Description

Technical Field

[0001] The present invention relates to the technical field of composite material processing, and particularly relates to an extra-long multi-fan autoclave. Background Art

[0002] As the main production equipment for aviation composite parts, the autoclave is a large pressure vessel with an integral heating system. Since the autoclave is a pressure vessel, its common structure is a cylinder with one end closed and the other end open, providing the necessary heat and pressure for the compaction and curing of advanced composite products.

[0003] The autoclave includes a tank body, a heating system, a fan system, a cooling system, a pressure system, a vacuum system, and control software. During use, first, vacuum is drawn to prevent bubbles from generating during the curing of composite materials, and then heating and inflation are carried out to provide a high-temperature and high-pressure environment for the composite materials to complete curing. The opening and closing of the autoclave lid are mainly divided into two methods: hydraulic and manual. The sealing points of the lid are single and the sealing performance is poor. Once gas leakage occurs, the curing quality will be reduced. In addition, when the autoclave is depressurized after the curing of composite materials is completed, the direct discharge of high-temperature and high-pressure gas will cause energy waste. Therefore, it is necessary to propose an energy-saving extra-long multi-fan autoclave. Summary of the Invention

[0004] In order to overcome the disadvantages of poor sealing effect of the autoclave and inability to reuse high-temperature and high-pressure gas in the prior art, the present invention provides an extra-long multi-fan autoclave.

[0005] To achieve the above object, the present invention provides the following technical solution: An extra-long multi-fan autoclave, including a base, an autoclave, a vacuum pump, and a lithium battery. The autoclave is fixedly connected to the upper surface of the base. The vacuum pump and the lithium battery are both installed on the upper surface of the base, and the vacuum pump is connected to the outer wall of the autoclave through a pipeline. The vacuum pump is used to draw vacuum on the autoclave to prevent bubbles from generating in the composite material. A first solenoid valve is installed on the outer wall of the autoclave, and the first solenoid valve is connected to an air pump through a pipeline for pressurizing the autoclave. A plurality of blocks are installed equidistantly along the circumferential direction on the left outer edge of the autoclave. A pressurizing mechanism is installed at the center position of the lid of the autoclave. The sealing performance of the autoclave and the lid is improved by the cooperation of the pressurizing mechanism and the blocks. An energy conversion mechanism is installed at the right end of the upper surface of the base. A second solenoid valve is installed at the right end of the bottom of the autoclave.

A turbine is installed at the center position of the right wall of the inner cavity of the autoclave. A motor for driving the turbine to rotate is installed on the right outer wall of the autoclave. The rotation of the turbine can generate suction to make the gas in the autoclave flow.

[0006] Preferably, the pressurizing mechanism includes a transmission component and a supercharging component. The transmission component is installed at the center of the left side wall of the autoclave lid, and the supercharging component is installed on the right side of the transmission component.

[0007] Preferably, the transmission component includes a box body installed at the center of the left side wall of the autoclave lid.

One end of the connecting rod is connected to the inner side of the sliding rod by a pin shaft, and the other end of the connecting rod is connected to the outer wall of the first gear by a pin shaft. When the first gear rotates, the connecting rod pulls the sliding rod to move back and forth. An extrusion block is installed on the outer side of the sliding rod; under the condition that the first gear rotates, the sliding rod moves outward or inward. When the extrusion block and the stop block are mutually extruded, the sealing pressure between the lid and the autoclave is increased.

[0008] Preferably, the connection position of the connecting rod and the first gear is at half of the pitch circle radius of the first gear.

[0009] Preferably, the outer side of the extrusion block and the left side of the stop block are both triangular in shape.

[0010] Preferably, the supercharging component includes a piston cylinder installed on the right side wall of the box body. A piston that can slide left and right is inserted into the inner cavity of the piston cylinder. The piston is pushed to move left by the internal air pressure of the autoclave. A spring is installed on the left side of the piston. A piston rod that can slide left and right is inserted into the center position of the left side wall of the piston cylinder. The right end of the piston rod is connected to the piston, and the left end of the piston rod extends out of the left side wall of the box body. A number of teeth that are meshed and connected with the first gear are installed on the middle part of the outer wall of the piston rod from left to right; by using the air pressure to push the piston to move left, the teeth can make the first gear rotate.

[0011] Preferably, the left side of the outer wall of the piston rod is sprayed with pigment.

[0012] Preferably, the energy conversion mechanism includes a water tank installed at the right end of the upper surface of the base. A water injection port is provided at the top of the water tank. A heat dissipation pipe is installed at the bottom of the inner cavity of the water tank, and the left end of the heat dissipation pipe is connected to the second solenoid valve through a pipeline. A switching component is installed at the right end of the top of the water tank. An impeller housing is installed on the top of the switching component. A first rotating shaft is installed at the center of the left side wall of the impeller housing through a bearing. A second gear and an impeller are respectively installed at the left and right ends of the first rotating shaft. When air flow enters the impeller housing, the air flow can push the impeller to rotate. A generator electrically connected to the lithium battery is installed at the left end of the upper surface of the water tank. A third gear meshed with the second gear is installed at the input end of the generator. The transmission ratio of the second gear to the third gear is greater than 1, making it easier for the first rotating shaft to drive the generator to rotate; by using air pressure and steam pressure to push the impeller to rotate, under the condition of the transmission between the second gear and the third gear, the rotor of the generator rotates, converting mechanical energy into electrical energy.

[0013] Preferably, the heat dissipation pipe is a serpentine coiled pipe.

[0014] Preferably, the switching component includes a valve body installed at the right end of the upper surface of the water tank. The right side of the lower surface of the valve body is connected to the heat dissipation pipe through a pipeline. The left side of the lower surface of the valve body is communicated with the water tank. The top of the valve body is connected to the bottom of the impeller housing. A valve core capable of sliding left and right is inserted into the inner cavity of the valve body. A base is installed on the right side wall of the valve body. A push-pull rod is horizontally inserted into the right side wall of the valve body. The left end of the push-pull rod is connected to the valve core. A rack is installed at the right end of the push-pull rod. A second rotating shaft is installed at the top front of the base through a bearing. A counterweight and a fourth gear are respectively installed at the front and rear ends of the second rotating shaft. The fourth gear is meshed and connected with the rack. When the counterweight rotates clockwise or counterclockwise, the rack pulls the valve core to move left or right. A limiting block is installed on the front surface of the base directly below the second rotating shaft to limit the counterweight through the limiting block; by moving the valve core left and right, the switching of air flow and water vapor entering the impeller housing is carried out.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. Utilize the internal air pressure of the autoclave to push the piston of the pressurizing component to move leftward. Drive the first gear to rotate through the teeth on the piston rod, drive the connecting rod to pull the sliding rod to move outward, and enable the extrusion block to mutually extrude with the triangular inclined surface of the stop block, thereby dynamically enhancing the sealing pressure between the tank cover and the tank body as the air pressure increases; this design changes the defect of the single sealing point of the traditional autoclave, and avoids the decline of the curing quality caused by gas leakage; at the same time, the pressurizing mechanism at the center of the tank cover and the circumferentially distributed stop blocks cooperate with each other to form a uniform sealing pressure distribution. Compared with the structure of a single sealing point in the prior art, the overall sealing performance is significantly improved, ensuring the stability of the high-temperature and high-pressure environment.

[0016] 2. During pressure relief, the hot air flows through the serpentine heat dissipation pipe to heat the water in the water tank, and at the same time drives the impeller to rotate, drives the generator to generate electricity through gear transmission, and converts the gas kinetic energy into electrical energy and stores it in the lithium battery. The serpentine design of the heat dissipation pipe expands the contact area with water and improves the heat exchange efficiency; the switching component realizes the secondary utilization of energy by the linkage of the counterweight and the valve core to guide the water vapor in the water tank to drive the impeller to continue generating electricity after the pressure relief is completed, and avoids the energy waste caused by the direct discharge of high-temperature and high-pressure gases in the traditional technology.

[0017] 3. The turbine on the inner wall of the autoclave is driven by a motor to rotate, generating suction to make the gas flow directionally. Cooperate with the air duct plate to limit the ventilation direction, form a uniform air flow circulation, ensure the consistency of the temperature field and pressure field in the tank, and avoid the curing defects of the composite material caused by uneven local temperature; the rotation of the turbine drives the gas to flow from left to right, and after being heated by the heater, it acts on the composite material uniformly. Compared with the traditional static heating method, the curing time can be shortened and the performance consistency of the product can be improved.

[0018] 4. The outer wall of the piston rod is sprayed with pigment, and its position moves with the change of the air pressure in the autoclave. The pressure state in the autoclave can be visually judged through the degree of color exposure, avoiding misjudgment caused by the failure of the pressure gauge, and preventing high-pressure gas from injuring the staff when opening the autoclave; the combined monitoring of the pressure reducing valve, temperature sensing probe and pressure gauge, combined with the dynamic sealing structure, forms multiple layers of safety protection to ensure that the equipment can relieve pressure and alarm in time under abnormal working conditions.

[0019] 5. The design of multiple fans and air duct plates can meet the air flow circulation requirements of ultra-long tanks, solve the problem of uneven temperature in traditional autoclaves when the length-diameter ratio is too large, and expand the processing applicability of the equipment for large composite components; the electric energy generated by the energy conversion mechanism is stored in the lithium battery, which can supply power to the electric control system of this equipment (such as solenoid valves, motors), reducing the dependence on external energy, and is especially suitable for off-line or energy-limited scenarios.

[0020] Through the dynamic optimization of the sealing structure, the innovative design of the energy recovery system and the precise control of the air flow circulation, the present invention has achieved multiple technical breakthroughs in energy saving, safety and efficiency while improving the curing quality of composite materials, overcoming the defects of poor sealing, energy waste and high operation risk of traditional autoclaves, and has significant engineering application value and economic benefits.

Detailed implementation mode

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides a technical solution: an extra-long multi-fan autoclave, as Figures 1-7As shown in the figure, it includes a base 1, an autoclave 2, a vacuum pump 3, and a lithium battery 4. The autoclave 2 is fixedly connected to the upper surface of the base 1. By providing a high-temperature and high-pressure environment through the autoclave 2, the composite material is cured. A pressure reducing valve, a temperature sensing probe, and a pressure gauge are installed on the top of the autoclave 2. A heater and a condenser are installed at the bottom of the inner wall of the autoclave 2. The heater is used to raise the temperature of the autoclave 2, and the condenser cools down the autoclave 2. Both the vacuum pump 3 and the lithium battery 4 are installed on the upper surface of the base 1, and the vacuum pump 3 is connected to the outer wall of the autoclave 2 through a pipeline. The vacuum pump 3 is used to evacuate the autoclave 2 to prevent air bubbles from generating in the composite material. A first solenoid valve 5 is installed on the outer wall of the autoclave 2. The first solenoid valve 5 is connected to an air pump through a pipeline and is used to pressurize the autoclave 2. A plurality of blocks 6 are installed equidistantly along the circumferential direction on the left outer edge of the autoclave 2. A pressurizing mechanism 7 is installed at the center position of the lid of the autoclave 2. By the cooperation of the pressurizing mechanism 7 and the blocks 6, the sealing performance between the autoclave 2 and the lid is improved. An energy conversion mechanism 8 is installed at the right end of the upper surface of the base 1. A second solenoid valve 9 is installed at the right end of the bottom of the autoclave 2. The second solenoid valve 9 is connected to the energy conversion mechanism 8 through a pipeline. An air duct plate 10 is installed at the bottom of the inner wall of the autoclave 2 to restrict the ventilation direction. A partition 11 is installed at the right end of the inner cavity of the autoclave 2. A turbine 12 is installed at the center position of the right wall of the inner cavity of the autoclave 2. A motor 13 for driving the turbine 12 to rotate is installed on the right outer wall of the autoclave 2. The rotation of the turbine 12 can generate suction force to make the gas flow in the autoclave 2.

[0025] As a preferred solution, further, as Figure 4 shown, the pressurizing mechanism 7 includes a transmission component 71 and a boosting component 72. The transmission component 71 is installed at the center position of the left side wall of the lid of the autoclave 2, and the boosting component 72 is installed on the right side of the transmission component 71.

[0026] As a preferred solution, further, as Figure 4As shown in the figure, the transmission assembly 71 includes a box body 711 installed at the center position of the left side wall of the lid of the autoclave 2. A number of first gears 712 are connected to the inner cavity of the box body 711 along the circumferential direction by pin shafts. A number of limiting sleeves 713 are installed on the side wall of the box body 711 at equal intervals along the circumferential direction. A sliding rod 714 is inserted into the inner cavity of the limiting sleeve 713. One end of a connecting rod 715 is connected to the inner side of the sliding rod 714 by a pin shaft, and the other end of the connecting rod 715 is connected to the outer wall of the first gear 712 by a pin shaft. When the first gear 712 rotates, the connecting rod 715 pulls the sliding rod 714 to move back and forth. The connection position of the connecting rod 715 and the first gear 712 is at half of the pitch circle radius of the first gear 712. The torque of the first gear 712 driving the connecting rod 715 to rotate is less than the torque of the pressurizing assembly 72 driving the first gear 712 to rotate, making it easier for the pressurizing assembly 72 to drive the sliding rod 714 to move. An extrusion block 716 is installed on the outer side of the sliding rod 714. The outer sides of the extrusion block 716 and the left side of the stop block 6 are both triangular in shape. When the extrusion block 716 and the stop block 6 are pressed against each other, the sealing performance of the lid and the autoclave 2 is enhanced during closing.

[0027] As a preferred solution, further, the pressurizing assembly 72 includes a piston cylinder 721 installed on the right side wall of the box body 711. A piston 722 that can slide left and right is inserted into the inner cavity of the piston cylinder 721. The piston 722 is pushed to move left by the internal air pressure of the autoclave 2. A spring 723 is installed on the left side of the piston 722. A piston rod 724 that can slide left and right is inserted into the center position of the left side wall of the piston cylinder 721. The right end of the piston rod 724 is connected to the piston 722, and the left end of the piston rod 724 extends out of the left side wall of the box body 711. A pigment is sprayed on the left side of the outer wall of the piston rod 724. The piston rod 724 can slide left and right under the condition of the change of the air pressure in the autoclave 2. By using the change of the color on the piston rod 724, the pressure in the autoclave 2 can be accurately judged, avoiding the wrong opening of the autoclave 2 caused by the wrong report of the pressure gauge. A number of teeth 725 that are meshed with the first gear 712 are installed on the middle part of the outer wall of the piston rod 724 from left to right.

[0028] Pressure display function: A pigment such as a red warning coating is sprayed on the left side of the outer wall of the piston rod 724. When the air pressure in the autoclave 2 changes, the piston rod 724 moves left and right with the piston 722, and the exposed area of the pigment changes accordingly. By observing the degree of the pigment exposed, the pressure state in the tank can be visually judged, avoiding misoperation caused by the failure of the pressure gauge.

[0029] Pressurization and sealing process: When the air pressure in the autoclave 2 increases, the air pressure pushes the piston 722 to move left, driving the piston rod 724 to move left. The teeth 725 drive the first gear 712 to rotate. The first gear 712 pulls the sliding rod 714 to slide outwards through the connecting rod 715, so that the triangular inclined surface of the extrusion block 716 is pressed against the inclined surface of the stop block 6. The sealing pressure between the lid and the autoclave 2 increases synchronously with the air pressure, achieving a dynamic sealing effect of "the higher the air pressure, the tighter the seal".

[0030] Pressure relief and reset process: When the pressure is relieved after the composite material is cured, the air pressure in the autoclave 2 decreases. The spring 723 pushes the piston 722 to reset to the right, the piston rod 724 moves to the right, the tooth 725 drives the first gear 712 to rotate in the reverse direction, the slide rod 714 and the extrusion block 716 retract inward. At the same time, the pigment on the left side of the piston rod 724 is gradually blocked by the box body 711. When the pigment is completely hidden, it indicates that the pressure in the tank has dropped to a safe range, and the tank lid can be safely opened.

[0031] As a preferred solution, further, as Figure 5 、 Figure 6 and Figure 7 shown, the energy conversion mechanism 8 includes a water tank 81 installed at the right end of the upper surface of the base 1. The top of the water tank 81 is provided with a water injection port. A heat dissipation pipe 82 is installed at the bottom of the inner cavity of the water tank 81, and the left end of the heat dissipation pipe 82 is connected to the second solenoid valve 9 through a pipeline. The heat dissipation pipe 82 is a serpentine coil pipe, which expands the contact area between the heat dissipation pipe 82 and water and improves the heating efficiency. A switching component 83 is installed at the right end of the top of the water tank 81. An impeller housing 84 is installed on the top of the switching component 83. A first rotating shaft 85 is installed at the center of the left side wall of the impeller housing 84 through a bearing. A second gear 86 and an impeller 87 are respectively installed at the left and right ends of the first rotating shaft 85. When air flow enters the impeller housing 84, the air flow can push the impeller 87 to rotate. A generator 88 electrically connected to the lithium battery 4 is installed at the left end of the upper surface of the water tank 81. A third gear 89 meshed with the second gear 86 is installed at the input end of the generator 88. The transmission ratio of the second gear 86 to the third gear 89 is greater than 1, making it easier for the first rotating shaft 85 to drive the generator 88 to rotate.

[0032] As a preferred solution, further, as Figure 6 shown, the switching component 83 includes a valve body 831 installed at the right end of the upper surface of the water tank 81. The right side of the lower surface of the valve body 831 is connected to the heat dissipation pipe 82 through a pipeline. The left side of the lower surface of the valve body 831 is communicated with the water tank 81. The top of the valve body 831 is connected to the bottom of the impeller housing 84. A valve core 832 capable of sliding left and right is inserted into the inner cavity of the valve body 831. A base 833 is installed on the right side wall of the valve body 831. A push-pull rod 834 is horizontally inserted into the right side wall of the valve body 831. The left end of the push-pull rod 834 is connected to the valve core 832, and a rack 835 is installed at the right end of the push-pull rod 834. A second rotating shaft 836 is installed at the top of the front of the base 833 through a bearing. A counterweight 837 and a fourth gear 838 are respectively installed at the front and rear ends of the second rotating shaft 836, and the fourth gear 838 is meshed with the rack 835. When the counterweight 837 rotates clockwise or counterclockwise, the rack 835 pulls the valve core 832 to move left or right. A limit block 839 is installed at the front of the base 833 directly below the second rotating shaft 836 to limit the counterweight 837 through the limit block 839.

[0033] Energy recovery during the pressure relief stage: When the autoclave 2 is depressurized, the second solenoid valve 9 is opened, and the high-temperature and high-pressure gas enters the heat dissipation pipe 82 through the pipeline, transferring heat to the water in the water tank 81 through the serpentine coiled pipe; at the same time, the gas enters the impeller housing 84 through the right channel of the valve body 831, pushing the impeller 87 to rotate, driving the first rotating shaft 85 and the second gear 86 to rotate.

[0034] The second gear 86 drives the rotation of the rotor of the generator 88 through the third gear 89, converting mechanical energy into electrical energy and storing it in the lithium battery 4; since the transmission ratio of the second gear 86 to the third gear 89 is greater than 1, the driving resistance of the impeller 87 can be reduced, improving the energy conversion efficiency.

[0035] Steam energy recovery after pressure relief is completed: When the pressure relief of the autoclave 2 is completed, manually or automatically rotate the counterweight 837 counterclockwise, driving the fourth gear 838 to rotate counterclockwise, pulling the push rod 834 to move leftward through the rack 835, causing the valve core 832 to slide to the right, closing the channel of the heat dissipation pipe 82 and opening the channel of the water tank 81.

[0036] At this time, the water vapor generated by the heated water in the water tank 81 enters the impeller housing 84 through the left channel of the valve body 831, pushing the impeller 87 to continue rotating, continuously driving the generator 88 to generate electricity, realizing the secondary utilization of energy.

[0037] Working principle: Step 1: Place the composite material on the air duct plate 10, close the tank lid, perform vacuum suction on the autoclave 2 through the vacuum pump 3 to prevent bubbles from generating during curing, and then let the air pump inflate the autoclave 2. The motor 13 drives the turbine 12 to rotate, and the turbine 12 sucks air from left to right, and the generated air flow passes through the air duct plate 10 and is discharged from right to left. The heater in the autoclave 2 heats the air flow, and the air flow is used to evenly heat the autoclave 2, curing the composite material under high-temperature and high-pressure conditions; Step 2: During the pressure increase process of the autoclave 2, the air pressure pushes the piston 722 to move leftward along the piston cylinder 721, and the teeth 725 on the piston rod 724 mesh with the first gear 712 to drive, causing the connecting rod 715 to pull the sliding rod 714 to move outward, and the extrusion block 716 and the stop block 6 are mutually extruded, prompting the tank lid to be tightly pressed on the autoclave 2. Therefore, the pressing force can be increased following the increase of air pressure, improving the sealing performance; Step 3: After the curing of the composite material is completed, when the second solenoid valve 9 is opened for pressure relief, the elastic force of the spring 723 pushes the piston 722 to move rightward, the piston rod 724 moves rightward, and the color displayed on the piston rod 724 can accurately judge the pressure in the autoclave 2, preventing the autoclave 2 from being opened under high pressure and harming the staff; Step 4: During the pressure relief process, the hot air flow passes through the heat dissipation pipe 82 and enters the valve body 831. The heat brought by the air flow heats the water. After the air flow enters the impeller housing 84, it drives the impeller 87 to rotate. Under the transmission condition of the second gear 86 and the third gear 89, the rotor of the generator 88 can be rotated, and the mechanical energy is converted into electrical energy and stored in the lithium battery 4. After the pressure relief is completed in the autoclave 2, rotate the counterweight 837 counterclockwise to cause the fourth gear 838 to rotate counterclockwise, and let the rack 835 pull the valve core 832 to move rightward. The valve core 832 closes the heat dissipation pipe 82. The water vapor in the water tank 81 enters the impeller housing 84 along the inner cavity of the valve body 831. The water vapor pressure drives the impeller 87 to rotate, enabling the generator 88 to generate electricity. Therefore, energy recovery and utilization are achieved.
