Description

Technical Field

[0001] This utility model relates to the field of hot-dip galvanizing zinc pot technology, specifically to an automatic temperature control guide channel device for hot-dip galvanizing zinc pots. Background Technology

[0002] Hot-dip galvanizing is one of the most important anti-corrosion methods for steel materials, and the working condition of its core equipment, the zinc pot, directly determines the coating quality and production cost.

[0003] Due to the limited natural convection effect of molten zinc, thermal stratification easily occurs within the pot, meaning the bottom temperature is lower and the top temperature is higher. This temperature difference leads to uneven galvanized layer thickness, affecting the quality stability of galvanized products and reducing the product yield. Therefore, an automatic temperature-controlled flow channel device for hot-dip galvanizing pots is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic temperature control and diversion channel device for hot-dip galvanizing zinc pots, which has advantages such as significantly improved temperature uniformity and solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic temperature control and diversion channel device for a hot-dip galvanized zinc pot includes a pot body and a channel fixedly connected to the left side of the pot body. The bottom of the pot body is provided with a stirring component for stirring.

[0007] The stirring assembly includes four support rods fixedly connected to the bottom of the pot body. A base plate is fixedly connected between the bottom ends of the four support rods. A controller is fixedly connected to the top of the base plate. The output end of the controller is electrically connected to a variable frequency power supply. The output end of the variable frequency power supply is electrically connected to an electromagnetic coil.

[0008] Furthermore, a lid is provided on the top of the pot body, and a drain valve is fixedly connected to the front of the pot body.

[0009] Furthermore, the four support rods are respectively arranged at the four corners of the bottom of the pot body, and the electromagnetic coil is fixedly connected to the bottom of the pot body.

[0010] Furthermore, a connection port and a return port are provided on the left side of the inner side of the pot body. The inlet end of the tank is fixedly connected to the connection port, and the outlet end of the tank is fixedly connected to the return port.

[0011] Furthermore, a perforated flow equalization plate is fixedly connected to both the inlet and outlet ends of the tank, and several flow guide fins are fixedly connected to the inner sidewall of the tank.

[0012] Furthermore, three heaters are fixedly connected to the front of the tank, and the three heaters are arranged equidistantly along the vertical direction of the tank.

[0013] Furthermore, a housing is fixedly connected to each of the four corners of the top of the base plate, and an electric cylinder is fixedly connected to the inner top wall of the housing. A transport wheel is fixedly connected to one end of the piston rod of the electric cylinder.

[0015] Compared with the prior art, this utility model provides an automatic temperature control and diversion channel device for hot-dip galvanizing zinc pots, which has the following beneficial effects:

[0016] This automatic temperature-controlled flow channel device for hot-dip galvanizing zinc pot combines electromagnetic stirring with a directional circulation flow driven by thermosiphon effect to create a strong circulating flow field inside the pot. The Lorentz force generated by electromagnetic stirring drives the zinc liquid to form a circulating flow covering the entire area inside the pot, while the thermosiphon effect drives the zinc liquid to form a directional circulation between the pot body and the flow channel. This dual circulation mechanism completely breaks the thermal stratification caused by insufficient natural convection of the zinc liquid, making the temperature of the zinc liquid uniform throughout the pot.

[0021] 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.

[0022] Please see Figures 1 to 3The automatic temperature control and diversion channel device for hot-dip galvanizing zinc pot in this embodiment includes a pot body 1 and a channel 2 fixedly connected to the left side of the pot body 1. The bottom of the pot body 1 is provided with a stirring component for stirring.

[0023] Please see Figure 1 In this embodiment, the stirring assembly includes four support rods 3 fixedly connected to the bottom of the pot body 1. A base plate 4 is fixedly connected between the bottom ends of the four support rods 3. A controller 5 is fixedly connected to the top of the base plate 4. The output end of the controller 5 is electrically connected to a frequency converter 6. The output end of the frequency converter 6 is electrically connected to an electromagnetic coil 7.

[0024] Specifically, a lid 8 is provided on the top of the pot body 1, and a drain valve 9 is fixedly connected to the front of the pot body 1.

[0025] Specifically, four support rods 3 are respectively arranged at the four corners of the bottom of the pot body 1, and the electromagnetic coil 7 is fixedly connected to the bottom of the pot body 1.

[0026] It should be noted that fixing the electromagnetic coil 7 to the bottom of the pot body 1 is the most effective and standard installation method for electromagnetic stirring. This arrangement is beneficial for using the magnetic field to drive the denser and cooler zinc liquid to move upward from the bottom of the pot, most effectively breaking up thermal stratification and preventing zinc dross from depositing at the bottom.

[0027] Specifically, a connection port and a return port are provided on the left side of the inner side of the pot body 1, the inlet end of the tank body 2 is fixedly connected to the connection port, and the outlet end of the tank body 2 is fixedly connected to the return port.

[0028] It should be noted that the tank 2 forms a closed circulation loop with the pot body 1 through the connection port and the return port. The connection port is located on the lower left side of the inner side of the pot body 1, and is used to draw the lower-temperature zinc liquid, which may contain slag, into the guide channel; the return port is located on the upper left side, and is used to spray the heated and homogenized zinc liquid back into the pot body 1. This design creates a powerful directional circulation flow, driven by the thermosiphon effect generated by the heater 12 heating the zinc liquid inside the tank 2, supplemented by the synergistic effect of electromagnetic stirring, achieving efficient forced circulation of the zinc liquid.

[0029] Specifically, a perforated flow equalization plate 10 is fixedly connected to both the inlet and outlet ends of the tank 2, and several flow guide fins 11 are fixedly connected to the inner sidewall of the tank 2.

[0030] It should be noted that the porous flow equalizer 10 at the inlet end can filter out large pieces of zinc dross, preventing them from entering the tank 2 and causing blockages, while also ensuring a smooth and uniform flow of molten zinc, reducing turbulence. The porous flow equalizer 10 at the outlet end makes the sprayed molten zinc stream more uniform and gentle, avoiding scouring of the plated workpieces. The guide fins 11 are welded to the inner wall of the tank 2; their main function is to disrupt the boundary layer of the molten zinc flow, enhance turbulence, improve heat exchange efficiency, and ensure that the molten zinc is fully and uniformly heated as it flows through the tank 2.

[0031] Specifically, three heaters 12 are fixedly connected to the front of the tank 2, and the three heaters 12 are arranged equidistantly along the vertical direction of the tank 2.

[0032] It should be noted that the three heaters 12 are arranged at equal intervals along the vertical direction of the tank 2, which realizes segmented and gradient heating of the zinc liquid in the tank 2. This layout avoids local overheating and allows the zinc liquid to be gradually and evenly heated to the set temperature during the flow process, resulting in extremely high thermal efficiency.

[0033] Specifically, housings 13 are fixedly connected to the four corners of the top of the base plate 4, electric cylinders 14 are fixedly connected to the inner top wall of housings 13, and a transport wheel 15 is fixedly connected to one end of the piston rod of electric cylinder 14.

[0034] It should be noted that this structure constitutes a liftable mobile device. When the zinc pot needs to be moved, the controller 5 activates the electric cylinder 14, whose piston rod extends downward, pushing the transport wheel 15 through the wheel opening to contact the ground, lifting the entire device and raising the support leg 16 off the ground, allowing for easy movement.

[0035] Specifically, the inner side of the base plate 4 has four wheel openings, and the wheel openings are connected to the corresponding housing 13. The four corners of the bottom of the base plate 4 are respectively fixedly connected to the support legs 16.

[0036] The working principle of the above embodiments is as follows:

[0037] Driven by the thermosiphon effect, the low-temperature zinc liquid at the bottom of the pot 1 enters the inlet of the tank 2 through the connection port. First, it passes through the porous flow equalization plate 10, where it is evenly flowed and large particles of impurities are filtered out. As the zinc liquid flows through the tank 2, it is gradually and evenly heated to the target temperature by the heaters 12 arranged along the flow path. The guide fins 11 enhance the heat transfer process and prevent local overheating. After being evenly flowed through the porous flow equalization plate 10 from the outlet end, the heated zinc liquid is sprayed back to the upper part of the pot 1 from the return port at a certain speed, forming a directional jet.

[0038] Simultaneously, the variable frequency power supply 6 outputs low-frequency three-phase alternating current with a specific frequency and current to the electromagnetic coil 7. The electromagnetic coil 7 generates a uniformly moving traveling wave magnetic field at the bottom of the pot body 1. This magnetic field induces eddy currents in the conductive zinc liquid. These eddy currents interact with the magnetic field to generate Lorentz force. The Lorentz force pushes the zinc liquid to form a circulating flow field covering the entire area inside the pot body 1. The circulating flow completely breaks the thermal stratification caused by insufficient natural convection of the zinc liquid, making the temperature of the zinc liquid in the entire pot body 1 uniform.

[0039] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
