Abstract
Description
Technical Field
[0001] This utility model relates to the field of zinc pot slag removal technology in simulated hot-dip galvanizing experiments, specifically a bendable zinc pot slag removal device. Background Technology
[0002] In the industrial production process of hot-dip galvanized aluminum-magnesium alloys, the zinc pot plays a crucial role. The molten zinc inside provides the necessary zinc coating to the metal sheet, enhancing its corrosion resistance and service life. However, during use, scum inevitably forms on the surface of the molten zinc. This scum mainly consists of incompletely reacted metal oxides, impurities, and gaseous substances released from the molten zinc.
[0003] Since the zinc pot is in a closed vacuum chamber, it is impossible to clean the slag generated on the surface of the zinc liquid. Existing slag removal tools cannot bend at an angle, resulting in the inability to completely remove the zinc slag and poor slag removal effect. As a result, the surface slag adheres to the plate during the galvanizing process, affecting the surface quality of the coating. Therefore, we have proposed a bendable zinc pot slag removal device to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a bendable zinc pot slag removal device, which solves the problems mentioned in the background section.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0008] A bendable zinc pot slag removal device includes a shaft with a U-shaped groove at its end. A connecting rod is mounted on the U-shaped groove and threadedly connected to the U-shaped groove on the shaft via a first bolt. A retaining ring is welded to the end of the connecting rod, and a stainless steel filter screen is movably contacted on the retaining ring. A vertical rod is mounted on the top of the retaining ring. A circular groove is provided on the shaft, and a pull rod is slidably connected within the circular groove. A transmission rod is rotatably connected to the top of the vertical rod, and the end of the transmission rod is hinged to the end of the pull rod. A rectangular hole is provided on the inner wall of the top of the circular groove, and the inner wall of the rectangular hole does not contact the outer side of the transmission rod.
[0009] Furthermore, the top of the fixing ring is provided with a plurality of mounting grooves with one side open, and the bottom inner wall of the mounting groove is provided with a threaded groove.
[0010] Furthermore, a fixing block is movably contacted on the mounting groove, and one side of the fixing block is fixedly connected to one side of the stainless steel filter screen.

[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a bendable zinc pot slag removal device, which has the following beneficial effects:
[0015] This invention allows the user to first pull a lever, which slides within a circular groove on a shaft. This movement, via a transmission rod, moves a vertical rod, which in turn rotates a fixed ring and a connecting rod on a U-shaped groove. When the filter screen reaches the desired angle, a first bolt secures the connecting rod to the corresponding position in the U-shaped groove, ensuring the stability of the stainless steel filter screen's angle. This allows for adjustment of the stainless steel filter screen's angle, enabling it to rotate freely within a vacuum chamber for slag removal. By adjusting the angle, the user can more effectively remove slag from the zinc pot's surface. Different mesh sizes of stainless steel filter screens can be used, accommodating various plating solution compositions. Using this device, effective slag removal and cleaning of the zinc pot's surface within a vacuum chamber can be achieved, improving the purity of the zinc solution and the quality of the plating surface.

[0022] Example
[0023] like Figure 1-4 As shown, an embodiment of this utility model discloses a bendable zinc pot slag removal device, including a shaft 1. A U-shaped groove 2 is formed at the end of the shaft 1, and a connecting rod 4 is provided on the U-shaped groove 2. The connecting rod 4 is threadedly connected to the U-shaped groove 2 on the shaft 1 by a first bolt 3. A fixing ring 5 is welded to the end of the connecting rod 4, and a stainless steel filter screen 6 is movably contacted on the fixing ring 5. A vertical rod 7 is provided at the top of the fixing ring 5. A circular groove 8 is formed on the shaft 1, and a pull rod 9 is slidably connected within the circular groove 8. A transmission rod 10 is rotatably connected to the top of the vertical rod 7, and the end of the transmission rod 10 is hinged to the end of the pull rod 9. A rectangular hole 11 is formed on the inner wall of the top of the circular groove 8. The inner wall of the rectangular hole 11 does not contact the outer side of the transmission rod 10. The user first pulls the pull rod 9, and the pull rod 9... The filter screen slides within the circular groove 8 and moves the vertical rod 7 via the transmission rod 10. The movement of the vertical rod 7 further drives the fixing ring 5 and the connecting rod 4 to rotate on the U-shaped groove 2. When the filter screen reaches the required angle, the connecting rod 4 is fixed in the corresponding position of the U-shaped groove 2 using the first bolt 3, ensuring the stability of the angle of the stainless steel filter screen 6. This allows the angle of the stainless steel filter screen 6 to be adjusted, enabling it to rotate freely within the vacuum chamber for slag removal. By adjusting the angle of the stainless steel filter screen 6, the user can more effectively remove the floating slag from the surface of the zinc pot. Different mesh sizes of stainless steel filter screen 6 can also be replaced to accommodate various plating solution compositions. Through the use of this device, effective removal and cleaning of floating slag from the surface of the zinc pot within the vacuum chamber can be achieved, improving the purity of the zinc liquid and the surface quality of the plating layer.
[0024] In some embodiments, the top of the fixing ring 5 is provided with a plurality of mounting grooves 12 with one side open, and the bottom inner wall of the mounting groove 12 is provided with a threaded groove 13. The engagement of the threaded groove 13 with the second bolt 15 makes the fixing process more secure and reliable, and also facilitates the disassembly and replacement of the stainless steel filter screen 6.
[0025] In some embodiments, a fixing block 14 is movably contacted on the mounting groove 12, and one side of the fixing block 14 is fixedly connected to one side of the stainless steel filter screen 6. The fixing block 14 serves as a connection.
[0026] In some embodiments, the fixing block 14 is provided with a second bolt 15, which is threadedly connected to the corresponding threaded groove 13. The threaded connection is a very stable connection method. By rotating the second bolt 15, it can be tightly screwed into the threaded groove 13, thereby achieving a firm connection between the fixing block 14 and the mounting groove 12.
[0027] In some embodiments, the fixing block 14 is provided with a threaded hole, and the fixing block 14 is threadedly connected to the corresponding second bolt 15 through the threaded hole. The fixing block 14 serves to fix the device.
[0028] Working principle or structural principle: When adjusting the angle of the stainless steel filter screen 6, the user first pulls the pull rod 9. The pull rod 9 slides in the circular groove 8 of the shaft 1, and drives the vertical rod 7 to move through the transmission rod 10. The movement of the vertical rod 7 further drives the fixing ring 5 and the connecting rod 4 to rotate on the U-shaped groove 2. When the filter screen reaches the required angle, the first bolt 3 is used to fix the connecting rod 4 in the corresponding position of the U-shaped groove 2 to ensure the stability of the angle of the stainless steel filter screen 6, thereby allowing the angle of the stainless steel filter screen 6 to be adjusted. It can rotate freely in the vacuum chamber to remove slag. When replacing the stainless steel filter screen 6, the user first rotates the second bolt 15 to separate it from the threaded groove 13, then... Next, remove the stainless steel filter screen 6 from the mounting groove 12, and place another stainless steel filter screen 6 into the mounting groove 12 through the fixing block 14. Finally, use the second bolt 15 to connect with the corresponding threaded groove 13 to fix the other stainless steel filter screen 6 in the mounting groove 12. When performing slag removal operations in the vacuum chamber, the user can adjust the angle of the stainless steel filter screen 6 to make it more effective in removing the floating slag on the surface of the zinc pot. Stainless steel filter screens 6 with different mesh sizes can adapt to various plating solution compositions. Through the use of this device, the floating slag on the surface of the zinc pot in the vacuum chamber can be effectively removed and cleaned, improving the purity of the zinc liquid and the surface quality of the plating layer.
