Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a reaction vessel sealing device. Background Technology

[0002] Reactors are core equipment widely used in chemical, pharmaceutical, and food industries for material mixing, reaction, distillation, and other processes. Currently, the sealing structure of a reactor typically includes a fixed frame and a sealing cover. The sealing cover is connected to the fixed frame via hinges or shafts, and a tight seal is achieved between the sealing cover and the fixed frame through snaps, bolts, or clamping mechanisms. However, existing reactor sealing devices have the following shortcomings in practical applications: (1) Since the sealing cover of the reactor usually has a large mass, it is easy for the sealing cover to fall rapidly or open suddenly under the action of gravity during the opening or closing process, generating a large impact force. This not only easily causes mechanical collision damage between the sealing cover and the fixed frame, shortening the service life of the equipment, but also poses a safety hazard of injuring the operators.

[0003] (2) Most existing sealing and clamping mechanisms use fixed bolt connections. Although fixed bolt connections provide reliable sealing, they are cumbersome to operate and have low opening and closing efficiency.

[0004] (3) The existing damping mechanism and sealing mechanism lack structural integration design, resulting in a complex overall structure, a large number of parts, high manufacturing cost, and is not conducive to the daily use of the equipment. Utility Model Content

[0005] In order to solve the technical problems existing in the background art, the present invention provides a reaction vessel sealing device, which can provide a smooth buffer for the opening and closing of the sealing cover, and can also firmly press the sealing cover onto the fixed frame.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A reaction vessel sealing device, comprising: Fixed frame; A sealing cap that can be opened and closed is attached to a fixed frame; A damping mechanism, connected between the fixed frame and the sealing cover, is used to provide buffer damping for the opening and closing of the sealing cover; A sealing mechanism, connected between the fixed frame and the sealing cover, is used to seal the fixed frame and the sealing cover.

[0007] Furthermore, the damping mechanism includes: The first connector is fixedly mounted on the sealing cover; The second connector is fixedly mounted on the fixed frame and hinged to the first connector. A damper is connected between the first connector and the second connector.

[0008] Furthermore, the main body of the damper is rotatably connected to the second connecting member, and the telescopic rod of the damper is rotatably connected to the circular hole opened on the first connecting member.

[0009] Furthermore, the first connector has an elongated hole, and the second connector has a rotating shaft that mates with the elongated hole.

[0010] Furthermore, the sealing mechanism includes: The base is fixedly mounted on the fixed frame. Stud, hinged to the base; The movable block is slidably fitted onto the stud; The nut is threaded onto the stud and is located on the side of the movable block away from the base.

[0011] Furthermore, the sealing cover has a slot, and the movable block has a hook that mates with the slot.

[0012] Furthermore, a sealing gasket is provided between the fixing frame and the sealing cover.

[0013] The beneficial effects of this utility model are: (1) By setting a damping mechanism between the fixed frame and the sealing cover, a buffer damping force is provided during the opening and closing of the sealing cover, which effectively prevents the sealing cover from rapidly flipping or violently impacting due to gravity or external force, thus avoiding equipment damage and operator injury, and significantly improving the safety and stability of operation.

[0014] (2) The sealing mechanism, through the cooperation of studs, movable blocks and nuts, can apply a continuous and uniform clamping force to the sealing cover, ensuring that the sealing gasket between the sealing cover and the fixed frame is always in a good compressed state, effectively preventing the leakage of the medium in the reactor, and ensuring the safety and stability of the reaction process.

[0015] (3) The damping mechanism achieves smooth opening and closing of the sealing cover through the hinge structure of the first and second connecting parts and the cooperation of the elongated hole and the rotating shaft. In addition, the elongated hole can also provide the necessary longitudinal displacement margin for the sealing cover, ensuring that it can fit tightly against the fixed frame in the closed state.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1 As shown, a reaction vessel sealing device includes a fixed frame 1 for fixed connection to the reaction vessel body. A sealing cover 2 is closable and connected to the fixed frame 1 to enable the reaction vessel to open and close. A damping mechanism 3 is connected between the fixed frame 1 and the sealing cover 2 to provide buffer damping for the opening and closing of the sealing cover 2. A sealing mechanism 4 is connected between the fixed frame 1 and the sealing cover 2 to seal the fixed frame 1 and the sealing cover 2, ensuring the reaction vessel's airtightness. A sealing gasket is provided between the fixed frame 1 and the sealing cover 2 to further enhance the sealing effect.

[0021] like Figure 2 , 3 As shown, the damping mechanism 3 includes a first connecting member 301 and a second connecting member 302. The first connecting member 301 is fixedly mounted on the sealing cover 2. The second connecting member 302 is fixedly mounted on the fixed frame 1 and hinged to the first connecting member 301, thereby allowing the sealing cover 2 to rotate and open relative to the fixed frame 1. A damper 303 is connected between the first connecting member 301 and the second connecting member 302. The damper 303 is preferably a hydraulic damper or a pneumatic damper, which is connected between the first connecting member 301 and the second connecting member 302 to provide a controllable damping force. This effectively prevents the sealing cover 2 from rapidly flipping or violently impacting due to gravity or external forces, avoiding equipment damage and operator injury, and significantly improving operational safety and stability.

[0022] In a specific embodiment, the main body of the damper 303 is rotatably connected to the second connecting member 302, and the telescopic rod of the damper 303 is rotatably connected to the circular hole 3011 opened on the first connecting member 301. Furthermore, to accommodate changes in the distance and angle between the first connecting member 301 and the second connecting member 302 during the opening and closing of the sealing cover 2, the first connecting member 301 has an elongated hole 3012, and the second connecting member 302 is provided with a rotating shaft that mates with the elongated hole 3012. The damping mechanism 3, through the hinged structure of the first connecting member 301 and the second connecting member 302, combined with the engagement of the elongated hole 3012 and the rotating shaft, achieves smooth opening and closing of the sealing cover 2. Moreover, the elongated hole 3012 also provides the necessary longitudinal displacement margin for the sealing cover 2, ensuring that it can tightly fit the fixed frame 1 in the closed state.

[0023] like Figure 4 As shown, the sealing mechanism 4 includes a base 401, which is fixedly mounted on the fixed frame 1. A stud 402 is hinged to the base 401. A movable block 403 is slidably fitted onto the stud 402. A nut 404 is threaded onto the stud 402 and located on the side of the movable block 403 away from the base 401. By tightening the nut 404, the movable block 403 can be pushed towards the base 401. The sealing mechanism 4 can apply a continuous and uniform clamping force to the sealing cover 2, ensuring that the sealing gasket between the sealing cover 2 and the fixed frame 1 is always in a good compressed state, effectively preventing leakage of the medium inside the reactor and ensuring the safety and stability of the reaction process.

[0024] In a specific embodiment, the edge of the sealing cover 2 is provided with a groove 405, and the movable block 403 is provided with a hook that cooperates with the groove 405. After the sealing cover 2 is closed, the operator can align the hook of the movable block 403 and engage it in the groove 405 of the sealing cover 2. Then, tighten the nut 404, which pushes the movable block 403 to slide along the stud 402, causing the hook to abut against the groove 405, thereby firmly pressing the sealing cover 2 onto the fixed frame 1 to achieve a reliable seal.

[0025] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
