The invention discloses an online replacement device for a dynamic sealing mechanism of a tank body. The technical problem of shutdown loss caused by shutdown of the whole production line of an enterprise due to shutdown for replacement of the dynamic sealing mechanism in the prior art is solved. The device comprises a sealing seat, a stirring shaft abdicating hole is formed in the sealing seat, asealing cavity is formed in the upper portion of the stirring shaft receding hole, a stirring shaft sealing plate located in the sealing cavity is arranged on the stirring shaft, a shaft clamp for limiting the stirring shaft sealing plate is arranged in the sealing cavity, and an O-shaped sealing ring matched with the stirring shaft sealing plate to seal the stirring shaft receding hole is arranged on the bottom surface of the sealing cavity. The device can replace the dynamic sealing mechanism on a stirring tank (kettle) device under an online working condition, can effectively prevent production halt losses brought to enterprises due to replacement of the dynamic sealing mechanism under the production halt working condition like a traditional mode, increases the replacement efficiency of the dynamic sealing mechanism, and eliminates potential safety hazards caused by insufficient replacement of media in the tank when the dynamic sealing mechanism is replaced like the traditional mode.
Description
technical field [0001] The invention belongs to the technical fields of chemical industry, light industry and smelting machinery, and in particular relates to an online replacement device for a dynamic sealing mechanism of a tank body. Background technique [0002] Mixing tank (kettle) equipment is widely used in modern industries such as chemical industry, light industry, smelting, pharmaceutical and other industries. Since the mixing tank equipment has a tank body and a stirring mechanism, when most of the working conditions such as pressure, temperature, and medium characteristics reach dangerous values, it is necessary to design a dynamic sealing mechanism between the tank body and the stirring shaft system. The dynamic sealing mechanism is divided into packing seal, mechanical seal, magnetic seal, magnetic fluid seal and other methods. The role of the seal is mainly to overcome the following defects during the transmission process of the stirring shaft: [0003] (1) P...
