Description

Technical Field

[0001] This invention relates to the field of autoclaves, and in particular to an apparatus and method for replacing the baffle plate of an autoclave, and an autoclave. Background Technology

[0002] Autoclave molding technology is widely used in the preparation of high-performance composite material components in high-end manufacturing fields such as aerospace and new energy. Existing autoclaves or small heat treatment devices typically incorporate internal structures to organize circulating airflow, guiding the high-temperature, high-pressure medium to form a predetermined flow path within the vessel, thereby improving heat transfer conditions and temperature distribution around the sample. The specific forms of these structures are not entirely identical; they can manifest as flow guides, air ducts, baffles, rectifiers, flow dividers, or porous structures with different opening forms. Despite differences in name, installation location, and structural form, their essential function is to guide, rectify, distribute, or partially obstruct the circulating airflow to adjust the airflow velocity distribution, flow direction, and turbulence intensity within the vessel, thereby affecting the convective heat transfer coefficient of the workpiece surface, the local temperature gradient, and the thermal response characteristics during material curing.

[0003] For research on hot pressing molding and processes of composite materials, such internal airflow organization structure is one of the important factors affecting the uniformity of the thermal environment inside the tank and the consistency of molding. When carrying out process optimization, parameter comparison and mechanism analysis, it is often desirable to switch flow field control components of different forms or different structural parameters on the same equipment. For example, using porous plate structures with different pore diameters, opening ratios or opening distributions, in order to investigate the variation law of sample temperature uniformity, heating response, curing rate and molding quality under different flow field conditions.

[0004] However, the perforated baffles in existing autoclaves or small heat treatment units are mostly fixed. If the baffles need to be replaced to switch flow field schemes, the traditional method requires a complete shutdown, depressurization, and cooling. Only after the temperature inside the tank drops to a safe operating range and the pressure is released to atmospheric pressure can the tank be opened and the baffles replaced manually. After replacement, it is necessary to reseal, evacuate, and re-heat and pressurize to the required operating conditions. The entire process usually takes several hours or even longer. This not only forces the interruption of the thermal history of the operating conditions, causing the workpiece to undergo additional thermal cycles during the cooling-heating process, affecting the controllability of curing quality, but also makes it difficult to compare the processing results of the same batch of workpieces under different baffle conditions under the same thermal history benchmark, seriously restricting the reliability and repeatability of process data. At the same time, operators need to manually enter the tank to disassemble and install the baffles. The positioning accuracy of the baffles depends on manual experience, which may lead to quality problems such as improper installation of the sealing ring and misalignment of the baffles. The assembly efficiency is low and the operation safety risk is high, making it difficult to meet the needs of high-frequency, multi-condition rapid switching. Summary of the Invention

[0005] The purpose of this invention is to address the problems of existing autoclave baffle replacement technology, which requires complete shutdown, depressurization, cooling, manual replacement of the baffle, resealing, vacuuming, and reheating and pressurizing to the required operating conditions. This is time-consuming and labor-intensive. Furthermore, it is difficult to compare the processing results of the same batch of workpieces under different baffle conditions under the same thermal history benchmark, which seriously restricts the reliability and repeatability of process data. Manual baffle replacement also poses safety and quality risks, has low assembly efficiency, and cannot meet the requirements of high frequency and rapid switching of multiple operating conditions. Therefore, this invention provides a device and method for replacing autoclave baffles, as well as an autoclave.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] In a first aspect, the present invention provides an apparatus for replacing a baffle plate in an autoclave, comprising a partition system and a replacement system; the partition system is connected to an autoclave body, the autoclave body including a front compartment and a rear compartment, the partition system being used to provide either a conductive or sealed partition between the front compartment and the rear compartment; the replacement system is connected to the autoclave body, the replacement system being connected to at least one baffle plate assembly, each baffle plate assembly including a baffle plate; when the replacement system is connected to one baffle plate assembly, the baffle plate assembly is used for a sealed connection to the rear compartment, and the replacement system is capable of replacing the baffle plate assembly... After removing the autoclave and replacing the baffles with different opening shapes, opening ratios, pore diameters, and / or pore distributions, the replacement system can move the baffle assembly relative to the autoclave and seal it in place. When the replacement system connects at least two baffle assemblies, the opening shapes, opening ratios, pore diameters, and / or pore distributions on each baffle are different. One baffle assembly is used for a sealable connection to the aft compartment. The replacement system can remove one baffle assembly relative to the autoclave and move another baffle assembly relative to the autoclave and seal it in place.

[0008] The device for replacing guide vanes in an autoclave, as described in this invention, connects or disconnects the front and rear compartments via a partition system. When disconnected, the guide vane assembly connected to the rear compartment can be replaced via the replacement system, thus enabling the replacement of different guide vanes. During this process, the environment of the workpiece placed in the front compartment remains unchanged. After the guide vane is replaced, the rear compartment is resealed, and the rear compartment is heated and pressurized to the operating conditions of the front compartment. The partition system then connects the front and rear compartments, allowing the process flow to continue using the replaced guide vane. The thermal history of the workpiece is uninterrupted throughout the process. The processing results of the same batch of workpieces under different deflector conditions are compared under the same thermal history benchmark. The reliability and repeatability of the process data are excellent. At the same time, the deflector assembly is automatically loaded and unloaded relative to the rear compartment. Only the deflector plate on the deflector assembly needs to be loaded and unloaded by the operator. No personnel need to enter the compartment to operate, which reduces safety and quality risks, improves assembly efficiency, and meets the requirements of high frequency and rapid switching of multiple working conditions. The device has a simple structure, is easy to use, and has good effect.

[0009] As a preferred embodiment of the present invention, the partition system includes a partition plate, a valve body, and a first motor; the shape of the partition plate matches the shape of the inner edge of the autoclave, the partition plate is rotatably connected to the separation between the front compartment and the rear compartment inside the autoclave, and a sealing ring is connected to the outer edge of the partition plate and / or the inner edge of the separation; the valve body is connected to the autoclave and the partition plate; the first motor is located outside the autoclave and is connected to the valve body, and the first motor drives the partition plate to rotate through the valve body.

[0010] With this structural design, the shape of the partition plate matches the inner edge of the autoclave, ensuring a tight fit between the partition plate and the interior of the autoclave, effectively separating the front and rear compartments. Sealing rings are provided on the outer edge of the partition plate and / or the inner edge of the separation point, enhancing the airtightness of the partition and preventing cross-contamination or leakage of media between compartments, thus improving process control precision and safety. The first motor, located outside the autoclave, drives the partition plate to rotate via the valve body, achieving automatic control of the partition plate's opening and closing, improving operational convenience and system integration. The first motor's location outside the autoclave avoids the influence of harsh operating conditions such as high temperature and high pressure, facilitating equipment maintenance and extending its service life; maintenance is convenient and highly reliable. The partition system integrates the partition plate, the valve body, and the first motor, featuring a compact structure, high functional integration, and stable collaborative operation, making it suitable for autoclaving processes requiring precise control of compartment isolation.

[0011] As a preferred embodiment of the present invention, the replacement system includes a bracket, a drive assembly, a slide table, and a slide rail; the bracket spans the rear compartment, and the upper and lower parts of the bracket are respectively connected to the slide rails, with the autoclave located between two of the slide rails; the top and bottom of each deflector assembly are respectively connected to the slide table, and the slide table is slidably connected to the corresponding slide rail; the drive assembly is connected to the bracket, and the drive assembly drives each deflector assembly to slide along the slide rail toward or away from the rear compartment.

[0012] This structural design, through the cooperation of the sliding table and the slide rail, allows the guide vane assembly to slide in and out of the rear compartment along the support, enabling rapid installation, disassembly, or replacement, significantly improving maintenance and operational efficiency. The support spans the rear compartment and is equipped with slide rails at both the top and bottom, with the autoclave body located between the two slide rails, forming a symmetrical support structure that enhances overall rigidity and operational stability, ensuring alignment and safety during the movement of the guide vane assembly. The drive assembly is integrated into the support and can automatically drive the guide vane assembly to slide along the slide rails, achieving automated control, reducing manual intervention, and improving the system's automation level. The slide rails are arranged perpendicular to the axis of the autoclave body, making full use of the external space of the autoclave body, avoiding interference with the internal process area of ​​the autoclave body, and facilitating equipment maintenance and expansion. The replacement system, by moving the guide vane assembly out of and into the compartment, is applicable to the replacement needs of various specifications of guide vanes, possessing good versatility and adaptability, and can be widely used in autoclave equipment under different operating conditions.

[0013] As a further preferred technical solution of the present invention, the driving component includes a second motor and a lead screw; the lead screw is rotatably connected to the bracket, the lead screw is arranged parallel to the slide rail, the slide table at the top of each of the guide plate assemblies is threaded to the lead screw, or the slide table at the bottom of each of the guide plate assemblies is threaded to the lead screw; the second motor is connected to the bracket, and the second motor connects to and drives the lead screw to rotate.

[0014] This structural design, employing a lead screw drive system, allows for precise position adjustment of the guide vane assembly along the slide rail via the second motor, meeting the accurate positioning requirements for guide vane replacement. The lead screw is parallel to the slide rail, and the slide table is threadedly connected to the lead screw, forming a stable transmission pair. This ensures smooth operation of the guide vane assembly during movement, reducing vibration and impact. Multiple guide vane assemblies have their slide tables connected to the same lead screw, enabling synchronous movement of all assemblies and ensuring coordination and consistency during replacement. The lead screw drive has excellent self-locking characteristics; when the second motor stops, the guide vane assembly remains stably in the designated position without the need for additional braking devices, improving system safety. The lead screw drive structure is compact and highly efficient, effectively converting the rotational motion of the second motor into linear motion of the guide vane assembly, reducing energy consumption. The drive assembly is mounted integrally on the bracket, with a clear structure, facilitating daily maintenance and troubleshooting, and extending equipment lifespan.

[0015] As a preferred embodiment of the present invention, a sealing ring is connected to the sealing surface of the deflector assembly that connects to the rear compartment and / or the sealing surface of the rear compartment that connects to the deflector assembly.

[0016] This structural design, with a sealing ring installed on the mating sealing surface of the baffle assembly and the rear compartment, effectively prevents gas leakage and ensures the stability of the internal pressure environment of the autoclave. The excellent sealing effect maintains the constant pressure and temperature conditions required for the hot pressing process, avoiding process parameter fluctuations caused by leakage and improving product quality consistency. The sealing ring can compensate for minor gaps or unevenness between the mating surfaces of the baffle assembly and the rear compartment, adapting to changes in thermal expansion and contraction under different operating conditions and maintaining a continuous and reliable sealing effect. By preventing media leakage, it reduces corrosion or contamination of other equipment components, lowers maintenance frequency, and extends the overall service life of the autoclave. The sealing ring can be installed on the sealing surface of the baffle assembly and / or the sealing surface of the rear compartment, providing multiple installation options for easy configuration and replacement according to actual needs. As a consumable part, the sealing ring can be replaced individually without disassembling the entire baffle assembly or the rear compartment structure, making maintenance convenient and reducing costs.

[0017] Secondly, the present invention also provides a method for replacing the guide vane of an autoclave, utilizing the apparatus for replacing the guide vane of an autoclave as described in any of the preceding claims, the method comprising the following steps: S1. Activate the partition system to seal and separate the front cabin and the rear cabin; S2. Depressurize the rear compartment; S3. Start the replacement system; when the replacement system is connected to one of the deflector assemblies, the replacement system removes the deflector assembly sealed to the rear compartment from the autoclave, replaces the deflector with the deflector, and then the replacement system moves the deflector assembly to the autoclave and seals it with the rear compartment; when the replacement system is connected to at least two deflector assemblies, the replacement system removes the deflector assembly sealed to the rear compartment from the autoclave and moves another deflector assembly to the autoclave and seals it with the rear compartment.

[0018] The method for replacing guide vanes in an autoclave, as described in this invention, involves separating the front and rear compartments using a partition system. The guide vane assembly connected to the rear compartment is replaced using a replacement system, allowing for the replacement of different guide vanes. During this process, the workpiece in the front compartment remains in the same environment. After the guide vane is replaced, the rear compartment is resealed, and the rear compartment is heated and pressurized to the conditions of the front compartment. The partition system then connects the front and rear compartments, allowing the process to continue using the replaced guide vane. The thermal history of the workpiece remains uninterrupted. The processing results of the same batch of workpieces under different guide vane conditions are compared under identical thermal history benchmarks, demonstrating excellent reliability and repeatability of the process data. Simultaneously, the method automates the loading and unloading of the guide vane assembly relative to the rear compartment. Only operators are required to load and unload the guide vanes from the assembly; no personnel are needed to enter the compartment, reducing safety and quality risks, improving assembly efficiency, and meeting the requirements for high-frequency, multi-condition, and rapid switching. This method is simple, convenient, and effective.

[0019] As a preferred embodiment of the present invention, the method for replacing the guide plate of the autoclave further includes: S4. Pressurize and adjust the temperature of the rear compartment until the absolute value of the pressure difference between the front and rear compartments is lower than or equal to the set pressure threshold, and the absolute value of the temperature difference between the front and rear compartments is lower than or equal to the set temperature threshold. S5. Activate the partition system to connect the front cabin and the rear cabin.

[0020] Using this method, the pressure and temperature of the rear chamber can be restored to be consistent with those of the front chamber. This ensures that after the isolation system connects the front and rear chambers, the pressure and temperature in the autoclave will not change significantly, thereby avoiding alterations to the thermal history of the same batch of workpieces and reducing the reliability and repeatability of process data.

[0021] Thirdly, the present invention also provides an autoclave, including an autoclave body and a device for replacing the autoclave baffle as described in any of the above, wherein the front compartment is used to place the workpiece.

[0022] The autoclave described in this invention connects or isolates the front and rear compartments via a partition system. In the isolated state, the guide vane assembly connected to the rear compartment can be replaced via a replacement system, allowing for the replacement of different guide vanes. The workpiece in the front compartment remains in the same environment. After the guide vane is replaced, the rear compartment is resealed, and the rear compartment is heated and pressurized to the conditions of the front compartment. The partition system then connects the front and rear compartments, and the process continues using the replaced guide vane. The thermal history of the workpiece is uninterrupted. The processing results of the same batch of workpieces under different guide vane conditions are compared under identical thermal history benchmarks, demonstrating excellent reliability and repeatability of the process data. Simultaneously, the autoclave automates the entry and exit of the guide vane assembly relative to the rear compartment. Only operators need to load and unload the guide vanes on the assembly; no personnel need to enter the compartment, reducing safety and quality risks, improving assembly efficiency, and meeting the requirements for high-frequency, multi-condition rapid switching. This autoclave has a simple structure, is easy to use, and performs well.

[0023] As a preferred embodiment of the present invention, the rear compartment includes a rear end door and a rear compartment body, the baffle assembly is sealed between the rear end door and the rear compartment body, the rear end door is connected to a fan; and / or, a heating plate is provided inside the autoclave.

[0024] With this structural design, the baffle assembly is sealed between the rear end door and the rear compartment body, forming a detachable modular sealing unit that facilitates individual maintenance and replacement, improving equipment maintainability. The rear end door connects to the fan, and together with the baffle, effectively arranges the airflow pattern inside the autoclave, ensuring heat distribution according to the design, and improving the controllability and efficiency of the autoclaving process. The rear end door and the rear compartment body are sealed together by the baffle assembly, and together with the partition system, they connect to the autoclave body. The fan speed can be precisely controlled to adjust the airflow within the autoclave, meeting the thermal distribution requirements of different process stages. The autoclave body... The internal heating plate directly heats the space inside the tank, resulting in rapid heating, high thermal efficiency, and a shortened process cycle. The heating plate, along with the fan and the guide vane assembly, works in tandem to form a forced convection heating system, effectively eliminating temperature dead zones and ensuring uniform heating of the workpiece. The rear door integrates the fan, and the guide vane assembly serves as a dual-function component for sealing and guiding flow, resulting in a compact overall structure and high space utilization. This structure meets the requirements of high-temperature, high-pressure hot pressing processes and can adapt to the processing needs of workpieces of different materials and sizes, exhibiting good versatility. Precise temperature and airflow control reduces heat loss, lowers energy consumption, and improves the economic efficiency of equipment operation.

[0025] As a further preferred embodiment of the present invention, the autoclave further includes a pressure control component, a sensor component, and a control system; the pressure control component is connected to the front chamber and the rear chamber respectively, and is used for pressurizing or depressurizing the front chamber and the rear chamber; the sensor component is connected to the front chamber and the rear chamber respectively, and is used for detecting the pressure and temperature of the front chamber and the pressure and temperature of the rear chamber; the control system is electrically connected to the pressure control component, the sensor component, the fan, the heating plate, the partition system, and the replacement system.

[0026] With this structural configuration, the pressure control components are connected to the front chamber and the rear chamber respectively, enabling independent pressurization and depressurization control. This allows for separate control of maintaining the operating conditions in the front chamber and replacing the guide vanes in the rear chamber, ensuring a constant thermal history of the workpiece. The sensor components monitor the pressure and temperature parameters of the front and rear chambers in real time, providing real-time and accurate data support to the control system and ensuring precise control of process parameters. The control system coordinates the pressure control components, sensor components, fan, heating plate, isolation system, and replacement system to achieve intelligent integrated management of the entire equipment. Through multi-system linkage control, the pressure and temperature within the autoclave can be precisely adjusted. By optimizing parameters such as airflow, the hot pressing process is improved, enhancing product quality consistency. Real-time monitoring and automatic control functions can promptly detect anomalies and take corresponding measures, effectively preventing safety hazards such as overpressure and overtemperature. The centralized control system simplifies the operation process, reduces manual intervention, and lowers operational difficulty and labor intensity. Precise pressure and temperature control avoids energy waste and improves the economic efficiency of equipment operation. The control system can record various parameters during the process, facilitating process optimization and quality traceability. The sensor components can monitor the equipment's operating status in real time, promptly detecting potential faults and improving equipment reliability. The control system can flexibly adjust process parameters to adapt to the hot pressing process requirements of different materials and product specifications.

[0027] As a further preferred technical solution of the present invention, the pressure control component includes an air compressor, a vacuum pump, a pressure relief valve, and a solenoid valve; at least one solenoid valve is connected to the front compartment and the rear compartment respectively; the air compressor is connected to the solenoid valve, and the air compressor pressurizes the autoclave through the solenoid valve; the vacuum pump is connected to the solenoid valve, and the vacuum pump evacuates the autoclave through the solenoid valve; the pressure relief valve is used to depressurize the autoclave; that is, before the partition system separates the front compartment and the rear compartment, the pressure control component can pressurize and depressurize the entire autoclave; after the partition system separates the front compartment and the rear compartment, the pressure control component can pressurize and depressurize the front compartment separately, and pressurize and depressurize the rear compartment separately.

[0028] This structural configuration, combining the air compressor, vacuum pump, pressure relief valve, and solenoid valve, achieves bidirectional control of pressurization and depressurization, meeting the complete pressure control requirements of the hot pressing process. Precise control of the solenoid valve and pressure relief valve allows for pressurization and depressurization of the autoclave, offering a wide pressure adjustment range and fast response. After the partition system is operational, independent pressurization and depressurization control can be applied to the front and rear chambers, meeting the differentiated pressure requirements of different process stages. Before the partition system operates, unified pressure control of the entire autoclave is possible; after partitioning, independent control of each zone is achieved, improving the equipment's process adaptability. The precise control of the solenoid valve, in conjunction with the air compressor and vacuum pump, enables bidirectional control of the pressure relief valve. The air pump enables precise pressure regulation, ensuring the accuracy of process parameters. The air compressor and the pressure relief valve are responsible for pressurization and depressurization respectively, avoiding the limitation of bidirectional operation of a single device and improving the efficiency of pressure regulation. The configuration of multiple solenoid valves provides redundancy, so even if one solenoid valve fails, the system can still maintain basic functions, improving equipment reliability. Precise control of the solenoid valves avoids unnecessary gas waste and reduces the operating energy consumption of the air compressor and the vacuum pump. The pressure parameters of the front chamber and the rear chamber can be flexibly adjusted according to different materials and process requirements, adapting to various hot pressing process needs. The rapid response capability of the solenoid valves allows for quick pressure regulation in emergency situations, improving the safety of equipment operation.

[0029] As a further preferred embodiment of the present invention, the sensor assembly includes a pressure sensor and a temperature sensor; at least one pressure sensor is connected to the front cabin and the rear cabin respectively, and the pressure sensor is used to detect the pressure in the front cabin and the rear cabin; at least one temperature sensor is connected to the front cabin and the rear cabin respectively, and the temperature sensor is used to detect the temperature in the front cabin and the rear cabin.

[0030] With this structural configuration, the front and rear compartments are each equipped with independent pressure and temperature sensors, enabling precise monitoring of parameters in each compartment and avoiding data confusion. The sensor assembly collects pressure and temperature data in real time, providing immediate feedback to the control system and ensuring precise control of process parameters. Through precise zonal monitoring data, the pressure and temperature curves of the hot-pressing process can be optimized, improving product quality consistency. Real-time monitoring of pressure and temperature changes in each compartment can promptly detect abnormalities such as overpressure and overtemperature, triggering safety protection mechanisms. Abnormal changes in sensor data can serve as early warning signals for equipment failures, facilitating timely maintenance and handling. Each compartment is equipped with at least one sensor, providing basic redundancy protection and improving system reliability.

[0031] As a further preferred technical solution of the present invention, a plurality of the temperature sensors are distributed at intervals along the axial direction of the autoclave.

[0032] With this structural arrangement, since the fan is located at one end of the axial direction of the autoclave, the airflow inside the autoclave blows from one end to the other. Through several temperature sensors that are spaced apart along the axial direction of the autoclave, the temperature gradient of the airflow inside the autoclave can be collected in real time and fed back to the control system. The control system dynamically adjusts the fan speed and the power of the heating plate according to the temperature gradient deviation, thereby realizing the coordinated closed-loop control of the temperature field and the flow field inside the autoclave.

[0033] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: This invention discloses an apparatus and method for replacing guide vanes in an autoclave. The autoclave connects or disconnects the front and rear compartments via a partition system. In the disconnected state, the guide vane assembly connected to the rear compartment can be replaced via a replacement system, thus enabling the replacement of different guide vanes. During this process, the environment of the workpiece placed in the front compartment remains unchanged. After the guide vane is replaced, the rear compartment is resealed, and the rear compartment is heated and pressurized to the operating conditions of the front compartment. The partition system then connects the front and rear compartments, and the process continues using the replaced guide vane. The workpiece's thermal... The process is uninterrupted, and the processing results of the same batch of workpieces under different deflector conditions are compared under the same thermal history benchmark. The reliability and repeatability of the process data are excellent. At the same time, the deflector assembly is automated for entering and exiting the rear compartment. Only the deflectors on the deflector assembly need to be loaded and unloaded by the operator, without the need for personnel to enter the compartment, reducing safety and quality risks, improving assembly efficiency, and meeting the requirements of high frequency and rapid switching of multiple working conditions. The device and autoclave have a simple structure and are easy to use. The method is simple in steps, easy to operate, and has good results. Attached Figure Description

Detailed Implementation

[0036] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0037] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of the present invention is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the present invention or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a particular device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on the present invention.

[0038] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but that it can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0039] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0040] Furthermore, in the description of the embodiments of the present invention, "several", "more than", and "a number of" represent at least two. The number can be any number, such as 2, 3, 4, 5, 6, 7, 8, or 9, and can even exceed nine.

[0041] Furthermore, in the description of the technical solution of this invention, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0042] In related technologies, existing autoclaves suffer from the following main problems: First, the fixed installation of the guide vanes results in a single flow field pattern, which cannot meet the requirements for switching flow fields under multiple operating conditions; second, replacing the guide vanes requires stopping the machine to depressurize and interrupt the thermal process, leading to low efficiency and poor comparability of process data; third, the plate replacement process relies on manual operation, resulting in low automation and difficulty in guaranteeing positioning accuracy and sealing reliability. These problems restrict the autoclave's adaptability and efficiency under multiple operating conditions in composite material process research. Therefore, the technical solution of this application was developed, which is described below in conjunction with... Figures 1 to 8 To elaborate.

[0043] Example 1 like Figures 1 to 7 As shown, the device for replacing the guide plate of an autoclave according to the present invention includes an isolation system 6 and a replacement system 2.

[0044] like Figures 1 to 3 , Figure 6 As shown, the partition system 6 is used to connect to the autoclave 1, which includes a front compartment and a rear compartment. The partition system 6 is used to provide either a conductive or sealed partition between the front compartment and the rear compartment.

[0045] like Figures 1 to 5 As shown, the replacement system 2 is used to connect to the autoclave 1, and the replacement system 2 is connected to at least one baffle assembly 13, each of the baffle assemblies 13 including a baffle 131.

[0046] (Not shown) When the replacement system 2 is connected to one of the deflector assemblies 13, the deflector assembly 13 is used for a sealed connection to the rear compartment. The replacement system 2 can move the deflector assembly 13 out relative to the autoclave 1. After replacing the deflector 131 with a different opening shape, opening ratio, pore diameter and / or pore distribution, the replacement system 2 can move the deflector assembly 13 into the autoclave 1 and seal the connection.

[0047] like Figure 4 and Figure 5 As shown, when the replacement system 2 connects at least two of the deflector assemblies 13, the opening shape, opening ratio, pore diameter, and / or pore distribution on each deflector 131 are different (e.g., Figure 4 and Figure 5 In the process, the openings on the two guide vanes 131 are circular and square, respectively, with different opening sizes and opening ratios (one is axially symmetrically distributed, and the other is uniformly distributed in an array). One of the guide vane assemblies 13 is used for a sealed connection to the rear compartment. The replacement system 2 can move one guide vane assembly 13 out relative to the autoclave 1 and move the other guide vane assembly 13 into the autoclave 1 and seal the connection. Figures 1 to 5The example illustrates the case where the replacement system 2 connects two of the deflector assemblies 13.

[0048] In some alternative implementations, such as Figure 6 As shown, the partition system 6 includes a partition plate 61, a valve body 62, and a first motor 63; the shape of the partition plate 61 matches the inner edge shape of the autoclave 1, the partition plate 61 is rotatably connected to the separation between the front compartment and the rear compartment inside the autoclave 1, and a sealing ring is connected to the outer edge of the partition plate 61 and / or the inner edge of the separation; the valve body 62 is connected to the autoclave 1 and the partition plate 61; the first motor 63 is located outside the autoclave 1, the first motor 63 is connected to the valve body 62, and the first motor 63 drives the partition plate 61 to rotate through the valve body 62. With this structural design, the shape of the partition plate 61 matches the inner edge shape of the autoclave 1, ensuring that the partition plate 61 fits tightly against the interior of the autoclave and effectively separates the front compartment and the rear compartment. A sealing ring is provided on the outer edge of the partition plate 61 and / or the inner edge of the separation point, enhancing the airtightness of the separation and preventing cross-contamination or leakage of media between compartments, thus improving process control accuracy and safety. The first motor 63, located outside the autoclave 1, drives the partition plate 61 to rotate via the valve body 62, achieving automatic control of the opening and closing of the partition plate 61, improving operational convenience and system integration. The first motor 63 is positioned outside the autoclave, avoiding the influence of harsh operating conditions such as high temperature and high pressure, which is beneficial for equipment maintenance and extends its service life, offering convenient maintenance and high reliability. The partition system 6 integrates the partition plate 61, the valve body 62, and the first motor 63, featuring a compact structure, high functional integration, and stable collaborative operation, suitable for autoclaving processes requiring precise control of compartment isolation. In one specific embodiment, the valve body 62 can be a butterfly valve.

[0049] In some alternative implementations, such as Figures 1 to 5As shown, the replacement system 2 includes a bracket, a drive assembly, a slide table 23, and a slide rail 24; the bracket spans the rear compartment, and the upper and lower parts of the bracket are respectively connected to the slide rail 24, with the autoclave 1 located between two slide rails 24; the top and bottom of each deflector assembly 13 are respectively connected to the slide table 23, and the slide table 23 is slidably connected to the corresponding slide rail 24; the drive assembly is connected to the bracket, and the drive assembly drives each deflector assembly 13 to slide along the slide rail 24 closer to or away from the rear compartment. With this structural arrangement, the slide table 23 and the slide rail 24 cooperate to allow the deflector assembly 13 to slide in and out of the rear compartment along the bracket, enabling rapid installation, disassembly, or replacement, significantly improving maintenance and operational efficiency. The bracket spans the rear compartment and is equipped with slide rails 24 at both the top and bottom. The autoclave 1 is located between the two slide rails 24, forming a symmetrical support structure, enhancing overall rigidity and operational stability, and ensuring the alignment and safety of the deflector assembly 13 during movement. The drive assembly is integrated into the bracket and can automatically drive the... The guide vane assembly 13 slides along the slide rail 24 to achieve automated control, reduce manual intervention, and improve the system's automation level. The slide rail 24 is arranged perpendicular to the axis of the autoclave 1, making full use of the external space of the autoclave 1 and avoiding interference with the internal process area of ​​the autoclave 1. It also facilitates equipment maintenance and expansion. The replacement system 2 can replace guide vanes 131 of various specifications by removing and inserting them into the autoclave. It has good versatility and adaptability and can be widely used in autoclave equipment under different working conditions.

[0050] In some alternative implementations, such as Figures 1 to 5As shown, the drive assembly includes a second motor 21 and a lead screw 22; the lead screw 22 is rotatably connected to the bracket, and the lead screw 22 is arranged parallel to the slide rail 24; the slide table 23 at the top of each of the guide plate assemblies 13 is threaded to the lead screw 22, or the slide table 23 at the bottom of each of the guide plate assemblies 13 is threaded to the lead screw 22; the second motor 21 is connected to the bracket, and the second motor 21 connects to and drives the lead screw 22 to rotate. With this structural design and the use of the lead screw 22 for transmission, the second motor 21 drives the lead screw 22 to rotate, enabling precise position adjustment of the guide vane assembly 13 along the slide rail 24, thus meeting the precise positioning requirements for replacing the guide vane 131. The lead screw 22 is parallel to the slide rail 24, and the slide table 23 is threadedly connected to the lead screw 22, forming a stable transmission pair. This ensures smooth operation of the guide vane assembly 13 during movement, reducing vibration and impact. Since the slide tables 23 of multiple guide vane assemblies 13 are all connected to the same lead screw 22, all of them can achieve precise positioning adjustment. The synchronous movement of the guide vane assembly 13 ensures coordination and consistency during the replacement process. The lead screw 22 transmission has excellent self-locking characteristics; when the second motor 21 stops working, the guide vane assembly 13 can stably remain in the designated position without the need for an additional braking device, improving system safety. The lead screw 22 transmission structure is compact and has high transmission efficiency, efficiently converting the rotational motion of the second motor 21 into the linear motion of the guide vane assembly 13, reducing energy consumption. The drive assembly is mounted as a whole on the bracket, with a clear structure, facilitating daily maintenance and troubleshooting, and extending the equipment's service life. In some optional embodiments, the second motor 21 is connected to a reducer, the reducer is connected to a coupling, and the coupling is connected to the lead screw 22.

[0051] As an example, such as Figure 1 , Figure 4 and Figure 5As shown, in this embodiment, several installation positions of the guide vane assemblies 13 are spaced apart along the length of the lead screw 22. These installation positions can be equally spaced or unequally spaced. One installation position coincides with the position of the autoclave 1 and is the working position; the remaining installation positions are spare positions. All the guide vane assemblies 13 are installed at their respective installation positions and driven by the same lead screw 22, achieving a match between the spacing of each guide vane assembly 13 and the switching stroke. After the lead screw 22 drives each guide vane assembly 13 to move synchronously for one switching stroke, the working position... The guide vane assembly 13 moves laterally out of the autoclave 1, and the guide vane assembly 13 at the standby position adjacent to the working position moves laterally into the autoclave 1, forming a new flow field scheme within the autoclave 1. When the installation positions are set at equal intervals, all the switching strokes are the same. When the installation positions are set at unequal intervals, each switching stroke is pre-input into the controller of the lead screw 22 according to the spacing set at the installation position, so as to achieve precise matching between the switching stroke and the spacing set at the installation position, thereby achieving precise switching of the guide vane assembly 13. Generally speaking, the scheme of setting the installation positions at equal intervals is preferred.

[0052] In some alternative embodiments, a sealing ring is connected to the sealing surface of the deflector assembly 13 that abuts the rear compartment and / or the sealing surface of the rear compartment that abuts the deflector assembly 13. This structural design, with a sealing ring installed on the mating sealing surface of the baffle assembly 13 and the rear compartment, effectively prevents gas leakage and ensures the stability of the internal pressure environment of the autoclave. The excellent sealing effect maintains the constant pressure and temperature conditions required for the hot pressing process, avoiding fluctuations in process parameters due to leakage and improving product quality consistency. The sealing ring can compensate for minor gaps or unevenness between the baffle assembly 13 and the rear compartment mating surface, adapting to changes in thermal expansion and contraction under different operating conditions and maintaining a continuous and reliable sealing effect. By preventing media leakage, it reduces corrosion or contamination of other equipment components, lowers maintenance frequency, and extends the overall service life of the autoclave. The sealing ring can be installed on the sealing surface of the baffle assembly 13 and / or the sealing surface of the rear compartment, providing multiple installation options for easy configuration and replacement according to actual needs. As a consumable part, the sealing ring can be replaced individually without disassembling the entire baffle assembly 13 or the rear compartment structure, making maintenance convenient and reducing costs.

[0053] The sealing ring can adopt the sealing ring structure in the existing technology.

[0054] This embodiment describes a device for replacing the baffle plate of an autoclave. The isolation system 6 connects or disconnects the front and rear compartments. When disconnected, the baffle plate assembly 13 connected to the rear compartment can be replaced via the replacement system 2, allowing for the replacement of different baffle plates 131. The environment of the workpiece placed in the front compartment remains unchanged. After the baffle plate 131 is replaced, the rear compartment is resealed, and the rear compartment is heated and pressurized to the operating conditions of the front compartment. The isolation system 6 then connects the front and rear compartments, and the process continues using the replaced baffle plate 131. The process ensures uninterrupted thermal history of the workpiece. The processing results of the same batch of workpieces under different conditions with different guide vanes 131 are compared under identical thermal history benchmarks, demonstrating excellent reliability and repeatability of the process data. Simultaneously, it automates the entry and exit of the guide vane assembly 13 relative to the rear cabin. Only operators need to load and unload the guide vanes 131 on the guide vane assembly 13; no personnel need to enter the cabin, reducing safety and quality risks, improving assembly efficiency, and meeting the requirements for high-frequency, multi-condition, and rapid switching. The device has a simple structure, is easy to use, and performs well.

[0055] Example 2 like Figures 1 to 7 As shown, the present invention provides a method for replacing the guide vane of an autoclave, utilizing the apparatus for replacing the guide vane of an autoclave as described in Example 1. The method includes the following steps: S1. Start the first motor 63 of the isolation system 6. The first motor 63 drives the partition plate 61 to rotate through the valve body 62. The outer edge of the partition plate 61 is attached to the inner edge of the autoclave 1, and the sealing ring at the outer edge of the partition plate 61 and / or the inner edge of the separation between the front compartment and the rear compartment is deformed, thereby sealing and isolating the front compartment and the rear compartment, thereby cutting off the air passage between the front compartment and the rear compartment, and the pressure of the front compartment and the rear compartment is independent of each other.

[0056] S2. Depressurize the rear compartment to reduce it to atmospheric pressure.

[0057] S3. Start the second motor 21 of the replacement system 2. The second motor 21 drives the lead screw 22 to rotate, thereby driving the slide table 23 to slide along the slide rail 24.

[0058] Not shown, when the replacement system 2 is connected to one of the deflector assemblies 13, the slide table 23 slides along the slide rail 24, causing the deflector assembly 13, which is sealed to the rear compartment, to move out of the autoclave 1. At this time, the operator can replace the deflector 131 with the deflector assembly 13. Then, the second motor 21 reverses and moves the deflector assembly 13 to the autoclave 1. The sealing ring on the sealing surface of the deflector assembly 13 that is connected to the rear compartment and / or the sealing surface of the rear compartment that is connected to the deflector assembly 13 is squeezed and deformed, so as to achieve a sealed connection between the deflector assembly 13 and the rear compartment.

[0059] like Figures 1 to 5 As shown, when the replacement system 2 connects at least two of the deflector assemblies 13, the rotation of the lead screw 22 drives all the slides 23 to move. The slides 23 slide along the slide rail 24, causing the deflector assembly 13 sealed to the rear compartment to move out of the autoclave 1, and simultaneously moving the other deflector assembly 13 to the autoclave 1. The sealing rings provided on the sealing surface of the deflector assembly 13 that abuts the rear compartment and / or the sealing surface of the rear compartment that abuts the deflector assembly 13 are squeezed and deformed, thereby achieving a sealed connection between the deflector assembly 13 and the rear compartment.

[0060] S4. Pressurize and adjust the temperature of the rear compartment until the absolute value of the pressure difference between the front and rear compartments is lower than or equal to the set pressure threshold, and the absolute value of the temperature difference between the front and rear compartments is lower than or equal to the set temperature threshold.

[0061] S5. Start the first motor 63. The first motor 63 drives the partition plate 61 to rotate through the valve body 62, thereby connecting the front cabin and the rear cabin.

[0062] This embodiment describes a method for replacing the guide vane in an autoclave. The isolation system 6 separates the front and rear compartments. The replacement system 2 replaces the guide vane assembly 13 connected to the rear compartment, thus allowing for the replacement of different guide vanes 131. During this process, the environment of the workpiece placed in the front compartment remains unchanged. After the guide vane 131 is replaced, the rear compartment is resealed, and the rear compartment is heated and pressurized to the conditions of the front compartment. The isolation system 6 then connects the front and rear compartments, allowing the process to continue using the replaced guide vane 131. The thermal history of the workpiece remains uninterrupted. Throughout the entire process, the processing results of the same batch of workpieces under different guide vane 131 conditions are based on the same thermal history baseline. In comparison, the reliability and repeatability of the process data are excellent. Simultaneously, the automated entry and exit of the guide vane assembly 13 relative to the rear compartment is achieved. Only the guide vane 131 on the guide vane assembly 13 needs to be loaded and unloaded by operators; no personnel need to enter the compartment, reducing safety and quality risks, improving assembly efficiency, and meeting the requirements for high-frequency, multi-condition rapid switching. The pressure and temperature of the rear compartment can be restored to be consistent with the front compartment, ensuring that after the partition system 6 connects the front and rear compartments, the pressure and temperature in the autoclave 1 do not change significantly, thus altering the thermal history of the same batch of workpieces and causing deviations in the reliability and repeatability of the process data. This method is simple, convenient to operate, and effective.

[0063] Example 3 like Figures 1 to 8 As shown, the autoclave of the present invention includes an autoclave body 1 and a device for replacing the autoclave baffle as described in Example 1, wherein the front compartment is used to place the workpiece.

[0064] In some alternative implementations, such as Figure 1 and Figure 3As shown, the rear compartment includes a rear door 11 and a rear compartment body. The baffle assembly 13 is sealed between the rear door 11 and the rear compartment body. The rear door 11 is connected to a fan 12; and / or, a heating plate 17 is provided inside the autoclave 1. With this structural arrangement, the baffle assembly 13 is sealed between the rear door 11 and the rear compartment body, forming a detachable modular sealing unit, facilitating individual maintenance and replacement, and improving equipment maintainability. The rear door 11 is connected to the fan 12, and together with the baffle 131, it can effectively arrange the airflow pattern inside the autoclave, ensuring heat distribution according to the design, and improving the controllability and efficiency of the hot pressing process. The rear door 11 and the rear compartment body are sealed together through the baffle assembly 13, and together with the partition system 6, they connect to the autoclave 1. The fan 12 speed can be configured to precisely control the airflow size in the autoclave 1, meeting the thermal distribution requirements of different process stages. The heating plate 17 is installed inside the pressure tank 1, which can directly heat the space inside the tank, resulting in rapid heating, high thermal efficiency, and shortened process cycle. The heating plate 17 works in conjunction with the fan 12 and the guide plate assembly 13 to form a forced convection heating system, effectively eliminating temperature dead zones and ensuring uniform heating of the workpiece. The rear door 11 integrates the fan 12, and the guide plate assembly 13 serves as a dual-function component for sealing and guiding, resulting in a compact overall structure and high space utilization. This structure can meet the requirements of high-temperature and high-pressure hot pressing processes and adapt to the processing needs of workpieces of different materials and sizes, exhibiting good versatility. Through precise temperature and airflow control, heat loss is reduced, energy consumption is lowered, and the economic efficiency of equipment operation is improved.

[0065] In some alternative embodiments, the rear door 11 and the rear cabin body are kept relatively fixed by a support frame. Figure 1 (The support frame is not shown in the diagram). The support frame forms a space between the rear door 11 and the rear cabin body for the replacement system 2 and the deflector assembly 13 to pass through, that is, the support frame does not intrude on the movement path of the deflector assembly 13 along the replacement system 2.

[0066] In some alternative embodiments, the fan 12 includes rotating blades and a third motor. The rotating blades are connected to the inside of the rear door 11, and the third motor is connected to the outside of the rear door 11. The rotating blades are connected to the third motor through a magnetic coupling drive mechanism to realize power transmission and pressure sealing between the inside and outside of the tank, making it less likely to cause pressure leakage.

[0067] In some optional embodiments, the autoclave further includes a pressure control assembly, a sensor assembly, and a control system 4; the pressure control assembly is connected to the front compartment and the rear compartment respectively, and is used for pressurizing or depressurizing the front compartment and the rear compartment; the sensor assembly is connected to the front compartment and the rear compartment respectively, and is used for detecting the pressure and temperature of the front compartment and the pressure and temperature of the rear compartment; the control system 4 is electrically connected to the pressure control assembly, the sensor assembly, the fan 12, the heating plate 17, the partition system 6, and the replacement system 2. With this structural configuration, the pressure control components are connected to the front chamber and the rear chamber respectively, enabling independent pressurization and depressurization control. This allows for separate control of maintaining the operating conditions of the front chamber and replacing the guide vane 131 in the rear chamber, ensuring a constant thermal history of the workpiece. The sensor components monitor the pressure and temperature parameters of the front and rear chambers in real time, providing real-time and accurate data support to the control system 4, ensuring precise control of process parameters. The control system 4 coordinates the pressure control components, sensor components, fan 12, heating plate 17, partition system 6, and replacement system 2, achieving intelligent integrated management of the entire equipment. Through multi-system linkage control, the pressure inside the autoclave can be precisely adjusted. The system optimizes the hot pressing process by controlling parameters such as force, temperature, and airflow, improving product quality consistency. Real-time monitoring and automatic control functions can promptly detect abnormalities and take corresponding measures, effectively preventing safety hazards such as overpressure and overtemperature. The centralized control system simplifies the operation process, reduces manual intervention, and lowers operational difficulty and labor intensity. Precise pressure and temperature control avoids energy waste and improves the economic efficiency of equipment operation. The control system 4 can record various parameters in the process, facilitating process optimization and quality traceability. The sensor components can monitor the equipment's operating status in real time, promptly detect potential faults, and improve equipment reliability. The control system 4 can flexibly adjust process parameters to adapt to the hot pressing process requirements of different materials and product specifications.

[0068] In some alternative implementations, the control system 4 is a PLC or an industrial computer.

[0069] In some alternative implementations, such as Figures 1 to 3As shown, the pressure control assembly includes an air compressor 3, a vacuum pump 5, a pressure relief valve, and a solenoid valve 8; at least one solenoid valve 8 is connected to the front compartment and the rear compartment respectively; the air compressor 3 is connected to the solenoid valve 8, and the air compressor 3 pressurizes the autoclave 1 through the solenoid valve 8; the vacuum pump 5 is connected to the solenoid valve 8, and the vacuum pump 5 evacuates the autoclave 1 through the solenoid valve 8; the pressure relief valve is used to depressurize the autoclave 1; that is, before the partition system 6 separates the front compartment and the rear compartment, the pressure control assembly can pressurize and depressurize the entire autoclave 1; after the partition system 6 separates the front compartment and the rear compartment, the pressure control assembly can pressurize and depressurize the front compartment separately, and pressurize and depressurize the rear compartment separately. With this structural configuration, the combination of the air compressor 3, the vacuum pump 5, the pressure relief valve, and the solenoid valve 8 achieves bidirectional control of pressurization and depressurization, meeting the complete pressure control requirements of the hot pressing process. Through precise control of the solenoid valve 8 and the pressure relief valve, the hot pressurization tank 1 can be pressurized and depressurized, with a wide pressure adjustment range and fast response speed. After the partition system 6 is operational, the front chamber and the rear chamber can be independently pressurized and depressurized to meet the differentiated pressure requirements of different process stages. Before the partition system 6 is operational, the entire hot pressurization tank 1 can be under unified pressure control; after partitioning, independent control of each zone can be achieved, improving the equipment's process adaptability. The precise control of the solenoid valve 8, in conjunction with the air compressor 3 and the vacuum pump 5, allows for bidirectional control of the entire hot pressurization tank 1, meeting the differentiated pressure requirements of different process stages. The vacuum pump 5 enables precise pressure regulation, ensuring the accuracy of process parameters. The air compressor 3 and the pressure relief valve are responsible for pressurization and depressurization respectively, avoiding the bidirectional operation limitation of a single device and improving the efficiency of pressure regulation. The configuration of multiple solenoid valves 8 provides redundancy, ensuring the system maintains basic functions even if one solenoid valve 8 fails, thus improving equipment reliability. Precise control of the solenoid valves 8 avoids unnecessary gas waste and reduces the operating energy consumption of the air compressor 3 and the vacuum pump 5. The pressure parameters of the front and rear chambers can be flexibly adjusted according to different materials and process requirements, adapting to various hot-pressing process needs. The rapid response capability of the solenoid valves 8 allows for quick pressure regulation in emergency situations, improving the safety of equipment operation.

[0070] In some alternative implementations, such as Figure 7 As shown, the electromagnetic valve 8 includes an actuator 81 and a solenoid valve 82. The control system 4 controls the operation of the solenoid valve 82, and the solenoid valve 82 controls the supply or exhaust of air to the actuator 81. The actuator 81 drives the valve core or valve plate to operate, so as to realize the opening or closing of the air circuit.

[0071] In some alternative implementations, such as Figures 1 to 3 As shown, the sensor assembly includes a pressure sensor 7 and a temperature sensor 9. At least one pressure sensor 7 is connected to each of the front and rear compartments, and the pressure sensor 7 is used to detect the pressure in the front and rear compartments respectively. At least one temperature sensor 9 is connected to each of the front and rear compartments, and the temperature sensor 9 is used to detect the temperature in the front and rear compartments respectively. With this structural arrangement, the front and rear compartments are each equipped with independent pressure sensors 7 and temperature sensors 9, enabling precise monitoring of parameters in each compartment and avoiding data confusion. The sensor assembly collects pressure and temperature data in real time, providing immediate feedback to the control system 4 to ensure precise control of process parameters. Through precise zonal monitoring data, the pressure and temperature curves of the hot-pressing process can be optimized, improving product quality consistency. Real-time monitoring of pressure and temperature changes in each compartment can promptly detect abnormalities such as overpressure and overtemperature, triggering safety protection mechanisms. Abnormal changes in sensor data can serve as early warning signals for equipment failures, facilitating timely maintenance and handling. Each compartment is equipped with at least one sensor, providing basic redundancy protection and improving system reliability.

[0072] In some alternative embodiments, a high-pressure wire-sealed connector is connected to the wall of the autoclave 1, and the signal cable of the sensor assembly passes through the high-pressure wire-sealed connector, passes through the autoclave 1, and is connected to the control system 4.

[0073] In some optional embodiments, the control system 4, the pressure control component, and the pressure sensor 7 form a pressure closed-loop control circuit. During the pressure replenishment process of the baffle assembly 13, the air compressor 3 pressurizes the rear compartment through the solenoid valve 8. The control system 4 continuously monitors the pressure data of the front compartment and the rear compartment through the pressure sensor 7. When the absolute value of the pressure difference between the front compartment and the rear compartment is lower than or equal to the set pressure threshold, the control system 4 automatically controls the solenoid valve 8 to close and instructs the isolation system 6 to open, connecting the front compartment and the rear compartment, thereby realizing the automated control of the pressurization process.

[0074] In some alternative implementations, such as Figure 6 As shown, the heating plate 17 adopts a heating fin structure, with a plurality of heating fins arranged around the inner tank 14 to heat the airflow inside the tank. The power of the heating fins is adjusted by the control system 4 according to the real-time feedback data of the temperature sensor 9 in a closed-loop temperature regulation. When the absolute value of the temperature difference between the front compartment and the rear compartment is lower than or equal to the set temperature threshold, the control system 4 automatically controls the heating plate 17 to close and instructs the partition system 6 to open, connecting the front compartment and the rear compartment, thereby realizing the automated control of the temperature replenishment process.

[0075] In some alternative implementations, such as Figure 1 and Figure 3 As shown, several temperature sensors 9 are spaced apart along the axial direction of the autoclave 1. With this structure, since the fan 12 is located at one end of the autoclave 1 along its axial direction, the airflow inside the autoclave 1 blows from one end to the other. Through the several temperature sensors 9 spaced apart along the axial direction of the autoclave 1, the temperature gradient of the airflow inside the autoclave 1 can be collected in real time and fed back to the control system 4. The control system 4 dynamically adjusts the speed of the fan 12 and the power of the heating plate 17 according to the temperature gradient deviation, thereby realizing the coordinated closed-loop control of the temperature field and the flow field inside the autoclave 1.

[0076] In some optional embodiments, the autoclave 1 is connected to a safety valve, which is connected to the air circuit of the front compartment. When the pressure in the front compartment exceeds a preset safety limit, the safety valve automatically opens to release pressure, preventing the autoclave 1 from being damaged by overpressure and ensuring the safety of personnel and equipment.

[0077] In some alternative implementations, such as Figure 6 As shown, the autoclave 1 includes an inner tank 14 and an outer tank 15, which are connected as one unit by a plurality of grating plates 16.

[0078] In some alternative embodiments, the deflector assembly 13 includes an inner housing 132 and an outer housing 133, the inner housing 132 and the deflector 131 are integrally formed, the inner housing 132 and the outer housing 133 are detachably connected, the inner housing 132 is sealed to the inner tank 14, and the outer housing 133 is sealed to the outer tank 15.

[0079] In some alternative embodiments, the sealing surfaces of the inner shell 132 and the inner tank 14 are sealed by a sealing ring, and the outer shell 133 and the outer tank 15 are sealed by a flange cover.

[0080] In some optional embodiments, a movable sealing surface may be provided on the inner tank 14, and a sealing ring is provided on the movable sealing surface. The movable sealing surface and the inner tank body are slidably connected, and the two are sealed and slidably connected by the sealing ring. An axial driving component is provided on the outer wall of the inner tank 14. The axial driving component can drive the movable sealing surface to move axially along the inner tank 14. When the inner shell 132 is aligned with the inner tank 14, the axial driving component drives the movable sealing surface, so that the sealing ring on the movable sealing surface is pressed against the sealing surface of the inner shell 132 to achieve a press-fit seal.

[0081] In some alternative implementations, such as Figure 4 and Figure 5 As shown, the inner shell 132 and the outer shell 133 are detachably connected by a limiting member 134.

[0082] In some alternative implementations, such as Figure 4 and Figure 5 As shown, the limiting member 134 includes at least three pins, all of which are connected between the inner housing 132 and the outer housing 133. The at least three pins are arranged in a non-parallel configuration to ensure that the inner housing 132 does not shift relative to the outer housing 133. In this embodiment... Figure 5 As shown, four pins are used to position the inner housing 132, thereby fixing the position of the guide plate 131.

[0083] In this embodiment, an autoclave connects or disconnects the front and rear compartments via a partition system 6. When disconnected, the guide vane assembly 13 connected to the rear compartment can be replaced via a replacement system 2, allowing for the replacement of different guide vanes 131. During this process, the environment of the workpiece placed in the front compartment remains unchanged. After the guide vane 131 is replaced, the rear compartment is resealed, and the rear compartment is heated and pressurized to the conditions of the front compartment. The partition system 6 then connects the front and rear compartments, and the process continues using the replaced guide vane 131. The thermal history is uninterrupted, and the processing results of the same batch of workpieces under different conditions of the guide vanes 131 are compared under the same thermal history benchmark. The reliability and repeatability of the process data are excellent. At the same time, the automatic loading and unloading of the guide vane assembly 13 relative to the rear compartment is realized. Only the operators need to load and unload the guide vanes 131 on the guide vane assembly 13. No personnel need to enter the compartment to operate, which reduces safety and quality risks, improves assembly efficiency, and meets the requirements of high frequency and rapid switching of multiple working conditions. The autoclave has a simple structure, is easy to use, and has good effect.

[0084] Example 4 like Figures 1 to 8 As shown, the method of using an autoclave according to the present invention utilizes an autoclave as described in Example 3, and the method includes the following steps: R1. In the first stage, the workpiece is placed in the front chamber, the autoclave 1 is sealed, the control system 4 starts the air compressor 3 to pressurize the autoclave 1, starts the heating plate 17 to heat the autoclave 1, and starts the fan 12 to form a heat flow in the autoclave 1 through the guide plate 131.

[0085] R2. After the time required for the first stage is reached, the second stage begins. The control system 4 controls the fan 12 to stop running and starts the first motor 63 to rotate. The first motor 63 drives the partition plate 61 to rotate through the valve body 62, sealing and isolating the front chamber and the rear chamber. The pressures of the front chamber and the rear chamber are independent of each other. During the isolation period, the pressure and temperature conditions of the workpiece in the front chamber are maintained within the set allowable fluctuation range by means of the thermal inertia of the autoclave 1, the temperature adjustment of the heating plate 17, and the pressure adjustment of the pressure control component.

[0086] R3. The control system 4 controls the opening of the solenoid valve 8 connected to the rear compartment and controls the pressure relief valve to depressurize the rear compartment, reducing the pressure of the rear compartment to normal pressure. The pressure is monitored and fed back by the pressure sensor 7.

[0087] R4. The control system 4 controls the second motor 21 to start, and the second motor 21 drives the lead screw 22 to rotate, thereby driving the slide table 23 to slide along the slide rail 24, and the guide plate assembly 13 detaches from the rear compartment; one method is to replace the overall structure of the guide plate 131 and the inner shell 132 of the guide plate assembly 13 that has detached from the rear compartment, and another method is to move other guide plate assemblies 13 that already have different overall structures of the guide plate 131 and the inner shell 132 into the rear compartment. During the moving process, the sealing ring is squeezed and deformed to achieve the sealing of the autoclave 1.

[0088] R5. The control system 4 starts the air compressor 3 to pressurize the rear compartment. The control system 4 continuously monitors the rear compartment pressure data through the pressure sensor 7. When the absolute value of the difference between the rear compartment pressure and the front compartment pressure is lower than or equal to the set pressure threshold (generally not exceeding 0.02MPa), the control system 4 controls the solenoid valve 8 to close. The control system 4 starts the heating plate 17 to adjust the temperature of the rear compartment. The control system 4 continuously monitors the rear compartment temperature data through the temperature sensor 9. When the absolute value of the difference between the rear compartment pressure and the front compartment temperature is lower than or equal to the set temperature threshold, the control system 4 controls the heating plate 17 to be de-energized and shut down.

[0089] R6. The control system 4 starts the first motor 63 to rotate. The first motor 63 drives the partition plate 61 to rotate through the valve body 62, connecting the front chamber and the rear chamber. The control system 4 starts the fan 12 to form a hot flow in the autoclave 1 through the new guide plate 131, continuing the hot pressing process, and realizing the replacement of the guide plate 131 under the condition that the thermal history of the workpiece in the front chamber remains unchanged.
