[0002] In the field of chemical production, catalytic cyclization reactions are a key type of chemical reaction, often used to synthesize various cyclic compounds, and are widely used in the production processes of pharmaceutical intermediates, fine chemicals, etc.

[0003] Traditional reaction vessel sealing methods often employ a combination of gaskets and numerous bolts. Tightening the bolts deforms the gasket, achieving a seal between the vessel lid and body. However, this method is susceptible to the influence of assembly precision, making it difficult to form a uniform and reliable sealing surface. Furthermore, over long-term use, the sealing performance of the sealing parts is prone to degradation, failing to effectively address potential changes in sealing requirements during the reaction process. This, in turn, negatively impacts the safety and stability of production. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a safe sealing structure for a catalytic cyclization reaction vessel, which has the advantages of uniform and reliable sealing and resistance to attenuation of sealing performance. This solves the problems of traditional sealing methods where the sealing effect is greatly affected by assembly precision and the sealing performance is easily attenuated.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a safe sealing structure for a catalytic cyclization reaction vessel, comprising a vessel body, a vessel cover at the top of the vessel body, three fixing rods fixedly installed at equal intervals around the outer side of the vessel cover, a sealing groove at the bottom of the vessel cover, an annular plate fixedly installed at the bottom of the vessel cover, an annular mounting groove at the top of the vessel body near the vessel opening, a plurality of adjusting components arranged at equal intervals around the inner side of the annular mounting groove, the adjusting components inside the annular mounting groove penetrating the inner surface of the vessel body, a sealing part at the top of the adjusting components, and three locking components arranged at equal intervals around the outer side of the vessel body near the vessel opening, the fixing rods cooperating with the locking components.

[0006] As a preferred embodiment of the present invention, the adjustment assembly includes two fixing plates, which are symmetrically fixedly installed inside the annular mounting groove. An arc-shaped guide groove is provided on one side of each fixing plate, and a rectangular guide groove is provided on the other side of each fixing plate.

[0007] As a preferred embodiment of this utility model, the adjusting component further includes a movable hole, which is located on the inner side of the tank body near the tank opening. The movable hole is connected to an annular mounting groove. A push block is movably installed inside the movable hole, and a sealing gasket is fixedly installed on the outer side of the push block. The push block is used in conjunction with an annular plate.

[0008] As a preferred technical solution of this utility model, the adjustment component further includes a push rod, one end of which is rotatably mounted on the side of the push block near the fixed plate, and first round rods are symmetrically fixedly mounted on both sides of the push rod, the first round rods being movably sleeved inside the arc-shaped guide groove.

[0009] As a preferred embodiment of the present invention, the sealing part includes a top rod, which is disposed between two fixed plates. A second round rod is symmetrically fixedly installed on both sides of the top rod, and the second round rod is movably sleeved inside the rectangular guide groove.

[0010] As a preferred embodiment of this utility model, the sealing part further includes an annular mounting plate, which is movably fitted inside the annular mounting groove. The bottom of the annular mounting plate is fixedly installed with the top of the top rod. Several springs are fixedly installed at the bottom of the annular mounting plate, and the other end of the springs is fixedly installed with the inner bottom surface of the annular mounting groove. An annular sealing ring is fixedly installed at the top of the annular mounting plate, and the annular sealing ring is movably fitted inside the sealing groove.

[0011] As a preferred embodiment of the present invention, the locking assembly includes a mounting block, which is fixedly installed on the outer side of the tank body near the tank opening. A slot is provided on the top of the mounting block, and the fixing rod is movably sleeved inside the slot. A locking block is rotatably installed on one side of the mounting block, and a mounting hole is provided on the top of the locking block.

[0012] As a preferred embodiment of this utility model, the locking assembly further includes a J-shaped locking rod, which is movably installed inside the mounting hole. The J-shaped locking rod is inverted, and a bolt is rotatably installed at the bottom of the locking block. A threaded hole is provided at one end of the J-shaped locking rod near the bolt, and the bolt is threadedly connected inside the threaded hole.

[0013] The beneficial effects of this utility model are as follows:

[0014] When the can lid is closed, the annular plate squeezes the push block, which is then driven by the push rod along the arc-shaped guide groove. This pushes the push rod, the annular mounting plate, and the annular sealing ring to move upward and embed into the sealing groove, forming an effective seal. After the can lid is removed, the spring provides a restoring force, causing all components to reset.

[0015] After the fixing rod is inserted into the slot, the rotating locking block allows the J-shaped locking rod to hook onto the fixing rod. The rotating bolt drives the J-shaped locking rod to move down and lock. The three circumferentially distributed locking buckles ensure that the can lid fits tightly with the can body, improving the overall sealing stability. Attached Figure Description

[0029] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0030] Figures 1-12 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figure 1 - Appendix Figure 12 The present invention will be further described below.

[0031] A safety sealing structure for a catalytic cyclization reaction vessel includes a vessel body 1, a vessel cover 2 on the top of the vessel body 1, three fixing rods 3 fixedly installed circumferentially at equal intervals on the outer side of the vessel cover 2, a sealing groove 4 at the bottom of the vessel cover 2, an annular plate 5 fixedly installed at the bottom of the vessel cover 2, an annular mounting groove 6 at the top of the vessel body 1 near the vessel opening, a plurality of adjusting components circumferentially at equal intervals inside the annular mounting groove 6, the adjusting components inside the annular mounting groove 6 penetrating the inner surface of the vessel body 1, a sealing part at the top of the adjusting components, and three locking components circumferentially at equal intervals on the outer side of the vessel body 1 near the vessel opening, the fixing rods 3 cooperating with the locking components.

[0032] In this embodiment, the tank body 1 serves as the main body of the reaction vessel, providing basic support for the entire sealing structure and reaction process, forming a closed reaction space. The tank cover 2 cooperates with the tank body 1 to form a closed system, and its bottom structure provides conditions for sealing. The fixing rod 3 cooperates with the locking assembly, and the locking assembly securely fixes the tank cover 2 to the tank body 1. The sealing groove 4 provides an embedding space for the annular sealing ring 16 of the sealing part, and cooperates with the annular sealing ring 16 to form a sealing surface, enhancing the sealing effect and preventing medium leakage. When the tank cover 2 is closed, the annular plate 5 fits against the lower inner side of the tank body 1. The push block 12 of the adjustment component is moved and squeezed, triggering the linkage between the adjustment component and the sealing part. The annular mounting groove 6 provides installation space for the adjustment component and the sealing part. The adjustment component as a whole, through cooperation with the annular plate 5, converts the pressure of the annular plate 5 into a thrust on the sealing part, thereby realizing the movement of the sealing part. Under the action of the adjustment component, the annular sealing ring 16 of the sealing part is embedded in the sealing groove 4 to form the main sealing structure and prevent the leakage of the reaction medium. The locking component cooperates with the fixing rod 3 to firmly fix the tank cover 2 on the tank body 1 by locking the fixing rod 3, ensuring that the tank cover 2 and the tank body 1 fit tightly.

[0033] Specifically, the adjustment assembly includes two fixing plates 8, which are symmetrically fixed inside the annular mounting groove 6. An arc-shaped guide groove 10 is provided on one side of the fixing plate 8, and a rectangular guide groove 11 is provided on the other side of the fixing plate 8.

[0034] In this embodiment, by symmetrically fixing the fixing plate 8 in the annular mounting groove 6, a foundation is provided for opening the arc-shaped guide groove 10 and the rectangular guide groove 11. The arc-shaped guide groove 10 provides a movement trajectory for the first round rods 17 on both sides of the push rod 13, restricting the movement direction of the push rod 13, so that the push rod 13 can move stably along the arc path, ensuring effective force transmission. At the same time, the length of the arc-shaped guide groove 10 will limit the movement range of the push block 12, preventing the push block 12 from leaving the interior of the movable hole 7. The rectangular guide groove 11 provides a movement trajectory for the second round rods 18 on both sides of the top rod 14, restricting the movement direction of the top rod 14, so that the top rod 14 can move stably in the vertical direction.

[0035] Specifically, the adjustment assembly also includes a movable hole 7, which is located on the inner side of the tank body 1 near the tank opening. The movable hole 7 is connected to the annular mounting groove 6. A push block 12 is movably installed inside the movable hole 7, and a sealing gasket is fixedly installed on the outer side of the push block 12. The push block 12 is used in conjunction with the annular plate 5.

[0036] In this embodiment, the movable hole 7 is opened on the inner side of the tank body 1 near the tank opening and is connected to the annular mounting groove 6, providing a space for the push block 12 to move. In the initial state, the push block 12 protrudes from the movable hole 7 and works in conjunction with the annular plate 5. It moves under the pressure of the annular plate 5, thereby pushing the push rod 13 to move. It is the initial force transmission component in the adjustment assembly. The sealing gasket moves with the push block 12 and fits tightly against the inner wall of the movable hole 7, which helps to enhance the sealing effect at the movable hole 7 and prevents the reaction medium from leaking from the gap between the movable hole 7 and the push block 12.

[0037] Specifically, the adjustment assembly also includes a push rod 13. One end of the push rod 13 is rotatably mounted on the side of the push block 12 near the fixed plate 8. The two sides of the push rod 13 are symmetrically fixedly mounted with first round rods 17, which are movably sleeved inside the arc-shaped guide groove 10.

[0038] In this embodiment, by setting one end of the push rod 13 to be rotatably connected to the push block 12, it can rotate and move under the push of the push block 12, and transmit the force on the push block 12 to the top rod 14. It is the force transmission medium in the adjustment assembly, realizing the effective transmission of force from the push block 12 to the top rod 14. The first round rod 17 is symmetrically fixed on both sides of the push rod 13 and is movably sleeved in the arc-shaped guide groove 10, providing guidance and limit for the movement of the push rod 13, and ensuring that the push rod 13 moves stably along the trajectory of the arc-shaped guide groove 10.

[0039] Specifically, the sealing part includes a top rod 14, which is disposed between two fixed plates 8. Second round rods 18 are symmetrically fixed on both sides of the top rod 14, and the second round rods 18 are movably sleeved inside the rectangular guide groove 11.

[0040] In this embodiment, a push rod 14 is set between two fixed plates 8 to receive the force transmitted by the push rod 13 and transmit the force to the annular mounting plate 15, which pushes the sealing part to move as a whole. The second round rod 18 is symmetrically fixed on both sides of the push rod 14 and is movably sleeved in the rectangular guide groove 11 to provide guidance and constraint for the movement of the push rod 14, ensuring that the push rod 14 moves stably and vertically along the rectangular guide groove 11.

[0041] Specifically, the sealing part also includes an annular mounting plate 15, which is movably fitted inside the annular mounting groove 6. The bottom of the annular mounting plate 15 is fixedly installed with the top of the top rod 14. Several springs 9 are fixedly installed at the bottom of the annular mounting plate 15. The other end of the springs 9 is fixedly installed with the bottom surface inside the annular mounting groove 6. An annular sealing ring 16 is fixedly installed at the top of the annular mounting plate 15. The annular sealing ring 16 is movably fitted inside the sealing groove 4.

[0042] In this embodiment, an annular mounting plate 15 is movably fitted inside an annular mounting groove 6, with its bottom connected to the top rod 14 and its top fitted with an annular sealing ring 16. It can move up and down under the push of the top rod 14, serving to connect the top rod 14 and the annular sealing ring 16. Simultaneously, it provides a mounting carrier for the spring 9. One end of the spring 9 is fixed to the bottom of the annular mounting plate 15, and the other end is fixed to the bottom surface inside the annular mounting groove 6. When the tank cover 2 is removed, it provides a restoring force, causing the annular mounting plate 15, top rod 14, and other components to reset, facilitating the next sealing operation. The annular sealing ring 16 is fixed to the top of the annular mounting plate 15 and movably fitted inside the sealing groove 4. Through its tight fit with the sealing groove 4, it forms the main sealing surface, preventing leakage of the reaction medium.

[0043] Specifically, the locking assembly includes a mounting block 19, which is fixedly installed on the outer side of the tank body 1 near the tank opening. A slot 20 is provided on the top of the mounting block 19, and the fixing rod 3 is movably sleeved inside the slot 20. A locking block 21 is rotatably installed on one side of the mounting block 19, and a mounting hole 22 is provided on the top of the locking block 21.

[0044] In this embodiment, the mounting block 19 is fixed to the outer side of the tank body 1 near the tank opening, providing a mounting base and support for locking components such as the slot 20 and the locking block 21. The slot 20 is opened on the top of the mounting block 19 for the insertion of the fixing rod 3, which serves to position the fixing rod 3. The locking block 21 is rotatably mounted on one side of the mounting block 19, providing an installation position for the mounting hole 22 and subsequent locking components. The position can be adjusted by rotation, which will not obstruct the closing of the tank lid 2, allowing the fixing rod 3 to be smoothly inserted into the slot 20, so that the locking components can accurately act on the fixing rod 3. The mounting hole 22 provides an installation channel and movement space for locking components such as the J-shaped locking rod 23.

[0045] Specifically, the locking assembly also includes a J-shaped locking rod 23, which is movably installed inside the mounting hole 22. The J-shaped locking rod 23 is inverted, and a bolt 25 is rotatably installed on the bottom of the locking block 21. A threaded hole 24 is opened at one end of the J-shaped locking rod 23 near the bolt 25, and the bolt 25 is threadedly connected inside the threaded hole 24.

[0046] In this embodiment, a J-shaped locking rod 23 is movably installed in the mounting hole 22 in an inverted position. Its hook-shaped part can hook onto the fixing rod 3 and can move up and down under the action of the bolt 25 to lock or loosen the fixing rod 3. The bolt 25 is rotatably installed at the bottom of the locking block 21 and is threadedly connected to the threaded hole 24 of the J-shaped locking rod 23. By rotating, the J-shaped locking rod 23 can be moved up and down, thereby adjusting the degree of locking of the J-shaped locking rod 23 onto the fixing rod 3.

[0047] In summary: When using this utility model, firstly, the lid 2 is placed on top of the can body 1, so that the three fixing rods 3 on the outside of the lid 2 are respectively inserted into the slots 20 on the mounting blocks 19 of the three locking components on the outside of the can body 1. At the same time as closing, the annular plate 5 at the bottom of the lid 2 moves downward against the inside of the can opening of the can body 1, gradually contacting and pressing the push block 12 that is initially protruding inside the movable hole 7. After being pressed, the push block 12 moves towards the annular mounting groove 6, and its outer sealing gasket moves with the push block 12 and tightly fits against the inner wall of the movable hole 7, enhancing the sealing performance at the movable hole 7. At the same time as the push block 12 moves, it pushes the push rod 13 that is rotatably connected at one end. The first round rods 17 on both sides of the push rod 13 move along the arc-shaped guide groove 10 on the fixing plate 8, so that the push rod 13 moves along the arc-shaped trajectory towards The top rod 14, located between the two fixed plates 8, is rotated upwards, which in turn pushes the second round rods 18 on both sides of the top rod 14 to move vertically upwards along the rectangular guide groove 11. This causes the annular mounting plate 15, which is fixedly connected at the top, to move upwards within the annular mounting groove 6. The spring 9 at the bottom of the annular mounting plate 15 is stretched, and the annular sealing ring 16 at its top moves upwards and embeds into the sealing groove 4 at the bottom of the can lid 2, forming a tight seal. Then, the locking block 21 is manually rotated so that the J-shaped locking rod 23 on the locking block 21 is aligned with the fixed rod 3. The bolt 25 is then manually rotated, and the bolt 25 is threadedly connected to the threaded hole 24 on the J-shaped locking rod 23. This causes the J-shaped locking rod 23 to move downwards along the mounting hole 22, so that the hook-shaped part of the J-shaped locking rod 23 firmly hooks the fixed rod 3, thus locking the can lid 2 and the can body 1 together.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
