Magnetic coupling transmission sealing device with efficient heat exchange system

Abstract

The invention provides a magnetic coupling transmission sealing device with an efficient heat exchange system. The device solves the technical problem that an existing magnetic coupling transmission sealing device is difficult to apply to a large stirring system. The device comprises an external magnetic steel assembly, a sealing cover body assembly, an internal magnetic steel assembly, an upper transmission shaft and a bearing set; and internal heat exchange assemblies are arranged outside the upper transmission shaft and the bearing set in a sleeving mode, an external heat exchange assemblyis arranged outside the external magnetic steel assembly, the lower end of the external heat exchange assembly is connected with the sealing cover body assembly and a reaction kettle connecting flange, and upper liquid sealing assemblies are connected with the external heat exchange assembly and the upper end of the external magnetic steel assembly. The device is widely applied to the technical field of stirring reaction kettles.

Description

technical field [0001] The invention relates to a sealing device for a stirring reaction kettle, in particular to a magnetic coupling transmission sealing device with a high-efficiency heat exchange system. Background technique [0002] With the rapid development of fine chemical industries such as food, medicine, organic synthesis, petrochemical and environmental protection industries, the trend of large-scale equipment development is strong, but the development trend is often limited by certain specific technologies, such as large-scale stirring reactors The limitation lies in the sealing of the stirring system. The large-scale stirring reactor will inevitably increase the volume. If the stirring system is enlarged, the sealing system sealed with it will also be enlarged. The increase in volume indicates the energy contained in the medium inside the container. also increased accordingly. The requirements for stirring and stirring reaction process of some flammable, explos...

[0002] With the rapid development of fine chemical industries such as food, medicine, organic synthesis, petrochemical and environmental protection industries, the trend of large-scale equipment development is strong, but the development trend is often limited by certain specific technologies, such as large-scale stirring reactors The limitation lies in the sealing of the stirring system. The large-scale stirring reactor will inevitably increase the volume. If the stirring system is enlarged, the sealing system sealed with it will also be enlarged. The increase in volume indicates the energy contained in the medium inside the container. also increased accordingly

The requirements for stirring and stirring reaction process of some flammable, explosive, toxic, corrosive and precious metal media are becoming more and more strict, and the requirements for the stirred tank or s
