sheets deposited at the cathode need to be peeled off the electrode plates. Manual peeling is labor-intensive, and the zinc electrowinning workshop suffers from acid fumes and harsh working conditions, hindering improvements in zinc smelting technology and production efficiency. Using a single machine for peeling requires multiple transfers of the electrode plates between different processes, wasting manpower and resources and impacting production efficiency. The existing fully automated peeling system (patent number CN202411098387.9) has many components, cumbersome electrode plate transfer, and requires a large floor space. Utility Model Content

[0003] To address the technical problems of high labor intensity, cumbersome plate transfer, and low production efficiency in the zinc stripping operation of existing wet zinc smelting processes, this utility model provides a ring-shaped zinc stripping unit.

[0004] A ring-shaped zinc stripping unit includes a ring conveyor chain, an infeed chain, an outfeed chain, and a stripping chain; the ring conveyor chain is equipped with electrode plate hooks; a transfer device is provided between the ring conveyor chain and the infeed chain, the outfeed chain, and the stripping chain; the ring conveyor chain is equipped with an opening device and a zinc stripping device; a stacking and transfer line is provided below the zinc stripping device.

[0005] In a preferred embodiment of the annular zinc stripping unit provided by this utility model, the infeed chain, the opening device, the zinc stripping device, the stripping chain, and the outlet chain are arranged sequentially along the conveying direction of the annular conveyor chain.

[0006] In a preferred embodiment of the annular zinc stripping unit provided by this utility model, the palletizing and transfer line includes a chute located below the zinc stripping device, a palletizing device is located below the chute, and a zinc stack conveyor chain is located below the palletizing device.

[0007] In a preferred embodiment of the annular zinc stripping unit provided by this utility model, a zinc stack transfer trolley is provided at the end of the stacking conveyor chain.

[0008] In a preferred embodiment of the annular zinc stripping machine provided by this utility model, a washing device is provided on the output chain.

[0009] Compared to existing technologies, the annular zinc stripping unit provided by this utility model adopts an annular conveyor chain, with other components cooperating with the annular conveyor chain. This results in a compact structure, saving layout space and allowing for flexible arrangement according to the factory layout. It also reduces equipment components and saves costs. The annular zinc stripping unit uses an annular conveyor chain to reduce the number of times the electrode plates are transferred, improving work efficiency. Electrode plates that are not completely stripped of zinc can be repeatedly stripped, further improving efficiency. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0013] Please also refer to Figure 1 and Figure 2 These are schematic diagrams of a ring-shaped zinc stripping machine and a palletizing and transfer line provided by this utility model.

[0014] The aforementioned annular zinc stripping unit includes an annular conveyor chain 1, with multiple electrode plate hooks 8 hanging below the annular conveyor chain 1, and the electrode plates 5 being hung on the electrode plate hooks 8.

[0015] The annular conveyor chain 1 is provided with an inlet chain 7, an opening device 6, a zinc stripping device 3, a scraper chain 2, and an outlet chain 9 in sequence along the conveying direction.

[0016] Each of the infeed chain 7, the reject chain 2, and the outfeed chain 9 is provided with a transfer device 11 between itself and the annular conveyor chain.

[0017] The transfer device 11 transfers the electrode plate 5 from the infeed chain to the annular conveyor chain 1, and then transfers the electrode plate from the annular conveyor chain 1 to the rejection chain 2 or the outfeed chain 9. The transfer device 11 is prior art, and its specific structure will not be described in detail here.

[0018] The opening device 6 is located below the annular conveyor chain 1. The electrode 5, on which the electrode hook 8 is hung, opens through the opening device 6 during transport. The opening device 6 is prior art, and its specific structure will not be described in detail here.

[0019] The zinc stripping device 3 is located below the annular conveyor chain 1. The electrode 5, which is hung by the electrode hook 8, undergoes zinc stripping operation via the zinc stripping device 3 during transport. The zinc stripping device 3 is existing technology, and its specific structure will not be described in detail here.

[0020] Below the zinc stripping device 3 is a palletizing and transfer line 4, which includes a chute 12 located below the zinc stripping device 3. Below the chute 12 is a palletizing device 15. The palletizing device 15 is prior art, and its specific structure will not be described in detail here. Below the palletizing device 15 is a zinc stack conveyor chain 13. At the end of the conveying direction of the zinc stack conveyor chain 13 is a zinc stack transfer trolley 14.

[0021] A washing device 10 is provided in the conveying direction of the plate output chain 9, and the washing device 10 cleans the electrode plates 5 conveyed on the plate output chain 9. The washing device 10 is prior art, and its specific structure will not be described in detail here.

[0022] In practice, multiple electrode plates 5 are placed at certain intervals onto the feed chain 7 using a multi-functional overhead crane. The feed chain 7 then transports the electrode plates 5 forward. The forward-transported electrode plates 5 are transferred from the feed chain 7 to the electrode plate hook 8 by the transfer device 11. The electrode plates 5 are then transported forward along the annular conveyor chain 1. First, the opening device 6 opens the zinc layer of the electrode plate 5, and then the zinc stripping device 3 strips the zinc.

[0023] The stripped zinc sheets fall into the stacking and transfer line 4 below, then through the chute 12 into the stacking device 15 for stacking. When the zinc sheets have accumulated to a certain amount, they are transported by the zinc stack conveyor chain 13 to the zinc stack transfer trolley 14, where they are transported away.

[0024] After zinc stripping, the electrode plate 5 continues to advance along the annular conveyor chain 1. If the zinc layer on the electrode plate 5 is not completely stripped, the transfer device 11 at the stripping chain 2 will transfer the electrode plate 5 to the stripping chain 2. Once a certain number are accumulated, they will be lifted away by a multi-functional overhead crane. The electrode plate 5 that is not completely stripped of zinc can also continue to advance along the annular conveyor chain 1 and pass through the zinc stripping device 3 again for zinc stripping operation.

[0025] If the zinc layer on the electrode plate 5 is completely peeled off, the transfer device 11 at the exit chain 9 will transfer the electrode plate 5 to the exit chain 9. As the electrode plate 5 is conveyed along the initial chain 9, the washing device 10 will clean the zinc-peeled electrode plate 5, and finally, it will be lifted away by a multi-functional overhead crane. The electrode plate hook 8 will return to the entry chain 7 to hang a new electrode plate 5.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
