[0002] Lead quenching is a common process step in the heat treatment and processing of steel wire, used to improve the mechanical properties and surface condition of the steel wire. However, after quenching, a layer of lead often remains on the surface of the steel wire, which will form a lead-attached phenomenon. If it is not cleaned in time, the residual lead will easily accumulate in the mold during the subsequent drawing process, causing mold blockage, increased wear, and even steel wire breakage, which seriously affects production efficiency and finished product quality.

[0003] Existing methods for removing residual lead from the surface of steel wire mainly rely on mechanical scraping, chemical cleaning, or scraping the residual lead from the surface of the steel wire using roller brushes, which can remove residual lead from the surface to a certain extent.

[0004] However, if the steel wire surface is hard or the residual lead particles have strong adhesion, the brush fibers are prone to wear and breakage, requiring frequent replacement to ensure cleaning efficiency. Utility Model Content

[0016] 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.

[0017] Please refer to the figure. This utility model provides a technical solution: a device for removing residual lead from the surface of steel wire after lead washing; Example 1: In order to effectively remove loose residual lead particles from the surface of the steel wire, a brushing box 2, a cleaning box 3, a spray box 4, a multi-stage water washing box 5 and a drying box 6 are fixedly installed on the surface of the base 1 from left to right. Several mounting holes 22 are opened on the periphery of the spray box 4. An inlet pipe 23 is fixedly installed on the top surface of the spray box 4. Multiple nozzles 24 are fixedly installed on the lower surface of the inlet pipe 23. The inner wall of the mounting hole 22 is movably connected to the outer wall of the nozzle 24. The steel wire passes through a brushing mechanism where rotating brush bristles remove loose residual lead particles from the surface. It then enters a cleaning tank 3 where a chemical treatment solution reacts with the residual lead to form a soluble complex. The steel wire then passes through a spray tank 4 where nozzles 24 further remove any remaining chemical treatment solution and complex from the surface. Finally, it passes through a multi-stage water washing tank 5 to thoroughly remove impurities from the surface of the steel wire.

[0018] A fan 25 is fixedly installed on the top of the drying box 6, and the air outlet of the fan 25 is located on the inner wall of the drying box 6. Finally, the steel wire passes through the drying box 6, where the fan 25 quickly dries the surface of the steel wire to prevent oxidation.

[0019] Example 2: Based on Embodiment 1, in order to facilitate the quick replacement of worn bristles, a connecting shaft 14 is fixedly installed at one end of the roller shaft 11, and a through keyway 12 is opened at the other end of the roller shaft 11. A limiting groove 13 is opened on the outer wall of the roller shaft 11 perpendicular to the keyway 12. A spring 15 is sleeved on the outer surface of the connecting shaft 14. A protruding key 17 is fixedly installed on the inner wall of the bottom end of the bushing 16. Several sets of equidistant long bristles 18 and short bristles 19 are inserted into the outer wall of the bushing 16. The long bristles 18 and short bristles 19 are staggered. The protruding key 17 is fitted into the keyway 12. The bushing 16 is slidably sleeved with the roller shaft 11. One end of the spring 15 abuts against the surface of the first sprocket 8 and the second sprocket 9, and the other end of the spring 15 abuts against the bottom end face of the roller shaft 11. When disassembling the bushing 16, pressing the bushing 16 backward squeezes the spring 15 fitted on the connecting shaft 14, causing the convex key 17 to disengage from the limiting groove 13. At the same time, rotating the bushing 16 ninety degrees makes the convex key 17 on the inner wall of the bushing 16 parallel to the keyway 12. At this time, the bushing 16 can slide along the inner wall of the keyway 12, thereby removing the bushing 16. The long bristles 18 penetrate deep into the gaps of the steel wire, and the short bristles 19 clean the surface, ensuring thorough removal of residual lead. The brushes are easy to replace, ensuring the elasticity and cleaning ability of the bristles, and further effectively removing loose residual lead particles from the surface of the steel wire, which is beneficial to improving the production efficiency and finished product quality of subsequent steel wire production steps.

[0020] Example 3: Based on Embodiment 1, in order to drive the long bristles 18 into the gaps of the steel wire and the short bristles 19 to clean the surface, a transmission mechanism for driving is fixedly installed on the side wall of the brushing box 2. The transmission mechanism includes: a motor 7, a first sprocket 8 rotatably mounted on the output end of the motor 7, a chain 10 embedded on the outer surface of the first sprocket 8, and a second sprocket 9 rotatably mounted on the side away from the first sprocket 8. The first sprocket 8 and the second sprocket 9 rotate synchronously through the chain 10, and the roller shaft 11 is rotatably connected to the first sprocket 8 and the second sprocket 9 through the connecting shaft 14. The motor 7 drives the first sprocket 8 to rotate, which in turn drives the second sprocket 9, which is mounted on the side away from the first sprocket 8, to rotate synchronously via the chain 10. Since the roller shaft 11 is rotatably connected to the first sprocket 8 and the second sprocket 9 via the connecting shaft 14, the long bristles 18 on the bushing 16 are driven to penetrate into the gaps of the steel wire while the short bristles 19 clean the surface, thus improving the cleaning efficiency of the steel wire.

[0021] Working principle: In actual use, the motor 7 first drives the first sprocket 8 to rotate, which in turn drives the second sprocket 9, which is mounted on the side away from the first sprocket 8, to rotate synchronously via the chain 10. Since the roller shaft 11 is rotatably connected to the first sprocket 8 and the second sprocket 9 via the connecting shaft 14, the rotation of the first sprocket 8 and the second sprocket 9 simultaneously drives the long bristles 18 on the bushing 16 to penetrate deep into the gaps in the steel wire, while the short bristles 19 clean the surface, improving the cleaning efficiency of the steel wire. Next, the wire enters the cleaning tank 3, where the chemical treatment solution reacts with the residual lead to form a soluble complex. Then, the steel wire passes through the spray tank 4, where the spray nozzles 24 further remove any remaining chemical treatment solution and complex from the surface. Finally, the wire passes through multiple... The first washing tank 5 thoroughly removes impurities from the surface of the steel wire. Finally, the steel wire passes through the drying box 6, where the blower 25 quickly dries the surface of the steel wire to prevent oxidation. When disassembling the bushing 16, pressing the bushing 16 backward squeezes the spring 15 fitted on the connecting shaft 14, causing the convex key 17 to disengage from the limiting groove 13. At the same time, rotating the bushing 16 ninety degrees makes the convex key 17 on the inner wall of the bushing 16 parallel to the keyway 12. At this time, the bushing 16 can slide along the inner wall of the keyway 12, thus allowing the bushing 16 to be removed for easy replacement. This ensures the elasticity and cleaning ability of the bristles, further effectively removing loose residual lead particles from the surface of the steel wire, which is beneficial to improving the production efficiency and finished product quality of subsequent steel wire production steps.
