Description

Technical Field

[0001] The present application relates to the technical field of autoclaves, and in particular to a carbon fiber autoclave. Background Art

[0002] Carbon fiber has excellent properties such as high strength, high modulus, high temperature resistance, corrosion resistance, fatigue resistance, creep resistance, conductivity, heat transfer, low relative density and small thermal expansion coefficient. It is widely used in many fields such as aerospace, medical equipment, new energy, transportation, electronics and electrical, and machinery.

[0003] The autoclave is the main production equipment for aviation composite materials. It consists of an integrated heating system, fan system, cooling system, pressure system, vacuum system, control system, safety system and other mechanical auxiliary facilities. The common structure is a cylinder with one end closed and the other end open. The autoclave provides the necessary heat and pressure for the compaction and curing of carbon fiber products.

[0004] Application number CN201820746215.1 discloses an industrial autoclave, which adopts the technical solution of comprising an autoclave body, a closed end provided at one end of the autoclave body, a motor provided on the closed end, a fan connected to the output shaft of the motor through a coupling, an electric heater connected to the air outlet of the fan, a cooler connected to the side of the electric heater away from the fan, a support base provided at the bottom of the autoclave body, a sliding base provided at the bottom of the autoclave body, a sliding slide car provided on the sliding base, a vacuum bag provided on the slide car, a sealing strip provided at the connection between the vacuum bag and the slide car, an openable or closable tank door provided at the other end of the autoclave body, and a pressure control connected to the autoclave body provided on the upper part of the autoclave body.

[0005] The above technical solution can improve the insulation effect to a certain extent, save energy and reduce heat loss, but there are still the following shortcomings. Some aviation material molds are large in size. When processing them, the internal volume of the autoclave needs to be customized according to the size of the material to be processed. When the large-sized autoclave heats or cools the interior, the fan works. Since the autoclave is a sealed cavity, the heating or cooling process mainly relies on heat conduction and convection. In large-sized autoclaves, the speed of heat conduction is relatively slow, and convection is limited by poor air circulation. Therefore, the overall heat transfer efficiency is reduced, making it difficult for the internal air to complete the cycle quickly, resulting in a problem of high local temperature. The temperature on the other side cannot be heated quickly, resulting in uneven temperature in the autoclave, affecting the curing effect of the carbon fiber product.

[0006] With regard to the problem of uneven temperature in the autoclave in the related art, no effective solution has been proposed so far. Summary of the Invention

[0038] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0039] like Figures 1 to 6 As shown, the present application relates to a carbon fiber autoclave, which comprises: a tank body 1; a tank cover 2 installed on the tank body 1; and a circulation mechanism 3 for rapidly circulating the gas in the tank body 1.

[0040] The tank cover 2 is installed on the tank body 1 through a power device. Starting the power device can drive the tank cover 2 to close or open. The power device includes: a connecting arm, a rotating shaft, and a power mechanism; the connecting arm, rotating shaft, and power mechanism are the same as those used in the Chinese patent CN202310977694.3, which belongs to the prior art and will not be described here.

[0041] The circulation mechanism 3 includes: a mounting box 31 fixedly mounted on the tank body 1; a bladder 32 fixedly mounted in the mounting box 31; a rotating pipe 33 rotatably mounted on the tank body 1; an air collecting pipe 34 connected to the rotating pipe 33; a nozzle 35 connected to the air collecting pipe 34; an air inlet pipe 36 connecting the bladder 32 and the tank body 1, the air inlet pipe 36 being installed with a first one-way valve; an air outlet pipe 37 connecting the bladder 32 and the rotating pipe 33, the air outlet pipe 37 being installed with a second one-way valve, the air outlet end of the air outlet pipe 37 being rotatably connected to the rotating pipe 33; and a driving assembly 3 for driving the bladder 32 to compress or recover. 8; The driving assembly 38 includes: a power source 381 fixedly installed in the installation box 31; a driving gear 382 fixedly installed at the output end of the power source 381; a connecting rod 383 fixedly installed on the driving gear 382; a linkage frame 384 slidably connected to the connecting rod 383; the linkage frame 384 is fixedly connected to the capsule 32; a limiting rod 387 is fixedly installed on the linkage frame 384, a limiting groove is provided in the installation box 31, and the limiting rod 387 is slidably installed in the limiting groove; a sliding groove is provided on the linkage frame 384, and the connecting rod 383 is slidably installed in the sliding groove.

[0042] A heating device is installed in the tank body 1, preferably an electric heating device.

[0043] When heating the inside of the tank body 1, the power source 381 is started to drive the driving gear 382 to rotate, and the driving gear 382 drives the connecting rod 383 to rotate. The connecting rod 383 slides in the slide groove, thereby driving the linkage frame 384 to move. When the linkage frame 384 moves, it can drive the limiting rod 387 to slide in the limiting groove. Through the limiting action of the limiting rod 387 and the limiting groove, the linkage frame 384 can move back and forth up and down.

[0044] When the linkage frame 384 moves upward, it can drive the bladder 32 to recover. At this time, the bladder 32 generates suction, the first one-way valve opens, the second one-way valve closes, and the gas in the tank body 1 is sucked into the bladder 32 through the air inlet pipe 36;

[0045] When the linkage frame 384 moves downward, it can drive the bladder 32 to compress. At this time, the first one-way valve is closed and the second one-way valve is opened. The gas in the bladder 32 is transported to the rotating pipe 33 through the outlet pipe 37 and is ejected through the gas collecting pipe 34 and the nozzle 35 in sequence.

[0046] In the present invention, the gas is sucked in from the air inlet pipe 36 and ejected through the nozzle 35 by compressing and resetting the bladder 32, adopting an upward spraying and downward suction method to achieve rapid circulation of the gas in the tank body 1, so that the heat is evenly distributed in the tank body 1 along with the air flow, thereby improving the uniformity of the temperature inside the tank body 1.

[0047] It should be added here that the power source 381 is preferably an electric motor.

[0048] Preferably, the driving assembly 38 also includes: a rack 385 fixedly mounted on the linkage frame 384; a linkage gear 386 meshing with the rack 385, two linkage gears 386 are provided, and the two linkage gears 386 are respectively fixedly sleeved on the outside of the rotating tube 33, and the rack 385 is located between the two linkage gears 386; the linkage gear 386 is fixedly sleeved on the rotating tube 33.

[0049] When the linkage frame 384 moves back and forth up and down, it can drive the two linkage gears 386 to rotate forward and reverse, and the linkage gear 386 drives the adjacent rotating pipe 33 to rotate forward and reverse, and the rotating pipe 33 drives the adjacent air collecting pipe 34 to rotate forward and reverse, and the air collecting pipe 34 drives the nozzle 35 to swing back and forth, thereby expanding the jet range of the nozzle 35, making the heat more evenly distributed in the tank body 1 with the air flow, and further improving the uniformity of the temperature inside the tank body 1.

[0050] Preferably, the circulation mechanism 3 also includes: an auxiliary component 39 for assisting the circulation of the gas in the tank body 1, and the auxiliary component 39 is provided in multiple groups; the auxiliary component 39 includes: a transmission gear 391 rotatably mounted on the tank body 1; a fan blade 392 coaxially connected to the transmission gear 391; and the transmission gear 391 and the drive gear 382 are meshed with each other.

[0051] When the driving gear 382 rotates, it can drive the transmission gear 391 to rotate, thereby driving the fan blades 392 to rotate. The rotation of the fan blades 392 produces horizontal blowing, thereby accelerating the flow of air, making the gas in the tank body 1 form a horizontal circulation, thereby improving the gas circulation efficiency and further improving the uniformity of the temperature inside the tank body 1.

[0052] Since multiple groups of auxiliary components 39 are provided, the lateral blowing volume can be increased, and the gas circulation efficiency is further improved.

[0053] In the present invention, by starting the power source 381, the linkage frame 384 can be driven to move back and forth up and down. On the one hand, it drives the compression and recovery of the capsule 32, thereby realizing the rapid circulation of the gas, so that the heat is evenly distributed in the tank body 1 with the airflow, thereby improving the uniformity of the temperature inside the tank body 1. On the other hand, it drives the nozzle 35 to swing back and forth, thereby expanding the jet range of the nozzle 35, so that the heat is more evenly distributed in the tank body 1 with the airflow, further improving the uniformity of the temperature inside the tank body 1. On the other hand, it drives multiple sets of fan blades 392 to rotate, so that the gas in the tank body 1 forms a horizontal circulation, thereby improving the gas circulation efficiency.

[0054] Preferably, it also includes: a fixing mechanism 4 for fixing the tank cover 2; the fixing mechanism 4 includes: a fixing rod 41 fixedly installed in the tank cover 2; a fixing plate 42 fixedly connected to the fixing rod 41; a fixing tube 44 fixedly installed on the fixing plate 42; a plug rod 46 installed on the fixing tube 44; a piston 45 fixedly connected to the plug rod 46, and the piston 45 is slidably installed in the fixing tube 44; a return spring 47 for driving the plug rod 46 to return, one end of the return spring 47 is fixedly connected to the piston 45, and the other end of the return spring 47 is fixedly connected to the inner wall of the fixing tube 44; a liquid supply component 48 for providing hydraulic oil to the fixing tube 44; An annular plate 43 is fixedly installed, and a plug-in hole matching the plug-in rod 46 is provided on the annular plate 43, and a sealing ring 8 is fixedly sleeved on the annular plate 43; the liquid supply component 48 includes: a linkage block 482 slidably installed on the fixed rod 41; a power source 481 for driving the linkage block 482 to move; a liquid storage tube 483 fixedly installed in the tank cover 2; a liquid guide tube 486 connecting the liquid storage tube 483 and the fixed tube 44; a movable rod 484 installed through the liquid storage tube 483; a piston 485 fixedly installed at one end of the movable rod 484, and the piston 485 is slidably installed in the liquid storage tube 483; the other end of the movable rod 484 is fixedly connected to the linkage block 482.

[0055] When the can lid 2 is closed, the inner wall of the can lid 2 fits against the sealing ring 8 , thereby improving the sealing between the can lid 2 and the can body 1 and preventing heat loss in the can body 1 .

[0056] At the same time, by starting power source 2 481, the connecting block 482 is driven to move, the connecting block 482 drives the movable rod 484 to move, and the movable rod 484 drives the piston 2 485 to move, so that the hydraulic oil in the liquid storage tube 483 can be squeezed, so that the hydraulic oil flows into the fixed tube 44 through the liquid guide tube 486, and pushes the piston 1 45 to move. The piston 1 45 drives the connecting rod 46 to be inserted into the connecting hole, and drives the return spring 47 to be compressed. At this time, the closed tank cover 2 is fixed, avoiding the problem that the tank cover 2 and the tank body 1 are displaced when the pressure in the tank body 1 is increased, resulting in poor sealing effect.

[0057] When it is necessary to open the tank cover 2, the power source is started to drive the linkage block 482 to reset, the linkage block 482 drives the movable rod 484 to reset, and the movable rod 484 drives the piston 2 485 to reset, so that the hydraulic oil in the fixed tube 44 can be sucked into the liquid storage tube 483. At this time, the elastic force of the reset spring 47 can drive the plug rod 46 to reset, so that the plug rod 46 is separated from the plug hole, and the fixed state of the tank cover 2 is released.

[0058] It should be added here that the power source 2 481 is preferably a telescopic cylinder.

[0059] Preferably, a support rod 5 is fixedly mounted on the linkage block 482 , and a support plate 6 is fixedly mounted on the end of the support rod 5 ; a plurality of support rods 5 are provided and are evenly distributed along the circumference of the linkage block 482 , and each support rod 5 corresponds to a support plate 6 .

[0060] When the linkage block 482 moves, it can drive the support rod 5 to move, and the support rod 5 drives the support plate 6 to abut against the inner side of the tank cover 2, thereby supporting the tank cover 2, improving the stability of the tank cover 2, and preventing the tank body 1 from increasing and decreasing pressure and heating and cooling in the process of too fast speed. The temperature and pressure of various parts of the tank cover 2 change unevenly, generating thermal stress and pressure difference, making the tank cover 2 easy to deform, and preventing the tank cover 2 from leaking, resulting in energy waste.

[0061] Furthermore, the plurality of support plates 6 support the can cover 2 from different directions, thereby improving the supporting effect on the can cover 2 .

[0062] In addition, the support plate 6 is arc-shaped, and the curvature of the support plate 6 matches that of the tank cover 2 , so that the support plate 6 fits better on the inner side of the tank cover 2 , further improving the supporting effect on the tank cover 2 .

[0063] Preferably, a mounting opening is provided on the fixing plate 42 , and a fan 7 is fixedly installed in the mounting opening; two fans 7 are provided, and the two fans 7 are arranged up and down, and the blowing directions of the two fans 7 are opposite.

[0064] When the circulation mechanism 3 is started, the two fans 7 are started. At this time, the fan 7 located at the bottom blows air toward the tank cover 2, and the fan 7 located at the top blows air into the tank body 1, so that the air flow in the tank body 1 forms a horizontal circulation, thereby further improving the uniformity of the temperature in the tank body 1.

[0065] The working principle of the device is as follows:

[0066] When heating the tank body 1, the circulation mechanism 3 is started to achieve rapid circulation of gas, so that the heat is evenly distributed in the tank body 1 along with the air flow, thereby improving the uniformity of the temperature inside the tank body 1. When the tank cover 2 is closed, the inner wall of the tank cover 2 fits against the sealing ring 8, thereby improving the sealing between the tank cover 2 and the tank body 1 and avoiding heat loss in the tank body 1. At the same time, by starting the fixing mechanism 4, the closed tank cover 2 is fixed, avoiding the problem of displacement of the tank cover 2 and the tank body 1 when the pressure in the tank body 1 is increased, resulting in poor sealing effect.

[0067] From the above description, it can be seen that this application achieves the following technical effects:

[0068] In the present invention, by starting the power source 381, the linkage frame 384 can be driven to move back and forth up and down. On the one hand, it drives the compression and recovery of the capsule 32, thereby realizing the rapid circulation of the gas, so that the heat is evenly distributed in the tank body 1 with the airflow, thereby improving the uniformity of the temperature inside the tank body 1. On the other hand, it drives the nozzle 35 to swing back and forth, thereby expanding the jet range of the nozzle 35, so that the heat is more evenly distributed in the tank body 1 with the airflow, further improving the uniformity of the temperature inside the tank body 1. On the other hand, it drives multiple sets of fan blades 392 to rotate, so that the gas in the tank body 1 forms a horizontal circulation, thereby improving the gas circulation efficiency.

[0069] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
