The present invention proposes a shaft seal device suitable for the stirring shaft of an ultra-high pressure reactor. Its structure includes a transmission unit, a decompression unit, and an axial force balance unit; The ultra-high pressure is decompressed in sections along the transmission shaft and sealed in sections; the axial load generated by the ultra-high pressure in the reactor is offset by the axial force equalization unit. Based on the working requirements of the ultra-high pressure reactor, the present invention effectively solves the dynamic sealing problem of the ultra-high pressure reactor; adopts a decompression unit to decompress the ultra-high pressure of the reactor along the transmission shaft, and performs segmental sealing, greatly reducing The working pressure of the seal is improved, the working environment of the seal is effectively improved, and the reliability of the dynamic seal is improved; the input load requirement under the reciprocating motion condition is reduced, and energy is saved.
Description
technical field [0001] The invention relates to a shaft sealing device suitable for a stirring shaft of an ultra-high pressure reactor, belonging to the field of chemical equipment. Background technique [0002] Ultra-high pressure reactor is one of the most widely used equipment in petrochemical, military and pharmaceutical industries; It is used for mixing, dispersing, dissolving, crystallizing, extracting, absorbing or desorbing, heat transfer and other operations; the reaction kettle is mainly composed of two parts: a pressure vessel and a mixer, and the pressure vessel includes a kettle body, a kettle cover, a jacket, etc. Components, power source, shaft seal device and stirring paddle constitute the mixer. [0003] The ultra-high pressure reactor is usually produced by fully stirring the medium through the stirring paddle under a certain pressure and temperature. Since the medium in the kettle is mostly flammable, explosive or toxic materials, the dynamic seal of the ...
