Description

Technical Field

[0001] This utility model relates to the field of steel plate galvanizing technology, specifically to galvanizing equipment for the outer surface treatment of steel plate production. Background Technology

[0002] In today's era, with the booming development of many industries such as construction, the demand for steel plates has reached new heights in both quantity and quality. In particular, the market demand for galvanized steel plates with excellent corrosion resistance has shown explosive growth. The construction industry is increasingly reliant on galvanized steel plates to create more robust, durable, and aesthetically pleasing building structures. Traditional steel plate production surface treatment galvanizing equipment can no longer meet such diverse and high-standard requirements. There is an urgent need for new and efficient galvanizing equipment to innovate production processes and improve product quality. Therefore, steel plate production surface treatment galvanizing equipment has emerged.

[0003] However, existing galvanizing equipment for the external surface treatment of steel plates has the following problems: First, the residual zinc liquid on the surface of the steel plate after galvanizing cannot be quickly and evenly shaken off, which easily leads to uneven zinc layer thickness, local accumulation or flow marks, affecting the appearance and performance of the product. Air bubbles on the steel plate surface are difficult to remove, causing the galvanized layer to easily peel off and crack during subsequent use. In addition, the residual zinc liquid requires a longer drying time, extending the production cycle. Second, the oxide scale, zinc dross, and other impurities continuously generated on the zinc liquid surface will affect production quality and efficiency. These impurities easily adhere to the steel plate surface, causing defects such as pitting and dents in the galvanized layer, reducing the product qualification rate, accelerating the corrosion of the zinc pot's inner wall, and shortening the equipment's service life.

[0004] To address these issues, we offer galvanizing equipment for the external surface treatment of steel plates. Utility Model Content

[0005] The purpose of this invention is to provide a galvanizing equipment for the outer surface treatment of steel plates, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a galvanizing equipment for the outer surface treatment of steel plates, including a zinc pot, wherein a vibration and liquid shaking mechanism is installed on the top surface of the zinc pot, and a slag skimming mechanism is provided on one side of the zinc pot.

[0007] Preferably, the vibration and liquid shaking mechanism includes a bracket fixedly connected to the top surface of the zinc pot. Two sets of hydraulic cylinders are fixedly connected to the top surface of the bracket. The piston rods driven by the hydraulic cylinders pass through the openings provided on the bracket, enabling the connecting parts fixedly connected to the bottom surface to move up and down. When the raw material is galvanized, the piston rods on both sides move synchronously to completely immerse the raw material at the bottom into the zinc pot. After galvanizing is completed, the piston rod on one side moves first to create an angle between the raw material and the zinc liquid plane, and then the piston rods on both sides retract synchronously, lifting the raw material out of the zinc pot.

[0008] Preferably, a rotating seat is hinged below the connector to compensate for the asynchronous operation of the two sets of piston rods. A hook is fixedly connected to the bottom surface of the rotating seat, and a lifting chain is hung on the hook. A structural frame is fixedly connected to the bottom surface of the lifting chain on both sides.

[0009] Preferably, the structural frame has several connecting slots fixedly connected to both sides. A load-bearing frame is fixedly connected to the connecting slots by threads. The position of the load-bearing frame on the structural frame can be adjusted through the connecting slots to accommodate steel plate raw materials of any type and length that are hoisted below. Raw material fixing chains are fixedly connected to the several slots of the load-bearing frame. After the raw material is fixed with wire in sequence, both ends are hung in the raw material fixing chain rings on both sides. A vibration motor is fixedly connected to the top surface of the structural frame to shake the raw material fixed on the raw material fixing chain.

[0010] Preferably, the skimming mechanism includes an electric heating plate installed on the outer edge of the zinc pot to heat the molten zinc, and two sets of hydraulic telescopic rods fixedly connected to one side of the zinc pot. The hydraulic telescopic rods drive a skimming plate fixedly connected to one end to remove the surface oxide scale from the molten zinc in the zinc pot and accelerate the heat mixing of the liquid.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model incorporates a hydraulic cylinder and a vibrating motor to form a vibrating liquid-shaking mechanism. During galvanizing, two sets of hydraulic cylinders synchronously drive the piston rods downward to completely immerse the raw material in the zinc bath. After galvanizing, one side of the piston rod retracts upward first, tilting the raw material at a certain angle. Gravity and the tilted surface promote the rapid sliding of excess zinc bath. Subsequently, both sides of the piston rod retract synchronously, smoothly lifting the raw material out of the zinc pot, ensuring the uniformity of the galvanized layer. After the steel plate is galvanized and lifted out of the zinc pot, the vibrating motor on the top surface of the structure is activated. Vibration causes excess zinc bath on the surface of the steel plate to be shaken off quickly and evenly, ensuring the quality of the galvanized layer and achieving efficient and refined production of the galvanizing process. 2. This utility model incorporates a slag skimming mechanism by adding hydraulic telescopic rods and slag removal plates. Two sets of hydraulic telescopic rods on one side of the zinc pot drive the slag removal plates to reciprocate on the surface of the zinc liquid through telescopic movements, promptly scraping away and cleaning impurities such as oxide scale from the zinc liquid surface. At the same time, it can promote the flow of zinc liquid, accelerate the mixing of heat inside the zinc liquid, improve the smoothness and gloss of the galvanized layer, increase the product qualification rate, and also ensure good fluidity and heat conduction efficiency of zinc liquid, reducing energy consumption.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 One embodiment of this utility model is a galvanizing equipment for the outer surface treatment of steel plates, including a zinc pot 1, a vibration and liquid shaking mechanism 2 installed on the top surface of the zinc pot 1, and a slag skimming mechanism 3 provided on one side of the zinc pot 1.

[0024] Furthermore, the vibration and liquid shaking mechanism 2 includes a bracket 201 fixedly connected to the top surface of the zinc pot 1. Two sets of hydraulic cylinders 202 are fixedly connected to the top surface of the bracket 201. The piston rods 203 driven by the hydraulic cylinders 202 pass through the openings provided on the bracket 201, enabling the connecting piece 204 fixedly connected to the bottom surface to move up and down. When the raw material is galvanized, the piston rods 203 on both sides move synchronously to completely immerse the raw material at the bottom into the zinc pot 1. After galvanizing, the piston rod 203 on one side moves first to create an angle between the raw material and the zinc liquid plane, and then the piston rods 203 on both sides retract synchronously, lifting the raw material out of the zinc pot 1. During galvanizing, the two sets of hydraulic cylinders 202 synchronously drive the piston rods 203 to move downward, completely immersing the raw material in the zinc liquid. After galvanizing, the piston rod 203 on one side retracts upward first, tilting the raw material at a certain angle, using gravity and the tilted surface to promote the rapid sliding of excess zinc liquid. Then the piston rods 203 on both sides retract synchronously, smoothly lifting the raw material out of the zinc pot 1, ensuring the uniformity of the galvanized layer.

[0025] Furthermore, a rotating seat 205 is hinged below the connector 204 to compensate for the asynchronous movement of the two sets of piston rods 203. A hook 206 is fixedly connected to the bottom surface of the rotating seat 205, and a lifting chain 207 is hung on the hook 206. A structural frame 208 is fixedly connected to the bottom surface of the lifting chain 207 on both sides. The two sets of piston rods 203 are hinged to the rotating seat 205 through the connector 204. When the piston rods 203 move asynchronously, the rotating seat 205 can rotate flexibly around the hinge point to compensate for the difference in movement of the piston rods 203 on both sides. The hook 206 below the rotating seat 205 hangs the lifting chain 207, which transmits the kinetic force of the piston rods 203 to the bottom structural frame 208. The lifting chains 207 on both sides work together to ensure the stable lifting and lowering of the structural frame 208.

[0026] Furthermore, several connecting slots 209 are fixedly connected to both sides of the structural frame 208. A load rack 210 is fixedly connected to each connecting slot 209 via threads. The position of the load rack 210 on the structural frame 208 can be adjusted via the connecting slots 209 to accommodate steel plate raw materials of any size and length hoisted below. Raw material fixing chains 211 are fixedly connected to the slots of the load rack 210. After the raw material is fixed with wire in sequence, both ends are hung in the rings of the raw material fixing chains 211 on both sides. A vibration motor 212 is fixedly connected to the top surface of the structural frame 208. The raw materials fixed on the raw material fixing chain 211 are shaken to remove excess zinc. The connecting grooves 209 on both sides of the structural frame 208 can be used to flexibly adjust the position of the load rack 210 through threaded connection to adapt to steel plate raw materials of different models and lengths, ensuring hoisting stability. After the operator fixes the steel plate raw material with iron wire, the two ends of the iron wire are hung in the ring of the raw material fixing chain 211 to complete the raw material fixing. After the steel plate is galvanized and lifted out of the zinc pot 1, the vibration motor 212 on the top surface of the structural frame 208 is started. The vibration causes the excess zinc liquid on the surface of the steel plate to be shaken off quickly and evenly, ensuring the quality of the galvanized layer.

[0027] Furthermore, the slag skimming mechanism 3 includes an electric heating plate 301 installed on the outer edge of the zinc pot 1 to heat the zinc liquid. Two sets of hydraulic telescopic rods 302 are fixedly connected to one side of the zinc pot 1. The hydraulic telescopic rods 302 drive a slag removal plate 303 fixedly connected to one end to remove the surface oxide scale of the zinc liquid in the zinc pot 1 and accelerate the heat mixing of the liquid. The two sets of hydraulic telescopic rods 302 on one side of the zinc pot 1 drive the slag removal plate 303 to reciprocate on the surface of the zinc liquid through telescopic movement, so as to scrape off and clean the oxide scale and other impurities on the surface of the zinc liquid in time. At the same time, it can drive the zinc liquid to flow, accelerate the heat mixing inside the zinc liquid, and make the temperature distribution of the zinc liquid more uniform.

[0028] Working principle: During galvanizing, two sets of hydraulic cylinders 202 synchronously drive the piston rods 203 to move downwards, completely immersing the raw material in the zinc bath. After galvanizing, one piston rod 203 first retracts upwards, tilting the raw material at a certain angle. Gravity and the tilted surface promote the rapid sliding of excess zinc. Subsequently, both piston rods 203 retract synchronously, smoothly lifting the raw material out of the zinc pot 1, ensuring the uniformity of the galvanized layer. The two sets of piston rods 203 are hinged to the rotating seat 205 via a connector 204. When the piston rods 203 move asynchronously, the rotating seat 205 can rotate flexibly around the hinge point to compensate for the movement of the piston rods 203 on both sides. Due to the differences, after the operator fixes the steel plate raw material with iron wire, the two ends of the iron wire are hung in the ring of the raw material fixing chain 211 to complete the raw material fixing. After the steel plate is galvanized and lifted out of the zinc pot 1, the vibration motor 212 on the top surface of the structural frame 208 is started. The vibration causes the excess zinc liquid on the surface of the steel plate to be shaken off quickly and evenly, ensuring the quality of the galvanized layer. The two sets of hydraulic telescopic rods 302 on one side of the zinc pot 1 drive the slag removal plate 303 to move back and forth on the surface of the zinc liquid through telescopic action, so as to scrape off the oxide scale and other impurities on the surface of the zinc liquid in time. At the same time, it can drive the zinc liquid to flow, accelerate the mixing of heat inside the zinc liquid, and make the temperature distribution of the zinc liquid more uniform.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
