Description

Technical Field

[0001] This utility model belongs to the field of hot-dip galvanizing technology, and in particular relates to a hot-dip galvanizing apparatus. Background Technology

[0002] Hot-dip galvanizing, an important technological process, involves immersing metal materials such as steel, stainless steel, and cast iron into molten liquid metal or alloy to obtain a uniform coating on their surface. This coating has immeasurable value in improving the corrosion resistance of metals, extending their service life, and saving energy and materials.

[0003] However, existing hot-dip galvanizing equipment typically uses only a single heated galvanizing bath. This simple structure reveals several problems in actual operation. Particularly during the process of transferring workpieces into and out of the molten zinc, zinc dross inside the bath and zinc oxide on the surface can easily contaminate the workpieces, affecting the quality and effectiveness of the galvanizing process.

[0004] Therefore, it is essential to invent a hot-dip galvanizing device. Utility Model Content

[0005] The purpose of this utility model is to provide a hot-dip galvanizing apparatus to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a hot-dip galvanizing apparatus, comprising a galvanizing tank, a slag removal mechanism, a chute, a slag blowing mechanism, a liquid delivery pipe, and a heating plate. The galvanizing tank is fixed to the ground, and its interior is filled with molten zinc. A slag removal mechanism is fixed inside the galvanizing tank. The actuator of the slag removal mechanism is slidably connected to the chute, which is located on the inner wall of the galvanizing tank. The slag removal mechanism is bolted to one side of the galvanizing tank, and a liquid delivery pipe is fixed to the upper side of the galvanizing tank. Several first nozzles are fixed to the outer side of the liquid delivery pipe via solenoid valves, with the output ends of the first nozzles all facing the galvanizing tank. One end of the liquid delivery pipe is fixed to an external pipeline via a connector, and a heating plate is installed on the lower side of the liquid delivery pipe, which is bolted to the inside of the galvanizing tank.

[0008] Furthermore, the slag removal mechanism includes a rotating column, a motor, a push plate, and a slider. The rotating column is rotatably installed inside the galvanizing tank via a support bearing, and one end of the rotating column is fixed to the output end of the motor. The motor is fixed to the outer side of the galvanizing tank by bolts. The outer side of the rotating column is fixed with a push plate by bolts, and the push plate has several through holes. The two ends of the push plate are respectively fixed with sliders by welding, and the sliders are slidably disposed inside corresponding grooves. This arrangement can prevent the zinc slag inside the zinc bath and the zinc oxide on the surface of the zinc bath from affecting the galvanizing of the workpiece when the workpiece is moved into the galvanizing tank.

[0009] Furthermore, the slag blowing mechanism includes a blower, an air supply pipe, a second nozzle, and a positioning frame. The blower is fixed to the outer side of the galvanizing tank with bolts, and the output end of the blower is fixed to the air supply pipe through a connector. The other end of the air supply pipe is fixed to several second nozzles through a connector. The second nozzles are all fixed to the positioning frame with bolts, and the output ends of the second nozzles all face the inside of the galvanizing tank. This arrangement can prevent the workpiece from coming into contact with zinc oxide when it is removed.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The slag removal mechanism of this utility model can drive the push plate to rotate through the cooperation of the motor and the rotating column before the workpiece is moved into the galvanizing tank by the conveying equipment. The push plate pushes the zinc slag inside the zinc liquid and the zinc oxide on the surface of the zinc liquid to one side of the galvanizing tank, thereby avoiding the zinc slag inside the zinc liquid and the zinc oxide on the surface of the zinc liquid from affecting the galvanizing of the workpiece.

[0012] 2. The slag blowing mechanism of this utility model can draw external gas through a fan before removing the workpiece from the zinc bath after galvanizing. The gas is then transported to the second nozzle through a gas supply pipe and sprayed onto the upper surface of the zinc bath through the second nozzle, thereby blowing the zinc oxide on the upper surface of the zinc bath to one side of the galvanizing tank, so that the workpiece will not come into contact with the zinc oxide when it is removed.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] In the description of this utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] Please see Figure 1 As shown, this utility model is a hot-dip galvanizing device, including a galvanizing tank 1, a slag removal mechanism 2, a chute 3, a slag blowing mechanism 4, a liquid delivery pipe 5, and a heating plate 6. The galvanizing tank 1 is fixed on the ground, and the interior of the galvanizing tank 1 is filled with molten zinc. The slag removal mechanism 2 is fixed inside the galvanizing tank 1. The actuator of the slag removal mechanism 2 is slidably connected to the chute 3, which is located on the inner wall of the galvanizing tank 1. The slag removal mechanism 2 is fixed to one side of the galvanizing tank 1 by bolts, and the liquid delivery pipe 5 is fixed to the upper side of the galvanizing tank 1. Several first nozzles are fixed to the outer side of the liquid delivery pipe 5 by solenoid valves, and the output ends of the first nozzles are all facing the galvanizing tank 1. One end of the liquid delivery pipe 5 is fixed to an external pipeline by a connector, and the heating plate 6 is provided on the lower side of the liquid delivery pipe 5. The heating plate 6 is fixed inside the galvanizing tank 1 by bolts.

[0022] like Figure 2As shown, the slag removal mechanism 2 includes a rotating column 21, a motor 22, a push plate 23, and a slider 24. The rotating column 21 is rotatably installed inside the galvanizing tank 1 via a support bearing, and one end of the rotating column 21 is fixed to the output end of the motor 22. The motor 22 is fixed to the outer side of the galvanizing tank 1 by bolts. The outer side of the rotating column 21 is fixed with a push plate 23 by bolts, and the push plate 23 has several through holes. The two ends of the push plate 23 are respectively fixed with sliders 24 by welding. The sliders 24 are slidably arranged inside the corresponding slide grooves 3. Before the workpiece is moved into the galvanizing tank 1 by the conveying equipment, the push plate 23 can be rotated by the cooperation of the motor 22 and the rotating column 21. The push plate 23 pushes the zinc slag inside the zinc liquid and the zinc oxide on the surface of the zinc liquid to one side of the galvanizing tank 1, thereby avoiding the zinc slag inside the zinc liquid and the zinc oxide on the surface of the zinc liquid from affecting the galvanizing of the workpiece.

[0023] like Figure 3 As shown, the slag blowing mechanism 4 includes a blower 41, an air supply pipe 42, second nozzles 43, and a positioning frame 44. The blower 41 is fixed to the outer side of the galvanizing tank 1 by bolts, and the output end of the blower 41 is fixed to the air supply pipe 42 by a connector. The other end of the air supply pipe 42 is fixed to several second nozzles 43 by a connector. The second nozzles 43 are all fixed to the positioning frame 44 by bolts, and the output ends of the second nozzles 43 all face the inside of the galvanizing tank 1. When the workpiece is galvanized and before it needs to be removed from the zinc liquid, the blower 41 can draw in external gas, and then the gas is transported to the second nozzles 43 through the air supply pipe 42. Then, the second nozzles 43 spray the gas onto the upper surface of the zinc liquid, thereby blowing the zinc oxide on the upper surface of the zinc liquid to one side of the galvanizing tank 1, so that it will not come into contact with the zinc oxide when the workpiece is removed.

[0024] Please see Figure 1-3 As shown, this utility model is a hot-dip galvanizing device. Its working principle is as follows: When in use, zinc liquid is first filled into the galvanizing tank 1, and the temperature of the zinc liquid is maintained by the heating plate 6. Then, the zinc slag inside the zinc liquid and the zinc oxide on the surface of the zinc liquid are pushed to one side of the galvanizing tank 1 by the slag removal mechanism 2. At this time, the workpiece can be moved into the galvanizing tank 1 by the external conveying equipment, so that the zinc liquid submerges the workpiece. After the workpiece is galvanized, the zinc oxide on the surface of the zinc liquid can be moved to one side of the galvanizing tank 1 by the slag blowing mechanism 4. Then, the workpiece is taken out from the galvanizing tank 1 by the external conveying equipment.
