[0017] This utility model provides a quick-release anti-corrosion liner structure for a reaction vessel, as detailed below. Figure 1 To be continued Figure 3 The specific embodiments of this utility model will be described in detail below. For example... Figure 1As shown, the structure mainly includes the reactor body 1, annular support frame 2, arc-shaped liner unit 3, slot 4, locking block 5, elastic clamping component 6, locking assembly 7, guide assembly 11, and sealing strip 15. These components, through reasonable connection and cooperation, enable the rapid installation and removal of the anti-corrosion liner.

[0018] First, the annular support frame 2 is fixedly installed on the inner wall of the reactor body 1, located near the top area of ​​the reactor body 1, and evenly distributed along the circumference of the reactor body 1. Multiple slots 4 are provided on the inner side of the annular support frame 2, and these slots 4 are evenly spaced along the circumference of the annular support frame 2 to engage with the locking blocks 5 on the arc-shaped liner unit 3. For example... Figure 2 As shown, each arc-shaped liner unit 3 has a locking block 5 on its outer side. The number and position of the locking blocks 5 correspond one-to-one with the locking slots 4 on the annular support frame 2. After the locking block 5 is inserted into the locking slot 4, it is initially fixed by the elastic clamping member 6. The elastic clamping member 6 is a spring sheet embedded in the locking slot 4. One end of the spring sheet is fixedly connected to the bottom of the locking slot 4, and the other end is tightly fitted to the side of the locking block 5. This design allows the locking block 5 to be subjected to the elastic force of the spring sheet when inserted into the locking slot 4, thereby maintaining a stable connection.

[0019] Furthermore, the locking assembly 7 is located in the top area of ​​the annular support frame 2, used to further secure the arc-shaped liner unit 3. The locking assembly 7 includes multiple locking units, each consisting of a hinge seat 8, a locking rod 9, and a locking head 10. The hinge seat 8 is fixedly mounted on the top of the annular support frame 2, and the locking rod 9 is rotatably connected to the hinge seat 8 via a hinge shaft. The free end of the locking rod 9 is provided with a locking head 10, and the bottom of the locking head 10 is provided with a rubber pad with a thickness of 1mm-2mm and a material hardness of Shore A 60A-80A. The locking head 10 cooperates with the top edge of the arc-shaped liner unit 3. When the locking rod 9 is rotated to the locked state, the locking head 10 presses against the top edge of the arc-shaped liner unit 3, thereby ensuring the secure fixation of the arc-shaped liner unit 3. The middle part of the locking rod 9 is connected to the hinge seat 8 through a torsion spring. The function of the torsion spring is to keep the locking rod 9 in a locked state at all times, so as to prevent the locking rod 9 from loosening due to external vibration or impact.

[0020] In addition, a guide assembly 11 is disposed at the bottom area of ​​the annular support frame 2 to assist in the installation and positioning of the arc-shaped liner unit 3. The guide assembly 11 includes multiple guide units, each consisting of a guide seat 12, a guide rod 13, and a return spring 14. The guide seat 12 is fixedly disposed at the bottom of the annular support frame 2, and the guide rod 13 is slidably connected to the guide seat 12. One end of the guide rod 13 contacts the bottom edge of the arc-shaped liner unit 3, and the other end is provided with the return spring 14. The function of the return spring 14 is to push the guide rod 13 towards the arc-shaped liner unit 3, thereby ensuring that the arc-shaped liner unit 3 can be accurately aligned during installation. A ball bearing is provided at the end of the guide rod 13, embedded in the end of the guide rod 13 and fixed with screws. The diameter of the ball bearing is 5mm-8mm, and the material is stainless steel. The ball bearing design reduces the friction between the guide rod 13 and the arc-shaped liner unit 3, improving the smoothness of installation. Meanwhile, the guide seat 12 is provided with a lubrication channel inside. One end of the lubrication channel is connected to the sliding area of ​​the guide rod 13, and the other end is provided with an oil injection nozzle. The top of the oil injection nozzle is provided with a dust cover to facilitate the periodic injection of lubricating oil to reduce the wear of the guide rod 13.

[0021] To further enhance the sealing performance between the anti-corrosion liner and the reactor body 1, a sealing strip 15 is provided on the inner side of the annular support frame 2. The sealing strip 15 is continuously arranged circumferentially along the annular support frame 2, with a U-shaped cross-section and the U-shaped opening facing the outer side of the arc-shaped liner unit 3. The inner side of the sealing strip 15 is tightly fitted to the outer surface of the arc-shaped liner unit 3, effectively preventing media leakage. Furthermore, the inner surface of the arc-shaped liner unit 3 is coated with an anti-corrosion coating, with a thickness of 0.5mm-1mm, made of polytetrafluoroethylene (PTFE). The anti-corrosion coating significantly improves the corrosion resistance of the arc-shaped liner unit 3. Reinforcing ribs are provided on the outer surface of the arc-shaped liner unit 3, arranged radially along the arc-shaped liner unit 3, numbering 3-5, with a height of 2mm-4mm. The design of the reinforcing ribs enhances the structural strength of the arc-shaped liner unit 3, making it less prone to deformation under pressure.

[0022] A protective cover is also provided on the outside of the annular support frame 2, and the protective cover is fixedly connected to the annular support frame 2 by bolts. The protective cover is made of aluminum alloy, and its inner side is provided with a heat insulation layer with a thickness of 3mm-5mm and made of fiberglass. The design of the heat insulation layer effectively reduces the impact of high-temperature environment on the annular support frame 2 and extends its service life.

[0023] In practical applications, the installation process of this quick-release anti-corrosion liner structure for the reactor is as follows: First, multiple arc-shaped liner units 3 are sequentially installed onto the annular support frame 2. The locking block 5 of each arc-shaped liner unit 3 is inserted into the corresponding slot 4, and initial fixation is achieved through the elastic clamping component 6. Subsequently, the operator manually rotates the locking rod 9 to press the locking head 10 against the top edge of the arc-shaped liner unit 3, completing further fixation. During this process, the guide rod 13 in the guide assembly 11 pushes the arc-shaped liner unit 3 towards the center of the annular support frame 2 through the action of the return spring 14, ensuring the accurate installation position of the arc-shaped liner unit 3. Finally, it is checked whether the sealing strip 15 is tightly fitted with the arc-shaped liner unit 3 to ensure that the sealing performance of the overall structure meets the requirements.

[0024] When it is necessary to disassemble the arc-shaped liner unit 3, the operator only needs to manually rotate the locking rod 9 to disengage the locking head 10 from the top edge of the arc-shaped liner unit 3, and then remove the arc-shaped liner unit 3 from the annular support frame 2. Due to the presence of the elastic clamping element 6, the arc-shaped liner unit 3 will not suddenly fall off during disassembly, thus ensuring the safety of the operation.

[0025] The above embodiments describe in detail the structural composition and operating principle of this utility model. Through the coordinated cooperation of the annular support frame 2, the arc-shaped liner unit 3, the elastic clamping component 6, the locking component 7, and the guide component 11, the anti-corrosion liner can be quickly disassembled and assembled, while ensuring the stability and sealing of the installation.

[0026] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.

[0027] In the daily maintenance of the reactor, the anti-corrosion liner plates need to be disassembled periodically for cleaning and inspection. First, the operator installs multiple arc-shaped liner plate units 3 sequentially onto the annular support frame 2. The locking block 5 of each arc-shaped liner plate unit 3 is inserted into the corresponding slot 4. At this time, the spring sheet of the elastic clamping element 6 is tightly fitted with the side of the locking block 5, forming a preliminary fixation. Because the spring sheet has a certain elastic deformation capacity, it can provide a continuous force, allowing the locking block 5 to maintain a stable connection within the slot 4, preventing loosening due to vibration or impact.

[0028] Subsequently, the operator manually rotates the locking rod 9. Through the action of the torsion spring on the hinge seat 8, the locking rod 9 drives the locking head 10 to press against the top edge of the arc-shaped liner unit 3. The rubber pad design not only increases the friction between the locking head 10 and the arc-shaped liner unit 3, but also avoids surface damage caused by direct contact. The locking assembly 7 ensures that the arc-shaped liner unit 3 will not shift during the operation of the reactor, thereby improving the stability of the overall structure.

[0029] During this process, the guide rod 13 in the guide assembly 11 moves towards the arc-shaped liner unit 3 under the action of the return spring 14, pushing it closer to the center of the annular support frame 2. The ball bearing design at the end of the guide rod 13 reduces frictional resistance, making the installation of the arc-shaped liner unit 3 smoother. At the same time, lubricating oil can be injected into the lubrication channel inside the guide seat 12 through the grease nipple, further reducing the wear of the guide rod 13 and extending its service life. With the assistance of the guide assembly 11, the arc-shaped liner unit 3 can be precisely aligned, ensuring the accuracy of the installation position.

[0030] The sealing strip 15 is arranged circumferentially along the annular support frame 2. Its U-shaped cross-section design allows the sealing strip 15 to fit tightly against the outer surface of the arc-shaped liner unit 3, effectively preventing media leakage. Furthermore, the polytetrafluoroethylene (PTFE) anti-corrosion coating on the inner side of the arc-shaped liner unit 3 significantly improves its corrosion resistance, while the reinforcing ribs on the outer side enhance structural strength, making it less prone to deformation under pressure. These designs work together to ensure the reliability and durability of the anti-corrosion liner in practical use.

[0031] When the arc-shaped liner unit 3 needs to be disassembled, the operator only needs to manually rotate the locking rod 9 to disengage the locking head 10 from the top edge of the arc-shaped liner unit 3. The arc-shaped liner unit 3 can then be removed from the annular support frame 2. Due to the presence of the elastic clamping element 6, the locking block 5 is controlled by the spring plate during its disengagement from the locking groove 4, preventing sudden detachment and ensuring operational safety.

[0032] The protective cover further protects the annular support frame 2, and its inner fiberglass insulation layer effectively reduces the impact of high-temperature environments on the annular support frame 2, extending the service life of the equipment. The entire disassembly and assembly process is simple and efficient, significantly improving the maintenance efficiency of the reactor.

[0033] The above content describes in detail the specific operating steps and implementation principles of this utility model in practical applications. Through reasonable structural design and component matching, this utility model achieves rapid assembly and disassembly of the anti-corrosion lining plate, while ensuring the stability and sealing of the installation, thus meeting the needs of efficient equipment maintenance in chemical production.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
