Description

Technical Field

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

[0002] A reaction vessel is a container widely used in chemical, pharmaceutical, and food industries, primarily for the mixing, reaction, heating, and cooling of materials. It typically consists of a vessel body, a stirring system, heating or cooling devices, a transmission system, and sealing components. By precisely controlling parameters such as temperature, pressure, and stirring rate, it ensures the efficient execution of chemical reactions or physical processes.

[0003] The sealing performance of a reactor is one of the key factors affecting its safety and stability, especially in scenarios involving flammable, explosive, toxic, harmful, or high-purity materials. The sealing effect is directly related to production safety, product quality, and environmental risk control.

[0004] In practical applications, the existing sealing cover structure of the reactor is difficult to withstand the impact of extreme environments under high pressure, high temperature or high corrosive conditions, resulting in poor sealing performance, easy gas leakage, and limiting the stable operation of the reactor under extreme conditions. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a sealing cover for a reaction vessel, which solves the problem that conventional sealing structures cannot withstand the impact of extreme environments, resulting in poor sealing and easy gas leakage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing cover for a reactor, comprising a reactor inlet, a first sealing cover rotatably mounted on the top of the reactor inlet, the first sealing cover being fixed to the top of the reactor inlet by bolts, a first threaded rod threadedly connected to the center of the first sealing cover, a first shaft locking device for locking and fixing the first threaded rod on the first sealing cover, a second sealing cover connected to the bottom of the first threaded rod, a second fixing ring on the inner wall of the reactor inlet, a plurality of sealing rings between the second fixing ring and the second sealing cover, a plurality of second threaded rods threadedly connected to the first sealing cover for pressing against the top of the second sealing cover, and a plurality of second shaft locking devices for locking and fixing the second threaded rods on the top of the first sealing cover.

[0007] Preferably, a first fixing ring is provided on the outer wall of the feed inlet of the reactor, and the first sealing cover is bolted to the first fixing ring.

[0008] Preferably, a handwheel is provided at the top of the first threaded rod.

[0009] Preferably, a fixing block is provided on the outer wall of the feed inlet of the reactor, and the first sealing cover is rotatably connected to the fixing block.

[0010] This utility model provides a sealing cover for a reaction vessel, which has the following beneficial effects:

[0011] This invention uses a first threaded rod to drive a second sealing cover to seal the inner side of a second fixing ring. A first shaft locking device is used to lock and fix the first threaded rod. Then, multiple second threaded rods are pressed onto the edge of the upper surface of the second sealing cover to further improve the stability of the second sealing cover and prevent airtightness in extreme environments.

[0016] In this embodiment, a first threaded hole is provided at the center of the first sealing cover 3, and a first threaded rod 8 is provided through the first threaded hole. When the first threaded rod 8 is screwed on, the rotating first threaded rod 8 can drive the second sealing cover 6 connected to the bottom to rotate and move in the vertical direction. The second sealing cover 6 is integrally formed by an upper disc and a lower boss. The top of the disc is connected to the bottom end of the first threaded rod 8. The boss can be embedded in the inner ring of the second fixing ring 5. The boss and the inner ring of the second fixing ring 5 are matched. Several mounting grooves are provided on the top of the second fixing ring 5 and the side wall of the boss. The sealing ring 7 is fixedly provided in the mounting groove.
