After collection, the retrieval trough is reinstalled at the bottom of the connecting plate, and the ejector spring pushes the connecting pin out and inserts it into the inside of the connecting collar after the connecting collar passes through the through groove. Thus, the retrieval trough is fixed by the connecting collar, which allows for easy disassembly of the retrieval trough for convenient collection of the retrieved zinc dross.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example: Please refer to Figure 1-4 An automatic zinc slag removal device for a galvanizing production line includes a galvanizing tank 1, a support frame 2 fixedly connected to the top of the galvanizing tank 1, the center line of the galvanizing tank 1 and the center line of the support frame 2 are on the same vertical plane, and the support frame 2 is provided with a lifting structure for automatically controlling the lifting of the removal structure.
[0026] The lifting structure includes a mounting cylinder 10. The mounting cylinder 10 is movably connected to the left side of the top of the support frame 2. A cylinder 12 is fixedly connected to the top of the mounting cylinder 10. A connecting plate 15 is provided at the bottom of the mounting cylinder 10.

[0027] The output end of cylinder 12 is fixedly connected to connecting plate 15, and the limiting cylinder 11 is movably connected to galvanizing tank 1;
[0028] Specifically, such as Figure 1 and Figure 3 As shown, before retrieval, the cylinder 12 inside the mounting cylinder 10 is activated. The cylinder 12 pushes the retrieval trough 13 at the bottom down through the connecting plate 15, sending the retrieval trough 13 into the galvanizing pool 1 for retrieval of zinc slag. After retrieval, the cylinder 12 is activated again to lift the retrieval trough 13 through the connecting plate 15, facilitating material removal and subsequent galvanizing. The limiting cylinder 11 at the top of the connecting plate 15 fits against the outside of the mounting cylinder 10, which can limit the connection plate 15 and the retrieval trough 13 to ensure stability during the lifting process, thus realizing automatic control of the lifting of the retrieval trough 13.
[0029] A fixed cover 3 is fixedly connected to the top of the support frame 2. A threaded shaft 4 is movably connected inside the fixed cover 3. A threaded sleeve 5 is movably connected to the left side of the threaded shaft 4. A sliding groove 17 is opened at the top of the support frame 2. A connecting block 16 is fixedly connected to the bottom end of the threaded sleeve 5. A drive motor 6 is fixedly connected to the left side of the top of the fixed cover 3. A first transmission wheel 8 is fixedly connected to the output end of the drive motor 6. A transmission belt 7 is movably connected to the outside of the first transmission wheel 8. A second transmission wheel 9 is fixedly connected to one side of the threaded shaft 4 that passes through the fixed cover 3.
[0030] The connecting block 16 is fixedly connected to the mounting cylinder 10 through the sliding groove 17, and the connecting block 16 is slidably connected to the sliding groove 17.
[0031] The transmission belt 7 is movably connected to the second transmission wheel 9, and the center line of the first transmission wheel 8 and the center line of the second transmission wheel 9 are on the same vertical plane;
[0032] Specifically, such as Figure 1 and Figure 2 As shown, during the retrieval process, after the retrieval trough 13 is sent into the galvanizing tank 1, the drive motor 6 is started to drive the first transmission wheel 8 to rotate. The first transmission wheel 8 drives the second transmission wheel 9 to rotate through the transmission belt 7. The second transmission wheel 9 drives the threaded shaft 4 to rotate, while simultaneously driving the threaded sleeve 5 outside it to move to one side. Finally, the threaded sleeve 5 drives the retrieval trough 13 at the bottom to move to one side through the connecting block 16 to automatically retrieve the zinc slag inside the galvanizing tank 1. This achieves automatic control of the movement of the retrieval trough 13 to quickly retrieve the zinc slag.
[0033] The bottom end of the connecting plate 15 is movably connected to the retrieval trough 13. The left side inside the retrieval trough 13 is fixedly connected to the drainage net 14. The two ends of the top of the connecting plate 15 are fixedly connected to the fixing cylinder 18. The two ends of the top of the retrieval trough 13 are fixedly connected to the connecting collar 20. The two ends of the top of the connecting plate 15 are provided with through grooves 22. The connecting collar 20 passes through the through grooves 22 and extends to the top of the connecting plate 15. The side inside the fixing cylinder 18 is fixedly connected to the ejector spring 19. The side of the ejector spring 19 is fixedly connected to the connecting pin 21.

[0035] The centerline of the connecting collar 20 and the centerline of the fixed cylinder 18 are on the same vertical plane, and the centerline of the dredging trough 13 and the centerline of the drainage net 14 are on the same vertical plane;
[0036] Specifically, such as Figure 1 , Figure 3 and Figure 4As shown, after the retrieval trough 13 is raised after the retrieval is completed, the connecting pins 21 at both ends of the top of the connecting plate 15 are pushed to disengage it from the inside of the connecting collar 20. Then, the retrieval trough 13 can be pulled to remove it from the bottom of the connecting plate 15 to facilitate the collection of zinc dross retrieved from inside the retrieval trough 13. After collection, the retrieval trough 13 is reinstalled at the bottom of the connecting plate 15. After the connecting collar 20 passes through the through groove 22, the spring 19 pushes out and inserts the connecting pins 21 into the inside of the connecting collar 20, thereby fixing the retrieval trough 13 through the connecting collar 20. This allows for easy disassembly of the retrieval trough 13 to facilitate the collection of the retrieved zinc dross.
[0037] Working Principle: In use, before retrieval, the cylinder 12 inside the mounting cylinder 10 is activated. The cylinder 12, through the connecting plate 15, pushes the retrieval trough 13 at the bottom downwards, sending it into the galvanizing pool 1 for zinc slag retrieval. After retrieval, the cylinder 12 is activated again, through the connecting plate 15, to raise the retrieval trough 13, facilitating material removal and subsequent galvanizing. The limiting cylinder 11 at the top of the connecting plate 15, fitted to the outside of the mounting cylinder 10, limits the connection plate 15 and the retrieval trough 13, ensuring stability during lifting. During retrieval, after the retrieval trough 13 is sent into the galvanizing pool 1, the drive motor 6 is activated, driving the first transmission wheel 8 to rotate. The first transmission wheel 8, through the transmission belt 7, drives the second transmission wheel 9 to rotate. The drive wheel 9 drives the threaded shaft 4 to rotate, while simultaneously moving the threaded sleeve 5 on its outside to one side. Finally, the threaded sleeve 5 drives the bottom scooping trough 13 to one side through the connecting block 16 to automatically scoop the zinc dross inside the galvanizing pool 1. After the scooping is completed and the scooping trough 13 is raised, the connecting pins 21 at both ends of the top of the connecting plate 15 are pushed to disengage it from the inside of the connecting collar 20. Then, the scooping trough 13 can be pulled to remove it from the bottom of the connecting plate 15 to facilitate the collection of the zinc dross scooped from inside the scooping trough 13. After collection, the scooping trough 13 is reinstalled at the bottom of the connecting plate 15, and the connecting collar 20 passes through the through groove 22 and pushes out the spring 19 to push out the connecting pin 21 and insert it into the inside of the connecting collar 20, thereby fixing the scooping trough 13 through the connecting collar 20.
