Description

Technical Field

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

[0002] In simple terms, the principle of hot-dip galvanizing is to immerse cleaned iron parts in a zinc bath through the wetting action of a flux, allowing the steel to react with molten zinc to form an alloyed film. A good hot-dip galvanizing operation should ensure that each process is strictly controlled to fully realize its function. If the operation of the previous process is not done well, it will cause a chain reaction of adverse reactions in the subsequent processes, which will greatly increase the operating costs or produce defective hot-dip galvanized products.

[0003] Existing technologies, such as CN217517007U, describe a waste heat recovery and utilization device for hot-dip galvanizing of steel pipes. This device solves the problems of inconvenient angle adjustment, time-consuming and labor-intensive assembly, and difficulty in movement of current hot-dip galvanizing of steel pipes waste heat recovery and utilization devices, which require manual or tool-assisted handling. It includes a main body for heat recovery and utilization, with a fixed mounting box on the outside. An angle adjustment control motor is installed inside the fixed mounting box. A movable support column is installed at the output end of the control motor. A guide rod is fixed inside the support column. A shock-absorbing tube is movably connected to one end of the guide rod, and a shock-absorbing spring is installed at the top of the shock-absorbing tube. This invention offers advantages such as convenient angle adjustment after main body installation, no direct operation by personnel required, time and labor saving, convenient assembly, easy movement, high safety during movement, and good seismic resistance.

[0004] Because existing hot-dip galvanizing pots for steel pipes require a uniform distribution of various components (such as aluminum and zinc) in the zinc bath during the hot-dip galvanizing process to ensure the stability of the galvanized layer quality, some devices do not agitate the components. As the galvanizing process progresses, the composition of the zinc bath surface changes due to oxidation from contact with air, and the composition of the zinc bath at the bottom may also differ from that at the top due to reactions with the steel pipe, resulting in stratification of the zinc bath composition. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that during the hot-dip galvanizing process, various components (such as aluminum and zinc) in the zinc bath need to be uniformly distributed to ensure the stability of the galvanized layer. Some devices do not stir the components, and as the galvanizing process proceeds, the components on the surface of the zinc bath will change due to oxidation from contact with air, and the components at the bottom of the zinc bath may also differ from those at the top due to reactions with the steel pipe, resulting in stratification of the zinc bath components. Therefore, this invention proposes a hot-dip galvanizing pot for steel pipes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a hot-dip galvanizing pot for steel pipes, comprising a main body and a rectangular trough, wherein the rectangular trough is formed at the top of the main body, and mounting frames are fixedly connected to both sides of the main body.

[0009] Furthermore, a movable rod is threadedly connected to the surface of the lead screw, a second motor is provided on one side of the lead screw, a fan is provided at the bottom of the upper end of the movable rod, and a movable slot is provided on one side of the rectangular groove.

[0010] Furthermore, a movable plate is movably connected inside the movable groove, a positioning hole is provided on one side of the movable plate, and a fixed plate is fixedly connected to one side of the rectangular groove.

[0011] Furthermore, a positioning rod is movably connected to the surface of the fixed plate, the positioning rod is movably connected to the inside of the positioning hole, and a limit frame is fixedly connected to one side of the fixed plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a stirring device, the output end of the first motor can drive the stirring shaft to rotate. At the same time as the shaft rotates, the connecting block and the mounting block will also rotate. Through the action of centrifugal force, the sliding rod will slide inside the sliding groove, thereby increasing the stirring area of ​​the material. While rotating, the stirring blades will further stir the material. The stirring device can make the zinc liquid circulate in the pot, enhance heat transfer, and allow the heat generated by the heating source at the bottom of the pot to be quickly and evenly transferred to the entire zinc liquid, effectively avoiding local overheating or undercooling of the zinc liquid.

[0015] 2. In this utility model, a cooling device is installed, which uses the output end of a second motor to drive a lead screw. During operation, the screw's moving rod slides left and right, driving a fan to cool the surface and interior of the equipment. Simultaneously, a movable plate can move within the movable slot to adjust the ventilation according to the equipment's cooling requirements. When adjusted to a suitable position, the positioning rod is fixed inside the positioning hole. A spring inside the limiting frame drives a limiting block to fix or loosen the positioning rod. The cooling device can reduce the ambient temperature around the galvanizing pot, reduce the thermal stress and thermal fatigue of the pot material caused by high temperatures, delay the aging and deformation of the pot material, extend the service life of the galvanizing pot, and reduce the maintenance and replacement costs of the equipment.
