Description

Technical Field

[0001] The utility model relates to the field of hot-dip galvanized plate processing, in particular to a hot-dip galvanized plate and a hot-dip galvanized plate processing device. Background Art

[0002] Hot-dip galvanized sheet is hot-rolled galvanized sheet. Hot-rolled galvanized sheet is formed by direct galvanizing after pickling with hot plate as the substrate. With the development of hot rolling process technology, the quality of hot-rolled products has been continuously improved, and the thickness has gradually decreased. The use of hot-rolled thin plates as raw materials to produce hot-rolled galvanized sheets has replaced the original traditional single-sheet galvanizing, broadening the scope of use of hot-rolled galvanized sheets. In the production process of hot-rolled galvanized sheets, the hot-dip galvanized sheet substrate needs to be heated in a heating furnace and then sent to the hot rolling equipment for rolling and forming. During the smelting, hot rolling, heat treatment and other processes, a layer of oxide scale will be generated on the surface of the substrate. In order to obtain the smoothness, brightness and service life of the stainless steel surface, it must be pickled to remove the oxide scale before the next processing step. The hot-dip galvanizing process can only be carried out after the surface of the material is peeled to ensure that it is smooth and free of impurities. In the process of transporting and processing the hot-dip galvanized sheet substrate, it is inevitable that paint and other objects will stick to it. Therefore, the hot-dip galvanized sheet substrate needs to be degreased before pickling. In the prior art, when processing the hot-dip galvanized sheet substrate, degreasing and pickling are generally carried out directly. When the hot-dip galvanized sheet substrate is stained with a lot of paint and other debris, due to the uneven thickness of the paint and other debris on the substrate, if it is directly degreased, the thicker paint position will be processed more slowly. In order to completely clean the substrate, it is necessary to wait until the thicker paint position is completely cleaned. This results in a low processing efficiency if degreasing and pickling are directly carried out without prior cleaning. Therefore, it is necessary to propose a hot-dip galvanized sheet and a hot-dip galvanized sheet processing device to solve the above problems. Utility Model Content

This can ensure the effect of dust absorption, and then can continuously clean the galvanized substrate, improve processing efficiency, and protect the working environment, which is conducive to continuous production.

The wavy patterns on the surface of the galvanized substrate 12 can increase the adhesion of the galvanized layer, making the adhesion between the galvanized layer and the galvanized substrate more firm, thereby improving the quality of the galvanized sheet.

[0024] The utility model also provides a hot-dip galvanized sheet processing device, comprising a processing tank 1, wherein two partition plates 5 are arranged in the processing tank 1, and the two partition plates 5 divide the processing tank 1 into three tanks, which are a pretreatment tank 101, a degreasing tank 102 and a pickling tank 103 in sequence. The pretreatment tank 101, the degreasing tank 102 and the pickling tank 103 are all provided with pneumatic pressure rollers 2, and the pneumatic pressure rollers 2 are commonly used pressure rollers on the market, and are used to drive the galvanized substrate 12 to move in the processing tank 1. Other methods of conveying the galvanized substrate 12 can also be used, which is not limited here and therefore will not be described in detail.

[0025] A feed port is provided at one end of the processing tank 1 , and one end of the galvanized substrate 12 moves through the feed port and extends into the interior of the processing tank 1 .

[0026] In order to solve the problem that when the hot-dip galvanized sheet substrate is stained with a lot of paint and other debris, due to the uneven thickness of the paint and other debris on the substrate, if the degreasing treatment is directly carried out, the position with thicker paint will be processed slowly, and in order to completely clean the substrate, it is necessary to wait until the position with thicker paint is completely cleaned. This leads to the problem that if the degreasing and pickling treatment are directly carried out without prior cleaning, the treatment efficiency will be low. The utility model provides a mounting plate 3 on one side of the treatment tank 1, and a motor 4 is provided on the mounting plate 3. A disc 6 is fixedly installed on one end of the output shaft of the motor 4, and a connecting plate 7 is rotatably installed on the disc 6. A U-shaped mounting seat 9 is slidably installed in the pretreatment tank 101, and a pull rod 8 is fixedly installed on the U-shaped mounting seat 9. The pull rod 8 is rotatably connected to the connecting plate 7. Springs 10 are fixedly installed on the upper and lower inner walls of the U-shaped mounting seat 9, and the U-shaped mounting seat 9 is also provided with a There are two steel brushes 11, which are arranged up and down, and the sides of the two steel brushes 11 that are away from each other are fixedly connected to the corresponding springs 10. When working, the galvanized substrate 12 extends into the processing tank 1, and is processed through the pretreatment tank 101, the degreasing tank 102 and the pickling tank 103 in turn, and passes through three pneumatic rollers 2 in turn. At this time, the galvanized substrate 12 is in the middle of the U-shaped mounting seat 9 and between the two steel brushes 11. At this time, the motor 4 is turned on to rotate the disc 6. Since the pull rod 8 and the disc 6 are both rotatably connected to the connecting plate 7, when the disc 6 rotates, the pull rod 8 will move back and forth, thereby driving the U-shaped mounting seat 9 to move back and forth, and then driving the two steel brushes 11 to move back and forth, brushing off a large amount of paint and other debris on the galvanized substrate 12, and then degreasing and pickling a small amount of paint and other debris, so that the processing efficiency can be improved.

[0027] When the steel brush 11 moves back and forth, it can scratch the surface of the galvanized substrate 12 to form wavy patterns, which is convenient for subsequent galvanizing of the surface of the galvanized substrate 12 and improves the adhesion between the galvanized layer 120 and the galvanized substrate 12.

[0028] In order to further prevent dust from floating and polluting the working environment when cleaning the galvanized substrate 12, the utility model is equipped with a collection box 13 on the processing tank 1, a fan 14 is arranged on one side of the collection box 13, and a dust suction nozzle 15 is arranged on the other side of the collection box 13.

When working, when the steel brush 11 starts to clean the galvanized substrate When debris on the plate 12 is removed, the fan 14 is turned on, and the dust brushed off by the steel brush 11 is absorbed by the collecting box 13 and the dust suction nozzle 15 in turn. At this time, the filter screen 16 arranged in the collecting box 13 will block the dust, so that the dust remains in the collecting box 13, which can prevent the dust from entering the fan 14 and protect the fan 14 well. When the pull rod 8 moves back and forth, it will drive the U-shaped vibration rod 17 to move back and forth, so that the U-shaped vibration rod 17 continuously hits the filter screen 16 to prevent dust from clogging the filter screen 16. In this way, the dust absorption effect can be guaranteed, and then the galvanized substrate 12 can be continuously cleaned, the processing efficiency can be improved, and the working environment can be protected, which is conducive to continuous production.
