Description

Technical Field

[0001] This utility model relates to the field of hot-dip galvanizing technology, specifically to a slag removal device for hot-dip galvanizing. Background Technology

[0002] There are many reasons why dross may form during hot-dip galvanizing. Here are some possible factors: The presence of impurities such as oil and scale on the steel surface cannot be completely removed during the hot-dip galvanizing process, leading to dross formation in the galvanizing pot. Uneven coating thickness, with some areas having a thinner zinc layer, also makes dross more likely. Excessive immersion time or excessively high temperature can cause the coating to thicken excessively, resulting in dross formation in the galvanizing pot.

[0003] Existing methods for removing dross from hot-dip galvanizing typically involve manual cleaning or using electrically controlled cleaning frames to scoop dross from the galvanizing tank. However, both of these methods suffer from incomplete dross removal, failing to effectively guarantee the quality of galvanized parts. Utility Model Content

[0004] To address the problems in the background art, this utility model proposes a dross cleaning device for hot-dip galvanizing. This utility model can efficiently clean the dross generated during galvanizing, ensuring the quality of galvanized parts.

[0005] To solve the above problems, the present invention adopts the following technical solution: a slag cleaning device for hot-dip galvanizing, comprising a galvanizing tank, two mounting seats and two crossbeams. The two mounting seats are respectively disposed on the left and right sides of the top of the galvanizing tank. The two crossbeams are correspondingly disposed on the two mounting seats. Two sliding components are correspondingly disposed on the two crossbeams. Two lifting guide rails are correspondingly disposed on the two sliding components. The same cleaning frame is detachably connected to the two lifting guide rails by connecting bolts. The cleaning frame includes a frame body and a rear cover. Both the frame body and the rear cover are mesh structures. The rear cover is hinged to the rear side of the frame body and fixed to the frame body by connecting bolts. The middle part of the front side of the frame body is a funnel structure that gradually narrows inward toward the rear side of the frame body.

[0006] Furthermore, the funnel structure includes two symmetrically arranged bent plates, each comprising a vertical plate and an inclined plate. The vertical plate is disposed on the front side of the frame body and its periphery is connected to the frame body. One end of the inclined plate is connected to the vertical plate, and the end of the inclined plate away from the vertical plate is inclined toward the interior of the frame body. The two inclined plates are spaced apart from each other to form a material passage, which gradually narrows toward the center of the frame body.

[0007] Furthermore, a one-way valve is provided at the inner end of the material passage corresponding to the ends of the two inclined plates. The one-way valve is used to prevent scum inside the frame body from leaking out of the material passage.

[0008] Furthermore, the one-way valve includes two overlapping sealing plates, which are elastically hinged to the ends of the two inclined plates in a one-to-one correspondence, and the ends of the two sealing plates that are in contact with each other protrude toward the interior of the frame body.

[0009] Furthermore, the sliding assembly includes an electric slide rail and a slider. The electric slide rail is mounted on the corresponding crossbeam and is connected to an external power source. The slider is slidably mounted on the electric slide rail, and the lifting guide rail is connected to the corresponding slider by fixing bolts.

[0010] The beneficial effects of this invention are as follows: This invention controls the lateral movement of the cleaning frame by setting two sliding components and controls the vertical height of the cleaning frame by setting lifting guide rails. This ensures that the cleaning frame can clean slag at different liquid levels in the galvanizing tank. Since both the frame body and the rear cover are mesh structures, the galvanizing liquid can be smoothly discharged from the cleaning frame, while only the slag is collected. Due to the funnel-shaped structure of the frame body, the slag in the galvanizing tank can smoothly enter the frame body and cannot easily leak directly from the funnel opening, preventing the collected slag from re-entering the galvanizing tank and affecting the quality of the galvanized parts. Opening the rear cover allows the collected slag to be discharged, facilitating the cleaning of the cleaning frame. Compared with traditional slag cleaning methods, this invention can efficiently clean the slag generated during galvanizing, ensuring the quality of the galvanized parts. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This invention controls the lateral movement of the cleaning frame 6 by using two sliding components 4 and the vertical height of the cleaning frame 6 by using a lifting guide rail 5. This ensures that the cleaning frame 6 can clean slag at different liquid levels in the galvanizing tank 1. Since both the frame body 7 and the rear cover 8 are mesh structures, the galvanizing liquid can be smoothly discharged from the cleaning frame 6, while only the slag is collected. Due to the funnel-shaped structure of the frame body 7, the slag in the galvanizing tank 1 can smoothly enter the frame body 7 and cannot easily leak directly from the funnel opening, preventing the collected slag from re-entering the galvanizing tank 1 and affecting the quality of the galvanized parts. Opening the rear cover 8 allows the collected slag to be discharged, facilitating the cleaning of the cleaning frame 6. Compared to traditional slag cleaning methods, this invention can efficiently clean the slag generated during galvanizing, ensuring the quality of the galvanized parts.

Two sliding components 4 are correspondingly disposed on the two crossbeams 3. Two lifting guide rails 5 are correspondingly disposed on the two sliding components 4. The same cleaning frame 6 is detachably connected to the two lifting guide rails 5 by connecting bolts. The cleaning frame 6 includes a frame body 7 and a rear cover 8. Both the frame body 7 and the rear cover 8 are mesh structures. The rear cover 8 is hinged to the rear side of the frame body 7 and fixed to the frame body 7 by connecting bolts. The middle of the front side of the frame body 7 is a funnel structure that gradually narrows inward toward the rear side of the frame body 7.

[0018] Furthermore, the funnel structure includes two symmetrically arranged bent plates 9, each of which includes a vertical plate 10 and an inclined plate 11. The vertical plate 10 is disposed on the front side of the frame body 7 and its periphery is connected to the frame body 7. One end of the inclined plate 11 is connected to the vertical plate 10, and the end of the inclined plate 11 away from the vertical plate 10 is inclined towards the interior of the frame body 7. The two inclined plates 11 are spaced apart from each other to form a material passage 12, which is gradually narrowed towards the center of the frame body 7.

[0019] Furthermore, a one-way valve 13 is provided at the inner end of the material passage 12 corresponding to the ends of the two inclined plates 11. The one-way valve 13 is used to prevent scum in the frame body 7 from leaking out of the material passage 12.

[0020] Furthermore, the one-way valve 13 includes two overlapping sealing plates 14, which are elastically hinged to the ends of the two inclined plates 11 in a one-to-one correspondence, and the ends of the two sealing plates 14 that are in contact with each other protrude toward the interior of the frame body 7.

[0021] Furthermore, the sliding assembly 4 includes an electric slide rail 15 and a slider 16. The electric slide rail 15 is mounted on the corresponding crossbeam 3 and is connected to an external power source. The slider 16 is slidably mounted on the electric slide rail 15. The lifting guide rail 5 is connected to the corresponding slider 16 by fixing bolts.

[0022] This invention controls the lateral movement of the cleaning frame 6 by using two sliding components 4 and the vertical height of the cleaning frame 6 by using a lifting guide rail 5. This ensures that the cleaning frame 6 can clean slag at different liquid levels in the galvanizing tank 1. Since both the frame body 7 and the rear cover 8 are mesh structures, the galvanizing liquid can be smoothly discharged from the cleaning frame 6, while only the slag is collected. Due to the funnel-shaped structure of the frame body 7, the slag in the galvanizing tank 1 can smoothly enter the frame body 7 and cannot easily leak directly from the funnel opening, preventing the collected slag from re-entering the galvanizing tank 1 and affecting the quality of the galvanized parts. Opening the rear cover 8 allows the collected slag to be discharged, facilitating the cleaning of the cleaning frame 6.
