Description

Technical Field

[0001] This invention relates to the field of metal processing equipment technology, specifically a vertical aging furnace structure and heating system. Background Technology

[0002] A vertical aging furnace is a specialized industrial furnace used for aging heat treatment of metal components, particularly aluminum alloys and magnesium alloys, used in aerospace and high-end equipment parts. Its core process involves precisely controlling the heating temperature and holding time to induce the precipitation of strengthening phases from the supersaturated solid solution within the workpiece, thereby significantly improving the material's strength, hardness, and dimensional stability. A vertical structure typically refers to a furnace with the furnace body arranged vertically. Workpieces are fed into or removed from the heating chamber via a lifting mechanism. It is suitable for long shafts, cylindrical parts, or parts requiring vertical suspension, offering advantages such as small footprint, good furnace temperature uniformity, and minimal workpiece thermal deformation. In aerospace, rail transportation, and other fields, vertical aging furnaces are indispensable heat treatment equipment for controlling the performance of critical components.

[0003] Chinese patent application number CN202322128501.5, published on May 7, 2024, discloses a solution aging furnace for castings, relating to the field of casting processing. The furnace includes a base, a bottom roller, a water tank at the top of the roller, six sets of support columns at the top of the base, an aging furnace at the top of the support columns, a fan on the inner wall of the front of the aging furnace, a blower on one side of the aging furnace, a furnace cover on both sides of the top of the aging furnace, a material frame at the top of the aging furnace, a casting on the top of the material frame, a hook at the top of the material frame, and an air outlet on one side of the aging furnace. When aging castings, the fan ensures uniform temperature distribution inside the furnace, preventing some parts of the casting from being fully aged while others are under-aged, thus improving casting quality. The blower and air outlet allow impurities inside the furnace to be blown out through the air outlet before aging treatment, preventing impurities from adhering to the casting surface during the aging process, further improving casting quality.

[0004] The above invention has the following shortcomings in its structure: Existing vertical aging furnaces have significant deficiencies in the safety protection of their lifting mechanisms. Their lifting systems generally lack a purely mechanical anti-fall locking and controlled descent mechanism that can be triggered immediately upon main drive failure, completely independent of electricity. Current technologies mostly rely on electric brakes or simple mechanical stops. If the control system malfunctions, the electric brakes may fail to respond in time, causing the lifting platform carrying valuable workpieces to fall at high speed. This can not only cause severe impact damage to the workpieces but also potentially lead to major equipment accidents. More importantly, existing devices lack the function of achieving smooth, adjustable, and safe reset after a fall, making post-failure maintenance and reset operations both dangerous and inefficient, failing to meet the stringent requirements of high-end heat treatment equipment for safety redundancy and safe post-failure handling.

[0005] Existing vertical aging furnaces have inherent safety defects in personnel protection in hazardous areas. The opening and closing of their safety doors typically rely on independent cylinders and motors, interlocked with the lifting action via sensor signals and controller logic. This is an indirect and vulnerable electrical control and execution mode. If a sensor malfunctions, the signal is interrupted, or the program malfunctions, the interlock fails, potentially leading to the safety door not closing when the elevator enters the high-temperature furnace body, or the door being accidentally opened during heat treatment, posing a serious risk of personnel injury. Current technology lacks a purely mechanical, rigidly synchronized, forced isolation scheme for the lifting action. It cannot fundamentally ensure absolute safety by guaranteeing that the door must close during ascent and open only during descent, thus failing to guarantee the reliability of protection and the synchronization of process actions. Summary of the Invention

[0006] The purpose of this invention is to provide a vertical aging furnace structure and heating system to solve the problems mentioned in the background art.

[0007] To achieve this objective, the present invention adopts the following technical solution: A vertical aging furnace structure and heating system are provided, including a foundation, a processing mechanism, a safety mechanism, and an insurance mechanism; The processing mechanism includes a main body assembly, a lifting assembly, a heating assembly, and several circulation assemblies. The main body assembly and the lifting assembly are both located on top of the foundation, and the heating assembly and each circulation assembly are located on the main body assembly. The safety mechanism includes four drive components, four opening and closing components, and four safety doors. Each drive component is mounted on the lifting component, the four opening and closing components are mounted on the four drive components, and the four safety doors are mounted on the four opening and closing components. The insurance mechanism includes a sliding component, a limiting component, and a top rod. The sliding component is located on top of the foundation, the limiting component is located on the sliding component, and the top rod is located on the limiting component.

[0008] Furthermore, the main component includes two mounting brackets and a heating chamber. Each mounting bracket is fixedly installed on top of the foundation, and the heating chamber is fixedly installed on top of the two mounting brackets.

[0009] Furthermore, the lifting assembly includes a mounting slot, a lifting platform, and a receiving platform. The mounting slot is located at the top of the foundation, the lifting platform is fixedly installed inside the mounting slot, and the receiving platform is fixedly installed on top of the lifting platform.

[0010] Furthermore, the heating assembly includes a jacket, several connecting slots, several ignition nozzles, a delivery pipe, and an exhaust pipe. The jacket is fixedly installed inside the heating chamber, each connecting slot is opened on the outer wall of the heating chamber, several ignition nozzles are fixedly installed inside the several connecting slots, the delivery pipe is fixedly installed on the side end of the several ignition nozzles, and the exhaust pipe is fixedly installed on the top of the heating chamber.

[0011] Furthermore, each circulation component includes a first motor and circulation fan blades. The first motor is fixedly mounted on the top of the heating chamber, and the circulation fan blades are fixedly mounted on the output end of the first motor.

[0012] Furthermore, each drive component includes a lifting groove, a lifting block, and a connecting rod. The lifting groove is formed on the outer wall of one of the mounting brackets, the lifting block is slidably connected inside the lifting groove, and the connecting rod is fixedly installed at the bottom of the receiving platform, with the bottom of the connecting rod being fixedly connected to the connecting end of the lifting block.

[0013] Furthermore, each opening and closing assembly includes two mounting seats and a first lead screw. Each mounting seat is fixedly mounted on the outer wall of one of the mounting brackets. The first lead screw is rotatably connected between the two mounting seats. The interior of one of the lifting blocks is threadedly connected to the outer wall of the first lead screw. The two connecting ends of one of the safety doors are fixedly connected to the two ends of the first lead screw, respectively.

[0014] Furthermore, the sliding assembly includes a preset groove, a sliding frame, a second lead screw, a second motor, and a sliding block. The preset groove is opened at the top of the foundation, the sliding frame is fixedly installed inside the preset groove, the second lead screw is rotatably connected inside the sliding frame, the second motor is fixedly installed on the outer wall of the sliding frame, and the sliding block is threadedly connected to the outer wall of the second lead screw.

[0015] Furthermore, the limiting assembly includes a pedal, a sleeve, two sliding rods, two springs, a top pin, and a mounting rod. The sleeve is fixedly installed on the top of the sliding block, each sliding rod is fixedly installed inside the sleeve, the top pin is slidably connected to the outer wall of the two sliding rods, each spring is fixedly installed between the top pin and the sleeve, the pedal is fixedly installed on the outer wall of the top pin, and the mounting rod is fixedly installed on the elevator. The connecting end of the top rod is fixedly connected to the outer wall of the mounting rod.

[0016] Furthermore, the conveying pipeline is connected to an external gas supply device to deliver combustible gas to each ignition nozzle at a set flow rate. Each ignition nozzle is equipped with a spark plug. Upon receiving an ignition signal from an external controller, the spark plug is energized to generate an electric spark, igniting the delivered combustible gas and forming a stable jet flame that directly sprays the flame onto the outer wall of the jacket, rapidly and uniformly heating the jacket. Subsequently, the jacket indirectly heats the material inside the heating chamber through thermal radiation, avoiding direct flame contact with the material. For example, the heating system is set to a heating temperature of 170℃–190℃ for aluminum alloy materials, with a holding time of 2–4 hours. A temperature detection device is installed inside the heating chamber. The system is designed to monitor the temperature inside the heating chamber in real time and feed the temperature signal back to the external gas supply device and ignition nozzle. Based on the comparison between the feedback signal and the preset target temperature, the control system adjusts the combustible gas supply of the external gas supply device and controls the ignition state and flame size of the ignition nozzle to achieve precise temperature control. The exhaust pipe is used to discharge the exhaust gas and excess heat generated by combustion from the heating chamber to maintain stable pressure and atmosphere inside the chamber. The first motor drives the circulating fan blades fixedly connected to its output end to rotate, forcibly driving airflow inside the heating chamber, so that the heat generated by the jacket radiation can be quickly and evenly diffused throughout the chamber space, eliminating local overheated or undercooled areas and ensuring that all parts of the material are heated uniformly.

[0017] The beneficial effects of this invention are: 1. The safety mechanism of this equipment is designed with a dual-redundancy, mechanically triggered fall prevention and slow descent system. Its core lies in the fact that when the elevator is normally ascending, the top rod automatically avoids the pin of the limit component through its inclined surface design; in the event of an unexpected elevator failure, the scissor structure's external support will cause the top rod to move in the opposite direction. At this time, the plane of the top rod will be immediately and rigidly locked by the plane of the pin, achieving instantaneous mechanical self-locking and preventing the equipment from falling. For normal descent or emergency release, the operator can directly unlock the mechanism by stepping on the pedal, or gradually release the locked state by fine-tuning the position of the sliding block using the second motor. This design not only provides hard stop protection at the moment of failure, avoiding impact damage to the load-bearing structure, but also achieves controlled and smooth slow descent when necessary. It is a highly reliable mechanical safety solution integrating automatic protection, manual intervention, and controlled release. 2. The system's safety mechanism creates an active safety barrier that requires no manual intervention. At its core, the vertical displacement of the elevator is rigidly converted into the rotational opening and closing of the safety door via a threaded transmission. When the elevator rises to deliver materials into the heating chamber, the mechanical linkage forcibly closes the safety door, physically isolating the high-temperature, high-pressure heating zone from the personnel activity area; when the elevator descends to its reset position, the safety door automatically opens. This rigid logic of closing the door upon rising and opening it upon descending completely eliminates the possibility of personnel accidentally entering the danger zone during elevator operation or high-temperature work, internalizing safety procedures as an inherent attribute of the equipment, and achieving zero-delay, zero-error active protection. 3. The system's safety mechanism demonstrates exceptional energy efficiency in its power utilization. The power driving the safety door's opening and closing is entirely recovered from the lifting mechanism's own lifting power, achieved through a screw and nut assembly, eliminating the need for a separate motor or cylinder for the safety door. This integrated design, with one power source and multiple functions, eliminates the need for a separate power and control system for safety features. This not only significantly reduces manufacturing costs, energy consumption, and maintenance complexity but also ensures high reliability due to its purely mechanical structure, guaranteeing that safety protection will not fail under any operating conditions due to power outages or signal failures.

[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the invention. To better illustrate the embodiments of the invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions.

[0022] Example 1: The present invention provides a technical solution, such as... Figures 1-9 As shown, a vertical aging furnace structure and heating system includes a foundation 1, as well as a processing mechanism, a safety mechanism and an insurance mechanism; The processing mechanism includes a main body assembly, a lifting assembly, a heating assembly, and several circulation assemblies. The main body assembly and the lifting assembly are both located on top of the foundation 1, and the heating assembly and each circulation assembly are located on the main body assembly. The safety mechanism includes four drive components, four opening and closing components, and four safety doors 11. Each drive component is mounted on the lifting component, the four opening and closing components are mounted on the four drive components, and the four safety doors 11 are mounted on the four opening and closing components. The safety mechanism includes a sliding component, a limiting component, and a top rod 30. The sliding component is located on top of the foundation 1, the limiting component is located on the sliding component, and the top rod 30 is located on the limiting component.

[0023] like Figure 1As shown, the main component includes two mounting brackets 2 and a heating chamber 3. Each mounting bracket 2 is fixedly installed on top of the foundation 1, and the heating chamber 3 is fixedly installed on top of the two mounting brackets 2. The two mounting brackets 2 are made of high-strength steel and are firmly fixed to the foundation 1 with anchor bolts, forming a symmetrical load-bearing structure and providing a stable and level mounting foundation for the heating chamber 3. The heating chamber 3 is integrally welded or bolted to the top of the mounting brackets 2, forming a sealed rectangular heating space inside. This space is used to accommodate materials to be aged, such as aluminum alloy profiles or castings. Meanwhile, the bottom of the heating chamber 3 is designed with an open opening to allow the lifting assembly to feed or remove materials.

[0024] like Figures 1-2 As shown, the lifting assembly includes a mounting slot 4, a lifting platform 5, and a receiving platform 31. The mounting slot 4 is located at the top of the foundation 1. The lifting platform 5 is fixedly installed inside the mounting slot 4, and the receiving platform 31 is fixedly installed on top of the lifting platform 5. The mounting slot 4 is a precast, sunken rectangular pit in the concrete of the foundation 1, with its depth and dimensions matching the base of the lifting platform 5. This allows the lifting platform 5 to be fully embedded into the foundation 1, thereby reducing the overall height of the equipment and enhancing the anti-overturning stability of the lifting platform 5 during operation. The lifting platform 5 adopts a scissor-type hydraulic lifting structure, which includes cross linkages and drive cylinders, providing sufficient lifting force and smooth lifting speed. The receiving platform 31 is fixedly installed at the top of the uppermost scissor arm of the lifting platform 5. The platform surface is provided with anti-slip textures or positioning slots for placing material pallets. Before heat treatment, the operator places the material on the receiving platform 31, then starts the elevator 5. The elevator 5 pushes the receiving platform 31 vertically upward, accurately pushing the material into the heating chamber 3. After the aging treatment is completed, the elevator 5 reverses its direction, causing the receiving platform 31 to descend smoothly, removing the material from the heating chamber 3 to ground level for easy unloading. The lifting speed of the receiving platform 31 can be steplessly adjusted via a hydraulic valve according to process requirements. Simultaneously, the direction of movement of the receiving platform 31 is directly transmitted to the safety mechanism via the connecting rod 8, forming a mechanical linkage that eliminates the need for additional sensors.

[0025] like Figures 1-6As shown, the heating assembly includes a jacket 12, several connecting slots 13, several ignition nozzles 14, a conveying pipe 15, and an exhaust pipe 16. The jacket 12 is fixedly installed inside the heating chamber 3. Each connecting slot 13 is formed on the outer wall of the heating chamber 3. The several ignition nozzles 14 are respectively fixedly installed inside the several connecting slots 13. The conveying pipe 15 is fixedly installed on the side end of the several ignition nozzles 14. The exhaust pipe 16 is fixedly installed on the top of the heating chamber 3. The conveying pipe 15 is connected to an external gas supply device to deliver combustible gas to each ignition nozzle 14. Each ignition nozzle 14 is equipped with a spark plug. When the spark plug is energized, it generates an electric spark, igniting the delivered combustible gas to form a stable flame. The ignition nozzles 14 directly spray flames onto the jacket 12 through the connecting slots 13 on the outer wall of the heating chamber 3, so that the jacket 12 is rapidly and evenly heated. Subsequently, the jacket 12 indirectly heats the material inside the heating chamber 3 through thermal radiation. Meanwhile, the exhaust gas and excess heat generated by combustion are discharged through the exhaust pipe 16 at the top of the heating chamber 3, maintaining stable pressure and atmosphere inside the chamber. A temperature detection device installed inside the heating chamber 3 monitors the temperature in real time and feeds the signal back to the control system of the external gas supply device and ignition nozzle 14 to adjust the gas supply and ignition status, thereby achieving precise temperature control.

[0026] like Figures 1-7 As shown, each circulation component includes a first motor 17 and a circulation fan blade 18. The first motor 17 is fixedly installed on the top of the heating chamber 3, and the circulation fan blade 18 is fixedly installed on the output end of the first motor 17. After the first motor 17 is powered on, it drives the circulation fan blade 18 to rotate, which forces the air to flow inside the heating chamber 3, so that the heat generated by the heating component can be quickly and evenly diffused to the entire chamber space, avoiding local overheating or undercooling, thereby ensuring that all parts of the material are heated evenly, and improving the uniformity and efficiency of the aging process.

[0027] like Figures 1-4 As shown, each drive assembly includes a lifting groove 6, a lifting block 7, and a connecting rod 8. The lifting groove 6 is formed on the outer wall of one of the mounting brackets 2. The lifting block 7 is slidably connected inside the lifting groove 6. The connecting rod 8 is fixedly installed at the bottom of the receiving platform 31, and its bottom is fixedly connected to the connecting end of the lifting block 7. When the receiving platform 31 rises or falls under the drive of the elevator 5, the connecting rod 8 fixed at its bottom moves synchronously. The lower end of the connecting rod 8 is fixedly connected to the lifting block 7, thus forcing the lifting block 7 to slide vertically along the lifting groove 6 on the outer wall of the mounting bracket 2. When the elevator 5 rises and pushes the material into the heating chamber 3, the lifting block 7 slides upward; when the elevator 5 falls, the lifting block 7 slides downward. This sliding motion provides the driving force for the opening and closing assembly, thereby realizing the linkage between the safety door 11 and the lifting action.

[0028] like Figures 1-5As shown, each opening and closing assembly includes two mounting seats 9 and a first lead screw 10. Each mounting seat 9 is fixedly mounted on the outer wall of one of the mounting brackets 2. The first lead screw 10 is rotatably connected between the two mounting seats 9. The interior of one of the lifting blocks 7 is threadedly connected to the outer wall of the first lead screw 10. The two connecting ends of one of the safety doors 11 are fixedly connected to the two ends of the first lead screw 10, respectively. When the lifting block 7 slides along the lifting groove 6, due to the threaded engagement between its interior and the first lead screw 10, the linear movement of the lifting block 7 forces the first lead screw 10 to rotate between the two mounting seats 9. The two ends of the first lead screw 10 are fixedly connected to the two connecting ends of the safety door 11, so the rotation of the lead screw directly drives the safety door 11 to swing or rotate around its axis. The specific linkage is as follows: When the elevator 5 rises, the lifting block 7 moves upward, causing the first lead screw 10 to rotate in the forward direction, driving the safety door 11 to close, thereby sealing off the lifting area at the bottom and isolating personnel outside the lifting area to prevent them from accidentally standing below the elevator 5; when the elevator 5 descends, the lifting block 7 moves downward, causing the first lead screw 10 to rotate in the reverse direction, driving the safety door 11 to open, exposing the lifting area for easy access to materials. This achieves a safety interlock of closing the door when rising and opening the door when descending, effectively preventing personnel from accidentally entering the dangerous area during the operation of the elevator 5, while also providing double protection in conjunction with the safety mechanism in the event of an accidental loss of power in the elevator 5.

[0029] like Figures 1-8 As shown, the sliding assembly includes a preset groove 19, a sliding frame 20, a second lead screw 21, a second motor 23, and a sliding block 24. The preset groove 19 is located at the top of the foundation 1. The sliding frame 20 is fixedly installed inside the preset groove 19. The second lead screw 21 is rotatably connected inside the sliding frame 20. The second motor 23 is fixedly installed on the outer wall of the sliding frame 20. The sliding block 24 is threadedly connected to the outer wall of the second lead screw 21. After the second motor 23 is started, it drives the second lead screw 21 to rotate inside the sliding frame 20. The sliding block 24, through its threaded engagement with the second lead screw 21, converts the rotational motion into linear movement along the direction of the sliding frame 20. The sliding frame 20 is fixed within the preset groove 19 of the foundation 1, so the sliding block 24 can move precisely within the range defined by the preset groove 19. By controlling the direction and amount of rotation of the second motor 23, the position of the sliding block 24 can be adjusted, thereby moving the limiting assembly above it, preparing to release the lock on the top rod 30 when needed.

[0030] like Figures 1-9As shown, the limiting assembly includes a pedal 22, a sleeve 25, two sliding rods 26, two springs 27, a top pin 28, and a mounting rod 29. The sleeve 25 is fixedly installed on the top of the sliding block 24. Each sliding rod 26 is fixedly installed inside the sleeve 25. The top pin 28 is slidably connected to the outer wall of the two sliding rods 26. Each spring 27 is fixedly installed between the top pin 28 and the sleeve 25. The pedal 22 is fixedly installed on the outer wall of the top pin 28. The mounting rod 29 is fixedly installed on the elevator 5. The connecting end of the top rod 30 is fixedly connected to the outer wall of the mounting rod 29. The mounting rod 29 is fixed to the sliding end of the scissor lift inside the elevator 5. When the elevator 5 rises, the scissor lift retracts, and the mounting rod 29 drives the top rod 30 to move synchronously. The end of the top rod 30 has an arc surface, and the outer wall of the top pin 28 also has an arc surface and a flat surface. During retraction, the arc surface of the top rod 30 contacts the arc surface of the top pin 28. Guided by the inclined plane, the top pin 28 is forced to slide downwards along the two sliding rods 26, overcoming the force of the spring 27, without obstructing the movement of the top rod 30. When the elevator 5 reaches its designated position, the top rod 30 passes over the arc surface area of ​​the top pin 28 and moves to the flat side of the top pin 28. At this point, the spring 27 pushes the top pin 28 back to its original position, and the flat surface of the top pin 28 abuts against the flat surface of the top rod 30. If the elevator 5 unexpectedly malfunctions and descends, the scissor lift will extend outwards, causing the top rod 30 to move in the opposite direction. However, the movement of the top rod 30 is blocked by the flat surface of the top pin 28, preventing further movement and thus locking the elevator 5 to prevent accidental fall. When normal descent is required, simply step on the pedal 22 before the elevator 5 descends. The pedal 22 causes the top pin 28 to slide downwards along the two sliding rods 26, releasing the flat surface of the top pin 28 from the restriction on the top rod 30, thus unlocking the elevator 5 and allowing it to descend normally. When the elevator 5 needs to return to its safe position and loses power, the second motor 23 is started to drive the second lead screw 21 to rotate, which drives the sliding block 24 and the limiting components above it to move slowly towards the scissor frame of the elevator 5. This causes the top pin 28 to gradually increase its restriction on the top rod 30, thereby gradually releasing the displacement restriction and allowing the elevator 5 to fall smoothly to the bottom under control.

[0031] like Figures 1-7As shown, the conveying pipe 15 is connected to an external gas supply device to deliver combustible gas to each ignition nozzle 14 at a set flow rate. Each ignition nozzle 14 is equipped with a spark plug. Upon receiving an ignition signal from an external controller, the spark plug is energized to generate an electric spark, igniting the delivered combustible gas and forming a stable jet flame that directly sprays the flame onto the outer wall of the jacket 12, rapidly and uniformly heating the jacket 12. Subsequently, the jacket 12 indirectly heats the material inside the heating chamber 3 through thermal radiation, avoiding direct contact between the flame and the material. For example, the heating system is set to a heating temperature of 170℃–190℃ for the aluminum alloy material, and the holding time is set to 2–4 hours. A temperature detection device is installed inside the heating chamber 3. The control system is used to monitor the temperature inside the heating chamber 3 in real time and feed the temperature signal back to the external gas supply device and the ignition nozzle 14. The control system adjusts the combustible gas supply of the external gas supply device and controls the ignition state and flame size of the ignition nozzle 14 according to the comparison result of the feedback signal and the preset target temperature, so as to achieve precise temperature control. The exhaust pipe 16 is used to discharge the exhaust gas and excess heat generated by combustion from the heating chamber 3 to maintain the pressure and atmosphere stability inside the chamber. The first motor 17 drives the circulating fan blade 18 fixedly connected to its output end to rotate, which forces the air to flow inside the heating chamber 3, so that the heat radiated by the jacket 12 can be quickly and evenly diffused to the entire chamber space, eliminating local overheated or undercooled areas and ensuring that all parts of the material are heated evenly.

[0032] The specific working process of this invention is as follows: First, the material to be processed is placed on the receiving platform 31. Then, the elevator 5 is started, and the elevator 5 drives the receiving platform 31 to rise vertically, pushing the material upward into the heating chamber 3. During this process, the connecting rod 8 fixed to the bottom of the receiving platform 31 rises synchronously, driving the lifting block 7 to slide upward along the lifting groove 6 on the outer wall of the mounting bracket 2. The lifting block 7 drives the first lead screw 10 to rotate forward between the two mounting seats 9 through threaded engagement, thereby driving the safety door 11 to close and sealing the lifting area to prevent personnel from accidentally entering. At the same time, the mounting rod 29 fixed to the sliding end of the scissor frame inside the elevator 5 moves as the elevator 5 rises, driving the top rod 30 to move synchronously. The arc surface at the end of the top rod 30 first contacts the arc surface of the top pin 28. Through the inclined guide, the top pin 28 is forced to overcome the force of the spring 27 and slide downward along the two sliding rods 26. When the top rod 30 passes the arc surface area of ​​the top pin 28, the spring 27 pushes the top pin 28 to reset, so that the plane of the top pin 28 abuts against the plane of the top rod 30, thereby locking and protecting the elevator 5. After the material enters the heating chamber 3, the external gas supply device delivers combustible gas to each ignition nozzle 14 via the delivery pipe 15. The spark plug, when energized, generates an electric spark, igniting the delivered combustible gas to form a stable flame. The ignition nozzle 14 directly sprays flames into the jacket 12 through the connecting groove 13 on the outer wall of the heating chamber 3, rapidly and evenly heating the jacket 12. Subsequently, the jacket 12 indirectly heats the material inside the heating chamber 3 through thermal radiation. Simultaneously, the first motor 17 drives the circulating fan blades 18 to rotate, forcibly driving airflow inside the heating chamber 3 to ensure even heat diffusion. The exhaust gas generated during combustion is discharged through the exhaust pipe 16. After the aging treatment is completed, when lowering is required, the pedal 22 is first pressed. The pedal 22 drives the top pin 28 to slide downwards along the two sliding rods 26, making the top pin 28 flat. Release the top rod 30 from its restraints and unlock it; or if the elevator 5 loses power, start the second motor 23 to drive the second lead screw 21 to rotate, causing the sliding block 24 and its upper sleeve 25, top pin 28, etc. to move towards the outer support of the scissor lift frame of the elevator 5, gradually releasing the displacement restriction on the top rod 30; after the safety is released, the elevator 5 drives the receiving platform 31 to descend, removing the material from the heating chamber 3.

10. A heating system for a vertical aging furnace structure according to any one of claims 1-9, characterized in that, The conveying pipe (15) is connected to an external gas conveying device to deliver combustible gas to each ignition nozzle (14) at a set flow rate. Each ignition nozzle (14) is equipped with a spark plug. After receiving an ignition signal from an external controller, the spark plug is energized to generate an electric spark, igniting the delivered combustible gas and forming a stable jet flame that directly sprays the flame onto the outer wall of the jacket (12), so that the jacket (12) is heated rapidly and evenly. Subsequently, the jacket (12) indirectly heats the material inside the heating chamber (3) by thermal radiation, avoiding direct contact between the flame and the material. For example, the heating system sets the heating temperature of the aluminum alloy material to 170℃–190℃ and the heat preservation time to 2–4 hours. The heating chamber (3) is equipped with a temperature detection device for... The control system monitors the temperature inside the heating chamber (3) in real time and feeds the temperature signal back to the external gas supply device and the ignition nozzle (14). The control system adjusts the combustible gas supply of the external gas supply device and controls the ignition state and flame size of the ignition nozzle (14) according to the comparison result between the feedback signal and the preset target temperature, so as to achieve precise temperature control. The exhaust pipe (16) is used to discharge the exhaust gas and excess heat generated by combustion from the heating chamber (3) to maintain the pressure and atmosphere stability inside the chamber. The first motor (17) drives the circulating fan blade (18) fixedly connected to its output end to rotate, which forces the air to flow inside the heating chamber (3), so that the heat radiated by the jacket (12) can be quickly and evenly diffused to the entire chamber space, eliminating local overheated or overcooled areas and ensuring that all parts of the material are heated evenly.
