Description

Technical Field

[0001] This utility model relates to the field of hydrometallurgical zinc refining technology, specifically to an auxiliary device for loading the zinc electrowinning process. Background Technology

[0002] The electrowinning process of wet zinc smelting mainly consists of stages such as loading tank, liquid management, crystal cleaning, vacuum tank removal, and automatic zinc stripping machine operation.

[0003] The loading and unloading process is typically completed by a self-made hoisting rake in conjunction with a bridge crane, with the assistance of multiple workers. This requires several workers to work together to perform clamping, hoisting, positioning, and securing. However, this manual method has significant drawbacks: First, it is inefficient. Due to the small electrode spacing, loading efficiency is directly related to the skill level of the assistants and the crane operator. A single loading operation can take more than 30 minutes if things don't go smoothly, and the bridge crane's hoisting can easily cause swaying and displacement, requiring repeated adjustments. Second, it presents significant safety hazards. During loading, personnel stand on both sides of the hoisting rake to assist in the loading process, which carries the risk of injury from electrode plates detaching due to jamming. Third, environmental factors increase the difficulty of loading. In the wet zinc electrowinning process, the electrode spacing is generally 60mm to 75mm, with the anode plate beam thickness being 20mm. Therefore, the loading width of each cathode plate is only 48mm, resulting in a very small spacing. Even a slight breeze can cause the plates to lose their position, making loading difficult and risky. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for the manual loading process in zinc electrowinning, which aims to facilitate operation, reduce labor intensity, and mitigate or reduce safety risks, thereby solving the problems existing in the prior art.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A zinc electrowinning process tank loading auxiliary device includes a bearing bracket 1, a rake 2, a rotating arm 3, and a positioning device 4. The rake 2 has bearing brackets 1 on both the front and rear ends and the left and right sides of its upper surface. The upper end of the rotating arm 3 is hinged to the bearing bracket 1, and the lower end of the rotating arm 3 is provided with the positioning device 4. Two rows of hooks 6 are provided on the left and right sides of the lower surface of the rake 2.

[0007] The rotating arm 3 has a two-section structure, consisting of an upper arm and a lower arm connected by a pin. The included angle between the upper arm and the lower arm is 0-145°. The upper end of the upper arm is hinged to the bearing bracket 1, and the lower end of the lower arm is connected to the positioning device 4.

[0008] The positioning device 4 has a number of positioning teeth 7 evenly arranged on its inner side, and the positioning device 4 has auxiliary arms 8 at both ends. The positioning device 4 also has connecting grooves 9 on its front and rear sides.

[0009] The positioning device 4 is made of carbon fiber material.

[0010] The distance between the tips of two adjacent positioning teeth 7 on the positioning device 4 is 60-100mm, and the distance between the bases of the teeth is 0-15mm.

[0011] The rake 2 has fixed frames 5 on its left and right sides.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] This invention achieves precise alignment and stable hoisting of the electrode plates during the loading process by adding a positioning device to the hoisting rake, significantly improving the loading efficiency and operational safety of the zinc electrowinning process.

[0014] The rotating arm of this invention, through the lever principle and its own weight, can effectively reduce the force required for manual operation, making it easier to evenly fix the cathode plate.

[0015] This invention offers several advantages: firstly, it significantly improves the efficiency of cathode plate installation; secondly, it reduces over-reliance on the skill level of crane operators and installation personnel; thirdly, it addresses the risk of personnel injury due to plate jamming or dropping; and fourthly, it reduces the difficulty of installation by further minimizing the electrode spacing.

[0024] Example 1

[0025] like Figure 1-4 This embodiment provides an auxiliary device for loading zinc electrowinning processes, including bearing supports 1, a lifting rake 2, a rotating arm 3, and a positioning device 4. Four bearing supports 1 are arranged on the front and rear ends and left and right sides of the upper surface of the lifting rake 2. The upper end of the rotating arm 3 is hinged to the bearing supports 1 via bearings, giving the rotating arm 3 the freedom to rotate around its axis. The positioning device 4 is arranged at the lower end of the rotating arm 3, and two rows of evenly distributed hooks 6 are arranged on the left and right sides of the lower surface of the lifting rake 2. The spacing of the hooks 6 is set to be equidistant according to the electrode plate size.

[0026] The rotating arm 3 has a two-section structure, consisting of an upper arm and a lower arm connected by a pin. The included angle between the upper arm and the lower arm is 0-145°, allowing for angle adjustment within the range of 0°-145°, with a maximum rotation angle limited to 145°, which is beneficial for precise positioning. The upper end of the upper arm is hinged to the bearing bracket 1, and the lower end of the lower arm is connected to the positioning device 4.

[0027] The positioning device 4 has a number of positioning teeth 7 evenly arranged longitudinally on its inner side. The positioning device 4 has auxiliary arms 8 at both ends and the positioning device 4 has connecting grooves 9 on its front and rear sides. The connecting grooves 9 and the rotating arms 3 form a mating installation interface.

[0028] The positioning device 4 is made of carbon fiber material, which has the characteristics of being lightweight and high-strength.

[0029] The distance between the tips of two adjacent positioning teeth 7 on the positioning device 4 is 60-100mm, and the distance between the bases of the teeth is 0-15mm.

[0030] The rake 2 has symmetrically arranged fixing frames 5 on its left and right sides. The fixing frames 5 are symmetrically installed on both sides of the rake 2 and are vertically aligned with the bearing bracket 1 to form a stable support structure.

[0031] In this embodiment, tools are manufactured based on the on-site equipment, facilities, and technological conditions. The interpole spacing is 68mm, the anode plate beam thickness is 20mm, and the cathode plate, including the cathode insulating strip, is 15mm thick. Each slot contains 49 anode plates and 48 cathode plates. Calculations show that the insertion space for each cathode plate is 48mm. Therefore, the width of the guide area, the core component of this slotting auxiliary device, should be set to the insertion space distance, while the width of the fixing area is less than the insertion space distance but greater than the widest distance of the cathode plate surface.
