Description

Technical Field

[0001] This utility model relates to the field of pickling mechanism technology, and in particular to a pickling mechanism for surface treatment of tubular materials. Background Technology

[0002] During processing, transportation, and storage, the surface of tubular materials is prone to oxidation upon contact with oxygen in the air, forming an oxide scale. For example, a layer of oxide scale, mainly composed of ferric oxide and magnetite, will form on the surface of steel tubular materials. This oxide scale can affect the subsequent processing and performance of the tubular materials, so pickling is used. Pickling is a chemical cleaning method that mainly uses acid solutions to remove oxides, rust, oil, and other impurities from the metal surface.

[0003] Pickling machines for surface treatment of tubular materials typically utilize hydrochloric acid to chemically react with the iron oxide scale on the surface of the tubular material, generating iron salts that are soluble in the acid solution, thereby dissolving and removing the iron oxide scale.

[0004] In the existing technology, some pickling machines cannot effectively clean tubular materials with hard scale formed by high-temperature sintering or thick and tightly adhered rust layers formed by long-term corrosion. The impurities on the surface of tubular materials are very stubborn. In addition, for some tubular materials with complex textures or depressions, the acid solution cannot fully contact the impurities in these areas and cannot be thoroughly cleaned. Therefore, a pickling mechanism for the surface treatment of tubular materials is proposed to solve the above problems. Utility Model Content

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by starting the motor, the first fixed column rotates under the drive of the motor, and the driving wheel rotates with the first fixed column. Then, the driven wheel is driven to rotate through the belt, realizing the rotation of the second fixed column. At this time, the brush sleeves outside the first and second fixed columns will brush the material. While brushing, the first internal spring is compressed. During the compression process, a reaction force is generated on the rubber plate. The rubber plate squeezes the brush sleeve outward, making the brush sleeve contact the material more tightly and ensuring the cleaning effect.

This allows the mounting base to be quickly installed inside the box, and the acidic liquid inside can be recycled under the filtration action of the second filter plate. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of an acid pickling mechanism for surface treatment of tubular materials, comprising a housing 1. The housing 1 serves as the main container of the entire acid pickling mechanism, possessing sufficient strength and corrosion resistance to hold acidic liquid and the tubular material to be treated. A motor 2 is fixedly connected to the outer left side of the housing 1, serving as a power source to provide power for the operation of the entire acid pickling mechanism. A fixed column 3 is fixedly connected to the drive end of the motor 2, enabling it to rotate stably within the housing 1 under the drive of the motor 2. The other end of the fixed column 3 is rotatably connected to the inner right side of the housing 1. A second fixed column 4 is rotatably connected inside the housing 1, also rotatably connected within the housing 1. The two columns cooperate spatially to jointly undertake the task of washing the material.

[0034] Fixed sleeve shafts 5 are fixedly connected to the exterior of both fixed column 3 and fixed column 4. Multiple cavities 6 are formed inside fixed sleeve shafts 5. Springs 7 are fixedly connected to the inner walls of the cavities 6, and rubber plates 8 are fixedly connected to the other ends of springs 7. The fixed sleeve shaft 5 is fixedly connected to the exterior of both fixed column 3 and fixed column 4, and the multiple cavities 6 inside are evenly distributed, providing space for springs 7 and rubber plates 8. Brush sleeves 9 are fixedly connected to the exterior of both fixed column 3 and fixed column 4. Springs 7 are in a pre-compressed state, providing outward elastic force to the rubber plates 8.

[0035] When the brush sleeve 9 is compressed by the material, the rubber plate 8 is forced inward to compress the spring 7, which is further compressed inside the cavity 6. Simultaneously, a reaction force pushes the rubber plate 8, causing it to further compress the brush sleeve 9, resulting in tighter contact between it and the material. The rubber plate 8 is externally slidably connected to the outside of the cavity 6, with the side of the rubber plate 8 furthest from the cavity 6 contacting the inside of the brush sleeve 9. The inner diameter of the brush sleeve 9 fits tightly with the fixing post 3, fixing post 4, and the rubber plate 8, allowing it to deform evenly when compressed by the rubber plate 8. This better conforms to the material surface for washing, effectively removing dirt, rust, and other impurities from the material surface.

[0036] A transmission assembly is provided on the outside of the fixed column 3, which can drive the fixed column 4 to rotate. The transmission assembly includes a drive wheel 10, which is internally and fixedly connected to the left side of the fixed column 3. The drive wheel 10 rotates synchronously with the fixed column 3. A belt 11 is fitted on the outside of the drive wheel 10. The belt 11 is made of a material with good flexibility and wear resistance, which can stably transmit power under the drive of the drive wheel 10.

[0037] A driven wheel 12 is fixedly connected to the left external side of the fixed column 4. The inner wall of the other end of the belt 11 is sleeved on the outside of the driven wheel 12. When the motor 2 drives the fixed column 3 to rotate, the driving wheel 10 rotates accordingly. Through the friction of the belt 11, the driven wheel 12 is driven to rotate, thereby realizing the rotation of the fixed column 4. Multiple fixed rods 13 are fixedly connected inside the box 1, which are used to place the materials to be pickled.

[0038] Reference Figures 4 to 5 A filter plate 14 is fixedly connected inside the housing 1, and a water pump 15 is fixedly connected to the right side of the housing 1. The filter plate 14 is mainly used to intercept large particles and debris in the cleaning liquid, preventing them from entering the subsequent pipeline system or damaging equipment such as the water pump 15. The water pump 15 is the key equipment for realizing the circulation of liquid inside the housing 1. One end of the water pump 15 is fixedly connected to a connecting pipe 16, which connects the water pump 15 to the inside of the housing 1. The other end of the water pump 15 is fixedly connected to a drain pipe 25, which has multiple water outlet holes 26. Driven by the water pump 15, the liquid inside the housing 1 is drawn into the connecting pipe 16, and then re-enters the housing 1 through the water outlet holes 26 of the drain pipe 25, forming a circulation.

[0039] An installation assembly is located on the outer right side of the housing 1. This assembly assists in filtration and includes a mounting base 17. The mounting base 17 is internally and fixedly connected to the external end of the connecting pipe 16 away from the water pump 15. A filter plate 18 is also fixedly connected inside the mounting base 17, providing a mounting foundation for the filter plate 18. The filter plate 18 is fixed inside the mounting base 17, and its main function is to further filter fine particles in the liquid, preventing them from entering the connecting pipe 16 and causing blockage.

[0040] The mounting base 17 has multiple limiting grooves 19 inside, and a locking post 20 is slidably connected to the inner wall of the limiting groove 19. The locking post 20 can slide stably up and down within the limiting groove 19. A handle 21 is fixedly connected to one side of the locking post 20, which facilitates the operator's operation of the locking post 20. Two protrusions 22 are fixedly connected to the side of the locking post 20 away from the handle 21. A second spring 23 is sleeved on the outside of the locking post 20, and one end of the second spring 23 is fixedly connected to the inner wall of the limiting groove 19.

[0041] The other end of the second spring 23 is fixedly connected to the outside of the locking post 20. The second spring 23 is sleeved on the outside of the locking post 20, with one end fixedly connected to the inner wall of the limiting groove 19 and the other end fixedly connected to the outside of the locking post 20. Its elastic coefficient is selected according to the movement resistance of the locking post 20 and the installation stability requirements of the mounting base 17 to ensure the smoothness and reliability of the installation and disassembly process.

[0042] Multiple slots 24 are provided on the right side of the housing 1. When the handle 21 is rotated and pressed, the locking post 20 drives the protrusion 22 into the slot 24 on the right side of the housing 1. After releasing the handle 21, the locking post 20 drives the protrusion 22 to return to its original position under the elastic action of the spring 23. The outer side of the locking post 20 is slidably connected to the inner wall of the slot 24, and the outer side of the protrusion 22 engages with the inner wall of the slot 24, thereby firmly installing the mounting base 17 inside the housing 1. Multiple retaining rings 27 are detachably connected to the outside of the drain pipe 25 to fix the drain pipe 25.

[0043] Working principle: First, place the box 1 in a suitable position, then put the material into the top of the fixing rod 13. At this time, the inside of the box 1 contains acidic liquid, and the material is soaked and reacted. Then, start the motor 2. Under the drive of the motor 2, the fixing column 3 rotates. When the fixing column 3 rotates, the drive wheel 10 also rotates. The driven wheel 12 is driven to rotate through the belt 11, thereby realizing the rotation of the fixing column 4. At this time, the brush sleeve 9 outside the fixing column 3 and the fixing column 4 will wash the material. During the washing process, the brush sleeve 9 will be squeezed. At this time, the rubber plate 8 is squeezed inward to compress the spring 7 inside. The spring 7 is compressed inside the cavity 6. When the spring 7 is compressed, it will generate a reaction force on the rubber plate 8. The rubber plate 8 further squeezes the brush sleeve 9 to make it contact the material more tightly, thereby ensuring the cleaning effect.

[0044] Rotate and press the handle 21, while the second spring 23 is compressed. When the locking pin 20 drives the protrusion 22 into the slot 24, release the handle 21. Under the elastic action of the second spring 23, the locking pin 20 drives the protrusion 22 to reset, so that the outside of the protrusion 22 engages with the inner wall of the slot 24, thereby installing the mounting base 17 inside the box 1. After cleaning, debris and residue will appear inside the liquid. Large particles will remain on the surface of the first filter plate 14 under the filtering action of the first filter plate 14. Small particles will not enter the inside of the connecting pipe 16 under the filtering action of the second filter plate 18. Then start the water pump 15. Driven by the water pump 15, the liquid inside the box 1 is drawn through the connecting pipe 16 and then enters the inside of the drain pipe 25. It then enters the inside of the box 1 again through the water outlet 26 for use.
