[0030] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0031] Embodiment 1

[0032] Please refer to Figures 1-5 As shown, a pretreatment device for hot-dip galvanizing includes a barrel body 1 and two groups of plate bodies 2. The two groups of plate bodies 2 are distributed on both sides of the barrel body 1. A first notch 101 is opened on the upper side of the barrel body 1, and a filter cartridge 3 is installed in the first notch 101. Second notches 201 are opened on the outer surfaces of the two groups of plate bodies 2, and a lifting mechanism 4 is arranged in the second notches 201. A connecting plate 5 is connected to the lifting mechanism 4, and one end of the connecting plate 5 away from the lifting mechanism 4 is fixedly connected to a cover plate 6. A second driving module 7 is installed on the lower side of the cover plate 6. The output end of the second driving module 7 is fixedly connected to a frame body 8. Second threaded rods 10 are threadedly connected to opposite sides of the frame body 8, and rotary knobs 9 are fixedly connected to the outer sides of the second threaded rods 10. Rotating parts 11 are rotatably connected to both sides of the lower end of the cover plate 6. A load-bearing part 202 is fixedly connected to the upper side of the left plate body 2. A number of filter holes 303 are equidistantly arranged on the outer surface of the filter cartridge 3. The size of the cover plate 6 is adapted to that of the first notch 101. Ear plates 302 are fixedly connected to both sides of the top of the filter cartridge 3. A ring plate 301 is fixedly connected to the outer surface of the filter cartridge 3. Ear plates 302 are fixedly connected to both sides of the top of the filter cartridge 3. The size of the rotating part 11 is adapted to that of the ear plate 302.

[0033] In this embodiment, first, the staff places the steel material to be galvanized into the interior of the frame 8. Then, the two turning knobs 9 are turned, and the turning knobs 9 drive the second threaded rod 10 to move into the interior of the frame 8. When the two second threaded rods 10 abut against the steel material, the two turning knobs 9 are released, and the steel material can be clamped and fixed. Secondly, the lifting mechanism 4 drives the connecting plate 5 and the cover plate 6 to descend. At the same time, the rotating member 11 is rotated to ensure that the rotating member 11 can pass through the through hole on the ear plate 302, so that the cover plate 6 abuts against the upper side of the filter cylinder 3. Then, the second driving module 7 is turned on, and the second driving module 7 drives the frame 8 to rotate, and then drives the steel material to rotate. During the rotation of the steel material, the flow intensity of the sulfuric acid solution generated can wash away the impurities on the surface of the steel material, thereby improving the efficiency of hot-dip galvanizing pretreatment. Since the cover plate 6 abuts against the filter cylinder 3, the sulfuric acid solution is prevented from leaking. The washed impurities are blocked by the filter holes 303 and will be stored inside the filter cylinder 3, avoiding the problem of polluting the sulfuric acid solution in the barrel 1 and causing a large amount of sulfuric acid solution to be wasted. When it is necessary to clean the impurities in the filter cylinder 3, the rotating member 11 is rotated again at this time, so that the rotating member 11 abuts against the ear plate 302. Then, when the steel material is lifted by the lifting mechanism 4, the filter cylinder 3 is separated from the barrel 1 through the rotating member 11 and the ear plate 302, so that the impurities in the filter cylinder 3 can be cleaned.

[0034] Embodiment 2

[0035] Please refer to Figure 2 As shown, the lifting mechanism 4 includes a first driving module 401. The first driving module 401 is installed on the upper side of the load-bearing member 202. The output end of the first driving module 401 penetrates through the load-bearing member 202 and is fixedly connected with a driving wheel 402. The driving wheel 402 is connected with a driven wheel 404 through a belt 403. Both the lower sides of the driving wheel 402 and the driven wheel 404 are fixedly connected with a first threaded rod 405. The first threaded rod 405 extends into the first notch 101 and is rotationally connected with the plate body 2. Two sliding rods 406 are further arranged in the first notch 101, and the two sliding rods 406 are symmetrically distributed on both sides of the first threaded rod 405. The outer surface of the first threaded rod 405 is threadedly connected with a slider 407, and the slider 407 is slidably connected with the two sliding rods 406. The outer sides of the two sliders 407 are fixedly connected with the connecting plate 5.

[0036] In this embodiment, first, the first driving module 401 is turned on. The first driving module 401 drives the driving wheel 402 to rotate, and then drives the driven wheel 404 to rotate through the belt 403, so that the driving wheel 402 and the driven wheel 404 drive the first threaded rod 405 below to rotate. When the first threaded rod 405 rotates, it drives the two sliders 407 to move up and down, so that the steel material in the frame 8 can be driven to move up and down.

[0037] The working principle and usage process of this device are as follows: First, the staff puts the steel material to be galvanized into the interior of the frame 8. Then, turn the two side knobs 9. Further, the knob 9 drives the second threaded rod 10 to move into the interior of the frame 8. When the two side second threaded rods 10 touch the steel material, release the two side knobs 9, and the steel material can be clamped and fixed. Secondly, turn on the first driving module 401. The first driving module 401 drives the driving wheel 402 to rotate. Further, the driven wheel 404 is driven to rotate through the belt 403, so that the driving wheel 402 and the driven wheel 404 drive the first threaded rod 405 below to rotate. When the first threaded rod 405 rotates, the two side sliders 407 are driven to lift and lower, and then the connecting plate 5 and the cover plate 6 are driven to descend. During the descent of the connecting plate 5 and the cover plate 6, the rotating member 11 is rotated at the same time to ensure that the rotating member 11 can pass through the through hole on the ear plate 302, so that the cover plate 6 abuts against the upper side of the filter cartridge 3. Then, turn on the second driving module 7. The second driving module 7 drives the frame 8 to rotate, and then drives the steel material to rotate. During the rotation of the steel material, the flow intensity of the sulfuric acid solution generated can wash away the impurities on the surface of the steel material, thereby improving the efficiency of hot-dip galvanizing pretreatment. Since the cover plate 6 abuts against the filter cartridge 3, the leakage of the sulfuric acid solution is avoided. The washed impurities are blocked by the filter holes 303 and will be stored inside the filter cartridge 3, avoiding the problem of polluting the sulfuric acid solution in the barrel 1 and causing a large amount of waste of sulfuric acid solution. When it is necessary to clean the impurities in the filter cartridge 3, rotate the rotating member 11 again at this time, so that the rotating member 11 abuts against the ear plate 302. Further, when the steel material is lifted by the lifting mechanism 4, the filter cartridge 3 is separated from the barrel 1 through the rotating member 11 and the ear plate 302, so that the impurities in the filter cartridge 3 can be cleaned up.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
