Technical Field
[0001] The utility model relates to the technical field of waste residue recycling, and more specifically, to a device for recycling waste residue in zinc hydrometallurgy. Background Art
[0002] Zinc hydrometallurgy is an important metal smelting process, which is widely used in the production of zinc. However, the waste residue generated in the process of zinc hydrometallurgy has always been a thorny problem. Traditional treatment methods often simply landfill or stack it, which not only occupies a large amount of land resources, but also may cause the leakage of harmful substances, causing serious pollution to the environment. To solve this problem, researchers have begun to explore various waste residue treatment technologies. Among them, physical methods such as screening and crushing can reduce the volume of waste residue to a certain extent, but cannot effectively change the composition and properties of the waste residue; chemical methods such as acid leaching and redox can recover valuable metals in the waste residue, but are often accompanied by the use of a large amount of chemical reagents and wastewater discharge, causing secondary pollution to the environment.
[0003] Under this background, the waste residue recycling device for zinc hydrometallurgy came into being. It aims to achieve the efficient recycling of waste residue in zinc hydrometallurgy through physical and mechanical means, while minimizing the impact on the environment. The research and development of the waste residue recycling device for zinc hydrometallurgy not only helps to solve the problem of waste residue treatment in zinc hydrometallurgy, but also promotes the recycling of resources, achieving a win-win situation of economic and environmental benefits.

[0031] As Figures 1-6 shown, this embodiment provides a device for recycling waste residue in hydrometallurgical zinc smelting, including a recycling bin 1. Upper and lower through plates 11 and 12 are respectively fixed at the upper and lower ends of the recycling bin 1. A conical support 2 is movably connected to the inner ends of the upper through plate 11 and the lower through plate 12. A conical groove 3 is provided at the outer end of the conical support 2. An annular groove 4 is provided at the inner end of the conical groove 3. Inner and outer arc-shaped rods 5 and 6 are provided at the inner end of the annular groove 4. An arc-shaped groove 7 is provided at the inner end of the outer arc-shaped rod 6. A positioning rod 8 is provided at the inner end of the arc-shaped groove 7. A reciprocating lead screw 9 is provided at the outer end of the outer arc-shaped rod 6. A telescopic spring 10 is provided between the outer arc-shaped rod 6 and the inner arc-shaped rod 5. A lower screening plate 13 is provided at the lower end of the conical support 2. A linkage spring 14 is provided between the lower screening plate 13 and the lower through plate 12. A linkage motor 15 is provided at the center of the lower screening plate 13.
[0032] The recycling bin 1 serves as a storage container for raw materials, and its stable structure ensures the smooth inflow of waste residue.
[0033] The upper through plate 11 and the lower through plate 12 form a closed circulation system, facilitating the flow and control of waste residue.
[0034] The conical groove 3 provides a channel for the flow of waste residue and allows for preliminary screening of the waste therein.
[0035] The inner arc-shaped rod 5 and the outer arc-shaped rod 6: Through staggered arrangement, effective grinding of waste residue is achieved, and it has an adjustable structure that can adapt to the processing requirements of waste residue with different particle sizes.
[0036] The arc-shaped groove 7 and the positioning rod 8 provide guidance and support for the grinding of waste residue, ensuring the stability of the grinding process.
[0037] The reciprocating lead screw 9 and the telescopic spring 10 provide a power source, enabling the inner arc-shaped rod 5 and the outer arc-shaped rod 6 to generate reciprocating motion and enhancing the grinding effect.
[0038] The waste residue of zinc hydrometallurgy is poured from above the recycling bin 1 to start its recycling process; the waste residue first enters the conical trough 3. Driven by the reciprocating lead screw 9, the inner arc rod 5 and the outer arc rod 6 generate reciprocating motions to preliminarily grind the waste residue; as the waste residue flows, it will encounter the conical support 2, where the grinding particles further refine the waste residue; after preliminary grinding, the waste residue flows into the annular groove 4, where the inner arc rod 5 and the outer arc rod 6 are arranged in a staggered manner according to a specific arrangement to form multiple grinding areas for deep grinding of the waste residue; during the grinding process, the particle size of the waste residue continuously decreases. At the same time, due to the relative motion between the inner arc rod 5 and the outer arc rod 6, the waste residue is evenly dispersed throughout the grinding area; when the waste residue reaches a certain fineness, it will pass through the lower screening plate 13 in the chute, which is an important separation link; the lower screening plate 13 is driven by the linkage spring 14 to move up and down in the chute to screen the waste residue and separate the fine-grained materials that meet the requirements; the screened fine-grained materials flow out through the chute to complete the entire recycling process of the waste residue of zinc hydrometallurgy.
[0039] The outer ends of the conical support 2 are evenly distributed with grinding balls, the inner end of the conical trough 3 is provided with grinding particles, the annular groove 4 is embedded and installed at the inner end of the conical trough 3, and the annular grooves 4 are arranged at equal intervals in the conical trough 3.
[0040] The grinding particles are installed in the conical support 2 and the conical trough 3, which increases the grinding efficiency of the waste residue.
[0041] The inner end of the annular groove 4 is movably connected to the inner arc rod 5 and the outer arc rod 6. The numbers of the inner arc rod 5 and the outer arc rod 6 are both set to two groups. The inner arc rod 5 and the outer arc rod 6 are arranged in a staggered manner, and the two groups of inner arc rods 5 and the two groups of outer arc rods 6 are arranged in a circular array along the annular groove 4.
[0042] Both ends of the inner arc rod 5 are fixedly connected to the positioning rod 8. The positioning rod 8 slides along the arc groove 7. The arc groove 7 is embedded and installed at the inner end of the outer arc rod 6, and the inner arc rod 5 slides along the inner side of the outer arc rod 6.
[0043] The telescopic spring 10 connects the outer arc rod 6 and the inner arc rod 5. The lower end of the conical support 2 is fixedly connected to the lower screening plate 13.
[0044] The outer end of the lower screening plate 13 is provided with a chute, and the chute is connected through the conical trough 3.
[0045] The lower screening plate 13 slides up and down along the chute, and the conical support 2 is movably connected to the linkage motor 15.
[0046] The linkage motor 15 and the reciprocating lead screw 9 provide power to drive the conical support 2 to rotate, realizing the efficient grinding of the waste residue.
[0047] The lower end of the conical support 2 is movably connected to the lower through plate 12 through a linkage spring 14.
[0048] The lower screening plate 13 and the linkage spring 14 screen the waste residue through a sliding mechanism to separate fine-grained materials that meet the requirements.
[0049] The chute and the linkage motor 15 ensure the smooth movement of the lower screening plate 13 and improve the screening efficiency.
[0050] When this application is in use: When in use, start the linkage motor 15 and the reciprocating lead screw 9, pour the waste residue from zinc hydrometallurgy into the upper end of the recovery bin 1. The waste residue moves along the conical groove 3. The reciprocating lead screw 9 acts on the inner arc rod 5 and the outer arc rod 6, which not only plays a role in shrinking the diameter, but also drives the conical support 2 to rotate by the linkage motor 15 to grind the waste residue, avoiding the problem of low efficiency when large-particle waste residue undergoes the next decomposition operation. And after the waste residue is ground, the lower screening plate 13 in the chute screens and discharges the waste residue debris, making the grinding of the waste residue more comprehensive.
