Description

Technical Field

[0001] This utility model relates to the field of hot-dip galvanizing technology for aluminum-zinc alloy products, specifically a hot-dip galvanizing apparatus for preparing aluminum-zinc alloy products. Background Technology

[0002] Hot-dip aluminum-zinc alloy galvanizing is a common and effective method of metal corrosion protection, mainly used in metal structures in various industries. It involves immersing rust-removed steel parts in molten aluminum-zinc alloy at around 500°C, causing an aluminum-zinc alloy layer to adhere to the surface of the steel components, thereby achieving the purpose of corrosion protection.

[0003] A search revealed a hot-dip galvanizing device with application number 202211598217.8. This device uses the rotation of a motor output shaft to drive a first threaded rod, which in turn moves a filter plate upwards. The filter plate moves above the molten zinc, and the molten zinc flows back into the storage tank through the drain hole. Iron slag remains on the filter plate, and a cleaning component cleans the iron slag off the filter plate. Removing iron slag from the machine body is relatively convenient and helps ensure the galvanizing effect of steel products. However, the screw in this device is in the molten zinc for a long time, and the screw will also be coated with a layer of zinc, which will prevent the filter plate from moving on the screw, thus affecting the upward movement of the filter plate. At the same time, when the motor drives the first bevel gear to move upwards and mesh with the second bevel gear, it cannot be guaranteed that the tooth grooves of the first bevel gear and the second bevel gear can mesh precisely without misalignment, thus failing to achieve the desired removal effect of steel slag from the molten zinc. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a hot-dip galvanizing apparatus for preparing aluminum-zinc alloy products, so as to solve the technical problems in the background art mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot-dip galvanizing device for preparing aluminum-zinc alloy products, comprising a hot-dip galvanizing tank, wherein a preheating tank and a storage tank are provided inside the hot-dip galvanizing tank, a filter plate is connected inside the storage tank, a hanging ear is installed on the top of the filter plate, mounting frames are connected to both sides of the top of the hot-dip galvanizing tank, a hydraulic cylinder is connected to one side of one of the mounting frames, two winding rods are connected between the two mounting frames, a fixing frame is connected inside the two mounting frames, a guide rod and a lead screw are connected between the two fixing frames, a motor is installed at the bottom of one of the fixing frames, and the output end of the motor is connected to the lead screw, a first friction wheel is connected to one end of the lead screw, a slide is connected to the outside of the lead screw and the guide rod, a second friction wheel is connected to one side of the other mounting frame through a rotating rod, and two first synchronous pulleys are connected to the outside of the rotating rod, a traction rope is connected between the outside of the two winding rods and the hanging ear, a second synchronous pulley is connected to one side of each of the two winding rods, and a synchronous belt is connected between the second synchronous pulley and the first synchronous pulley.

[0006] Furthermore, two sets of heating mechanisms are installed between the hot-dip galvanizing tank and the preheating tank and the storage tank, and the two sets of heating mechanisms have different heating temperatures.

[0007] By adopting the above technical solution, the internal temperature of the preheating tank is controlled at 100-150 degrees Celsius, and the internal temperature of the storage tank is controlled at 450-500 degrees Celsius. With the cooperation of hydraulic cylinder and motor, the workpiece to be plated is immersed in the preheating tank and heated to near the temperature of zinc liquid. Then, driven by the slide, the heated workpiece is quickly transferred to the storage tank for hot plating. This avoids the zinc liquid from solidifying due to a sudden drop in temperature when the workpiece is immersed in the zinc liquid, which would affect the quality of the coating.

[0008] Furthermore, the mounting bracket has a sliding groove inside, and the fixing bracket is slidably connected to the mounting bracket.

[0009] By adopting the above technical solution, the staff starts the hydraulic cylinder, and through the limit of the slide groove, the output end of the hydraulic cylinder drives the fixed frame to move up or down, thereby driving the motor, guide rod and lead screw to move up or down, so that the slide can carry the workpiece to be plated into or out of the preheating tank or the liquid storage tank. By starting the motor to rotate forward or reverse, and guided by the guide rod, the slide can carry the workpiece to be plated between the preheating tank and the liquid storage tank.

[0010] Furthermore, the bottom of the carriage is connected to two clamps, which are made of 304 stainless steel.

[0011] By adopting the above technical solution, the clamp is U-shaped, which is existing technology. You can refer to the U-shaped clamp of Shenzhen Haosheng Stainless Steel Products Co., Ltd. 304 stainless steel does not easily react with aluminum-zinc alloy solution. By using a clamp made of 304 stainless steel to hold and fix the workpiece to be plated, the clamp can be prevented from being corroded, thereby extending the service life of the clamp.

[0012] Furthermore, the filter plate is made of ceramic.

[0013] By adopting the above technical solutions, ceramic filter plates have the characteristics of high temperature resistance, corrosion resistance, and high-precision filtration. They effectively remove impurities such as steel slag, which can not only improve coating quality and production efficiency, but also reduce energy consumption and extend equipment life.

[0014] Furthermore, the first friction wheel comes into contact with the second friction wheel.

[0015] By adopting the above technical solution, when it is necessary to process the steel slag inside the storage tank, the hydraulic cylinder is activated. The output end of the hydraulic cylinder drives the fixed frame to move to the highest point, so that the first friction wheel contacts the second friction wheel. At this time, the motor is activated. Under the drive of the motor output end, the lead screw drives the first friction wheel to rotate. Through the transmission between the first and second friction wheels, the rotating rod rotates. Through the transmission of the first synchronous pulley, the second synchronous pulley and the synchronous belt, the two winding rods rotate simultaneously and wind up the traction rope, thereby pulling the filter plate out of the storage tank and making it convenient for the staff to clean the steel slag on the filter plate.

[0016] Furthermore, the timing belt meshes with the first timing pulley and the second timing pulley, respectively.

[0017] By adopting the above technical solution, when the filter plate is reset after cleaning, the motor is started in reverse, causing the lead screw to drive the first friction wheel to rotate, which in turn causes the second friction wheel to drive the rotating rod to rotate. Under the drive of the rotating rod, the first and second synchronous pulleys are engaged by the synchronous belt, thereby driving the two winding rods to rotate in opposite directions at the same time, releasing the traction rope. Under the action of the filter plate's own gravity, it goes deep into the liquid storage tank and returns to its original position.

[0018] Furthermore, the traction rope is made of 310S stainless steel and has a ceramic coating on its surface.

[0019] By adopting the above technical solutions, the traction rope made of 310S stainless steel has better corrosion resistance than ordinary stainless steel. It is not easy to oxidize and peel in aluminum-zinc alloy liquid. At the same time, the ceramic coating can form a high-temperature and corrosion-resistant barrier on the surface of the traction rope, preventing the metal substrate from directly contacting the lead-zinc liquid, thereby further enhancing the corrosion resistance of the traction rope and extending its service life.

[0020] Furthermore, one end of the traction rope is connected to a hanging rod, and the hanging rod is detachably connected to the hanging lug.

[0021] By adopting the above technical solution, the staff pushes the filter plate to detach the hanging ear on one side from the hanging rod, and then supports the filter plate to detach the hanging ear on the other side from the hanging rod, thus removing the filter plate. This eliminates the need for the staff to remove the four sets of traction ropes separately to remove the filter plate, making the method simple and quick.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model is equipped with a winding rod, a traction rope, a filter plate, a first synchronous pulley, a second synchronous pulley, and a synchronous belt. When it is necessary to clean the steel slag inside the aluminum-zinc alloy solution, the hydraulic cylinder is activated. The output end of the hydraulic cylinder drives the fixed frame to move to the highest point. Under the drive of the motor output end, the first friction wheel contacts the second friction wheel, causing the rotating rod to drive the two first synchronous pulleys to rotate. Through the synchronous belt, the two second synchronous pulleys drive the winding rod to rotate simultaneously, winding up the traction rope. The traction rope causes the filter plate to rise and separate from the aluminum-zinc alloy solution. After the filter plate cools down, the filter plate is removed to clean the steel slag. The above method ensures the removal effect of steel slag.

[0024] 2. This utility model is equipped with a heating mechanism, a preheating tank, and a storage tank. The heating mechanism heats and maintains the temperature in the preheating tank and the storage tank at a certain temperature. With the cooperation of a hydraulic cylinder and a motor, the workpiece to be plated is immersed in the preheating tank and heated to near the temperature of the zinc liquid. Then, driven by a slide, the heated workpiece is quickly transferred to the storage tank for hot plating. This avoids the zinc liquid from solidifying due to a sudden drop in temperature when the workpiece is immersed in the zinc liquid, which would affect the quality of the plating layer.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] Example 1: A hot-dip galvanizing apparatus for preparing aluminum-zinc alloy products, such as... Figures 1-4 As shown, the system includes a hot-dip galvanizing tank 1, which contains a preheating tank 2 and a liquid storage tank 3. A filter plate 21 is connected inside the liquid storage tank 3, and a hanging lug 22 is installed on the top of the filter plate 21. Mounting brackets 5 are connected to both sides of the top of the hot-dip galvanizing tank 1. A hydraulic cylinder 6 is installed on one side of one of the mounting brackets 5. Two winding rods 17 are connected between the two mounting brackets 5. Fixing brackets 7 are connected inside the two mounting brackets 5. A guide rod 10 and a lead screw 9 are connected between the two fixing brackets 7. A motor 8 is installed at the bottom of one fixing bracket 7, and the output end of the motor 8 is connected to the lead screw 9. A first friction wheel 13 is connected to one end of the lead screw 9. A slide 11 is connected to the outside of the lead screw 9 and the guide rod 10. A second friction wheel 15 is connected to one side of the other mounting bracket 5 via a rotating rod 14, and two first synchronous pulleys 16 are connected to the outside of the rotating rod 14. The two winding rods 17 are connected to the outside of... A traction rope 20 is connected to the lug 22. A second synchronous pulley 18 is connected to one side of each of the two winding rods 17. A synchronous belt 19 is connected between the second synchronous pulley 18 and the first synchronous pulley 16. Two sets of heating mechanisms 4 are installed between the hot-dip galvanizing tank 1, the preheating tank 2, and the storage tank 3. The two sets of heating mechanisms 4 have different heating temperatures (the specific type of heating mechanism 4 is resistance heating). The internal temperature of the preheating tank 2 is controlled at 100-150 degrees Celsius, and the internal temperature of the storage tank 3 is controlled at 450-500 degrees Celsius. With the cooperation of the hydraulic cylinder 6 and the motor 8, the workpiece to be plated is immersed in the preheating tank 2 and heated to near the temperature of the zinc liquid. Then, driven by the slide 11, the heated workpiece is quickly transferred to the storage tank 3 for hot-dip galvanizing. This avoids the zinc liquid from solidifying due to a sudden drop in temperature when the workpiece is immersed in the zinc liquid, which would affect the quality of the coating.

[0033] See Figures 1-4 In the above embodiment, the mounting frame 5 is provided with a sliding groove, and the fixed frame 7 is slidably connected to the mounting frame 5. When the operator starts the hydraulic cylinder 6, the fixed frame 7 is moved up or down by the sliding groove limit. This causes the motor 8, guide rod 10 and lead screw 9 to move up or down, so that the slide 11 can move the workpiece to be plated into or out of the preheating tank 2 or the liquid storage tank 3. By starting the motor 8 to rotate forward or reverse, and guided by the guide rod 10, the slide 11 can move the workpiece to be plated between the preheating tank 2 and the liquid storage tank 3.

[0034] See Figures 1-4In the above embodiment, the bottom of the slide 11 is connected to two clamps 12, and the clamps 12 are made of 304 stainless steel. The clamps 12 are U-shaped, which is the prior art. You can refer to the U-shaped clamps 12 of Shenzhen Haosheng Stainless Steel Products Co., Ltd. 304 stainless steel does not easily react with aluminum-zinc alloy solution. By clamping and fixing the workpiece to be plated by the clamps 12 made of 304 stainless steel, the clamps 12 can be prevented from being corroded, thereby extending the service life of the clamps 12.

[0035] See Figure 3 and Figure 4 In the above embodiments, the filter plate 21 is made of ceramic. The ceramic filter plate 21 has the characteristics of high temperature resistance, corrosion resistance and high-precision filtration. The filter plate 21 effectively removes impurities such as steel slag. It can not only improve the coating quality and production efficiency, but also reduce energy consumption and extend the equipment life.

[0036] See Figure 2 and Figure 4 In the above embodiment, the first friction wheel 13 is in contact with the second friction wheel 15. When it is necessary to process the steel slag inside the storage tank 3, the hydraulic cylinder 6 is activated. The output end of the hydraulic cylinder 6 drives the fixed frame 7 to move up to the highest point, so that the first friction wheel 13 is in contact with the second friction wheel 15. At this time, the motor 8 is activated. Under the drive of the output end of the motor 8, the lead screw 9 drives the first friction wheel 13 to rotate. Through the transmission between the first friction wheel 13 and the second friction wheel 15, the rotating rod 14 rotates. Through the transmission of the first synchronous wheel 16, the second synchronous wheel 18 and the synchronous belt 19, the two winding rods 17 rotate at the same time and wind up the traction rope 20, thereby pulling the filter plate 21 out of the storage tank 3 and making it convenient for the staff to clean the steel slag on the filter plate 21.

[0037] See Figure 2 and Figure 3 In the above embodiment, the synchronous belt 19 engages with the first synchronous pulley 16 and the second synchronous pulley 18 respectively. When the filter plate 21 is reset after cleaning, the motor 8 is started to reverse, so that the lead screw 9 drives the first friction wheel 13 to rotate, thereby causing the second friction wheel 15 to drive the rotating rod 14 to rotate. Under the drive of the rotating rod 14, the synchronous belt 19 engages with the first synchronous pulley 16 and the second synchronous pulley 18 respectively, thereby driving the two winding rods 17 to rotate in opposite directions at the same time, releasing the traction rope 20. Under the action of the filter plate 21's own gravity, it goes deep into the liquid storage tank 3 and returns to its original position.

[0038] See Figures 1-4In the above embodiments, the traction rope 20 is made of 310S stainless steel and the surface of the traction rope 20 is coated with a ceramic coating. The traction rope 20 made of 310S stainless steel has better corrosion resistance than ordinary stainless steel and is not easily oxidized and peeled in aluminum-zinc alloy liquid. At the same time, the ceramic coating can form a high-temperature and corrosion-resistant barrier on the surface of the traction rope 20, preventing the metal substrate from directly contacting the lead-zinc liquid, thereby further enhancing the corrosion resistance of the traction rope 20 and extending the service life of the traction rope 20.

[0039] Example 2: To facilitate quick removal of filter plate 21 by staff, Example 2 is an improvement upon Example 1. (See attached document for details.) Figure 3 One end of the traction rope 20 is connected to a hanging rod 23, and the hanging rod 23 is detachably connected to the hanging ear 22. The worker pushes the filter plate 21 so that the hanging ear 22 on one side of the filter plate 21 is detached from the hanging rod 23, and then supports the filter plate 21 so that the hanging ear 22 on the other side is detached from the hanging rod 23, and the filter plate 21 is removed. This way, the worker does not need to remove the four sets of traction ropes 20 separately to remove the filter plate 21, which is simple and quick.

[0040] The implementation principle of this utility model is as follows: The operator turns on two sets of heating mechanisms 4 to make them reach the predetermined temperature. Then, the workpiece to be plated is fixed on the slide 11 by the clamp 12 and the hydraulic cylinder 6 is started. The output end of the hydraulic cylinder 6 drives the fixing frame 7 to move down along the slide groove, which in turn drives the motor 8, the lead screw 9 and the guide rod 10 to move down, so that the slide 11 carries the workpiece to be plated into the preheating tank 2 for preheating. When the workpiece to be plated reaches the predetermined temperature, the hydraulic cylinder 6 is started to lift it back to its original position. At this time, the motor 8 is started to rotate forward. The output end of the motor 8 drives the lead screw 9 to rotate. Guided by the guide rod 10, the slide 11 carries the workpiece to be plated to move above the liquid storage tank 3. The motor 8 is turned off and the hydraulic cylinder 6 is started to immerse the workpiece to be plated in the aluminum-zinc alloy solution to start hot plating. After hot plating is completed, the workpiece to be plated is separated from the aluminum-zinc alloy solution. After cooling, it is taken out and the above steps are repeated for the hot plating operation of the next workpiece to be plated.

[0041] When it is necessary to clean the steel slag inside the aluminum-zinc alloy solution, the operator starts the hydraulic cylinder 6. The output end of the hydraulic cylinder 6 drives the fixed frame 7 to move up to the highest point, so that the first friction wheel 13 contacts the second friction wheel 15. At this time, the hydraulic cylinder 6 is closed and the motor 8 is started. Driven by the output end of the motor 8, the rotating rod 14 drives the two first synchronous wheels 16 to rotate. Through the synchronous belt 19, the two second synchronous wheels 18 drive the winding rod 17 to rotate simultaneously, winding the traction rope 20. The traction rope 20 drives the filter plate 21 to rise and separate from the aluminum-zinc alloy solution. After the filter plate 21 cools down, the traction rope 20 is untied and the filter plate 21 is removed. The steel slag on the filter plate 21 is cleaned and then it is reinstalled.

[0042] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
