Description

Technical Field

[0001] This invention relates to the field of steel pipe galvanizing technology, specifically to a multi-specification galvanizing airflow and zinc layer stability control device. Background Technology

[0002] During the production and processing of steel pipes, galvanizing is required to form a dense zinc layer on the surface, achieving long-term corrosion and rust prevention, thereby extending the service life of the steel pipes and improving their economic efficiency. A zinc layer stabilization control device is needed during the galvanizing process. This device adjusts parameters such as the air pressure of the air knife to achieve stable control of the galvanizing airflow and the zinc layer. For example, Chinese utility model patent application No. 202020247625.9, filed on March 4, 2020, describes a galvanizing layer thickness control device, which includes a base plate. This device solves the problem of only being able to detect the galvanizing thickness of the product, but not truly controlling it. Another example is Chinese invention patent application No. 202210229137.9, filed on March 10, 2022, which describes an automatic zinc layer thickness control device, including a support mechanism, a scraping mechanism, an adjusting mechanism, and a sliding mechanism. The zinc pot, control mechanism, and annealing furnace, during operation, allow the scraping mechanism to automatically adjust the distance between the two blades in the two scraping mechanisms through the action of the sliding mechanism. This facilitates the control of the zinc layer thickness scraping on the side wall of the strip steel, effectively reducing the labor intensity of operators and improving production efficiency. The equipment replaces manual adjustment of the air knife, significantly reducing the workload of operators. Also included is Chinese utility model patent application number 202323455902.8, filed on 2023-12-19, which discloses a zinc layer thickness control device for galvanized steel wire. This device includes a steel wire galvanizing mechanism that, during operation, can regulate the thickness of the galvanized layer. This allows for adjusting the length of the steel wire inserted into the galvanizing solution according to the galvanizing requirements, thereby adjusting the thickness of the galvanized layer. It can also regulate the galvanized layer thickness by cooling and adjusting the steel wire winding rate, improving the galvanizing effect and enabling more accurate and efficient control of the galvanized layer thickness, thus improving the production quality of galvanized steel wire.

[0003] When the air knife is working, it will forcibly peel off the zinc dross on the surface of the workpiece, and then zinc dross will fall off. However, the device in the above application does not have a structure for rapid cleaning of zinc dross during use. As a result, after a long period of use, there will be a lot of zinc dross inside the zinc liquid, which will affect the subsequent operation of the zinc layer stability control device. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-specification galvanizing airflow and zinc layer stabilization control device to solve the problem mentioned in the background art that it does not have a structure for rapid zinc dross removal, and therefore, after long-term use, there is a lot of zinc dross inside the zinc liquid, which will affect the subsequent operation of the zinc layer stabilization control device.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A multi-specification galvanizing airflow and zinc layer stabilization control device includes a base plate. A bracket is bolted to the upper surface of the base plate, and the bracket is movably connected to an equipment plate via an electric slide rail. A clamping module is located at the lower end of the equipment plate, and an air knife module is located on the lower surface of the equipment plate. A material box is bolted to the upper surface of the base plate, and a connecting shaft is rotatably mounted inside the material box. A stirring blade is fixedly connected to the surface of the connecting shaft. Connecting plates are fixedly connected to both sides of the material box, and the connecting plates are connected to movable rods via reversing components. A filter plate is movably mounted inside the movable rods. A guide plate is fixedly connected to the surface of the material box, and the guide plate is connected to a push rod via a lifting component.

[0007] Preferably, the connecting shaft passes through the interior of the material box, and a first gear is fixedly connected to the surface of the connecting shaft. A rack is fixedly connected to the lower surface of the equipment plate, and the rack is meshed with the first gear.

[0008] Preferably, the stirring blades are evenly distributed on the surface of the connecting shaft, and the connecting shaft is symmetrically distributed on both sides of the material box.

[0009] Preferably, the movable rods are symmetrically distributed on both sides of the material box. The reversing assembly includes a rotating shaft rotatably disposed inside the connecting plate on the left side, and the rotating shaft is threadedly connected to the movable rod on the left side. The threads on both sides of the rotating shaft rotate in opposite directions. A long pin is fixedly connected inside the connecting plate on the right side, and the surface of the long pin is slidably connected to the movable rod on the right side.

[0010] Preferably, a limiting rod is slidably provided inside the bracket, and a fixing plate is fixedly connected to the lower surface of the limiting rod, and a limiting plate is fixedly connected to the upper surface of the limiting rod, and the limiting plate is located on the upper surface of the bracket.

[0011] Preferably, a lower connecting rod is fixedly connected to the lower surface of the fixed plate, and toothed blocks are evenly spaced on the surface of the lower connecting rod. A second gear is fixedly connected to the surface of the rotating shaft, and the front of the movable rod is viewed as an inverted "L" structure.

[0012] Preferably, the filter plates are symmetrically distributed on both sides of the material box, and the filter plates are inclined.

[0013] Preferably, the lifting assembly includes a sliding plate sleeved and connected to the surface of the guide plate, and both sides of the guide plate are protruding. A spring shock absorber is fixedly connected to the upper surface of the sliding plate, and the other side of the spring shock absorber is fixedly connected to the lower surface of the guide plate. A circular plate is fixedly connected to the surface of the connecting shaft, and a push block is fixedly connected to the surface of the circular plate.

[0014] Preferably, the push blocks are evenly distributed on the surface of the circular plate, and the surface of the push blocks is arc-shaped. The push rods are fixedly connected at equal intervals on the upper surface of the slide plate, and the initial end of the push rod is lower than the lower surface of the filter plate.

[0015] Preferably, the movable rod has an inner shaft that is rotatably provided inside, and the filter plate is fixedly connected to the surface of the inner shaft, and a stop bar is fixedly connected to the surface of the movable rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] Employing a novel structural design, the slowly rotating stirring blades gently agitate the material bin, preventing zinc dross from settling. Simultaneously, after the equipment plate rises to the top, the filter plate covers the material bin, preventing zinc dross from entering. During its movement, the filter plate oscillates under the influence of the push rod and its own gravity, allowing it to quickly discharge the zinc dross. The specific details are as follows:

[0018] (1) When the multi-specification galvanizing airflow and zinc layer stabilization control device is working, the steel pipe is sleeved on the clamping roller, and then the clamping roller is clamped by the clamping module. After that, the equipment plate descends, so that the workpiece enters the material box. After galvanizing, the equipment plate rises. During the process of the equipment plate rising and falling, the connecting shaft rotates slowly inside the material box under the action of the first gear and rack. Then, the equally spaced stirring blades can slightly stir the zinc liquid, so that the zinc liquid shakes and the zinc dross floats up quickly, preventing the zinc dross from settling.

[0019] (2) When the equipment plate rises, the multi-specification galvanizing airflow and zinc layer stabilization control device will eventually contact the fixed plate. After that, the equipment plate continues to rise, and the fixed plate is pushed up. At this time, the fixed plate drives the rotating shaft to rotate inside the connecting plate through the lower connecting rod and the second gear. Then, the movable rod moves closer to each other under the action of the long pin and the rotating shaft and moves towards the middle of the material box. Finally, the filter plate will cover the material box, so that when the air knife is working, the zinc dross discharged by the workpiece will not enter the inside of the material box, making the inside of the material box cleaner and not affecting the subsequent work of the material box.

[0020] Furthermore, the filter plates are inclined, which allows the zinc dross to fall off quickly under its own gravity, improving work efficiency.

[0021] (3) During the process of the equipment plate rising and falling, when the connecting shaft rotates, the connecting shaft will drive the circular plate and the push block to rotate synchronously. Then the push block will intermittently push the slide plate, so that the slide plate will drive the push rod to make reciprocating linear motion in the vertical direction under the action of the thrust, the guide plate and the spring damper. At this time, the filter plate and the inner shaft are in a swinging state on the side of the moving rod under the action of the thrust and their own gravity, which can better discharge the zinc dross.

[0022] Furthermore, during the swinging process of the filter plate, the stop rod plays a limiting role, preventing the filter plate from swinging downwards too much. At the same time, when the equipment plate initially rises, the push rod works, at which point the filter plate is located on both sides of the material box. However, when the equipment plate continues to rise after contacting the fixed plate, the push rod does not work. At this point, the highest position of the push rod is at the lower end of the filter plate, which does not affect the horizontal movement of the filter plate. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-12 The present invention provides the following technical solution: a multi-specification galvanizing airflow and zinc layer stabilization control device.

[0038] Example 1: The slowly rotating stirring blades 8 allow the molten zinc inside the material tank 4 to slosh gently, promoting better floating of the zinc dross. Figures 1-4 As shown, the device includes a base plate 1, a bracket 2 bolted to the upper surface of the base plate 1, and a device plate 3 movably connected to the bracket 2 via an electric slide rail. A clamping module is provided at the lower end of the device plate 3, and an air knife module is provided on the lower surface of the device plate 3. A material box 4 is bolted to the upper surface of the base plate 1, and a connecting shaft 5 is rotatably provided inside the material box 4. A stirring blade 8 is fixedly connected to the surface of the connecting shaft 5. The connecting shaft 5 passes through the interior of the material box 4, and a first gear 6 is fixedly connected to the surface of the connecting shaft 5. A rack 7 is fixedly connected to the lower surface of the device plate 3, and the rack 7 and the first gear 6 are meshed. The stirring blades 8 are evenly distributed on the surface of the connecting shaft 5, and the connecting shaft 5 is symmetrically distributed on both sides of the material box 4.

[0039] During operation, the steel pipe is sleeved on the clamping roller, and then the clamping roller is held by the clamping module. Afterwards, the equipment plate 3 descends inside the support 2 via the electric slide rail, allowing the workpiece to enter the material box 4. After galvanizing, the equipment plate 3 rises and is processed by the air knife, realizing airflow control and zinc layer control. During the rising and falling of the equipment plate 3, the rack 7 moves synchronously, and the connecting shaft 5 rotates slowly inside the material box 4 under the action of the first gear 6 and the rack 7. The stirring blades 8 evenly distributed on the surface of the connecting shaft 5 can slightly agitate the zinc liquid, causing the zinc liquid to slosh, so that the zinc dross can float better inside the material box 4.

[0040] Example 2: Unlike Example 1, by using a reversing assembly, the filter plate 15 can reciprocate linearly on the upper surface of the material box 4, thereby covering the material box 4 and preventing zinc dross from entering its interior. Figures 4-8 As shown, connecting plates 13 are fixedly connected to both sides of the material box 4, and the connecting plates 13 are connected to movable rods 18 through reversing components, and filter plates 15 are movably arranged inside the movable rods 18.

[0041] The movable rods 18 are symmetrically distributed on both sides of the material box 4. The reversing assembly includes a rotating shaft 14 rotatably disposed inside the left connecting plate 13. The rotating shaft 14 is threadedly connected to the left movable rod 18, and the threads on both sides of the rotating shaft 14 are in opposite directions. A long pin 17 is fixedly connected inside the right connecting plate 13, and the surface of the long pin 17 is slidably connected to the right movable rod 18. A limit rod 9 is slidably disposed inside the bracket 2. A fixing plate 10 is fixedly connected to the lower surface of the limit rod 9, and a limit plate 11 is fixedly connected to the upper surface of the limit rod 9. The limit plate 11 is located on the upper surface of the bracket 2.

[0042] The lower surface of the fixed plate 10 is fixedly connected to the lower connecting rod 12, and the surface of the lower connecting rod 12 is provided with toothed blocks at equal intervals. The surface of the rotating shaft 14 is fixedly connected to the second gear 26. The front of the movable rod 18 is an inverted "L" structure. The filter plates 15 are symmetrically distributed on both sides of the material box 4, and the filter plates 15 are inclined.

[0043] When the equipment plate 3 rises, the workpiece is lifted by the clamping module. The fixed plate 10 only begins to rise when the equipment plate 3 contacts the fixed plate 10. (Before moving, the fixed plate 10 remains stable under the action of the limiting rod 9 and the limiting plate 11, such as...) Figure 4 and Figure 7As shown), at this time, the fixed plate 10 drives the rotating shaft 14 to rotate inside the connecting plate 13 through the gear and the second gear 26 on the surface of the lower connecting rod 12. When the rotating shaft 14 rotates, it will cooperate with the long pin 17, causing the movable rod 18 to drive the filter plate 15 to slide. The filter plate 15 moves to the middle position of the material box 4. Finally, the filter plate 15 covers the material box 4, preventing zinc dross from falling into the inside of the material box 4. During the process of the equipment plate 3 descending, the rotating shaft 14 immediately reverses. At this time, the movable rod 18 and the filter plate 15 move back, causing the material box 4 to open again, so as not to affect the next galvanizing operation.

[0044] Example 3: Unlike Example 2, the lifting assembly allows the push rod 23 to reciprocate linearly in the vertical direction, thereby causing the filter plate 15 to swing, quickly shaking off the zinc dross. Figures 9-12 As shown, a guide plate 16 is fixedly connected to the surface of the material box 4, and a push rod 23 is connected to the guide plate 16 through a lifting assembly. The lifting assembly includes a slide plate 19 sleeved and connected to the surface of the guide plate 16, and both sides of the guide plate 16 are protruding. A spring shock absorber 22 is fixedly connected to the upper surface of the slide plate 19, and the other side of the spring shock absorber 22 is fixedly connected to the lower surface of the guide plate 16. A circular plate 20 is fixedly connected to the surface of the connecting shaft 5, and a push block 21 is fixedly connected to the surface of the circular plate 20.

[0045] Push blocks 21 are evenly distributed on the surface of the circular plate 20, and the surface of the push blocks 21 is arc-shaped. Push rods 23 are fixedly connected at equal intervals on the upper surface of the slide plate 19, and the initial end of the push rods 23 is lower than the lower surface of the filter plate 15. The movable rod 18 is provided with an inner shaft 24 for rotation, and the surface of the inner shaft 24 is fixedly connected to the filter plate 15. The surface of the movable rod 18 is also fixedly connected to a stop rod 25.

[0046] During the rising and falling of the equipment plate 3, when the rack 7 and the first gear 6 mesh, the connecting shaft 5 is in a rotating state. When the connecting shaft 5 rotates, it drives the circular plate 20 and the push block 21 to rotate synchronously. As a result, the push block 21 will intermittently push the slide plate 19. When the slide plate 19 is pushed, it slides on the surface of the guide plate 16. At this time, the spring damper 22 is squeezed. When the slide plate 19 is not pushed, it falls under its own weight and the action of the spring damper 22. Repeating the above process, the slide plate 19 intermittently pushes the filter plate 15 through the push rod 23, causing the filter plate 15 and the inner shaft 24 to swing under the action of the thrust and its own weight. As a result, the filter plate 15 can quickly shake off its own zinc dross, which can better prepare for subsequent work. At the same time, the filter plate 15 is inclined, which also optimizes the dross discharge effect. During the rotation of the inner shaft 24 and the filter plate 15, the stop rod 25 plays a positioning role to prevent the filter plate 15 from rotating too much.

[0047] When the equipment plate 3 initially rises, it does not contact the fixed plate 10. At this time, the connecting shaft 5 is rotating, while the rotating shaft 14 is not working. That is, when the connecting shaft 5 rotates at this time, the filter plate 15 is located on both sides of the material box 4. When the equipment plate 3 initially descends, the rack 7 has not yet engaged with the first gear 6. That is, when the rotating shaft 14 rotates, it drives the filter plate 15 to move to both sides of the material box 4. However, the connecting shaft 5 does not rotate at this time. Only when the rack 7 and the first gear 6 are engaged will the connecting shaft 5 start to reverse. When the rack 7 and the first gear 6 are engaged, the filter plate 15 has returned to both sides of the material box 4. That is, only when the filter plate 15 is located on both sides of the material box 4 will the filter plate 15 fall off. When the zinc dross falls off, it will only be discharged on the outside of the material box 4. The surface of the material box 4 is provided with a diversion plate with an inclined structure to facilitate the collection of impurities.

[0048] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
