[0021] In hot isostatic pressing equipment, the heat shield device achieves effective heat insulation in high-temperature areas through the coordinated work of key components such as the heat shield body, reflective layer, insulation material layer, support structure, and sealing structure, reducing heat loss and thermal impact on the surrounding environment, and improving the energy efficiency and working stability of hot isostatic pressing equipment. Hot isostatic pressing equipment will produce a high temperature and high pressure environment during operation. The heat shield device needs to be able to maintain stability and integrity under such extreme conditions. It should be able to withstand the thermal stress, mechanical stress, and chemical corrosion caused by high temperature and high pressure to avoid deformation, damage, or failure.

[0022] The heat shield device needs to significantly improve its thermal insulation performance to ensure that it can effectively reduce the conduction of heat to other parts of the hot isostatic pressing equipment under high temperature conditions, thereby maintaining a stable and uniform temperature inside the hot isostatic pressing equipment. This requires the heat shield material to have extremely low thermal conductivity and good thermal stability, and to be able to maintain efficient thermal insulation under long-term high temperature conditions.

[0023] With the continuous progress of material science and manufacturing technology, the heat shield device of hot isostatic pressing equipment is also constantly developing and improving. The application of new insulation materials and advanced manufacturing processes has significantly improved the performance of the heat shield device.

[0024] Although sealing technology is used in existing technical solutions, the sealing performance of the heat shield device may be challenged under extreme working conditions. Long-term high temperature and high pressure environment may cause material aging, deformation or damage, thereby affecting the sealing effect of the heat shield and causing heat leakage.

[0025] In order to maintain the stability and position accuracy of the heat shield, special support and fixing structures are usually designed. These structures not only need to bear the weight of the heat shield itself, but also need to withstand the vibration and impact generated during the working process. The support and fixing structure of the heat shield device may have certain limitations in design and manufacturing. Under high temperature and high pressure environment, the support structure may be affected by thermal stress and deform or loosen, resulting in the verticality of the heat shield's vertical tube being affected, which in turn affects the stability and positioning accuracy of the heat shield.

[0026] In order to overcome the above problems, the embodiments of the present application provide a method and device for controlling the verticality of a multi-layer vertical cylinder of a hot isostatic pressing equipment.

[0027] A method and device for controlling the verticality of a multi-layer vertical cylinder of hot isostatic pressing equipment according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0028] Figure 1 It is a structural schematic diagram of a hot isostatic pressing equipment provided in an embodiment of the present application; Figure 2 It is a flow chart of a method for controlling the verticality of a multi-layer vertical cylinder of hot isostatic pressing equipment provided in an embodiment of the present application; Figure 3 This is a schematic diagram of a verticality control device for a multi-layer vertical tube of hot isostatic pressing equipment provided in an embodiment of the present application. Figures 1 to 3 The method and device for controlling the verticality of a multi-layer vertical tube of a hot isostatic pressing equipment in an embodiment of the present application are described in detail.

[0029] In the method for controlling the verticality of a multi-layer vertical cylinder of a hot isostatic pressing equipment in an embodiment of the present application, Figure 1 As shown, the hot isostatic pressing equipment includes an ultra-high pressure container 100 and an inverted cup-shaped heat shield 200 arranged in the ultra-high pressure container, a heating body (not shown in the figure) is arranged inside the heat shield, and the heat shield includes a multi-layer vertical cylinder. A non-contact distance measurement sensor 500 is arranged on the inner wall of the ultra-high pressure container, and a support structure 300 with adjustable inclination is arranged below the multi-layer vertical cylinder.

[0030] like Figure 2 As shown in the figure, the method for controlling the verticality of the multi-layer vertical tube of hot isostatic pressing equipment includes: Step S201, obtaining distance measurement data obtained by measuring the distance of the outer wall of the multi-layer vertical tube using a non-contact distance sensor.

[0031] Step S202, obtaining verticality data of multi-layer vertical tubes according to distance measurement data.

[0032] Step S203: When the verticality data exceeds a set first threshold, adjust the inclination of the support structure according to the verticality data.

[0033] The embodiment of the present application discloses a high-precision verticality control scheme for a high-sealing multi-layer vertical tube of a heat shield in a hot isostatic pressing equipment. The scheme adopts a high-precision verticality control system to ensure that the multi-layer vertical tube structure can maintain high-precision verticality under ultra-high temperature and ultra-high pressure conditions, thereby improving the overall performance and operating stability of the hot isostatic pressing equipment.

[0034] Ultra-high temperature and ultra-high pressure conditions will cause great thermal and mechanical stress to the heat shield material, resulting in reduced sealing performance or even failure. High temperature environment may cause the material to expand or soften, affecting the sealing effect; while high pressure environment may cause the sealing structure to deform or damage. The technical solution of the embodiment of the present application optimizes the heat shield structure design and material selection, so that the heat shield can maintain good sealing performance.

[0035] Specifically, the column can use high temperature and high pressure resistant materials to have higher thermal stability and mechanical strength, and be able to maintain stable performance under extreme working conditions. In addition, the surface of the heat shield and the multi-layer column can be specially treated, such as spray coating or nano material treatment, to improve its high temperature and high pressure resistance and corrosion resistance, thereby improving its performance without changing the equipment structure. In addition, the column can be made of high-strength, deformation-resistant materials to obtain a multi-layer column structure with sufficient rigidity and stability. In order to cope with the deformation and stress problems under ultra-high temperature and ultra-high pressure environments, it is necessary to consider the thermal expansion coefficient and mechanical properties of the material when selecting the column material, and design a reasonable support structure for the column.

[0036] Specifically, the vertical tube can be made of composite materials or alloy materials, so that it can have high rigidity and deformation resistance. In the process of manufacturing the vertical tube, precision processing technology can be used to ensure that the dimensional accuracy and surface quality of each component meet the requirements. During the installation of the vertical tube, high-precision measuring instruments can be used to monitor and adjust the verticality of the vertical tube in real time to ensure that the verticality error of the vertical tube is within the allowable range.

[0037] The technical solution of the embodiment of the present application optimizes the sealing design in the prior art. Specifically, the sealing material adopts a material that is resistant to high temperature, high pressure and corrosion, such as a composite material or an alloy material, which can still maintain stable physical and chemical properties under ultra-high temperature and ultra-high pressure environment. Composite materials or alloy materials are selected as the main sealing materials, which can withstand ultra-high temperature and ultra-high pressure environments and have good corrosion resistance and anti-aging properties. Through a special molding process, the sealing material is made into a sealing structure with excellent performance, which can ensure that the vertical cylinder can still maintain a tight fit and sealing effect under high temperature and high pressure. In addition, multiple sealing structures can be designed, including static seals and dynamic seals, to ensure a tight fit between the top of the heat insulation screen and the hot isostatic pressing equipment, and improve the reliability and durability of the seal. In addition, a flexible seal and a pre-tightening force automatic adjustment mechanism can be used between the vertical cylinders of the heat insulation screen, and the size of the pre-tightening force can be automatically adjusted to adapt to the sealing requirements under different temperatures and pressures, ensuring that the sealing effect is stable and reliable. During the installation process, special tools can be used to accurately position and press the vertical cylinders to ensure that the gaps between the vertical cylinders are uniform and consistent, thereby improving the sealing performance.

[0038] Before the hot isostatic pressing equipment is put into operation, the sealing performance of the heat shield can be fully tested through air pressure testing to ensure that there is no leakage. During the operation of the hot isostatic pressing equipment, the sealing performance can be kept stable through regular inspections. For example, the sealing performance of the heat shield can be monitored in real time, and leakage can be detected in time through pressure sensors or leak detection devices. Adding a leak detection device can monitor the sealing effect in real time to ensure that leakage can be detected and handled in time when it occurs.

[0039] The technical solution of the embodiment of the present application significantly improves the sealing performance of the heat insulation shield by adopting high temperature and high pressure resistant materials and optimizing the sealing structure design, effectively preventing leakage problems under ultra-high temperature and ultra-high pressure conditions, thereby ensuring the stable operation of the hot isostatic pressing equipment.

[0040] In an embodiment of the present application, a temperature sensor and a pressure sensor are provided in the heat insulation screen. Before adjusting the inclination of the supporting structure according to the verticality data, the temperature sensor data and the pressure sensor data collected by the temperature sensor and the pressure sensor can be obtained, and the first threshold can be corrected according to the temperature sensor data and the pressure sensor data.

[0041] Temperature sensors and pressure sensors are provided to monitor the temperature and pressure changes in the working environment in real time, and the temperature and pressure changes may cause the verticality of the multi-layer vertical tube to change. Among them, the correspondence between temperature, pressure and the first threshold value can be preset, and the first threshold value can be corrected based on the correspondence and the temperature sensor data and pressure sensor data monitored in real time. By correcting the first threshold value, effective temperature and pressure compensation can be performed, thereby reducing the influence of the working environment on the verticality of the vertical tube and the sealing performance of the heat insulation screen, and further improving the reliability and durability of the hot isostatic pressing equipment. Specifically, considering the influence of temperature and pressure on the verticality of the vertical tube, the verticality control parameters are adjusted in real time according to the temperature and pressure changes in the working environment, and the deformation of the vertical tube caused by thermal expansion and mechanical stress is predicted and corrected by the algorithm, so as to compensate for the influence of temperature and pressure on the verticality of the vertical tube, maintain the high-precision verticality of the vertical tube, and maintain the stability and consistency of the working environment.

[0042] By adopting the technical solution of the embodiment of the present application, the verticality of the vertical barrel of the heat shield of the hot isostatic pressing equipment can be accurately controlled, which can reduce production delays caused by downtime and improve production efficiency. In addition, high sealing and high-precision verticality control reduce energy consumption and material loss, reduce additional costs caused by leakage and maintenance, and help reduce the operating costs of enterprises.

[0043] In the embodiment of the present application, after adjusting the inclination of the support structure according to the verticality data, the heating temperature of the heating element and the pressure distribution data of the heat insulation screen can be adjusted according to the temperature sensor data and the pressure sensor data.

[0044] Specifically, by optimizing the temperature and pressure distribution of the hot isostatic pressing equipment, the interference of the working environment on the verticality of the cylinder can be reduced.

[0045] In the embodiment of the present application, when obtaining the verticality data of the multi-layer vertical tube according to the distance measurement data, the angle between the length direction and the vertical direction of the multi-layer vertical tube can be obtained according to the distance measurement data and the standard distance data, and then the verticality data can be obtained according to the angle.

[0046] Specifically, the distance measurement data is the measured distance data. The measured distance data can be obtained by a non-contact distance sensor according to the following Figure 1The dotted line direction shown is the measurement data obtained by horizontally measuring the outer vertical tube. Horizontal distance measurement is to measure the distance between two objects in the horizontal direction. When the vertical tube is set vertically, the horizontal distance between the non-contact distance sensor and the outer vertical tube is the standard distance data. It can be seen that if the measured distance data is equal to the standard distance data, it proves that the vertical tube is perpendicular to the horizontal plane. If the measured distance data is not equal to the standard distance data, it proves that the vertical tube is not perpendicular to the horizontal plane, and the inclination of the supporting structure needs to be adjusted. Using geometric knowledge, the angle between the length direction and the vertical direction of the multi-layer vertical tube can be obtained based on the measured distance data and the standard distance data.

[0047] In the embodiment of the present application, a cushion block 400 with a variable height is provided under the support structure. When the inclination of the support structure is adjusted according to the verticality data, an adjustment signal can be generated according to the verticality data to drive the lifting motor to rotate so as to raise or lower the height of the cushion block. The height of the cushion block can be adjusted under the traction of the lifting motor, thereby raising or lowering the height of the cushion block, and then adjusting the inclination of the support structure to maintain the verticality of the multi-layer vertical tube of the heat insulation screen.

[0048] In the monitoring and protection scheme of the heat insulation screen in the embodiment of the present application, an alarm signal can be generated when the temperature sensor data exceeds a preset second threshold and / or the pressure sensor data exceeds a preset third threshold to alarm the abnormal working state of the heat insulation screen.

[0049] Specifically, the hot isostatic pressing equipment can be monitored through multiple safety means such as temperature sensors and pressure sensors, and the environmental parameters inside and outside the heat insulation screen, such as temperature and pressure changes, can be monitored in real time. Once an abnormality is found, an alarm will be immediately triggered and protective measures will be initiated, such as reducing the heating power or stopping heating, to ensure the safe operation of the hot isostatic pressing equipment.

[0050] The technical solution of the embodiment of the present application discloses a verticality control system based on high-precision distance measurement technology, which calculates the verticality deviation of the vertical tube by measuring the deflection angle. After the measured data is calculated and analyzed in real time, the vertical tube is fine-tuned by the control mechanism to maintain high-precision verticality. Specifically, the verticality of the multi-layer vertical tube can be monitored in real time, the measurement results can be compared with the preset values, and the support structure and position of the vertical tube can be adjusted by the feedback control system to achieve high-precision verticality control. In addition, the technical solution of the embodiment of the present application can automatically adjust the verticality of the vertical tube according to the measurement results to keep it within the preset accuracy range by equipping it with an automatic adjustment mechanism. Real-time monitoring and adjustment of the verticality of the vertical tube by the high-precision verticality control system can effectively reduce the deformation of the vertical tube due to thermal expansion and mechanical stress, ensure the stability and accuracy of the multi-layer vertical tube structure, and thus improve the performance of the entire hot isostatic pressing equipment.

[0051] Furthermore, the technical solution of the embodiment of the present application can also provide an adaptive adjustment mechanism that can adaptively adjust the verticality according to changes in the working environment. The mechanism can automatically adjust the support structure and position of the vertical cylinder by sensing changes in temperature and pressure to maintain its high-precision verticality, thereby reducing manual intervention and improving the automation level of the hot isostatic pressing equipment.

[0052] In the embodiment of the present application, a sturdy and high-temperature resistant support structure can also be designed to ensure that the heat insulation shield maintains stability and positioning accuracy in a high temperature and high pressure environment, and a reliable fixing method can be used to ensure close fit and fixation between the heat insulation shield and the hot isostatic pressing equipment.

[0053] In the embodiment of the present application, a central control system based on PLC or industrial computer can be built to integrate functions such as thermal insulation shield sealing monitoring, multi-layer vertical tube verticality control, and temperature and pressure monitoring, and realize centralized monitoring and remote operation of the entire hot isostatic pressing equipment through the host computer software. Before operation, the central control system can be initialized and relevant parameters and thresholds can be input. After starting the hot isostatic pressing equipment, the sealing performance of the thermal insulation shield and the verticality of the multi-layer vertical tube can be monitored in real time. If abnormal conditions or alarm information are found, they can be processed and adjusted in time to ensure the stable operation of the hot isostatic pressing equipment.

[0054] In the disclosed embodiments, the high sealing design and high-precision verticality control reduce the failure rate of the heat shield and the multi-layer vertical tube during operation, reduce the frequency of maintenance and replacement of parts, and thus extend the service life of the hot isostatic pressing equipment.

[0055] In the verticality control device for a multi-layer vertical cylinder of hot isostatic pressing equipment in an embodiment of the present application, the hot isostatic pressing equipment includes an ultra-high pressure vessel and an inverted cup-shaped heat shield arranged in the ultra-high pressure vessel, a heating body is arranged inside the heat shield, the heat shield includes multi-layer vertical cylinders, a non-contact distance measurement sensor is arranged on the inner wall of the ultra-high pressure vessel, and a support structure with adjustable inclination is arranged below the multi-layer vertical cylinders.

[0056] like Figure 3 As shown, the hot isostatic pressing equipment multi-layer vertical tube control device includes: The measurement data acquisition module 301 is used to acquire distance measurement data obtained by measuring the distance of the outer wall of the multi-layer vertical tube using a non-contact distance sensor.

[0057] The verticality acquisition module 302 is used to acquire verticality data of multi-layer vertical tubes according to the distance measurement data.

[0058] The adjustment module 303 is used to adjust the inclination of the support structure according to the verticality data when the verticality data exceeds a set first threshold.

[0059] In an embodiment of the present application, a pad with variable height is arranged under the supporting structure. The height of the pad can be adjusted under the traction of the lifting motor. When the inclination of the supporting structure is adjusted according to the verticality data, an adjustment signal can be generated according to the verticality data to drive the lifting motor to rotate to raise or lower the height of the pad, thereby adjusting the inclination of the supporting structure and maintaining the verticality of the multi-layer vertical tubes of the heat insulation screen.

[0060] In an embodiment of the present application, a temperature sensor and a pressure sensor are provided in the heat insulation shield, and the device also includes: a correction module for obtaining temperature sensor data and pressure sensor data collected by the temperature sensor and the pressure sensor, and correcting the first threshold value according to the temperature sensor data and the pressure sensor data.

[0061] Setting temperature sensors and pressure sensors can monitor the temperature and pressure changes in the working environment in real time. By correcting the first threshold, effective temperature and pressure compensation can be performed, thereby reducing the impact of the working environment on the verticality of the cylinder and the sealing performance of the heat insulation screen, and further improving the reliability and durability of the hot isostatic pressing equipment.

[0062] In the embodiment of the present application, the hot isostatic pressing equipment multi-layer vertical cylinder control device also includes an alarm, which is used to generate an alarm signal when the temperature sensor data exceeds the preset second threshold value and / or the pressure sensor data exceeds the preset third threshold value, so as to alarm the abnormal working state of the heat insulation screen. The configuration of the alarm can immediately trigger an alarm and take corresponding emergency measures when an abnormal situation is detected.

[0063] In the embodiment of the present application, at least two sealing structures are provided between the ultra-high pressure container and the heat shield. The at least two sealing structures may include a static seal and a dynamic seal. For example, a sealing structure may include a lip seal ring, a graphite packing group and an O-ring.

[0064] In an embodiment of the present application, a reflective layer is provided on the inner wall of the heat insulation screen, and the reflectivity of the reflective layer is higher than a preset reflectivity threshold value, so as to reflect thermal radiation back to the heating area, thereby improving the thermal insulation performance of the heat insulation screen.

[0065] In the embodiment of the present application, each layer of the multi-layer vertical tube structure of the heat insulation shield device plays a specific insulation and protection role. For example, the external structure may use strong and high temperature resistant materials to withstand the pressure and temperature changes of the external environment; the interior uses efficient insulation materials to reduce the conduction of heat to other parts of the hot isostatic pressing equipment. The main material of the heat insulation shield can generally be a material with stable high temperature performance and low thermal conductivity. These materials have good thermal insulation properties and mechanical strength, and can operate stably for a long time under high temperature and high pressure environments. Under long-term high temperature and high pressure environments, the sealing performance of the heat insulation shield device should remain long-lasting and stable, and not easily affected by environmental factors. The high airtightness design can reduce the possibility of heat leakage and the entry of external impurities, further enhancing the operating stability and product quality of the hot isostatic pressing equipment.
