[0002] In a broad sense, a reaction vessel is a container in which physical or chemical reactions occur. It generally includes a vessel body and a vessel lid. During installation, the vessel lid is placed on the vessel body and fixed with bolts.

[0003] Existing reactors typically use bolts or welding to connect the lid and body. During use, these connections are prone to leakage, especially the connection between the body and lid. If the sealing is inadequate, leakage is highly likely.

[0004] A patent publication number CN117695943B was found, entitled "A Leak-proof Reactor with a Discharge Control Structure." The patent specifically discloses a leak-proof reactor with a discharge control structure, comprising a reactor body, a discharge port at the bottom of the reactor, and a discharge assembly inside the reactor for opening and closing the discharge port. The discharge assembly includes several fan-shaped discharge plates rotatably disposed within the reactor, arranged vertically in sequence, with their centers coaxial. When the discharge plates are unfolded, they form a circular plate that closes the discharge port. A moving assembly is disposed outside the reactor to drive the discharge plates to rotate. The moving assembly includes a drive source for driving the discharge plates to rotate, and the rotation angle of the discharge plates controls the opening size of the discharge port.

[0005] Analysis of the publicly available materials shows that the reaction vessel can be leak-proof, but the sealing effect is not good when a fixing structure is added between the vessel body and the lid. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0018] like Figures 1 to 6 As shown: Example

[0019] A leak-proof stainless steel reactor includes a reactor body 1 and a reactor cover 2, and further includes a fixing ring, which comprises an upper fixing ring and a lower fixing ring 4. The upper fixing ring is disposed on the inner side of the reactor cover 2, and the lower fixing ring 4 is disposed on the inner side of the reactor body 1; a groove 9 is disposed on the lower fixing ring 4; a slot 7 is disposed on the upper fixing ring; a sealing gasket 5 is connected to the groove 9 and the slot 7; a wedge ring 6 is disposed on the outer side of the sealing gasket 5; and a locking ring 8 is disposed on the lower end face of the upper fixing ring.

[0020] In this embodiment, the reactor includes a lid 2 and a body 1. The lid 2 and body 1 are separate structures. Fixing rings are provided on the inner surfaces of both the lid 2 and the body 1. The lower fixing ring 4 on the body 1 is provided with a groove 9. The lower end face of the upper fixing ring on the lid 2 is provided with a slot 7. A sealing gasket 5 is provided between the groove 9 and the slot 7. To ensure the stability of the sealing gasket 5, a wedge ring 6 and a locking ring 8 are provided on the outside of the sealing gasket 5. As the lid 2 is continuously pressed down, the locking ring 8 gradually squeezes the wedge ring 6 to compress the sealing gasket 5. Example

[0021] The outer side of the upper fixing ring is fixedly connected to the vessel cover 2, the slot 7 is provided on the lower end surface of the upper fixing ring, and the lower end of the locking ring 8 is lower than the lower end surface of the upper fixing ring.

[0022] Unlike the above embodiments, in this embodiment, the upper fixing ring and the vessel cover 2 are fixedly connected. The slot 7 is set on the lower end face of the upper fixing ring. The slot 7 is a ring structure. The locking ring 8 is lower than the lower end face of the upper fixing ring in the vertical direction, which facilitates the compression of the wedge ring 6. Example

[0023] The outer side of the lower fixing ring 4 is fixedly connected to the vessel body 1, and the groove 9 is provided on the upper end face of the lower fixing ring 4. The position of the slot 7 of the groove 9 corresponds in the vertical direction.

[0024] Unlike the above embodiments, in this embodiment, the upper end face of the lower fixing ring 4 is a groove 9, and a part of the sealing gasket 5 is placed in the groove 9. Example

[0025] The vertical cross-section of the sealing gasket 5 is a T-shaped structure, which is respectively inserted into the groove 9 and the slot 7.

[0026] Unlike the above embodiments, in this embodiment, the sealing gasket 5 has a T-shaped structure, with two wings inserted into the slot 7 and the groove 9 respectively. Example

[0027] The wedge ring 6 has two arc-shaped structures, and the wedge ring 6 is provided with an inclined surface, with the inclined surface facing upward.

[0028] Unlike the above embodiments, in this embodiment, the wedge ring 6 is an arc-shaped structure, not a complete ring, with a gap in the middle, which facilitates movement towards the middle after compression, and the sealing gasket 5 is made of a corrosion-resistant compressible material. Example

[0029] The inclined surface of the wedge ring 6 is directly below the locking ring 8.

[0030] Unlike the above embodiments, in this embodiment, the lower end face of the locking ring 8 faces the inclined surface of the wedge ring 6, which facilitates the inward movement of the wedge ring 6 after compression. Example

[0031] The outer surfaces of the vessel body 1 and the vessel lid 2 are provided with connecting ears 3, and bolt holes are provided on the connecting ears 3.

[0032] Unlike the above embodiments, in this embodiment, the design of the connecting ear 3 facilitates the connection between the lid 2 and the body 1. By tightening the bolts, the locking ring 8 gradually squeezes the wedge ring 6, further stabilizing the sealing gasket 5.

[0033] The working method (or working principle) of this utility model: In operation, a sealing gasket 5 is placed on the lower fixing ring 4 of the vessel body 1. One wing of the sealing gasket 5 is inserted into the groove 9 on the lower fixing ring 4. Then, two wedge rings 6 are placed between the sealing gasket 5 and the vessel body 1. After placing the wedge rings 6, the vessel lid 2 is closed. During the process of closing the vessel lid 2, the upper and lower connecting ears 3 are installed in corresponding positions. At this time, the locking ring 8 contacts the upper inclined surface of the wedge ring 6. Since the inclined surface has a structure that is higher on the inside and lower on the outside, after the bolts are passed through the connecting ears 3 on the vessel lid 2 and the vessel body 1, the locking ring 8 gradually presses down on the wedge ring 6 during the bolt tightening process. During the pressing down process, the wedge ring 6 will squeeze the sealing ring inward. This method can prevent leakage at the sealing gasket 5 due to the high pressure in the reactor.

[0034] In this utility model, unless otherwise explicitly specified and limited, for example, it can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components or an interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
