Sealing structure of a reactor for chemical production

Abstract

The invention relates to the technical field of chemical production reaction kettles, in particular to a sealing structure of a reaction kettle for chemical production, which includes a reaction kettle body and a feeding pipe. The top of the reaction kettle body is connected with a sealing cover through an installation mechanism. There is a rotating port, the inner wall of the rotating port is rotatably connected with a casing, the top of the casing is connected with a limit mechanism, and the top of the reactor body is rotatably connected with four threaded rods, and the four threaded rods are equidistantly arranged on the outer wall of the casing , the top of the threaded rod runs through the sealing cover, and the threaded rod is connected with the casing through an engaging mechanism. The present invention is used through the cooperation of the turntable, the sleeve, the first gear, the second gear, the threaded rod, the threaded block, the movable rod, the connection mechanism, the connecting groove, the slide rod, the first return spring and the movable plate, and the rotation of the sleeve makes the The sealing sleeve seals the feeding pipe, and the sealing sleeve is squeezed through the movable plate to strengthen the sealing between the sealing sleeve and the feeding pipe.

Description

Technical field [0001] The present invention relates to the field of chemical production reactor technology, in particular to a chemical production reactor sealing structure. Background [0002] The reactor is a vessel for physical or chemical reactions, through the structural design and parameter configuration of the container, to achieve the process requirements of heating, evaporation, cooling and other functions, is widely used in various fields of testing process pressure vessel. The opening sealing effect of the ordinary reactor is not good, and after sealing the opening, it is also necessary to fine-tune to improve the sealing performance of the kettle body, the structure is complex, and the operation is inconvenient. [0003] In some chemical reaction processes, especially some high-temperature free radical reactions, the need to highly isolate the air, especially the oxygen in the air, the current laboratory mostly use mercury tank that is, mercury tank sealing method, ...

AI Technical Summary

Problems solved by technology

The sealing effect of the opening of the ordinary reactor is not good. After sealing the opening, it needs to be fine-tuned to improve the sealing performance of the kettle body. The structure is complex and the operation is inconvenient.

[0003] In some chemical and chemical reaction processes, especially some high-temperature free radical reactions, a high degree of isolation of air, especially oxygen in the air, is required. At present, the method of sealing the mercury tank is mostly used in the laboratory, and graphite metal or ceramics are mostly used in the industry. For the former, although the sealing effect is good, because mercury is not resistant to high temperature, especially some reaction vessels with a reaction temperature above 300°C-400°C, it is easy to evaporate mercury, resulting in Adverse environmental impact, for the latter, the sealing structure at the opening of most reactors currently has only one layer of sealing ring, which will cause aging of the sealing ring after long-term use, affect the sealing effect, and cause leakage, so it is urgently needed A sealing structure of a reaction kettle used in chemical production to solve the problem
