Abstract
The utility model provides a mechanical sealing device for a horizontal type stirrer. The mechanical sealing device comprises a sealing structure and a corrugated pipe. The corrugated pipe is arranged on the outer side of the sealing structure. The corrugated pipe is fixedly connected with the sealing structure and an installation flange of the horizontal type stirrer, and is a welded metal corrugated pipe. To prevent the displacement of a shaft from being directly loaded on a mechanical seal, the corrugated pipe is additionally arranged between the mechanical seal and the installation flange of the device; thus, no matter how the shaft changes, the mechanical seal is tightly attached to the shaft all the time, and all changes are absorbed by the corrugated pipe. In addition, the sealing structure matched with the corrugated pipe is arranged according to the function of the corrugated pipe. The sealing effect caused by the axial displacement of the device is avoided.
