Description

Technical Field

[0001] The invention belongs to the technical field of galvanizing production, and in particular relates to a hot-dip galvanizing tank structure for hot-dip galvanizing production and processing. Background Art

[0002] Hot-dip galvanizing is to make molten metal react with iron matrix to produce alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel parts first. In order to remove the iron oxide on the surface of the steel parts, after pickling, they are cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent to the hot-dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

[0003] In the process of using the existing hot-dip galvanizing tank structure for metal product processing, the metal product is placed in the galvanizing tank through external lifting equipment for hot-dip galvanizing treatment. During the treatment process, the gas generated by the high temperature of the galvanizing solution itself and the gas generated after the metal parts come into contact with the galvanizing solution are easily emitted around the device, causing harm to the environment and workers. In order to solve this technical problem, Chinese utility model patent CN218507882U discloses a hot-dip galvanizing tank structure for metal product processing, including a box body, a heating pipe and a support frame, wherein reinforcing ribs are installed on both sides of the box body, a liquid inlet pipe is connected to one side of the bottom of the box body, and another liquid inlet pipe is connected to the bottom of the box body. One side is connected with a drain pipe, the bottom end of the box body is fixed with the heating pipe, a temperature sensing probe is arranged on one side above the heating pipe, and supporting plates are fixed on both sides of the lower middle part of the box body. By arranging a support frame, a collecting tank and a connecting port, the collecting tank can be fixed on both sides of the top of the box body through the support frame, and then the collecting tank is connected to the external exhaust device through the connecting port. During use, the gas generated by the high temperature of the galvanizing solution itself and the gas generated after the metal parts come into contact with the galvanizing solution can be collected through the collecting tank, so as to avoid the overflow of these gases and cause harm to the environment and workers, thereby improving the environmental protection of the device and the rationality of the hot-dip galvanizing tank structure.

[0004] Although the above-mentioned prior art can extract harmful gases to the outside when the workpiece is galvanized, during the galvanizing process, the zinc liquid will tumble due to the heating and the heat generated when the steel workpiece enters the zinc liquid. This tumbling helps the zinc liquid on the surface of the steel workpiece to solidify quickly to form a solid shell, thereby promoting the formation of an iron-zinc alloy layer. The tumbling zinc liquid can ensure that the surface of the steel workpiece is evenly covered with a layer of zinc, thereby improving the corrosion resistance. The zinc liquid is prone to sputtering outward when tumbling, resulting in waste of zinc liquid and pollution of the working environment. The tumbling zinc liquid will enter the interior of the collecting tanks on both sides, which is likely to cause damage to the exhaust device and reduce the service life of the exhaust device. Summary of the invention

The tumbling zinc liquid can ensure that the surface of the steel parts is evenly covered with a layer of zinc, thereby improving the corrosion resistance. The zinc liquid is prone to sputtering outward when tumbling, resulting in waste of zinc liquid and pollution of the working environment, and the tumbling zinc liquid will enter the interior of the collecting tanks on both sides, easily causing damage to the exhaust device and reducing the service life of the exhaust device.

DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.
