[0002] There is a feed port on the top of the mixing kettle. When the mixing kettle is mixing some materials, leakage often occurs, which is not conducive to the safety of the mixing kettle and is likely to cause mixing and deterioration in the workplace.

[0003] According to the utility model patent of China with Chinese patent application number 202321336913.1, a new type of mechanical seal magnetic transmission agitator is mentioned. When in use, the new type of mechanical seal magnetic rotating agitator puts raw materials into the feed pipe and uses a sealing plug to ensure the sealing of the reactor. It is a clean, hygienic, good sealing, safe and reliable new type of mechanical seal magnetic transmission agitator. However, when in use, the new type of mechanical seal magnetic transmission agitator manually seals the feed pipe with a sealing plug. The sealing efficiency of this method is low, and it is not guaranteed whether the materials generated inside the stirring kettle during manual sealing will affect human health. The sealing treatment of the feed port is achieved by electric means. Therefore, it is necessary to propose a mechanical seal structure for a stirring kettle to solve the above-mentioned problems.
