Technical Field

[0001] The utility model relates to the technical field of steel pipe processing, in particular to a steel pipe pickling device. Background Technique

[0002] During the manufacturing, transportation and storage processes, the surface of the steel pipe will be contaminated with pollutants such as oil, grease, and dust. These substances not only affect the appearance of the steel pipe but may also become the starting point of corrosion. After pickling, the natural oxide layer on the surface of the steel pipe will be removed, exposing a fresh metal surface.

[0003] The existing high-efficiency pickling device for steel pipes with the patent publication number CN209493634U includes a switch and a columnar spray head. During use, the clamping mechanism sequentially places the steel pipe into the pickling tank through the opening. After the proximity switch detects the columnar spray head, the transverse moving cylinder drives the columnar spray head to extend into the inner hole of the steel pipe. At the same time, the annular columnar spray head also surrounds the outer wall of the steel pipe. The clamping mechanism releases the steel pipe, and then the pickling solution passes through the columnar spray head and the annular columnar spray head to pickle the steel pipe, pickling the inner and outer surfaces of the steel pipe simultaneously, with high efficiency. After pickling, the pickling solution flows into the pickling tank, avoiding the outflow of the pickling solution and facilitating the subsequent collection and use of the pickling solution.

[0004] After pickling the above device, there will be some pickling solution that has not completely flowed out inside the steel pipe. When moving, it will flow out during the movement process, which is likely to cause harm to the operator. In view of the above problems, a steel pipe pickling device is proposed.

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

[0025] Please refer to Figures 1-4, in this embodiment, a steel pipe pickling device includes a moving table 11, a pickling tank 12, and a filter box 14. Two support blocks 16 are rotatably connected to the top of the filter box 14. One end of the two support blocks 16 away from the filter box 14 is fixedly connected to the bottom of the moving plate 13. Two sliding grooves 18 are formed in the moving plate 13. A slider 17 is slidably connected in the sliding groove 18. The bottom of the slider 17 is fixedly connected to a fixed block 15. One end of the fixed block 15 away from the slider 17 is rotatably connected to the filter box 14. An electric telescopic rod 29 is arranged between the two fixed blocks 15. The bottom of the electric telescopic rod 29 is rotatably connected to the top of the filter box 14. One end of the electric telescopic rod 29 away from the filter box 14 is rotatably connected to the bottom of the moving plate 13;

[0026] The filter box 14 is located in the pickling tank 12. Two stirring rods 26 are rotatably connected in the pickling tank 12. A driving component for driving the stirring rods 26 to rotate is installed on one side of the pickling tank 12. Two electric hydraulic rods 19 are fixedly connected to the bottom of the moving plate 13. One end of the electric hydraulic rod 19 away from the moving plate 13 is installed on the top of a fixed column 20. A sliding component for driving the fixed column 20 to slide is arranged on the moving table 11. During pickling, the driving component drives the stirring rods 26 to rotate to stir the pickling solution. When the steel pipe is pickled, the electric telescopic rod 29 starts to contract. One side of the filter box 14 is pulled by the electric telescopic rod 29 to tilt. One side of the filter box 14 moves upward. The filter box 14 drives the fixed block 15 to move upward. The fixed block 15 drives the slider 17 upward. The slider 17 slides upward in the sliding groove 18. The filter box 14 rotates on the support block 16. The steel pipe in the filter box 14 tilts to pour out the pickling solution in the steel pipe. After pouring, the electric telescopic rod 29 expands and contracts to drive one side of the filter box 14 to move downward. The electric hydraulic rod 19 starts to extend upward to drive the moving plate 13 to move, so that the filter box 14 is separated from the pickling tank 12. The sliding component drives the fixed column 20 to move, which is convenient for the staff to process the pickled steel pipe or transport it to the next step for processing.

[0027] The driving component includes a driven wheel 27 and a connecting rod 31. One end of the stirring rod 26 extending to the outside is fixedly connected to the driven wheel 27. Two groups of driving wheels 30 are fixedly connected to the connecting rod 31. The driving wheels 30 are drivingly connected to the driven wheel 27 through a crawler 28. The connecting rod 31 is rotatably connected to a fixing plate 33. One side of the fixing plate 33 is fixedly connected to one side of the pickling tank 12. A driving motor 32 for driving the connecting rod 31 to rotate is installed on the fixing plate 33. When the driving motor 32 starts to work, it drives the connecting rod 31 to rotate. As the connecting rod 31 rotates, the two groups of driving wheels 30 rotate along with the rotation of the connecting rod 31. The driving wheels 30 drive the driven wheel 27 to rotate through the crawler 28, and the driven wheel 27 drives the stirring rod 26 to rotate to stir the pickling solution. The rotation of the stirring rod 26 can break the bubbles attached to the surface of the steel pipe, making the pickling solution better contact with the surface of the steel pipe.

[0028] The sliding component includes an installation box 21 and a gear 22. A toothed plate 24 is fixedly connected to one side of the moving table 11. The toothed plate 24 meshes with the gear 22. One side of a group of fixed columns 20 is fixedly connected to the installation box 21. A rotating motor for driving the gear 22 to rotate is installed in the installation box 21. When the rotating motor in the installation box 21 starts to work, it drives the gear 22 to rotate. The gear 22 meshes with the toothed plate 24 to drive the fixed column 20 to move. The fixed column 20 drives the guide block 23 to slide in the guide groove 25, which facilitates the staff to process the pickled steel pipe or transport it to the next step for processing.

[0029] A guide block 23 is fixedly connected to the bottom of the fixed column 20. A guide groove 25 for cooperating with the guide block 23 to slide is formed at the top of the moving table 11. The cross-sections of the guide block 23 and the guide groove 25 are both T-shaped. By providing the T-shaped guide block 23 and guide groove 25, the movement of the fixed column 20 can be guided and limited.

[0030] Two groups of backing plates are arranged in the pickling tank 12. By providing the backing plates, the placement of the filter box 14 can be facilitated, and the steel pipe can be made to contact the pickling solution more completely. A water injection pipe is installed on one side of the pickling tank 12, through which pickling solution can be injected into or recovered from the pickling tank 12.

[0031] The working principle of the utility model is as follows: During pickling, the driving motor 32 starts to work, driving the connecting rod 31 to rotate. As the connecting rod 31 rotates, the two driving wheels 30 rotate along with the rotation of the connecting rod 31. The driving wheels 30 are connected to the driven wheels 27 through the crawler 28 to drive the driven wheels 27 to rotate. The driven wheels 27 drive the stirring rod 26 to rotate to stir the pickling solution. During the pickling process, bubbles may be generated and attached to the surface of the steel pipe, affecting the pickling effect. The rotation and stirring of the stirring rod 26 can help break these bubbles, enabling the pickling solution to better contact the surface of the steel pipe. When the pickling of the steel pipe is completed, the electric telescopic rod 29 starts to contract. One side of the filter box 14 is pulled by the electric telescopic rod 29 to tilt, and one side of the filter box 14 moves upward. The filter box 14 drives the fixed block 15 to move upward, and the fixed block 15 drives the slider 17 upward. The slider 17 slides upward in the chute 18. The filter box 14 rotates on the support block 16, and the steel pipe in the filter box 14 tilts to pour out the pickling solution in the steel pipe. After the pouring is completed, the electric telescopic rod 29 expands and contracts to drive one side of the filter box 14 to move downward. The electric hydraulic rod 19 starts to extend upward, driving the moving plate 13 to move, so that the filter box 14 is separated from the pickling tank 12. The rotating motor in the installation box 21 starts to work, driving the gear 22 to rotate. The gear 22 meshes with the toothed plate 24 to drive the fixed column 20 to move. The fixed column 20 drives the guide block 23 to slide in the guide groove 25, facilitating the staff to process the pickled steel pipe or transport it to the next step for processing.

[0032] The above is only the preferred embodiment of the present utility model, and it is not a limitation to the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
