Description

Technical Field

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

[0002] A hot-dip galvanizing tank is a container used to hold molten zinc and allow the workpiece to undergo the hot-dip galvanizing process. Its function is to provide a stable reaction environment for hot-dip galvanizing, so that the pre-treated workpiece can fully contact the zinc liquid and form a uniform and dense zinc coating on the surface, thereby achieving the purposes of corrosion prevention and aesthetics.

[0003] Currently, in the cleaning process of hot-dip galvanizing tanks, some manufacturers still use manual cleaning methods due to cost considerations. This traditional approach is extremely inefficient and requires a large amount of manpower. Even with the help of semi-automatic cleaning tools, a large amount of zinc dross will still remain in the hot-dip galvanizing tank, which will then have to be collected manually one by one. This is not only time-consuming and labor-intensive, but also extremely inconvenient, resulting in poor overall cleaning results.

[0004] In order to facilitate the cleaning of hot-dip galvanizing tanks and improve cleaning efficiency, this application proposes a hot-dip galvanizing tank cleaning device. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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. Example 1

[0023] Please see Figure 1 , Figure 4 - Figure 5A hot-dip galvanizing tank cleaning device includes a frame plate 1, a hot-dip galvanizing tank body 6 is provided on the inner side of the frame plate 1, a baffle 5 is provided at the top of the frame plate 1 in front of the hot-dip galvanizing tank body 6, hydraulic rods 2 are fixedly connected to the top of the frame plate 1 at the four corners of the hot-dip galvanizing tank body 6, connecting plates 3 are fixedly connected to the driving ends of the hydraulic rods 2, sliding plates 4 are fixedly connected to the opposite ends of the connecting plates 3 on the left and right sides, movable blocks 10 are slidably connected to the middle of the left and right sides of the inner wall of the sliding plates 4, fixed blocks 11 are fixedly connected to the bottom of the movable blocks 10, concave frames 14 are fixedly connected to the opposite side of the bottom end of the fixed blocks 11, rotating rods 16 are rotatably connected to the lower part of the inner wall of the concave frames 14 and penetrate through the front and rear sides of the concave frames 14, support plates 15 are fixedly connected to the front and rear ends of the rotating rods 16, and buckets 7 are fixedly connected to the bottom ends of the support plates 15 on the front and rear sides.

[0024] The top of the frame plate 1 is fixedly connected to the left and right sides of the front side of the hot-dip galvanizing tank body 6. The inner wall of the baffle 5 is provided with slots 23 on both sides. The shape of the top of the positioning bolt 21 matches the shape of the inner wall of the slot 23. The upper part of the front end of the positioning bolt 21 is provided with a slot 22. The top of the baffle 5 is rotatably connected to the opposite side of the slot 23. The distance between the upper and lower ends of the slot 24 is the same as the distance between the upper and lower ends of the inner wall of the slot 22. The middle of the left and right sides of the top of the frame plate 1 is fixedly connected to the transition block 18. The inner wall of the transition block 18 is threaded with bolts 19, which penetrate the left and right sides of the transition block 18. The opposite end of the bolt 19 is fixedly connected to the pressure plate 20.

[0025] To further explain, firstly, multiple hydraulic rods 2 are activated simultaneously, their driving ends pushing the connecting plate 3, which in turn drives the sliding plate 4 to rise to a suitable height. Next, the frame plate 1 is moved to the outside of the hot-dip galvanizing tank body 6, so that it is locked onto the outer wall of the hot-dip galvanizing tank body 6. Then, the holes and slots 23 on both sides of the inner wall of the baffle 5 are fitted onto the outer wall of the positioning bolt 21 until the bottom of the baffle 5 contacts the top of the frame plate 1. At this time, the two side clamping plates 24 are rotated so that they are locked into the clamping slots 22, which strengthens the limiting of the baffle 5. After that, the two side bolts 19 are rotated respectively, and the bolts 19 drive the pressure plate 20 to move towards both sides of the hot-dip galvanizing tank body 6 until the opposite ends of the pressure plate 20 are attached to the two ends of the hot-dip galvanizing tank body 6, thus completing the clamping of the two ends of the hot-dip galvanizing tank body 6. Through the above operations, the cleaning device is securely limited on the outside of the hot-dip galvanizing tank body 6, improving its operational stability.

[0026] All four corners of the bottom of the frame plate 1 are equipped with casters, and all casters are equipped with brake mechanisms to limit the free movement of the casters. Meanwhile, the top of the chute plate 4 is equipped with a controller that is electrically connected to multiple electric drive components in the device. The edge of the bucket 7 matches the shape of both sides of the inner wall edge of the hot-dip galvanized tank body 6. Example 2

[0027] Please seeFigure 2 - Figure 3 Further, based on Embodiment 1, gears 17 are fixedly connected to the outer wall of the rotating rod 16 inside the concave frame 14, racks 13 are slidably connected to the inner wall of the opposite end of the retaining block 11, and the opposite ends of the racks 13 are meshed with the opposite ends of the outer diameter of the gears 17. Electric push rods 12 are fixedly connected to the inner wall of the opposite side of the top of the retaining block 11, and the driving ends of the electric push rods 12 are fixedly connected to the top of the racks 13. A bidirectional screw 9 is rotatably connected to the inner wall of the middle of the left end of the slide plate 4. The left and right sides of the outer wall of the bidirectional screw 9 are threaded to the inner walls of the movable blocks 10 on the left and right sides respectively. A motor 8 is fixedly connected to the middle of the right end of the slide plate 4, and the driving end of the motor 8 passes through the inner wall of the slide plate 4 and is fixedly connected to the right end of the bidirectional screw 9.

[0028] To further explain, after the device is fixed, the cleaning stage begins. First, the hydraulic rod 2 is controlled to retract, causing the chute plate 4 to move downwards. At this time, the bucket 7 moves downwards with the chute plate 4, and its edge contacts both sides of the inner wall of the hot-dip galvanizing tank body 6, gradually scraping off the galvanized coating on both sides of the inner wall. When the bottom of the bucket 7 contacts the bottom edge of the inner wall of the hot-dip galvanizing tank body 6, the hydraulic rod 2 is activated again to push the chute plate 4 upwards. At the same time, the electric push rod 12 is activated to push the rack 13 downwards. The gear 17 meshing with one end of the rack 13 rotates accordingly, driving the rotating rod 16 to rotate. Then, with the help of the support plate 15, the two buckets 7 on both sides rotate in opposite directions, gradually changing from a horizontal state to a vertical state. During this process, the bottom of the bucket 7 contacts the bottom of the inner wall of the hot-dip galvanizing tank body 6, scraping off the galvanized coating in that part. When the bucket 7 is completely upright, the hydraulic rod 2 stops running. At this time, the edge of the bucket 7 is still in contact with the inner wall of the hot-dip galvanizing tank body 6, and the previously scraped galvanized coating is pushed between the two buckets 7.

[0029] Then, the motor 8 is started, and its drive end drives the bidirectional screw 9 to rotate, causing the movable blocks 10 on both sides to move in opposite directions along the threads. Under the traction of multiple components, the bucket 7 moves accordingly, continuing to scrape off the galvanization on the inner wall of the hot-dip galvanizing tank body 6. The scraped-off galvanization continuously accumulates between the two buckets 7 until the opposite ends of the two buckets 7 are pressed together, thus closing and collecting the galvanization. Next, the hydraulic rod 2 is started again to push the slide plate 4 upward, so that the bucket 7 is away from the inner wall of the hot-dip galvanizing tank body 6. Then, the clamping plate 24 is rotated out from the clamping slot 22, the baffle 5 is removed, and the bolts 19 are reversed to move the pressure plate 20 away from both ends of the hot-dip galvanizing tank body 6. Finally, the cleaning device is pushed to the designated position, the motor 8 is started to reverse, so that the movable blocks 10 on both sides move in opposite directions, separating the closed buckets 7 and pouring out the removed galvanization.

[0030] Working principle: First, multiple hydraulic rods 2 are started simultaneously, causing their drive ends to push the connecting plate 3 and the sliding plate 4 to rise to a certain height. Then, the frame plate 1 is moved to the outside of the hot-dip galvanizing tank body 6 and locked onto the outer wall of the hot-dip galvanizing tank body 6. Next, the holes and slots 23 on both sides of the inner wall of the baffle 5 are fitted onto the outer wall of the positioning bolt 21 until the bottom of the baffle 5 contacts the top of the frame plate 1. Then, the two side clamping plates 24 are rotated so that the clamping plates 24 are locked into the slots 22, which strengthens the limiting effect on the baffle 5. Then, the two side bolts 19 are rotated respectively, so that the bolts 19 and the pressure plate 20 are moved towards both sides of the hot-dip galvanizing tank body 6 until the opposite ends of the pressure plate 20 are attached to the two ends of the hot-dip galvanizing tank body 6, thereby forming a clamping effect on the hot-dip galvanizing tank body 6. Through the above operations, the limiting effect of the cleaning device on the outside of the hot-dip galvanizing tank body 6 is ensured, and the stability of the cleaning device when running on the side is improved.

[0031] Next, the hydraulic rod 2 is retracted, causing the chute plate 4 to move downwards. Simultaneously, as the chute plate 4 moves downwards, the edge of the bucket 7 contacts both sides of the inner wall of the hot-dip galvanizing tank 6, gradually scraping off the galvanized coating. This continues until the bottom of the bucket 7 contacts the bottom edge of the inner wall of the hot-dip galvanizing tank 6. Then, the hydraulic rod 2 is activated, pushing the chute plate 4 upwards. Simultaneously, the electric push rod 12 is activated, pushing the rack 13 downwards. The gear 17 meshing with it rotates, causing the rotating rod 16 to rotate as well. Through the support plate 15, the two buckets 7 rotate in opposite directions, gradually changing from a horizontal to an upright position. During this process, the bottom of the bucket 7 contacts the bottom of the inner wall of the hot-dip galvanizing tank 6, scraping off the galvanized coating in that area. Once the bucket 7 is fully upright, the hydraulic rod 2 is stopped. At this point, the edge of the bucket 7 is still in contact with the inner wall of the hot-dip galvanizing tank 6, and the previously scraped coating remains. The galvanized material is pushed into the area between the two buckets 7. Then, the motor 8 is started, causing its drive end to rotate with the bidirectional screw 9, which causes the two movable blocks 10 to move in opposite directions along the threads. At the same time, under the traction of multiple components, the buckets 7 are moved, scraping off the galvanized material from the inner wall of the hot-dip galvanizing tank body 6. The scraped-off galvanized material continuously accumulates between the two buckets 7 until the opposite ends of the two buckets 7 are pressed together, forming a closed collection of galvanized material. Then, the hydraulic rod 2 is started to continue pushing the slide plate 4 upward until the buckets 7 are away from the inner wall of the hot-dip galvanizing tank body 6. Then, the clamping plate 24 is rotated out of the clamping slot 22, and the baffle 5 is removed from the top of the hot-dip galvanizing tank body 6. Then, the bolts 19 are reversed so that the pressure plate 20 is away from both ends of the hot-dip galvanizing tank body 6. Then, the cleaning device is pushed to the designated position, and the motor 8 is started to reverse, causing the two movable blocks 10 to move in opposite directions, causing the closed buckets 7 to separate, thereby pouring out the removed galvanized material.
