Description

Technical Field

[0001] The utility model relates to the technical field of galvanized color plate processing, in particular to a galvanizing device used for galvanized color plate processing. Background Art

[0002] Galvanizing refers to a surface treatment technology that coats a layer of zinc on the surface of metals, alloys or other materials for aesthetic purposes and rust prevention. The main method used is hot-dip galvanizing, which is developed from the older hot-dip method. Since France applied hot-dip galvanizing to industry in 1836, it has a history of 170 years. However, the hot-dip galvanizing industry has been developed on a large scale in the past 30 years along with the rapid development of cold-rolled strip steel. The production process of hot-dip galvanized sheet mainly includes: original sheet preparation → pre-plating treatment → hot-dip galvanizing → post-plating treatment → finished product inspection, etc.

[0003] Before galvanizing steel, it needs to undergo pre-plating treatment to remove the original rust or stains on the surface. At present, most of them are immersed in acid solution to make the rust react and fall off the steel plate, and then the steel plate is lifted out of the liquid and placed into the zinc liquid for galvanizing. This will cause the acid liquid to adhere to the surface of the steel plate, affecting the purity and adhesion effect of the zinc liquid.

[0004] For example, a galvanizing device for steel plates disclosed in Chinese patent CN209243148U is connected to a bracket through a hook and a steel rope. The horizontal moving mechanism on the bracket drives the steel plate to move. First, it passes through an acid pool. Under the action of a first hydraulic cylinder and a winding mechanism, the steel plate is immersed in the acid pool for pre-plating treatment. The first hydraulic cylinder is used to reduce the length of the steel rope between the horizontal moving mechanism and the hook to reduce the shaking of the steel plate under the action of inertia. The steel plate passing through the acid pool is pulled out of the liquid surface and placed on a filter. The air pump of the blowing device blows wind from the fan to the steel plate. During this period, the rotating mechanism can drive the steel plate to rotate, so that the acid liquid remaining on the steel plate will be cleaned to prevent it from entering the zinc liquid pool to cause zinc liquid pollution and affect the galvanizing quality.

[0005] However, after the galvanizing device galvanizes the plate, the zinc liquid on the outer side of the plate cannot be dried quickly, which affects the efficiency of the galvanizing work.

[0006] For this reason, we urgently need to provide a galvanizing device with a drying structure for galvanized color plate processing. Utility Model Content

[0010] A further improvement is that a horizontal slide groove is provided at the inner upper end of the support frame, and the outer side of the lower end of the transmission member is slidably connected to the inner side of the slide groove, thereby limiting the movement of the transmission member.

[0011] A further improvement is that the interior of the galvanizing pool is filled with acid solution on the right side of the partition, the interior of the galvanizing pool is filled with zinc solution on the left side of the partition, the front end outer side of the discharge pipe is provided with an external thread, the inner side of the cover is provided with an internal thread, the front end outer side of the discharge pipe is connected with the inner side thread of the cover, so that the cover can be removed from the front end of the discharge pipe by rotating it.

[0012] A further improvement is that the blowing direction of the cold air fan and the hot air fan is forward and downward, so that after the plate is fully immersed in the acid liquid, the telescopic part is started to pull up the placement plate to the bottom of the front end of the cold air fan, and the cold air fan can be started to blow air to the outside of the plate above the placement plate to blow excess acid back into the galvanizing pool.

[0016] In summary, the present application discloses a galvanizing device for processing galvanized color plates.

[0017] According to the technical solution, after the galvanizing of the plate is completed, the telescopic member is started to drive the placement plate and the plate on its upper end to move to the lower front end of the hot air blower, and the hot air blower is turned on to blow hot air to the plate, so that the zinc liquid on the outside of the plate is quickly dried, thereby improving the galvanizing efficiency of the plate.
