Description

Technical Field

[0001] This utility model relates to the field of metal smelting technology, specifically to a cathode plate loading slot hanger. Background Technology

[0002] Hydrometallurgical zinc refining refers to the process of dissolving zinc from zinc calcined sand or other zinc sulfide materials and zinc sulfide concentrate in an aqueous solution to extract metallic zinc or zinc compounds. It consists of three main stages: zinc leaching, purification from the zinc acid solution, and zinc electrolytic deposition. In hydrometallurgical zinc refining, cathode and anode plates are typically suspended in an electrolytic cell, and direct current is applied to deposit metallic zinc on the cathode plate. After electrodeposition, the cathode plate is removed from the electrolytic cell, and the zinc adhering to it is stripped off in a zinc stripping area. The stripped cathode plate is then washed and reinstalled in the electrolytic cell for the next electrolysis cycle. The cathode and anode plates in the electrolytic cell are at different heights, with the upper surface of the cathode plate higher than that of the anode plate. Aluminum plates are typically used as cathode plates, and a crossbeam is installed on top of the cathode plate with lifting lugs fixed to it. The cathode plate is lifted using the combination of hooks and lifting lugs.

[0003] In the existing technology, when the cathode plate is lifted out of the electrolytic cell using a hanger, the hanger is prone to colliding with the anode plate. The hook on the hanger is also prone to colliding with the anode plate crossbeam, causing damage to the anode plate crossbeam. This may also cause some copper metal to leak into the electrolytic cell, affecting the stability of the copper content index of the zinc foil, restricting the improvement of electrolytic production indicators, and ultimately affecting the overall production efficiency and benefits. Summary of the Invention

[0004] This utility model addresses the problem that in existing technology, the hook of the cathode plate lifting bracket easily collidees with the anode plate crossbeam during the process of lifting the cathode plate out of the electrolytic cell. It provides a cathode plate out-of-cell lifting bracket that, while enabling the lifting of the cathode plate, also prevents the hook from directly contacting the anode plate crossbeam, effectively avoiding damage to the anode plate crossbeam, extending the service life of the anode plate, and preventing copper leakage into the electrolytic cell, ensuring the stability of the copper content index of the zinc foil, and improving product quality.

[0005] To achieve the above objectives, the technical solution of this utility model is: a cathode plate loading slot hanger, including a lifting frame, wherein multiple lifting components are longitudinally spaced on the lifting frame, and each lifting component includes two hooks symmetrically arranged on the lifting frame. Multiple cathode plates can be simultaneously loaded into loading slots using the multiple lifting components on the lifting frame.

[0006] The hoisting frame is symmetrically equipped with anti-collision buffer mechanisms, which include a fixing component, a blocking component, and a buffer component. The blocking component includes a mounting plate, a mounting block, and a rubber pad. The mounting block is fixedly mounted on the bottom of the mounting plate, and the rubber pad is located on the bottom of the mounting block. The mounting block and the rubber pad prevent the hook from directly contacting the anode plate beam, thus avoiding damage to the anode plate beam caused by the hook colliding with it.

[0007] The fixing component is connected to the hoisting frame, and the lower end of the fixing component extends to the bottom of the hoisting frame and is connected to the mounting plate. The mounting block is provided with buffer components on both sides. The buffer components are connected to the mounting plate and achieve the purpose of installing the blocking component on the hoisting frame through the fixing component. The buffer components play a buffering role during the descent of the hoisting frame to avoid excessive impact and damage to the cathode plate and anode plate during the descent of the hoisting frame.

[0008] Furthermore, the hoisting frame includes two longitudinal beams and a crossbeam spaced between the two longitudinal beams, with both ends of the crossbeam fixedly connected to the two longitudinal beams respectively; the hook is fixedly mounted on the longitudinal beams, and the hoisting frame is formed by the cooperation of the two longitudinal beams and the crossbeam.

[0009] Furthermore, symmetrical hanger rings are provided on the outer sides of both longitudinal beams, with the hanger rings on the two longitudinal beams corresponding to each other. The hanger rings facilitate the lifting of the hanger by the hoisting equipment, achieving the purpose of lifting the cathode plate out of the loading tank.

[0010] Furthermore, each end of the two longitudinal beams is vertically equipped with a hanger handrail, the upper part of which has an arc-shaped structure. The hanger handrails facilitate the operator's fine-tuning of the position of the hoisting frame, allowing the hook to be attached to the lifting lugs of the cathode plate beam.

[0011] Furthermore, the fixing assembly includes an adjusting screw, an upper locking nut, and a lower locking nut. A through hole is provided on the crossbeam for the adjusting screw to pass through. The lower end of the adjusting screw extends through the through hole to the bottom of the crossbeam and is fixedly connected to the mounting plate. The upper and lower locking nuts are disposed on the adjusting screw, with the upper locking nut located above the crossbeam and the lower locking nut located below the crossbeam. The upper and lower locking nuts secure the adjusting screw to the crossbeam, and the height of the blocking assembly and the buffer assembly can also be adjusted by the cooperation of the adjusting screw with the upper and lower locking nuts.

[0012] Furthermore, the buffer assembly includes a fixed sleeve, a guide slide rod, a buffer spring, and a second rubber pad. The fixed sleeve is fixedly installed at the bottom of the mounting plate. The upper end of the guide slide rod is slidably fitted inside the fixed sleeve, and the lower end is fixedly installed on a base plate. The second rubber pad is installed at the bottom of the base plate. The upper and lower ends of the buffer spring are connected to the mounting plate and the base plate, respectively. Through the action of the buffer spring and the second rubber pad, the descent of the hoisting frame is buffered, preventing damage to the cathode and anode plates.

[0013] Furthermore, the lower surface of the first rubber pad is at the same level as the lower end of the hook, and the height of the second rubber pad is lower than that of the first rubber pad. This is to ensure that the hook can be hooked onto the lifting lug on the cathode plate beam, and to ensure that the buffer assembly can cushion the descent of the lifting frame.

[0014] The beneficial effects of this utility model through the above technical solution are as follows:

[0015] This utility model has a reasonable structure and good performance. While enabling the lifting of the cathode plate out of the loading tank, it can also prevent the hook from directly contacting the anode plate beam, avoiding collisions between the hook and the anode plate beam. This effectively prevents damage to the anode plate beam, extends the service life of the anode plate, and also prevents copper metal from leaking into the electrolytic cell, ensuring the stability of the copper content index of the zinc sheet and improving product quality.

[0016] During the process of lifting the cathode plate out of the slot, the mounting block of the blocking component and the rubber pad prevent the hook from directly contacting the anode plate beam. The rubber pad contacts the cathode plate beam to prevent the lifting frame from driving the hook to continue to descend. The rubber pad serves as the base of the blocking component and acts as a limit to prevent the hook from directly colliding with the anode plate. At the same time, the purpose of installing the rubber pad at the bottom of the mounting block is to prevent damage to the cathode plate. The lower surface of the rubber pad is at the same level as the lower end of the hook to ensure that the hook can be hung on the lifting lug on the cathode plate beam without affecting the normal removal of the cathode plate from the slot.

[0017] This invention uses buffer components on both sides of the mounting block to cushion the descent of the hoisting frame, preventing excessive impact from direct contact between the blocking components and the cathode plate, which could damage the cathode plate. Specifically, the second rubber pad of the buffer component first contacts the cathode or anode plate, compresses the buffer spring, and the guide rod slides upward within the fixed sleeve, thus achieving a cushioning effect on the descent of the hoisting frame. The height of the second rubber pad is lower than that of the first rubber pad to ensure that the buffer component effectively cushions the descent of the hoisting frame. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] like Figures 1-4 As shown, a cathode plate loading / unloading rack includes a lifting frame with multiple lifting components longitudinally spaced on it. Each lifting component includes two hooks 5 symmetrically arranged on the lifting frame. In this embodiment, the number of lifting components on the lifting frame is 26, that is, the number of hooks 5 on the lifting frame is 52. The hooks 5 on the lifting frame achieve the effect of lifting and unloading cathode plates from the loading / unloading slot, allowing for simultaneous loading and unloading of 26 cathode plates.

[0025] The hoisting frame is symmetrically equipped with anti-collision buffer mechanisms, which include a fixing component, a blocking component, and a buffer component. The blocking component includes a mounting plate 9, a mounting block 10, and a rubber pad 11. The mounting block 10 is fixedly installed at the bottom of the mounting plate 9, and the rubber pad 11 is installed at the bottom of the mounting block 10. In this embodiment, there are two anti-collision buffer mechanisms on the hoisting frame. The mounting block 10 is welded and fixed to the bottom of the mounting plate 9, and the rubber pad 11 is made of corrosion-resistant rubber. When the cathode plate in the electrolytic cell is removed from the cell, the rubber pad 11 comes into contact with the cathode plate, preventing the hook 5 from continuing to descend, thereby preventing the hook 5 from directly contacting the anode plate beam and avoiding damage to the anode plate beam caused by the hook 5 colliding with it. The rubber pad 11, in contact with the cathode plate, not only protects the cathode plate but also provides a certain degree of buffering.

[0026] The fixing component is connected to the lifting frame, and its lower end extends below the lifting frame and is connected to the mounting plate 9. Buffer components are provided on both sides of the mounting block 10, and these buffer components are connected to the mounting plate 9. In this embodiment, each anti-collision buffer mechanism has two fixing components, each anti-collision buffer mechanism has four buffer components, and each mounting block 10 has two buffer components on each side. The buffer components on both sides of the mounting block 10 buffer the descent of the lifting frame, preventing excessive impact force from direct contact between the blocking components and the cathode plate, which could damage the cathode plate.

[0027] The hoisting frame includes two longitudinal beams 1 and crossbeams 2 spaced apart between the two longitudinal beams 1. Both ends of the crossbeams 2 are fixedly connected to the two longitudinal beams 1 respectively. The hooks 5 are fixedly mounted on the longitudinal beams 1. In this embodiment, there are five crossbeams 2 between the two longitudinal beams 1. Both ends of the crossbeams 2 are welded and fixed to the two longitudinal beams 1 respectively. Two anti-collision buffer mechanisms are respectively installed on the crossbeams 2 at both ends of the longitudinal beams 1. The upper end of the hooks 5 is welded and fixed to the longitudinal beams 1.

[0028] Both longitudinal beams 1 are symmetrically provided with hanger rings 3 on their outer sides, and the hanger rings 3 on the two longitudinal beams 1 correspond to each other. In this embodiment, there are two hanger rings 3 on the outer side of each longitudinal beam 1. The hanger rings 3 are welded and fixed to the longitudinal beam 1. The hanger rings 3 have an inverted "V" shape structure. The hanger rings 3 are used to facilitate the lifting of the hanger by lifting equipment, such as using an overhead crane.

[0029] Both ends of the two longitudinal beams 1 are vertically equipped with hanger handrails 4, the upper part of which has an arc-shaped structure. In this embodiment, the hanger handrails 4 are welded and fixed to the longitudinal beams 1. The purpose of the arc-shaped structure of the upper part of the hanger handrails 4 is to facilitate the worker to adjust the position of the hanger by holding the hanger handrails 4, so as to facilitate the hook 5 to be hung on the lifting lug on the cathode plate crossbeam.

[0030] The fixing assembly includes an adjusting screw 6, an upper locking nut 7, and a lower locking nut 8. A through hole is provided on the crossbeam 2 for the adjusting screw 6 to pass through. The lower end of the adjusting screw 6 extends through the through hole to the bottom of the crossbeam 2 and is fixedly connected to the mounting plate 9. The upper locking nut 7 and the lower locking nut 8 are disposed on the adjusting screw 6, with the upper locking nut 7 located above the crossbeam 2 and the lower locking nut 8 located below the crossbeam 2. In this embodiment, the upper locking nut 7 and the lower locking nut 8 can lock the adjusting screw 6 to the crossbeam 2. Furthermore, the length of the lower end of the adjusting screw 6 extending below the crossbeam 2 can be adjusted through the through hole on the crossbeam 2 and the action of the upper locking nut 7 and the lower locking nut 8, thereby adjusting the height of the blocking assembly and the buffer assembly.

[0031] The buffer assembly includes a fixed sleeve 12, a guide slide rod 13, a buffer spring 15, and a second rubber pad 16. The fixed sleeve 12 is fixedly installed at the bottom of the mounting plate 9. The upper end of the guide slide rod 13 is slidably sleeved inside the fixed sleeve 12, and the lower end is fixedly installed with a base plate 14. The second rubber pad 16 is installed at the bottom of the base plate 14. The upper and lower ends of the buffer spring 15 are respectively connected to the mounting plate 9 and the base plate 14. In this embodiment, the fixed sleeve 12 is welded and fixed to the bottom of the mounting plate 9. A limiting plate can be installed on the upper end of the guide slide rod 13. The diameter of the limiting plate is larger than the diameter of the opening at the lower end of the fixed sleeve 12 to limit the guide slide rod 13. The guide slide rod 13 is welded and fixed to the base plate 14. The two ends of the buffer spring 15 are welded and fixed to the mounting plate 9 and the base plate 14 respectively. The second rubber pad 16 is also made of corrosion-resistant rubber. The second rubber pad 16 contacts the cathode plate, which not only protects the cathode plate but also has a certain buffering effect. When the hoisting frame descends, the second rubber pad 16 first contacts the cathode plate or the anode plate. As the hoisting frame continues to descend, the buffer spring 15 is compressed, and the upper end of the guide slide rod 13 slides upward in the fixed sleeve 12 until the first rubber pad 11 contacts the cathode plate or the cathode plate is installed into the electrolytic cell.

[0032] The lower surface of the first rubber pad 11 is at the same level as the lower end of the hook 5, ensuring that the hook 5 can be hung on the lifting lug on the cathode plate beam without affecting the normal exit of the cathode plate from the slot. The height of the second rubber pad 16 is lower than the height of the first rubber pad 11, ensuring that the buffer assembly can buffer the descent of the lifting frame.

[0033] The working principle of this utility model is as follows: When the cathode plate is removed from the electrolytic cell, the hoisting frame is first hoisted to the top of the electrolytic cell by means of the hoisting equipment and the hoisting ring 3, and the hoisting frame moves downward. When the hook 5 approaches the lifting lug on the cathode plate beam, the rubber pad 16 first contacts the cathode plate. The hoisting frame continues to descend, the buffer spring 15 is compressed, and the upper end of the guide slide rod 13 slides upward in the fixed sleeve 12 until the rubber pad 11 contacts the cathode plate. Then, the operator can adjust the position of the hoisting frame by holding the hoisting frame handle 4 so that the hook 5 on the hoisting frame is hooked on the lifting lug on the cathode plate beam. Then, the hoisting frame can be lifted by the hoisting equipment, and the cathode plate is moved out of the electrolytic cell by the hook 5 and hoisted to the zinc stripping area.

[0034] After the zinc-stripped cathode plates are washed, they are then used for the loading operation. The cathode plates are hoisted to a position directly above the electrolytic cell using hoisting equipment. The hoisting frame is then lowered. During the descent, workers can adjust the position of the hoisting frame by holding the hoisting frame handle 4, adjusting the position of the cathode plates to be installed in the electrolytic cell. When the cathode plates are about to be installed in the electrolytic cell, the rubber pad 16 first contacts the anode plate. The hoisting frame continues to descend, the buffer spring 15 is compressed, and the upper end of the guide slide rod 13 slides upward within the fixed sleeve 12, providing a buffering effect, until the cathode plate beam is suspended on the electrolytic cell. Then, workers can again adjust the position of the hoisting frame by holding the hoisting frame handle 4, remove the hook 5 from the lifting lug on the cathode plate beam, and lift the hoisting frame using hoisting equipment to complete the loading operation of the cathode plates.

[0035] The embodiments described above are merely preferred embodiments of the utility model and are not intended to limit the scope of the utility model. Therefore, all equivalent changes or modifications made to the technical solutions described in the scope of the utility model patent application should be included within the scope of the utility model patent application.
