Abstract
The invention provides a sealing bend switching device of a double-station vacuum refining system. The sealing bend switching device comprises a sealing bend and a bend moving trolley, and further comprises a bend lifting frame and a jacking mechanism. The jacking mechanism is mounted on the bend moving trolley, and the bend lifting frame is mounted on the jacking mechanism. The sealing bend is connected with the bend lifting frame through flexible ropes. The jacking mechanism drives the bend lifting frame to go up and down so as to drive the sealing bend to move up and down. According to the sealing bend switching device, the sealing bend is connected with the bend lifting frame through four-point hanging of the flexible ropes, and due to the fact that the flexible ropes are short and have certain inclination angles, the swing amplitude of the sealing bend in the moving and lifting process can be controlled, and reliable locating and sealing of the sealing bend in switching are facilitated due to flexible connection. Guiding wheels on the bend lifting frame and guiding columns on the bend moving trolley are matched, and therefore it can be guaranteed that the lifting actions of the sealing bend are stable and reliable.
