[0028] 1. An integrated heat exchange mechanism is provided. Through the cooperation of the impeller, square shaft, turbine, turntable, sleeve, partition, chuck, permanent magnet rotor, winding and coil, a two-way closed-loop positive feedback adjustment structure can be constructed. On the one hand, the energy in the heat treatment process can be recycled multiple times, which not only effectively improves the effective utilization rate of energy in the heat treatment process, but also can transform air thermal energy into the main power source, greatly reducing the energy consumption required in the heat treatment process of the gas cylinder, making the device more energy-saving and environmentally friendly, and can effectively reduce the interference and restriction of external energy on the heat treatment work, making the heat treatment work more continuous, stable and efficient, and making the heat treatment more flexible and convenient;

Through the cooperation of the wind wheel, shaft, gear plate, gear chain, bevel gear, circular plate, clamping column, box, piston plate, piston rod and linkage frame, a drive force grafting conversion structure can be constructed. On the one hand, it can greatly improve the effective utilization rate of the external driving force, and can provide more efficient and stable initial power support for the heat treatment work, so that the heat treatment work can be carried out more smoothly, which greatly improves the reliability of the heat treatment work. On the other hand, it can cooperate with the wind box, air supply pipe, check valve and three-way pipe to realize the cyclic superposition utilization of the initial power. While reducing the initial startup energy consumption, it can effectively improve the abundance and effectiveness of the initial energy, so that the heat treatment work can be carried out more smoothly;

[0033] In conjunction with the reversing box, negative pressure tube, air suction port, folding plate, through hole, guide ring, leakage pipe and gas valve, the vacuum treatment of the furnace body can be realized simultaneously without additional power source, and the energy in the heat treatment process can be further utilized to maintain the stability of the external environment of the gas cylinder, so that the internal vacuum degree of the furnace body can be dynamically controllable, which can further avoid the contact between the gas cylinder and the heat exchange medium during the heat treatment process, and can effectively reduce the pressure of the gas cylinder during the heat treatment process, so that the gas cylinder can be heated in an environment below the atmospheric pressure, so that its internal stress distribution is more uniform, and the deformation after quenching is greatly reduced.

[0034] To sum up, during the heat treatment process of gas cylinders, the device can perform multiple recycling of the energy in the heat treatment process, and can simultaneously convert the air thermal energy, greatly improving the effective utilization rate of energy, reducing energy consumption, and making the heat treatment environment of the gas cylinder controllable, realizing non-contact heat treatment, which not only makes the heat treatment work more balanced, effective and sufficient, but also effectively avoids the adverse effects on the performance of the gas cylinder caused by contact with the heat treatment medium, making the comprehensive mechanical properties of the gas cylinder after heat treatment more stable and reliable.

First, open the furnace cover 3, push the slide bar 224, drive the slide box 202 to slide, and push the partition 213 to one side of the furnace cover 3. After the slide bar 224 is pushed to the maximum limit, rotate the partition 213, remove the partition 213 from the shaft sleeve 212, align the gas cylinder bottle mouth with the support 223, and install the corresponding number of gas cylinder ferrules on each support 223 in turn, and then install the partition 213 again. At this time, the bottom plate 2232 will cooperate with the support 223 to lock the gas cylinder limit;

[0069] After the gas cylinder loading is completed, the furnace cover 3 is closed, and the air flow can be delivered to the air box 301 through the air supply pipe 302, so that the wind wheel 303 rotates under the drive of the air flow, and then under the transmission of the bevel gear 307, the shaft rod 304 will also drive the circular plate 308 to rotate accordingly, forcing the linkage frame 313 to drive the piston plate 311 to move back and forth inside the box body 310 through the piston rod 312 under the drag of the clamping column 309. At this time, under the flow restriction of the check valve 315, the air inside the reversing box 314 will be drawn into the box body 310 through the three-way pipe 316 connected thereto, and then pressed into the wind box 301 through another three-way pipe 316, forming a combined force with the air flow delivered at the air supply pipe 302, driving the wind wheel 303 to rotate faster;

[0070] After the air inside the reversing box 314 is extracted, the air pressure between the two folding plates 319 is reduced, and negative pressure is formed at the negative pressure pipe 317. Since the air inside the reversing box 314 on the other side of the two folding plates 319 has been extracted during the preparatory work, when the air pressure between the two folding plates 319 is higher than the air pressure on the other side of the two folding plates 319, the two folding plates 319 will remain stationary due to being restricted by the reversing box 314. As negative pressure is formed in the negative pressure pipe 317, the air inside the furnace body 2 will be forced to enter the guide ring 321 through the leakage pipe 322, and then enter the reversing box 314 through the negative pressure pipe 317, and finally be sent to the wind box 301 and discharged from the bottom opening of the wind box 301.

[0071] As the gas inside the furnace body 2 is extracted, the inside of the furnace body 2 will gradually tend to a vacuum state, and its internal air pressure will gradually decrease. Correspondingly, the air pressure between the two folding plates 319 inside the reversing box 314 will also decrease synchronously. When the air pressure between the two folding plates 319 is lower than the air pressure on the other side of the two folding plates 319, the two folding plates 319 will move toward each other under the action of negative pressure, causing the through hole 320 to be connected with the air suction port 318. At this time, the external air will enter the reversing box 314 through the air suction port 318 for pressure compensation, so that the vacuum degree inside the furnace body 2 always tends to the vacuum degree of the space outside the folding plate 319 inside the reversing box 314, while ensuring the normal flow of airflow, so that the wind wheel 303 can rotate continuously;

[0072] During the subsequent heat treatment of the gas cylinder, if the air pressure between the two folding plates 319 is higher than the air pressure on the other side of the two folding plates 319, since the two folding plates 319 have already shifted toward each other, that is, the two folding plates 319 are no longer limited by the reversing box 314, the two folding plates 319 will move away from each other under the action of the air pressure and return to the initial position, blocking the air inlet 318 again, and the air inside the furnace body 2 will be sucked out again, and the inside of the furnace body 2 will be vacuumed again, so that the inside of the furnace body 2 is maintained at a set vacuum degree, that is, the same vacuum degree as the space outside the folding plates 319 inside the reversing box 314 is maintained;

[0073] While the shaft 304 rotates, the impeller 205 also rotates synchronously driven by the toothed disc 305 and the toothed chain 306, and forces the turbine 210, the turntable 211, the sleeve 212 and the permanent magnet rotor 214 to rotate synchronously with the square shaft 206. During the rotation of the permanent magnet rotor 214, an induced current is generated inside the winding 215, and the induced current is transmitted to the coil 219 through the switch 4, so as to generate a magnetic field inside the coil 219, that is, inside the partition 217, forcing the gas cylinder body to generate eddy currents and quickly heat up, thereby electromagnetically heating the gas cylinder.

[0074] As the temperature of the gas cylinder rises, the temperature inside the furnace body 2 will rise accordingly, and the temperature inside the compartment 222 will also rise synchronously, causing the pressure inside the compartment 222 to increase, and the equilibrium state of the refrigerant inside the compartment 222 will be broken. The refrigerant inside the compartment 222 will be liquefied, and under the action of pressure, it will be pressed into the slide box 202 through the overflow pipe 208, so that the turbine 210 will rotate faster under its impact. In this process, the energy carried by the liquid refrigerant will be partially consumed, and the pressure will be reduced accordingly. Subsequently, the low-pressure liquid refrigerant will enter the connecting box 207, and under the guidance of the guide valve 221, it will enter the heat exchange tube 220 through the return pipe 209;

[0075] As the impeller 205 rotates, the refrigerant in the heat exchange tube 220 is sucked into the box body 201 through the exhaust pipe 204, and is sent into the compartment 222 through the compression pipe 203, so that the inside of the heat exchange tube 220 is in a low-pressure state, and the pressure in the compartment 222 is further increased to form a complete refrigerant circulation path. The liquid low-pressure refrigerant entering the heat exchange tube 220 will quickly absorb heat and vaporize under the low-pressure environment, while the refrigerant in the compartment 222 will quickly release heat and liquefy under the action of pressure;

[0076] In this process, as the temperature of the gas cylinder rises, the internal pressure of the compartment 222 will be further increased. As the pressure rises, the refrigerant will flow and transform more quickly, forcing the turbine 210 to rotate more quickly under the drive of the refrigerant, and driving the impeller 205, the turntable 211, the sleeve 212 and the permanent magnet rotor 214 to rotate more quickly through the square shaft 206. The faster rotation of the permanent magnet rotor 214 will increase the induced current, so that the electromagnetic heating process is accelerated, and the temperature of the gas cylinder rises more quickly. The increase in the speed of the impeller 205 will further promote the faster flow and transformation of the refrigerant, thereby forming a two-way closed-loop positive feedback regulation, and quickly realizing the heating of the gas cylinder.

[0077] During the electromagnetic heating of the gas cylinder, the temperature sensor 5 will monitor the internal temperature of the furnace body 2 in real time and feed back the temperature signal to the external control terminal. When the required temperature is reached, the external control terminal will cut off the control switch 4, disconnect the connection between the winding 215 and the coil 219, and suspend the electromagnetic heating, so that the inside of the furnace body 2 is maintained at the required temperature, and the gas cylinder is kept warm.

[0078] After the heating and heat preservation work is completed, the slide bar 224 is pulled, the slide box 202 is dragged, and the gas cylinder is dragged to one side of the box body 201. After the slide bar 224 is pulled to the maximum limit, each gas cylinder is just located inside the heat exchange tube 220. The heat emitted by the gas cylinder will further promote the refrigerant inside the heat exchange tube 220 to quickly absorb heat and vaporize, taking away the heat emitted by the gas cylinder, and stably cooling the gas cylinder;

[0079] Through the above process, the annealing, quenching, tempering and normalizing of the gas cylinder can be completed according to actual needs. At the same time, during this process, the gas cylinder will rotate synchronously with the rotation of the turntable 211, and during the rotation of the turntable 211, the roller 2231 will roll along the side wall of the slide box 202, and drive each gas cylinder to rotate through the support 223, which can make the heat exchange of the gas cylinder more uniform during the heat treatment process, and during the heating and cooling process, the turntable 211 and the partition 213 will separate the heating zone and the cooling zone inside the furnace body 2, which can further ensure the temperature rise and fall stability of the gas cylinder;

[0080] It should be added here that the initial energy required for the heat treatment is provided by the air flow delivered at the air supply pipe 302. During the heat treatment process, the energy required for the subsequent heat treatment is mainly converted from the air thermal energy absorbed during the refrigerant conversion process and the kinetic energy during the refrigerant flow process. During the heat treatment process, the air flow delivery at the air supply pipe 302 can be cut off after the device is running stably to save energy consumption. You can also choose to continue to maintain the air flow delivery at the air supply pipe 302 to make the heat exchange process more efficient and stable.
