[0002] Hydrometallurgical zinc smelting accounts for more than 80% of the total zinc smelting volume worldwide and represents the future direction of global zinc production. Hydrometallurgical zinc smelting processes mainly include: conventional hydrometallurgical zinc smelting process, high-temperature hot acid leaching process, and direct oxygen pressure leaching process of zinc sulfide concentrate. Among these, the direct oxygen pressure leaching process of zinc sulfide concentrate is currently the newest technology and the development trend in hydrometallurgical zinc smelting.

The striking component 5 can strike the feeding pipe 3, and the pressing component 6 can press the material.

[0030] The striking assembly 5 includes a toothed ring 51 disposed on the outside of the feeding pipe 3. The bottom of the toothed ring 51 is rotatably mounted on the top of the leaching tank 1, and movable gears 52 are meshed on the four sides of the inner cavity of the toothed ring 51. Rotating rods 53 are fixedly installed through the upper middle part of the movable gears 52, and the lower ends of the rotating rods 53 are movably mounted on the top of the leaching tank 1. Swing rods 54 are fixedly sleeved at the output ends of the rotating rods 53. An L-shaped plate 55 is disposed on the left side of the toothed ring 51. The bottom of the L-shaped plate 55 is fixedly mounted on the leaching tank 1, and a bearing plate 56 is fixedly mounted on the top of the L-shaped plate 55 near the rear side. A drive motor 57 is fixedly mounted on the rear side of the bearing plate 56. The output end of the drive motor 57 extends movably through to the outside of the L-shaped plate 55 and is fixedly mounted on a turntable 58. A connecting rod 59 is movably mounted on the bottom of the turntable 58 near the front side, which can drive the swing rods 54 to swing back and forth, which is conducive to the development of the striking work and speeds up the screening efficiency.

[0031] A striking ball 541 is fixedly installed at the end of the swing rod 54 away from the rotating rod 53. The striking ball 541 is not attached to the feeding pipe 3. Later, it can drive the striking ball 541 to swing back and forth to strike the feeding pipe 3, thereby accelerating the screening rate through vibration.

[0032] A sliding block 591 is movably installed at the rear end of the connecting rod 59, and the bottom of the sliding block 591 is slidably installed on the top of the leaching tank 1. A transmission rack plate 592 is fixedly installed on the front side of the sliding block 591 near the right side. A transmission gear 593 is meshed on the right side of the transmission rack plate 592, and the transmission gear 593 is fixedly sleeved on the adjacent rotating rod 53, which facilitates the development of transmission work.

[0033] A dryer 8 is fixedly installed on the right side of the leaching tank 1 near the bottom. A connecting pipe is fixedly installed on the top of the dryer 8. A blowing pipe 9 is fixedly installed on the left end of the connecting pipe. The left side of the blowing pipe 9 extends through the inner cavity of the leaching tank 1.

[0034] A handle 71 is fixedly installed in the middle of the front side of the collection tank 7, and a drain pipe 72 is fixedly installed through the middle of the bottom of the collection tank 7. A valve 73 is provided on the outside of the drain pipe 72, and an opening is opened on the front side of the middle of the bottom of the leaching tank 1.

[0035] In this embodiment: During use, the material can be added to the leaching tank 1 through the feeding pipe 3. The screening plate 4 in the feeding pipe 3 can screen the material, allowing smaller material particles to pass through the screening plate 4 and enter the collection tank 7. During feeding, the drive motor 57 can be run, which will drive the turntable 58 to rotate. When the turntable 58 rotates, it will drive the sliding block 591 to move back and forth through the connecting rod 59. When the sliding block 591 moves back and forth, it will drive the transmission rack plate 592 to move back and forth. The transmission gear 593 rotates back and forth in both directions.

When the gear ring 51 rotates, it drives the four movable gears 52 on all sides to rotate back and forth in both directions. This drives the adjacent swing rod 54 to rotate through the rotating rod 53. As a result, the ball 541 continuously strikes the feeding pipe 3 back and forth, and the vibration speed is increased.

[0036] Example 2

[0037] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1-7 and Figure 9The extrusion assembly 6 includes a servo motor 61 fixedly installed on the rear side of the leaching tank 1 near the lower right corner and a threaded rod 62 fixedly installed on the output end of the servo motor 61. A plate is movably installed on the upper end of the threaded rod 62, and the front side of the plate is fixedly installed on the leaching tank 1. A threaded sleeve 63 is threadedly installed on the output shaft of the threaded rod 62. The front side of the threaded sleeve 63 is slidably installed on the leaching tank 1, and an L-shaped rod 64 is fixedly installed in the middle of the rear side of the threaded sleeve 63. A movable plate 65 is fixedly installed on the upper end of the L-shaped rod 64. An extrusion plate 66 is provided near the middle of the inner cavity of the leaching tank 1. The extrusion plate 66 can be driven to move downward, thereby extruding the material entering the collection tank 7, further reducing the gap between the material particles, strengthening and improving the material sealing effect, and facilitating the development of zinc recovery leaching.

[0038] Two movable rods 651 are fixedly installed at the bottom of the movable plate 65 near the front side. The movable rods 651 are arranged front and back. The lower ends of the movable rods 651 slide through and extend into the inner cavity of the leaching tank 1, and are fixedly installed on the extrusion plate 66, so that the extrusion plate 66 can move synchronously when the movable plate 65 moves.

[0039] In this embodiment: after the material enters the collection tank 7, the leaching solution is injected through the feeding pipe 3 to leach the material particles in the collection tank 7. After the leaching is completed, the valve 73 is opened and the leaching solution is discharged through the drain pipe 72, while the particles remain in the collection tank 7. At this time, the servo motor 61 can be started. When the servo motor 61 runs, it drives the threaded rod 62 to rotate. When the threaded rod 62 rotates, it drives the threaded sleeve 63 to move downward. When the threaded sleeve 63 moves downward, it drives the movable plate 65 to move downward through the L-shaped rod 64. When the movable plate 65 moves downward, it drives the extrusion plate 66 to move downward through the movable rod 651, which can extrude the material particles in the collection tank 7, further reducing the gaps between the material particles, strengthening the material sealing effect, and facilitating the development of zinc recovery leaching. Later, the collection tank 7 can be pulled out by pulling the handle 71 to remove the material.

[0040] Working Principle: During use, materials can be added to the leaching tank 1 through the feeding pipe 3. The screening plate 4 in the feeding pipe 3 can screen the materials, allowing smaller particles to pass through the screening plate 4 and enter the collection tank 7. During feeding, the drive motor 57 can be activated, which in turn drives the turntable 58 to rotate. The rotation of the turntable 58 drives the sliding block 591 to move back and forth via the connecting rod 59. The back-and-forth movement of the sliding block 591 drives the transmission rack plate 592 to move back and forth, which in turn drives the transmission gear 593 to rotate in both directions. The rotation of the transmission gear 593 in both directions drives the adjacent rotating rod 53 to rotate in both directions. The rotation of the rotating rod 53 drives the adjacent movable gear 52 to rotate in both directions. The rotation of the movable gear 52 drives the gear ring 51 to rotate, which in turn drives the four movable gears 52 on all sides to rotate in both directions. This, in turn, drives the adjacent swing rod 54 to rotate via the rotating rod 53. By repeatedly striking the feeding pipe 3 with the striking ball 541, the screening rate is accelerated through vibration. After the material enters the collection tank 7, the leaching solution is injected through the feeding pipe 3 to leach the material particles in the collection tank 7. After the leaching is completed, the valve 73 is opened to discharge the leaching solution through the drain pipe 72, while the particles remain in the collection tank 7. At this time, the servo motor 61 is activated. When the servo motor 61 is running, it drives the threaded rod 62 to rotate. When the threaded rod 62 rotates, it drives the threaded sleeve 63 to move downward. When the threaded sleeve 63 moves downward, it drives the movable plate 65 to move downward through the L-shaped rod 64. When the movable plate 65 moves downward, it drives the extrusion plate 66 to move downward through the movable rod 651, which can extrude the material particles in the collection tank 7, further reducing the gaps between the material particles, enhancing the material sealing effect, and facilitating the zinc recovery leaching process. Finally, the collection tank 7 can be pulled out by pulling the handle 71 to remove the material.
