Description

Technical Field

[0001] This application relates to the field of automotive condenser fin processing technology, and in particular to lead coating equipment for automotive condenser fins. Background Technology

[0002] The production of automotive condenser fins involves multiple processes, including stamping, degreasing, lead coating, and cooling. Currently, the industry commonly uses gas-fired degreasing furnaces for degreasing. However, with increasingly stringent environmental regulations, achieving efficient degreasing while reducing emissions has become a key technical challenge.

[0003] In existing technologies, conventional degreasing methods include: gas-fired direct-heating degreasing furnaces, which remove grease from the surface of workpieces through high-temperature combustion, but the exhaust gas contains unburned organic matter; electric-heating degreasing furnaces, which reduce exhaust emissions but have extremely high energy consumption; and external combustion furnaces for separate exhaust gas treatment, but without heat recovery and utilization. Among these, gas-fired direct-heating degreasing furnaces have lower costs but poor environmental performance; electric-heating degreasing furnaces are environmentally friendly but have high operating costs; and external combustion furnaces for separate exhaust gas treatment increase equipment complexity and result in serious heat waste, while lacking an integrated exhaust gas treatment and heat recovery system. Summary of the Invention

[0004] The purpose of this application is to provide lead coating equipment for automotive condenser fins.

[0005] Firstly, the lead-coating equipment for automotive condenser fins provided in this application adopts the following technical solution: An automotive condenser fin lead coating equipment includes a base, a stamping machine on one side of the top of the base, a degreasing furnace on one side of the stamping machine, a lead coating box on the side of the degreasing furnace away from the stamping machine, a combustion furnace on one side of the degreasing furnace, an exhaust pipe connected to the top of the degreasing furnace, one end of the exhaust pipe being connected to the combustion furnace, a heat exchanger inside the combustion furnace, the heat exchanger end being connected to the degreasing furnace, and a circulation pipe on one side of the degreasing furnace, the two ends of the circulation pipe being connected to the outer walls of the two sides of the degreasing furnace respectively.

[0006] By adopting the above technical solution, a stamping machine, a degreasing furnace, and a lead-based coating box are sequentially installed on the top of the equipment base to form a continuous production line. A combustion furnace is configured on one side of the degreasing furnace, and the two are connected by an exhaust gas pipe. This allows the exhaust gas generated after the degreasing of the automotive condenser fins in the degreasing furnace to enter the combustion furnace. A heat exchanger is installed inside the combustion furnace so that its heat exchange end is connected to the furnace cavity of the degreasing furnace. The heat generated by the combustion exhaust gas in the combustion furnace enters the degreasing furnace through the heat exchanger for reuse. A circulation pipe runs through both sides of the degreasing furnace to achieve airflow circulation.

[0007] The degreasing furnace is equipped with burners on both sides of the bottom. Multiple sets of burners are arranged at equal intervals. A refractory baffle is provided at the flame nozzle of the burner. A heat-conducting pipe is connected to one side of the refractory baffle. The heat-conducting pipe is connected to one end of a heat exchanger. A heat insulation pad is fixedly connected to the inner wall of the degreasing furnace.

[0008] By adopting the above technical solution, the burner uses gas heating for combustion. The refractory baffle absorbs the flame impact of the burner and diffuses the heat energy. Its high-temperature area is conducted to the heat pipe. At the same time, the heat exchanger can also conduct the heat generated by the combustion furnace to the cavity of the degreasing furnace and the location of the heat pipe. The circulating air generated by the circulation pipe blows the high-temperature gas after combustion onto the fin surface. Uniform heating is achieved through forced convection. Heat transfer is achieved through indirect heating combined with forced convection, thereby performing high-temperature degreasing treatment on the fins. At the same time, it can protect the surface quality of the fins and avoid local overheating.

[0009] A central rod is connected to the center of the top inner wall of the degreasing furnace via a bearing. An auxiliary frame is connected to the top outer wall of the central rod via a bearing. The top of the auxiliary frame is connected to the outer wall of the degreasing furnace. A placement frame is fixedly connected to the middle outer wall of the central rod. Two sets of placement frames are arranged vertically, and a partition plate is provided between the two sets of placement frames. The partition plate is fixedly connected to the central rod and is inclined. Through holes are arranged on the surface of the placement frame.

[0010] By adopting the above technical solution, the central rod is supported by double bearings through the top and auxiliary frame, thus forming a cantilever structure. Two sets of placement frames are distributed vertically along the central rod, and the condenser fins can be placed horizontally on the surface of the placement frames. After the condenser fins are heated, the grease falls off and can be discharged through the through holes. The partition plate acts as a separator, and the grease can be discharged into the grease collection tray through its edge, avoiding the top grease dripping onto the bottom fin surface and affecting the degreasing of the bottom fins. The central rod is driven to rotate axially by a servo motor, thereby driving the placement frame and the condenser fins on its top to rotate. The shearing force generated by the rotation can destroy the oil film adhesion, thereby shortening the degreasing time. At the same time, continuous rotation can eliminate airflow dead zones, so that all surfaces of the fins are heated evenly, significantly improving the degreasing uniformity, especially for parallel flow condensers with complex structures and tube-and-fin condensers with multi-layer louvered fins.

[0011] A servo motor is fixedly connected to the top outer wall of the degreasing furnace. The output end of the servo motor is connected to the central rod through a coupling. The servo motor drives the central rod to rotate, and the rotation of the central rod causes the placement frame to rotate synchronously.

[0012] By adopting the above technical solution, the servo motor serves as the power source for the central rod, thus playing a driving role.

[0013] A grease collection tray is fixedly connected to the center of the bottom of the degreasing furnace. The upper surface of the grease collection tray is conical. A drain port is provided on one side edge of the grease collection tray. An oil storage box is provided on one side of the bottom of the grease collection tray. The drain port is connected to the oil storage box. A scraper is fixedly connected to the bottom end of the central rod. The scraper abuts against the upper surface of the grease collection tray.

[0014] By adopting the above technical solution, the upper surface of the grease collection tray is designed with a conical inclination so that after the molten grease drips onto the tray surface, it automatically flows along the inclination to the bottom edge. Then, the central rod rotates, driving the placement frame to rotate, which in turn drives the scraper to rotate. The scraper rotates along the surface of the grease collection tray, thus pushing the grease on the surface to rotate and enter the drain port. At the same time, it avoids the grease adhering to the surface of the grease collection tray. Then, it enters the oil storage box through the drain port for collection, thereby realizing the collection of grease for subsequent recycling.

[0015] A fixed frame is fixedly connected to one side of the inner wall of the degreasing furnace. A linkage rod is connected to the middle of the fixed frame through a bearing, and both ends of the linkage rod pass through both sides of the fixed frame. A bevel gear is fixedly connected to the bottom outer wall of the middle rod.

[0016] By adopting the above technical solution, the fixing frame serves to fix the linkage rod, which can rotate within the fixing frame. The rotation of the central rod drives the first bevel gear to rotate.

[0017] A second bevel gear is fixedly connected to one end of the linkage rod near the middle rod. The first bevel gear meshes with the second bevel gear, and an isolation box is fitted around the first and second bevel gears. The isolation box is connected to the middle rod through a bearing, and the linkage rod of the isolation box is connected to the other through a bearing.

[0018] By adopting the above technical solution, the No. 1 bevel gear drives the No. 2 bevel gear to rotate, thereby driving the linkage rod to achieve axial power transmission, and the isolation box can isolate oil stains from corrosion.

[0019] Both ends of the circulation pipe are equipped with filter screens. The end of the linkage rod away from the second bevel gear extends through the filter screen into the interior of one end of the circulation pipe. A spiral blade fan is fixedly connected to the end of the linkage rod. An auxiliary fan is provided in the middle of the circulation pipe.

[0020] By adopting the above technical solution, the first bevel gear drives the second bevel gear to rotate, which in turn drives the linkage rod to rotate. The rotation of the linkage rod can drive the spiral fan to rotate, thereby assisting the air intake of the circulation pipe, thus reducing the energy consumption of the auxiliary fan. The auxiliary fan can accelerate the air flow and circulation in the circulation pipe, and the filter screen plays a filtering role.

[0021] The combustion furnace is equipped with an exhaust gas burner in the middle, an exhaust pipe at the top, and an electric control valve at the end of the exhaust pipe. Both the degreasing furnace and the combustion furnace are equipped with online VOCs detectors.

[0022] By adopting the above technical solution, the VOCs-containing waste gas generated by the degreasing furnace enters the middle of the combustion furnace through the waste gas pipe. The waste gas burner completely oxidizes and decomposes it at high temperature, and the concentration is monitored in real time by the online VOCs detector.

[0023] The lead-based coating box is equipped with spray guns arranged at equal intervals around it, and an air cooler is installed on one side of the lead-based coating box.

[0024] By adopting the above technical solution, multiple spray guns are arranged in a ring at equal intervals to carry out three-dimensional spraying as the fins pass by, achieving full coverage of the fins. The sprayed fins are then shaped and cooled by an air cooler.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. After degreasing the automotive condenser fins in a degreasing furnace, the resulting exhaust gas can enter a combustion furnace. The combustion furnace is equipped with a heat exchanger, which connects to the furnace chamber of the degreasing furnace. The heat generated by the combustion of exhaust gas in the combustion furnace is then transferred to the degreasing furnace for reuse. A circulation pipe runs through both sides of the degreasing furnace to achieve airflow circulation. This ensures that the exhaust gas generated in the degreasing furnace is fully combusted in the combustion furnace and the heat is transferred to the degreasing furnace, improving the degreasing efficiency and allowing the exhaust gas to be safely discharged. 2. The servo motor drives the central rod to rotate axially, thereby rotating the placement rack and the condenser fins on top of it. The shearing force generated by the rotation can destroy the oil film adhesion, thereby shortening the degreasing time. At the same time, continuous rotation can eliminate airflow dead zones, so that all surfaces of the fins are heated evenly, significantly improving the degreasing uniformity, especially for parallel flow condensers with complex structures and tube-and-fin condensers with multi-layer louvered fins.

[0029] Example: Lead coating equipment for automotive condenser fins includes a base 1. A press 2 is mounted on one side of the top of the base 1. A degreasing furnace 3 is mounted on one side of the press 2. A lead coating box 4 is mounted on the side of the degreasing furnace 3 away from the press 2. A combustion furnace 5 is mounted on one side of the degreasing furnace 3. An exhaust pipe 6 is connected to the top of the degreasing furnace 3, and one end of the exhaust pipe 6 is connected to the combustion furnace 5. A heat exchanger 8 is installed inside the combustion furnace 5, and the heat exchange end of the heat exchanger 8 is connected to the degreasing furnace 3. A circulation pipe 9 is mounted on one side of the degreasing furnace 3, and both ends of the circulation pipe 9 are connected to the outer walls of the two sides of the degreasing furnace 3, respectively. The press 2 and the degreasing furnace 3 are sequentially mounted on the top of the base 1. Together with lead-coating spray box 4, a continuous production line is formed. A combustion furnace 5 is configured on one side of degreasing furnace 3, and the two are connected by exhaust gas pipe 6. This allows the exhaust gas generated after degreasing the automotive condenser fins in degreasing furnace 3 to enter combustion furnace 5. Combustion furnace 5 is equipped with heat exchanger 8, so that its heat exchange end is connected to the furnace cavity of degreasing furnace 3. The heat generated by the combustion of exhaust gas in combustion furnace 5 enters degreasing furnace 3 through heat exchanger 8 for reuse. Circulation pipe 9 runs through both sides of degreasing furnace 3 to realize airflow circulation. This allows the exhaust gas generated in degreasing furnace 3 to be fully combusted in combustion furnace 5 and heat exchanged to degreasing furnace 3, improving degreasing efficiency and ensuring safe discharge of exhaust gas.

[0030] Burners 10 are installed on both sides of the bottom of the degreasing furnace 3. Multiple sets of burners 10 are arranged at equal intervals. A refractory baffle 11 is installed at the flame nozzle of the burner 10. A heat-conducting pipe 12 is connected to one side of the refractory baffle 11. The heat-conducting pipe 12 is connected to one end of the heat exchanger 8. A heat insulation pad 13 is fixedly connected to the inner wall of the degreasing furnace 3. The burner 10 uses gas heating for combustion. The refractory baffle 11 absorbs the flame impact of the burner 10 and diffuses the heat energy. Its high-temperature area is conducted to the heat-conducting pipe 12. At the same time, the heat exchanger 8 can also conduct the heat generated by the combustion furnace 5 to the cavity of the degreasing furnace 3 and the heat-conducting pipe 12. The circulating air generated by the circulation pipe 9 blows the high-temperature gas after combustion onto the fin surface. Uniform heating is achieved through forced convection. Heat transfer is achieved through indirect heating combined with forced convection, thereby performing high-temperature degreasing treatment on the fins. At the same time, it can protect the surface quality of the fins and avoid local overheating.

[0031] A central rod 14 is connected to the center of the top inner wall of the degreasing furnace 3 via a bearing. An auxiliary frame 7 is connected to the top outer wall of the central rod 14 via a bearing. The top of the auxiliary frame 7 is connected to the outer wall of the degreasing furnace 3. A placement rack 15 is fixedly connected to the middle outer wall of the central rod 14. Two sets of placement racks 15 are arranged vertically, and a partition plate 16 is provided between the two sets of placement racks 15. The partition plate 16 is fixedly connected to the central rod 14 and is inclined. Through holes 17 are arranged on the surface of the placement rack 15. The central rod 14 is supported by double bearings through the top and the auxiliary frame 7, thus forming a cantilever structure. The two sets of placement racks 15 are distributed vertically along the central rod 14, and the condenser fins can be placed horizontally on the surface of the placement rack 15. After the condenser fins are heated, the grease that falls off can be discharged through the through hole 17. The partition plate 16 acts as a separator, and the grease can be discharged into the grease collection tray 19 through its edge, preventing the top grease from dripping onto the bottom fin surface and affecting the degreasing of the bottom fins. The servo motor 18 drives the central rod 14 to rotate axially, thereby driving the placement rack 15 and the condenser fins on top of it to rotate. The shearing force generated by the rotation can destroy the oil film adhesion, thereby shortening the degreasing time. At the same time, continuous rotation can eliminate airflow dead zones, so that all surfaces of the fins are heated evenly, significantly improving the degreasing uniformity, especially for parallel flow condensers with complex structures and tube-and-fin condensers with multi-layer louvered fins.

[0032] A servo motor 18 is fixedly connected to the top outer wall of the degreasing oven 3. The output end of the servo motor 18 is connected to the middle rod 14 through a coupling. The servo motor 18 drives the middle rod 14 to rotate. The rotation of the middle rod 14 drives the placement rack 15 to rotate synchronously. The servo motor 18 is the power source of the middle rod 14 and plays a driving role.

[0033] A grease collection tray 19 is fixedly connected to the center of the bottom of the degreasing furnace 3. The upper surface of the grease collection tray 19 is conical. A drain port 20 is provided on one side edge of the grease collection tray 19. An oil storage box 21 is provided on one side of the bottom of the grease collection tray 19. The drain port 20 is connected to the oil storage box 21. A scraper 35 is fixedly connected to the bottom end of the central rod 14. The scraper 35 abuts against the upper surface of the grease collection tray 19. The conical inclined design of the upper surface of the grease collection tray 19 allows molten grease to drip onto the tray surface and automatically flow along the inclined surface to the bottom edge. Then, the rotation of the central rod 14 drives the placement frame 15 to rotate, which in turn drives the scraper 35 to rotate. The scraper 35 rotates along the surface of the grease collection tray 19, thereby pushing the grease on its surface to rotate and enter the drain port 20. At the same time, it prevents grease from adhering to the surface of the grease collection tray 19. Then, the grease enters the oil storage box 21 through the drain port 20 for collection, thus realizing the collection of grease for subsequent recycling.

[0034] A fixed frame 22 is fixedly connected to the inner wall of one side of the degreasing furnace 3. A linkage rod 23 is connected to the middle of the fixed frame 22 through a bearing, and both ends of the linkage rod 23 pass through both sides of the fixed frame 22. A first bevel gear 24 is fixedly connected to the bottom outer wall of the middle rod 14. The fixed frame 22 serves to fix the linkage rod 23. The linkage rod 23 can rotate inside the fixed frame 22. The rotation of the middle rod 14 drives the first bevel gear 24 to rotate.

[0035] A second bevel gear 25 is fixedly connected to one end of the linkage rod 23 near the middle rod 14. The first bevel gear 24 meshes with the second bevel gear 25, and an isolation box 26 is sleeved on the outside of the first bevel gear 24 and the second bevel gear 25. The isolation box 26 is connected to the middle rod 14 through a bearing, and the linkage rod 23 is connected to the isolation box 26 through a bearing. The first bevel gear 24 drives the second bevel gear 25 to rotate, thereby driving the linkage rod 23 to achieve axial power transmission. The isolation box 26 can isolate oil stains from corrosion.

[0036] Both ends of the circulation pipe 9 are equipped with filter screens 27. The end of the linkage rod 23 away from the second bevel gear 25 extends through the filter screen 27 into the interior of one end of the circulation pipe 9, and the end of the linkage rod 23 is fixedly connected to a spiral fan 271. An auxiliary fan 28 is provided in the middle of the circulation pipe 9. The first bevel gear 24 drives the second bevel gear 25 to rotate, which in turn drives the linkage rod 23 to rotate. The rotation of the linkage rod 23 drives the spiral fan 271 to rotate, thereby assisting the air intake of the circulation pipe 9 and reducing the energy consumption of the auxiliary fan 28. The auxiliary fan 28 drives the air flow and circulation in the circulation pipe 9 to accelerate. The filter screen 27 plays a filtering role.

[0037] An exhaust gas burner 29 is installed in the middle of the combustion furnace 5, and an exhaust pipe 30 is installed at the top of the combustion furnace 5. An electric control valve 31 is installed at the end of the exhaust pipe 30. Both the degreasing furnace 3 and the combustion furnace 5 are equipped with online VOCs detectors 32. The VOCs-containing exhaust gas generated by the degreasing furnace 3 enters the middle of the combustion furnace 5 through the exhaust pipe 6. The exhaust gas burner 29 completely oxidizes and decomposes it at high temperature, and the online VOCs detector 32 monitors the concentration in real time.

[0038] The lead coating box 4 is equipped with spray guns 33, which are arranged in a equidistant ring. A fan cooler 34 is provided on one side of the lead coating box 4. The spray guns 33 are arranged in a equidistant ring to carry out three-dimensional spraying when the fins pass through, so as to achieve full coverage of the fins. The fan cooler 34 is used to cool and shape the sprayed fins.

[0039] The implementation principle of this application embodiment is as follows: First, the stamped fins are transferred to the double-layer placement rack 15 inside the degreasing furnace 3. The placement rack 15 is rotated by the central rod 14 driven by the servo motor 18. A gas supply pipe is provided on one side of the degreasing furnace 3 to provide oxygen for combustion. The burner 10 uses gas heating for combustion. The refractory baffle 11 absorbs the flame impact of the burner 10 and diffuses the heat energy. Its high-temperature area is conducted to the heat conduction pipe 12. At the same time, the heat exchanger 8 can also conduct the heat generated by the combustion furnace 5 to the cavity of the degreasing furnace 3 and the position of the heat conduction pipe 12. The circulating air generated by the circulation pipe 9 blows the high-temperature gas after combustion onto the surface of the fins, and uniformity is achieved through forced convection. Heating, achieved through indirect heating combined with forced convection, performs high-temperature degreasing on the fins, protecting the fin surface quality and preventing localized overheating. Grease detaches from the heated condenser fins and drains through the through-hole 17. The partition plate 16 acts as a separator, allowing grease to drain through its edge into the grease collection tray 19, preventing top grease from dripping onto the bottom fin surface and affecting degreasing. A servo motor 18 drives the central rod 14 to rotate axially, thereby rotating the placement rack 15 and the condenser fins on top of it. The shearing force generated by the rotation breaks down the oil film adhesion, shortening the degreasing time. Continuous rotation also eliminates... The design eliminates dead zones in the airflow, ensuring uniform heating across all surfaces of the fins and significantly improving degreasing uniformity. This is particularly beneficial for complex parallel-flow condensers and tube-and-fin condensers with multi-layered louvered fins. The tapered, inclined design of the upper surface of the grease collection tray 19 allows molten grease to drip onto the tray surface and automatically flow towards the bottom edge along the inclined surface. Then, the rotation of the central rod 14 drives the placement rack 15 to rotate, simultaneously rotating the scraper 35. The scraper 35 rotates along the surface of the grease collection tray 19, pushing the grease on its surface into the drain port 20. This prevents grease from adhering to the surface of the grease collection tray 19. Finally, the grease is collected in the oil storage box 21 through the drain port 20, thus achieving efficient degreasing. The collection of grease facilitates subsequent recycling. After degreasing the automotive condenser fins in the degreasing furnace 3, the resulting exhaust gas can enter the combustion furnace 5. The combustion furnace 5 is equipped with a heat exchanger 8, which connects its heat exchange end to the furnace cavity of the degreasing furnace 3. The heat generated by the combustion exhaust gas in the combustion furnace 5 enters the degreasing furnace 3 through the heat exchanger 8 for reuse. The circulation pipe 9 runs through both sides of the degreasing furnace 3 to achieve airflow circulation. After degreasing, the fins are transferred to the lead-based coating box 4 by a conveyor belt. The coating is applied in three dimensions by multiple equidistant ring-shaped spray guns 33 as the fins pass through, achieving full coverage of the fins. The coated fins are then shaped and cooled by an air cooler 34.

Identical components are represented by the same reference numerals.
