Description

Technical Field

[0001] This utility model belongs to the field of copper tube processing technology, specifically relating to a copper tube surface oil spray recovery device. Background Technology

[0002] Online annealing is a crucial step in copper tube production. Before annealing, the copper tube surface is coated with a large amount of external oil. After induction heating, this oil becomes highly adhesive. During the coiling process, this adhesiveness causes the copper tubes to easily stick together, leading to a decrease in coiling quality. This directly affects the unloading process of the forming machine, as the stuck copper tubes can easily break during machine operation.

[0003] To address the aforementioned issues, existing technologies employ a protective cover and an oil spraying system. Specifically, the annealed copper tube passes through the protective cover while the oil spraying system applies an anti-sticking agent to the tube surface, forming a protective oil film to reduce the stickiness of the annealed copper tube and improve winding quality. However, this approach has limitations: it only collects the anti-sticking agent within the protective cover, leaving excess agent residue on the copper tube surface untreated. This excess agent drips onto the production workshop floor and material baskets during winding, causing environmental pollution and potentially harming the health of operators. Utility Model Content

[0004] The purpose of this invention is to provide a copper pipe surface oil recovery device to prevent excessive anti-sticking agent residue on the copper pipe surface, reduce anti-sticking agent dripping from the copper pipe surface, and reduce the impact on the environment and the health of operators.

[0005] The purpose of this utility model is achieved through the following technical solution: a copper pipe surface oil spraying and recovery device is provided, including: a protective cover, an oil spraying system, an oil removal component, and a recovery component. The protective cover has a cavity inside. The oil spraying system is set on the protective cover and sprays an anti-sticking oil agent onto the copper pipe. The oil removal component is set in the cavity to remove the anti-sticking oil agent from the surface of the copper pipe. The recovery component is connected to the protective cover and is used to recover the anti-sticking oil agent.

[0006] Preferably, the degreasing assembly includes a degreasing ring tube, through which a copper tube passes, and at least a portion of the inner wall of the degreasing ring tube is in contact with the outer surface of the copper tube.

[0007] Preferably, the oil removal ring pipe includes a contact section and an oil guiding section. The cross-section of the contact section is circular, and the cross-section of the oil guiding section is right-angled trapezoidal. The inner diameter of the contact section is smaller than the inner diameter of the oil guiding section.

[0008] Preferably, a brush is provided on the lower inner wall of the contact section, and the brush is in contact with the outer surface of the copper tube.

[0009] Preferably, the degreasing assembly further includes an air nozzle disposed on the outside of the copper tube.

[0010] Preferably, the protective cover also includes a guide nozzle and a fastening ring. The two ends of the protective cover are provided with reserved holes for installing the guide nozzle. The outer sides of the two ends of the protective cover are provided with a second external thread. The fastening ring is provided with a second internal thread that mates with the second external thread. The fastening ring presses the guide nozzle tightly through the thread engagement.

[0011] Preferably, the guide nozzle is provided with a bearing hole, and the guide nozzle is provided with a frustum groove coaxial with the bearing hole near the copper tube insertion end, the inner diameter of the frustum groove gradually decreasing from the port to the inside.

[0012] Preferably, the guide nozzle is made of graphite.

[0013] Preferably, the recovery assembly includes an oil collection tank and a recovery pneumatic quick connector, the oil collection tank being connected to the cavity via the recovery pneumatic quick connector.

[0014] Due to the adoption of the above technical solution, this utility model has the following advantages:

[0015] By setting up an oil removal ring, the outer surface of the copper pipe comes into contact with the inner wall of the oil removal ring, removing the anti-sticking agent from the surface of the copper pipe. This prevents excessive oil residue from remaining on the outer surface of the copper pipe, reduces the formation of oil droplets after the copper pipe passes through the outlet and falls onto the ground or material basket, thus reducing environmental pollution and minimizing adverse effects on the health of operators.

[0031] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0032] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 A copper pipe surface oil spraying and recovery device includes a protective cover 1, an oil spraying system 2, an oil removal component 3, and a recovery component 5. The protective cover 1 has an internal cavity 12. The oil spraying system 2 is mounted on the protective cover 1 and sprays an anti-sticking agent onto the copper pipe 4. The oil removal component 3 is located in the cavity 12 and removes the anti-sticking agent from the surface of the copper pipe 4. The recovery component 5 is connected to the protective cover 1 and is used to recover the anti-sticking agent. Specifically, the protective cover 1 is made of corrosion-resistant stainless steel and is fixedly mounted on a receiving arm by a bracket 17 and bolts. The annealed copper pipe 4 passes directly through the middle of the protective cover 1. The protective cover 1 has an inlet 11 and an outlet 13 communicating with the cavity 12. The copper pipe 4 passes sequentially through the inlet 11, the oil spraying system 2, the oil removal component 3, and the outlet 13. The oil spraying system 2 includes an external oil supply tank, an external oil pipe 22, an oil valve, and an oil nozzle 21. Figure 5The fuel injector 21 includes a fuel injector body 211, a three-threaded connector 212, and a pneumatic quick-connector 213. The three-threaded connector 212 has first internal threads at both ends. The fuel injector body 211 and the pneumatic quick-connector 213 are assembled with the corresponding ends of the three-threaded connector 212 via these threads. The three-threaded connector 212 has a first external thread. The protective cover 1 has an internal threaded hole that mates with the three-threaded connector 212 and the first external thread. The assembled three-threaded connector 212 is threadedly connected to the protective cover 1. The fuel pipe 22 is directly inserted into the pneumatic quick-connector 213. Figure 4 The system includes several fuel injectors 21, evenly distributed around the axis of the copper tube 4. Preferably, there are four fuel injectors 21, which are spiral nozzles. This structure allows the fuel injectors 21 to simultaneously spray anti-sticking agent from different directions, increasing the uniformity of spraying. The oil removal assembly 3 is located at the rear end of the fuel injection system 2.

[0033] This utility model discloses a copper pipe surface oil spraying and recovery device. Before use, the oil nozzle 21 is connected to the oil supply tank via the oil pipe 22. The operator guides the annealed copper pipe 4 through the inlet 11, starts the power to move the copper pipe 4, and starts the oil spraying system 2. Anti-sticking oil agent is sprayed from the oil nozzle 21 to form an oil mist, which is evenly sprayed on the surface of the copper pipe 4. As the copper pipe 4 moves, the anti-sticking oil agent can be sprayed on the entire outer surface of the copper pipe 4. When passing through the degreasing component 3, the anti-sticking oil agent on the surface of the copper pipe 4 is removed, reducing the formation of oil droplets after the copper pipe 4 passes through the outlet 13 and falls to the ground or material basket, thereby reducing environmental pollution and adverse effects on the health of operators.

[0034] Further, please refer to Figure 2 and Figure 3 The degreasing assembly 3 includes a degreasing ring tube 31 through which a copper tube 4 passes. At least a portion of the inner wall of the degreasing ring tube 31 contacts the outer surface of the copper tube 4. Specifically, the degreasing assembly 3 is provided with a connecting rod 33, one end of which is connected to the inner wall of the protective cover 1, and the other end is connected to the outer surface of the degreasing ring tube 31. Preferably, the degreasing ring tube 31 is made of polytetrafluoroethylene composite material. When the copper tube 4, after being coated with anti-sticking agent, passes through the degreasing ring tube 31, the outer surface of the copper tube 4 contacts the inner wall of the degreasing ring tube 31, removing the anti-sticking agent from the surface of the copper tube 4. This reduces the formation of oil droplets on the ground or material basket after the copper tube 4 passes through the outlet 13, thereby reducing environmental pollution and minimizing adverse effects on the health of operators.

[0035] Further, please refer to Figure 6The oil removal ring pipe 31 includes a contact section 311 and an oil guiding section 312. The cross-section of the contact section 311 is circular, and the cross-section of the oil guiding section 312 is a right trapezoid. The inner diameter of the contact section 311 is smaller than the inner diameter of the oil guiding section 312. Specifically, the copper pipe 4 passes through the contact section 311 and the oil guiding section 312 in sequence. The inner diameter of the contact section 311 is the same as the outer diameter of the copper pipe 4. The inner wall of the contact section 311 contacts the surface of the copper pipe 4 to remove excess anti-sticking oil agent from the surface of the copper pipe 4. The anti-sticking oil agent that detaches from the surface of the copper pipe 4 drips into the protective cover 1 along the oil guiding section 312 under the action of gravity.

[0036] Furthermore, a brush 313 is provided on the lower inner wall of the contact section 311, and the brush 313 contacts the outer surface of the copper tube 4. Specifically, the brush 313 is made of nylon, and the tip of the brush 313 contacts the outer surface of the copper tube 4. With this structure, the copper tube 4 passes through the degreasing ring tube 31 more smoothly, and it is easier to remove excess anti-sticking agent, especially oil droplets, from the surface of the copper tube 4. The oil flows along the brush 313 to the oil guide section 312.

[0037] Further, please refer to Figure 3 and Figure 8 The degreasing assembly 3 also includes a jet nozzle 32, which is disposed on the outside of the copper pipe 4. Specifically, there are at least two sets of jet nozzles 32, one set above the copper pipe 4 and the other set on the side of the copper pipe. The degreasing assembly 3 also includes an external pneumatic cylinder, a valve, and a jet pipe 321. The installation principle of the jet nozzle 32 is the same as that of the fuel injector 21. One end of the jet nozzle 32 is inserted into the jet pipe 321, and the other end is fixedly disposed on the side wall of the protective cover 1 by a threaded connection, and passes through the protective cover 1 towards the outer surface of the copper pipe 4. During use, when the copper pipe 4 after being sprayed with oil passes through the air nozzle 32, the anti-sticking oil agent on the surface of the copper pipe 4 is blown away by the air nozzle 32 on the outside of the copper pipe 4. Most of the anti-sticking oil agent falls directly into the protective cover 1 after being blown away, or it concentrates on the lower surface of the copper pipe 4 after being blown away to form oil droplets. The oil droplets fall off due to gravity, equipment vibration or the blowing of the side air nozzle 32. Even if the oil droplets do not fall off, they are easier to remove when they come into contact with the oil removal ring pipe 31.

[0038] Further, please refer to Figure 2 and Figure 7The protective cover 1 also includes a guide nozzle 15 and a fastening ring 16. The two ends of the protective cover 1 are provided with reserved holes 121 for installing the guide nozzle 15. The outer sides of the two ends of the protective cover 1 are provided with second external threads 18. The fastening ring 16 is provided with a second internal thread 162 that mates with the second external thread 18. The fastening ring 16 presses the guide nozzle 15 together with the threaded engagement. Specifically, the cavity 12 is provided with a limiting step 122. The reserved holes 121 are coaxially connected to the cavity 11. The distance between the limiting step 122 and the port is the same as the length of the guide nozzle 15. The fastening ring 16 is provided with a frustum-shaped hole 161 that mates with the outer diameter of the guide nozzle 15. With this structure, the length of the guide nozzle 15 is standardized. When the guide nozzle 15 needs to be replaced, the fastening ring 16 is loosened to remove the guide nozzle 15.

[0039] Furthermore, the guide nozzle 15 is provided with a bearing hole 151, and a frustum groove 152 coaxial with the bearing hole 151 is provided on the guide nozzle 15 near the insertion end of the copper tube 4. The inner diameter of the frustum groove 152 gradually decreases from the port inward. Specifically, the inner diameter of the bearing hole 151 of each guide nozzle 15 can be different. By replacing guide nozzles 15 with different inner diameters, copper tubes 4 with different outer diameters can be used. When replacing, only the fastening ring 16 needs to be loosened to replace the guide nozzle 15, without replacing the entire device, thus reducing costs and improving replacement efficiency. The frustum groove 152 is provided to guide the insertion and exit of the copper tube 4, facilitating the passage of the copper tube through the protective cover 1.

[0040] Furthermore, the guide nozzle 15 is made of graphite. When the graphite material comes into contact with the copper tube 4, it will not scratch the copper tube 4, and it has good wear resistance.

[0041] Further, please refer to Figure 2 and Figure 9 The recovery assembly 5 includes an oil collection tank 51 and a recovery pneumatic quick connector 52. The oil collection tank 51 is connected to the cavity 12 via the recovery pneumatic quick connector 52. Specifically, the protective cover 1 also has an oil collection port 14 with a third internal thread. The main cross-section of the protective cover 1 is elliptical, and the oil collection port 14 is located at the bottom of the ellipse. This structure facilitates better oil flow out of the protective cover 1, making recovery easier. One end of the recovery pneumatic quick connector 52 is connected to the cavity 12, and the other end is connected to the external oil collection tank 51. The oil collection tank 51 is used to collect oil dripping into the protective cover 1. The recovery pneumatic quick connector 52 has a third external thread that mates with the third internal thread of the oil collection port 14. The recovery pneumatic quick connector 52 is connected to the protective cover 1 via the thread. After the thread of the recovery pneumatic quick connector 52 is tightened, it is slightly lower than the inside of the protective cover 1, facilitating oil recovery.

[0042] This utility model discloses a copper pipe surface oil recovery device. By setting an oil removal ring pipe 31, the outer surface of the copper pipe 4 contacts the inner wall of the oil removal ring pipe 31, preventing excessive oil residue on the outer surface of the copper pipe 4. An air jet nozzle 32 blows air onto the surface of the copper pipe 4, sweeping away the oil and preventing excessive oil residue on the outer surface of the copper pipe 4. This reduces the formation of oil droplets after the copper pipe 4 passes through the outlet 13, which fall onto the ground and material basket, reducing environmental pollution and adverse effects on the health of operators. The oil removal ring pipe 31 is equipped with a contact section 311, an oil guiding section 312, and a brush 313, making it easier to remove excess oil from the surface of the copper pipe 4. The protective cover 1 includes a guide nozzle 15 and a fastening ring 16, which can be used with copper pipes 4 of different outer diameters, expanding its applicability. The nozzle 15 has a frustum groove 152, which has a guiding function, facilitating the passage of the copper pipe through the protective cover 1. The guide nozzle 15 is made of graphite, which will not scratch the copper tube 4 when it comes into contact with it, and has good wear resistance.

[0043] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific implementation method of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, and improvements made within the scope of the spirit of this utility model should be included within the protection scope of this utility model.
