Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hot-dip galvanizing technology, specifically relating to a hot-dip galvanizing cooling water circulation device. Background Technology
[0002] Hot-dip galvanizing, also known as hot-dip zinc plating, is a metal surface treatment process in which rust-removed steel parts are immersed in molten zinc, causing a zinc layer to adhere to the surface of the steel parts, thereby achieving the purpose of corrosion prevention. Through this process, a relatively thick zinc-iron alloy layer and a pure zinc layer are formed on the surface of steel products, which can effectively isolate the steel from contact with the external environment and prevent the steel from rusting and corrosion. It is widely used in construction, equipment manufacturing, power and other fields. During the hot-dip galvanizing process, after the steel products are taken out of the high-temperature zinc liquid, the high-temperature zinc layer attached to the surface needs to be cooled and solidified rapidly. If it is not cooled in time, the zinc layer may produce problems such as uneven zinc layer structure, increased zinc ash and zinc dross, and deformation during the slow cooling process. This will not only reduce the mechanical properties and corrosion resistance of the zinc layer, but also waste zinc resources and affect the appearance quality of the zinc layer. Therefore, it is urgent to use a cooling device to cool the steel products after hot-dip galvanizing.
[0003] However, existing cooling devices have a relatively simple structure and lack a structure to promote the circulation of cooling water. They cannot use the circulating cooling water to quickly remove the heat from the surface of steel products, resulting in a slow cooling speed and thus reducing the solidification speed of the zinc layer. Moreover, the lack of a cooling water circulation device means that the water consumption is large, which will waste water resources, increase production costs, and result in poor cooling quality and environmental performance. Therefore, we propose a hot-dip galvanizing cooling water circulation device. Summary of the Invention
[0004] In view of the shortcomings of the above-mentioned background technology, the purpose of this utility model is to provide a hot-dip galvanizing cooling water circulation device. This novel hot-dip galvanizing cooling water circulation device has a structure that promotes the circulation of cooling water. It can use the circulating cooling water to quickly remove the heat from the surface of steel products, effectively improve the cooling and zinc layer solidification speed, prevent the uneven zinc layer structure and deformation caused by slow cooling of steel products, and avoid water waste and reduce production costs, thereby effectively improving the cooling quality and environmental performance.
[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: A hot-dip galvanizing cooling water circulation device includes a zinc liquid storage tank, a water pumping assembly, a return water pipe and a water inlet pipe. The lower end of the zinc liquid storage tank is provided with a water pumping assembly, which includes a first water pumping pipe, a second water pumping pipe and a filter cartridge. The inlet end of the first water pumping pipe is connected to the bottom of the zinc liquid storage tank. A circulation pump is installed on one side of the zinc liquid storage tank through a mounting plate. The outlet of the No. 2 pumping pipe is connected to the inlet of the circulating pump. A filter cartridge is installed between the No. 2 pumping pipe and the No. 1 pumping pipe. An inlet pipe is installed on one side of the top of the zinc liquid storage tank by clamps and screws. A return pipe is installed between the inlet pipe and the circulating pump.
[0006] By adopting the above technical solution, this novel hot-dip galvanizing cooling water circulation device has a structure that promotes the circulation of cooling water. The circulating cooling water can quickly remove the heat from the surface of steel products, effectively increasing the cooling and zinc layer solidification speed. It prevents uneven zinc layer structure and deformation caused by slow cooling of steel products, and avoids water waste and reduces production costs, thereby effectively improving the cooling quality and environmental performance.

[0008] By adopting the above technical solution, personnel can connect the No. 2 pumping pipe to the filter cartridge using screws and other connectors through the No. 1 flange and the No. 2 flange, and connect the No. 1 pumping pipe to the filter cartridge through the No. 3 flange and the No. 4 flange.
[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the pumping assembly also includes a drain valve, which is located on the first pumping pipe.
[0010] Based on the above scheme and as a preferred option: the bottom of the zinc liquid storage tank is provided with insertion slots on all four sides, and the lower end of the zinc liquid storage tank is provided with a mounting bracket.
[0011] By adopting the above technical solution, personnel place the zinc liquid storage tank inside the mounting frame, and the plug can be inserted into the plug slot, thereby using the mounting frame to support the zinc liquid storage tank.
[0012] Based on the above scheme and as the preferred option, brackets are installed around both the No. 2 pumping pipe and the return pipe.
[0013] The outstanding and beneficial technical effects of this utility model compared to the prior art are: The hot-dip galvanizing cooling water circulation device of this invention allows the zinc liquid to flow back to the inside of the zinc liquid storage tank through a circulation pump, a No. 1 water pumping pipe, and a No. 2 water pumping pipe, thus achieving recycling. The filter cartridge can filter the extracted zinc liquid through physical interception and adsorption, which helps to improve the purity of the zinc liquid.

To utilize circulating cooling water to quickly remove heat from the surface of steel products, thereby improving cooling quality and environmental performance, such as... Figure 1-5 As shown.
