Multi-purpose type packaging double-end-face sealing device for agitated vessel top

The present invention belongs to the mechanical seal, and more particularly relates to a multi-use stirred tank reactor with top cartridge double mechanical seal device. It includes a bearing portion and the sealing portion. Wherein: said bearing portion, a bearing for achieving synchronization with the sealing device; said sealing portion for sealing a gap between the shaft and the reactor kettle. Advantageous Effects: Multi-use stirred tank reactor top with cartridge double seal means to improve performance, low cost, easy operation and maintenance, safe and reliable, using a multi-use with a cartridge double seal means stirred tank reactor top, can completely solve the conventional kettle mechanical seal assembly inconvenient, difficult to replace, service life instability. Practice has proved that this device can be used in chemical, pharmaceutical and food industries production and scientific experiments, both technically, economically and environmentally are entirely feasible.
