Description

Technical Field

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

[0002] As a core piece of equipment in chemical, pharmaceutical, and food industries, the reliability of the lid connection mechanism of a reaction vessel directly affects reaction efficiency, safety, and maintenance costs. During operations such as material addition and equipment maintenance, the lid needs to be opened and closed frequently.

[0003] Most existing reactor lids are fastened with bolts or have a single-axis hinge structure. The former requires tools for disassembly and assembly, which is cumbersome and time-consuming; the latter has a limited opening angle and cannot meet the space requirements under different working conditions. Utility Model Content

[0004] The purpose of this invention is to provide a reaction vessel lid connection mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reactor lid connection mechanism, comprising a reactor body and a lid, wherein an arc plate is fixedly connected to the outer wall of the lid, a connection groove is formed on the surface of the lid, a connection assembly is provided between the reactor body and the lid, the connection assembly includes a hinge plate, the hinge plate is hinged inside the connection groove, a rotating shaft is fixedly connected to the bottom surface of the hinge plate, a fixed seat is rotatably connected to the outer wall of the rotating shaft, and the fixed seat is fixedly connected to the outer wall of the reactor body.

[0006] Preferably, a limiting component is provided on the surface of the reactor body. The limiting component includes an arc-shaped plate with a notch on its side wall. The cover plate is inserted into the arc-shaped plate, and the circular arc plate is inserted into the notch. A connecting rod is fixedly connected to the side wall of the arc-shaped plate, and a sliding plate is fixedly connected to the end of the connecting rod. The side wall of the sliding plate has a through hole, and a guide rod is slidably connected in the through hole. A protrusion is fixedly connected to the end of the guide rod.

[0007] Preferably, the protrusion and the slide plate are elastically connected by a return spring, and the return spring is sleeved on the outer wall of the guide rod.

[0008] Preferably, the cross-section of the arc-shaped plate is L-shaped.

[0010] Preferably, a groove is formed on the surface of the reactor body, and a sealing ring is fixedly connected inside the groove.

[0011] Preferably, the bottom surface of the reactor body is fixedly connected with four sets of arrayed support legs.

[0012] Compared with the prior art, the present invention provides a reaction vessel cover connection mechanism, which has the following advantages:

[0013] 1. The reactor lid connection mechanism, through the composite structure of the hinge plate and the rotating shaft, allows the lid to be opened in two modes: rotation (suitable for daily material addition) and circumferential flipping (rotating around the rotating shaft to the side, suitable for maintenance of large components). Opening and closing can be completed without tools, shortening the operation time for a single person, and is suitable for chemical reaction scenarios that require frequent opening of the lid.

[0014] 2. The reactor lid connection mechanism, after the arc plate is inserted into the notch, the elastic force of the return spring makes the arc plate continuously hug the edge of the lid, which cooperates with the sealing ring to ensure the tight connection between the lid and the reactor body.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a reactor lid connection mechanism, including a reactor body 1 and a lid 2. A groove 11 is formed on the surface of the reactor body 1, and a sealing ring 12 is fixedly connected inside the groove 11. The sealing ring 12 is embedded in the groove 11, forming an annular sealing surface. When the lid 2 is closed, the sealing ring 12 is compressed to prevent leakage of the reaction medium. Four sets of arrayed support legs 13 are fixedly connected to the bottom surface of the reactor body 1, ensuring the vertical stability of the reactor body 1.

[0021] like Figures 1-4As shown, an arc plate 21 is fixedly connected to the outer wall of the cover plate 2. The arc plate 21 is an arc-shaped protrusion on the outer wall of the cover plate 2, which cooperates with the notch 42 of the limiting component 4 to form a radial limiting structure of the cover plate 2. A handle 22 is fixedly connected to the surface of the cover plate 2, which facilitates manual lifting or lowering of the cover plate 2 and optimizes the convenience of operation. A connecting groove 23 is opened on the surface of the cover plate 2. The interior of the connecting groove 23 is used for hinged connection of the connecting component 3, providing a fulcrum for the rotation of the cover plate 2. A connecting component 3 is provided between the reactor body 1 and the cover plate 2. The connecting component 3 includes a hinge plate 31, which is hinged inside the connecting groove 23. A rotating shaft 32 is fixedly connected to the bottom surface of the hinge plate 31. A fixed seat 33 is rotatably connected to the outer wall of the rotating shaft 32. The fixed seat 33 is fixedly connected to the outer wall of the reactor body 1. The hinge plate 31 allows the cover plate 2 to flip up and down, and the rotating shaft 32 allows the cover plate 2 to rotate around the axis of the rotating shaft 32. The fixed seat 33 is welded to the outer wall of the reactor body 1 to provide support for the rotating shaft 32 and ensure the stability of the hinge structure, so that the cover plate 2 can be opened by rotation or flipping.

[0022] like Figures 1-4 As shown, a limiting component 4 is provided on the surface of the reactor body 1. The limiting component 4 includes an arc-shaped plate 41 with an L-shaped cross-section. A notch 42 is provided on the side wall of the arc-shaped plate 41. A cover plate 2 is inserted into the inside of the arc-shaped plate 41, and an arc plate 21 is inserted into the inside of the notch 42. The inner space of the arc-shaped plate 41 accommodates the edge of the cover plate 2. The notch 42 and the arc plate 21 are precisely aligned to form a circumferential limiting. A connecting rod 43 is fixedly connected to the side wall of the arc-shaped plate 41. A sliding plate 44 is fixedly connected to the end of the connecting rod 43. A through hole is opened in the side wall of the sliding plate 44, and a guide rod 45 is slidably connected in the through hole. A protrusion 46 is fixedly connected to the end of the guide rod 45. The protrusion 46 and the sliding plate 44 are elastically connected by a return spring 47, which is sleeved on the outer wall of the guide rod 45. The connecting rod 43 connects the sliding plate 44 and the arc-shaped plate 41 together, so that the two sets move synchronously. The guide rod 45 provides a linear motion track for the slide plate 44 to prevent deviation. The protrusion 46 restricts the sliding stroke of the slide plate 44 and provides support for the end of the return spring 47. During the rotation of the cover plate 2, the arc plate 21 and the inner wall of the arc plate 41 are squeezed, which compresses the return spring 47. As the cover plate 2 continues to rotate, the arc plate 21 and the notch 42 are aligned. The return spring 47 drives the arc plate 41 to return to its original position, thus fixing the cover plate 2.

[0023] In this utility model, when in use, the slide plate 44 is manually pushed along the direction of the guide rod 45 to overcome the elastic force of the return spring 47, so that the arc plate 41 moves laterally away from the cover plate 2 until the arc plate 21 is completely free from the limiting constraint of the notch 42.

[0024] Hold handle 22 and rotate cover 2 upwards to lift it up, disengaging the arc plate 21 from the inner space of the arc plate 41. Flip cover 2 to the side or top of the reactor body 1. Alternatively, hold handle 22 and rotate cover 2, causing cover 2 to rotate around the axis of rotation 32, rotating cover 2 to the side of the reactor body 1.

[0025] When it is necessary to close the cover plate 2, rotate the cover plate 2, the arc plate 21 presses the arc plate 41, pushes the connecting rod 43 to drive the slide plate 44 to slide along the guide rod 45, the return spring 47 is compressed and stored energy, when the arc plate 21 falls completely into the notch 42, the return spring 47 releases the elastic force, pushes the slide plate 44 to return to its original position, and drives the arc plate 41 to move laterally. The inner side wall of the L-shaped structure tightly hugs the edge of the cover plate 2, completing the locking of the cover plate 2.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
