Subsequently, these electrical signals are transmitted to the display device via the signal transmission line according to the established electrical connection mode. The display device is usually an electronic display screen with a certain protective shell, which can process the received electrical signals and display the pressure value directly for the operator to check on site. The entire detection process relies on the relatively fixed connection between the components and the conventional installation layout, aiming to realize the continuous monitoring function of the pressure in the autoclave.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0032] Referring to Figure 1 - Figure 3 An embodiment provided by the utility model: a kind of autoclave pressure detection mechanism for chemical processing, including autoclave 1 and detection rod 13, connecting plate 2 is fixedly connected to the outer wall of autoclave 1, pressure gauge 23 is fixedly connected to the top of connecting plate 2, pressure gauge 23 is used to monitor the pressure change inside autoclave 1 in real time, ensure safety and stable operation, detection assembly 3 is fixedly connected to the top of connecting plate 2, responsible for providing high-precision pressure detection signal, detection assembly 3 side is provided with disassembly component, disassembly component is used to facilitate operator to carry out equipment maintenance;

[0033] Disassembly component includes connecting block one 5, connecting block one 5 is fixedly connected to the side wall of detection assembly 3, limiting groove 4 is formed in the inside of connecting plate 2, for cooperating with other components to realize quick fixing and unlocking, limiting column 6 is fixedly connected in the inside of connecting block one 5, the role of limiting column 6 is to provide the guide of disassembly component, and ensure accurate positioning in sliding process, lever 7 is slidably connected in the inside of limiting column 6, limiting ring 8 is fixedly connected to the outer wall of lever 7, for limiting the movement of elastic gasket 9, limiting ring 8 outer wall and limiting column 6 inner wall are slidably connected, limiting column 6 is provided with elastic gasket 9, the role of elastic gasket 9 is to provide certain resilience, one end of elastic gasket 9 is fixedly connected to the inner wall of limiting column 6, and the other end is fixedly connected to the upper surface of limiting ring 8, one end of lever 7 is fixedly connected with tapered block 10, for driving the movement of limiting ball 11, tapered block 10 outer wall is slidably connected with limiting ball 11, limiting ball 11 is matched with limiting groove 4, limiting assembly is arranged on the outer wall of detection rod 13, and limiting assembly is used to limit detection rod 13.

[0034] Specifically, when the high-pressure kettle pressure detection assembly for chemical processing needs to be quickly disassembled due to failure, regular calibration and verification, and replacement of the detection assembly according to different chemical processes, the operator can conveniently observe the pressure condition of the equipment through the pressure gauge 23, thereby realizing real-time understanding of the working state of the component. When the operator presses the lever 7, the lever 7 will slide along the inside of the limiting column 6 under the guidance of the limiting column 6. The sliding action of the lever 7 drives the limiting ring 8 to move synchronously. The movement of the limiting ring 8 further causes the elastic gasket 9 to elastically deform. The elastic deformation process causes the conical block 10 to be compressed and displaced. The movement of the conical block 10 causes the limiting ball 11 to slide along the outer wall of the conical block 10 under pressure. In the process of continuous movement of the conical block 10, the limiting ball 11 is pushed out of the limiting groove 4, thereby realizing unlocking. At this time, the limiting ball 11 slides out of the limiting groove 4, so that the locking mechanism is released, and the disassembly and installation operations are completed. When the conical block 10 generates sufficient pressure, the limiting ball 11 is forced to be clamped into the inside of the limiting groove 4, thereby fixing the entire detection assembly 3, ensuring that the equipment is in a safe and stable working state. The operator can quickly and safely disassemble and install the equipment, while ensuring the stability and reliability during the operation process.

[0035] Referring to Figure 4 and Figure 5 , the limiting assembly includes a connecting seat 12 and a fixed plate 14. The connecting seat 12 is fixedly connected to the outer wall of the high-pressure kettle 1 and serves as a basic support structure of the limiting assembly, ensuring that it can withstand internal pressure changes and vibrations during the operation of the high-pressure kettle 1. The fixed plate 14 is fixedly connected to the inner wall of the connecting seat 12. The main function of the fixed plate 14 is to provide a solid platform for installing other components. The side wall of the fixed plate 14 is fixedly connected with a connecting block 15, and the side wall of the fixed plate 14 is fixedly connected with a connecting shaft 16. The connecting shaft 16 is slidably connected with a sliding shaft 17 inside, ensuring that there is no excessive deviation or shaking during sliding, avoiding affecting the accuracy of the limiting assembly. The sliding shaft 17 is fixedly connected with a fixed plate 18 on one side.

[0036] Specifically, when the detection rod needs to be limited due to factors such as vibration and internal pressure fluctuation during equipment operation, which easily leads to displacement, shaking or loosening of the detection rod, the detection rod 13 is placed inside the connecting seat 12. At this time, the extrusion force on the outer wall of the detection rod 13 starts to act on the U-shaped plate 22. The U-shaped plate 22 is made of rubber or other materials and deforms under the influence of the extrusion force. The deforming force is transmitted to the fixed plate 18 along the structure of the U-shaped plate 22. The fixed plate 18, as the main support part of the structure, bears the pressure from the U-shaped plate 22 and further transmits this force to the sliding block 19 through the connection with the U-shaped plate 22.

[0037] Referring to Figure 4And Figure 5 The fixed plate two 18 is fixedly connected with a sliding block 19 on one side, and the outer wall of the sliding block 19 is fixedly connected with an air chamber 20 for ensuring smooth movement of the assembly. The air chamber 20 slides on the outer wall of the connecting block two 15 to ensure smooth sliding of the air chamber 20 during operation. The side wall of the fixed plate two 18 is fixedly connected with a fixed disc 21 which plays a reinforcing and connecting role on the side wall. The fixed disc 21 is fixedly connected with a U-shaped plate 22 on one side. The U-shaped plate 22 is made of rubber material and is used for limiting the detection rod 13.

[0038] Specifically, the sliding block 19 will slide in the air chamber 20 under the push of the fixed plate two 18. The air chamber 20 is designed with a sliding track and a guide device to ensure smooth movement of the sliding block 19 without error. The movement of the sliding block 19 drives the two sliding shafts 17 to synchronously slide in the connecting shaft 16. The cooperation of the sliding shafts 17 and the connecting shaft 16 ensures that the two can stably move and bear load. The sliding of the sliding shafts 17 not only pushes the fixed plate two 18 in the axial direction, but also makes the fixed plate two 18 elastically deform under external force. With the elastic deformation of the fixed plate two 18, an opposite force is generated in the assembly to the applied pressure. This counterforce makes the U-shaped plate 22 more closely fit the outer wall of the detection rod 13. The fitting effect ensures the stability and accuracy of the detection rod 13 and prevents it from deviating during operation, thereby ensuring the realization of the limiting function and ensuring the safety and stability of the equipment.

[0039] Working principle: When using the device, the pressure condition can be conveniently observed through the pressure gauge 23. The operating personnel press the lever 7 to make it slide in the limiting column 6. The sliding of the lever 7 will further drive the limiting ring 8 to move synchronously. The movement of the limiting ring 8 drives the elastic gasket 9 to elastically deform, thereby making the conical block 10 move. When the conical block 10 moves, the limiting ball 11 will slide along the outer wall thereof. Under the pressure of the conical block 10, the limiting ball 11 will be clamped into the limiting groove 4 to be fixed. When the conical block 10 moves, the limiting ball 11 will slide out of the limiting groove 4 along the outer wall of the conical block 10 to be unlocked, thereby achieving the effect of conveniently allowing the operating personnel to quickly disassemble and install the detection assembly 3, greatly improving the maintenance convenience. During detection, the detection rod 13 is arranged in the connecting seat 12. Under the extrusion force of the outer wall of the detection rod 13, the U-shaped plate 22 is deformed to further transmit the force to the fixed plate two 18. Under the driving of the fixed plate two 18, the sliding block 19 will slide in the air chamber 20, thereby making the two sliding shafts 17 synchronously slide in the connecting shaft 16. The sliding of the sliding shafts 17 will force the fixed plate two 18 to elastically deform, thereby generating an opposite force to support the fitting of the U-shaped plate 22 and the outer wall of the detection rod 13, thereby achieving the limiting effect.
