Abstract

The shaft sealing device comprises a motor base, a motor shaft and a coupler, a sealing sleeve is fixedly installed at the bottom end of the motor base, the bottom end of the sealing sleeve is communicated with a kettle body, the bottom end of the motor shaft is fixedly connected with a driving shaft, and the bottom end of the driving shaft is fixedly connected with a bottom plate; a stirring shaft is fixedly connected to the bottom end of the bottom plate, a sealing ring is attached to the surface of the stirring shaft, and a buffer pad is fixedly mounted on the inner wall of the kettle body. According to the scheme, the sealing ring is matched with the oil pipe, so that the problems of poor sealing performance and low flexibility of the stirring shaft when the stirring shaft of the existing ultrahigh pressure reaction kettle is used are solved, lubricating oil enters the oil pipe through the oil guide hole to be used by the stirring shaft, and the sealing performance of the stirring shaft and the inner cavity of the kettle body is enhanced by the sealing ring; and the pressure reducing hole in the stirring shaft reduces the air pressure between the sealing ring and the stirring shaft, so that the dynamic tightness of the stirring shaft is better, and the practicability of the device is enhanced.

Description

technical field [0001] The invention relates to the technical field of shaft sealing, and more specifically, the invention relates to a shaft sealing device suitable for a stirring shaft of an ultra-high pressure reactor. Background technique [0002] High-pressure reactor is a typical innovation of magnetic transmission device applied to reaction equipment. It fundamentally solves the problem of shaft seal leakage that cannot be overcome by packing seal and mechanical seal before, without any leakage and pollution. The most ideal device for chemical reactions, especially for chemical reactions with flammable, explosive, and toxic media, shows its superiority even more. Ultra-high pressure reactors usually use stirring paddles to fully carry out the media under certain pressure and temperature. Stirring is used for production. Since the medium in the kettle is mostly flammable, explosive or toxic materials, the dynamic seal of the stirring shaft has become the key issue of...
